the years ‘60 appeared the first cork ejectors.
idea, apparently original, was to extract the cork from the bottle by
injecting gas between the cork and the liquid.
realize that operation, a hollow needle longer than the cork had to
be pierced through.
operation was delicate because some corks are very hard and long, and
the effort to drive the needle through the cork is very important …
you then take the risk to destabilize the bottle, or even to break the
needle and seriously injure yourself.
it can be worst, because the most injuries happened at the time the
gas was injected. As a matter of fact, the bottlenecks were not studied
to resist to such a pressure and could explode at any moment and hurt
the operator or the guests.
pressure between the liquid and the cork must be very high to remove
the cork from the bottleneck.
ejectors can be classified into two categories: Gas ejectors (by inserting
a cartridge with neutral gas into the corkscrew) and the pump ejectors,
which are based on the principle of a bicycle pump. It is the operator
who injects air between the wine and the cork by doing a backward and
forward motion action on the handle.
years ’70 the popularity of cork ejectors rapidly decreased to
a point that they almost disappeared.
“Corky”, realized in Switzerland in 1964, is probably one
of the most popular models ever realised and copies of this specimen
are still produced nowadays (see picture).
