| 摘要 |
The invention concerns a container obtained by folding a sheet (2) of semirigid material such as paper or cardboard, along pre-folding lines formed in said sheet and by closure with a linking element passing through holes perforated near the terminal edges of said sheet. The pre-folding lines define: (a) a first central zone (6) in the shape of a polygon with N sides, (b) N substantially rectangular second zones (7) adjacent to the N sides (18) of the first central zone (6) and, (c) N sets of third folding zones arranged between the N second zones. The invention is characterised in that in each set there are n third folding zones (8), n being an even number, each formed by an angular portion whereof the apex is more or less one the apices (9) of the central polygonal zone (6); furthermore, there are as many holes (10) as third folding zones (8) and the holes (10) are located in said third folding zones (8) such that, when the container (1) has been completely folded, the n holes (10) of a common set of third folding zones (8) are aligned outside the volume formed by the N second zones (7). |
