Abstract:
A container for separately containing a first flowable material and a second flowable material until the mixing of the first and second flowable material is desired, comprising:(i) a first chamber containing the first flowable material and having a first head space comprising gas at a pressure greater than or equal to atmospheric pressure; (ii) a second chamber containing the second flowable material, the second flowable material containing gas, and the second chamber having a second head space comprising gas at a pressure greater than atmospheric pressure; (iii) means for opening the first chamber to an environment external to that chamber, for reducing pressure in the first chamber; (iv) means for transferring gas between the first and second chambers; and (v) means for transferring the second flowable material into the first chamber for mixing with the first flowable material, when the pressure in the first chamber is reduced, which transferring means comprises conduit means which opens at one end into said second chamber in the second flowable material below said second head space and which is configured so that on reduction of pressure in the first chamber, the conduit means conveys said second flowable material upwardly from said second chamber and then directs it downwardly into said first chamber for mixing with the first flowable material.
