    摘要: A box made of paper material with a lid including a containment body having a base wall, a plurality of containment side walls, an access opening defining a containment space, a lid including a top wall and a plurality of lid side walls. At two non-adjacent containment side walls first portions of a retention device are present and two non-adjacent lid side walls having second portions of the retention device. When the lid is closed, each first portion and respective second portion of the retention device are commutable between a stable mutually engaged condition and an unstable mutually disengaged condition, wherein the stable mutual engagement condition is obtained by interference between each first portion and the respective second portion of the retention device. A rib is placed inside the containment space and placed between the base wall and the access opening.

    摘要: Described are a machine and a method for forming containers from blanks, including a plurality of shaping hoppers, an endless conveyor which defines a feed path and on which the hoppers are mounted in succession and a plurality of pushing elements which are movable in such a way as to follow the respective shaping hoppers along at least a stretch of the feed path and which have a to-and-fro operating movement towards and away from the respective hopper along a direction transverse, preferably perpendicular, to the feed path. The machine also includes folding means disposed along the feed path downstream of the pushing elements and configured to produce, respectively, a top closure and/or a bottom closure of the tubular blank.
