Date Mar. 20, 1997Device (1) for sealing a closed container (2) comprising a neck (3), the opening (3a) of which is plugged, and provided with an external annular lip (3b), the device firstly comprising an internal cap (5) for fitting coaxially over the neck (3) of the plugged container (2), comprising catching teeth (6) distributed angularly about the axis (7) of the cap, each teeth having a radially outwards elasticity starting from a position (FIG. 3) of snap-fastening under the annular lip (3b), secondly, means (9) of access, which are arranged on the cap (5), and thirdly, an external sleeve (10) for sliding coaxially against and on the outside of the catching teeth (6), including a circumferentially continuous band (10a) provided along one of its edges with an internal annular ridge which may be continuous or discontinuous, for snap-fastening under the rim (6a), when the said sleeve (10) is in the fitted position. The band is radially elastic so that it can be fitted onto the cap when the annular ridge (11) is in the snap-fastened position, but strong so as to be indivisible, unless the said sleeve (10) is permanently destroyed.</p> |
