DETAILED DESCRIPTION
As indicated above, the invention provides an apparatus and device for dispensing a quantity of liquid from a vessel.
Referring now to FIGS. 2A-D, various views of an apparatus 200 according to an embodiment of the invention are shown. FIG. 2A shows a side perspective view of apparatus 200. As shown, apparatus 200 includes a base portion 230 having a well 232 on its inner surface. That is, well 232 comprises a depression within base portion 230. From a bottom surface of well 232 and extending upward is a hollow spout portion 250 having at least one opening 252 for passage of a liquid. Base portion 230 further includes a rim 236 and a plurality of ridges 234A-C, the functions of which will be described in greater detail below.
Apparatus 200 is preferably a one-piece molded apparatus and may comprise any number of materials, as will be recognized by one skilled in the art. A particularly preferred material is polypropylene. Another suitable material is linear low-density polyethylene. Similarly, apparatus 200 may be sized for use with vessels of any size.
FIG. 2B shows a side cross-sectional view of apparatus 200. As shown, hollow spout portion 250 includes a pair of openings 252A-B and an optional tube member 258 residing on an underside of apparatus 200. Tube member 258, as in known apparatuses and as will be described in greater detail below, may extend downward from apparatus 200 into a reservoir of fluid.
FIGS. 2C-D show, respectively, top and bottom cross-sectional views of apparatus 200. As shown, apparatus 200 has a circular shape in cross-section, although this is not essential. Apparatus 200 may have any cross-sectional shape, depending on the corresponding cross-sectional shape of an opening in a vessel to which apparatus 200 may be incorporated. In FIG. 2C, it can be seen that well 232 and rim 236 have different diameters, such that the diameter of rim 236 is greater than that of well 232. An opening into which apparatus 200 may be inserted would have a diameter intermediate that of well 232 and rim 236, such that well 232 may reside within the opening and rim 236 prevents passage of apparatus 200 through the opening.
In FIG. 2D, apparatus 200 is shown having eight ridges 234A-H. Ridges are provided in order to increase friction between apparatus 200 and an opening into which apparatus 200 may be inserted, thereby improving the retention of apparatus 200 within a vessel (described below) during transit and use. Where employed, an apparatus 200 according to the invention preferably includes at least two ridges and more preferably includes at least three ridges. In any case, it is preferred that the ridges be evenly distributed around a circumference of apparatus 200. For example, as shown in FIG. 2D, the eight ridges 234A-H are evenly distributed about the circumference of apparatus 200 (i.e., every 45 degrees about the circumference).
FIGS. 3A-B show a dispensing device 300 according to an embodiment of the invention. As shown, device 300 includes a vessel 310 (shown here as a bottle) having a neck 316 and an opening 314 into which apparatus 200 may be inserted. Once so inserted, well 232 resides within vessel 310 itself, rather than neck 316. That is, well 232 resides below the point at which neck 316 meets opening 314. As a result of this arrangement, at least a portion of the quantity of liquid 322 transferred from reservoir 312, i.e., the portion within well 232, resides within a space within vessel 310. For example, as shown in FIG. 3A, the total height A of the liquid 322 comprises a portion (B) above well 232 and a portion (C) within well 232. In effect, then, the height of liquid 322 is reduced by height C, as compared to known devices that do not include a well residing within the vessel 310.
The result of such an arrangement is shown in FIG. 3B. Here, device 300 is angled (at angle β, its “pouring angle”) such that liquid 322 may be dispensed from device 300. As can be seen, the reduced height of liquid 322 described above enables device 300 to be angled to a greater angle from vertical than known devices (see angle α in FIG. 1C) before liquid 322 is first dispensed. Preferably, angle β is between about 67 and about 71 degrees, more preferably about 69 degrees.
While neck 316 is shown as part of vessel 310, it should be recognized that neck 316 (or any similar container portion) may be incorporated into apparatus 200 itself, such that neck 316 (or container portion) substantially surrounds hollow spout portion 250 (FIG. 2B) before apparatus 200 is inserted into opening 314 of vessel 310.
FIG. 4 shows an alternative device 400 according to the invention in comparison with a known device 100, such as that of FIG. 1C, in order to illustrate yet another advantage of the present invention. Where a preferred pouring angle α has been achieved using a known device 100, any change in the diameter (i.e., greater or smaller) of dispensing apparatus 120 will necessarily result in a change in the height (i.e., decrease or increase) of liquid 122 and a corresponding change in the pouring angle (i.e., increase or decrease). The use of a dispensing apparatus 120 having a greater diameter may be desirable for any number of reasons, including, for example, appearance of device 100, ease of dispensation of liquid 122 into another container, mating with an opening 114 of predetermined size, etc.
Device 400 includes a dispensing apparatus 420 having a diameter greater than that of device 100, yet pouring angle α is approximately the same as that of device 100. As noted above with reference to FIG. 3A, this is attributable to the portion of liquid 422 residing within well 432 and the corresponding decrease in the height of liquid 422, as compared to a dispensing apparatus having no well 432 within vessel 410.
The foregoing description of various aspects of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously, many modifications and variations are possible. Such modifications and variations that may be apparent to a person skilled in the art are intended to be included within the scope of the invention as defined by the accompanying claims.
