tearing the films.
2. A container according to claim 1, which is filled with at
least one chemical.

process for the preparation of an aqueous formulation, while
avoiding contact with the chemicals employed and maintaining
specified dosage rates, which process comprises adding said
containers with stirring, to a mixing tank containing water.
