Abstract: A substance container has a cap that defines a cap space for an additive. The cap has a cap space opening closed by a seal which may or may not be pre-weakened, and a flexible press top having a pushing mechanism that reaches through the cap space attached on one end to the flexible top, while another end of the pushing mechanism is directed to the opening. The flexible press top has an upper side and an opposite lower side arranged such that upon depression the pushing mechanisms hold fixed radial positions during translation to the opening, contact with the seal and push through the seal.

Abstract: A cap construction for a container, having a storage space for dispersing a product into the container, a screw cap with a foil for closing the storage space, a support structure which is embodied for on the one hand by means of mutual screw-thread coupling same in a rotatable manner with the screw cap and, on the other hand, coupling the cap construction with the container and which is provided with a cutting element for cutting the foil. The cap construction has cutting element cuts through the foil upon rotating the screw cap with respect to the support structure, with the proviso that the support structure comprises a stop means for collecting the foil that was cut by the cutting element.

Abstract: 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.

Abstract: Caps for bottles with the box for powder material for preparation of beverages is the cap by which the basic box with the basic substance is closed, as e.g. drinking water and which contains the other box with the other liquid or powder substance shown in FIG. 1. It consists of the box (1) closed on the bottom-side with the aluminium foil (8) and slant damper (9) and on the upper side by the cover (2). The damper (9) that may be twisted round the hinge (O) and which have on the upper surface the one-arm vertical flexible lever (11) is arranged above the aluminium foil (18). The cover (2) has on the internal plane of the bottom tangs (13) and (14), as well as the barrier (17) by which during winding up and winding off it acts on the lever (11). By winding off the cover (2) the free end of the lever (11) is elastically bended, creating in it the moment of force, which twists the damper (9) which breaks through and removes the aluminium foil (8).
