That is to say starting from the respective vertex between a pair of adjacent linear portions of the cutting line defining the second orifice A8. The cut lines 47, 48 are divergently disposed relative to each other and define an angle therebetween, which may be about 22.5 degrees.

The second article holding structure RT2 includes a plurality of first circumferential cut lines 54. Each of the plurality of first circumferential cut lines 54 is aligned with one of the radial cut lines 47, 48 such that the one of the radial cut lines 47, 48 or an imaginary extension thereof bisects the respective one of the plurality of first circumferential cut lines 54.

Each of the plurality of first circumferential cut lines 54 is spaced apart from the one of the radial cut lines 47, 48 bisecting it to define a connecting gap or bridge portion between a pair of adjacently disposed teeth 46, 44. The connection notch or bridge portion is disposed proximate the base of the tooth 46.

The second article holding structure RT2 includes a plurality of second circumferential cut lines 42. Each of the plurality of second circumferential cut lines 42 is disposed between and spaced apart from a pair of the plurality of first circumferential cut lines 54 to define a pair of connection notches or bridge portions between each tooth 46, 44 and the main plate 12. The pair of connection notches or bridge portions provide a hinged or foldable connection between each tooth 46, 44 and the main panel 12.

The plurality of teeth 46, 44 are interrupted by a first recess or cut-out 56B, a second recess or cut-out 56C, and a third recess or cut-out 56A. The first and third recesses 56B, 56A are each located on a first imaginary line y-y. A first imaginary line y-y extends radially from the center C of the second aperture A8 and passes through the center of each of the first and third recesses 56B, 56A.

The first recess 56B is sized so as to occupy a first arc defined by the first secondary sector. The first secondary sector is defined in part by a first sector imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of the first partial tooth 44 disposed adjacent to a first side of the first recess 56B, and in part by a second sector imaginary line extending radially from the center of the imaginary circle and passing through a side edge of the second partial tooth 44 disposed adjacent to a second opposite side of the first recess 56B. The first and second sector imaginary lines define an angle therebetween. The angle may be in the range of 35 ° to 50 ° and may be around 45 °.

The second recess 56C is sized so as to occupy a second arc defined by a second secondary sector. The second minor sector is defined in part by a third sector imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of the third partial tooth 44 disposed adjacent to the first side of the second recess 56C, and in part by a fourth sector imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of the fourth partial tooth 44 disposed adjacent to the second opposite side of the second recess 56C. The third and fourth sector imaginary lines define an angle therebetween. The third angle may be in the range of 35 ° to 50 ° and may be around 45 °.

The third recess 56A is sized so as to occupy a third arc defined by a third secondary sector. The third secondary sector is defined in part by a fifth sector imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of the fifth partial tooth 44 disposed adjacent to the first side of the third recess 56A, and in part by a sixth sector imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of the sixth partial tooth 44 disposed adjacent to the second opposite side of the third recess 56A. The fifth and sixth sector imaginary lines define an angle therebetween. The third angle may be in the range of 35 ° to 50 °, and may be around 45 °.

The first and fifth sector imaginary lines define a primary sector or a first toothed sector, the first toothed sector defining a fourth arc; the fourth arc is occupied by teeth 46, 44. That is, the teeth 46, 44 are disposed about the fourth arc in a peripheral region of the second aperture A8.

The second and fourth sector imaginary lines define a third secondary sector or a second toothed sector, the second toothed sector defining a fifth arc; the fifth arc is occupied by teeth 46, 44. That is, the teeth 46, 44 are disposed about the fifth arc in a peripheral region of the second aperture A8.

The third and sixth sector imaginary lines define a fourth secondary sector or a third toothed sector, the third toothed sector defining a sixth arc; the sixth arc is occupied by teeth 46, 44. That is, the teeth 46, 44 are disposed about the sixth arc in a peripheral region of the second aperture A8.

The first and third recesses 56B, 56A are diametrically opposed to each other.

The second recess 56C is oriented or disposed substantially orthogonal to the first and third recesses 56B, 56A.

The centers of the first and third recesses 56B, 56A of the second article holding structure RT2 are collinear with the center of the first recess 56B of the first article holding structure RT 1.

The first recess 56B of each second article holding structure RT2 is disposed adjacent to and oriented opposite the first recess 56B of an adjacent one of the first article holding structures RT 1.

The third recess 56A of each second article holding structure RT2 is disposed adjacent to and oriented opposite the first recess 56B of an adjacent one of the first article holding structures RT 1.

The second recesses 56C of the second article holding structure RT2 are disposed close to each other and are oriented opposite to each other.

The second recess 56C of each first article holding structure RT1 is disposed adjacent to and oriented opposite the second recess 56C of the adjacently disposed first article holding structure RT 1.

The second article holding structure RT2 includes a first engagement tab T1 opposite the second recess 56C.

The first engagement tab T1 is disposed adjacent to the first or second side panel 18, 20. The first engagement tab T1 is integral with the main plate 12, that is to say the first and second circumferential cutting lines 42, 54 have been omitted. The first engagement tab T1 is adjacent to the fold lines 17, 19 hinging the main panel 12 to the respective side panels 18, 20.

The texture of the material forming the blank 10 may be arranged tangential to the center of the first and third recesses 56B, 56A of the second article retention feature RT 2. The texture of the material forming the blank 10 may be arranged tangential to the center of the first recess 56B of the first article retention feature RT 1. Thus, in order for the tear to propagate between the first aperture A7 and the second aperture A8, the tear must propagate across the texture of the blank 10. In this way, the blank 10 is arranged to provide maximum resistance to tear propagation between the first and second apertures A7, A8.

Removal of the teeth 46 by providing recesses 56B, 56C, 56A at a location where two adjacent apertures A7, A8 are disposed in close proximity has been found to reduce the likelihood of tear propagation, for example when packaging a smooth or elongate design of article B (article B having substantially the same diameter throughout its height-in some embodiments, the diameter variation between the top closure of article B and the body of article B may be less than 7mm, may be less than 5mm, and optionally less than 4 mm). This beneficial advantage may be the result of the removal of the radial cut lines 47, 48 in the region of the blank 210 where the apertures A7, A8 are very close.

The blank 10 may be applied to a group of articles B in a flat form and folded thereabout.

The main panel 12 is lowered relative to the group of articles B.

Each article retention feature RT1, RT2 of the blank 10 is aligned with a corresponding article B in the group. Part of the article B passes through the main panel 12. The toothed regions of the main panel 12 surrounding each article retention feature RT1, RT2 may fold out of the plane of the main panel 12.

Each toothed region of the main panel 12 may be folded around one of the articles B received in a respective one of the article retention structures RT1, RT 2. The main panel 12 may be deformed around an article B, such as, but not limited to, a shoulder portion of the article B, wherein the article B is a can, and the shoulder portion may be provided by a neck, as shown in fig. 3.

The engagement edges E1 of the teeth 44, 46 engage under the projections. The protrusion may be positioned around the neck or collar of the article B (which may provide a flange). When the article B is a can, the projection may be provided by an end seam of the can. In other embodiments, the engagement features or locations may be provided by a ridge or undercut formation of article B, or by an end closure of article B, such as, but not limited to, a crown cork or closure. In this way, the engagement edges grip or retain the article B and prevent or inhibit the article B from being accidentally separated from the main panel 12.

The first and second side panels 18, 20 are folded about opposite sides of a group of articles B. The corner panels 60A, 60B, 62A, 62B are folded around the corners of the group of articles B, and the securing panels 64A, 64B, 66A, 66B are folded around the ends of the group of articles B.

Glue or other adhesive treatment may be applied to the inner surfaces of the securing plates 64A, 64B, 66A, 66B or corresponding areas of the first and second end plates 14, 16.

The first and second end panels 14, 16 are folded downwardly about respective ends of a group of articles B. The first and second end plates 14, 16 are in face contacting relationship with respective ones of the fixed plates 64A, 64B, 66A, 66B. The first and second end plates 14, 16 are secured to respective ones of the securing plates 64A, 64B, 66A, 66B.

Fig. 2 and 3 show a package comprising an article carrier 90 and a group of articles B.

The carrier 90 may advantageously conceal a portion of the article B from view. The side panels 18, 20 and/or end panels 14, 16 may mask an area of the articles B, for example the panels 18, 20, 14, 16 may mask bar codes or other indicia such as, but not limited to, price markings provided on the respective articles B.

The side panels 18, 20 and end panels 14, 16 encircle or enclose a set of articles B and may contain or circumscribe the articles B; they may prevent or inhibit movement of the article B, such as tilting or splaying of the article B when the user is carrying the article carrier 90. The engagement of the side panels 18, 20 with the end panels 14, 16 via the securing panels 64A, 64B, 66A, 66B (and the corner panels 60A, 60B, 62A, 62B when present) may increase the strength, rigidity, and robustness of the carrier 90, such as when carrying the carrier 90 by engagement with one of the plurality of panels 12, 14, 16, 18, 20.

Fig. 3 illustrates the carrying handle in use, the carrying handle being at least partially formed by the first or second end panels 14, 16. Fig. 3 shows a user U engaging the first end plate 14.

The user U may insert one or more fingers into a gap or void between the first end plate 14 and a set of articles B, which void may be defined between the cylindrical sidewalls of a pair of adjacent articles B.

The severable line 13 separates the first end plate 14 from the main plate 12 when severed.

It will be appreciated that various modifications are possible within the scope of the invention, for example, the size and shape of the plates and apertures may be adjusted to accommodate articles of different sizes or shapes, greater or lesser numbers of articles, and/or articles arranged in different array configurations. While the foregoing embodiments have been illustrated and described with a "sunburst" article retention feature in which a plurality of tabs are disposed about an opening, other retention features may be employed. In other embodiments, the article retention features RT1, RT2 may take different forms, such as, but not limited to, an article receiving opening for receiving a portion of an article and providing a pair of opposed engagement edges for engaging opposed sides of the article under a flange, bead or other projection. It will be appreciated that in such embodiments, the top panel or engagement panel may be disposed at a height below the upper end of the packaged article.

The article retention features RT1, RT2 may take the form of a pair of spaced apart opposing cutouts defining displaceable areas forming a cover on the article and providing a pair of opposing engagement edges for engaging opposing sides of the article under a flange, bead or other projection.

It should be appreciated that directional references, such as "top," "bottom," "base," "front," "rear," "end," "side," "interior," "exterior," "upper" and "lower," as used herein do not necessarily limit the respective plates to such an orientation, but are merely used to distinguish the plates from one another.

As used herein, the terms "hinge connection" and "fold line" refer to all manner of lines that define the hinge features of the blank, facilitate folding portions of the blank relative to one another, or otherwise indicate the optimal panel folding position of the blank. Any reference to "hinged connection" should not be construed as necessarily referring to only a single fold line; in practice, the hinged connection may be formed by two or more fold lines, wherein each of the two or more fold lines may be straight/linear or curved/curvilinear in shape. When the linear fold lines form a hinged connection, they may be arranged parallel to each other or slightly angled relative to each other. When the curvilinear crease lines form a hinged connection, they may intersect one another to define a shaped panel in the area enclosed by the curvilinear crease lines. Typical examples of such hinged connections may include a pair of arcuate or curved fold lines intersecting at two points such that they define an elliptical plate therebetween. The hinged connection may be formed by one or more linear fold lines and one or more curvilinear fold lines. Typical examples of such hinged connections may include a combination of linear fold lines and arcuate or curved fold lines that intersect at two points such that a meniscus is defined therebetween.

As used herein, the term "polyline" may refer to one of the following: score lines, embossed lines, debossed lines, perforated lines, short slits, half-cut lines, single half-cut lines, intermittent cut lines, aligned slits, scored lines, and any combination of the foregoing.

It should be appreciated that the hinged connection and the fold line may each include elements formed in the base material of the blank, including perforations, perforation lines, short slit lines, half-cut lines, single half-cut lines, intermittent cut lines, slits, scores, embossed lines, debossed lines, any combination thereof, and the like. The elements may be sized and arranged to provide a desired function. For example, the perforation lines may be sized or designed with a degree of weakness to define fold lines and/or cut lines. The perforation lines may be designed to facilitate folding and resist breaking, to facilitate folding and to facilitate breaking with greater force, or to facilitate breaking with less force.

The phrase "aligned" 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 the two overlapping panels. Those elements that are aligned with each other may be aligned with each other in the thickness direction of the overlapping plates. For example, when an aperture in a first plate is "aligned" with a second aperture in a second plate, the second plate is placed in overlapping arrangement with the first plate, an edge of the aperture may extend along at least a portion of an edge of the second aperture, and may be aligned with the second aperture in a thickness direction of the first and second plates.
