Stackable tray

Abstract

A stackable tray includes a tray body, which is formed by a cardboard blank including a heat resistant cardboard. The stackable tray includes a guiding element configured for providing a shifting of a first tray relative to a similar second tray located below the first tray in a first direction parallel to its surface, when first tray is stacked on a similar second tray; and the guiding element provides for preventing a shifting of the first tray relative to the similar second tray in a second direction substantially perpendicular to the first direction and substantially parallel to its surface.

1 . Stackable tray, comprising: 
 a) a tray body, the tray body being formed by a cardboard blank including a heat resistant cardboard;    b) a guiding element, the guiding element being configured for providing for a shifting of a first tray relative to a similar second tray located below the first tray, in use, the shifting of the first tray being in a first direction parallel to its surface, when the first tray is stacked on the similar second tray; and    c) the guiding element being configured for substantially preventing a shifting of the first tray in a second direction relative to the similar second tray located below the first tray, in use, the substantially preventing of the shifting of the first tray in the second direction being substantially perpendicular to the first direction, when the first tray is stacked on the similar second tray, and the substantially preventing of the shifting of the first tray in the second direction being substantially parallel to its surface.    
   
   
       2 . Stackable tray as claimed in  claim 1 , wherein: 
 a) the guiding element includes at least two tongue-like guiding elements, the tongue-like guiding elements extending from opposing side edges of a tray body of the first tray, the tongue-like guiding elements extending from a lower side of the tray body, and tongue-like overlap the tray body of the second tray stacked below the first tray on both sides of the second tray, in use.    
   
   
       3 . Stackable tray as claimed in  claim 2 , wherein: 
 a) on at least one side edge of the tray body of the first tray, the guiding element includes at least two guiding elements, and the at least two guiding elements are spaced relative to each other.    
   
   
       4 . Stackable tray as claimed in  claim 2 , wherein: 
 a) on two opposing side edges of the tray body, at least two guiding elements are located, and the guiding elements are spaced relative to each other.    
   
   
       5 . Stackable tray as claimed in  claim 2 , wherein: 
 a) the tray body includes walls, the walls include opposing walls, and from the opposing walls which are located at a side edge, respectively, and at which at least one guiding element is located, at least one further guiding element extends upwardly.    
   
   
       6 . Stackable tray as claimed as claimed in  claim 2 , wherein: 
 a) at least one of the guiding elements is integral with the tray body.    
   
   
       7 . Stack of trays as claimed in  claim 6 , wherein: 
 a) the stack includes at least two of the first and second trays, the at least two of the first and second trays being stacked on each other.    
   
   
       8 . Stack of trays as claimed in  claim 5 , wherein: 
 a) the stack includes at least two of the first and second trays, the at least two of the first and second trays being stacked on each other.    
   
   
       9 . Stack of trays as claimed in  claim 1 , wherein: 
 a) the stack includes at least two of the first and second trays, the at least two of the first and second trays being stacked on each other.
