DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, the configuration of a brush-type applicator according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0014] As shown in Fig. 1, a brush-type applicator 1 according to a first embodiment of the present invention has a grip part 10 and an applicator part 20. In this first embodiment, a rod part 11 is attached to the grip part 10, and the applicator part 20 is provided at the tip of the rod part 11.

[0015] The handle 10 is configured in a cap shape, and by screwing the handle 10 into the mouth 2a of the container body 2, the brush-type applicator 1 is attached to the container body 2, and together with the container body 2, they form an applicator container 3. The container body 2 can contain a liquid application product such as mascara or hair dye. When the brush-type applicator 1 is attached to the container body 2, the application product 20 is disposed inside the container body 2. The container body 2 may be configured to include a rubbing part 2b at the mouth 2a for rubbing the application product attached to the application product 20.

[0016] As shown in FIGS. 2 and 3, the applicator 20 includes a base 21, a plurality of comb teeth 22, a plurality of bridging portions 23, an impregnating body 24, a stopper portion 25, and an opening / closing portion 26.

[0017] The base 21 is made of a synthetic resin material and is formed into a long rectangular plate shape, and one end of the base 21 in the longitudinal direction is integrally connected to the tip of the rod portion 11. One surface of the base 21 facing in the thickness direction (the direction of the paper in FIG. 2) is the application surface 21a.

[0018] The plurality of comb teeth 22 are arranged in two rows on the application surface 21a of the base 21 along the longitudinal direction of the base 21 (the vertical direction in FIG. 2). The number of comb teeth 22 in one row is the same as the number of comb teeth 22 in the other row, and the arrangement of the plurality of comb teeth 22 in each row is also the same. In this first embodiment, each comb tooth 22 has a mountain-like shape that gradually becomes thinner from the bottom end to the tip, and is formed integrally with the base 21 from a synthetic resin material. Note that, for convenience, only some of the comb teeth 22 are labeled with reference numerals in FIGS. 2 and 3.

[0019] The plurality of bridging portions 23 are provided on the application surface 21a of the base 21. Each of the plurality of bridging portions 23 is formed integrally with the base 21 from a synthetic resin material.

[0020] More specifically, each of the bridging portions 23 has a pair of pillar portions 23a provided between adjacent comb teeth 22 in each row, and a bridge portion 23b connecting the pillar portions 23a in one row to the pillar portions 23a in the other row. In the first embodiment, the bridging portions 23 are arranged such that three comb teeth 22 are sandwiched between each other in each row. Furthermore, in the first embodiment, in each bridging portion 23, the width of the pillar portion 23a at the portion connected to the application surface 21a, when viewed from the side perpendicular to the longitudinal direction, is equal to the width of the comb teeth 22 at the portion connected to the application surface 21a. The width of the pillar portion 23a gradually narrows slightly from the portion connected to the application surface 21a toward the upper end, and a sharp portion similar to the upper end of the comb teeth 22 is integrally formed at the upper end of the base. As shown in FIG. 4, the bridge portion 23b is integrally connected to the upper end portion of each pillar portion 23. Therefore, each of the bridging portions 23 is in the form of a gate having an opening.

[0021] The impregnated body 24 is formed into a rod shape with a rectangular cross section from a material capable of being impregnated with a liquid coating material, such as a sponge or a foam material such as polyurethane foam. The cross section perpendicular to the longitudinal direction of the impregnated body 24 corresponds to the opening defined by the base 21 and the gate-shaped bridging portions 23. As shown in Figures 2 and 3, the impregnated body 24 is inserted into each of the multiple bridging portions 23 between the two rows of comb teeth 22 and is placed on the coating surface 21a of the base 21.

[0022] In this first embodiment, the height of the impregnated body 24 from the application surface 21a of the base 21 is slightly higher than the height of the bridge portions 23b from the application surface 21a, and the bridge portions 23b abut against the upper surface of the impregnated body 24, slightly recessing the upper surface of the impregnated body 24. As a result, the impregnated body 24 is securely held by the multiple bridging portions 23 so that it does not easily move in the longitudinal direction.

[0023] The stopper portion 25 is provided on the application surface 21a at one end side of the base 21 that faces the gripping portion 10, and faces one end 24a of the impregnated body 24. In the first embodiment, two stopper portions 25, each having the same shape as the comb teeth 22, are provided side by side at a distance on the application surface 21a between the pair of comb teeth 22 that are arranged closest to the gripping portion 10 in each row. Note that the shape, number, arrangement, etc. of the stopper portions 25 can be changed as appropriate, as long as they are provided on one end side of the base 21 that faces the gripping portion 10 and face one end 24a of the impregnated body 24.

[0024] 2 and 3, the opening / closing portion 26 is provided on the application surface 21a at the other end side of the base 21. More specifically, the opening / closing portion 26 is provided on the application surface 21a at the other end side of the base 21 from the other end 24b of the impregnated body 24, which faces the opposite side from the stopper portion 25 in the longitudinal direction. The opening / closing portion 26 is deformable between a holding state in which it engages the other end 24b of the impregnated body 24 to hold the impregnated body 24 inside the multiple bridging portions 23, and an open state in which it opens the other end 24b of the impregnated body 24.

[0025] 2, 3 and 5, in the first embodiment, the opening / closing unit 26 has a pair of opening / closing unit pillars 26a provided adjacent to each row of comb teeth 22 on the other end side of the base 21, and an inverted portion 26b connected at one end to one of the opening / closing unit pillars 26a so as to be rotatable in a direction toward and away from the base 21, and connected at the other end to the other opening / closing unit pillar 26a so as to be rotatable in a direction toward and away from the base 21, and which is bendable at the center in a direction toward and away from the base 21. In other words, the opening / closing unit 26 is gate-shaped with an opening.

[0026] More specifically, when viewed from the side perpendicular to the longitudinal direction, each of the opening / closing unit pillars 26a has a shape similar to that of the pillars 23a of the bridging portion 23 and is disposed adjacent to the pair of comb teeth 22 located closest to the gripping portion 10 in each row. Each of the inverted portions 26b has connecting portions 26c at both ends thereof that are connected to the corresponding opening / closing unit pillars 26a. Each connecting portion 26c is thinner than the other portions of the inverted portion 26b and is integrally connected to the upper end of the corresponding opening / closing unit pillar 26a. Elastic deformation of each connecting portion 26c allows each of the inverted portions 26b to rotate toward or away from the base 21 relative to the corresponding opening / closing unit pillars 26a. Furthermore, a central portion 26d between the pair of connecting portions 26c of each of the inverted portions 26b is thinner than the other portions of the inverted portion 26b, excluding the connecting portions 26c. Furthermore, the total length of the inverted portion 26b from one connecting portion 26c to the central portion 26d and the length from the other connecting portion 26c to the central portion 26d is longer than the distance between the pair of opening / closing portion pillar portions 26a.

[0027] With this configuration, the opening / closing part 26 can be transformed into a holding state in which the side approaching the base 21, i.e., the central part 26d, is closer to the base 21 than the connecting part 26c, and the inverted part 26b faces the other end 24b of the impregnation body 24, as shown in Fig. 5, and an open state in which the side away from the base 21, i.e., the central part 26d, is farther from the base 21 than the connecting part 26c, and the inverted part 26b is positioned above the top surface of the impregnation body 24 at the other end 24b of the impregnation body 24, as shown in Fig. 6. The transformation of the inverted part 26b between the holding state and the open state can be easily performed by manually manipulating the central part 26d of the inverted part 26b up and down, for example.

[0028] 2, 3 and 5, when the opening / closing section 26 is in the retained state, the impregnation body 24 is inserted into the multiple bridging sections 23, with one end 24a facing the stopper section 25 and the other end 24b facing the inverted section 26b of the opening / closing section 26, and therefore the impregnation body 24 is retained on the base 21 without falling off the multiple bridging sections 23. On the other hand, as shown in FIGS. 6 and 7, when the opening / closing section 26 is in the open state, the inverted section 26b is located above the upper surface of the impregnation body 24 at the other end 24b of the impregnation body 24, and therefore the impregnation body 24 can be inserted into or pulled out of the multiple bridging sections 23 from the opening / closing section 26 side along the longitudinal direction of the base 21.

[0029] Thus, with the brush-type applicator 1 according to the first embodiment, the impregnated body 24 can be securely held on the base 21 by bending the inverted portion 26b toward the base 21 to place the opening / closing body 26 in a holding state, while the impregnated body 24 can be attached to and detached from the applicator part 20 from the other end of the base 21 by bending the inverted portion 26b away from the base 21 to place the opening / closing body 26 in an open state.

[0030] Fig. 8 is a cross-sectional view of the applicator part of a brush-type applicator according to a second embodiment of the present invention, corresponding to Fig. 3, Fig. 9 is a cross-sectional view taken along line DD in Fig. 8, Fig. 10 is a cross-sectional view of the applicator part with the opening / closing part in an open state, corresponding to Fig. 9, Fig. 11 is a view showing how the impregnated body is attached to and detached from the applicator part of a brush-type applicator according to a second embodiment of the present invention, and Fig. 12 is a cross-sectional view taken along line EE in Fig. 8. In Figs. 8 to 12, members and parts corresponding to those described above are denoted by the same reference numerals, and repeated explanations will be omitted where appropriate.

[0031] 8 to 12, the brush-type applicator 30 according to the second embodiment of the present invention has basically the same configurations as the brush-type applicator 1 according to the first embodiment in terms of the base 21, the plurality of comb teeth 22, the plurality of bridging portions 23, the impregnated body 24, and the stopper portion 25. However, the brush-type applicator 30 according to the second embodiment differs from the brush-type applicator 1 according to the first embodiment in the configuration of the opening / closing portion 26.

[0032] 8 and 9, in the brush-type applicator 30 according to the second embodiment, the opening / closing section 26 has a pair of inclined pillars 26e for the opening / closing section provided adjacent to each row of comb teeth 22 on the other end side of the base 21 and extending obliquely so that their upper ends are spaced apart, and a bendable bending section 26f formed in an arch shape convex in the direction away from the base 21, connected at one end to one inclined pillar 26e for the opening / closing section and connected at the other end to the other inclined pillar 26e for the opening / closing section. That is, in the second embodiment as well, the opening / closing section 26 is gate-shaped with an opening.

[0033] More specifically, the pair of inclined pillars 26e for the opening / closing unit are each formed in a plate shape and extend obliquely from the base 21 so that their upper ends are spaced apart. At the upper ends, a plate-like operating section 26g, thinner than the inclined pillars 26e for the opening / closing unit, is integrally provided and extends obliquely like the corresponding inclined pillars 26e for the opening / closing unit. The bent section 26f is arch-shaped overall, and includes a pair of connecting sections 26h, each of which is bent into a dogleg shape and connected to a step at each end adjacent to the operating section 26g at the upper end of the inclined pillars 26e for the opening / closing unit. Furthermore, the central section of the bent section 26f is thicker than the connecting section 26h. In its natural state, the bent section 26f faces the other end 24b of the impregnation body 24.

[0034] With this configuration, the opening / closing unit 26 of the brush-type applicator 30 according to the second embodiment is in a natural state, with the bent portion 26f facing the other end 24b of the impregnated body 24, thereby establishing a holding state, as shown in Fig. 9. Meanwhile, in the brush-type applicator 30 according to the second embodiment, as shown in Fig. 10, the pair of opening / closing unit inclined pillar portions 26e can be elastically deformed so as to approach each other, for example by pinching the pair of operation portions 26g with fingers, thereby deforming the bent portion 26f in a direction away from the base 21, thereby placing the opening / closing unit 26 in an open state. In the open state shown in Fig. 10, the pair of opening / closing unit inclined pillar portions 26e elastically deform so as to approach each other, forming an angle close to perpendicular to the application surface 21a, and the angle formed between the pair of connecting portions 26h and the corresponding opening / closing unit inclined pillar portions 26e becomes smaller, so that the central portion of the bent portion 26f moves upward, and the opening of the opening / closing unit 26 assumes a shape closer to a rectangle. Therefore, when the bent portion 26f moves upward and the opening / closing portion 26 is in an open state, as shown in Fig. 11, the impregnation body 24 can be inserted into or pulled out from the plurality of bridging portions 23 along the longitudinal direction of the base 21 from the side of the opening / closing portion 26. When the operation of the pair of operating portions 26g is released, the pair of opening / closing portion inclined column portions 26e and connecting portion 26h return to their original shapes by their own elastic force, and the opening / closing portion 26 is in a held state.

[0035] In this way, with the brush-type applicator 1 according to the second embodiment, the bent portion 26f is placed opposite the other end 24b of the impregnated body 24 to hold the opening / closing portion 26, thereby securely holding the impregnated body 24 on the base 21, and the pair of inclined pillar portions 26e for the opening / closing portion are elastically deformed so as to move closer to each other, thereby deforming the bent portion 26f in a direction away from the base 21 and placing the opening / closing portion 26 in an open state, thereby enabling the impregnated body 24 to be attached to and detached from the applicator portion 20 from the other end side of the base 21.

[0036] In the brush-type applicator 1 according to the second embodiment, as shown in Fig. 12, through-holes 27 are provided in the portions of the base 21 where the multiple bridging portions 23 are provided, penetrating from the application surface 21a to the back surface 21b. This configuration allows the liquid contents to be impregnated into the impregnated body 24 from the back surface 21b as well as from the application surface 21a, thereby more quickly and reliably impregnating the contents into the impregnated body 24. Furthermore, this configuration allows the inner periphery of the bridging portions 23 to be formed by the portions inserted into the through-holes 27 of the mold when the applicator part 20 is injection-molded using a mold (not shown), thereby further simplifying the configuration of the mold for injection-molding the applicator part 20.

[0037] The through-hole 27 may be applied to the base 21 of the brush-type applicator 1 according to the first to third embodiments.

[0038] Fig. 13 is a front view of the applicator part of a brush-type applicator according to a third embodiment of the present invention, corresponding to Fig. 2, Fig. 14 is a cross-sectional view taken along line FF in Fig. 13, Fig. 15 is a view of the applicator part shown in Fig. 14 as seen from arrow G, and Fig. 16 is a view showing how the impregnated body is attached to and detached from the applicator part of a brush-type applicator according to the third embodiment of the present invention. In Figs. 13 to 16, members and parts corresponding to those previously described are designated by the same reference numerals, and repeated explanations will be omitted where appropriate.

[0039] 13 to 16, the brush-type applicator 40 according to the third embodiment of the present invention has a base 21, multiple comb teeth 22, multiple bridging portions 23, impregnated body 24, and stopper portion 25 that are basically similar in configuration to the brush-type applicator 1 according to the first embodiment and the brush-type applicator 30 according to the second embodiment. However, the brush-type applicator 40 according to the third embodiment differs from the brush-type applicator 1 according to the first embodiment and the brush-type applicator 30 according to the second embodiment in the configuration of the opening / closing portion 26.

[0040] 13, 14, and 15, the open-close section 26 in the brush-type applicator 40 according to the third embodiment has a pair of open-close section pillars 26i provided adjacent to each row of comb teeth 22 on the other end side of the base 21, an open-close section bridge 26j connected at one end to one of the open-close section pillars 26i and at the other end to the other open-close section pillar 26i, and a lid 26m rotatably connected to the other end of the base 21 by a hinge 26k and capable of opening and closing an opening defined by the pair of open-close section pillars 26i and the open-close section bridge 26j. That is, in the third embodiment, the open-close section 26 is gate-shaped with an opening, and the opening is configured to be openable and closable by the lid 26m. In this third embodiment, the opening / closing body 26 is provided with an opening / closing section bridge portion 26j that is connected at one end to one opening / closing section pillar portion 26i and at the other end to the other opening / closing section pillar portion 26i, but it is also possible to configure the opening / closing section bridge portion 26j to be omitted and an opening to be formed between a pair of opening / closing section pillar portions 26i.

[0041] The lid portion 26m is integrally provided with a pair of locking claws 26n, and these locking claws 26n engage with the corresponding opening / closing unit pillars 26i, so that the lid portion 26m comes into contact with the opening / closing unit pillars 26i and the opening / closing unit bridge 26j, thereby holding the opening defined by the pair of opening / closing unit pillars 26i and the opening / closing unit bridge 26j in a closed state. The lid portion 26m then closes the opening, placing the opening / closing unit 26 in a held state. When the opening / closing unit 26 is in the held state, the other end 24b of the impregnation body 24 faces the lid portion 26m, so that the impregnation body 24 can be held on the base 21. On the other hand, as shown in Figure 16, when the lid portion 26m is rotated around the hinge 26k, the opening defined by a pair of pillar portions 26i for the opening / closing portion and bridge portion 26j for the opening / closing portion is opened, and the opening / closing portion 26 is placed in an open state, and the impregnated body 24 can be inserted into or pulled out from the multiple bridging portions 23 along the longitudinal direction of the base 21 from the side of the opening / closing portion 26.

[0042] In this way, with the brush-type applicator 1 according to the third embodiment, by closing the lid portion 26m and placing the opening / closing portion 26 in a holding state, the impregnated body 24 can be securely held on the base 21, and by opening the lid portion 26m and placing the opening / closing portion 26 in an open state, the impregnated body 24 can be attached to and detached from the applicator portion 20 from the other end side of the base 21.

[0043] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0044] For example, in the above embodiment, the shapes of the base 21, the plurality of comb teeth 22, the plurality of bridging portions 23, the impregnated body 24, the stopper portion 25 and the opening / closing portion 26 are not limited to the specific shapes described above and can be changed as appropriate.

[0045] Furthermore, in the above embodiment, the bridge portion 23b of one or more of the multiple bridging portions 23 may have a shape similar to the inverted portion 26b of the opening / closing portion 26 according to the first embodiment shown in Figures 5 and 6, so that it is connected at one end to one of the pillar portions 23a so as to be rotatable in a direction approaching and moving away from the base 21, and connected at the other end to the other pillar portion 23a so as to be rotatable in a direction approaching and moving away from the base 21, and is configured so as to be bendable at the center in a direction approaching and moving away from the base 21. This allows the opening / closing section 26 to be in an open state, while the bridge sections 23b of one or more bridging sections 23 are bent such that their central portions are away from the base 21 (a state corresponding to the open state of the opening / closing section 26 or the inverted section 26b), thereby preventing the impregnated body 24 from getting caught on the bridge sections 23b and making it easier to attach and detach the impregnated body 24 to the application section 20.Furthermore, by keeping the opening / closing section 26 in a holding state, while the bridge sections 23b of one or more bridging sections 23 are bent such that their central portions are closer to the base 21 (a state corresponding to the holding state of the opening / closing section 26 or the inverted section 26b), the bridge sections 23b are pressed against the impregnated body 24, making it possible to more securely hold the impregnated body 24 by the one or more bridging sections 23.
