drain opener tire of the receptacles (bottles) has a small neck openings with plugs cork or similar material with an automatic ejection of the plug after extraction

摘要

Instruments of the pneumatic opener type for opening essentially bottles corked with corks or other similar plug material by introducing a compressed gas through the cork by means of a needle (3). The cork is removed from the bottle by using differential flow rates of compressed gas and is automatically ejected from the needle. The opener may open bottles at a high rate without fatigue, without handling the bottles and without breaking the latter.
