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.
Claims17
A waterproof case which opens by mere pressure on two opposite points, comprising:
- an enclosure for holding and protecting various objects, said case being resistant to the introduction of foreign matter;
- at least two walls having first and second opening edges;
- a compressible first joint strip affixed to the first opening edge;
- a compressible second joint strip affixed to the second opening edge;
- each of the first and second joint strips comprising a sealing recess wherein the sealing recesses are arranged directly opposite one another;
- each of the first and second joint strips being affixed to an inner face of one of the opening edges for producing a sealed joint;
- wherein the case is absolutely water proof when the first joint strip is pressed against the second joint strip when no pressure is exerted on the case, and
- wherein the sealed joint has a geometry adapted to produce a sucking effect between the first and second opening edges.
A waterproof case which opens by mere pressure on two opposite points, comprising:
- an enclosure for holding and protecting various objects, said case being resistant to the introduction of foreign matter;
- at least a first wall and a second wall, said first wall having a first opening edge and said second wall having a second opening edge, the first and second opening edges defining a sealed joint;
- a first joint strip affixed to the first opening edge and having at least one engaging recess;
- a steel strip disposed on the first opening edge;
- a second joint strip affixed to the second opening edge and having at least one engaging recess;
- and
- a steel strip disposed on the second opening edge,
- each of the engaging recesses being arranged directly opposite one another;
- wherein the enclosure is normally biased to a closed sealed state with the first joint strip contacting the second joint strip,
- wherein the enclosure becomes open and unsealed when the first and second steel strips experience a compressive force, and
- wherein the sealed joint has a geometry adapted to produce a sucking effect between the first and second opening edges.

- a first steel strip disposed on the first opening edge between the first joint strip and the first opening edge;
- a second joint strip affixed to the second opening edge and having at least one engaging recess;
- a second steel strip disposed on the second opening edge between the second joint strip and the second opening edge;
- each of the first and second sealing recesses being arranged directly opposite one another;
- the enclosure being normally biased to a closed sealed state with the first joint strip contacting the second joint strip,
- wherein the enclosure becomes open and unsealed when the first and second steel strips are deflected away from one another, and
- wherein the sealed joint has a geometry adapted to produce a sucking effect between the first and second opening edges.
