On the 25th July 2012 the Intellectual Property Office granted a patent for the amazing invention of the manual sealing tin can. It is 5 years since inventor Guy Grumbridge hit on the idea of sealing a can with a simple but ingenious push-on closure.

In the past cans have all been closed with a cumbersome and expensive seaming machine that literally spun the can and bent the closing end over the tin to form the conventional tin can end. At last, this can now be done by hand in one simple movement.

Owners of the patent, Tinware Direct Limited, have been in business for 12 years and are poised to make big profits from Grumbridge’s invention. “The lack of can closing machinery meant that most companies were unable to use tin cans for packaging their products, now any one can seal a tin – no skill, no machines, no bother” said Tinware’s MD Guy Grumbridge.

The product is available for filling with dry products. Tinware Direct is currently developing a version that will be suitable for liquid and pressurised filling.
