The carton has apertures in its side walls (21, 22) for receiving the heel portions of the cans (12) and gusset portions between each side wall (21, 22) and the top panel (13). When assembled, one panel (35) of each gusset portion extends partially across the open end area of the carton to prevent dislodgement of the tops of the cans (12).

Description

w o 93/02943 . 2 0 919 8 8 PCT/GB92/01471 Carton for a plural1ty of art~cles and blank therefor.
~ "
This invention relates to cartons and blanks therefor.
Various cardboard sleeves for multipacks are ' 5 known, but generally have apertures at the junction of the side and top panels for receiving the top edges of the articles. With certain articles, especially cans, the necessary aperture is located very close .o the end edge of the sleeve and thus render the remaining - 10 strip of card vulnerable to tearing whenever the pack is handled. Tearing of course seriously affects the usefulness of the sleeve, but compactness of carton is ;~ essential not only from an aesthetic point of ~iew but ' also from a business point of view. Clearly it is ; 15 desirable to use as little cardboard as possible whilst retaining structural integrity and also bulkier '~ cartons occupy more space and increase transport '~:
~, costs.
According to a first aspect of .he present ; 20 invention there is provided a carton for receiving a I plurality ~of articles, which carton comprises a top portion, a bottom portion, two side portions, the side and/or bottom portions being provided with formations -- for engaging the heel portions of at least some of ` 25 said articles, and gusset portions provided between ~ - the side portions and the top portion so as to extend ; across at least part of each end area of the carton.
- Preferably two gusset portions are provided at ;each end of the carton between each side portion and 3- each~ top portion. The formations for engaging -the heel portions are in the form of apertures in each of . which is received and retained a heel portion.
~ !.J ;.; In a preferred emboaimen. each gusset portion ;. ~ ---- comprises two panels, the first of which is hingedly - - ~ .

connected to the top portion and the second of which ' is hingedly connected to the associated side portion, :
both panels being hingedly connected together such ' that one of said panels is bent towards its associated portion to allow the other panel to extend across the open end area of the carton.
It is a preferred feature that no further hinges are provided in said other panel of each gusset ~:portion. Also said one panel of each gusset portion is held against its associated top or preferably side ~ portion by one of said articles.
'1:`' Preferably, the top portion is hingedly connected alona opposite side edges to the side ':~` portions and each side portion is hingedly connec~ed ' to a bottom panel, the two bottom panels being secured together to constitute said bottom portion.
In one arrangement the two bottom panels are formed with interengaging formations to effect their securing together. Alternatively, the two bottom panels could be adhesively secured together.
~''- 'Conveniently the carton is adapted to receive ~' two 'rows of articles so that two articles-face each .~ open end and the articles are retained in-the carton '' ' by the'gussetted portions and the heel engaging ; ~' formations, one of which is provided for each article.
25Ideally, the cartons are formed from cardboard '`~ ' and the'hinged'connéctions 'may be constituted by fold ~' lines, `scor'e lines or skip/score lines. ~
' ` '''' According` to"''a second aspect- of the present invention,' there'is'provided à blank for p'roducing a ~'. 3carton for receiving a `plurality of articlès, which blànk provides paneis for constituting a top portion, . two~'sidé'portions''ànd-a bottom po'rtion, which panels '`'' aré''hinqedly connected togèther,~ said blank providing ''at least' one'gusset portion between a side~portion and ~'`';~ `35 the top portion at each end thereof, each gusset ~;:

20919~8 portion being constituted by two panels, the first of '' which is hingedly connected to the associated side portion and the second of which is hingedly connected to the top portion, both panels of the gusset portion being hingedly connected together.
Embodiments of the invention will now be ' -' described in more detail. The description makes ,~ reference to the accompanying diagrammatic drawings in ~ which:
,,; 10 Figure 1 shows a blank according to the present invention, ~', Figure 2 is a perspective view of the blank of ,~ Figure 1 being assembled into a carton, Figure 3 is a perspective view of a carton ', 15 according to the present invention made from the blank shown in Figure 1, and ~, Figure 4 is an end view of the carton shown in Figure 3. , ' Figure 1 shows a blank 10 for forming a carton 11, as shown in figures 2 to 4, around a plurality of articles which in-this case is six cans 12 for '' beverages arranged in two rows of three. The carton ' 11 has a top portion 13 formed with two finger holes ''"~ 14 for facilitating the carrying of'the carton.
' 25 Hingedly connected to each side edge of the' top ' portion along fold lines 15, 16 are upper side panels 17,--18 which are adapted 'to conform to the~bevelled , ' `uppër`surfaces of-thé cans 12.'~Hingedly connected to '~ '`each side 'of the upper side panels 17, 18 along fold '' 3 lin'és i9, 20 are main side--panels 21, 22. Hingedly ' ' '' 'connected to the lower èdges of the side panels 21, 22 -` ' aiong-fold lines 23,- 24-are lower'side panels'25, 26 wh`ich''in turn are connected~along fold lines 27, 28 to ' bottom panels 29, 30.

., with apertures 31 and formations 32 for engaging and -~ retaining heel portions of the cans 12. As can be seen in figure 4, the heel of the can protrudes to .~. some extent through the aperture 31 and this serves to .,.-' prevent to a great extent transverse movement of the,`. 5 can 12 within the carton 11.
. .
The bottom panels 29, 30 are provided with ''. various formations 33 which are arranged so as to .' interlock and interengage so as to close the blank 10 to form the sleeve-like carton 11.
10The blank 10 is also formed with gusset , portions 34 which interconnect each side panel 21, 22 ~'' with the top portion 13. Each gusset portion 34 has a '~ first panel 35 hingedly connected to the top portion ;, 13 and a second panel 36 hingedly connected to the ~` 15side panel 21, 22 along the fold line 37. The first ~' - and second panels 35, 36 are also hingedly connected .,.~; together along fold line 38. The upper side panel 17, 18 is bypassed by the provision of a hole 39.
~-~ When forming the carton 11 around the cans 12, '' 20 the top portion is placed across the tops of the cans , and .the side panels and bottom panels are folded '. around the cans 12. During the folding the second '~ panels ,6 of the gusset portions 34 are tucked in ~. behind their associated side panels 21, 22 and the .:.': 25 bottom panels 29, 30 are.connected together. These . ~ second panels 36 and the lower part of the first .. : ,portions 35 are,.in the finished carton 11, sandwiched ,:', .~in~position between the cans~12 and the side panels '',. ~ ,- -21, 22-and cannot readily~ be pulled out., In the `~; 30.~finished carton ll,the.first.panels 35 of the gusset , oortlons 34 partially block the open end~areas of the ~': . .carton,and thereby prevent the tops of the ,cans from , ., , ~;. being.removed from the carton. This_is clearly shown . in figure 4.

~It will be appreciated that articles other '~than beverage cans can be used in the above described carton. For example, the carton could be adapted for use with bottles. Also different types of can would require slightly modified panel arrangements. For example, if the cans do not have an upper bevelled surface then the upper side panels 17, 18 may be -omitted to leave the main side panels 21, 22 hingedly connected directly to the top portion 13. In addition it will be appreciated that other bottom panel securing techniques are envisaged, for example different formations 33 may be used or the two panels may simply be secured with adhesive. Also the connection between the ends of the blank has been shown as being in the bottom portion, but it will be ,appreciated that it could be located in a side or the top portion if required. Further modifications may include further fold lines in the first gusset portion if desired or in any other panel so as to accommodate features of the articles being contained.
The carton is ideally suited to manufacture ::-'~ from paperboard but other semi-rigid or rigid sheets ~- could be used. Also fold lines could also encompass - 25 score lLnes or àny combinatlon of fold lines and score ~' lines. ~
;~The above described typë of carton provides a secure package for a plurality of articles and does not rely on apertures for retaining the tops of the articles. The weak spots between the endmost top apertures and the end edge of known cartons are therefore eliminated without adding bulk to the carton.
