## Background
RELATED APPLICATIONS
This non-provisional application claims priority to provisional application No. 61/400,115 filed Jul. 21, 2010 by Donald Allen Scott for the same titled invention: Nesting Stemware Glass.


FIELD
The present invention relates to bottles, jars and receptacles, and more specifically to drinking vessels having a base and a volume defining body for containing liquids which are detachable from each other respectively. A base and a body can be attached in at least two configurations, a first configuration resembling conventional drinking vessel which is conducive to drinking liquids from the volume defining body and a second nested configuration that minimizes the space required for storage of the base and body and reduces the risk of breakage when not in use such as during transport.
BACKGROUND
Stemware is available in a variety of shapes and sizes and may be used for purposes such as carrying, serving, or drinking beverages. For example when consuming wine, champagne, beer, brandy, or cocktails, stemware is often used not only as means for drinking such a beverage, but also as a means of increasing the rate of oxidation and inducing heightened aromas.
One of stemware's uses is in the consumption of wine, where it is generally recognized that olfactory, visual and taste characteristics of any given wine are best displayed and best judged in a traditional transparent wine glass. Conventional wine glasses typically have a foot, a stem, and a bowl defining an interior volume where the bowl is of a parabolic shape.
Stemware glasses are available in many different shapes and sizes, and frequently the shape and size is dependent upon the liquid intended to be served using the particular stemware glass. For instance, stemware glasses for red wine typically have a bowl with a larger diameter than those stemware glasses used for white wine. One reason for this is because a stemware glass with a larger diameter bowl provides a larger surface area for the liquid in the bowl to interact with oxygen in the air, this process being commonly known as oxidation. Oxidation is generally considered to be desirable when drinking red wine because the complex flavors, oils, and spices present in red wine mature and meld after being exposed to air. In contrast, the bowl of many white wine glasses is narrower than that of red wine glasses which reduces the rate of oxidation. Reducing the rate of oxidation is generally thought to aid in containing the crisp, clean flavor that many white wines possess. Beyond the noticeable differences between the typical red wine stemware glass and a white wine stemware glass, other drinks customarily consumed from stemware glasses are designed to enhance the consumers' olfactory, visual, and taste senses during consumption such as champagne flutes, sherry glasses, brandy snifters, beer tulips, and beer goblets.
Stemware can be made of many different materials including transparent materials and opaque materials. Typically, stemware is made of transparent glass which allows the user of such stemware to visually inspect the color and clarity of the liquid that fills the bowl of such a stemware glass. Blown glass, fused glass and lead crystal are a just a few examples of materials of which stemware is made. Unfortunately, glass is breakable and one of the drawbacks to using glass stemware is its fragile nature where even a relatively minor impact of setting the stemware glass down or a hard surface may cause the stem to break separating the foot from the bowl making the glass unusable.
As another example, when consuming beer, the shape of the stemware will affect foam development and retention. The foam or head created by pouring beer into the stemware bowl acts as a net for compounds that evaporate from the beer to create its aroma, such as hop oils, yeast, fermentation byproducts, fusels, fruity esters, or other additives.
Further, the shape of stemware, including the narrowed upper flume, inherently precludes stacking of multiple glasses for space efficient storage. There exists, therefore, a need to make further improvements to many of the various forms of stemware which allows stemware to be more easily stored, protects stemware from damage during storage and transport, and stemware which can utilize replacement and customization parts all without sacrificing the benefits that stemware gives when consuming beverages. The present invention fulfills these needs and provides further related advantages.
My invention does not reside in any one of the identified features individually but rather in the synergistic combination of all of its structures, which give rise to the functions necessarily flowing therefrom as hereinafter specified and claimed.

The preferred embodiment and alternate embodiments are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout.
My nesting stemware drinking vessel generally provides a body 34 and a base 10.
FIG. 1 illustrates an example of a known stemware drinking vessel 50 having three main sections: a bowl 51, a stem 52 and a foot 53 that are integral with one another. The stem 52 connects the bowl 51 with the foot 53. The foot 53 is typically designed to allow the stemware drinking vessel 50 to rest stably on a flat surface. It is to be appreciated that the shape of a stemware drinking vessel 50 is at least partially dependent upon the diameter of various sections of the bowl 51 which determine the generally parabolic shape of the bowl 51.
FIG. 2 illustrates a base 10 of a nesting stemware drinking vessel in accordance with the present disclosure. The base 10 includes a stem 25 which may be integrally formed with foot 11 to form a unitary structure. Upper surface 12 of the foot 11 has plural spacedly arrayed locking protrusions 13 that are incorporated into the upper surface 12 of the foot 11 and extend radially outwardly away from the stem 25. The plural locking protrusions 13 define a first circumference 17 that extends about the upper surface 12 of the foot 11 adjacent lower portions 16 of the locking protrusion 13 opposite the stem 25 and a second circumference 17a that extends about the upper surface 12 of the foot 11 proximate upper portions 15 of the locking protrusions 13 opposite the stem 25. The second circumference 17a is larger than first circumference 17.
In the preferred embodiment, base 10 has three spacedly arrayed locking protrusions 13; however it is to be appreciated that in alternative embodiments (not shown) plural spacedly arrayed locking protrusions 13 which may be two, or more than two, locking protrusions 13 could be included in alternate embodiments. End portion 14 of each locking protrusion 13 opposite the stem 25 is angled downwardly and inwardly such that upper portion 15 of locking protrusion 13 extends radially outwardly further from the stem 25 than lower portion 16 of the locking protrusion 13 adjacent the upper surface 12 of the foot 11.
Releasable attachment means 26, such as but not limited to, threads 26a are carried at end portion 27 of the stem 25 opposite the foot 11 to releasably interconnect the base 10 with the body 34. In the preferred embodiment, the releasable attachment means is threads 26a. 
FIG. 3 illustrates body 34 of a nesting stemware drinking vessel in accordance with the present disclosure. The body 34 can include a bowl 35. Upper portion of the body 34 defines an aperture 36 below which is defined an interior volume 37 for containing liquid. The aperture 36 has a circumferential edge 38 that is rolled inwardly providing an inner circumferentially extruding lip 39 having a diameter 42 smaller than exterior diameter 41 of the aperture 36. (FIG. 3.) Diameter 42 of the lip 39 is substantially similar to the first circumference 17 encircling the lower portions 16 of the locking protrusions 13 carried on the upper surface 12 of the foot 11 which provides for frictional engagement between the lip 39 and the locking protrusions 13 to positionally maintain engagement of the base 10 with the body 34 while in a nested configuration. (FIG. 6).
As shown in FIG. 5, the body 34 has a stem mount 40 at lower exterior portion of the body 34 opposite the aperture 36. It is to be appreciated that the stem mount 40 can be structurally interconnected to the body 34 by any number of different techniques and alternatively the stem mount 40 may be integrally molded into the body 34. The stem mount 40 incorporates a mating portion of the releasable attachment means 26 carried by the stem 25. In the preferred embodiment, the stem mount defines threads 40a as the mating portion of the releasable attachment means 26.
It is to be appreciated that varying the dimensions of the body 34 such as the height, the depth, the diameter of the bowl 35, or the diameter of aperture 36, can alter the general shape and appearance of the body 34 and the nesting stemware drinking vessel without affecting its functionality. As such, varying the appearance of the body 34 and base 10 to serve various stemware markets is within the scope of the subject disclosure.
FIG. 7 illustrates a view of a transparent nested stemware drinking vessel in accordance with the subject disclosure wherein frictional engagement of the locking protrusions 13 with the lip 39 causes the inverted body 34 to be positionally interconnected with the base 10. When nested, the stem 25, releasable attachment means 26, and locking protrusions 13 reside within the interior volume 37 defined by the body 34.
FIG. 6 illustrates a view of an opaque nested stemware drinking vessel in accordance with the present disclosure.
FIG. 4 illustrates a transparent nesting stemware drinking vessel in drinking configuration. In this configuration the base 10 is releasably connected to the body 34 to form a conventional stemware drinking vessel. The body 34 is attached to the base 10 by means of threads 26a that extend axially from upper end portion 27 of the stem 25 and the threads 40a defined by stem mount 40. It is to be appreciated that other methods of connecting the base 10 with the body 34 can exist to those skilled in the art such as, for example, male threads extending from the stem mount and female threads defined within the stem mount 40, snap-type friction connections (not shown), spring based connections (not shown) and the like.
FIG. 8 illustrates a beer globe in a drinking configuration, having a different shaped body 34, a short stem 25 and a base 10 that is similarly detachable from the stem mount 40 and inverted to be carried within the aperture 36 defined by the body 34.
It is also to be appreciated that various embodiments described herein can be implemented with a number of different materials including where the body 34, the base 10, the stem 25 and foot 11 are made of different materials.
Having described the structure of my nesting stemware drinking vessel its operation may be understood.
The body 34 is interconnected with the base 10 by means of the mating portions 26a, 40a of the releasable interconnection 26 carried by the stem mount 40 and the upper end portion 27 of the stem 25 opposite the foot 11 to form a configuration similar to a known stemware drinking vessel that is suitable for containing liquids for drinking.
To change the nesting stemware drinking vessel from a drinking configuration (FIG. 4) to a nested configuration (FIG. 7) for storage and transport, the mating portions 26a, 40a of the releasable connecting means 26 are disconnected, such as by rotating the body 34 and base 10 axially in different directions. The body 34 is inverted relative to the base 10 and is positioned so that the stem 25 extends into the interior volume 37. The body 34 is forced axially downwardly onto the base 10 so that the lip 39 engages with and frictionally slides over upper portions 15 of the locking protrusions 13 to be positionally maintained at circumference 17 so that the upper portions 15 of the locking protrusions 13 frictionally engage with inner circumferential wall of the body 34 spacedly adjacent the circumferentially extending lip 39.
In the above description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various embodiments. It may be appreciated, however, that the various embodiments can be practiced without these specific details. Additionally, numerous modifications and variations of the subject disclosure are expected to occur to those skilled in the art upon consideration of this detailed description. Moreover, it should be recognized that the configurations of the nesting stemware drinking vessel could be modified in an aesthetically pleasing way. As such, the subject disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the subject matter to those skilled in the art. Consequently, such modifications and variations are intended to be included within the scope of the subject disclosure.
