Breathing mask with a sealing lip device

Abstract

A breathing mask device, a sealing lip device for a breathing mask device, a molding tool and a method for producing a corresponding breathing mask device and sealing lip device are described. Also disclosed are ways that make it possible to create a breathing mask device that, with sufficiently strong tightness is distinguished by particular wearing comfort and which moreover can be produced advantageously in times of industrial production standpoints. A breathing mask device for administering a breathable gas is provided and includes a body structure that is sealed against a contact surface of a user's face, a sealing lip device that in combination with the body structure in part defines a breathing mask interior, a gel structure for at least intermittent and partial transmission of the retention forces, acting on the body structure, to the user's face area, and a gel material defining the gel structure is received in a gel receiving chamber defined at least in part by an elastically deformable receiving wall.

1 . A breathing mask device for administering a breathable gas, having:
 a body structure structured to seal against a contact surface of a user's face in use,   a sealing lip device that in combination with the body structure in part defines a breathing mask interior,   a gel structure for at least intermittent and/or partial transmission of the retention forces, acting on the body structure, to the user's face area, and   a gel material defining the gel structure is received in a gel receiving chamber defined at least in part by an elastically deformable receiving wall, wherein elastomer material intended for forming the receiving wall is integrally formed onto a wall portion of the breathing mask device, said receiving wall being separable from the wall portion to form the gel receiving chamber.   
     
     
         2 . The breathing mask device of  claim 1 , wherein the gel receiving chamber comprises a bracing bead portion. 
     
     
         3 . The breathing mask device of  claim 2 , wherein the bracing bead portion extends between the body structure and a user's face sealing lip. 
     
     
         4 . The breathing mask device of  claim 3 , wherein the user's face sealing lip and the receiving wall of the gel structure are integrally formed. 
     
     
         5 . The breathing mask device of  claim 1 , wherein the body structure comprises a hard mask shell or frame element. 
     
     
         6 . The breathing mask device of  claim 1 , wherein the sealing lip device is injection-molded onto the hard mask shell or the frame element. 
     
     
         7 . The breathing mask device of  claim 1 , wherein before the injection molding of the sealing lip device, locally defined reactive zones are generated on the element that forms the body structure. 
     
     
         8 . The breathing mask device of  claim 1 , wherein the reactive zones are generated by corona or plasma treatment. 
     
     
         9 . The breathing mask device of  claim 1 , wherein the reactive zones are generated by adhesion promotion. 
     
     
         10 . The breathing mask device of  claim 1 , wherein the zones intended for detachment of the gel material are locally shielded. 
     
     
         11 . The breathing mask device of  claim 1 , further comprising a filling conduit structure provided on the body. 
     
     
         12 . A sealing lip device for a breathing mask having a body structure, comprising a gel structure having a gel body and an elastomer jacket surrounding at least a portion of the gel body, wherein the jacket is formed in the context of an injection-molding operation by injection molding onto an opposite wall of the body structure and is separable from the opposite wall to form a gel material receiving chamber. 
     
     
         13 . A method for producing a breathing mask device having a body structure and a sealing lip device, wherein the method comprises:
 forming at least one adhesion zone on the body structure;   injection-molding the sealing lip device with an elastomer material onto the body structure in a suitable mold chamber;   forming an adhesive bond between the body structure and the sealing lip device in each adhesion zone; and   creating detachment zones in which the injected elastomer material of one or more portions of the sealing lip device is detachable from the body structure.   
     
     
         14 . The method of  claim 13 , wherein the adhesion zones are generated by corona or plasma treatment. 
     
     
         15 . The method of  claim 13 , wherein the adhesion zones are generated by the application of adhesion promoters. 
     
     
         16 . The method of  claim 13 , wherein the detachment zones are caused by or result from the basic properties of the material comprising the body structure. 
     
     
         17 . The method of  claim 13 , wherein the detachment zones are generated by the application of parting means. 
     
     
         18 . The method of  claim 13 , wherein a receiving chamber for receiving a cushioning filling is formed by lifting the elastomer material in the region of the detachment zone. 
     
     
         19 . The method of  claim 13 , wherein the cushioning filling is formed by a gas or air. 
     
     
         20 . The method of  claim 13 , wherein the cushioning filling is formed by a viscous medium.
