Open-Topped Stackable Container

Abstract

An open topped stackable container tub ( 1 ) is provided comprising side walls ( 2 ), end walls ( 3 ) and a bottom wall ( 4 ), the side walls being provided with open fork lift insertion recesses ( 5 ) along the length of the side walls in proximity to the bottom. In a preferred embodiment the bottom is provided with downwardly protrusions ( 6, 7, 8 ) wherein outer dimensions of said protrusions mate with the inner periphery ( 9 ) of the open top of the container, allowing secured vertical stacking of two or more of said containers.

1 . An open topped stackable container comprising side walls, end walls and a bottom wall, the side walls being provided with open fork lift insertion recesses along the length of the side walls in proximity to the bottom, wherein upon stacking two containers one on top of each other, the upper container creates a substantially tight lid for the lower container. 
   
   
       2 . The container of  claim 1 , wherein said recesses create shoulders on the inner bottom of said container, along the Inner sides of said side walls, each of said shoulders having a shoulder side and a shoulder top surface  14 . 
   
   
       3 . The container of  claim 1  with a general rectangular shape seen from a top-view, with said side walls being longer than said end walls. 
   
   
       4 . The container of  claim 1  with a general rectangular shape seen from a top-view, with said side walls being shorter than said end walls. 
   
   
       5 . The container of  claim 1  with a general square shape seen from a top-view, with said side walls being essentially the same length as said end walls. 
   
   
       6 . The container of  claim 1 , the bottom of said container being provided with downwardly protrusions, wherein said downwardly protrusions are arranged such as to provide for fork slit slots under the container when said container is resting on a fiat surface, said slots being aligned with the side walls of the container. 
   
   
       7 . The container of  claim 1 , the bottom of said container being provided with downwardly protrusions, wherein said downwardly protrusions are arranged such as to provide for fork slit slots under the container when said container is resting on a flat surface, said slots being aligned with the end walls of the container. 
   
   
       8 . The container of  claim 6 , the bottom of said container being provided with downwardly protrusions, wherein outer dimensions of said protrusions mate with the inner periphery of the open top of the container, allowing secured vertical stacking of two or more of said containers. 
   
   
       9 . The container of  claim 1  having bevelled corner surfaces, the upper ends of which comprise outwardly extending corner pieces with handles/slits that can be used for lifting said container by hooks. 
   
   
       10 . The container of  claim 1  having at least one drain adjacent to the bottom wall for draining liquid from said container. 
   
   
       11 . The container of  claim 10 , wherein said at least one drain comprises a hole extending through said shoulder side. 
   
   
       12 . The container of  claim 10 , wherein said at least one drain comprises a hole extending through one of said end walls. 
   
   
       13 . The container of any of  claims 1  having an internal void volume in the range of about 250-660 L. 
   
   
       14 . The container of  claim 13  having a total height in the range of about 35-65 cm. 
   
   
       15 . The container of  claim 1 , produced from a polymer material comprising a polymer selected from polyethylene, including LLDPE, LDPE and HDPE, polypropylene, polyamide, polystyrene, polyurethane, polyvinylchloride, acetal, polyphenylene sulfide, polyester, acrylonitrile butadiene-styrene and mixtures thereof. 
   
   
       16 . The container of  claim 1 , comprising a single-walled container. 
   
   
       17 . The container of  claim 1 , comprising a double wall outer shell surrounding an inner core. 
   
   
       18 . The container of  claim 17 , wherein said Inner core comprises a material selected from polyethylene foam and polyurethane foam.
