Blister pack

Abstract

A blister pack ( 1 ) with a base part ( 2 ) with at least one depression ( 3 ) that is surrounded by a shoulder, the entirety of shoulders forming a contiguous surface. A cover film ( 5 ) is sealed onto the base part ( 2 ) and covers the openings ( 4 ) of the depressions. The base part ( 2 ) is provided with arrangement ( 9 ) that facilitate the opening of the pack. The arrangement is configured as one or more flat parts that are defined by separating lines ( 7 ), preferably in the form of indentations ( 10 ). The indentations can be bent along the separating lines ( 7 ) at least partially outwards from the base part ( 2 ). At least one edge or tip so that, with the help of the bent flat part ( 10 ), the cover film ( 5+L) positioned above the opening ( 4 ) of the depression can be undone, perforated, broken or weakened to such an extent that the product contained therein can be forced through the depression ( 3 ) by hand. A rolling up element can be joined to the edge portion as part of the opening aid ( 9 ′″)

         5 . Blister pack according to  claim 3 , characterised in that the surface parts  35  ( 10 ) of the opening aid ( 9 ) can be pressed out from the base part ( 2 ) or the surface element ( 6 ) by hand or with an aid, or that by folding the surface element ( 6 ) to the convex side of the assigned recess ( 3 ), the recess ( 3 ) comes to lie on the opening aid ( 9 ) and the surface part(s) ( 10 ) of the opening aid ( 9 ) can be pressed out of the surface element ( 6 ) by means of the recesses, and that by folding the surface element ( 6 ) to the concave side, the opening aid ( 9 ) comes to lie on the cover film ( 5 ) in the area of the recess opening ( 4 ).  
     
     
         6 . Blister pack according to  claim 1 , characterised in that the opening aid ( 9 ) is formed in the shape of one or several points or teeth ( 10 ), whereby the points or teeth are outlined by weakening lines ( 8 ′) and are preferably circular or polygonal arranged, and the tips of the points or teeth are preferably arranged at a common point in the surface element ( 6 ), and in that preferably a fold line ( 7 ′) is arranged between the two adjacent tips of weakening lines ( 8 ′) to form a toothed or pointed crown when the points or teeth are pushed out from the base part ( 2 ).  
     
     
         7 . Blister pack according to  claim 4 , characterised in that to each recess ( 3 ) is assigned a surface element ( 6 ) with an opening aid ( 9 ), and the surface elements ( 6 ) are arranged mutually offset and opposite between the recesses ( 3 ) or at the sides in lines.  
     
     
         8 .
