A tamper-evident plastic canister, plastic reclosure lid and shrink band assembly comprised of: (a) a circular, molded thermoplastic straight-walled canister which terminates at its upper, open end with a circular rim and which terminates at its bottom end with an inwardly stepped profile which is connected to a circular base, said base having a depressed, circular center and an outer annular ring which ring forms the most bottom surface of the canister, said annular ring having inner and outer diameters similar, but slightly smaller than a generally U-shaped, annular channel depressed in the top surface of a matched reclosure lid, and said canister having a peripheral ridge located at or near the top of the canister which ridge extends outwardly from the canister wall; (b) a one-piece, non-segmented, molded, flexible, thermoplastic reclosure lid having a continuous, depending skirt and an inverted U-shaped upstanding rim around the lid periphery, said rim being comprised of inner and outer side walls, a horizontal top wall and an internal channel which is sized smaller than the thickness of the rim of the canister and which co-acts therewith to form a hermetic wedge seal upon application of lid onto the cannister rim; (c) said lid skirt shaped to receive and secure itself to the container rim by means of an integral and inwardly-extending circular ring which co-acts to form a lock with the peripheral ridge of the canister and wherein said outer skirt wall terminates at its bottom end with an outwardly-flared section sized to exceed the outer diameter of the canister rim and the canister peripheral ridge, said flared portion forming a guide to aid in mating the canister and lid; (d) said inner wall of the U-shaped, upstanding rim being sized slightly larger than the outer diameter of the annular ring which forms the bottom surface of the canister in order to provide a primary nesting means when stacking lidded canisters; (e) said lid containing on its upper surface a shoulder which provides a secondary nesting means to co-act with the canister bottom, said secondary nesting means being comprised of a raised, circular, horizontal, central area, which area is at a height slightly above the top of the U-shaped rim, and a horizontal, or downwardly sloping transition section connecting the inner wall of the U-shaped upstanding rim and said shoulder and wherein said raised central area is sized to be slightly smaller in diameter than the inner diameter of the annular ring which forms the bottom surface of the canister; and (f) a circular shrink band which is shrunk to engage the depending skirt of the plastic lid, including said outwardly-flared section, and the side wall of the canister such that the reclosure lid cannot be removed from and replaced on the canister without evidencing visible signs of tampering, said shrink band being positioned so as not to extend above or over the horizontal top wall of the U-shaped rim.
