Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a fluid-filled container having a desired shape, such as a flat shape like an air pillow, a floating bladder, or a donut shape like a rubber boat.

As shown in FIG. 1, the structure of the conventional plug of this type of container includes a fluid-filled container body 1 made of a flexible base material, and a valve 2 attached to the body 1 to allow fluid to flow in or out. hollow member 3, and the member 3
A plug 5 is provided through a connecting band 4 to the main body 1, and in order to flow a fluid consisting of gas or liquid into the main body 1, the fluid is introduced into the hollow part of the member 3 by applying pressure or the like. To open the valve and allow fluid to flow out, first remove the stopper 5 from the member 3;
Next, the member 3 is pressed from the outside to deform the valve 2.
In reality, this is done through complicated operations such as breaking the tight contact between the end portion of the member 3 and the end portion of the member 3.

The present invention particularly relates to the structure of a fluid-filled container that allows fluid such as gas or fluid to flow out easily from the container, and will be specifically explained below with reference to the drawings.

In FIG. 2, 11 is a water bladder, air pillow, or swim bladder formed by molding a flexible and mechanically superior base material such as polyethylene, polypropylene, or vulcanized rubber sheet into a predetermined shape or using other means. , a fluid-filled container body such as a rubber boat, and 31 is a hollow member attached to a desired location of the container 11;
Inside the container of the member 31, there is a member 3 as shown in the figure.
A valve 2 has a size that closes the hollow part of the member 31, and a part of the valve 2 is connected to the member 31, and is opened when fluid flows in, and closes the opening of the member 31 by internal pressure after the fluid flows in.
1 is provided.

51 is a plug provided on the member 31 via the connection band 41; 6 is a fluid outflow auxiliary body with a flat cross section provided at the end of the connection band 41; It is said to be smaller than the department.

These valve 21, member 31, connecting band 41, plug 5
1 and the auxiliary body 6 can be made by integrally molding polyethylene or the like.

FIG. 3 shows the state of use, in which the stopper 51 is removed from the member 31 and the auxiliary body 6 is inserted into the hollow part 7 of the member 31.
The valve 21 is pushed open by the auxiliary body 6. By pushing the container in this state, gas such as air and fluid such as liquid such as water can continuously flow out.

FIG. 4 shows another example, in which the auxiliary body 6 is formed into a hollow body having an outer diameter that allows it to be inserted into the hollow portion 7 of the member 31, and is attached to the member 31 via a connecting band 42. The auxiliary body 6 in this illustrated example has the advantage that by being inserted into the hollow member 31, it pushes open the valve 21 and forms an inlet or an outlet for fluid.

Note that the shape of the auxiliary body 6 or the attachment position to the connecting band 41 or the member 31 are not limited to the above examples.

Since the structure of the present invention is provided with the auxiliary body as described above, when making the enclosed gas or fluid flow, the auxiliary body is inserted into the hollow part of the member and the valve is pushed open. Therefore, it has the feature that fluid can be easily drained.
