Abstract
An invertible shipping container for shipping particulate material and including a shell forming a main portion of right quadrilateral cross-section and having a flat closed bottom, a pair of top mouths and a dual funnel portion joining the main portion to the pair of mouths and tapering towards the latter at relatively steep and distinct funnel angles to enhance tumbling instead of producing jamming by the bridging effect upon discharge of the material from both mouths of the inverted container. When the container is upright, one mouth of the container is used for filling while the other is used to suck out dust and air. A releasable cover closes each mouth and carrying devices are secured to the main portion to carry and tilt the container for emptying.
