Abstract

An assembly having an adaptor for coupling with a medical container having a septum. The adaptor includes a gripping member for securing the adaptor to the medical container; a pierceable elastomeric piece which, in an inactive state of the adaptor, does not contact the septum outer surface with pressure, and, in an active state of the adaptor, contacts the septum outer surface with pressure; a blister comprising a shell and a removable closing membrane forming a housing receiving the adaptor; a retaining system having a first retaining portion on the adaptor and a second retaining portion on the shell, the first retaining portion adapted, in a locked position of the retaining system, to cooperate with the second retaining portion, when the adaptor is not in the active state; and an unlocking portion adapted to transition the retaining system to an unlocked position, when the adaptor is in the active state.

First claim

The invention claimed is:

1. An assembly comprising:
an adaptor for coupling with a medical container having a neck closed by a septum, said septum having an outer surface directed towards an outside of the medical container, the adaptor comprising:
a gripping member for securing the adaptor to the medical container, said gripping member adapted to be mounted on the neck of said medical container;
a pierceable elastomeric piece which, in an inactive state of the adaptor, is not in contact with pressure with the outer surface of the septum, and which, in an active state of the adaptor, is in contact with pressure with the outer surface of the septum when said adaptor is placed on said medical container;
a blister comprising a shell and a removable closing membrane which form a housing receiving the adaptor with the adaptor in the inactive state, prior to the first use of the adaptor;
wherein the assembly further comprises:
a retaining system which comprises a first retaining portion arranged on the adaptor and a second retaining portion arranged on the shell, the first retaining portion being adapted, in a locked position of the retaining system, to cooperate with the second retaining portion, as long as the adaptor is not in the active state, so as to prevent the shell from being separated from the adaptor;
an unlocking member adapted to transition the retaining system to an unlocked position, when the adaptor is in the active state, in which unlocked position, the first retaining portion does not cooperate with the second retaining portion, thereby allowing removal of the shell.

2. The assembly according to claim 1 , wherein one of the first retaining portion and the second retaining portion comprise a notch and the other of the first retaining portion and the second retaining portion comprise a projecting member, the notch being opened towards the projecting member and the projecting member projecting towards the notch.

3. The assembly according to claim 1 , wherein the unlocking member comprises a wall which, when the adaptor changes from its inactive position to its active position, is designed to come in contact with a part of the retaining system and to cause said part to move or to break, in order to place the retaining system in the unlocked position.

4. The assembly according to claim 1 , wherein the adaptor further comprises a compressive member which comprises said pierceable elastomeric piece and which is movable relative to the gripping member from an inactive state, in which the pierceable elastomeric piece is not in contact with pressure with the outer surface of the septum when said adaptor is placed on said medical container towards an active state, in which the pierceable elastomeric piece is in contact with pressure with the outer surface of the septum when said adaptor is placed on said medical container.

5. The assembly according to claim 4 , wherein the first retaining portion is arranged on the gripping member, and wherein the unlocking member is arranged on the compressive member.

6. The assembly according to claim 1 , wherein the gripping member comprises a body, the first retaining portion is arranged on the gripping member and comprises at least one projecting member which projects from said body towards the shell, in the locked position, and which can be broken or deformed towards the unlocked position such that the at least one projecting member does not substantially protrude from the body.

7. The assembly according to claim 6 , wherein the projecting member comprises at least one breakable or flexible tab which projects outwardly and distally from the body, in the locked position, and which can be broken or deflected substantially against the body.

8. The assembly according to claim 1 , wherein the gripping member is a lateral clipping member having a U-shaped body adapted to be engaged on the neck of the medical container via an opening of the U-shaped body, a curved part of the U-shaped body partially surrounding the neck, the first retaining portion being arranged on the gripping member substantially on at least one free end of the U-shaped body.

9. The assembly according to claim 4 , wherein the gripping member comprises a first guiding portion adapted to cooperate with a second guiding portion arranged on the compressive member to guide the movement of the compressive member relative to the gripping member from the inactive state towards the active state, according to a longitudinal translation in a distal direction.

10. The assembly according to claim 9 , wherein a part of the second guiding portion forms the unlocking member.

11. The assembly according to claim 9 , wherein the first guiding portion comprises a substantially longitudinal leg and the second guiding portion comprises a substantially longitudinal housing which receives said leg and has an open distal end, a flexible tab extends from a distal end of the leg and comes out from the open distal end of the longitudinal housing.

12. The assembly according to claim 4 , wherein the compressive member comprises a first rotational blocking portion adapted to cooperate with a second rotational blocking portion arranged on an inner lateral face of the shell, to prevent rotation of the compressive member relative to the shell around a longitudinal axis.

13. The assembly according to claim 11 , wherein the first rotational blocking portion is located on the compressive member adjacent the longitudinal housing and wherein the second retaining means are located on the shell adjacent the second rotational blocking portion.

14. The assembly according to claim 13 , wherein the first rotational blocking portion comprises a substantially longitudinal slot and wherein the second rotational blocking portion comprises a substantially longitudinal rib having a notch for cooperating with the second retaining portion.

15. The assembly according to claim 1 , further comprising a medical container having a neck closed by a septum, said septum having an outer surface directed towards the outside of the medical container.
