Patent

CA 2251159

A container system for containing and preserving gas generating solutions such as bicarbonate-containing solutions is provided. The system includes an outer container or barrier that is gas impermeable. The system also includes an indicator for visually indicating when gas has been permitted to leak or escape from the outer container thereby changing the physical characteristics of the gas generating solution.

L'invention concerne un système de contenant permettant de recevoir et de conserver des solutions génératrices de gaz (par exemple, solutions renfermant du bicarbonate). Le système comporte un contenant ou une enveloppe externe qui est imperméable aux gaz. Il comprend aussi un indicateur visuel qui signale l'émission ou l'échappement de gaz hors de l'enveloppe externe, ce phénomène correspondant à une évolution des caractéristiques physiques de la solution génératrice de gaz.
