CA 2619225

The invention relates to a twin-chamber receptacle for accommodating and combining two separate components, at least one of which is liquid. Said twin- chamber receptacle comprises a cylindrical member (15) with one respective closure (20, 60) at each of the two ends (5, 70) of the member (15). The closure (60) located on the side of the chamber (5) containing the liquid component can be displaced by applying pressure. The twin-chamber receptacle further comprises a separating plug (40) which is disposed in the cylindrical member (15), defines the volume of the chamber (30, 50) located above and below, is used as a seal between the two chambers (30, 50), and can be displaced only when a greater amount of pressure is applied. The separating plug is provided with a continuous hole (42) which extends along the longitudinal axis of the separating plug (40) and encompasses a top section (42a) and a bottom section (42b). The top section (42a) of the hole (42) is closed in a liquid-tight manner towards the chamber (50) containing the liquid component by means of a molded element (45) that can be displaced by applying a small to a moderate amount of pressure.

L'invention concerne un contenant à deux chambres pour recevoir et combiner deux composants séparés dont un au moins est liquide. Ce contenant comprend un corps cylindrique (15) doté d'une fermeture (20, 60) à ses deux extrémités (5, 70), la fermeture supérieure (60) du côté de la chambre (50) contenant le composant liquide étant mobile sous l'action d'une pression. Le corps cylindrique (15) comporte un tampon de séparation (40) qui ne se déplace que sous l'action d'une pression accrue et qui définit le volume de la chambre supérieure et de la chambre inférieure (30, 50), le tampon de séparation servant d'obturation entre les deux chambres (30, 50) et étant traversé dans son axe longitudinal par une ouverture (42) ayant une section supérieure (42a) et une section inférieure (42b). La section supérieure (42a) de l'ouverture (42) est fermée de manière étanche aux liquides du côté de la chambre (50) contenant le composant liquide par un élément moulé (45) qui se déplace sous l'action d'une pression légère à moyenne.
