REFUELING PRESSURIZED CYLINDER WITH OUTFLOW VALVE Russian patent published in 2018 - IPC B65D83/42 

FIELD: package and storage.

SUBSTANCE: reservoir 31 is at pressure greater than 400 kPa at 20°C. Refueling outflow valve 20 comprises stem 6 with open at an axial end axial bore 24, the most distant from the reservoir 31, to provide the outlet opening, which discharges the composition in the axial direction. Stem 6 is movable from the closed position, to which it is displaced by the first resilient element with the spring force of more than 10 N, when the external force is not applied, to the discharge position against the first resilient element action to open the flow path from the reservoir to the outlet opening.

EFFECT: pressurized refueling cylinder 5 comprising reservoir 31 with the composition including the propellant and nicotine or its pharmaceutically acceptable derivative or its salt.
