Abstract

A package is disclosed comprising an outer blister portion and an inner blister portion, each blister portion having a flange, the flanges enclosed between paperboard cards, arranged so that upon rotation of the outer blister portion access is obtained to compartments within the inner blister portion. The compartments may hold product items.

First claim

The invention claimed is:

1. A package comprising:
a first card and a second card comprised of sheet material, the first and second cards at least partly attached together to form a two-ply structure;
an inner blister comprising an inner body portion and an inner blister flange, the inner body portion defining at least one compartment;
an outer blister comprising an outer body portion and an outer blister flange; the outer body portion fitting over the inner body portion, the outer body portion including an opening; and
an aperture in the first card to receive both blister body portions with both flanges positioned between the first and second cards and the inner blister flange attached to one or both of the cards;
wherein the outer blister flange is able to rotate in the aperture only after breaking a temporary attachment to at least one of the first card, second card, or inner blister flange;

wherein the temporary attachment is a lock tab extending radially outward from the outer blister flange, the lock tab being attached to at least one of the first card, second card, or inner blister flange; and
wherein after the temporary attachment is broken, the outer blister is able to rotate in the aperture to align the opening with the at least one compartment.

2. The package of claim 1 , further comprising at least one detent in each of the inner body portion and outer body portion, wherein the detents engage to pause rotation of the outer blister in at least one position.

3. The package of claim 2 , wherein the inner body portion comprises multiple compartments and the detents engage to pause rotation at each of the compartments.

4. The package of claim 1 , wherein the inner body portion comprises a stop feature that fits into the opening when the package is in a closed position.

5. The package of claim 1 , wherein at least one of the cards comprises a tear-resistant paper or paperboard.

6. The package of claim 1 , wherein the inner blister and outer blister each comprises RPET or PLA.

7. The package of claim 1 , wherein the aperture is circular.

8. The package of claim 1 , wherein the blisters are approximately circular cylinders.

9. The package of claim 1 , wherein the outer blister fits closely within the aperture.

10. A method of forming a package, the method comprising:
providing a first card comprised of sheet material and having an aperture therein;
providing a second card comprised of sheet material;
providing an inner blister comprising an inner body portion and an inner blister flange, the inner body portion defining at least one compartment;
providing an outer blister comprising an outer body portion and an outer blister flange; the outer body portion including an opening, the outer body portion fitting over the inner body portion, the outer blister flange having a lesser diameter than inner blister flange diameter;
placing the outer blister over the inner blister;
placing the combined outer blister and inner blister so that their respective body portions protrude through the aperture;
bringing the first and second cards together with the inner and outer blister flanges between the cards, and
fastening the first and second cards together so that the inner blister flange is held stationary between the cards and the outer blister flange is substantially free of fixed attachment to the cards except for temporary attachment in the form of a lock tab extending radially outward from the outer blister flange and temporarily attached to at least one of the first card, second card, or inner blister flange;
wherein the outer blister flange is able to rotate in the aperture only after breaking the temporary attachment.

11. A package comprising:
a first card and a second card comprised of sheet material, the first and second cards at least partly attached together to form a two-ply structure;
an inner blister comprising an inner body portion and an inner blister flange, the inner body portion defining at least one compartment;
an outer blister comprising an outer body portion and an outer blister flange; the outer body portion fitting over the inner body portion, the outer body portion including an opening; and
an aperture in the first card to receive both blister body portions with both flanges positioned between the first and second cards and the inner blister flange attached to one or both of the cards;
wherein the outer blister flange is able to rotate in the aperture only after breaking a temporary attachment to at least one of the first card, second card, or inner blister flange; and
wherein the temporary attachment is a lock tab extending radially outward from the outer blister flange, the lock tab being attached to at least one of the first card, second card, or inner blister flange.

12. The package of claim 11 , wherein the lock tab is separated from the outer blister flange by the application of a twisting motion to the outer blister.

13. The package of claim 11 , wherein the lock tab is received in a notch in the inner blister flange.

14. The package of claim 11 , wherein the inner blister flange extends radially outward further than the outer blister flange, the inner blister flange being substantially sealed to at least one of the cards, and the outer blister flange being substantially not sealed to the cards.

15. The package of claim 11 , wherein the outer blister flange has a thickness, and the first card is embossed around the aperture to provide clearance for the thickness of the outer blister flange.

16. The package of claim 11 , wherein the outer blister can only be rotated after applying sufficient torque to break loose an adhesive or heat seal tack point attachment between the outer blister flange and at least one of the first card, second card, and inner blister flange.

17. The package of claim 11 , wherein the outer blister is able to rotate in the aperture to align the opening with the at least one compartment.

18. The package of claim 11 , further comprising at least one detent in each of the inner body portion and outer body portion, wherein the detents engage to pause rotation of the outer blister in at least one position.

19. The package of claim 18 , wherein the inner body portion comprises multiple compartments and the detents engage to pause rotation at each of the compartments.
