By the way, an eyelash curler is known as a device for curling eyelashes. Eyelash curlers can only curl the eyelashes upwards temporarily, and over time the eyelashes will begin to recede. Therefore, if you want to curl your eyelashes again when touching up your makeup, you need to carry an eyelash curler with you. However, since eyelash curlers are large, carrying them around will add bulk to your luggage. Even if the portability of the eyelash curler were improved, both the applicator container and the eyelash curler would have to be carried, and in that case, the luggage would still be bulky. As the number of cosmetics and cosmetic tools increases, it becomes difficult to search for desired cosmetics and cosmetic tools from a makeup bag or the like.

Therefore, it is an object of the present invention to provide a cap with an applicator and an applicator container that are equipped with an applicator that can also function as an eyelash curler.

The present invention includes a cap body that is attached to the mouth of a container body in which contents are accommodated, and a cylindrical outer shaft body that is provided on the cap body and inserted into the container body through the mouth. , an application part made of an elastic body, one end of which is attached to the tip of the outer shaft, and a slit of a predetermined length formed from the one end toward the side where the other end is located; An inner shaft body is provided inside, the tip of which is inserted into the one end of the slit so as to be movable back and forth, and when the tip of the inner shaft body enters the slit, the slit opens and the application portion is inserted into the application section. An opening is formed, and when the inner shaft body is retracted from the slit, the opening is closed. The inner shaft body is formed by cutting the application part along the axial direction of the inner shaft body except for the other end toward the side where the inner shaft body The cap has a thin plate-shaped insertion part having a wide plate surface in the intersecting direction, the cut surface of the slit intersects with the plate surface, and the cap with an applicator allows the insertion part to be inserted into the slit. .

In the cap with an applicator according to the present invention, the cap body includes a cylindrical outer peripheral wall, an upper lid that closes the top surface of the outer peripheral wall, and a middle portion provided below the upper lid and inside the outer peripheral wall. a lid, and a slide part that is housed inside the outer peripheral wall so as to be movable in the axial direction of the inner shaft body between the upper lid and the middle lid, and the inner shaft body is attached to the slide part. It is also preferable that the outer shaft body is provided so as to be connected to the insertion hole and extend toward the container body.

Further, the present invention includes a container main body in which an eyelash cosmetic is stored, and the cap with the applicator, wherein the eyelashes can be inserted into and removed from the opening formed in the application section, and when the opening is closed, the eyelashes can be inserted into and removed from the opening. The application container is configured to be able to hold eyelashes inserted into the opening in a state where they are sandwiched between the slits.

According to the cap with an applicator of the present invention, the applicator made of an elastic body is attached to the tip of the outer shaft provided on the cap body. A slit of a predetermined length is formed in the applicator part from one end thereof toward the side where the other end is located. The inner shaft body is inserted into the outer shaft body, and the tip of the inner shaft body can be inserted into one end of the slit so that it can move forward and backward. When the tip of the inner shaft body enters the slit, the slit opens and an opening is created in the application section. When the inner shaft body is retracted from the slit, the slit is closed and the opening is closed. For example, when applying eyelash base, mascara, etc. stored in the container body to the eyelashes using the application section, or after applying these eyelash cosmetics to the eyelashes, insert the tip of the inner shaft body into the slit side. By forming an opening in the applicator, inserting an eyelash into the opening, and closing the opening, the eyelash inserted into the opening can be held in a state where it is sandwiched between the slits. If the applicator is rotated in this state, for example, the eyelashes will wrap around the applicator and the eyelashes can be curled. In other words, the applicator-equipped cap is equipped with an applicator that can also function as an eyelash curler, and it is possible to curl the eyelashes without carrying an eyelash curler, thereby reducing the number of items to carry.

The applicator container 100 shown in FIG. 1(a) has a cap 1 with an applicator attached to a container body 50 in which the contents are stored. It can be applied to the area to be coated. In the application container 100, the container body 50 can contain various contents such as various cosmetics, detergents, medicines, and adhesives. Further, the contents may be in various states such as liquid, gel, or cream, and may contain fibers and the like. As described above, the type and condition of the contents are not particularly limited, but in this embodiment, eyelash cosmetics such as mascara or mascara base are stored in the container body 50, and the area to be applied is The case of eyelashes will be explained as an example.

Note that "upper" and "lower" in this specification indicate a relative positional relationship, and when the coating container 100 is placed in an upright position as shown in FIG. 1(a), the shaft portion 20 The side on which the container body 50 is located in the axial direction along the central axis O of the inner shaft body 22 is referred to as "lower", and the side on which the cap body 10 is located is referred to as "upper". Further, the radial direction is a direction perpendicular to the central axis O. Further, the central axes of the container body 50, the cap body 10, the outer shaft body 21, and the applicator 30 are assumed to coincide with the central axis O of the inner shaft body 22. Further, the length in the axial direction is referred to as "height", and the length in the radial direction is referred to as "width".

First, the configuration of the container body 50 side will be explained. The container body 50 includes a bottomed cylindrical body 52 in which the contents are accommodated, and a shoulder 53 that connects the body 52 and the mouth 51. The mouth portion 51 is formed to have a smaller diameter than the body portion 52, and a threaded portion 54 is provided on the outer peripheral surface of the mouth portion 51. Further, a squeezing member 55 is provided inside the mouth portion 51. The squeezing member 55 has a cylindrical wall 56 provided along the inner circumferential surface of the mouth portion 51 of the container body 50 . The lower end portion of the cylindrical wall 56 is tapered radially inward as it goes downward in the axial direction. Furthermore, a flange 57 is provided at the upper end of the cylindrical wall 56 to cover the upper end of the mouth portion 51 .

Furthermore, an inner shaft body 22 is attached to the lower surface of the bottom surface portion 14a. Ribs 14c are provided at intervals in the circumferential direction at the joint between the bottom surface portion 14a and the inner shaft body 22.

A regulating wall 11a that protrudes inward in the circumferential direction from the inner peripheral surface of the outer peripheral wall 11 is provided between the upper lid 12 and the inner lid 13. The regulating wall 11a is formed in the shape of a thin plate that is vertically elongated in the axial direction, and its lower end abuts the upper surface of the inner lid 13, and its upper end is spaced apart from the lower surface of the upper lid 12 by a predetermined distance. When the slide portion 14 is moved downward along the axial direction, the bottom surface portion 14a of the slide portion 14 comes into contact with the upper end of the regulating wall 11a. When the slide portion 14 comes into contact with the restriction wall 11a, the slide portion 14 can no longer move downward in the axial direction.

Further, a recess 11c is formed in the outer peripheral wall 11 on one side of the central axis O (in the example shown in FIG. 1A, on the right side when facing the drawing), the recess 11c is parallel to the axial direction and recessed inward in the radial direction. (See FIGS. 2(a) and 2(b)). Note that FIG. 2(a) is a cross-sectional view taken along the line AA in FIG. 1(a). An operating section 14d that can be operated by a user is movably accommodated in the recess 11c provided in the outer peripheral wall 11. Further, as shown in FIGS. 2(a) and 2(b), a vertical groove hole 11d parallel to the axial direction is formed approximately in the center of this recess 11c. A connecting portion 14e connecting the bottom surface portion 14a of the slide portion 14 and the operating portion 14d is inserted into the vertical groove hole 11d.

Returning to FIG. 1, the inner lid 13 will be explained. The inner lid 13 has an insertion hole 13a in its center that penetrates in the thickness direction. An annular wall 13b is erected on the upper surface of the inner lid 13 so as to surround the insertion hole 13a. An inner shaft body 22 is inserted into the annular wall 13b and the insertion hole 13a. Further, a compression spring 15 is housed between the bottom surface portion 14a of the slide portion 14 and the inner lid 13. The compression spring 15 has its upper and lower ends fitted into a rib 14c provided on the lower surface of the bottom surface 14a of the slide portion 14 and an annular wall 13b provided on the upper surface of the inner lid 13. Further, an inner shaft body 22 is inserted inside the compression spring 15 .

Furthermore, a threaded portion 11b is formed on the inner circumferential surface of the outer circumferential wall 11 below the inner lid 13. The applicator-equipped cap 1 is attached to the opening 51 of the container body 50 by screwing the threaded portion 11b with the threaded portion 54 provided at the opening 51 of the container body 50.

Next, the shaft portion 20 will be explained. The outer shaft body 21 is provided on the lower surface of the inner lid 13 so as to be continuous with the insertion hole 13a and extend downward (toward the container body 50 side). The outer shaft body 21 is formed into a cylindrical shape that is elongated in the axial direction. At the tip of the outer shaft body 21, an annular recess 21a is formed on the inner peripheral surface thereof, and the applicator 30 is attached to the tip of the outer shaft body 21.

The inner shaft body 22 is attached to the lower surface of the bottom surface portion 14a of the slide portion 14 as described above, and is inserted into the outer shaft body 21 through the annular wall 13b of the inner lid 13 and the insertion hole 13a. The outer diameter of the inner shaft body 22 is smaller than the inner diameter of the outer shaft body 21, and is movable up and down in the axial direction within the outer shaft body 21. FIG. 1(b) is a front view and a bottom view showing the appearance of the tip portion of the inner shaft body 22. As shown in FIG. 1(b), the distal end portion of the inner shaft body 22 is an insertion portion 22a formed in a thin plate shape. As shown in the bottom view of FIG. 1(b), the plate surface (the widest surface) of the insertion portion 22a is orthogonal to the axial direction. Further, in the state shown in FIG. 1(a), the distal end of the insertion portion 22a is located above the distal end of the outer shaft body 21 in the axial direction.

Next, the applicator 30 will be explained. The applicator 30 is made of an elastic body integrally formed into a brush shape using an elastic material. Examples of the elastic material include rubber, thermoplastic resin elastomer, thermosetting resin elastomer, and the like.

As shown in FIG. 1(a), the applicator 30 has a notch formed by cutting a predetermined length from one end (upper end) to the side where the other end (lower end) is located. A slit 31 is provided. The slit 31 is provided along the central axis O. The applicator 30 can be separated into one side part 30a and the other side part 30b via the slit 31, except for the part where the slit 31 is not formed at the other end of the applicator part 30. However, in the state shown in FIG. 1(a), that is, in the state in which the insertion portion 22a of the inner shaft body 22 has not entered the slit 31, the one side portion 30a and the other side portion 30b are cut surfaces forming the slit 31. are in contact with each other. In the state shown in FIG. 1(a), the applicator 30 has the same function as when the slit 31 is not provided. Furthermore, although FIG. 1(c) is a cross-sectional view taken along the line BB in FIG. 1(a) of the applicator 30, as shown in FIG. The direction of the plate surface of the insertion portion 22a of the shaft body 22 is perpendicular to the direction.

Further, in this embodiment, one end of the applicator 30 is provided with an annular convex portion 32 projecting outward in the radial direction and an insertion hole 33 having a circular cross section and having approximately the same diameter as the outer diameter of the inner shaft body 22. It is being The annular convex portion 32 is fitted into an annular recess 21 a provided inside the tip of the outer shaft body 21 . The bottom of the insertion hole 33 and the tip of the slit 31 are connected. The insertion hole 33 has approximately the same width as the insertion portion 22a.

Next, an example of use of the applicator-equipped cap 1 will be described with reference to FIGS. 3 and 4. Note that some symbols are omitted in FIGS. 3(b) and 4.

FIG. 3(a) shows the application container 100 with the applicator cap 1 removed from the container body 50. This state is defined as the first form of the applicator-equipped cap 1. At this time, the insertion portion 22a of the inner shaft body 22 is housed inside the outer shaft body 21, and the slit 31 of the applicator 30 is closed. For example, when the user moves the operating part 14d downward in the axial direction with a thumb or the like, the sliding part 14 moves downward in the axial direction while the connecting part 14e is guided by the vertical groove 11d, and accordingly, the inner shaft body 22 also moves axially downward.

Next, when the slide part 14 is moved until the bottom part 14a of the slide part 14 comes into contact with the upper end of the regulating wall 11a, the cap with applicator 1 will be in the second form shown in FIG. 3(b). At this time, the insertion portion 22a of the inner shaft body 22 moves downward through the insertion hole 33 provided in the applicator 30 and enters the tip of the slit 31. The insertion part 22a is formed into a thin plate shape, and the plate surface and the cut surface of the slit 31 are perpendicular to each other, so that the slit 31 can be efficiently pushed open by entering the insertion part 22a into the slit 31. . Then, when the slit 31 is pushed wide, an opening 31a is formed in the center of the application section 30.

When the opening 31a is formed in the applicator 30, the user's eyelashes can be inserted into the opening 31a, as shown in FIG. 4(a). Then, when the force applied to the operating portion 14d is loosened with the thumb or the like, the sliding portion 14 is moved upward in the axial direction by the elastic force of the compression spring 15. Then, as shown in FIG. 4(b), the opening 31a closes with the eyelashes inserted into the opening 31a, and the eyelashes can be held in the slit 31 with the eyelashes inserted. If the cap 1 with applicator is rotated in this state so as to wrap the eyelashes around the applicator 30, the eyelashes can be curled, and the cap 1 with applicator can be used as an eyelash curler.

Note that when the applicator-equipped cap 1 is in the first form shown in FIG. An appropriate amount of the eyelash cosmetic contained in the container can be deposited and applied to the eyelashes.

As explained above, the applicator-equipped cap 1 of the present embodiment includes the applicator part 30 that can also function as an eyelash curler, and allows you to curl your eyelashes without carrying an eyelash curler. points can be reduced.

Furthermore, in this embodiment, by forming the tip portion of the inner shaft body 22 into a thin plate-like insertion portion 22a, it is possible to reduce the resistance when inserting the inner shaft body 22 into the slit 31, and it is possible to easily insert the inner shaft body 22 into the slit 31 with a light force. The inner shaft body 22 can be moved axially downward. Further, since the insertion hole 33 is provided above the slit 31 of the application section 30 in the axial direction, it is easier to move the inner shaft body 22 toward the application section 30 side. Further, since the plate surface of the insertion portion 22a is oriented perpendicular to the cut surface of the slit 31, the slit 31 can be pushed widely.

Although one embodiment of the present invention has been described above, the present invention is not limited to such a specific embodiment, and unless specifically limited by the above explanation, the present invention described in the claims Various modifications and changes are possible within the scope of the spirit. Furthermore, the effects of the embodiments described above are merely illustrative of the effects resulting from the present invention, and do not mean that the effects of the present invention are limited to the above effects.

For example, the mechanism for moving the inner shaft body 22 up and down in the axial direction is not limited to the example given in this embodiment, and of course can be modified as appropriate. For example, a rotary cam mechanism including an inner cylinder and an outer cylinder is adopted, and when the operation part 14d provided on the outer cylinder is slid up and down in the axial direction, the inner cylinder rotates, and the inner cylinder or The inner shaft body 22 connected to the operating portion 14d may be configured to move up and down in the axial direction. In either case, considering the operability when curling the eyelashes, it is recommended that the inner shaft body 22 be moved up and down in the axial direction by moving the operating part 14d up and down in the axial direction. preferable.

Furthermore, in this embodiment, a compression spring 15 is housed between the slide portion 14 and the inner lid 13, and when the slide portion 14 moves downward in the axial direction, the compression spring 15 is compressed and On the other hand, although a configuration has been adopted in which the elastic force is used to bias the slider upward, the compression spring 15 is not limited to this, and for example, a leaf spring or the like may be interposed between the slide portion 14 and the inner lid 13.

Furthermore, the compression spring 15 may be omitted and the operating section 14d may be moved upward in the axial direction by applying force to the operating section 14d with a thumb or the like. In addition, when adopting such a configuration, the operation part 14d is moved axially downward, the insertion part 22a is entered into the slit 31 and is pushed out, and the opening 31a is formed in the center of the application part 30. A force that attempts to return to the original state is applied to the one side portion 30a and the other side portion 30b due to the elastic force of the applicator 30 itself. That is, the insertion part 22a that has entered the slit 31 can maintain the state in which the opening 31a is formed in the center of the application part 30 by being held between the one side part 30a and the other side part 30b, so that the eyelashes can be removed. The work of inserting into the opening 31a becomes easier. After that, when the operating part 14d is moved upward in the axial direction, the opening 31a closes and the eyelashes can be held in the slit 31. All you have to do is rotate the cap 1.
