Abstract
A device for removing a closure from a container includes a hollow needle, a piston for driving the needle into the closure and a compressed gas cartridge for driving the piston. Once the needle has been driven into the closure so that an end of the needle is inside the container, the piston can reciprocate to force air through the needle and pressurize the container in order to eject the closure. The piston can also reciprocate to evacuate air from the container through a stopper with a check valve when leftover contents of the container are to be preserved.
