Definitions

  • This invention relates generally to containers for packaging relatively fragile articles such as eggs or the like, and is more particularly directed to improvements in the cover of a container and the manner in which the cover cooperates with a cellular tray.
  • the packaging containers of the present invention may be produced from various suitable packaging materials which include, by way of example, pulp and plastics.
  • Producing the packaging container of molded pulp the suction forming process may be utilized wherein the pulp fibers are sucked from a slurry of fibers onto a shaped screen.
  • Plastics such as thermoplastics, may be injection molded. Extruded sheets of thermoplastic may be vacuum formed.
  • Foam thermoplastics may be utilized and molded into packaging containers of the present invention by extruding a foam sheet which is then vacuum formed into shape.
  • Packaging of fragile articles involves the balancing of factors which include the amount of structure which goes toward the functional protection of the articles and the amount of material utilized which has to do with the economics of packaging.
  • Economic considerations involve presenting the packaged articles in a manner to their most salable advantage and containing the packaged articles with the greatest amount of protection in proportion to the quantity of material utilized in the container and so fashioning the container so that its manufacture can be effected in an eflicient and facile way.
  • Qbjects of the present invention include: To provide an improved container including a tray and cover which utilizes the container cover structure in relation to the tray to such an advantage as to materially enhance the normal protection afforded by physical characteristics of the material from which the container is produced; to utilize structural formations in a container to such advantage that the strength per unit of material is increased to provide a container which minimizes article breaking, yet preserves the articles at optimum accessibility for removal from the container; to provide a container having a cover essentially incorporating structural beams or channels which protectively pocket or enclose upper portions of fragile articles disposed in a cellular tray of the container; to provide a container having a cover essentially incorporating structural beams which include structure protectively pocketing upper ends of fragile articles and including structure whereby egg rattle is substantially inhibited in all directions; to provide a container having structural beams of the character mentioned above and in which
