Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a liquid container with an applicator for storing a liquid cosmetic and having a cosmetic applicator for eye shadow and eyebrow application.

``Prior art'' Conventionally, this type of applicator is used by inserting a separate applicator into a liquid pot each time you apply makeup, or by using a pencil-shaped container with an applicator attached to one end. There are devices that supply cosmetic liquid all the time or when needed.

``The problem that the invention attempts to solve'' In the conventional method, the former is time-consuming to use;
It is inconvenient to carry, and in both methods, the makeup brush is attached directly to the liquid part.
Difficult to prevent dripping.

The present invention includes a cylinder closed with a valve,
To provide a liquid container with an applicator that is configured to supply a constant and appropriate amount of cosmetic liquid at the required time from this cylinder by push-button operation, is extremely easy to handle, does not drip, and is convenient to carry.

"Means for Solving Problems" The liquid container with an applicator of the present invention has a straight cylindrical body 7, and a bottom lid 8 that can be lifted up is liquid-tightly provided at the bottom of the body 7. 1, a cylinder 2 whose lower half is fitted inside the mouth and neck part 9 of this container body 1 and protrudes upward, and has a suction valve 10 installed in its lower part; A spatula-shaped applicator comprising a cylindrical applicator shaft 3 extending upward and a sponge-like applicator body 12 attached to a substrate 11, and fixed or replaceably attached to the upper end opening of the applicator shaft 3. The tool 4 has an upper end fixed to the upper inner surface of the applicator shaft 3, a lower end formed into a cylindrical piston 13 inscribed in the cylinder 2, and an upwardly stepped valve seat 14 formed on the inner peripheral surface of the intermediate portion. A cylindrical member with a piston 5 is urged in a direction away from the cylinder 2 by a return spring 15, and an elastic compression plate part 16 whose upper end cylinder part is fixed to the applicator shaft 3 or the inner surface of the member with a piston 5. hangs down and presses against the valve seat 14 below the plate portion 16 to form the discharge valve 17.
A member 6 with a valve body is provided with a valve body 18 that forms a valve body 18.

"Function" In the above, the applicator shaft 3, the member with the piston 5, and the member with the valve body 6 are normally pushed up to the upper limit by the return spring 15, and the cosmetic liquid sucked into the cylinder 2 by the suction valve 10 is It's full.

Here, when applying makeup, the cap 19 is removed and the combined body of the container body 1 and the cylinder 2 is pushed up against the return spring 15 (or the applicator shaft 3, the member with the piston 5, and the member with the valve body 6 are pushed down). Then, since the cosmetic liquid in the cylinder 2 is pressurized, this pressurized cosmetic liquid is applied to the elastic compression plate portion 1 of the member with a valve body 6.
6 pushes the lower part of the plate part 16 upward and opens the discharge valve 17, so that the cosmetic liquid is supplied to the applicator 4 through the compression plate part 16. This supply creates a negative pressure inside the cylinder 2, so the suction valve 10 opens, the cosmetic liquid inside the container body 1 is sucked into the cylinder 2, and the bottom cover 8 moves upward accordingly.

Embodiment First Embodiment (FIGS. 1 and 2 a and b) A push button 20 for push-in operation is fixed to the lower end opening of the container body 1 so as to protrude downward. This push button 20 has an upright shaft 21 in the center and a breather hole 22 in a part. The bottom cover 8 has a circumferential edge formed into an elastic peripheral wall 23 having an arc-shaped cross section, and this elastic peripheral wall 23 is brought into pressure contact with the inner surface of the body part 7, so that the bottom cover 8 is internally installed in a liquid-tight manner and capable of rising.

The cylinder 2 has an outward flange 24 on the outer surface of the intermediate portion locked to the top surface of the mouth of the container body, and a lower half portion fitted and fixed to the neck portion 9 by the rough surface, and a return spring 15 on the inner periphery of the upper end. Upward step 2 as a support part
5 is formed. The suction valve 10 has a check valve function, and although a ball valve is shown in the figure, it may also be an elastic plate-shaped valve in which a tongue-shaped valve portion is cut into an elastic plate.

The applicator shaft 3 has a tapered upper part, and a spiral cylinder 26 whose diameter is slightly reduced in a step-like manner and has a spiral groove formed on the inner surface is integrally hung from the inner surface of the upper part.

The base plate 11 of the applicator 4 is attached to the upper half of the cylinder shaft 27.
It has a spatula-shaped shape resembling a military fan, with a plate body 28 vertically straddled so that both sides of the upper end opening of the cylinder shaft communicate with the outside.
The lower part of the coating body 12 is tied and fixed with a string 29, and the thread 30 on the outer surface of the lower part of the barrel shaft 27 is screwed into the threaded barrel 26. It is installed so that it can be replaced.
In the sectional view of FIG. 1, the applicator 4 is shown divided into a left half section taken along the line AA in FIG. 2 and a right half section taken along the line BB.

The piston-equipped member 5 is fitted and fixed to the applicator shaft 3 with an appropriate gap between it and the lower end of the applicator 4 through an outward flange 31 at its upper end, and its lower half is inwardly reduced in diameter in a stepped manner. The cylindrical piston 13 at the lower end has elasticity and comes into fluid-tight pressure contact with the inner surface of the cylinder 2, and the outward flange 31 and the upward stage at the upper end of the cylinder 2 are connected to each other. It is constantly pushed upward by a return spring 15 disposed between the parts 25.

The member with a valve body 6 is mounted and fixed by sandwiching an outward flange 33 protruding from an upper end cylindrical portion 32 communicating with the cylindrical shaft 27 of the applicator 4 between the lower end of the applicator 4 and the upper end of the member with a piston 5. Yes, upper end cylinder part 3
A shaft 34 is provided which hangs down from the cylinder 2 axis core part through elastic compression plates 16, 16 on both sides curved from 2, and an outwardly flange-shaped valve body 18 is pressed from above to the valve seat 14 from above the shaft 34. has been established. The shaft 34 adjusts the internal volume of the cylinder 2, and during the return operation, its lower end serves to push down the suction valve 10 and forcibly return it.
