Turning to the construction of the carton 90 as illustrated in FIG. 3, the carton 90 can be formed by a series of sequential folding operations in a straight line machine so that the carton 90 is not required to be rotated or inverted to complete its construction. The folding process is not limited to that described below and may be altered according to particular manufacturing requirements.
The blank 10 is folded about fold line 15, such that the glue panel 12 and base panel 14 are folded thereabouts. The base panel 14 is brought into face contacting relationship with the first side panel 16; the glue panel 12 is brought into face contacting relationship with the top panel 18.
Glue or other adhesive treatment is applied to the glue panel 12 or, in alternative embodiments, to a corresponding portion of the second side panel 20.
The second side panel 20 is folded about the fold line 19 such that the second side panel 20 overlies the glue panel 12.
The second side panel 20 is secured to the glue panel 12 to form a flat collapsed carton. The carton 90 may be shipped or distributed in this flat collapsed form.
In alternative embodiments the second side panel 20 may be secured to the glue panel 12 by alternative securing means for example, but not limited to, staples or other mechanical fixing means.
The flat collapsed carton 90 may be erected into a tubular structure by separating the top panel 18 from the base panel 14.
The carton 90, in its open ended tubular form, may be loaded with articles C through one or both open ends. It will be appreciated that in other embodiments one of the open ends of the carton 90 may be closed before loading the carton 90 with articles C through the remaining open end.
In some embodiments, some or all of the end closure panels 22 a, 24 a, 26 a, 28 a, 30 a, 22 b, 24 b, 26 b, 28 b, 30 b are folded outwardly to form a funnel at one or both ends of the carton 90. This facilitates loading of the articles C into the carton 90 and reduces the risk of the end closure panels 22 a, 24 a, 26 a, 28 a, 30 a, 22 b, 24 b, 26 b, 28 b, 30 b interfering with the articles C when they are being loaded.
Once the carton 90 is loaded with articles C the ends of the tubular structure are closed.
A first end of the tubular structure is closed by folding the second and third end closure panels 24 a, 28 a about fold lines 25 a, 29 a respectively. The first and second gusset panels 26 a, 30 a are folded about fold lines 27 a, 31 a respectively.
Glue or other adhesive treatment is applied to the second end closure panel 24 a or in alternative embodiments to a corresponding portion of the first end closure panel 22 a.
Glue or other adhesive treatment is applied to the third end closure panel 28 a or in alternative embodiments to a corresponding portion of the first end closure panel 22 a.
The first end closure panel 22 a is then folded about the fold line 23 a to be brought into contact with the second and third end closure panels 24 a, 28 a and secured thereto.
A second end of the tubular structure is closed by folding the fifth and sixth end closure panels 24 b, 28 b about fold lines 25 b, 29 b respectively. The third and fourth gusset panels 26 b, 30 b are folded about fold lines 27 b, 31 b respectively.
Glue or other adhesive treatment is applied to the fifth end closure panel 24 b or in alternative embodiments to a corresponding portion of the fourth end closure panel 22 b.
Glue or other adhesive treatment is applied to the sixth end closure panel 28 b or in alternative embodiments to a corresponding portion of the fourth end closure panel 22 b.
The fourth end closure panel 22 b is then folded about the fold line 23 b to be brought into contact with the fifth and sixth end closure panels 24 b, 28 b and secured thereto.
In this way a secondary package is formed from the carton 90 and a group of articles C. The carton 90 comprises a handle structure H which extends transversely across the carton 90, between the first and second side walls 16, 20. Preferably, the upper ends of the articles C are tapered or beveled in shape such that a void exists between an upper portion of the first and second side walls and the adjacent articles C. This void allows the ends of the handle strap S to move inwardly of the carton 90 when a user grasps the grip element of the handle strap S. In this way a central portion of the handle strap comprising the grip element can be displaced upwardly with respect to a remainder of the top panel 18. Displacing the grip element upwardly provides a gap or space between the upper ends of the articles C and the handle strap S; a user can insert their hand or fingers into this space so as to comfortably carry the carton 90 and its contents. The upward displacement of the central portion of the handle strap is facilitated by the pairs of fold lines 42 a, 42 b, 44 a, 44 b, 46 a, 46 b, 48 a, 48 b. When the handle strap is in use the carton 90 folds about the pairs of fold lines 42 a, 42 b, 44 a, 44 b, 46 a, 46 b, 48 a, 48 b such that the handle strap S can be displaced upwardly.
Preferably, the ends of the cut lines 43 a, 43 b, 43 c, 43 d disposed in the respective one of the first or second side panels 16, 20 are arranged to terminate adjacent to a side wall of an article C disposed in the carton 90. In this way each of the ends of the cut lines 43 a, 43 b, 43 c, 43 d disposed in the respective one of the first or second side panels 16, 20 is in contact with an article C, or each end can be brought into contact with an article C when the handle structure H is in use. In this way the article C provides strength or reinforcement to the handle structure H to mitigate against, or prevent, tears propagating in the material forming the carton 90. Preferably the articles C are arranged in rows within the carton 90; the end of the cut line 43 a in the first side panel 16 and the end of the cut line 43 b in the second side panel 20 are configured to be aligned with articles in the same row as each other such that said entire row of articles C forms a brace therebetween. The end of the cut line 43 c in the first side panel 16 and the end of the cut line 43 d in the second side panel 20 are configured to be aligned with articles in the same row as each other such that that entire row of articles C forms a brace therebetween.
FIG. 4 shows stages in the production of a tertiary package 190 (see FIG. 5) from a pair of secondary packages 90A, 90B and a second blank 110. In a first stage, a pair of secondary packages 90A, 90B are stacked one on top of another, the base panel 14 of a first secondary package 90A being placed upon the top panel 18 of a second secondary package 90B to form a group of secondary packages 92.
In a second stage the second blank 110 is wrapped about the group of secondary packages 92. An inner surface of the outer top panel 114 of the first blank 110 is placed in face contacting relationship with an outer surface of the top panel 18 of the first secondary package 90A.
The first, second, third and fourth gusset panels 128 a, 132 a, 128 b, 132 b are then folded so as to be in face contacting relationship with an inner surface of the respective one of the first and second outer side panels 112, 116 to which they are hinged. In doing so the first and second end closure panels 120 a, 120 b are folded about the fold lines 121 a, 121 b respectively.
Glue or other adhesive treatment is applied to the first outer side panel 112 or in alternative embodiments to a corresponding portion of the first side panel 16 of the second secondary package 90B.
Glue or other adhesive treatment is applied to the second outer side panel 116 or in alternative embodiments to a corresponding portion of the second side panel 20 of the second secondary package 90B.
The first and second outer side panels 112, 116 are then folded about fold line 113, 115 respectively to be brought into face contacting relationship with the opposing sides of the group of secondary packages 92.
The first and second outer side panels 112, 116 are secured to the second secondary package 90B to form the tertiary package shown in FIG. 5.
The handle apertures A3, A4 provided in the outer top panel 114 are in registry with one of the first and second apertures A1, A2 of the first secondary package 90A. The tertiary package can be carried by simultaneously engaging the handle apertures A3, A4 and the first and second apertures A1, A2 as shown in FIG. 6. In this way, the carrying handle comprises two layers or plies, a first portion or ply provided by the secondary package 90A and a second portion or ply provided by the tertiary carton. Thus the strength of the carrying handle is increased.
It will be appreciated that the outer end closure panels 120 a, 120 b retain the first secondary package 90A within the tertiary package 190, preventing the first secondary package 90A from moving (sliding) with respect to the tertiary package 190 or the second secondary package 90B.
The second secondary package 90B can be separated from the first secondary package 90A by tearing the first and second tear strips T1, T2 as shown in FIG. 7. When the tear strips T1, T2 have been detached from the tertiary package an upper portion of the tertiary carton formed by the second blank 110 can be removed from the first secondary package 90A, since the second blank is unsecured to, or free from, the first secondary package 90A.
It can be appreciated that various changes may be made within the scope of the present invention; for example, the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape.
It will be recognised that as used herein, directional references such as “top”, “bottom”, “front”, “back”, “end”, “side”, “inner”, “outer”, “upper” and “lower” do not necessarily limit the respective panels to such orientation, but may merely serve to distinguish these panels from one another.
As used herein, the terms “hinged connection” and “fold line” refer to all manner of lines that define hinge features of the blank, facilitate folding portions of the blank with respect to one another, or otherwise indicate optimal panel folding locations for the blank. A fold line is typically a scored line, an embossed line, or a debossed line. Any reference to “hinged connection” or “fold line” should not be construed as necessarily referring to a single fold line only; indeed the hinged connection can be formed from any one or more of the following: a short slit, a frangible line or a fold line without departing from the scope of the invention.
As used herein, the term “severance line” refers to all manner of lines that facilitate separating portions of the substrate from one another or that indicate optimal separation locations. Severance lines may be frangible or otherwise weakened lines, tear lines, cut lines, or slits.
It should be understood that hinged connection, severance lines and fold lines can each include elements that are formed in the substrate of the blank including perforations, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, a cut line, an interrupted cut line, slits, scores, any combination thereof, and the like. The elements can be dimensioned and arranged to provide the desired functionality. For example, a line of perforations can be dimensioned or designed with degrees of weakness to define a fold line and/or a severance line. The line of perforations can be designed to facilitate folding and resist breaking, to facilitate folding and facilitate breaking with more effort, or to facilitate breaking with little effort.
The phrase “in registry with” as used herein refers to alignment of two or more elements in an erected carton, such as an aperture formed in a first of two overlapping panels and a second aperture formed in a second of two overlapping panels. Those elements in registry with each other may be aligned with each other in the direction of the thickness of the overlapping panels. For example, when an aperture in a first panel is “in registry with” a second aperture in a second panel that is placed in an overlapping arrangement with the first panel, and an edge of the aperture may extend along at least a portion of an edge of the second aperture and may be aligned, in the direction of the thickness of the first and second panels, with the second aperture.
