Pairs of parallel slits in the sheet define canstabilizing strips. The sheet is clippable onto the cans in such manner that portions of the chimes extend into the paired slits and that each strip fits without, folding such strip, under portions of two adjacent cans. A package for merchandising such cans can be readily assembled by steps that include providing such cans in a rectangular array and clipping the sheet onto the cans in the specified manner.

Why it's free to use

  • Filed April 3, 1991 and granted January 14, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 3, 2011.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 3, 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.
