[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed example of the configuration of a brush-type applicator according to one embodiment of the present invention will now be described with reference to the drawings.

[0014] As shown in FIG. 1, a brush-type applicator 1 according to one embodiment of the present invention has a grip part 10 and an applicator part 20.

[0015] The grip part 10 is configured in the shape of a cap having a top wall 11 and a peripheral wall 12, and is designed so that it can be screwed onto the mouth part 2a of the container body 2 at the peripheral wall 12. The brush-type applicator 1 is attached to the container body 2 by screwing the peripheral wall 12, i.e., the grip part 10, onto the mouth part 2a of the container body 2, and together with the container body 2, it constitutes the applicator container 3.

[0016] Container body 2 can contain a liquid application product such as mascara or hair dye. When brush-type applicator 1 is attached to container body 2, application part 20 is disposed inside container body 2. Container body 2 may be configured with opening 2a provided with a scraping part 2b for scraping the application product adhering to applicator part 20.

[0017] As shown in FIGS. 1 and 2, the applicator part 20 includes a rod part 21, a base 22, a plurality of comb teeth 23, a plurality of bridging parts 24, an impregnating body 25, and a stopper part 26.

[0018] The rod portion 21 is cylindrical, and one end of the rod portion 21 is attached to the grip portion 10. In this embodiment, the rod portion 21 is made of synthetic resin, and has a cylindrical rod main body portion 21a centered on the axis O, and a cylindrical fitting portion 21b that is integrally formed on one end of the rod main body portion 21a and has a larger diameter than the rod main body portion 21a, and is attached to the grip portion 10 by fitting the fitting portion 21b into the inside of the grip portion 10. The inside of the rod main body portion 21a forms a hole 21c that has a circular cross section.

[0019] The rod portion 21 may be configured to have an intermediate cylindrical portion 21d integrally provided between the rod main body portion 21a and the fitting portion 21b, the intermediate cylindrical portion 21d having a diameter larger than that of the rod main body portion 21a and smaller than that of the fitting portion 21b. In this case, it is preferable to provide a reduced diameter portion 21e between the rod main body portion 21a and the intermediate cylindrical portion 21d, the diameter of which gradually decreases from the intermediate cylindrical portion 21d side toward the rod main body portion 21a side.

[0020] 2 and 3, the base 22 is long and has a semi-cylindrical shape with the same diameter as the rod portion 21 and centered on the axis O, and one end in the longitudinal direction is integrally connected to the other end of the rod portion 21. In this embodiment, the base 22 is made of synthetic resin and is formed integrally with the rod portion 21 by injection molding of the synthetic resin material. One surface of the base 22 facing in the thickness direction (the surface facing left in FIG. 1) is the application surface 22a.

[0021] As shown in FIGS. 1 and 2, the comb teeth 23 are arranged in two rows along the longitudinal direction of the base 22 (the vertical direction in FIG. 2) on both sides of the axis O of the base 22. The number of comb teeth 23 in one row is the same as the number of comb teeth 23 in the other row, and the arrangement of the comb teeth 23 in each row is also the same. In this embodiment, when viewed from the front as shown in FIG. 1, each comb tooth 23 has a mountain-like shape that gradually becomes thinner from the lower end, which is connected to the base 22, to the tip, which is away from the base 22, and is formed integrally with the base 22 from a synthetic resin material. Note that, for convenience, only some of the comb teeth 23 are labeled with reference numerals in FIGS. 1 and 2.

[0022] The plurality of bridging portions 24 are each provided on the base 22. Each of the plurality of bridging portions 24 is formed integrally with the base 22 from a synthetic resin material.

[0023] More specifically, as shown in FIGS. 1 to 3 , each of the bridging portions 24 includes a pair of pillars 24a between adjacent comb teeth 23 in each row, and a bridge portion 24b connecting the pillars 24a in one row to the pillars 24a in the other row. In this embodiment, the bridging portions 24 are arranged such that three comb teeth 23 are sandwiched between each other in each row. Furthermore, in this embodiment, in each bridging portion 24, the width of the pillars 24a at the portion connected to the base 22 is equal to the width of the comb teeth 23 at the portion connected to the base 22 when viewed from the side perpendicular to the longitudinal direction. Furthermore, the width of the pillars 24a at each bridging portion 24 gradually narrows slightly from the portion connected to the base 22 toward the upper end, and a sharp portion similar to the upper end of the comb teeth 23 is integrally formed at the upper end of the base. The bridge portion 24b is integrally connected to the base of each pillar 24a. Each of the bridging portions 24, together with the base 22, forms a circular opening. For convenience, in FIG. 1, only one bridging portion 24 is labeled with a reference numeral, and in FIG. 2, only the post portion 24a and the bridge portion 24b of one bridging portion 24 are labeled with a reference numeral.

[0024] The impregnated body 25 is formed into a rod shape using a material capable of impregnating a liquid coating material, such as a sponge or a foam material such as polyurethane foam. In this embodiment, the cross-sectional shape of the impregnated body 25 perpendicular to the longitudinal direction is circular, corresponding to the circular opening defined by the hole 21c of the rod portion 21 and the base 22 and the bridging portion 24. That is, in this embodiment, the impregnated body 25 is in the shape of a round rod. A portion of the impregnated body 25 (in this embodiment, approximately half of one side in the longitudinal direction) is disposed inside the rod main body portion 21a of the rod portion 21, i.e., inside the hole 21c, and the other portion (in this embodiment, approximately half of the other side in the longitudinal direction) is inserted into the respective openings of the multiple bridging portions 24 between the two rows of comb teeth 23 and disposed on the coating surface 22a of the base 22. Note that the impregnated body 25 may have other shapes, such as a rectangular rod shape.

[0025] The outer diameter of the impregnated body 25 is preferably the same as the inner diameter of the hole 21c of the rod portion 21 and the inner diameter of the openings of the multiple bridging portions 24, but it may be slightly smaller or larger.

[0026] The stopper portion 26 is provided integrally with the other end of the base 22 opposite the longitudinal end of the rod portion 21, and faces the longitudinal end face of the impregnation body 25. This restricts the movement of the impregnation body 25 in the direction away from the gripping portion 10 (downward in Figures 1 and 2) by the stopper portion 26. In this embodiment, the stopper portion 26 abuts against the longitudinal end face of the impregnation body 25, but there may be a slight gap between the stopper portion 26 and the longitudinal end face of the impregnation body 25.

[0027] On the other hand, as shown in FIG. 1, the gripping portion 10 is provided with a pressure bar 13 to restrict movement of the impregnated body 25 in a direction approaching the gripping portion 10 (upward in FIGS. 1 and 2). In this embodiment, the pressure bar 13 has a round rod shape whose cross section perpendicular to the axis O is circular with the axis O at its center and whose outer diameter is approximately the same as the inner diameter of the hole 21c of the rod portion 21 so as to seal the hole 21c, and is provided integrally with and connected to the inner surface of the top wall 11 of the gripping portion 10. When the rod portion 21 is attached to the gripping portion 10, a portion of the tip side of the pressure bar 13 is inserted into the hole 21c of the rod main body portion 21a, and faces the longitudinal end face of the impregnated body 25 inside the hole 21c that faces the gripping portion 10. As a result, the pressure bar 13 restricts movement of the impregnated body 25 in a direction approaching the gripping portion 10 (upward in FIGS. 1 and 2). In this embodiment, the pressure bar 13 abuts against the longitudinal end face of the impregnated body 25, but there may be a slight gap between the pressure bar 13 and the longitudinal end face of the impregnated body 25.

[0028] In this way, the impregnated body 25 is held by the rod portion 21 and the base 22 by having its movement away from the holding portion 10 restricted by the stopper portion 26 and its movement toward the holding portion 10 restricted by the pressure rod 13.

[0029] The brush-type applicator 1 of this embodiment, which has such a configuration, can apply a liquid coating material to an object to be coated while combing the object with the multiple comb teeth 23 while the liquid coating material is impregnated into the impregnating body 25.

[0030] As shown in Fig. 4, the brush-type applicator 1 having the above configuration can be assembled in the following procedure. First, before attaching the rod portion 21 to the grip portion 10, the impregnation body 25 is inserted into the hole 21c of the rod main body portion 21a from the side of the fitting portion 21b, through the intermediate cylindrical portion 21d and the reduced diameter portion 21e. In this embodiment, since the rod portion 21 is provided with the intermediate cylindrical portion 21d and the reduced diameter portion 21e, the impregnation body 25 can be easily inserted into the hole 21c by being guided by the intermediate cylindrical portion 21d and the reduced diameter portion 21e.

[0031] Next, fitting portion 21b is fitted into grip portion 10, and rod portion 21 is attached to grip portion 10. When rod portion 21 is attached to grip portion 10, impregnation body 25 is pressed by pressure rod 13 toward stopper portion 26, and moves to a position where its longitudinal end face faces stopper portion 26. As a result, brush-type applicator 1 is assembled in a state where impregnation body 25 is disposed between rod main body portion 21a and base 22, and one longitudinal end face faces presser rod 13, and the other longitudinal end face faces stopper portion 26, as shown in FIG.

[0032] On the other hand, when removing the impregnated body 25 from the rod main body portion 21a and the base 22, the fitting portion 21b is released from the grip portion 10, the rod portion 21 is removed from the grip portion 10, and then the impregnated body 25 is pulled out from the side of the fitting portion 21b and removed.

[0033] As described above, in the brush-type applicator 1 according to this embodiment, the applicator part 20 is configured to have a cylindrical rod part 21 attached to the grip part 10 at one end, a long base 22 having a plurality of comb teeth 23 arranged in two rows along the longitudinal direction and one end of which is connected integrally to the other end of the rod part 21, an impregnated body 25 having a portion disposed inside the rod part 21 and another portion disposed on the base 22 between the two rows of comb teeth 23, and a stopper part 26 provided at the other end of the base 22 and facing the impregnated body 25, and the grip part 10 is configured to have a pressure rod 13 inserted into the rod part 21, so that the impregnated body 25 can be easily attached to the applicator part 20.

[0034] Furthermore, in the brush-type applicator 1 according to this embodiment, the impregnated body 25 is arranged on the rod portion 21 in addition to the base 22, and therefore the length of the impregnated body 25 can be made longer compared to a configuration in which the impregnated body 25 is arranged only on the base 22. This increases the amount of the substance to be applied that the impregnated body 25 can impregnate, thereby increasing the usage time of the applicator portion 20 and the area over which the applicator portion 20 can continuously apply the substance to be applied.

[0035] Furthermore, in the brush-type applicator 1 according to this embodiment, the outer diameter of the pressure bar 13 is approximately the same as the inner diameter of the hole 21c, so that the pressure bar 13 can seal the hole 21c, thereby preventing the application material impregnated in the impregnated body 25 from flowing into the inside of the grip portion 10.

[0036] Furthermore, in the brush-type applicator 1 of this embodiment, the base 22 is provided with a plurality of bridging portions 24, each having a pair of pillar portions 24a provided between adjacent comb teeth 23 in each row, and a bridge portion 24b connecting the pillar portions 24a in one row to the pillar portions 24a in the other row.Therefore, these bridging portions 24 prevent the impregnated body 25 from moving in a direction away from the application surface 22a of the base 22, allowing the impregnated body 25 to be more securely held on the base 22.

[0037] Fig. 5 is a cross-sectional front view of a brush-type applicator according to a modified example attached to a container body, and Fig. 6 is a cross-sectional front view of a brush-type applicator according to a modified example with the operating part pushed toward the rod part. In Fig. 5 and Fig. 6, the same reference numerals are appropriately used to designate the above-described members and parts.

[0038] As shown as a modified example in Figure 5, the brush-type applicator 1 of this embodiment may be configured so that the gripping portion 10 is provided with an operating portion 14 that can be pushed toward the rod portion 21, and when the operating portion 14 is pushed toward the rod portion 21, the pressure rod 13 is pushed by the operating portion 14, and the impregnated body 25 is compressed between the pressure rod 13 and the stopper portion 26.

[0039] More specifically, operating portion 14 is cylindrical with a top, and includes top wall 14a having a smaller diameter than top wall 11 of grip portion 10 and peripheral wall 14b having a smaller diameter than peripheral wall 12 of grip portion 10, and is disposed inside through-hole 11a provided in top wall 11 of grip portion 10. Operating portion 14 is movable along axis O between an initial position (position shown in FIG. 5) in which annular claw portion 14c provided on peripheral wall 14b is engaged with top wall 11, and a pushed-in position (position shown in FIG. 6) in which operating portion 14 is pushed from the initial position toward rod portion 21, i.e., toward the inside of grip portion 10.

[0040] A spring 15 is disposed between the top wall 14a of the operating portion 14 and the fitting portion 21b of the rod portion 21, and the operating portion 14 is biased by the spring 15 toward the initial position.

[0041] A round rod-shaped drive unit 14d extending along axis O is integrally provided on the underside of top wall 14a. Meanwhile, presser bar 13 has an outer diameter smaller than the inner diameter of hole 21c, and is configured such that a cylindrical piston unit 16 that slides along the inner circumferential surface of intermediate cylinder unit 21d of rod unit 21 is integrally provided on the end of presser bar 13 on the gripping unit 10 side. Drive unit 14d is fitted and fixed inside piston unit 16, thereby connecting presser bar 13. It should be noted that drive unit 14d may be configured to be formed integrally with presser bar 13.

[0042] In this modified brush-type applicator 1, the impregnated body 25 can be easily attached to the applicator part 20, similarly to the one shown in FIG.

[0043] Furthermore, in brush-type applicator 1 of this modified example, as shown in Figure 6, when operating section 14, which is in the initial position, is pushed in by the user and pushed toward rod section 21, presser bar 13 is pushed by drive section 14d of operating section 14 and moves toward stopper section 26 (downward in Figure 6), compressing impregnated body 25 between presser bar 13 and stopper section 26. Therefore, with brush-type applicator 1 of this modified example, by pushing in operating section 14, the application substance impregnated in impregnated body 25 can be effectively exuded from impregnated body 25 at the base 22, allowing the application substance to be efficiently applied to the object to be applied.

[0044] In brush-type applicator 1 of this modified example, the outer diameter of presser bar 13 is smaller than the inner diameter of hole 21c, and piston portion 16 is configured to slide on intermediate cylindrical portion 21d, so that rattle of presser bar 13 is suppressed when operating portion 14 is pushed in, making it possible to perform the pushing operation more easily. Furthermore, since piston portion 16 is provided that slides on intermediate cylindrical portion 21d, it is possible to prevent the application material impregnated in impregnation body 25 from flowing into the inside of grip portion 10.

[0045] When the pushing operation of the operating part 14 is released, the operating part 14 returns to its initial position due to the spring force of the spring 15, and the impregnation body 25 returns to its original shape.

[0046] 7 is a front view of an application part according to a modified example, FIG. 8 is a side view of the application part shown in FIG. 7, FIG. 9 is a cross-sectional view taken along line BB in FIG. 8, FIG. 10 is a cross-sectional view taken along line CC in FIG. 8, and FIG. 11 is a diagram showing the state of the pusher piece during molding. Note that in FIGS. 7 to 11, the same symbols are used appropriately for the aforementioned members or parts.

[0047] As shown as a modified example in Figures 7 and 8, the application part 20 may be configured so that one end is supported by a support part 27 provided on the base 22 and the other end is rotatably connected to a stopper part 26, and has a push-in piece 28 arranged on the upper surface of the impregnated body 25 between two rows of comb teeth 23.

[0048] More specifically, the pusher piece 28 has an elongated shape with a length along the axis O that is approximately the same as that of the base 22 and a width that is narrower than that of the base 22. In this modified example, the protruding height of the stopper portion 26 from the application surface 22a of the base 22 is approximately the same as the height of the impregnated body 25, and one end of the pusher piece 28 is rotatably connected to the upper end portion of the stopper portion 26.

[0049] As shown in Figures 7, 9, and 10, in this embodiment, the lower surface 28a of the pushing piece 28 facing the impregnation body 25 is curved to correspond to the outer peripheral surface of the impregnation body 25, and the entire lower surface 28a faces or abuts against the outer peripheral surface of the impregnation body 25. In contrast, the upper surface 28b of the pushing piece 28 facing away from the impregnation body 25 is approximately flat in a cross section perpendicular to the axis O and has a mountain-like shape with a vertex 28c, which is the highest part in the direction away from the base 22, at one end opposite the other end connected to the stopper portion 26 in the longitudinal direction along the axis O. In this embodiment, the vertex 28c is located between the bridging portion 24 closest to the rod portion 21 and the comb tooth 23 adjacent to the bridging portion 24 on the rod portion 21 side. In the front view shown in Figure 7, the height of the vertex 28c is slightly lower than the height of the multiple comb teeth 23.

[0050] 9, the support part 27 has a pair of pillar parts 27a and a pair of bridge parts 27b, each connected at one end to the corresponding pillar part 27a and having the other ends facing each other with a gap between them. The bridge part 27b locks the tip of the pusher piece 28 between the impregnation body 25 at the other end, thereby holding the pusher piece 28 in a state where its lower surface 28a is in contact with or close to the outer peripheral surface of the impregnation body 25.

[0051] The support portion 27 and the push-in piece 28 are formed integrally with the rod portion 21, the base 22, the comb teeth 23, the bridging portion 24 and the stopper portion 26 by injection molding a synthetic resin material.

[0052] As shown in Figure 11, during molding, the pushing piece 28 extends to the opposite side of the base 22, sandwiching the stopper portion 26, and from this state it rotates 180 degrees from the connection point with the stopper portion 26 as a starting point, and its tip is pushed through the gap between the pair of bridge portions 27b of the support portion 27 and between the pair of bridge portions 27b and the impregnated body 25, thereby keeping the lower surface 28a in contact with or close to the outer peripheral surface of the impregnated body 25.

[0053] In addition, in this modified example, in order to be able to rotate the push-in piece 28 so that the lower surface 28a comes into contact with the outer peripheral surface of the impregnation body 25, as shown in FIG. 10, each bridging portion 24 does not have a bridge portion 24b, but is connected to the corresponding pillar portion 24a at one end and has a pair of bridge portion 24c at the other end that face each other with a gap that allows the push-in piece 28 to pass through.

[0054] In the brush-type applicator 1 equipped with the applicator part 20 of this modified example, the impregnated body 25 can be easily attached to the applicator part 20 in the same manner as in the examples shown in FIGS.

[0055] Furthermore, with applicator unit 20 according to this modified example, when the liquid coating material is applied to the object to be coated while combing the object with multiple comb teeth 23 while the impregnated body 25 is impregnated with the liquid coating material, pushing pieces 28 are pushed by the object to be coated and rotate toward impregnated body 25 around the connecting portion with stopper portion 26, thereby compressing impregnated body 25. This allows the coating material impregnated in impregnated body 25 to effectively seep out of impregnated body 25 at the base 22 portion, allowing the coating material to be efficiently applied to the object to be coated.

[0056] Furthermore, in the application section 20 of this modified example, the pushing piece 28 is formed in a mountain shape with a vertex portion 28c, which is the part that is highest in the direction away from the base 22 on the side supported by the support portion, so that when pressed by the object to be applied, the pushing piece 28 rotates more efficiently toward the impregnated body 25 around the connecting portion with the stopper portion 26, allowing the application material impregnated in the impregnated body 25 to seep out more effectively from the impregnated body 25 in the part of the base 22, and can be applied more efficiently to the object to be applied.

[0057] 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.

[0058] For example, in the above embodiment, the shapes of the rod portion 21, the base 22, the plurality of comb teeth 23, the plurality of bridging portions 24, the impregnated body 25, the stopper portion 26 and the pressure rod 13 are not limited to the specific shapes described above and can be changed as appropriate.
