Abstract

A blank for forming a carton with a tuck-in end comprises a tuck-in flap (42) and at least one end flap (30, 32). A side flap (64, 66) extends from the tuck in flap (42) and is connected to the tuck-in flap (42) through a fold line (68, 70). When the carton is erected, the side flap (64, 66) can be folded under the tuck-in flap (42) so that the edge of the tuck-in flap presents a fold line rather than a cut edge. In the same way, a body panel (14) opposite the body panel (18) to which the tuck-in flap (42) is connected may also be connected through a fold line (52) to a further flap (60) which can be folded into the carton so that the upper edge of that body panel (14) presents a fold line (62) rather than a cut edge. <IMAGE>

Description

A CARTON AND A BLANK The invention relates to a carton and a blank.

Many cartons are known which are rectangular and have a tuck-in end. The tuck-in end comprises a tuck-in flap comprising a rectangular top panei connected through a fold line to a small flap which is tucked in and two rectangular or trapezoidal flaps connected to the top edges of the body panels on either side of the body panel to which the top panel is connected. The blank for forming the carton may be printed. When the carton is erected and the tuck-in end closed, certain cut edges of the carton will be visible, for example the top edge of the body panel opposite the body pane; to which the main top panel is connected and the sid edges of the main top panel.These cut edges m detract from the overall appearance of the carton, particularly where the carton has been printed in one colour and the cut edges break the continuit of the colour over the carton.

According to one aspect of the invention there is provided a carton formed from a blank, the carton including a tuck-in end which includes a tuck-in fiap connected to a body panel of the carton, the car-on also including an opposite flap connected through a fold line to a body panel of the carton opposite the body panel to which the tuck-in flap is connected.

In this way, the cut line which would have been visible at the top of the bod panel is replaced by a fold line.

Preferably, the opposite flap is arranged to be folded inside the carton. In this way a neat folded edge is presented at the top of the body panel. Preferably, the opposite flap is secured to the inner face of the opposite body panel of the carton. Preferably, the opposite flap extends along the entire end edge of the opposite body panel of the carton.

The tuck-in flap may also include a side flap connected through a fold line to a sid edge therecf.

According to another aspect of the invention there is provided a carton formed from a blank, the carton including a tuck-in end comprising a tuck-in flap, the tuck-in flap including a side rap connected through a fold line to at least one side edge ther-toz.

In this way, the cut edge at each side of the tuck-in flap on the prior carton is replaced by a fold line.

Preferably, a side flap is connected to each side edge.

The or each side flap is preferably arranged to be folded under the tuck-in flap and preferably is secured to the inner face of the tuck-in flap. The or each side flap preferably extends along an entire side edge of the tuck-in flap.

According to a further aspect of the invention there is provided a blank for forming a carton according te either of the previous aspects of the invention.

According to another aspect of the invention there is provided a blank for forming a carton with a tuck-in end, the blank including a plurality of body panels and the tuck-in end comprising a tur-in flap and at least one end flap, the tuck-in -'ap ending from one body panel and the or one end ap extending from a second body panel next to the first body panel wherein a side flap extends from the tuck-in flap on the same side thereof as a second body panel and is connected to the tuck-in flap through a fold line.

Preferably, the side flap extends along the entire side edge of the tuck-in flap and Preferably also the said end flap extends along the tire end edge of the second body panel to which it is attached.

Preferably, the side flap and the said end flap are separated by a cut line. The cut line may extend to the edge of the body panels. The cut line may t any suitable form and in one embodiment is straight.

In that case, the cut line preferably extends at an angle so as to substantially bisect the angle formed between the edge of the tuck-in flap to which the side flap is connected and the edge of the body pane to which said end flap is connected.

An embodiment of the invention Aill now be described by way of example and with reference to the accompanying drawings.

Fig. 1 is a plan view of a prior blank; Fig. 2 is a perspective vet a a arson from the prior blank of Fig. 1; Fig. 3 is a blank according to the invention in a first embodiment, and, Fig. 4 is a perspective view of a carton formed from the blank of Fig. 3.

The prior blank of Fig. 1 comprises four rectangular body panels 12,14,16,18 serially connected through fold lines 20,22,24. The body panels are alternately relatively wide and slim. The slimmer body panels 12, 16 are each connected at their upper edges through fold lines 26,28 to end flaps 30,32. The end wider body panel 18 is connected at its outer edge through a fold line 34 to a narrow glue flap 36. The end wider body panel 18 is connected at its upper edge though a fold line 38 to a tuck-in flap 40 which comprises a rectangular top panel 42 and a flap 44 connected thereto through a fold line 46. The lower edges of the body panels 12,14,16,18 are connected to flaps 48,50,52,54 to form a crash-lock base. The crashlock base flaps 48 to 54 are conventional and will net be described further.

Fig. 2 shows a rectangular carton formed from the blank of Fig. 1.

The main body panels 12,14,16,18 have ben folded through 90" about the fold lines 2S,22,24 to form a rectangular tube and secured by giuing of the giue flap 36 to the inner face of the end slimmer body panel 12. The crash lock base flaps 48,50,52,54 have been secured and crash locked in the known manner.

The end flaps 30,32 have been folded through 90 across the tube opening about fold lines 26,28 and the top panel 42 has been folded across the top of the tube opening and the end flaps 30,3 about fold line 38.

It will be seen that, when the carton is closed, the upper edge 56 of the wider body panel 14 is visible together with the side edges 58 of the top panel 42.

These edges are cut edges of the blank and therefore will contrast against the rest of the carton which may be printed.

Fig. 3 shows a blank according to the invention in one embodiment. The blank has features in common with the prior blank of Fig. 1 and only the diferences from the blank of Fig. 1 will be described with the same reference numerals being used for common features.

The blank of Fig. 3 includes an opposite flap 60 which extends from the top edge of the wider main panel 14 through a fold line 62. The opposite flap 6a is about half the length of the top panel 42 and extends over the entire top edge of the wider main body panel 14.

To each side edge of the top panel 42 is connected a side flap 64, 66 through a fold line .5. The upper edge of each side flap 64,66 extends co-linearly with the fold line 46 which is parallel to the fold lines 26,28,38,62. The edge of the side flap 61,6 nen turns downwards through 900 to extend parallel with the fold lines 68,70 over about half the length of the fold lines 68,70 and then angles inwardly by 45 to meet the junction between the fold lines 6,70 and 28,38 and 24,34. In order to accommodate the side flap 68, the end flap 32 is slanted on the side adjacent the side flap 68.

In this way, the cut edges 58,56 of the prior carton are replaced by fold lines 62,68,70.

Fig. 4 shows the carton erected from the blank of Fig.

3. The opposite flap 60 has been folded about the fold line 62 into the tube formed by the main body panels 12,14,16,18 and secured to the inner ace of the main body panel 14 to which it is connected.

Similarly, the side flaps 64,óó have been ~~;den inwards about the fold lines 68,70 to lie under the top panel 42 and they hae been secured to the inner face of the top panel 42.

It will be seen that, when the carton is ciosed, no cut edges are visible at the tuck-in end. The top panel terminates in fold lines 38,68j46,t0 and the main body panels 12,14,16,18 terminate upwardLy at fold lines 26,62,28,38. As each fold line extends over the entire length of each edge, no cut edges are present.
