Abstract

PROBLEM TO BE SOLVED: To reduce the number of times of a supply operation to a brush tip by forming a recessed part on the inner surface of a fixing tube side bisected in a vertical direction for which an end part is bendably connected to a base part and turning the recessed part to a liquid accumulation part. SOLUTION: When the knocking part of a container 1 is pressurized, an accordion part is contracted, the inside of the container 1 is pressurized and the inner surface of the knocking part is soon abutted to the peak part of a valve rod. Further, when a pressurizing operation is continued, a first valve member is separated from the front end part of a valve seat part, a valve hole is formed and liquid inside the pressurized container 1 is made to flow out and supplied to an application tip 9 through a porous body 10 and a pipe 12. At the time, the liquid is made to flow out of the side face of the application tip 9 and supplied also to the recessed part 14 of a tip holder 11. When it is pressurized further, a second valve part is abutted to the rear end part of the valve seat part to close the valve hole and the flow-out and supply of the liquid inside the pressurized container 1 to the porous body 10 or the like are interrupted. Since the valve is opened and the liquid inside the container is pressurized by performing the pressurizing operation, even the liquid of a relatively high viscosity is easily elected.

FIG. 1 shows an example of a makeup tool. Specifically, it is a nail color having a brush ear having a circular cross section at the tip. Reference numeral 1 denotes a container having a bellows portion 1a having self-elasticity obtained by blow molding of polyethylene, polypropylene, nylon, ethylene-vinyl alcohol copolymer or the like at the rear portion. A holder 2 for press-fitting and fixing a later-described brush ear fixing tube is attached to a front end opening of the container 1, and the holder 2 may be integrated with the container 1. Inside the holder 2,
A valve seat 2a is formed. And this valve seat part 2a
The valve rod 3 is constantly urged rearward with respect to the (holder 2) by an elastic member 4 such as a coil spring stretched between the rear end of the valve seat 2a (holder 2). However, the repelling member 4 may be arranged in front of the valve rod 3,
Further, it may be appropriately integrated with the valve rod 3 or the valve seat 2a (holder 2). The valve rod 3 extends inside the container 1, and forms a small space 5 at the rear end with the inner wall of the rear end of the container 1. The rear end of the container 1 is a knocking portion 6.

The valve rod 3 is composed of a first valve rod 7 and a second valve rod 7.
And a first valve rod 7a for contacting the front end face of the valve seat 2a at the tip of the first valve rod 7 to close the valve hole 2b. Are formed. On the other hand, the tip of the second valve rod 8 contacts the rear end face of the valve seat 2a to close the valve hole 2b.
a is formed. In this embodiment, the second valve portion 8a is formed by making the diameter of the second valve rod 8 larger than the diameter of the first valve rod 7. And the second valve rod 8 may be integrally formed, and the first valve portion and the second valve portion may be formed as large diameter portions.

At the tip of the container 1, a round or flat brush-like application point (brush) 9 formed by converging crimp-shaped or linear fibers is projected. A tip holder (fixed tube) 11 having a porous body 10 serving as a temporary liquid reservoir at the rear end of the coating destination 9 is press-fitted, screwed,
It is attached by appropriate means such as adhesion. Further, the application destination 9 and the porous body 10 are communicated with each other by a pipe 12, so that the flowability of the liquid to the application destination 9 is improved. Reference numeral 13 denotes an air exchange slit. Air passes through the air exchange slit 13 by selecting a relatively large and weak capillary force in the space of the porous body 10 and passing through the inside of the container 1. Invade. A plurality of vertically long concave portions 14 for storing the liquid from the pipe 12 are formed radially on the inner surface of the tip holder 11.

As shown in FIGS. 5 and 6, the chip holder 11 is composed of chip holder sides 15 and 16 obtained by dividing the chip holder 11 into two parts in the vertical direction. One end of 16 is connected to bendable via a circular base 17. Also,
At the center of the base 17, a tubular pipe 12 inserted into the application destination 9 is integrally formed upright. A plurality of vertically long concave portions 14 for storing the above-mentioned liquid are radially formed on the inner side surfaces of the respective chip holder sides 15, 16.
A groove 18 is formed in which a is locked and fixed. still,
The diameter of the inscribed circle in contact with the top of the recess 14 is the same as the outer diameter of the brush 9 and the outer periphery of the tip 9 is partially held by the top 14a of the recess 14. Further, a slit 19 for air exchange is formed at a position facing the side surface of the base portion 17. The tip holder side 1
When the tip holders 5 and 16 are bent to form the chip holder 11, as shown in FIG. 6, the air exchange slit 13 is formed on the joint surface. The front inner surface of the tip holder 11 has a play insertion hole 11a that does not contact the outer diameter (surface) of the application destination 9, thereby improving the air flow in the air exchange.

Reference numeral 20 is a ball for stirring the cosmetic liquid in the container 1, but depending on the liquid used,
It is not necessary. Reference numeral 21 is a cap for preventing the application destination 9 from drying, and is detachably attached by appropriate means such as concave and convex fitting or screwing. In the present embodiment, the double caps (the outer cap 22 and the inner cap 23) are used, and the air circulation holes 24 are formed at the connection portions. In the unlikely event that a child
This ensures air circulation when the cap is swallowed. Further, in the present embodiment, the container 1 itself is used as the liquid storage portion. However, an exterior body may be provided outside the container 1 to improve the rigidity of the product.

Next, a method of fixing the application destination 9 to the chip holder 11 will be described. First, as shown in FIG.
Is spread, and the application destination 9 is inserted into the pipe 12. Next, the chip holder sides 15 and 16 are closed, and in this state, the chip holder 11 is pressed into the holder 2. At this time, the bristles located on the surface of the application destination 9 are not affected by the action in the vertical direction, and thus are caught and do not come loose, and the chip holder side 1 is not broken.
It is pinched by 5 and 16. However, the present invention is a particularly effective means for a round brush or a flat brush having a uniform fiber thickness.

Next, the operation will be described. When the knock portion 6 of the container 1 is pressed, the bellows portion 1a is contracted and the inside of the container 1 is pressurized, and the inner surface of the knock portion 6 comes into contact with the top of the valve rod 3 soon. Here, when the pressing operation is further continued, the first valve member 7a is separated from the front end face of the valve seat 2a, and the valve hole 2b is formed. Then, the liquid in the pressurized container 1 flows out and is supplied to the application destination 9 via the porous body 10 and the pipe 12. At this time, the liquid flows out from the side surface of the application destination 9 and the concave portion 1 of the tip holder 11.
4 as well. In this state, if you press further,
The valve portion 8a contacts the rear end face of the valve seat portion 2a and the valve hole 2b
Is closed. Thus, the flow of the liquid in the pressurized container 1 to the porous body 10 and the like is cut off.
In this example, the valve is opened by performing the pressing operation, and the liquid in the container is pressurized, so that the liquid having a relatively high viscosity can be easily discharged. .

A modified example will be described with reference to FIGS. This is an example in which the pipe 12 of the previous example is extended forward so that the liquid can be supplied as soon as possible to the tip of the application destination 9 when the pipe 12 is used for the first time. Explaining below, the pipe 25 for guiding the liquid from inside the container 1 to the tip member 9 is formed so as to extend to substantially the center of the tip member 9 with its front end protruding from the front end of the tip holder 11. A plurality of through-holes 26 are formed in the side surface of the pipe 25 to allow the liquid to penetrate into the intermediate portion of the application destination 9 and the tip holder-1.
The liquid supply to the first recess 14 is improved. Also,
By forming the pipe 25 so as to extend substantially to the center of the application destination 9, bending at the central portion due to application of the application destination 9 is also prevented.
