DETAILED DESCRIPTION

(6) FIG. 1 is a front perspective view of one aspect of the dispensing capsule of the present invention in an exploded view. The dispensing capsule 1 comprises a cap body 2, a bulbous actuator 3, a sealing member 4, and a cover 5. In some embodiments, cap body 2 is a generally cylindrical ring or annulus-shaped element although other shapes and configurations are contemplated such as squares, polygons, and the like. Cap body 2 includes internal threads 22 and an outer gripping surface 21. Internal threads 22 are configured to engage a threaded top or spout of a target or secondary container 6 (FIG. 3) as further described herein. Cap body 2 further includes at its top portion a lip 23 which includes an outer circumferential groove 24. The groove 24 is coaxial with respect to the cap body 2. Bulbous actuator 3 is flexible and has a generally hemi-spherical actuator button 31. The actuator 3 includes a perimeter lip 32 around the bottom portion of the button 31. The perimeter lip 32 includes an annular protrusion 33 extending upward therefrom. Cover 5 is generally cylindrical or conical and includes a lower edge 51. Cover 5 is configured to be received over the bulbous actuator 3 and removably attached to the cap body 2. In some embodiments, lower edge 51 is received in groove 24 of the cap body 2. In other embodiments, cover 5 is semi-permanently attached to the cap body 2 by a line of weakening material or other removable and/or frangible element.

(7) With reference to FIGS. 2-3, actuator 3 is received underneath cap body 2 such that perimeter lip 32 engages lip 23 of the cap body 2. More specifically, as shown in close-up FIG. 3A, actuator 3 is received underneath lip 23 of cap body 2 such that annular protrusion 33 is received in annular groove 25 on the underside of the lip 23 of cap body 2. This creates a tight fitment between the actuator 3 and the cap body 2 in order to prevent the actuator 3 from detaching from the cap body 2 during actuation as further described herein. The sealing member 4 is disposed inside of the cap body 2, and in some embodiments is attached underneath across the bottom of the actuator 3. In some embodiments, the sealing member 4 is attached to the underside of the perimeter lip 32 by a heat seal, adhesive or other means. As such, the perimeter lip 32 of the actuator 3 is disposed between the lip 23 of the cap body 2 and the sealing member 4. In an assembled state, the actuator 3 and sealing member 4 are both define a storage chamber that is configured to contain a first ingredient 3a.

(8) FIGS. 3-4 show the capsule 1 of the present invention attached to a secondary container 6. As shown, cap body 2 is threadingly engaged to container 6 by way of threads 22. Container 6 may also contain a second ingredient 6a with which the ingredient 3a in the chamber of the capsule 1 is mixed. Here, cover 5 is removed from the top of the cap body 2 and is not shown. The sealing member 4 is intact as the capsule 1 is shown in its pre-activation state. To activate the capsule 1, the user applies manual pressure to the top of actuator 3. This force causes the relatively flexible actuator 3 to deform inward and the chamber therefore compresses somewhat causing a pressure build up inside chamber. The pressure build up is such that it is sufficient to cause sealing member 4 to rupture therefore dispensing first ingredient 3a downward and into container 6. At that point, first ingredient 3a can mix with second ingredient 6a, capsule 1 can be removed from container 6 and the now-mixed ingredients can be accessed. In some embodiments, a line of weakening may be present on sealing member 4 to facilitate rupture of sealing member 4 when pressure is applied to the actuator 3. In some embodiments, the bulbous actuator 3 is configured to resilient rebound to its initial position after activation. This promotes complete expellation of the ingredients in the chamber and enhances overall usability. Moreover, the tight fitment between the bulbous actuator 3 and the cap body 2, by way of the groove and protrusion engagement, assures that the actuator 3 will not dislodge from the cap body 2 during or after actuation of the capsule 1.

(9) It is appreciated that the capsule of the present invention can comprise any combination of materials including plastics, rubbers, aluminum, resins, and the like. Further, the capsule 1 may also be sized and shaped to accommodate fitment on any desired container such as bottles, IV bags, pouches, and the like. Furthermore, the threaded engagement with the container may be substituted for various snap-on or other releasable fitments known in the art.

(10) The bulbous actuator 3 may comprise a variety of materials provided such material is sufficiently durable and elastic so as to have a rebounding effect after dispensing of the ingredients from the internal chamber of the capsule 1. Accordingly, in some embodiments, bulbous actuator 3 comprises a thermoplastic polyurethane (TPU) material that can be presented in a variety of colors, shapes, and sizes without departing from the functionality of the invention described herein. It is further appreciated that the sealing member 4 may comprise a variety of plastic and foil-like materials. In some embodiments, the sealing member 4 comprises a thin plastic or resin material having one or more lines of weakening to allow for easier selective dispensing of the chamber ingredients 3a. In other embodiments, the sealing member 4 may comprise a foil or paper material equally suitable to be broken by the action described above.

(11) The chamber of the capsule can contain any liquid, powder and or gas and or micro/nano encapsulation in any combination desired. The dispensing capsule 1 can be mounted or applied at any location of a container including a bottle, pouch, can, IV bag, drum or tote. In some embodiments, the capsule is suited to be received on the threaded opening of such containers in order to provide a leak-free fitment. The chamber of the dispensing capsule stores any desired ingredient and may be dimensioned as desired to fit a variety of applications. The size and shape of the capsule of the present invention should not be construed as limited to the sizes and shapes shown in the drawings herein. Rather, the volume of the chamber 6 and the diameter of the various components can vary as desired and/or can vary depending on the size and shape of the intended container or other parameters. Further, the chamber need not be filled completely, but rather can accept any volume of an ingredient desired depending on mixing parameters and the desired final product.

(12) By way of example only, the device can be used for drinks, hair care, pet products, drugs, over the counter medications, cleaning products, soups, dressings, nitrogen, fuels and engine cleansing, oils, waxes, pH enhancers, oral care, oxygen, adhesives and other categories of use depending on the ingredients and formulas. Also a coating of any type of moisture absorbent can be applied to the inside of the chamber to act as a desiccant and allow for moisture absorption of any excess moisture that may be contained inside the invention when filled and sealed.

(13) This dispensing capsule 1 can be molded in one or two pieces thus eliminating a high cost to manufacture other dispensing caps that are multiple pieces and difficult to fill and seal the ingredients desired. Furthermore, due to the encapsulated capsule excluding the sealing area the invention allows the ingredients to remain moisture free and have an unusually long shelf life and allowing with the sealed chamber to combine liquids and powders and oils and other ingredients to be sealed and stored separately if desired to prevent any reaction with one another. Also the device can include multiple applicators such as drinking spouts, pouring spouts and removable dosing cap for use of a product that has flow through to allow dispersing of all ingredients into a desired container. The exact configuration of such spouts and applications is not limited only to those designs shown in figures herein.

(14) The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
