A subdivided fixed amount distributing apparatus for aerosol containers is provided in which aerosol contents exceeding a specified amount is prevented from being used in one cycle by keeping constant in total number of injection times at all times. A structure is simplified by making it possible to eject total amount to the outside every one time by means of a fixed amount injection valve, so that damage to the distributing apparatus due to outside air temperature is prevented and movement of the distributing apparatus is made smooth when it is pushed and released. The subdivided fixed amount distributing apparatus includes a lower sleeve  18  secured to an upper end of an aerosol container  1 , a nozzle body  15  formed with a nozzle  16  communicating with a stem  4 , a rotating body  23  disposed in a rotatable manner with respect to the nozzle body  15  and the lower sleeve  18 , an annular body  34  disposed at an upper side of the rotating body  23 , a pushing body  45  pushing the stem  4 , and an upper sleeve  37  secured to the lower sleeve  18  at a lower end thereof, in which pushing operation of the stem  4  enables a fixed amount injection of the aerosol contents and positional movement of a fitting piece  28  while pushing operation of the stem  4  and positional movement in the same direction of the fitting piece  28  are disabled by hitting the fitting piece  28  on an upper end surface of a lower projection  21  after positional movement by pushing operation of predetermined times.

Full Description:
TECHNICAL FIELD 
       [0001]    This invention relates to a subdivided fixed amount distributing apparatus for aerosol containers allowing only use of a fixed amount of aerosol contents such as medical products, hair care products, and cosmetic products in which a use amount for one cycle, such as e.g., one day, several days, or one week, is restricted. 
       BACKGROUND TECHNOLOGY 
       [0002]    Some aerosol contents contained in an aerosol container, such as medical products, hair care products, and cosmetic products may be used directly for human bodies. If such aerosol contents are used exceedingly in an amount more than a prescribed use amount, however, such use may cause harmful effects on human beings, or may result in wasteful use. As disclosed in Japanese Unexamined Patent Publication No. 2001-232249, a subdivided amount distributing apparatus for aerosol containers has been developed in which the apparatus capable of spraying a prescribed fixed amount usable in a certain period multiple times is connected to a stem of an aerosol container and disposed at an exterior of the aerosol container. 
         [0003]    This subdivided amount distributing apparatus for aerosol containers is formed with a fixed amount chamber and a fixed amount injection valve, respectively, in the apparatus, and the aerosol contents of a fixed amount are introduced from the aerosol container main body into the fixed amount chamber and stored therein. The interior of the fixed amount chamber is normally pressurized with a piston, and the aerosol contents contained in the fixed amount chamber are injected multiple times in a subdivided manner through the fixed amount injection valve. Fixed amount injection during a prescribed period is allowed by injection of a fixed amount one or more times, thereby bringing advantages realizing distribution of aerosol contents suitable for medical products, hair products, and cosmetic products, which are otherwise not favorable when used in an amount of a prescribed amount or more or used in a wasteful manner. 
       SUMMARY OF THE INVENTION 
     Problems to be Solved by the Invention 
       [0004]    However, the subdivided amount distributing apparatus described in Japanese Unexamined Patent Publication No. 2001-232249 is disposed at an exterior of the aerosol container. Therefore, the prescribed amounts in proportion to one day or one week are stored in the fixed amount chamber in the prescribed period in a state that the aerosol contents are pressurized, so that the volume of the aerosol contents may be expanded due to changes of the outer temperature in some occasions, and so that the distributing apparatus disposed at the exterior of the aerosol container may be damaged. Because the contents are injected while the fixed amount chamber is pressurized by the piston, injection is made continuously upon gasification of liquid gas remaining at, e.g., a space between the piston and the fixed amount chamber even after the injection of the liquid portion of the aerosol contents is completed, thereby having a defect to inject only gasified gas. In addition, the fixed amount chamber and the fixed amount injection valve, both, are required to be built in the distributing apparatus, thereby rendering assembly of the apparatus complicated and manufacturing costs high. 
         [0005]    This invention, to solve the above problems, does not have a large fixed amount chamber able to inject the contents plural times at an exterior of the aerosol container like the subdivided fixed amount distributing apparatus for aerosol containers, but the aerosol contents can be injected after filled in the fixed amount chamber provided in the aerosol container, so that the distributing apparatus is prevented from receiving damages due to changes of the external temperature, thereby allowing the aerosol container to be used stably for a long period of time by safe use of the aerosol container, and thereby reducing the manufacturing costs. 
         [0006]    It is to be noted that the specification and claims describe the aerosol container based on a state where a bottom side thereof is positioned as the lower side, in a position such that the bottom side is set as a lower portion and a side opposite to the bottom side is set as an upper portion. 
       Means to be Solved by the Invention 
       [0007]    In an aspect of the invention, a subdivided fixed amount distributing apparatus for aerosol container includes a lower sleeve secured to a top end of the aerosol container and formed with a center opening in a center thereof, a nozzle body disposed in the center opening of the lower sleeve and formed with a nozzle bar connectable to a stem, the nozzle body formed with a nozzle communicating with the stem, a rotating body disposed at an upper side of the nozzle body and penetrating slidably the nozzle bar in a penetration bar formed on a center of the rotating body, the rotating body disposed rotatably with respect to the nozzle body and the lower bar as urged in an upper direction by a coil spring wound around the nozzle body, an annular body disposed at an upper side of the rotating body upon penetration of the penetration bar of the rotating body in an annular opening formed in a center of the annular body, a pushing body disposed at an upper side of the annular body upon penetration of penetration bar in a penetration opening, the pushing body pushing the stem via the annular body, the rotating body, and the nozzle body according to pushing down operation to open a fixed amount injection valve disposed in the aerosol container thereby allowing injection of entire amounts of aerosol contents within the fixed amount injection valve, and an upper sleeve attaching to the pushing body slidably in an up and down direction at the penetration opening, the upper sleeve secured to the lower sleeve at a lower end thereof, in which plural receiving blades whose lower end surface forms a tapered portion tapered at one corner are arranged annularly at an inner surface of the upper sleeve via insertion intervals, in which a fitting piece formed as projecting at a lower side of an outer periphery of the rotating body is rendered insertable in the insertion intervals and is disposed as facing to such the lower end surface of the sending blade as forming the tapered portion at a side of a bottom surface wall of the annular body, in which the fitting piece is pushed lower than a lower end of the receiving blade along with the annular body to push the stem to enable the fixed amount of the aerosol contents to be injected where the pushing body is pushed, in which the fitting piece pushed lower is inserted in the insertion interval along with each of inclined surfaces of the sending blade of the annular body and the receiving blade of the upper sleeve so the fitting piece as to be able to positionally move in the same direction one time, and in which pushing operation of the stem and positional movement of the fitting piece in the same direction are disabled by hitting the fitting piece on an upper end surface of an under sleeve projection formed as projecting at an upper surface of the under sleeve after the positional movement of a predetermined times according to the pushing operation of the pushing body. 
         [0008]    In this case, the pushing body may be provided with a projecting piece formed at a bottom surface thereof, contactable to a contact wall formed at a side of an outer periphery of the penetration bar of the rotating body, and wherein hitting between the fitting piece and the lower sleeve projection is releasable upon arbitrary rotation of the rotating body in association with manual rotation of the pushing body. 
         [0009]    In this case, the pushing body may be formed with a pushing projection at an upper surface thereof to be in pressurized contact with a user. 
       ADVANTAGES OF THE INVENTION 
       [0010]    This invention simplifies the mechanism to render the manufacturing costs inexpensive by enabling the whole amount of aerosol contents contained in a fixed amount chamber formed in the aerosol container main body to be injected to the exterior each time when pushing a pushing body. This invention also renders the aerosol container usable safely by preventing the distributing apparatus from receiving damages due to influences of external temperature. In addition, this invention enables the easy manufacturing of the aerosol container by simplifying the mechanism. This invention furthermore stabilizes movement of the distributing apparatus to render stable use of the aerosol container by enabling an annular body, a rotating body, and the pushing body to move stably in an up and down direction in association with pushing by the pushing body and releasing of the pushing. 
         [0011]    This invention, with the simple safe stable mechanism, has an advantage to render the aerosol container usable safely for a long time by limiting number of times in series of injections for fixed amount at one cycle and by preventing the aerosol contents from being used in an amount more than the prescribed amount, where medical products, hair care products, cosmetic products, etc. which are not suitable for use of a prescribed amount or more, are used as aerosol contents.

       DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0023]    Referring to  FIG. 1  through  FIG. 10 , a first embodiment using a hair growth agent injected plural times during one cycle use but subjecting to limitation of the whole use amount of injections during one cycle, is described hereinafter. Numeral  1  is an aerosol container made of aluminum, having an inner surface coated with polyamide-imide resin paint. As shown in  FIG. 2 , a fixed amount injection valve  3  whose top end is secured to a lid  2  is disposed in the aerosol container  1 . A stem  4  disposed in the fixed amount injection valve  3  is formed penetrating a stem gasket  5  provided at an inner surface of the lid  2 , and an orifice  6  is arranged on an outer side of the stem gasket  5  during a non-pushing state whereas the orifice  6  is arranged as inserted in a fixed amount chamber  7  during a pushing state. The orifice  6  communicates with an ejection route for the aerosol contents, formed at an upper end of the stem  4 . 
         [0024]    The fixed amount injection valve  3  is formed with the fixed amount chamber  7  and a content introduction chamber  11  via an annular partition gasket  10  in a housing  8 . The partition gasket  10  comes in close contact with the outer periphery of the stem  4  as shown in  FIG. 3  to disconnect the fixed amount chamber  7  from the content introduction chamber  11 , and the orifice  6  of the stem  4  is introduced into the interior of the fixed amount chamber  7  where the stem  4  is pushed and penetrated into the partition gasket  10  during use in a manner of up side down, so that the aerosol contents contained in the fixed amount chamber  7  only is discharged in the whole amount to the exterior through the ejection route of the stem  4 . Upon release of pushing operation to the stem  4 , as shown in  FIG. 2 , the stem  4  is returned to the original position to separate the partition gasket  10 , thereby communicating the fixed amount chamber  7  with the content introduction chamber  11 , and thereby introducing the aerosol contents contained in the content introduction chamber  11  into the fixed amount chamber  7 . 
         [0025]    The content introduction chamber  11  is normally in communication with an interior of the aerosol container  1  through an introduction route  13  provided between the outer periphery of the housing  8  and an outer sleeve  12  of the housing  8 . It is to be noted that in this embodiment the fixed amount injection valve  3  thus formed is used but the structure is not limited as far as a fixed amount injection valve  3  used in other embodiments can inject the aerosol contents of a prescribed amount to the exterior by pushing operation of the stem  4  and is contained in the interior of the aerosol container  1 . 
         [0026]    As shown in  FIG. 2 , a nozzle body  15  projectingly forming an annular nozzle bar  14  is formed as connecting to the nozzle bar  14 , thereby communicating a nozzle  16  formed at an upper end of the nozzle bar  14  with the ejection route of the stem  4 . A lower sleeve  18  is secured to an upper end of the aerosol container  1  by rendering stem  4  connected to the nozzle body  15  through a center opening  20  formed in a center of the lower sleeve  18 . This nozzle body  15  is disposed so as to be movable an up and down direction in the center opening  20  of the lower sleeve  18 . As shown in  FIG. 1 , furthermore, one part of the lower sleeve  18  is projectingly formed as a lower sleeve projection  21  in an axial direction at an outer periphery side of the upper surface of the lower sleeve  18 . 
         [0027]    A rotating body  23  is disposed through a coil spring  22  onto an upper side of the nozzle body  15  thus disposed and is urged by the coil spring  22  in an upward direction. The rotating body  23  is formed by providing a cylindrical penetration bar  26  in an axial direction to a center of a base  25  having an annular wall  24  formed as projecting at an outer periphery thereof, and the nozzle bar  14  of the nozzle body  15  penetrates into the penetration bar  26 . 
         [0028]    The penetration bar  26  is formed to have an inner diameter thereof larger than an outer diameter of the nozzle bar  14  so as to be slidable in up, down, and peripheral directions along an outer periphery of the nozzle bar  14  in a case of penetration of the nozzle bar  14  into the penetration bar  26 . The rotating body  23  is in a rotatably movable state independently from the nozzle body  15 . As shown in  FIG. 3 , an outer diameter of the base  25  is set to smaller than a diameter of the center opening  20  of the lower sleeve  18  to allow the rotating body  23  to move in the center opening  20  of the lower sleeve  18 . 
         [0029]    As shown in  FIG. 1 , a contact wall  27  is formed between an outer circumferential surface of the penetration bar  26  and an inner circumferential surface of the annular wall  24  while a fitting piece  28  is formed on a flat surface flush with the contact wall  27  as projecting from an outer circumferential surface of the annular wall  24  to an exterior. On an outer circumference of the contact wall  24 , two fitting short pieces  30  shorter than the outfitting piece  28  are formed other than the fitting piece  28  on the outer circumferential surface of the annular wall  24  as projecting in a manner that intervals between the fitting piece  28  and the two fitting short pieces  30  are equal to each other. Upper end surfaces of the fitting piece  28  and the two fitting short pieces  30  have tapered surfaces  31 ,  32  taped at one side in the same direction, respectively. 
         [0030]    The annular body  34  provided with the annular opening at the center thereof is disposed on an upper side of the rotating body  23  such that the penetration bar  26  of the rotating body  23  is penetrated in the annular opening  33  and that a bottom surface wall  35  is in contact with the upper end surface of the annular wall  24  of the rotating body  34 . As shown in  FIG. 1 , a plurality of blades  36  having a lower end as a tapered portion in a letter V shape are annularly formed in a projecting manner on an outer periphery of the bottom wall  35  of the annular body  34 . 
         [0031]    As shown in  FIG. 9 , the annular body  34  is formed in a manner that sending blades  36  are located at an axial center side with respect to receiving blades  38  of an upper sleeve  37  and a lower sleeve projection  21  of a lower sleeve  18  at the time of assembly. As shown in  FIG. 5 , the annular body  34  is also disposed in a manner that a vertex  40  on a projecting side of the sending blade  36  is located at an approximate center in an insertion interval  41  of the upper sleeve  37 . Furthermore, as shown in  FIG. 1 , four outer peripheral projecting portions  42  are formed with equal intervals in a projecting manner on an outer periphery of an upper surface of the annular body  34 . 
         [0032]    A pushing body  45  in which the penetration bar  26  is penetrated in the penetration opening  44  formed in a center of a substrate  43  in a circular shape is disposed at an upper side of the annular body  34 , and four bar-shaped pushing projections  46  having an arc-shaped front end are formed on an upper surface of the substrate  43  of the pushing body  45  as projecting in an axial direction. It is to be noted that the four pushing projections  46  in a shape as shown in  FIG. 1  are formed in this embodiment but may be in any other shape capable of pushing a head of human being and the number of the pushing body is not especially limited. 
         [0033]    A projecting piece  48  is formed on one location of a bottom surface  47  of the substrate  43  as projecting in a bottom-surface-axial direction. This projecting piece  48  is provided to rotate the rotating body  23  in a proceeding direction by putting the projecting piece  48  in contact with the contact wall  27  so that the fitting piece  28  is backed to an original position at the time of starting use of subsequent cycle after completion of use of one cycle. Other than the projecting piece  48 , a plurality of bottom projections  50  in a semispheric shape are annularly formed on the bottom surface  47  of the substrate  43 . The bottom projections  50  are provided to reduce frictional resistance which is caused between the annular body  34  and the pushing body  45  at the time of rotation of the pushing body  45 . 
         [0034]    As shown in  FIG. 2 , the pushing projections  46  of the pushing body  45  pierce through a piercing opening  51  of the upper sleeve  37 . A lower end of the upper sleeve  37  is inserted in a space between an inner wall  52  and an outer wall  53  of the lower sleeve  18  to engage an engagement projection  54  formed on an inner circumferential surface of the outer wall  53  of the lower sleeve  18  with an engagement receiver  55  formed on an outer circumferential surface thereof so that the upper sleeve  37  is secured to the lower sleeve  18 . The pushing projections  46  of the pushing body  45  are disposed as movable in an up and down direction dependently from the upper sleeve  37  while being urged by the coil spring  22  inside the piercing opening  51  of the upper sleeve  37  thus secured. 
         [0035]    Furthermore, the receiving blades  38  having a lower end as an inclined surface  56  inclined at one side are formed as projecting in a bottom-end-axial direction on a ceiling surface of an inner wall of the upper sleeve  37 , as shown in  FIG. 1 . This inclined surface  56  is formed in a direction opposite to the tapered surfaces  31 ,  32  of the fitting piece  28  and the fitting short pieces  30 . As shown in  FIG. 9 , the fifteen receiving blades  38  of the upper sleeve  37  are continuously formed in an annular manner with insertion intervals  41  capable of fitting the fitting piece  28  and the fitting short pieces  30  of the rotating body  23  while a flat portion  58  at which the receiving blades  38  are not continuously formed is formed at one location of the upper sleeve  37 . 
         [0036]    The bottom wall surface  57  for connecting the inner wall  52  to the outer wall  53  is formed between the inner wall  52  and the outer wall  53  of the lower sleeve  18  while engagement recesses  60  are formed at three locations with equal intervals on the bottom wall surface  57 . On the lower end of the upper sleeve  37 , engagement convexes  61  are formed as projecting in an axial direction at three locations corresponding to the engagement recesses  60 , respectively. The upper sleeve  37  is connected to the lower sleeve  18  in a rotatably immovable manner upon engagement of the engagement convexes  61  with the engagement recesses  60 , so that the upper sleeve  37  and the lower sleeve  18  can be positioned to right locations. As shown in  FIG. 5 , it is therefore possible to easily dispose the flat portion  58  of the upper sleeve  37  on a location corresponding to the lower sleeve projection  21  of the lower sleeve  18 . 
         [0037]    With the structure thus described, to perform subdivide fixed amount distributing injection, the tapered surface  31  of the fitting piece  28  is first disposed at a lower end surface of the sending blade  36  in a state where a side surface of the fitting piece  28  in a proceeding direction as indicated by an arrow in full line shown in  FIG. 5  is in contact with a side surface of a first receiving blade  62  before starting the subdivide fixed amount distributing injection. In the same manner, the two fitting short pieces  30  are respectively disposed at the lower end surfaces  63  of the sending blades  36 . The aforementioned disposal is made by assembling the rotating body  23  and the annular body  34  at the time of manufacturing, in a manner to dispose the fitting piece  28  and the fitting short pieces  30  in the above manner. In this bout, the fixed amount chamber  7  and the content introduction chamber  11  formed at the fixed amount injection valve  3  are in a communicating state, as shown in  FIG. 2 , and a fixed amount of the aerosol contents is contained in the fixed amount chamber  7 . 
         [0038]    Next, the aerosol container  1  is made upside down, and as shown in  FIG. 3 , the pushing body  45  is pushed in a bottom direction of the aerosol container  1  in opposing to urging force of the coil spring  22  while rendering the pushing projections  46  of the pushing body  45  in contact with an injection target portion  64  such as a head of human being. At this time, this pushing operation of the pushing projections  46  can give massage effects to the injection target portion  64 . 
         [0039]    Since this pushing operation renders the annular body  34  move in a bottom direction, the fitting piece  28  and the fitting short pieces  30  disposed at the lower end surfaces  63  of the sending blades  36  of the annular body  34  move along with the sending blades  36 , so that the sending blades  36 , the fitting piece  28 , and the fitting short pieces  30  move to a side of the bottom with respect to the receiving blades  38  at the time that the pushing body  45  is pushed up to the limit, as shown in  FIG. 6 . 
         [0040]    At the same time, the nozzle body  15  and the stem  4  move toward the bottom of the aerosol container  1  as shown in  FIG. 3 . Therefore, the orifice  6  located on an outer side of the fixed amount chamber  7  during a non-pushing state is moved and disposed in an interior of the fixed amount chamber  7 , thereby being put in contact with the aerosol contents inside the fixed amount chamber  7 . Furthermore, the stem  4  pierces through the partition gasket  10  disposed between the content introduction chamber  11  and the fixed amount chamber  7 , so that the outer periphery of the stem  4  comes in close contact with the partition gasket  10 , thereby disconnecting the communication between the content introduction chamber  11  and the fixed chamber  7 . Therefore, the whole amount of the aerosol contents contained in the fixed amount chamber  7  is injected out of the nozzle  16  through the orifice  4  and the introduction route of the stem  4 . 
         [0041]    When the pushing operation of the pushing body  25  is stopped after the whole amount of the aerosol contents contained in the fixed amount chamber  7  is injected, the pushing body  45  is moved by the urging force of the coil spring  22 , in a direction opposite to the bottom of the aerosol container  1 . The nozzle body  15  and the stem  4  are accordingly backed to the original positions by the urging force of the stem spring  65 , and thus the orifice  6  is disposed at the outer side of the fixed amount chamber  7  again. Upon release of the pushing operation, the sending blades  36 , the fitting piece  28 , and the fitting short pieces  30  are moved in the same direction as the pushing body  45 , by resilience of the coil spring  22  and the stem spring  65 , so that the tapered surfaces  31 ,  32  of the fitting piece  28  and the fitting short pieces  30  hit, during moving operation, inclined surfaces  56  of the receiving blades  38 , respectively, as shown in  FIG. 2 . 
         [0042]    The fitting piece  28  and the fitting short pieces  30  slide into the insertion intervals  41  next to the insertion intervals  41  at which the fitting piece  28  and the fitting short pieces  30  were located before the pushing operation of the pushing body  45 , while positionally moving in a proceeding direction along with the inclined surfaces  56  of the receiving blades  30 , respectively. The fitting piece  28  and the fitting short pieces  30  are respectively disposed at the lower end surfaces  63  of the sending blades  36  arranged inside those insertion intervals  41 , as indicated by a dashed line in  FIG. 5 . In this bout, since the two fitting short pieces  30  positionally moves in an up and down direction and in a proceeding direction at the same time along with the fitting piece  28 , the rotating body  23  can be stably moved in a top and down axis direction while the substrate  25  of the rotating body  23  is kept in a horizontal position. Thus, the penetration bar  26  can be moved along the outer periphery of the nozzle bar  14  in an up and down direction smoothly during a pushing state and release of pushing state. 
         [0043]    As shown in  FIG. 9 , the outer peripheral projecting portions  42  formed as projecting on the outer periphery of the annular body  34  are disposed as inserted between the upper sleeve  37  and the receiving blades  38 , and move in an up and down direction along with the receiving blades  38  at both adjacent sides during a pushing state and release of pushing state, so that the annular body  34  moves in an up and down direction only and cannot move in a circumferential direction. 
         [0044]    Upon release of pushing operation of the pushing body  45 , the rotating body  23  positionally moves in a proceeding direction in association with movement of the fitting piece  28  while the annular body  34  moves in an up and down direction only independently from positional movement of the rotating body  23 , so that the sending blades  36  of the annular body  34  can be stably moved at all times in an up and down direction at the time of positional movement of the fitting piece  28 . The movement of the rotating body  23  and the annular body  34  thus described enable the distributing apparatus to be smoothly operated in injecting the fixed amount of the aerosol contents. With the steps described above, the fixed amount injection of the first time is completed. The substantially same steps are performed upon pushing operation of pushing body of the second time to inject the fixed amount of aerosol contents. 
         [0045]    As described above, the fitting piece  28  moves sequentially between the insertion intervals  41  upon repeat of pushing and stop of pushing of the pushing body  45  at each time of the fixed amount injection. Where the pushing body  45  is further pushed after repeating the movement fifteen times in total, the fitting piece  28  slightly moves toward the bottom along with the sending blade  36  and thereafter hits the lower sleeve projection  21  formed as projecting on the lower sleeve  18 , as shown in  FIG. 4  and  FIG. 8 . 
         [0046]    The nozzle body  15  and the stem  4  thus cannot be pushed any further toward the bottom of the aerosol container  1 , and the fixed amount injection valve  3  is not opened in this state, so that the aerosol contents cannot be injected. At this point, use of the aerosol container  1  for one cycle is completed. Therefore, the aerosol contents cannot be injected even where the pushed body  45  is continuously pushed in such a state that use of one cycle is completed, so that the aerosol contents can be prevented from being used more than the prescribed amount. 
         [0047]    The next use cannot be subsequently started in a state where the use of one cycle is completed as describe above, and the fitting piece  28  hits the lower sleeve projection  21  as shown in  FIG. 8 , so that the rotating body  23  cannot be further rotated in a proceeding direction. Thus, the following steps are required to start the subsequent use of the next cycle. First, the pushing body  45  is rotated in a non-pushing state, until the projecting piece  48  of the pushing body  45  comes in contact with the contact wall  27  of the rotating body  23 . Where the projecting piece  48  comes in contact with the contact wall  27  as shown in  FIG. 9 , the pushing body  45  is further rotated in the same direction in a state where the projecting piece  48  is in contact with the contact wall  27 . 
         [0048]    Thus, the rotating body  23  rotates together with the pushing body  45  as shown in  FIG. 10 , and the fitting piece  28  located on the lower end surface  63  of the sending blade  36  corresponding to the lower sleeve projection  21  crosses over the vertex  40  on a projecting side of a subsequent sending blade  36  located next to the aforementioned sending blade  36  in a proceeding direction as indicated by a dashed-dot line shown in  FIG. 5 , thereby being disposed at a lower end surface  63  of the subsequent sending blade  36  in a state where the side surface of the fitting piece  28  is in contact with the side surface of the first receiving blade  62  as indicated by a full line shown in  FIG. 5 . 
         [0049]    Each of the fitting pieces  30  also crosses over the vertex  40  on the projecting side of the subsequent sending blade  36  in the substantially same manner, thereby being disposed at the next fitting position. In the meanwhile, as shown in  FIG. 9  and  FIG. 10 , formation lengths of a fifth receiving blade  66  and an eleventh receiving blade  67  are set to shorter than the other receiving blades  38  in order to prevent the rotating body  23  from becoming rotatably immovable by coming in contact with the corresponding fifth receiving blade  66  and the eleventh receiving blade  67  at the time that the fitting short piece  30  crosses over the vertex  40  of the sending blade  36   
         [0050]    The pushing body  45  can rotate in a circumferential direction independently from the annular body  34  or the rotating body  23  as described above, thereby enabling the projecting piece  48  of the pushing body  45  to rotate freely within a range such that the projecting piece  48  does not come in contact with the contact wall  27  of the rotating body  23 . Therefore, the rotating body  23  rotates in a proceeding direction by positional movement of the fitting piece  28  during a pushing operation of the pushing body  45  but the pushing body  45  is formed separately from the rotating body  23 , thereby not necessarily rotating in association with this rotation of the rotating body  23 . 
         [0051]    Therefore, even where the pushing body  45  is rendered to rotate in a proceeding direction somewhat in a case of performing injection by pushing the pushing projection  45 , such a case is not caused, that the rotating body  23  moves between the plurality of insertion intervals  41  in association with rotation of the pushing body  45  as long as the projecting piece  48  of the pushing body  45  does not come in contact with the contact wall  27  of the rotating body  23 . Furthermore, even where only the pushing body  45  is rendered to rotate in mistake in a state where the injection is not performed, such a problem can be avoided, that the fitting piece  28  positionally moves into the subsequent insertion interval  41  certainly in association with the rotation of the pushing body  45 , as long as the projecting piece  48  does not come in contact with the contact wall  27 , since the pushing body  45  rotates independently from the rotating body  23 . Therefore, it becomes possible to certainly stabilize the whole injection amount of aerosol contents to be injected in use of one cycle. 
         [0052]    As shown in  FIG. 1 , the bottom projections  50  are formed at the bottom surface  47  of the pushing body  45 , thereby reducing frictional resistance which is caused between the upper surface of the annular body  34  and the bottom surface  47  of the pushing body  45  at the time of rotation of the pushing body  45 , so that the pushing body  45  can be rendered to rotate more smoothly. 
         [0053]    It becomes possible to inject again the fixed amount of aerosol contents fifteen times in total by pushing continuously the pushing body  45  after placement of the fitting piece  28  and the fitting short pieces  30  to locations for the use of the first one cycle, as described above. Therefore, the injection amount of the aerosol contents usable in a prescribed period can be limited to a prescribed amount while risks that aerosol contents are otherwise used more than the prescribed can be avoided since a special procedure is required to restart subsequent use for the next cycle after completion of the use for the first cycle, in which the pushing body  45  is manually rotated in a proceeding direction in a non-pushing state. 
         [0054]    For example, where the head of human being is the injection target portion  64 , the aerosol contents of the prescribed amount can reach the whole head of human being entirely by injections fifteen times with changing the injection location at each injection. It is to be noted that the total injection number for one cycle is limited to fifteen times in this embodiment but may be set more or less than fifteen times by adjustment of the number of the receiving blades  38  of the upper sleeve  37  and the sending blades  36  of the annular body  34  in other embodiments.
