Abstract
The container (10) comprises a first compartment (11) and a second compartment (12) which are separated by a central cylindrical throat (13). The compartment (11) is extended by a neck (14) which comprises a first region (15) adjacent to the upper open end of the container and a second region (16) located between the first region (15) and the inside of the container. The region (15) has one section which is greater than that of region (16). Both regions (15, 16) are substantially cylindrical. The section of the second region (16) is substantially identical to that of the central cylindrical throat (13). An intermediate sealing plug (17) compressed into the central cylindrical throat (13) allows sealed storage of two different substances in the compartments (11) and (12). A sealing member (23) inserted into region (15) of the neck (14) is displaceable between a first, storage position, in which it acts as a seal, and a second, ready for use position.
