Abstract (en)
A sealing mechanism for a vessel (2; 20) which has an opening portion (3) closable by a cap (1) said cap (1) having a plug portion (4) and a seal plug (5); the plug portion (4) having an end wall (11) for covering the opening portion (3) of said vessel (2), a side wall (12), and a cylindrical wall (15) projecting generally axially from the end wall (11); the side wall (12) having an inner circumferential surface arranged to engage an outer circumferential surface of the opening portion (3) ; the cylindrical wall (15) being positioned inwardly of the side wall (12), and forming a receiving chamber (14), the receiving chamber having an opening (13) at its end remote from the end wall (11); the seal plug (5) being removably attachable to the cylindrical wall so as to close the receiving chamber opening (13), and having an outer circumferential portion (16) arranged, in use, to project beyond the outer circumference of the cylindrical wall (15); wherein the opening portion (3) of said vessel (2; 20) is provided with an inwardly protruding portion (22), which is so dimensioned and arranged that the outer circumferential portion (16) of the seal plug (5) may pass the protruding portion (22) when the cap (1) is applied to the vessel (2; 20), but may not pass the protruding portion (22) when the cap (1) is removed, thereby causing removal of the seal plug (5) from the receiving chamber (14). <IMAGE>
