[0120] The plurality of teeth 246, 244 are interrupted by a first recess or break 256B, a second recess or break 256C, and a third recess or break 256A. The first recess 256B and the third recess 256A are each located on a first imaginary line yy. The first imaginary line yy extends radially from the center C of the second aperture A3 and passes through the center of each of the first recess 256B and the third recess 256A.

[0121] The first recess 256B is sized to occupy a first circular arc defined by a first sub-arc.

[0122] The second recess 256C is sized to occupy a second circular arc defined by a second sub-arc. This second sub-arc is defined in part by a third sub-arc imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of a third partial tooth 244 disposed adjacent a first side of the second recess 256C, and in part by a fourth sub-arc imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of a fourth partial tooth 244 disposed adjacent a second, opposite side of the second recess 256C. The third sub-arc imaginary line and the fourth sub-arc imaginary line define an angle therebetween. This angle may be in the range of 35° to 50°, and may be approximately 45°.

[0123] The third recess 256A is sized to occupy a third circular arc defined by a third sub-arc. This third sub-arc is defined in part by a fifth sub-arc imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of the fifth partial tooth 244 disposed adjacent to a first side of the first recess 256A, and in part by a sixth sub-arc imaginary line extending radially from the center C of the imaginary circle and passing through a side edge of the sixth partial tooth 244 disposed adjacent to a second, opposite side of the first recess 256A. The fifth sub-arc imaginary line and the sixth sub-arc imaginary line define an angle therebetween. This angle may be between 35° and 50°, and may be approximately 45°.

[0124] The first and sixth segmental overhead lines define a main or first toothed segment, which defines a fourth arc, which is occupied by the teeth 246, 244. That is, the teeth 246, 244 are disposed along the fourth arc in the peripheral region of the apertures A3, A4, A5, A6.

[0125] The second and third sub-arc overhead lines define a fourth sub-arc or second toothed sub-arc, which defines a fifth arc, which is occupied by teeth 246, 244. That is, teeth 246, 244 are disposed along the fifth arc in the peripheral regions of apertures A3, A4, A5, A6.

[0126] The fourth and fifth sub-arc overhead lines define a fifth sub-arc or third toothed sub-arc, which defines a sixth arc, which is occupied by teeth 246, 244. That is, teeth 246, 244 are disposed along the sixth arc in the peripheral regions of apertures A3, A4, A5, A6.

[0127] The first recess 256B and the third recess 256A are located diagonally opposite each other.

[0128] The second recess is oriented or disposed substantially orthogonally to the first recess 256B and the third recess 256A.

[0129] The centers of the first recess 256B and the third recess 256A of each second item holding structure RT2 are aligned on the same straight line as the center of the first recess 256B of the adjacent first item holding structure RT1.

[0130] The first recess 256B of each second item holding structure RT2 is arranged near the first recess 256B of the adjacent first item holding structure RT1 and is oriented in the opposite direction to the first recess 256B of this first item holding structure RT1.

[0131] The second recess 256C of each second item holding structure RT2 is arranged near the second recess 256C of an adjacent second item holding structure RT2 in the same row and is oriented in the opposite direction to the second recess 256C of this second item holding structure RT2.

[0132] The second recess 256C of each first item holding structure RT1 is arranged near the second recess 256C of the adjacent first item holding structure RT1, and is arranged in the opposite direction to the second recess 256C of this first item holding structure RT1.

[0133] The web direction of the material forming the blank 210 may be tangential to the center of the first recess 256B and the third recess 256A of the second article retaining structure RT2. The web direction of the material forming the blank 210 may be tangential to the center of the first recess 256B of the first article retaining structure RT1. In this manner, for a tear to propagate between, for example, aperture A1 and aperture A3, the tear must propagate across the web direction of the blank 210. In this manner, the blank 210 is configured to provide maximum resistance to tear propagation between apertures A1 and A3.

[0134] It has been found that eliminating teeth 246 by providing recesses 256B, 256C, 256A at locations where two adjacent apertures A1, A2, A3, A4, A5, A6, A7, A8 are disposed in close proximity, such as when packaging article B2 with a smart or slim design, reduces the likelihood of tear propagation. This advantageous benefit may be the result of eliminating radial cut lines 248, 240 from areas of blank 210 where apertures A1, A2, A3, A4, A5, A6, A7, A8 are closest located.

[0135] In one example, the spacing d3, d4 between adjacent item retaining structures RT1, RT2 may be approximately 4.5 mm. The diameter d2 of the item receiving opening may be approximately 2.098 inches or 53 mm.

[0136] The centers C of these article-receiving openings are spaced apart by a distance S1, which is equal to or less than the maximum diameter D of the article B2. BS and the spacing between adjacent items B2. In one example, S1=D BS +3mm.

[0137] The main panel 212 may include optional handle structures H1 / H2 / H3, which may include at least one, at least two, or more handle openings. The illustrated embodiment includes three handle openings, each located in a central region between a first pair of adjacent item retaining structures RT1, RT2 and a second pair of adjacent item retaining structures RT1, RT2.

[0138] The first handle opening H1 may be substantially diamond-shaped or kite-shaped. The first handle opening H1 may be defined by a plurality of tabs, and in the illustrated embodiment, each of the two tabs is substantially triangular-shaped and hinged to the main panel 212 by a hinge connection in the form of a fold line. Each tab may include an additional fold line positioned to truncate the top end of the triangular-shaped tab. The tabs may be configured to fold substantially toward the center of the main panel 212.

[0139] The second handle opening H2 may be substantially square, although other shapes may be used, such as, but not limited to, a diamond or kite shape. The second handle opening H2 may be defined by a plurality of tabs, and in the illustrated embodiment, each of the four tabs is substantially triangular in shape and hinged to the main panel 212 by a hinge connection in the form of a fold line. Each tab may include an additional fold line positioned to truncate the top end of the triangular tab.

[0140] The third handle opening H3 may be substantially diamond-shaped or kite-shaped. This third handle opening H3 may be defined by a plurality of tabs, and in the illustrated embodiment, two tabs each have a substantially triangular shape and are hinged to the main panel 212 by a hinge connection in the form of a fold line. Each tab may include an additional fold line positioned to truncate the top end of the triangular tab. The tabs may be configured to fold substantially toward the center of the main panel 212.

[0141] Referring now to Figure 7, a further embodiment of the present disclosure is shown. In the illustrated fourth embodiment, like numerals are used to indicate like parts where possible, but are expressed as three digits beginning with "3" to indicate that these features belong to the fourth embodiment. This further embodiment shares many features in common with the first, second, and third embodiments, and therefore only the differences from the embodiments shown in Figures 1-6 will be described in detail.

[0142] FIG. 7 illustrates a fourth embodiment, showing a pair of frangible seam blanks 310A, 310B each with a main panel 312 for forming the top wall or engagement panel of a carrier (not shown).

[0143] The first blank 310A is severably connected to the second blank 310B by a severable connection 315. Each of the first blank 310A and the second blank 310B includes at least one item retention structure RT1. In the embodiment of FIG. 7, each main panel 312 includes a plurality of item retention structures RT1, specifically four item retention structures RT1 arranged in a 2×2 matrix or array. The main panel 312 includes two columns of item retention structures RT1, each column including two item retention structures RT1. The main panel 312 includes two rows of item retention structures RT1, each row including two item retention structures RT1. Each item retention structure RT1 may include an aperture A1, A2, A3, A4, A5, A6, A7, or A8.

[0144] The item retaining structure RT1 is substantially similar in construction to the first item retaining structure RT1 of the embodiment of Figure 5 and will not be described in further detail.

[0145] The centers C of the article-receiving openings in the first blank 310A are spaced apart by a distance S1, which is equal to or less than the maximum diameter D of the article B2. BS and the spacing between adjacent items B2. In one example, S1=D BS +3mm.

[0146] The centers C of the article-receiving openings in the second blank 310B are similarly spaced apart by a distance S1 (not shown), which is equal to or less than the maximum diameter D of the article B2. BS and the spacing between adjacent items B2. In one example, S1=D BS +3mm.

[0147] The center C of the item receiving opening in the first blank 310A is spaced a second distance S2 from the center of the item receiving opening in the second blank 310B. The second distance S2 is equal to or greater than the first distance S1 (S2≧S1). The distance S2 is determined by the distance between the maximum diameter D of the item B2 and the maximum diameter D of the item B2. BS and the spacing between the item B2 in the first carrier and the adjacent item B2 in the second carrier. In one example, S1=D BS +9mm.

[0148] In one example, the distances d3, d4 between adjacent item retaining structures RT1 may be about 4.5 mm.The diameter d2 of these item receiving openings may be about 53 mm.

[0149] The first blank 310A and the second blank 310B may each include an optional handle structure H1. The handle structure H1 may include a handle opening disposed in a central region between the first pair of adjacent item retaining structures RT1 and the second pair of adjacent item retaining structures RT1. The handle opening may be substantially diamond-shaped, although other shapes, such as, but not limited to, a square, may also be used. The handle opening may be defined by a plurality of tabs; in the illustrated embodiment, four tabs are each substantially triangular-shaped and hinged to the main panel 312 by a hinge connection in the form of a fold line. Each tab may include an additional fold line arranged to truncate the top end of the triangular-shaped tab.

[0150] The blanks 10, 110, 210, 310A, 310B each include at least a cardboard substrate. The cardboard substrate material may be selected from any conventional cardboard, ranging, for example, from about 10 point, preferably about 16 point, to about 28 point (0.028 inches, about 0.7 mm) in weight from lightest to lightest. An example of such a substrate is 24-point (pt.) SBS board (coated on one side with bleached sulfate cardboard, trade name PrintKote®) or CNK® board (Coated Natural Kraft®, unbleached kraft cardboard coated on one side with a clay coat, trade name CarrierKote™) manufactured by WestRock®. The cardboard substrate may be bleached or unbleached board. The board may be coated on at least one side, and optionally on the opposite side of the laminate, with a conventional coating selected for compatibility with the printing method and board composition.

[0151] The blanks 10, 110 may include a tear-resistant layer laminated to the cardboard layer. Optionally, the blanks 10, 110 include an adhesive layer between the cardboard base layer and the tear-resistant layer. The tear-resistant layer may be disposed over the uncoated surface of the cardboard base layer and may be formed from a polymeric material and secured to the cardboard base layer. The tear-resistant layer provides toughness to the laminate structure. Suitable tear-resistant materials may include, but are not limited to, tear-resistant laminate sheet materials such as NATRALOCK®, which may include layers of biaxially oriented polyester, oriented nylon, cross-laminated polyolefin, or n-axially oriented film such as MYLAR®, a high-density polyolefin. The oriented and cross-laminated structures of these materials contribute to their tear-resistant characteristics. Additionally, tear resistance may also be due to the chemical properties of the tear-resistant material, such as extruded metallocene-etched polyethylene (mPE).

[0152] Alternatively, the tear-resistant layer may be a linear low-density polyethylene (LLDPE) layer. In embodiments where linear low-density polyethylene (LLDPE) or mPE is used, there is no need to incorporate an adhesive layer. Other suitable materials with a high level of tear resistance may also be used.

[0166] It will be understood that various modifications 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 items of different sizes or shapes. Inner and / or outer shoulder panels may be omitted entirely or provided in any desired combination. The present invention is not limited to top-engaging type cartons and may be used with other cartons, such as, but not limited to, open-top crates, lidded or closed-top crates, and fully closed cartons.

[0167] It will be understood that directional terms used herein, such as "top," "bottom," "bottom," "front," "rear," "end," "side," "inner," "outer," "above," and "below," do not necessarily limit the respective panels to such orientations, but may merely serve to distinguish these panels from one another.

[0168] As used herein, the terms "hinge connection" and "fold line" refer to any manner of line that defines a hinge feature in a blank, facilitates folding of portions of the blank relative to one another, or otherwise suggests an optimal panel fold location in the blank. Any reference to a "hinge connection" should not be construed as necessarily referring to only a single fold line; in fact, a hinge connection can be formed from two or more fold lines, each of which can be either straight or curved in shape. When straight fold lines form a hinge connection, the fold lines may be disposed parallel to one another or at a slight angle relative to one another. When curved fold lines form a hinge connection, the fold lines may intersect one another to define shaped panels within the areas enclosed by the curved fold lines. A typical example of such a hinge connection may include a pair of arched or arcuate fold lines intersecting at two points to define an oval panel therebetween. A hinge connection may be formed from one or more straight fold lines and one or more curved fold lines. A typical example of such a hinge connection may consist of a combination of straight fold lines and arched or arcuate fold lines intersecting at two points to define a half-moon shaped panel therebetween.

[0169] As used herein, the term "crease line" may refer to one of the following: perforation line, embossed line, debossed line, perforation line, short slit line, half cut line, single half cut, interrupt cut line, aligned slit line, score line, and any combination of the foregoing options.

[0170] It should be understood that the hinge connections and fold lines may each include elements formed in the base layer of the blank, including perforations, perforation lines, short slit lines, half-cut lines, single half-cuts, cut lines, interstitial cut lines, slits, scores, embossed lines, debossed lines, and any combination thereof. These elements may be sized and positioned to achieve the desired functionality. For example, perforation lines may be sized or designed to have a degree of weakness that defines fold and / or division lines. These perforation lines can be designed to encourage folding and prevent breaking, to encourage folding and encourage greater breaking effort, or to encourage breaking with very little effort.

[0171] As used herein, the phrase "in registration with" 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. Elements that are in registration with one another may be aligned with one another in the thickness direction of the overlapping panels. For example, if an aperture in a first panel is "in registration with" a second aperture in a second panel that is in an overlapping configuration with the first panel, the edge of the former aperture may extend along at least a portion of the edge of the second aperture and be aligned with the second aperture in the thickness direction of the first and second panels.
