Tray with height selection system

Abstract

The present disclosure relates to injection-moulded trays or containers with a revolving height adjustment system which allows the achievement of two or more different heights that are to be chosen and also provides stability during stacking.

1 . A tray ( 1 ) with a height selection system ( 2 ), wherein the tray comprises:
 a front wall ( 1   e ) which is a flat plate;   a back wall ( 1   h ) which is a flat plate;   two side walls ( 1   f ) each one optionally having a hollow ( 1   g ) for manual handling;   said walls ( 1   e ,  1   h  and  1   f ) are projecting from a common base ( 5 );   characterized in that the height selection system ( 2 ) comprises:   a revolver ( 2   h ) comprising at least one groove ( 2   e ), a bore ( 2   g ) and optionally reference symbols ( 6 ) and at least one mobile space ( 2   x );   a screw ( 3 ) with its corresponding nut ( 4 );   a housing ( 2   f ) in at least one of the side walls ( 1   f ), with at least one projection ( 1   b ), a fixed space ( 2   a ), a hollow shaft ( 1   d ), wherein said housing ( 2   f ) houses the revolver ( 2   h ); and   at least one-foot ( 1   a ) projecting from one of the side walls ( 1   f ),   wherein the screw ( 3 ) passes through the hollow shaft ( 1   d ) and the bore ( 2   g ), screwing into the nut ( 4 ).   
     
     
         2 . The tray with height selection system ( 2 ) according to  claim 1 , characterized in that the screw ( 3 ) with its corresponding nut ( 4 ), the hollow shaft ( 1   d ) and the bore ( 2   g ), can be replaced by any other fastening means, which allows the revolver ( 2   h ) to rotate and be fixed within the housing ( 2   f ), such as rotating clips, bearings or rivets. 
     
     
         3 . The tray with height selection system ( 2 ) according to  claim 1 , characterized in that the foot ( 1   a ) is coupled in the fixed space ( 2   a ) of the revolver ( 2   h ), when a first tray ( 1 ) with the height selection system ( 2 ) is stacked on a second tray ( 1 ) with the height selecting system ( 2 ). 
     
     
         4 . The tray with height selection system ( 2 ) according to  claim 1 , characterized in that the foot ( 1   a ) projects from a side wall ( 1   f ) downwards, wherein said foot ( 1   a ) lies below the housing ( 2   f ), while at the top of the housing ( 2   f ), the fixed space ( 2   a ) is found. 
     
     
         5 . The tray with height selection system ( 2 ) according to  claim 1 , characterized in that, the foot optionally projects from the side wall ( 1   f ) upwards, thus the foot ( 1   a ) is located on the housing ( 2   f ), while the fixed space ( 2   a ) lies in the lower part of the housing ( 2   f ). 
     
     
         6 . The tray with height selection system ( 2 ) according to  claim 1 , characterized in that the revolver ( 2   h ) optionally have reference symbols ( 6 ) which indicate a predetermined height configuration, assisting the user to determinate the selected position of the revolver ( 2   h ) at the desired height. 
     
     
         7 . The tray with height selection system ( 2 ) according to  claim 1 , characterized in that the hollow shaft ( 1   d ) projects horizontally from the center of the housing ( 2   f ), while the protrusions ( 1   b ) of the housing ( 2   f ) project radially towards the center of the housing. 
     
     
         8 . The tray with height selection system ( 2 ) according to  claim 1 , characterized in that the projections ( 1   b ) can be fitted under pressure into the grooves ( 2   e ) of the revolver ( 2   h ), leaving a space between both pieces so that the revolver ( 2   h ) can rotate under pressure inside the housing ( 2   f ). 
     
     
         9 . The tray with height selection system ( 2 ) according to  claim 1 , characterized in that the hollows ( 1   g ) of the side walls ( 1   f ) can be replaced by any other means that allows manipulating the tray. 
     
     
         10 . A tray with height selection system ( 2 ) according to any of the preceding claims, characterized in that it forms a column or stack of nested trays. 
     
     
         11 . A tray with height selection system ( 2 ) according to any of the preceding claims, characterized in that it forms a column or stack of trays assembled accordingly by means of the fixed space ( 2   a ) and the foot ( 2 ).
