Container cap for improving opening/closing performance of membrane-type valve

Abstract

The present disclosure relates to a container cap for improving the opening/closing performance of a membrane-type valve by stabilizing opening/closing of the membrane-type valve to smoothly discharge or block liquid or gel contents.

1 . A container cap for improving opening/closing performance of a membrane-type valve, the container cap comprising:
 a main body coupled to an inlet of a container and comprising a discharge port formed in an upper end thereof, the discharge port communicated with an outside and an inside of the container;   a membrane-type valve coupled to the discharge port and comprising a fine through-hole in a center portion thereof, wherein the fine through-hole is opened or closed depending on whether the membrane-type valve is pressurized; and   a fixing member coupled between the main body and the membrane-type valve and supporting the membrane-type valve on the discharge port,   wherein the fixing member comprises an extension having a given length extending from a side of the discharge port toward the inside of the container.   
     
     
         2 . The container cap of  claim 1 , wherein the discharge port comprises a latching protrusion formed on an inner circumferential surface thereof. 
     
     
         3 . The container cap of  claim 1 , wherein the membrane-type valve is formed of silicone. 
     
     
         4 . The container cap of  claim 1 , wherein the membrane-type valve comprises an annular protrusion formed along an edge portion thereof. 
     
     
         5 . The container cap of  claim 1 , wherein the fixing member comprises a support protrusion formed on an inner circumferential surface thereof. 
     
     
         6 . The container cap of  claim 1 , wherein the extension has an inner diameter equal to an inner diameter of a portion of the fixing member on which a support protrusion is formed. 
     
     
         7 . The container cap of  claim 1 , wherein the extension has an inner diameter less than an inner diameter of a portion of the fixing member on which a support protrusion is formed. 
     
     
         8 . The container cap of  claim 1 , wherein the extension has an inner diameter greater than an inner diameter of a portion of the fixing member on which a support protrusion is formed.
