  • Sipper tube insertion and removal apparatus
    Patent number: 5852861
    Abstract: A sipper tube insertion and removal apparatus is provided for easily and consistently inserting a sipper tube into a stopper with a hole and for also easily and consistently removing a sipper tube from a hole in a stopper. For insertion of a sipper tube into the hole of a stopper, the apparatus includes a sipper tube insertion head for holding the sipper tube, a stopper insertion platform for holding the stopper, and an actuator. The stopper insertion platform holds the stopper such that the hole of the stopper is aligned with the sipper tube, and the platform is disposed at a predetermined distance apart from the sipper tube insertion head. The actuator closes the predetermined distance between the sipper tube insertion head and the stopper insertion platform so as to cause the sipper tube to be inserted into the hole of the stopper.
