Abstract
A plastic conical 55 gallon storage drum apparatus is disclosed. The drum includes a generally cylindrical hollow container having a top portion, a mid portion, and a lower portion. The top portion has an outer diameter which is larger than an outer diameter of the mid portion, and the lower portion wherein the top portion and the bottom portion form a cylindrical shape, and the mid portion forms a conical shape. An elastic flexible removable bumper belt can be located about the outer diameter of the lower portion of the drum. The belt has an outer diameter approximately the same as that of the outer diameter of the top portion of the container. Filled drums can then be stored side by side together during transportation and reducing the possibility that the drums will tilt and collapse during extreme lists of approximately 30 degrees or more. The belt itself can be removed and stored in the inside bottom of the drum when the contents of the drum have been emptied. Further, the conical shapes of the drums allows for the stacking of the drums when the drums have been emptied of their contents. The elastic belts can be preformed into a ring shape from resilient material such as rubber and the like, and stretched about the lower portion of the container. Alternatively, flexible loops can be incorporated to hold the belt in place. A still another embodiment includes interspersing flexible link portions together with inflexible portions to form the belt and using a latch fastener to connect the belt into a loop shape for attachment about the lower portion of the drum.
