New canning process

Brazilians patented a new method of canning food products that does not require a can opener. The can has a removable lid, which is held in place by the vacuum in the can. The lid has a silicone-like dot seal on top, which covers a little hole.
Once you remove the dot seal the vacuum is broken and the lid slips right off. The dot seal is easily removed, with a little persistence you can remove it with your finger nail. It's a very clever system. (pics from my phone, sorry about the quality)
