Abstract

A blister pack includes a frame defining at least one recessed compartment having an open side defining an opening for containing a product therein. A blister material covers the opening to removably seal the product in the compartment. An opener is supported by the frame over the opening with the opener being moveable to break the blister material and to remove the film to expose the product in the compartment for removal.

Claims

1. A blister pack comprising a frame defining at least one recessed compartment having an open side defining an opening for containing a product therein, a blister material covering said opening to removably seal said product in said compartment, an opener supported by said frame over said opening, said opener being displaceable to pierce said blister material and moveable to cut said blister material to expose said product through said opening, said opener being displaceable downwardly against said blister material to pierce said blister material, said opener being rotatable after piercing said blister material to remove said blister material to expose said product in said compartment, said opener including a first upstanding wall, said opener including at least one extension on the lower surface thereof to pierce and remove said blister material, said opener including at least a second upstanding wall spaced from said first upstanding wall to define a slot therebetween.

2. The blister pack as claimed in claim 1, wherein said opener includes said first upstanding wall on an upper surface thereof to allow said opener to be pressed against said blister material to pierce said blister material and rotated to remove said material.

3. The blister pack as claimed in claim 1, wherein said frame includes a panel overlying said blister material, said panel including at least one opening in alignment with said at least one compartment, said opener being supported by said panel in said panel opening.

4. The blister pack as claimed in claim 3, wherein said panel is formed from a thermoplastic material, said opener being formed with said panel and removeably attached to the sidewall defining said panel opening by integrally formed breakable tabs.

5. A blister pack comprising a frame defining at least one recessed compartment having an open side defining an opening for containing a product therein, a blister material covering said opening to removably seal said product in said compartment, an opener supported by said frame over said opening, said opener being displaceable to pierce said blister material and moveable to cut said blister material to expose said product through said opening, said frame including a panel overlying said blister material, said panel including at least one opening in alignment with said at least one compartment, said opener being supported by said panel in said panel opening, said panel being formed from a thermoplastic material, said opener being formed with said panel and removeably attached to the sidewall defining said panel opening by integrally formed breakable tabs, said panel opening defining a rim, said opener having a body portion larger than said rim, said body portion contacting said rim when displaced downwardly to prevent contact of said opener with said product.

6. The blister pack as claimed in claim 5 wherein said panel includes an integrally formed elongated strap coupling said opener to said panel.

7. The blister pack as claimed in claim 5, wherein said opener includes at least a second extension on the lower surface thereof, said first and second extensions including undercut portions.

8. An opener system for a blister pack, said blister pack including a plurality of compartments each of which includes product therein, and a film material overlying said compartments, the system comprising a panel formed from a thermoplastic material adapted to be secured to said blister pack, said panel including a plurality of openings therein positioned to correspond to the compartments in said blister pack, each opening being defined by a sidewall, an opener positioned in each said opening and removeably coupled to said sidewall, said opener including a piercing device on the lower surface thereof to pierce said film material, said opener being rotatable after piercing of said film material to remove said film material to expose said product in said compartment, said panel being coupleable to said blister pack so that said respective opener can be used to pierce and remove the film material and expose product in a corresponding compartment.

9. The opener system as claimed in claim 8, wherein said opener is coupled to said sidewall by an elongated strap.

10. The opener system as claimed in claim 9, wherein said elongated strap is integrally formed with said panel and opener.

11. The opener system as claimed in claim 10, wherein each said opener is removeably coupled in its respective opening by breakaway tabs.

12. The opener system as claimed in claim 11, wherein said opener includes a flange on the upper surface thereof.

13. The opener system as claimed in claim 11, wherein said opener includes at least one extension on the lower surface thereof, said extension defining a piercer/cutter.

14. The opener system as claimed in claim 13, wherein said opener further includes a second extension defining a piercer/cutter, said first and second including undercuts.

15. The opener system as claimed in claim 8, wherein said opener is circular and includes a coin slot on the upper surface thereof.

16. The opener system as claimed in claim 15, wherein said coin slot is defined by opposing spaced walls each having an extension to allow easy finger purchase.

17. The opener system as claimed in claim 9, wherein said strap permits movement of said opener towards said compartment to pierce said film material and permits rotary movement to remove said film to expose said product in said compartment.
