Mode for Carrying Out the Invention

[0017] Hereinafter, with reference to the drawings, the coating container 100 according to the first embodiment of the present disclosure will be described. The coating container 100 according to the present embodiment includes a container body 10 having a storage space S for the content, a mounting cap 20 fixed to the mouth portion 11 of the container body 10, a cylindrical column portion 30 that is mounted on the container body 10 by the mounting cap 20 and forms an internal flow path R for guiding the content in the tip direction, and a coating member 40 having a nozzle cylinder 41 and a brush portion 43 for discharging the content and mounted on the cylindrical column portion 30. The cylindrical column portion 30 and the coating member 40 constitute the coating tool 50 of the present embodiment.

[0018] In the present embodiment, the container body 10, the mounting cap 20, and the cylindrical column portion 30 are arranged such that their respective central axes are on the same axis. In the present embodiment, this common axis is referred to as the container axis O, and the direction along the container axis O is the vertical direction. Also, along the vertical direction, the side where the coating tool 50 is located is referred to as the upper side, and the side where the container body 10 is located is referred to as the lower side. Further, in a plan view, the direction intersecting the container axis O is referred to as the radial direction, and the direction of orbiting around the container axis O is referred to as the circumferential direction.

[0019] The container body 10 of this example has a cylindrical mouth portion 11, a cylindrical body portion 12 connected to the lower side of the mouth portion 11, and a bottom portion 13 closing the lower end portion of the body portion 12, and the inside thereof serves as a storage space S for the contents. On the outer peripheral surface of the mouth portion 11, a male screw is provided for screw-engagement with a mounting cap 20 described later.

[0020] The body portion 12 is cylindrical and has squeezable flexibility. Note that it may be a spray container capable of discharging the contents by pressing a coating tool 50 or the like. The shape of the container body 10 is not limited to the illustrated example and can be changed as appropriate. The bottom portion 13 is configured such that the coating container 100 can be placed on a horizontal surface in the upright posture shown in FIG. 1.

[0021] The mounting cap 20 has a mounting cylinder portion 21 held on the outer peripheral side of the mouth portion 11 and a reduced-diameter upper peripheral wall 22 extending further upward from the upper end portion of the mounting cylinder portion 21. The mounting cylinder portion 21 of the present embodiment has an internal female screw portion formed on the inner surface and can be screw-engaged with the male screw portion formed on the outer surface of the mouth portion 11 of the container body 10. Further, as shown in FIG. 1, the mounting cylinder portion 21 is provided with vertical ribs 21a extending in the vertical direction on the outer surface, and is configured such that the user can easily remove the mounting cap 20 from the container body 10 to perform filling of the contents or the like. Instead of screw-engagement, for example, the mounting cap 20 may be fixed to the container body 10 by undercut engagement of annular protrusions provided on both the mouth portion 11 and the mounting cylinder portion 21 with each other.

[0022] The cylinder column portion 30 is a cylindrical member extending in the vertical direction in FIG. 1 and guiding the contents in the tip direction (the upward direction in FIG. 1). As shown in FIG. 3, the cylinder column portion 30 forms an internal flow path R inside for guiding the contents accommodated in the container body 10 to the coating member 40. The cylinder column portion 30 can be mounted on the container body 10, for example, by sandwiching a flange portion provided at the lower end portion and protruding radially outward between the top wall of the mounting cylinder portion 21 and the upper end portion of the mouth portion 11.

[0023] As shown in Fig. 5B, the cylindrical column part 30 has a peripheral wall 31 that partitions and forms an internal flow path R. On the side surface of the peripheral wall 31 on the side where the coating member 40 described later is mounted, there are a fitting recess 32a into which the base end part 41b of the nozzle cylinder 41 is fitted, a communication hole 31b provided at the bottom of the fitting recess 32a and communicating the internal flow path R with the nozzle flow path N, and an engaging protrusion 33 that engages with an undercut of a clamping plate 47 connected to the brush part 43. As shown in Fig. 3, the fitting recesses 32a and the communication holes 31b are provided at equal intervals in the vertical direction in the same number as the number of nozzle cylinders 41. On the other hand, as shown in Fig. 2, the engaging protrusions 33 are provided at two positions in the vertical direction, and a total of four engaging protrusions 33 are provided including the engaging protrusion 33 provided on the opposite side (the upper side in Fig. 5B) not shown in Fig. 2. By the engaging protrusion 33 engaging with an undercut engaging hole 47a provided in the clamping plate 47 of the coating member 40, the coating member 40 is fixed to the cylindrical column part 30 in a detachable state.

[0024] As shown in Figs. 2 to 5B, the coating member 40 is provided so as to protrude from the side surface of the cylindrical column part 30, and includes a nozzle cylinder 41 that discharges the content to the outside, and a brush part 43 provided adjacent to the nozzle cylinder 41 in the horizontal direction (the direction perpendicular to the paper surface in Fig. 2, the left - right direction in Fig. 4, and the up - down direction in Fig. 5A).

[0025] The "brush part 43 provided adjacent to the nozzle cylinder 41 in the horizontal direction" is not limited to the case where the brush part 43 is arranged adjacent to the exact side of the nozzle cylinder 41 as shown in Fig. 4, but also includes the case where the brush part 43 is arranged adjacent to the nozzle cylinder 41 with a slight deviation in the up - down direction. Also, as shown in Fig. 4, additional brush parts 43 may be arranged at the up - down position between the brush parts 43 arranged adjacent to the exact side of the nozzle cylinder 41.

[0026] As shown in FIG. 5B, the nozzle cylinder 41 has its base end portion 41b fitted and fixed in a fitting recess 32a formed in the nozzle fixing portion 32 of the cylinder column portion 30. A communication hole 31b is formed at the bottom of the fitting recess 32a. With this configuration, the internal flow path R formed inside the cylinder column portion 30 communicates with the outside through the communication hole 31b, the nozzle flow path N, and the nozzle hole 41a.

[0027] As shown in FIGS. 5A and 5B, the brush portion 43 is provided adjacent to the nozzle cylinder 41 in the horizontal direction (perpendicular to the paper surface in FIG. 2, the left - right direction in FIG. 4, and the up - down direction in FIG. 5A). As shown in FIG. 5B, the brush portion 43 asymptotically approaches the nozzle cylinder 41 toward the tip of the brush portion 43, abuts on the nozzle cylinder 41 near the tip portion, and further extends beyond the tip portion.

[0028] With the above - described configuration, the region surrounded by the tip side of the brush portion 43 and the tip portion of the nozzle cylinder 41 forms a holding region K for holding the content (see FIG. 5B). That is, the content in the accommodation space S pumped upward by squeezing the body portion 12 of the container body 10 in FIG. 1 is discharged from the nozzle hole 41a through the internal flow path R of the cylinder column portion 30, the communication hole 31b, and the nozzle flow path N, and is held in the holding region K of FIG. 5B (see FIG. 7).

[0029] In the example shown in FIGS. 5A and 5B, the length of the nozzle cylinder 41 in the longitudinal direction (the left - right direction in FIGS. 5A and 5B) is configured to be longer than half of the length of the brush portion 43 in the longitudinal direction. With this configuration, the holding region K can be formed in a region closer to the tip of the brush portion 43. In the present embodiment, as shown in FIG. 5B, since the discharged content is configured to be held in the holding region K close to the tip of the brush portion 43, when the application member 40 is pressed against the user's hair with the content held in the holding region K, the content can reach the more root part of the hair. Therefore, it is possible to easily apply the content to the root part of the hair.

[0030] The coating member 40 according to this embodiment has the shape shown in FIG. 6A alone and can be formed by, for example, injection molding. That is, in the state of the member alone, the coating member 40 includes a cylindrical nozzle cylinder 41, a brush part 43 arranged substantially parallel to the nozzle cylinder 41 on both sides of the nozzle cylinder 41, and a connecting arm 45 that extends in a horizontal direction orthogonal to the longitudinal direction of the nozzle cylinder 41 on the proximal end side of the nozzle cylinder 41 and connects the nozzle cylinder 41 and the brush part 43, and a clamping plate 47 that extends further rearward (the right side in FIG. 6A) from the proximal end part of the brush part 43.

[0031] As shown in FIG. 6A, the connecting arm 45 is provided with a hinge part 45a that can be bent so that the tip part (the left end part in FIG. 6A) of the brush part 43 rotates in a direction approaching the nozzle cylinder 41 at a position closer to the nozzle cylinder 41. Further, the clamping plate 47 is connected to the brush part 43 via a thin part 46.

[0032] When the coating member 40 shown in FIG. 6A is moved in the direction of the white arrow in FIG. 6B and attached to the cylindrical column part 30, first, the engaging protrusion 33 of the cylindrical column part 30 fits into the engaging hole 47a provided in the clamping plate 47 (the state in FIG. 6B). In this state, although the brush part 43 is fixed to the cylindrical column part 30, for the nozzle cylinder 41, the proximal end part 41b is not yet completely fitted into the fitting recess 32a.

[0033] When the nozzle cylinder 41 is further pushed in the direction of the cylinder column part 30 from the state of FIG. 6B, the base end part 41b of the nozzle cylinder 41 is further deeply fitted into the fitting recess 32a, and the side surface of the connecting arm 45 on the side of the cylinder column part 30 abuts against the inclined surface 34 provided on the cylinder column part 30. Then, as shown in FIG. 6C, since the connecting arm 45 inclines along the inclined surface 34, the brush part 43 connected to one end of the connecting arm 45 inclines so as to approach the nozzle cylinder 41 toward the tip. In the present embodiment, a hinge part 45a is provided at a position of the connecting arm 45 closer to the nozzle cylinder 41, and the brush part 43 and the holding plate 47 are connected by a thin wall part 46. With this configuration, when the nozzle cylinder 41 is pushed in, the brush part 43 can easily rotate around the hinge part 45a and the thin wall part 46 extends, so that the brush part 43 can approach the nozzle cylinder 41 toward the tip.

[0034] In the present embodiment, a coating member 40 in which the nozzle cylinder 41 and the brush part 43 are arranged substantially in parallel as shown in FIG. 6A is formed by, for example, injection molding or the like, and when the coating member 40 is attached to the cylinder column part 30, the brush part 43 is configured to be deformed so as to approach the nozzle cylinder 41 side. With such a configuration, the coating member 40 can be formed without complicating the configuration of the mold for forming the coating member 40 and without using a process such as forced ejection, and the content holding region K can be formed relatively easily.

[0035] When using the coating container 100 having the above configuration, from the upright state of FIG. 1, the user holds and lifts, for example, the body part 12 of the container body 10, and presses the body part 12 inward while pressing the tip parts of the brush part 43 and the nozzle cylinder 41 of the coating member 40 against the hair. Due to the pressing of the body part 12 of the container body 10, the pressure in the accommodation space S of the container body 10 increases, so that the content accommodated in the accommodation space S is pressure-fed upward in FIG. 1 through the internal flow path R of the cylinder column part 30.

[0036] The content pumped up to the height region of the application member 40 passes through the communication hole 31b (see FIG. 3 etc.) provided in the cylindrical column portion 30, and is further discharged from the nozzle hole 41a via the nozzle flow path N of the nozzle cylinder 41. In the present embodiment, as shown in FIG. 7, the content discharged from the nozzle hole 41a is held in the holding region K close to the tip of the brush portion 43. In this way, when the application member 40 is pressed against the user's hair while the content is held in the holding region K, the content can reach the more root part of the hair. Therefore, it becomes possible to easily apply the content to the root part of the hair.

[0037] As described above, the present embodiment is an application container 100 including a container body 10 having a storage space S for the content and an applicator 50 attached to the mouth portion 11 of the container body 10. The applicator 50 has a cylindrical column portion 30 extending in the vertical direction and guiding the content in the tip direction, a nozzle cylinder 41 protruding from the side surface of the cylindrical column portion 30 and discharging the content to the outside, and a brush portion 43 provided adjacent to the nozzle cylinder 41 in the horizontal direction. The brush portion 43 is configured to approach the nozzle cylinder 41 toward the tip of the brush portion 43 and extend beyond the tip of the nozzle cylinder 41. By adopting such a configuration, when the application member 40 is pressed against the user's hair while the content is held in the holding region K formed by the nozzle cylinder 41 and the brush portion 43, the content can reach the more root part of the hair. Therefore, it becomes possible to easily apply the content to the root part of the hair.

[0038] Further, in the present embodiment, the brush portion 43 is connected at the proximal end side by a connecting arm 45 extending in a substantially horizontal direction with respect to the nozzle cylinder 41. Due to the elastic deformation of the connecting arm 45, the brush portion 43 rotates around the connecting arm 45 with respect to the nozzle cylinder 41 in a substantially horizontal plane, so that the brush portion 43 is configured to approach the nozzle cylinder 41 toward the tip of the brush portion 43. By adopting such a configuration, the configuration of the mold for forming the application member 40 having the nozzle cylinder 41 and the brush portion 43 is not complicated, and the application member 40 can be formed without using processes such as forced extraction, while the holding region K for the content can be formed relatively easily.

[0039] Further, in the present embodiment, the connecting arm 45 is configured to have a hinge portion 45a that can be bent in a direction in which the tip of the brush portion 43 approaches the nozzle cylinder 41. By adopting such a configuration, the connecting arm 45 can be easily bent around the hinge portion 45a, so that the connecting arm 45 can be more easily elastically deformed and the brush portion 43 can be gradually brought closer to the nozzle cylinder 41 toward the tip.

[0040] Further, in the present embodiment, a sandwiching plate 47 that extends from the base end portion of the brush portion 43 in the direction of the cylindrical column portion 30 and sandwiches the cylindrical column portion 30 from the outside is connected to the brush portion 43. The cylindrical column portion 30 is configured to have a fitting recess 32a into which the base end portion 41b of the nozzle cylinder 41 is fitted and an engaging protrusion 33 that engages with an undercut in an engaging hole 47a formed in the sandwiching plate 47. By adopting such a configuration, the application member 40 can be fixed at a plurality of locations by the engaging protrusion 33 and the fitting recess 32a, and the posture of the brush portion 43 with respect to the nozzle cylinder 41 can be stabilized.

[0041] Further, in the present embodiment, the cylindrical column portion 30 is provided with an inclined surface 34 that inclines in the direction of the cylindrical column portion 30 from the brush portion 43 toward the nozzle cylinder 41. When the connecting arm 45 abuts against the inclined surface 34, the brush portion 43 is configured to gradually approach the nozzle cylinder 41 toward the tip of the brush portion 43. By adopting such a configuration, since the inclination of the connecting arm 45 in the horizontal plane is determined by abutting against the inclined surface 34, the posture of the brush portion 43 connected to one end of the connecting arm 45 can be further stabilized.

[0042] Further, in the present embodiment, the brush portion 43 is configured to abut against the tip portion of the nozzle cylinder 41. By adopting such a configuration, even when the viscosity of the content is low, it is possible to suppress the content from leaking out of the holding region K through the gap between the nozzle cylinder 41 and the brush portion 43, so that the content can be more reliably applied to the root portion of the hair.

[0043] In addition, in the present embodiment, the longitudinal length of the nozzle cylinder 41 is configured to be longer than half of the longitudinal length of the brush portion 43. By adopting such a configuration, the holding region K of the content can be arranged closer to the tip of the brush portion 43, so that the content can be more reliably applied to the root portion of the hair.

[0044] Next, the application container 200 according to the second embodiment of the present disclosure will be described with reference to FIGS. 8 and 9. The application container 200 of the present embodiment is approximated to the configuration of the first embodiment except that the brush portion 43 is adjacently arranged only on one side in the horizontal direction of the nozzle cylinder 41. Therefore, the differences from the first embodiment will be mainly described here.

[0045] The application member 150 used in the application container 200 according to the present embodiment is provided to protrude from the side surface of the cylindrical column portion 30 as shown in FIGS. 8 and 9, and includes a nozzle cylinder 41 that discharges the content to the outside, and a brush portion 43 that is provided adjacent to the nozzle cylinder 41 in the horizontal direction. As shown in FIG. 9, the brush portion 43 is provided only on one side in the horizontal direction of the nozzle cylinder 41 (the back side perpendicular to the paper surface in FIG. 8, the upward direction in FIG. 9). By adopting such a configuration, the user can directly confirm the content held in the holding region surrounded by the nozzle cylinder 41 and the brush portion 43 by observing the nozzle cylinder 41 from the side where the brush portion 43 is not provided. Therefore, since the content can be applied to the hair after confirming the amount of the content held in the holding region, it is possible to suppress the application of an inappropriate amount of content against the user's intention. Note that the present embodiment is suitable for discharging a content having a relatively high viscosity.

[0046] As described above, in the present embodiment, the brush portion 43 is configured to be adjacently provided only on one side in the horizontal direction of the nozzle cylinder 41. By adopting such a configuration, the content can be applied to the hair after confirming the amount of the content held in the holding region, so that it is possible to suppress the application of an inappropriate amount of content against the user's intention.

[0047] Although the present disclosure has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included within the scope of the present invention. For example, the functions included in each component can be rearranged so as not to be logically inconsistent, and a plurality of components can be combined into one or divided. It should be understood that these are also included within the scope of the present invention.

[0048] For example, in the first and second embodiments, as shown in FIG. 5B and the like, the cylindrical column portion 30 is configured to have a substantially cylindrical shape, but is not limited to this aspect. The cylindrical column portion 30 may be configured to have, for example, a square tube shape.

[0049] Also, in the first and second embodiments, as shown in FIGS. 3 and 8 for example, the brush portion 43 is configured in a comb-tooth shape, but is not limited to this aspect. For example, it may be a brush-shaped applicator having a large number of hair-like protrusions. The form of the brush portion 43 can be appropriately changed according to the content and the object to which the content is applied.

[0050] Also, in the first and second embodiments, the case of applying the content to the hair using the applicator 50 has been described, but is not limited to this aspect, and it is effective when efficiently applying the content to the root portion of an object other than the hair.
