One gas cork ejector invention that may not be

easily recognized in its manufactured form is French

Patent 1,502,172 issued October 9, 1967. Lying in a

drawer, all one would see is what appears to be a

two-part tube with a lever attached. The protective

cover for the needle actually retracts into the upper

body when in use so the needle is never exposed.

The assembly is placed over the cork and the top is

pushed down. The spring-loaded sleeve slides up and

the needle enters the cork. Once fully inserted, the

assembly is rotated and a knife edge at the bottom

of the top assembly cuts the foil. Pushing the lever

injects gas into the bottle and the cork is lifted. The

cork is removed from the needle and the cover

springs back into place.

In 1965 Marius Triverio had made application for a

patent on a cork ejector and the idea was further

refined by his wife Yvonne Thérèse Perrolaz and

sister Viviane Alice Émile Triverio, (married to

Glemet). The two women had applied for their patent on November 7, 1966. Models

supplied in boxes labeled Tir Bouchon MT are from Marius Triverio (MT). The lettering

SARL on the box means "
