Abstract
Description
- This invention relates to a carton accommodating a plurality of articles which includes a keel construction upstanding internally of the carton to provide both separating and retaining means for the packaged articles. Typically the articles comprise tubs, pots or jars containing foodstuff. A carton according to the preamble or
claim 1 is known from FR-A-2647421. - The invention provides a carton accommodating a plurality of articles of the type having an internal keel structure which protrudes inwardly of the carton to form a separator to space apart adjacent articles on either side of the keel structure, said keel structure comprising two portions arranged in spaced relationship with respect to each other, each of which portions is provided by at least one side panel, the carton being characterised in that said keel portions comprise complementary securing portions which cooperate to form a bridge element and thereby set up the said keel structure.
- According to a feature of the invention, each keel portion may comprise a side panel which is hingably attached to a panel of said carton and a top panel which is hingably attached to the keel side panel and which provides one of said securing portions.
- According to another feature of the invention, each keel securing portion may comprise a tab which abuts the other keel securing portion in face contacting relationship. In constructions where this feature is adopted, the keel securing portions may comprise complementary tabs which can be glued together to secure the keel in an operative set-up position.
- According to yet another feature of the invention one of the keel securing portions may comprise an aperture and the other of the keel securing portions may comprise a tab which passes through the aperture when the keel is in a set-up operative position.
- According to a further feature of the invention, said keel portions may be struck from a single panel of the carton. In constructions in which the keel portions are struck from a single panel, the single panel may be a base panel of the carton.
- According to a still further feature of the invention, a plurality of keels may be provided in one or more rows in which each keel acts to separate two adjacent articles.
- Various embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which:-

- FIGURE 15 is a perspective view, similar to Figure 8, showing the modified keel of Figure 14 in a set-up condition.
- Referring first to Figures 1 to 4 there is shown a carton 'P' of the wraparound type formed from a blank 10 of paperboard or other suitable foldable sheet material. The carton accommodates an array of four articles A disposed in two rows of two. Carton blank 10 comprises
top panel 12 andside panels top panel 12 alongtransverse fold lines base panels side wall panels transverse fold lines panel sections side walls base panels transverse fold lines top panel portions top panel portion 32 is hingably connected tokeel side panel 30 along interruptedfold line 42 whilst keeltop panel portion 36 is hingably connected to keelside wall panel 34 along interruptedfold line 44. Keeltop panel 32 comprises atab receiving recess 48 whilsttop panel 36 compriseskeel locking tab 50. Formation of the keel into a set-up condition is shown in Figures 3 and 4.Tab 50 is passed intorecess 48 and caused to underlietop panel 32. The marginal portions of keeltop panel portion 32adjacent recess 48 are caused to underlie keeltop panel portion 36 thus creating an interlocked top panel portion to keel K. Keel K is further stabilised by the interlocking of the base panels by means oflocking tab 52 which is rotated upwardly abouthinge 54 and caused to pass through acomplementary locking aperture 56 defined byflap 58 and struck fromtab 50 formed inbase panel portion 24. This embodiment requires no gluing of the keel and is found to be more economical in its use of carton material, such as paperboard, than known carton keel constructions. - Referring now to Figures 5 to 9 there is shown another carton Pa embodying the invention in which like parts of the previous embodiment are designated like reference numerals with the addition of suffix 'a'. The carton accommodates a group of four cartons 'Ca'. The carton comprises a wraparound paperboard blank 10a having
top panel portions side panels marginal top panel 12a′ to the underside oftop panel portion 12a.Top panel portion 12a is hinged toside panel 16a along interruptedtransverse fold line 20a andtop panel portion 12a′ is hinged toside wall panel 14a along interruptedtransverse fold line 18a. Two individual keel structure parts Ka and Ka′ are formed by striking a series of keel elements from asingle base panel 22a.Base panel 22a is hinged toside panel 14a alongtransverse fold line 26a and toside panel 16a alongtransverse fold line 28a. The keel part Ka comprisesside panel elements top panel element 32a. To form the keel part, theside panel elements fold lines top panel 32a is folded aboutfold line 42a.Keel locking tongue 50a is inserted into a complementarykeel locking aperture 48a inside wall 34a.Tongue 50a can then be rotated upwardly abouthinge line 44a in order thatside panel 34a andtongue 50a are generally co-planar and can lie smoothly against the side of an article Ca. Keel part Ka¹ is formed in a similar manner. Thus, an interrupted keel is formed which requires no gluing to retain its set-up formation. The keel elements are formed from material struck from thebase panel 22a and do not require additional material. - Figure 9 shows a similar keel part Kb to that shown in Figure 8 but in which keel part Kb is modified by removing
tongue 50a andaperture 48a and substituting therefor hinge 42b inkeel side wall 30b thereby creating two approximatelysymmetrical side walls 30b and 34b.Top flaps - Referring now to Figures 10 and 11 there is shown yet another embodiment of the invention in which carton Pc is formed from a wraparound paperboard blank 10c for packaging a group of articles Cc such as tubs of yoghurt.

Keel part Kd comprises
side walls blank base panel 22d and hinged upwardly aboutfold lines - Keel part Kd further comprises
top panel portions fold line Keel top panel 32d comprises securing flaps f₁ and f₂ and receiving aperture Rd.Top panel 36d comprises securing portions S₁, S₂ and securingtongue 50d.Tongue 50d is struck fromtop panel 36d on its marginal edges byslots 50d′.Keel top panels tongue 50d passes beneathpanel 36d whilst portions S₁, S₂ pass above it. Flaps f₁ and f₂ are passed beneathtop panel 32d and receiving aperture Rd moves into engagement withslots 50d′ thus securing the keel part Kd in an upright position. - Referring now to Figures 14 and 15 there is shown a still further embodiment of a keel part Ke which comprises
side panel base panel 22e and are foldably connected thereto alonghinge lines side wall panels hinges top panel portions Top panel portion 32e comprises article receiving recess, flap receiving recess Re and marginal flaps f1e and f2e.Top panel 32e is hingably connected toside panel 30e alonghinge line 42e which extends from each side of theflap portion 64e cut fromside panel 30e in order to formarticle receiving recess 65e. Similarlytop panel 36e is hingably connected toside panel 34e along hinge line 44e wherepanel 36e comprisesflap portion 67e defining recess 66e.Top panel 36e further comprises central tab 50e and central tab marginal slots 50e′ and marginal tabs 51e and 52e.Top panels tab 50c lies beneathpanel 32e and the edge of recess Re is brought into engagement with slots 50e′ whilst tabs 51e and 52e lie above flaps f1e and f2e.
