Abstract
Abstract Apparatus and a system are disclosed for storing and transporting material as well as conducting required batch processing operations on the material within a container having exterior fittings designed for use in conjunction with a quick connect-disconnect docking station. A member of the docking station interlocks with containers of different size in a positive self-positioning manner. Blending, mixing, chemical reaction, and reconstituting of liquid and/or solid material in the container or inverting of the container itself can then be accomplished without having to transfer the material to additional process equipment. In addition to the significant materials handling advantages obtained, the apparatus and system virtually eliminate pollution and contamination problems for batch processing operations.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
199 words
An enclosed multiwall container comprising: an upper end wall member; a lower end wall member; side wall members; each side wall member connected to said upper end wall member and said lower end wall member; at least one vertical channel member connected to said upper end wall member and said lower end wall member, each said channel member separating adjacent side wall members and turned outwardly to form a recessed corner along adjacent side wall members; at least two adjacent side wall members having horizontal means extending along each side wall member from a recessed corner, said horizontal means adapted for interconnection of the container with V-shaped arms of a retaining device; and said upper end wall member and lower end wall member each having two separate projecting hourglass shaped members positioned parallel to each other, each said hourglass shaped member being narrowest at the midsection of its hourglass shape, and the hourglass shaped member projecting from the upper end wall member are of slightly different size than the hourglass shaped members projecting from the lower end wall member such that hourglass shaped members on different containers will nest with each other when one container is stacked on another.
Claim 2
Dependent Claim
