DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The decorative brush 1 of the present invention includes a container body A, a support body B, a movable brush C, and a cap D.
[0006]
The container body A is configured by raising the mouth-and-neck part 3 from the upper end edge of the vertically long cylindrical body part 2. The body portion 2 of the container body A can be configured to be squeezable, and may be configured to be rigid and difficult to squeeze and be appropriately selected depending on the type and nature of the stored liquid. good.
[0007]
The support B has a flange 5 extending inwardly from a lower part of the inner peripheral surface of the peripheral wall 4 in which the inner peripheral lower part is tightly fitted to the outer periphery of the container neck part 3, and the guide cylinder 6 is extended upward from the inner peripheral edge of the flange 5. It is configured to stand up. In the present embodiment, the upper end portion of the guide tube 6 is bent inwardly, and a thread for screwing the cap D around is provided on the outer periphery of the peripheral wall 4.
[0008]
The movable brush C is provided with a plurality of support columns 8 extending from the lower part of the outer surface of the support tube 7 fitted in the guide tube 6 so as to be slidable in the vertical direction, and extending in the circumferential direction. A ring-plate-shaped inner lid 9 is fixed to the upper surface of each column 8 that penetrates the flange 5 in a liquid-tight manner and protrudes upward, and the application portion 10 having a base end fixed to the upper end of the support tube 7 is guided to the guide tube 6. It is provided so that it can be stowed inside and moved up and down in an upward biased state.
[0009]
In this embodiment, the support cylinder 7 has a cylindrical shape in which the outer surface of the upper end, which is almost perfectly accommodated in the guide cylinder 6, is curved and reduced in diameter, and the locking protrusion 11 for supporting the application part 10 is provided on the upper surface of the inner surface. Is protruding. Further, each support column 8 is configured to stand upward from the outer peripheral edge portion of the outward flange 12 extending outward from the lower end edge of the support cylinder 7, and is provided with four front, rear, left and right. Further, a sealing material 13 made of an elastomer or the like is closely fitted on the upper surface of the flange 5 of the support B, and each of the sealing materials 13 is inserted through a through hole 14 formed at a predetermined position. By projecting the support column 8 upward, the liquid-tightness of this portion is achieved.
[0010]
The inner lid 9 serves as a pressing surface when the movable brush C is pressed down by the cap D, and a contact portion of the lower surface is fixed to the upper surface of each column 8 by an appropriate fixing means such as adhesion or fusion. In the present embodiment, it is configured in a ring shape in plan view that curves downward as it goes outward, and the inner periphery is fitted to the outer surface of the guide tube 6 and the outer periphery is fitted to the inner surface of the support peripheral wall 4 so as to be movable up and down. It is combined.
[0011]
The applicator 10 can be used as long as it is used as an applicator for a conventional brush of this type, such as a bundle of fibers or an integral part of a porous material. In the present embodiment, a bundle of fibers is used, the lower end is fixed to the upper end in the support cylinder 7 above the locking protrusion 11 and the application part 10 is raised upward. In a pushed down state, it is raised to a length that can be stored in the guide tube 6.
Further, as means for constantly urging the movable brush C upward, a coil spring 15 is interposed between the rear surface of the inner lid 9 and the upper surface of the sealing material 13.
[0012]
The cap D is detachably mounted by fitting the inner peripheral lower portion of the peripheral wall 16 to the outer periphery of the support peripheral wall 4, and the movable brush C is pressed by pressing the upper surface of the inner lid 9 by a pressing cylinder 18 suspended from the back surface of the top wall 17. Is pushed down and locked.
[0013]
In this embodiment, the inner peripheral lower portion of the peripheral wall 16 is screwed to the outer periphery of the support peripheral wall 4 so as to be prevented from being pulled upward. You may comprise so that it may prevent.
In the present invention, in a state where the movable brush C is pushed down and locked, the stopper 19 suspended from the back surface of the cap top wall 17 is tightly fitted to the upper opening of the guide tube 6 so that the sealed chamber X is formed around the application portion 10. It is composed.
[0014]
By forming the sealed chamber X, the periphery of the coating unit 10 is sealed in a relatively small space when the cap D is not used, and the coating unit 10 is prevented from drying. Even if there is leakage, it is configured to prevent leakage to the outside.
[0015]
When the makeup brush 1 configured as described above is used, first, the makeup brush 1 is erected, the cap D is removed, the movable brush C is raised by the upward biasing force of the coil spring 15, and the application portion 10 thereof is applied. Is projected from the upper end opening of the guide tube 6 and used.
Further, after use, the cap D is mounted while the movable brush C is pushed down by the pressing cylinder 18. At this time, a sealed chamber X is formed around the application unit 10 to prevent the application unit 10 from drying. However, a storage liquid having a low viscosity is selected, or an application unit having good liquid permeability is selected. Thus, when the makeup brush 1 is laid down or stored with the application unit 10 facing down, the liquid passes from the inside of the container through the support cylinder 7 and into the sealed chamber X through the application unit 10. In this case, the application unit 10 is always in contact with the liquid, and drying can be prevented more reliably. The liquid transferred to the sealed chamber X is small in volume because the sealed chamber X can be configured in a relatively small space due to its structure, and returns to the application unit 10 when it is erected to remove the cap. Since the inside of the support cylinder 7 is slightly negative pressure when it is raised, there is very little possibility of returning to the inside of the application part 10 and dripping in use.
Each of the above members is preferably formed of a synthetic resin or the like.
[0016]
【The invention's effect】
As described above, the decorative brush of the present invention has the above-described configuration. In particular, the stopper 19 suspended from the back surface of the cap top wall 17 is closely fitted to the upper opening of the guide tube 6 in the state where the movable brush C is pressed and locked. Since the sealed chamber X is formed around the coating unit 10, only a small amount of air is present in the small sealed chamber X around the coating unit 10, so that drying of the coating unit can be prevented as much as possible. Also, when the makeup brush is laid down or stood with the application part down, even if there is a liquid transfer in the sealed chamber through the application part 10, it does not leak to the outside. It is more reliably prevented that the liquid always exists around the application part and the application part dries.
[0017]
In addition, since the sealed chamber X can be formed in a relatively small space due to its structure, even if the liquid moves around the coating part, a small amount is returned to the coating part when it is erected to remove the cap, and is movable. Even if the inside of the support cylinder is slightly negative pressure when the brush is lifted, it returns to the inside of the application part, and as a result, there is very little risk of liquid dripping when used with the cap removed, and good storage liquid application Can be done.
[0018]
Further, the movable brush C automatically protrudes when the cap is removed, and the movable brush can be automatically pushed in and stored when the cap is attached, which is very convenient in use.
