Description

    Technical Field
  • The present invention relates, in general, to packaging and, in particular, to a paperboard packing container for lengthy articles.
    • Background Art
  • Various constructions have been used in the past to package lengthy articles. One such construction includes a pair of corrugated paperboard top and bottom U-shaped channels arranged for one to fit within the other with end caps fitted into the open ends of the assembly of the U-shaped channels.
  • One major shortcoming in using corrugated paperboard as the packaging material for long packing containers is inadequate strength and stability, particularly when the articles being packed are heavy. Another problem is with the assembly of the containers. Corrugated paperboard blanks with scored fold lines which are folded into U-channels, five panel, or fan fold folders are awkward to handle, as they are assembled into containers, because they do not keep their assembled shape. It is apparent that this problem becomes more pronounced the longer the packing container.
  • Another packing construction currently in use is preformed round paper tubes. Among the problems with such containers are that they must be end-loaded and because they are circular, they roll around and stacking is, at best, difficult.
  • Wooden crates also are used as packing containers at the present time. Besides being expensive, wooden crates are heavy, making handling difficult and adding to shipping costs. In addition, because wooden crates cannot be recycled, disposal is a problem.
  • Document US-A 3,669,338 from which the preamble of claim 1 starts discloses a packing container comprising a base unit having a floor (bottom) portion and opposed side walls and a cover unit having a top portion and opposed side walls, both of them substantially having U-shaped configuration (see claim 1 as well as the paragraph bridging columns 1 and 2). However, these containers are fabricated from sheets of flat, flexible sheet material having specific fold lines so that the parts of the container may be folded into the required position for forming a container (see column 2, line 69, to column 3, line 17).
  • The same applies, mutatis mutandis, to the packing container disclosed in FR-A 2,498,561 . Claim 1 as well as the specification on pages 2 and 3 disclose packing containers being assembled from flat sheets by folding along weakened fold lines or hinges; see, in particular, Figures 1, 5 and 6 together with the corresponding description on pages 5 and 6.
  • EP-A 0 020 171 also describes reusable packing containers which are, however, made of card board (see claim 1 as well as page 1, lines 16 to 24 as well as pages 5, lines 11 et seq.). The container described here has also the disadvantage to lack longitudinal rigidity, because the walls of the container components are joined along weakend, i. e. scored or hinged fold lines to permit the desired formation when being assembled.
  • Document AU-A 14,545 is also directed to packing containers. Again, these containers are made of a material providing limited strength as a result of the material (cardboard) which is folded along fold lines or hinges.
    • Disclosure of the Invention
  • Accordingly, a packing container, constructed in accordance with the present invention and defined by claim 1 is suggested.
  • In one embodiment of the invention, the end caps are separate components preferably formed of laminated paperboard and having a U-shaped cross-section. In another embodiment of the invention, the sidewalls of the cover unit are notched near their ends and the end caps are end sections of the cover unit folded downward at the notches in the sidewalls. In a third embodiment of the invention, the cover unit is shorter than the base unit and each end cap is integral with and folded down from a section which is fitted over the base unit.
    • Brief Description of the Drawings
  • Referring to the drawings:
    • Figure 1 is an exploded, perspective view of a first embodiment of a packing container constructed in accordance with the present invention;
    • Figure 2 is a cross-section view of any of the U-shaped components of Figure 1;
    • Figure 3 is a perspective view of the Figure 1 base unit and cover unit after assembly with solid end caps substituted for the Figure 1 end caps;
    • Figure 4 is a perspective view of a second embodiment of a packing container constructed in accordance with the present invention; and
    • Figure 5 is a perspective view of the top unit of Figure 4 inverted.
    Best Modes of Carrying out the Invention
  • Referring to Figures 1, 2 and 3, a packing container, constructed in accordance with the present invention, includes a base unit 10 formed of laminated paperboard and having a bottom portion 10a and opposed sidewalls 10b and 10c, to form a laminated U-shaped cross-section. Also included is a cover unit 12 formed of laminated paperboard and having a top portion 12a and opposed sidewalls 12b and 12c to form a laminated U-shaped cross-section. Base unit 10 and cover unit 12 are sized so that upon assembly into a container, as illustrated in Figure 3, the upper edges of the outside surfaces of sidewalls 10b and 10c of base unit 10 fit within and embrace sidewalls 12b and 12c, respectively, of cover unit 12.
  • The packing container shown in Figures 1 and 3 further includes a pair of end caps which close off opposite open ends of the container formed when base unit 10 and cover unit 12 are assembled as a container. In Figure 1, each end cap 14 is formed of laminated paperboard and includes a base portion 14a and two opposed sidewalls 14b and 14c to form a laminated U-shaped cross-section. Base portion 14a and sidewalls 14b and 14c extend between bottom portion 10a of base unit 10 and top portion 12a of cover unit 12.
  • End caps 14 are inserted in the opposite open ends of the assembly of base unit 10 and cover unit 12 with base portions 14a of the end caps inward of sidewalls 14b and 14c relative to the open ends of the assembly. In this way, the three layers of laminated paperboard material at each corner of the packing container, namely a sidewall of base unit 10, a sidewall of cover unit 12, and a sidewall of an end cap 14, can be stapled to secure together the components of the packing container.
  • Conventional bands 16 can be used to tie together base unit 10 and cover unit 12 at selected points along the length of the packing container. In the alternative, base unit 10, cover unit 12 and end caps 14 can be glued together as they are assembled into the packing container.
  • Figure 2, showing a laminated paperboard formed into a laminated U-shaped cross-section, can represent the cross-sections of base unit 10, cover unit 12 or end caps 14. Those skilled in the art of manufacturing packaging container components will appreciate that by forming all four components, namely base unit 10, cover unit 12, and end caps 14 as U-shaped members made from the same laminated paperboard material, the same machine can be used to produce these parts but with different dies to form the three differently sized U-shaped members. However, it is understood that other components can be employed as end caps. For example, as illustrated in Figure 3, the end caps can be solid members, such as a block 18, made from wood or styrofoam, which is held in place by suitable means, such as by glue or bands tightly wrapped around the ends of base unit 10 and cover unit 12.
  • Figures 4 and 5 show a second embodiment of a packing container constructed in accordance with the present invention. This embodiment differs from the first embodiment in that the cover unit and the end caps are arranged to form mitered corners. In one version of this embodiment of the invention, end caps 20 are integral with cover unit 22 and are end sections of the cover unit which extend downward from top portion 22a of the cover unit when folded into place along fold lines 23 to form the packing container. Sidewalls 22b and 22c have V-notches 24 spaced inward from the ends of cover unit 22 by a distance equal to the distance between top portion 22a of the cover unit and bottom portion 10a of base unit 10. V-notches 24, having a 90° included angle, extend to the junctions of sidewalls 22b and 22c with top portion 22a. With cover unit 22 and base unit 10 assembled, end caps 22 are folded downward, as indicated by an arrow 26, along fold lines 23 to close off the opposite open ends of the container as indicated at the right-hand end of the container of Figure 4. In this position, the sidewalls of end sections of cover unit 22 outward of V-notches 24 embrace the end edges of the outside surfaces of the sidewalls of base unit 10. End caps 20 can be held in place by suitable means, such as by glue or bands tightly wrapped around the ends of base unit 10 and cover unit 22. As with the Figures 1 and 3 embodiment of the invention, bands 16 can be used to tie together base unit 10 and cover unit 22 or these parts can be glued together as they are assembled into the packing container.
  • Instead of fabricating the cover unit and the end caps as a single component with notched sidewalls, the end caps and the cover unit can be fabricated as separate components. When fabricated in this way, both ends of the sidewalls of the cover unit are cut at an angle and one end of the sidewalls of each of the end caps are cut at an angle, whereby two mitered corners are formed by the cover unit and the end caps.
  • In yet another version of the Figures 4 and 5 embodiment of the present invention, the cover unit is shorter than the base unit. This is represented by the dashed lines in Figure 5 identified by reference numerals 26. With a shorter cover unit, the container includes a pair of end members 28 of U-shaped cross-section at opposite ends of the base unit. Each end member 28 has V-notches 24 in its sidewalls with a first length to one side of the V-notches fitted over the base unit with its sidewalls embracing the upper edges of the outside surfaces of the sidewalls of the base unit. A second length of each end member 28 to the other side of V-notches 24 is folded downward with its sidewalls embracing the end edges of the outside surfaces of the sidewalls of the base unit. Each end member 28 is sized so that with the first length abutting against the cover unit, it extends to the end of the base unit. The second length of each end member extends downward to the bottom portion of the base unit.
  • While in the foregoing there have been described preferred embodiments of the present invention, it should be understood to those skilled in the art that various modifications and changes can be made without departing from the true spirit and scope of the invention as recited in the claims.
