Caps for bottles with a box of powder material for preparation of beverages. The cap is applied to a basic box with a basic substance enclosed, as e.g. drinking water. The cap contains the other box with the other liquid or powder substance. The box is closed on the bottom-side with aluminum foil and a slant damper and on an upper side by a cover. The damper may be twisted around a hinge and have on an upper surface a one-arm vertical flexible lever arranged above the aluminum foil. The cover has on an internal plane bottom tangs, as well as a barrier, by which during winding up and winding off the cover acts on the lever. By winding off the cover a free end of the lever is elastically bent, creating in it a moment of force, which twists the damper and breaks through and removes the aluminum foil. Upon finishing mixing substances, the blend may be drank through the opening of the box. |
