Abstract

The invention relates to a protective housing for a biopharmaceutical liquid bag having a lower shell with a bottom and side walls, and an upper shell. The upper shell includes a housing for receiving the bag, and can be inserted into the lower shell, in such a way that the opening of the housing is adjacent to and facing the bottom of the lower shell, and in such a way that the upper shell is laterally held in place between the side walls of the lower shell.

First claim

The invention claimed is:

1. Protective housing for a biopharmaceutical liquid bag, comprising:
a lower shell comprising a bottom and side walls,
an upper shell:
which comprises a housing for receiving the bag, and
protuberances surrounding said housing and configured to secure at least one tube coming from said bag along an exterior facing side of said housing,
and wherein said upper shell is capable of being inserted into the lower shell,
in such a way that a first opening of the housing is adjacent to and facing the bottom of the lower shell,
in such a way that an entire volume of the bag is received within the housing,
in such a way that the protuberances are between the side walls of the lower shell,
and in such a way that the upper shell is laterally held in place between the side walls of the lower shell.

2. Protective housing according to claim 1 , wherein a distance between the first opening of the housing and the bottom of the lower shell is at least three times less than a depth of the housing.

3. Protective housing according to claim 1 , wherein the upper shell is capable of being inserted into the lower shell in such a way that the first opening of the housing is in contact with the bottom of the lower shell.

4. Protective housing according to claim 1 , wherein the housing comprises a housing bottom, and housing side walls extending substantially perpendicularly to said bottom.

5. Protective housing according to claim 4 , wherein the upper shell is capable of being inserted into the lower shell in such a way that an outer periphery of the upper shell is guided by the side walls of the lower shell.

6. Protective housing according to claim 1 , wherein the upper shell has outer side walls surrounding side walls of the housing and extending substantially parallel to the side walls of the housing.

7. Protective housing according to claim 1 , wherein a thickness of the upper shell is less than a thickness of the lower shell.

8. Protective housing according to claim 7 , wherein the upper shell is capable of being fully inserted into the lower shell.

9. Protective housing according to claim 1 , wherein the upper shell is capable of being inserted into the lower shell in such a way as to not extend outside the lower shell in height.

10. Protective housing according to claim 1 , wherein the upper shell also comprises, at least on one end of the housing for receiving a bottom of the bag, an edge surrounding the first opening of the housing, extending substantially in the plane of the first opening of the housing.

11. Protective housing according to claim 10 , further comprising notches located on a side wall of said upper shell and said end of the housing, wherein a portion of the edge of the upper shell, situated between the notches, is arranged in such a way that, when a handle of a bottom of the bag attaches to said notches, the connection between the handle and the bottom of the bag is wound around said portion of the edge.

12. Protective housing according to claim 1 , wherein the upper shell comprises two lateral side walls and two longitudinal side walls, said lateral and longitudinal walls surrounding the housing
wherein a first longitudinal side wall of said two longitudinal side walls comprises notches configured such that a handle of a bottom of the bag is capable of being attached to the notches.

13. Protective housing according to claim 1 , wherein the upper shell further comprises a first side wall located at a first longitudinal end of said upper shell, and
wherein a portion of said first side wall comprises a recess which defines a passage for a tube or tubes of the bag extending from said first opening of said housing to an exterior of the upper shell.

14. Protective housing according to claim 13 , wherein the lower shell extends further longitudinally than said upper shell when said upper shell is inserted in said lower shell, the lower shell comprising a first portion for receiving said upper shell and a second portion which bounds a second opening for the tube or tubes of the bag between the first longitudinal end of said upper shell and a first longitudinal end of said lower shell, said second opening being in fluid communication with said passage and the exterior.

15. Protective housing according to claim 14 , wherein said side walls of the lower shell comprise a recess arranged towards the inside of the lower shell and situated above or below an outlet of aid second opening.

16. Protective housing according to claim 1 , wherein the upper shell and the lower shell are made of plastic.

17. Protective housing according to claim 16 , wherein the plastic is polyethylene terephthalate glycol (PETG).

18. Protective housing according to claim 1 , wherein the upper shell and the lower shell are made from a same common material, and an outer cover that covers the upper shell and that closes the lower shell, when there is one, is also made from the same common material.

19. Protective housing according to claim 1 , wherein the protective housing is capable of being stacked.

20. Protective housing according to claim 19 , further comprising a second housing and wherein the housing and the second housing are stacked one in the other, the bottom of the lower shell of the housing above bears against either a cover of the housing below or on the upper shell of the housing below.

21. Protective housing according to claim 1 , wherein the side walls of the lower shell comprise one or several shoulders, parallel to the plane of the bottom of the lower shell, against which a cover bears.

22. Protective housing according to claim 1 , wherein the side walls of the lower shell comprise one or several shoulders, parallel to the plane of the bottom of the lower shell, against which the upper shell bears.

23. Protective housing according to claim 1 , wherein the side walls of the lower shell comprise one or several shoulders, orthogonal to the plane of the bottom of the lower shell, against which the upper shell longitudinally abuts when it is inserted into the lower shell.

24. Protective housing according to claim 1 , wherein the upper shell comprises one or several longitudinal ends having notches configured to attach to the bag.

25. Protective housing according to claim 1 , wherein the protuberances are formed in a first side wall of the upper shell opposite a second side wall of the upper shell for guiding one or several tubes.

26. Protective housing according to claim 1 , wherein a distance between the opening of the housing and the bottom of the lower shell is greater than or equal to half, of the depth of the housing, and at least when the upper shell is inserted into the lower shell, said protuberances are surrounding the housing in such a way as to be able to hold in place around the housing at least one tube coming from the bag.

27. Protective assembly for a biopharmaceutical liquid bag comprising:
a protective housing according to claim 1 ,
a biopharmaceutical liquid bag placed in said protective housing.

28. Protective assembly for a biopharmaceutical liquid bag according to claim 27 , wherein:
the bag is longitudinally fastened in the protective housing,
the bag is not fastened elsewhere than longitudinally in the protective housing.

29. Protective assembly for a bag for receiving a biopharmaceutical liquid compri
