A transport and storage container for flowable materials has an outer enclosure formed with a gridwork of vertical and horizontal bars which surround a plastic inner vessel. A pallet is formed by a similar gridwork and the supporting feet are at least in part formed by downwardly bent portions of the grid bars of the bent pallet which are connected to extensions of the vertical bars of the outer enclosure, e.g. by welding. The supporting foot may be bent from these portions or may be constituted by an angle member welded thereto and a reinforoing plate or sheet can be welded to the downwardly bent portions for greater stability.

Why it's free to use
- Filed October 6, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 6, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 6, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
