摘要

Mixer device consisting of two receptacles 1 and 2 each filled with a product to the mixed and assembled together in a fluid-tight manner by their necks 4 and 8. The stopper 3 provided with a rod 5 closes receptacle 1 and the passage between the two receptacles. Receptacle 1 is made in the form of a bellows 9. Compression of the bellows 9 by pressing on the obturating top 6, pushes out the stopper 3 by means of the rod 5 and expels the content of receptacle 1 under pressure into receptacle 2. The frangible tubular element 20 locks the obturating top 6 in its initial position and prevents it from moving axially before the destruction of the element 20. <IMAGE>
