Definitions

  • the present invention relates to a method for making a display container for foodstuffs and the display container made using this method.
  • containers also acting as display trays
  • foodstuffs such as meat, vegetables, fruit, desserts, etc.
  • the inner surface of the container may have an additional coating made of plastic (for example PET or PE), which acts as a barrier protecting the product from greases, liquids and, partly, from gases, so that the underlying cellulose structure is not affected.
  • plastic for example PET or PE
  • a foodstuffs container comprising, among other things, an edge extending continuously to constitute a closed surface forming the upper perimeter of the container; on this edge it is possible to associate a strengthening element divided into a first part which can be stably associated with a portion of the edge close to its connection with the walls, and a second part which can be associated with a portion of the walls close to the edge.
  • These two parts of the strengthening element extend in such a way as to partly cover the edge and the walls, forming an additional surface or layer designed to allow stiffening of the edge - walls zone.
  • said solution allows a definite increase in the rigidity of the cellulose container with excellent results for containing products of various types, and in particular for products protected in a controlled environment.
  • this type of container is normally used to contain products of a certain quality and type whose production can absorb or justify its cost.
  • the aim of the present invention is therefore to overcome these disadvantages by providing a method for making a foodstuffs container with excellent mechanical features and reduced unit costs, and the relative container made using this method.
  • the present invention provides a method for making a container which is very rigid and has low unit costs and the relative container made using this method and comprising the technical features described in one or more of the claims herein.
  • Said container labelled 1 as a whole, consists of a casing basically comprising a flat base 2 and a set of walls 3 substantially perpendicular to the flat base 2, the bottom of the walls being connected to the base 2 to form a cavity C for holding the product.
  • the shape of the container 1, of the quadrangular type here may be any shape without that limiting the solution disclosed.
  • tops of the walls 3 form an upper edge 4, extending continuously along the contour of the container 1.
  • the method for obtaining this type of container 1 comprises the following steps (see Figures 3 to 5):
  • the projection 5 preferably, but without limiting the scope of the invention, extends around the entire perimeter of the edge 4.
  • this bending step may cause the projection 5 to be placed over the lower surface 4c of the edge 4 (see Figure 10).
  • Figure 3 shows how, during the container 1 forming step, the projection 5 may be positioned transversally (or perpendicularly) to the edge 4.
  • the projection 5 may be positioned at an angle to or coplanar with the edge 4.
  • a pre-bending line L may be made (clearly visible in Figure 10) between the projection 5 and the outer end of the edge 4, to facilitate the step of bending the projection 5 towards the edge 4 (see arrows F5 and F5a).
  • This step of bending the projection 5 on the edge 4 may be carried out mechanically by pusher means 7 schematically illustrated in Figure 5.
  • the above-mentioned step of joining the projection 5 on the edge 4 may be carried out using heat-sealing (see Figure 5 with sealer 50), or with suitable adhesive dispensed by relative means 8 (see Figure 4), before the bending step.
  • the step of bending the projection 5 may generate a perimetral bulge 9, at the pre-bending line L between the edge 4 and the projection 5. In this way, it is possible to obtain considerable strengthening on the outside combined with the formation of a zone for gripping the container 1.
  • Figures 6, 7 and 8 show three different final configurations of the projection 5 placed over the edge, for example, on the upper surface 4a, but this also applies if the projection 5 is bent and placed over the lower surface 4c.
  • the length S3 of the projection 5 may be equal to the length S of the edge 4, and consequently it is bent over the entire upper surface 4a of the edge 4.
  • the length S1 of the projection 5 may be greater than the length S of the edge 4, and consequently it is bent both over the upper surface 4a of the edge 4 and over an upper portion of the walls 3.
  • the length S2 of the projection 5 may be less than the length of the edge 4, and consequently it is bent over a portion of the upper surface 4a of the edge 4, in such a way as to leave the other portion of the upper surface 4a of the edge 4, connected to the upper part of the walls 3, without the projection placed over it (for example for any positioning of covering elements which may be used).
  • the projection 5 may be positioned on part or all of the perimeter of the edge 4.
  • Figure 9 shows two different solutions in which the projection 5 only partly extends: in the first the projection 5, shown with a continuous line, is present for example on straight stretches of the edge 4, whilst a dashed line shows another solution in which the projection 5 is interrupted close to the edge 4 joining corner.
  • Figures 1 and 2 show pre-bent zones 5a of the projection 5 (which can be created for example during the moulding step) to allow more rapid and secure bending of the projection.
  • the first stretch 4b is inserted between the walls 3 and the second stretch 5.
  • the second stretch 5 may be bent, that is to say placed over the upper surface 4a or the lower surface 4c of the first stretch 4b.
  • edge 4 of the container may have an outer zone, formed by bending the second stretch 5, forming a perimetral bulge 9 shared by both 4b and 5.
  • This shared outer zone ZE of the first and second stretches 4b and 5 may form perimetral protrusion which is angled downwards.
  • edge 4 may have three different configurations depending on the length of the projection 5.
  • the length S3 of the projection 5 may be equal to the length S of the edge 4, and consequently it is bent over the entire upper or lower surface 4a or 4c of the edge 4.
  • the length S1 of the projection 5 may be greater than the length S of the edge 4, and consequently it is bent both over the upper or lower surface 4a or 4c of the edge 4 and over an upper portion of the walls 3.
  • the length S2 of the projection 5 may be less than the length of the edge 4, and consequently it is bent over a portion of the upper or lower surface 4a or 4c of the edge 4, in such a way as to leave the other portion of the upper surface 4a of the edge 4, connected to the upper part of the walls 3, without the projection placed over it (for example for any positioning of covering elements which may be used if affecting the upper surface 4a).
