Abstract

The package supports a plurality of consumable products. The package is a blister package having a plurality of consumable products housed in a blister tray and covered with a rupturable sheet. The sheet overlies the open surfaces of the blister tray and includes rupturable locations formed thereon for permitting passage of the product therethrough.

Claims

1. A blister package assembly for consumable products comprising:

a blister tray having a plurality of open ended blister compartments opening to a common planar surface for supporting said consumable products therein;

a separately formed rupture-resistant resilient plastic blister film overlying said planar surface of said blister tray and closing said open ends of said compartment, said blister film including a plurality of rupturable locations thereon in overlying registry with said open ends of said blister compartments to render said film rupturable at said location;

said plurality of rupturable locations each including an intersecting configuration.

2. A blister package assembly of claim 1 wherein said blister compartments are compressible and deformable so as to cause rupturable movement of said products through said blister film.

3. A blister package assembly of claim 1 wherein said rupturable locations are formed by perforations placed partially through said blister film.

4. A blister package assembly of claim 1 wherein said rupturable locations are formed by laser cuts placed partially through said film.

5. A blister package assembly of claim 1 wherein said rupturable locations form an elongate extent along said blister film.

6. A blister package assembly of claim 5 wherein at least a portion of said elongate extent overlies said open ends of said blister compartments.

7. A blister package assembly of claim 5 wherein said elongate extent is curved.

8. A blister package assembly of claim 5 wherein said elongate extent is wavy.

9. A blister package assembly of claim 5 wherein said elongate extent is angular.

10. A blister package assembly of claim 5 wherein said rupturable locations form a plurality of elongate extents.

11. A blister package assembly of claim 10 wherein said elongate extents extend in parallel.

12. A package assembly of claim 1 wherein said plastic film is selected from the group consisting of polyester, polyethylene and combinations thereof.

13. A blister package assembly for consumable products comprising:

a blister tray having a plurality of open ended blister compartments opening to a common planar surface for supporting said consumable products therein;

a separately formed rupture-resistant resilient plastic blister film overlying said planar surface of said blister tray and closing said open ends of said compartment, said blister film including a plurality of rupturable locations thereon in overlying registry with said open ends of said blister compartments to render said film rupturable at said location;

wherein a rupturable location overlying at least one of said blister compartments includes a curve.

14. A blister package assembly for consumable products comprising:

a blister tray having a plurality of open ended blister compartments opening to a common planar surface for supporting said consumable products therein;

a separately formed rupture-resistant resilient plastic blister film overlying said planar surface of said blister tray and closing said open ends of said compartment, said blister film including a plurality of rupturable locations thereon in overlying registry with said open ends of said blister compartments to render said film rupturable at said location;

wherein a rupturable location overlying said blister components includes an angle.
