Abstract: The present invention relates to a container having a tub body (2; 36) with a bottom (3), a side wall (4), and a lid (5; 37) with top wall (6) and side wall (7). The side walls of both the container and the lid have complementary flanged rims that can fit together by snap engagement with one another. The rim (8) of the body of the container has, in sequence, a first flat flange section (11) extending outwards on the one hand, integral with the side wall (4) of the body of the container and, on the other hand, an inwardly bent section (12) at least partly extending over said flat section (11), an intermediate outwardly convex section (13), a second flat flanged section (14) substantially parallel to the first flat section (11), and a protruding terminal volute-shaped section (15) delimiting an uninterrupted undercut recess (16) with the second flat section (14).

Abstract: A plant for unloading stacks (5) of thermoformed products from a cage (4) containing stacks (5), which comprises a support structure (2), at least one support plate (3) for a respective cage (4) containing stacks (5), which is mounted for rotation on said support structure (2), drive means (8) to cause said support platen (3) to effect angular movements of a preset amplitude around a horizontal axis, so as to angularly move its respective containing cage (4) between an erect position, in which the stacks (5) of thermoformed products contained therein extend in a substantially vertical direction, and an inclined unloading position, expeller means (12) designed to expel stacks (5) of thermoformed objects from said cage (4) when said support plate (3) is in inclined unloading position, and a conveyer (20) for receiving stacks (4) of thermoformed objects unloaded from said containing cage (4) located downstream of the unloading position of said support plate (3).

Abstract: A handling apparatus for groups of thermoformed objects constantly held in a correct axial alignement, which apparatus includes at least one picking up-release head (2) having as many receiving seats extending parallel to one another from said head (2) as are the stacks (4, 4a, 4b) to, be handled, and drive means (7, 19) arranged to move a respective pick up and release head (2) between a stack pick up station (10) and a stack release station (12, 17) of one or more stacks (4) of thermoformed objects and to position it correctly both at the said stack pick up station (10) and at the said stack release station (17, 12), at least one mobile pusher member (21) arranged to be moved between, and parallel to, the said receiving seats in order to engage at the top thereof the stacks (4, 4a, 4b) of thermoformed objects (5) located in each receiving seat, and control drive means (23) for each mobile pusher member (21), thereby following and hold down each stack (4, 4a, 4b) while the same is being released from its res
