A method for releasing residual pressurised fluid from an aerosol canister, said method comprising the manual opening of a vent assembly (614) for said canister (600), the vent assembly (614) comprising first (615) and second (616) members and a receiving part (617), the receiving part (617) having an outer surface configured to form a fluid seal against an edge of a hole in the canister (600), and an internal volume having a longitudinal axis, the second member (616) disposed within the internal volume of the receiving part (617) and configured for linear translation along the longitudinal axis relative to the receiving part (617), the first member (615) rotatably engaged with the second member (616), rotation of the first member (615) relative to the second member (616) configured to impart translation of the second member (616) along the longitudinal axis such that, in a first position, the second member (616) forms a fluid seal against the receiving part (617) and, in a second position, a fluid passage is formed between the second member (616) and an inner surface of the receiving part (617). |
