Definitions

  • the invention relates to a tray - also designated in the art by the term "cradle of wedging" - in a semi-rigid material for the packaging of fruit, vegetables or, more generally, products of various shapes.
  • a packaging method increasingly used for fruits and vegetables consists of housing them in a tray made of a semi-rigid material (cardboard, plastic, etc.), which is then wrapped with its content using a sheet of stretchable or shrinkable plastic or a stretchable plastic net or other type of material.
  • the conditioned objects are thus held firmly in position and it is possible to deliver them to the retailer in the same form where they will be put up for sale, in lots of four, six, eight objects or even more.
  • the present invention aims to remedy these drawbacks by proposing a tray which can be deformed to adapt to the size of the objects to be packaged, while then tightly enclosing them, under the stress of the film of stretchable or shrinkable plastic or of the plastic stretch net.
  • the subject of the invention is a tray made of a thermoplastic material, comprising a bottom and substantially continuous side walls, characterized in that said walls comprise at least one projecting part, forming a bellows and directed inwards or the outside of the tray, preferably with a cut or notch at its upper edge, in order to be able to deform under the stress of the packaged objects and / or the sheath of stretchable or retractable plastic material enveloping said tray and said objects.
  • bellows parts will preferably be arranged at the contact planes of the adjoining objects. Their dimensions can be absolutely arbitrary and, ultimately, two parts of side walls parallels may come into substantial contact with one of the nutres to form a partition between the continuous objects.
  • the deformations of the tray will be substantially elastic.
  • the cuts or notches provided in the upper part or bellows are naturally intended to facilitate the deformation of these bellows.
  • the tray may deform laterally and longitudinally, expanding and flaring, to adapt to the dimensions of the objects, without injuring them, which will be held firmly in position by the shrink or stretch film or by the stretch plastic net or any other material, which stresses them as well as the tray.
  • the tray will be compressed by said film to contract and thus adapt to the size of the objects.
  • the tray shown in the drawings is produced by thermoforming a thermoplastic material (polyvinyl chloride or the like) and has a generally rectangular section. It has a bottom 1, two longitudinal walls 2 and two transverse walls 3 connecting to the previous ones continuously in the corners by curved parts 4.
  • This tray is intended to receive two rows of three fruits and, to separate the sweet rows longitudinally, the bottom 1 has a projecting part 5, forming a partition.
  • the longitudinal 2 and transverse 3 walls include projecting parts, respectively 6 and 7, cut at their upper part, respectively at 6 'and 7'.
  • These projecting parts are arranged along the contact planes of the various objects, thereby defining cells for the accommodation thereof.
  • Their dimensions can be absolutely arbitrary, depending on the desired effect.
  • These parts can possibly be engaged between the objects to be packaged and thus ensure their separation.
  • the invention therefore provides a simple and inexpensive means of adapting the size of the trays to that of the fruits, vegetables or other objects housed therein, thus making it possible to package in the same type of tray and to overwrap with plastic film objects of different sizes, without complicating the packaging operations and virtually eliminating the risk of deterioration of these objects.
  • the tray according to the invention is therefore particularly useful.
