ABSTRACT:
Stopper removal apparatus of the type in which gas under pressure is directed into a container thereby to eject a cork or like stopper. The apparatus directs gas from a gas cylinder into a gas reservoir sealed by a piston valve. Each gas cylinder has its own seal to prevent gas escaping during storage. As a new cylinder is installed and the cylinder seal is broken, the resulting gas from the cylinder forces the piston valve to its sealing position, so no gas escapes. The gas pressure provides the sealing force. When an actuator moves the piston valve to an open position, gas passes through passages and a hollow needle that penetrates the stopper to exit within the container to eject the stopper.
A cover assembly completely encloses the needle. A disk at one end of the cover retracts as the needle is inserted into the stopper. After the stopper is ejected it remains on the needle within the cover. Tabs extending through the cover enable the disk to be returned to its original position thereby removing the stopper and enclosing the needle.
