Bottle cap with selectable additives
First Claim
1. A cap for a bottle with an opening, the cap comprising:
- (a) a base having an axis, a top surface, a bottom surface, a cavity in the bottom surface designed to attach to the bottle opening, and an aperture extending from the top surface to the cavity;
(b) a housing mounted to the base so as to rotate about and reciprocate on the axis and having a bottom surface, and an operative surface, the housing having a plurality of compartments and at least one vacant location arranged in a circle around the axis inside the housing, each compartment having an opening in the operative surface covered by a frangible seal, at least one of the compartments containing an additive, the at least one vacant location not containing an additive;
(c) at least one spike extending toward the operative surface from the aperture;
(d) the housing rotatable on the axis such that the compartment openings and the at least one vacant location can align with the aperture;
(e) the housing reciprocating on the axis between a selecting position wherein the housing operative surface is pulled away from the base top surface and the frangible seal associated with a compartment aligned with the aperture is intact, and an operative position wherein the housing is pushed toward the base and the at least one spike pierces the frangible seal associated with the compartment aligned with the aperture, thereby allowing the additive to flow downwardly into the aperture and into the cavity.

Abstract
A cap for bottles that allows a user to select additives. A base has an axis with a coaxial cavity, typically threaded, for attachment to the bottle. A housing rotates and reciprocates on the axis between a selecting position where the housing and base are pulled apart and an operative position where the housing and base are pushed together. Compartments with additives and one or more vacant locations are arranged in a circle around the axis inside the housing. An opening in the compartment bottom is covered by a frangible seal. As the housing rotates, the compartment openings or vacant location align with an aperture in the base that extends into the cavity. Spikes extending from the aperture puncture the compartment opening seal when the housing is pushed to the operative position, allowing the additive to flow into the bottle. The vacant locations provide positions for storage and transportation.
