Lids for the Preserving of Materials

Abstract

Lids for preserving materials in accordance with various embodiments of the invention are disclosed. In one embodiment, a preservation lid for preserving materials stored within a container is provided, the preservation lid comprising: a top disk comprising a first face and a second face; a handle that is affixed to the second face of the top disk; a bottom disk that is affixed to the first face of the top disk, wherein the bottom disk comprises a skirt having a threshold force for deformation; wherein internal air escapes from the container when a pressure inside of the container exceeds the threshold force of the skirt.

What is claimed is: 
     
         1 . A preservation lid for preserving materials stored within a container, the preservation lid comprising:
 a top disk comprising a first face and a second face;   a handle that is affixed to the second face of the top disk;   a bottom disk that is affixed to the first face of the top disk, wherein the bottom disk comprises a skirt having a threshold force for deformation;   wherein internal air escapes from the container when a pressure inside of the container exceeds the threshold force of the skirt.   
     
     
         2 . The preservation lid of  claim 1 , wherein the pressure inside of the container increases when the preservation lid is pressed into the container. 
     
     
         3 . The preservation lid of  claim 1 , wherein a diameter of the top disk is smaller than a diameter of the bottom disk. 
     
     
         4 . The preservation lid of  claim 1 , wherein the bottom disk and the skirt are one continuous piece. 
     
     
         5 . The preservation lid of  claim 1 , wherein the skirt comprises at least one cut. 
     
     
         6 . The preservation lid of  claim 1 , wherein the skirt comprises a plurality of radial, equidistant cuts around a circumference of the skirt. 
     
     
         7 . The preservation lid of  claim 6 , wherein the skirt overlaps itself at the radial, equidistant cuts when the preservation lid is pressed into the container. 
     
     
         8 . The preservation lid of  claim 1 , wherein the skirt comprises at least one pleat. 
     
     
         9 . The preservation lid of  claim 1 , wherein the skirt comprises a plurality of radial, equidistant folds around the circumference of the skirt. 
     
     
         10 . The preservation lid of  claim 1 , wherein the skirt bends when the pressure inside of the container exceeds the threshold force. 
     
     
         11 . The preservation lid of  claim 10 , wherein the skirt bends up to 90 degrees relative to the top disk. 
     
     
         12 . The preservation lid of  claim 1 , wherein the skirt is in contact with an inner surface of the container preventing internal air from escaping the container when the internal pressure is below the threshold force of the skirt. 
     
     
         13 . The preservation lid of  claim 1 , wherein the skirt releases internal air from the container when a user applies a downward force on the preservation lid. 
     
     
         14 . The preservation lid of  claim 13 , wherein the skirt folds upwards when the user applies the downward force on the preservation lid. 
     
     
         15 . The preservation lid of  claim 1 , wherein the top disk is rigid and nonporous. 
     
     
         16 . The preservation lid of  claim 1 , wherein the skirt allows external air to be sucked into the container when a user applies an upward force on the preservation lid. 
     
     
         17 . The preservation lid of  claim 1 , wherein the skirt is made using a material selected from a group consisting of rubber, synthetic rubber, silicone, and plastic. 
     
     
         18 . The preservation lid of  claim 1 , wherein the preservation lid and the container include in an open configuration allowing access to the materials stored in the container. 
     
     
         19 . The preservation lid of  claim 1 , wherein the preservation lid and the container include a closed configuration where the preservation lid closes the container. 
     
     
         20 . The preservation lid of  claim 1 , wherein the preservation lid and the container include a preservation configuration where internal air is removed from within the container.
