As shown by the Figs. 7 and 8, the flange of the cap is provided with one or more tongues 50. As indicated previously, the sealing device comprises a sleeve with an annular groove having atapering side wall 48- and a tapering bottom portion 52.

v The bottom portion is provided with one orm'orere oesses53 corresponding to the number ottongues of the capand suitably disposed. The annular side wall 48 is provided withcorresponding projections 54 adapted and press on an opposed tongue oi' the cap. The upper part of the projection 54 is preferably b'eveled as at 55 joining at its upper'edge 56, the upper edge line 57 of the side wall 48 :hese projections 54 may be formed integralwith the side wall 48 of the groove or may be constituted by added parts 58 adequately secured to the sleeve. With said device, flange of thecap 'willbe compressed its peripheral extent, except where the tongues arelocated; these latter will receive a lateral compression from-the projections 54 so as to force them in the desired position against the flange of the cap. After the sealing operation the cap presents itself in a general form shown in ing of? one or morertongues will'release the sealing grip of the cap on the receptacle and permit the removal ofthe closure.
