• Such groupings may constitute a single pair or any other desired arrangement such as two rows of two packages each, two rows of three, four or five packages each or greater number of rows desired number of containers.
• such containers are relatively small and in order to provide for efficient handling during shipment and displays in retail outlets, it is desirable to stack the articles in tiers one above the other.
• each cup or pot is considered to represent a separate article.
• Some cups or pots are subdivided into separate sections (e.g. yoghurt pots in which the flavouring is in a separate section from the yoghurt).
• This invention relates particularly to a beam structure which interconnects a carton side or top wall with its base wall such that the longitudinal axis of the beam is inclined relative to the plane of the carton's top wall and engages with a recess between adjacent pots.
• Previous beams have required the carrier to be applied to an upright article grouping from below.

• the medial panel 48 is, in the preferred embodiment, hingedly connected to the shortest edge of bracket panels 34 and 36 by fold lines 46a and 46b.
• the carton of the present invention can be formed by a series of sequential folding and, optionally, gluing operations which can be performed in a known straight line machine so that the carton is riot required to be rotated or inverted to complete its construction.
• the folding process is not limited to that described below and can be altered according to particular manufacturing requirements.
• the articles are shown inverted for clarity only.
• the top wall panel 18 of carton blank 10 is brought into contact with the upper planar face of the articles A by relative vertical motion therebetween.
• the blank 10 is then part erected to provide a pair of oppositely disposed side walls by folding side wall panels 16, 20 inwardly about fold lines 24 and 26.
• the bracket panels 34, 36 are folded out of alignment with first base wall panel 12 and first side wall panel 16, such that first base wall panel 12 overlies the base of the articles A.
• the beam structure 14 is constructed by folding first and second support panels 38, 40 along common fold lines 50, 52 into an angular relationship with each other and with medial panel 48 ( Figure 4), such that medial panel 48 is uppermost.
• the folding of the first and second support panels 38, 40 simultaneously causes gusset panels 42a, 42b and 42c, 42d to be folded out of alignment with bracket panels 34, 36.
• the first and second support panels are automatically folded by virtue of the introduction of the beam structure into the gap between adjacent articles A.
• the width of the medial panel 48 is equal to or less than the spacing between adjacent pots but the overall unfolded width of the beam structure 14 is wider than the spacing between pots.
• the intrinsic resilience of the folded paperboard ensures that a snug fit is maintained between the support panels 38, 40 and the articles.
• Second base wall panel 22 is then folded over the base of articles A and is secured to first base wall panel 13 using glue, or other suitable means known in the art, such as mechanical interlocking means, for example thereby, forming a composite base wall.
• glue or other suitable means known in the art, such as mechanical interlocking means, for example thereby, forming a composite base wall.
• the carton is now folly erected, as shown in Figures 4, 5 and 6 with a beam of a substantially inverted "U" shaped cross section.
• bracket panels 34, 36 are not limited to being of trapezoidal shape.
• the support panels may be folded upwardly to form a beam of inverted structure.
• second base wall panel may be extended to cover the entire base, and may potentially be provided with a flap to be secured to first side wall panel 16.
• the beam support panels may flex, shown in Figure 5, so as to engage the articles to improve rigidity of the carton.
• the support panels function as engaging strips.
• the panels 38, 40 flex along the fold lines 44a, 50, 44d; and 44b, 52, 44c and these fold lines may be oriented so as to better confirm to the shape of the adjacent article.
• FIG. 7 a second embodiment of the invention as illustrated in Figures 7, 8 and 9, like parts have, where possible, been represented by like numerals with the addition of the pre-fix "1".
• the second embodiment is similar to the first embodiment, so only the differences are described in any greater detail.
• the blank 110 as illustrated in Figure 7, this embodiment differs from the first embodiment in that the first side wall panel has been omitted and the beam structure 114 is thus hingedly interconnected directly to top wall panel 118 along fold line 132. Additionally, the beam structure has been extended in length to compensate for the omission of the first side wall panel.
• support panels 138 and 140 are mutually hingedly connected along a common fold line 143 and further, that the gusset panels have been omitted such that support panels 138 and 140 are trapezoidal in shape and are directly hingedly interconnected to bracket panels 134 and 136 along fold lines 135, 139 and 137, 141 respectively.
• the carton of the second embodiment can be formed by a series of sequential folding and gluing operations which can be performed in a straight line machine so that the carton is not required to be rotated or inverted to complete its construction.
• first and second base wall panels 112 and 122 being secured together using glue or other suitable means known in the art to form a composite base wall as shown in Figure 8.

• the first and second support panels are automatically folded by virtue of the introduction of the beam structure 114 into the gap between adjacent articles A.
• the width of the support panels 138, 140 when in a co-planar state are wider than the space inbetween pots.
• the intrinsic resilience of the folded paperboard ensures that a snug fit is maintained between the support panels 138, 140 and the articles.
• the combination of a wraparound arrangement with a inclined beam interposed between articles substantially prevents the relative movement of the articles A and carton which may otherwise compromise the automated handling of the cartons and the stacking thereof.
• the beam arrangement may be used to replace end retention means which have hitherto been used to prevent relative horizontal movement between articles and carton, but which generally require an additional folding step to be carried out as part of the erection process.
• top As used herein, the terms “top”, “base”, “side”, “upper” and “lower” with respect to the panels of the carton are relative terms, and that the carton may be reoriented as necessary or as desired. Any reference to hinged connections should not be construed as necessarily referring to a single fold line only; indeed it is envisaged that a hinged connection can be formed from a score line, a frangible line or one, two or more fold lines without departing from the scope of invention.
• the present invention and its preferred embodiment relates to a beam structure in a wraparound carton which is shaped to provide satisfactory strength to hold at least one article securely but with a degree of flexibility so that the load transferred to the beam structure is absorbed by the carton.
• the shape of the blank minimises the amount of paperboard required.
• the carton can be applied to an array of articles by hand or automatic machinery.
