  • Patent number: 4590821
    Abstract: A stopper removing device mountable on a bottle. A carriage on the frame of the remover has a removing lip disposed beneath the head of the stopper. Upon downward movement of the levers, the carriage is driven upwardly to extract the stopper S. The levers have handles which are disposed approximately horizontally just after application of the stopper removing device to the neck of a bottle, such handles being gripped and forced downwardly to effect upward movement of the carriage and the stopper relative to the bottle. The levers have open slots slidably engaging studs on the carriage. The carriage has three sets of slides alternately engaging the opposite sides of a frame to mount the carriage in place. A shield is carried by the carriage and disposed above the head of the stopper to prevent the stopper, under gaseous pressure from the interior of the bottle, from being popped upwardly clear of the removing device and into the face of the user.
