A container for separately storing flowable materials but allowing mixing of materials when required

摘要

A container is disclosed for separately containing a first flowable material and a second flowable material until the mixing of the first and the second flowable materials are desired. The first chamber contains the first flowable material and having a first head space comprising a gas at a pressure greater than or equal to atmosphere pressure. A second chamber containing the second gas containing flowable material comprises a second head space comprising a gas at a pressure greater than atmospheric pressure. Further means are disclosed for opening the first chamber to an environment external to the chamber for reducing pressure in the first chamber. The second flowable material is transferred into the first chamber for mixing with the first flowable material when the pressure in the first chamber is reduced by means of a transferring means comprising a conduit extending upwardly form a lower opening immersed in the second flowable material below the second head space, to an upper opening immersed in the first flowable material. The conduit is capable of containing an airlock releasable on the reduction of pressure in the first chamber to allow transfer of the second flowable material along the conduit means to mix with the first flowable material.
