Carrier card for peel-open blisters
A package structure is disclosed for carrying blister cards of the peel-open variety, and for securing the blister cards within an outer sleeve enclosure.
1. A packaging structure for lockable placement into an outer sleeve, the packaging structure comprising a blister card and a carrier card combined together to form a single unit, the blister card comprising:
a polymeric sheet having first and second opposing surfaces;
at least one cavity formed in the polymeric sheet as at least one depression in the first surface and extending as at least one protrusion from the second surface; and
a lidding sheet mounted on the first surface and sealing the at least one cavity;
the carrier card comprising:
a carrier sheet having at least one aperture in which the at least one protrusion is received; and
a retention device associated with the carrier sheet to lockably engage with an outer sleeve,
wherein the carrier sheet is attached to the second surface of the polymeric sheet in a face-to-face contacting arrangement such that the lidding sheet remains uncovered by the carrier sheet.
2. The packaging structure of claim 1 , wherein the polymeric sheet is adhesively attached to the carrier sheet.
3. The packaging structure of claim 2 , wherein the lidding sheet is attached to the first surface by releasable adhesive.
4. The packaging structure of claim 2 , wherein the polymeric sheet is attached to the carrier sheet by a double-faced adhesive film or tape.
5. The packaging structure of claim 2 , wherein the polymeric sheet is attached to the carrier sheet by heat sealing.
6. The packaging structure of claim 1 , wherein the polymeric sheet is attached to the carrier sheet by welding.
7. The packaging structure of claim 1 , wherein the retention device comprises a locking flap hingedly connected to the carrier sheet, and the locking flap is folded backward over one of the first and second surfaces of the carrier sheet.
8. The packaging structure of claim 1 , wherein the retention device is an opening formed in the carrier sheet.
9. The packaging structure of claim 1 , further comprising a carrier sheet extension attached to the carrier sheet along a fold line and folded at an angle to the carrier sheet, and a node extending from the carrier sheet extension.
10. The packaging structure of claim 1 , wherein the carrier sheet is formed from a plastic material and the retention device comprises a projection formed on one of the first and second surfaces of the sheet.
11. The packaging structure of claim 1 , further comprising an outer sleeve with at least one mechanical feature to releasably engage the retention device.
12. The packaging structure of claim 1 , wherein the carrier card is formed from plastic.
13. The packaging structure of claim 12 , wherein the retention device comprises a locking flap hingedly connected to the carrier sheet along a fold line, the locking flap having at least one embossment, the fold line being an integral formation of the carrier card.
14. The packaging structure of claim 13 , wherein the fold line is co-formed simultaneously with the formation of the at least one embossment.
15. The packaging structure of to claim 13 , wherein the at least one first embossment extends substantially from the fold line.
16. The packaging structure of claim 15 , wherein the at least one first embossment terminates at a point at a first distance from the fold line, the first distance being no greater than 2.5 mm.
17. The packaging structure of claim 16 , wherein the at least one second embossment extends substantially from the fold line.
18. The packaging structure of claim 17 , wherein the at least one second embossment is co-formed simultaneously with the fold line and the at least one first embossment.
19. The packaging structure of claim 1 , wherein the lidding sheet has an inner surface and an outer surface, with the inner surface contacting the first surface, and the outer surface is not adhered to any other part of the blister card.
20. A packaging structure for lockable placement into an outer sleeve, the packaging structure comprising a blister card and a carrier card combined together to form a single unit, the blister card comprising:
a polymeric sheet having first and second opposing surfaces;
at least one cavity formed in the polymeric sheet as at least one depression in the first surface and extending as at least one protrusion from the second surface; and
a lidding sheet mounted on the first surface and sealing the at least one cavity;
the carrier card comprising:
a paperboard carrier sheet having at least one aperture in which the at least one protrusion is received; and
a retention device associated with the carrier sheet to lockably engage with an outer sleeve,
wherein the paperboard carrier sheet is attached to the second surface of the polymeric sheet in a face-to-face contacting arrangement such that the lidding sheet remains uncovered by the carrier sheet, and
wherein the lidding sheet has an inner surface and an outer surface, with the inner surface contacting the first surface, and
wherein no paperboard is directly adhered to the lidding sheet outer surface and no paperboard is directly adhered to the second surface of the polymeric sheet.
