Device for connection between a recipient and a container and method for assembling and using such a device

#This application claims priority benefit under 35 U.S.C. §371 to International Patent Application No. PCT/EP2012/060591 entitled DEVICE FOR CONNECTION BETWEEN A RECIPIENT AND A CONTAINER AND METHOD FOR ASSEMBLING AND USING SUCH A DEVICE, and filed by inventor Antoine Aneas on Jun. 5, 2012. International Patent Application No. PCT/EP2012/060591 claims priority to French Patent Application No. 11 54884, filed by inventor Antoine Aneas on Jun. 6, 2011.

#The invention relates to a device for a connection between a recipient provided with a neck closed off by a penetrable stopper and a container intended to be equipped with a needle, such a container for example possibly being a syringe. The invention also relates to a method for assembling such a connection device as well as a method for filling a container intended to be equipped with a needle, in which such a connection device is used.

#In the field of medicament packaging, it is known to store a freeze-dried medicament or the active ingredient of a medicament in a glass bottle, the neck of which is closed off by an elastomer stopper and crimped by an aluminum cap provided with a closure that can be torn. To reconstitute such medicaments, is known to eject the contents of the syringe into the bottle, then to recover the mixture. To that end, an equipment may be used like that described in WO-A-2006/085327, the implementation of which is relatively long and complex, inasmuch as certain manipulations, including rotations, must be done in a specific order that is not necessarily intuitive for an uninformed user. Furthermore, the known devices comprise a relatively large number of parts, which increases their cost and manufacturing time.

#The invention will be better understood and other advantages thereof will appear more clearly in light of the following description of one embodiment of a connection device according to its principle and methods implemented using the device, provided solely as an example and done in reference to the appended drawings, in which:

#FIG. 1 is an exploded perspective view in axial cross-section, over a quarter of its circumference, of a connection device according to the invention;

#FIG. 2 is an axial cross-section of the device of FIG. 1 above a bottle whereof the neck is closed off by a penetrable stopper;

#The connection device 10 shown in FIGS. 1 to 4 comprises a single-component base 20 made from a molded synthetic material, for example polycarbonate or ABS.

#This base 20 is provided with an annular part 21 from which four tabs 22 extend that are elastically deformable and the geometry of which allows them to be snapped around the outer collar 122 of the neck 120 of the glass bottle 110.

#The tabs 22 define a volume V22 between them for receiving the neck 120 when the device 10 is placed on the bottle 110, as shown in FIG. 3. In this configuration, an inner beak 24 of each tab 22 bears against a lower flank 134 of a cap 130 that surrounds the collar 122. This flank 134 in turn bears against a surface 124 of the collar 122 that is oriented toward the bottom 112 of the bottle 10.
