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.

Each of these disclosures are herein fully incorporated by reference.BACKGOUND 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, fla...

AI Technical Summary

Benefits of technology

[0005] It is important to maintain freshness of fluid-based products. This is particularly important when the material to be dispensed is vitamin-based, since it is known that water-miscible vitamins can lose their potency over time when in a fluid environment, through changes in, inter alia, temperature, pressure, and light. 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.

[0009] It is a further object of the instant invention to provide a universal cap in a plurality of different flavors for single-use attachment to pre-existing fluid containers, for simple access by a consumer.

[0017] In other embodiments, the dispensable material is located in a sealed bag or packet formed of a parseable membrane material. The bag or packet is located in an upper portion of the cap, positioned across the cap. Upon screwable attachment of the threaded aperture into the screwable attachment means, the threaded aperture parses at least a portion of the bag or packet to permit feeding of the material into the fluid. Once parsed, the material freely flows into the fluid, either through gravitational action, shaking, or a combination thereof. Once fed into the beverage, the material disburses, creating a fresh product. The bag can be mounted to the cap via any suitable means, such as adhesive or a plastic support ring. Because the bag is sealed and self-contained, there is no need to seal the bag in an airtight manner across the cap. Thus, even if some of the adhesive comes loose, the dispensable material is still securely stored within the bag until it is released by the user. The bag or packet is preferably perforated in the areas that are to be opened, to ease the opening of the bag by the user.

[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.
