Definitions

  • Another object is to provide a method by which any number of packets within practical limits, may be assembled into a single package and which may be subsequently opened to permit distribution or sale of individual packets while aifording excellent protection for the remaining packets.
  • a further object is to provide a method by which the ,assembly of packets forming a single package, are adapted for palletization and safe expeditious handling, as by a lift truck.
  • a still further object is the provision of a method of packaging in which two individual sheets of protective material such as cardboard, rigid or semi-rigid, are first applied to and over the respective outside faces of a stack or packet of panes to be packaged, and the two sheets ,are subsequently firmly and rigidly united by material which is originally fluid but which rapidly expands and sets into foam encasing and protecting the edges of the packet.
  • Another object is to provide a method as in the preceding paragraph, wherein the sheets of protective material are bound together over the surfaces conjointly formed by the edges of the packet of plates, prior to completion of the package by the application of the expansible and hardenable fluid.
  • Yet another object is the provision of a package for shipping packets of panes of material assembled in faceto-face relation, or groups of such packets, which is relatively light in weight, simple to fabricate, and which affords a high degree of protection to the panes, against damage by breakage, chipping of the edges, moisture, etc.
  • a further object is to provide a package of the type aforesaid, wherein the hardened foam material, at one and the same time, connects the outer protective facing sheets of cardboard or the like, while effectively protecting the edges of the packet or packets of panes.
  • Another object is to provide a package as aforesaid, which is easily opened and, when opened, enables individual panes, or packets to be removed for sale or use while effectively protecting those remaining in the package.
  • FIGURE 1 is .a perspective view of two planar packing elements'or sheets, with a packet of panes emplaced between them, and bound together by strapping, prior to application of the encasing foam material, a corner of one of the sheets being broken away to show the packet of panes;
  • FIGURE 2 is a detail cross section of a wrtion of the completed package, that is, after the encasing foam ma- 3,344,917 Patented Oct. 3, 1967 "Ice terial has been emplaced, as it would appear in a plane identified by line 2-2, FIGURE 1;
  • FIGURE 3 is an exploded perspective view showing how the two facing sheets of cardboard are applied to opposite sides of an assemblage or stack of panes to be packaged, and guided into proper registration with the panes and with each other;
  • FIGURE 4 shows how a number of discrete packets may be assembled into a single unitary package, fixed to a pallet for ease in handling and shipment.
  • panes the individual items to be packaged will be called panes
  • packets the discrete groups of panes
  • sheets the items used to enclose the packet or group of packets.
  • the invention is of particular utility in the packaging of glass, it is equally useful in packaging other sheet materials such as metal plates, tiles, paperboard, wallboard, plastics and many other materials.
  • 1 and 2 identify rigid or semi-rigid sheets of packing material such as card board, corrugated paperboard, etc., in superposed registration and in face-to-face contact with respective outer ones of a stack of panes 3 to be packaged and protected.
  • Sheets 1 and 2 are of greater length and'width than the stack or packet of panes so that when the items are in assembled relation with the panes symmetrically disposed between and with relation to the sheets, there is formed a channel 4 extending about the perimeter of the packet. For example, if the packet has a length of 61 cm., a width of 40 cm., and a thickness of 8.4 cm., and if the sheets 1 and 2 are each 69 cm. long and 48 cm.
  • each longitudinal edge of sheet 1 has two pairs of parallel cuts therein, normal to the edges.
  • the two pairs of cuts in one edge define slots 5 and 6, respectively.
  • the two pairs of cuts define slots 7 and 8 in the other edge.
  • Sheet 2 has similar cuts therein defining slots 9 and 10 along one longitudinal edge, and 11 and 12 along the other longitudinal edge.
  • the tongues such as 13, formed by the cuts defining a slot 10, are turned inwardly.
  • the slots are symmetrically disposed and of a depth which, in the example given, would be 4 cm. for each slot.
  • each pair of slots such as 7 and 10 are in registration and, for example, tongue 13 of slot 10 fits over tongue 14 of slot 7.
  • the tongues thus operate to properly centralize the sheets with respect to the packet and, conversely, the packet of panes fits smoothly between the pairs of tongues.
  • FIGURE 2 shows the assembled arrangement wherein tongue 15 formed by the cuts in sheet 2 and defining slot 12, fits over the edge of the packet, while tongue 16 formed by the cuts defining slot 6 in sheet 1, fits over tongue 15.
  • tongue 15 formed by the cuts in sheet 2 and defining slot 12 fits over the edge of the packet
  • tongue 16 formed by the cuts defining slot 6 in sheet 1 fits over tongue 15.
  • the completely superposed relation of the tongues shown upon FIGURE 2 is not essential and the overlap thereof will depend upon the thickness of the packet, that is, the number of panes therein.
  • the tongues may be in alignment with their ends in contact or spaced an appreciable distance.
  • FIGURE 2 shows the packet enclosed within a protective film 17 of polyethylene which in the figure has an exaggerated thickness and which in actual practice will be of the order of 0.05 mm.
  • slots 5, 6, etc. have a width to receive with a smooth fit, tightenable straps or hands 18 and 19.
  • These bands may be of metal or plastic such as polyvinyl chloride, to provide the double advantage of uniform tension and easy opening of the package by cutting with a pair of scissors. Where the package is large and heavy, metal strapping may be used.
  • Each strap passes in contact with the outer face of each of the sheets 1 and 2 and through the slots therein so that they act to bind the sheets and packet together and at the same time effectively hold the packet of panes centralized with respect to the sheets, maintain the sheets in registration, and prevent shifting of the packet relatively to the sheets.
  • the channel 4 formed conjointly by the packet and sheets, may be filled with polyurethane or other foam material which expands and hardens rapidly and adheres to the sheets without, however, adhering to the polyethylene enclosure 17 of the packet.
  • polyurethane or other foam material which expands and hardens rapidly and adheres to the sheets without, however, adhering to the polyethylene enclosure 17 of the packet.
  • a hardenable phenolic foam may be used instead of the polyurethane.
  • the procedure in filling the channel with protective foam is conveniently carried out in the following manner.
  • the two sheets with a packet of panes enclosed in polyethylene are bound together with straps, by assembly upon a table. In certain cases the straps may be omitted.
  • the channel conjointly formed by the packet and sheets is covered temporarily with a mold.
  • This mold may consist of four strips or lengths of material each corresponding in length with the edges of the sheets to be covered thereby, and of a width overlapping the edges. Where strapping has been used these strips are also formed with side edges which depend and extend over and effectively cover the slots in the edges of the sheets, through which the straps extend.
  • the four lengths forming the mold are conveniently held in place by an encircling band or hoop, or in any other suitable way.
  • the temporary mold may be in the form of a single length or strip of material having a length equal to the perimeter of the sheets, and hinged or articulated at points along its length corresponding to the locations of the corners of the sheets.
  • the ends of this strip are releasably connected together by suitable clasp or hasp means.
  • Each strip or section is formed with sprue holes so that when emplaced about the sheets there will be at least one such hole over each respective one of the four sides or portions of the channel, and through which the liquid foam mix is forced into the channel.
  • the sheets are of corrugated paperboard, consisting of a core of corrugated sheet having flat outer sheets adhesively secured to each side, it may be desira ble to so form the temporary mold that the edges of these sheets are covered with a light covering of the foam so that the openings formed in the edges of the sheets by the corrugated core, are thereby obturated.
  • they may be located in the sheets in position extending over and along the channel filled with hardened foam, that is, between the edges of the packet and the contiguous edges of the sheets. In such a location, after tearing out the strips and removing the portions of the sheets thus separated, the foam material is exposed and readily removed from along the contiguous edge, so that the panes may be re-' moved individually or as a unit.
  • FIGURE 4 shows a package embodying the invention
  • each packet may have its own two sheets bound with straps about an interposed group or packet of panes. In such a construction the foam will flow into and fill the aligned slots between each pair of con tiguous packets and thus form bridges interconnecting them for encasement within a container 27 of conventional form and construction, having a cover 28.
  • a pallet generally identified at 29 comprises a base 30, upper platform '31, and corner blocks 32, 33, '34, etc. rigidly attached to the base and platform and holding them in spaced relation for ready insertion therebetween of the fork of a lift truck. Strapping 35, 36, etc. passes over and about container 27 and its cover 28, and beneath platform 31, to thus rigidly unite the parts.
  • the resin is concentrated to about 72%
  • ingredients 1 through 4 are mixed in the order given and the mixture maintained at a temperature of not over C.
  • ingredient 5 is added and the mixture is violently and rapidly agitated as in the preceding example.
  • the resulting cream-like fluid is quickly introduced into the channels, because the setting time is very brief-on the order of 5 seconds maximum. Expansion and hardening occur as in the previous example.
  • the final density is about the same as in the case of polyurethane.
  • An article of manufacture comprising a flat object to be packaged, first and second sheets of stifi material at like size and shape and of larger transverse dimensions than said object, said sheets being disposed with their edges substantially in registration and with said object between them, with its edges spaced inwardly from the edges of the sheets, to define a channel conjointly with the edge of said object, and a self-hardening material disposed within said channel continuously therealong and adherent to the surfaces of the sheets contacted thereby.
  • each said sheet having a plurality of peripherally-spaced pairs of parallel cuts extending inwardly from its edge, to the edge of said object, to thereby define a plurality of slots, said means comprising a plurality of tensioned straps each encircling said sheets and object, and passing through a respective set of said slots.
  • said sheets having pairs of parallel cuts extending inwardly from their edges, to the edge of said object, to form slots, said means comprising a tensioned strap encircling said sheets and said object, and passing through said slots, inwardly of said self-hardening material.
  • each pair of said parallel cuts also forming a tongue, all said tongues being folded inwardly across the edge of said object and encompassed by said strap to be held thereby in substantially contacting relation with the edge of said object.
  • the method of forming a package encasing a flat object comprising, applying to respective outer faces of the object a respective one of two sheets of stiff packing material each larger than the object, assembling said sheets and object together, with the edges of the sheets projecting outwardly beyond the perimeter of the object, and filling the channel formed conjointly by the projecting edges of the sheets and the edges of the object, with a fluent self-hardening plastic material.
  • plastic material being polyurethane foam.
  • a package comprising a plurality of sets of stacked rectangular plates, a plurality of rectangular sheets of stiff packing material of larger size than said plates, there being at least one said sheet between and separating each contiguous pair of sets of plates, and a respective one of two of said sheets over the outer face of the two outer sets of plates, all said sheets being in registration and projecting outwardly beyond the perimeter of the sets of plates to define therewith a plurality of channels each extending about the perimeter of a respective set of plates, and a self-hardening plastic foam material disposed in a continuous band in and along each said channel and adherent to the surfaces of the sheets contacted thereby.
  • each said sheet having a plurality of pairs of parallel cuts in each edge, each pair of cuts defining a slot, said foam material extending through said slots to interconnect all said bands.
