A wastebasket (10) includes a base portion (11) with an open upper end and a cover (12) pivotally attached thereto.

When used with a plastic liner (53), the liner (53) may be draped over the upper open edge of the base portion (11). Fins (54) carried by the cover (12) travel in trackways (18) located at the upper edge of base portion (11) during the pivotal movement of the cover (12) to push the liner (53) away from the track (39) and pin member (35) so that the liner (53)…
