Patent ID: 6951275

Claim:
A complex packaging device for separately containing two or more products to be mixed at the time of use, comprising: two or more enclosures communicating with each other by an intermediate tubular portion of the same or smaller diameter, one of the enclosures being provided with an openable stopper, separated by a stoppering partition and each of said enclosures is filled with one of the products and with a gaseous fluid compatible with each of said products, said gaseous fluid being substantially subject to pressures different from the atmospheric pressure, wherein the pressures of both enclosures separated by the stoppering partition are either above or below the limits of the normal oscillations of the atmospheric pressure, said pressures exerting an equal force on both sides of the stoppering partition, maintaining a functional balance between both enclosures, and wherein said stoppering partition is formed by an edible natural material located in the intermediate tubular portion along which it may move slightly, without losing its stoppering capacity, because of the forces formed in both enclosures by small pressure differences in the gaseous fluids contained therein.
