DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a finishing agent for clothing,
The present invention relates to a spray container for ejecting a liquid material such as an adhesive for clothing.

[0002]

2. Description of the Related Art As is well known, a trigger is sprayed on a spray container (trigger type spray container) in which a trigger type sprayer is attached to an opening of a container body, and air in a cylinder is discharged to the outside. When the trigger is returned, the liquid material is sucked up through a tube immersed in the liquid material, the liquid material is filled in the cylinder, and the trigger is pulled again, thereby pushing out the liquid material in the cylinder and causing a vertical liquid passage. In addition, there is a type in which a spin is given to the flow of the liquid material through a horizontal liquid passage pipe and a spin element, and finally the liquid is 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]

The above-described spray container is generally used intermittently in many cases. However, even when the liquid pressure of the liquid material in the horizontal flow pipe of the sprayer is low, the spray container is often used intermittently. Since the liquid material is ejected from the nozzle through the spin element, the liquid material cannot be scattered in the form of a mist at the time of low pressure in the early stage and the late stage of the ejection, so that the liquid may drop as a water lump, resulting in 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, Japanese Utility Model Laid-Open No.
Japanese Patent No. 37554 discloses a pressure-accumulation type spray container. However, in such a container, when used several times, the liquid content leaks from the groove of the residual pressure removing mechanism little by little, and the content is increased. If the material is easily solidified, such as a glue, there is a risk that subsequent spraying will be hindered.

Accordingly, it is an object of the present invention to satisfactorily squirt contents which are easy to solidify, such as a sizing agent. It is an object of the present invention to provide a spray container capable of uniformly ejecting a liquid material while suppressing spraying.

Next, the operation of the spray container 1 will be described with reference to FIG.
This will be described with reference to FIGS. In these figures, only the sprayer 3 is shown for convenience. The symbol L in the drawing indicates a liquid material.

When spraying a liquid material with the spray container 1, first, as shown in FIG. 1, the sprayer 3 is attached to the mouth of the container body 2 filled with the liquid material. Then, holding the container body 2 and operating the trigger 8 with one hand, the large-diameter cylinder 13 is moved rearward to gradually raise the liquid material in the container body 2 through the tube 10 and further into the tube portion 9c. The ball valve 17 is pushed up and guided into the small-diameter cylinder 11.

Further, the turning operation of the trigger 8 is repeated, and as shown in FIG. 3, the liquid material L guided into the small-diameter cylinder 11 is supplied to the large-diameter cylinder 1 through the liquid passage hole 120a.
Let the liquid pass through the 3 side. When the rotary operation of the trigger 8 is further performed, the inside of the small-diameter cylinder 11 and the large-diameter cylinder 13 is filled with the liquid material L, and the hydraulic pressure is gradually increased, but the hydraulic pressure is higher than the urging force of the coil spring 15. When it is low, the tip portion 120b of the main plunger 120 contacts the contact portion 13f of the large-diameter cylinder 13 due to the urging force of the coil spring 15, and the spin element portion 1 in front of the contact portion 13f.
The liquid flow to 3e is shut off.

When the trigger 8 is further pulled after the pressure is accumulated at a predetermined pressure, as shown in FIG. 4, the small-diameter cylinder 11 and the large-diameter cylinder 13 (cylinder portion 13b)
The difference in the cross-sectional area between the large-diameter cylinder and the large-diameter cylinder causes a force difference due to the difference in the cross-sectional area between the large-diameter cylinder and the large-diameter cylinder. 13 and the distal end portion 120a of the main plunger 120 are separated from each other.

Then, as shown in FIG.
Is pulled to the end point, the sliding portion 120c of the main plunger 120 is connected to the liquid passage groove 11g of the small-diameter cylinder 11.
The liquid L reaches the upper part, moves through the gap between the outer peripheral surface of the main plunger 120 and the inner peripheral surface of the small-diameter cylinder 11, and flows into the liquid passage hole 11d. Then, the liquid flow path 1 of the gas-liquid introduction path 14 defined by the resection 70a
4a (see FIG. 2), the liquid material L in the small-diameter cylinder 11 flows into the container body 2 through the gas-liquid introduction holes 7b and 9g, so that the liquid pressure in the small-diameter cylinder 11 and the large-diameter cylinder 13 decreases. . Thereafter, the distal end portion 120b of the main plunger 120 seals the contact portion 13f of the large-diameter cylinder 13 by the elastic force of the coil spring 15, and the nozzle portion 1
Since spraying from 3c cannot be performed, spraying at a low spray pressure can be suppressed. In addition, the air hole 11
Since outside air flows into the container main body 2 through c, the deformation of the container main body 2 is suppressed.

As described above, the spray container 1 according to the present embodiment comes into contact with the inner surface of the pipe fitting wall portion 7a constituting the horizontal conduit 4 of the sprayer body 7 and the outer peripheral surface of the small-diameter cylinder 11, and Since the rib 70a that defines the liquid introduction path 14 between the liquid flow path 14a and the gas flow path 14b is provided, even a solidified content such as a glue can be squirted well.

In addition, the plunger pump mechanism 6 is disposed in the horizontal pipeline 4, a nozzle 13c is provided in front of the large-diameter cylinder 13, and the open position after accumulating the pressure is substantially true of the spin element 13e. At the same time as when the residual pressure is removed (at the end point of the trigger 8, the liquid material passes through the gap between the outer peripheral surface of the main plunger 120 and the inner peripheral surface of the small-diameter cylinder 11 and enters the liquid passage hole 11 d. At the same time as the hydraulic pressure is reduced).
b and the contact portion 13f are in contact with each other to be in a sealed state, and the spray can be stopped without leaving any pressure for spraying to the spin element portion 13e. Therefore, it is possible to make the liquid drain better, and it is possible to surely prevent the liquid from dripping as compared with the related art.

Since the small-diameter cylinder 11 is assembled to the sprayer main body 7, the sprayer main body 7 itself does not require complicated molding, thereby facilitating assembling. Design changes can also be made easily.

The liquid material that can be jetted out of the spray container according to the present invention is, for example, a finishing agent for clothing having a viscosity of about 1 cp to 20 cp, and a pasting agent for clothing that can be jetted with this type of trigger type spray container. Of course,
It was not possible to jet uniformly with a conventional spray container 21
a finish for clothing having a viscosity of about cp to 100 cp,
Liquid substances such as clothing paste can also be sprayed uniformly while suppressing dripping.

In the spray container according to the present invention, like the spray container 1 'of the embodiment shown in FIG. 6, the coil spring 15 for urging the tip of the plunger 12 toward the nozzle portion 13c is provided with the large diameter. The coil spring 15 is interposed between the rear end of the sliding portion 121a of the plunger 12 that slides in the cylinder 13 and the front end of the small-diameter cylinder 11 so that the coil spring 15 is brought into non-contact with the ejected liquid material. 1
5 may be prevented so that a liquid material can be ejected regardless of the liquid property.

The spray container according to the present invention is not limited to the above-described embodiment, and its size, shape, and the like can be appropriately changed without departing from the object of the present invention.

For example, in the spray container 1 of the above embodiment, the horizontal pipe 4 of the sprayer body 7 is in contact with the outer peripheral surface of the small-diameter cylinder 11 and the gas-liquid introduction path 14 is in gas communication with the liquid flow path 14a. Rib 7 defining road 14b
Is provided with the 0a, it may be provided with ribs defining a contact and a gas-liquid introduction passage on the inner peripheral surface of the horizontal line to the small diameter cylinder 11 side and the liquid flow through passage and the gas flow through passage. Further, the sectional shape of the small diameter cylinder 11 and horizontally flattened squamous sectional shape may define a gas-liquid introduction passage into the liquid flow through passage and the gas flow through passage.
