Open the CIPO recordAbstract From the Canadian patent
A reusable bag for storing items. The bag has a band located over at least part of the bag's outer surface. The band is detachably secured to the bag with an adhesive. To reseal the bag after opening, the band is partially lifted away from the bag. A space is thus created between the band and the bag into which the twisted end of the bag may be inserted and secured. The band contains adhesive on only a center region of the band to permit the band to be easily separated from the bag and so that user contact with the band does leave adhesive on the user's fingers or wear adhesive from the band.

Why it's free to use
- Filed July 26, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 26, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 26, 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.
