View Patent ↗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.
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 plastic blister film directly overlying said planar surface of said blister tray and adjacently closing said open ends of said compartment, said blister film having a pair of opposed film surfaces and being resilient and stretchable so as to define said rupture resistance, said blister film including a pattern of rupturable locations extending across said blister film and partially through said film between said film surfaces, at least a portion thereof in overlying registry with said open ends of said blister compartments to render said sheet rupturable at said locations;
said blister compartments being compressible and deformable so as to cause rupturable movement of said products through said blister film;
said rupturable locations are configured from patterns selected from the group consisting of lines, dots, letters, shapes and combinations thereof.
2. A blister package assembly of claim 1 wherein said rupturable locations are formed by perforations placed partially through said blister film.
3. A blister package assembly of claim 1 wherein said rupturable locations are formed by laser cuts placed partially through said film.
4. A blister package assembly of claim 1 wherein said rupturable location extends along said blister film.
5. A blister package assembly of claim 1 wherein said blister film is formed of resilient material.
6. A package assembly of claim 1 wherein said blister film is selected from the group consisting of polyester, polyethylene and combinations thereof.
