Description

  The present invention relates to a liquid cosmetic applicator.

  2. Description of the Related Art Conventionally, as a mascara applicator, an applicator in which an application part such as a brush extending in the axial direction of a shaft body is provided at one end of a shaft body, and a gripping part is formed at the other end of the shaft body, and a cylinder for storing liquid cosmetics The container body is used as a cap of the container body when the applicator shaft is inserted into the container body from the application section side.

  However, when the mascara is applied to the eyelid with such an applicator, the shaft body is used horizontally, so the mascara is applied to which eyelid to which the left and right eyes are applied or to any part of the eyelid. Depending on whether it is applied, it is necessary to change the applicator from one hand on the left to the other hand, or twist the arm, which makes the application work inconvenient.

  In contrast, one end of the brush is held by a fixed shaft fixed to the cap, the other end is held by a reciprocating shaft that can be advanced and retracted, the advancing and retracting shaft is attached to a slide button provided on the cap, and the slide button is provided on the cap It has been proposed to advance and retract the advance / retreat axis by sliding along the groove, thereby changing the angle of the brush axis relative to the axis of the cap (Patent Document 1).

JP2013-81661A

  However, if the cap is provided with a slide button as in the applicator described in Patent Document 1, the groove for sliding the slide button communicates the inside and outside of the cap even when the container body is closed with the cap. The inside of the cap and the inside of the container main body communicate with each other, and it becomes difficult to ensure the airtightness in the container main body.

  Since a highly volatile solvent is used for the mascara, if the airtightness in the container main body is not sufficiently ensured, the mascara dries in the container main body and becomes difficult to use.

  Further, if a slide button is provided on the cap or an advancing / retracting shaft is attached to the slide button, the number of parts increases, the manufacturing process becomes complicated, and the manufacturing cost of the mascara applicator increases.

  Accordingly, the problem to be solved by the present invention is that the liquid cosmetic applicator provided with an application body at one end of the shaft serves as a grip portion when the liquid cosmetic is applied in order to facilitate the liquid cosmetic application operation. To provide a device capable of suppressing the manufacturing cost because the axial direction of the coating part is inclined with respect to the axial direction of the cap and the cap is closed and has high airtightness, and has a small number of components. is there.

  Regarding the above-mentioned problems, a ring-shaped branching portion is formed in the shaft of the liquid cosmetic applicator, and when the branching portion passes through the ironing portion near the mouth portion of the container body, it becomes a straight bar shape and is taken out from the container body. After forming a plurality of hinge parts in the branch part so as to restore itself to the ring shape after itself, it becomes possible to easily apply the liquid cosmetic using the branch part restored to the ring shape, It is also possible to seal the container body while the shaft body is housed in the container body. Furthermore, if such a shaft body is formed by integral molding using a flexible resin, the liquid cosmetic applicator is less expensive with fewer parts. The liquid cosmetic applicator of the present invention having such a branching portion was completed.

The present invention provides a container body for storing a liquid cosmetic,
A cap for detachably sealing the container body;
A liquid cosmetic applicator provided with a shaft body that is attached to a cap and accommodated in the container body with the container body closed by the cap, and a squeezing portion that wipes the shaft body in the container body,
The shaft body has a branch portion integrally molded with a flexible resin, and the branch portion is molded into a ring shape that can be deformed into a straight rod shape by connecting a plurality of shaft portions with hinge portions,
Provided is a liquid cosmetic applicator in which a part of a branch part forms an application part for applying liquid cosmetic.

  Moreover, this invention provides the cosmetics by which liquid cosmetics are accommodated in the container main body of the above-mentioned liquid cosmetic applicator.

  According to the liquid cosmetic applicator of the present invention, since the branch portion of the shaft body can be deformed into a straight rod shape, when the shaft body is taken out from the container body containing the liquid cosmetic material, the shaft body should be sufficiently squeezed. Therefore, the coating portion formed on the shaft body can be sufficiently squeezed.

  Further, when the shaft body is taken out from the container main body, the branch portion of the shaft body naturally returns to the original ring shape. Since the application portion is formed at the branch portion of the shaft body, the axial direction of the application portion can be inclined with respect to the axial direction of the cap in a state where the shaft body is taken out from the container body. Thereby, for example, when the liquid cosmetic is a mascara, the mascara is applied to the eyelids on either side of the eye compared to the conventional mascara applicator in which the application portion, the shaft body, and the cap are arranged linearly. It becomes easy to apply.

  Furthermore, since the branch part of the shaft body, which has been in the shape of a straight bar when passing through the ironing part, returns to the ring shape simply by removing it from the container body, a slide button or the like for making the shaft body into a ring shape can be provided on the cap. It is unnecessary. Therefore, the inside of the container body is sealed with the cap closed, and the liquid cosmetic can be prevented from drying.

  Since the branch part of the shaft body is manufactured by integral molding, it can be manufactured at low cost.

  The liquid cosmetic applicator 1A is detachably attached to the container body 10 by screwing into the container body 10 containing the liquid cosmetic A such as mascara and the mouth of the container body 10, and the inside of the container body is sealed. A cap 20, a shaft body 30 accommodated in the container body 10 in a state where the container body 10 is closed by the cap 20, and a squeezing portion 11 for wiping the shaft body 30 in the container body 10.

2 shaft body
2-1 Branching portion The shaft body 30 has a branching portion 32 in which a plurality of shaft portions are connected by a hinge portion. More specifically, a round bar-shaped shaft body base portion 35 extends from the bottomed cylindrical cap 20 in the direction of the axis La of the cap 20, and the first shaft portion 33 a and the fifth shaft portion 33 e extend from the shaft body base portion 35. The second shaft portion 33b is connected to the first shaft portion 33a via the hinge portion 34a, the third shaft portion 33c is connected to the second shaft portion 33b via the hinge portion 34b, and the third shaft portion 33b is connected to the first shaft portion 33a. A fourth shaft portion 33d is connected to the shaft portion 33c via a hinge portion 34c, and a fifth shaft portion 33e is connected to the fourth shaft portion 33d via a hinge portion 34d. These five shaft portions and four hinges The branch part 32 is formed by the part.

  Here, the first shaft portion 33a and the fifth shaft portion 33e extend in parallel with the axis line La of the cap 20, and the first shaft portion 33a is longer than the fifth shaft portion 33e. It has become. The fourth shaft portion 33d extends obliquely with respect to the cap axis line La, and the length of the fourth shaft portion 33d is longer than that of the first shaft portion 33a.

  The hinge portions 34a, 34b, 34c, and 34d between the shaft portions are formed in a V-notch shape and have a thin portion. In each hinge part 34 a, 34 b, 34 c, 34 d, the V-shaped groove of the V notch faces the outside of the ring shape of the branch part 32.

  The branch portion 32 is integrally molded using a flexible resin. As shown in FIG. 1, the branch portion 32 is branched in an original state in which the shaft body 30 is completely removed from the container body 10 and no external force is applied. The part 32 has a ring shape. In the present embodiment, the ring shape is a polygon having one side of the first shaft portion 33a along the axis La of the cap 20, and is formed on one side of the axis La in plan view.

  The shaft portions 33a, 33b, 33c, 33d, and 33e and the shaft body base portion 35 of the branch portion 32 are difficult to bend by hand, but the hinge portions 34a, 34b, 34c, and 34d are easily bent. The total length of the first shaft portion 33a and the second shaft portion 33b is equal to the total length of the third shaft portion 33c and the fourth shaft portion 33d. Therefore, as shown in FIG. 3, in the process of pulling out the shaft body 30 from the container body 10, the branch part 32 is deformed into a straight bar shape by being pressed by the mouth part 14 or the ironing part 11 of the container body 10, After pulling out, that is, after the pressing is released, the original ring shape is naturally restored.

  As shown in FIG. 3, the shaft body base 35 has a cylindrical shape, but the first shaft portion 33a and the fifth shaft portion 33e each have a semicircular cross section, and the other shaft portions 33b. 33c and 33d have a semicircular cross section. Therefore, the outer shape in a state where the branching portion 32 is deformed into a straight bar shape is a columnar shape, and the insertion and removal to the ironing portion 11 is smooth.

  The flexible resin forming the shaft body 30 preferably has a flexural modulus of 750 to 3000 MPa (test method: ASTM D790) from the viewpoint of enabling the above-described branching portion 32 to be deformed and restored. Specifically, polypropylene, nylon, polyacetal, polybutylene terephthalate, or the like can be used.

2-2 Application part The 2nd axial part 33b and the 3rd axial part 33c are provided with the comb part shape | molded at the time of integral molding as the application part 31. As shown in FIG. In the present invention, the application part 31 is not limited to the comb part, and the raised part may be formed by insert molding, double injection molding or the like. Further, a flocking process may be performed after the integral molding.

2-3 Guide The fourth shaft portion 33d that extends obliquely with respect to the axis line La of the cap 20 from the vicinity of the end portion on the cap 20 side of the branching portion 32 has a fourth shaft portion 33c side end portion thereof. A rod-shaped guide 36 protruding in the axial direction of the shaft portion 33d is bonded. As will be described later, when the shaft body 30 outside the container main body 10 is accommodated in the container main body 10, the guide 36 can easily fold the branch portion 32 opened in a ring shape into a straight bar shape. Become.

  Further, the guide 36 may be provided with irregularities, formed into a plurality of branched shapes, a raised portion, or a flocking process. Thereby, the application | coating function of liquid cosmetics and the finishing function of the detail after apply | coating liquid cosmetics by the application part 31 can be given to the guide 36. FIG.

2-4 Manufacturing Method of Shaft Body As a manufacturing method of the shaft body 30, a straight rod-shaped molded body having a V-shaped groove forming the hinge portions 34a, 34b, 34c, and 34d and having a semicircular cross section is formed. Then, the shaft body 30 may be formed by fixing both ends thereof together, and the guide 36 may be bonded to the shaft body 30, or the shaft body 30 including the guide 36 may be integrally molded. .

  As shown in FIG. 2, the shaft body 30 is attached to the cap 20 by fixing the shaft body 30 to the cap 20 that can seal the container body 10.

3 Container Main Body The container main body 10 has a circular outer shape of the mouth portion 14 and the bottom surface 15, and has a tapered shape in which the outer diameter of the mouth portion 14 is smaller than the outer shape of the bottom surface 15. It is smaller than the inner diameter L2 of the bottom surface 15. The inner diameter L1 of the mouth portion 14 is large enough to pass the branch portion 32 deformed into a straight rod shape, but the radius (1/2 of the inner diameter L2) of the bottom surface 15 inside the container body 10 is outside the container body 10. A certain shaft body 30 is smaller than the maximum width in the direction perpendicular to the axis La of the cap 20 (hereinafter, referred to as an opening width L3 of the branch portion 32). For this reason, the opening width L3 ′ (FIG. 2C) of the branch portion 32 in a state where the shaft body 30 is accommodated in the container body 10 is the same as that when the shaft body 30 is extended out of the container body 10. The opening width L3 (FIG. 1) of the branch part 32 becomes narrower. Thus, by accommodating the shaft body 30 by narrowing the opening width L3 of the branch portion 32 in the container body 10, the liquid cosmetic applicator 1A can be made compact.

  The opening width L3 of the branching portion 32 in the container main body 10 is enhanced from the point of increasing the restoring force to the ring shape when the branching portion 32 goes out of the container main body 10 and securing a certain opening width of the branching portion 32. It is preferable to determine the inner dimension of the container body 10 so that 'is 80% or more and 100% or less of the opening width L3 of the branch portion 32 outside the container body 10. As will be described later, when the convex portion 37 is provided in the vicinity of the hinge portion 34d near the cap 20 inside the annular shape of the branch portion 32 (FIG. 7), the opening width of the branch portion 32 in the container body 10 L3 ′ is preferably 50% or more and 100% or less of the opening width L3 of the branch portion 32 outside the container body 10.

  The outer wall of the mouth portion 14 of the container body 10 is provided with a screw 13 that is screwed into the inner wall of the cap 20 so that the inside of the container body 10 can be sealed with the cap 20.

  Further, the ironing member 12 is attached to the mouth portion 14 of the container body 10. The ironing member 12 is a bottomed cylindrical elastic member that is formed into a mortar shape, has a hole in the bottom, and the bottom becomes the ironing portion 11. It is preferable that the ironing part 11 is formed with cuts radially around the hole. When the ironing member 12 is formed in a bowl shape and has a hole in the bottom, the shaft body 30 that is opened in an annular shape when the shaft body 30 taken out from the container body 10 is accommodated in the container body 10. Is easily deformed into a straight bar shape.

  In a state where the shaft body 30 is accommodated in the container main body 10, the ironing portion 11 is preferably on the cap 20 side with respect to the branch portion 32 of the shaft body. Thereby, while the shaft body 30 is accommodated in the container main body 10, it is possible to prevent the squeezing part 11 from being constantly spread by the force of the branching part 32 trying to restore the ring shape. Since the squeezing part 11 prevents the force at which the branching part 32 restores to the ring shape from being constantly obstructed, the restoration from the straight rod-like branching part 32 to the ring-shaped branching part 32 is prevented. It is possible to prevent a decrease in force.

4 How to Use Liquid Cosmetic Applicator This liquid cosmetic applicator 1A can be used, for example, as follows.
2, the container body 10 is filled with liquid cosmetics such as mascara, eyebrow, eyeliner (such as eyebrow cosmetics), lip gloss (such as lip cosmetics), and the container body 10 is sealed with a cap 20. The liquid cosmetic applicator 1 </ b> A is distributed as cosmetics in a sealed state.

  The user holds the cap 20 of the liquid cosmetic applicator 1 </ b> A, removes the cap 20 from the container body 10, and pulls the shaft body 30 from the container body 10. At this time, the branch portion 32 that is ring-shaped in the container main body 10 is pressed by the ironing portion 11 when passing through the mouth portion 14 of the container main body 10, and becomes a straight bar shape as shown in FIG. It's going to be ridiculous. Thereby, the excess liquid cosmetic A can be removed from the shaft body 30, particularly from the application part 31.

  When the shaft body 30 is pulled out from the container body 10 and the pressing from the ironing portion 11 is released, the branching portion 32 opens into an original ring shape as shown in FIG. At this time, the axis Lb of the application part 31 is inclined with respect to the axis La of the cap 20. Therefore, as shown in FIG. 5, it becomes easy to apply the liquid cosmetic to both the left and right eyelids. Therefore, depending on whether the mascara is applied to which eyelid on the left or right eye, like in a conventional liquid cosmetic applicator in which the axis of the cap and the axis of the application part are linearly arranged, or which part of the eyelid It is possible to alleviate the difficulty of the application work that occurs depending on whether the mascara is applied.

  Next, when the application unit 31 is accommodated in the container body 10, as shown in FIG. 4, the application unit 31 faces the mouth part 14 of the container body 10 (FIG. The guide 36 of the shaft body 30 is applied to the inner wall of the portion 14 (FIG. 2B), and the first shaft portion 33a is pressed against the fourth shaft portion 33d (FIG. 1C). Accordingly, the branch portion 32 can be deformed from a ring shape to a rod shape without directly touching the branch portion 32 by hand ((c) in the figure). Next, the cap 20 is pushed in the direction of the container body 10 ((d) in the figure). At this time, if the inside of the ironing member 12 has a mortar shape that narrows toward the ironing portion 11, the shaft body 30 can be easily pushed into the container body 10. After housing the shaft body 30 in the container main body 10, the cap 20 is screwed into the mouth portion 14 of the container main body 10 ((e) in the figure). The inside of the container body 10 is sealed by this screwing, and the solvent is prevented from evaporating from the liquid cosmetic A.

5 Modified Mode The liquid cosmetic applicator of the present invention can take various modes.
5-1 Shaft body The portion where the cap 20 and the shaft body 30 are fixed in the liquid cosmetic application part 1A described above. The shaft portion 33a of the shaft body 30 and the axis La of the cap 20 may be made non-parallel. Thereby, the diameter of the cap 20 and the diameter of the container main body 10 can be made into the substantially same magnitude | size.

5-2 Branching portion As shown in FIG. 7, the branching portion 32 is deformed into a straight rod shape on the shaft portion 33a or 33d in the vicinity of the hinge portion 34d near the cap 20 inside the annular shape of the branching portion 32. It is preferable to provide the convex part 37 which presses the axial part when it is. Thereby, the restoring force to the ring shape can be increased when the pressing is released with respect to the branch portion 32 deformed into a straight bar shape by the pressing.

  As in the liquid cosmetic applicator 1B shown in FIG. 8, the fourth shaft portion 33d extending obliquely with respect to the axis La of the cap 20 from the vicinity of the end portion of the branch portion 32 on the cap 20 side, The third shaft is formed at the end of the third shaft portion 33c which is formed in a short length with respect to the first shaft portion 33a extending from 35 and is connected to the fourth shaft portion 33d via the hinge portion 34c. You may provide the guide 36 which protruded in the axial direction of the part 33c. The guide 36 is pressed against the inner wall of the mouth portion of the container body 10, and the first shaft portion 33a is pressed against the third shaft portion 33c (FIG. 5B). As a result, the branch portion 32 closes from the ring shape to the rod shape, so that the cap 20 is pushed in the direction of the container body 10 ((c) in the same figure), and the shaft body 30 is accommodated in the container body 10. It becomes possible to do.

  As described above, the length of each shaft portion forming the branch portion 32 can be appropriately changed as long as the branch portion 32 can be deformed into a straight rod shape.

  The liquid cosmetic applicator 1C shown in FIG. 9A is different from the liquid cosmetic applicator 1A shown in FIG. 1 in that the V-shaped grooves of the hinge portions 34a, 34c and 34d are connected to the ring of the branch portion 32. The hinge part 34b is directed to the outside while facing the inside of the shape. In this liquid cosmetic applicator 1C, the branch portion 32 is deformed into a straight bar shape as shown in FIG.

  Thus, when the hinge portion is formed from a V-shaped groove, the direction of the groove and the angle of opening can be appropriately set so that the branch portion 32 can take a desired ring shape and straight rod shape.

  According to this liquid cosmetic applicator 1C, the ring-shaped outer periphery of the branch portion 32 when the liquid cosmetic is applied becomes smooth.

  The liquid cosmetic applicator 1D shown in FIG. 10 has a V-shaped hinge 34a between the first shaft portion 33a and the second shaft portion 33b in the liquid cosmetic applicator 1A shown in FIG. Instead of forming with a groove, the first shaft portion 33a and the second shaft portion 33b are made continuous with a gently curved shaft portion.

  As described above, when the shaft portion is gently bent by the hinge portion 34a, the hinge portion 34a may be formed thin.

5-3 Container Body The liquid cosmetic applicator 1E shown in FIG. 11 has a substantially oval bottom at the bottom of the container main body 10 with respect to the liquid cosmetic applicator 1A shown in FIG. In the top view, the branch portion 32 of the shaft body 30 can maintain the original ring shape in a state where the mouth portion 14 of the container body 10 is eccentric in the longitudinal direction of the bottom portion and the shaft body 30 is accommodated in the container body 10. It is what I did. In this case, in order to make the longitudinal direction of the bottom part of the container main body 10 coincide with the direction of the opening width of the branch part 32 of the shaft body 30, the cap 20 is formed so as to be fitted to the container main body 10 in a predetermined direction. ing.

  Thus, if the branch part 32 can maintain the original ring shape in the container body 10, the straight bar-like branch part 32 when the shaft body 30 is pulled out from the container body 10 to the outside of the container body 10. A reduction in restoring force to the ring-shaped branch portion 32 can be prevented.

  The liquid cosmetic applicator 1F shown in FIG. 13 is not provided with a guide 36 at the shaft portion, and the mouth portion 14 of the container body 10 has a mortar shape with an opening diameter similar to the opening width L3 of the branch portion 32. It is open. In this liquid cosmetic applicator 1 </ b> F, when the shaft body 30 (FIG. 10A) drawn from the container body 10 is accommodated in the container body 10, first, the lower part of the branch part 32 is formed in the mortar-shaped opening 14. Press against the inner wall and push the shaft 30 downward along the inner wall. Thereby, the branch part 32 opened in the ring shape is deformed into a straight bar shape and passes through the ironing part 11 ((c) in the figure). The shaft body 30 is accommodated in the container body 10, and the cap 20 seals the mouth portion 14 of the container body 10. Also in this liquid cosmetic applicator 1F, when the shaft body 30 is taken out from the container body 10, the branch portion 32 is restored to an annular shape.

  In the liquid cosmetic applicator 1G shown in FIG. 14, in a state where the shaft body 30 is taken out from the container body 10 (FIG. 14A), the branch portion 32 has six shaft portions 33a, 33b, 33c, 33d, 33e, 33f and five hinge portions 34a, 34b, 34c, 34d, 34e are formed in a symmetrical triangle in plan view. Here, the hinge part 34c which becomes the lower end when the branch part 32 is deformed into a straight bar shape is not bent when the shaft body 30 is outside the container body 10, and third hinges on both sides of the hinge part 34c. The shaft portion 33c and the fourth shaft portion 33d are in a straight line to form the application portion 31. The hinge part 34c of the application part 31 is I so that the application part 31 does not bend in the direction of the cap 20 by the hinge part 34c even if the application part 31 is pressed in the direction of the cap 20 from the body to be applied during application of the liquid cosmetic. It has a notch in shape.

  In this liquid cosmetic applicator 1G, since the axis Lb of the application part 31 is perpendicular to the axis La of the cap 20, even when applying liquid cosmetics such as mascara on either the left or right side, the application work is easy. become.

  On the other hand, these hinge portions are formed with V-shaped grooves so that the second hinge portion 34b and the fourth hinge portion 34d can be easily opened when pressed to reduce the opening width of the branch portion 32. . Therefore, when the shaft body 30 of the liquid cosmetic applicator 1G is accommodated in the container body 10, the hinge portions 34b or the hinge portions 34d at both ends of the application portion 31 are pressed against the inner wall of the mortar-shaped opening 14 (see FIG. b)), the shaft body 30 is pushed downward along the inner wall ((c) in the figure). As a result, the opening width of the branch portion 32 is narrowed and passes through the ironing portion 11 in a straight bar shape. When the branch part 32 completely enters the container main body 10, the branch part 32 becomes a ring shape with an original opening width. In this state, the inside of the container body 10 can be sealed with the cap 20 ((d) in the figure).

  On the other hand, when the shaft body 30 is taken out from the container body 10, the cap 20 is gripped and the cap 20 is pulled up from the container body 10. At this time, the second shaft portion 33 b and the fifth shaft portion 33 e are pressed by the bottom side inner wall of the mouth portion 14 so as to approach each other, and the branch portion 32 becomes a straight bar shape and passes through the ironing portion 11.

  The various deformation modes described above can be combined as appropriate, and in any mode, when the shaft body 30 accommodated in the container body 10 is pulled out of the container body 10, the branching portion 32 has a straight rod shape. When it passes through the ironing part 11 and the branch part 32 finishes passing through the ironing part 11, it naturally becomes an original ring shape due to the restoring force of the branch part, and the axis Lb of the application part 31 becomes the axis La of the cap 20 Lean against. For this reason, it becomes possible to apply | coat liquid cosmetics easily to to-be-coated bodies, such as a wrinkle. Further, since the shaft body 30 is easily formed into a straight bar shape by pressing, the shaft body 30 can be accommodated in the container body 10 and the inside of the container body 10 can be sealed.

In relation to the above-described embodiment, the present invention further discloses the following liquid cosmetic applicator.
