Cap for an Aerosol Container or a Spray Container

Abstract

In order to seal a spray cap acoustically, a cap 7 with a button 6 is provided with an elastic connection 49 between the button 6 and the cap 7 so as to form an acoustic seal 49 of the cap 7. The seal 49 is designed as a folded arrangement.

1 . A cap ( 7 ) with a button ( 6 ) for actuating a valve of a container ( 1 ), in particular of an aerosol container or spray container, the button ( 6 ) being intended to act against a separate, angled connection piece, in particular an angled spray channel ( 10 ), and thus against a stem ( 11 ) of the container ( 1 ) in order to deflect the stem ( 11 ) upon manual actuation of the button ( 6 ) and in order therefore to open the valve, as a result of which a product contained in the container ( 1 ) can move out through the stem ( 11 ) and through a product dispensing opening ( 3 ) provided on the cap ( 7 ), in so doing passing through the spray channel ( 10 ), and a flexible connection between the button ( 6 ) and the cap ( 7 ) forming an acoustic seal ( 49 ) of the cap ( 7 ), wherein the seal ( 49 ) is designed as a folded arrangement which is stretched when the button ( 6 ) is actuated and which is returned into the original folded arrangement when the button ( 6 ) moves back. 
     
     
         2 . The cap as claimed in  claim 1 , wherein the button ( 6 ) is round, preferably circular or oval, and the seal ( 49 ) runs annularly around the button ( 6 ). 
     
     
         3 . The cap as claimed in  claim 1 , wherein the seal ( 49 ) is designed as a bellows arrangement. 
     
     
         4 . The cap as claimed in  claim 1 , wherein the seal ( 49 ) has a peripheral single fold. 
     
     
         5 . The cap as claimed in  claim 1 , wherein the seal ( 49 ) is connected to the cap ( 7 ) and to the button ( 6 ) in a one-piece construction. 
     
     
         6 . The cap as claimed in  claim 1 , wherein the seal ( 49 ) is designed as a separate component which can be inserted as a plug connection between the cap ( 7 ) and the button ( 6 ). 
     
     
         7 . The cap as claimed in  claim 1 , wherein the button ( 6 ) is connected to the area ( 29 ) of the cap ( 7 ) via a hinge ( 5 ). 
     
     
         8 . The cap as claimed in  claim 1 , wherein the seal ( 49 ) hermetically seals off the surface between the cap ( 7 ) and the button ( 6 ). 
     
     
         9 . The cap as claimed in  claim 1 , wherein the spray channel ( 10 ) is designed as a spray angle which is connected to the cap ( 7 ) in the area of the product dispensing opening ( 3 ). 
     
     
         10 . The cap as claimed in  claim 9 , wherein the material thickness of the seal ( 49 ) in the area ( 29 ) of the product dispensing opening ( 3 ) is less than the material thickness in the area ( 30 ) of the seal ( 49 ) farthest away from the product dispensing opening ( 3 ). 
     
     
         11 . The cap as claimed in  claim 2 , wherein the material thickness of the seal ( 49 ) from the area ( 29 ) of the product dispensing opening ( 3 ) to the far area ( 30 ), continuously increases from 0 to 180 degrees and continuously decreases from 180 degrees to 360 degrees. 
     
     
         12 . The cap as claimed in  claim 10 , wherein the material thickness of the seal ( 49 ) in the area ( 29 ) located at the product dispensing opening ( 3 ) is between 0.4 and 0.6 mm and, at the far area ( 30 ), it is between 0.1 and 0.2 mm. 
     
     
         13 . The cap as claimed in  claim 1 , wherein the seal ( 49 ) is made of an elastic elastomer material, such as soft and flexible polypropylene (PP) or polyethylene (PE). 
     
     
         14 . The cap as claimed in  claim 1 , wherein the cap ( 7 ) and seal ( 49 ) and button ( 6 ) are made in one piece from elastomer material. 
     
     
         15 . The cap as claimed in  claim 14 , wherein the cap ( 7 ) is made of two-component elastomer.
