  • minor flap 48 is hingedly connected to top wall panel 12 along fold line 50 and flap 42 is hingedly connected to base wall panel 16 along fold line 44 and the minor flaps 42 and 48 are separated from the first end wall panel 34 along cut lines defining edges 46 and 52.
  • the minor flaps 42 and 48 are provided with a cut away portion.
  • the cut away portions are provided by making the minor flaps 42 and 48 generally triangular in shape; although it is envisaged that other shapes can be used without departing from the scope of invention. More preferably, there comprises an end edge 43 provided in the minor flap 42 and end edge 45 provided in the minor flap 48.
  • first end wall panel 54 hingedly connected to side wall panel 14 along fold line 56 and a second end wall panel 58 hingedly connected to side wall panel 18 along fold line 60.
  • minor flap 62 which is hingedly connected to base wall panel 16 along fold line 64.
  • a first side edge of the minor flap 62 is defined by cut line 66 and an opposed cut edge 67 defining along the opposing side edge of the minor flap.
  • access structure 70 that is provided in the corner between the top wall panel 12 and the end wall structure formed from end wall panels 54 and 58.
  • the access structure is not limited to this position or arrangement within the carton and can be formed along one of the side walls or between the base and the opposing end of the structure, without departing from the scope of invention.
  • the access structure 70 is provided with a first access opening 72 formed, in this embodiment, by a recess formed in first end wall panel 54.
  • Slidable panel 74 is hingedly connected to intermediate panel 76 along fold line 78 and intermediate panel 76 is hingedly connected to the top wall panel 12 along fold line 80.
  • a tab 82 struck from intermediate panel 76 by cut line 81.
  • Tab 81 is provided to facilitate manipulation ofthc slidable panel 74 in a set up carton.
  • the slidable panel 74 is provided with a second access opening or cutout, 84. It is envisaged that the cut-out 84 and recess 72 can be increased or decreased in size according to the product contained within the carton and according to the desired flow rate.
  • the tamperproof arrangement 71 comprises a tamperproof member 90, hingedly connected to an intermediate panel 86 along fold line 92. Intermediate panel 86 is hingcdly connected to end wall panel 58 along fold line 88. Optionally fold line 88 is replaced with a frangible line.
  • a tab 94 hingedly connected to tamperproof member 90 along fold line 95.
  • the tamperproof member 90 is also provided with a glue patch 96 frangibly connected thereto along frangible line 98.
  • folding and gluing operations are required and will be described further with reference to Figures 2 to 12 of the drawings.
  • the folding and gluing operations can be performed in one or more straight-line machines, so that the carton is not required to be rotated or inverted to complete its construction.
  • the folding process is not limited to that described below and can be altered according to particular manufacturing requirements.
  • the carton is constructed by securing the ends of the blank to form a flat collapsed carton.
  • the inner top wall panel 2U and securing flap 30 are folded inwardly along fold line 28, as shown in Figures 2 and 3.
  • glue (marked with cross-batching), or other suitable known securing means, is provided on the securing flap 30 and inner side wall panel 20.
  • the carton is in a flat collapsed form as shown in Figure 4, ready to be supplied to an end user, for loading or to move on to the next stage of the construction and erecting process.
  • the tamper proof member 90 is illustrated in Figure 4 as protruding from the carton, although in other embodiments the tamper proof member 90 is folded inwardly along fold lime 92 when top wall panel 20 is folded inwardly.
  • tamper proof member 90 is held within the carton, until it is required to be set up.
  • this reduces the risk of damage to the tamper proof member 90.
  • first end wall structure 33 and Figures 5, 6 and 7. In order to construct the ends of the carton, reference is made to the first end wall structure 33 and Figures 5, 6 and 7.
  • inner end wall panel 38 is folded inwardly along fold line 40, thereafter minor flaps 42 and 48 are folded inwardly to come into face contacting arrangement with the inner end wall panel 38. It will be seen that inner end wall panel 38 covers the entire width between the opposed side wall panels.
  • a line of glue is applied across the length of end wall panel 34 which is then folded inwardly over minor flaps 42 and 48 and inner end wall panel 38 to hold the aforementioned panels firmly in place.
  • this avoids powder loss by increasing the area of the overlap between the inner and outer end wall panels 34 and 38, because the minor flaps 42 and 48 have a cut away portion.
  • glue strips are provided laterally whereby each glue strip secures the inner and outer end walls 38, 34 and one of the minor flaps 42; 48.
  • the opposing end wall structure is formed by the inner end wall panel 54 when it is folded inwardly along fold line 56 and the minor flap 62 is folded into overlapping arrangement with inner end wall panel 54 along fold line 64.
  • glue is applied to outer end wall panel 54 (marked with cross hatch in Figure 11), which, in this embodiment, comprises two strips of glue and is folded inwardly to secure the inner end wall panel 54, the minor flap 62 and the outer end wall panel 58 together.
  • the tamper proof member (or stopper flap) 90 is folded inwardly along fold line 92 and glue patch 96 is secured to top wall panel 12 as shown in Figures 11 and 12.
  • glue patch 96 is secured to top wall panel 12 as shown in Figures 11 and 12.
  • the user In order to gain access to the interior of the carton, the user lifts the lower part of tab 94 and folds it outwardly along fold line 95 as shown in Figure 13.
  • the glue patch 96 becomes detached from tab 94 and the tamper proof member 90 is folded back along fold line 92 as shown in Figure 14; and may optionally be removed by tearing along nick points defined in frangible line 88 to reveal the access structure 70, shown in Figure 15.
  • the slidable panel 74 is moved in an outward direction X, shown in Figure 16, by pivoting it about fold line 80 so that intermediate panel 76 is swingable and moved about fold lines 78 and 80.
  • This action brings the second opening 84 into a partial overlapping arrangement with the first opening (or recess) 72.
  • By changing the amount of overlap it will increase or decrease the size of the distribution hole, so that the amount of product to be discharged from the carton can be varied according to the size of the distribution hole.
  • a further advantage of the arrangement described above is that a pourer is provided through these apertures, with a tamperproof structure.
  • the shape of the inner and outer end flaps is not limited to that described above and can be altered according to the particular size and shape of carton to be manufactured.
  • the present invention and its preferred embodiment relates to an arrangement for providing a reclosable access structure in a fully enclosed carton.
  • the invention can be applied to a variety of cartons and is not limited to those of the fully enclosed type hereinbefore described and could be used for numerous applications.
  • hinged connection should not be construed as necessarily referring to a single fold line only: indeed it is envisaged that hinged connection can be formed from one or more of one of the following, a score line, a frangible line or a fold line, without departing from the scope of invention.
  • the size and shape of the panels and apertures may be adjusted to accommodate articles of differing size or shape, alternative top and base closure structures may be used.
  • the carton may accommodate more than one article in different arrays.
