DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0065] The following description sets forth various examples along with specific details to provide a thorough understanding of claimed subject matter. It will be understood by those skilled in the art, however, that claimed subject matter may be practiced without one or more of the specific details disclosed herein. Further, in some circumstances, well-known methods, procedures, systems, components and/or circuits have not been described in detail in order to avoid unnecessarily obscuring claimed subject matter. In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.

[0066] A perspective top view of the funnel container 10 of the present invention is shown in FIG. 1, with FIG. 2 showing a perspective bottom view of the same. In general terms, the funnel container 10 may include a funnel-shaped body 40, a removable bottom plug 20, and a removable top cover 70.

[0067] An exploded perspective top view of the funnel container 10 is seen in FIG. 3, with FIG. 4 showing a corresponding perspective bottom view of the same. FIGS. 5 and 6 show cross-sectional views of the funnel container 10 as assembled and with all parts separated in an exploded view. The funnel-shaped body 40 of the funnel container 10 has a shape best seen in FIG. 6, which extends from a wider top opening 44 to a narrow bottom opening 50. The shape of the funnel portion of the funnel-shaped body 40 may be selected to have a tangential line drawn to any point along its curved periphery to be not less than about 30 degrees to the horizontal plane, so as to facilitate easy removal of the content of the funnel container 10 therefrom during use.

[0068] The top opening 44 may have an external thread 46 configured to cooperate with an internal thread 78 of the top cover 70 to allow the top cover 70 to removably engage with the top opening 44 of the funnel-shaped body 40. A peripheral lip 43 may be provided to form a stop restraining the extent of the top cover 70 engagement with the top opening 44. Once the top cover 70 is assembled with the funnel-shaped container 40, the top edge of the top opening 44 may abut against the internal surface of the top cover 70, while the outer edge of the side wall 71 may abut the peripheral lip 43see FIG. 5.

[0069] An optional side tab 42 may be formed as a single unit with the funnel-shaped body 40 and extend sideways from the lip 43, as seen in FIG. 3. The side tab 42 may have an opening 41 formed therein and sized to accept a deformable central protrusion 22 of the bottom plug 20 as explained in greater detail below. In other embodiments, the side tab 42 may be omitted altogether, or, in further alternative embodiments, it can be made as a separate ring positioned over and engaged with the corresponding portion of the external surface of the funnel-shaped body 40, as the invention is not limited in this regard.

[0070] One or more depressions 73 may be formed in the top cover 70, including a bottom 76, and one or more protrusions 74 extending inward the depression 73 and spaced evenly along the periphery thereof. The depression 73 may, therefore, be shaped as a twist-lock receptacle 72 for accepting a corresponding twist-lock nozzle 52 of the funnel-shaped body 40 or another component or accessory of the beverage bottle, as explained in greater detail below. One or more protrusions 74 may be shaped to cooperate with the corresponding elongated recesses 53 of the twist-lock nozzle 52 as described below. A depth of the depression 73 in the top cover 70 may not exceed the width of the side wall 71 thereof, thereby facilitating using the top cover 70 as a stand for the funnel-shaped body 40 when the twist-lock nozzle 52 is attached to the twist-lock receptacle 72 of the top cover 70, as described in detail below.

[0071] In addition to, or instead of, a mechanical seal formed between the side wall 71 of the top cover 70 and the peripheral lip 43 of the funnel-shaped body 40, various other optional sealing arrangements may be provided, such as the inclusion of sealing gaskets, sealing O-rings, and other compressible sealing components, incorporated within the top cover 70 or as part of the external thread 46, as the invention is not limited in this regard.

[0072] The exact profile of the funnel-shaped body 40 curvature may be selected as needed based on specific design considerations. In one example shown in the drawings, the shape may be selected to maximize the volume of the powder retained by the funnel container 10 of the invention while facilitating the emptying of the content into the beverage bottle as described below.

[0073] A twist-lock nozzle 52 may be formed at the bottom opening 50 of the funnel-shaped body 40see FIG. 4. The twist-lock nozzle 52 may have an external shape to facilitate the engagement of the funnel container with a corresponding twist-lock receptacle 72 in a manner similar to what is described with regard to the twist-lock connection between the beverage bottle and various accessories thereof in my co-pending patent application Ser. No. 18/399,631 cited above.

[0074] As seen in a close-up front view of the twist-lock nozzle 52 in FIG. 8, one or more twist-lock portions may have one or more elongated recesses 53 with an opening 54 at the first end, a stop 55 at the second end, and a ramp 56 with a detent protrusion 57 in between. In the illustrated embodiment, the opening 54, elongated recesses 53, and stop 55 are configured to engage one or more protrusions 74 of the twist-lock receptacle 72 to achieve a releasable locking fit via the twist-and-lock arrangement. In the illustrated embodiments, there are two such sets of features circumferentially located and equidistantly spaced on each of the twist-lock nozzle of the funnel-shaped body 40 and the twist-lock receptacle of the top cover 70. These features may be configured for a releasably locking engagement of the twist-lock nozzle 52 with the twist-lock receptacle 72 when the funneled-shaped body 40 is first pushed into the cavity of the twist-lock receptacle 72 a downward direction and, second, rotated in a clockwise direction. In reverse, the twist-lock nozzle 52 disengages from the twist-lock receptacle 72 when it is first rotated in a counterclockwise direction, and then pulled upward.

[0075] As can be appreciated by those skilled in the art, the twist-lock design described above is just one non-limiting example of such releasable attachment. Other designs of various bayonet, friction fit, turn-and-lock, threaded, and similar releasable coupling and connecting attachment mechanisms are within the scope of the term twist-lock and are therefore included in the scope of the present invention.

[0076] As illustrated in the close-up cross-sectional views in FIGS. 7 and 9, the funnel-shaped body 40 may terminate in a bottom opening 50, which may be shaped in the form of the twist-lock nozzle 52. The inside surface of the bottom opening 50 may be shaped and sized to sealingly accept an elastic plug 20 to be inserted therein. To that end, the internal diameter D of the bottom opening 50 may be made to be smaller than the external diameter B of one or more sealing rings 26, which may be made as part of or as separate components (not shown) of the bottom plug 20. In further embodiments, the seal between the bottom plug 20 and the bottom opening 50 may be achieved by providing the internal diameter D of the bottom opening 50 to be the same or slightly smaller than the external diameter A of the bottom plug 20. In this case, inserting the bottom plug 20 may be done with a small compression thereof to snugly fit inside the bottom opening 50. Other similar sealing arrangements may be provided as the invention is not limited in this regard.

[0077] The bottom plug 20 may have a generally cylindrical shape and may be made from a food-grade elastic material. Generally speaking, such materials may be selected to be elastically compressible as well as odorless, tasteless, resistant to bacteria buildup, suitable to be used for food or beverages, reliable at temperature extremes, non-toxic, non-marking, non-allergenic, and capable of being manufactured into a final product using common manufacturing techniques. Common examples of such elastomeric materials include Ethylene Propylene Diene Monomers (EPDM), Fluorocarbons, Neoprene, Nitrile, and Silicones, although the invention is not limited in this regard.

[0078] The bottom plug 20 may have a deformable central protrusion 22 extending from the end 24 of the bottom plug 20. The deformable central protrusion 22 may be configured to be capable of removably positioning and retaining the bottom plug 20 at the opening 41 of the side tab 42, as seen in FIG. 10, FIG. 11, and FIGS. 12-15. Placement of the bottom plug 20 in opening 41 may be done as a storage arrangement while emptying the funnel container to avoid losing this small component during use.

[0079] As seen in FIG. 9, the bottom plug 20 may have an internal cavity 29 with a septum 30 across thereof, which may be configured to act as a handle and facilitate holding the bottom plug 20 during insertion and removal from the bottom opening 50 of the funnel-shaped body 40. A flange 28 radially extends from one end of the bottom plug 20. The flange 28 may serve as a stopper when inserting the bottom plug 20 into the bottom opening 50. The bottom plug 20 may be flush with the bottom opening when inserted therein, with only the flange 28 of the bottom plug 20 protruding therefrom. The flange 28 may have a thickness from about 1 mm to about 3 mm. A small thickness of the flange 28 is advantageous so as not to cause significant protrusion beyond the edge of the bottom opening. Such protrusion would otherwise necessitate a deeper recess in the corresponding portion of the lid, which, in turn, would limit the usable space available inside the funnel container 10. In embodiments, the flange 28 does not extend beyond the external size of the bottom opening so as not to interfere with the twist-lock engagement mechanism.

[0080] One side of the flange 28 may have a cut 27 designed to facilitate lifting and removal of the bottom plug 20 using a fingernail positioned under the flange 28. The size of the bottom plug may be selected to be the least obstructive during the use of the funnel container 10, such as to facilitate the transfer of powder to the water bottle 1000.

[0081] Circular or, in other embodiments, non-round flange 28 may be sized (dimension C) to be more than the internal diameter D of the bottom opening 50. In further embodiments, dimension C may be selected not to exceed the external dimension F defined by the twist-lock elements of the twist-lock nozzle 52. Alternatively, dimension C may be selected not to exceed the external diameter E of the bottom opening 50, which defines the elongated recess 53 of the twist-lock nozzle 52. Selecting the depth of the depression 73 to be sufficient to accept the twist-lock nozzle 52 and the flange 28 of the bottom plug 20 positioned inside to sealingly close off the bottom opening 50. This may be done to avoid any interference from the bottom plug 20 during the attachment of the twist-lock nozzle 52 to the twist-lock receptacle 72 of the top cover 40.

[0082] In use, the funnel container 10 may fulfill the first purpose of holding the supplement powder of the user's choice. To do so, the internal volume is made to be sufficient to accept commonly used daily or single doses of conventional supplement powders, as described above. The bottom plug 20 may be positioned to close off the bottom opening 50. The supplement powder may then be deposited into the funnel-shaped body 40, and the top cover 70 may be placed on top to seal off the funnel container 10 until the supplement is required to be mixed with the water or another fluid from the beverage bottle. To make the position of the funnel-shaped body stable, the twist-lock nozzle 52 may be inserted into the top cover 70. The top cover 70, in this case, may serve as a wide base or a stand for placing the funnel-shaped body 40 on a flat surface, as illustrated in FIGS. 16 and 17.

[0083] As seen in FIG. 18, the space between the bottom opening 50 and the bottom 76 of the depression 72 is sufficient to accept the bottom plug 20 positioned inside the bottom opening 50 as well as the flange 28 protruding downward therefrom. At the same time, the depression 72 does not extend beyond the depth of the sidewall 71 to ensure that there is full contact of the edge of the sidewall 71 with the supporting flat surface.

[0084] To deposit the supplement powder into the water or another beverage contained in the beverage bottle 1000, the funnel container 10 may be flipped upside down, the bottom plug 20 may be removed (and temporarily attached to the side tab 42), and the powder may be shifted from the funnel container 10 as directed by the funnel-shaped body 40 through the bottom opening 50 into the mouth 1010 of the beverage bottle 1000see FIGS. 19-21. The flip cap 1020 of the beverage bottle 1000 may have a twist-lock receptacle 1022 as part thereof (see FIG. 21), which is sized to be the same as the twist-lock receptacle 72 of the top cover 70. In this case, when the flip cap 1022 is closed, the funnel container 10 may be attached thereto for easy transport together with the beverage bottle 1000.

[0085] The twist-lock feature of receptacle 72 in the top cover 70 and the twist-lock nozzle 52 of the bottom opening 50 may be made to have the same size as other accessories of the beverage bottle 1000, thereby forming a universal adapter described in my other patent applications cited above.

[0086] FIGS. 24 and 25 show an alternative version of the top cover 70, in which a first twist-lock receptacle 72a and a second twist-lock receptacle 72b are positioned across the center of the top cover 70 and may be spaced apart equidistantly therefrom. The second twist-lock receptacle 72b may be identical to the first twist-lock receptacle 72a. In some embodiments, the distance between the centers of the twist-lock receptacles 72 may be equal to half of the diameter of the top cover 70. In other embodiments, that distance may exceed half of the diameter to accommodate larger accessories to be positioned side-by-side on the top cover 70.

[0087] Various combinations of accessories may be stacked together, assembled side-by-side, or stacked in a side-by-side arrangement as follows: [0088] a. stack up two or more funnel containers 10 together in a vertical arrangement as seen in FIGS. 22 and 23; [0089] b. attach more than one funnel container 10 or 12 of various sizes, filled with one or more individual powders as arranged side-by-side, as seen in FIG. 26, and [0090] c. mix and match stack-up arrangements by including other accessories, such as a tablet holder 14 or a phone stand and holder accessory 16, as seen in FIGS. 27-31.

[0091] Further details and examples of these other interchangeable accessories that may be equipped with the same twist-lock connector are described in my co-pending US applications cited above.

[0092] In further embodiments, the funnel container 10 may come in several sizes. One example seen in FIG. 26 shows a top cover 70 from a larger funnel container 10 having two twist-lock receptacles 72 spaced apart from each other along the top cover 70.

[0093] In further embodiments, a kit comprising a funnel receptacle 10 and at least one of a smaller funnel receptacle 12, a pill box 14, or a phone stand and holder accessory 16 may be provided. All of these additional accessories may include a twist-lock nozzle identical to the twist-lock nozzle 52 of the funnel-shaped body 40, so as to facilitate removable attachment thereof to the top cover 70 of the funnel container 10.

[0094] In a further example, each twist-lock receptacle 72a and 72b may accept one of a smaller funnel container 12, a pill box accessory 14, or other accessories of the beverage bottle 1000. This arrangement further allows placement of two or more smaller funnel containers 12 on top of a single top cover 70 designed to fit over a larger funnel container 10. This may be advantageous when the volume of powder required to be stored for a day of use exceeds the internal volume of a smaller funnel container 12.
