A device comprising a generally cylindrical plastics container sealed at its ends and having an area intermediate said ends defined by one or more temporary seals, thereby dividing the container into two compartments and an intermediate area between the compartments, is provided. The compartment of the container adjacent to one end thereof contains a first material and the compartment of the container adjacent to the other end thereof contains a second material in which the first material is to be dispersed or dissolved prior to use. The intermediate area contains neither the first nor the second material and the temporary seal or seals is or are arranged so that it or they can be broken by finger pressure to permit communication between the outer compartments, thereby permitting mixing of the first and the second materials.
A device which comprises a generally cylindrical plastics container at its ends having temporary seals therein to thereby divide the container into three compartments, one at each end and one intermediate those at each end, wherein that compartment of said container adjacent to one end thereof contains a first material and that compartment of said container adjacent to the other end thereof contains a second material in which the first material is to be dispersed or dissolved prior to use, characterized in that (a) said intermediate compartment contains a bed but neither said first material nor said second material, and (b) said temporary seals are arranged so that they can be broken by finger pressure to permit communication between the compartments, thereby permitting mixing of said first material and said second material.
