Method and article for packaging dosed products

Abstract

The present invention provides a child-resistant package for a dosed-form product having a blister layer, a rupturable layer disposed adjacent the blister layer, the rupturable layer and the blister layer together defining at least one cavity, a diaphragm layer for resisting passage of a dose, the diaphragm layer disposed adjacent the rupturable layer on a side of the rupturable layer opposite the blister layer, and a backing layer having at least one moveable tab corresponding to the at least one cavity, the backing layer disposed adjacent the diaphragm layer on a side of the diaphragm layer opposite the rupturable layer. Also included are methods of packaging dosed products in accordance with the invention.

         2 . The child-resistant package of  claim 1  wherein said means for resisting is a diaphragm layer having a slit disposed therein.  
     
     
         3 . The child-resistant package of  claim 1  wherein said means for resisting is comprised of plastic.  
     
     
         4 . The child-resistant package of  claim 1  wherein said backing layer comprises paper.  
     
     
         5 . The child-resistant package of  claim 1  wherein said rupturable layer comprises foil.  
     
     
         6 . The child-resistant package of  claim 1  wherein said backing layer comprises plastic.  
     
     
         7 . The child-resistant package of  claim 1  wherein said means for resisting is a diaphragm layer formed of a non-woven barrier material.  
     
     
         8 . The child-resistant package of  claim 1  wherein said backing layer is formed of a non-woven barrier material.  
     
     
         9 . The child-resistant package of  claim 1  where said rupturable layer is formed of a woven barrier material.  
     
     
         10 . A child-resistant package for a product comprising: 
 a blister layer;    a rupturable layer disposed adjacent the blister layer, said rupturable layer and said blister layer together defining at least one cavity;    a diaphragm layer having at least one slit corresponding to the at least one cavity in said blister layer, said diaphragm layer disposed adjacent said rupturable layer on a side of said rupturable layer opposite said blister layer; and    a backing layer having at least one moveable tab corresponding to the at least one slit in said diaphragm layer, said backing layer disposed adjacent said diaphragm layer on a side of said diaphragm layer opposite said rupturable layer.    
     
     
         11 . The child-resistant package of  claim 10  wherein said diaphragm layer comprises paper.  
     
     
         12 . The child-resistant package of  claim 10  wherein said backing layer comprises paper.  
     
     
         13 . The child-resistant package of  claim 10  wherein said diaphragm layer comprises plastic.  
     
     
         14 . The child-resistant package of  claim 10  wherein said rupturable layer comprises foil.  
     
     
         15 . The child-resistant package of  claim 10  wherein said backing layer is plastic.  
     
     
         16 . The child-resistant package of  claim 10  wherein said diaphragm layer is formed of a non-woven barrier material.  
     
     
         17 . The child-resistant package of  claim 10  wherein said diaphragm layer is formed of a woven barrier material.  
     
     
         18 . The child-resistant package of  claim 10  wherein said backing layer is formed of a non-woven barrier material.  
     
     
         19 . A method for forming a child-resistant package for a product, said method comprising the steps of: 
 (a) placing a product in a cavity formed in a blister cover;    (b) disposing a barrier adjacent the blister cover, thereby containing the product between the blister cover and the barrier;    (c) disposing a diaphragm layer adjacent the barrier layer, said diaphragm layer having at least one slit corresponding to the at least one cavity; and    (d) disposing a backing layer adjacent the diaphragm layer, said backing layer having at least one peel-away tab corresponding to the at least one slit of the diaphragm layer.    
     
     
         20 . The method of  claim 19  wherein step (b) comprises disposing a foil layer adjacent the blister cover.  
     
     
         21 . The method of  claim 19  wherein step (c) comprises disposing a plastic layer adjacent the barrier layer.  
     
     
         22 . The method of  claim 19  wherein the backing is formed from any one or more of film, plastic, non-woven barrier material, woven barrier material or paper.  
     
     
         23 . A method of packaging a dosed product comprising the steps of: 
 (a) sealing a plurality dosages between a foil layer and a blister layer;    (b) adhering a diaphragm layer to the foil layer such that slits in the diaphragm correspond to dosages sealed between the foil and blister layers; and    (c) adhering a backing layer to the diaphragm layer such that a moveable tab in the backing layer corresponds to each slit in the diaphragm layer.
