ABSTRACT:
A metal dispensing container for contents under pressure comprising a neck portion with a diameter of over 22 mm and a cup-shaped valve portion. A clearance gap of at least 0.5 mm is left between the inside of the neck portion and the cup portion into which the neck portion is fitted following insertion of a seal. The outside of the cup-shaped portion is crimped over the neck portion so that deformation of the seal prevents leakage.
