  In the present embodiment, as shown in FIG. 1, the mobile body feeding container is a liquid cosmetic extrusion container that contains a liquid cosmetic 10 that is a liquid and appropriately pushes out and uses the contained liquid cosmetic 10. .

  And this mobile body delivery container is comprised as the container main body 1, the mobile body 2, and the click mechanism 3 as shown in the figure.

  Hereinafter, each of these components will be described in more detail.

(1) Container body 1
As shown in FIG. 1, the container body 1 is made of plastic (for example, transparent plastic) and is formed in a hollow cylindrical shape (for example, cylindrical shape). And the container main body 1 has the front-end | tip wall part 11 which forms each surface shape of the outer surface and inner surface which incline with respect to an axis at the front-end | tip, as shown in FIG.1 and FIG.2, This front-end | tip wall part 11, a discharge hole 11a (for example, a plurality of discharge holes 11a) for discharging the liquid cosmetic 10 out of the container body 1 is provided.

  In addition, the front-end | tip wall part 11 forms the surface shape of the outer surface which inclines with the inclination suitable for the application | coating with respect to to-be-coated parts, such as the skin surface, for example (refer these drawings).

  As shown in FIG. 1, a female screw 12 is formed inside the container body 1, and by screwing a male screw 21 a of the moving body 2 described later into the female screw 12, the moving body 2 is screwed. It is possible to feed out in the axial direction.

  As shown in FIGS. 1 to 3, the container body 1 includes an outer cylinder 1 a and an inner cylinder 1 b that is attached to the outer cylinder 1 a and has a female screw 12 formed therein.

  Specifically, in the inner cylinder 1b, an annular recess 41 and an annular protrusion 42 formed outside the rear end engage with an annular protrusion 51 and an annular recess 52 formed inside the rear end of the outer cylinder 1a. A protrusion 43 (for example, a plurality of protrusions) formed in the axial direction on the outside of the inner cylinder 1b engages with a groove 53 (for example, a plurality of grooves) formed in the knurl shape in the axial direction inside the outer cylinder 1a. Thus, the outer cylinder 1a is mounted so as not to rotate about the axis and to move in the axial direction. As a result, the outer cylinder 1a and the inner cylinder 1b are fixed integrally.

  In this embodiment, as shown in FIGS. 1 and 2, the outer cylinder 1 a has a tip wall portion 11 that forms each surface shape of an outer surface and an inner surface inclined with respect to the axis at the tip. The tip wall portion 11 has a discharge hole 11a.

  Here, although not shown, the discharge hole 11a of the tip wall portion 11 is blocked by a stopper so that the liquid cosmetic 10 does not leak. In addition, instead of the stopcock, a seal coated with an adhesive that can be removed immediately before use by the user is attached to the outer surface of the tip wall portion 11 before filling the liquid cosmetic 10, and the discharge hole 11a is formed. You may make it obstruct | occlude.

  Moreover, as shown in FIG.1 and FIG.3, the 2nd click tooth | gear part 32 is formed in the inner cylinder 1b so that it may protrude inside from the inner periphery of the side wall.

The reason why the second click tooth portion 32 is required to be formed in the inner cylinder 1b in this way is that the second click tooth portion 32 which is one of the components of the click mechanism 3 is provided by a separate independent component. This is because, by configuring as a part of the container main body 1, a movable body feeding container having a simple configuration with a smaller number of parts while maintaining the click function. Therefore, if it plays such a role, instead of the container main body 1 consisting of the outer cylinder 1a and the inner cylinder 1b in the present invention, a container main body as a single cylindrical body having a tip wall portion, a bar-shaped cosmetic material It is also possible to use a container body or other container body.
Specifically, a container body made of a plastic such as polyethylene terephthalate (PET), polypropylene (PP), or polycyclohexylene dimethyl terephthalate (PCT) is preferable.

  As shown in FIG. 1, the container body 1 has a liquid makeup for containing the liquid cosmetic 10 adjacent to the front side of the moving body housing portion 13 for housing the distal end side portion of the moving body 2. It has a charge storage part 14.

  That is, the liquid cosmetic container 14 or the movable body container 13 is configured to change the length dimension in the axial direction as the movable body 2 is drawn out by a screwing operation (see FIG. 1).

  As shown in the figure, the liquid cosmetic container 14 includes a tip wall 11 inclined with respect to the axis, a cylindrical (for example, cylindrical) side wall, and a piston 22 for extruding the liquid cosmetic 10. Is formed.

(2) Moving body 2
As shown in FIGS. 1 and 4, the movable body 2 is made of plastic (for example, transparent plastic), is formed in a substantially rod shape, and a male screw 21 a that is screwed into the female screw 12 is formed outside. It is configured as

  That is, the moving body 2 is configured such that the male screw 21a is screwed to the female screw 12 and is mounted on the container body 1 so as to be rotatable about the axis and movable in the axial direction. By repeating the operation of screwing into the container 1, it can be drawn out in the axial direction. As a result, the liquid cosmetic 10 accommodated in the liquid cosmetic container 14 can be transferred to the container through the discharge hole 11 a of the tip wall 11. It can be pushed out of the main body 1 (see FIG. 5).

The fact that the moving body 2 is required to be fed out in the axial direction by being screwed into the container body 1 is realized by relative rotation in which the moving operation of the moving body 2 is performed by providing separate parts such as a sleeve. This is because the moving body 2 itself is directly screwed into the container body 1 to realize a moving body feeding container having a simple configuration with a smaller number of parts while maintaining the click function. . Therefore, if it plays such a role, instead of the moving body 2 in the present invention, it is possible to use a core chuck or other moving body for bar-shaped cosmetics.
Specifically, a moving body made of plastic, elastomer, or the like is preferable.

  Specifically, as shown in FIGS. 1 and 4, the moving body 2 has a piston shaft having an external thread 12 and an operation portion 21 b for performing a rotation operation around the axis on the rear end side. 21 and a piston 22 that is connected to the tip of the piston shaft 21 so as to be rotatable about the axis, and is slidably inserted into the container body 1 while being in watertight contact with the inner peripheral surface of the container body 1. It has a bell shape that tapers toward the tip.

  In the present embodiment, as shown in these drawings, a first click tooth portion 31 is formed on the piston shaft 21 so as to protrude outward from the outside and extend in the axial direction.

  An annular recess 61 and an annular protrusion 62 for engaging with an annular protrusion 71 and an annular recess 72 provided in the middle region of the space 32 a of the piston 22 are provided in the tip region of the piston shaft 21. It has been.

  The reason why the first click tooth portion 31 is required to be formed on the piston shaft 21 is that the first click tooth portion 31 which is the other component of the click mechanism 3 is provided by a separate independent component. By configuring as a part of the mobile body 2 without, the mobile body feeding container having a simple configuration with a smaller number of parts while maintaining the click function. Therefore, if it plays such a role, instead of the moving body 2 consisting of the piston shaft 21 and the piston 22 in the present invention, as a moving body or an integrated article having a head corresponding to the piston 22, Alternatively, a movable body for bar-shaped cosmetics composed of a core chuck and a screw rod or other movable body may be used.

  On the other hand, the piston 22 is composed of an elastic body such as silicon rubber (for example, a soft elastic body) (see FIG. 5).

  Here, as the elastic body, in addition to silicon rubber, thermosetting materials by compression molding such as nitrile rubber (NBR), ethylene propylene rubber (EPR), butyl rubber (IIR), polyurethane elastomer (TPU), polyolefin elastomer (TPO), thermoplastic elastomers by injection molding, such as polyester elastomer (TPEE), and thermoplastic plastics by injection molding, such as low density polyethylene (LDPE), linear low density polyethylene (LLDPE), etc. Is possible.

  Such a piston 22 can be elastically deformed following the inclined inner surface when pressed against the tip wall 11 at the time of maximum advance (see FIG. 5).

  In addition, as shown in FIGS. 1 and 4, the piston 22 has a space 22 a for increasing the elastic deformation performance inside thereof.

  An annular convex portion 71 and an annular concave portion 72 for engaging with the annular concave portion 61 and the annular convex portion 62 provided at the tip end portion of the piston shaft are provided in the middle region of the space 22a.

  Such a piston 22 can be elastically deformed by following the inclined inner side surface more simply when it is pressed against the tip wall portion 11 at the time of maximum advance than when it is simply made of an elastic body. (See FIG. 5).

  That is, according to such a piston 22, it is possible to prevent the liquid cosmetic 10 from remaining in the tip region of the liquid cosmetic container 14 surrounded by the side wall of the tip wall 11 and the tip wall 11. As a result, it is possible to provide an economical bar-shaped cosmetic supply container that does not have any remaining use (see FIG. 5).

(3) Click mechanism 3
The click mechanism 3 gives a click feeling in synchronization with the relative rotation of the container body 1 and the moving body 2, protrudes from the outside of the moving body 2 as shown in FIG. 6, and extends in the axial direction. A first click tooth portion 31 formed so as to extend and an adjacent region 32a which is formed to protrude inward from the inner periphery of the side wall of the inner cylinder 1b as shown in FIGS. 7 to 9 are provided. Thus, the second click tooth portion 32 that can be bent outward is provided.

  The click mechanism 3 in the present embodiment also includes a ratchet mechanism that restricts the forward and backward movement of the moving body 2 only in the forward or backward direction by restricting relative rotation of the container body 1 and the moving body 2 in one direction. Yes. Specifically, the click mechanism 3 is configured to restrict the relative rotation of the container body 1 and the moving body 2 only in the direction in which the moving body 2 is screwed into the container body 1.

  With such a click mechanism, it is possible to considerably increase the added value of the product, and as a result, it is possible to more appropriately respond to consumer needs that place importance on the portability and usability of the product. Yes.

  That is, the first click tooth portion 31 gradually moves the second click tooth portion 32 when the movable body 2 rotates in the direction in which the movable body 2 is screwed into the container main body 1 (the illustrated arrow direction in FIG. 10A). And has a cross-sectional shape that can be bent outward (see FIG. 10A), and the direction opposite to the direction in which the movable body 2 is screwed into the container body 1 (FIG. 10B) The second click tooth portion 32 has a cross-sectional shape in which the second click tooth portion 32 cannot be bent outward (see FIG. 10B).

  On the other hand, when the second click tooth portion 32 rotates in the direction in which the movable body 2 is screwed into the container body 1 (the direction indicated by the arrow in FIG. 10A), the first click tooth portion 31 climbs. And has a cross-sectional shape in which an inclined surface that can be overcome is formed (see FIG. 10A), and the direction opposite to the direction in which the movable body 2 is screwed into the container body 1 (FIG. 10B). ), The first click tooth portion 31 has a cross-sectional shape that cannot be climbed over (see FIG. 10B).

  Here, as shown in FIGS. 8 and 9, the second click tooth portion 32 is configured to have a U shape in a side view, and is provided with a notched adjacent region 32 a in the circumferential direction. It is formed in the shape of the tongue piece extended in this, and is enabled to bend outside.

  In the case where the click mechanism 3 is not provided as a separate and independent part by the second click tooth part 32 as described above but is configured as a part of the original component of the moving body feeding container, the first click tooth part 31 and It is possible to smoothly repeat the engagement and release of the second click tooth portion 32, thereby ensuring a sufficient click function.

  In addition, it is not restricted to this, Regardless of which of the 1st click tooth part 31 and the 2nd click tooth part 32 has elasticity, it was notched like the modification shown in FIG. You may employ | adopt the 1st click tooth | gear part 81 enabled to be bent inward by providing the adjacent area | region 81a (In the same figure, the code | symbol 8 has shown the click mechanism in this modification. ).

  A space 32b that allows the second click tooth portion 32 to bend outward is secured outside the second click tooth portion 32 and inside the outer cylinder 1a.

  That is, by such a click mechanism 3, the first click tooth portion 31 is engaged with the second click tooth portion 32, whereby the relative rotation between the container main body 1 and the movable body 2 is changed. It is possible to regulate only in the direction of screwing in.

  Here, the 1st click tooth part 31 is formed in the fixed area of the axial direction of the mobile body 2 so that the mobile body 2 can engage with the 2nd click tooth part 32 in any position of the container main body 1. (See FIG. 6).

  Thus, the first click tooth portion 31 is required to have a certain length dimension because the click mechanism 3 is not provided as a separate and independent part but as a part of the original component of the moving body feeding container. In the case of configuring, by preventing the engagement state of the first click tooth portion 31 and the second click tooth portion 32 from being released regardless of the position of the movable body 2 in the container body 1, the number of parts is reduced. This is because the movable body feeding container has a simple configuration and can hold the click function. Therefore, if it plays such a role, instead of the first click tooth portion 31 consisting of a plurality of protrusions in the present invention, it is related to the one consisting of a single protrusion, the second click tooth portion. It is possible to use a first click tooth portion other than that provided intermittently as long as the combined state is not released.

  As described above, in the mobile body feeding container according to the present embodiment, the first click tooth portion 31 that is one of the components of the click mechanism 3 is formed on the mobile body 2 and the second is the other. The click tooth portion 32 of the click body 32 that can be bent outward is formed on the side wall of the container main body 1, and the first is independent of the connection state of the movable body 2 and the container main body 1. The click tooth portion 31 has a length dimension that engages with the second click tooth portion 32.

  Therefore, according to such a moving body feeding container, a simple configuration is realized with a smaller number of parts while maintaining a click function that allows the user to sense the moving state or the returning state of the moving body 2. As a result, it is possible to make products more compact and popularize trial samples, sales promotion samples, color confirmation samples, and the like.

  Therefore, according to such a mobile body feeding container, it is possible to flexibly cope with consumer needs that place importance on the portability and usability of products and the specialization tendency of product sales methods.

  Further, as in the present embodiment, if the container body 1 is composed of the outer cylinder 1a that does not form the female screw 12 and the inner cylinder 1b that forms the female screw 12 and has the second click tooth portion 32, The liquid cosmetic 10 accommodated in the outer cylinder 1a can be made to be particularly suitable for a liquid cosmetic extruding container of a type in which the liquid cosmetic 10 is pushed out by a piston 22 provided at the tip of the moving body 2.
