FR 3022125 A1 20151218 FR 1555335 A 20150611 SPECIFICATION TITLE OF THE INVENTION APPLICATOR 10 BACKGROUND OF THE INVENTION (1) Field of the Invention [0001] The present invention relates to applicators for applying application liquids such as liquid rouge, liquid foundation, 15 creamy makeup and the like. (2) Description of the Prior Art [0002] In general, the applicators for applying application liquids such as liquid cosmetics and the like are constructed 20 such that the application liquid is pushed out from a reservoir disposed in the barrel to the delivery port of the application body arranged at a barrel front and can be applied to an object such as the skin and the like. [0003] 25 Since the application body, especially when used for cosmetics, isdemanded to present a suitable contact feeling to be applied to the skin, the application body is generally formed of resin. [0004] In the applicator of this kind, when the application body is formed as a thick-walled molding, there may occur the problem of sink marks appearing in the application body due to shrinkage after molding. Sink marks appear as unwanted thin-walledareasandvoids, causing production defects , hence are wanted to be prevented. [0005] Also, in order to stabilize forming of the application body, provision of reduced thickness parts can be considered. [0006] When a hollow application body is used, use of a container including a pressurizing and extruding mechanism using a piston or the like can be considered. The present applicator has proposed a Patent Document 1 as a liquid applicator of this type. [0007] However, in the liquid applicator with a hollow application body of this kind, there occur cases where the liquid is left over inside the application body without being able to squeeze out the last drops of liquid. [0008] As a measure to prevent the liquid from being left over, there has been a known configuration (see Patent Document 2) in which a communication passage for leading the application liquid into the application body is made thin. However, in this case, the communication passage becomes long and narrow, there is a risk of the liquid clogging in the communication passage if the application liquid dries up due to cases such that non-use period of the applicator becomes long. [0009] As anothermeasure for prevention against liquid residue, there has been proposals of providing a spacer inside the interior space of the application body (see Patent Documents 3 and 4). However, the conventional spacer configuration still entails the risk of the liquid being left over after the piston reaches the advance limit. [0010] Further, in the case where a spacer isused, there occurs the problem that the spacer becomes conspicuous, spoiling design performance of the applicator if the application body is formed of a transparent material. [0011] Moreover, because the liquid flows through the center of the spacer in the conventional configuration, the joint between the application body and the spacer is required to be hermetic, hence the configuration is likely to be complicated. [Prior Art Documents] [Patent Documents] [0012] Patent Document 1: Japanese Patent Application Laid-open 2012-135465 Patent Document 2: Japanese Patent Application Laid-open 2014-4084 Patent Document 3: Japanese Patent Application Laid-open H06-22816 Patent Document 4: Japanese Patent Application Laid-open 2005-87562 SUMMARY OF THE INVENTION [0013] Under the above circumstance, the present invention is to provide an applicator that can cut down the volume of the space inside the application body and suppress the residual liquid by providing a spacer inside the application body and that is not required to be hermetic at the joint between the application body and the spacer. [0014] The first aspect of the present invention resides in an applicator for delivering an application liquid from a delivery port to an outside by way of an interior space of an application body, comprising: an application body; and, a spacer inserted in an interior space of the application body, wherein a clearance between an exterior face of the spacer and an interior face of the application body forms a communication passage for flowing an application liquid, and the application liquid is delivered from a delivery port of the application body by way of the communication passage. [0015] The second aspect of the present invention is characterized in that a projected area is formed in a vicinity of the delivery port on one of the exterior face of the spacer and the interior face of the application body, facing the clearance, and the clearance in the vicinity of the delivery port is made narrower than the clearance in the other area than the vicinity of the delivery port. [0016] The third aspect of the present invention is characterized in that the application body is formed to be transparent or translucent so as to make the application liquid in the interior space visible. [0017] The fourth aspect of the present invention is characterized in that the spacer is formed with a communication hale for connecting the clearance with an application liquid supply side. [0018] The fifth aspect of the present invention is characterized in that an indentation is formed in one of a rear end of the spacer and a rear end of the application body while a projection is formed in the other thereof so that the projection and the indentation are engaged to assure anti-rotation. [Advantages of the Invention] [0019] According to the applicators of the present invention, the volume of the interior space of the application body can be cut down by providing the spacer inside the application body. Since the application liquid is flowed through the clearance between the application body and the spacer, it is possible to suppress the residual liquid on the spacer. Further, since the application liquid is flowed inside the application body, hermeticity is not demanded for the joint between the application body and the spacer. [0020] Herein, depending on the position of the delivery port in the application body there is a risk that liquid unfilled part is formed in the clearance between the application body and the spacer, spoiling the external appearance due to generation of air bubbles. To deal with this, for the clearance in the vicinity of the delivery port, the projected area is formed on one of the spacer's exterior face and the application body's interior face, which are facing the clearance, so as to make the clearance in the vicinity of the delivery port narrower than the clearance in the other area than the vicinity of the delivery port. By this arrangement, it is possible to delay ejection of the application liquid by the flow resistance of the application liquid arising from the narrowed clearance, whereby the application liquid can be fully or completely spread inside the application body, without generating air bubbles. Filling the interior of the application body with the application liquid makes it possible to achieve ejection of the application liquid without degrading the exterior appearance of the application body due to remaining air bubbles. [0021] In this case, forming the application body to be transparent or translucent to make the interior application liquidvisible, produces excellent advantage that the interior of the application body can be externally observed and fully confirmed.

Similarly, FIGS. lia ta 11h, FIGS. 12a ta 12h, FIGS. 13a ta 13h, FIGS. 14a ta 14h, FIGS. 15a ta 15h, FIGS. 16a ta 16h, FIGS. 17a ta 17h, FIGS. 18a ta 18h, FIGS. 19a ta 19h, FIGS. 20a ta 20h, and FIGS. 21a ta 21h may also be generally referred ta as FIG. 11, FIG. 12, FIG. 13, FIG. 14, FIG. 15, FIG. 16, FIG. 17, FIG. 18, FIG. 19, FIG. 20 and FIG. 21, respectively. [0025] As shown in FIGS . 1 ta 10, any of the applicators according ta embodiments 1 ta 10 is configured sa that the application liquid stored in a reservoir space 20 in a barrel main body 10 is supplied ta an application body 14 formed of an elastic material at the front end of the main body 10 by a liquid pressurizingmechanism 12 attached ta the main body 10 while the application body 14 isabutted against an abject ta apply the application liquid ta the abject. [0026] Detailedly, the applicator includes the main body 10, the application body 14, the spacer 16, the application liquid reservoir space 20 for storing the application liquid and the liquid pressurizing mechanism 12 . Though the applicators of FIGS. 1 to 10 can be attached with a removable cap (not shown), the state with the cap removed is shown. [0027] The main body 10 has an approximately cylindrical shape narrowed in the front end where a main body small-diametric part 10a is formed. An unillustrated cap can be removably fitted to the main body small-diametric part 10a. The space enclosed by the spacer 16 and a piston body 22 inside the main body 10 forms the application liquid reservoir space 20. As the piston body 22 is advanced in the main body 10 by the liquid pressurizing mechanism 12, the volume of this application liquid reservoir space 20 is decreased so as to pressurize the application liquid and send out the application liquid toward the application body 14. [0028] The liquidpressurizingmechanism 12 includes the piston body 22 and a drive mechanism ( formed of a rotational actuator 30, an axis-like member 24, a threaded part 26, an advancing element 28 and the like). The piston body 22 is configured to move forward and backward relative to the application liquid reservoir space 20 inside the main body 10 to decrease and increase the volume of the reservoir space. The drive mechanism (formed of the rotational actuator 30, the axis-likemember 24, the threadedpart 26, the advancing element 28 and the like) has the front part of the axis-like member (also referred to as threaded rod) 24 engaged with the rear part of the piston body 22 and moves this axis-like member 24 forward and backward to advance and retract the piston body 22 as the user applies operational force. [0029] The rotational actuator 30 is a cylindrical handle that is fitted in an unrotatable manner on the rear end part of the advancing element 28. The front end of the advancing element 28 is fitted into the rear end of the main body 10. The center in the front end of the advancing element 28 is formed with a variant-shaped hole (the aftermentioned cam shape), into which the axis-like member 24 (having a contour of the variant-shaped cam shape) is inserted. The axis-like member 24 is fittedso as to be movable in the axial direction and unrotatable relative to advancing element 28. [0030] The annular threaded part 26 having two cup-like forms on front and rear ends is arranged in an unrotatable manner in main body 10. The front part of the advancing element 28 is inserted into the cut-like space formed on the rear side in the threaded part 26. Ameshing portion between the inner periphery of the threaded part 26 in the front part and the outer periphery of the advancing element 28 is formed with a toothedratchet 28a, which limits rotation of the advancing element 28 (rotational actuator 30) or permits the advancing element to turn in one direction only relative to the threaded part 26. When the applicator is provided with a pressurizing and depressurizing mechanism, the advancing element is not restricted on rotation but is adapted to be rotatable in both directions with a clicking sensation. [0031] The male thread on the outer periphery of the axis-like member 24 are screw fitted with the female thread formed in the center bore of the threaded part 26. [0032] The cross section of the axis-like member 24 has a variant cam shape while the center bore of the engaging portion of the advancing element 28 as a part of the rotational actuator is formed with the variant cam shape corresponding to the outer periphery of the axis-like member 24. The axis-like member 24 is inserted into the center bore of the engaging portion and engaged with the advancing element 28 so as to be slidable in the axial direction and unrotatable relative to the advancing element 28. [0033] The front end part of the axis-like member 24 is coupled to the piston body 22. As the rotational actuator 30 is turned in the predetermined direction, the axis-like member 24 advances the piston body 22 toward the front end of the main body 10 via the threaded part 26 to pressurize the application liquid in the application liquid reservoir space 20 of the main body 10 and send the liquid to the application body 14. [0034] Here in the applicators of the embodiments 1 to 10, the application body 14 has the spacer 16 inserted in the interior space thereof. The spacer 16 is attached forming a clearance 32 between the interior face 14a of the application body 14 and the exterior face 16a of the spacer 16. Formed at the front end part of the application body 14 is a delivery port 14b that penetrates from the inside to the outside to deliver the application liquid out from within. [0035] The front part of the external face of the application body 14 is formed with a sloping exterior surface, inclined about 20° to 45° relative to the axis. This sloping surface mainly forms an applying face 14c. The rear cylindrical portion of the application body 14 is fitted into the main body small-diametric portion 10a in the front end of the main body 10. The application body 14 and the main body are joined so as not to slip off from each other with fitting and engagement between indentations and projections formed on the outer periphery of the cylindrical portion of the application body 14 and the inner periphery of the main body small diametric portion 10a. [0036] An 0-ring 18 as a sealing member is interposed between the outer periphery of the application body 14 and the inner periphery of the main body small diametric portion 10a, so that the application liquid pressed and sent out by the liquid pressurizing mechanism 12 will not leak. [0037] The clearance 32 between the exterior face 16a of the spacer 16 and the interior face 14a of the application body 14 serves as a communication channel, through which the application liquid is ejected from the delivery port 14b. [0038] Provision of the spacer 16 inside the application body 14 can cut down the volume of the interior space of the application body 14. Accordingly, it is possible to suppress the residual liquid in the application body 14. [0039] Passage of the application liquid through the clearance 32 between the application body 14 and the spacer 16 assures design performance before use by virtue of the flow-out of the application liquid such as ink or the like and can suppress liquid residue in the application body 14 after use. [0040] In the application bodies 14 according to the embodiments 1 to 4 and 8 to 10, an application body-side projected area 34 or a spacer-side projected area 36, which is projected one step higher from the interior face (inner wall) of the application body 14 or the exterior face (outer surface) of the spacer 16, is formed in the vicinity of the deliver port 14b (delivery port 14b and therearound). As a result, the clearance (second clearance) between the interior face (inner wall) of the application body 14 and the opposite spacer-side projected area 36 is formed smaller than the clearance 32 (first clearance) between the interior face (inner wall) of the application body 14 and the opposite exterior face of the spacer 16 (other than the spacer-side projected area 36). Similarly, the clearance 32b (second clearance) between the application body-side projected area 34 and the opposite exterior face of spacer 16 is formedsmaller than the clearance 32 (first clearance) between the interior face (other than the application body-side projected area 34) of the application body 14 and the opposite exterior face of the spacer 16. In the above case, the spacer-side projected area 36 is formed in the area opposite to the delivery port 14b and its surrounding, for easy forming. However, this may formed in the area opposite to only the surrounding area of the delivery port 14b only. Further, in the application bodies 14 according to the embodiments 1 ta 4 and 8 ta 10, formation of either the application body-side projected area 34 or the spacer-side projected area 36 alone is exemplified. However, bath the application body-side projected area 34 and the spacer-side projected area 36 may be formed. [0041] The application body 14 is formed of transparent or translucent resin that makes the interior application liquid visible. [0042] Specifically, the application body 14 may be formed of a resin material capable of achieving the necessary performance for application, in particular, highly transparent, silicone resin, acrylic resin, polyester resin or the like, formedbyLIMmolding, injectionmoldingorothers. [0043] Preferable examples of the application liquid include various cosmetics. Also, preferable examples of the application liquid include liquid chemicals. Some of them may contain silicone oil. [0044] The material of the application body 14 is usually selected taking into account the compatibility with the application liquid. Other than this, diverse evaluation items such as hardness, surface conditions, transparency and the like are considered for selection. [0045] Accordingly, the application liquid in the embodiments employs liquid containing silicone oil on the assumption that a typical highly transparent resin such as acrylic resin or the like is used for the application body 14. [0046] Depending on the position of the delivery port 14b in the application body 14, there is a risk that unfilled part with the application liquid is formed in the clearance 32 between the application body 14 and the spacer 16, hence spoiling the external appearance due to generation of air bubbles. In order to prevent such generation of air bubbles, the distance between the inner wall around the delivery port 14b and the outer surface of the spacer 16 is made closer than the distance between the inner wall other than the vicinity (the surrounding area) of the delivery port 14b and the outer surface of the spacer 16, by forming a step such as a swelled portion or other projection (the step formed by application body-side projected area 34 or spacer-side projected area 36). That is, the clearance 32b (second clearance) in the vicinity (surrounding portion) of delivery port 14b is made narrower compared to the clearance 32 (first clearance) in the area other than the vicinity (surrounding portion) of the delivery port 14b. [0047] Narrowing the clearance 32 in the vicinity (surrounding portion) of the delivery port 14b causes delay of ejection due to flow resistance of the liquid, thus making it possible to fill the whole clearance 32 with between the spacer 16 (exterior face 16a) inside the application body 14, with the application liquid. The application liquid can be made to uniformly fill the interior of the application body 14 so that it is possible to achieve ejection of the liquid with improved appearances, without degrading the exterior appearance of the application body 14 due to remaining air bubbles. [0048] In particular, when the application body 14 is transparent or translucent, the flow condition of the application liquid inside the application body 14 can be well observed through the application body 14, and when the application liquid is a fluid cosmetic for makeup, the user will look at the application body when the user puts the applicator on the skin. If the user is able to confirmuniform filling of the interior of the application body 14 with the application liquid, the user can expect continuous delivery of the cosmetic without any breaks, hence apply make-up comfortably and feel at easy from the comfort. [0049] In order to establish connection between the clearance 32 and the application liquid reservoir space 20 side, the spacer 16 is formed with a communication hale 16b (communication hale 16b1 on the front side, communication hale 16b2 on the rear side, wall-shaped step 16c) and/or a communication groove 40(see FIG. 19). [0050] A projection 42 (FIGS. 20a to 20d and 20h) is formed at the rear end of the spacer 16 while an indentation is formed at the rear end of the application body 14 so as to achieve anti-rotation by means of engagement between the projection 42 and the indentation. As another configuration, the indentation may be formed in the spacer while the projection may be formed in the application body. The projection and indentation may be modified with appropriate shape of indentations and projections. [0051] Examples of the application body 14 include application bodies 14A to 14D shown in FIGS. 11 to 14. Examples of the spacer 16 include spacers 16A to 16G shown in FIGS. 15 to 21. Embodiments 1 to 10 shown in FIGS. 1 to 10 each use a combination of application body 14 and spacer 16 shown in Table 1 below. [0052] [Table 1] Combination Application Application Application Application Body 14D Body 14A Body 14B Body 14C Spacer 16A Embodiment 1 Spacer 16B Embodiment 2 Spacer 16C Embodiment 5 Embodiment 3 Spacer 16D Embodiment 6 Embodiment 4 Spacer 16E Embodiment 7 Embodiment 8 Spacer 16F Embodiment 9 Spacer 16G Embodiment 10 [0053] Next, examples of the application body 14, application bodies 14A to 14D will be described. Application bodies 14Ato 14D each have a configuration as in Table 2 below. [0054] [Table 2] Application Body Configuration Step Anti-rotation Application Body 14A None None Application Body 14B Formed None Application Body 14C None 1 place Application Body 14D None 2 places [0055] Ail the application bodies 14A to 14D each have an approximately bag-like configuration in which the front end other than the delivery port 14b is closed while the rear end is cylindrically opened. [0056] In the application body 14A, as shown in FIG. 11, an applying face 14c is roughly a slope inclined to the axis and formed to have a slightly arced swelling surface with a delivery port 14b perforated at the front endof the applying face 14c. Of the inner surface of application body 14A or the applicationbody interior face 14a (FIG. 11e), the interior side of the applying face 14c is formed flat. On the otherhand, of the application body interior face 14a, the interior front end face, designated at 14a1 (FIGS. lle and 11g) under the delivery port 14b (located on the front side of the delivery port 14b in the application body 14A), is formed with a predetermined curvature forming an arc. [0057] As shown in FIG. 12, the application body 14B has an applying face 14c of a swelling slope similar to that of the application body 14A with a delivery port 14b perforated at the front end of the applying face 14c. [0058] Of the inner surface of application body 14B or the application body interior face 14a (FIG. 12e), the interior side of the applying face 14c (FIG. 12e) is formed so that the peripheral area of the delivery port 14b is stepped and made thicker, forming an application body-side proj ected area 34 (FIG. 12e). Further, in the interior side of the applying face 14c (FIG. 12e), the interior front end face, designated at 14a1 (FIGS. 12e and 12g) under the delivery port 14b (located on the front side of the delivery port 14b in the application body 14B), is formed with a corner of an angle. The other configurations are the same as those of the application body 14A, so the same components are allottedwith the same reference numerals. [0059] In the application body 14C, as shown in FIG. 13, an applying face 14c is roughly a slope inclined to the axis and formed to have a slightly arced swelling surface. A delivery port 14b isperforated at the front endof the applying face 14c. Of the inner surface of the application body 14C or the application body interior face 14a (FIG. 13e), the interior side of the applying face 14c is formed flat. The interior face 14a has an inner front end face 14a1 (FIG. 13e) formed around the delivery port 14b in an acute angle in the vertical section, and part of the inner face of the delivery port 14b is linearly extended rearward contiguously to the interior face 14a. Further, an indentation 38 for preventing rotation when the spacer 16 (spacer 16F in FIGS. 20a to 20h) is attached (and engaged with projection 42) is formed at a place on the slope side at the rear end of the rear cylindrical part of the application body 14C. The other configurations are the same as those of the application body 14B, so the same components are allotted with the same reference numerals. [0060] In the application body 14D, as shown in FIG. 14, an interior face 14a, applying face 14c, delivery port 14b and others are formed in the same manner as in the application body 14C. The rear end of the rear cylindrical part of the application body 14D is formed on both sides thereof with two indentations 38 for preventing rotation when the spacer 16 (projections 42 of the spacer 16G in FIG. 21) is attached (and engaged with projections 42). The other configurations are the same as those of the application body 14C, so the same components are allotted with the same reference numerals. [0061] Next, examples of spacer 16, spacers 16A to 16G will be described. Spacers 16A to 16G each have a configuration as in Table 3 below. [0062] [Table 3] Spacer Configuration Step Communication Ho le Anti-rotation Spacer 16A Formed 1 round hole None Spacer 16B Formed 2 round holes None Spacer 16C None 1 round hole None Spacer 16D None 2 round holes None Spacer 16E None None None Spacer 16F Formed 2 rect. holes 1 place Spacer 16G Formed 2 rect. holes 2 places [0063] As shown in FIG. 15, the spacer 16A has a slope on the front end side of the exterior face 16a, part of the slope being projected one step higher forming the spacer-side projected area 36. A communication hole 16b1 is formed from the rear part of the slope (on the side of the slope opposite from the spacer-side projected area 36) to form an opening. The spacer 16A has the communication hole 16b1 and a communication hole 16b2. The communication hale 1 6b1 has a U-shaped cross-section, and is linearly extended in the axial direction from the slope of exterior face 16a of the spacer 16A along the external surface of the spacer 16A. The front end of the communication hole 16b1 is open obliquely along the slope. The communication hole 16b2 is arranged in the rear cylindrical part of the spacer 16A (on the application liquid reservoir space 20 side), being formed in the axial center of the spacer 1 6Awith a greater diameter than the communication hale 16b1 (see FIG. 15e) . That is, the communication hale 16b2 is formed wider than the communication hale 16b1. The communication hale 16b2 is connected via a stepped wall 16c at its front end with the communication hale 16b1 while the rear end is connected ta the application liquid reservoir space 20. At the stepped wall 16c, part of the opening of the communication hale 16b1 communicates with part of the opening of the communication hale 16b2 (see FIG. 15e) . An annular flange is formed at the rear end of spacer 16A. [0064] Similarly to the spacer 16A, as shown in FIG. 16, a spacer 16B has a slope on the front end side of an exterior face 16a, part of the slope being projected one step higher forming the spacer-side projected area 36. [0065] Differing from the spacer 16A, openings of communication hales 16b1 are formed on bath sides in the middle part of the spacer, instead of the slope. In the spacer 16B, a thick communication hale 16b2 is formed in the axial center on the rear side while the small-diametric communication hales 16b1 are formed radially outward along the stepped wall 16c and opened on the outer peripheral of the spacer 16B. The other configurations are the same as those of the spacer 16A. [0066] As shown in FIG. 17A, a spacer 16C has a slope on the front end side of an exterior face 16a, the slope being formed to be flat without any step. Acommunication hale 16blhaving anopeningisformedfrom the rear part of the slope. Similarly to the spacer 16A, a thick communication hole 16b2 is formed in the axial center on the rear side, extended forward and connected to the thin communication hole 16b1 at a stepped wall 16c, the communication hole 16b1 being opened on the slope. The other configurations are the same as those in the spacer 16A. [0067] Similarlyto the spacer 16B, as shown in FIG. 18, a spacer 16D has a slope on the front end side of an exterior face 16a but formed to be flat without any step. Further, similarly to the spacer 16B, openings of communication holes 16b1 are formed on both sides in the middle part of the spacer, instead of the slope, and connected to a communication hole 16b2 in the rear of the spacer via a stepped wall 16c. The other configurations are the same as those in the spacer 16B. [0068] Similarly to the spacer 16D, as shown in FIG. 19, a spacer 16E has a slope on the front end side of an exterior face 16a formed ta be flat without any step. However, differing from the spacer 1 6D and others , no communication hale is formed while communication grooves 40 for flowing the application liquid are formed on bath sides. Each communication groove 40 extends from the cutout in the flange on the rear side ta the front side sa as ta be able ta lead the application liquid ta the flat exterior face 16a. The other configurations are the same as those in the spacer 16D. [0069] Similarly ta the spacer 16B, a spacer 16F has a slope on the front end side of an exterior face 16a, part of the slope being projected one step higher forming a spacer-side proj ected area 3 6, as shown in FIG . 20. Similarly to the spacer 16B, the spacer 16F has communication hales 16b1 each having an opening formed on bath sides in the middle part thereof, instead of the slope. However, differing fromthe spacer 16B, the shape of the opening of the communication hale is rectangular. [0070] Further, a projection 42 for anti-rotation is formed in the flange at the rear end on the slope side. The other components are the same as those in the spacer 16B, sa the same reference numerals are allotted. [0071] Similarly to the spacer 16F, as shown in FIG. 21, a spacer 16G has a slope on the front end side of an exterior face 16a, part of the slope being projected one step higher forming a spacer-side projected area 36. The spacer 16G has communication holes 16b1 of rectangular shape openings formed on both sides. [0072] Further, two projections 42 for anti-rotation are formed in the flange at the rear end, at positions corresponding to the positions of the openings of the communication holes 16b1. The other components are the same as those in the spacer 16F, so the same reference numerals are allotted. [0073] The applicator of the embodiment 1 is configured as shown in FIG. 1 by attaching the spacer 16A (see FIG. 15) as the spacer 16 to the application body 14A (see FIG. 11) as the application body 14. In this applicator, as the application liquid is sent out by means of the liquid pressurizing mechanism 12, the application liquid passes through the communication hole 16b1 on the slope side of the exterior face 16a and reaches the clearance 32. Since the application liquid enters the clearance 32 from the upper side of the delivery port 14b (the far side from the delivery port 14b) , the liquid is sent from the upper side to the steps forming the spacer-side projected area 36 as shown by the broken line in FIG. le. The spacer 16 and the application body 14 become closer to each other in the spacer-side projected area 36 surrounding the delivery port 14b, hence the clearance 32 is narrowed. Accordingly, the application liquid isdelayed to be ejected from delivery port 14b due to flow resistance, so that the application liquid can fill the whole clearance 32 between the spacer 16 and the interior of the application body 14. Thus, the application liquid can be made to uniformly fill the interior of the application body 14 so that it is possible to achieve ejection of the liquid with improved appearances, without degrading the exterior appearance of the application body 14 due to remaining air bubbles. [0074] The applicator of the embodiment 2 is configured as shown in FIG. 2 by attaching the spacer 16B (see FIG. 16) as the spacer 16 to the application body 14A (see FIG. 11) as the application body 14. In this applicator, as the application liquid is sent out by means of the liquid pressurizing mechanism 12, the application liquid passes through the communication holes 16b1 on both sides of the exterior face 16a of the spacer 16B and reaches both sides of the clearance 32. Since the application liquid enters the clearance 32 from thebothsides, the liquid is easily branched into the upper and lower sides and sent to the clearance 32 as shown by the broken lines in FIG. 2e. [0075] The spacer 16 and the application body 14 become closer in the area surrounding the delivery port 14b to each other in the spacer-side projected area 36 of the spacer 16B, hence the clearance 32 is narrowed to be a clearance 32b. Accordingly, the application liquid is delayed to be ejected from delivery port 14b due to flow resistance, so that the application liquid can fill the whole clearance 32 between the spacer 16 and the interior of the application body 14. The other operation and effect are the same as in the applicator of the embodiment 1. [0076] The applicator of the embodiment 3 is configured as shown in FIG. 3 by attaching the spacer 16C (see FIG. 17) as the spacer 16 to the application body 14B (see FIG. 12) as the application body 14. In this applicator, as the application liquid is sent out by means of the liquid pressurizing mechanism 12, the application liquid passes through the communication hale 16b1 on the slope side of the exterior face 16a and reaches the clearance 32. Since the application liquid enters the clearance 32 from the upper side of the delivery port 14b (the far side from the delivery port 14b), the liquid is sent toward the step of the application body-side projected area 34, as shown by the broken line in FIG. 3e. [0077] The spacer 16 and the application body 14 become closer to each other in the application body-side projected area 34 of the interior face 14a of the application body 14, hence the clearance 32 is narrowed in the surrounding area of the delivery port 14b. Accordingly, the application liquid is delayed to be ejected from delivery port 14b due to flow resistance, so that the application liquid can fill the whole clearance 32 between the spacer 16 and the interior of the application body 14. The other operation and effect are the same as in the applicator of the embodiment 1. [0078] The applicator of the embodiment 4 is configured as shown in FIG. 4 by attaching the spacer 16D (see FIG. 18) as the spacer 16 to the application body 14B (see FIG. 12) as the application body 14. In this applicator, as the application liquid is sent out by means of the liquid pressurizing mechanism 12, the application liquid passes through the communication holes 16b1 on the sides of the exterior face 16a and reaches the clearance 32. Since the application liquid enters the clearance 32 from the both sides of the spacer 16, the liquid is easily branched into the upper and lower sides and sent to the clearance 32 as shown by the broken lines in FIG. 4e. [0079] The spacer 16 and the application body 14 become closer to each other in the application body-side projected area 34 of the interior face 14a of the application body 14, hence the clearance 32 is narrowed in the surrounding area of the delivery port 14b. Accordingly, the application liquid is delayed to be ejected from delivery port 14b due to flow resistance, so that the application liquid can fill the whole clearance 32 between the spacer 16 and the interior of the application body 14. The other operation and effect are the same as in the applicator of the embodiment 3. [0080] The applicator of the embodiment 5 is configured as shown in FIG. 5 by attaching the spacer 16C (see FIG. 17) as the spacer 16 to the application body 14A (see FIG. 11) as the application body 14. In this applicator, as the application liquid is sent out by means of the liquid pressurizing mechanism 12, the application liquid passes through the communication hole 16b1 on the slope side of the exterior face 16a and reaches the clearance 32. Since the application liquid enters the clearance 32 from the upper side of the delivery port 14b (the far side from the delivery port 14b) , the liquid flows as shown by the broken line in FIG. 5e and can fill the clearance 32 between the spacer 16 and the interior of the application body 14. [0081] The applicator of the embodiment 6 is configured as shown in FIG. 6 by attaching the spacer 16D (see FIG. 18) as the spacer 16 ta the application body 14A (see FIG. 11) as the application body 14. In this applicator, as the application liquid is sent out bymeans of the liquidpressurizingmechanism 12, the application liquid passes through the communication hales 16b1 on the sides of the exterior face 16a and reaches the clearance 32. Since the application liquid enters the clearance 32 from the bath sides, the liquid is branched into the upper and lower sides, entering the clearance 32 as shown by the broken lines in FIG. 6e. Thus, the application liquid can be made ta fill the whole the clearance 32 between the spacer 16 and the interior of the application body 14, keeping goodappearances. The other operation and effect are the same as in the applicator of the embodiment 5. [0082] The applicator of the embodiment 7 is configured as shown in FIG. 7 by attaching the spacer 16E (see FIG. 19) as the spacer 16 ta the application body 14A (see FIG. 11) as the application body 14. In this applicator, as the application liquid is sent out by means of the liquid pressurizing mechanism 12, the application liquid passes through the communication grooves 40 (FIGS. 19a ta 19d, 19g and 19h) defined between the sides of the spacer 16 and the interior face 14a of application body 14, entering the clearance 32 via the front, upper and lower sides, as shown by the broken lines in FIG. 7e. Thus, the application liquid can be made to fill the whole the clearance 32 between the spacer 16 and the interior of the application body 14 from the left and right sides of the spacer 16, keeping good appearances. [0083] The applicator of the embodiment 8 is configured as shown in FIG. 8 by attaching the spacer 16E (see FIG. 19) as the spacer 16 to the application body 14B (see FIG. 12) as the application body 14. In this applicator, as the application liquid is sent out by means of the liquid pressurizing mechanism 12, the application liquid passes through the communication grooves 40 defined between the sides of the spacer 16 and the interior face 14a of application body 14, entering the clearance 32. Thus, the application liquid passes through the clearance 32 as shown by the broken lines in FIG. 8e. [0084] The spacer 16 and the application body 14 become closer to each other in the application body-side projected area 34 of the interior face 14a of the application body 14, hence the clearance 32 is narrowed in the surrounding area of the delivery port 14b. Accordingly, the application liquid is delayed to be ejected from delivery port 14b due to flow resistance, so that the application liquid can fill the whole clearance 32 between the spacer 16 and the interior of the application body 14. The other operation and effect are the same as in the applicator of the embodiment 3. [0085] The applicator of the embodiment 9 is configured as shown in FIG. 9 by attaching the spacer 16F (see FIG. 20) as the spacer 16 to the application body 14C (see FIG. 13) as the application body 14. In this applicator, as the application liquid is sent out by means of the liquid pressurizing mechanism 12, the application liquid passes through the communication grooves 40 defined between the sides of the spacer 16 and the interior face 14a of application body 14, entering the clearance 32. Thus, the application liquid passes through the clearance 32 as shown by the broken lines in FIG. 9e. [0086] The spacer 16 and the application body 14 become closer to each other in the spacer-side projected area 36 of the spacer 16F, hence the clearance 32 is narrowed in the surrounding area of the delivery port 14b. Accordingly, the application liquid is delayed to be ejected from delivery port 14bdueto flow resistance, so that the application liquid can fill the whole clearance 32 between the spacer 16 and the interior of the application body 14. [0087] With the spacer 16F, the projection 42 (FIGS. 20a to 20d and 20h) fits to the anti-rotation indentation 38 (FIGS. 13b to 13c, 13e, 13g and 13h) of the application body 14C so as to stabilize the application body without causing any rotation during usage. [0088] The applicator of the embodiment 10 is configured as shown in FIG. 10 by attaching the spacer 16G (see FIG. 21) as the spacer 16 to the application body 14D (see FIG. 14) as the application body 14. The application liquid flows through the clearance 32 as shown by the broken lines in FIG. 10e. In this applicator, two projections 42 (FIGS. 21a to 21d, FIGS. 20f and 20h) fit intotwoanti-rotationindentations 38 (FIGS. 14b to 14d, 14e, 14g and 14h) of the application body C so as toprevent the application body 14d from a rotation and keep the application body 14D more stably during use than in embodiment 9. The other operation and effect are the same as in the embodiment 9. [0089] As has been described heretofore, according to the applicators of the embodiments 1 to 10, since spacer 16 is provided inside applicationbody 14, thisarrangementmarkedly contributes to reducing the volume of the space inside the application body 14 and suppressing liquid residue. [0090] Further, depending on the position of the delivery port 14b in the application body 14, there is a risk that liquid unfilled part is formed in the clearance 32 between the application body 14 and the spacer 16, spoiling appearances due ta generation of air bubbles . To deal with this , according ta the applicators of the embodiments 1 ta 4, 9 and 10, for the clearance 32 around the delivery port 14b, the application body-sideprojectedarea 34 or the spacer-sideprojectedarea 36 is formed in the vicinity of the deliver port 14b on the interior face of the application body 14 or the exterior of the spacer 16 each of which is facing the clearance 32, sa as ta farm a narrower clearance than the other part of the clearance 32. By this arrangement, it is possible ta delay ejection of liquid by the flow resistance of the application liquid arising from the narrowed clearance, whereby the application liquid can be fully or completely spread inside the application body, without generating air bubbles. [0091] Accordingly, filling the interior of the application body 14 with the application liquid makes it possible ta achieve ejection of the liquid without degrading the exterior appearance of the application body due ta remaining air bubbles. [0092] In this case, it is more preferable that the application body 14 is made transparent or translucent sa as tomake the interior application liquid visible, whereby the interior of the application body 14 can be externally observed and fully confirmed. [0093] Here, the present invention should not be limited to the above configurations of the embodiments, but various modifications and changes can be made within the scope of the present invention. For example, the application body may be formed in a tapered shape other than the sloped configuration; a plurality of delivery openings may be formed; and a clicking type liquid pressurizing mechanism may be adopted. [Industrial Applicability] [0094] The liquid applicator of the present invention is most suitably used for makeup applicators for directly applying application liquids for lip rouge, cheek rouge, eyeshadow, etc., to the human skin. Other than these, the liquid applicator of the present invention can be used for the applicators for chemical products for applying fluid chemicals, and for the applicators for applying application liquids such as adhesives, paints, etc., to the object . Further, as the application liquid, low-viscosity or high-viscosity cosmetics may be used. A high-viscosity cosmetic, for example, a cheek cream or other high internai_ water phase water-in-oil emulsified cosmetics can be applied and spread thin and broadly without the need of skill, hence the applicator can be favorably used for foundation, lotion, skincare, etc. [Description of Reference Numerals] [0095] 12 liquid pressurizing mechanism 14 application body 14a interior face of application body 14b delivery port 16 spacer 16a exterior face of spacer 16b1, 16b2 communication hole of spacer 32 clearance 32b clearance 34 application body-side projected area 36 spacer-side projected area 38 anti-rotation indentation for application body 40 communication groove of spacer 42 projection of spacer REVENDICATIONS1.
