Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments of a coating container according to the present invention will be described with reference to the accompanying drawings. In the following description, when referring to up and down, it means up and down of the coating container in an upright state, and means above and below the paper surface in FIGS. 1 to 6.

[0014] FIG. 1 is a front partial cross-sectional view showing a coating container 1 according to an embodiment of the present invention. The coating container 1 according to the present embodiment includes a container 2 that houses a content liquid C therein, and a cap 3 with an applicator that is detachably attached to the container 2. In the present embodiment, the content liquid C is a nail polish liquid, and the coating container 1 is a container for applying nail polish to the nails of a user.

[0015] The container 2 has a hollow cylindrical body portion 21 that can accommodate the content liquid C, and a mouth portion 22 that is continuously formed above the body portion 21 and has a reduced diameter compared to the body portion 21 and an open upper portion.

[0016] A helical thread 221 is formed along the circumferential direction on the outer periphery of the mouth portion 22.

[0017] The cap 3 with an applicator is composed of a cap portion 31 attached to the mouth portion 22 of the container 2, a volume change portion 32 attached to the cap portion 31 and being hollow and capable of changing volume, a hollow cylindrical shaft portion 33 continuously provided to the volume change portion 32 and having an opening 332a at the tip, and an applicator 34 attached in a manner that allows the content liquid C to communicate between the inside of the container 2 and the inside of the shaft portion 33 with respect to the opening 332a of the shaft portion 33.

[0018] The cap portion 31 is a cylindrical member with both upper and lower end portions being open ends, and a thread groove 311 that can be screwed with the thread 221 of the container 2 is formed on the inner peripheral surface of the lower end portion. A locking recess 312 is formed along the circumferential direction above the thread groove 311 of the cap portion 31. A protruding portion 313 protruding toward the inner side in the circumferential direction is formed at the upper end portion of the cap portion 31.

[0019] The volume change portion 32 is formed of a material such as an elastically deformable resin. In the present embodiment, the volume change portion 32 is an elastically deformable dome portion formed of three stages: an upper stage portion 321a, a middle stage portion 321b, and a lower stage portion 321c in order from above. By pressing down and restoring the volume change portion 32, the internal volume of the cap 3 with an applicator can be changed. A locking stage portion 321d, which is a fourth stage portion not involved in the volume change, is formed at the lower end portion of the volume change portion 32.

[0020] The shaft portion 33 is a hollow cylindrical member and is formed by a large-diameter portion 331 located directly below the volume change portion 32 and a small-diameter portion 332 that is continuous therewith while the inner diameter and the outer diameter are reduced below the large-diameter portion 331.

[0021] A stage portion 331a that is reduced in diameter along the circumferential direction is formed on the outer peripheral side of the upper end of the large-diameter portion 331. By sandwiching the locking stage portion 321d of the volume change portion 32 between this stage portion 331a and the protruding portion 313 of the cap portion 31, the volume change portion 32 is fixed to the cap portion 31 and the shaft portion 33.

[0022] Below the boundary between the large-diameter portion 331 and the small-diameter portion 332, a lower stepped portion 331b is formed by reducing the outer diameter. The attachment of the cap 3 with an applicator to the container 2 is performed while screwing the thread groove 311 formed in the cap portion 31 of the cap 3 with an applicator and the thread 221 of the container 2. When this lower stepped portion 331b abuts against the upper edge portion 223 of the mouth portion 22 of the container 2, the downward movement of the cap 3 with an applicator is restricted.

[0023] FIG. 2 is a plan view of the shaft portion 33 used in the coating container 1 according to the embodiment of the present invention. As shown in FIGS. 1 and 2, an upper stepped portion 335, which is a flange-shaped flat portion, is formed above the boundary between the large-diameter portion 331 and the small-diameter portion 332. From this upper stepped portion 335 along the inner peripheral wall of the large-diameter portion 331 to the vicinity of the upper end portion of the large-diameter portion 331, a reinforcing rib 336 is formed to reinforce the large-diameter portion 331 and regulate the press-deformable range of the volume change portion 32 within a predetermined range so that the press-change portion 32 can surely return to its original shape after deformation. In the present embodiment, four reinforcing ribs 336 are formed at equal intervals.

[0024] Returning to FIG. 1, a locking convex portion 334 is formed on the outer peripheral surface in the vicinity of the lower end portion of the large-diameter portion 331 along the circumferential direction. When this locking convex portion 334 engages with the locking concave portion 312 of the cap portion 31, the shaft portion 33 is fixed within the cap portion 31.

[0025] The small-diameter portion 332 is a cylindrical member having a smaller diameter than the large-diameter portion 331 continuously formed with the large-diameter portion 331. An opening 332a is formed at the lower end portion of the small-diameter portion 332. A pair of notches 332c facing each other with the applicator 34 interposed therebetween are provided on the lower end side peripheral wall portion 332b of the small-diameter portion 332 defining the opening 332a.

[0026] In the peripheral wall near the upper end of the small-diameter portion 332, an air hole 332d penetrating therethrough is formed. In a state where the cap 3 with an applicator is attached to the container 2, the air hole 332d is in a closed state due to the sealing projection 332e of the small-diameter portion 332 abutting against the inner peripheral wall of the mouth portion 22, and in a state where the cap 3 with an applicator is removed from the container 2, the air hole 332d is in an open state.

[0027] By the sealing projection 332e abutting against the inner peripheral wall of the mouth portion 22, it becomes possible to surely close the air hole 332d in a state where the cap 3 with an applicator is attached to the container 2.

[0028] In the opening 332a of the small-diameter portion 332, an applicator 34 is attached so as to be able to conduct the content liquid C between the inside of the container 2 and the inside of the shaft portion 33. The applicator 34 has an elastically deformable brush 341 inserted through a fixing plate 342 that fits into the inner peripheral wall of the shaft portion 33, and further, a portion of the brush 341 protruding from the fixing plate 342 toward the base end side (above the paper surface in FIG. 1) of the shaft portion 33 is bundled by a bundling tool 343.

[0029] The brush 341 is composed of a large number of elastically deformable resin hairs. The brush 341 can be elastically deformed so that most of it can protrude outward in the circumferential direction of the shaft portion 33 from the notch 332c of the shaft portion 33. In the present embodiment, a resin brush 341 is adopted, but the present invention is not limited thereto, and those formed of other materials such as animal hairs can also be preferably used.

[0030] FIG. 3 is a plan view showing a fixing plate 342 used in the coating container according to the embodiment of the present invention. The fixing plate 342 is a rounded plate-like member, and a brush hole portion 342b through which the brush 341 is inserted and bundled is formed in the central portion of the flat base member 342a, and a pair of through holes 342c through which the content liquid C can be conducted are provided around the brush hole portion 342b. This fixing plate 342 is fixed to the inner peripheral wall of the shaft portion 33 by fitting. In the present embodiment, as shown in FIG. 3, a pair of through holes 342c are provided facing each other in the left-right direction (longitudinal direction) of the base member 342a with the brush hole portion 342b interposed therebetween. However, in the present invention, the arrangement of the through holes 342c is not limited to this, and they may be provided facing each other in the up-down direction (shortitudinal direction). Further, in the present invention, the number of the through holes 342c is not limited to a pair (two), and may be one or three or more.

[0031] The bundling tool 343 is a member for bundling the end portion of the brush 341, and is fixed to the upper surface portion of the fixing plate 342.

[0032] Next, a method of using the coating container 1 described above will be described. FIG. 4 is a front partial cross-sectional view showing a state in which the volume change portion 32 of the coating container 1 in FIG. 1 is pressed down.

[0033] As shown in FIG. 4, when using the coating container 1, first, with the coating tool-attached cap 3 attached to the container 2, the volume change portion 32 is pressed by the user and elastically deformed and crushed. As a result, air is discharged from inside the shaft portion 33 into the container 2.

[0034] Next, the pressing of the volume change portion 32 is released. FIG. 5 is a front partial cross-sectional view showing a state in which the pressing of the volume change portion 32 of the coating container 1 in FIG. 4 is released. As shown in FIG. 5, when the pressing of the volume change portion 32 is released and the shape is restored from the state shown in FIG. 4 to the state shown in FIG. 5, the content liquid C in the container 2 is sucked into the shaft portion 33 at this time. The suction of the content liquid C is performed in an amount such that the liquid level of the content liquid C is positioned below the air hole 332d.

[0035] Next, the cap 3 with the applicator that has sucked in the content liquid C is removed from the container 2. FIG. 6 is a partial cross-sectional front view showing a state in which the cap 3 with the applicator is removed from the application container 1 in the state of FIG. 5. When the cap 3 with the applicator that has sucked in the content liquid C is removed from the container 2, the air holes 332d formed in the shaft portion 33 are released. As a result, even if the volume change portion 32 of the cap 3 with the applicator is pressed, the air pushed out from the volume change portion 32 is discharged to the outside through the air holes 332d, and it is possible to prevent the content liquid C in the cap 3 with the applicator from being excessively pushed out.

[0036] The content liquid C in the shaft portion 33 of the cap 3 with the applicator is gradually discharged to the brush 341 through the through hole 342c of the fixing plate 342. At this time, the content liquid C smoothly flows to the brush 341 along the lower end side peripheral wall portion 332b of the small diameter portion 332 and is guided by it.

[0037] Next, the content liquid C is applied using the cap 3 with the applicator. FIG. 7 is a front view showing a state in which the cap 3 with the applicator removed in FIG. 5 is used to apply nail polish to the nail N of the user's finger F. As shown in FIG. 7, the user holds the cap 3 with the applicator (the hand holding it is not shown), and uses the brush 341 of the applicator 34 to apply the nail polish, which is the content liquid C, to the nail N of the finger F. At this time, since the notch 332c is provided in the lower end side peripheral wall portion 332b, the brush 341 can be elastically deformed from this notch 332c and protrude outward from the shaft portion 33 to become larger, so that the operability of the cap 3 with the applicator can be improved, and the content liquid C attached to the brush 341 can be easily applied to the target location.

[0038] According to the application container 1 according to the above-described embodiment, a large amount of the content liquid C can be held in the cap 3 with the applicator by a single immersion in the content liquid C in the container 2, and the number of immersion operations during the application of the content liquid C can be reduced. Therefore, the application work to the target location can be easily performed, and the time required for the application work can be shortened.

[0039] Note that the present invention is not limited to the aspects according to the above-described embodiments, and various modifications can be adopted.

[0040] For example, in the above-described embodiment, the volume change portion 32 is an elastically deformable dome portion formed by three stages of an upper stage portion 321a, a middle stage portion 321b, and a lower stage portion 321c. However, in the present invention, it is only necessary that the volume can be changed. For example, as the volume change portion 32, a bellows portion in which mountain-shaped portions and valley-shaped portions are alternately provided in the vertical direction can also be adopted.

[0041] Further, in the above-described embodiment, the applicator 34 is provided with a brush 341. However, in the present invention, it is only necessary that the content liquid C can be applied, and an aspect having a sponge portion having a pen-like shape may also be used.

[0042] Further, in the above-described embodiment, the content liquid C is a nail polish. However, the present invention is not limited to this, and the content liquid C may be cosmetics such as lip gloss, mascara, and eyeliner, adhesives, lacquers, correction fluids, or the like.
