Definitions

  • the present invention relates to containers and, more particularly, to the formation and construction of an improved container of the type having an end member formed of a plurality of laminations of fibrous material.
  • the invention is concerned with an improved end connection between the body and end ⁇ walls of a fibrous shipping container, and to methods of manufacture thereof.
  • non-metallic shipping containers having an endmemberor closure comprising a disc formed of fiber, plywood, or similar material, with the disc being attached to the containerbody wall by means of a pair of axially spaced, inwardly extending, circumferential ribs formed in the body wall in confining re- On cnated fibrous disc in Which the different 'laminations have identical diameters substantially equ-al to the internal ⁇ diameter of the body wall, thus permitting the end member to lseat on one of the ribs or shelves formed in the body wall and to be held in place thereon by the other
  • the end member does not contribute in any iway to the strength of the connection between the end member and the body wall.
  • the main disc that is, the disc which contributes most to the thickness of the end member
  • the main disc is normally the disc having the smallest diameter with the particular diameter selected being equal to or slightly less than the internal diameter of the body iwall.
  • the remaining disc or discs have a greater diam- United States Patent ice veter than either the main disc or the body wall, and the vit is held in place by only the relatively weak peripheral edges of the layers having the larger diameters.
  • a further object of the invention is the provision of an improved seamed connection between the body yand laminated, fibrous end walls of a shipping container which permits of the use of relatively inexpensive and weak fibrous material in the central layer of a multiple layer or sandwhich type container closure, yet which is nevertheless characterized by its strength and reliability in use.
  • containers embodying the present invention may be made at lower cost by economizing in material quality, material costs,
  • An ancillary object of the invention is the provision of a novel reinforced end connection between the body and end Wallsof a fibrous shipping container and which permits use of a lighter gauge metallic reinforcing ring than 1s commonly employed with conventional reinforced container constructions, yet wherein substantially the same degree of strength and protection is afforded the seamed connection by the lightweight metallic reinforcing ring as has heretofore been afforded the seamed connection of conventional containers employing heavier gauge metallic reinforcing rings.
  • FIGURE 1 is a side elevation of a shipping container embodying the features of the present invention
  • FIG. 2 is a vertical cross-sectional view on an enlarged scale taken substantially along the line 2 2 in FIG. l, here depicting details of the improved connection between the body and end walls of the exemplary container;
  • FIG. 3 is a vertical cross-sectional view similar to FIG. 2, here illustrating the novel container end connection duringdan initial stage in the method of manufacture thereof;
  • FIG. 4 is an enlarged vertical cross-sectional view similar to a portion of FIG. 2, but here depicting a slightly modified end wall construction lalso embodying the features of the present invention.
  • FIG. 1 an exemplary shipping container, generally indicated at 10, made in accordance with ⁇ the present invention.
  • the exemplary container includes a body wall 11 and a closure or end member, generally indicated Iat 12, the wall I111 and end member 12 being seamed together as shown at 14.
  • the en-d member 12 constitutes the container bottom.
  • a similar end member could also be secured to the upper end of the body wall 11 in accordance with the invention, thus providing a container top (not shown).
  • the end member 12 is of a sandwich-type construction, consisting 4of an inner central layer or lamination 15 sandwiched between a pair of outer layers or laminations 16.
  • the individual laminations may be made of a wide variety of commercially available fibrous sheet materials such, for example, as fiber, paper, or -other natural or synthetic materials.
  • the in vention will be described in conjunction with a cylindrical container 10 having an end member 12 consisting of an inner or central layer 15 of relatively weak and inexpensive paperboard such, for example, as millboard or chipboard, the central layer being sandwiched between a pair of relatively strong fibrous outer layers 16 which, merely by way of example, may comprise sheets of kraft liner board.
  • the body wall -11 of the container may also be formed of suitable fibrous materials.
  • the body wall may be of laminar construction (not shown) and formed of a web of kraft paper or the like wound convolutely or helically about a suitable forming mandrel.
  • the body wall may, if desired, have other than the cylindrical configuration shown.
  • the end member 12 is formed of a plurality of equidimensional laminations 15, 16 as measured in a transverse direction; eng., where the container is cylindrical as here shown, the layers 15, 16 have equal or substantially equal dia-meters and, the initial diameter of all layers exceeds the internal diameter of the container Wall.
  • the body wall 11 of the container 10 has formed therein an inwardly extending circumferential rib 18 which is formed adjacent the marginal extremity of the body wall.
  • a metallic reinforcing ring -19 may be positioned in proximity to the connection Iprior to the seaming operation, for example, by placing the ring 19 in surrounding relation to the margin-al extremity of the body wall 11.
  • the reinforcing ring 19 is folded over with the body Wall and end member with the free extremity of -the ring 19 being clamped in the seamed connection.
  • the ring 19 could be secured to the container in other ways and still serve to reinforce the resultant im proved connection.
  • the ring L19 could be mounted within the fold seam 14 and its edge similarly folded over together with the peripheral edge of the end member 12 and the marginal extremity of the body wall 11.
  • the end member 12 comprises at least three layers of fibrous material.
  • the cent-ral layer 15, which provides the body of the end member, is formed of paperboard or the like, and it serves to space the relatively stronger outer layers 16 apart, thus providing additional strength. Since ⁇ the central layer 15 is sandwiched between relatively stronger outer layers 16, the latter preferably being made of kraft liner board or the like, the central layer can be made of fibrous material of relatively poorer quality such as millboard or chipboard. Although the poorer quality millboard or chipboard is normally not capable of withstanding the deformation resulting from the seaming operation, the protection afforded by the stronger outer layers 16 prevents cracking or breaking of the central layer as the latter is folded.
  • the outermost or external layer 16 (e.g., the lowermost layer 16 as viewed in FIG. 4) may be coated or impregnated with a bituminous liner 17- While such a liner is water repellant, it does not afford a moisture barrier and, consequently, in keeping with this aspect of the invention, the 'bituminous liner may be laminated to the layer 16 by means of a layer 17 of bitumen.
  • the latter is initially formed with an upstanding peripheral flange 20 (FIG. 3), for example, by bending the edge of the laminar end member out of the plane of the central disc portion thereof.
  • an upstanding peripheral flange 20 (FIG. 3)
  • provision is made for controlling lthe internal stresses developed in the end member 12 during a seaming or folding operation.
  • a-t least the outermost layers 16 of the end member 12 are put under radial tension during the seaming operation.
  • the peripheral ange 20 is preferably formed with a slight taper (as best shown in FIG. 3) so that the ange 20 flares outwardly from the end member 12.
  • the degree of taper is such that the maximum diameter of the tapered flange is substantially equal to -the internal d1- ameter of the body wall 11 while the smallest diameter of the tapered ange is considerably less than the internal diameter of the body wall 11.
  • the end member 12 is effectively placed underV a radial tension.
  • the free extremity of the body wall 11 is compressed or contracted, thereby tending to expand the latter so as to increase, or at the very least, to maintain the tension in the outer layers 16 of the end member y12 upon removal of the container from the seaming apparatus.
  • a peripherally continuous body wall 11 is formed, the wall preferably having a circumferential, inwardly extending rib 18 formed therein.
  • the w-all may be formed in a conventional manner as, for example, by convolutely or helically winding a web of sheet material about a forming mandrel.
  • a laminated end member is then formed by sandwiching a sheet of paperboard or the like between axially spaced layers of relatively stronger fibrous material such as kraft liner board.
  • the individual laminations or layers have like transverse dimensions and all are initially formed lslightly largerthan the internal dimension of the body wall 11.
  • the peripheral edge of the end member 12 is bent to form an upst-anding flange either prior to or incident to insertion of the end member into the opening in the body wall 11, rand the flange thus formed'is then folded over with the marginal extremity of the body wall 11 to form a novel seamed connection 14.
  • the rib 18 formed in the body wall 11 serves 'as a seat for the end member 12, thus insuring that when the two pieces are seamed together, an annular portion of the latter is clamped bet-Ween the rib and the seamed connection. Still greater strength is achieved by positioning a metallic reinforcing ring in proximity to the seamed connection prior to a seaming operation and simultaneously folding the ring, body wall extremity, and peripheral edge of the end member together to form a reinforced seam.
  • the end member 12 is placed under radial tension during the seaming operation, that is, the outer layers 16 are subjected to radial tensile forces during the seaming operation and, since seaming causes the body wall to tend to expand in the vicinity of the plane of the end member, such radial tension is maintained even after the container is removed from the seaming apparatus. It has been found that this serves to increase the resistance of the end member 12 to bending loads,
  • the present invention contemplates laminar end members 12 having equal diameters
  • the different layers may be glued or otherwise bonded together in laminar form while in the sheet or web state, thus permitting completely formed end members to be blanked directly from the sheet or web thus formed. This, of course, insures substantial savings in both time and expense over the prior art constructions wherein the various layers had different diameters, thus requiring that each lamination be prebl-anked prior to its assembly with adjacent laminations.
  • the outer layers 16 of the container bottom may possess other characteristics in addition to being stronger than the central layer 15.
  • one or both of the layers 16 may be formed of a liquid impervious material.
  • the outermost layer 16 i.e., the bottom layer as viewed in FIG. 2 may have liquid repellant properties while the internal layer 16 (i.e., the top layer as viewed in FIG. 2) may be liquid impervious.
  • containers embodying the features of the present invention are characterized by their strength and durability, particularly in the region of the seamed connection 14. Moreover, in those instances where the container requires additional protection in the form of a reinforcing ring 19, the latter can be formed of ⁇ a lighter gauge metal than is conventionally used while still attaining the same degree of additional reinforcement.
  • a shipping container comprising, in combination, a body wall, an end Wall, said end Wall being formed of at least three laminations of sheet material with said laminations being substantially equidimensional transversely thereof and having an initial diameter greater than the internal diameter of the body Wall, the outermost ones of said laminations being formed of relatively strong fibrous material sandwiching the central lamination, said central lamination being formed of fibrous material relatively weaker than the fibrous material defining said outermost laminations, the peripheral edges of all of said laminations being bent out of the plane of said end wall to define a laminated peripheral flange surrounding a central disc portion of said end wall, and said ange and the marginal extremity of said body wall being folded together inwardly beneath said c'entral disc portion to define a fold seam connection therebetween rigidly securing said end wall to said body wall.
  • a shipping container as set forth in claim 1 further characterized in that said outermost laminations are formed of kraft liner board and said central lamination is formed of paperboard.
  • a shipping container as set forth in claim 2 further characterized in that said central lamination is formed of millboard.
