Definitions

  • Blomstedt ABSTRACT A rectangular carton for storing packages of polymer, which carton is divided by intersecting partitions into four rectangular cells with each cell sized to hold snugly a single stack of such packages. The carton prevents bursting of the packages due to cold flow of the polymer during storage and shipping.
  • Synthetic elastomers such as butadiene/styrene polymers (SBR) and ethylene/propylene/diene polymers (EPDM) are normally stored and shipped in plastic or paper wrappings or bags containing about 34 kg. of polymer each. These packages, when freshly filled, normally have dimensions of about l8X35X70 cm. in the case of SBR and l8X4lX6l cm.
  • a container for storing and shipping packaged materials which are subject to settling, expansion, or cold flow.
  • This container is a rectangular box or carton of cardboard, corrugated paperboard or other suitable, flexible, cheap sheet material, divided by vertical partitions into at least four cells or compartments similar in cross section to and equal in height to the box.
  • the term rectangular as applied herein to a three-dimensional structure such as a box, container or cell, refers to a right parallel piped, that is, a six-sided container with planar faces of which each face is in the form of a rectangle.
  • This box is cheap enough to be discarded after use and is easily made from corrugated paperboard by first folding four sheets of paperboard to fonn four individual tubes or open-ended cells having unifonn rectangular cross sections with edges corresponding to the dimensions of the two largest edges of the packages to be contained therein.
  • the four tubes are then arranged vertically in abutting contact about a central axis to form a four-celled carton in the four quadrants about the axis and having the same overall height and rectangular cross-sectional configuration as the individual cells.
  • the larger external faces of the cells in contact with each other are fastened together, as by rivets or suitable adhesive, and each of the two larger sidewalls of the four-celled carton thus formed, is reinforced by covering with an adhering sheet of material.
  • the individual cells can be made with fold tabs or flaps at one end or both as desired to permit closing of one or both ends of each cell in the same manner as a conventional corrugated paperboard box or shipping container.
  • flaps contribute strength and rigidity to the structure.
  • one end of each of the cells does have these end flaps and in assembling the four tubes to form a carton these are placed to form the bottom of the carton.
  • the bottom of the carton is then capped by a removable tray of paperboard having sidewalls which extend up the outside walls of the carton preferably at least percent of the height but in any event sufficiently to provide close-fitting support for the base of the carton and part of the walls.
  • each cell of the carton is of a size to receive a seven-bag stack of polymer laid face to face; the face of the bag being the largest flat surface thereof.
  • the cross section of the cell be of suffrcient size to permit insertion of the bags with reasonable ease but yet small enough to provide a sufficiently snug fit so that the expansion of the bags due to cold flow of polymer is restrained at least to the extent of preventing bursting of the bags.
  • FIG. 1 shows a sheet of cardboard ll creased and folded preparatory to forming the rectangular tube of FIG. 2 having taped joint 15 which bisects one face of the tube, although it can be closer to either side as desired.
  • the tube is made with end flaps 12.
  • Four such tubes are made and assembled to produce the four-celled carton shown in FIG. 3, adhesive first being applied to the larger contacting outside faces 13 of the tubes so that these faces will be adhered to each other.
  • Other fastening means can also be used and it is not necessary that the faces be fastened over their entire contacting area.
  • FIG. 5 shows how such a fourcelled carton with end flaps can be collapsed for shipping or storage without excessive use of space.
  • FIG. 5 shows the unit partially collapsed and FIG. 6 in a more completely collapsed state.
  • the arrangement of the four cells and the manner of fastening them together pennits the carton to be readily collapsed for storage and shipping and, being in one piece except for top and bottom, can be readily set up.
  • the carton can be collapsed completely until its thickness is merely that of the layers of sheet material present.
  • FIG. 7 shows a sheet of cardboard creased and ready for folding to form a top or bottom cover for capping the four-celled carton.
  • top nor bottom of the carton need be adhered, riveted, or otherwise fastened to the body of the carton although normally, prior to shipping, the top and bottom are strapped to the box by conventional shipping straps.
  • any suitable sheet material can be utilized to make the container of the present invention but corrugated cardboard or paperboard are eminently suitable and probably is the cheapest practical type of material for this use. Any sheet material which can be folded as indicated and has sufficient rigidity to provide the necessary support can be used. Films and fabrics of synthetic and natural sheet materials can be used if desired for all or part of the structure depending upon the particular efi'ect desired. Similarly any suitable adhesive can be used so long as the desired strength is provided. Adhesive is normally applied only to cover sheets 14 and to the external large contacting faces of the conduits during assembly but when greater strength is desired adhesives may also be applied to the smaller contacting faces of the tubes during their assembly if collapse of the structure is not necessary prior to use. Also the top and bottom covers of the carton may be adhered to the body portion to provide greater strength but this has not been found to be necessary for normal usage.
  • any convenient fastening means can be used including staples, rivets, or interlocking structures built into or added to the walls to be attached.
  • a carton such as described was constructed entirely of 158 kg. double-wall corrugated paperboard. After folding in the bottom flaps and capping the bottom with a paperboard tray as described, each cell was loaded with 238 kg. of 40 Mooney polymer, the polymer being in polyethylene bags each containing 34 kg. of polymer. Thus there was a stack of seven bags of polymer in each cell. The filled carton was capped with a top cover and a rectangular wood pallet holding four stacks of bagged polymer weighing a total of 1,035 kg. was placed on top of the filled carton.
  • the container was stored in a warehouse at about 23 C. for about 20 days and then shipped a distance of 1,800 miles by truck under the same conditions. It was found that the filled carton and the individual bags of polymer within it were held in practically their original shape by the carton and were in good condition showing very little evidence of deformation. A similar carton tested under the same conditions was equally successful in preventing bag damage.
  • a lightweight carton for storing and shipping packaged materials which are subject to settling or flow comprising a. four rectangular cells assembled in abutting relationship in the quadrants about a central vertical axis to form a four-celled carton having the same rectangular cross-sectional configuration and height as the individual cells,
  • top and bottom of the carton being capped by removable covers which extend partially down the outer walls of the carton.
  • a four-compartment container assembly comprising four tubular container subassemblies each of rectangular cross section each having two side panels and two end panels with said panels carrying bottom-forming flaps;
  • first and second pairs being arranged to form an array in which end panels of the subassemblies of one pair are in adjacent opposed relation to end panels of the subassemblies of the other pair with the subassemblies of one pair in longitudinal alignment with the subassemblies of the other pair;
  • the adjacent and facing end panels of the container subassemblies being unattached and capable of being separated to form a diamond'shaped configuration and the opposite exposed subassembly end panels forming an angular configuration with the apices of the configuration extending outwardl from the center of the assembly as said reinforcing pane s are moved toward each other to collapse said four-compai1ment container and provide a substantially flat contour for the collapsed container.
