Multi-layer medication carrier
View Patent ↗A multi-layer medication carrier or blister card may comprise a plurality of layers. A support layer is provided with one or more openings to receive corresponding blisters formed in a blister layer. A backing layer is provided over the blister layer to form one or more enclosures capable of holding unit doses of a medication. Perforations provided in at least the blister layer define unit dose packages. Dimples may be provided in the blister layer within a boundary defined by the perforations, which dimples may be used to ensure subsequent ejection of each unit dose package. An adhesive-free region in the backing layer may be provided in alignment with the perforations defining each unit dose package to further ensure proper ejection. Additionally, a partial-depth cut in the backing layer may be provided in substantial alignment with each blister, thereby facilitating removal of the unit dose of medication.
1. A medication carrier comprising:
a blister layer comprising a plurality of blisters arranged in a two-dimensional array, a ribbing between each of the plurality of blisters and a plurality of first perforations corresponding to the plurality of blisters, each one of the plurality of first perforations defining a boundary between the ribbing and an individually-ejectable, unit dose package comprising a corresponding blister of the plurality of blisters; and
a backing layer, coupled to a first side of the blister layer such that the plurality of blisters and the backing layer form a plurality of enclosures each for holding at least one unit dose of a medicament, the backing layer further comprising a plurality of partial-thickness cuts through a thickness of the backing layer corresponding to and substantially aligned with the plurality of blisters.
2. The medication carrier of claim 1 , each one of the plurality of blisters further comprising at least one dimple disposed within the boundary.
3. The medication carrier of claim 1 , each one of the plurality of blisters further comprising at least one first web member interrupting a corresponding one of the plurality of first perforations and attaching the blister to the ribbing.
4. The medication carrier of claim 3 , the backing layer further comprising a plurality of second perforations substantially aligned with the plurality of first perforations.
5. The medication carrier of claim 4 , the backing layer further comprising, for each one of the plurality of second perforations, at least one second web member interrupting the second perforation.
6. The medication carrier of claim 4 , the backing layer further comprising an adhesive applied to a second side of the backing layer facing the blister layer, except that a plurality of adhesive-free regions is provided corresponding to the plurality of second perforations.
7. The medication carrier of claim 1 , each of the plurality of partial-thickness cuts substantially aligned with an opening perimeter of a corresponding one of the plurality of blisters.
8. The medication carrier of claim 1 , further comprising:
a support layer, coupled to a second side of the blister layer, comprising a plurality of openings, each of the plurality of openings configured to receive a corresponding one of the plurality of blisters.
9. A medication carrier comprising:
a blister layer comprising a plurality of blisters formed therein, each of the plurality of blisters for holding a unit dose of a medicament, the blister layer further comprising a ribbing between each of the plurality of blisters and a plurality of first perforations corresponding to the plurality of blisters, each one of the plurality of first perforations defining a boundary between the ribbing and an individually-ejectable, unit dose package comprising a corresponding blister of the plurality of blisters; and
a backing layer, coupled to the blister layer, comprising a plurality of second perforations substantially aligned with the plurality of first perforations and further comprising an adhesive applied to a side of the backing layer facing the blister layer, except that a plurality of adhesive-free regions is provided corresponding to the plurality of second perforations.
10. The medication carrier of claim 9 , wherein each one of the plurality of adhesive-free regions includes a corresponding one of the plurality of second perforations.
11. The medication carrier of claim 9 , the backing layer further comprising, for each one of the plurality of second perforations, at least one web member interrupting the second perforation.
12. The medication carrier of claim 9 , the backing layer further comprising a plurality of partial-thickness cuts through a thickness of the backing layer corresponding to and substantially aligned with the plurality of blisters.
13. The medication carrier of claim 12 , each one of the plurality of partial-thickness cuts substantially aligned with an opening perimeter of a corresponding one of the plurality of blisters.
14. The medication carrier of claim 9 , each one of the plurality of blisters further comprising at least one dimple disposed within the boundary.
15. The medication carrier of claim 9 , further comprising:
a support layer, coupled to a second side of the blister layer, comprising a plurality of openings, each one of the plurality of openings configured to receive a corresponding one of the plurality of blisters.
16. The medication carrier of claim 9 , the blister layer further comprising the plurality of blisters arranged in a two-dimensional array.
17. A medication carrier comprising:
a blister layer comprising a plurality of blisters formed therein, the blister layer further comprising a ribbing between each of the plurality of blisters and a plurality of first perforations corresponding thereto, each one of the plurality of first perforations defining a boundary between the ribbing and an individually-ejectable, unit dose package comprising a corresponding blister of the plurality of blisters, each blister of the plurality of blisters further comprising at least one dimple disposed within the boundary; and
a backing layer, coupled to a first side of the blister layer such that the plurality of blisters and the backing layer form a plurality of enclosures each for holding at least one unit dose of a medicament.
18. The medication carrier of claim 17 , each blister of the plurality of blisters further comprising a plurality of dimples disposed within the boundary.
19. The medication carrier of claim 18 , each blister of the plurality of blisters further comprising four dimples disposed within the boundary.
20. The medication carrier of claim 17 , the at least one dimple disposed outside an opening perimeter of the blister.
21. The medication carrier of claim 17 , the at least one dimple aligned to receive at least one pin of a punch used to eject each unit dose package.
22. The medication carrier of claim 17 , the backing layer further comprising a plurality of partial-thickness cuts through a thickness of the backing layer corresponding to and substantially aligned with the plurality of blisters.
23. The medication carrier of claim 17 , the backing layer comprising a plurality of second perforations substantially aligned with the plurality of first perforations, the backing layer further comprising an adhesive applied to a side of the backing layer facing the blister layer, except that a plurality of adhesive-free regions is provided corresponding to the plurality of second perforations.
