Abstract

An envelope is configured to hold, support, and protect an article such as a blood bag during transportation under cryogenic temperatures. The envelope includes a single piece component (e.g., a monolithic component), including multiple panels that are configured to fold to form an enclosure that surrounds the article such as the blood bag for support and protection of the article such as the blood bag.

First claim

What is claimed is:

1. An envelope for transporting a blood bag, the envelope comprising:
a plurality of panels configured to transition from a pre-assembled state to an assembled state, wherein in the assembled state, the envelope includes:
a front panel in the plurality of panels and a back panel in the plurality of panels, wherein the front panel and the back panel define a cavity in a thickness direction between the front panel and the back panel;
a first redundant seal disposed on a first side of the envelope, and
a second redundant seal disposed on a second side of the envelope.

2. The envelope of claim 1 , wherein the envelope is monolithic.

3. The envelope of claim 1 , wherein in the assembled state, a crease is formed on a bottom side of the envelope between the front panel and the back panel.

4. The envelope of claim 1 , wherein the cavity is configured to receive the blood bag therein.

5. The envelope of claim 1 , wherein in the assembled state, the envelope includes a third redundant seal disposed on a top side of the envelope.

6. The envelope of claim 1 , wherein each of a set of panels in the plurality of panels includes an adhesive disposed thereon, the adhesive configured to couple a first panel in the set of panels to a second panel that is not in the set of panels.

7. The envelope of claim 6 , wherein the set of panels includes panels that each extend outward from one of the front panel or the back panel.

8. The envelope of claim 1 , wherein the envelope is made from a polymeric material.

9. The envelope of claim 1 , wherein in the pre-assembled state, the envelope further comprises a plurality of fold lines, the plurality of fold lines configured to guide the transition from the pre-assembled state to the assembled state.

10. A method of forming an envelope for transporting a blood bag, the method comprising:
folding a plurality of panels, the plurality of panels including at least a front panel and a back panel,
mating a first set of panels in the plurality of panels to a second set of panels in the plurality of panels; and
in response to the mating, forming a cavity defined in a thickness direction between the front panel and the back panel, the cavity configured to receive the blood bag therein, the mating forming a first redundant seal on a first side of the envelope and a second redundant seal on a second side of the envelope.

11. The method of claim 10 , further comprising disposing the blood bag in the cavity.

12. The method of claim 11 , further comprising folding a remaining set of panels in the plurality of panels to form a third redundant seal on a top side of the envelope.

13. The method of claim 10 , wherein in response to folding the plurality of panels, a crease is formed on a bottom side of the envelope.

14. The method of claim 10 , further comprising:
disposing the blood bag in the cavity; and
folding a remaining set of panels to form an assembled state of the envelope.

15. A method of transporting a plurality of blood bags, the method comprising:
folding an envelope in a pre-assembled state to an assembled state;
disposing a blood bag in the envelope one of prior to the folding or at an intermediate step during the folding;
disposing the envelope in a carrying bag; and
transporting the carrying bag from a first location to a second location.

16. The method of claim 15 , further comprising disposing a plurality of envelopes in the assembled state in the carrying bag, each of the plurality of envelopes in the assembled state including a respective blood bag in the plurality of blood bags, the plurality of envelopes including the envelope.

17. The method of claim 16 , further comprising disposing an absorbent material layer between each of the plurality of envelopes in the assembled state.

18. The method of claim 15 , wherein in the assembled state, the envelope includes a cavity defined in a thickness direction between a front panel and a back panel of the envelope, the blood bag disposed in the cavity.

19. The method of claim 15 , wherein the envelope includes a polymeric material.

20. The method of claim 19 , wherein the folding the envelope in the pre-=assembled state to the assembled state further includes:
folding a plurality of panels, the plurality of panels including at least a front panel and a back panel, and
mating a first set of panels in the plurality of panels to a second set of panels in the plurality of panels to form a cavity configured to receive the blood bag.
