An open-topped container 1 e.g. a salad bowl has a bottom wall 2 with a raised plinth 6, the circumference of which is at least partially defined by a channel 7, a wall 9 of which extends downwardly from the plinth. Also claimed a mould system for thermoform manufacture of such a container comprising a male mould over which a single sheet of heated thermoformable material is formed, the lowermost section of the mould equating to the uppermost section of the container i.e. the container is thermoformed upside down. The container may be made from aPET, rPET, polypropylene, PVC and/or styrene. The channel may be 6-10mm deep and less than 3mm wide. The container may have an internal de-nesting feature comprising the wall 9 of the channel being angled to form an undercut structure and a locating groove 17, on which a similar container will rest when stacked (Figure 5).The container may have a hinged lid which is push-fit to close at a sealing flange 12, such that it is leak resistant. |
