Abstract

The bubble for a normally hanging bubble package is thermoformed with an integral base connected with the bottom of the bubble structure by a living hinge at which the base may be pivoted to engage the bottom of the bubble body structure and provide a support for the package in stand-up rather than hanging mode. Structure is provided for fastening the base to the bubble body; such structure may be a latching device comprising male and female elements formed integrally with the bubble at the bottom thereof and in the base, respectively, or may be separately applied adhesive or mechanical fastening devices. The bubble body and flange structure only are bonded to the supporting card leaving the base free to pivot at the hinge to engage the bubble body structure in optional stand-up mode of the package.

Claims

1. A thermoformed bubble for a bubble package usable either in a hanging or a free-standing display package comprising a bubble body, said body having peripheral flanges and a bottom portion, a base optionally usable to support said body in free-standing posture, said base being integral with said body and peripheral flanges and connected therewith by a living hinge crosswise of said bubble at said bottom portion of said body and peripheral flanges thereof, and means for fastening said base to said bottom portion of said body when pivoted about said hinge to a position normal to said peripheral flanges and engaging said bottom portion of said bubble.

2. A thermoformed bubble in accordance with claim 1 wherein said base is generally rectangular in plan, a long side of said base being connected with said living hinge.

3. A blister package comprising a supporting card and a bubble in accordance with claim 1 secured thereto, said card covering and being bonded to said bubble body and said peripheral flanges thereof but extending only to said living hinge whereby said base may be pivoted about said hinge independently of said card to provide a base for said blister in stand-up modes of said package.

4. A thermoformed bubble in accordance with claim 1 wherein said means for fastening said base to said bottom portion of said body comprises latching structure of latching element integral with said bottom portion of said body and mating recess integral with said base of said thermoformed bubble.

5. A blister package comprising a supporting card and a bubble in accordance with claim 4 secured thereto, said card covering and being bonded to said bubble body and said peripheral flanges thereof but extending only to said living hinge whereby said base may be pivoted about said hinge independently of said card to provide a base for said blister in stand-up mode of said package.

6. A thermoformed bubble in accordance with claim 4 wherein said base has a top surface sloping upwardly away from said hinge and skirt flanges depending from the sides thereof other than the side adjacent said hinge, the bottom edges of said skirt flanges having lateral peripheral flanges defining a plane with their under surfaces, said recess of said latching structure being entirely within the space between said top sloping surface of said base and said plane.

7. A thermoformed bubble in accordance with claim 6 wherein said bottom portion of said bubble body is flat and slopes upwardly away from said hinge and said latching element protrudes downwardly therefrom in a position to mate with said recess in said base in said latching structure.

8. A blister package comprising a supporting card and a bubble in accordance with claim 7 secured thereto, said card covering and being bonded to said bubble body and said peripheral flanges thereof but extending only to said living hinge whereby said base may be pivoted about said hinge independently of said card to provide a base for said blister in stand-up mode of said package.

9. A thermoformed bubble in accordance with claim 1 wherein said means for fastening said base to said bottom portion of said body comprises a latching structure in accordance with claim 6 and a second latching structure arranged side-by-side therewith.

10. A thermoformed bubble in accordance with claim 1 wherein said living hinge is weakened by a series of spaced cuts along said hinge at the bending line thereof whereby to minimize secondary bending alongside said bending line.

11. A blister package in accordance with claim 3 wherein said living hinge is weakened by a series of cuts along said hinge at the bending line thereof whereby to minimize secondary bending alongside said bending line.
