Definitions

  • This invention relates to a carton particularly of the end-loading type suitable for accommodating beverage containers such as bottles or cans.
  • Known cartons of similar construction take the form of a generally enclosed case having end closure panels which are adapted to bend so as to conform more closely to the shape of those containers which are in contact with the end closure panels thus tending to provide a tighter fitting package.
  • end closure panels which are adapted to bend so as to conform more closely to the shape of those containers which are in contact with the end closure panels thus tending to provide a tighter fitting package.
  • the extent of conformity of the end panels with respect to the packaged articles in known constructions is limited by the manner in which the end closure panels are scored with bend lines.
  • the present invention results from an appreciation that modification in the arrangement of such bend lines in the end closure panels results in a tighter fitting package.
  • One aspect of the invention provides a carton for accommodating beverage containers which carton comprises a bottom wall, a pair of side walls foldably joined respectively to the side edges of said bottom wall, a top wall foldably joined respectively to the upper edges of the side walls thereby providing a tubular structure wherein each end of said tubular structure has a pair of end flaps foldably joined respectively to said side walls which end flaps are foldable inwardly across said end, and an end closure panel foldably joined to said bottom wall and foldable upwardly into overlapping relationship with said end flaps, each of said end flaps being formed with a fold line adjacent the adjoining fold line between that end flap and the respective side wall, said fold lines together defining the side edges of a gusset panel having an initial lower portion with side edges which are divergent in the direction away from said bottom wall and an upper portion remote from said bottom wall having non-divergent side edges.
  • Figure 1 shows a blank 1 of paperboard or similar foldable sheet material for forming a carton 'C' for accommodating rows of bottles and comprises a bottom wall panel 2, a side wall panel 3, a top panel 4 and a further side wall panel 5.
  • the bottom wall panel 2 is foldably joined to one transverse edge of the side wall panel 3 along a transverse fold line 6.
  • the opposite transverse edge of side wall panel 3 is foldably joined to one transverse edge of top panel 4 along a transverse fold line 7 and the opposite transverse edge of top panel 4 is foldably joined to the further side wall panel 5 along a transverse fold line 8.
  • the free edge of bottom wall panel 2 includes a glue strip 9 foldably joined to the bottom'wall panel along transverse fold line 10.
  • the blank is symetrical about the longitudinal centre line "L-L” and for ease of understanding reference is made to those portions of the blank above the centre line "L-L” which depict the closure construction at one end of the carton 'C' as shown in Figure 2.
  • a bottom end closure panel 11 which tapers towards its free end is foldably joined to the bottom wall panel 2 along a longitudinal fold line 12 and a top end closure panel 13 is foldably joined to the top wall panel 4 along longitudinal fold line 14.
  • Integral end flap panels 15, 16 are foldably joined to the side walls 3, 5 along longitudinal fold lines 17, 18 respectively.
  • the end flap panels 15, 16 also are integral with and foldably joined to the top end closure panel 13 along the transverse fold lines 7, 8 respectively.
  • the top end panels 15, 16 are each formed with generally deltoid openings 19, 20 located in the case of panel 15 between transverse fold line 7 and an oblique fold line 21, and in the case of panel 16 between transverse fold line 8 and an oblique fold line 22.
  • the free end of the top end closure panel includes an integral tongue portion 23.
  • Each of the end flap panels 15, 16 are formed with further fold lines 24, 25 extending adjacent fold lines 17, 18 respectively and defining a pair of gusset panels 26, 27.
  • the fold line 17 comprises two angularly related portions 17',17" which meet at a transverse fold line 28 extending centrally across side wall panel 3.
  • fold line 24 comprises two angularly related portions 24', 24" which meet at the transverse fold line 28.
  • the fold lines 17, 24 together define the side edges of the gusset panel 26.
  • fold line 18 comprises two angularly related portions 18', 18" which meet at transverse fold line 28' extending centrally across side wall panel 5.
  • fold line 25 comprises two angularly related portions 25', 25" which meet at transverse fold line 28'.
  • the fold lines 18 and 25 together define the side edges of gusset panel 27.
  • the angular relationships of the fold lines defining gusset panels 26 and 27 are chosen such that the adjacent fold lines 17', 24' and 17" and 24" are divergent in a direction towards the transverse fold line 28 and the adjacent fold lines 18', 25' and 18", 25" are divergent towards the transverse fold line 28'.
  • first side wall panel 5 is bonded to the glue strip 9 thus bringing the blank to a sleeve like configuration ready for loading with bottles or other containers through the opposed open ends of the sleeve.
  • end flap panels 15, 16 are folded inwardly across the open end of the sleeve about their respective fold lines 17, 18 thus causing the top end closure panel 13 to initiate folding about fold line 14.
  • the top end closure panel will begin to fold owing to the folding movement of the integral tuck-in straps 29, 30 defined between fold lines 7, 21 and 8, 22 respectively and the panel 13 eventually will be brought into overlapping relationship with the upper portions of end flap panels 15, 16 and secured thereto.
  • bottom end closure panel 11 is caused to fold about fold line 12 and is brought into overlapping relationship with the lower portions of end flap panels 15, 16 and secured thereto.
  • the free end of bottom end closure panel 11 also is overlapped with and secured to the tongue 23 integral with top panel 13.
  • the carton panels are sized such that the overall carton width reduces towards its top end whereby the top panel 4 is narrower than bottom panel 2. Reduction in width is more prominent in the top section of the carton i.e. above the continuous central fold line constituted by transverse fold lines 28, 28'.
  • each gusset panel has side edges which are divergent in a direction away from bottom panel 2 up to the point of intersection with fold lines 28, 28' whereafter the gusset panel side edges are convergent towards the top panel 4.
  • the top panel 4 is formed with gripping apertures defined by push-in tabs 31, 32 and tearaway panels 33, 34 defined by perforate score lines formed in the top panel.
  • tear-away panels 33,34 are removed and discarded a central section of the top panel between tabs 31, 32 remains, thus providing a handle by which the carton can be grasped. This feature allows the carton to be used for returning empty beverage containers.
  • each of the gusset panels 26a, 27a are shortened relative to gusset panels 26, 27 so that the upper portions of those panels i.e. the small portions above the central transverse fold lines 28a, 28a' stop short of the carrier top panel 4.
  • each gusset panel has side edges which are divergent in a direction away from the bottom panel 2a up to the point of intersection with fold lines 28, 28' whereafter the side edges are convergent in a direction towards the corner apertures 19a, 20a respectively.
  • top panel 4a may be provided with the carrying and openings features previously described in relation to carton 'C'.
  • FIG. 5 of the drawings there is shown a blank lb of paperboard or similar foldable sheet material in which like parts of Figure 1 are designated like reference numerals but with the addition of suffix "b".
  • the layout of blank lb also is different to that of blanks 1 and la previously described in that a part of one side wall panel 5b is shown integral with top wall panel 4b and the remaining part of side wall panel 5b is shown integral with bottom wall panel 2b.
  • the effect of this layout is that both the side flap panels 15b, 16b depend from the bottom wall panel prior to glueing the blank into its sleeve-like configuration. This is necessary since the carton of this embodiment is not provided with a top wall end closure panel as in the previous embodiments.
  • the carton 'C2' is assembled in a similar fashion in that first the blank Ib is brought into a sleeve-like configuration by bonding the glue strip portion 9b of side wall panel 5b in overlapping relationship with the opposite part of side wall panel 5b. After the carton has been end-loaded with containers as previously referred to the carton ends are closed.
  • the end flap panels 15b, 16b are folded inwardly across the open end of the sleeve about their respective fold lines 17b, 18b.
  • This folding operation causes the bottom end closure panel llb to initiate folding about fold line 12b.
  • the bottom end closure panel will begin to fold owing to the folding movement of the integral tuck-in flaps 35, 36 provided between bottom end closure panel llb and each of end flap panels 15b and 16b respectively.
  • the tuck-in flap 35 will fold flat against the inside face of bottom end closure panel llb by folding about oblique fold lines 37, 38 and similarly the tuck-in flap 36 will fold flat against the inside face of bottom end closure panel 11b by folding about oblique fold lines 39, 40.
  • each gusset panel has side edges which are divergent in a direction away from the bottom panel 2b up to the point of intersection with central transverse fold lines 28b, 28b' whereafter the gusset panel side edges are convergent towards the top most edges of the respective end flap panels.
  • the top panel 4b is formed with handle apertures defined by pushing tabs 31b, 32b and tear-away panels 33b, 34b provided by perforate score lines formed in the top panel.
  • This construction permits the carton 'C2' to be used for returning empty beverage containers as mentioned previously.
  • the cartons 'C', and 'C2' adequate tightness of the carton end structure may be obtained if the upper portions of the gusset panels have side edges which are parallel to one another rather than convergent as described and shown.
  • the fold line portions 18b", and 25b" of gusset panel 27b may be formed parallel to one another and similarly fold line portion 17b" and 24b" of gusset panel 26b may be formed parallel to one another,
  • the convergent arrangement as described and shown is to be preferred.
