Child Resistant Blister Packaging and a Method of Removing The Contents Therefrom

Abstract

A child resistant blister packaging having an upper cover sheet with at least one aperture, a bottom backing card with at least one scored exit port, and a blister laminate situated between the cover sheet and the backing card, the blister laminate includes at least one blister containing a cavity for receiving a pill and a foil layer adhered to the a bottom surface of the sheet. The blister protrudes through the aperture in the cover sheet and is arranged on a carrier tab that will not line up in registry with the scored exit port in the backing card. Upon the application of sufficient force, the blister can be moved to align the pill-receiving cavity with the scored exit port and the blister can be collapsed to force a medicament stored in the cavity through the foil layer and the scored exit port.

1 . A child-resistant blister packaging comprising:
 a cover sheet having at least one aperture, said aperture having a first end and a second end,   a backing card having at least one exit port, and   a blister laminate arranged between said cover sheet and said backing card, wherein said exit port is in registry with said second end of said aperture, said blister laminate comprising a blister sheet and a rupturable layer, wherein said blister sheet has a top surface and a bottom surface, said top surface having at least one blister containing a pill-receiving cavity integrally formed therein and projecting from said top surface and through said first end of said aperture, and said bottom surface is a rupturable layer laminated onto said top surface of said blister sheet, said rupturable layer extending over and sealingly closing said pill-receiving cavity,   said blister laminate further comprising at least one carrier tab, at least one separable connection means, and at least one gap adjacent to said carrier tab, and said carrier tab having a perimeter wherein said blister resides within said perimeter,   wherein said carrier tab is held stationary by said at least one separable connection means, and upon severing said at least one separable connection means, said carrier tab is movable and said blister is guided by said aperture from said first end of said aperture to said second end of said aperture to align in registry with said exit port.   
   
   
       2 . The child-resistant blister packaging of  claim 1 , wherein the child resistant blister packaging has a plurality of blisters, a plurality of apertures, and a plurality of exit ports. 
   
   
       3 . The child-resistant blister packaging of  claim 1 , further comprising a ridge along a periphery of said gap, wherein said aperture is in alignment with said exit port when said carrier tab engages said ridge of said gap. 
   
   
       4 . The child-resistant blister packaging of  claim 3 , wherein an elevated rib runs parallel and adjacent to said ridge of said gap. 
   
   
       5 . The child-resistant blister packaging of  claim 1 , wherein said cover sheet and said backing card are made of substantially rigid materials. 
   
   
       6 . The child-resistant blister packaging of  claim 1 , wherein said blister has a lateral protrusion to accommodate the tip of a finger or thumb. 
   
   
       7 . The child-resistant blister packaging of  claim 1 , wherein said aperture has an arcuate shape. 
   
   
       8 . The child-resistant blister packaging of  claim 1 , wherein said aperture comprises means for guiding movement of said blister from said first end of said aperture to said second end of said aperture along an arcuate path. 
   
   
       9 . The child-resistant blister packaging of  claim 1 , wherein said exit port is a scored area in said backing card. 
   
   
       10 . The child-resistant blister packaging of  claim 1 , wherein said carrier tab and said exit port are generally square shaped. 
   
   
       11 . The child-resistant blister packaging of  claim 1 , wherein said blister is approximately centered on said carrier tab. 
   
   
       12 . The child-resistant blister packaging of  claim 1 , wherein said connection means is integrally connected to said carrer tab and said blister laminate. 
   
   
       13 . The child-resistant blister packaging of  claim 1 , wherein said connection means is at least one short, thin strip of said blister laminate. 
   
   
       14 . A method of extracting a medicament from a pill-receiving cavity in a child resistant blister packaging comprising the steps of:
 exerting pressure on a side wall of a blister containing a pill-receiving cavity protruding through a first end of an aperture in the child resistant blister packaging, wherein the pill-receiving cavity is arranged on a carrier tab that is connected to a separable connection means and said carrier tab is adjacent to a gap,   separating said connection means so that said carrier tab is movable,   guiding said blister to a second end of said aperture until said carrier tab is at the second end of the aperture,   aligning said pill-receiving cavity with an exit port in a bottom sheet of the child resistant blister packaging, and   collapsing a top surface of the blister to push the medicament stored in said pill-receiving cavity through said exit port.
