BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side-knock type applicator containing various kinds of application liquids such as writing implement ink, marking pen ink, cosmetic liquid, adhesive and the like. More specifically, the present invention relates to a side knock type applicator provided with a valve device of a type in which a valve is opened by applying a gripping force in a radial direction and the valve is closed by releasing the gripping force.

[0002]

2. Description of the Related Art Conventionally, in this type of applicator, for example,
JP-A-1-131386 discloses a valve opening / closing mechanism in which an axial moving member and a valve seat are connected by a radial moving member, and the axial moving member and the valve are fixed.

[0003]

The conventional valve opening / closing mechanism has a structure in which the valve and the radial moving member are connected and the valve operates simultaneously with the deformation of the radial moving member. Is opened, and there is a risk that the valve mechanism may be inadvertently opened and the coating liquid may flow out excessively.

In the above-mentioned publication, a thread-like member is exemplified as the radial moving member. However, not only the thread-like member has a complicated structure, but also a valve is required in consideration of a variation in the mounting dimensions of the thread-like member. It is difficult in manufacturing to tension the thread-like member at the same time as pressing it against the valve seat. Because, when the installation dimension of the thread-like member is shorter than the setting, even if it can be surely tensioned, the essential valve cannot be pressed against the valve seat and remains open, and does not serve as a valve mechanism from the beginning. . That is, the thread-like member is attached in a slightly slack state longer than the setting. As a result, there is a possibility that the thread-shaped member may be disengaged from the mounting portion at the time of use and become inoperable.

Further, the applicator disclosed in the above publication is
The coating liquid is not supplied to the application destination unless the application destination is directed downward. That is, even if the pinching operation is performed in the radial direction, only the valve mechanism is opened, and particularly when a highly viscous coating liquid is contained, the coating liquid cannot be smoothly discharged to the coating destination.

The present invention has been made to solve the above-mentioned conventional problems, and there is no possibility of inadvertently opening the valve mechanism to cause the coating liquid to overflow excessively or to be inoperable during use. It is an object of the present invention to provide a side-knock type applicator that can smoothly and reliably flow out to a coating destination even if a high-viscosity coating liquid is used, as well as a viscous coating liquid.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a side valve provided with a valve device 3 of a type in which a valve is opened by applying a gripping force in a radial direction and the valve is closed by releasing the gripping force. A knock-type applicator in which a coating liquid is contained in a self-restoring flexible tube 1, and a pressing member 2 is provided at a rear end opening of the flexible tube 1, and a distal end of the flexible tube 1 is provided. A valve device 3 is provided in the opening, and the valve device 3 is provided with a valve body 4 urged rearward by a resilient body to a seat portion 5.
1. The distal end of the pressing member 2 is located at an appropriate distance in the axial direction from the rear end of the valve body 4 so as to apply a radial gripping force to the flexible tube 1. Accordingly, the gist of the present invention is that the distal end of the pressing member 2 abuts on the rear end of the valve element 4 and the valve element 4 is further moved forward to open the valve.

[0008]

When the flexible tube 1 is deformed by the gripping force in the radial direction, the pressing member 2 moves forward in the axial direction, and the front end of the pressing member 2 contacts the rear end of the valve body 4. The pressing member 2 presses the valve body 4 forward to open the valve. Further, since the inside of the flexible tube 1 is in a pressurized state before the valve is opened, it is possible to more smoothly and reliably flow the coating liquid.

When the radial gripping force is released, the pressing member 2 retreats and the valve is closed. The contact between the front end of the pressing member 2 and the rear end of the valve body 4 is released, and an axial gap is formed between the front end of the pressing member 2 and the rear end of the valve body 4. The sex tube 1 is restored to its initial shape.

Further, even if a slight gripping force is applied to the flexible tube by the gap, the pressing member 2 does not come into contact with the valve body 4, so that the valve does not open carelessly.
