Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a valved applicator for containing a coating liquid such as a correction liquid, ink, and cosmetics. More specifically, the present invention relates to a coating liquid at the time of valve opening. The present invention relates to an applicator with a valve that allows easy adjustment of the outflow amount.

(Prior Art and Problems Thereof) Conventionally, as a valved applicator for containing the above-mentioned coating liquid in a coating liquid chamber, the main body is made of a flexible material, and the tip of the coating body protruding from the tip of the front body is covered during use. It is known that the coating surface is pressed to open the valve, and in this state, the main body made of a flexible material is pressed to adjust the outflow amount of the coating liquid flowing out from the front end opening of the front body. When the outside temperature rises, the pressure inside the coating liquid chamber increases, and a large amount of coating liquid flows out instantly when the valve is opened, or body temperature is transmitted even during use, so the pressure on the main body is adjusted to allow the coating liquid to flow out appropriately. There was a problem that it was difficult. In order to solve these problems, it is considered that the opening amount of the main body front end opening should be made minute, but if the opening amount is made minute, a large amount of pressing force on the main body is required for the coating liquid to flow out. Not only
On the contrary, there was a problem that the outflow of the coating liquid caused a decrease in blurring.

In view of the above problems, the present invention provides a coating liquid outflow restricting portion at the front of the coating liquid, and the coating liquid and the surroundings of the coating liquid between the coating liquid chamber and a sub-chamber communicating with the opening of the coating liquid chamber. It is an object of the present invention to provide a valved applicator in which an elastic liquid repellent member provided between and is provided with a portion for suppressing the outflow of the coating liquid to facilitate adjustment of the outflow amount by pressing the main body.

(Means for Solving the Problem) The present invention provides a main body made of a flexible material having a coating liquid chamber therein, a front body fixed to the front end opening of the main body, and slidable in the front body. The applied body is biased forward by an elastic body so that the tip of the applied body protrudes from the through hole at the tip of the front body and is formed on the front portion of the applied body. In a valved applicator that constitutes a valve mechanism by pressing the valve part to a seat part in the anterior body, the restriction being a gap between the rear tubular part of the anterior body and the rear tubular part of the applicator in front of the applicator body. And a sub-chamber that communicates with the regulating portion is provided in the anterior body, the sub-chamber and the coating liquid chamber are communicated with each other by an opening member, and the opening is covered between the coating body and the opening. As described above, an elastic body made of a coil spring with a small pitch is arranged, and the gap between the wire rods adjacent to the coil spring is set to the above-mentioned small value. The gist of a valved applicator is that it serves as a portion for suppressing the coating liquid flowing out of the space inside the coil spring of the pitch into the sub chamber.

(Examples) Examples will be described below with reference to the accompanying drawings.

Reference numeral 1 is a main body made of a flexible material, and the main body 1 is provided with an opening 1a and a coating liquid chamber 2 for containing a coating liquid such as a correction liquid, an ink or a cosmetic liquid.

Reference numeral 4 denotes a tubular body, and the tubular body 4 is the opening 1 of the main body 1.
It is press-fitted into a, and further, the cylindrical body 4 is screw-fitted,
The tip opening portion 1a of the main body 1 is appropriately fixed by adhesion or the like.
The inner surface step 5a of the front body 5 fixed to the collar 4a
The front end of the main body 1 is pressed and the rear end of the collar 4a is opened.
It is arranged in contact with the front end of a.

Reference numeral 6 denotes an applicator body having a conical valve portion 6a formed at its front end. The applicator body 6 is a coil spring stretched between the rear end of the collar portion 6c and the front end of the tubular body 4. Repellent body 7
The tip end of the applicator body 6 is protruded to the outside of the applicator through the through hole 5d at the tip end of the front body 5, and
The valve portion 6a of the applicator body 6 is arranged in the subchamber 5c in the front body 5 so as to form a valve mechanism by pressing the valve portion 6a of the application body 6 against the conical seat portion 5b formed on the inner surface front portion of the front body 5.

Alternatively, a cylindrical portion may be continuously provided at the rear end of the applicator body 6, and the cylindrical portion may be loosely inserted into the opening 4b of the cylindrical body 4.

Denoted at 8 is a restraint portion which is a gap between the wire rods adjacent to the elastic body 7 made of the coil spring. This restraining portion 8, that is, the gap between the wire rods is 0.3 mm or less when not in use, and when the tip of the applicator body 6 is pressed to the front end surface of the front body 5 against the repulsive force of the applicator body 0 It is preferably provided so as to be 0.01 mm or more.

Reference numeral 9 denotes a rear cylindrical portion 5f of the seat portion 5b of the front body 5 and the coating body 6
This is a restricting portion constituted by a minute gap between the valve portion 6a and the rear cylindrical portion 6d.

The front body 5 is screwed, press-fitted into the front end opening (1a) of the main body 1,
It is fixed by an appropriate fixing means such as adhesion, and has a through hole 5d at the tip and a conical seat portion 5b inside the rear part of the through hole 5d.

Reference numeral 10 is a cap, and 10a is a rib formed on the inner surface of the opening of the cap, which can be fitted and fixed to the rib 5e formed on the outer surface of the rear portion of the front body 5.

Next, the operation will be described.

When using, the body 1 is turned downward, and the through hole 5d at the tip of the front body 5 is used.
The tip of the more protruding coating body 6 is brought into contact with the surface to be coated and pressed against the elastic force of the elastic body 7 made of a coil spring. When the main body 1 is pressed, the coating liquid in the coating liquid chamber 2 flows out from the opening 4b, which is the coating liquid outlet of the coating liquid chamber 2, into the repellent body 7 made of a coil spring, and the coil spring The outflow amount is stretched by the restraining portion 8 formed by the gap between the adjacent wire rods, and the sub chamber 5
It is drained into c. When the pressure is further pressed, the coating liquid stored in the sub chamber 5c is buffered by the air in the sub chamber 5c, the outflow amount is further stretched by the regulating portion 9, and the coating liquid flows out to the coated surface in an appropriate amount.

That is, in the present invention, the coating liquid in the coating liquid chamber 2 when the main body 1 is pressed is stretched by the restraining portion 8, buffered in the sub chamber 5c, and further regulated by the regulating portion 9 so that the front body 5 is transparent. Hole 5d
It has been more like a spill. Therefore, the coating liquid chamber 2
The coating liquid inside does not directly flow out from the through hole 5d of the front body 5, and the amount of the coating liquid flowing out can be easily adjusted by pressing the main body 1. Moreover, even when the external temperature rises, the coating liquid in the coating liquid chamber 2 does not directly flow out from the through hole 5d of the front body 5 but flows into the sub chamber 5c when the valve is opened. The pressure condition will be buffered.

Therefore, when the valve is opened, a large amount of coating liquid does not flow out instantly.

As described above, in the present example, the restraining portion 8 is provided on the elastic body 7 made of a coil spring so that the coating liquid is prevented from sticking to the inhibiting portion 8 due to expansion and contraction of the elastic body 7. In addition, the liquid wall 11 in the restraining portion 8 is made thin (see FIG. 2), and the air exchange portion can be made long.

Further, the fixing structure of the cylindrical body 4 is for preventing the leakage of the coating liquid from the fixed portion of the main body 1 and the front body 5, and
The cylindrical body 4 is not necessary as long as the fixing means between the front body 5 and the front body 5 has excellent sealing performance, and the diameter of the opening portion 1a of the main body 1 is reduced so that (the opening portion 4a of) the cylindrical body 4 It may be used as a substitute.

(Advantages of the Invention) As described above, the present invention forms the regulation part in front of the application body, and provides the sub-chamber in communication with the regulation part in the anterior body. The sub-chamber and the coating liquid chamber are connected to each other. An elastic body made of a small-pitch coil spring is arranged between the coating body and the periphery of the opening so as to cover the opening, and the gap between the wire rods adjacent to the coil spring is restrained. Therefore, it is easy to adjust the outflow amount of the coating liquid during use, the thickness of the coating liquid wall in the restraining portion is thin, and the air exchange portion is provided for a long length around the effective coil circumference of the coil spring. By doing so, the flow of the coating liquid between the coating liquid chamber and the sub chamber becomes smooth, and continuous coating is also excellent.
