A flexible pouch, filled with a flowable product has a front pouch wall (22) joined to a rear pouch wall (23) along opposite side edges and along a bottom (32) edge. The front pouch wall, when flat has a first width at a first level , (L1) above the bottom edge and concave or oblique opposite sides (246 266) , between the first level and the bottom edge so that a width of the front pouch wall progressively decreases below the first level at least down to a second , level (L2). In consequence when the pouch is set down with the bottom edge on a flat surface, the sides between the first level and the bottom edge collapse to provide a stable basal platform for the pouch.

Why it's free to use
- Filed August 26, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 26, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 26, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
