Blister package

Abstract

A child-resistant package for a product is provided. The package comprises a double cover comprised of separate outer and inner layers, wherein the outer layer is disposed adjacent the inner layer, and a barrier disposed adjacent the inner layer of the double cover, wherein the inner layer and the barrier together define at least one compartment into which a product can be positioned. Also included are embodiments where the cover is a single layer and the bottom barrier is a double layer, and where both the cover and barrier are multiple layers. Included in the invention is a method of making a child-resistant package consistent with the package of the invention.

         3 . The package of  claim 1  wherein at least one of the inner and outer layers of the double cover is formed from a film.  
     
     
         4 . The package of  claim 3  wherein the film is translucent.  
     
     
         5 . The package of  claim 1  wherein at least one of the inner and outer layers of the double cover is formed from a foil.  
     
     
         6 . The package of  claim 1  wherein the outer layer of the double cover is formed from a film and the inner layer of the double cover is formed from a foil.  
     
     
         7 . The package of  claim 1  wherein each of the outer and inner layers defines at least one blister cavity integrally formed therein and projecting from one side thereof, together forming a double blister cover.  
     
     
         8 . The package of  claim 7  wherein each of the outer and inner layers of the double cover is formed from a film.  
     
     
         9 . The package of  claim 1  wherein the barrier is comprised of at least two separate layers.  
     
     
         10 . The package of  claim 9  wherein the barrier is formed from any one or more of foil, film, plastic, or paper.  
     
     
         11 . The package of  claim 10  wherein the barrier has a frangible section overlying each compartment, the frangible section being defined by a perforated or scored line in the barrier.  
     
     
         12 . A method for forming a child-resistant package for a product, said method comprising the steps of: 
 (a) forming a double cover by disposing an outer layer adjacent an inner layer, the double cover defining at least one cavity;    (b) placing a product in the cavity of the double cover; and    (c) disposing a barrier adjacent the inner layer of the double cover, thereby defining at least one compartment between the inner layer of the double cover and the barrier in which the product is contained.    
     
     
         13 . The method of  claim 12  wherein the forming step comprises forming at least one blister cavity in at least one of the inner and outer layers of the double cover.  
     
     
         14 . The method of  claim 12  wherein the forming step comprises disposing a film adjacent a foil.  
     
     
         15 . The method of  claim 12  wherein the forming step comprises disposing a film adjacent a film.  
     
     
         16 . The method of  claim 12  wherein the disposing step comprises laminating a foil to the side of the inner layer opposite the outer layer.  
     
     
         17 . The method of  claim 16  wherein the disposing step further comprises disposing a backing adjacent the foil opposite the inner layer of the double cover.  
     
     
         18 . The method of  claim 7  wherein the backing is formed from any one or more of film, plastic, paper, or foil.  
     
     
         19 . The method of  claim 17  further comprising defining a frangible section in the backing overlying each cavity.  
     
     
         20 . A child-resistant package for a product comprising: 
 a cover; and    a double barrier disposed adjacent the cover, said double barrier comprising separate outer and inner layers, wherein the outer layer is disposed adjacent the inner layer;    wherein the inner layer of the double barrier and the cover together define at least one compartment into which a product can be positioned.    
     
     
         21 . The package of  claim 20  wherein the inner layer of the double barrier is formed from any one or more of foil, film, plastic or paper.  
     
     
         22 . The package of  claim 20  wherein the outer layer of the double barrier is formed from any one or more of foil, film, plastic or paper, or combinations thereof.  
     
     
         23 . The package of  claim 20  wherein the inner layer of the double barrier is formed from any one or more of foil, film, plastic, or paper, or combinations thereof.  
     
     
         24 . The package of  claim 20  wherein the inner layer of the double barrier is a foil and paper laminate.  
     
     
         25 . The package of  claim 20  wherein the inner layer of the double barrier is accessible only after at least partial removal of the outer layer of the double barrier.  
     
     
         26 . The package of  claim 20  wherein the cover is a double cover comprised of separate outer and inner layers, wherein the outer layer is disposed adjacent the inner layer.  
     
     
         27 . A method for forming a child-resistant package for a product, said method comprising the steps of: 
 (a) forming a double barrier by disposing an outer layer adjacent an inner layer;    (b) placing a product in a cavity of a cover; and    (c) disposing the cover adjacent the inner layer of the double barrier, thereby defining at least one compartment between the inner layer of the double barrier and the cover in which the product is contained.
