Abstract From the Canadian patent

A drainable ostomy pouch (10) has an outlet (22). Reinforcing members (32 34) at the outlet (22) are deformable by application of manual pressure at their ends to distend the outlet (22). The lateral edges of the reinforcing members (32 34) may be offset, which encourages the reinforcing members to consistently bend away from each other. A peelable distributed mechanical engagement fastener (46) secures the outlet (22) in a folded condition. The fastener parts (46a and 46b) are hook- hook type plastic extrusions and provide a snap-engagement. A security flap (50) is foldable under the outlet (22) when in its folded condition. The outlet is released in two stages.

Why it's free to use

  • Filed June 30, 2003 and granted September 10, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 30, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 30, 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.
