Description

[Technical field]

[0001] The present invention relates to an article engaging structure, an article carrier, and a blank for forming the article carrier. More particularly, but not exclusively, the present invention relates to a top gripping type carrier having one or more openings for receiving and holding articles. [Background technology]

[0002] In the field of packaging, it is known to provide cartons for carrying multiple articles. Cartons are well known in the art and serve to allow consumers to transport, store, and access groups of articles for consumption. Due to cost and environmental considerations, such cartons or carriers need to be formed from as little material as possible and waste as little material as possible when formed. An additional consideration is the strength and suitability of the carton to hold and transport large weight articles. It is desirable for the contents of the carton to be stable within the carton.

[0003] It is well known to provide top gripping article carriers where an opening is formed in a panel of a carrier, and where a tab is cut from the panel and positioned around the opening such that when an article is received in the opening, the tab is displaced out of the plane of the panel, and the tab engages the article, generally around a flange or lip of the article.

[0004] It may be desirable to provide a cover to protect the top end of the item, or to provide a display panel for displaying information. Summary of the Invention [Problem to be solved by the invention]

The first end region 581 of the first slit 580a is disposed at a position radially inward of the second end region 583 of the second slit 580b. The intermediate region 582 of each of the first nonlinear slit 580a and the second nonlinear slit 580b forms a radially inner, distal, free, or engagement edge of at least one of the engagement teeth 540a, 540e, 540f.

[0159] The first end region 581 of the first slit 580a and the second end region 583 of the second slit 580b extend between them aligned with but spaced apart from one another to form a bridge strap 542 for connection between the cover panel 514 and the main panel 512 or, in an alternative embodiment, one of the engagement teeth 540a, 540e, 540f.

[0160] The bridge strap 542 comprises a first portion or section 542a extending generally circumferentially relative to the article receiving opening. The bridge strap 542 comprises a second portion or section 542b extending generally circumferentially relative to the article receiving opening and disposed radially outward of the first section 542a (i.e., the second portion or section 542b is further from the center of the article receiving opening than the first portion or section 542a). The first section 542a and the second section 542b are joined together by a third portion or section 542c, which extends generally radially relative to the article receiving opening. This arrangement may be advantageous to allow the main panel 512 to be spaced farther from the cover panel 514 (at a lower or higher elevation) when applied to an article without the bridge strap 542 having to extend radially significantly beyond the article receiving opening. In this manner, the article engaging structure RT has a compact footprint.

[0161] At least one of engagement teeth 540a, 540e, 540f has a side edge defined by a radial cut line 585 that extends generally radially relative to the article receiving opening. The radial cut line 585 extends from an intermediate region 582 of each one of the first nonlinear slit 580a and the second nonlinear slit 580b.

[0162] The first nonlinear slit 580a includes a diverging section 584 extending from a first end section 581 of the first nonlinear slit 580a. At least a portion of the diverging section 584 is disposed radially outwardly of and extends alongside a second end section 583 of the second slit 580b.

[0163] The cover panel 514 includes at least one stop tab 544 for resting on the article perimeter R (see FIG. 15 ). The at least one stop tab 544 extends radially outward from the cover panel 514 and is defined at least in part by a first end region 581 of the first nonlinear slit 580a. The illustrated embodiment includes four stop tabs 544, each defined by a first end region 581 of the nonlinear slit 580a.

[0164] The stopper tab 544 defines a recess in the bridge strap 542 that extends radially outward from the port C and may engage or receive a rim, ridge, protrusion, or lip that extends circumferentially at least partially around the port C. In this manner, the device 590 may be secured to the port C.

[0165] The main panel 512 of the device or keg ring 590 may be held over the top of the item B, barrel or keg (not shown in FIG. 15). The main panel 512 may not, at least initially, be in direct contact with the top of the item, although this may change as the device or keg ring 590 ages or absorbs moisture.

[0166] The engagement teeth 540a, 540e, 540f may be configured to engage a sidewall of port C to stabilize the device 590.

[0167] The present disclosure provides a top-engaging carrier 90; 190; 390; 490; 590 having article retaining or engaging structures RT; RT1, RT2 for engaging an article B with a blank 10; 110; 210; 310; 410; 510 to form an article carrier 90; 190; 390; 490; 590.

[0176] The blanks 10; 110; 210; 310; 410; 510 include at least a paperboard substrate. The paperboard substrate material may be selected from any conventional paperboard, for example, ranging in weight from about 10 pt. and up, preferably from about 16 pt. to about 28 pt. (0.028 in. / about 0.7 mm). Examples of such substrates are 27 point (pt.) SBS cardboard (a solid bleached sulfate board coated on one side under the trade name PrintKote®) or CNK® cardboard (Coated Natural Kraft® - an unbleached kraft board with a clay coat on one side under the trade name CarrierKote™) manufactured by the WestRock® Company. The paperboard substrate may be bleached or unbleached cardboard. The cardboard may be coated on at least one side, and optionally the side opposite the lamination, with a conventional coating selected for compatibility with the printing method and cardboard composition.

[0177] The blank 10;110;210;310;410;510 may include a tear-resistant layer laminated to the paperboard layer. The blank 10;110;210;310;510;610;710;810 may optionally include an adhesive layer between the paperboard substrate and the tear-resistant layer. The tear-resistant layer may be disposed over the uncoated side of the paperboard substrate and may be formed of a polymeric material and secured to the substrate. 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 n-axis oriented films such as MYLAR®, which are biaxially oriented polyester, oriented nylon, cross-laminated polyolefin, or high density polyolefin. The orientation and cross-lamination structure of these materials contribute to the tear resistance properties, which may also be attributed to the chemistry of the tear resistant materials, such as extruded metallocene-catalyzed polyethylene (mPE).

[0178] Alternatively, the tear resistant layer may be a layer of linear low density polyethylene (LLDPE). In embodiments where linear low density polyethylene (LLDPE) or mPE is used, it is not necessary to incorporate an adhesive layer. Other suitable materials having a high degree of tear resistance may be used.

[0179] The adhesive layer may be formed from a polyolefin material, such as low density polyethylene (LDPE). The adhesive layer may be disposed between the substrate and the tear resistant layer to secure the tear resistant layer to the substrate.

[0180] It will be understood that various modifications can be made within the scope of the invention. For example, the size and shape of the panels and openings can be adjusted to accommodate items of different sizes or shapes. Shoulder panels may be omitted. The invention is not limited to top-engaging types of cartons, and the invention may be used with other carton styles, such as, but not limited to, open top crates, lidded or closed top crates.

[0181] It will be appreciated that, as used herein, references to directions such as "top," "bottom," "bottom," "front," "back," "end," "side," "inward," "outward," "above," and "below" do not necessarily limit each panel to such orientation, but may merely serve to distinguish these panels from one another.

[0182] As used herein, the terms "hinge connection" and "fold line" refer to any manner of line that forms a hinge feature of the blank, facilitates folding portions of the blank relative to one another, or otherwise indicates the optimal location for folding a panel of the blank. References to "hinge connection" should not necessarily be construed as referring only to a single fold line, and in fact a hinge connection may be formed from two or more fold lines, each of which may be either straight / linear or curved / curved in shape. When linear fold lines form a hinge connection, they may be disposed parallel to one another or may be slightly angled relative to one another. When curved fold lines form a hinge connection, they may cross one another to form a shaped panel within the area enclosed by the curved fold line. A typical example of such a hinge connection may comprise a pair of arched or bowed fold lines that cross at two points to form an elliptical panel between them. The hinge connection may be formed from one or more linear fold lines and one or more curvilinear fold lines. A typical example of such a hinge connection may comprise a combination of a linear fold line and an arched or bowed fold line that intersect at two points to form a half-moon shaped panel therebetween.

[0183] As used herein, the term "fold line" may refer to one of the following: a perforation line, an embossed line, a debossed line, a perforation line, a short slit line, a half-cut line, a single half-cut, an interrupted cut, an aligned slit line, a perforation line, and any combination of the foregoing options.

[0184] It should be understood that each of the hinge connections and fold lines may each include elements formed in the blank substrate, including perforations, perforation lines, short slit lines, half-cut lines, single half-cuts, cuts, interrupted cuts, slits, perforations, embossed lines, debossed lines, any combination thereof, and the like. The elements may be sized and arranged to provide the desired functionality. For example, perforation lines may be sized or designed with a degree of weakness to form fold and / or tear lines. Perforation lines may be designed to facilitate folding while resisting tearing, to facilitate folding while facilitating tearing with greater effort, or to facilitate tearing with less effort.

[0185] The phrase "in registration with" as used herein refers to the alignment of two or more elements in an erected carton, such as an opening formed in a first of two overlapping panels and a second opening formed in a second of two overlapping panels. The elements that are in registration with one another may be aligned with one another in the thickness direction of the overlapping panels. For example, when an opening in a major panel is "in registration with" a second opening in a second panel that is placed in an overlapping arrangement with the major panel, an edge of the opening may extend along at least a portion of an edge of the second opening and may be aligned with the second opening in the thickness direction of the first and second panels.
