Dispensing device

Abstract

Proposed is a dispensing device for a cosmetic product. A flexible inner container is ultrasonically welded with a valve housing. The valve housing is provided with a welding bead which is covered by the inner container during welding. The valve housing has a plate-like connecting section which is welded with an outer side of the inner container.

1 . Dispensing device for dispensing a cosmetic product, with a valve which has a valve housing, and with a flexible inner container which is welded or connected with the valve housing,
 wherein   the valve housing has an at least substantially level and/or thin and/or flange-like and/or plate-like connecting section with which the inner container is exclusively welded or connected, and wherein   the valve housing is welded or connected only with one outer side of the inner container.   
   
   
       2 . Dispensing device as set forth in  claim 1 , wherein the connecting section extends substantially transversely to the longitudinal extension of the valve housing or of an outer container of the dispensing device or of a main delivery direction of the valve. 
   
   
       3 . Dispensing device as set forth in  claim 1 , wherein the valve housing has a tubular section to which the connecting section is adjacent. 
   
   
       4 . Dispensing device as set forth in  claim 1 , wherein the connecting section encloses an inlet or a riser tube of the dispensing device in the manner of a washer and/or protrudes radially downward from the valve housing over the full periphery. 
   
   
       5 . Dispensing device for dispensing a cosmetic product, with a valve which has a valve housing, and with a flexible inner container which is welded with the valve housing,
 wherein   the inner container is ultrasonically welded with the valve housing.   
   
   
       6 . Dispensing device for dispensing a cosmetic product, with a valve which has a valve housing, and with a flexible inner container which is welded with the valve housing,
 wherein   at least one welding bead is arranged or formed on the valve housing prior to welding with the inner container which is covered by the inner container during welding.   
   
   
       7 . Dispensing device as set forth in  claim 6 , wherein the welding bead extends at least substantially around a periphery of the valve housing or is molded on the valve housing. 
   
   
       8 . Dispensing device as set forth in  claim 6 , wherein two welding beads ( 10 ) are provided which are spaced apart and/or run parallel to each other. 
   
   
       9 . Dispensing device as set forth in  claim 1 , wherein at least one of the valve housing or an inner layer of the inner container is composed of polyethylene. 
   
   
       10 . Dispensing device as set forth in  claim 1 , wherein the valve housing or an inner layer of the inner container is composed of polyamide. 
   
   
       11 . Dispensing device as set forth in  claim 1 , wherein the inner container is embodied as a bag. 
   
   
       12 . Dispensing device as set forth in  claim 1 , wherein the inner container collapses upon removal of the product. 
   
   
       13 . Dispensing device as set forth in  claim 1 , wherein the dispensing device has an outer container with which the valve housing is connected in a gas-tight manner or is integrated into the valve. 
   
   
       14 . Dispensing device as set forth in  claim 1 , wherein the inner container is arranged in the outer container and is under external pressure or gas pressure. 
   
   
       15 . (canceled)
