Capsule incorporating a doser and openable security cap, in particular for single-dose flagons

A capsule (3) incorporating a doser and an openable security cap, in particular for single-dose flagons, comprising:

• a lower part (4) inferiorly bearing a security strip (12) of known type, the capsule (3) bring provided with means for connecting which enable a removable insertion thereof on a neck (2) of a flagon (1);
• the capsule (3) including a reservoir (8), inserted sealedly in the neck (2) of the flagon (1), arranged internally of the lower part (4) of the capsule (3) and provided with a breakable bottom (8a);
• internally of which reservoir (8) a substance is contained, which substance is for inserting into the flagon (1) when the breakable bottom (8a) is ruptured;
• the capsule (3) also comprising a cutting element (9) for rupturing the breakable bottom (8a);
• the lower part (4) of the capsule (3) being superiorly open and is closed by an upper part (5) which is perimetrally connected to the lower part (4) by means of an easy-break ribbing (13);
• said means for connecting comprising a screw-coupling between the lower part (4) of the capsule (3) and the neck (2) of the flagon (1);
• characterized in that the capsule (3) comprises means for coupling, for making the reservoir (8) and the lower part (4) of the capsule (3) solid in upwards axial translation;
• the means for coupling comprising:
• an external ring (16), solidly constrained to the reservoir (8) and fashioned on an upper external part thereof, a section of which external ring (16) is hook-shaped with a hooked part thereof facing in a downwards direction;
• an internal annular projection (17), fashioned on an internal surface of the lower part (4) of the capsule (3), for inserting below the external ring (16) when the capsule (3) is screwed on the neck (2) of the flagon (1).
