DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS
(14) Referring to FIGS. 1-4 of the drawings, FIG. 1 is a perspective view of a stackable liquor glass 1 in accordance with the present invention. The stackable glass 1 includes a stem 3 and a bowl 5. The bowl 5 is sealed off from the stem 3 of the glass 1 at a bottom surface 14 of the bowl 5 so that fluid in the bowl 5 does not pass into the stem 3. The stem 3 has an opening 13 at the bottom of the stem wherein residual washing/rinsing liquid collects when the glass 5 is stacked in an upside down arrangement as shown in FIG. 3A. The stem 3 is formed as an enclosure within the bottom portion of the glass 1 with holes 2 placed equidistantly about the stem enclosure 6, each separated by 90 degrees of rotation. There are preferably four (4) holes 2 about the stem enclosure 6 of the glass 1 (see FIG. 2). The holes 2 eliminate vacuum formation caused by the stacking of the glasses 1 when the hot, wet glasses 1 cool to ambient temperature. The glass 1 of the present invention also includes a drain 7 between the stem 3 of the glass 1 and the bowl 5 (see FIG. 2). The drainage pathway links the enclosure 6 and an exit formed as a hole or opening 12 for liquid just beneath the bowl 5 when the glass 1 is in an upright position (conversely, located above the bowl in a stacked, upside-down arrangement (see FIGS. 2, 3 and 4). The drain 7 provides an asymmetric pathway or passage for residual rinsing water to exit the enclosure 6 through the opening 12 when the glass 1 is in its upside down stacked arranged position. The drain 7 is of ample diameter to avoid capillary action of residual rinsing water for borosilicate, commercial, and lead glass. FIG. 2 shows an individual glass 1 from a perspective view showing the drain 7 and one of the holes 2. As can be seen, the stem 3 is contained in the bottom portion of the glass 1 and has a set of holes 2 through which air can egress from the enclosure 6 through the holes 2 to outside of the glass 1.
(15) In addition the glass 1 of the present invention includes a flat surface 8a on which another of the stacked glasses 1 can rest its resting base 8b in stacked position on as can be seen in FIG. 3. The flat surface 8 acts as a shelf for the stacked glass 1 to rest upon.
(16) FIG. 3 shows the glasses 5 of the present invention in a stacked arrangement where each glass rests in an upside down position on flat surface 8 of the glass of which it is housed inside. The flat surface 8 can be manufactured in one piece with the glass 1 or adhesively connected or otherwise bonded to the inside of the glass 1 as shown in FIG. 3.
(17) FIG. 4 shows an individual one of the glasses 1 from a top view showing the drain 7 and the holes 2.
(18) FIG. 5 is a perspective view of a stackable glass 10 in accordance with an aspect of the present invention. The stackable glass 10 includes a stem 30, a base 60, and a bowl 50. As shown in FIG. 6, the bowl 50 is sealed off from the stem 30 of the glass 10 at a bottom surface 140 of the bowl 50 so that fluid in the bowl 50 does not pass into the stem 30. In one embodiment, the stem is part of the base. In one embodiment, the bowl 50 has a fill line 55. The fill line 55 can be etched, printed, molded as a score, or the like. The glass 10 is preferably glass. However, any suitable material such as a polymer or plastic can be used to make the glass. The glass can be mold blown, injection molded, press molded, blown, a press and blow method, or the like.
(19) The base 60 has at least one opening 65. In one embodiment, the opening is configured as a slot running from a distal end of the base 60 to the stem. While shown as a slot, the opening can also be configured as a hole 2 as shown in FIG. 11. Alternatively, other shapes including ovals, squares, stars, rectangles, and the like can be used. Preferably, there are three slots equidistantly spaced about the base, as shown in FIG. 9, but there can be more than three slots or openings.
(20) The base 60 defines a hollow space. Arranged in the base 60 is a raised portion 70, also referred to as a central upstanding punt or punt. The raised portion 70 tapers towards the wall of the base 60 forming a moat 75. The one or more slots or openings meets the bottom of the moat as shown in the cross-sectional view in FIG. 6. In this manner, any liquid in the moat will drain from the moat 75 via the openings 65. The base 60 of the stackable glass 10 includes the annular moat 75 defined between the wall of the base and a central upstanding punt 70. In this embodiment, the punt 70 defines an upstanding structure extending angularly away from the bowl 50 and inwardly at an angle toward base 85. As shown in FIG. 12, the base 60 comprises an outer wall 61 and an inner wall 63. The vents are arranged proximate to inflection point 76, which is where the inner wall 63 meets the rise of the punt 70.
(21) In one embodiment, the bottom of the moat, which is the point at which the base 60 meets the tapered edge of the raised portion 70 is substantially planar. In one embodiment, the bottom of the moat, which is the point at which the base 60 meets the tapered edge of the raised portion 70 is not planar such that the one or more openings are arranged at low points of the moat for drainage purposes. The moat 75 is tapered to direct fluid to the one or more openings 65.
(22) Residual washing/rinsing liquid collects in the moat 75 when the glass 10 is stacked in an upside down arrangement as shown in FIG. 7. The one or more slots 65 eliminate vacuum formation caused by the stacking of the glasses 10 when the hot, wet glasses 10 cool to ambient temperature. The one or more slots also functions as a drain so that the washing/rinsing liquid that collects in the moat 75 can drain.
(23) The glass 10 of the present invention includes a flat surface 80 on which another of the stacked glasses 10 can rest its resting base 85 on, in stacked position, can be seen in FIG. 7. The flat surface 80 acts as a shelf for the stacked glass 10 to rest upon. The resting base 85 can be seen in FIG. 8. It should be noted that the slot 65 can traverse the entire base 60 or only a portion of the base 60. As shown in FIG. 9, the slot 65 does not form a break in the resting base 85, which is the glass base. The slot 65 must meet the moat 75 to provide a drain from the moat 75.
(24) FIG. 7 shows two glasses 10 in a stacked arrangement where each glass 10 rests in an upside down position on flat surface 80 of the glass of which it is housed inside. The flat surface 80 can be manufactured in one piece with the glass 10 or adhesively connected or otherwise bonded to the inside of the glass 10.
(25) FIG. 10 is a 500 ml glass according to one embodiment of the invention. Other dimensions are conceivable. The present embodiment is provided as one specific example of a glass in accordance with the present invention. The glass has an overall height of about 5.9 inches. As shown, the mouth of the glass is about 3.5 inches. The widest part of the bowl 50 is about 4.75 inches. The opening 65, configured as a slot is about 0.1 inches wide, and preferably has a 0.05 inch radius fillet. As shown in FIG. 11, the width of the resting base 85, which is the base of the glass 10, is about 0.45 inches. The corresponding flat surface 80 is also about 0.45 inches. Preferably, when the glasses are stacked, there is a 4 mm gap between the mouth of a first glass and the bowl of a second glass.
(26) FIG. 12 is similar to FIG. 6 except the stem 30 is shortened or not present. The wall of the base is supports the bowl directly. As shown, the glass can have a slot 65 or a hole 2 arranged at the moat 75. The Hole 2 is arranged at the point at which the punt 70 meets the wall of the base. Likewise, the slot 65 preferably begins at the point at which the punt 70 meets the wall of the base. The resting base 85 is configured to rest on the flat surface 80 when the glasses are stacked.
(27) It should be noted that while the glasses can be stacked right-side up or upside down, it is preferred that the glasses are stacked upside down so that residual washing/rinsing liquid that collects in the moat 75 drains vial hole 2 or slot 65.
(28) While presently preferred embodiments have been described for purposes of the disclosure, numerous changes to the arrangement of the apparatus' parts can be made by those skilled in the art. Such changes are encompassed within the spirit of the invention as defined by the appended claims.
