Definitions

  • the present invention relates to a container for pre-cooked and/or ready-to-eat food.
  • Plate-shaped or tray-shaped containers made of heat-resistant polymeric material are generally used for this purpose (DE-A-3 919 120), their content being protected with a thin film of plastic material which adheres to the planar edge of the container and can be removed by the consumer by so-called “peeling”, which consists in exerting, on said film, a traction directed at an appropriate angle with respect to the adhesion plane defined by the container edge, which is briefly termed “suture plane” hereafter.
  • the film generally separates by initially applying a traction force having a certain inclination -- equal to approximately 45° -- with respect to the suture plane and this, though on one hand it constitutes a positive circumstance in terms of the correct and easy removal of the film, on the other hand it constitutes a hardly negligible disadvantage in terms of the protection of the product.
  • the protective film in fact inflates, assuming a substantially lens-like convex shape, so that stresses are generated at the regions of suture to the edge of the container, and their orientation can reach and exceed said limit inclination, consequently producing the progressive and spontaneous separation of said film and therefore compromising the correct seal of the package.
  • the aim of the present invention is to eliminate the above described disadvantage without however compromising ease in opening the package.
  • An object of the present invention is to improve the protection of the packaged food, preventing incidental tearings of the film, by means of a lid which can be easily applied by machines suitable for continuous production processes and is just as easily removable by the consumer without compromising the integrity of the container.
  • 10 generally indicates the base half-shell, which comprises a cup-like tray 11 surrounded by a protruding edge 12, said half-shell, which is preferably made of heat-resistant polymeric material, being suitable to act as a plate for eating the food packaged therein.
  • the plan profile of the shell 10 is curvilinear and pseudo-rectangular, and is defined by pairs of opposite homologous sides L,L' constituted by arcs of a circle which have respective differentiated radii.
  • the edge 12 substantially has the same profile as the half-shell, from which it differs due to the presence of widened grip portions 12a which surround the larger sides L'.
  • the edge 12 is furthermore concave, at least at the grip portions 12a, and ends with a slightly undercut lip 12b.
  • the concavity of the edge 12 defines a curved suture surface 14 for a protective film 15 made of plastic material, of a per se known kind, which can be removed by so-called "peeling".
  • the concavity of the surface 14 is chosen so that it is, at least in the region of connection of the edge 12 to the tray 11, tangent or approximately tangent to the geometrical solid SG along which the film 15 arranges itself when it is stressed by the pressure of the steam produced by any thermal treatment of the food packaged in the container. Therefore, in the presence of steam, the film is subjected to a traction which is parallel to the suture surface at the specified region, and this, in accordance with the aim and objects of the invention, prevents the progressive and spontaneous separation of said film from the edge 12.
  • the curvature of the suture surface 14 is such that the tangent to said surface, in said region of connection to the tray 11, is approximately 30° with respect to the plane P which is tangent to the edges of the container.
  • a removable lid 20 (figure 4) co-operates, for food protection, with the base half-shell 10, is likewise made of polymeric material and can be snap connected to the underlying base half-shell.
  • the lid which is also cup-shaped, has an edge 21 the plan profile whereof coincides with the plan profile of the edge 12 of the base half-shell on which said lid can be superimposed.
  • Pairs of raised portions or opposite teeth 22 are formed on the edge 21 of the lid, are arranged substantially at the regions of connection between the curvilinear sides of the edge and are adapted to engage in a snap fashion, by virtue of the elastic deformability of the material of the container, the undercut lip 12b provided on the edge 12 of the base half-shell 10.
  • the removal of the lid is performed just as easily by virtue of the particular plan profile of the container.
