Abstract

A package ( 100 ) is disclosed which includes a blister with two halves ( 150,160 ) that rotate apart, the blister flanges being sealed within two paperboard cards ( 110, 120 ). The package may be opened by tearing across the paperboard cards, then rotating or tilting the blister halves apart.

First claim

The invention claimed is:

1. A packaging structure comprising:
a blister comprising a first portion and a second portion, the portions being separate pieces;
a front card comprised of sheet material and having edges;
a back card comprised of sheet material and having edges;
at least one of the front card and back card comprising
an opening to receive a front or back part of the blister, and
a perforation line extending at least partly from one of said edges to a point along said opening;

wherein the first portion is formed of two or more pieces of material each having a flange, the flanges being brought together in facing relationship to form the first portion.

2. The package of claim 1 , in which the first portion is held a fixed position relative to the second portion when the perforation line is intact, and the first portion is movable relative to the second portion after the perforation line is severed.

3. The package of claim 1 , in which the first portion is formed of a single piece of material folded about a crease line.

4. The package of claim 1 , in which the second portion is formed of a single piece of material folded about a crease line.

5. The package of claim 1 , in which the second portion is formed of two or more pieces of material each having a flange, the flanges being brought together in facing relationship to form the second portion.

6. The package of claim 1 , wherein the blister comprises at least one flange positioned between the front and back cards.

7. The package of claim 1 , wherein the front and back cards are sealed together.

8. The package of claim 1 , having a non-interference fit between the first blister portion and the second blister portion.

9. The package of claim 1 , having a bayonet connection between the first blister portion and the second blister portion.

10. The package of claim 1 , having a screw connection between the first blister portion and the second blister portion.

11. The package of claim 1 , having a snap fit connection between the first blister portion and the second blister portion.

12. The package of claim 1 , wherein the perforation line must be torn before the first blister portion can be moved relative to the second blister portion.

13. The package of claim 2 , wherein the moving apart comprises a rotation of the first portion relative to the second portion.

14. The package of claim 2 , wherein the moving apart comprises a tilting movement of the first portion relative to the second portion.

15. The package of claim 1 , wherein the perforation line is broken by tearing from one of said edges.

16. The package of claim 1 , wherein the perforation line is broken by flexing or bending along the perforation line.

17. A packaging structure comprising:
a blister comprising a first portion and a second portion, the portions being separate pieces;
a front card comprised of sheet material and having edges;
a back card comprised of sheet material and having edges;
at least one of the front card and back card comprising
an opening to receive a front or back part of the blister, and
a perforation line extending at least partly from one of said edges to a point along said opening,

wherein the first portion is held a fixed position relative to the second portion when the perforation line is intact, and the first portion is movable relative to the second portion after the perforation line is severed, and
wherein the moving apart comprises a rotation of the first portion relative to the second portion.

18. A packaging structure comprising:
a blister comprising a first portion and a second portion, the portions being separate pieces;
a front card comprised of sheet material and having edges;
a back card comprised of sheet material and having edges;
at least one of the front card and back card comprising
an opening to receive a front or back part of the blister, and
a perforation line extending at least partly from one of said edges to a point along said opening,

wherein the first portion is held a fixed position relative to the second portion when the perforation line is intact, and the first portion is movable relative to the second portion after the perforation line is severed, and
wherein the moving apart comprises a tilting movement of the first portion relative to the second portion.
