Definitions

  • the present invention relates to a food container made of paper material and a method for making the same.
  • the invention is particularly suitable for supporting and transporting food products such as confectionery products, biscuits, sweet or savoury pastries, sweet products and the like. More in detail, the container can be used to define a support, display and transport element for sweets.
  • trays made of paper material are commercially available and consist of a flat laminar element having a plurality of perforated seats, each of which is intended to receive a corresponding paper ramekin in engagement.
  • the ramekins made of paper are made from a flat sheet of paper material which has been deep-drawn to a three-dimensional configuration. The ramekins are inserted into the holes of the flat laminar element at an outer perimeter edge, e.g. by means of glue.
  • Such containers although capable of holding food products, are not free of limitations and drawbacks.
  • the Applicant has found that some containers are made by means of complex manufacturing processes that require long production times and that produce large amounts of paper waste, both during the production of the laminar element and during the production of each of the ramekins.
  • a further example of a container is described in Italian patent application No. ITMI20060137A1, comprising a first laminar support in paper material arranged parallel to and in engagement with a second laminar support in paper material.
  • Each laminar support has a top surface on which there are respective through cuts delimiting a central portion of circular shape. It has to be noted how the through notches of the first support are aligned with the through notches of the second support along a vertical axis.

It has to be noted how, due to the circular shape of the central portion, it is possible to create a three-dimensional structure following the execution of a single deformation step of the first and second laminar supports.
  • the aim of the present invention is therefore to solve at least one of the drawbacks and/or limitations of the previous solutions.

  • the movement of the first support 2a from the first to the second operative position involves the arrangement of the material interposed between the through-slots 12a of the first support 2a in a three- dimensional configuration to define ribs 8a that are distinct and spaced apart.
  • the ribs 8a lie on an ideal curved surface defining the lateral portion 7a, each extending in interposition between the top surface and the base portion 4a and spaced apart from each other by through openings.
  • Each rib 8a also has a predetermined variable angular extension proceeding from the top portion 5a approaching the base portion 4a, between 60° and 5°, optionally between 50° and 10
  • each rib 8a has a variable angular extension progressively proceeding from the top portion to the base portion 4a along a direction parallel to the axis 11.
  • the ratio between the angular extension of each rib 8a at the top portion and the angular extension of the same rib 8a at the base portion 4a is between 10 and 1, optionally between 7 and 0.8.
  • the containment structure of the first support 2a is housed within the containment structure of the second support 2b, wherein the base portion 4a of the first support 2a is engaged, optionally exclusively in contact or proximity, with the base portion 4b of the second support 2b, wherein the ribs 8a of the first support 2a are superimposed on the ribs 8b of the second support 2b.
  • the ribs 8a of the first support 2a are directed along an opposite winding direction from the ribs 8b of the second support 2b.
  • the ribs 8a of the first support and the ribs 8b of the second support 2b have an inclined course from the respective top portion to the respective base portion to define a lattice structure (see, for example, Figure 8).
  • the support and rigidity of the container is entirely dependent on the support and containment structures of the first and second support 2a, 2b, in this regard, the material constituting support 2 may be an appropriate cardboard, in particular with a grammage between 151 and 400 grams per n .
  • first and second supports have their respective surfaces covered with a layer of plastic material, in particular, the surfaces of the first and second supports in contact with each other and at which they are engaged.
  • this layer of plastic material allows the engagement between the first and second supports2a, 2b, and in particular of the bottom portions 4a, 4b, by means of heat-sealing.
  • the method involves the steps of preparing a first and a second support 2a, 2b made from a single sheet of paper material performed on a single continuous sheet or on a pre-cut discrete sheet (Figure 5).
  • the method may thus provide for the superimposition of the first support 2a to the second support 2b, making it possible to realise the container in line with the first and second supports at least partially engaged with each other.
  • the notches 12a and 12b with opposing (clockwise/counter-clockwise) trends are partially superimposed one above the other at the superimposition area 50, with the bottom portion 4b of the second portion 2b misaligned from the bottom portion 2a of the first support.
  • the method may comprise distinct deformation steps of the first and second supports to define respective containment structures 3a, 3b.
  • the respective deformation steps comprise arranging the material interposed between the respective through notches 12a, 12b of the first and second supports 2a, 2b in a three-dimensional configuration to define the ribs 8a, 8b.
  • the deformation step of the first support is only partially executed at the same time as the deformation step of the second support 2b.
  • the execution of the deformation step of the second support 2b at least partially precedes the deformation step of the first support 2a, the execution of which is partially delayed.
  • the deformation step of the second support 2b includes the sub step of:
  • the substep of rotating the base portion 4b of the second support 2b is executed simultaneously with the substep of pulling the same base portion 4b of the second support 2b.
  • the mechanical organ in engagement with the base portion 4b simultaneously translates and rotates the same base portion 4b with respect to the axis 11.
  • the deformation step of the first support 2a may include a substep of thrusting the base portion 4a of the first support 2b away from the top portion 5a of the first support 2a along a direction parallel to the axis 11.
  • the thrusting step allows the rotation and approach of the base portion 4b of the second support to the base portion of the second support 4b. It has to be noted how the thrusting step is executed after the step of rotating the base portion 4b: the deformation step of the first and second supports 2a, 2b are therefore synchronised but temporally staggered.
  • the substep of thrusting the base portion 4a of the first support 2a further involves placing the same base portion 4a of the first support in contact with the base portion 4b of the second support 2b.
  • an actuator such as a suction cup, engages the second portion of base 4b and pulls it downwards while simultaneously rotating it so that when this portion reaches its final position, the overall angle of rotation is equal to a.
  • a further actuator which nevertheless operates in thrust, begins to push down the first portion of base 4a.
  • the further actuator may be a normal pusher which pushes the first base portion 4a towards the second base portion 4b until it reaches it.
  • the first portion of the base 4a will be free to rotate (i.e. the further actuator does not need to accompany the rotation, it only needs to 'push' the portion) and, when it reaches the second portion of the base, it too will have undergone the same rotation by an angle a, but in the opposite direction so that when the container is completed and finished, the two portions of the base will be superimposed on each other.
  • the method may further comprise a step of engaging the base portion 4a of the first support 2a to the base portion 4b of the second support 2b, executed subsequent to the respective steps of deforming the first and second supports 2a, 2b.
  • the engaging step may comprise heatsealing the defined plastic material layer on the contacting surfaces of the first and second supports 2a, 2b.
  • the engagement of the base portions by means of gluing is not excluded.
