• the end panels BP2, BP3 each includes a cut out portion that corresponds in shape to the top and bottom parts RP2, RP3 of the portion RP.
• Figure 8 shows a perspective view of a partially erected packet comprising two half-assembled packets IA, IB, wherein each half-assembled packet IA, IB is made using the set of blanks illustrated in Figure 6.
• a method of folding the rightmost blank BR to produce the half-assembled packet IA involves the following steps: a) Fold the top lid panel BR3B, the bottom lid panel BR3C, the bottom end panel BR4 of the container portion BRC and tabs BRTl, BRT2, BRT3, BRT4, BRT5 through ninety degrees so that they upstand from the panels to which they are attached; b) Fold the side lid panel BR3E through ninety degrees relative to the main lid panel BR3A ensuring that the already folded tabs BRTl, BRT2 are guided to make contact with the inside surface of the top lid panel BR3B and the bottom lid panel BR3C respectively; c) Fold the main panel BR3 A through ninety degrees relative to the side lid panel BR3D ensuring that the tabs BRT3, BRT4 are guided into contact with the inner surface of the top lid panel BR3B and the bottom lid panel BR3C respectively; d) Fold the side panel BR3 of the container portion BRC through ninet
• the two bottom panels BR4, BL4 come together with substantially abutting edges to form a base of the container 11 in the erected packet 1 ; i) Fold the partition blank BP by folding both side panels BP2, BP3 through ninety degrees relative to the main panel BPl and insert the formed partition I IP into the container 11 by sliding the partition I IP through the open top end to divide the container 11 into two equal sized compartments; j) Rotate both lids 3, 5 to close the packet 1.
• the contents of the packet may be placed on the blanks at step a) and the blanks can be folded around the contents.
• the contents could be placed in each container portion BRC, BLC of each half-assembled packet IA, IB prior to step h) when the half-assembled packets IA, IB are combined.
• the contents may be inserted through the open top end prior to step j) when the lids are rotated to close the packet 1.
• the container 11 When the set of blanks as illustrated in Figure 7 is folded and combined the container 11 is wholly closed. Therefore, during assembly of the half-assembled packets IA, IB the contents and the partition are inserted during the assembly process prior to combining the two half-assembled packets IA, IB.
• the packets described herein, for example as shown in Figure 1 are closer to a square cross-section than conventional hinged-lid packets. This can lead to more rigidity and protection of the enclosed product. It may also be feasible to reduce the amount card required to make the blank.
• the lid arrangement of Figure 1 avoids any problems with interference between the lid and the body of the pack (which might potentially arise if a conventional lid mechanism were to be used with a much fatter packet arrangement).
