  • ABSTRACT OF THE DSCLGSURE A paperboard container constructed from an integral blank of foldable sheet material divided by score lines into five contiguous panels, four body panels including two pairs of opposing body panels, and a side seam panel; a group of top closure panels; and a group of bottom closure panels; the bottom closure panels including two opposing major flaps respectively contiguous with each of one pair of opposing body panels and having a length greater than half the width of the other pair of opposing body panels so that the bottom edges of the two maior flaps overlap one another with the bottom closure panels in their assembled position; two opposing minor bottom flaps respectively contiguous with each of the other pair of opposing body panels, each minor bottom flap having a length selected to be from about 20 percent to about 75 percent of the length of the major bottom flaps; and a side seam bottom flap contiguous with the side seam panel and adjacent to one of the other bottom flaps, the side seam bottom flap having 4a rectangular shape and a length selected so that the bottom edge of said side seam bottom flap extends beyond the l
  • This invention relates to containers and in particular to the bottom closure structure of paperboard containers.
  • Paperboard containers are widely used for packaging a variety of products, including foods and beverages, one well known paperboard container being the so-called gable top container of the type shown in C. R. Alden Patent No. 2,750,095, issued June 12, 1956.
  • Such containers are typically erected or assembled from blanks of a predetermined geometrical configuration which have been cut from a roll of paper sheet stock having a coating of a protective thermoplastic material such as wax or polyethylene. Also, score lines are impressed on the blanks to define the top closure, bottom closure, and side wall elements or" the assembled container.
  • a paperboard container of this type is assembled on automatic machinery by folding and sealing a blank into a tubular body open at both ends, sealing together the bottom closure panels of the blank, filling the container with the desired product, and finally sealing together the gable top closure panels of the blank.
  • bottom closure of the container Since the bottom of a paperboard container is especially susceptible to damage, it is particularly important to construct the bottom closure of the container to have sufficient strength and leak resistance to maintain the integrity of the container even under severe conditions of use.
  • a bottom closure with sufficient strength is obtained by'providing a number of bottom panel elements or flaps which are folded, tucked and sealed together to form a bottom comprising several overlapping plies of paperboard.
  • This type of bottom closure structure is exemplified by the containers disclosed in A. J. Seiple Patent No. 3,120,333 and H. B. Egleston et al. Patent No. 3,120,335, both of which issued on Feb. 4, 1964.
  • the bottom closure elements include four bottom panels or flaps of approxiice mately rectangular configuration, two opposing major flaps and two opposing minor flaps.
  • the lengths of the 4major and minor flaps differ primarily in that one of the major flaps is provided with a tuck-in extension and the other major flap is provided with a fold-over extension, whereas the minor flaps have no such extensions.
  • the minor flaps are divided by score lines into a center triangular portion and two triangular gusset portions, one on either side of the center triangular portion.
  • the bottom closure is formed by folding the opposing major and minor flaps toward each other and the center of the container.
  • each of the gussets on each minor ap causes each of the gussets on each minor ap to be folded under a corresponding one of each of the opposing major flaps, so that gussets on opposing minor flaps which yare folded under the same major flap cooperate to form a slot under each major flap.
  • One of these slots forms a tuck-in slot under the major flap having the fold-over extension to receive the tuck-in extension of the opposing major flap when the two major aps are brought sufficiently close together.
  • the major flap having the fold-over extension is being placed on top of the major ap having the tuck-in extension so that the foldover extension overlaps the tuck-in extension.
  • the edges of the gussets folded under opposing major flaps are brought into close abutment but wit-hout crus-hing the edges against one another and thereby impairing the integrity of the container.
  • the present invention there is provided a strong, leak resistant bottom closure which may be assembled on existing -automatic equipment which does not require the observance of the kind of close tolerances necessary in t-he assembly of conventional bottom closures.
  • the bottom closure structure of the present invention permits a significant saving in paperboard to be realized, since container blanks provided with the bottom closure elements of this invention may be cut from a narrower roll of paperboard than that required for container blanks having a conventional bottom closure structure of the variety described above.
  • the bottom closure of the present invention also comprises two opposing major flaps and two opposing minor flaps, both of rectangular configuration, with each of the two major flaps being provided with a fold-over extension, and with each of the minor flaps being made substantially shorter than the major flaps.
  • each of the minor flaps should be on the order of 20 to 75 percent of the length of each of the major flaps, with the upper limit of this percentage range depending upon the size of the container, but in every case the maximum length of the minor fiap is that which permits an overlapping rather than a ing relationship between the two major flaps.
  • Each of the minor flaps in the bottom closure of this invention is divided by score lines into a central trapezoid shaped portion and two triangular gusset portions, one on either side of the central trapezoid portion.
  • the two minor flaps and the two major flaps are folded toward the center of the container, and although the gussets are folded under the major flaps, the gussets are sufficiently short so that they extend but a relatively short distance toward the center of the container, hence no tucking is required to assemble the container of this invention, the fold-over extensions of the two major tlaps being brought together by simply folding one over the other.
  • Another advantage resulting from the relatively short length of the minor naps of the present invention is that container blanks with the short minor flaps of this invention can be cut from a narrower web of paperboard, thereby saving a significant amount of paperboard.
  • This advantage was discovered by observing that the short minor flaps permitted the two streams of container blanks cut from each web to nestle together more closely than conventional container blanks so that the same number of container blanks can be cut from a narrower web.
  • the elimination of tucking also eliminates the need for tapered major flap corners; consequently, no dies for cutting tapered major ap corners are required in converting a paperboard web into container blanks having the bottom closure configuration of this embodiment.

  • FIG. 1A a ilat blank 10 from which a container having a conventional bottom closure is assembled.
  • Blank lo is divided by vertical score lines 21, 22, 23, 24 into four body panels 11, 12, 13, 14 and a side seam panel 15.
  • Each panel 11 through 15 is divided by horizontal score lines 25 and 26, which are approximately perpendicular to vertical score lines 21, 22, 23, 24, into three sections, a top section, a side wall section and a bottom section.
  • top sections which are denoted 11a, 12a, 13a, 14a, 15a
  • side wall sections which are denoted 11b, 12b, 13b, Mb, 15b
  • Bottom sections le, 12e, 13C, 14e, 15C of blank 1G collectively constitute the elements from which the bottom closure of a conventional container is assembled.
  • Sections 11e and 13e are the major bottom flaps
  • sections 12e and 14e are the minor bottom flaps
  • section 15e is the side seam bottom ap. It is observed that both the minor and major flaps are substantially rectangular in shape, with the minor tiaps being somewhat shorter than the major flaps primarily because of the extensions 11d and 13d on the major flaps.
  • one of these rnajor flap extensions, 11d forms a tuck-in extension in the completely assembled container, while the other major flap extension, 13d, forms a oldover extension in the completely assembled container.
  • both corners of tuck-in extension 11d are tapered, thereby to facilitate the assembly of the bottom closure in which extension 11d is tucked into a slot under major ap 3c in the manner shown in FIG. 4A.
  • one of the corners of extension 13d is tapered to prevent the build up of excessive plies of paperboard which would otherwise occur if extension i3d overlapped side seam bottom tiap 15C.
  • Side seam flap 15e ⁇ is also tapered to complement the corner taper on extension 13d, and as shown in FIG. 5A, it is apparent that these two tapered corners on major ap extension 13d and side seam bottom ap 15e must be carefully dimensioned in order to prevent unwanted overlapping in the finally assembled container.
  • the minor flaps 12a ⁇ and 14C of container 10 are respectively divided by pairs of diagonal score lines 33, 34 and 31, 32 into triangular central portions 51 and 41 interposed between triangular gusset portions 52, 53 and 42, 43.
  • FIG. 4A The spatial relationship of these central and gusset portions is illustrated in FIG. 4A in which blank 10 is shown in partially assembled form. Before the bottom closure is assembled, the blank 10 is formed into a tubular body by folding panels 11, 12, 13, 14 about vertical score lines 21, 22, 23, 24 and sealing together side seam panel l5 and vertical panel 11. The bottom closure of the tubular shaped container is then assembled by folding the major and minor flaps about score line 26 so that the central portions of the flaps are moved toward the center of the container and opposing flaps are moved toward each other.
  • FIG. 4A illustrates how gusset 43 is folded about score line 32 to form part of a slot under major flap 13e which receives the tuck-in extension 11d of major flap 11C.
  • FIG. 5A A completely assembled bottom closure is shown in FIG. 5A, in which it is noted that the edges 45, 44 of gussets 43, 42 and the edges 54, 55 of gussets 52, 53 are folded under opposing major aps to be brought into close abutment when the bottom closure is finally assembled.
  • edge 45 of gusset 43 and edge 44 of gusset 42 are brought into close abutment
  • edge 54 of gusset 52 and edge 55 of gusset 53 are brought into close abutment. Because of the close proximity of the opposing gusset edges, it is necessary to cut and score the container blanks with precision and to maintain careful adjustment of the automatic assembling equipment so that opposing gusset edges do not crush one another during the assembly of the bottom closure.
  • FIG. 1B this drawing illustrates a container blank 11G embodying the bottom closure structure of the present invention.
  • Blank 110 is divided by vertical score lines 121, 122, 123, 124 into four body panels 111, 112, 113, 114, and a side seam panel 115.
  • Each panel 111 through 115 is divided by horizontal score lines 125 and 126, which are approximately perpendicular to vertical score lines 121, 122, 123, 124, into three sections, a top section, a side wall section, and a bottom section.
  • the top sections, designated 111e, 11211, 113a, 1140, 115a constitute the elements of a gable top closure which may be of any well known variety such as that shown in FIG. 1A, while the side wall sections, designated 111b, 11217, 113b, 114k, 115b, constitute the vertical side walls in the completely assembled container.
  • Bottom sections 111C, 112C, 113C, 114e, 115e of blank 11) collectively constitute the structural elements of the bottom closure of this invention.
  • Sections 111C and 113C are the major bottom flaps

  • the two minor bottom flaps 112e and 114e are respectively divided by pairs of diagonal score lines 133, 134 and 131, 132 into trapezoid shaped central portions 151 and 141 interposed between triangular gusset portions 152, 153 and 142, 143. The spatial relationship of these central and gusset portions is illustrated in FIG. 4B.
  • minor flaps 112e and 114C are constructed to be substantially shorter than major aps 111C and 113C, measuring from score line 126 to the bottom edges of the minor flaps and from score line 126 to the bottom edges of extensions 111:1.' and 113d of the major flaps, thereby to obtain several unexpected advantages in the manufacture and assembly of containers embodying this structure.
  • the amount by which minor flap length is to be made substantially shorter than major ap length is not critical, since minor ap length, expressed as a percentage of major iiap length, may be selected from within the range of 20 to 75 percent.
  • both the minor aps and the major flaps have a rectangular shape in which the width of each rectangle is equal the assembled container.
  • the major bottom is contiguous.
  • the length of the major bottom iiaps is selected to be greater than one half of their width so that in the assembled position of the bottom closure, the edges of the two major aps overlap one another by an amount sufficient to provide a relatively strong bottom for the assembled container.
  • the major bottom flaps of this invention may have about the same length as the maior bottom flaps of conventional bottom closure structures.
  • the lower limit of 2() percent for the length -of minor bottom flaps relative to the length of major bottom aps in this invention is applicable to containers of gallon, half gallon, quart and smaller capacities, but the upper percentage limit depends upon the size of the cross-section of the container.
  • the upper percentage limit on the length of minor bottom flaps relative to the length of major bottom flaps is on the order of 75% for gallon containers, 69% for half gallon containers, and 62% for quart containers as Well as smaller capacity containers having the same cross-section as quart containers.

  • the bottom closure is assembled by folding the major and minor flaps about score line 126 so that the central portions of the aps are moved toward the center of the container i' and opposing flaps are moved toward each other. Also,
  • FIG. 4B illustrates how gusset 143 is folded about score line 132 to be positioned under major tlap 113C, and it is observed that by constructing the minor flaps 112C, 114e to be sufficiently short in length relative to the major aps 111C, 113e, the slot formed between gusset 143 in its foldedunder position and major iiap 113C extends but a short distance toward the center of the container.
  • assembling the bottom closure of this invention does not require the -overlapping portions o1- extensions 111d or 1130,' of the major aps to be tucked into a slot of any kind, but requires only that one major flap be folded over the other, as shown in FIGS. 4B, 5B, 6B.
