     TECHNICAL FIELD 
     This invention relates to a foam dispensing container that dispenses a liquid agent into foam, and a foam dispenser attachment used for the foam dispensing container. 
     BACKGROUND ART 
     There has been proposed a container (foam dispensing container) designed to dispense, from a container body, a various types of liquid materials (liquid agents) including hand soap, face wash, dishwashing detergent, hairdressing agent into foam after mixing them with air. For example, Patent Literature 1 describes a container with a foaming pump, designed to dispense a liquid agent housed in the container body into foam, when a nozzle head is pressed down. The container has a foam dispensing adapter having discretely arranged thereon a plurality of circular outlets according to a triangular or pentagonal layout at the vertexes and the center. The foam dispensing adapter is detachably attached to the nozzle head so as to be capped thereon from the top. In the container, positions and diameter of the outlets are determined so as to build up a foam object modeled after a character, as a result of crowding of foam lumps dispensed through a plurality of outlets. 
     Patent Literature 2 describes an aerosol container that jets, from a container body containing a liquid agent and a pressurizing gas, such liquid agent into a foamy or gel-like matter. By pressing the nozzle head down, the outlet is opened, and the liquid agent having been filled under pressure is jetted powerfully to produce foam or gel, to build up a spaghetti- or band-like contiguous geometry. The nozzle head has formed therethrough a plurality of flow channels through which the liquid agent is dispensed, and the outlet corresponds to each of these flow channels. Patent Literature 2 proposes various types of the outlet. More specifically, a plurality of outlets shaped like slit, rectangle, circle, star and so forth are discretely arranged over the face of the nozzle head. With such design, plural lines of foam or gel with a contiguous geometry will be dispensed. 
     The containers described in Patent Literature 1 and Patent Literature 2 were designed to dispense the foamy liquid agent through the outlets with the aid of the mechanical foaming pump or pressurizing gas, when the user presses down the nozzle head. Meanwhile, Patent Literature 3 describes a device that dispenses a liquid agent into foam, with the aid of an electrically actuated pump. The pump has an electrically reciprocated piston, which is activated upon detection of approach of the user&#39;s hand by a sensor, and quantitatively dispenses a predetermined amount of liquid agent. The liquid agent is dispensed through a round open nozzle in the form of liquid or foam.

     SUMMARY OF THE INVENTION 
     Technical Problem 
     By dispensing the liquid agent in a foamy manner, the user can quickly use it for cleansing or the like, without need of foaming it by hands. The container of Patent Literature 1 can build up the dispensed foam modeled after characters, posing an advantage of being joyful to see, not only for the convenience of cleansing. 
     The container of Patent Literature 1 can, however, only build the foam object with a relatively simple shape based on combination of several spherical lumps of foam, since the container merely has the circular outlets at a plural points. It is therefore difficult for the container of Patent Literature 1 to build up a finely-profiled foam object with the intended shape in various ways. 
     The container of Patent Literature 2 is an aerosol container for jetting foamy or gel-type liquid agent through a plurality of outlets to build up the spaghetti-like or band-like contiguous geometry, and the liquid agent having been filled under pressure is jetted powerfully in the form of foam or gel. It is therefore difficult for the container of Patent Literature 2 to build up a foam object with the intended shape modeled after characters of so, unlike the container of Patent Literature 1. 
     There is therefore a need for building up the liquid agent dispensed into foam with finely-profiled intended shape. 
     Solution to Problem 
     This invention is to provide a foam dispensing container that includes a container body that reserves a liquid agent; a head part that has an outlet, and dispenses the liquid agent delivered from the container body through the outlet into foam; and a dispensing operation part that allows dispensing of a predetermined amount of the foamy liquid agent through the outlet each time it accepts a user&#39;s operation, the outlet being an opening with a contiguous geometry narrowed from an intended shape, and being designed to build up the foamy liquid agent, dispensed through the outlet as a result of a single or multiple operations made on the dispensing operation part, into the intended shape in a plan view seen in the dispensing direction. 
     This invention is also to provide a foam dispenser attachment used while attached detachably to a nozzle part of a foam dispensing container that includes a container body that reserves a liquid agent; a nozzle part that has a nozzle opening, and dispenses the liquid agent delivered from the container body through the nozzle opening into foam; and a dispensing operation part that allows dispensing of a predetermined amount of the foamy liquid agent through the nozzle opening each time it accepts a user&#39;s operation, the foam dispenser attachment having an outlet with a contiguous geometry narrowed from an intended shape, and being designed to accept the foamy liquid agent dispensed through the nozzle opening and to dispense it through the outlet to thereby build up a foam object with the intended shape. 
     Advantageous Effects of Invention 
     According to the foam dispensing container, and the foam dispenser attachment used for such foam dispensing container of this invention, the outlet is opened to have a contiguous geometry narrowed from the intended shape, so that the dispensed foam swells in the width direction to be built up to such intended shape in a plan view. This invention can therefore build up the foam object with the intended shape in a finely profiled manner.

     DESCRIPTION OF EMBODIMENTS 
     Embodiments of this invention will be explained below referring to the attached drawings. In all drawings, all similar constituents will be given the same reference signs to properly skip repetitive explanation. 
     First Embodiment 
       FIG. 1  is a top perspective view illustrating a foam dispensing container  100  according to a first embodiment of this invention, and  FIG. 2  is a bottom perspective view of the foam dispensing container  100 .  FIG. 3A  is a plan view illustrating a foam object FB dispensed out from the foam dispensing container  100  of this embodiment, and  FIG. 3B  is a front elevation of the foam object FB. 
     The foam dispensing container  100  of this embodiment has a container body  40  that reserves a liquid agent L, a head part  30  having an outlet  20 , and a dispensing operation part (pump head part  32 ). The head part  30  dispenses the liquid agent L delivered from the container body  40  through the outlet  20  into foam. The dispensing operation part (pump head part  32 ) allows dispensing of a predetermined amount of foamy liquid agent (foam B) through the outlet  20 , each time it accepts a user&#39;s operation. In this way, the foam object FB with a desired intended shape as illustrated in  FIG. 3A  is built. 
     The outlet  20  of this embodiment is formed to have such contiguous geometry narrowed from the intended shape. The foamy liquid agent (foam B) dispensed through the outlet  20 , as a result of a single or multiple operations made on the dispensing operation part (pump head part  32 ), is built up into an intended shape in a plan view seen in the dispensing direction. 
     The foam dispensing container  100  will be further detailed below. In this specification, with the container body  40  stood upright, the side the head part  30  positioned relative to the container body  40  will be denoted as “top” or “upper side”, and the opposite side will be denoted as “bottom” or “lower side”. Such vertical direction does not always necessarily agree with the perpendicular direction. For the convenience, among horizontal directions that cross normally to the top-bottom direction, the direction connecting the container body  40  and the outlet  20  will occasionally be referred to as “distal-proximal direction”, and the side of the container body  40  closer to the outlet  20  referred to as “distal side”. 
     The foam dispensing container  100  is a container capable of dispensing the liquid agent L, reserved in a liquid form in the container body  40 , after transforming it into foamy article. Although the liquid agent L is now represented by a hand soap, it may also be exemplified, without being limited thereto, by various products used in a foamy form, including face-wash, cleanser, dishwashing detergent, hairdressing, body soap, shaving cream, skin cosmetics such as foundation, hair dyes, and foods such as whipped cream. 
     The foam dispensing container  100  is a container capable of dispensing the liquid agent L from the container body  40 , upon being actuated mechanically or electrically. When roughly itemized, the foam dispensing container  100  is composed of the container body  40  that reserves the liquid agent L, and a nozzle assembly  50  (foam delivery mechanism  50 ) that is attached to the container body  40  and is used for dispensing the liquid agent L. 
     The liquid agent L is reserved in the container body  40  at normal pressure or under pressure. The foam dispensing container  100  transforms the liquid agent L into foam, by bringing the liquid agent L reserved at normal pressure into contact with air, or reducing the pressure around the liquid agent L reserved under pressure. In this specification, the foamy liquid agent L will occasionally be referred to as “foam B”, for the convenience of discriminating it from the non-foamy liquid agent L reserved in the container body  40 . 
     The foam dispensing container  100  of this embodiment is, as described later, a mechanical pumping container by which the liquid agent L reserved in the container body  40  at normal pressure is sucked up through a suction tube  57 , when a piston  55  (see  FIG. 4 ) is driven by a press-down operation made on the pump head part  32 . 
     The container body  40  has a bottle form, and has a hollow trunk  42 , and a bottleneck  44  formed on the top end of the trunk  42  so as to shrink the diameter. Geometry and inner volume of the container body  40  are not specifically limited. The container body  40  is made of a synthetic resin. Now the liquid agent L (foam B) may be dispensed, alternatively to this embodiment, typically with the aid of a pressurized gas contained in a bomb, such as aerosol product, or with the aid of an electrically actuated motor  98  (see  FIG. 15  and  FIG. 28 ), so long as a predetermined amount of foam B can be dispensed each time the user&#39;s operation is accepted. 
     The outlet  20  is an opening through which the form B is dispensed outside the foam dispensing container  100 . The head part  30  is a term collectively denoting portions that form a flow channel of the liquid agent L or foam B outside the container body  40 , and encompasses the outlet  20 . 
     The outlet  20  is formed so as to be opened downward in a bottom face  31  of the head part  30 , specifically at a portion thereof projected laterally from the bottleneck  44  of the container body  40 . The dispensing direction of the foam B dispensed through the outlet  20  is downward, and downward visual viewing will be referred to as “plan view”. The foam B, when dispensed through the outlet  20  and released to the atmospheric pressure, will be locally swelled in the individual portions, while keeping as a whole the geometry of the outlet  20 . In this way, the foam B will be built up into the foam object with an intended shape FB on the user&#39;s palm H (see  FIG. 3A ) or on various application tools such as sponge or brush. 
     The head part  30  of this embodiment has a dispensing guide  26  having the outlet  20  on the bottom end thereof. The dispensing guide  26  is provided so as to extend below the head part  30  (more specifically a reservoir  60 , see  FIG. 6 ), and has a straight pipe-like throughhole that is formed in the same geometry with the outlet  20 . The dispensing guide  26  in this embodiment is provided so as to suspend down from the head part  30  and is formed like a wall that surrounds the outlet  20 . 
     The form B dispensed through the head part  30  is rectified as a whole after allowed to pass through the dispensing guide  26 . In this way, the dispensed foam B is prevented from swelling in the widthwise direction, and thereby the foam object FB is suitably formed into the predetermined intended shape. 
     The dispensing guide  26  in this embodiment is formed so as to suspend down from the head part  30  and is formed like a wall. This beneficially prevents the dispensed foam B from adhering onto the undersurface of the head part  30 , making it possible to improve release of the foam B, and to build up a well-profiled foam object FB. This invention is, however, not limited thereto, and wherein the dispensing guide  26  may be formed so as to be buried in the wall of the bottom face  31  of the head part  30 . A possible case where the dispensing guide  26  is buried in the wall of the bottom face  31 , may be such that the bottom face  31  is made thick enough, and a through-hole formed so as to extend through the bottom face  31  may be used as the dispensing guide  26 . In this case, from the viewpoint of improving release of the foam B dispensed through the dispensing guide  26  formed so as to extend through the bottom face  31 , it is possible to carve bottom face  31  (that is, the undersurface of the head part  30 ) to form a trench-like recess with a predetermined depth around the dispensing guide  26 . By forming the recess close to the dispensing guide  26 , the dispensing guide  26  will eventually be surrounded by a thin wall, and can thereby reduce the amount of foam B probably adhere onto the bottom face  31  of the head part  30 . 
     Width (aperture) and geometry of the outlet  20  are determined so that the foam object FB with intended shape may be built up, when the foam B was dispensed onto the dispensing target plane TP positioned a predetermined distance SP (see  FIG. 21 ) below the level of the outlet  20  upon completion of dispensing of the foam B. The level of the outlet  20  upon completion of dispensing of the foam B is a level of the outlet  20  when the pump head part  32  was pressed down to reach the lower limit position. 
     The intended shape of the foam object FB may be any of planar icons (pictures) representing letters, graphics and symbols. That is, the phrase stating that “the foamy liquid agent (foam B) is built up into an intended shape in a plan view seen in the dispensing direction, as a result of operation made on the dispensing operation part” means that the foam object FB, having a shape of a predetermined form in a plan view in the dispensed direction, is built on the dispensing target plane TP positioned a predetermined distance SP below the level of the outlet  20  upon completion of dispensing of the foam B. The foam object FB is formed into a three-dimensional shape having a predetermined thickness, on the dispensing target plane TP such as palm H. Such three-dimensional shape is recognized to be the above-described intended shape in a plan view in the dispensing direction. 
     Graphics of the intended shape is exemplified by those of animal, plant, human, animation character, geometrical shape, and pattern. 
     As illustrated in  FIG. 1 , the head part  30  has embossed on the top face thereof a pattern indication  15  that corresponds to the intended shape of the foam object FG (see  FIG. 3A ) built up with the dispensed foam B seen in a plan view. In this embodiment, a musical note symbol (eighth note) is illustrated as an example of the intended shape of the foam object FB. The user can easily discriminate, at a glance, a plurality of types of the foam dispensing containers  100  whose geometries of the outlets  20  are different. 
     The outlet  20  of this embodiment is formed as an opening having a contiguous geometry narrowed from the intended shape that is a plan view of the foam object FB. Now the phrase stating that the “intended shape is narrowed” means that the widths of the individual portions composing the intended shape are shrunk along the contour of the intended shape, or are shrunk so as to fill up the inside of the intended shape. The phrase stating that the “outlet  20  has a contiguous geometry” means that at least a partial area of the outlet  20  has a linear form whose length is sufficiently larger than the width. Representatively, the linear form is preferably a contiguous long shape, but the linear form is not limited thereto, and also includes embodiments having a plurality of discrete elements (openings) closely juxtaposed in the longitudinal direction, which are exemplified by the forms of broken line and chain line. More specifically, unlike the container of Patent Literature 1 by which an intended shape is stippled by using a plurality of outlets distributed two-dimensionally, the outlet  20  of this embodiment draws at least a part of the intended shape like a line drawing, by aid of the contiguous geometry that contains a long linear portion. Such linear portion may be a contiguous opening, or may be discrete openings arranged in line. In the description below, the term “linear” will be used to encompass a mode representing a continuous line, and a mode representing discrete elements arranged in line to give a broken line, chain line and so forth. The phrase stating that “the outlet  20  has a contiguous geometry narrowed from the intended shape” means that linear portions of the outlet  20  are arranged along the contour of the intended shape, or so as to fill the inside of the intended shape, for the purpose of building up the intended shape using the foam B that swells after dispensed. 
     For the purpose of building up, with the foam B, a lump of intended shape which outlines the plan view geometry of the foam object FB, the outlet  20  may be given as an opening with an integrated contiguous geometry. Alternatively, each of a plurality of partial outlets has a contiguous geometry, and these partial outlet may be combined to give the outlet  20 . Each of the outlets  20  according to this embodiment and the later-described first to third modified examples (see  FIG. 11A  to  FIG. 13A ) is integrally formed. Meanwhile the outlet  20  according to the fourth modified example (see  FIG. 14A ) is configured by combining narrowly-opened parts  22   a ,  22   b  which correspond to the partial outlet. 
     By forming the outlet  20  with a contiguous geometry as seen in the foam dispensing container  100  of this embodiment, the outlet  20 , even if partially clogged, can sustainably dispense the foam B from both sides of the clogged portion. This is beneficial to avoid dispensing failure of the foam B, due to total clogging of the outlet  20 . A possible cause of clogging of the outlet  20  is such that a residue of the foam B in the head part  30  may return after elapse of a certain period of time into the liquid agent L in liquid form, and can further promote solidification. However, by making the outlet  20  with a contiguous geometry, is now possible to prevent the total clogging of the outlet  20 , even if a long duration of time elapsed after the foam B was dispensed and before the next dispensing operation, and the outlet  20  should be partially clogged. In other words, even if the liquid agent L contains an ingredient that is likely to solidify, it now becomes possible to dispense the foam B while reducing a risk of clogging of the outlet  20 . By dispensing the foam B through opening portions adjoining to the locally clogged portion of the outlet  20 , the solidified moiety that caused clogging may be expelled from the outlet  20  in such a way entrained by the dispensed foam B. In particular, as a result of contiguousness of formation of the narrowly-opened part  22  and the widely-opened part  24  as seen in this embodiment, even if the narrowly-opened part  22  should be partially clogged, the clogging at the narrowly-opened part  22  may be resolved by dispensing the form B through the widely-opened part  24 . From this point of view, the outlet  20  preferably has a pair of widely-opened parts  24  ( 24   a ,  24   b ) on both ends of the narrowly-opened part  22  (see  FIG. 11A ). 
     The foam dispensing container  100  dispenses a predetermined amount of foam B through the outlet  20  each time the dispensing operation part (pump head part  32 ) is operated. Now the phrase stating that “a predetermined amount of foam B is dispensed” conceptually exclude that “foam B is unlimitedly and continuously dispensed”, so that the amount of foam B dispensed through the outlet  20  per operation made on the dispensing operation part (pump head part  32 ) is not always necessarily constant in a strict sense. “A predetermined amount of foam B dispensed through the outlet  20 ” means a bulk volume of foam B delivered through the outlet  20 , when the dispensing operation part (pump head part  32 ) is operated, with the flow channel inside a nozzle assembly  50  (see  FIG. 4 ) including the head part  30  preliminarily filled with the foam B to the full. Such predetermined amount is the amount preliminarily and roughly given by conditions including the structure of the nozzle assembly (foam delivery mechanism)  50  and characteristics of the liquid agent L. 
     The bulk volume of the foam B dispensed per operation is preferably such as fitting in adult&#39;s palm H as illustrated in  FIG. 3A , and may typically be 1 cm 3  or more and 20 cm 3  or less. The amount of dispensed foam B per operation of the foam dispensing container  100  of this embodiment is determined based on parameters including stroke in reciprocating motion of a piston  55  (see  FIG. 4 ) described later. 
     By dispensing a predetermined amount of foam B as a result of operation made on the dispensing operation part (pump head part  32 ) as demonstrated by the foam dispensing container  100  of this embodiment, the foam object FB is prevented from unlimitedly swelling, and thereby a desired foam object FB with intended shape may be built up. A specific geometry of opening of the outlet  20 , in particular the degree of narrowing from the intended shape, is determined so that the desired foam object FB with intended shape will be build up with a total amount of foam B dispensed by repetitively operating the dispensing operation part (pump head part  32 ) a predetermined certain number of times (one or plural times). 
     The geometry of the outlet  20  will further be detailed. 
     As illustrated in  FIG. 2 , the outlet  20  of this embodiment has a linear narrowly-opened part  22  and a widely-opened part  24  made wider than the narrowly-opened part  22 . The widely-opened part  24  is formed contiguously with the narrowly-opened part  22 . The outlet  20  is formed to have a contiguous geometry participated by the narrowly-opened part  22  and the widely-opened part  24 . 
     The linear narrowly-opened part  22  may be a contiguous long opening as described above, or may be discrete openings arranged in line. The narrowly-opened part  22  may have a form of constant-width band, or may have a width that varies in the longitudinal direction. 
     Extension style of the narrowly-opened part  22  may be straight, curved, or bent, without special limitation. The narrowly-opened part  22  in this embodiment is composed of a plurality of narrowly-opened parts  22   a ,  22   b  which are bent and mutually connected. As described later, the narrowly-opened part  22   a  has a straight form, meanwhile the narrowly-opened part  22   b  has a curved form. 
     The widely-opened part  24  is an opened region of the outlet  20 , made wider than the width of opening of the linear narrowly-opened part  22 . Being bounded by a boundary where the width of opening of the outlet  20  discontinuously or abruptly increases, the side with a smaller width of opening will be denoted as the narrowly-opened part  22 , and the wider side will be denoted as the widely-opened part  24 . 
     The widely-opened part  24  may have a line pattern wider than the narrowly-opened part  22 , or may be polygonal or near-circular form, without special limitation. As illustrated in  FIG. 2 , the widely-opened part  24  in this embodiment has a near-circular form with a diameter larger than the width of the narrowly-opened part  22  ( 22   a ,  22   b ). 
     As illustrated in  FIG. 3A , the foam object FB dispensed through the outlet  20  has a wide foam portion WP that corresponds to the widely-opened part  24  and a narrow portion NP that corresponds to the narrowly-opened part  22 . The foam object FB built up by the foam dispensing container  100  of this embodiment has, as schematically illustrated in  FIG. 3B , nearly equal height for the wide foam portion WP and the narrow portion NP. More specifically, as for the container of Patent Literature 1, by which the foam object is composed of discretely dispensed round foams swollen in all directions and crowded each other, it has been necessary to make the volume of each dispensed round foam sufficiently large. In contrast in this embodiment, since the outlet  20  is formed with the contiguous geometry, so that the dispensed foam B swells on the palm H which is the dispensing target plane, solely in the width direction of the outlet  20 , and builds up the foam object FB substantially without expansion in the longitudinal direction. Accordingly, a desired foam object FB with intended shape may be built up only with a small amount of foam B. Owing to the suppressed difference of height within the foam object FB, such desired intended shape will be well-profiled in a plan view. 
       FIG. 4  is a side elevation of the nozzle assembly  50  including the head part  30 .  FIG. 5  is a plan view of the head part  30 .  FIG. 6  is a cross-sectional view taken along line VI-VI in  FIG. 5 , showing a sectional side elevation of the head part  30 .  FIG. 7  is a perspective view of a foam dispenser attachment  10 . 
     As illustrated in  FIG. 4 , the nozzle assembly  50  has, besides the above-described head part  30 , a cap  53 , a housing  56 , a suction tube  57 , and an air-liquid contact portion  51  described later. The housing  56  houses a piston  55 , a spring  58  and a ball valve  59 , and is placed inside the container body  40  (see  FIG. 1 ). The suction tube  57  is provided so as to communicate with the lower part of the housing  56 , being aimed to suck up the liquid agent L. The cap  53  is detachably attached to the bottleneck  44  of the container body  40  while placing the housing  56  and suction tube  57  in the container body  40  (see  FIG. 1 ), to thereby fix the nozzle assembly  50 . 
     More specifically, the foam dispensing container  100  of this embodiment further includes a piston  55  that is attached to the container body  40  by aid of the cap  53  and is movable reciprocatively relative to the cap  53 ; and the housing  56  that houses the piston  55  and communicates with the outlet  20 . The dispensing operation part (pump head part  32 ) in this embodiment sucks the liquid agent L from the container body  40  up into the housing  56  and dispenses it through the head part  30 , by moving the piston  55  reciprocatively upon acceptance of a user&#39;s press-down operation. 
     The structure and operation of the nozzle assembly  50  will be briefed below. The ball valve  59  is a valve that prevents fall of the liquid agent L having been reserved in the housing  56  and the suction tube  57 . When the user presses down, by his or her hand or so, the pump head part  32  (dispensing operation part) of the head part  30 , the piston  55  increases air pressure in the housing  56 , while restricting the ball valve  59  from ascending (opened) with the lower end of the piston  55 . The piston  55  has provided thereto a liquid flow channel (not illustrated), which is a small hole that communicates the housing  56  with the head part  30 . Since the area of opening of the liquid flow channel is sufficiently small, the air pressure in the housing may be elevated by pressing the pump head part  32  down powerfully, and the liquid agent L is then pushed from the housing  56  up into the head part  30 . The head part  30  has provided thereto an air flow channel (not illustrated) that is communicated with the outside. The head part  30  has provided therein an air-liquid contact portion  51  on the flow channel for the liquid agent L. The air-liquid contact portion  51  is typically a mesh, which transforms the liquid agent L into foam (foam B), by allowing the air outside the head part  30  and the air in the housing  56 , together with the liquid agent L, to pass through the air-liquid contact portion  51  (mesh). The foam B is dispensed through the outlet  20  of the head part  30 . When the user releases his or her hand or so from the pump head part  32 , the spring  58  elastically returns the piston  55  to the original position. The pressure inside the housing  56  becomes low, the ball valve  59  is opened, and a new portion of the liquid agent L is sucked up into the suction tube  57  to fill the housing  56  again. The inside of the head part  30  is kept at the atmospheric pressure with the outer air introduced through the air flow channel into the head part  30 . 
     The above-described structure and operation of the nozzle assembly  50  are merely examples, and also well-known ones, such as a foam dispenser described in Patent Literature 4 described above, may be used. 
     With the nozzle assembly  50  of this embodiment, a predetermined amount of foam B is dispensed through the outlet  20 , each time the pump head part  32  (dispensing operation part) is operated. The predetermined amount is determined by parameters such as stroke in reciprocating motion of the piston  55 . 
     As illustrated in  FIG. 4  to  FIG. 6 , the head part  30  of this embodiment is configured to combine a nozzle part  52  and the foam dispenser attachment  10 . The nozzle part  52  has a nozzle opening  54  through which the foamy liquid agent (foam B) from the container body  40  is delivered. The nozzle part  52  is provided above the air-liquid contact portion  51  so as to communicate with the housing  56 , and allows the liquid agent L after transformed into foam to flow therethrough. The nozzle part  52  of this embodiment is integrally formed inside the pump head part  32 . 
     The foam dispenser attachment  10  is used while being detachably attached to the nozzle part  52  of the foam dispensing container  100 . The foam dispenser attachment  10  has the outlet  20 , and when detachably attached to the nozzle part  52 , the outlet  20  communicates with the nozzle opening  54 . More specifically, the foam dispenser attachment  10  of this embodiment has the outlet  20  with the contiguous geometry narrowed from the intended shape, catches the foamy liquid agent (foam B) dispensed from the nozzle opening  54 , and dispenses it through the outlet  20  to build up the foam object FB with intended shape. 
     With such design of the head part  30  separable into the foam dispenser attachment  10  and the nozzle part  52 , a plurality of types of foam dispenser attachments  10  having different opening geometries of the outlet  20  may be attached to the nozzle part  52  in an exchangeable manner. The foam object FB with intended shape may be built up by dispensing, while using the container body  40  and the nozzle assembly  50  in common. Conversely, the common foam dispenser attachment  10  may be attached to the nozzle assemblies  50  of different container bodies  40  in an exchangeable manner. Accordingly, if the container body  40  and the nozzle assembly  50  should be discarded or exchanged, the foam dispenser attachment  10  may be used consecutively, and the foam dispenser attachment  10  may be attached afterward to the container body  40  and the nozzle assembly  50  having widely been put into practical use. 
     As illustrated in  FIG. 6  and  FIG. 7 , the foam dispenser attachment  10  has a fitting part  16  to which the nozzle opening  54  is inserted, and an engagement part  18  that detachably engages with the nozzle part  52 . The fitting part  16  of the foam dispenser attachment  10  is an opening with a geometry corresponded to the outer profile of the nozzle part  52  of the nozzle assembly  50 , and allows the nozzle part  52  to be tightly fitted thereto. Although geometry of the engagement part  18  is not specifically limited, the engagement part  18  in this embodiment is a claw-like projection that projects upward, and is provided in a pair on both sides of the fitting part  16 . As illustrated in  FIG. 2 , the pump head part  32  in this embodiment has an umbrella-like shape, and the circumference  33  of the pump head part  32  suspends downward. The engagement part  18  of the foam dispenser attachment  10  engages with the circumference  33  of the pump head part  32 , particularly on both sides of the nozzle part  52 . In this way, the foam dispenser attachment  10  attached to the pump head part  32  may be prevented from inclining in the front-rear direction and in the crosswise direction relative to the pump head part  32 . The foam dispenser attachment  10  is therefore unlikely to contingently incline or detach, even if the foam B is jetted powerfully through the nozzle part  52  into the foam dispenser attachment  10  by the press-down operation made on the pump head part  32 . 
     As illustrated in  FIG. 6 , the head part  30  has a reservoir  60  that reserves the foamy liquid agent (foam B) delivered from the container body  40 . The reservoir  60  is a void that decelerates the foamy liquid agent (foam B) delivered from the container body  40  through the nozzle part  52 , and feeds the foam B so as to be distributed over the entire portion of the outlet  20 . The reservoir  60  is arranged on the flow channel of the foam B, between the nozzle opening  54  of the nozzle part  52  and the outlet  20 , whose flow channel is made wider than the nozzle opening  54  and the outlet  20 . The reservoir  60  in this embodiment is formed inside the foam dispenser attachment  10  that constitutes the head part  30 , and between the outlet  20  and the fitting part  16 . In this embodiment, the reservoir  60  is provided on the flow channel for the foam B, particularly on the upstream side of the outlet  20  so as to adjoin therewith. The fitting part  16  is provided so as to be opened on the base side (the righthand side in the drawing), of the reservoir  60 . The engagement part  18  is formed so as to project from the base side of the reservoir  60 , and engages with the nozzle part  52  from the lower side thereof. The reservoir  60  has a ceiling  66  that inclines towards the front end side (the lefthand side of the drawing) in the feeding direction of the liquid agent L, and downward towards the outlet  20 . The internal height of the reservoir  60  reduces towards the front end of the feeding direction of the liquid agent (foam B). 
     Since the head part  30  (foam dispenser attachment  10 ), having the outlet  20  opened therein, has the reservoir  60 , the foam B delivered from the container body  40  is temporally reserved in the reservoir  60 , and then uniformly dispensed downward over the entire portion of the outlet  20 . The foam B is therefore prevented from being dispensed predominantly on the front end side (the lefthand side in  FIG. 6 ) of the outlet  20  in the feeding direction of the foam B, but instead dispensed uniformly through the entire portion of the outlet  20 . The foam B delivered from the container body  40  tends to decelerate inside the reservoir  60  particularly on the front end side thereof, and to stagnate therein. In contrast, since the reservoir  60  in this embodiment has the ceiling  66  that declines towards the outlet  20 , so that the foam B that is delivered from the container body  40  and collides on the ceiling  66  turns the direction towards the outlet  20 . In this way, the foam B having been delivered from the container body  40  to the foam dispenser attachment  10 , as a result of press-down operation made on the pump head part  32 , is prevented from excessively stagnating in the front end side of the reservoir  60 , and thus can be smoothly dispensed through the outlet  20 . Owing to that the internal height of the outlet  20  decreases towards the front end side of the feeding direction of foam B, or, towards the distal side away from the nozzle opening  54 , the foam B decelerated inside the reservoir  60  is prevented from stagnating in the front end side of the reservoir  60 . With such design, a uniform amount (predetermined amount) of foam B may be dispensed through the outlet  20  each time the pump head part  32  is pressed down, and thereby reproducibility of the foam object FB built up after dispensed through the outlet  20  will be improved. Although the capacity of the reservoir  60  is not specifically limited, it is preferably smaller than the volume of the foam B dispensed through the nozzle opening  54  when the pump head part  32  is pushed only once (that is, the total volume of the dispensed liquid agent L and the air entrained into the liquid agent L). With such design, the foam B passed through the nozzle opening  54  of the nozzle part  52  is rapidly dispensed through the outlet  20  to give the intended shape, and the volume of the foam B remaining in the head part  30  (foam dispenser attachment  10 ) may be reduced. 
     As described above, the head part  30  of the foam dispensing container  100  has the nozzle part  52 . The nozzle part  52  of this embodiment dispenses the foamy liquid agent (foam B), delivered from the container body  40 , obliquely downward inside the reservoir  60 . The head part  30  (the foam dispenser attachment  10  in this embodiment) has an inclined face  62  that nearly confronts such obliquely downward direction. The inclined face  62  is provided inside the reservoir  60 , and is formed between the wide guide part  28  and the narrow guide part  27 . With such design, the foam B dispensed through the nozzle opening  54  towards the foam dispenser attachment  10  collides on the inclined face  62  to decelerate itself, and is uniformly filled inside the reservoir  60 . The foam B is then dispensed downward through the outlet  20 . The outlet  20  is formed so as to extend between the front end side and the base side of the inclined face  62  (see  FIG. 10 ). In other words, the base side of the foam dispenser attachment  10 , which is in proximity to the fitting part  16 , is a portion where the foam B jetted through the nozzle opening  54  tends to pass the outlet, and is less likely to dispense the foam B as compared with the front end side. Now by forming the inclined face  62  inside the reservoir  62  as in this embodiment to decelerate the foam B, the amount of dispensed foam B may be made uniform over the front end side and the base side of the outlet  20 . 
     The dispensing guide  26  is provided so as to extend downward from the reservoir  60 . The foam B, having been decelerated inside the reservoir  60  and once reserved therein, flows into the dispensing guide  26 , guided downward, and dispensed through the outlet  20 . With the dispensing guide  26  provided below the reservoir  60 , the foam B dispensed through the outlet  20  is reduced to swell. More specifically, the foam B has a lower bulk density and is highly compressive as compared with the liquid agent L in the liquid form, and thereby the foam B delivered through the nozzle opening  54  to the reservoir  60  and reserved there is compressed. For this reason, the foam B largely swells if the length of passage of the dispensing guide  26  is short. In contrast, if the length of passage of the dispensing guide  26  is long, the foam B is gradually depressurized as it passes through the dispensing guide  26 , and is also rectified during passage through the dispensing guide  26 . This advantageously stabilizes the shape of the dispensed foam B, and suppresses the dispensed foam B from swelling, so that the foam object FB with intended shape will be built up in a finely profiled manner. 
     As illustrated in  FIG. 6 , the internal bottom face  64  of the reservoir  60  is made higher in the front end side (internal bottom face  64   b ), than in the base side (internal bottom face  64   a ) of the inclined face  62  (see also  FIG. 8 ). The dispensing guide  26  has the upper end defined by the internal bottom face  64  of the reservoir  60 , and has the lower end defined by the outlet  20 . Accordingly, the height at which the dispensing guide  26  starts (upper end height) is lower than the inclined face  62  on the base side, and higher than the inclined face  62  on the front end side. As illustrated in  FIG. 4 , the outlet  20  is formed so as to lie horizontally at the bottom end of the dispensing guide  26 . The path length of the dispensing guide  26  (vertical length in  FIG. 4  and  FIG. 6 ) is therefore made longer on the front end side (the lefthand side in  FIG. 4 ) of the inclined face  62 , than on the base side (the righthand side in  FIG. 4 ). This properly suppresses the dispensed foam B from swelling after dispensed through the front end side of the outlet  20 . Accordingly, even if the number of times or stroke of the press-down operation made on the pump head part  32  should vary, and thereby the amount of dispensed foam B should vary to some extent, the desired foam object FB with intended shape may be built stably. The outlet  20  of this embodiment is designed to allow a larger amount of foam B to pass through the widely-opened part  24  formed on the front end side of the reservoir  60  as described later. Accordingly, by presetting a longer path length to the dispensing guide  26  corresponding the widely-opened part  24  as described above, it is now possible to equalize the rate of swelling of dispensed foam B having passed respectively through the front end side and the base side of the outlet  20 . 
     The head part  30  may have inside thereof a net body (not illustrated) through which the foamy liquid agent L delivered from the container body  40  is allowed to pass. Although the position of placement of the net body is not specifically limited, it is preferable to place at least a part of the net body inside the dispensing guide  26 , or adjacent to the dispensing guide  26 . In particular, the net body is preferably placed in the vicinity of the outlet  20 . 
     By providing the net body in the vicinity of the outlet  20 , the liquid agent L is prevented from dripping, even if the dispensing direction of foam B should be downward like in this embodiment. More specifically, while the liquid agent L in the state of foam B may otherwise return back to the liquid form with time due to collapse of bubbles, the net body provided close to the outlet  20  will help the liquid agent L in the liquid form adhere thereon, and prevent the liquid agent L from dripping from the outlet  20 . Since the foam B passes through the net body immediately before being dispensed through the outlet  20 , a further fine-bubbled foam may be produced. 
     The net body is a mesh or other porous body. The net body may be a mesh obtained by weaving warps and wefts, made of metal or resin, into plain weave or twilled weave (woven wire net), or may be a perforated screen plate obtained by perforating a sheet-like base to form therein a large number of fine throughholes. Although dimensional relation between the openings of the net body and the aforementioned air-liquid contact portion  51  is not specifically limited, the opening of the net body may be set larger than the opening of the air-liquid contact portion  51 . With such setting, pressure loss at the net body may be reduced, and thereby the pressing force on the pump head part  32 , necessary for dispensing the foam B through the outlet  20 , is prevented from excessively increasing. For the net body and the air-liquid contact portion  51  composed of a plain weave or twilled weave, the opening is determined based on the diameter of the line material and the mesh count (number of line materials per inch). For the net body and the air-liquid contact portion  51  composed of a perforated plate, the opening is determined based on the averaged diameter of the fine throughholes individually approximated to circles. 
     In this embodiment, the net body may be placed on the base side of the feeding direction of the liquid agent L, relative to the outlet  20 . The net body may be placed so as to cover the entire portion of the outlet  20  that is composed of the widely-opened part  24  and the narrowly-opened parts  22   a ,  22   b . A part of the net body may be placed so as to extend over the internal bottom face  64   a  and the inclined face  62  illustrated in  FIG. 6 . Other part of the net body may be positioned inside the dispensing guide  26 , particularly near the lower end thereof adjoining to the outlet  20  (widely-opened part  24 ). Note however that, as an alternative to the above-described embodiment, the net body may be placed so as to cover the widely-opened part  24  only, without placing it over the narrowly-opened parts  22   a ,  22   b . That is, since it is anticipated that dripping of the liquid agent L returned back to liquid would occur particularly at the widely-opened part  24 , so that only the widely-opened part  24  may selectively be covered with the net body. In this way, the foam object FB with intended shape may be built up while avoiding shortage of the foam B to be fed to the narrowly-opened parts  22   a ,  22   b , and while preventing dripping from the outlet  20 . 
       FIG. 8A  is a top perspective view of an upper half  10   a  of the foam dispenser attachment  10 , and  FIG. 8B  is a top perspective view of a lower half  10   b .  FIG. 9  is a bottom perspective view of the upper half  10   a .  FIG. 10  is a plan view of the lower half  10   b.    
     The foam dispenser attachment  10  is configured by mutually combining the upper half  10   a  and the lower half  10   b  in the dispensing direction. The lower half  10   b  has the outlet  20  formed so as to open therein. This configuration facilitates formation of the reservoir  60  that has the inclined face  62  and an inner guide  29  described later, inside the foam dispenser attachment  10 . After the foam dispenser attachment  10  was assembled, the upper half  10   a  and the lower half  10   b  may be joined unseparably, typically by using an adhesive. The upper half  10   a  and the lower half  10   b  may be formed typically by injection molding of a synthetic resin. 
     The outlet  20  has the linear narrowly-opened part  22 , and the widely-opened part  24  that is formed contiguously with the narrowly-opened part  22  and is made wider than the narrowly-opened part  22 . The widely-opened part  24  is placed on the front end side of the inclined face  62 , and the narrowly-opened part  22  is placed on the base side. As illustrated in  FIG. 2 , the dispensing guide  26  has a narrow guide part  27  formed to oppose by sandwiching the narrowly-opened part  22 , and a wide guide part  28  disposed along the widely-opened part  24 . The narrow guide part  27  and the wide guide part  28  communicate with each other while bounded nearly by the width of the narrow guide part  27 . 
     The outlet  20  of this embodiment has a straight narrowly-opened part  22   a  that corresponds to the stem of eighth note, a curved narrowly-opened part  22   b  that corresponds to the flag, and a widely-opened part  24  that corresponds to the head. The dispensing guide  26  is formed so as to surround the circumference of the outlet  20  in a plan view as illustrated in  FIG. 10 . 
     With such design, the foam object FB with intended shape, molded after a musical note (eighth note) as illustrated in  FIG. 3A , may be built up by dispensing. The foam B dispensed through the narrowly-opened parts  22   a ,  22   b  build the narrow portion NP of the foam object FB, meanwhile the foam B dispensed through the widely-opened part  24  builds the wide foam portion WP of the foam object FB. Owing to that the narrow guide part  27  and the wide guide part  28  communicate with each other while bounded nearly by the width of the narrow guide part  27 , the width of the foam object FB abruptly changes at the boundary of the wide foam portion WP and the narrow portion NP. By using the foam dispenser attachment  10  of this embodiment, it is now possible to build up such finely-profiled foam object FB with intended shape by dispensing operation. 
     The widely-opened part  24  is disposed on the front end side (the lefthand side in  FIG. 10 ) of the foam dispenser attachment  10 , and the narrowly-opened parts  22   a  and  22   b  are disposed on the base side (the righthand side in  FIG. 10 ) closer to the fitting part  16 . As described above, since the path length of the dispensing guide on the front end side of the foam dispenser attachment  10  is made longer than the path length of the dispensing guide on the base end side, so that the foam B after passed through the widely-opened part  24  is suppressed from swelling. In this way, the wide foam portion WP of the foam object FB illustrated in  FIG. 3A  is prevented from excessively swelling, so that the foam object FB with the desired intended shape may be built up even if the amount of dispensed foam B should vary to some extent. 
     The plurality of linear narrowly-opened parts  22   a ,  22   b  of the outlet  20  in this embodiment cross each other. As illustrated in  FIG. 10 , the curved narrowly-opened part  22   b  that corresponds to the flag of musical note (eighth note) crosses near the end of the straight narrowly-opened part  22   a  that corresponds to the stem of the note, more specifically crosses at a position slightly set back inwardly from the terminal end. Such intersection will have a relatively large amount of dispensed foam B since the foam B came from the narrowly-opened parts  22   a  and  22   b  will combine there. In this way, as illustrated in  FIG. 3A , the dispensed foam object FB will be built up as if the flag of eighth note is joined to the very end of the stem. 
     As illustrated in  FIG. 8B , on the internal bottom face  64   a  on the base side of the inclined face  62 , inner guides  29   b  are provided so as to extend vertically. The inner guides  29   b  are provided on both sides of the narrow guide part  27 . 
     As illustrated in  FIG. 9 , the upper half  10   a  of the foam dispenser attachment  10  has an inner guide  29   a . The inner guide  29   a  surrounds, in a plan view, at least a part of the circumference of the outlet  20  (see  FIG. 10 ) like a wall. The inner guide  29   a  is formed so as to suspend down from the ceiling  66  of the upper half  10   a . The inner guide  29   a  of the upper half  10   a  and the inner guide  29   b  of the lower half  10   b  (see  FIG. 8B ) are butted to define a compartment of the reservoir  60 , when the upper half  10   a  and the lower half  10   b  are assembled. 
     The inner guide  29   a  of the upper half  10   a  is provided so as to surround a portion of the circumference of the outlet  20 , particularly around the front end side of the feeding direction (indicated by an arrow in  FIG. 9 ) of the liquid agent (foam B) delivered from the container body  40  towards the foam dispenser attachment  10 . The fitting part  16  is provided to the inner guide  29   a , particularly on the base side of the feeding direction of the liquid agent (foam B). 
     The inner guides  29   a  and  29   b  partition the inside of the foam dispenser attachment  10  into the reservoir  60  that communicates with the outlet  20 , and a closed area  61  that does not communicate with the outlet  20 . The fitting part  16  communicates with the reservoir  60  formed on the inner side of the inner guide  29   a . As a consequence, inside the foam dispenser attachment  10 , there are formed the reservoir  60  that constitutes the flow channel of the foam B, and the closed area  61  the foam B cannot enter. With the closed area  61  formed inside the foam dispenser attachment  10 , the volume of reservoir  60  relative to the total volume of foam dispenser attachment  10  is suppressed. It is therefore possible to reduce the amount of foam B that might remain in the reservoir  60  and vanish, rather than dispensed through the outlet  20 . 
     Modified Examples of Foam Dispenser Attachment 
     Modified examples of the foam dispenser attachment  10  of the first embodiment will be explained. 
       FIG. 11A  to  FIG. 14A  are schematic bottom views of foam dispenser attachments  11  to  14  according to a first modified example to a fourth modified example.  FIG. 11B  to  FIG. 14B  are plan views of the foam objects FB respectively dispensed through foam dispenser attachments  11  to  14  of the first modified example to the fourth modified example. 
     As illustrated in  FIG. 11A  and  FIG. 12A , the foam dispenser attachments  11 ,  12  of the first modified example and the second modified example are same as the foam dispenser attachment  10  of the first embodiment (see  FIG. 10 ) in that each of their outlets  20  has the linear narrowly-opened part  22 , and the widely-opened part  24  that is formed contiguously with the narrowly-opened part  22  and is made wider than the narrowly-opened part  22 . It is same as the foam dispenser attachment  10  of the first embodiment also in that each of their widely-opened parts  24  is near circular with the diameter larger than the width of the narrowly-opened part  22 . 
     Meanwhile, the first modified example is different from the first embodiment in the aspects below. That is, as illustrated in  FIG. 11B , at least a part of the intended shape of the foam object FB, built up after dispensed through the foam dispenser attachment  11  of the first modified example, is shaped such that a plurality of near circular portions CP are overlapped in a plan view. The outlet  20  of the first modified example has a plurality of near-circular, widely-opened parts  24  ( 24   a ,  24   b ) that are shrunk from the plurality of near-circular portions CP in the intended shape, and the linear narrowly-opened part  22  that connects these widely-opened parts  24  ( 24   a ,  24   b ). The widely-opened parts  24  ( 24   a ,  24   b ) are portions less likely to be clogged even if the liquid agent L should solidify. With such widely-opened parts  24   a ,  24   b  formed contiguously with the narrowly-opened part  22  on both ends thereof, even if the liquid agent L should solidify to clog the narrowly-opened part  22 , the foam B can still be dispensed through both sides of the clogged portion, so that the solidified component can be kept in contact with the foam B (liquid agent L). As a consequence, the solidified component can be softened or dissolved, entrained by the dispensed foam B, and dispensed through the narrowly-opened part  22 . Clogging is thus avoidable. 
     The foam object FB built up after dispensed through the foam dispenser attachment  11  of the first modified example looks snowman in a plan view. Note that, as a further modified example of the first modified example, the foam object FB may be shaped such that three or more near-circular portions CP are overlapped. In this case, the outlet  20  is preferably composed of three or more near-circular, widely-opened parts  24 , and the linear narrowly-opened parts  22  that mutually connect them. 
     The outlets  20  of the second modified example and the third modified example illustrated in  FIG. 12A  and  FIG. 13A  are same as the first embodiment in that they have a plurality of linear narrowly-opened parts  22  ( 22   a  to  22   c ) that cross each other, but different from the foam dispenser attachment  10  of the first embodiment in that one narrowly-opened part  22   a  branches into, or crossed with, other narrowly-opened part  22   b.    
     The foam object FB built up after dispensed through the foam dispenser attachment  12  of the second modified example looks like human in a plan view. The foam object FB built up after dispensed through the foam dispenser attachment  13  of the third modified example looks like a letter (letter “A” in this modified example) in a plan view. Any one of the narrowly-opened parts  22   a  to  22   c  (the narrowly-opened part  22   b  in this modified example) is divided into a plurality of sections, leaving a separation region  25  in between. In the bottom face  31  of the foam dispenser attachment  13 , an inner region  31   a  surrounded by the narrowly-opened parts  22   a  to  22   c , and an outer region  31   b  around the narrowly-opened parts  22   a  to  22   c  are bridged together by the separation region  25 . The foam dispenser attachment  13  may therefore be molded easily, and the outlet  20  is suppressed from being deformed contingently due to relative displacement of the inner region  31   a  and the outer region  31   b  under dispensing pressure of the foam B. The separation region  25  may be provided to a plurality of points of the narrowly-opened parts  22   a  to  22   c . The length of the separation region  25 , or the divisional distance of the narrowly-opened part  22   b  is preferably short as possible, so as to give the intended shape to the foam object FB, and may typically be made narrower than the line width of the narrowly-opened part  22   b . As an alternative to the embodiment described above, the inner region  31   a  and the outer region  31   b  may be joined with a bridge (not illustrated) provided inside the foam dispenser attachment  13 . With such design, each of the narrowly-opened parts  22   a  to  22   c  may be formed as a contiguous line segment, while disusing the separation region  25 . 
     The outlet  20  of the fourth modified example illustrated in  FIG. 14A  is different from the foam dispenser attachment  10  of the first embodiment, in that it has a series of bent or meandering linear narrowly-opened parts  22   a ,  22   b . Each of the narrowly-opened parts  22   a ,  22   b  has a plurality of line segments  23   a  to  23   c  laid in parallel to each other. The line segments  23   a  to  23   c  are placed in proximity, and the intervals are determined so that the foamy liquid agent (foam B) dispensed through the outlet  20  can swell in the width direction, and then can be crowded to each other to give a planar shape. As illustrated in  FIG. 14B , at least a part of the intended shape of the foam object FB built up after dispensed through the foam dispenser attachment  14  has a planar shape in a plan view. 
     The narrowly-opened parts  22   a ,  22   b  are partial outlets, and jointly constitute the outlet  20 . The narrowly-opened parts  22   a ,  22   b  of the fourth modified example meander like comb teeth, and the end portions are spaced from each other. In other words, the foam dispenser attachment  14  has the separation region  25  between the narrowly-opened parts  22   a ,  22   b  as the partial outlets. The foam B is not dispensed from the separation region  25 , so that the foam object FB will have a vacant portion VC. 
     The foam dispenser attachment  14  of the fourth modified example builds up the planar intended shape, by gathering the foam B respectively dispensed through the line segments  23   a  to  23   c . In other words, when the intended shape of the foam object FB is planar, it is recommendable to virtually divide the plane into a plurality of regions, and to allocate the contiguous partial outlets of the outlet  20 , each of which being narrowed from each region. With such design, the foam object FB having a large area or a complicated shape may accurately be built up with the foam B. 
     In conclusion, as represented by the foam dispenser attachments  10  to  14  of the first embodiment, and of the first to fourth modified examples, the outlet  20  used in this invention may have a variety of opening geometries. 
     Second Embodiment 
       FIG. 15  is an explanatory drawing illustrating a structure of the foam dispensing container  110  of a second embodiment. 
     The foam dispensing container  110  of the second embodiment is different from the foam dispensing container  100  of the first embodiment (see  FIG. 1 ), in that it dispenses the foam B while being electrically actuated. The foam dispensing container  110  of this embodiment has a power source unit  90 , a pump mechanism  92  that is powered by the power source unit  90  and delivers the liquid agent L from the container body  40 , and a control unit  95  that controls operation of the pump mechanism  92 . The dispensing operation part of the second embodiment includes a sensing part  96  that senses approach or input operation of the user. The control unit  95  activates a motor  98  and the pump mechanism  92  upon detecting the approach or input operation of the user by the sensing part  96 , and makes them dispense the predetermined amount of foamy liquid agent (foam B) through the outlet  20 . 
     The foam dispensing container  110  of the second embodiment is different from the foam dispenser attachment  10  of the first embodiment (see  FIG. 1 ), in that the foam dispenser attachment  10  is attached to an enclosure  99  permanently, rather than detachably. According to the foam dispensing container  110  of the second embodiment, the foam dispenser attachment  10  is disposed inside the enclosure  99 , with the outlet  20  exposed from the enclosure  99 . 
     The pump mechanism  92  has a reservoir  91 , a piston  93   a , a plunger  93   b  and a check valve  93   c . The container body  40  with the liquid agent L reserved therein is set upside down in the enclosure  99  while directing the bottleneck downward. The reservoir  91  accepts the liquid agent L from the container body  40 . The piston  93   a  is actuated by the motor  98 , and reciprocally drives the plunger  93   b  to close the flow channel of the reservoir  91  in a freely openable/closable manner. The check valve  93   c  allows the liquid agent L to flow unidirectionally from the reservoir  91  towards the foam dispenser attachment  10 , while preventing backflow. 
     The motor  98  is powered by the power source unit  90 , and the operation thereof is controlled by the control unit  95 . As the power source unit  90 , a dry cell is typically used. The sensing part  96  is a proximity sensor that is disposed near the outlet  20  of the foam dispenser attachment  10 , and detects approach of the user&#39;s hand. The sensing part  96  is typically a reflective sensor having an infrared transceiver. When the sensing part  96  detects approach of the user&#39;s hand, a detection signal is sent to the control unit  95  and used for activating the motor  98 . 
     In the middle of a tube path  94   a  that constitutes the flow channel of liquid agent L, connecting the reservoir  91  and the foam dispenser attachment  10 , there is provided an air-liquid contact portion  94   b . When the piston  93   a  is positioned at the top dead center as illustrated in  FIG. 15 , the inlet of the reservoir  91  is closed with the plunger  93   b  to inhibit traffic of the liquid agent L between the container body  40  and the reservoir  91 . The motor  98  rotates a cam (not illustrated) to reciprocate the piston  93   a . As the piston  93   a  descends, the inlet of the reservoir  91  is released, the liquid agent L enters the reservoir  91 , and the plunger  93   b  pushes the liquid agent L towards the foam dispenser attachment  10 . The pushed liquid agent L is transformed into foam in the air-liquid contact portion  94   b , delivered to the foam dispenser attachment  10 , and dispensed through the outlet  20  to build up the foam object FB with intended shape (see  FIG. 3 ). 
     Upon receiving a detection signal from the sensing part  96 , the control unit  95  activate the motor  98  so as to reciprocate the piston  93   a  a preset number of times. In this way, a predetermined amount of liquid agent L is dispensed as the foam B through the outlet  20 . 
     As seen in the foam dispensing container  110  of the second embodiment, the foam dispenser attachment  10  may be used while attached to the enclosure  99 . Alternatively, as seen in the foam dispensing container  100  of the first embodiment (see  FIG. 1 ), the foam dispenser attachment  10  may be used while detachably attached to the pump head part  32 . 
     Third Embodiment 
       FIG. 16  is a top perspective view of the foam dispensing container  100  according to a third embodiment of this invention, and  FIG. 17  is a bottom perspective view of the foam dispensing container  100 .  FIG. 18A  is a plan view of the foam object FB dispensed through the foam dispensing container  100  of this embodiment, and  FIG. 18B  is a front elevation of the foam object FB.  FIG. 19  is a front elevation of the foam delivery mechanism  50  including the head part  30 . 
     The foam dispensing container  100  of the third embodiment is different from the first embodiment in that it has an extension part  70 , leaving the other aspects in common. 
     More specifically, the foam dispensing container  100  of the third embodiment has the container body  40  that reserves the liquid agent L; and the head part  30  that has the outlet  20 , and dispenses the liquid agent L delivered from the container body  40  through the outlet  20  into foam. The head part  30  has the dispensing operation part (pump head part  32 ). The dispensing operation part (pump head part  32 ) dispenses a predetermined amount of foamy liquid agent (foam B) through the outlet  20 , each time the user&#39;s operation is accepted. The dispensed foam B is schematically illustrated in  FIG. 16  and  FIG. 17  with a two dot chain line. The foamy liquid agent (foam B) dispensed through the outlet  20  in the predetermined dispensing direction DD, after one-time or plural times of operations made on the dispensing operation part (pump head part  32 ), is built up into the desired foam object FB with intended shape as illustrated in  FIG. 18A . 
     The head part  30  of this embodiment has extension parts  70  that extend beyond the front end position of the outlet  20  with respect to the dispensing direction DD. 
     Since the extension parts  70  extend beyond the front end position of the outlet  20  with respect to the dispensing direction DD, the extension parts  70  may be brought into contact with the dispensing target plane TP, while opposing the outlet  20  to the dispensing target plane TP leaving a space in between. In this way, the distance SP (see  FIG. 21 ) between the outlet  20  and the dispensing target plane TP may be kept at a desired level. More specifically, the extension parts  70 , when used by bringing the tips (lower ends) into contact with the dispensing target plane TP, can serve as a spacer between the outlet  20  and the dispensing target plane TP. With such spacer function given to the foam dispensing container  100 , conditions for dispensing the foam B through the outlet  20  may be stabilized among the users and the operations. With the outlet  20  whose geometry is preliminarily determined so that the foam object FB with intended shape may be built up on the dispensing target plane TP placed such distance SP away from the outlet  20 , it now becomes possible to build up the desired foam object FB with the foam B dispensed upon operations made on the dispensing operation part, in a highly reproducible manner. The extension parts  70  not only function as the spacer as described above, but are also used as described later in a fifth embodiment as a shaping member that adds a pointed part P to the foam object FB (see  FIGS. 26A and 26B ). More specifically, by placing the extension part  70  so that it can contact with the foam B dispensed through the outlet  20  onto the dispensing target plane TP, the extension part  70  may be used as the shaping member. The extension part  70 , intended to be used as the shaping member, may be used in contact with the dispensing target plane TP, or may be used while slightly lifted up above the dispensing target plane TP. 
     Now the phrase stating that “the dispensed foamy liquid agent (foam B) is built up into the foam object FB with intended shape” means that the foam B dispensed through the outlet  20  is made up into the predetermined shape on the dispensing target plane TP. The intended shape of the foam object FB is not specifically limited, and is exemplified by geometrical shapes, characters&#39; shapes and so forth. The intended shape means at least one of plan view geometry of the foam object FB when seen confronting to the dispensing target plane TP, or a three dimensional steric shape of the foam object FB. The foam object FB with intended shape includes foam objects shaped differently from those dispensed through a single nozzle with a circular cross section having widely been used in public in the foam dispensing container. Such foam objects include those built up after dispensed through a plurality of outlets, and those built up after dispensed through one or plural outlets that are formed by combining circle, rectangle and so forth. 
     This embodiment exemplifies a foam pump bottle designed to mechanically dispense the liquid agent L from the container body  40 , when the pump head part  32  is pressed down. In the foam dispensing container  100  of this embodiment, the piston  55  (see  FIG. 19 ) is driven as described later upon press-down operation made on the pump head part  32 , and the liquid agent L having been reserved under normal pressure in the container body  40  is sucked up through the suction tube  57 . A seventh embodiment described later exemplifies an electrically driven dispenser that is electrically actuated to dispense the liquid agent L (see  FIG. 28 ). Roughly speaking, the foam dispensing container  100  is composed of the container body  40  that reserves the liquid agent L, and the foam delivery mechanism  50  that is attached to the container body  40  to dispense the liquid agent L. 
     The head part  30  of this embodiment is configured by detachably combining the pump head part  32  having the nozzle part  52 , and the foam dispenser attachment  10  having the outlet  20  (see  FIG. 21 ). Note that, alternatively to this embodiment, the head part  30  may be configured by the outlet  20  and the pump head part  32  that are formed in an integrated manner. With such design, the outlet  20  is prevented from wobbling, and thereby the distance SP between the outlet  20  and the dispensing target plane TP (see  FIG. 21 ), when the pump head part  32  is pressed down with the extension parts  70  kept pressed against the dispensing target plane TP, is prevented from varying contingently. 
     The outlet  20  is formed so as to be opened downward in a bottom face  31  of the head part  30 , at a position (on the distal side) laterally projected out from the bottleneck  44  of the container body  40 . The dispensing direction DD of the foam B dispensed through the outlet  20  of this embodiment is downward, so that a downward view will now be referred to as a plan view. The foam B dispensed through the outlet  20  and exposed to the air descends towards the dispensing target plane TP (see  FIGS. 18, 21 ), while being modeled after the outlet  20  as a whole, but locally swells in the individual portions to build up the foam object FB. The foam object FB may be built on the dispensing target plane TP after fallen from the outlet  20  and downwardly away from the outlet  20 , or may be built so as to fill the space between the outlet  20  and the dispensing target plane TP. For the latter case, the level of height of the top face of the foam object FB is preferably equal to or higher than the outlet  20 , and lower than the bottom face  31  of the head part  30 , from the viewpoint of stably building up the foam object FB into the desired intended shape. 
     The dispensing target plane TP is a flat plane or a curved plane on which the foam object FB is built up. Although a user&#39;s palm is exemplified in  FIG. 18A , this is also exemplified by surfaces of various application tools such as sponge, brush and so forth. For pointed bristles of brush, a flat plane or curved plane given by a set of pointed bristles will be referred to as the dispensing target plane TP. 
     Now the dispensing direction DD of the foam B means an overall direction of the foam B dispensed through the outlet  20 . The dispensing direction DD is determined by various factors. The factors include flow direction of the foam B that passes through the outlet  20 , an angle formed between the flow direction and the direction the outlet  20  opens, an angle between the direction of gravity and the direction the outlet  20  opens, and rate of swelling of the foam B that swells after dispensed through the outlet  20  and exposed to the air. 
     The head part  30  has the extension parts  70  that extend beyond the front end position of the outlet  20  with respect to the dispensing direction DD. The “front end position of the outlet  20  with respect to the dispensing direction DD” means the frontmost position, in the dispensing direction DD, of the circumferential wall (inner circumferential face of the dispensing guide  26 ) that partitions the outlet  20 . The inner circumferential face of the dispensing guide  26  is the wall with which the foam B dispensed through the outlet  20  comes into contact. 
     The normal line of the outlet  20  of this embodiment (downward in  FIG. 19 ) agrees with the dispensing direction DD, and the front end position of the outlet  20  with respect to the dispensing direction DD is kept at constant over the entire portion of the outlet  20 . The normal line of the outlet  20  and the dispensing direction DD can agree also for the case where both of them are directed obliquely downward or laterally, besides the case of this embodiment where both are directed downward. 
     For the case, as an alternative to this embodiment, where the normal line of the outlet  20  crosses the dispensing direction DD, the front end position of the outlet  20  in the dispensing direction DD is given by the frontmost point, in the dispensing direction DD, of the circumferential wall that partitions the outlet  20 . The cases where the normal line of the outlet  20  crosses the dispensing direction DD include, for example, the case where the outlet  20  was formed by beveling the tip of the tubular dispensing guide  26  (see  FIG. 19 ) like an injection needle, or the case where the outlet  20  is formed to have curved face. 
     The phrase stating that the “extension parts  70  extend beyond the front end position of the outlet  20  with respect to the dispensing direction DD” means that at least a part of the extension parts  70  is positioned ahead of the front end position of the outlet  20  with respect to the dispensing direction DD. The extension parts  70  of this embodiment are formed so as to extend, relative to the outlet  20 , from the rear side to the front side in the dispensing direction DD. At least the front ends  74  of the extension parts  70  are positioned below the outlet  20 , and in other words, positioned ahead in the dispensing direction DD beyond the front end position of the outlet  20 . 
     The extension parts  70  in this embodiment are fixed in terms of positional relation relative to the outlet  20 . With such design, the extension parts  70  are prevented from moving relative to the outlet  20  even when pressed against the dispensing target plane TP, and can keep the distance SP (see  FIG. 21 ) between the outlet  20  and the dispensing target plane TP at a desired level. 
     The extension parts  70  in this embodiment, illustrated in  FIG. 19 , are arranged outside the inner circumferential face of the dispensing guide  26 , so that the foam B dispensed through the outlet  20  falls down on the dispensing target plane TP without making contact with the extension parts  70 . The extension parts  70  may be formed integrally with the outer circumferential face of the dispensing guide  26 , or may be formed separately from the dispensing guide  26 . The extension parts  70  in this embodiment are formed separately from the dispensing guide  26 , outside in the width direction of the dispensing guide  26  and away therefrom. 
     As illustrated in  FIG. 17 , the outlet  20  is formed so as to be opened at the bottom end of the dispensing guide  26  provided to the lower portion of the head part  30  (more specifically, the reservoir  60 : see  FIG. 21 ). The dispensing guide  26  is provided so as to suspend down from the bottom face  31  of the head part  30 , and so as to surround the circumference of the outlet  20  like a wall. This prevents the foam B from adhering to the undersurface of the head part  30 , making the foam B more releasable, and making it possible to build up a finely-profiled foam object FB. Note, however, that this invention is not limited thereto, wherein the dispensing guide  26  may be buried in the wall of the bottom face  31  of the head part  30 . For example, the bottom face  31  may be made thick, and a through-hole formed so as to extend through the bottom face  31  may be used as the dispensing guide  26 . 
     The normal line of the outlet  20  (opening) lies parallel to the direction the dispensing guide  26  suspends down. The dispensing direction DD in the foam dispensing container  100  of this embodiment therefore lies in the direction of normal line of the outlet  20  (opening), which directs downward as indicated by an arrow in  FIG. 17 . 
     As illustrated in  FIG. 17 , the extension parts  70  in this embodiment are provided outside the region where the foamy liquid agent (foam B) dispensed through the outlet  20  passes. In  FIG. 18A , footing regions FP of the palm, as the dispensing target plane TP, where the front ends  74  of the extension parts  70  are brought into contact are indicated by two dot chain lines. The footing regions FP are located outside the building region of the foam object FB, and the extension parts  70  are located outside the building region of the foam object FB with intended shape. Now the “front ends  74  of the extension parts  70 ” mean the lower end faces of the extension parts  70 . By making the extension parts  70  flattened on the front ends  74  thereof, the extension parts  70  may be brought into contact stably with the dispensing target plane TP. The front ends  74  of the extension parts  70  may however be given curved faces that are slightly rounded, in consideration of gentle touch on the user&#39;s palm. 
     The front ends  74  of the extension parts  70  are formed within a region that may be encompassed within the palm of one hand of the user (at least adult male). Positions of the base portions and front ends of the extension parts  70  may be determined depending on geometry or size of the outlet  20 . 
     The extension parts  70  are preferably provided at a plurality of discrete positions around the outlet  20 . More preferably, a pair of extension parts  70  are opposingly formed on both sides of the outlet  20 , and so as to project out from the circumferential face of the foam dispenser attachment  10 . 
     The extension parts  70  of this embodiment are integrally formed with the foam dispenser attachment  10  using a single material. With this design, the extension parts  70  will not be detached from the foam dispenser attachment  10 , even when the extension parts  70  are kept pressed against the dispensing target plane TP and applied with drag from the target plane TP as a result of press-down operation made on the pump head part  32 . However, as a modified example of this embodiment, the extension parts  70  may be detachably attached to the foam dispenser attachment  10 . In other words, the extension parts  70  may have a detachable engagement part adapted to the foam dispenser attachment  10 . The detachable engagement part is exemplified by a claw part that grasps the foam dispenser attachment  10 , and an adhesive tape used for adhesive fixation to the foam dispenser attachment  10 . With the extension parts  70  made detachable from the head part  30 , whether the foam dispenser attachment  10  should have a function of spacer or shaping member attributable to the extension parts  70 , or not, is now a matter of choice. Alternatively, the existing foam dispenser attachment will have a function of spacer or shaping member, by attaching the extension parts  70  as add-ons. 
     As illustrate in  FIG. 19 , the extension parts  70  are formed so as to diverge as they depart from the outlet  20  with respect to the dispensing direction DD (downward in this drawing). The pair of extension parts  70  of this embodiment are preferably formed so as to project out from the circumferential face of the foam dispenser attachment  10 , and to suspend down diagonally while being curved. More preferably, bottom end parts  72  of the extension parts  70  rise more steeply than top end parts  71 . In other words, the pair of extension parts  70  are formed so as to abruptly expand the opposing distance between the top end parts  71 , and so as to rise almost normally to the horizontal plane (dispensing target plane TP: see  FIG. 21 ) at the bottom end parts  72 . With such design, the foam B is prevented from contacting with, and adhering to the top end parts  71 , even if the foam B dispensed through the outlet  20 , upon being exposed to the air, should swell right under the outlet  20 . The foam object FB, when built up on the dispensing target plane TP, is also prevented from contacting with the bottom end parts  72 . The foam object FB can therefore be formed into the desired intended shape in a stable manner. 
     It suffices that the front ends of the extension part  70  of the this embodiment, when viewed from the front of the dispensing direction DD confronting to the outlet  20 , reside outside the closed area that surrounds the outlet  20 , and the position thereof is not specifically limited. The pair of extension parts  70  of this embodiment are formed outside the outlet  20 , and on both sides thereof away from each other in the width direction (the lateral direction in  FIG. 19 ) that crosses the distal-proximal direction connecting the container body  40  and the outlet  20 . An intermediate part  78  (see  FIG. 16 ) that resides between the pair of extension parts  70  and on the distal side (on the front side of the sheet of  FIG. 19 ) of the outlet  20  is opened wider than the width of formation W of the outlet  20 . With such design, after the foam object FB with intended shape was built on the dispensing target plane TP, the dispensing target plane TP (palm) may easily be brought away from the foam dispenser attachment  10  without letting the extension parts  70  contact the thus built foam object FB. More specifically, it is recommendable to elevate the pressed-down foam dispenser attachment  10  from the dispensing target plane TP so as to take the extension parts  70  away from the dispensing target plane TP, and then to take out the foam object FB from under the foam dispenser attachment  10  through or just under the intermediate part  78  where the extension parts  70  are not formed. Alternatively, it is also recommendable to, before the pressed-down foam dispenser attachment  10  is elevated, the dispensing target plane TP is brought down relative to the foam dispenser attachment  10  to take the extension parts  70  away from the dispensing target plane TP, and then to take out the foam object FB together with the dispensing target plane TP. In these ways, the foam object FB is prevented from being deformed due to contact with the extension parts  70 . When dispensing the foam B, the space between the dispensing target plane TP and the foam dispenser attachment  10  can be seen through the intermediate portion  78  that is kept open without the extension parts  70  formed therein. With such design, the user can visually observe that a sufficient amount of foam B is dispensed on the dispensing target plane TP to build up the foam object FB. 
     The outlet  20  of this embodiment has the shape identical to that of the first embodiment, and is composed of an opening that has the contiguous geometry narrowed from the intended shape of the foam object FB. As an alternative to this embodiment, the outlet  20  may be composed of a plurality of discretely arranged openings, in the same way as in the foam dispenser attachment  13  described later in a sixth embodiment. 
     The linear narrowly-opened part  22  may be a contiguous long opening as described above, or may be composed of discrete openings arranged in line. With intervals of such discreteness adjusted to a predetermined value or below, the foams B dispensed through such plurality of openings arranged in line will be crowded together on the dispensing target plane TP to build up the a contiguous linear foam object FB. 
       FIG. 20  is a plan view of the head part  30 .  FIG. 21  is a cross-sectional view taken along line VI-VI in  FIG. 20 , and is a sectional side elevation of the head part  30 .  FIG. 22  is a perspective view of the foam dispenser attachment  10 .  FIG. 23A  is a top perspective view of the upper half  10   a  of the foam dispenser attachment  10 , and  FIG. 23B  is a top perspective view of the lower half  10   b.    
     As illustrated in  FIG. 19  to  FIG. 21 , the head part  30  of this embodiment is configured by combining the nozzle part  52  (see  FIG. 21 ) and the foam dispenser attachment  10 . 
     The foam dispenser attachment  10  accepts the foamy liquid agent (foam B) dispensed through the nozzle opening  54 , and dispenses it through the outlet  20  in the predetermined dispensing direction DD, to thereby build up the foam object FB with intended shape. The foam dispenser attachment  10  of this embodiment has the above-described extension parts  70  that extend beyond the front end position of the outlet  20  with respect to the dispensing direction DD. 
     As illustrated in  FIG. 21  and  FIG. 22 , the foam dispenser attachment  10  has the fitting part  16  to which the nozzle opening  54  (see  FIG. 22 ) is inserted, and the engagement part  18  that detachably engages with the nozzle part  52  (see  FIG. 21 ). As illustrated in  FIG. 17 , the pump head part  32  of this embodiment has an umbrella-like shape, and the circumference  33  of the pump head part  32  suspends downward. The engagement part  18  of the foam dispenser attachment  10  engages with the circumference  33  of the pump head part  32  particularly on both sides of the nozzle part  52 . With such design, the foam dispenser attachment  10  attached to the pump head part  32  is prevented from inclining back and forth, or left and right relative to the pump head part  32 . The foam dispenser attachment  10  will therefore not incline or come off contingently, even when the pump head part  32  was pressed down while keeping the front ends  74  of the extension parts  70  pressed against the dispensing target plane TP. 
     &lt;Method of Producing Foam Object&gt; 
     Next, a method of producing a foam object (occasionally referred to as “the present method”, hereinafter) according to an embodiment of this invention will be explained. 
     The present method relates to a method by which the foam B is dispensed from the foam dispensing container  100  (see  FIG. 17 ) to build up the foam object FB (see  FIG. 18A  and  FIG. 18B ). The foam object FB is built on the dispensing target plane TP. The foam dispensing container  100  is a foam pump bottle, and has, as described above, the container body  40  that reserves the liquid agent L, and the head part  30  that dispenses the liquid agent L delivered from the container body  40  through the outlet  20  into foam by predetermined portions, each time the user&#39;s press-down operation is accepted. The head part  30  has the pump head part  32  that accepts the user&#39;s press-down operation. 
     The present method includes an arrangement step and a dispensing step. In the arrangement step, the dispensing target plane TP is opposed to the outlet while keeping a predetermined distance SP in between. In the dispensing step, the foamy liquid agent (foam B) is dispensed through the outlet  20  onto the dispensing target plane TP so as to build up a foam object FB with intended shape, by pressing down the head part  30  and by concurrently lowering the dispensing target plane TP while keeping the predetermined distance SP in between. 
     With such design, since the foam B is dispensed through the outlet  20  while keeping a predetermined distance SP between the outlet  20  and the dispensing target plane TP, so that the state of foam B after dispensed and reaches the dispensing target plane TP will be reproducible, and the foam object FB with the desired intended shape may be built up repetitively. 
     The foam B dispensed through the outlet  20  has a small shape retention, and may swell upon being exposed to the air, or can be rounded up into ball shape. The shape of the resultant foam object FB can therefore easily vary, just by changing the distance between the outlet  20  and the dispensing target plane TP such as user&#39;s palm. In contrast, according to the foam dispensing container  100 , the foam dispenser attachment  10 , and the method of producing a foam object of this embodiment, the foam object FB that is built up on the dispensing target plane TP upon each dispensing operation made by the user will enjoy an improved reproducibility of shape. Thus the foam object FB may be built up into the desired intended shape in a highly accurate manner. 
     The present method may also perform a elevation step in which the pressed-down head part  30  and the lowered dispensing target plane TP are elevated while keeping the distance SP in between, and a dispensing step again. Since the distance between the dispensing target plane TP and the outlet  20  is kept constant over the elevation step and the plural times of dispensing steps, so that the desired foam object FB with intended shape may be built up with the foams B dispensed in the plural times of dispensing steps in a highly reproducible manner. At least the arrangement step of the present method is preferably carried out while mutually joining the head part  30  and the dispensing target plane TP (see  FIG. 21 ). Preferably, in the arrangement step and the dispensing step, the head part  30  and the dispensing target plane TP are joined to each other. In this way, in the dispensing step, the head part  30  and the dispensing target plane TP may easily be brought down in an interlocked manner, so that the distance SP between the outlet  20  and the dispensing target plane TP may be kept constant easily. 
     As described above, the head part  30  has the extension parts  70  that extend beyond the front end position of the outlet  20 , with respect to the dispensing direction DD the foamy liquid agent (foam B) is dispensed through the outlet  20 . In the arrangement step and the dispensing step, by pressing the front ends  74  of the extension parts  70  against the dispensing target plane TP so as to mutually join the head part  30  and the dispensing target plane TP, the outlet  20  and the dispensing target plane TP are kept at a predetermined distance SP (see  FIG. 21 ). In this way, the distance SP may be kept stably during the press-down operation made on the head part  30 . Although mode of joining of the head part  30  and the dispensing target plane TP is not specifically limited, the front ends  74  of the extension parts  70  may be brought into contact with the surface of the dispensing target plane TP as in the present method. Alternatively, the dispensing target plane TP may be held by the extension parts  70 , or still alternatively, the extension parts  70  and the dispensing target plane TP may be detachably engaged. 
     In one modified example of the present method, it is recommendable for the user, in the arrangement step and the dispensing step, to bring his or her fingers of one palm, which is the dispensing target plane TP, into contact with the head part  30 , typically in such a way that he or she bends its fingers of one palm upward to hold the head part  30 . In this way, the head part  30  and the dispensing target plane TP are linked by aid of the fingers in the arrangement step and the dispensing step, and thereby the outlet  20  and the palm (dispensing target plane TP) may be kept at the predetermined distance SP. 
     Now other embodiments of the foam dispensing container and the foam dispenser attachment of this invention will be explained. Descriptions that overlap those in the third embodiment will be skipped properly. 
     Fourth Embodiment 
       FIG. 24A  is a bottom perspective view of a foam dispenser attachment  11  according to a fourth embodiment, and  FIG. 24B  is a cross-sectional view taken along line X-X in  FIG. 24A . The foam dispenser attachment  11  of the fourth embodiment is different from the foam dispenser attachment  10  of the third embodiment in that the extension part  70  is circumferentially provided so as to surround the outlet  20 . 
     The foam dispenser attachment  11  of the fourth embodiment is in common with the foam dispenser attachment  10  of the third embodiment in that the extension part  70  is provided outside the region where the liquid agent (foam B) passes through, and the region where the foam object FB with intended shape (see  FIG. 18A  and  FIG. 18B ) is built up. The fourth embodiment and the third embodiment are same also in that the extension part  70  is formed so as to diverge as it departs from the outlet  20  in the dispensing direction DD. 
     The extension part  70  of this embodiment has a form of partially-sphered cylinder (that is, “dome”), with the top and bottom ends opened. The foam dispenser attachment  11  of this embodiment is same as the foam dispenser attachment  10  of the third embodiment (see  FIG. 19 ) in that, as illustrated in  FIG. 24B , the bottom end part  72  of the extension part  70  rises more steeply than the top end part  71 . 
     The aperture of the opening of the top end part  71  of the extension part  70  can totally contain the dispensing guide  26  both in terms of geometry and size, leaving a void V formed between the whole circumference of the dispensing guide  26  and the extension part  70 . The aperture of the bottom end part  72  of the extension part  70  can totally contain the intended shape of the foam object FB to be built up (see  FIG. 18A  and  FIG. 18B ), and is larger than the intended shape. 
     With the extension part  70  circumferentially formed as in the fourth embodiment, contact between the dispensing target plane TP (see  FIG. 18A  and  FIG. 18B ) and the extension part  70  is stabilized, and thereby the dispensing target plane TP can be confronted accurately to the outlet  20  without being inclined. 
     Geometry of the circumferential go-around-type extension part  70  is not specifically limited. Although in this embodiment it is given as the partially spherical shape that diverges downward, the shape is not limited thereto. The extension part  70  may have a form of truncated cone, or may have a shape widened or thickened from the geometry of aperture of the outlet  20 , or from the dispensing guide  26 . The bottom end of the extension part  70  may be circular as shown in this embodiment, or may alternatively have a shape other than circle, such as a rectangular shape, and may have a shape thickened from the geometry of aperture of the outlet  20 . 
     Alternatively, the go-around-type extension part  70  may be made translucent or semi-translucent, entirely or partially. Still alternatively, the extension part  70  may have a peephole provided to a part thereof, or may have a notch at the bottom end thereof. With such design, how the foam object FB was built up may be visually confirmed, before the foam object FB built on the dispensing target plane TP is taken out from the extension part  70 . 
     Fifth Embodiment 
       FIG. 25A  is a bottom perspective view of a foam dispenser attachment  12  according to a fifth embodiment.  FIG. 25B  is a side elevation of the foam dispenser attachment  12 , and  FIG. 25  is a bottom view.  FIG. 26A  is a plan view of the foam object FB dispensed through the foam dispenser attachment  12  of the fifth embodiment, and  FIG. 26B  is a perspective view of the foam object FB. 
     The foam dispenser attachment  12  of the fifth embodiment is different from the foam dispenser attachment  10  of the third embodiment in that at least the front end part  74  of the extension part  70  is provided within the area where the foam object FB with intended shape is built. In other words, the extension part  70  of this embodiment is preferably brought into contact with the foam B dispensed through the outlet  20 . 
     The extension part  70  of the fifth embodiment is provided, as illustrated in  FIG. 25C , inside the outlet  20  in a plan view in the dispensing direction DD. A part of the foam B dispensed through the outlet  20  therefore streams on the surface of the extension part  70  down onto the dispensing target plane TP. 
     With such design, when the extension part  70  is drawn out from the built foam object FB, a part of the foam B is dragged up by the extension part  70  while adhering thereto, to produce a pointed part P on the surface of the foam object FB. Accordingly, for an exemplary case as illustrated in  FIGS. 26A and 26B  where the foam object FB is built up into a shape of animal (rabbit) or other characters, it is now possible to make a projection that represents a nose or so on the foam object FB. In other words, the extension part  70  may be used as a shaping member for creating a three-dimensional portion onto the foam object FB. The extension part  70  of this embodiment is formed inside the inner circumferential face of the dispensing guide  26  with which the foam B dispensed through the outlet  20  comes into contact. The extension part  70  may be formed integrally with the inner circumferential face of the dispensing guide  26 , or may be formed separately from the dispensing guide  26 . The extension part  70  of this embodiment is arranged at a position inwardly away from the inner circumferential face of the dispensing guide  26 , and separately from the dispensing guide  26 . With such design, when the projection is formed on the foam object FB by dragging up a part of the foam B adhered to the extension part  70 , it is now possible to prevent the contour of the foam object FB from being deformed by the extension part  70 . 
     The extension part  70  of this embodiment may be used as a spacer for keeping the distance SP between the outlet  20  and the dispensing target plane TP (see  FIG. 21 ) to a predetermined value, while bringing the front end part  74  thereof into contact with the dispensing target plane TP. In this way, the extension part  70  of this embodiment can serve both as the shaping member and the spacer. 
     Alternatively, the foam B may be dispensed while keeping the front end part  74  of the extension part  70  slightly lifted above the dispensing target plane TP, and thus arranged in a contactless manner. In this case, the extension part  70  is not used as the spacer, but may be used solely as the shaping member for creating the pointed part P on the foam object FB. 
     The extension part  70  of this embodiment has a pillar form as a whole, and is provided in parallel to the dispensing direction DD, so as to project out from the ceiling  66  of the reservoir  60  of the foam dispenser attachment  10  (see  FIG. 21 ). The extension part  70  of this embodiment has the front end part  74 , and a rod-like stem part  76  with a diameter shrunk from the front end part  74 . With such design, it is now possible to moderate pressure applied to the dispensing target plane TP through the extension part  70 , when the front end part  74  is brought into contact with the dispensing target plane TP (see  FIG. 18 ). Since the dispensed foam can contact well with the thick front end part  74 , so that the pointed part P may be created with a sufficient amount of foam B, by lifting up the extension part  70  and the foam dispenser attachment  10  from the dispensing target plane TP. 
     Although the front end part  74  in this embodiment appears spherical, this invention is not limited thereto. The bottom face of the front end part  74  may be formed flat. With such design, the front end part  74  can contact by surface with the dispensing target plane TP, so that the dispensing target plane TP may be confronted stably to the outlet  20 . The shape of the front end part  74  is not limited to sphere, but may have various shapes depending on the geometry and size of the pointed part P to be formed on the foam object FB. 
     The outlet  20  has the linear narrowly-opened part  22 , and the widely-opened part  24  that is formed contiguously with the narrowly-opened part  22  and is made wider than the narrowly-opened part  22 . The foam B dispensed through the widely-opened part  24  composes a near-circular part CP of the foam object FB, and the foam B dispensed through the narrowly-opened part  22  composes a narrow portion NP of the foam object FB. The extension part  70  is provided within the widely-opened part  24 . The stem part  76  of the extension part  70  of this embodiment is vertically arranged nearly at the center of the widely-opened part  24 . The extension part  70  can therefore come into contact with the foam object FB nearly at the center of the near-circular part CP, so that the near-circular part CP and the narrow portion NP will not be disturbed in their contours, and the foam object FB is suppressed from being deformed as a whole. 
     Although a character shape exemplified in the fifth embodiment as the intended shape of the foam object FB was a head of rabbit having two narrow portions NP projected out from the near-circular portion CP, this is merely an instance. For example, in one modified example of the fifth embodiment, at least a part of the intended shape may be configured, in a plan view, by a plurality of near-circular parts CP overlapped with each other. The outlet  20  capable of building up such foam object FB with intended shape may have a plurality of near-circular, widely-opened parts  24  respectively narrowed from the plurality of near-circular parts CP, and a linear narrowly-opened part  22  that mutually connects the widely-opened parts  24 . In this case, as with the foam dispenser attachment  12  of the fifth embodiment, the extension part  70  may be provided inside the widely-opened part  24 . With such design, the pointed part that typically represents eyes, nose or the like may be formed in the foam object FB having various characters&#39; shapes, within a single or a plurality of near-circular parts CP. In this case, a plurality of extension parts  70  may be provided to the head part  30 , and the extension parts  70  may be arranged respectively inside the plurality of widely-opened parts  24 . 
     Sixth Embodiment 
       FIG. 27A  and  FIG. 27B  are schematic bottom views of a foam dispenser attachment  13  of a sixth embodiment. The foam dispenser attachment  13  of the sixth embodiment is different from the foam dispenser attachment  12  of the fifth embodiment, in that the outlet  20  is composed of a plurality of discretely arranged openings. It is also different in that the extension part  70  is provided in a region between the plurality of openings and having no opening formed therein. 
     The dispensing direction DD of the foam B dispensed through the outlets  20  points frontwards of this sheet of  FIG. 27A . The foam B dispensed through the outlets  20  configure the near-circular parts CP in the foam object FB. The distance between the plurality of outlets  20  is preset to a predetermined value, and the plurality of near-circular parts CP are mutually crowded on the dispensing target plane TP (see  FIG. 21 ) to build up a single lump of foam object FB. 
     Meanwhile, the foam dispenser attachment  13  of this embodiment is same as the foam dispenser attachment  12  of the fifth embodiment in that at least the front end part  74  of the extension part  70  is provided within the area where the foam object FB with intended shape will be built up. The foam dispenser attachment  13  of this embodiment is also same as the foam dispenser attachment  12  of the fifth embodiment, in that the extension part  70  has the front end part  74 , and a rod-like stem part  76  made narrower than the front end part  74 . 
     The stem part  76  of the extension part  70  is preferably formed so as to suspend downward from the bottom face  31  of the foam dispenser attachment  13 . More preferably, the stem part  76  of the extension part  70  is provided at the middle point relative to the plurality of outlets  20 . 
     According to the foam dispenser attachment  13  of the sixth embodiment, by using the extension part  70  as a spacer so as to be brought into contact with the dispensing target plane TP, the outlet  20  and the dispensing target plane TP are kept at the predetermined distance SP (see  FIG. 21 ), and thereby the foam object FB may be built up with higher reproducibility. When the foams B dispensed through the plurality of outlets  20  to configure the near-circular parts CP are crowded to build the foam object FB, the front end part  74  provided at the middle point of these plurality of outlets  20  contact the foams B. This prevents shortage of the foam B at the middle point. More specifically, while the foam B may be dispensed abundantly right under the plurality of outlets  20 , whereas the foam B would sometimes be insufficient at the middle point between the outlets  20 . In contrast, when the foams B that swell after dispensed come into contact with the extension part  70 , the foams B will be gathered to the middle point to be flattened as a whole, as the extension part  70  is lifted up. That is, the phrase stating that “the extension part  70  is used as a shaping member” includes, not only the case where the pointed part P is created in the foam object FB, but also the case where the foam B is flattened so as to give the intended shape of the foam object FB. 
     Seventh Embodiment 
       FIG. 28  is an explanatory drawing illustrating a structure of a foam dispensing container  110  according to a seventh embodiment of this invention. The foam dispensing container  110  of the seventh embodiment is different from the second embodiment in that it has the extension part  70 , leaving the other aspects in common. 
     In the foam dispensing container  110  of this embodiment, the foam dispenser attachment  10  is disposed inside the enclosure  99 , leaving the outlet  20  exposed from the enclosure  99 . The foam dispenser attachment  10  is provided to the head part  30  that protrudes from the enclosure  99  nearly in the horizontal direction. 
     The foam dispenser attachment  14  of this embodiment has a pair of extension parts  70  opposed while placing the outlet  20  in between, like the foam dispenser attachment  10  of the third embodiment. The front end parts  74  of the extension parts  70  are positioned below the outlets  20  beyond the front end position thereof, with respect to the dispensing direction DD. 
     The sensing part  96  has a touch sensor that detects touching on the extension parts  70  or pressing of the extension parts  70 . When the user makes his or her palm contact to the front end parts  74  of the extension parts  70 , or pushes the front end parts  74  of the extension parts  70  upward by his or her palm with a predetermined force, the sensing part  96  as the touch sensor detects the load of contact or pressurizing, and sends a detection signal to the control unit  95 . With such design, the foam B will be dispensed through the outlet  20  when the dispensing target plane TP (palm) comes into contact with the front end parts  74  of the extension parts  70 . The distance SP (see  FIG. 21 ) between the outlet  20  and the dispensing target plane TP will thus be kept constant, and the reproducibility of the built-up foam object FB will be improved. 
     Style of sensing with the sensing part  96  is not limited to as described above, allowing various modifications. For example, for the foam dispensing container  110  used in bright places, the sensing part  96  may detect that the circumstance of the outlet  20  turned dark. In this case, an illuminance sensor is used as the sensing part  96 . It is recommendable to provide the extension part  70  that surrounds the circumference of the outlet  20  in a go-around manner, like the foam dispenser attachment  10  of the fourth embodiment illustrated in  FIG. 24 , to the head part  30 . When the sensing part  96  detects that the user brings his or her palm (dispensing target plane TP) into close contact with the bottom end of the extension part  70  to lower the illuminance inside the extension part  70  down to a predetermined threshold level or below, the control unit  95  activates the pump mechanism  92  and makes it dispense a predetermined amount of foamy liquid agent L through the outlet  20 . 
     The embodiments of this invention have been described above referring to the attached drawings, merely as examples of this invention. Various configurations other than those described above may be adoptable. 
     For example, although the embodiments have exemplified that a lump of foam object FB is built by dispensing, this invention is not limited thereto. When the foam object FB having a plurality of lump portions is built up by dispensing, it is recommendable to configure the outlet with a plurality of partial outlets corresponded to the individual lump portions. 
     The structures of the nozzle assembly  50  illustrated in  FIG. 4  and the foam dispensing container  110  illustrated in  FIG. 15  are merely those for exemplary purposes, allowing employment of other various configurations for the mechanism of delivering the liquid agent L having been reserved in the container body  40  to the foam dispenser attachment  10 . 
     The embodiments above have exemplified that the liquid agent L reserved in the liquid form in the container body  40  was introduced into the foam dispenser attachment  10  after transformed into foam. More specifically, the air-liquid contact portion  51  was disposed inside the nozzle assembly  50  in the first embodiment (see  FIG. 6 ), and the air-liquid contact portion  94   b  was disposed in the middle of the tube path  94   a  in the second embodiment (see  FIG. 15 ). Alternatively, the air-liquid contact portion may be provided inside the foam dispenser attachment  10 . In other words, the liquid agent L in the liquid form may be introduced from the container body  40  to the foam dispenser attachment  10 , transformed into foam within the foam dispenser attachment  10 , and then dispensed through the outlet  20 . For example, the air-liquid contact portion such as mesh may be provided to the outlet  20 . 
     A valve may be provided in the vicinity of the outlet  20 . The valve may be an on-off valve which is pushed open by the foam B passing through the outlet  20  and is closed upon termination of dispensing of the foam B, which is exemplified by a self-closing valve described in Patent Literature 5 described above. The outlet  20  may preferably be provided inside the dispensing guide  26 , or outside the dispensing guide  26  and neighboring thereto so as to cover the outlet  20 . Provision of the valve will prevent the liquid agent L that remains within the head part  30  from drying up, and will effectively prevent the outlet  20  from being clogged. 
     Although the third to sixth embodiments have exemplified the case where the extension part  70  was integrally provided with the foam dispenser attachments  10  to  14  having the outlet  20 , this invention is not limited thereto. The foam dispenser attachments  10  to  14  may be configured with a plurality of members, and one member having the outlet  20  and the other member having the extension part  70  may be separately fixed to the head part  30  (pump head part  32 ). 
     The fifth and sixth embodiments have exemplified the case where one pillar-like extension part  70  was formed on the foam dispenser attachment  10  so as to protrude in parallel to the dispensing direction DD, or, downward (see  FIGS. 25A to 25C  and  FIGS. 26A to 26B ). Alternatively, a plurality of extension parts  70  may be provided to the foam dispenser attachment  10 , or the extension part  70  that diagonally lies in the direction crossing the dispensing direction DD may be provided. Provision of the plurality of extension parts  70  will stabilize the direction of the dispensing target plane TP faced to the outlet  20 , when the front end parts  74  of the individual extension parts  70  are brought into contact with the dispensing target plane TP. 
     In conjunction with the embodiments described above, this invention herein will disclose a foam dispensing container and a foam dispenser attachment below. 
     &lt;1&gt; A foam dispensing container that includes a container body that reserves a liquid agent; a head part that has an outlet, and dispenses the liquid agent delivered from the container body through the outlet into foam; and a dispensing operation part that allows dispensing of a predetermined amount of the foamy liquid agent through the outlet each time it accepts a user&#39;s operation, 
     the outlet being an opening with a contiguous geometry narrowed from an intended shape, and being designed to build up the foamy liquid agent, dispensed through the outlet as a result of a single or multiple operations made on the dispensing operation part, into the intended shape in a plan view seen in the dispensing direction. 
     &lt;2&gt; The foam dispensing container according to &lt;1&gt;, wherein the outlet has a linear narrowly-opened part; and a widely-opened part that communicates with the narrowly-opened part and is made wider than the narrowly-opened part. 
     &lt;3&gt; The foam dispensing container according to &lt;2&gt;, wherein the widely-opened part is near circular with a diameter larger than a width of the narrowly-opened part. 
     &lt;4&gt; The foam dispensing container according to any one of &lt;1&gt; to &lt;3&gt;, wherein the head part has a reservoir that reserves the foamy liquid agent delivered from the container body, and the reservoir has a ceiling that inclines towards the front end side of the feeding direction of the liquid agent, and downward towards the outlet.
 
&lt;5&gt; The foam dispensing container according to &lt;4&gt;, wherein the head part has a nozzle part that dispenses the foamy liquid agent delivered from the container body in an obliquely downward direction into the reservoir; and an inclined face that is provided in the reservoir so as to nearly confront the obliquely downward direction, and
