or recessed portion l5, its inside diameter being
such as to closely ?t the neck ll of the bottle

the mouth and the inner wall of the bead and a
welded seam l‘l joining the lower end of said
tube with the outer wall of the bottle. This 15

metal sleeve having a tapping tool receiving part
and preferably also a cap anchoring means is
secured to said body in a ?uid tight manner,
