Description

TECHNICAL FIELD

The present invention relates to carriers and to blanks for forming the same. More specifically, but not exclusively, the invention relates to a carrier having a partition structure feature defining cells or compartments within an interior of a carrier of the basket-style.

BACKGROUND

In the field of packaging, it is known to provide article carriers or cartons for carrying multiple articles. Cartons are well known in the art and are useful for enabling consumers to transport, store and access a group of articles for consumption. For cost and environmental considerations, such cartons or carriers need to be formed from as little material as possible and cause as little wastage in the materials from which they are formed as possible. Further considerations are the strength of the carton and its suitability for holding and transporting large weights of articles. It is desirable that the contents of the carton are secure within the carton.
It is an object of the present invention to provide to a carrier having a partition structure for separating articles within an interior chamber of the carrier. It is desirable to minimise or reduce the material required to produce the carrier for economic or environmental benefit or both.
It is desirable that the blank from which the carrier is formed can be readily assembled into a carrier in a simple and efficient manner.
The present invention seeks to provide an improvement in the field of cartons, typically formed from paperboard or the like.

The distal portion 66B of the second partition panel 66 comprises a weakened line 79 spaced apart from fold lines 77, 83 and parallel thereto. The weakened line 79 is offset, inset from, the outer or free end E1 of the second partition panel 66 defined by the outermost portion of cutline 75. The weakened line 79 may be formed from one or more elements and may comprise a perforation, at least one cut or half cut, at least one opening, aperture, slot or slit, or may comprises at least one crease line or any combination of these features.
The second glue panel 68 is defined, at least in part, by a cutline 71, cutline 71 is substantially "U" or "C" shaped. The cutline 71 extends from the fold line 77 and comprises terminal ends, disposed proximate or adjacent to the free end E1 of the second partition panel 66, which terminal ends generally lie on, or intersect, a notional line N1 that is collinear, coincident or coextensive with the fold line 77. The notional line N1 is spaced apart from and parallel to the fold line 69 hinging the second partition panel 66 to the first medial panel 14. The notional line N1 is spaced apart from the free end E1 of the second partition panel 66 by greater distance than the weakened line 79.
The second glue panel 68 comprises a bridging or connection portion 68B defined in part by fold line 83 and a second fold line 81 spaced apart and parallel thereto. The connection portion 68B couples a securing portion or main body of the second glue panel 68 to the distal portion 66B of the second partition panel 66.
The first medial panel 14 may comprise a raised or embossed region EB raises a surface of the first medial panel 14 such a that a secure bond between the first medial panel 14 and the second handle reinforcing panel 34, with which it is disposed in face-to-face relationship with, can be formed.
The first medial panel 14 may comprise one or more embossed or crease lines EL, the embossed lines EL may increase the rigidity of the region of the first medial panel 14 in which the are formed, said region may be define a portion of the medial structure or divider which is single ply in construction. The second medial panel 28 may be shorter in width than the first medial panel 14. The first medial panel 14 extends fully between opposed end walls of the carrier 90. The second medial panel 28 extends only a portion of the way between opposed end walls of the carrier 90. This arrangement avoids requiring the second medial panel 28 to be disposed in an overlapping or overlying relationship with the securing panel 12 during construction of the carrier 90, best shown in Figure 4A. This limits the flat collapsed carrier 90F to having a four ply or four layer structure or arrangement and avoids creating a five play or layer section in the region of the securing flap 12.
Fold line 69 defines an inner end of the second partition panel 66. The fold line 77 and the fold line 69 define a second linear dimension L2 therebetween. The second linear dimension L2 is less than the first linear dimension L1.

The present invention is not limited to cartons of the basket carrier style, the invention may be employed with other carton styles such as, but not limited to, open top crates, lidded or closed top crates and fully enclosed cartons.
In one embodiment the medial panel may omitted, the partition structure may be formed from a first one of a pair of opposing wall panels, the opposing wall panels defining in part an interior of the carrier. The partition structure may divide the interior into two or more article receiving cells. The partition structure may comprise a lateral partition panel hingedly connected at a proximal end to said first one of the pair of opposing wall panels by proximal end fold line and at its distal end to a glue panel by a distal end joint, the glue panel being secured to the second one of the pair of opposing wall panels.
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" 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. Any reference to "hinged connection" should not be construed as necessarily referring to a single fold line only; indeed, a hinged connection can be formed from two or more fold lines wherein each of the two or more fold lines may be either straight/linear or curved/curvilinear in shape. When linear fold lines form a hinged connection, they may be disposed parallel with each other or be slightly angled with respect to each other. When curvilinear fold lines form a hinged connection, they may intersect each other to define a shaped panel within the area surrounded by the curvilinear fold lines. A typical example of such a hinged connection may comprise a pair of arched or arcuate fold lines intersecting at two points such that they define an elliptical panel therebetween. A hinged connection may be formed from one or more linear fold lines and one or more curvilinear fold lines. A typical example of such a hinged connection may comprise a combination of a linear fold line and an arched or arcuate fold line which intersect at two points such that they define a half-moon shaped panel therebetween.
As used herein, the term "fold line" may refer to one of the following: a scored line, an embossed line, a debossed line, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, an interrupted cutline, a line of aligned slits, a line of scores and any combination of the aforesaid options.
It should be understood that hinged connections 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 cutline, an interrupted cutline, 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 or a severance line or both. 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 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.
