<p>PCT No. PCT/FR93/00545 Sec. 371 Date Feb. 3, 1994 Sec. 102(e) Date Feb. 3, 1994 PCT Filed Jun. 8, 1993 PCT Pub. No. WO93/25454 PCT Pub. Date Dec. 23, 1993.A mixer-conditioner for two components to be separately stored and extemporaneously mixed on their first utilization. The system comprises two compartments, each containing one of the components, an obturation element providing a tight seal between said compartments, the obturation element being movable between a closed position and an open position and arranged, when in the closed position, in a communication passage between the compartments, and being integral with a connection element engaged with a rotary actuation member whose operation causes the opening of the communication passage between the compartments by displacement of the obturation element in order to enable mixing of the components. The connection element is rotationally integral with the actuation member, but translationally free and guided, and the obturation element and the connection element comprise a screwing system comprising screw threads or at least one projection which cooperate with screw threads or at least one projection on the mixer conditioner such that the rotation of the actuation member causes the unscrewing of the obturation element or the connection element as well as the lifting of the obturation element which is disengaged from its closed position, while the connection element slides into the actuation member.</p> |
