A thermoplastic container assembly includes an improved means of attachment between lid, base and container which meets paint industry drop test standards and includes tamper evidence, a transparent lid and improved means to prevent leakage between the base, lid and container. The container includes an upper extending tubular wall element extending from the perimeter of a bottom wall to an upper rim, the upper rim including an annular inward facing cavity formed by a reduced thickness area, which includes an annular inward facing upper bead positioned above the inward facing cavity. A base includes an annular portion having an outwardly directed resilient exterior annular wall which engages the inward facing cavity of the rim of the tubular element in snap fit engagement. A lid includes a plurality of spaced apart resilient flange/protrusion elements extending outwardly from a bottom portion of an annular portion of the lid; the flanges/protrusion elements being snap-fit engageable within an upward facing annular groove of the base.
