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 an applicator with a valve, 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 weight from colliding with the wall of the liquid storage chamber as much as possible during stirring. It is something.

(Summary of the invention) The invention consists of a pen tip 11 protruding from the tip of the barrel 1.
By pushing in, the valve 7 interlocked with the pen tip 11 is opened, and the liquid stored in the liquid storage chamber 2 in the barrel 1 is supplied to the pen tip 11. Weight body 13, 13', 1
3'', the weight bodies 13, 13', 13'' are connected to coil springs 14,
14', the coil spring 14,1
The gist of this applicator is a valve-equipped applicator characterized in that the valve 4' is extended in the liquid storage chamber 2 in the axial direction thereof, and the applicator 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. 11 is a pen nib made of a fiber bundle, a porous sintered body, etc.;
The front shaft 5 is slidably disposed in a hole 12 of the front shaft 5, which has an inner diameter slightly larger than the outer diameter of the front shaft 5. Also, pen nib 1
1 has its rear end 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 for stirring the liquid, and the weight body 13 has a space between it and the bottom part 2a of the liquid storage chamber 2, which respectively constitute the front and rear inner walls of the liquid storage chamber 2 in this example. It is attached at approximately the middle position of the coil spring 14 which is stretched. Such a spherical weight body 13 can be easily attached by making the spherical weight body 13 larger in diameter than the winding diameter of the coil spring 14 and pushing it between the windings. In addition, when the weight body 13 is cylindrical, as shown in FIG.
A recessed groove 13'a is provided in the recessed groove 13'a, and a part of the coil spring 14 is fitted into and engaged with the recessed groove 13'a, or as shown in FIG.
4 is replaced with two coil springs 14', 1 of the same shape.
4', the coil springs 14', 14'
A weight body 13'' may be sandwiched between them.
In the case of the example shown in Fig. 3, in order to prevent the weight body 13'' from coming off, the ends of the coil springs 14' and 14' are attached to the weight body 1.
It is preferable to fit it into the small diameter portions 13''a, 13''a at both ends of the 3''.

In addition, in the embodiment described above, the coil spring 1
4, 14' is shown in which the front end is supported by the ring body 3, but the front end may also be supported by a protrusion provided on the inner surface of the shaft cylinder 1 or another member fixed to the shaft cylinder 1. good.

Next, the liquid stirring operation of the above-mentioned embodiment will be explained.

When stirring the liquid stored in the liquid storage chamber 1, the shaft cylinder 1 is arbitrarily vibrated. Due to this amplitude, the weight bodies 13, 13', 13'' attached to the coil springs 14, 14' vibrate in the longitudinal direction against the elastic force of the coil springs 14, 14'. The bodies 13, 13', 13'' release their vibrations when the shaft cylinder 1 is vibrated at least once, and attenuate as time passes, so the stored liquid absorbs the vibrations of the weight bodies 13, 13', 13''. and the expansion and contraction of the coil springs 14, 14'. Note that as long as the weights 13, 13', 13'' vibrate in the longitudinal direction, they will not collide with the inner wall of the liquid storage chamber 2; Depending on the amplitude direction of the cylinder 1, it may vibrate in a direction perpendicular to the longitudinal direction while remaining eccentric and collide with the inner wall of the liquid storage chamber 2. However, even if it vibrates in this way, the weight bodies 13, 13', 13'' will gradually attenuate the amplitude, so that collision with the inner wall of the liquid storage chamber 2 can be prevented as much as possible.

(Effect of the invention) As described above, according to the invention in which the weight body is attached to the coil spring stretched in the liquid storage chamber, the stored liquid can be stirred by vibrating the weight body with the coil spring. Moreover, it is possible to prevent the weight body from colliding with the inner wall of the liquid storage chamber as much as possible. Further, since the weight body can be vibrated by vibrating the shaft cylinder at least once, the liquid stirring operation is extremely simple.
