"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; It has a cylindrical cosmetic shaft 3 which extends upwardly and has a screw tube 12 fixed therein in a non-rotatable manner by a rotation stopper rib 11 at the upper end opening, and a cylindrical shaft 13 for attachment. a cosmetic tool 4 that is replaceably attached to the upper end opening of the cosmetic tool shaft 3 via the screw tube 12; and a cylindrical piston whose upper end is fixed to the upper inner surface of the cosmetic tool shaft 3 and whose lower end is inscribed in the cylinder 2. 14, an upwardly stepped valve seat 15 is formed on the inner circumferential surface of the intermediate portion, and a cylindrical piston-equipped member 5 is biased in a direction away from the cylinder 2 by a return spring 16; is fixed to the inner surface of the cosmetic shaft 3 or the member with piston 5, and an elastic compression plate part 17 is suspended, and a valve body 19 is provided below the plate part 17 to press against the valve seat 15 to form a discharge valve 18. It is composed of a member 6 with a valve body.

"Operation" In the above, the cosmetic 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 16, and the cosmetic liquid sucked into the cylinder 2 by the suction valve 10 is It's full.

Here, when applying makeup, the cap 20 is removed and the combined body of the container body 1 and the cylinder 2 is pushed up against the return spring 16 (or the cosmetic tool 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.
7 pushes the lower part of the plate part 17 upward and opens the discharge valve 18, so that the cosmetic liquid is supplied to the cosmetic tool 4 through the compression plate part 17. 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.

"Example" First Example (Fig. 1, Fig. 2 a, b, Fig. 3) A push button 21 for push-in operation is fixed to the lower end opening of the container body 1 so as to protrude downward. . This push button 21 has an upright shaft 22 in the center, and a breather hole 23 in a part thereof. The bottom cover 8 has a circumferential edge formed into an elastic peripheral wall 24 having an arcuate cross-section, and this elastic peripheral wall 24 is brought into pressure contact with the inner surface of the body 7, so that the bottom lid 8 is installed in a liquid-tight manner and capable of rising.

The cylinder 2 has an outward flange 25 on the outer surface of the intermediate portion that is engaged with the top surface of the mouth of the container body, and a lower half portion that is internally fixed to the mouth and neck portion 9 by means of a rough surface, and a return spring 16 on the inner periphery of the upper end. Upward step 2 as a support part
6 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 cosmetic tool shaft 3 has an upper part tapering upward, and a screw cylinder 12 having a spiral groove formed on the inner periphery is fixedly fitted into the inner surface of the upper part by ribs 11 so as to be non-rotatable. That is, the upper end portion of the cosmetic tool shaft 3 is thickened inward to form a downward step portion 27 on the upper inner surface, and this downward step portion 2
A large number of engagement grooves 11a are provided on the enlarged diameter inner circumferential surface immediately below 7, and a large number of engagement protrusions 1 that engage with the engagement grooves 11a are provided on the outer circumferential surface of the outward flange at the lower end of the screw tube 12.
1b, and their engagement makes it impossible to rotate.

The cosmetic tool 4 is an example of a sponge-like application body, and resembles a military fan, with a plate 28 vertically straddled over the upper half of the cylinder shaft 13 so that both sides of the upper end opening of the cylinder shaft 13 communicate with the outside. A bag-shaped coating sponge 29 is placed over the outer surface of the spatula-shaped substrate, so that a relatively wide coating surface can be obtained. This sponge 29
The lower part is tied and fixed with a string 30, and the thread 31 on the outer surface of the lower part of the cylinder shaft 13 is screwed into the threaded cylinder 12, so that it can be replaced. In addition, in the cross-sectional view of Fig. 1,
The cosmetic tool 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 cosmetic tool shaft 3 with an appropriate gap between it and the lower end of the cosmetic tool 4 through an outward flange 32 at the upper end, and its lower half is inwardly reduced in diameter in a stepped manner. The cylindrical piston 14 at the lower end has elasticity and comes into liquid-tight pressure contact with the inner surface of the cylinder 2, and the outward flange 32 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 16 disposed between the parts 26.

The member with a valve body 6 is mounted and fixed by sandwiching an outward flange 34 protruding from an upper end cylindrical portion 33 communicating with the cylindrical shaft 13 of the cosmetic tool 4 between the lower end of the cosmetic tool 4 and the upper end of the member with a piston 5. Yes, upper end cylinder part 3
A shaft 35 is provided which hangs down the two-axis core portion of the cylinder through elastic compression plates 17, 17 on both sides curved from the shaft 35, and an outwardly flange-shaped valve body 19 is pressed from above to the valve seat 15 from above the shaft 35. has been established. The shaft 35 adjusts the internal volume of the cylinder 2, and at the time of return operation, its lower end serves to push down the suction valve 10 and forcibly return it.

The cap 20 is fitted onto the outer surface of the cosmetic tool shaft 3.

Reference numeral 36 denotes an external cylinder whose upper part is fitted onto the outer surface of the lower part of the applicator shaft 3, and an inward flange 3 that locks the outward flange 25 of the cylinder 2 on the inner circumferential surface near the upper part.

Second Embodiment (FIGS. 4a and 4b, FIGS. 5 and 6) In this embodiment, a flat brush is used as the cosmetic tool 4. This flat brush has an outward flange 39 at the top end.
The lower half of the cylinder core 40 is inserted into the cylinder shaft 13 provided with the cylinder core 40, and a round brush tip 41 is provided on the upper surface of the cylinder shaft 13 so that the cylinder core 40 serves as a core. A jacket tube 42 made of a metal material is placed over the outer surface of the flange 39, the lower end of the jacket tube 42 is caulked to engage the lower surface of the flange 39, and the upper half is crushed to form a flat brush. This flat brush can be used for both wide and narrow makeup.

In both of the embodiments described above, the cylinder 2 is set to have a volume that accommodates an appropriate amount of liquid that is sufficient but not excessive for the cosmetic tool 4. In addition, each part has a return spring 1
6. It is molded and manufactured from synthetic resin material except for the outer jacket cylinder 42.

"Effect of the invention" In the above invention, a cylinder 2 is provided separately in addition to the container body 1, and the cosmetic liquid is supplied from the cylinder 2 to the cosmetic tool 4 when necessary. Since the container body 1 and the cosmetic tool 4 are always tightly disconnected by the discharge valve 18, there is no fear of liquid dripping to the outside. Further, since the overall shape is a pencil shape, it is suitable for portable use, and the operation is a one-touch operation of pressing the bottom of the container body 1 via the push button 21, which is simple and hassle-free. Further, since the cosmetic tool 4 can be easily replaced, only one set of container bodies is required, which is economical and convenient for carrying.
