Description

TECHNICAL FIELD

The present disclosure relates to article carriers and to blanks for forming the same. More specifically, but not exclusively, the disclosure relates to a carrier of the top-gripping type having one or more apertures for receiving and retaining an article therein.

BACKGROUND

In the field of packaging, it is known to provide 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 well known to provide top gripping article carriers in which an aperture is formed in a panel of the carrier, wherein tabs are struck from said panel and are arranged about the aperture. The tabs are displaced out of the plane of said panel when an article is received in the aperture, wherein said tabs engage the article generally about a flange or lip of the article.

The present disclosure seeks to provide an improvement in the field of cartons, typically formed from paperboard or the like.

DETAILED DESCRIPTION OF EMBODIMENTS

Detailed descriptions of specific embodiments of the package, blanks and carriers are disclosed herein. It will be understood that the disclosed embodiments are merely examples of the way in which certain aspects of the disclosure can be implemented and do not represent an exhaustive list of all of the ways the disclosure may be embodied. As used herein, the word “exemplary” is used expansively to refer to embodiments that serve as illustrations, specimens, models, or patterns. Indeed, it will be understood that the packages, blanks and carriers described herein may be embodied in various and alternative forms. The Figures are not necessarily to scale and some features may be exaggerated or minimised to show details of particular components. Well-known components, materials or methods are not necessarily described in great detail in order to avoid obscuring the present disclosure. Any specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the disclosure.

Referring to FIG. 1, there is shown a plan view of a blank 10 which is capable of forming a carton or carrier (not shown), as shown in FIG. 2, for containing and carrying a group of primary products such as, but not limited to, bottles or cans, hereinafter referred to as articles B, as shown in FIG. 2. The articles B may be generally cylindrical; the articles B may comprise a circular cross-sectional shape, at least about a region of engagement with the carrier. The blank 10 forms a secondary package for packaging at least one primary product container or package. Alternative blanks 110; 210; 310; 410; 510; 610; 710; 810 are shown in FIGS. 3 to 9B for forming an alternative carton or carrier 190.

In the embodiments detailed herein, the terms “carton” and “carrier” refer, for the non-limiting purpose of illustrating the various features of the disclosure, to a container for engaging and carrying articles, such as primary product containers. It is contemplated that the teachings of the disclosure can be applied to various product containers, which may or may not be tapered and/or cylindrical. Exemplary containers include bottles (for example metallic, glass or plastics bottles), cans (for example aluminium cans), tins, pouches, packets and the like.

The blanks 10; 110; 210; 310; 410; 510; 610; 710; 810 are formed from a sheet of suitable substrate. It is to be understood that, as used herein, the term “suitable substrate” includes all manner of foldable sheet material such as paperboard, corrugated board, cardboard, plastic, combinations thereof, and the like. It should be recognised that one or other numbers of blanks may be employed, where suitable, for example, to provide the carrier structure described in more detail below.

The packaging structures or cartons described herein may be formed from a sheet material such as paperboard or corrugated board, which may be made of or coated with materials to increase its strength. An example of such a sheet material is E- or F-flute corrugated board. Another example may be tear-resistant NATRALOCK® paperboard made by WestRock Company. It should be noted that the tear resistant materials may be provided by more than one layer, to help improve the tear-resistance of the package. Typically, one surface of the sheet material may have different characteristics to the other surface. For example, the surface of the sheet material that faces outwardly from a finished package may be particularly smooth and may have a coating such as a clay coating or other surface treatment to provide good printability. The surface of the sheet material that faces inwardly may, on the other hand, be provided with a coating, a layer, a treatment or be otherwise prepared to provide properties such as one or more of tear- resistance, good glue-ability, heat sealability, or other desired functional properties.

In the illustrated embodiments, the blanks 10; 110; 210; 310; 410; 510; 610; 710; 810 are configured to form a carton or carrier 190 for packaging an exemplary arrangement of exemplary articles B. In the embodiments illustrated in FIGS. 1 to 5, the arrangement is a 2×2 matrix or array—two rows of two articles B are provided-and the articles B are beverage cans. In the embodiments illustrated in FIGS. 5A to 9B, the arrangement is a 2×4 matrix or array—two rows of four articles B are provided—and the articles B are beverage cans. Alternatively, the blanks 10; 110; 210; 310; 410; 510; 610; 710; 810 can be configured to form a carrier for packaging other types, number and size of articles and/or for packaging articles in a different arrangement or configuration.

Referring to FIG. 1, there is shown a blank 10 comprising a main panel 12 for forming a top wall or an engaging panel of a carrier (not shown).

The main panel 12 includes at least one article retention structure RT. In the illustrated embodiment, the main panel 12 comprises a plurality of article retention structures RT specifically four article retention structures RT arranged in 2×2 matrix or array. The main panel 12 comprises two columns of article retention structures RT, each column comprises two article retention structures RT. The main panel 12 comprises two rows of article retention structures RT, each row comprises two article retention structures RT. Each of the article retention structures RT may comprise an aperture A1.

Each of the article retention structures RT is substantially similar in construction and will therefore be described in detail with reference to a first one of the article retention structures RT located adjacent to a first end of the blank 10 as shown in FIG. 8A. The article retention structure RT comprises an article receiving opening defined in part by an aperture A1. The article retention structure RT comprises a perimeter or engaging edge E1 defined by the aperture A1. The perimeter E1 is a load bearing edge from which the article B is supported or suspended. The article retention structure RT may comprise at least one cutaway C1, C2, N1 struck from the perimeter of the aperture A1. However, the article retention structure RT of FIG. 8A comprises at least one first or major cutaway C1, C2 and at least one second or minor cutaway N1. The at least one first cutaway C1, C2 is larger than the at least one second cutaway N1. The at least one first cutaway C1, C2 comprises a first angular width or dimension θ1 as shown in FIG. 1. The at least one second cutaway N1 comprises a second angular width or dimension θ2 as shown in FIG. 1. The first angular width or dimension θ1 is greater than the second angular width or dimension θ2. The first angular width or dimension θ1 may be in the range 10° to 45°, may be in the range 20° to 40°, and may be about 31.25°. The second angular width or dimension θ2 may be less than 10°, may be in the range 5° to 30°, may be in the range 5° to 15°, and may be about 7.15°. The first angular width or dimension θ1 may be at least twice the magnitude of the second angular width or dimension θ2, may be between three to six times greater in magnitude, and may be about four times greater in magnitude. Those cutaways C1, C2, N1 reduce application force (or radial stress) which may be applied to the main panel 12 when the carrier blank is applied to articles such as cans. Application force is a critical converting parameter which may be improved significantly with the use of cutaways such as the cutaways C1, C2, N1. Reduction of application force or stress relief become important where tear initiations are likely, such as when the MD alignment of paperboard/corrugated board fibers aligns with the stress propagation vector. FIG. 1 shows an optional example of the locations of the first cutaways C1, C2 where those cutaways may effectively reduce application force on condition that one of notional lines X-X and Y-Y which bisect the cutaways C2, C1 respectively is parallel to the grain/fiber direction of the main panel 12 which may optionally be formed of paperboard or corrugated board.

Referring to FIG. 8A, the perimeter of the aperture A1 comprises four arcuate segments, each of which provides a load bearing edge. A first arcuate segment Sis defined by two circular cut lines each centred at a first centre C_e and having a first radius of curvature R_a. In one example, the first radius of curvature R_a may be around 1.001 inches or about 25.4 mm. The first arcuate segment S is interrupted by the at least one second cutaway N1.

A second arcuate segment S1 substantially diagonally opposes the second cutaway N1 and is defined by a circular cut line centred at a second centre C_e1 and having a second radius of curvature R_a1 defining a second circle C_r1. In one example, the second radius of curvature R_a1 may be around 1.3 inches or about 33 mm. The second centre C_e1 lies on a notional line passing through a corner of the main panel 12 (or a notional corner or vertex P defined by extensions of the side and end edges of the main panel 12) and the first centre C_e; said notional line may be arranged to define an angle of 45° with the side or end edge of the main panel 12. The second radius of curvature R_a1 is greater than the first radius of curvature R_a. The second arcuate segment S1 extends between a first major cutaway C1 and a second major cutaway C2.

A third arcuate segment S2 is disposed between the first major cutaway C1 and the first arcuate segment S and defines a transition between the first major cutaway C1 and the first arcuate segment S. The third arcuate segment S2 is defined by a circular cut line centred at a third centre C_e2 and having a third radius of curvature R_a2 defining a third circle C_r2. In one example, the third radius of curvature R_a2 may be around 1.3 inches or about 33 mm. The third radius of curvature R_a2 is greater than the first radius of curvature R_a. The third radius of curvature R_a2 may be equal to the second radius of curvature R_a1.

A fourth arcuate segment S3 is disposed between the second major cutaway C2 and the first arcuate segment S and defines a transition between the second major cutaway C2 and the first arcuate segment S. The fourth arcuate segment S3 is defined by a circular cut line centred at a fourth centre C_e3 and having a fourth radius of curvature R_a3 defining a fourth circle C_r3. In one example, the fourth radius of curvature R_a3 may be around 1.3 inches or about 33 mm. The fourth radius of curvature R_a3 is greater than the first radius of curvature R_a. The fourth radius of curvature R_a3 may be equal to the second radius of curvature R_a1.

FIG. 8A illustrates the position of an article B, in the illustrated embodiment a can, wherein the dashed line NC1 shows the position of the side wall of a main body portion of the article B and indicates the maximum diameter or width of the article B. The position of an upper rim or chime of the article B is indicated by dashed line NC2. When the carrier is applied to the article B, the upper rim of the article B passes through the opening in the main panel 12 provided by the article retention structure RT. The rim may be provided by an end seam such as a canners end seam. The rim comprises a radius of curvature R_b. In one example, the rim may have a diameter around 2.1235 inches or about 53.9 mm, the radius of curvature R_b being about 26.9 mm. The main body portion may have a diameter of around 2.6 inches or about 66 mm. The rim radius R_b is greater than the first radius of curvature R_a. The aperture A1 and the major and minor cutaways C1, C2, N1 are arranged to be disposed within the footprint of the upper rim of the article B, in FIG. 8A, the aperture A1 and the major and minor cutaways C1, C2, N1 are arranged to be disposed substantially within the circle NC2. In some embodiments, the second radius of curvature R_a1, third radius of curvature R_a2, and fourth radius of curvature R_a3 may be equal to the radius of curvature of the main body portion of the article B to be engaged, the distance between first centre C_e and notional circle NC1 shown in FIG. 8A.

A portion of the second arcuate segment S1 may be coincident or lie on a notional circle NC defined by the first arcuate segment S.

The second notional circle C_r1 and the third notional circle C_r2 intersect at a midpoint of the first major cutaway C1, the midpoint of the first major cutaway C1 and the first centre C_e defining a notional line NL1 perpendicular to a first or side edge “Se” of the main panel 12. The intersection between second circle C_r1 and the third circle C_r2 may lie upon an edge of the aperture A1 defined by the first cutaway C1. The intersection between second circle C_r1 and the third circle C_r2 may lie upon a vertex or intersection between the notional line NL 1 perpendicular to the side edge “Se” of the main panel 12 and the circle NC2 defining the location of the rim of the article B.

The second circle C_r1 and the fourth circle C_r3 intersect at a midpoint of the second cutaway C2, the midpoint of the second cutaway C2 and the first centre C_e defining a notional line NL2 perpendicular to a second or end edge “Ee” of the main panel 12. The intersection between second circle C_r1 and the fourth circle C_r3 may lie upon an edge of the aperture A1 defined by the second cutaway C2. The intersection between second circle C_r1 and the fourth circle C_r3 may lie upon a vertex or intersection between the notional line NL2 perpendicular to the end edge “Ee” of the main panel 12 and the circle NC2 defining the location of the rim of the article B.

The minor cutaway N1 is centred on a notional line NL4 passing through the first centre C_e and the corner of the main panel 12 (or a notional corner or vertex P defined by extensions of the side and end edges “Se”, “Ee” of the main panel 12).

The centres or midpoints of the first and second major cutaways C1, C2 are orthogonally arranged and are spaced equidistant about the notional line NL4 passing through a corner of the main panel 12 (or a notional corner or vertex P defined by extensions of the side and end edges “Se”, “Ee” of the main panel 12). Stated differently, the notional line NL4 defines an axis of symmetry about which the major cutaways C1, C2 are disposed symmetrically. In an alternative embodiment or optionally, the major cutaways C1, C2 may be asymmetrically arranged about the notional line NL4.

The opposite terminal ends of the first arcuate segment S define a notional line NL-NL; the notional line NL-NL defines locations on the perimeter E1 of the aperture A1 where the radius of curvature changes. Stated differently and as viewed in FIG. 8A, that portion of the perimeter E1 on the lower-right side of the notional line NL-NL comprises a first load bearing edge having the first radius of curvature Ra while that portion of the perimeter E1 on the upper-left side of the notional line NL-NL comprises a second load bearing edge having the second radius of curvature Ra1, Ra2 or Ra3. The first load bearing edge or first arcuate segment S is divided by the minor cutaway N1 into two portions. The second load bearing edge is divided by the first and second major cutaways C1, C2 into the three arcuate segments S1, S2, S3 having the respective (or different) centers Ce1, Ce2, Ce3 of curvature spaced apart from one another. The notional line NL-NL is disposed between the first centre C_e and the corner of the main panel 12 (or a notional corner or vertex P defined by extensions of the side and end edges of the main panel 12). The notional line NL-NL is disposed between the first centre C_e and the major cutaway C1, C2. In some embodiments, the notional line NL-NL may pass through the first centre C_e.

Referring again to FIG. 1, the minor cutaways N1 of the article retention structures RT are located about the apertures A1 at a location in closest proximity to an optional handle opening A2 forming a carrying handle H. The handle opening A2 is centrally struck from the main panel 12 and is disposed centrally of the group of four article retention structures RT provided in the main panel 12.

Optionally, each minor cutaway N1 may be defined by an arcuate edge having a radius of curvature. In an alternative embodiment or further optionally, each minor cutaway N1 may be defined by multiple linear edges angularly disposed with respect to each other to form, for example, a half a hexagon, octagon, etc.

The blanks 10; 110; 210; 310; 410; 510; 610; 710; 810 include at least a paperboard substrate. In an embodiment wherein each blank includes two or more substrates, the two or more substrates may optionally be laminated together before the carrier blank is die cut. The material of the paperboard substrate may be selected from any conventional paperboard, for example, ranging in weight upwardly from about 10 pt., preferably from about 16 pt. to about 28 pt. (0.028″/˜0.7 mm). Examples of such a substrate are: 27-point (pt.) SBS board (solid bleached sulphate paperboard coated on one side, trade name PrintKote®) or CNK® board (Coated Natural Kraft®—an unbleached kraft paperboard having a clay coating on one side, trade name CarrierKote™); 21-point (pt.) SBS board or CNK® board; and E or F flute corrugated fibreboard, manufactured by WestRock® Company. The paperboard substrate may be a bleached or unbleached board. The board may be coated on at least one side, optionally the side opposite the lamination, with a conventional coating selected for compatibility with the printing method and board composition.

It optionally includes 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 polymeric material and secured to the substrate. The tear resistant layer imparts toughness to the laminate structure. Suitable tear resistant materials may include, but not be limited to, tear resistant laminated sheet material, e.g., NATRALOCK®, which may include a layer of an n-axially oriented film, e.g., MYLAR®, which is a bi-axially oriented polyester, oriented nylon, cross-laminated polyolefin or high-density polyolefin. The orientation and cross-laminated structure of these materials contribute to the tear resistant characteristic. Also, tear resistance may be attributed to the chemical nature of the tear resistant material such as extruded metallocene-catalysed polyethylene (mPE).

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 level of tear resistance may also be used.

The adhesive layer may be formed of polyolefin material such as a low-density polyethylene (LDPE). The adhesive layer may be placed between the substrate and the tear resistant layer to secure the tear resistant layer to the substrate.
