摘要

The invention describes a bottle cap in which a detachable section (9) can be ruptured from the remainder of the cap using a common tool such as, for example, a hex key. A frangible seal (13), recessed below the upper surface (6) of the cap, connects the detachable section to the remainder of the cap and thus, when the detachable section is withdrawn, the risk of spillage is minimized.
