  • Bottle for preserving in a separated condition substances to be mixed together before dispensing
    Patent number: 5542528
    Abstract: The bottle (1) comprises a body (5) closed by a capsule (8). Within the capsule (8) there is a separator element (9) which closes its concavity to prevent mixing of the substances contained in the capsule (8) and in the body (5) respectively. To mix the substances the separator element (9) is removed by deforming the capsule (8).To prevent the bottle (1) being able to be opened without mixing of the substances having taken place, the outer surface (15) of the capsule (8) and the inner surface (6) of the container mouth (4) carry respectively an annular projection (14) and an undercut ledge (7) which mutually engage only by the effect of the radial expansion of the capsule (8) when the separator (9) is closed.
