Description

[Technical Field]

[0001] The present invention relates to an application container. [Background technology]

[0002] There is known an applicator container that includes a container body that contains a liquid cosmetic such as concealer, nail polish, foundation, lipstick, etc., a cap that is screwed onto the opening of the container body, and an applicator that hangs down from the underside of the cap into the container body. With such an applicator container, the liquid can be applied by removing the cap and pulling out the applicator from inside the container body (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-034646 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional applicator container, when the liquid content in the container body becomes low, the applicator cannot reach the liquid content, and the liquid content remains at the bottom of the container body, making it impossible to use up the liquid.

[0005] Furthermore, when the application part is brought into contact with or close to the bottom of the container body, there is a risk that the application part may come into strong contact with the bottom of the container body depending on dimensional differences based on the size and shape of the container body and application part.

[0006] In order to solve the problems of the conventional technology described above, the present invention aims to create an application container that reduces the amount of liquid remaining in the container body, makes it possible to use up the liquid to the last drop, and makes it difficult for the application part to come into strong contact with the bottom of the container body. [Means for solving the problem]

[0007] Among the means for solving the above problems, the first means of the present invention is: an applicator container comprising: a container body containing a liquid content; a cap having a radially depressable portion and attached to a nozzle of the container body; an inner plug having a communication hole and fitted into the nozzle; a shaft member having a shaft body inserted into the container body, the cap, and the communication hole and arranged to be movable in the axial direction along the container axis; and an applicator portion provided at the lower end of the shaft member and arranged inside the container body, An extension portion is provided at the upper end of the shaft member, which is elastically deformable in the radial direction and is extendable and displaceable in the axial direction intersecting the shaft member in response to elastic deformation in the radial direction, and the extension portion is disposed in the cap at a position facing the pressed-in portion. And, When the pressed portion is pressed and released, the shaft member is moved forward and backward along the axial direction in accordance with the elastic deformation of the extension portion. It is said to be characterized by the above. In the first means of the present invention, when the pressed portion of the cap is pressed in, the shaft member extends and displaces, causing the application portion provided at its lower end to advance, and the application portion can be brought into contact with or close to the bottom of the container body, so that the remaining liquid contents in the main container can be impregnated into the application portion and removed, allowing the contents to be used up to the last drop.

[0008] The second means of the present invention is the above-mentioned first means plus the means that the extension portion is formed having a curved plate portion branched off from the upper end of the shaft body. In the above-mentioned means, when the curved plate portion is deformed radially, the shaft body extends and deforms in the axial direction that intersects with it. Therefore, by performing a pressing operation on the pressed portion and then releasing this operation, it becomes possible to freely move the shaft member and application portion forward and backward in the axial direction within the container body, making it possible to more reliably use up the content liquid to the last drop.

[0009] The third aspect of the present invention is the above-mentioned first or second aspect, plus the addition that the sealing lid provided on the barrel body is axially movable while tightly fitted into the sealing wall that forms the communicating hole of the inside plug. The above means can reliably prevent leakage of liquid during use.

[0010] The fourth means of the present invention is the above-mentioned second means plus the means in which the pressed-in portion is formed by a pair of slits formed in the outer tubular portion of the cap, and a pair of curved plate portions are arranged within the cap so as to face the pair of slits. In the above-described means, the pair of slits make it possible to recognize the position of the pressed portion and also to easily achieve elastic deformation in the pressed portion.

[0011] The fifth means of the present invention is the second means plus the additional means that the outer cylindrical portion of the cap is formed to be elastically deformable in the radial direction, and multiple curved plate portions are arranged inside the outer cylindrical portion.

[0012] In the above-described means, the outer cylindrical portion can be easily elastically deformed, thereby improving operability. [Effects of the Invention]

[0013] In the present invention, when pressure is applied to the cap, the application part can be moved back and forth within the container body even when the cap is closed, so that the liquid contents remaining at the bottom can be impregnated into the application part and used up to the last drop. Furthermore, the application part can be prevented from coming into strong contact with the bottom of the container body during operation. [Brief explanation of the drawings]

[0015] Hereinafter, embodiments of the present invention will be described. In the following description, the axial direction means the direction along the container axis O, the circumferential direction means the direction around the container axis O, and the radial direction means the direction perpendicular to the axial direction. First, an application container according to a first embodiment of the present invention will be described with reference to FIGS. The application container 1 shown in the first embodiment of the present invention is composed of a container body 10, a cap 20, an axial member 30, an inner stopper 40, and an application part 50, and the other parts except for the application part 50 are formed using a synthetic resin material. The container body 10 is integrally molded with a cylindrical mouth portion 11 having a male thread 11a formed on the outer peripheral surface thereof, a shoulder portion 12 from which the mouth portion 11 is erected, a cylindrical body portion 13 connected to the shoulder portion 12, and a bottom portion 14 provided at the lower end of the body portion 13. The body portion 13 contains liquid cosmetics such as concealer, nail polish, foundation, lipstick, etc. The external shape of the body portion 13 may be cylindrical as shown in the first embodiment, or it may be a rectangular tube or other shape.

[0016] 2 and 3, the cap 20 has a cylindrical outer tube portion 21, an inner flange 22 extending horizontally radially inward from the inner surface of the outer tube portion 21, and an inner tube portion 23 suspended from the inner edge of the inner flange 22. An internal thread 23a is formed on the inner peripheral surface of the inner tube portion 23 to be threadedly engaged with the external thread 11a of the container body 10. A pair of slits 25 constituting the pressed-in portion 21A is formed at two axially symmetrical positions on the outer tube portion 21. As shown in FIG. 1, the slit 25 is formed by a pair of parallel slits 25a extending along the axial direction, and a convex slit 25b protruding in the circumferential direction and in directions away from each other, at the intermediate portion. The portion where the pair of slits 25 face each other in the circumferential direction forms pressed-in portion 21A, and when the portion formed into a substantially circular shape by convex slits 25b (the center of pressed-in portion 21A) is pressed radially inward, pressed-in portion 21A elastically deforms with both the upper and lower end portions of the pair of parallel slits 25a as fulcrums, and can be pressed toward the inside of cap 20. Note that the pair of slits 25 function as markers that visually indicate the circumferential positions of the pair of pressed-in portions 21A on the outer circumferential surface of cap 20, allowing the user to easily grasp the positions of the pair of pressed-in portions 21A.

[0017] 3, shaft member 30 has, at the top of thin rod-shaped shaft body 31, ring-shaped extension 32 consisting of a pair of curved plate portions 32a formed by branching off shaft body 31, with top plate 33 connected to the upper end of continuing ring-shaped extension 32. Furthermore, at a lower position of the branched portion, sealing lid 34 composed of a contact ring or piston or the like formed by a radially outer edge formed to expand in diameter downwards is integrally formed.

[0018] The inside plug 40 is integrally formed with an outward flange 41 placed on the upper end of the tubular neck 11, a seal wall 42 that fits tightly against the inner circumferential surface of the tubular neck 11, and a communication hole 43 that penetrates the seal wall 42 in the axial direction, and is fitted into the tubular neck 11. The seal wall 42 that forms the communication hole 43 is integrally formed with a sliding-permitting portion 42a formed with a constant inner diameter in the upper half and a reduced-diameter portion 42b formed with a shape that tapers downward from the top to the bottom. The sealing lid 34 of the shaft member 30 is fitted into the sliding-permitting portion 42a. When the shaft body 31 moves axially, the sealing lid 34 moves together with the shaft body 31 while tightly fitting into the sliding-permitting portion 42a and maintaining a seal. The sealing lid 34 is movable within the sliding-permitting portion 42a to the boundary between the sliding-permitting portion 42a and the reduced-diameter portion 42b.

[0019] Applicator part 50 is formed from a material, such as a sponge, that is capable of shrinking and deforming and temporarily retaining the liquid content therein, and is fixed to the lower end of barrel body 31. There are no particular limitations on the size or shape of applicator part 50, but it is preferably elongated so that it can pass through communicating hole 43 of inner plug 40.

[0020] Next, the assembly of the coating container 1 having the above-mentioned configuration will be described. First, the shaft member 30 is assembled to the cap 20 . The shaft member 30 is assembled to the cap 20 by inserting the lower end having the application portion 50 into the inner cylindrical portion 23, arranging the extension portion 32 consisting of a pair of curved plate portions 32a inside the outer cylindrical portion 21, and fitting and fixing the top plate 33 to the upper end of the outer cylindrical portion 21 to seal the top surface of the cap 20. It is being done. In this state, of the curved plate portions 32a constituting the ring-shaped extension portion 32, a pair of wide portions 32c located farthest from the shaft member 30 are positioned opposite the centers of a pair of pressed portions 21A formed on the outer tube portion 21.

[0021] Next, the inner stopper 40 is set in the cylindrical mouth portion 11 of the container body 10 containing the liquid content. That is, the communication hole 43 side of the inner stopper 40 is inserted into the cylindrical mouth portion 11, the outward flange 41 is placed on the upper end of the cylindrical mouth portion 11, and the outer peripheral surface of the sealing wall 42 is fitted tightly against the inner peripheral surface of the cylindrical mouth portion 11.

[0022] Finally, as shown in Figure 4, the lower end of the shaft member 30 equipped with the applicator part 50 is inserted into the container body 10 through the communication hole 43 of the inner plug 40, and the applicator part 50 is impregnated in the liquid content. Then, the female thread 23a of the cap 20 is screwed onto the male thread 11a on the container body 10, thereby fitting the cap 20 over the tubular mouth part 11. When the cap 20 is closed, the lower end of the sealing lid 34 is in close contact with the inner circumferential surface of the sliding-permitting part 42a that forms the communication hole 43, thereby maintaining a seal that prevents leakage of the liquid content. Alternatively, the lower end of the shaft member 30 equipped with the application part 50 may be inserted into the inner plug 40 first, and then the inner plug 40 together with the shaft member 30 may be set in the nozzle 11 of the container body 10 .

[0023] Next, a method of using the application container 1 having the above-described structure will be described. (normal use) The user turns the cap 20 in the opening direction to unscrew it from the nozzle 11, then pulls up the shaft member 30 together with the cap 20, and removes the application part 50, which is immersed in the liquid contents, from the container body 10, and can then apply makeup, etc., using the liquid contents immersed in the application part 50.

[0024] (Use when remaining battery is low) The user performs a pressing operation by pressing a pair of pressed portions 21A formed on the outer cylindrical portion 21 of the cap 20 radially inward from both sides. This causes the pair of pressed portions 21A to elastically deform inward, and the central portions of the pair of pressed portions 21A press a pair of wide portions 32c constituting the extension portion 32 on the shaft member 30 radially inward. This causes the shaft member 30 to attempt to extend in the axial direction intersecting the radial direction (the pressing direction). The top plate 33 at the upper end of the shaft member 30 is fixed to the upper end of the outer cylindrical portion 21 of the cap 20 and therefore cannot extend upward. Therefore, the shaft member 30 as a whole attempts to extend downward. However, as shown in FIG. 5 , the lower end of the sealing lid 34 of the shaft member 30 slides along the inner circumferential surface of the sliding-permitting portion 42a that forms the communication hole 43, causing the shaft member 30 to extend downward. This allows the applicator part 50 provided at the lower end of the shaft member 30 to advance to a position where it approaches or comes into contact with the inner surface of the bottom part 14 of the container body 10. At this time, the seal lid 34 moves downward, and the inside of the container body 10 is set to a pressurized state.

[0025] Furthermore, when the user releases the pressure on the pair of pressed portions 21A, the sealing lid 34 is pushed upward as it attempts to return from the pressurized state to its original state, the shaft member 30 moves upward, the pair of wide portions 32c deform radially outward, and the extension portion 32 returns to its original shape before deformation, thereby returning the pair of pressed portions 21A to their original shape before pressing (see Figures 1 and 4).

[0026] By alternately performing the above-described pressing operation on the pair of pressed portions 21A and the operation of releasing the pressing operation, it is possible to freely move the shaft member 30 forward and backward to bring the applicator part 50 into contact with or close to the bottom part 14 of the container body 10, or to release the contact or closeness. Moreover, such an operation can be performed with the cap 20 in a closed state, and the content liquid remaining on the bottom part 14 can be easily and reliably impregnated into the applicator part 50 and removed, allowing the content liquid to be used up to the last drop.

[0027] Furthermore, the range within which the shaft member 30 can be extended and displaced is limited to the boundary position between the sliding allowance portion 42a and the reduced diameter portion 42b, through which the sealing lid 34 can move. Therefore, when the applicator portion 50 is brought into contact with or close to the bottom 14 of the container body 10, it is possible to prevent a problem in which the applicator portion 50 comes into strong contact with the bottom 14 of the container body 10 due to dimensional differences based on the size, shape, etc. of the container body 10 and the applicator portion 50.

[0028] Next, a second embodiment of the present invention will be described with reference to FIGS. The difference between the application container 1 shown in the second embodiment and the first embodiment is that the configuration of the cap 20 and the shaft member 30 has been changed and the pressed-in portion 21A formed by the slit 25 has been eliminated, but the other configurations and effects are the same as those of the first embodiment. The following description will focus on the differences, with the same members being assigned the same reference numerals.

[0029] As shown in Figures 7, 8, and 9(b), in the second embodiment of the present invention, the extension portion 32, which is composed of a pair of curved plate portions 32a in the first embodiment, is composed of a plurality of curved plate portions 32a (eight in this embodiment). As in the first embodiment, the curved plate portions 32a are formed integrally and branched from the upper end of the shaft body 31 constituting the shaft member 30, and a straight plate portion 32b formed parallel to the container axis O is integrally connected to the upper portion of each curved plate portion 32a. A ring-shaped connecting portion 35 is provided at the upper ends of the straight plate portions 32b, and the upper ends of the straight plate portions 32b are connected to the underside of the ring-shaped connecting portion 35 at multiple positions (eight positions in this embodiment) that are equally spaced circumferentially (45 degrees apart in this embodiment). The ring-shaped connecting portion 35 is fittable inside the upper part of the outer tube portion 21, and a top plate 33 is fittably disposed inside the ring-shaped connecting portion 35.

[0030] The outer tube portion 21 of the cap 20 does not have the slits 25 described above, but is formed thin so that it can elastically deform when pressed radially. Furthermore, two axially symmetrical positions on the inner circumferential surface of the outer tube portion 21 are provided with protruding ribs 21a extending vertically. The inner portion of the outer tube portion 21 where the protruding ribs 21a are formed is thicker than the other portions, making it less susceptible to elastic deformation. The entire surface of the outer tube portion 21, excluding the two positions where the protruding ribs 21a are formed, constitutes a pressed portion 21A that can easily elastically deform radially inward.

[0031] Here, it is preferable to decorate the outer wall of outer tube portion 21, which will become pressed portion 21A, by printing, transferring, or the like, so that the position of pressed portion 21A can be easily recognized from the outside. The decoration may be, for example, the word "PUSH" or a manufacturer's logo or product name displayed in the position that will become pressed portion 21A, with the areas other than pressed portion 21A (the two areas where protruding ribs 21a are formed) left undecorated. Alternatively, conversely, the areas other than pressed portion 21A (the two areas where protruding ribs 21a are formed) may be decorated, with the pressed portion 21A left undecorated. Particularly when applicator container 1 of the present invention is used as a cosmetic container, decorating it in the manner described above can maintain an aesthetic appearance, thereby preventing the image of the cosmetic from being damaged.

[0032] As shown in FIG. 8 , the curved plate portions 32a and straight plate portions 32b forming the extension portion 32 of the shaft member 30 are disposed inside the cap 20. At two axially symmetrical positions, convex ribs 21a are disposed between adjacent straight plate portions 32b in the circumferential direction. The convex ribs 21a support the ring-shaped connecting portion 35 connected to the upper end of the straight plate portion 32b from below, preventing the shaft member 30 from falling downward within the cap 20. The straight plate portion 32b of the extension portion 32, which continues from the curved plate portion 32a, is disposed facing the inner circumferential surface of the outer tube portion 21 and extends along the axial direction while being in contact with or close to the inner circumferential surface of the outer tube portion 21. Therefore, when the shaft member 30 is rotated in the circumferential direction within the outer tube portion 21 of the cap 20, one of the adjacent straight plate portions 32b abuts against the convex rib 21a from the circumferential direction, thereby restricting the rotation. That is, the protruding rib 21a also functions as a positioning means for restricting the rotation of the shaft member 30 in the circumferential direction and for holding it in position.

[0033] A method of using the application container as the second embodiment will now be described. Normal use is the same as in the first embodiment, so a description thereof will be omitted, and the case where the remaining amount of the liquid content in the container body 10 becomes small will be described. The user performs a pressing operation to push the pressed portion 21A of the outer tube portion 21 of the cap 20 radially inward. As a result, a portion of the outer tube portion 21 that forms the pressed portion 21A elastically deforms inward, and the linear plate portion 32b, which is located at a position corresponding to the elastically deformed portion, is pressed radially inward, causing the shaft member 30 to attempt to extend and displace in the axial direction that intersects with the radial direction (the pressing direction). Therefore, as in the first embodiment, the shaft member 30 advances downward, allowing the applicator portion 50, which is provided at the lower end of the shaft member 30, to approach or come into contact with the bottom portion 14 of the container body 10, thereby allowing the content liquid to be used up to the last drop.

[0034] Next, a modification of the second embodiment will be described with reference to FIGS. The applicator container 1 shown in the modified example differs from the second embodiment in that the outer cylinder is made of a soft material having high flexibility, but other configurations and effects are the same as those of the second embodiment. Therefore, the following description will focus on the differences from the second embodiment, and the same members will be assigned the same reference numerals.

[0035] As shown in FIG. 10 , the cap 20 shown in the modified example includes a cylindrical outer tube portion 21 made of a soft material such as silicone rubber. The entire outer peripheral surface of the outer tube portion 21 functions as a pressed-in portion 21A. The upper end of the outer tube portion 21 is fitted and locked to an engagement portion 35a provided on the lower surface of a ring-shaped connecting portion 35 of the shaft member 30. The inside of the ring-shaped connecting portion 35 is closed by a top plate 33, and its periphery is reinforced by a short cylindrical outer frame portion 26. A lower tube portion 27 is provided at the lower end of the outer tube portion 21. The lower tube portion 27 is integrally formed with an inner tube portion 27A having a female thread 27a formed on the inner peripheral surface on the inner diameter side and an outer peripheral wall 27B on the outer diameter side, forming a roughly U-shaped cross section. In this embodiment, the outer tube portion 21 and the lower tube portion 27 are integrally molded by two-color molding or insert molding. The outer cylinder portion 21 and the lower cylinder portion 27 may also be formed as separate members and then assembled together.

[0036] A plurality of (eight in this modified example) axially extending vertical grooves 21b are formed on the inner peripheral surface of the lower end side of the outer tube portion 21 at equal intervals in the circumferential direction (at 45-degree intervals in this modified example), and a plurality of (eight in this modified example) ridges 27b that can fit into each vertical groove 21b are formed on the opposing outer peripheral wall 27B of the lower tube portion 27 at equal intervals in the circumferential direction (at 45-degree intervals in this modified example), and the lower tube portion 27 is fixed to the inside of the outer tube portion 21 by aligning and fitting each ridge 27b into each vertical groove 21b of the outer tube portion 21.

[0037] Similarly, for the outer tube portion 21 made of a soft material, it is preferable to decorate the outer wall of the outer tube portion 21 by printing or transferring, etc., so that the position that will become the pressed-in portion 21A can be easily recognized from the outside. In this case, the outer tube portion 21 made of a soft material may be molded in two colors to make it easily recognizable.

[0038] the above Variations The method of using the application container shown in FIG. Normal use is the same as in the first and second embodiments, so a description thereof will be omitted, and the case where the remaining amount of the content liquid in the container body 10 becomes small will be described. The user performs a pressing operation to press the pressed portion 21A of the outer tube portion 21 of the cap 20 radially inward. As a result, the outer tube portion 21, which is made of a soft material, elastically deforms inward, and the extension portion 32 provided inside the elastically deformed portion, more specifically the straight plate portion 32b constituting the shaft member 30, is pressed radially inward, causing the shaft member 30 to attempt to extend and displace in the axial direction intersecting the radial direction (the pressing direction). Thus, as in the first and second embodiments, the applicator portion 50 provided at the lower end of the shaft member 30 can be brought close to or into contact with the inner surface of the bottom portion 14 of the container body 10, allowing the content liquid to be used up to the last drop.

[0039] In the above-described modified example, by forming the outer cylindrical portion 21 from a soft material, the pressed portion 21A can be pressed at any position in the circumferential direction, thereby improving operability.

[0040] The configuration and effects of the present invention have been described above in accordance with the examples, but the present invention is not limited to the above examples. For example, regarding the configuration of the extension portion 32, the first embodiment described above shows a configuration having a pair of curved plate portions 32a, and the second embodiment and its modified example described a configuration having eight curved plate portions 32a, but the number of curved plate portions 32a is not limited to the above embodiments.
