弁。[Claims for Utility Model Registration] (1) A flat fluid flow pipe formed by bonding both side edges of two rectangular plastic films, and at least one valve body installed within the flow pipe. The valve body is made of a bi-folded piece of flat plastic film having a closed part on the lower end side and an open part on the upper end side in the direction of fluid flow. Both side edges of the valve body are respectively adhered to both side edges of the flow pipe, and are configured to allow fluid to flow through gaps formed between both inner surfaces of the flow pipe and both outer surfaces of the valve body. The check valve for a vacuum packaging bag is further characterized in that the upper end of at least one of the flow pipes is separated from the valve body by a required length to form a free edge. . (2) A claim characterized in that the length of the free edge of the plastic film of the flow pipe is shorter than the upper edge of the valve body, and the upper end of the valve body protrudes from the free edge. The check valve for vacuum packaging bags described in item (1). (3) A claim characterized in that the inner surface of the flow pipe and the outer surface of the lower part of the valve body are partially bonded.
The check valve for vacuum packaging bags according to either (1) or (2).
