摘要： A waste receptacle (10) includes a generally cylindrical base container portion (12) having a generally circular open top (15) and a generally circular cover (11) for closing the open top (15). A plurality of circumferentially spaced lug members (24) extend radially outwardly from an upper skirt (17) of the base container and include nubs (26) extending downwardly from the circumferential ends thereof. The cover (11) has a lower skirt (32) with inwardly directed locking lugs (35) circumferentially spaced thereon, the spacing being generally the same as the spacing of the lug members (24). The cover (11) is placed on the base container portion (12) with its locking lugs (35) not aligned with the lug members (24) of the base container portion (12). Then upon rotation of the cover (11), its locking lugs (35) will first engage the nubs (26) of the lug members (24) of the base container portion (12) and upon further rotation, the locking lugs (35) will be positioned under each of the lug members (24) and between the nubs (26) thereof to lock the cover (11) onto the base container portion (12).
