Definitions

• This invention relates to a carton and blank design which incorporates provision for a handle and relates particularly but not exclusively to carton blank/handle constructions which are suitable for use with relatively heavy 5 contents such as packaged wine and to cartons constructed from same.
• the present invention provides a carton blank including along one edge a pair of inner closing flaps and a pair of outer covering flaps adapted to combine with 0 said closing flaps to provide an end to the formed carton, and a handle strip formed as an integral edge portion of a closing flap and adapted to extend across the formed carton, said strip being at least partly severable from the closing flap thereby to provide a handle for the formed carton.
• the invention provides a carton blank suitable for forming a carton of square or rectangular cross section there ⁇ from, wherein said carton is provided at one end with two pairs of opposed integral flaps, the first of said pairs of flaps being adapted to close off said carton end when folded there- 0 over and said second opposed pair of flaps forming a hand grip portion having a width substantially less than that of the carton end to which they are attached, when said second opposed pair of flaps is folded flat thereover and joined together.
• the second opposed pair of flaps are joined together using adhesive tape, a wire staple, a metal or plastic clip or a pre-glued strip which may be separated from one of the flaps of said first pair of flaps.
• the handle strip may be severable from the covering 0 flaps by any means such as score lines, slits or perforations.
• a length of adhesive tape may be applied over the strip, the ends of the tape overlapping and attaching them ⁇ selves to the carton sides.
• the strip can be used as a carry handle when it is severed from the flap. 5
• the present invention provides a formed carton including at one end a pair of inner closing flaps and a pair of outer covering flaps adhered to said closing flaps to provide an end to said carton, a handle strip formed as an integral edge portion of a closing flap and extending across the carton, and a pressure sensitive adhesive tape extending along said strip and onto the carton wall adjacent each end of said strips thereby to join said strip at its ends to the carton, said strip being at least partly severable from the closing flap thereby to provide a handle for the carton. It will be appreciated that in use the strip need only be severed from the closing flap to the extent necessary to allow for a persons fingers to pass beneath the strip.
• Fig. 1 shows an elevation of a partly erected carton constructed in accordance with the invention
• Figs. 2, 3, 4, 5 and 6 illustrate the various stages taken in folding the flaps and forming a handle.
• Fig. 7 is a perspective view of a partially erected carton constructed in accordance with the invention.
• Figs. 8 and 9 illustrate the steps taken for folding the flaps of the upper end of the carton of Fig. 7 to form a closed end with a carry handle;
• Figs. 10, 11 and 12 illustrate alternative methods of joining flaps to form a carry handle;
• Fig. 13 is a perspective view of an alternative form of partially erected carton constructed in accordance with the invention.
• Figs. 14 to 17 illustrate the steps taken for folding the flaps of the upper end of the carton of Fig. 13 to form a closed end with a carry handle.
• the carton 1 is of rectangular cross section and is constructed so that it can be readily erected from a flat blank by folding the blank along the fold lines 2 and joining opposed edges of the tubular partly formed carton by conventional means such as gluing.
• the flaps 7, 8, 9 and 10 are integral with the tubular body portion of the carton, the join between each carton and flap including the fold lines 11, which can be formed by any conventional means such as creasing, cutting or
• One of the flaps 7 has a line of weakening 12, which runs across the entire width of the flap.
• the line of weakening which may comprise for example, slits, perforations or long cuts, 12a, interrupted by perforations 12b, is provided to facilitate tearing of the strip portion 13 from the rest of the flap.
• the length of flap 7 is preferably chosen so that the flap extends most, but not all the way across the carton end when it is folded flat. Thus the strip portion will lie generally across the middle of the carton end.
• the steps a conventional box erecting machine may take to close the upper end of the carton involve bending back the flaps 7 and 9 in the manner illustrated in Fig. 2, so that they do not interfere with the folding of the flaps 8 and 10 as per Fig. 3.
• Adhesive such as the lines of hot melt adhesive 15, can then be applied to the folded flaps 8 and 10, prior to the flap 9 being folded thereover in the manner illustrated in Fig. 4.
• the final flap 7 is then folded down as per Fig. 5 and a length of adhesive tape 17 is applied over the strip portion 13 of the flap.
• the adhesive tape extends beyond the edges of the strip to be secured to the opposed side walls 17 and 18.
• the width of the strip may suitably be chosen so that the end of the remaining portion of flap 7 does not overlap the flap 9, but may be substantially in abutment with the leading edge thereof.
• the carton blank generally designated 1 may be constructed from any suitable sheet material such as solid fibreboard, corrugated board, E flute board or plastic for example.
• the sheet may be creased and cut using conventional processes and folded to form the tubular configuration of Fig. 7 with a square or rectangular cross-section, the various flaps protruding therefrom.
• the ends of the folded blank are overlapped and are held together by any appropriate means such as gluing or stapling.
• gluing or stapling As the bottom flaps of the carton are of conventional construction, these will not be discussed further.
• the upper flaps 2, 3, 4 and 5 all form an integral part of the blank from which the carton is constructed.
• OMPI for holding the two flaps 2 and 4 together when they are folded down over the carton end may be provided in the form of the tongue and slot 6 and 7 respectively.
• the tongue 6 fits into the slot 7 and the extensions 8 and 9 forming part of the flap 4 rest on the upper surface of flap 2.
• Opposed flaps 3 and 5 are then folded down over the flaps 2 and 4 which already close off the carton, and are joined together by any appropriate means such as adhesive taping, stapling or using a clip as shown in Figs. 10, 11 and 12 respectively.
• the opposed flaps 3 and 5 are constructed in such a way that a relatively narrow elongate grip portion 10 is formed in the region of the centre of the carton end when the two are joined together.
• the ends of the flaps 3 and 5 abut each other when they are folded down.
• flaps which overlap to achieve the same result.
• a carton blank 30 has been formed into a hollow tubular member with integral upper flap members 31, 32, 33 and 34. Flap member 32 is made longer than its opposed flap member
• Flap 31 is formed with a line of perforations 35 or the equivalent which permit the elongate strip 36 to be separated therefrom.
• the strip readily separates from the flap 31 because of the perforations 35 to form the slightly raised hand grip portions
