Child Resistant Package

Abstract

A child resistant drug package. The package includes a blister layer having at least one blister and a plurality of backing layers covering the blister layer. The backing layers include tabs that require sequential removal in order to gain access to the contents of the blister.

1 . A child resistant package, comprising:
 a blister layer having a top surface, a bottom surface and at least one blister, wherein said blister extends from said top surface;   an inner backing layer having a top surface, a bottom surface and at least one access tab disposed adjacent to said blister, wherein said top surface of said inner backing layer is coupled to said bottom surface of said blister layer; and   an outer backing layer having a top surface, at least one cover tab and at least one lock tab, wherein said top surface of said outer backing layer is coupled to said bottom surface of said inner backing layer,   wherein said cover tab is disposed adjacent to said access tab and said lock tab is disposed adjacent to said cover tab.   
     
     
         2 . The child resistant package of  claim 1 , wherein said top surface of said inner backing layer is directly coupled to said bottom surface of said blister layer. 
     
     
         3 . The child resistant package of  claim 1 , further comprising:
 a rupturable lidding layer having a top surface and a bottom surface, wherein said top surface of said inner backing layer is coupled to said bottom surface of said blister layer via said lidding layer.   
     
     
         4 . The child resistant package of  claim 3 , wherein said lidding layer is foil. 
     
     
         5 . The child resistant package of  claim 1 , wherein said outer backing layer includes an access hole corresponding to said lock tab. 
     
     
         6 . The child resistant package of  claim 1 , wherein said cover tabs and said lock tabs are defined by perforations in said outer backing layer. 
     
     
         7 . The child resistant package of  claim 1 , further comprising:
 a cover layer having a bottom surface and an aperture corresponding to said blister, wherein said bottom surface of said cover layer is coupled to said top surface of said blister layer such that said blister extends through said aperture.   
     
     
         8 . The child resistant package of  claim 1 , wherein said blister layer has a plurality of blisters. 
     
     
         9 . A child resistant package, comprising:
 a blister layer including a blister;   a lidding layer coupled to said blister layer; and   a backing layer coupled to said lidding layer that includes a first access system disposed adjacent to said blister and a second multi-step access system disposed adjacent to said first access system,   wherein said second access system is configured to communicate with said first access system such that said first access system is accessible via said second access system.   
     
     
         10 . The child resistant package of  claim 9 , wherein said backing layer includes an inner backing layer coupled to said lidding layer and an outer backing layer coupled to said inner backing layer, and wherein said first access system is disposed on said inner backing layer and said second access system is disposed on said outer backing layer. 
     
     
         11 . The child resistant package of  claim 9 , wherein said first access system includes an access tab and an access hole. 
     
     
         12 . The child resistant package of  claim 9 , wherein said second access system includes a lock tab, a cover tab and an access hole. 
     
     
         13 . A child resistant package, comprising:
 a blister layer including a blister;   an inner backing layer coupled to said blister layer and having a first access system disposed adjacent to said blister; and   an outer backing layer coupled to said inner backing layer and having a second access system that includes multiple sequential peel tabs, is disposed adjacent to said first access system, and is configured to communicate with said first access system such that said first access system is accessible via said second access system.   
     
     
         14 . The child resistant package of  claim 13 , wherein said first access system includes an access tab and an access hole. 
     
     
         15 . The child resistant package of  claim 13 , wherein said second access system includes a lock tab, a cover tab and an access hole.
