Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for use with a tip valve type valve applicator which contains a coating liquid such as a correction liquid, a cosmetic liquid, a pigment-based marking ink, or the like.

[0002]

2. Description of the Related Art Coating liquids such as correction liquids, cosmetic liquids, and pigment-based marking inks are difficult to restore once dried. Therefore, such a coating liquid is used by being incorporated in a valved applicator of the tip valve type in order to prevent the coating liquid from being dried. Various tip valve type applicators with a valve have been conventionally proposed. For example,
In JP 60470, a tip shaft is fixed to a mouth portion of a main body container, and a valve rod having a pressing core portion protruding from a tip discharge port of the tip shaft is pressed against a seat portion of the tip shaft by a spring. An applicator having the following valve mechanism is disclosed. In Japanese Utility Model Laid-Open No. 6-63173, a spherical applicator is rotatably held with a part thereof protruding from the tip of the chip, and the spherical applicator is repelled by a spring to provide the chip. Discloses an applicator having a valve mechanism formed in contact with the inward tip edge of the.

By the way, when the above-mentioned tip valve type valve-applied applicator is used for coating, the coating liquid adheres to the periphery of the tip end of the tip shaft or the tip of the tip. When this coating liquid dries, it becomes a solid substance mainly composed of pigments and resins, and the presence of this solid substance interferes with the coating at the time of the next use or adheres to the coating surface to finish the coating surface. Cause a problem of lowering. Therefore, it has been proposed to add a function of removing the solid matter to a removable cap of the valved applicator, which is used for the purpose of protecting the valve mechanism at the tip of the valved applicator. For example, Japanese Utility Model Laid-Open No. 63-7596 discloses a cap for an erasing pen, which is characterized in that a polyolefin-based open-cell resin is attached to the inside of the cap so as to be positioned at the pen tip when the pen shaft is inserted. The erase pen cap is described.

[0004]

The valve may open when the cap is attached to the applicator with a valve. In the tip valve type applicator with a valve, as described above, regardless of whether the valve element is rod-shaped or spherical, the application portion of the valve element projects from the application liquid discharge port at the tip of the application tool. Therefore, when the cap is attached to the valve-applied applicator, the coating portion of the valve body protruding from the coating liquid discharge port comes into contact with the open-cell resin.
At the beginning of use, since the hardness of the open-cell resin is low,
Even if the coating part of the valve body comes into contact with the open-cell resin, it is unlikely that the valve body will retreat and the valve will open against the force of the elastic body that urges the valve body, but for a long time. When used, the solid matter adhered to the tip of the applicator adheres to the surface of the open-cell resin to increase the hardness of the open-cell resin. As a result, there is a problem that the valve opens when the cab is attached, the coating liquid leaks, and the coating liquid dries and solidifies inside the tip of the coating tool.

[0005]

SUMMARY OF THE INVENTION The present invention is a cap that is attachable to and detachable from a valve-applied applicator of the tip valve type, wherein the tip of the valve-applied applicator when the valve-applied applicator is mounted inside the cap, The gist of the cap of the applicator with a valve is that an elastic continuous pore body having a through hole having a diameter slightly smaller than the tip of the applicator with a valve is formed in the axial direction.

[0006]

The cap of the valve-applied applicator according to the present invention has an elasticity in which a through hole having a slightly smaller diameter than the valve-applied applicator tip is formed in the axial direction at the valve-applied applicator tip position when the valve-applied applicator is attached. Since the continuous pore body is attached, when the applicator with a valve is attached to the cap, the coating liquid adhering to the tip of the applicator with a valve and the solid matter formed by drying the coating liquid are absorbed by the elastic continuous pore body. , It is peeled off and removed well. Moreover, when the applicator with valve is attached to the cap, the applicator with valve is
Since it is inserted into the through hole of the elastic continuous pore body, the application portion of the valve body does not receive the pressing force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. Example 1 FIG. 1 shows Example 1, and FIG. 2 is an enlarged view of a main part of FIG. Reference numeral 1 is a bottomed cylinder whose inside is a chamber for applying a correction liquid, a cosmetic liquid, a pigment-based marking ink, or the like. In the coating liquid storage chamber of the barrel 1,
A stirrer 2 that disperses the coloring material by stirring the coating liquid is arranged. A front shaft 3 having a through hole is fixed to the opening of the shaft cylinder 1 by an appropriate means such as screwing or bonding. Further, a pen tip portion 4 for ejecting the coating liquid is inserted and fixed to the tip of the front shaft 3. The pen tip portion 4 has a tubular tip body 5 in which a seat portion 5b is formed inside the rear end of the tip end hole 5a, and an application portion 6a protrudes from the tip end hole 5a, and the valve portion 6 is attached to the seat portion 5b.
It is formed by a valve body 6 which is urged by an elastic repellent body 7 so as to be pressed against b. The seat portion 5b and the valve portion 6b form a valve mechanism that closes the valve when pressed against each other, and opens when the valve body 6 retracts and the pressure contact is released.

Reference numeral 11 is a cap which can be attached to and detached from the front shaft 3. The cap 11 is an inner and outer double cylinder, and is an integrally molded product in which the inner cylinder 12 and the outer cylinder 13 are connected at the tip portion to form a bottom portion. Reference numeral 14 is an elastic continuous pore body. The elastic continuous pore body 14 has a through hole 1 having a diameter slightly smaller than the outer diameter of the tubular front body 5 which is the tip of the valved applicator.
4a is provided in the axial direction and is arranged in the inner cylinder 12 of the cap 11. When the applicator with a valve is attached to the cap, the tubular front body 5, which is the tip of the applicator with a valve, is inserted into the through hole 14 a of the elastic continuous porosity 14 when the applicator with a valve is mounted. It is necessary to be in a position where The insertion length of the tubular front body 5 into the through hole 14a is not particularly limited, but the longer the better in order to enhance the effect of removing the deposits on the tip of the valved applicator. As the elastic continuous pore body 14, foamed various resins such as polystyrene, polyurethane and polyethylene can be used, and the density thereof is preferably ^{30 to} 70 kg / m ³ . The through hole 14a of the elastic continuous pore body 14 is for preventing the coating portion 6a of the pen tip portion 4 from touching the elastic continuous pore body 14 when the applicator with valve is mounted on the cap 11. Therefore, a bottomed bag hole or a hole without a hole is not preferable.

In the first embodiment, in the applicator with valve,
