摘要： The invention relates to a pressure vessel (10) for gases, in particular helium, which is characterized in that the pressure vessel has an outer casing having pressure resistance up to an internal gas pressure of at least 10 bar, in that the outer casing of the pressure vessel has at least one highly diffusion-resistant barrier layer having a leak rate for helium at an internal gas pressure of 10 bar and room temperature of preferably less than 10-2 mbar·l/s, and in that the vessel has an accommodating volume for gas at atmospheric pressure of at least 25 liters. The outer casing of the pressure vessel can comprise at least one barrier layer made of a flexible polymer film having a high barrier function or ultra barrier function or at least one highly gas-tight flexible barrier layer made of EVOH. The vessel can be bag-like or, in particular at higher pressures, inherently rigid. High-strength plastics made of fiber granular materials, for example, can be used to produce the layer, which guarantees the high pressure resistance. Seams (12) can be provided, for example in the lateral edge areas, in order to reinforce and stabilize the pressure vessel. The pressure vessel (10) according to the invention can have a ball valve (11) as a closing element in order to remove the gas.
