DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to connection with a closed container comprising a neck, the opening of which is plugged by a stopper made of a relatively soft material, for example made of elastomer, and provided with an external annular lip, the said rigid container being, for example, made of glass. As a non-exclusive preference, this connection is used to provide communication between, on the one hand, the aforementioned closed container and, on the other hand, another closed container comprising an end piece, the opening of which is also plugged by a stopper made of a relatively soft and elastic material. This definition applies to various applications among which is included therapy or the administration of a medicinal product, in which case the closed container contains, for example, an active ingredient in the form of a powder, and the other container consists of a flexible pouch containing a liquid medium which can dissolve the powder or active ingredient of the container or place it in suspension, this all being in order to obtain a medicinal preparation in liquid form ready to be administered to the patient.
A connection device, or connector, intended to be assembled in a leaktight manner, on the one hand, with a closed container as previously described, comprising tearable or puncturable tamperproofing means keeping the stopper sterile and, on the other hand, with another container as previously described, itself also comprising tearable or puncturable tamperproofing means keeping the stopper present in the opening of the end fitting sterile without having to remove the tamperproofing means of the two containers to be connected, is described and proposed in accordance with the document WO-9003536.
This connection device comprises: the stopper, and also covered around the annular lip by the tamperproofing means covering and sealing the whole of the external part of the stopper; this cap is also designed to be fitted over the neck 3 and for this purpose has radially outward elasticity so that it can snap-fasten, by means of an internal annular ridge, under the annular lip of the neck of the container; moreover, this cap comprises a coaxial collar lengthening it and forming an internal bore, which will be dealt with later, attached to and arranged inside the cap, including a transverse wall designed to come into contact with the external part of the stopper; this transverse element comprises an axial end piece or sleeve tube fitted in a leaktight manner over the perforating end of the needle which will be dealt with later, this sleeve tube being closed and perforable at its end sealing the needle, comprising a piston mounted so that it can slide in the bore of the collar of the cap, and a central needle passing through the said piston and including the aforementioned perforating end, capped inside the sleeve tube or end piece of the transverse element made of elastomer.
Such a device is not designed or suited to providing tamperproofing of the container with its stopper, because this tamperproofing is obtained by other means already present on the container. In particular, this device can be fitted and removed at will, relative to the plugged container.
Further, this device provides only temporary sealing, at the moment of connection, with each of the two containers in direct contact with their own sealing means.
A device for connection with a closed container, as previously defined, and completely closing this container, but without tamperproofing it in the sense that it is not put in place permanently on the container is described in accordance with the document U.S. Pat. No. C4624667.
This device interacts with a specific, non-standardized container which can be distinguished from the one described earlier by the presence of an annular rim running round the outside of the external annular lip and forming a housing for a flat, which is also annular, belonging to the stopper which in this case has a specific special shape.
The connection device proper comprises: stopper
