Abstract
Abstract A container structure including a container body having an endless rim which defines an open top and having a lid which is demountably attached to the container body by at least a pair of relatively small spaced apart latching lugs. The latching lugs extend inwardly from a depending lip provided on the lid and releasably grip the rim of the container body in a manner which provides and maintains a laterally spaced relationship between the rim of the container body and the inner surface of the depending lip of the lid to facilitate removal and reinstallation of the lid by minimizing frictional engagement between the lid and the container body.
