Self-venting lid for containers

Abstract

The present invention relates generally to self-venting food storage containers that release pressure build up inside the sealed container during storage or cooking. The silicone food storage container includes a venting aperture configured to release pressure build-up from within the container. The venting aperture is defined by a barrier and includes an area of silicone that is thinner than the thickness of the material of the lid, so any tear in the venting aperture will not tear past the circumference of the barrier. The silicone food storage container is also dishwasher safe, microwave safe, and, for the most part, unbreakable.

1 . A self-venting food storage container comprising:
 a lid and a base,   wherein the base has at least one sidewall extending from a bottom forming a receptacle for storing food,   wherein the sidewall has a rim,   wherein the lid has a recess configured to selectively receive the rim of said base, such that connecting of said rim to said recess seals the container,   wherein the lid has a thickness and a venting aperture,   wherein the venting aperture has a thickness thinner than the thickness of the lid;   wherein the lid and the venting aperture are each part of a single unitary structure formed from silicone, and   wherein the venting aperture has a normally sealed slot cut through the lid configured to release pressure-build up in the container.   
     
     
         2 . The self-venting food storage container of  claim 1 , wherein the food storage container is made entirely of silicone. 
     
     
         3 . The self-venting food storage container of  claim 2 , wherein the silicone is food-grade silicone. 
     
     
         4 . The self-venting food storage container of  claim 1 , wherein the inner surface of the receptacle is smooth. 
     
     
         5 . The self-venting food storage container of  claim 1 , wherein the inner surface of the lid has a smooth finish. 
     
     
         6 . The self-venting food storage container of  claim 1 , wherein the base and the lid have the same shape. 
     
     
         7 . The self-venting food storage container of  claim 6 , wherein the base and the lid are circular. 
     
     
         8 . The self-venting food storage container of  claim 6 , wherein the base and the lid are rectangular. 
     
     
         9 . The self-venting food storage container of  claim 1 , wherein the outer surfaces of the container have a grip-enhancing texture. 
     
     
         10 . The self-venting food storage container of  claim 1 , wherein the venting apparatus is bound by a barrier and the barrier has a thickness thicker than the thickness of the lid. 
     
     
         11 . The self-venting food storage container of  claim 1 , wherein the lid and the base are connected by a connecting member and the connecting member has a utensil receptacle configured to store utensils. 
     
     
         12 . The self-venting food storage container of  claim 1 , wherein the connecting member has at least one folding line. 
     
     
         13 . The self-venting food storage container of  claim 1 , wherein the slot of the venting aperture acts as a normally closed pressure relief valve. 
     
     
         14 . The self-venting food storage container of  claim 1 , wherein the slot is shaped as a cross. 
     
     
         15 . The self-venting food storage container of  claim 1 , wherein only one of the arms of the slot is cut through the entire thickness of the venting aperture. 
     
     
         16 . The self-venting food storage container of  claim 1 , wherein the inner surface of the receptacle includes graduated marks. 
     
     
         17 .- 19 . (canceled) 
     
     
         20 . A self-venting food storage container comprising:
 a lid and a base,   wherein the base has at least one sidewall extending from a bottom forming a receptacle for storing food,   wherein the lid is selectively couplable to the base,   wherein the lid has a thickness and a venting aperture, such that the thickness is determined at a location immediately adjacent to the venting aperture,   wherein the entire venting aperture has a thickness thinner than the thickness of the lid and is enclosed by a barrier having a thickness thicker than the thickness of the lid, and
 wherein the venting aperture is made from a pliable material having a slot configured to release pressure-build up in the container. 
   
     
     
         21 . The self-venting food storage container of  claim 20 , wherein the venting aperture is made from silicone. 
     
     
         22 . The self-venting food storage container of  claim 21  wherein the entire lid is made from silicone.
