Description

[Detailed description of the invention] Industrial application field This invention can store relatively high viscosity coating liquids such as glue, nail polish, nail polish liquid, etc., and can draw out and apply the liquid with simple operations. Regarding applicator.

Conventional technology There was an applicator that opened a valve when the tip of the applicator was pressed and the coating solution flowed out, but when the tip of the applicator was pressed against the coating surface, the tip was crushed, making it inconvenient to apply to narrow areas, or There was a drawback that the outlet passage for the coating liquid became clogged, which prevented the smooth flow of the coating liquid, resulting in uneven coating.

Problems to be solved by this invention This invention improves the above-mentioned drawbacks and provides an applicator that does not easily collapse even when pressure is applied to the tip of the applicator, has a flexible applicator part, and can apply efficiently. It is to be.

Composition of the device In the figure, 1 is a coating liquid container made of glass, aluminum, or plastics, etc.;
The end tube 3 is screwed into the opening at its tip.

The end cylinder 3 consists of three parts, a large diameter part 4, a medium diameter part 5, and a small diameter part 6, which are connected to each other via step parts 7 and 7'.

Reference numeral 8 denotes a valve seat cylinder, which is usually a bottomed cylinder made of an elastic resin such as polyethylene, and has a collar 9 at its tip and a valve hole 10 at its bottom. Reference numeral 11 denotes a valve receiver cylinder, which is made of the same material and structure as the valve seat cylinder 8, and has a collar 12 and a flow hole 13.
is provided.

The collars 9 and 12 are laminated to form the step 7 of the end tube 3.
It is clamped and fixed between the open end 2 of the container 1 and serves as a packing effect. And the valve receiving cylinder 11 is the container cylinder 1.
The valve seat tube 8 is tightly inserted into the inner circumference of the valve receiver tube 11 on the inner circumference of the tip opening 2 .

14 is a valve with a rod 15 protruding from the tip and a rod 15' protruding from the end.The end of the rod 15' is slidably inserted loosely into the flow hole 13, and is connected to the inside of the valve 14 and the valve receiver. A spring 16 is stretched between the bottom and upper sides of the valve 11, and the valve 14 is springed forward so that the valve hole is always closed.

S is a sponge that absorbs the coating liquid. The coating tip 17 is made of a cylinder 18 made of a hard material such as metal or hard synthetic resin, and is made of a flexible material such as felt or sponge that is tightly fitted with the tip of the cylinder 18 so that the coating liquid penetrates and circulates. It consists of rods 19 made of a network structure. The cylindrical body 18 has through holes 20 and 21 formed at the tip and end of its circumferential surface.

The application tip 17 is slidably inserted loosely into the end tube 3, with its tip protruding from the end tube 3 and its distal end abutting and locking on the tip of the rod 15.

Effects of the invention When the applicator tip 17 is pressed against the coating surface, the applicator tip 17 presses the valve 14, so the valve 14 retreats against the repulsive force of the spring 16, the valve hole 10 is opened, and the coating liquid is released. is in a state where it can be led out to the application tip 17. When the pressure is released, the valve 14 moves forward due to the repulsive force of the spring 16, and the valve hole 10 is closed again.

When the application tip 17 is pressed against the application surface, since it is the rod 18 made of a hard material that comes into contact with the application surface, there is no risk of it being crushed by the pressing force.

The coating liquid that has passed through the valve hole 10 and reached the coating tip first permeates through the through hole 21 into the network structure of the rod 19 and reaches the tip direction by capillary action.
When the more exposed rod 19 is brought into contact with the coating surface, the coating liquid is transferred to the coating surface and can be coated. Excess coating liquid flowing out from the valve hole 10 to the coating tip 17 is occluded by the sponge S and does not leak.
If coating continues and the coating liquid does not flow out sufficiently, pressing the coating tip against the coating surface again will draw out the coating liquid and enable smooth coating.

Since the application tip 17 is not crushed even if the pressure is repeated, smooth application can be continued until the application liquid is consumed.
