Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a cosmetic liquid application container for applying, for example, nail polish liquid.

``Prior art'' A brush is hung down inside the container from the back of the top wall of a cap screwed onto the mouth and neck of the container, and the liquid contained in the brush is applied by removing the cap and using the peripheral wall of the cap as a handle. It is known that such a device is installed.

``Problems to be Solved by the Invention'' There was a drawback that attaching and detaching the cap required time and effort.

The present invention is provided so that liquid within the barrel can be forcibly supplied to the brush tip at the lower end of the barrel by operating a button.

"Means for solving the problem" It has a storage cylinder part 2 formed with the same inner diameter on the upper and lower sides,
A cylindrical portion lower than the cylindrical portion is a cylinder 3 having a smaller inner diameter than the storage cylindrical portion, and a gap 6 is provided between the cylindrical portion and the inward flange 5 provided at the lower end of the cylinder. A shaft tube 1 in which a brush tip 9 is vertically disposed by fixing the base end 7, and the storage tube section 2.
A small diameter cylinder part 16 with a through hole 15 is suspended from a large diameter cylinder part 14 that is slidably fitted inward, and a cylindrical piston 17 attached to the lower end of the small diameter cylinder is located above the upper end of the cylinder 3. The sliding member 12 is biased upward so that the upper part of the valve rod 22 is erected by being loosely inserted into the flange hole serving as a valve hole from the valve body 21 which is pressed against the lower surface of the flange to form the discharge valve 20. The valve member 19 is fitted into the small diameter cylinder part 16 in a pinched state so that it can be forcibly slid into the small diameter cylinder part 16, and the large diameter cylinder is slidably inserted through the long hole 11 vertically provided in the storage cylinder part 2. An operation button 23 having a pin 24 protruding outward from the portion 14 and a finger rest portion 25 attached to the tip of the pin.
and a closing member 26 that is slidably fitted into the storage cylinder part 2 with its outer peripheral surface in watertight contact with the upper inner wall surface of the storage cylinder part, and extends from the lower end of the inward flange 5 to the cylinder length. A valve plate blocking member 10 is provided at a lower position shorter than that of the valve plate to make the stroke of the valve member 19 smaller than that of the sliding member 12, and when the sliding member 12 is pressed down via the operation button 23, the cylindrical piston 17 was provided to fit into the cylinder 3, and the long hole 11 was formed so as to be always closed by a sliding member 12.

"Operation" The operation button 23 is pressed against the shaft cylinder 1 from the state shown in the figure.
When pressed down, the sliding member 12 and the valve member 19 descend, and the discharge valve 20 opens. Next, the valve body 21 comes into contact with the valve plate blocking part 10 and the valve member stops descending, but the sliding member 12 further descends with respect to the valve member, and the cylindrical piston 17 descends inside the cylinder 3. The liquid passes through the valve hole and the gap 6 to the brush tip 9.
absorbed into. Next, when the operation button 23 is released, the small diameter cylindrical portion 16 is moved to the valve stem 2 by the bias of the spring 18.
The valve plate 21 comes into contact with the lower surface of the inward flange 5 and continues to rise even after the valve member 19 stops, causing the cylindrical piston 17 to come off from the cylinder 3, and the inside of the cylinder becomes negative. Since the liquid is pressurized, the liquid in the storage cylinder 2 flows in, and when the upper limit is reached, the sliding member 12 stops. In this way, the closing member 26 is lowered due to the negative pressure caused by the decrease of the liquid in the storage cylinder.

Embodiment The shaft cylinder 1 has a cylinder 3 below the storage cylinder part 2 and a lower cylinder part 4 below the cylinder, and the storage cylinder part 2 is formed to have the same inner diameter on the upper and lower sides. The cylinder 3 has an inner diameter smaller than that of the storage cylinder, and an inward flange 5 whose lower surface serves as a valve seat is attached to the lower end of the cylinder. Also, there is a gap between the flange and the flange.
6, a brush tip 9 is hung vertically at the lower end of the lower cylinder portion with the base end 7 of the brush tip fixed via a clamping tube 8, and above the base end there is a space between the bottom surface of the flange and the bottom surface of the flange.
A valve plate blocking portion 10 is provided at the end. The length between the blocking part and the flange 5 is shorter than the length of the cylinder 3. A long hole 11 is vertically provided in the storage cylinder part.

A sliding member 12 is slidably fitted into the housing cylinder portion 2. The sliding member 12 starts from a large-diameter cylindrical portion 14 with skirt-like portions 13, 13 at both upper and lower ends.
A small diameter cylinder part 16 with a through hole 15 is suspended, and a cylindrical piston 17 is attached to the lower end of the small diameter cylinder.
The cylindrical piston 17 has an outer diameter that is approximately the same as the inner diameter of the cylinder 3, and is positioned above the upper end of the cylinder.
It is urged upward by a spring 18.

In the valve member 19, a valve rod 22 is erected by being loosely inserted into a flange hole serving as a valve hole from a valve body 21 which is pressed against the lower surface of the inward flange 5 to form a discharge valve 20, and the valve rod 22 is erected by being loosely inserted into a flange hole serving as a valve hole. It is fitted in a pinched state so that it can be forcibly slid into the small diameter cylindrical part. Engaging protrusions may be provided on the outer periphery of the upper end of the valve stem and the inner periphery of the lower end of the small diameter cylindrical portion 16, respectively.

The operation button 23 has a pin 24 that is passed through the long hole 11 from the large-diameter cylindrical portion 14 and projects outward, and a finger rest 25 is attached to the tip of the pin. The sliding member 12 can be moved up and down via the finger rest.

The closing member 26 is attached to the upper inner wall surface of the storage cylinder section 2.
It is slidably fitted into the housing cylinder part with its outer peripheral surface in watertight contact with the housing cylinder part 2, and is provided so as to descend when the internal pressure of the housing cylinder part 2 becomes negative to eliminate the negative pressure state. It is preferable that the center part of the horizontal wall 27 of the member is suspended in a cylindrical shape with the lower end closed, so that the cylindrical part 28 is fitted into the large diameter cylindrical part 14 of the sliding member 12 when descending. A plug 30 with a through hole 29 is fitted into the upper end of the storage cylinder 2.

"Effect of the invention" Since the present invention has the above-described configuration, the liquid in the housing cylinder can be forcibly absorbed into the brush tip by moving the operation button 23 up and down, thereby making it possible to forcibly absorb the liquid into the brush tip. This can be easily done, and the valve plate blocking portion 10 is provided at a lower position shorter than the length of the cylinder from the lower end of the inward flange 5 to make the stroke of the valve member 19 smaller than that of the sliding member 12. Since the upper part is fitted into the small diameter cylindrical part 16 in a pinched state so that it can forcibly slide, and since the cylindrical piston 17 at the lower end of the small diameter cylindrical part 16 is positioned above the upper end of the cylinder 3, it is further possible to fit inside the storage cylindrical part. Since the negative pressure caused by the decrease in liquid is resolved by lowering the closing member 26, when the sliding member is moved upward from the lower limit position by force, first the discharge valve 20 is closed, and then the cylindrical The piston 17 rises inside the cylinder 3 to create a negative pressure inside the cylinder, and then the cylindrical piston 17 comes off from the cylinder 3, and the liquid inside the storage cylinder 2 is released to eliminate the negative pressure inside the cylinder. Since the liquid is sucked into the cylinder, the cylinder 3 and the cylindrical piston 17 also serve as a suction valve, and the pump mechanism for forced liquid outflow can be simplified.
