Valve with safety protrusion

Abstract

The present invention is directed to a valve ( 1 ) for a container comprising a grommet ( 2 ) having a plug system ( 10 ) and defining a channel ( 3 ) with an inlet end ( 4 ) and an outlet end ( 5 ) and a stem ( 8 ) slideably arranged in the channel ( 3 ), whereby the grommet ( 2 ) comprises at least two parts ( 7 ) and ( 8 ) sealingly engaged, said first part ( 7 ) having protrusion within said second part ( 8 ).

1 . A valve for a container, said valve comprising:
 a grommet having a plug system and defining a channel with an inlet end and an outlet end;   a stem slideably arranged in the channel;   wherein the grommet comprising at least two parts and sealingly engaged, said first part having protrusion within said second part.   
     
     
         2 . A valve according to  claim 1 , whereby the grommet is dual injected. 
     
     
         3 . A valve according to  claim 2 , whereby a multipurpose connection ring is injected to the grommet during the same process. 
     
     
         4 . A valve according to  claim 2 , whereby the second part of the grommet is dual injected onto the first part of the grommet. 
     
     
         5 . A valve according to  claim 1 , whereby said part has a hardness higher than the hardness of said part. 
     
     
         6 . A valve according to  claim 1 , wherein at least the first part of the grommet is made of a thermoplastic material, selected from polypropylene or polyethylene, polyamide, ABS, POM or PET. 
     
     
         7 . A valve according to  claim 6 , wherein at least the first part of the grommet is reinforced with fillers and/or glass fibers. 
     
     
         8 . A valve according to  claim 7 , wherein the second part of the grommet is made of a thermoplastic elastomer. 
     
     
         9 . A valve according to  claim 1 , whereby the stem is made of a polyolefine, selected from polyethylene or polypropylene. 
     
     
         10 . A valve according to  claim 9 , wherein the stem is reinforced with fillers and/or glass fibers. 
     
     
         11 . A valve according to  claim 1 , whereby the stem comprises at least one circular sealing lip. 
     
     
         12 . A valve according to  claim 1 , whereby the stem comprises at least two annular resilient lip sections. 
     
     
         13 . An assembly for a container comprising:
 a valve as in  claim 1 ;   a thermoplastic extended portion;   wherein the thermoplastic extended portion, is formed as an integral part of the grommet.
