Abstract
There is provided a carton 11 having a pair of first side panels 18 and a pair of second side panels 19. The first side panels 18 are attached to a rear panel 17 and the second side panels 19 are attached to a front panel 15. Locking tabs 26 extend from the second side panels 19 and are received in arcuate slots provided by the first side panels 18. This enables the rear panel 17 and first side panels 18 to rotate thereby increasing the access area at the top of the carton. Top closure means 20, 22, 23 are also provided.
Description
- This invention relates to cartons, and more particularly but not exclusively to cartons which are made from paperboard. It is often a problem with cartons that it would be beneficial for the opening area of the carton to be larger than it is in order to improve access to the contents of the carton.
- According to the present invention there is provided a carton having a number of interconnected panels thereby to define an enclosed volume, one or more of said panels being movable relative to the other panels to increase said enclosed volume.
- In some arrangements, the panels include a base panel, front and rear panels connected to opposite edges of the base panel, top closure means, first side panels hingedly connected to the rear panel and second side panels hingedly connected to the front panel and interconnected with the respective first side panels so as to be movable relative thereto. Preferably the first side panels have one or more arcuate slots centered on the hinge connection between the rear panel and the base panel, inwardly projecting tabs being provided on the second side panels for interengagement with the slots to guide the movement of the rear and first side panels relative to the second side panels.
- Conveniently two spaced tabs and two spaced slots are provided on each side of the carton. In certain arrangements each tab has lateral projections which project radially beyond the arcuate side edges of its associated slot on the inside of the carton.
- Preferably the relative movement of the panels results in a substantial doubling of the length of the side edges at the top opening of the carton, when the carton is expanded.
- With preferred arrangements the top closure means comprises side flaps hingedly connected to respective second side panels and an overlying top panel hingedly connected to the rear panel, the top panel having a tuck flap remote from the rear panel for releasable retention between the front panel and the two side flaps.
- An embodiment of the invention will now be described in more detail, the description making reference to the accompanying drawings in which:
- Figure 1 is a view of a paperboard blank for producing a carton according to the present invention,
- Figure 2 shows a perspective view of the assembled carton in a closed condition,
- Figure 3 shows a perspective view from another angle of the carton of figure 2 with top closure means open, and
- Figure 4 shows a perspective view from yet another angle of the carton of figure 2 in an open and expanded condition.
- In the figures there is shown a paperboard blank 10 for producing a
carton 11 which in use may contain a number of articles (not shown) such as sweets. - The
carton 11 has abase panel 12 with two oppositely disposedlower side flaps 13 hingedly connected thereto. Also connected to thebase panel 12 by afold 14 is afront panel 15 and by afold 16 is arear panel 17. - The
rear panel 17 has at its side edges a pair offirst side panels 18 which in use lie inside ofsecond side panels 19 which are hingedly connected to the side edges of thefront panel 15. At the upper ends of thesecond side panels 19 areupper side flaps 20 which are hingedly connected to the respectivesecond side panels 19. Top closure means 21 are provided at the top of therear panel 17 and take the form of atop panel 22 and atuck flap 23. Such top closure means 21 andupper side flaps 20 are conventional in form and need no further description. - Each
first side panel 18 is provided with a pair of parallel sidedarcuate slots 24, each of which has as its centre of curvature in use thehinge 16 between therear panel 17 and thebase panel 12. Thetop edge 25 of eachrear panel 17 is also arcuate with a similar centre of curvature in use. - Each
second side panel 19 has a pair oflocking tabs 26 which are positioned for engagement with theslots 24. Eachtab 26 is in use folded inwardly aboutfolds 27 and through itsassociated slot 24. Each tab haslateral projections 28 which can be manipulated through itsassociated slot 24 so as to project radially beyond the arcuate side edges of theslot 24 on the inside of the carton. The marginal position of eachslot 24 is, therefore, disposed between theprojections 28 and thesecond side panel 19 when thecarton 11 is erected. Eachsecond side panel 19 also has alengthwise crease 29 which is generally parallel to and spaced from the free edge of the second side panel and thefolds 27. Thecrease 29 assists in keeping thesecond side panel 19 stiff when thetabs 26 are inserted into theslots 24 during erection of the carton. - In this way the tab/slot combinations act as a guide for movement of the
rear panel 17 and thefirst side panels 18 relative to thefront panel 15 and thesecond side panels 19. It will be seen from figure 4 that the open pack in its fully expanded condition effectively doubles the length of the top edge of the top opening thus increasing the access area at the top of the carton. The arcuate nature of thetop edge 25 of the first side panels maintains a smooth continuation of the top of thecarton 11. - The radial width of the slots is a matter of design choice but should be sufficient to enable the tabs to be manipulated therethrough but remain small enough to make it difficult for the articles in the carton to pass through.
- When access to the carton is no longer required, then the
rear panel 17 can be pushed inwardly to the position shown in figure 3. The top closure means 21 can then be closed and the tucking of thetuck flap 23 between thefront panel 15 and theupper side flaps 20 substantially prevents from therear panel 17 hinging about the base panel and into its expanded position. It will be appreciated that thesecond side panels 19 are external and thereby give the carton a conventional appearance prior to expansion. - It will be realised that the shape of the
carton 11 is simply an example and that the expansion arrangement can be applied to many different shapes of carton. Furthermore the number and form of the slots/tabs is for illustrative purposes and should not be regarded as limiting.
