<p>A pail (12) and lid (30) with an integral handle (31) molded with the lid includes a pail side wall (22) extending upwardly from the pail bottom (26) to an upper peripheral edge (23). The lid includes a cover portion (38) shaped to cover the open top and a peripheral skirt (29) depending from said cover portion, said skirt having an upper annular portion (44) and a lower annular portion (32) and both shaped to surround an outer surface of the pail side wall at or adjacent the upper edge and separated by a peripheral tear strip (45). The handle is integrally formed with said lower portion for carrying the pail. The skirt and pail have co-operating upper (44A, 23A) and lower pairs (32A, 36A) of retaining lips shaped to snap over each other by downward movement of the cover portion onto the pail to hold the cover portion on the pail. The skirt is sufficiently stiff to allow both snap actions to be effected simultaneously be pressure downwardly from the cover. The lower pair provide greater retaining force such that, prior to pulling the tear strip, co-operation of said lower retaining lip of the peripheral skirt and said lower retaining lip of the pail provides a strong force in maintaining the cover portion on the pail and such that, upon tearing, co-operation of said lower retaining lip of the peripheral skirt and said lower retaining lip of the pail substantially prevents upward vertical displacement of said lower portion and the handle thereon relative to said pail so that the handle can accept high loads.</p> |
