Abstract

The present invention relates to an assembly ( 101 ) comprising: an injection device ( 1 ) comprising a container ( 2 ) for a product, said container comprising a distal tip ( 3 ), an adaptor ( 5 ) comprising a ring ( 6 ) mounted onto said distal tip ( 3 ), characterized in that said assembly ( 101 ) further comprises a heat-shrinkable film ( 9 ) covering part ( 2 a ) of said container ( 2 ) and part ( 5 a ) of said adaptor ( 5 ), said film ( 9 ) maintaining said adaptor ( 5 ) blocked in rotation and in translation with respect to said container ( 2 ) when said film ( 9 ) is in its heat-shrunk condition. The invention further relates to a method for manufacturing such an assembly.

First claim

What is claimed is:

1. An assembly comprising:
an injection device comprising a container for a product, said container comprising a distal tip encompassing a channel providing a passageway for transfer of said product;
an adaptor comprising a ring mounted onto said distal tip, said ring including an internally threaded portion and an inner projection extending radially inwardly, wherein said ring of said adaptor is mounted on said distal tip by friction between said inner projection and said distal tip and wherein said distal tip extends into said internally threaded portion of said adaptor with a distal end of said distal tip being disposed beyond a distal end of said adaptor; and
a heat-shrinkable film covering at least part of said container and at least part of said adaptor, said heat-shrinkable film not covering a distal end of said ring so as to allow access to said internal thread without removal of any portion of said heat-shrinkable film covering at least part of said container and at least part of said adaptor, said heat-shrinkable film maintaining said adaptor blocked in rotation and in translation with respect to said container when said heat-shrinkable film is in its heat-shrunk condition.

2. The assembly according to claim 1 , wherein said heat-shrinkable film is made of a thermoplastic material selected from the group consisting of polyvinyl chloride (PVC), a polyethylene terephthalate (PET), oriented polystyrene (OPS), oriented polypropylene (OPP), polylactic acid (PLA) and mixtures thereof.

3. The assembly according to claim 2 , wherein said heat-shrinkable film is made of polyvinyl chloride.

4. The assembly according to claim 1 , wherein said assembly further comprises a label imprisoned between said heat-shrinkable film and said container and adaptor.

5. The assembly according to claim 1 , wherein said assembly further comprises a label located on said heat-shrinkable film.

6. The assembly according to claim 1 , wherein said assembly further comprises a plug mounted on said adaptor.

7. The assembly according to claim 6 , wherein the heat-shrinkable film also covers at least part of said plug.

8. The assembly according to claim 7 , wherein said heat-shrinkable film is provided with an annular breakable line located on a part of the heat-shrinkable film that covers part of said plug.

9. The assembly according to claim 1 , wherein said heat-shrinkable film is at least partially glued on at least one of said container or adaptor.

10. The assembly according to claim 1 , wherein said heat-shrinkable film is provided with writing.

11. The assembly according to claim 1 , wherein said assembly further comprises a label imprisoned between said heat-shrinkable film and said container.

12. The assembly according to claim 1 , wherein said assembly further comprises a label imprisoned between said heat-shrinkable film and said adaptor.

13. The assembly according to claim 1 , wherein said product comprises a medical fluid.

14. A method for manufacturing an assembly according to claim 1 comprising the following steps:
providing an injection device comprising a container for a product, said container comprising a distal tip encompassing a channel providing a passageway for transfer of said product, and a suitable adaptor including a ring, said ring including an internally threaded portion and an inner projection extending radially inwardly,
fitting the suitable adaptor on the distal tip of said injector device, wherein said ring of said adaptor is mounted on said distal tip by friction between said inner projection and said distal tip and wherein said distal tip extends into said internally threaded portion of said adaptor with a distal end of said distal tip being disposed beyond a distal end of said adaptor,
bonding a heat-shrinkable film on the assembly so as to cover at least part of said adaptor and at least part of said container but not a distal end of said ring so as to allow access to said internal thread without removal of any portion of said heat-shrinkable film that covers at least part of said adaptor and at least part of said container, and
heating the heat-shrinkable film until it shrinks and tightly covers said part of said container and said part of said adaptor so as to maintain said adaptor blocked in rotation and in translation with respect to said container.

15. The method according to claim 14 , wherein a plug is further provided and mounted on the adaptor, and said heat-shrinkable film is sized so as to further cover at least part of said plug.

16. The method according to claim 15 , wherein, before bonding the heat-shrinkable film on the assembly, a breakable line is designed on a part of the heat-shrinkable film intended to cover part of said plug.

17. The method according to claim 14 , wherein the heat-shrinkable film is in the form of a rectangular sheet when bonded on the assembly.

18. The method according to claim 14 , wherein said product comprises a medical fluid.
