Single-use wine glass

Abstract

Wine glasses and wine glass assemblies with improved durability. In some examples, wine glasses/assemblies include a vessel, a stem, and a base that can be assembled together. In some examples, one or more annular protruding ribs can provide strength to the wine glasses or wine glass assemblies while reducing the amount of material required to manufacture the wine glass/assembly.

1 . A wine glass comprising:
 a liquid vessel, the liquid vessel having an open top and a closed bottom and comprising a bottom wall and a side wall integral with the bottom wall, each of the bottom wall and the side wall having an inner surface and an outer surface, the inner surfaces of the bottom wall and the side wall defining an interior volume for containing liquid;   wherein the outer surface of the side wall projects outwardly in at least one rib surrounding a perimeter of a horizontal cross-section of the vessel between the top of the vessel and the bottom of the vessel; and   wherein the outer surface of the bottom wall includes an upwardly projecting recess; and   wherein the inner surface of the bottom wall includes an upward projection.   
     
     
         2 . The wine glass of  claim 1 , wherein the outer surface projects outwardly in at least two of the ribs, the at least two ribs being separated vertically from each other. 
     
     
         3 . (canceled) 
     
     
         4 . The wine glass of  claim 1 , wherein a width of the vessel narrows from the open top to the closed bottom. 
     
     
         5 . The wine glass of  claim 1 , wherein the at least one rib comprises a hollow portion. 
     
     
         6 . The wine glass of  claim 5 , wherein the hollow portion is disposed between the inner surface and the outer surface. 
     
     
         7 - 15 . (canceled) 
     
     
         16 . The wine glass of  claim 1 , wherein the at least one rib is manufactured integrally with the rest of the liquid vessel. 
     
     
         17 . (canceled) 
     
     
         18 . A wine glass assembly comprising:
 a liquid vessel comprising a first mating feature;   a base comprising a second mating feature; and   a stem, the stem comprising a vertical axis, a first end having a third mating feature, and a second end opposite the first end on the vertical axis, the stem further comprising a fourth mating feature, the third and fourth mating features having identical configurations such that each of the third and fourth mating features is complementary to the first and second mating features;   wherein the liquid vessel has an open top and a closed bottom and is defined by a side wall and a bottom wall integral with the side wall, each of the bottom wall and the side wall having an inner surface and an outer surface, the inner surfaces of the bottom wall and the side wall defining an interior volume for containing liquid;   wherein the outer surface projects outwardly in at least one rib surrounding a perimeter of a horizontal cross-section of the vessel between the top of the vessel and the bottom of the vessel; and   wherein the first mating feature comprises an upwardly projecting recess in the outer surface of the bottom wall and an upward projection of the inner surface of the bottom wall.   
     
     
         19 . The wine glass assembly of  claim 18 , wherein the first and second mating features are female mating features and the third and fourth mating features are male mating features. 
     
     
         20 . The wine glass assembly of  claim 18 , wherein the second mating feature is a downward projecting recess in a top surface of the base, and the stem is symmetrical about a horizontal axis of the stem that bisects the stem and is perpendicular to the vertical axis. 
     
     
         21 . The wine glass of  claim 1 , wherein an upper portion of the wall extending from the at least one rib to the open top is thickest at the open top. 
     
     
         22 . (canceled) 
     
     
         23 . The wine glass assembly of  claim 18 , wherein an upper portion of the wall extending from the at least one rib to the open top is thickest at the open top. 
     
     
         24 . (canceled) 
     
     
         25 . The wine glass of  claim 5 , wherein the hollow portion is in open communication with the liquid vessel. 
     
     
         26 . The wine glass of  claim 1 , wherein the upwardly projecting recess and the upward projection define a mating feature. 
     
     
         27 . The wine glass of  claim 1 , wherein a portion of the inner surface of the bottom wall is flat. 
     
     
         28 . The wine glass of  claim 1 , wherein a portion of the outer surface of the bottom wall is flat. 
     
     
         29 . The wine glass of  claim 1 , wherein a portion of the inner surface of the bottom wall is flat, and wherein a portion of the outer surface of the bottom wall is flat. 
     
     
         30 . The wine glass assembly of  claim 18 , wherein a portion of the inner surface of the bottom wall is flat. 
     
     
         31 . The wine glass assembly of  claim 18 , wherein a portion of the outer surface of the bottom wall is flat. 
     
     
         32 . The wine glass assembly of  claim 18 , wherein a portion of the inner surface of the bottom wall is flat, and wherein a portion of the outer surface of the bottom wall is flat.
