Definitions

  • This invention relates generally to a carton having a reinforced integrated handle opening in an end wall, and particularly, to a carton formed from a single blank.
  • Carton manufacturers often face the challenge of providing a carton having ergonomic handle openings that are sufficiently strong to withstand the stress generated by the weight of articles enclosed. This is particularly so when the handle is integral to the end wall of the carton and when the burst strength of the material comprising the end wall is insufficient to avoid failure of the handle and the end wall itself.
  • One approach to resolving this quandary is to construct the carton from a stronger material such as corrugated board or from a sheet of material of a relatively higher caliper.
  • a handle aperture in a carton end wall may be reinforced by outlining its edges with an additional layer of sheet material.
  • the various embodiments of the present invention overcome the shortcomings of the prior art by providing a sleeve type carton formed from a single sheet of paperboard or other foldable sheet material, the carton having a handle opening disposed in an end wall, wherein at least the weight bearing portion of the periphery of the handle opening is reinforced by three layers of sheet material.
  • the various embodiments of the exemplary carton include a top panel, a first side panel hingedly connected to the top panel, a bottom panel hingedly connected to the first side panel, a second side panel hingedly connected to the bottom panel, and at least one end closure.

  • Each side end flap also includes a reinforcing panel having a reinforcing edge, the reinforcing panel being foldable to place its reinforcing edge in reinforcing proximity to the cutouts in the respective side end flaps and overlay panels, thereby creating a notched cutout that is three plies thick along the hand-engaging portion.

  • FIG. 1 to manufacture the first exemplary carton 200, blank 100 is cut from a single sheet of the foldable sheet material, although it is contemplated that the blank 100 may include several separate panels that are secured together.
  • the inside surface the blank 100 is shown.
  • the blank 100 includes four major panels, namely, a top panel 102, a first side panel 104, a bottom panel 106, and a second side panel 108.
  • the panels 102, 104, 106, 108 are hingedly connected to one another along the length of the blank. More specifically, a side edge of top panel 102 is hingedly connected along fold line 110 to a side edge of first side panel 104. A side edge of first side panel 104 is hingedly connected along fold line 112 to a side edge of bottom panel 106. A side edge of bottom panel 106 is hingedly connected along fold line 114 to a side edge of second side panel 108.
  • the other side edge of top panel 102 is hingedly connected along fold line 118 to an edge flap 116, although any means for securing the second side panel 108 to the top panel 102 together may be used.
  • Each of the panels 102, 104, 106, 108 is also hingedly attached at each end edge thereof to end flaps for forming end closures at each end of the erected carton 200, as will be described in greater detail below.
  • Top panel 102 is hingedly connected to top end flaps 120a, 120b at end edges defined by fold lines 122a, 122b.
  • First side panel 104 is hingedly connected to first side end flaps 124a, 124b along end edges defined by fold lines'! 26a, 126b.
  • Bottom panel 106 is hingedly connected to bottom end flaps 128a, 128b along end edges defined by fold lines 130a, 130b.
  • Second side end panel 108 is hingedly connected to second side end flaps 132a, 132b along end edges defined by fold lines 134a, 134b.
  • top end flaps 120a, 120b include handle openings 136a, 136b; first side end flaps 124a, 124b include handle openings 144a, 144b; and second side end flaps 132a, and 132b include handle openings 152a, 152b, respectively.
  • Each of the handle openings 136a, 136b, 144a, 144b, 152a, 152b is an aperture defined by an endless edge (138a, 138b, 150a, 150b, 154a, 154b, respectively) that defines an ergonomic shape suitable for receiving the fingers of a user's hand so that the carton 200 can be lifted and carried easily.
  • the shape chosen includes an upper arch that conforms to the fingers of a hand.
  • the upper arch is defined by fold lines 142a, 142b, 148a, 148b, 158a, 158b, which enable cushioning flaps 140a, 140b, 146a, 146b, 156a, 156b to fold inward to cushion the fingers of the user's hand.
  • Each handle opening 136a, 136b, 144a, 144b, 152a, 152b is elongated so as to have an axis of elongation A, A', A".
  • the axes of elongation A of the handle openings 136a, 136b in the top end flaps 120a, 120b are substantially parallel to the end edges of the top panel 102 as defined by fold lines 122a, 122b, although it is contemplated that axes A may be disposed at an angle with respect to fold lines 122a, 122b.
  • the axes of elongation A' of the handle openings 144a, 144b in the first side end flaps 124a, 124b are substantially perpendicular to the axes of elongation A, and thus in the exemplary embodiment, are also perpendicular to the end edges of the first side panel 104 as defined by fold lines 126a, 126b.
  • the axes of elongation A" of the handle openings 152a, 152b in the second side end flaps 132a, 132b are also substantially perpendicular to the axes of elongation A, and thus in the exemplary embodiment, are similarly perpendicular to the end edges of the second side panel 108 as defined by fold lines 134a, 134b.
  • Each set of handle openings 136, 144, 152 also has a lateral axis B, B', B" that is perpendicular to axis of elongation A, A', A", the handle openings being symmetrical about the lateral axes.
  • handle openings 136a, 144a, 152a have complementary shapes, dimensions, and positions so as to be placed in registry with one another when the end flaps 120a, 124a, 132a are folded to overlie, overlap, or abut one another to form a first end closure 210 (shown in FIG. 3).
  • handle openings 136b, 144b, 152b are complementarily shaped, dimensioned, and positioned so as to be placed in registry with one another when end flaps 120b, 124b, 132b are folded to overlie, overlap, or abut one another to form a second end closure 212 (shown in FIG. 3).
  • the dimensions and shapes of the end flaps 120a, 124a, 132a also correlate to be foldable to provide a composite end closure 210 with a reinforced end handle H.
  • the width X of first side end flaps 124a, 124b and second side end flaps 132a, 132b, as defined by the distance from fold lines 126a, 126b, 134a, 134b to the outer edges of the respective end flap is no greater than the lesser of either the length Y of the end edges of top panel 102, as defined by fold lines 122a, 122b or the length Z of the end edges of the bottom panel 106, as defined by fold lines 130a, 130b.
  • the end edges of the bottom panel 106 may be substantially equal in length to the end edges of the top panel 102, thereby creating a carton with a substantially rectangular tubular cross section.
  • the end edges of top panel 102 may differ in length from the end edges of bottom panel 106, thereby creating an carton with a substantially trapezoidal cross section or a gabled tubular cross section (not shown) having shoulders, as is known in the art.
  • the trapezoidal or gabled cross section with a relatively larger base is particularly useful to enclose tapered articles such as beer bottles.
  • the exemplary carton 200 may be erected around an article or group of articles, or may be at least partially erected and then loaded and sealed. To facilitate an understanding of the configuration of the carton 200, one of potentially many contemplated techniques for erecting the carton 200 will now be described as a series of steps that may be performed substantially simultaneously or in any practical order, with some or all of the steps being performed either manually or automatically, such as by a packaging machine.
  • the exemplary process of erecting the carton is performed in two stages. The first stage is performed typically as part of the process of manufacturing the carton 200. In the first stage, a blank is cut, folded and then secured into a flattened tubular condition so that it can be shipped to a packing facility as a sleeve.
  • IPE plant equipment
  • the edges 138a, 138b, 150a, 150b, 154a, 154b of handle openings 136a, 136b, 144a, 144b, 152a, 152b may be defined by weakened severance lines enabling the center sections to be punched out, or the 138a, 138b, 150a, 150b, 154a, 154b may be defined by cut lines with the center sections being removed and discarded before the carton 200 is erected.
  • Each reinforcing panel 160a, 160b, 162a, 162b is defined by the end edge of respective side end flap 124a, 124b, 132a, 132b, to which the reinforcing panel 160a, 160b, 162a, 162b is connected along the respective fold line 164a, 164b, 166a, 166, which bisects the respective handle opening 144a, 144b, 152a, 152b, coinciding with the lateral axes thereof.
  • reinforcing panels may be separate pieces of sheet material that are applied as laminates to the side end flaps.
  • reinforcing panel 160a is folded so that its inside surface is in face contacting arrangement with the underlying portion of the inside surface of side end flap 124a; reinforcing panel 160b is folded so that its inside surface is in face contacting arrangement with the underlying portion of the inside surface of side end flap 124b; reinforcing panel 162a is folded so that its inside surface is in face contacting arrangement with the underlying portion of the inside surface of side end flap 132a; and reinforcing panel 162b is folded so that its inside surface is in face contacting arrangement with the underlying portion of the inside surface of side end flap 132b.
  • FIG. 3 is a cross-sectional view showing reinforcing panel 162a and side end flap 132a, to aid in understanding the relationship between each of the reinforcing panels and the respective side end flap.
  • the blank 100 is configured as shown in FIG. 2.
  • the handle openings 144a, 144b, 152a, 152b become doubly reinforced cutouts C.
  • the doubling of the material around each cutout C is demonstrated by the cross-sectional view of FIG. 3, which is taken along Ill-Ill in FIG. 2.
  • the first phase of the process is completed by applying adhesive or other securing means to the outside surface of edge flap 116, folding edge flap 116 so that its inside surface is in face contacting arrangement with the inside surface of top panel 102, and folding the entire blank 100 along fold line 112 so that the inside surface of top panel 102 is in face contacting arrangement with the inside surface of second side panel 108 and the outside surface of edge flap 116 is secured to the inside surface of second side panel 108.
  • the second stage of erecting the carton 200 may be performed at a bottling or packaging facility.
  • the flattened blanks 100 are loaded into a packaging machine, which in known fashion, disposes top panel 102 opposite bottom panel 106 and disposes first side panel 104 opposite second side panel 108 so that the carton 200 is configured as a tubular sleeve having a substantially rectangular as shown in FIG.4, although trapezoidal or gabled cross sections are also contemplated.
  • top panel 102 becomes top wall 202
  • first side panel 104 becomes first side wall 204
  • bottom panel 106 becomes bottom wall 206
  • second side panel 108 becomes second side wall 208.
  • first side panel 124a and second side panel 132a are folded toward the interior of the carton 200 until fold lines 164a and 166a abut or overlap slightly. In this manner, the cutouts C corresponding to handle openings 144a and 152a come together to approximate the dimensions of handle opening 136a. It should be noted that handle opening 136a may be relatively larger or smaller to account for slight variations in alignment. Adhesive is applied to the inside surface of bottom end flap 128a, and bottom end flap 128a is folded toward the interior of the carton 200 so that its inside surface is secured in a face contacting arrangement to the lower portions of the outside surfaces of side end flaps 124a, 132a.
  • top end flap 128a Adhesive is applied to the inside surface of top end flap 128a, and top end flap 128a is folded toward the interior of the carton 200 so that its inside surface is secured in a face contacting arrangement to the upper portions of the outside surfaces of side end flaps 124a, 132a.
  • Top end flap 120a may overlap bottom end flap 132a somewhat (as shown in FIG. 5), or conversely, bottom end flap 132a may overlap top end flap 120a.
  • each end closure 210, 212 includes a handle H, the edges of which are triply reinforced.
  • a portion of the periphery of the handle H as defined by edge 138a is substantially aligned with and reinforced by the doubled over edge 150a of handle opening 144a, and the remainder of the periphery of the handle H is substantially aligned with and reinforced by the doubled over edge 154a of handle opening 152a, making the area at or near all of the edges of the handle three plies thick.
  • Carton 700 is formed from blank 600 (FIG. 6), and embodies an alternative configuration that provides triple reinforcement of the handle H, while consuming even less sheet material.
  • carton 700 differs from carton 200 principally by the substitution of cutouts 652a, 652b, 644a, 644b for handle openings in the side end flaps 632a, 632b, 624a, 624b, and by the alternative configuration of reinforcing panels 660a, 660b, 664a, 664b, which are partially detached along respective severance lines 663a, 663b, 666a, 666b, folded along respective fold lines 662a, 662b, 667a, 667b (which lie along the upper edges of the respective side end flap) and secured in a face contacting arrangement with the underlying portion of respective side end panels 632a, 632b, 624a, 624b.
  • each of the reinforcing panels 660a, 660b, 664a, 664b is thereby placed in reinforcing proximity to the weight-bearing portion of cutout 652a, 652b, 644a, 644b.

Abstract

L'invention concerne une poignée renforcée fournie dans une fermeture de paroi d'extrémité d'un carton de type à manchon. Cette poignée est formée par une ouverture de poignée (636a) dans une fermeture-rabat supérieure (620a) et par alignement de l'ouverture de poignée avec des découpes correspondantes (644, 652a) constituées dans des fermetures-rabats latérales respectives (624a, 632a). Chaque découpe est renforcée par au moins un panneau de renforcement (664a, 660a) qui s'aligne au moins avec son bord de support de poids. Chaque panneau de renforcement est attaché de manière articulatoire à la fermeture-rabat latérale respective afin de pouvoir être plié le long du couplage articulé (667a, 662a) et fixé sur une face en contact avec l'ensemble, ce qui permet au panneau de renforcement de chevaucher la découpe comme un panneau de recouvrement ou d'aligner son bord avec le bord de support de poids de la découpe.
