[0001] The present invention relates to an application container.
Background Art
[0002] As one specific example of applying the content to the application part, for example, hair dyeing such as hair color or color treatment applied to hair can be mentioned. In hair dyeing, the content may be held by an application member and applied to the hair. However, for example, there is a concern about the loss of the application member or forgetting to prepare it. Also, depending on the configuration of the application part, it may be difficult to apply the content to a narrow part such as a fluff, for example. <An application container according to one aspect of the present invention comprises a container body for containing contents, a mouth member provided on the container body, and an application member detachably provided on the mouth member, wherein the mouth member has a first dispensing cylinder communicating with the inside of the container body and a support cylinder surrounding the first dispensing cylinder from the radially outer side, and the application member has a second dispensing cylinder detachably fitted to the first dispensing cylinder, a base portion formed in a flange shape protruding radially outward from the outer circumferential surface of the second dispensing cylinder and having a first surface and a second surface facing vertically, a first application portion protruding vertically from the first surface, and from the second surface upward The coating member comprises a second coating portion that protrudes downward and has a different configuration from the first coating portion, the coating member is formed to be attachable to the mouth member in both up and down directions, the base portion is detachably fitted into the support cylinder, each portion of the support cylinder facing each other in the radial direction has a recessed portion that opens upward and penetrates radially, the outer circumferential surface of the base portion is provided with two locking protrusions that protrude radially outward and are fitted into each of the recessed portions, and at least the portion of the support cylinder along the circumferential direction in which the recessed portions are formed is formed to be elastically deformable radially.
[0007] The coating member is formed to be attachable to the mouth member in both upward and downward directions, and the configurations of the first coating portion and the second coating portion, which protrude from the base portion in opposite directions in the upward and downward directions, are different from each other. Therefore, it is possible to attach the coating member to the mouth member with either the first or second coating portion protruding upward from the base portion and exposed to the outside, and the other protruding downward from the base portion and housed inside the support cylinder. As a result, the contents can be applied to the desired area using either the first or second coating portion without changing the relative position of the handle and the coating member, and the contents can be prevented from unintentionally adhering to the other of the first or second coating portion. The base portion of the coating member is detachably fitted into the support cylinder of the mouth member, and a recessed portion is formed in the support cylinder that opens upward and penetrates radially. A locking projection is provided on the outer circumferential surface of the base portion that protrudes radially outward and is fitted into the recessed portion. At least the portion of the support cylinder along the circumferential direction in which the recessed portion is formed is formed to be elastically deformable radially. Therefore, when the portion of the support cylinder along the circumferential direction in which the recessed portion is formed is elastically deformed radially inward, the bottom surface of the recessed portion slides against the locking projection, disengaging the locking projection from the recessed portion and allowing the base portion to be disengaged upward from the support cylinder, thereby allowing the coating member to be easily detached from the support cylinder. In this configuration, recessed portions are formed on each radially opposing part of the support cylinder, and two locking protrusions are provided on the outer circumferential surface of the base portion and fitted into each recessed portion. Therefore, by pressing the circumferential portions of the outer circumferential surface of the support cylinder, where the recessed portions are formed, toward each other in the radial direction, the coating member will detach from the support cylinder, thereby improving operability. Based on the above, it is possible to improve the operability when applying the contents to a desired area using the desired application part.
[0008] The upper and lower surfaces of the locking projection include a third surface supported by the bottom surface of the recessed portion and a fourth surface extending radially inward from the third surface, and each of the fourth surfaces formed on the upper and lower surfaces of the locking projection may extend in a direction that separates them vertically from each other as they move radially inward.
[0009] The upper and lower surfaces of the locking projection are provided with a third surface supported by the bottom surface of the recessed portion and a fourth surface extending radially inward from the third surface. Since the fourth surfaces formed on the upper and lower surfaces of the locking projection extend in a direction that separates them vertically from each other as they move radially inward, when the portion of the support cylinder along the circumferential direction in which the recessed portion is formed is elastically deformed radially inward, the bottom surface of the recessed portion pushes up the fourth surface of the locking projection by sliding radially inward, regardless of the vertical orientation of the coating member, and the coating member can be easily and reliably detached from the support cylinder.
[0010] The support cylinder may have a rectangular shape with a long side portion and a short side portion when viewed from above, and the recessed portion may be formed in the long side portion.
[0011] The support cylinder has a rectangular shape with a long side and a short side when viewed from above, and the recessed portion is formed on the long side of the support cylinder. Therefore, when the portion of the outer surface of the support cylinder along the circumferential direction where the recessed portion is formed is pressed radially inward, it is easier to elastically deform it, allowing the coating member to be easily and reliably detached from the support cylinder. [Effects of the Invention]
[0012] According to one aspect of the present invention, it is possible to improve the operability when applying contents to a desired area using a desired application part. [Brief explanation of the drawing]

[Figure 3] This is a cross-sectional view taken along the line III-III in Figure 1. [Figure 4] This is an explanatory diagram showing how to detach the coating member from the support cylinder. [Figure 5] Figure 1 shows the coating member attached to the nozzle member in an inverted orientation. [Figure 6] This is a cross-sectional view taken along the line VI-VI in Figure 5. [Figure 7] This is a cross-sectional view taken along the line VII-VII in Figure 5. [Modes for carrying out the invention]
[0014] A coating container according to one embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 2 and 3, and FIGS. 6 and 7, the coating container 1 according to the present embodiment includes a container body 11, a mouth member 12, and a coating member 13. The container body 11 has a cylindrical mouth portion 14, the mouth member 12 has a first pouring cylinder 15 and a support cylinder 16, and the coating member 13 has a second pouring cylinder 17. The mouth portion 14, the first pouring cylinder 15, the support cylinder 16, and the second pouring cylinder 17 are arranged coaxially with a common axis.
[0015] Hereinafter, this common axis is referred to as the container axis O, the mouth portion 14 side of the container body 11 along the container axis O is referred to as the upper side, the bottom side of the container body 11 is referred to as the lower side, and the direction along the container axis O is referred to as the vertical direction. The direction intersecting the container axis O as viewed from the vertical direction is referred to as the radial direction, and the direction orbiting around the container axis O as viewed from the vertical direction is referred to as the circumferential direction.
[0016] The container body 11 houses the content. The content is not particularly limited, and examples include hair dyes and the like. The container body 11 is not particularly limited, and examples include a tube container and a bottle container having a self-supporting bottom. A male screw portion is formed in a portion of the outer peripheral surface of the mouth portion 14 of the container body 11 that is located below the upper end portion. A movable plate 18 whose front and back surfaces face the vertical direction is provided in the mouth portion 14. A part of the outer peripheral surface of the movable plate 18 is connected to the inner peripheral surface of the mouth portion 14 via an elastically deformable hinge portion 19. As the content in the container body 11 flows upward, the movable plate 18 rotates upward around the hinge portion 19. Note that the movable plate 18 and the hinge portion 19 may not be provided.
[0017] The mouth member 12 is provided on the container body 11. In the illustrated example, the mouth member 12 is separate from the container body 11, but may be integrally formed with the container body 11. The mouth member 12 is screwed onto the mouth portion 14 of the container body 11, but may be undercut-fitted to the mouth portion 14. The mouthpiece member 12 has a roofed cylindrical main body cylinder 21 having an annular top wall 21a, a first pouring cylinder 15 communicating with the inside of the container main body 11, and a support cylinder 16 surrounding the first pouring cylinder 15 from the outside in the radial direction.
[0018] On the lower surface of the top wall 21a of the main body cylinder 21, a connecting cylinder 22 and a sealing cylinder 25 are formed. The mouth 14 is screwed inside the connecting cylinder 22. Note that the connecting cylinder 22 may be, for example, undercut-fitted to the mouth 14. The sealing cylinder 25 is disposed radially inward of the connecting cylinder 22 and is closely fitted externally to the upper end portion of the mouth 14. The first pouring cylinder 15 is formed in a cylindrical shape and projects upward from the inner peripheral edge portion of the top wall 21a.
[0019] The support cylinder 16 projects upward from the top wall 21a. The upper end portion of the support cylinder 16 is located above the upper end portion of the first pouring cylinder 15. As shown in FIGS. 1 and 3, and FIGS. 5 and 7, in the support cylinder 16, concave recessed portions 24 that open upward and penetrate in the radial direction are formed in respective portions facing each other in the radial direction. Among the inner surfaces of the concave recessed portions 24, the bottom surface located at the lower end and facing upward is a flat surface. At least the portion along the circumferential direction in which the concave recessed portions 24 are formed in the support cylinder 16 is formed to be elastically deformable in the radial direction. At least the portion along the circumferential direction in which the concave recessed portions 24 are formed in the support cylinder 16 is formed thinner than other portions.
[0020] When viewed from the vertical direction, the support cylinder 16 has a rectangular shape having a long side portion 16a and a short side portion 16b. The long side portion 16a has a protruding curved shape toward the outside in the radial direction when viewed from the vertical direction, but is not limited thereto and may extend, for example, linearly. [[ID=1&8]]Hereinafter, when viewed from the vertical direction, the direction in which the long side portion 16a extends is referred to as the first direction X, and the direction in which the short side portion 16b extends when viewed from the vertical direction is referred to as the second direction Y. <=
[0021] The recessed portion 24 is formed in the long side portion 16a of the support cylinder 16. The recessed portion 24 is provided along the entire length of the long side portion 16a of the support cylinder 16 in the first direction X, excluding both ends in that direction. Of the long side portion 16a of the support cylinder 16, only the portion along the circumferential direction in which the recessed portion 24 is formed is made thin and is elastically deformable in the radial direction. The long side portion 16a of the support cylinder 16 may be formed to be elastically deformable in the radial direction along its entire length in the first direction X, or the support cylinder 16 may be formed to be elastically deformable in the radial direction over its entire circumference, including the short side portion 16b.
[0022] The coating member 13 is detachably attached to the opening member 12. The coating member 13 is formed to be attachable to the opening member 12 in both upward and downward directions, as shown in Figures 1 and 5, Figures 2 and 6, and Figures 3 and 7, respectively. The coating member 13 comprises a second dispensing cylinder 17, a base portion 26, a first coating portion 27, and a second coating portion 28.
[0023] The second dispensing cylinder 17 is formed in a cylindrical shape and is detachably fitted to the first dispensing cylinder 15. Both ends of the second dispensing cylinder 17 in the vertical direction are formed to be detachably fitted separately to the upper end of the first dispensing cylinder 15. In the illustrated example, the second dispensing cylinder 17 is fitted into the first dispensing cylinder 15. On the outer circumferential surface of the second dispensing cylinder 17, both the upper and lower ends are formed separately, with projections 17a that protrude radially outward and extend circumferentially, and are detachably undercut-fitted into the first dispensing cylinder 15.
[0024] The base portion 26 is formed in a flange shape that protrudes radially outward from the outer circumferential surface of the second dispensing cylinder 17. The base portion 26 is detachably fitted into the support cylinder 16. In the illustrated example, the base portion 26 protrudes radially outward from the middle of the outer circumferential surface of the second dispensing cylinder 17 in the vertical direction, but it may also be provided at the ends in the vertical direction of the outer circumferential surface of the second dispensing cylinder 17. The base portion 26 abuts vertically against the upper end opening edge of the first dispensing cylinder 15.
[0025] The base portion 26, like the support cylinder 16, has a rectangular shape with a long side portion 26a and a short side portion 26b when viewed from above. The long side portion 26a of the base portion 26 extends in a first direction X when viewed from above and is fitted into the long side portion 16a of the support cylinder 16. The short side portion 26b of the base portion 26 extends in a second direction Y when viewed from above and is fitted into the short side portion 16b of the support cylinder 16.
[0026] The base portion 26 has a first surface 26c and a second surface 26d that face in the vertical direction. The first coating portion 27 protrudes vertically from the first surface 26c. The second coating portion 28 protrudes vertically from the second surface 26d and has a different configuration from the first coating portion 27. The first application section 27 and the second application section 28 are each composed of multiple comb teeth that protrude vertically from the base section 26. The first application section 27 has fewer thicker comb teeth than the second application section 28, so that the contents can be applied over a wide area. The second application section 28 has more thin comb teeth than the first application section 27, so that the contents can be applied precisely to a narrow area.
[0027] As shown in Figures 1 and 3, and Figures 5 and 7, the outer circumferential surface of the base portion 26 is provided with two locking projections 29 that protrude radially outward and are fitted into each recessed portion 24. The radially outer ends of the locking projections 29 protrude from the recessed portion 24 in the second direction Y, but this protrusion is not required. The upper and lower surfaces of the locking projection 29 include a third surface 29a supported by the bottom surface of the recessed portion 24, and a fourth surface 29b extending radially inward from the third surface 29a. The fourth surface 29b is connected to the outer circumferential surface of the base portion 26. Each of the fourth surfaces 29b formed on the upper and lower surfaces of the locking projection 29 extends in a direction that separates them vertically from each other as they move radially inward. The third surface 29a is a flat surface.
[0028] The central portions in the vertical direction of the locking projection 29, the base portion 26, and the second dispensing cylinder 17 are aligned with each other. Of the coating member 13, the locking projection 29, base portion 26, and second dispensing cylinder 17, which are the parts excluding the first coating portion 27 and the second coating portion 28, exhibit a symmetrical shape with respect to a straight line that passes through the vertical center of each of the locking projection 29, base portion 26, and second dispensing cylinder 17 and extends in the second direction Y, as shown in the vertical cross-sectional view along the second direction Y in Figures 3 and 7.
[0029] As described above, according to the coating container 1 of this embodiment, the coating member 13 is formed to be attachable to the mouth member 12 in both upward and downward directions, and the configurations of the first coating portion 27 and the second coating portion 28, which protrude from the base portion 26 in opposite directions in the upward and downward directions, are different from each other. Therefore, it is possible to attach the coating member 13 to the mouth member 12 with either the first coating portion 27 or the second coating portion 28 protruding upward from the base portion 26 and exposed to the outside, and the other protruding downward from the base portion 26 and housed inside the support cylinder 16.
[0030] This allows the contents to be applied to the desired area using either the first application section 27 or the second application section 28 without changing the relative position of the handle and the application member 13, and prevents the contents from unintentionally adhering to the other of the first application section 27 or the second application section 28.
[0031] The base portion 26 of the coating member 13 is detachably fitted into the support cylinder 16 of the mouth member 12. The support cylinder 16 has a recessed portion 24 that opens upward and penetrates radially. A locking projection 29 is provided on the outer circumferential surface of the base portion 26, which protrudes radially outward and is fitted into the recessed portion 24. At least the portion of the support cylinder 16 along the circumferential direction in which the recessed portion 24 is formed is formed to be elastically deformable radially. As shown in Figure 4, when the portion of the support cylinder 16 along the circumferential direction in which the recessed portion 24 is formed is elastically deformed radially, the bottom surface of the recessed portion 24 slides against the locking projection 29, causing the locking projection 29 to disengage from the recessed portion 24 and the base portion 26 to disengage upward from the support cylinder 16, the coating member 13 can be easily detached from the support cylinder 16.
[0032] In this configuration, the recessed portions 24 are formed on each radially opposing portion of the support cylinder 16, and two locking projections 29 are provided on the outer circumferential surface of the base portion 26 and fitted into each recessed portion 24. Therefore, by pressing the portions of the outer circumferential surface of the support cylinder 16 where the recessed portions 24 are formed in a direction that brings them radially closer together, the coating member 13 will detach from the support cylinder 16, thereby improving operability. Based on the above, it is possible to improve the operability when applying the contents to a desired area using the desired application part.
[0033] The upper and lower surfaces of the locking projection 29 are provided with a third surface 29a supported by the bottom surface of the recessed portion 24 and a fourth surface 29b extending radially inward from the third surface 29a. Since the fourth surfaces 29b formed on the upper and lower surfaces of the locking projection 29 extend in a direction that separates them vertically from each other as they move radially inward, as shown in Figure 4, when the portion of the support cylinder 16 along the circumferential direction in which the recessed portion 24 is formed is elastically deformed radially inward, the bottom surface of the recessed portion 24 pushes up the fourth surface 29b of the locking projection 29 by sliding radially inward, regardless of the vertical orientation of the coating member 13, and the coating member 13 can be easily and reliably detached from the support cylinder 16.
[0034] The support cylinder 16 has a rectangular shape with a long side portion 16a and a short side portion 16b when viewed from above, and the recessed portion 24 is formed in the long side portion 16a of the support cylinder 16. Therefore, when the portion of the outer surface of the support cylinder 16 along the circumferential direction where the recessed portion 24 is formed is pressed radially inward, it becomes easier to elastically deform the portion, and the coating member 13 can be easily and reliably detached from the support cylinder 16.
[0035] Furthermore, the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
[0036] For example, the upper and lower surfaces of the locking projection 29 may be formed flat over their entire length. The shape of the support cylinder 16 when viewed from above or below may be, for example, a square, a polygon, a circle, an oval, or the like. The first coating section 27 and the second coating section 28 are not limited to comb teeth as in the above embodiment, but may also be, for example, a brush or the like.
[0037] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above embodiments and modifications may be combined as appropriate. [Explanation of Symbols]
