Definitions

  • the present invention relates to a method for producing a tray and to a tray, in particular a serving tray, with a layer provided on its surface according to the preambles of claims 1 and 12.
  • the layer is applied to the surface of the tray body by a spraying, spraying or brushing process. It is also known to insert a film to form a layer in an injection mold and to inject it back with the tray body.
  • the present invention is concerned with the task of coating trays or for coating with a layer so that the layer can be applied inexpensively and without errors to the tray body. According to the invention, this object is achieved by the method steps of claim 1 or by the features of claim 12.
  • the coating is produced efficiently and cost-effectively and the inclusion of air and the occurrence of air bubbles between the tray body and the layer or layers is reliably avoided. Furthermore, through the selection of the number and size of the openings in tray and coating material and thus also in weight can be saved. In addition, the type of coating can be determined by the choice of the size of the openings.
  • the tray body has a flat bottom
  • FIG. 1 a shows a cross section through a plunge pool for coating the tray body
  • FIG. 3 is an enlarged view of the circular section B of FIG. 1,
