Container (10) has a rim (16) on a wall, integral flange (19, 20, 21) extending out from the wall below the rim, and the flange has a plurality of openings or recesses (72). Closure (11) has a central portion (14) and an integrally formed skirt (26, 29, 31). A plurality of projections or tabs (70) each extending form the skirt and insertable into a respective opening in the flange. A portion (74, 94) of that projection is caused to assume an orientation by a corresponding formation (85, 100, 101) of the flange, or alternatively a portion (81) of the flange is caused to assume an orientation by a corresponding aperture formation (73) of the projection; such that removal of projection form the opening is resisted until the frangible connection is broken. The lid is securely fastened against removal as a result of dropping, knocking or bumping.
