This item may be very familiar to some UKand Commonwealth forum members but perhaps less familiar to some of our US forum members, an SRD Jar, commonly known as a Rum Jar. These were in common use from at least the WW1 period until after WW2 and well into the 1950's, at least. This particular example has an uncommon and I believe original style of metal handle attached. Although often referred to as "Rum Jars" they could also be used for any liquid and of course once empty were recycled. I assume that they were only used for liquids intended for human consumption. As I understand it the ones in Royal Navy use were encased in a wicker type basket.
