Tray-shaped packaging

Abstract

The invention relates to a tray-shaped packaging for food comprising a bottom and a circumferential margin. The bottom comprises at least one collecting section and at least one supporting section, wherein the support section comprises a plurality of elevations for carrying a product, and wherein the collecting section at least in a certain area has a greater depth relative to the margin of packaging than the support section.

What is claimed is: 
     
         1 . Tray-shaped packaging for a product, the tray-shaped packaging comprising:
 a bottom having at least one collecting section and at least one support section, wherein the at least one support section includes a plurality of elevations for supporting the product; and   a circumferential margin;   wherein the at least one collecting section at least in certain areas has a depth relative to the margin that is greater than a depth of the support section to the margin.   
     
     
         2 . Tray-shaped packaging according to  claim 1 , wherein the support section is arranged between at least two collecting sections. 
     
     
         3 . Tray-shaped packaging according to  claim 1 , wherein the support section is circumscribed entirely by a collecting section. 
     
     
         4 . Tray-shaped packaging according to  claim 1 , wherein the elevations are pin-shaped, pyramid-shaped, rib-shaped or dome-shaped. 
     
     
         5 . Tray-shaped packaging according to  claim 1 , wherein the elevations are arranged in the form of a matrix with n lines and m columns, wherein n and m are integers and each larger than 1, preferably n and m≧4, respectively. 
     
     
         6 . Tray-shaped packaging according to  claim 1 , wherein each elevation comprises a peak and wherein the peaks of all elevations of each support section are arranged in a common plane. 
     
     
         7 . Tray-shaped packaging according to  claim 1 , wherein drainage channels leading towards the at least one collecting section are provided between the elevations. 
     
     
         8 . Tray-shaped packaging according to  claim 7 , wherein the drainage channels have a downward slope towards the collecting section. 
     
     
         9 . Tray-shaped packaging according to  claim 1 , wherein the support section of the bottom is convex on its side facing the interior of the packaging. 
     
     
         10 . Tray-shaped packaging according to  claim 1 , wherein a step is arranged between the support section and the collecting section. 
     
     
         11 . Tray-shaped packaging according to  claim 1 , wherein the packaging is heat resistant up to a temperature of at least 150° C. 
     
     
         12 . Tray-shaped packaging according  claim 1 , wherein the bottom and the margin of the packaging are made from a PET foil. 
     
     
         13 . Tray-shaped packaging according to  claim 1 , wherein the bottom and the margin of the packaging are made from a bi-axially oriented PET foil. 
     
     
         14 . Deep drawing station for producing a tray-shaped packaging, said deep drawing station comprising a forming tool adapted for deep drawing a tray-shaped packaging with a bottom and a circumferential margin, such that the bottom comprises at least one collecting section and at least one support section, wherein the support section comprises a plurality of elevations for supporting a product and wherein the collecting section at least partially has a depth relative to the margin of the packaging that is greater than a depth of the support section relative to the margin.
