Abstract
A flexible pressure vessel 20 having an aperture 44 through one wall 30 of the vessel 20, which aperture 44 can be closed by a closure flap 50 having sufficient surface area of adhesive 52 to completely surround the aperture 44. The adhesive 52 has sufficient peel strength to prevent the vessel 20 from being reused after closure, and the vessel 20 is capable of withstanding a pressure differential of at least 75 kPa for at least thirty minutes.
