Abstract
A fluid container for packing a product includes a check valve for each container member. A bonding structure of check-valves to a fluid container and a production apparatus of fluid container are disclosed in detail where the check valve is capable of reliably keeping the expansion of the fluid container without any fluid leakage after inflating the fluid container. As the check-valve is bonded to only one of thermoplastic container films, both films of the check-valve are fixed to one of the container films at a plurality of seal portions, thereby preventing the reverse flow by tightly closing the check valve. The plurality of seal portions in a flow pass of the fluid disrupt the fluid flow so as to add resistance to the fluid flow.
