  • Patent number: 12515867
    Abstract: A fluid container has a first and second flexible membrane forming at least one chamber, a channel configured to receive pressurized inert gas, and one or more check valve assemblies disposed therebetween. The one or more check valve assemblies is formed from a continuous third flexible membrane folded at an apex, and configured to provide the flow of pressurized fluid in one direction upon inflation, from the channel to the at least one chamber, while restricting flow in the opposite direction. Advantageously, the one or more check valve assemblies do not require pre-printing or electronic registering and are larger thus allowing for an inflation flow rate at least twice that of conventional inflatable packaging systems. The third flexible membrane may also be configured in an S-bend thereby providing a single check valve. A port may be disposed at the inlet of the channel to facilitate filling of the fluid.
