Open the CIPO recordAbstract From the Canadian patent
A bag pack and a holder comprises a layered stack of flexible thermo-plastic bags having a folded over stiff header with oppositely projecting ears at its ends. The ears enter beneath flaps at opposite ends of a holder when bent rearwardly and inwardly. A central flap on the holder retains the header against forward pivotal movement as might dislodge the ears and the individual bags have exposed top openings when so arranged for successive removal from the pack. A second embodiment includes flaps on a holder entered between front and rear portions of a header for retention of the bag pack.

Why it's free to use
- Filed May 7, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 7, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 7, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
