Reusable Food Wrap and Bag

Abstract

A reusable flexible sheet is disclosed. The flexible sheet includes a central layer that can assume a manipulated shape. The central conformable layer is encased within a first sheet on one side, and a second sheet on the opposite side. The three layers move in unison. The outer first sheet and second sheet are generally impermeable to liquids and solids, and allow the flexible sheet to be cleaned and reused. In some cases, the flexible sheet material can be folded or formed into a storage bag. Various methods of making the reusable flexible sheet are also disclosed.

What is claimed is: 
     
         1 . A flexible sheet, comprising:
 a central layer, a first sheet and a second sheet, wherein the central layer is disposed between the first sheet and the second sheet;   the central layer being more rigid than the first sheet, the central layer being more rigid than the second sheet;   the central layer being more plastically deformable than the first sheet, the central layer being more plastically deformable than the second sheet;   wherein the first sheet, the central layer and the second sheet are joined together so that they all deflect in unison.   
     
     
         2 . The flexible sheet according to  claim 1 , wherein the central layer retains a manipulated configuration, and wherein the first sheet attains a first configuration that corresponds to the manipulated configuration of the central layer, and wherein second sheet attains a second configuration that corresponds to the manipulated configuration of the central layer. 
     
     
         3 . The flexible sheet according to  claim 1 , wherein the central layer is made of a material that includes a metal. 
     
     
         4 . The flexible sheet according to  claim 1 , wherein the first sheet is made of a material including a polymer, and wherein the second sheet is made of the same material as the first sheet. 
     
     
         5 . The flexible sheet according to  claim 1 , wherein the first sheet is less permeable than the central layer. 
     
     
         6 . The flexible sheet according to  claim 1 , wherein the flexible sheet may be returned to an original configuration after being plastically deformed. 
     
     
         7 . A flexible sheet, comprising:
 a central layer, a first sheet and a second sheet, wherein the central layer is disposed between the first sheet and the second sheet;   the central layer being made of a material that can retain its shape better than the first layer, the central layer also being capable of retaining its shape better than the second sheet;   the first sheet being less permeable than the central layer, the second sheet also being less permeable than the central layer;   wherein the first sheet and the second sheet encase the central layer and prevent foreign objects from contacting the central layer.   
     
     
         8 . The flexible sheet according to  claim 7 , wherein the central layer is more plastically deformable than the first sheet, and wherein the central layer is more plastically deformable than the second sheet. 
     
     
         9 . The flexible sheet according to  claim 7 , wherein the central layer is made of a material that includes a metal. 
     
     
         10 . The flexible sheet according to  claim 7 , wherein the first sheet is made of a material including a polymer, and wherein the second sheet is made of the same material as the first sheet. 
     
     
         11 . The flexible sheet according to  claim 7 , further comprising a first intermediate sheet disposed between the central layer and the first sheet, the first intermediate sheet being made of a material different than the central layer, and the first intermediate sheet being made of a material different than the first sheet. 
     
     
         12 . The flexible sheet according to  claim 11 , further comprising a second intermediate sheet disposed between the central layer and the second sheet, the second intermediate sheet being made of a material different than the central layer, and the second intermediate sheet being made of a material different than the second sheet. 
     
     
         13 . The flexible sheet according to  claim 12 , wherein the central layer is attached to the first sheet and wherein the central layer is attached to the second sheet, and wherein the first sheet, the central layer and the second sheet all move in unison with one another. 
     
     
         14 . The flexible sheet according to  claim 7 , wherein the flexible sheet can be shaped into a self-standing structure. 
     
     
         15 . A method of making a flexible sheet, comprising:
 aligning a central layer between a first sheet and a second sheet;   placing the central layer, the first sheet and the second sheet in a compression mold;   sealing a first perimeter of the first sheet with a second perimeter of the second sheet;   
       wherein the central layer is more rigid than the first sheet and the central layer is more rigid than the second sheet; and 
       wherein the central layer is more plastically deformable than the first sheet and the central layer is more plastically deformable than the second sheet. 
     
     
         16 . The method according to  claim 15 , wherein the step of sealing further includes placing a rubber cord around the first perimeter and the second perimeter. 
     
     
         17 . The method according to  claim 15 , wherein the central layer, the first sheet and the second sheet are die cut into a predetermined shape prior to sealing the first perimeter of the first sheet with the second perimeter of the second sheet. 
     
     
         18 . The method according to  claim 15 , wherein a cloth layer is placed between the first sheet and the central layer during the step of alignment. 
     
     
         19 . The method according to  claim 15 , wherein the method includes inserting the first sheet, the second sheet and the central layer through a set of rollers to press the first sheet, the second sheet and the central layer together. 
     
     
         20 . The method according to  claim 15 , wherein the central layer is smaller than the first sheet, wherein the central layer is smaller than the second sheet and wherein a perimeter of the central layer is disposed inwardly of the first perimeter and the second perimeter. 
     
     
         21 . The method according to  claim 15 , wherein the central layer is a layer of glass cloth with metal wire woven through the glass cloth.
