Abstract
A container for preparing a substance mixed from components which are inilly separated comprises two chambers (54, 56) separated from each other by a partitioning structure (52). One chamber (54) holds a liquid component and is closed by a sheet (53) of plastics material, and the other chamber (56) holds a powdery component and forms a mixing chamber. An actuating member (58) is movably disposed within the partitioning structure (52). The actuating member (58) includes a seal (64, 66) which is locked in the rest and storage position of the container and is released when the actuating member is moved into its actuated position in which the sheet (53) is perforated. In the actuated position, the seal (64, 66) functions as a valve to permit the liquid component to enter the mixing chamber (56) while preventing parts of the mixture or components thereof from flowing back from the mixing chamber (56) into the first chamber (54).
