Abstract: A connector for connecting two containers includes a first portion releasably secured to the neck of the first container and a second portion having an access opening. A closure member for sealing the access opening of the connector includes a cover for sealably closing the access opening, the cover being fixed to the connector so as to include a breakable point of attachment and a zone of weakness disposed on the periphery of the cover. The cover includes a tab disposed generally perpendicular to the cover and a strut angularly disposed between the tab and the cover such that the exertion of pressure substantially normal to the tab causes the cover to release from the connector at the zone of weakness and the rotation of the cover causes release of the cover from the connector at the breakable point of attachment.

Abstract: Packaging assembly intended for the extemporaneous preparation of suspensions or solutions of a solid active product in a liquid product, the active product having been freeze-dried and being contained in a flask A, and the liquid product being contained in a flask B closed by a dropper (30), a connection member (16) enabling to put in communication the two flasks for the purpose, in a first step, to cause the liquid product to pass from flask B into flask A containing the solid product, then, in a second step, to reverse the assembly and aspirate into flask B the suspension or solution thus formed. Flask A containing the active product is closed by an elastic stopper (10) having a central perforation (12) closed by a perforable operculum (14) which is perforated by the dropper when the flasks are put in communication by means of the connection member.
