Abstract: A nest-or-stack, lidless, open-stacking container for handling and storage of bulk material such as food products features a seamless, one piece plastic construction with channels formed into the bottom to permit the use of a forklift truck for moving, lifting and stacking of the container, and with stacking surfaces for stacking filled containers and nesting stop surfaces for nesting empty containers.

Abstract: A light weight heavy duty, inexpensive and portable stackable assembly for storing and dispensing flowable materials such as capsules and other drug products includes a plastic hopper bin and a plastic base, the surfaces of both hopper and base being smooth, having minimal tendency for the adherence of bacteria, and being easily cleaned. The base construction provides a relatively large area of support for the hopper thus eliminating or minimizing any tendency for the hopper walls to sag and to cause unevenness in the hopper inner surface that could interfere with the flow of the flowable materials out the discharge outlet of the hopper. The assembly is characterized that when stacked the weight of the stack is carried by the base, each of the hoppers being required to support the weight only of its own contents.

Abstract: An integral double-wall container, made of a synthetic plastic, for handling bulk materials such as liquids and powder, and adapted to be lifted and moved by means of a forklift truck. An integral one-piece double-wall hopper bin for dispensing liquid and powder. A method of making integral double-wall containers and hopper bins by rotational molding.

Abstract: A hinged knock-down returnable, self-locking bin includes a base panel, first and second side panels, first and second end panels, and first and second panel hinge means, the first panel hinge means being provided for hingedly connecting each of the side panels to a side of the base panel, and the second hinged means being provided for hingedly connecting each of the end panels to an end of the base panel. Locking meansare provided for connecting the tops of the side panels to the tops of the end panels. The bin is characterized by its simplicity of structure, the ease with which it may be erected for use in shipment, singly or in stacked interlocking relation, and the ease with which it may be collapsed so as to occupy a minimum space for storage and return shipment for further use when emptied of its contents.

Abstract: A pallet assembly combines a structurally simple, although relatively expensive, heavy-duty, high quality pallet with an expendable, inexpensive, light-weight, and extraordinarily simple shipper skid. The heavy-duty pallet is made of solid hardwood lumber or other durable material such as plastic and is designed for long lasting service. The expendable shipper skid is made of a light-weight hardwood, plastic or corrugated fiberboard. The pallet assembly is entered by a forklift from one direction and the shipper skid and a load thereon is arranged to be lifted from the pallet assembly by a forklift entering from a direction displaced 90.degree. from said first mentioned direction. Notches in the intermediate as well as the end runners of the heavy-duty pallet allow the tines of the forklift to pass through the entire pallet assembly when the expendable shipper skid is to be lifted. Only the inexpensive expendable shipper skid is shipped with the load.

Abstract: A nestable plastic container for handling and storage of bulk material such as food products is provided with three parallel, laterally spaced, downwardly extending hollow ridges forming supporting members. These ridges permit the use of a fork lift to handle the container. The ridges are hollow and open to the interior of the container but they may be easily cleaned by reason of the fact that they extend substantially the full length of the bottom of the container, and also by reason of the fact that they have a trapezoidal cross-section for easy access to their interiors. Specially designed ridges on the cover of the container receive one of the downwardly extending ridges of another container securing it against lateral motion, and thereby permitting safe stacking of multiple containers.
