ABSTRACT:
The package is formed of a casing (1) and a closure cap (6). A guarantee ring (7) is connected to the closure plug (6) via tear webs (8). The casing comprises an annular bead (3) beyond which is pressed the guarantee ring (7). A cap-like part (21) of the closure plug (6) has an inwardly protruding annular rim (12). The distance (b) of this annular rim (12) from the bottom of the closure plug is greater than the distance (a) of the annular bead from the edge (2) of the casing. Thus, the guarantee ring (7) as well as the inwardly protruding annular rim (12) can be pressed beyond the annular bead (3). On opening the closure plug, the guarantee ring (7) is torn off the closure plug, but, when again closing the closure plug (6), the closure plug (6) is secured in its closed position by the inwardly protruding annular rim, the inner diameter (13) of which is greater than the inner diameter (9) of the guarantee ring (7).
