Abstract: Flexible container with a sealable closure system comprising an envelope type enclosure having impermeable walls, an opening being defined at an upper portion of the enclosure, two rigid bars being configured to tightly engage edges of the opening in order to seal the enclosure closed, at least one of the two rigid bars being movable, and a system for locking the two rigid bars together. The system for locking the two rigid bars together engages the two rigid bars at both ends of the rigid bars.

Abstract: A waterproof case which seals out sea water and opens upon the application of pressure on two opposite points. The case has a flattened wallet shape and is made from a single piece of synthetic material. The case has two opening edges with at least one opening edge having a compressible strip. The case is absolutely waterproof in a static state until pressure is applied to the edges of the case which forces the opening edges to separate from one another. The case is useful for protecting various objects, such as coins, bank notes, keys, identity papers again water, perspiration, sand, dust and similar objects.

Abstract: The invention concerns a waterproof case, in particular to sea water, opening by mere pressure on two opposite points, consisting of a flattened wallet (1) preferably made in one single piece of synthetic material and comprising on the inner face of the opening edges (5, 6) at least a compressible bonded or sealed joint (7) pressed against the second joint (8) or the opposite edge so as to make it absolutely waterproof when no pressure is exerted, the walls of the device being arranged such that pressure on the side ends of these edges causes them to move apart thus providing access inside the device. The invention is useful for the protection of various objects, such as coins, bank notes, keys, identity papers again water, perspiration, sand, dust and the like.
