Patent Abstract:
A drinking vessel that has the capability to be stackable and which, by using regular water ice or dry ice, has the ability to maintain a cold temperature for the beverages while not diluting the potency of the liquid or diminishing the quality of the taste. The stackable aspect of the design allows the containers to be nestled within each other allowing for greater quantities of the vessels to be shipped at a single time. A sealable, removable bottom allows for the ice to be secured with the hollow chilling chamber. A handle, which may be formed into the vessel at the time of casting or may be attached after shipping, along with the base that is larger in diameter than the top because to the stacking feature, create the appearance of a traditional beer stein.

Full Description:
BACKGROUND 
       [0001]    1. Field 
         [0002]    The present invention relates to cold-liquid drinking vessels and more particularly to beer steins. 
         [0003]    2. Related Art 
         [0004]    In U.S. Pat. No. 4,424,990, White et al disclose thermo-chromic compositions which change color with temperature changes. These compositions are commercially available and are used in thermometers and novelty items, and simply reflect the ambient temperature of the liquids within the vessels. They do nothing to affect the temperatures or to keep the beverage cold. 
         [0005]    In U.S. Pat. No. 5,156,283, Sampson teaches that a beer stein should be of suitable material so as to not be conductive of heat and proposes a wooden stein. Further, Sampson teaches that decorative emblems can be embedded in the wood to increase the attractiveness of the drinking container, however this proposal has a limiting effect as to what materials may be used in the construction of the beer stein. 
         [0006]    Fremin, in U.S. Pat. No. 4,919,983 teaches that by using plastic thermo-chromic materials in forming a baby bottle, it is possible to indicate when the contents of the bottle are too hot to drink, but again, this does nothing to alter the temperature of the bottle contents.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0044]    The detailed description set forth below in connection with the appended drawings is intended as a description of various embodiments of the invention and is not intended to represent the only embodiments in which the invention may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the invention. 
         [0045]    The beer stein, with the base larger than the top lip, symbolically represents the art of brewing and drinking beer. Until now, there has been no way of economically providing the natural image of the festival at a beer festival as most of the beer at such events is served out of plain plastic or paper cups. By utilizing this present invention, fraternities at beer blasts can provide a drinking mug with the fraternity insignia on the side with the possibility of also providing a souvenir of the occasion. The additional bonus comes from being able to keep the beer chilled without diluting it with the water from melting ice. The present invention need not be restricted to beer containers as it is equally effective at keeping other beverages cold without the container having the requisite handle of the beer stein. For example, colas and other soft drinks can be kept cold without the unwanted effect of having them diluted by melting ice. Another benefit arising from the design of the present invention is, by using the detached handle, the ability of wholesalers to stack the drinking containers for ease of shipping great quantities. 
         [0046]    In the prior art, many inventors have experimented with the materials used in creating the beer mug and with decorative designs affixed to or imbedded in the containers, however no one has created a design that is stackable, larger at the bottom than at the top, and is able to maintain the coldness of the liquid. Most of these inventions demonstrate no utilitarian purposes beyond those exhibited by the original, conventional designs of time-honored beer steins as most are add-on advertising gimmicks. 
         [0047]    Currently, there does exist a double-wall, plastic freezer mug that contains a gelatinous liquid that is permanently sealed within the walls. This freezer mug is to be placed in the freezer for an extended time to achieve a frozen state for the contained liquid. The significant differences between this item and the present invention is that (1) it is not stackable, (2) it is not designed to ever be disposable, and (3) its design is not applicable to low-cost materials making it impractical for use at public ventures such as beer festivals. 
         [0048]    Beer steins and other vessels for consuming liquids have traditionally been made of a variety of materials including but not limited to glass, ceramic, plastic, Styrofoam, and metal. Ideally, a drinking container is one that should be not conductive of heat, will not affect the taste or consistency of the beverage, and will not drip condensation from the air which has accumulated on the outside of the container onto furniture or other surfaces. All of the above materials, with the exception of Styrofoam will, in most surrounding climates that are warmer than the liquid contents of the container, collect condensate on the exterior walls of the container which will then run down onto the surface upon which the container is sitting. A vessel that is designed to collect the condensate within a hollow chamber and which has that said hollow chamber insulated from the warmer outer temperatures both on the sides and on the bottom by a Styrofoam lining will effectively combat that problem. 
         [0049]    With most liquids such as soda, tea, milk, or lemonade, it is desirable that they be consumed at a cold temperature, and this is accomplished by drinking rapidly or by floating ice in the liquid within the container. When ice made from solid water is floated in the said liquid, it will melt in the liquid, turning the ice back into water and thereby reducing the potency of the liquid that is being consumed and making it less concentrated than when originally poured. If ice is not placed in the liquid for cooling purposes, the temperature of said liquid immediately begins to become heated by the ambient external temperature making it unpleasant to drink within a short period of time. By keeping the coolant, which effectively might be regular ice or dry ice, separate from the contained liquid, a desirable cold temperature can be maintained while at the same time retaining the original potency of the liquid. 
         [0050]    Because beer steins have traditionally been made of various materials—metal, glass, and ceramic being chief among the materials being used, and with modern-day disposable cups being made of paper, wax-covered paper, plastic, and Styrofoam, the stackable stay-cold beer stein is designed in such a manner as to permit interchangeable parts of varying materials. For instance, the outer cone shell may be made of plastic lined with Styrofoam and then with reflective foil while the inner cup section can be made of plastic or ceramic or glass depending upon which material is most pleasing to the lips of the user. Reusable steins can have a screw-on, insulated bottom while disposable cups may have a snap on, plastic bottom for securing the dry or water ice coolant within the hollow, cooling chamber. 
         [0051]    Because the stackable, stay-cold beer stein will be desirable for use at festive, memorable occasions, logos of fraternities, businesses, of festivals may be either printed on the outsides of the mugs, or they may be affixed to the outsides by peel-off labels such as those used on the year ID tags of automobile license renewals or from sheets printed in a manner similar to postage stamps. Likewise, the detached handles may be attached to the mugs after shipment by using peel-off tape that is already affixed to the ears prior to shipping. 
         [0052]    The present invention, a stackable, stay-cold drinking vessel, is shown in  FIG. 24 ,  FIG. 25 , and  FIG. 26 . The detailed description set forth below in connection with the drawings is intended as a description of various embodiments of the invention and is not intended to represent the only embodiment in which the invention may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the invention, however it will be readily apparent to those skilled in the art that there may be overlapping specifics and that the invention may be practiced without these specific details. 
         [0053]    Embodiments of the present invention relate to a drinking vessel that, with the introduction of water ice or dry-ice into a specially designed chilling compartment has the ability to maintain a cold temperature to the liquid in the consumption part of the vessel without diluting is potency. This design feature that is built into the vessel also has the ability to allow the vessels to be stacked thereby allowing for greater ease in shipping. The vessel may be made of a variety of materials—i.e. paper, wax coated paper, plastic, Styrofoam, ceramic, metal, glass, or any combination thereof. The invention can be made to be disposable, or it can be made to be kept for re-use or to save as a souvenir item. 
         [0054]    The basic concept for the shape of the stay-cold beer stein could be said to be derived from a slender cone that has been truncated into three equal heights ( FIG. 28 . and  FIG. 29 ). The circumference of the top  41  of the base section  42  is congruent with the circumference of the base  41  of the middle section  40 . When the middle section  40  of the cone is inverted  FIG. 30 , inserted into the base section, and sealed at the top, it forms the basic design for the stay-cold beer stein. There is no purpose for the top section of the cone in this design. 
         [0055]    Also, in its most basic form, this present invention would be made of a disposable material such as thin plastic, paper, or wax covered paper, and it would consist of four separate pieces—the stackable structure  1 , the attachable handle  3 , the adhesive tape  13  for attaching the handle to the stackable structure, and the snap-in bottom  19  for securing the ice within the chilling chamber  4 , shown in  FIG. 1 ,  FIG. 2 ,  FIG. 25  and  FIG. 26 . If the inner vertical annular supports  21  and the outer vertical annular supports  20  on the snap-in bottom  19  are tall enough and fit under a drip cap (see  FIG. 2  and  FIG. 8 ) the water from melting ice will not seep out onto the table upon which the stein might be resting. Rather, it will be collected in the closing ring  23  (of  FIG. 8 ) or  37  &amp;  38  (of  FIG. 27 ) of the snap-in bottom. 
         [0056]    One reason for having an attachable handle for the beer stein is to maintain the stackable aspect of the design for ease of shipping as shown in  FIG. 10 . For his reason, upper openings  10  and lower openings  14  may be designed into the basic structure allowing for the handles  3  to be attached after shipment. To achieve this end, adhesive tape  13  with a pull off tab similar to double sticky tape is attached to the support surface  15  on the handle. When the upper support nodule  11  and the lower support nodule  5  are inserted into the said upper and lower openings, the said tape presses against a section on the outer funnel  12  and this causes the handle to become permanently affixed to the funnel of the stackable beer stein. See  FIG. 1 ,  FIG. 2 , and  FIG. 3 . An alternate design for the upper support nodule  FIG. 7  extends farther  22  into the chilling chamber and provides a hook shape on the top  18  for the purpose of locking the upper support into the chilling chamber and giving additional support without the danger of the handle being pulled out by the force of lifting. A third handle concept would be for the slot  44   FIG. 30  in the outer shell to be simply an indention in the exterior and not penetrate completely through thereby leaving the chilling chamber water tight. The support nodule  45  would still be affixed inside the slot with double sticky sealing tape  46 . If the design concept is to be used as a simple glass with a chilling chamber for drinking such beverages as colas, soda pops, tea, or milk, there would be no requirement for the support nodule holes as a handle would not be required. However, since the shape would taper upward, a gripping surface  28 ,  FIG. 11 , might be designed into the shape to aid in lifting the glass. Aside from the novelty of drinking out of a vessel where the bottom has the appearance of a greater diameter than the top rim, with either design, the shape would still be more stable when resting on a table because there would be more weight at the bottom than at the top due to the nature of the design. The design lends itself to having the lower rim of the funnel shape  16 , as shown in  FIG. 2  &amp;  FIG. 4 , rather than the bottom lid resting on the table for the sake of stability. For the ease of inserting and removing the bottom lid from the main structure, a hand grip  26 , as shown in  FIG. 8  &amp;  FIG. 19 , is designed into the lid, and the bottom, interior of the one-piece casting  7  should be sufficiently shallow enough for this to happen. 
         [0057]    In order for the chilling chamber to function most effectively, a Styrofoam funnel-shaped insulating liner with a reflective inner lining  24 , as shown in  FIG. 9  &amp;  FIG. 22 , may be designed into the outer funnel portion of the basic structure. Also for insulating purposes, an annular Styrofoam ring  25  may be included with the snap-in or screw-in bottoms. In either the inexpensive version of all plastic or the more permanent version of the invention, if the bottom of the interior section of the one piece casting  7  does not extend to the bottom circumference ring  16  of the exterior section, then there would be no need for the donut hole in the bottom lid, and it would be cast as one piece  37 . In this configuration, the thin plastic outer vertical annular supports  20  on the snap-in would extend farther into the hollow of the outer ring. It would also curve outward in a semi-circular shape before curving inward  38 , to fit snugly under an annular drip cap  39  to prevent the melted water from seeping out onto the support upon which the stein is sitting, and the bottom lid would become a holding receptacle for the melted ice. Since the upper circumference is curving inward, this would provide for easier installation of the lid as well as creating a tighter, more leak-proof seal. 
         [0058]    In its more permanent and expensive form, this present invention would be made of more durable materials such as metal, heavy plastic, ceramic, glass, Styrofoam, or combinations of the said materials, and it would be suitable for being washed. It could be made of as many as five different parts which could possibly be assembled by screwing the parts together as shown in  FIGS. 19 ,  20 ,  21 ,  22 , &amp;  23 . The purpose for being able to disassemble all the parts would be for most effective dishwasher cleaning. The outer funnel-shaped shell  8  would be lined with Styrofoam  24 , as shown in  FIG. 22 , and would be threaded at the top rim  35 . 
         [0059]    Likewise, the inner glass would be threaded at the top rim  36 , as shown in  FIG. 23 , in order to screw into the outer funnel-shell. The inner glass of the tankard would also be threaded at the bottom rim  32 , as shown in  FIG. 17  &amp;  FIG. 23 , to receive the inner threaded portion  33  of the bottom lid. The outer funnel-shaped shell would also be threaded on the inside of the bottom rim  34 , in order to receive the outer threaded portion of the bottom lid  35  (see  FIG. 22 .) 
         [0060]    When the bottom lid is screwed in tightly into the assembled beer stein or drinking vessel, a water tight seal is formed between the abutting surfaces  28 ,  19 ,  30 ,  31  as shown in  FIGS. 17 ,  18 , &amp;  19 . 
         [0061]    Functionally, the most effective way to introduce ice into the chilling chamber of the stay-cold beer stein would be to fill the chilling chamber with water to a predetermined fill-line and place it inverted into the freezer. When the stein is then removed to be used, the water-tight bottom could be affixed and the vessel would be ready to be filled with any preferred beverage. Secondly, the most practical, time-efficient, and cost effective way of introducing ice into the chilling chamber is simply to scoop crushed ice into the vessel by using the handle as a scoop and then inserting the removable water-tight bottom. Another way to introduce the ice would be to have the ice preformed into the requisite funnel shape by having plastic or polyurethane ice trays that are designed to accomplish this end as shown in  FIG. 31  and  FIG. 32 . By this method, trays  47  are formed having an outer truncated cone  48  with a sealed bottom  49  and an inner truncated cone  43  with sealed top  51  that together form a freezing chamber  50 . Ultimately, for use in commercial establishments, ice machines could be manufactured to produce the funnel-shaped ice that would be necessary to accommodate the business at a commercial establishment. 
         [0062]    In order to make any drinking glass or beer stein event specific to the occasion or sponsor specific, the business, club, or organization logo can be printed on the exterior of the mug at the manufacturing plant, or it may be affixed later at the usage destination by using paste-on decals  17  as shown in  FIG. 5 . 
         [0063]    Referring back to  FIG. 1  and  FIG. 2 , aspects of the present invention relate to a stackable stein that includes a body. The body includes an outer cylindrical wall  106  wider at a first base end  105  than at an opposite first upper end  107  such that the outer cylindrical wall  106  slants outwardly at its bottom. The stein body also includes an inner cylindrical wall  104  having a second base end  111  and an opposite second upper end  109 . The body includes a frustoconical annular region, or cavity,  114  formed between an outer surface  120  of the inner cylindrical wall  104  and an inner surface  121  of the outer cylindrical wall  106 . The inner and outer cylindrical walls  104 ,  106  are configured such that a) the second base end  111  comprises a closed base region  108 , b) the first upper end  107  and the second upper end  109  form a common upper region  102 , and the first base end  105  and the second base end  111  extend to substantially a same orthogonal distance d 1  (see  FIG. 1 ) from the common upper region  102 . The stackable stein also includes a detachable bottom  110  configured to releasably attach to the first base end  105 . The stackable stein may also include a detachable handle  112  configured to releasably attach to at least an outer surface of the outer cylindrical wall. 
         [0064]    As a result of this construction, the stein body is stackable or nestable because at any particular orthogonal distance d 2  from a top of the common upper region  102  towards the first base end  105  an outer diameter of the outer cylindrical wall  106  is less than or substantially equal to an outer diameter of the frustoconical annular region  114  at approximately that same particular orthogonal distance d 3  from a bottom of the common upper region  102 . The stein of  FIG. 1  can thereby be stacked together as shown in  FIG. 10 . The distance d 3 , which is “approximately d 2 ” from the bottom of the common upper region  102 , is “approximate” because the steins (as shown in  FIG. 10 ) do not nest perfectly. There is a gap  130  between the bottom of the common upper region  102 A of an upper-located stein and the top of the upper common region  102 B of a lower-located stein. If this gap  130  did not exist, then the relationship about the outer diameter of the outer cylindrical wall being less than the outer diameter of the frustoconical annular region would be true for d 2 =d 3 . However, the gap  130  can be as much as a few millimeters and, thus, the relationship about those outer diameters holds true for d 2 ≈d 3  where d 3  is larger than d 2  an amount the same as the size of the gap  130 . 
         [0065]    Also, in most instances, the outer diameter of the outer cylindrical wall at that particular orthogonal distance is approximately equal to the outer diameter of the frustoconical annular region at approximately that same particular orthogonal distance. This relationship expresses the construction that, when nested, the gap  132  (see  FIG. 10 ) between two adjacent stein&#39;s outer cylindrical walls is negligible in size and can be a millimeter or less. 
         [0066]    When a plurality of steins are stacked together, the plurality of steins are nested together in an arrangement from a bottom stein  134  to a top stein  136  whereby the common upper region  102 B of a lower stein  134  in the arrangement is fitted within the frustoconical annular region of an adjacent, next-higher stein  136  in the arrangement. The positional terms such as “bottom”, “upper”, “lower”, etc. as used herein are used for convenience with respect to a particular frame of reference illustrated in the figures. However, one of ordinary skill will recognize that there terms can be changed without departing from the scope of the present invention. For example, the nested arrangement of  FIG. 10  can also occur if the frame of reference were flipped 180 degrees so that a “lower” item” would then become a “higher” item. 
         [0067]    The previous description is provided to enable any person skilled in the art to practice the various embodiments described herein.
