Abstract
Abstract A container having a body and a tamper-evident band and a lid for closing the container. The band has a proximal portion frangibly attached to the container body and a distal portion. The distal portion of the band is deformable to an inward extending orientation with the distal portion shaped and positioned to extend inwardly across the peripheral outer portion of a lid. The deformed distal portion of the band optionally has a curvature of 90° to 360° or more. The lid optionally has an annular groove for concealing the terminus of the band. The lid may also have an outward extending peripheral flange, an upward extending annular rib and a stacking ring for arranging several lids in a nested stack.
