ABSTRACT:
A novel basket cover and the combination of the novel cover and a novel basket are disclosed. The basket cover is essentially a dome-shaped article of clear plastic having a straight skirt depending from a dome portion and corners in the skirt having detents which releasably mate with and lock onto corners of the basket. In a preferred embodiment the detent includes a flat triangular section having an apex aligned with the rim of the dome and extending down to an arc-shaped rigde merging with a convex detent, which in turn, extends to the periphery of the skirt. The basket cover is further provided with ribs extending up its sides and presenting perpendicular basket engaging surfaces which engage and hold in place the bottom of a second basket stacked thereon. In the preferred embodiment the basket cover is further provided with vents which are angled with respect to both the flat top of the cover and its sides. With vents of such a configuration, they will be left partially uncovered when another basket is stacked thereon. The basket itself is provided with bottom vents and side corner vents for receiving cooling air which is believed to pass up through the berries or other produce contained within the basket and exit through the vents in the basket cover.
