ある。(Problems to be Solved by the Invention) However, although the above check valve has the advantage of having a simple structure and being able to be provided easily and inexpensively, it has the following serious drawbacks. That is, this check valve has its main body inserted into, for example, a rubber balloon, air is injected from the injection tube to inflate the rubber balloon, and the filled air pressure causes the outer peripheral surface of the two substrates to By applying pressure to bring the inner surfaces of the two substrates into close contact with each other, it is possible to prevent the filled air from flowing out, and a certain degree of backstopping effect can be expected. However, the outer peripheral surfaces of the two substrates are Since the pressure is only increased by a relatively weak predetermined air pressure inside the air conditioner, the check effect is insufficient, and there is a problem in that it is impossible to prevent a considerable amount of air from being released over a short period of time.

し、採用した。(Means for Solving the Problems) As a means for solving the above problems, the present invention consists of a fluid flow pipe formed flat from a plastic film, and a valve body installed in the flow pipe. The valve body is made of a plastic film that is folded in two and has a bent part on the distal end facing toward the fluid inlet in the fluid flow direction and an open part on the proximal end. Further, the flow side edges of the valve body are attached to both side edges of the flow pipe, and the bent portions of the valve body form a closing portion for preventing fluid from flowing out on both sides. developed and adopted a check valve characterized in that a fluid flow path is formed by gaps formed between both inner surfaces of a flow pipe and both outer surfaces of a valve body.

れる。(Function) In the above configuration, when fluid is supplied into the flow pipe from the direction in which the bent portion of the valve body is located, the fluid is formed between both inner surfaces of the flow pipe and both outer surfaces of the valve body. The fluid flows smoothly through the gaps between the balloons, and the fluid flows into the inside of the balloon toy to inflate it.
On the other hand, even if the fluid filled inside the balloon toy, etc. tries to flow out, the pressure of the expanded balloon toy, etc. to restore it or the pressure of the filled fluid pressurizes the outer peripheral surface of the flow pipe, and the valve Because the distal end of the valve body is closed, creating a dead end, the pressure of the fluid entering the valve body from the open part of the valve body increases significantly, and this strong internal pressure strongly applies pressure to both inner surfaces of the valve body. Pressure is applied to expand and expand the valve body to tightly seal the gap and prevent fluid from flowing out. Further, the filled fluid can be smoothly discharged by inserting a thin rod or the like into the sealed gap from the closed side and pushing it open.

Then, insert the check valve V through the opening d of the balloon toy main body a with the installation side of the valve main body 2 located inside the main body, and insert the distal end of the flow pipe 1 into the protrusion of the main body a. As shown in FIG. By heat-bonding f in a linear manner, a balloon toy is constructed that communicates only through the check valves V inside and outside of the main body a.

円滑に行ない得るものである。 When blowing gas into the balloon toy configured as above, use the guide tongue 7 of the flow pipe 1 of the check valve V to position the tip of the air supply port of the air supply device inside the flow pipe 1. When air is supplied, the gas is smoothly filled into the main body a through either or both of the gaps 5, 5, and inflates the toy balloon (see FIG. 7A). When the air supply device is removed after air supply is completed, even if the filled gas tries to flow out due to the restoring pressure of the inflated balloon toy or the gas pressure, the pressure will not apply to the outer peripheral surface of the flow pipe 1. At the same time, since the distal end side of the valve body 2 is closed and becomes a dead end, the pressure of the gas entering the valve body from the open part 4 on the proximal end side of the valve body 2 increases significantly, and the strong internal pressure increases. Both sides of the valve body are strongly pressurized from the inside by pressure, and the valve body 2 is enlarged to reliably seal both gaps 5 and 5, and gas leakage is prevented (as shown in Figures 6 and 7). (see b). Furthermore, when discharging the filled gas, this can be done smoothly by inserting a thin rod or the like into either or both of the sealed gaps 5, 5 from the closed side of the valve body and pushing them open. be.
