Dispensing valve and a container for holding fluid provided with such a dispensing valve

Abstract

The invention relates to a dispensing valve ( 2 ) for dispensing fluid from a container, comprising a central member ( 20 ) provided with a flexible membrane ( 22 ) having at least one slit ( 23 ), a flange ( 40 ) surrounding the central member for attaching the valve to the container and connecting means for connecting the central member to the flange, which connecting means comprise a material hinge ( 25 ). The valve is deformable from a closed position to a dispensing position upon application of pressure to the fluid in the container. The central member is further provided with a support ( 26 ) for the flexible membrane, which support is more rigid than the flexible membrane and extends towards the container in the secured position of the dispensing valve, wherein the material hinge directly couples the support to the flange.

1 . A dispensing valve for dispensing fluid from a container, comprising:
 a central member provided with a flexible membrane having at least one slit;   a flange surrounding the central member for attaching the valve to the container; and   connecting means for connecting the central member to the flange, which connecting means comprise a material hinge, wherein the valve is deformable from a closed position to a dispensing position upon application of pressure to the fluid in the container,   
     characterized in that,
 the central member is further provided with a support for the flexible membrane, which support is more rigid than the flexible membrane and extends towards the container in the secured position of the dispensing valve, wherein the material hinge directly couples the support to the flange. 
 
   
   
       2 . A dispensing valve according to  claim 1 , wherein the material hinge on the one side is located at the upper part of the flange and on the other side at the lower part of the support. 
   
   
       3 . A dispensing valve according to  claim 2 , wherein the material hinge on the one side is located at the inner upper edge of the flange and on the other side at the outer lower edge of the support. 
   
   
       4 . A dispensing valve according to  claim 1 , comprising a second material hinge arranged on the central member. 
   
   
       5 . A dispensing valve according to  claim 4 , wherein the second material hinge is located adjacent the support. 
   
   
       6 . A dispensing valve according to  claim 4 , wherein a first groove is arranged on the central member for forming the second material hinge. 
   
   
       7 . A dispensing valve according to  claim 4 , comprising a third material hinge arranged on the central member between the second material hinge and the center of the flexible membrane. 
   
   
       8 . A dispensing valve according to  claim 7 , wherein the third material hinge is arranged in the vicinity of the slit. 
   
   
       9 . A dispensing valve according to  claim 7 , wherein a further groove is arranged on the central member for forming the third material hinge. 
   
   
       10 . A dispensing valve according to  claim 1 , wherein the support is thicker than the flexible membrane. 
   
   
       11 . Container for holding fluid, provided with a dispensing valve as described in  claim 1 .
