ABSTRACT:
A semi-automated apparatus and method for filling a basket with loose, fresh spinach and ice, compacting the spinach into the volume of the basket and retaining the spinach within the basket until a cover is secured thereon. The spinach and ice are gravity fed through a hopper and hollow, cylindrical guide, and a plunger is lowered through the guide to compress the spinach into an open basket directly below. The plunger face is grooved to accommodate a plurality of rods which are axially (longitudinally) advanced through the grooves and serve to hold the spinach in the basket as the plunger is retracted. The filled basket, with the retaining rods in place, is moved to a position laterally of the guide and a cover is secured in the usual manner by placing the wire basket handles over tabs extending from the circular cover. The rods are then axially retracted from between the spinach and basket cover. A laterally movable carriage holding two baskets is provided to allow a full basket to be covered, removed and replaced by an empty basket as another basket is being filled.
