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.
Waterproof case, in particular to sea water, opening by mere pressure on two opposite points, adapted in particular for swimmers and having the object of protecting various objects, such as coins, bank notes, keys, identity papers against water, perspiration, sand, dust, and the like, characterized by the combination of a case (1) comprising, on the inner face of at least one of the opening edges (5, 6), a compressible bonded or sealed joint (7, 8) which is pressed against the opposite edge or against the second joint so as to make said case absolutely waterproof when no pressure is exerted, the walls of the device being arranged such that pressure on the side ends of said edges causes them to move apart providing access inside the device.
Waterproof case according to either one of the preceding claims, characterized in that it is made of a synthetic material injection molded or thermoformed by blowing.
Waterproof case according to any one of the preceding claims, characterized in that the opening edges (5, 6) have a thickness greater than that of the walls (9, 10) of said case.
Waterproof case according to any one of the preceding claims, characterized in that the joint or joints (7, 8) have a hollow geometry enabling the creation of a sucking effect.
Waterproof case according to any one of the preceding claims, characterized in that the joint or joints (7, 8) are made of an elastomer foam affixed by gluing or heat sealing.
Waterproof case according to any one of the preceding claims, characterized in that one of the outer faces of said case is provided with a loop (13) through which a belt may pass.
Waterproof case according to any one of the preceding claims, characterized in that its sides comprise eyelets (14) capable of accommodating a cord or a chain which passes around the neck or enables hanging said case.
Waterproof case according to any one of the preceding claims, characterized in that a locking system (15) enables interlocking the two opening edges.
