Packaging Device and Method for Absorbing Moisture

Abstract

A packaging device and method for absorbing and reducing moisture as well as a manufacturing process for such device. The packaging device is a container made from paperboard such as containerboards or linerboards with a corrugated medium. The paperboard is insulated with moisture absorbing additives comprising charcoal, activated charcoal, activated carbon, or substances mostly comprised of carbon. Perforations may be added in the boards to further permit moisture to reach the corrugated medium, permitting further absorption by the additives embedded within the corrugated medium in between the boards. This packaging device and method is favorable for storing or transporting objects which are sensitive to or would benefit from low moisture/humidity conditions.

1 . A boxboard container comprising:
 a moisture absorbent layer for absorbing moisture of an item contained within the boxboard container;   an inner layer for separating the item contained within the boxboard container from the moister absorbent layer; and   an outer layer more resistant to the flow of air than the inner liner board sheet.   
     
     
         2 . The boxboard container of  claim 1 , wherein the inner layer has perforations formed thereon. 
     
     
         3 . The boxboard container of clam  1 , wherein the moisture absorbent layer is a corrugated sheet. 
     
     
         4 . The boxboard container of clam  1 , wherein the moisture absorbent layer comprises activated carbon or charcoal. 
     
     
         5 . The boxboard container of  claim 1 , wherein the outer layer defines an exterior of the boxboard container and the inner layer defines an interior of the boxboard. 
     
     
         6 . The boxboard container of  claim 1 , wherein the moisture absorbent layer is coated with activated carbon using of one of a paper making machine or an off-machine coating technique. 
     
     
         7 . The boxboard container of  claim 1 , wherein the moisture absorbent layer is coated with activated carbon using a bath coating technique. 
     
     
         8 . The boxboard container of  claim 1 , wherein the moisture absorbent layer is coated with activated carbon using a surface sizing coating technique. 
     
     
         9 . The boxboard container of  claim 1 , wherein activated carbon is embedded in the moisture absorbent layer by mixing pulp, water and activated carbon. 
     
     
         10 . A food container comprising:
 a moisture absorbent layer for absorbing moisture emanating from an article of food contained within the food container;   an inner layer for separating the article of food from the moister absorbent layer; and   an outer layer more resistant to the flow of air than the inner layer.   
     
     
         11 . The food container of  claim 10 , wherein the inner layer has perforations formed thereon. 
     
     
         12 . The food container of  claim 10 , wherein the moisture absorbent layer is a corrugated sheet. 
     
     
         13 . The food container of  claim 10 , wherein the moisture absorbent layer comprises activated carbon or charcoal. 
     
     
         14 . The food container of  claim 10 , wherein the outer layer defines an exterior of the food container and the inner layer defines an interior of the food container. 
     
     
         15 . The food container of  claim 10 , wherein the moisture absorbent layer is coated with activated carbon using of one of a paper making machine or an off-machine coating technique. 
     
     
         16 . The food container of  claim 10 , wherein the moisture absorbent layer is coated is with activated carbon using a bath coating technique. 
     
     
         17 . The food container of  claim 10 , wherein the moisture absorbent layer is coated with activated carbon using a surface sizing coating technique. 
     
     
         18 . The food container of  claim 10 , wherein activated carbon is embedded in the moisture absorbent layer by mixing pulp, water and activated carbon. 
     
     
         19 . A boxboard container comprising:
 a corrugated moisture absorbent layer for absorbing moisture of an item contained within the boxboard container;   a perforated inner layer for separating the item contained within the boxboard container from the moister absorbent layer; and   an outer layer more resistant to the flow of air than the inner liner board sheet.   
     
     
         20 . The boxboard container of  claim 19 , wherein the corrugated moisture absorbent layer comprises activated carbon or charcoal.
