发明名称 Watertight body for accommodating a photographic camera
摘要 A watertight body for accommodating a photographic camera. The body has a first and a second body shell of rigid polymer material that can be joined together for accommodating a photographic camera. The body has sealing means comprising elastic polymer material provided by a multiple-component injection molding process on an edge of at least one body shell that forms the joint and on surface areas of the body shells. The elastic polymer material is connected to the body shell by chain looping (molecular entanglement) of the polymer materials. The result is that the body is reliably sealed against water and is nevertheless inexpensive and simple to manufacture. For a simple and correspondingly inexpensive recyclability of the body, the body shells can be crushed without separation of the polymer materials using known devices, with the resultant material mix being usable as an admixture for the manufacture of new camera components.
