Definitions

  • This invention relates generally to paperboard containers and, more particularly to a laminated wall construction for same, including oxygen resistant barriers or layers.
  • barrier layer It is also well known to coat the barrier layer with a heat-sealable material, such as low density polyethylene. Such a coating tends to scavenge flavor essences and aromas from various fruit juices.
  • a general object of the invention is to provide an improved, economical paperboard container which is capable of improving the shelf life of fruit juices.
  • Another object of the invention is to provide a container having an improved wall construction of suitable barriers or layers which avoid the above described negative characteristics, and which are compatible with one another insofar as bonding and sealing are concerned.
  • a further object of the invention is to provide a paperboard container for retaining flavors and aromas, while efficiently preventing the penetration of oxygen, wherein the wall construction includes a suitable combination of layers of polyester and polyvinylidene chloride.
  • Still another object of the invention is to provide such a container wherein the polyester is an amorphous polyethylene terapthalate.
  • Figure 1 illustrates the inside surface of a container blank 10.
  • the container blank 10 is separated into three general groups by staggered score lines 12 and 14.
  • the group above the staggered score line 12 is referred to as the top closure group 16.
  • the group between staggered score lines 12 and 14 is referred to as the body group 18.
  • the group below the staggered score line 14 is referred to as the bottom closure group 20.
  • the container blank 10 is defined on its sides by side edges 22 and 24 and is separated vertically by a series of score lines 26, 28, 30 and 32.
  • the score lines 26, 28, 30 and 32 divide the body group 18 into side wall panels 34, 36, 38 and 40, with the edge 22 and the score line 26 defining a side seam flap 42.
  • the top closure group 16 is mounted on the upper end of body group 18.
  • Triangular end panels 44 and 46 are mounted to upper ends of the side wall panels 34 and 38, respectively.
  • the triangular end panel 44 has a pair of adjacent fold-back panels 48 and 50 mounted on its upper sides and the triangular end panel 46 has a pair of fold-back end panels 52 and 54 mounted on its upper sides.
  • a pair of inner rib panels 56 and 58 are mounted adjacent the fold-back panels 48 and 50, respectively.
  • a pair of inner rib panels 60 and 62 are mounted adjacent the fold-back panels 52 and 54, respectively.
  • a pair of roof panels 64 and 66 are mounted to the body group 18 at the upper end of the side wall panels 36 and 40, respectively.
  • a top edge member 72 defines the upper free end of top closure group 16.
  • a complete description of the top closure group 16 is not necessary to understand the principles of the present invention. However, reference is made to U.S. Patent 3,270,940 which issued September 6, 1966 for a complete description of a top closure group similar to top closure group 16.
  • the bottom closure group 20 is mounted on the lower end of body group 18.
  • a flap 74 and a fold-over flap 76 are mounted at the lower ends of the side wall panels 36 and 40, respectively, along the staggered score line 14.
  • a first minor flap 78 and second minor flap 80 are mounted at the bottom of the side wall panels 34 and 38, respectively, along the staggered score line 14.
  • a pair of fold-back panels 82 and 84 connect the first minor flap 78 to the side seam flap 42 and the flap 74, respectively.
  • the second minor flap 80 is connected to the flap 74 and the fold-over flap 76 by fold-back panels 86 and 88, respectively.
  • a bottom edge 90 defines the free end of the bottom closure group 20.
  • a fold-under flap 92 is connected by a score line 94 on the edge 90 at the center of the flap 74 for a purpose to be described.
  • the container blank 10 When the container blank 10 is being prepared for assembly as a container it will be side seamed by having the triangular end panel 44 and its associated panel segments, the side wall panel 34 and the first minor flap 78 and its associated fold-back panels 82 and 84, along with the side seam flap 42, folded about the score line 28, moving their inside surfaces into contact with the inside surfaces of the roof panel 64, the side wall panel 36 and the flap 74, with the side seam flap 42's inside surface extending past the score line 30.
  • the roof panel 66, the side wall panel 40 and the fold-over flap 76 will be rotated about the score line 32 so their inside surfaces will move toward the inside surface of the triangular end panel 46, the side wall panel 38 and the second minor flap 80 and the associated fold-back panels 86 and 88.
  • the side edge 24 will then be substantially aligned with the score line 30 and its associated edge portion will be aligned with and in contact with the outside surface of the side seam flap 42.
  • the outside surface of side seam flap 42 is secured to the inside surface of the various panel and flap members being positioned along the side edge 24. This can be accomplished in many ways.
  • One of the preferred methods is heat sealing which will establish a surface bond between the above stated members.
  • the container blank 10 can then be opened into tubular form.
  • the bottom closure group 20 will be closed and sealed, the contents will be passed into the tubular container and then the top closure group 16 will be closed and sealed, as illustrated in Figure 3.
  • the forming of the side seam blank and the closing of the top closure group is covered in detail in the above mentioned U.S. Patent 3,270,940.
  • the forming of the bottom closure group 20 is covered in detail in U.S. Patent Nos. 3,120,335 and 4,341,340.
  • the fold-under flap 92, folded along the score line 94 serves to eliminate a raw edge at the center of the four folded and sealed bottom closure panels, substantially as shown and described in U.S. Patent No. 3,294,310.
  • Layers 98 and 100 each consist of a suitable polyester, such as an amorphous polyethylene terapthalate, on respective surfaces of a central layer 102, which is the bulk or main body layer, and which may consist of a kraft paperboard, foam plastic, a synthetic paperboard, or a composite paperboard.
  • the amorphous polyethylene terapthalate has been selected for its superior heat sealing characteristics.
  • the extreme inside layer 104 is a polyvinylidene chloride.
  • the latter is applied to the layer 100 by conventional printing techniques. Accordingly, it is possible to apply the polyvinylidene chloride coating in a precise pattern, avoiding those areas of the blank which are involved in the heat sealing operation.
  • the preferred pattern is shown by the cross hatched lines on Figure 1. The end result is a superior and economical container where the durability and heat seal characteristics of the amorphous polyethylene terapthalate, and the flavor retention and barrier properties of polyvinylidene chloride are both fully utilized without having to use supplementary adhesives for laminating or additional coatings for heat sealing.
  • the thickness range for the layer 102 applies to the range of standard container sizes, i.e., half pint, pint, quart, half gallon, and gallon.
  • the preferred thickness is .022 ⁇ , with a recommended range of .020" - .024".
  • the inner cut edge 22 may be "skived" by some one of several known methods, such as that shown and described in U.S. Patent No. 4,254,693, resulting in a carton edge structure, as shown in U.S. Patent No. 4,239,150, or folded-over, as shown in U.S. Patent No. 3,294,310.
  • One of these techniques, coupled with the folded-under flap 92, serve to eliminate raw cut edges from being exposed to the liquid contents.
  • the invention provides an improved paperboard package for carrying fruit juices.
