Abstract
There is provided a tightening arrangement in a paperboard wrap for articles such as bottles 11. In the region of the side/base junction there is provided a number of hinge panels 25 which remain hingedly connected to the wrap. The hinge panels 25 are folded out of alignment with the wrap such that a first part 26 lies in use against the adjacent base panel below a heel part 16 of one of the bottles 11. The hinge connection of the hinge panels 25 provides a firm area for engagement by the substantially straight, continuous edge provided by a series of engaging members 52 mounted on an endless chain.
