Container closure having an air intake valve

Abstract

A container having an air intake value, enables a minimal amount of air to enter the container that the one way directional airflow eliminates the flexible walls of a container from being drawn inward and container distortion (product paneling) due to temperature and altitude changes. The inside design of the cover cap makes direct contact with the valve top slit area but generally not the outside of the slit area. With the top cover cap in place and covering the soft concave valve, the slits are restricted from opening outward because to the bottom contour contact fit of the cover cap. The flexible slit valve pieces are unrestricted from moving inward and open automatically to let air in when necessary and eliminating the paneling affect. In the closed position the top snap cover cap is designed not to be completely airtight with two butt joint areas on the hinge side of the cap. This enables air to enter around the hinge, up into the cap interior circumference, down through the flexible valve and into the main container.

1 . A container closure, comprising: 
 a cover cap; and    passage permitting air to enter into said container when said closure is in a closed position.    
     
     
         2 . The closure of  claim 1 , further comprising a valve member.  
     
     
         3 . The closure of  claim 2 , wherein said valve member includes at least one opening.  
     
     
         4 . The closure of  claim 3 , wherein said passage and said at least one opening are in communication.  
     
     
         5 . The closure of claims, wherein said communication is facilitated by contact of the underside of the cover cap with the surface of the valve.
