minor flaps minor flaps end edge 43 provided in theminor flap 42 andend edge 45 provided in theminor flap 48. - Along the opposing end wall there is provided a first
end wall panel 54 hingedly connected toside wall panel 14 alongfold line 56 and a secondend wall panel 58 hingedly connected toside wall panel 18 alongfold line 60. There further comprises aminor flap 62, which is hingedly connected tobase wall panel 16 alongfold line 64. A first side edge of theminor flap 62 is defined bycut line 66 and anopposed cut edge 67 defining along the opposing side edge of the minor flap. - There further comprises an
access structure 70 that is provided in the corner between thetop wall panel 12 and the end wall structure formed fromend wall panels - The
access structure 70 is provided with a first access opening 72 formed, in this embodiment, by a recess formed in firstend wall panel 54. There further comprises aslidable panel 74, which is hingedly connected totop wall panel 12 by means ofintermediate panel 76.Slidable panel 74 is hingedly connected tointermediate panel 76 alongfold line 78 andintermediate panel 76 is hingedly connected to thetop wall panel 12 alongfold line 80. Preferably, there is provided atab 82 struck fromintermediate panel 76 bycut line 81.Tab 81 is provided to facilitate manipulation of theslidable 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 andrecess 72 can be increased or decreased in size according to the product contained within the carton and according to the desired flow rate. - In one class of embodiments, there further comprises a
tamperproof arrangement 71, which is provided adjacent the secondend wall panel 58 and is hingedly connected thereto alongfold line 88. Thus, thetamperproof arrangement 71 comprises atamperproof member 90, hingedly connected to anintermediate panel 86 alongfold line 92.Intermediate panel 86 is hingedly connected toend wall panel 58 alongfold line 88. Optionallyfold line 88 is replaced with a frangible line. There further comprises atab 94 hingedly connected totamperproof member 90 alongfold line 95. Thetamperproof member 90 is also provided with aglue patch 96 frangibly connected thereto alongfrangible line 98. - In order to form the completed carrier in flat collapsed condition from the blank, a series of sequential 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.
- Referring to Figures 2, 3 and 4, the carton is constructed by securing the ends of the blank to form a flat collapsed carton. Thus, the inner
top wall panel 20 and securingflap 30 are folded inwardly alongfold line 28, as shown in Figures 2 and 3. Preferably glue (marked with cross-hatching), or other suitable known securing means, is provided on the securingflap 30 and innerside wall panel 20. By foldingside wall panel 14 and outertop wall panel 12 inwardly alongcentral fold line 24, these panels are brought into face contacting arrangement with securingflap 30 and innertop wall panel 20 and are secured thereto by glue or other suitable means known in the art. Thus 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. Thetamper proof member 90 is illustrated in Figure 4 as protruding from the carton, although in other embodiments the tamperproof member 90 is folded inwardly alongfold lime 92 whentop wall panel 20 is folded inwardly. Thus, tamperproof member 90 is held within the carton, until it is required to be set up. Advantageously, this reduces the risk of damage to thetamper proof member 90. - 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. Thus the innerend wall panel 38 is folded inwardly alongfold line 40, thereafterminor flaps end wall panel 38. It will be seen that innerend 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 overminor flaps end wall panel 38 to hold the aforementioned panels firmly in place. Beneficially, this avoids powder loss by increasing the area of the overlap between the inner and outerend wall panels minor flaps - In another class of embodiments, there further comprises two or more longitudinally extending glue strips shown in Figure 6, to improve the securing arrangement proximate each side of the carton. In a yet further embodiment of the invention glue strips are provided laterally whereby each glue strip secures the inner and
outer end walls minor flaps 42; 48. - Likewise, the opposing end wall structure is formed by the inner
end wall panel 54 when it is folded inwardly alongfold line 56 and theminor flap 62 is folded into overlapping arrangement with innerend wall panel 54 alongfold line 64. Thereafter, 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 innerend wall panel 54, theminor flap 62 and the outerend wall panel 58 together. - In order to construct the
access structure 70, reference is made to Figures 8 to 11, wherebyslidable panel 74 is first folded inwardly alongfold line 78, as shown in Figure 9. Thereafter, theend wall panel 54 comprising therecess 72 is folded inwardly alongfold line 56 so that therecess 72 overlaps theslidable panel 74, shown in Figure 10. Thereafter, the end wall structure is formed whereby theminor flap 62 is placed in overlapping arrangement with innerend wall panel 54. Glue is applied to outerend wall panel 58 and is then folded inwardly alongfold line 60 so as to secure the innerend wall panel 54, theminor flap 62 and the outerend wall panel 58 together in overlapping relationship, illustrated in Figure 11. - In those embodiments with the
tamper proof structure 71, the tamper proof member (or stopper flap) 90 is folded inwardly alongfold line 92 andglue patch 96 is secured totop wall panel 12 as shown in Figures 11 and 12. Thus the carton is in a set up and loaded condition ready to be supplied to the end 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 alongfold line 95 as shown in Figure 13. By continuing to lift thetab 94, theglue patch 96 becomes detached fromtab 94 and thetamper proof member 90 is folded back alongfold line 92 as shown in Figure 14; and may optionally be removed by tearing along nick points defined infrangible line 88 to reveal theaccess structure 70, shown in Figure 15. - In order to gain access to the interior of the carton, the
slidable panel 74 is moved in an outward direction X, shown in Figure 16, by pivoting it aboutfold line 80 so thatintermediate panel 76 is swingable and moved aboutfold lines 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.
- It is envisaged that 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. However, it is anticipated that 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.
- It will be recognised that as used herein, directional references such as "top", "base", "end", "side", "inner", "outer", "upper" and "lower" do not limit the respective panels to such orientation, but merely serve to distinguish these panels from one another. Any reference to 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.
- It should be understood that various changes may be made within the scope of the present invention, for example, 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.
