A rear wall of the container is hinged at its top and opens by gravity to discharge the bales from the container.

The rear wall may be opened and shut remotely, and a plurality of the containers may be readily nested with relation to each other for shipment.

Why it's free to use
- Filed May 21, 1991 and granted December 4, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 21, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 21, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
