<p>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.</p> |
