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 comprising:

a blister tray having a plurality of spaced open ended blister compartments opening to a common planar surface;

a plurality of consumable products, each of said blister compartments containing one of said plurality of consumable products; and

a separately formed resilient single layer plastic blister film directly overlying said planar surface of said blister tray and adjacently closing said open ends of said compartment, said blister film including a pattern of rupturable locations extending across and partially through said blister film overlying said planar surface, at least portions of said rupturable locations being in overlying registry with said open ends of said blister compartments so as to permit rupturable puncturing of said blister film at said location of said overlying registry to permit dispensing of said product through said location.

2. A blister package assembly of claim 1 wherein said blister compartments are compressible and deformable.

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

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

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

6. A package assembly of claim 1 wherein said rupturable locations are formed by mechanical cuts.

7. A package assembly of claim 1 wherein said rupturable locations are identically configured.

8. A package assembly of claim 1 wherein said rupturable locations are differently configured.

9. A package assembly of claim 1 wherein said rupturable locations are symmetrically positioned over each open surface of said compartments.

10. A package assembly of claim 1 wherein said rupturable locations are asymmetrically positioned over each open surface of said compartments.

11. A package assembly of claim 1 wherein said rupturable locations include a plurality of lines extending across said blister film.

12. A package assembly of claim 11 wherein said lines are spaced apart and parallel.

13. A package assembly of claim 11 wherein said lines are non-parallel.

14. A package assembly of claim 11 wherein said lines are non-equally spaced apart transversely across said blister film.

15. A package assembly of claim 1 wherein said rupturable locations extend entirely across said blister film.

16. A package assembly of claim 1 wherein said rupturable locations include a curved pattern in overlying registry with said open end compartments.

17. A blister package assembly comprising:

a blister tray having a plurality of spaced open ended blister compartments opening to a common planar surface said blister compartments arranged in spaced apart longitudinal columns and transverse rows;

a plurality of consumable products, each of said blister compartments containing one of said plurality of consumable products; and

a separately formed single layer 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 pattern of elongate rupturable locations extending partially through said blister film and in overlying registry with said open ends of said blister compartments along said columns without overlying said surface between said longitudinal columns so as to permit rupturable puncturing of said blister film at said location of said overlying registry to permit dispensing of said product through said location.

18. A package assembly of claim 17 wherein said rupturable locations include a plurality of lines extending over said columns of blister compartment.

19. A package assembly of claim 18 wherein said lines are spaced apart and parallel.

20. A package assembly of claim 18 wherein said lines are non-equally spaced apart.
