Abstract
Abstract The present invention is directed to a device to hold open for loading a limp plastic sack having a body portion terminating in a base and a pair of integral handles. It comprises a horizontally disposed base member; a pair of oppositely-disposed, upwardly-projecting side wall members, each of which is attached at its lower end to the base member; an upwardly projecting rear wall member, wherein each vertical edge of the rear wall member is attached to a vertical edge of each of the side wall members; and means to engage the handles of the plastic sack. These means comprise a pair of spaced-apart ears projecting above the upper edges of each of the side wall members, wherein the space between the ears extends downwardly into each of the side wall members. The space between the ears, including the downward extension thereof, is of sufficient width to permit the insertion of several human fingers therein. Preferably, the height of each side wall member is slightly smaller than the height of the plastic sack to be loaded therein, and the internal perimeter of the base member is at least equal to or slightly greater than the perimeter of the base of the plastic sack when the sack is in an open position ready for loading.
