Years ago when I was a distributor we sold a lot of 55 gallon drums of metalworking coolant concentrate. They were typically mixed with water at a 5-10% dilution. The drums were big and heavy, costing a lot in freight to ship to us, as well as, requiring special equipment and vehicles to deliver them to customers. We needed to rent extra floor space to inventory the drums, not daring to stack them more than one on top of another. In other words, we rented a lot of wasted air space. Plus disposing of the empty barrels was a problem for customers. Upon learning that the drums of concentrate still contained a lot of water, I mentioned this to Charlie Vollaro, then the owner of Far West Oil. He created a formula that we called “100:1”. One five gallon container of 100:1 produced the same amount of coolant as the typical 55 gallon drum. We found 5 gallon cubetainers, cardboard boxes with a plastic bladder used by the dairy industry. Easy to inventory and ship.
Never went anywhere but we thought it was a good idea, similar to what this article describes about Tide.
