  • Patent number: 5257887
    Abstract: A collection container adapted to be lifted and emptied with a grasping device. The container forms an enclosure with two sections each having a projection and being pivotally connected to each other. The sections are held together with a spring. The container includes an opening to receive objects. The spring tension is set so that the grasping device can lift the container by the projections without the section separating. The projections are angled on the enclosure so that if the grasping device were to squeeze the projections together the two sections would pivotally open and dump the objects in a bin. A trough is coupled to a slot on the container to prevent the container's contents from being pilfered.
