Abstract

A bottle cap for universal retrofitting to one of a number of pre-existing beverage containers containing a beverage and having a removed cap and threaded aperture, having at least one container portion for containing at least one dispensable material, a threaded portion for receiving the threaded aperture and creating, when threaded, a water-tight assembly; and a bag containing the dispensable material located in the container portion. Upon screwable attachment of the threaded aperture into the cap, the threaded aperture parses at least a portion of the bag to permit feeding of the material into the beverage. A plurality of such caps is also shown packaged for commercial sale. The material contained in the cap is selected from the group consisting of vitamins, medicaments, teas, flavors, concentrates and water-soluble food material. Also shown is a universal cap further having a moveable aperture assembly creating an open, fluid-flowing state and a closed, fluid-stopped state, having a top portion containing a drinking aperture and an elongated, moveable fluid-flowing portion. In accordance with another aspect of a dissolvable membrane encloses dispensable material in the cap, and the membrane dissolves upon contact with fluid in a fluid container to release the dispensable material into the fluid.

Claims

1. A bottle cap for universal retrofitting to a fluid container containing a fluid, comprising:

an enclosure forming a first chamber having a first opening;

threads on the enclosure for retrofittedly attaching the bottle cap to the fluid container;

a plastic door attached to the enclosure and covering the first opening, the plastic door being thicker in a first section and thinner in a second section; and

means in the enclosure for applying pressure on the plastic door when the bottle cap is attached to the fluid container.

2. The claim of claim 1, further comprising a liquid in the first chamber.

3. The claim of claim 1, further comprising a powder in the first chamber.

4. The claim of claim 1, wherein an intersection of the first section and the second section is a straight line.

5. The claim of claim 1, wherein the door is molded as part of the enclosure.

6. The claim of claim 1, wherein when the means for applying pressure contacts the door, the door is opened along the intersection of the first section and the second section.

7. The claim of claim 6, wherein the door remains attached to the enclosure.

8. A bottle cap for universal retrofitting to a fluid container containing a fluid, comprising:

an first structure having a cavity, threads for retrofittedly attaching the bottle cap to the fluid container and a plastic door, the plastic door being thicker in a first section and thinner in a second section; and

a second structure connected to the first structure, the second structure having means in the enclosure for applying pressure on the plastic door when the bottle cap is attached to the fluid container.

9. The claim of claim 8, wherein the second structure is connected to the first structure by mating threads.

10. The claim of claim 8, wherein the second structure is connected to the first structure by a friction fit.
