Definitions

  • This invention relates to totes and more particularly to totes made from foldable blanks with components to hold the blanks in an erected, assembled relationship for stacking.
  • a wide variety of container structures are used by manufacturers to store and ship a variety of different products.
  • an assembly plant assembling a particular automobile might use a number of different parts from different manufacturers.
  • These manufacturers ship their respective parts to the assembly plant in containers where the parts are then removed from the containers and assembled into a finished automobile.
  • the containers are also used to store or transport the various parts within the assembly plant.
  • Containers are useful for the transportation, storage, and display of goods in manufacturing facilities. Such containers, commonly called totes, must be of sufficiently rigid construction to enable safe and damage free transport and storage of the goods contained therein. These totes are frequently designed so as to be stacked or mounted in a nesting relation for convenient transportation or storage.
  • This invention is directed to a tote which is assembled from at least one box blank, a base and a top rail. When folded into the appropriate shape, the blank results in the side walls of the tote.
  • a single blank may be used alone or in combination with other blanks for the tote.
  • the blanks may be corrugated plastic, paperboard or other suitable material and may be die cut to the appropriate configuration and desired height.
  • a channel shaped top rail extends around the top edge of the blanks and a base is mounted to the bottom edge of the blanks.
  • the base and top rail both have an open channel formed between a pair of channel walls.
  • the base and top rail are each, in certain embodiments, manufactured from a single piece of extruded plastic or aluminum and may be injection molded. Alternatively, the base and top rail may each be constructed of multiple pieces of material welded or otherwise joined together. The inwardly extending hooks or ledges on the channel wall engage the folded tab on the sidewalls thereby securing the top rail and base onto the edges of the sidewalls without the need for further fasteners such as screws, rivets, or staples.
  • the configuration of the top rail and base enables nested stacking of additional totes.
  • the base of each tote has a configuration which mates with the top rail to facilitate stacking.
  • This invention provides a container which is lightweight enough that a worker may be able to easily move the container even when it is filled.
  • Another advantage of this invention is that a stackable container of a desired size may be manufactured more quickly and less expensively than is presently possible with other such containers.
  • the top rail or the base or both may be secured to the sidewalls with a plurality of locking members engaged with the sidewalls at select locations, i.e. where there are openings in the sidewalls of the tote.
  • one or multiple blanks may each be folded to form the sidewalls of the tote container.
  • Each locking member may be a clip or other similar structure which may function in a similar manner to the tabs of the other embodiments described herein.
  • the top rail of the tote provides a generally horizontal stacking surface, inside which the base of another tote container made in accordance with the present invention may be quickly and easily nested for stacking purposes.
