able engagement to a container, said cap-being in 50
the form of a cylindrical shell having-‘container
engagement means at one end and an annular
outwardly extending ?ange at its opposite end
terminating in an upstanding wall, an inner shell _
having a depending spout tube, and intermediate ‘
annular shoulder, a cylindrical portion to ?t, the
inner wall of the closure cap and an outwardly
disposed annular ?ange adapted to be superim

minating in van upstanding wall, an inner shell
10 comprising a depending spout tube merging at
its upper end into a stepped annular seat, an
intermediate annular shoulder immediately above
said seat, a cylindrical portion to fit the inner wall
of the closure cap and an outwardly disposed an
15 nular ?ange adapted to be superimposed on said
3
cap'?ange, a gasket member seated against said
intermediate shoulder, a bulbous shaped ?exible
diaphragm having an apical inwardly projecting
integral knob and terminating its open end with
an outwardly ?aring ribbed annulus, said annulus
being disposed upon said inner shell annular
?ange and having a hermetic seal therewith by
reason of having the upper part of said upstand
ing Wall formed tightly about said ribbed annulus,
and a coiled spring member disposed between said
stepped annular seat and said diaphragm and.
