An inflation apparatus is described for a labeling machine for placing labels on containers. A sealing element seals the opening of a container whereby the sealing element covers the opening without substantial insertion of the sealing element into the opening in the container. A wall in the sealing element defines an opening through the sealing element for passing an inflation gas through the sealing element and into the container. A gas supply and conduit are provided for connecting the gas supply to the opening in the sealing element. The invention is particularly suited to in-line labeling machines.

Why it's free to use
- Filed April 21, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 21, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 21, 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.
