Abstract
The invention relates to a multichamber bag (1), the bag chambers (2, 3) of which are separated via a separating means (4), the squeeze-off means (5) of which temporarily separates the bag contents. To avoid being restricted to specific sheet types in the use of the material for the multichamber bag, in the region of the subsequent mixing opening an elastic sheet strip is arranged which serves as seal on actuation of the squeeze-off means (5).

- i) a strip of elastic sheeting arranged between said first and said second bag walls and
- ii) an external clamping means to fit over said bag walls proximate the location of said strip,
- whereby the deformation of said strip by application of said clamping means temporarily seals the thus formed chambers from each other.
