Definitions

  • This invention relates generally to thermoplastic coated paperboard containers and blanks for constructing same and, more particularly, to a folded end closure therefor.
  • Containers for beverages such as milk and juices are conventionally constructed from thermoplastic coated paperboard-
  • One type of these containers includes a top end closure with a folded gable roof having a vertically projecting seal at the roof ridge for sealing the container.
  • U..S. Patent No. 3,270,940 The bottom end closure for same is conventionally- of the infolded type, such as. that shown by U.S. Patent No. 3,120,335.
  • Another type of container includes a slant top or a flat top end closure wherein what could otherwise be a vertically projecting seal, or a slanted seal, may be folded flat and releasably secured to the rest of the closure.
  • U.S. Patents 3,869,078 and 4,211,357 disclose such slant and/or flat top closures.
  • U.S. Patent Nos. 4,012,997 and 4,093,115 disclose a container folding method and the container made by the smethod, wherein one side of the gable panels of the top end closure is provided. with double score lines extending parallel to each other. Folding of a top seal of the end closure from a vertical position to a flat position requires the application of a downward force along the lower double score line on one side of the top seal and the application of another force to bend the top seal downwardly.
  • a general object of the invention is to provide an improved flat end closure for a liquid carrying container which may be used for either a top or a bottom end closure.
  • Another object of the invention is to provide an improved flat end closure which includes means for causing such flat end closure to have an outer surface which is effectively square with the side walls of the container body.
  • a further object of the invention is to provide a flat end closure which includes score lines between the body side wall panels and the bottom closure panels wherein the score lines of one oppositely disposed set of score lines are at a different elevation from each other, and the score lines of the other oppositely disposed set of score lines each include a horizontal half segment which is positioned above the higher of the first set of score lines, and a slanted half segment extending downwardly from the horizontal half segment to a point just above the lower of the first set of score lines, the arrangement being such that the outer surface of the end closure is effectively square with the side wall panels.
  • Still another object of the invention is to provide such a flat end closure wherein the outermost panel of the bottom closure arrangement extends all the way across the container providing both a firm, square base for the container and a smooth surface for printing thereon.
  • FIG. 1 illustrates a container blank 10 formed in accordance with the principles of the present invention.
  • the container blank 10 is generally divided into three sections including a first end closure (not shown) , a body portion 12, and a second end closure 14.
  • a staggered, generally horizontal score line 16 extends transversely across the container blank 10 and separates the end closure 14 and the body portion 12.
  • the body portion 12 comprises a plurality of integrally connected body panels 18, 20, 22 and 24, and a side seam flap 26.
  • the container blank 10 is defined on its longitudinal sides by its edges 28 and 30.
  • the body panels 18, 20 22 and 24, and the side seam flap 26, are defined by vertical score lines 32, 34, 36 and 38.
  • the end closure 14 comprises panel sections 40, 42, 44, 46 and 48 connected to the body panels 18, 20, 22, 24 and '26, respectively, by the staggered score line 16.
  • the staggered score line 16 includes aligned horizontal score line segments 50 and 52 between adjacent body and end closure panels 18 and 40, and 26 and 48, respectively. Between the adjacent body and end closure panels 22 and 44, the score line 16 includes a segment 54 is horizontal, but . higher than the horizontal segments 50 and 52. Between the adjacent body and end closure panels 20 and 42, the score line 16 includes a segment which comprises a sloped half 56 and a horizontal half 58, interconnected at the vertical canter of the panels. The end of the sloped half segment 56 intersects the vertical score line 32 at least the equivalent of the paperboard thickness above the adjacent end of the segment 50, while the end of the horizontal half segment 58 intersects the vertical score line 34 at least the equivalent of the paperboard thickness above the adjacent end of the higher horizontal segment 54.
  • a sloped half segment 60 and a horizontal half segment 62 between the remaining adjacent body and end closure panels 24 and 46 are the mirror images of the- half segments 56 and 58 and cooperate with the horizontal segments 52 and 54, respectively, in the same manner as the half segments 56 and 58 cooperate with the respective horizontal segments 50 and 54.
  • the panel 40 is preferably plain or unbroken, while the panel 44 is divided basically into two portions 63 and 64 by a horizontal score line 65.
  • the panel section 42 includes a pair of fold-back panel portions 66 and 68 connected on opposite sides of a gusset panel 70 by diagonal score lines 72 and 74, respectively, the latter extending from the score line segments 56 and 58, respectively, a predetermined distance from the vertical score lines 32 and 34, respectively, and defining angles 76 and 78 with the respective score line segments 56 and 58.
  • the predetermined distance compensates for the thickness of the paperboard and helps to eliminate bulging when the closure is formed-
  • the fold-back panel portions 66 and 68 are also connected to the closure panels 40 and 44, respectively, via the respective score lines 32 and 34.
  • the fold-back panel portions 66 and 68 are separated from each other beyond the gusset panel 60 by a vertical score line 84.
  • the fold-back panel 68 is divided into an inner segment 68a and an outer segment 68b by a horizontal score line 82 which is substantially aligned with the score line 65 and intersects the juncture between the interconnected ends of the vertical score line 84 and the- diagonal score line 74.
  • the diagonal score line 72 intersects the vertical score line 84 a predetermined distance below the end of the score- line 82, forming a short vertiical score line segment 86 for the gusset panel 70.
  • the outer free cut edge of the panel section 42 is formed as a sloped edge 88, extending between the adjacent corners of the panel sections 40 and 44, the latter sections being substantially the same size, but staggered in height as indicated above relative to the positions of the horizontal score lines 50 and 54..
  • the panel section 46 is a mirror image of the panel section 42, and includes a pair of fold-back panel portions 90 and 92 connected on opposite sides of a gusset panel 94 by diagonal score lines 96 and 98, respectively, the latter extending from the score line segments 60 and 62, respectively, a predetermined distance from the vertical score lines 38 and 36, respectively, compensating for the thickness of the paperboard, as indicated above relative to the diagonal score line segments 72 and 74.
  • the angles between the. lines 60 and 96,. and between the lines 62 and 98 are equal to the angles 76 and 78, respectively.
  • the fold-back panel portions 90 and 92 are separated from each other beyond the gusset panel 70 by a vertical score line 100.
  • the fold-back panel 92 is divided into an inner segment 92a and an outer segment 92b by a horizontal score line 106 which is substantially aligned with the score line 55 and intersects the juncture between the interconnected ends of the vertical score line 100 and the diagonal score line 106.
  • the diagonal score line 96 intersects the vertical score line 100 a predetermined distance below the end of the score line 106, forming a short vertical score line segment 110 for the gusset panel 94-
  • the outer free cut edge of the panel section 46 is formed as a sloped edge 112, extending between the adjacent corners of the panel sections 44 and 48, the latter sections being substantially the same height, but staggered in height as indicated above relative to the positions of the horizontal score lines 52 and 54.
  • the container blank 10 illustrated in Figure 1 is first formed into a side seamed blank by rotating the body panel 24 and the side seam flap 26 as a unit about the vertical score line 36, and having the inside surfaces of the body panel 24 come into contact with the inside surface of the body panel 22, with the vertical-score line 38 positioned next to the vertical score line 34, and with the inside surface of the side seam flap 26 contacting the inside surface of the body panel 20 adjacent the vertical score line 34-
  • the body panel 18 is then rotated about the vertical score line 32 to bring its inside surface into contact with the. inside surface of the body panel 20.
  • the inside surface of the body panel 18 along the edge 28 comes into contact with the outside surface of the side seam flap 26, and the edge 28 is positioned parallel and substantially aligned with the vertical score line 38.
  • the various members of the end closure 14 will make similar movements.
  • the container blank 10 is then adhesively seamed in the location where the inside area of the body panel 18 comes into contact with the outside surface of the side seam flap 26.
  • the side seamed blank is opened up into a squared condition, as shown in Figure 2, after which the end closure 14 is formed.
  • the panel section 42 is folded at the score line halves 56 and 58 over the end of the squared bcdy and towards its center.
  • the panel section 46 is rotated toward the middle of the squared body about the horizontal score line halves 60 and 62.
  • the outside surfaces of the infolded panel portions 66 and 68b will. be rotated towards each other about the vertical score line 84, and the infolded panel portions 90 and 92b will. likewise have their outside surfaces rotated towards each other about the vertical score line 100.
  • the inside surfaces of the infolded panel portions 68b and 92b will come into contact with the panel portion 64, and the inside surfaces of the panel portions 66 and 90 will come into contact with the panel section 40.
  • the resultant four-layer thick fin .( Figure 3) is then either flattened so as to cause the panel portion 63 to contact the panel portion 64 and be sealed together, or first sealed together while in a slanted attitude of Figure 3 and then bent into a flat attitude with the panel portion 6-3 contacting the panel portion 64 and being sealed thereto to form the closed end arrangement shown in Figure 4.
  • the sealing of the four-layer thick fin of the closure in the slanted attitude is preferably accomplished by a sonic or high frequency vibration sealing means, similar to that disclosed in U.S. Patent No. 3,910,014, or may also be accomplished by other means,- such as heated air and pressure, if desired. If flattened first, prior to being sealed, such closing and sealing operations may be accomplished on a mandrel in any well known manner, such as by using the forming and sealing machine disclosed in U.S. Patent No. 3,303,761.
  • the outside full, unbroken panel 40 is also adaptable to being printed thereon for "billboard"' or advertising purposes when the filled and sealed container is lying on its side while being displayed for sale, or standing upright in the case of a top closure.
  • the panel section 42' in this embodiment is similar to the panel section 42 of Figure 1, except that a substantially horizontal score line segment 80 divides.the fold-back panel 66 into an inner segment 66a and an outer segment 66b.
  • the score line segment 80 intersects the vertical score line 84 at the juncture therewith of the diagonal score line 72.
  • the panel section 46' is a mirror image of the panel section 42', and is similar to the panel section 46 of Figure 1, except that a substantially horizontal score line segment 104 divides the fold-back panel 90 into an inner segment 90a and an outer segment 90b.
  • the score line segment 104 intersects the vertical score line 108 at the juncture therewith of the diagonal score line 96.
  • a score line segment 114 divides the panel section 48 into two portions 116 and 118, and extends as a continuation of the score line segment 104.
  • Such flattening process may be further enhanced by the addition of a horizontal score line 120, as illustrated in Figure 6, across the panel 40', dividing the latter into panel portions 122 and 124.
  • the score line 120 is substantially aligned with the score line segment 80.
  • the closing process includes a step wherein the end closure assumes a position as shown in Figure 7, as opposed to the slant attitude of Figure 3, i.e., the panel 40' is bent to some degree along the score line 120, providing the slant configuration of the adjacent outside panel portions 64 and 124 while the panel portions 63 and 122 approach a substantially flat attitude.
  • the fin provided by the panel portions 64 and 124 may then be sealed and flattened or, alternatively, flattened and then sealed.
  • the invention describes a flat end closure for either the top or the bottom of a paperboard container, wherein the flat end closure includes score line and panel means for assuring that the end closure is square with, or mormal to, the sides of the container for standing or stacking purposes.
  • the invention describes a flat end closure for a paperboard container, wherein the flat end closure exposes a full, unbroken panel, suitable for not only providing a steady, square-standing container, but, additionally, providing a full cress-sectional area billboard for advertising purposes.
