Description

The present invention relates to an applicator.

Patent Document 1 includes a pen tip, a coating liquid storage body to which the pen tip is connected, a cartridge that stores the coating liquid, and a coating liquid lead-out member that connects the inside of the cartridge and the coating liquid storage body. An applicator is disclosed.

Japanese Utility Model Publication No. 6-32220

In the applicator of the above-mentioned document 1, when the application liquid is supplied for the first time (when the application liquid is supplied to the application liquid storage body for the first time), the application liquid cannot be supplied quickly from the inside of the cartridge to the pen tip and can be applied. It takes a considerable amount of time.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an applicator that can be applied in a short time when the first application liquid is supplied.
In the present invention, “front” refers to the pen body side, and “rear” refers to the opposite side.

<1> The first invention of the present application is a pen body made of a porous material, a coating liquid storage body made of a porous material connected to the rear end of the pen body, and disposed behind the coating liquid storage body. An applicator comprising: a coating liquid tank that directly stores the coating liquid; and a communication pipe that connects the coating liquid tank and the coating liquid storage body. The applicator includes a plurality of the communication pipes, and the communication pipe It is a requirement that each front end of each of the communication pipes is opened and that each front end of the communication pipe is positioned inside the coating liquid storage body.

In the applicator of the first invention, each of the communication pipes has a function of supplying the application liquid in the application liquid tank to the inside of the application liquid storage body and a function of supplying outside air to the application liquid tank. Prepare. When supplying the coating liquid in the coating liquid tank to the coating liquid storage body, when the pen body is turned downward, the coating liquid in the coating liquid tank is pulled by gravity through the at least one communication pipe to the coating liquid storage body. It is supplied and impregnated inside the coating liquid storage body. At the same time, the outside air is taken into the coating solution tank through another communication pipe.

When the coating liquid impregnated inside the coating liquid storage body reaches a certain amount, the front end opening of the other communication pipe that has taken in the outside air is in a liquid-sealed state with the impregnating coating liquid, and is temporarily closed, The supply of outside air into the coating liquid tank is stopped. At the same time, the supply of the application liquid from the application liquid tank to the application liquid occlusion body by the communication pipe that has been supplying the application liquid is also stopped, and as a result, each front end opening of the communication pipe is temporarily in a liquid seal state. Thus, the outflow of the coating liquid from the coating liquid tank and the inflow of air into the coating liquid tank (that is, replacement of the coating liquid and air) are stopped.

In the applicator of the first invention, the front end of each of the communication pipes is positioned inside the coating liquid storage body, so that all of the front end openings of the communication pipes are placed inside the coating liquid storage body. It can be easily closed by a liquid seal of the impregnated coating solution. As a result, an excessive coating liquid is not supplied from the coating liquid tank to the coating liquid storage body, and there is no possibility that the coating liquid leaks outside from the pen body side.

In addition, the applicator of the first invention has a plurality of communication pipes (that is, two or more), so that when at least one communication pipe supplies the coating liquid, the other communication pipe supplies the air. It will be. Therefore, when the first application liquid is supplied (that is, when the first application liquid is supplied to the application liquid occlusion body not impregnated with the application liquid), the application liquid and the air are rapidly changed, and the application can be performed in a short time. It becomes possible.

<2> A second invention of the present application is the applicator according to the first invention, wherein the front end of each of the communication pipes is inserted forward from the rear end of the application liquid storage body, and the interior of the application liquid storage body is moved forward.

In the applicator according to the second aspect of the invention, the coating solution occlusion body sets a density (density portion) where the density in the vicinity of the front end of each of the communication pipes is set high and a density other than the vicinity of the front end of each of the communication pipes. Part (low density part). Therefore, it is possible to preferentially impregnate the coating liquid inside the coating liquid storage body into the high density portion rather than the low density portion. Thereby, each front end opening of the communication pipe can be surely sealed with the impregnating coating liquid. As a result, when the pressure in the coating liquid tank decreases due to a temperature drop or the like, the coating liquid impregnated in the coating liquid storage body does not remain in the coating liquid storage body, and from the high density portion of the coating liquid storage body It returns to the coating liquid tank properly through the communication pipe.

The applicator according to the second aspect of the present invention provides a difference in density of the coating liquid storage body (that is, a high density portion and a low density portion of the coating liquid storage body), and a front end of each communication pipe is disposed behind the coating liquid storage body. Since it is formed by inserting forward from the end and pressing and compressing the inside of the coating liquid storage body forward, there is no need to provide a density difference in advance in the coating liquid storage body before incorporating the communication tube into the coating liquid storage body. Manufacturing becomes extremely easy.

<3> A third invention of the present application is the applicator according to the first or second invention, wherein a partition wall is provided between the coating solution storage body and the coating solution tank, and the communication pipe is disposed forward of the front surface of the partition wall. Each is protruded, a connecting pipe that can be inserted into the front end opening of the coating liquid tank is protruded behind the rear surface of the partition wall, and the flow path in each communication pipe is passed through the partition wall located in the connecting pipe. It is a requirement that the coating solution tank be detachably attached to the connecting pipe.

In the applicator of the third invention, a connecting pipe that can be inserted into the front end opening of the coating liquid tank is protruded rearward from the rear surface of the partition wall, and the partition wall located in the connecting pipe is connected to each of the communication pipes. By penetrating the flow passage, simply connecting the connecting pipe into the front end opening of the coating liquid tank allows easy connection between the coating liquid tank and the coating liquid storage body via a plurality of communication pipes. In this way, the coating liquid and the air can be circulated. Thereby, when the coating liquid tank and the connecting pipe are connected, the coating liquid and the air are quickly replaced, and writing can be performed in a short time.

In the applicator of the third invention, the coating liquid tank can be replaced, the front end opening of the coating liquid tank is closed with a plug, and a connecting pipe is inserted into the front end opening of the coating liquid tank to plug A configuration in which the coating liquid tank is opened by pressing and removing is preferable.

Since the pen body 2 is located at the axial center of the coating liquid storage body 3, the front ends of the communication pipes 52 are not directly connected to the rear end of the pen body 2 and are not in contact with the pen body 2. Further, the coating liquid is connected through the inside front (high density portion 31) of the coating liquid storage body 3 so that the coating liquid can flow. Further, the front end of each of the communication pipes 52 is located slightly behind the rear end of the pen body 2.
