Definitions
- This invention relates generally to thermo lastic-coated paperboard containers and, more particularly to containers with internal raw edge protection, and the process for constructing same.
- a general object of the invention is to provide an improved, economical paperboard container which is capable of improving the shelf life of liquids.
- Another object of the invention is to provide a container having an improved wall construction including means for preventing internal edge wicking.
- a further object of the invention is to provide a paperboard container wherein the outside edge portion of the side seam flap is "skived” or shaved to a feather edge, has a suitable sealant applied thereto, and is then pressed into contact with the inside surface of the adjacent overlapped panels, thereby eliminating raw edges from the inside surfaces of the container.
- Figure 1 is a layout view of the outside surface of a container blank body, to which the present invention could be adapted?
- Figure 2 is a fragmentary view of a portion of the Figure 1 structure after an operational step has been performed thereon;
- Figure 5 is a flat side seamed blank made from the container blank shown in Figure 1, and showing the outside surface thereof;
- Figure 7 is a perspective view of a container fabricated from the blanks shown in Figures 1 and 2;
- Figures 3, 4, 6 and 8 are enlarged fragmentary cross-sectional views taken along lines 3-3, . 4-4, 6-6 and 8-8, respectively of Figures 1, 2, 5 and 6, and looking in the directions of the respective arrows; and
- Figure 4A is an alternate embodiment with respect to Figure 4 which, like Figure 4, results in the closure relationship with an adjacent panel, as shown in Figure 6. Best Mode of Carrying Out the Invention
- Figure 1 illustrates the outside 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 staggered score line 12 is referred to as top closure group 16.
- the group between staggered score lines 12 and 14 are referred to as body group 18.
- the group below staggered score line 14 is referred to as 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 group body 18 into side wall panels 34, 36, 38 and 40 and 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 connected to upper ends of the side wall panels 36 and 40, respectively, by the score line 12.
- the triangular end panel 44 has a pair of adjacent fold-back panels 48 and 50 mounted on its upper sides and separated therefrom by diagonal score lines 49 and 51
- the triangular end panel 46 has a pair of fold-back end panels 52 and 54 mounted on its upper sides, separated therefrom by diagonal score lines 53 and 55.
- a pair of inner rib panels 56 and 58 are connected to the fold-back panels 48 and 50, respectively, by ' a score line 60.
- a pair of inner rib panels 62 and 64 are connected to the fold-back panels 52 and 54, respectively, by the score line 60.
- a pair of roof panels 66 ' and 67 are connected to the body group 18 at the upper end of the side wall panels 34 and 38, respectively, by the score line 12.
- a pair of inner rib panels 68 and 69 are connected to the roof panels 66 and 67, respectively, by the score line 60.
- a pair of outer sealing rib panels 70 and 72 are connected to the upper end of the inner rib panels 68 and 69, respectively, by spaced score lines 73.
- the bottom closure group 20 is mounted on the lower end of the body group 18.
- a tuck-in panel 74 and a overlap panel 76 are connected to the lower ends of the side wall panels 34 and 38, respectively, along the staggered score line 14.
- a first triangular panel 78 and second triangular panel 80 are connected to the bottom of the side wall panels 36 and 40, respectively, along the staggered score line 14.
- a first pair of fold-back panels 82 and 84 are connected to the first triangular panel 78 adjacent the tuck-in panel 74 and the overlap panel 76, respectively, by diagonal score lines 83 and 85.
- a second pair of fold-back panels 86 and 88 are connected to the second triangular panel 80 by diagonal score lines 87 and 89 adjacent the overlap panel 76 and the lower end of the side seam flap 42.
- a strip 90 which is substantially triangular in cross-section, has been removed or "skived” in any suitable manner from the outside edge portion of the side seam flap 42, leaving a tapered raw paperboard surface 92.
- the raw paperboard surface 92 is then covered with a suitable sealant, represented as 94, by any convenient method.
- Figure 1 illustrates the side seam flap 42 after the skiving operation has been performed thereon.
- Figure 2 represents the skived side seam flap 42 after having the sealant 94 applied thereto.
- the sealant 94 may be applied to a predetermined width along the full length of the side wall panel 34, as shown in Figure 4A, and the associated aligned portions of the top panel segments 66, 68 and 70, and the bottom panel 74. If desired, both the tapered surface 92 and the width of panels 34, 66 , 68 and 70 may have the sealant 94 applied thereto.
- the container blank 10 When the container blank 10 is being prepared for assembly as a container it is side seamed ( Figure 5) by having the top triangular end panel 46 and related panel segments, the side wall panel 40 and the bottom triangular panel 80 and related panel segments all rotated about the score line 30 such that their inside surfaces contact the inside surfaces of the roof panel 67 and related panel segments, the side wall panel 38 and the overlap panel 76, with the side seam flap 42 extending past the score line 28, adjacent the edge portions of the side wall panel 36, the top panels 44, 50 and 58, and the bottom panels 78 and 84.
- the roof panel 66, the segments 68 and 70, the side wall panel 34 and the tuck-in panel 74 are folded about the score line 26, bringing their inside surfaces into contact with the inside surfaces of the triangular end panel 44 and related panei ⁇ segments, the side wall panel 36 and the triangular panel 78 and related panel segments, and the outside surface of the side seam flap 42.
- the side edge 22 is substantially aligned with the score line 28, and the associated edge portions of the panels 34, 66, 68, 70 and 74 are in contact with the outside surface of the side seam flap 42.
- the entire outside surface of side seam flap 42 is then secured to the inside surface of the latter panel edge portions. This can be accomplished in many ways.
- One of the preferred methods is heat sealing which will establish a surface bond between the respective members.
- the container blank 10 can then be opened into tubular form, preparatory to having the bottom closure group 20 formed and sealed, as described in detail in U.S. Patent No. 3,120,335.
- the invention provides an improved liquid-carrying container wherein raw edges are eliminated from the inside wall thereof to thus prevent edge wicking and, hence, readying the container for a longer shelf life than if inner raw paperboard edges were exposed. While but one embodiment of the invention has been shown and described, other modifications thereof are possible.
