Patent number: 7837037Abstract: 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.Type: GrantFiled: December 20, 2006Date of Patent: November 23, 2010Assignee: Drader Manufacturing Industries Ltd.Inventors: Gordon McTavish, Cory Koski, Hongqiao Li

Patent number: 7699172Abstract: A two position stacking delivery tray is provided which is capable of stacking with itself, and also stacking with existing single position stacking delivery trays. A single uneven upstanding tongue is positioned along a top edge of each of a first side wall and a second side wall. The uneven upstanding tongue defines a first engagement with peaks and valleys. Tongue receivers are positioned in the bottom defining an uneven groove adapted to mate with a single upstanding tongue of an underlying tray having a single stacking product height position. The uneven groove defines a second engagement with peaks and valleys. The peaks and valleys of the first engagement and the second engagement are asymmetrically positioned, so as to provide two stacking product height positions by relative rotation of stacking trays by 180 degrees.Type: GrantFiled: February 22, 2006Date of Patent: April 20, 2010Assignee: Drader Manufacturing Industries Ltd.Inventors: Gordon McTavish, Cory Koski, Hongqiao Li
