A modular cooler that is made of individually insulated modular cooler compartment units that can be stacked together to make a custom sized cooler for any occasion needed. The basic unit is a cylindrical bottom container having specific interlocking structure on its top edge. A tubular compartment unit having mating interlocking structure on its bottom edge is detachably engaged with the interlocking structure of the bottom container unit. A locking ring surrounds both of these interlocking structures and by rotating it a short predetermined distance the two units can be locked together or unlocked. One form of locking ring has a solid central wall that forms it into a compartment divider. Additional units can be stacked together by using additional tubular compartment units and locking rings. A disc-shaped top cover has interlocking structure on its bottom edge. O-rings are positioned between the interlocking structures to make the adjacent compartment watertight and airtight.

An insulated modular cooler comprising: a cylindrical bottom container unit having an annular side wall that has a top edge and a bottom edge, said bottom edge being connected to a bottom wall that closes the bottom end of said container; said top edge of said bottom container having a predetermined thickness from its inner edge to its outer edge, an annular ridge extends upwardly a predetermined height from said top edge; said top edge of said bottom container having a relieved area adjacent its outer edge in the shape of a horizontally oriented annular channel that forms a horizontally oriented upper flange; a locking ring having a horizontally oriented U-shaped cross section having an annular vertical portion with inwardly extending upper and lower annular flanges, said lower annular flange interlockingly mating with the horizontally oriented annular channel at the top edge of said bottom container, said upper annular flange having arcuate cutout portions spaced at predetermined intervals around its inner edge; and a disc-shaped top cover whose bottom edge has an annular channel that matingly interlocks with the annular ridge on the top edge of said bottom container, the bottom surface of said top cover also having a relieved area adjacent its outer edge in the shape of a horizontally oriented annular channel that forms a horizontally oriented graduated lower flange, said graduated lower flange having relieved arcuate sections at predetermined intervals around its outer edge so that said flange can mate with arcuate cutout portions on the top surface of said bottom container, after which said locking ring can be rotated a predetermined distance to lock said two members together.
