Optionally, side walls 1 10, 1 12 each comprise a plurality of first and second apertures 142 and 140. First apertures 142 are circular whereas second apertures 140 are rectangular. First and second apertures 142 and 140 are provided to allow ventilation of the package, and/or to provide windows for viewing parts of cartons 8, for example display or advertising panels, when cartons 8 are disposed within the secondary package 2. First and second apertures 142, 140 also serve to reduce the weight of the secondary package 2. First and second apertures 142, 140 may also be engaged by a packaging machine during assembly of the secondary package 2. Side end closure flaps 1 18/124 and 120/122 are coupled to side walls 1 10, 1 12 respectively along respective fold lines 121/1 1 1 and 1 17/1 15.

Base end closure flaps 1 14, 1 16 are coupled to the base structure along fold lines 1 19 and 1 13 respectively.

An elongate aperture 148 is struck from each base end closure flap 1 14, 1 16. The elongate aperture 148 is disposed centrally within each base end closure flap 1 14, 1 16. A lower portion of each elongate aperture 148 is coincident with and interrupts fold lines 1 19 and 1 13. Elongate apertures 148 form a handle structure 150.

The base structure comprises four detachable base panels 132a, 132b 132c and 132d disposed between a pair of support members 126, 128/130. Detachable base panels 132a, 132d are disposed between support members 130, 126 where support member 130 is disposed at one end of the base structure in hinged connection with end closure flap 1 16 and along fold line 1 13 and support member 126 is disposed centrally within base structure and in hinged connection with side walls 1 10, 1 12 along portions of fold lines 125 and 127 respectively.

Detachable base panels 132b, 132c are disposed between central support member 126 and support member 128. Support member 128 is disposed at an opposed end of the base structure and is in hinged connection with base end closure flap 174 along fold line 1 19. Engaging aperture 144a separates detachable base panels 132a and 132d and engaging aperture 144b separates detachable base panels 132c and 132b. Engaging apertures 144a is disposed between end support member 130 and central support member 126, whereas engaging aperture 144b is disposed between end support member 128 and central support member 126.

Detachable base panels 132a, 132b, 132c 132d are maintained in connection with support members 126, 128, 130 via nick portions 170, or other frangible connection means, disposed substantially at each corner of the detachable base panels 132a, 132b, 132c,132d.

Engaging aperture 146a, 146b, 146c, 146d separate detachable base panels 132a, 132b, 132c, 132d from their respective adjacent side wall 1 10, 1 12. In the preferred embodiment, engaging apertures 146a, 146b, 146c, 146d are struck from the respective adjacent side wall 1 10, 1 12 and form one part of a complementary interlocking mechanism for interlocking multiple secondary packages 2 when stacked one upon another. Engaging apertures each 146a, 146b, 146c, 146d, form an engaging edge 168 which engages with an edge of a second part of the complementary interlocking mechanism.

The second part of the complementary interlocking mechanism is formed by tabs 160 which are disposed on upper edges of the side walls 1 10, 1 12. When multiple secondary packages 2 are stacked one upon another the tab 160 from a lower secondary package 2 engages with the portion of engaging aperture 146a, 146b, 146c, 146d struck from the respective adjacent side wall 1 10, 1 12 of an upper secondary package 2, thereby preventing longitudinal movement of the upper secondary package 2 relative to the lower secondary package 2.

Transverse interlocking supports are provided in part by tabs 162 disposed on upper edges of side end closure flaps 1 18, 120, 122, 124 and in part by apertures 166 struck from lower end closure laps 1 14, 1 16 and base structure and in part rebate portions 164 when secondary packages 2 are stacked on side end closure flaps 1 18, 120, 122, 124. Tabs 162 engage with the recess 166 formed in base end closure flaps 1 14, 1 16.

The rebate portions 164 of side end closure flaps 1 18, 120, 122 124 are in registry with aperture 166 in the assembled secondary package 2 such that the side end closure flaps 1 18, 120, 122, 124 do not interfere with the transverse interlocking mechanism formed by apertures 166 and tabs 162.

Turning now to Figure 3 there is shown a perspective view of the base of a carton 1 which forms a primary package for a group of articles A. It can be seen that the blank 10 of Figure 1 has been wrapped around the top and sides of a group of articles A. One of the detachable base panels 132a from blank 100 has been secured to the securing flaps 18a, 18b by means of adhesive or other mechanical fixing means known in the art.

Figure 4 shows a perspective view of the base of the secondary package 2, it can be seen that four blanks 10 have been assembled around four distinct groups of articles A. The blanks 10 have been secured to a respective one of the detachable base panels 132a, 132b, 132c, 132d.

The packaging system 4 shown in Figure 4 is assembled by forming groups of articles A and bringing them over a respective one of the detachable base panels 132a, 132b 132c, 132d and bringing a blank 10 over each group of articles A prior to or simultaneously with the step of bringing the group of articles A over the blank 100. The side panels 1 10, 1 12 of the blank 10 are folded about each group of articles A prior to placing groups of articles A upon the blank 100.

Securing flaps 18a, 18b of each of the blanks 10 are received in engaging apertures 146a, 146b, 146c, 146d and 144a, 144b respectively.

Securing flaps 18a, 18b are then secured to the detachable base panels 132a, 132b, 132c, 132d. At the same time as, or subsequently to, folding and securing the securing flaps 18a, 18b to the blank 100 the side walls 1 10, 1 12 are folded about all of the groups of articles A thereby formed.

The side end closure flaps 1 18, 120, 122 and 124 are then folded about their respective fold lines 121 , 1 17, 1 15, 1 1 1 to be perpendicular with a respective sidewall 1 10, 1 12.

The base end closure flaps 1 14 1 16 are then folded about fold lines 1 19, 1 13 respectively to be disposed in face contacting relationship with respective side end closure flaps 1 18, 120, 122, 124. The base end closure flaps 1 14, 1 16 are secured to the side end closure flaps 1 18, 120, 122, 124 by means of adhesive or other mechanical locking means known in the art.

The assembly process forms a packaging system 4 having, in the preferred embodiment, a plurality of independently packaged groups of articles A, each independently packaged group of articles A shares a respective portion 132a, 132b,

132c, 132d of the base panel of the secondary package 2 (best illustrated in Figure

5), this respective portion 132a, 132b, 132c, 132d of the base panel of the secondary package 2 forms a detachable base panel 132a, 132b, 132c, 132d of carton 1 as is best illustrated in Figures 3. When a group of articles A is removed from the secondary package 2 the respective portion 132a, 132b, 132c, 132d of the base panel of the secondary package 2 is separated from the remainder of secondary package 2 as illustrated in Figure 3. This is achieved by breaking the frangible connection 170 between one of the respective portion 132a, 132b, 132c, 132d and the respective support members 126, 128/130.

Each separate independently packaged group of articles A comprises a carton 1 and twelve articles A arranged in a double tier stack of a two by three array of articles A. In the assembled packaging system 4, the chamfered corners 28 provide an edge 29 which prevent the primary package or carton 1 falling from the secondary package 2 should the frangible connections 170 coupling a detachable base panel 132a, 132b, 132c, 132d break undesirably during transit. The chamfered corners 28 also allow the blank 10 to be easily manipulated during assembly such that securing panels 18a, 18b can protrude sufficiently through engaging apertures 146a, 146b, 146c, 146d, whilst being secured to the respective detachable base panel 132a, 132b, 132c, I32d.

It will be understood by those skilled in the art that the chamfered corners 28 are optional and that square corners may be provided which would alternatively prevent the primary package falling from the secondary package 2.

It will be apparent to those skilled in the art that apertures 140 and 142 are entirely optional.

Figure 6 illustrates an alternative embodiment of the present invention in which like features have been assigned the same reference numerals as the previous embodiment but with the prefix "3" appended. It can be seen that the support panels 326, 328 and 330 have been manufactured to have straight edges rather than the wave like shaped nature of panels 126, 128, 130 shown in the embodiment of Figure 4.

The support panels 126, 128, 130 of the embodiment shown in Figure 4 have recessed edges located to be substantially in registry with the corners of the base panel 132a, 132b, 132c, 132d of the primary carton 1 , which primary carton 1 comprises detachable panel 132a, 132b, 132c, 132d and which detachable panels are substantially "I" shaped.

It will be appreciated by those skilled in the art that detachable panels (not shown) for use with the embodiment of Figure 6 may be shaped so as to complement the support panels 326, 328, 330 and therefore need not take the "I" shaped form of the embodiment of Figure 4.

Furthermore, it will be appreciated by those skilled in the art that the base panel of the embodiment shown in Figures 2 and 5 when viewed in the manner shown in Figure 6 will be substantially similar to that shown in Figure 6, except for the support panels 126, 128, 130 which will be curved or wave like in shape.

It will be appreciated by those skilled in the art that alternative configurations could be employed for example each separate group need not be limited to having a double tier or each tier to having a two by three array of articles A. In the preferred embodiment each array of articles is frangibly connected to at least one other article A in the array however this need not be so and the articles A may not be coupled to one another.

Furthermore the packaging system 4 need not result in a group of four groups of cartons in a two by two array as shown in Figure 5 but may be any configuration desired for example a three by one array. Accordingly detachable panels 132a will be sized, shaped and configured to accommodate the size shape and configuration of the primary carton 1. In another embodiment the cartons 1 accommodated by the secondary package 2 are sized and/or shaped differently to one another and detachable panels 132a, 132b, 132c, 132d are sized and shaped accordingly.

It will be further appreciated that one of the benefits of the present invention is that the amount of secondary packaging to be disposed of in store is reduced.

Any directional references used in the above description are incorporated for clarity only and are not intended to be limiting. It will therefore be recognised that as used herein, that terms such as "top", "base", "side ", "end", "inner", "outer", "upper", and "lower" with respect to the panels of the relative terms , and that the carton formed from the blank may be reoriented as necessary or as desired. Any reference to a hinged or foldable connection should not be construed as necessarily referring to a single fold line only: indeed, it is envisaged that a hinged or foldable connection can be formed form one or more of the following, a score line, a frangible line or a fold line, without departing from the scope of the present invention. It is specifically contemplated that the arrangement may be incorporated into other carton types such, as, for example, fully enclosed cartons.
