Storage device with a shock proof closure for a stack of heavy coins

摘要

The transparent cylindrical body is manufactured from extruded polypropylene with a rigid base having a pronounced rim for stability. Its mouth is closed by a stopper moulded in one piece of low-density polyethylene with an external shoulder (17), a cylindrical or slightly divergent skirt (12) and a flexible domed base (11). The distance from the shoulder to the extremity (21) of the dome is at least equal to the distance between the open end of the container body and the top of the stack. The end (19) of the skirt has a diameter at least equal to that of the inside of the body.
