20090057181 | Multi-Purpose Waterproof Case - An air-tight polygonal, resembling a rectangular shape of, container for accommodating camera for underwater use. The airtight container consists of a casing and a lid, sealing by a pair of clamps together with a pair of clamping device each (part) with an about horizontal groove on the inner surface of the clamping device for the casing and lid to slide into the brackets to tight-fit easily. Both the casing and the lid do not stand alone, but form with integral parts to form the casing compartment and the lid section. On each of the casing compartment and the lid section are two slots on each of the width-long sides. The slots will tight-fit with the locking projections in the inner bottom of the clamping device, also with two locking projections on each of the width-long side. The sealing effect of this new invention is further guaranteed by the use of a flange on each of the length-long side so that the container is sealed and will not be fallen apart because of external forces. | 03-05-2009 |
