ABSTRACT:
A package (1) for measured amounts of different photographic chemicals, which are to be stored apart and which are to be discharged simultaneously with a view to stirring into liquid, comprises an outer membrane (4) and at least one partition wall (5) that divides the chamber delimited by the outer membrane into two compartments (3,3). According to the invention, the package comprises a storage portion (12) and a neck portion (13), said partition wall extending across both portions, and those portions of the compartments which are disposed within the storage portion essentially containing the full, measured amounts of chemicals. The neck portion is so designed that a single cut along the cutting line (11) opens both chambers. The neck portion has such length that the chemicals may be retained in the package while the openings are immersed below a liquid surface to allow subsequent discharge of the amounts into the liquid without contacting the ambient air and without contacting each other before they have been discharged into the liquid.
