Abstract

A container venting disc is punctuated with gaps around the periphery to allow gases from the interior of the container to vent. An intermediate ridge or layer that abuts or is proximal to the interior edge of the container lip is implemented to prevent the disc from significantly moving laterally and to also center the venting disc within the container mouth. The gap(s) forms a channel in the disc to allow gases to escape between the edge of the container mouth and the container cap. The simplicity of design allows for easy manufacture and simple placement in a container, such as for a jar or bottle.

Claims

exact text as granted — not AI-modified
1 . A venting removable cover for a container opening, the container opening being sealable with a cap, comprising:
 a non-venting outer portion having a predetermined dimension and shape to rest on a lip of the container opening;   a non-venting inner portion that spans an interior face of the container opening;   at least one non-venting intermediate portion bridging the outer portion and the inner portion, shaped to protrude into an interior of the container and being disposed at a position proximal to an interior edge of the lip of the container to prevent slippage of the removable cover from the container opening; and   at least one venting gap through the outer portion, spanning from an outer edge of the outer portion to an outer perimeter formed by the at least one intermediate portion.   
     
     
         2 . The cover of  claim 1 , wherein the shape of the non-venting outer portion is circular. 
     
     
         3 . The cover of  claim 1 , wherein the shape of the non-venting outer portion is rectangular. 
     
     
         4 . The cover of  claim 1 , wherein the shape of the non-venting outer portion is oval. 
     
     
         5 . The cover of  claim 1 , wherein the at least one gap abuts an outer edge of the at least one non-venting intermediate portion. 
     
     
         6 . The cover of  claim 1 , wherein the at least one venting gap is square-shaped. 
     
     
         7 . The cover of  claim 1 , wherein the at least one venting gap is curved in shape. 
     
     
         8 . The cover of  claim 1 , wherein the at least one non-venting intermediate portion is V-shaped. 
     
     
         9 . The cover of  claim 1 , wherein the at least one non-venting intermediate portion is dome-shaped. 
     
     
         10 . The cover of  claim 1 , wherein the at least one gap spans into the non-venting inner portion. 
     
     
         11 . A method for venting gases from a container opening covered by a removable venting disc, the container opening being sealable with a cap, comprising:
 forming a non-venting outer portion of the removable venting disc having a predetermined dimension and shape to rest on a lip of the container opening;   forming a non-venting inner portion of the removable venting disc that spans an interior face of the container opening;   forming at least one non-venting intermediate portion of the removable venting disc bridging the outer portion and the inner portion, shaped to protrude into an interior of the container to prevent slippage of the removable cover from the container opening and disposed at a position proximal to an interior edge of the lip of the container; and   forming at least one venting gap in the outer portion of the removable venting disc, spanning from an outer edge of the outer portion to an outer perimeter formed by the at least one intermediate portion.   
     
     
         12 . The method of  claim 11 , further comprising tightening a cap onto the lip of the container. 
     
     
         13 . The cover of  claim 11 , wherein the shape of the non-venting outer portion is circular. 
     
     
         14 . The cover of  claim 1 , wherein the shape of the non-venting outer portion is rectangular. 
     
     
         15 . The cover of  claim 11 , wherein the shape of the non-venting outer portion is oval. 
     
     
         16 . The cover of  claim 11 , wherein the at least one gap abuts an outer edge of the at least one non-venting intermediate portion. 
     
     
         17 . The cover of  claim 11 , wherein the at least one venting gap is square-shaped. 
     
     
         18 . The cover of  claim 11 , wherein the at least one venting gap is curved in shape. 
     
     
         19 . The cover of  claim 11 , wherein the at least one non-venting intermediate portion is V-shaped. 
     
     
         20 . The cover of  claim 11 , wherein the at least one non-venting intermediate portion is dome-shaped. 
     
     
         21 . The cover of  claim 11 , wherein the at least one gap spans into the non-venting inner portion. 
     
     
         22 . A venting removable cover for a container opening, the container opening being sealable with a cap, comprising:
 non-venting means for resting on a lip of the container opening, having a predetermined dimension and shape;   non-venting means for spanning an interior face of the container opening;   non-venting means for bridging the means for resting on the lip and the means for spanning, shaped to protrude into an interior of the container to prevent slippage of the removable cover from the container opening, and disposed at a position proximal to an interior edge of the lip of the container; and   means for venting gases through the means for resting, spanning from an outer edge of the means for resting to an outer perimeter formed by the means for bridging.   
     
     
         23 . The cover of  claim 22 , wherein the shape of the means for resting is circular. 
     
     
         24 . The cover of  claim 22 , wherein the shape of the means for resting is rectangular. 
     
     
         25 . The cover of  claim 22 , wherein the shape of the means for resting is oval. 
     
     
         26 . The cover of  claim 22 , wherein the means for venting gases abuts the means for bridging. 
     
     
         27 . The cover of  claim 22 , wherein the means for venting gases is square-shaped. 
     
     
         28 . The cover of  claim 22 , wherein the means for venting gases is curved in shape. 
     
     
         29 . The cover of  claim 22 , wherein the means for bridging is V-shaped.
