Patent ID: 8684003

Claim:
A breathing mask device for administering a breathable gas, comprising: a sealing lip device structured to seal against a contact surface of a user's face in use; a body structure that, in combination with the sealing lip device, in part defines a breathing mask interior; a gel structure for at least one of intermittent and partial transmission of retention forces, acting on the body structure, to the user's face; and a gel material defining the gel structure is received in a gel receiving chamber defined at least in part by the body structure and an elastically deformable receiving wall that is attached to the body structure at at least two locally defined reactive zones, wherein the elastically deformable receiving wall is integrally formed onto a wall portion of the body structure at the at least two locally defined reactive zones of the breathing mask device, such that the elastically deformable receiving wall is conformable to the wall portion of the body structure, and wherein said elastically deformable receiving wall is separated from the wall portion between the at least two locally defined reactive zones to form the gel receiving chamber when the gel material is inserted between the elastically deformable receiving wall and the wall portion of the body structure.
