Definitions

  • the present invention relates to a method for manufacturing self-standing containers made of paper-like material for oven baking, displaying and selling foodstuffs, especially confectionery products, to the apparatus for carrying out the method and to the containers obtained with said method.
  • containers of the following types are used: metal baking pans, either plain or with optional containers of pleated paper, known as dessert coasters, inserted in them; self-standing containers of corrugated paper, known as baking molds; and aluminum containers.
  • the aim of the present invention is substantially to eliminate these and other drawbacks, and within the scope of this general aim the invention has the following particular objects:
  • the invention is based on the concept of providing in succession, by acting with a single die-cutting action and by means of a composite tool, the following operating steps:
  • the composite die-cutting tool comprises the following coaxially arranged components: a circular die-cutter, with a cutting edge made of inserted hard metal, in order to cut said disk of paper-like material; a female mold part which can move axially and cooperates with the circular plate of a complementarily shaped male mold part, for drawing the disk of paper-like material produced by die-cutting; a beading ring, which is arranged outside the female mold part and can move axially in an annular gap that lies between the male and female mold parts when they are mutually adjacent and is adapted to engage the excess perimetric flap that surrounds the drawn disk in order to push said flap, for rolling up, swaging and compacting, into a corresponding annular cavity which is provided in said male mold part and surrounds said circular plate.
  • the container produced with the manufacturing method according to the invention is therefore characterized by a monolithic drawn paper-like structure having a reinforced rim which has a self-standing function and is produced by rolling, swaging and compacting a perimetric flap of the side wall or walls, provided in excess with respect to the depth of the finished container.
  • the reference numeral 10 designates the reel for storing a ribbon 11 of paper-like material, typically vegetable parchment, preferably composed of two bonded sheets which have respective basic weight of substance of 60 and 95 g/m 2 , or other equivalent or similar material.
  • the ribbon 11 is fed continuously to an apparatus 20 which provides in succession by means of a single die-cutting action: cutting of a disk D of paper-like material from the ribbon 11; drawing of said ribbon and swaging of the free edge B of the drawn disk.
  • the apparatus 20 is composed of a plurality of elements which are arranged coaxially and are substantially constituted by:
  • the complementary walls of the female mold part 23 and of the circular plate 22a are smooth, but this is a non-limitative configuration, since said walls can be provided with ridges or dentellations parallel to their generatrices in order to produce containers having correspondingly ribbed or pleated walls.
  • Conventional means which are not shown and preferably comprise double-acting fluid-actuated actuators, are provided in order to vertically move the female mold part 23 from an open position ( Figures 1 and 2), in which said mold part is spaced from the circular plate 22a, to a closed position, in which it is lowered onto said circular plate ( Figures 3 and 4). Further conventional actuation means are provided in order to move the beading ring 24 vertically, so as to form said rim B and move the circular plate 22a with respect to the fixed mold part 22 in order to extract the finished container 30 ( Figure 5).
  • the container 30 produced with the above described manufacturing method is accordingly characterized by a monolithic paper-like drawn structure which has a reinforced rim B which gives said container mechanical self-standing characteristics, said rim being the result of the rolling and swaging of a perimetric flap LP of the lateral wall of the container, which is provided in excess with respect to the depth P thereof.
