FIELD: hand- or power-operated devices for opening closed containers, particularly to remove sealing means made of resilient plastic elastomeric material from neck of bottle or another glass container.
SUBSTANCE: device comprises nozzle to direct compressed air flow and to provide predetermined compressed air flow velocity and nozzle orienting post. Sealing means is removed from bottle under the action of pressure drop in compressed air jet due to aerodynamic effect of compressed air flow constriction in the jet, which is caused by neck streamlining with air flow or by presence of corresponding convex surface opposite to sealing means.
EFFECT: improved sterility and increased operational simplicity.
