Abstract:

A storage container is disclosed as well as a liquid storage system. Each container has walls of thin plastic material with the top and one sidewall of each container including a plurality of protuberances and the bottom and other sidewall including a plurality of indentations complementary to the protuberances so that, when like storage containers are brought into adjacent relationship, protuberances in one wall of one container are received in and mate with the indentations in one wall of the other container to facilitate maintaining vertical stacking and/or abutting side-by-side relationship of the system. The protuberances and indentations preferably have complementary slanting walls and each container wall preferably includes three such protuberances or indentations which are of substantial dimensions to also strengthen said walls. Piping is provided to interconnect the containers of the storage system and includes air conduit means opening into the top portion of each container and liquid conduit means opening into the bottom portion of each container, with liquid being withdrawn from the bottom portion of each container.
