Description

[Detailed description of the invention] (Field of industrial application) The present invention opens a valve linked to the pen tip by pushing the pen tip protruding from the tip of the barrel, and the liquid storage chamber inside the barrel is opened. The present invention relates to a valve-equipped applicator which supplies a stored liquid to a pen tip and has a stirring weight disposed in the liquid storage chamber.

(Prior art and its problems) The above-mentioned applicator with a valve can be said to be suitable when using a liquid containing a volatile organic solvent because the valve can be used to shut off communication between the outside air and the liquid storage chamber. However, since colorants with high specific gravity such as pigments and synthetic pearlescent agents tend to settle over time, it is necessary to redisperse the colorant that has settled or has solidified after settling before use. Therefore, in such a valve-equipped applicator, a spherical, annular, or other weight body that can be moved turbulently by vibrating the barrel is placed in the liquid storage chamber, thereby making it possible to stir the liquid. ing.

However, the weight body, which oscillates due to the vibration of the shaft cylinder, collides with the wall of the liquid storage chamber.
This impact may cause problems in the connection of various parts, and in particular, the impact when the weight collides with the bottom wall of the liquid storage chamber may cause damage if the pen tip is press-fitted into the valve. If the connection becomes loose, the pen tip may fall out, or if the pen tip is placed in contact with the valve, the pen tip may fall out.

(Purpose of the invention) The present invention was devised in view of the above-mentioned conventional problems, and aims to provide an applicator with a valve that can prevent the pen tip from slipping out or falling off during stirring as much as possible.

(Summary of the invention) This invention opens a valve linked to the pen tip by pushing the pen tip protruding from the tip of the barrel, and supplies the liquid stored in the liquid storage chamber in the barrel to the pen tip. In the applicator with a valve, in which a weight for stirring is disposed in the liquid storage chamber, the rear part of the liquid storage chamber is provided with an inclined surface that is inclined with respect to the axis with which the weight collides when the weight moves rearward. The gist of the present invention is to provide an applicator with a valve, which is characterized by the provision of a valve, and meets the above-mentioned purpose.

(Example) Hereinafter, the present invention will be described in detail based on an example shown in the accompanying drawings.

In FIG. 1, reference numeral 1 is a shaft cylinder,
A liquid storage chamber 2 is provided within the barrel 1 in which liquid for writing, makeup, etc. is stored. Reference numeral 3 denotes a ring body having a valve hole 4 in the center that communicates with the liquid storage chamber 2, and the ring body 3 is connected to the rear end of the front shaft 5 and the shaft cylinder 1.
The flange 3a is clamped by the inward protrusion 6 of the shaft cylinder 1.
is fixedly placed. Reference numeral 7 denotes a valve having a substantially conical valve portion 8 having an inclined outer surface at the rear portion, and the valve 7 is urged forward by an elastic member 9 such as a spring stretched between it and the ring body 3. The valve part 8 is connected to the valve hole 4.
It is in close contact with the Reference numeral 10 denotes a liquid-containing member such as a sponge, which is disposed in a space within the front shaft 5 and can temporarily store liquid flowing out from the valve hole 4 when the valve 8 is opened. Reference numeral 11 denotes a pen nib made of a fiber bundle or a porous sintered body, and the pen nib 11 has a hole 1 in the front shaft 5 that has an inner diameter slightly larger than the outer diameter of the pen nib 11.
2, so that it can be slid freely. Also, pen tip 11
The rear end of the pen is in contact with the front end of the valve 7, and by pushing in the pen tip 11, the valve 7 can be moved back together. Reference numeral 13 denotes a spherical weight body (2 in the figure) for stirring the liquid arranged in the liquid storage chamber 2.
).

Although the above-mentioned configuration is not much different from the conventional one, the present invention includes an inclined surface in the rear part of the liquid storage chamber 2 that can disperse the impact force exerted by the weight body 13 during liquid stirring to other than the rear of the axis of the shaft cylinder 1. This is largely different in that it includes the following, which will be explained in detail below.

In the example shown in FIG. 1, a conical part 14 whose diameter gradually decreases toward the rear is integrally formed at the rear part of the liquid storage chamber 2 by pressing, molding, etc., and an inclined surface 15 inclined with respect to the axis is formed. It was established.

In the example shown in FIG. 2, a tail plug 17 having a conical recess 16 whose diameter gradually decreases toward the rear is connected to the rear part of the liquid storage chamber 2, and an inclined surface 1 inclined with respect to the axis is connected to the rear part of the liquid storage chamber 2.
5a is provided.

In the example shown in FIG. 3, the rear part of the shaft cylinder 1 (liquid storage chamber
The rear part) is formed into a conical shape that gradually becomes smaller in diameter toward the rear, and is provided with an inclined surface 15b that is inclined with respect to the axis.

In the example shown in FIG. 4, a piece 18 having an inclined surface 15c at the front end is movably or immovably provided at the rear part of the liquid storage chamber 2.

As can be understood from the example described above, in the present invention, inclined surfaces 15, 15a, 15b are provided at the rear part of the liquid storage chamber 2, which are inclined with respect to the axis with which the weight body 13 collides when moving backward during liquid stirring. , 15c, the impact force exerted by the weight body 13 is dispersed into a component perpendicular to the inclined surfaces 15, 15a, 15b, 15c, which are the collision surfaces, and a component parallel to the collision surfaces.
It will not act on the rear part of the axis. Therefore, since no force that could move the pen tip 11 forward of the axis is directly applied to the pen tip 11, the pen tip 11 will not slip out or fall off.

(Effect of the invention) As described above, according to the present invention, in which the rear part of the liquid storage chamber is provided with an inclined surface that is inclined with respect to the axis with which the weight collides when the weight moves backward during liquid stirring, the weight Since the impact force exerted by the pen can be dispersed to areas other than the rear of the axis, no force that could move the pen tip forward of the axis acts directly on the pen tip, thus preventing the pen tip from slipping out or falling out during stirring. be able to.
