Dispensing capsule
A dispensing capsule and venting system for dispensing materials into a container. The dispensing capsule has a capsule body with a sidewall having at least one vent, and a bottom wall which is partially detachably attached to the capsule body. A cap portion is provided that has a closed top end and a sidewall extending below the top end, the cap portion being placed in the capsule body to define a material containing cavity. An activation device is provide for partially separating the bottom wall from the capsule body. Vents are provided to insure no residual fluid collects within the dispensing capsule, that the user can fully extract all fluid of the from the holding container and that pressure can be equalized between the internal pressure of the bottle with the ambient outside pressure. A method of using the dispensing capsule is also provided.
This invention relates to a dispensing capsule that will hold material(s) such as liquids, dry ingredients, pastes, gels, etc. until these materials are dispensed into a container into which the capsule is engaged and then activated. For example, the dispensing capsule can be inserted into the neck, throat or opening of a bottle, jar, bag, etc. filled with another material, such as water, carbonated water, a solvent, a solution, beverages, foods, chemical solutions, and other materials contained or containable in the container. The material(s) stored in the dispensing capsule can then be rapidly dispensed into the container when desired and mixed into the contents of the container. Vents can be provided to insure the users ability to empty the fluid from the container, drain any residual fluid from the capsule and insure pressure equalization between the inside pressure of the container with ambient pressure outside the container. The dispensing capsule may be built integral with the existing bottle cap, the dispensing capsule may be pre-mounted in the container at the factory after the container itself is filled with material, and/or the dispensing capsule can be used with existing containers and inserted by a user. A conventional bottle or other container cap or closure can used to seal the container's contents, including the dispensing capsule, or a specialized cap design can be provided.
BACKGROUNDMany foods, beverages, nutritional supplements, nutraceuticals, drugs, cosmetics, and chemicals such as adhesives, polishes, cleansers, pesticides, dyes and other substances are often supplied in liquid, powder, paste or other form, and have active ingredients mixed with inactive ingredients, carriers and solvents. Often times, these mixtures (and/or their active ingredients) do not retain their flavor, appearance, stability, strength, effectiveness or other important properties for long periods of time after their various ingredients have been mixed together. For example, while sugar and other ingredients in beverages can remain stable and resist spoilage for very long periods of time, once mixed with water, flavorings, other ingredients, a much shorter shelf life typically begins. Certain compounds, like amino acids will remain fairly stable in a dry form, but once exposed to water, will quickly break down, thus giving some mixed solutions a relatively short shelf life. Indeed, the commonplace incompatibility after mixing of ingredients can mandate that certain products be used relatively soon after the mixing process to prevent deterioration, discoloration, interactions and the like.
It can also be important that admixtures of various ingredients be carried out in a clean and sterile environment and with careful measurement of the various components to guarantee that proper results are obtained. In many cases, it is beneficial to avoid contact with a user's hands to avoid possible contamination and also possible contact of the user's skin with the material. It is also important that attention be paid to preventing any residual fluid being left either in the capsule or the container to aid in the prevention of bacterial and mildew types of growth.
The use of conventional liquid containers such as glass and plastic bottles for carrying water, punches, juice mixes, milk, formulas, hydrating formulas, power drinks and other beverages is well-known. There are numerous active and non-active substances including activated oxygen, vitamins, minerals, amino acids, herbs, nutrients, colorants and flavorants that would be desirable to add to liquids such as water, milk, juices or other beverages to give the consumer added benefits, particularly those useful for the health of the consumer. Many of these substances, however, have short shelf lives, discolor, interact or degrade quickly when combined with liquids or other substances. Therefore, many beverages are currently sold either without the added beneficial ingredients, or have otherwise shortened shelf lives.
It is known in the art to provide dispensers containing a concentrate of soluble materials to a fixed quantity of solute, usually water, for dispensing. Thus, the prior art teaches containers for beverages wherein the interior of the container is divided into a compartment having a basic ingredient (e.g., a diluent) and a compartment which can be ruptured so as to mix, within the container, the basic ingredient and some form of a modifier. This style of container permits for mixing action at the time of consumption since prior mixing would be less desirable.
It is also known to provide a dispensing capsule that fits into the mouth of a bottle, which dispensing capsule can be activated to dispense the materials into the bottle. However, prior designs can have problems in that they do not provide for adequate drainage of liquid out of the dispensing capsule and in many cases leave mixed fluid trapped in the container. In both cases the net result is the accumulation of a small reservoir of fluid, which is susceptible to bacterial growth and mildew.
It would be desirable to have a dispensing capsule that could be conveniently activated and used with a container with or without removal, and in a highly sanitary manner by allowing the user to operate the capsule through a mechanical means without requiring the user to actually touch the capsule and or allowing for the removal of the capsule without the user having to pull the capsule out of the bottle by hand.

The dispensing capsule can be conveniently be made from materials such as plastics. Also, while the bottom walls in the embodiment are shown as being partially frangibly attached to the dispensing body, other detachable attachment mechanisms, such as mechanical connections, can be used.
While a threaded cap is shown in the embodiments of
Although the embodiments depict the dispensing capsule attached to a bottle, the container can comprise jars, wide mouth bottles, containers with apertures, hard and soft plastic containers and bags (e.g. for containing solutions, such as medical solutions for drip infusion, etc.), cans, or other containers.
With regards to all of the above described embodiments that include vents, the vents will permit venting and pressure equalization between the contents of the bottle (or other container) and the outside atmosphere. If one simply squeezes a bottle of water on hot day it becomes readily recognizable that the internal pressure inside the bottle leaves very little room for displacement. In the case of dispensing capsule without vents, it can be difficult to activate the dispensing capsule by pushing down on a cap since there can be substantial back pressure in the can which will prevent this from occurring. On the other hand, if a vent is provided, this will help relieve back pressure by permitting pressure in the container to equalize with the ambient pressure before the dispensing capsule is activated.
As explained above, the vents can further permit a user to drink liquid either liquid that is unmixed with the material in the dispensing capsule, or liquid with the material mixed in, in either case without having to remove the dispensing capsule beforehand. This can be very convenient because it gives a user a choice of drink fluid with, or without the material mixed in. For example, a user may start out with pure water, and later decide to mix in the material, or mix the material in from the beginning, and then later use the bottle with plain water. In addition, the vents allow the user to extract all the fluid material in the container which otherwise would be trapped by virtue of the capsule blocking its exit in a similar manner to a standpipe trapping fluid within a reservoir.
Now that embodiments of the dispensing capsules have been described, some of the methods of use of the device are described.
