ABSTRACT:
A can for housing and dispensing liquid or pasty masses under pressure, comprising a substantially dimensionally stable, pressure-tight outer container having an opening edge upon which there is sealingly secured a valve plate equipped with a dispensing valve. An at least partially deformable inner container includes a neck portion whose opening edge is sealingly secured at the valve plate or at the part of the dispensing valve protruding into the interior of the can. The neck portion of the inner container is dimensionally stable, but elastically deformable in radial direction and equipped beneath its opening edge with peripheral cams protruding radially from the neck portion and dimensioned such that the inner container, during introduction into the outer container, sealingly bears initially by means of these cams upon the opening edge of the outer container and only after overcoming a resistance dependent upon the shape of the cams and the elasticity of the neck portion is further insertable into the outer container.
