Patent ID: 7699079

Claim:
A process for dissolving, reducing the density, or reducing the viscosity of a first material comprising the steps of: filling with a first material a reusable flexible bulk container which can be positioned within and removed from a second container, said flexible bulk container comprising: a body defining a cavity; at least one inlet for introducing said first material, at least one outlet, and at least one vent, each providing communication with the cavity; and a material delivery system assembly having: at least one manifold, a portion of which is positioned within the cavity of the flexible bulk container, the at least one manifold having a shell, an interior region and an inlet accessible from outside of the cavity of the flexible bulk container and a plurality of passageways strategically positioned along the manifold extending from the internal region, through the shell, to, in turn, place the interior of the manifold in communication with the cavity, and wherein the at least one manifold is oriented within the flexible bulk container such that the outer shell of said manifold is coupled to each of a front and a back wall of the flexible bulk container, and the passageways are positioned along at least one of a side wall of the flexible bulk container; supplying the cavity with a second liquid material through the material delivery system assembly; dissolving, reducing in density, or reducing in viscosity the first material by contacting with the second material to form a resulting material; venting air and gas through the vent of the flexible bulk container; and evacuating the resulting material through the at least one opening of the flexible bulk container.
