Rigid/flexible molded plastic/thermoplastic object e.g. plastic foodstuff preserving box, has hooks projecting in two rows, where each row has successive hooks in respective right/left directions with heads projecting in opposite directions

摘要

The object has surfaces (2) from which hooks (6-8, 6`-8`) project, where each hook is constituted by a head section projecting laterally from a stem section. The hooks (6-8) are arranged in a row (4) and the hooks (6`-8`) are arranged in a row (5). Each row has m successive right/left hooks (6, 6`) with heads projecting from the stems in a direction, and n successive hooks in another left/right direction, following the m hooks, with the heads projecting in another left/right direction opposite to the former, where m and n are integers such that m is greater than/equal to 1 and less than n.
