  • This invention relates generally to the art of fabricating cardboard shipping containers, particularly shipping containers of the kind disclosed in co-pending application Ser. No. 336,970, filed Jan. 10, 1964, now Patent No. 3,197,108 and entitled Container With G'lued Cardboard Stacking Cleats.
  • the invention has more particular reference to a method of and means for mating the separate preformed end panels and blank which make up the shipping container of said co-pending application and erecting or folding the blank about and joining the blank to said panels in such manner as to form a container structure of the kind disclosed in said co-pending application.
  • each container in a vertical column of stacked containers must ⁇ be sufficiently strong to support the vertical load imposed thereon by the upper containers and, in addition, must provide a stable supporting base for the adjacent upper container.
  • Some shipping containers are suiiiciently strong and their top and bottom surfaces are sufciently flat to permit the containers to -be stacked with the bottom surface of one container resting directly on the top surface of the adjacent lower container.
  • the top and/or bottom surfaces of many shipping containers tend to bulge outwardly when the containers are filled.
  • each container can rock back and forth relative to its adjacent lower container, thereby resulting in an extremely unstable and unsafe container stack.
  • Other containers do not possess the required strength to enable them to be stacked one n top of the other, at least to the height necessary for Optimum utilization of a given storage space.
  • the Bliss container in its simplest form, is fabricated from a single cardboard ice a so-called bottom sealing operation, to a partially com- ⁇ pleted condition wherein t-he cover panels are left unfolded to permit the container to Ibe filled. After filling, the container is completed in a so-called top sealing operation during which the cover panels are folded and sealed to close the top of the container. Numerous varia,
  • Bliss containers While the Bliss containers have been and are currently being successfully used for many purposes, they are decient for the reason that they often cannot be stacked to the height required by many warehousing and shipping facilities. This is due to the fact that the containers d0 not possess the requisite structural strength and to the additional fact that the top and bottom surfaces of the containers, when filled, tend to bulge outwardly. As noted above, this bulging of each container prevents the latter from providing a stable support for a container resting thereon.
  • the Bliss containers are also deficient in that when exposed to conditions of high humidity, such as are encountered in commercial freezers and refrigerators, the cardboard material of the containers becomes weakened to the point that the containers collapse.
  • Containers of the kind under discussion are often used to ship produce.
  • the containers are provided with ventilation openings to permit the free circulation of air through the containers.
  • Many produce containers are not constructed to preserve such ventilation spaces ybetween adjacent containers in a container stack.
  • stacking cleats comprise flatA strips which are secured to the top and/or bottom of aV container adjacent its ends to provide at supporting sur faces for an adjacent upper container in a column of stacked containers.
  • stacking cleats space the confronting top and bottom surfaces of adjacent stacked containers to provide ventilation passages therebetween.
  • the aforementioned co-pending application Serial No. 336,970 discloses a shipping container which successfully avoids the above discussed defects of the currently available s-hipping containers.
  • the container of said co-pending application is fabricated from a preformed cardboard blank and two separate preformed end wall forming panels, or end panels as they will be referred to herein.
  • the blank is scored and perforated to form a number of longitudinal and transverse hinge lines which define on the blank a central bottom wall forming panel, two side wall forming panels outboard the bottom wall forming panel, two cover forming panels outboard of the side wall forming panels, and end panel joining flaps along opposite side edges of the bottom wall forming panel -and the two side wall forming panels.
  • the two separate end panels have a laminated construction including a wooden core and a cardboard p-anel bonded to the outer surface of the core in such manner that the upper edgey portion of the cardboard panel projects a distance above the upper edge of the wooden core to define a hinged flap.
  • the end panels are mated with the blank by engaging the lower edges of the panels with the central bottom wall forming panel of the blank just inboard of the hinge lines of the iiaps on the latter panel. Thereafter, the side wall forming panels of the blank are folded upwardly about opposite ends of the end panels, the iiaps on the blank are folded inwardly against the outer surfaces of the end panels, the cover forming panels are folded inwardly across the top of the container, and, nally, the projecting flaps on the end wall forming panels are folded inwardly over the folded cover forming panels.
  • the several folded end panel joining iaps on the blank are adhesively bonded to the outer surfaces of the end panels, and the folded aps on the end panels are adhesively bonded to the folded cover forming panels, thereby to form a completed container.
  • the container is initially formed, in a bottom sealing operation, to a partially completed condition, wherein the cover forming panels and the aps on the end panels are left unfolded to permit the container to be lled. Thereafter, the cover forming panels and end panel flaps are folded and sealed in a top sealing operation to complete the container.
  • the folded end panel aps overlie the cover forming panels to define cardboard stacking cleats which are reinforced by the wooden cores of the end panels. It has been found that the improved shipping container of the co-pending application is uniquely capable of satisfying both the stacking and ventilation -requirements referred to earlier.
  • a more specific object of the invention is to provide a container forming method and machine of the character described wherein a pair of end panels are mated with a preformed blank and thereafter the side wall forming panels of the blank are folded upwardly about opposite ends of the end panels and the end panel joining flaps on the blank are folded inwardly against and adhesively bonded to the outer surfaces of the end panels to form a partially completed container structure.
  • Another object of the invention is to provide a container forming machine of the character described which is fully automatic in operation.
  • a further object of the invention is to provide a container forming machine of the character described which may be adjusted to accommodate container blanks and end panels of different sizes.
  • Yet a further object of the invention is to provide a container forming machine of the character described which is relatively compact, reliable in operation, easy to use, c-apable of high speed operation, and is otherwise ideally suited to its intended purposes.
