DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a finishing agent for clothing,
Spray container that spouts liquids such as glue for clothing, especially
The present invention relates to a sprayer used for an accumulator type spray container.

[0002]

2. Description of the Related Art As is well known, a trigger is attached to a spray container (trigger type spray container) having a trigger type sprayer attached to an opening of a container body. When the trigger is returned, the liquid is sucked up through a tube immersed in the liquid, the cylinder is filled with the liquid, and the trigger is again pulled to release the liquid in the cylinder. Is extruded into a vertical liquid flow conduit, a spin is applied to the flow of the liquid through a horizontal liquid flow conduit and a spin element, and the liquid is finally ejected from a nozzle.

[0003] Such spray containers are widely used as containers for filling liquids such as finishing agents for clothing, sizing agents for clothing, detergents for houses and the like.

[0004] By the way, the spray container as described above,
In general, it is often used intermittently, but even when the liquid pressure of the liquid in the horizontal flow pipe of the sprayer is low, the liquid is ejected from the nozzle through the spin element. When the pressure was low, the liquid material could not be scattered in the form of a mist, but became a water mass and dripped, sometimes causing uneven ejection. The unevenness of spouting is not so problematic in the case of wiping out after spouting, such as liquid detergent for home use, but it is sprayed on clothing like finishing agent for clothing and glue for clothing, and then finished with ironing etc. However, there is a problem that the finish is uneven in the case of performing the above.

As a technique for solving such a problem, a sprayer is provided with a small-diameter cylinder, a large-diameter cylinder disposed in front of the small-diameter cylinder, and a coil spring in the small-diameter cylinder and the large-diameter cylinder. A plunger pump mechanism having a plunger disposed so as to be reciprocally slidable through a pump has been proposed. When the sprayer operates the trigger to increase the hydraulic pressure in the small-diameter cylinder and the large-diameter cylinder to a predetermined hydraulic pressure or more, the plunger moves due to a force difference caused by a difference in cross-sectional area of each cylinder. The liquid material can be ejected at a high pressure.

By the way, in manufacturing the pressure accumulating type spray container, after assembling the sprayer, pressurized air is sent from the lower end of the tube to open and close the plunger.
It is necessary to inspect the tightness of the plunger. In the above-mentioned accumulator type spray container, the tightness between the plunger and the valve seat and the opening / closing operation of the plunger can be inspected. Since the tightness between the moving part and the sliding contact portion of the large-diameter cylinder or the small-diameter cylinder cannot be inspected, the pressure balance of the pressure accumulating mechanism may be lost due to the liquid material leaking from the sliding contact portion, and the device may not operate.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a sprayer capable of detecting the hermeticity of a sliding portion between a sliding portion of a plunger and each cylinder and reliably preventing malfunction of a pressure accumulating mechanism. Is to provide.
