Universal bottle cap having a dissolvable membrane

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.

No. 11 / 135,734 filed on May 24, 2005, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 943,712, filed on Sep. 17, 2004, now U.S. Pat. No. 6,962,254, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 463,927, filed on Jun. 18, 2003, now U.S. Pat. No. 6,820,740. Each of these disclosures are herein fully incorporated by reference.BACKGROUND OF THE INVENTION [0002] The present invention relates to the field of beverages, dispensing materials into a container containing a fluid, and more specifically to beverages and fluids contained in bottles with removal caps, such that a cap can be retrofittedly placed upon the bottle or container, post removal of its originating cap, in a manner that dispenses materials including, e.g., vitamins, flavors and other ingredients, into the beverage or fluid.

Benefits of technology

[0021] There is preferably a removable cap or collar placed over or around the moveable aperture assembly, to prevent premature depression of the aperture assembly during shipping and storage.

Problems solved by technology

In these embodiments, the consumer is required to modulate the quantities, and mistakes result in under- or over-flavored mixtures.

In addition, fluid-based products can interact with plastic bottles, causing an unpleasant taste and comprising the health of the user.

Glass bottles are thus required, which are more expensive and much heavier.

The result can be shaken and the completed product created moments before consumption or usage.

These devices, however, incorporate convoluted mechanisms that do not permit retrofitting to pre-existing bottle designs, and rather have cumbersome mechanisms for rotation and dispensation.
