Two stacking position square container

Abstract

A two stacking position square container is provided having an upper stacking position and a lower stacking position. The upper stacking position is provided by inserting a bottom of an identical body into a square opening to provide lateral stability and engaging supports on a bottom exterior profile with supports on a top interior profile. A lower stacking position is provided by inserting the bottom of the identical body into the square opening to provide lateral stability and engaging the supports on the bottom exterior profile with recesses on the top interior profile and the supports on the upper interior profile with recesses on the bottom interior profile. The body is symmetrical about both an x axis and a y axis. A 90 degree relative rotation about a z axis being used to change between the upper stacking position and the lower stacking position.

1 . A two stacking position square container, comprising: 
 a one piece integrally moulded body having a bottom with four side walls of equal length and height extending upwardly from the bottom to a define a square opening into an interior storage cavity, each of the four side walls having an exterior surface, an interior surface, a top peripheral edge and a bottom peripheral edge;    each of the four side walls having an intermittent top interior profile of supports and recesses along the top peripheral edge;    each of the four side walls having an intermittent bottom exterior profile of supports and recesses along the bottom peripheral edge;    an upper stacking position being provided by inserting a bottom of an identical body into the square opening to provide lateral stability and engaging the supports on the bottom exterior profile with the supports on the top interior profile;    a lower stacking position being provided by inserting the bottom of the identical body into the square opening to provide lateral stability and engaging the supports on the bottom exterior profile with the recesses on the top interior profile and the supports on the upper interior profile with the recesses on the bottom interior profile;    the body being symmetrical about both an x axis and a y axis with a 90 degree relative rotation about a z axis being used to change between the upper stacking position and the lower stacking position.    
   
   
       2 . The two stacking position square container as defined in  claim 1 , wherein a continuous planar top exterior profile is provided along the top peripheral edge.  
   
   
       3 . The two stacking position square container as defined in  claim 1 , wherein an engagement surface is spaced from the bottom peripheral edge of each of the side walls below the bottom exterior profile defining a peripheral engagement band around the body adjacent the bottom peripheral edge.  
   
   
       4 . A two stacking position square container, comprising: 
 a one piece integrally moulded body having a bottom with four side walls of equal length and height extending upwardly from the bottom to a define a square opening into an interior storage cavity, each of the four side walls having an exterior surface, an interior surface, a top peripheral edge and a bottom peripheral edge;    each of the four side walls having an intermittent top interior profile of support members separated by recesses along the top peripheral edge;    each of the four side walls having an intermittent bottom exterior profile of support members and recesses along the bottom peripheral edge;    a continuous planar top exterior profile along the top peripheral edge of each of the side walls;    an engagement surface spaced from the bottom peripheral edge of each of the side walls below the bottom exterior profile defining a peripheral engagement band around the body adjacent the bottom peripheral edge;    an upper stacking position being provided by inserting a bottom of an identical body into the square opening to provide lateral stability and engaging the support members on the bottom exterior profile with the support members on the top interior profile;    a lower stacking position being provided by inserting the bottom of the identical body into the square opening to provide lateral stability and engaging the support member on the bottom exterior profile with the recesses on the top interior profile and the support members on the upper interior profile with the recesses on the bottom interior profile;    the body being symmetrical about both an x axis and a y axis with a 90 degree relative rotation about a z axis being used to change between the upper stacking position and the lower stacking position;    stacking with an overlying single position container being effected by engaging a bottom of the single position container with the top exterior profile; and    stacking with an underlying single position container been effected by inserting the bottom into a top opening of the single position container until the engagement surface engages a peripheral edge of the single position container and the peripheral engagement band engages the top opening.
