Abstract: This assembly is of the type including: a vessel (4) for containing liquid, the vessel (4) having a neck (14); a dispensing dropper end fitting (6) disposed at the end of the neck (14); and a cap (8) for closing the vessel (4), provided to be screwed onto the neck (14). In a preferred embodiment, the cap (8) and the neck (14) have safety element preventing the cap (8) from being unscrewed simply by applying an unscrewing torque, and allowing the cap (8) to be unscrewed when an additional action is applied together with the torque for unscrewing the cap (8).

Abstract: This assembly is of the type including: a container (4) for containing the liquid; a liquid dispensing device (6), including: a spout (20) through which liquid can pass out and air can come in; and elements (28) for filtering liquid and air passing through the spout (20); and a cap (14) for closing the container (4). One feature of the invention is that the assembly includes elements (38, 41, 39) for encouraging the entrance of air and/or the return of a residual quantity of liquid trapped in the spout (20) after dispensing some liquid, through the filtering elements (28), into the container (4).

Abstract: This end-piece is of the type including two filtering membranes and support portions for supporting the membranes and channelling the fluid through the membranes. According to one aspect of the invention, it includes a connection portion which is moulded over the support portions in order to fix them together and the support portions include an upper support portion, a lower support portion and an intermediate support portion which is arranged between the upper support portion and the lower support portion, a membrane is retained between the upper support portion and the intermediate support portion and a membrane is retained between the intermediate support portion and the lower support portion and the membranes are overmoulded by the connection portion.
