The blank 10 is folded about the fold line 19 such that the second side panel 20 is disposed in overlying relationship with the second end panel 18 and the securing panel 12 and a portion of the first side panel 16. The second side panel 20 is thereby secured to the securing panel 12.
The blank 10 is thus formed into a flat collapsed tubular structure which can be readily shipped or distributed to a convertor plant, at which the flat collapsed tubular structure may be erected into an open ended tubular structure and loaded with articles B.
The flat collapsed tubular structure may be erected to form an open ended tubular structure by unfolding the second side panel 20 with respect to the second end panel 18 such that the second side panel 20 is disposed substantially perpendicularly with respect to the second end panel 18.
The carton 90, in its open ended tubular form, may be loaded with articles B through one or both open ends thereof. That is to say, the carton may be top or bottom loaded by moving the carton 90 with respect to a group of one or more articles B. It will be appreciated that in some embodiments one of the open ends of the carton 90 may be closed before loading the interior with articles B through the remaining open end.
Once the carton 90 has been loaded with articles B the open ends of the carton 90 are closed. The gusset panels 30 a, 30 b, 32 a, 32 b are folded about fold lines 31 a, 31 b, 33 a, 33 b respectively so as to bend or deform upper portions of the first and second side panels 16, 20 inwardly. In this way the upper portions of the first and second side panels 16, 20 converge towards each other to form a gable top style carton.
A first, upper, end of the tubular structure is closed by folding the first top panel 22 a about fold line 23 a.
Glue or other adhesive treatment is applied to an outer surface of the first top panel 22 a, or in alternative embodiments to an inner surface of the second top panel 24 a.
The second top panel 24 a is folded about fold line 25 a so as to at least partially overlap with the first top panel 22 a. The second top panel 24 a overlies the first top panel 22 a. The second top panel 24 a is secured to the first top panel 22 a.
A second, lower, end of the tubular structure is closed by folding the second base panel 24 b about fold line 25 b.
In the illustrated embodiment the first bevel panel 26 and the second bevel panel 28 are folded with respect to the first and second side panels 16, 20 about fold lines 27, 29 respectively. In embodiments in which the first and second bevel panels 26, 28 are omitted, this step is omitted.
The first base panel 22 b is folded about fold line 23 b so as to at least partially overlap with the second base panel 24 b. The second base panel 24 b is disposed internally of the first base panel 22 b. The first base panel 22 b is secured to the second base panel 24 b by the complementary locking mechanisms. The male tabs M1, M2 are pressed out of the plane of the first base panel 22 b so as to displace the female tabs F1, F2 respectively. The male tabs M1, M2 pass through openings in the second base panel 24 b created by displacement of the female tabs F1, F2. The male tabs M1, M2 each comprises shoulders which are larger in dimension than the openings created by displacement of the female tabs F1, F2. In this way, the male tabs M1, M2 interlock the first base panel 22 b and the second base panel 24 b together.
In other embodiments alternative securing means may be employed to secure the first and second top panels 22 a, 24 a and/or the first and second bottom panels 22 b, 24 b for example, but not limited to, employment of mechanical locking devices such as staples. Additionally or alternatively the first and second base panels 22 b, 24 b may be adhesively secured to each other; the top panels 22 a, 24 a may be secured by one or more complementary locking mechanisms similar to those employed in the first and second base panels 22 b, 24 b.
A completed carton 90 is shown in FIG. 2. FIGS. 3, 4, 5 and 6 illustrate the access device in use. The carton 90 comprises an interior volume defined by the main panels 14, 16, 18, 20 forming the tubular structure, and the end closure panels 22 a, 24 a, 22 b; 24 b. The interior volume is loaded with articles B. The articles B are arranged in rows. The carton 90 can be carried by using the handle structure which is deployed by folding the first, second, third and fourth tabs 50 a, 50 b, 54 a, 54 b inwardly of the composite top wall 22 a/24 a about fold lines 52 a, 52 b, 55 a, 55 b respectively.
In order to dispense the articles B from the carton 90 a user U inserts a finger into one or both recesses R1, R2, as shown in FIG. 3, and pulls an upper portion of the second end panel 18 outwardly. The gusset panels 32 a, 32 b are folded about fold lines 33 a, 33 b respectively. The gusset panels 32 a, 32 b allow the upper portion of the second end panel 18 to be deformed and displaced outwardly so as to create an opening at the upper end of the carton 90. The user U continues to pull the upper portion of the second end panel 18 so as to sever the first severance line 17 a and the second severance line 19 a. The upper portion of the second end panel 18 can then be folded about fold line 35 to enlarge the opening, thereby facilitating access to the contents of the carton 90, as shown in FIG. 4.
The access device can be reclosed after use, as shown in FIGS. 5 and 6. The user U unfolds the upper portion of the second end panel 18 about the fold line 35. The user U manipulates the upper portion so as to insert said end portion of the second end panel 18 between upper portions of the first and second side panels 16, 20. The third and fourth gusset panels 32 a, 32 b fold about the fold lines 33 a, 33 b such that an inner surface of the third gusset panel 32 a is substantially in face contacting relationship with an inner surface of the first side panel 16. An inner surface of the fourth gusset panel 32 b is substantially in face contacting relationship with an inner surface of the second side panel 20.
The tab 60 folds about fold line 61. An end of the tab 60 engages with the aperture A4 so as to lock the upper portion of the second end panel 18 in position, as shown in FIG. 6. In some embodiments a portion of the tab 60 may pass through the aperture A4.
Referring now to FIGS. 7 to 12, there is shown an additional embodiment of the present disclosure. In the second illustrated embodiment, like numerals have, where possible, been used to denote like parts, albeit with the addition of the prefix “100” to indicate that these features belong to the second embodiment.

The blank 110 comprises an access device or dispenser D (see FIG. 8). The access device D comprises detachable portion 180, 182. A first detachable portion or part 180 is defined in the first top panel 122 a, and a second detachable portion or part 182 is defined in the second top panel 124 a. The first part 180 is defined in part by a first severance line 181 a and in part by a second severance line 181 b. The first severance line 181 a extends transversely across the first top panel 122 a. The second severance line 181 b is coincident with a portion of the fold line 123 a hinging the first top panel 122 a to the first side panel 116.
The second part 182 is defined in part by a third severance line 183 a and in part by a fourth severance line 183 b. The third severance line 183 a extends transversely across the second top panel 124 a. The fourth severance line 183 b is coincident with a portion of the fold line 125 a hinging the second top panel 124 a to the second side panel 120.
The second and fourth severance lines 181 b, 183 b may be replaced with fold lines such that the tear strip is partially detachable from the carton 190.
Optionally, the access device D may comprise one or more recesses for facilitating deployment of the access device D. The embodiment illustrated in FIG. 7 comprises a recess R1 struck from a free end edge of the first end panel 114 adjacent to the first top panel 122 a.
The carton 190 can be assembled, erected, loaded and closed in a similar manner to the method of construction previously described in relation to the embodiment of FIGS. 1 to 6. A completed carton 190 is shown in FIG. 8. FIGS. 9, 10, 11 and 12 illustrate the access device in use. The carton 190 comprises an interior volume defined by the main panels 114, 116, 118, 120 forming the tubular structure, and the end closure panels 122 a, 124 a, 122 b; 124 b. The interior volume is loaded with articles B. The articles B are arranged in rows.
In order to dispense the articles B from the carton 190 a user U tears away the tear strip 180, 182 so as to create an opening in the top of the carton 190 at one end thereof as shown in FIG. 9. The user then inserts a finger into the recess R1, as shown in FIG. 10, and pulls an upper portion of the first end panel 114 outwardly in direction Dl. The gusset panels 130 a, 130 b are folded about fold lines 131 a, 131 b respectively. The gusset panels 130 a, 130 b allow the upper portion of the second end panel 114 to be deformed and displaced outwardly so as to enlarge the opening at the upper end of the carton 190 and thereby facilitating access to the contents of the carton 190, as shown in FIG. 11.
The access device D can be reclosed after use, as shown in FIG. 12. The user U manipulates the upper portion of the first end panel 114 so as to insert said upper portion of the first end panel 114 between upper portions of the first and second side panels 116, 120. The first and second gusset panels 130 a, 130 b fold inwardly about the fold lines 131 a, 131 b respectively such that an inner surface of the first gusset panel 130 a is substantially in face contacting relationship with an inner surface of the second side panel 120 and/or the securing panel 112. An inner surface of the second gusset panel 130 b is substantially in face contacting relationship with an inner surface of the first side panel 116. In this way the opening can be reduced in size.
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”, “base”, “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” each refers to all manner of lines that define hinge features in a substrate of sheet material, for facilitating folding portions of the substrate with respect to one another, or otherwise for indicating optimal folding locations in the substrate. For example, a hinged connection should not be construed as necessarily referring to a single fold line only: indeed a hinged connection can be formed from one or more fold lines. A fold line may be, but not limited to, a single score line, a single half cut, a line of perforations, a line of short slits (i.e., an interrupted slit), a line of half-cuts, a line of cuts (i.e., an interrupted cut line), a series of short score lines (i.e., an interrupted score line), any combination thereof or the like.
As used herein, the term “severance line” refers to all manner of lines formed in a substrate of sheet material, that facilitate separating portions of the substrate from one another, or otherwise indicate optimal separation locations on the substrate. For example, a severance line in a substrate of sheet material is predisposed to allow a tear to propagate there-along. A severance line may be a frangible or otherwise weakened line which includes, but not limited to, a single cut, a single slit, a single half cut, a line of perforations, a line of short slits (i.e., an interrupted slit), a line of half-cuts, a line of cuts (i.e., an interrupted cut line), a series of short score lines (i.e., an interrupted score line), any combination thereof or the like. The elements of a fold line or severance line (such as cuts, scores and half cuts) may be dimensioned and arranged to provide the desired functionality.
It should be understood that hinged connections and severance 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 hinged connection such as a fold line and/or a severance line. The line of perforations can be designed to facilitate folding and resist breaking to provide a fold line, to facilitate folding and facilitate breaking with more effort to provide a severable or frangible fold line, or to facilitate breaking with little effort to provide a severance line.
The phrase “in registry with” as used herein refers to the 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, 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.
As used herein the term “recess” refers to all manner of shapings, cutaways, apertures, cuts, slots, holes and gaps which may be circular, rectangular, capsule shaped, irregularly shaped and many other shapes that facilitate a user grasping part of the dispenser or access device.
