Dual chamber drinking vessel

Abstract

A dual chamber drinking vessel includes a cup chamber positioned adjacent to an angled chamber. The cup chamber includes a cup upper portion and a cup lower portion. The angled chamber includes an angled chamber upper portion and an angled chamber lower portion. The cup upper portion is joined to the angled chamber upper portion by a bridge. The dual chamber drinking vessel is configured to allow different liquids to be received within the cup chamber and angled chamber without mixing the liquids until the vessel is tilted to elevate the angled chamber relative to the cup chamber. The angled chamber includes an outer wall portion and an inner wall portion. The inner wall portion extends at an angle from the bridge and meets the outer wall portion at an angle configured to enhance the mixing of the second liquid with the first liquid.

         1 . A dual chamber drinking vessel, comprising:
 a cup chamber including a cup upper portion and a cup lower portion; and   an angled chamber including an angled chamber upper portion and an angled chamber lower portion having an inclined bottom surface, wherein the cup upper portion is joined to the angled chamber upper portion.   
     
     
         2 . The dual chamber drinking vessel of  claim 1 , wherein the cup upper portion is joined to the angled chamber upper portion by a common rim and a bridge. 
     
     
         3 . The dual chamber drinking vessel of  claim 2 , wherein the bridge is at a position lower than the common top lip. 
     
     
         4 . The dual chamber drinking vessel of  claim 1 , wherein the cup chamber is configured to receive a first liquid, and the angled chamber is configured to receive a second liquid, wherein tilting of the vessel such that the angled chamber is elevated relative to the cup chamber causes the second liquid to enter the cup chamber and to mix with the first liquid. 
     
     
         5 . The dual chamber drinking vessel of  claim 1 , wherein the cup chamber has a liquid-volume-capacity and the coupled chamber has a liquid volume capacity, and a ratio of the liquid-volume-capacity of the cup chamber to liquid-volume-capacity of the angled chamber is about 2:1. 
     
     
         6 . A dual chamber drinking vessel, comprising:
 a vertical axis;   a cup chamber including a cup upper portion and a cup lower portion; and   an angled chamber including an angled chamber upper portion and an angled chamber lower portion, wherein the cup chamber is positioned adjacent to the angled chamber, and the cup upper portion is joined to the angled chamber upper portion by a bridge;   wherein the cup chamber is configured to receive a first liquid, and the angled chamber is configured to receive a second liquid, and wherein tilting of the vessel such that the angled chamber is elevated relative to the cup chamber causes the second liquid to enter the cup chamber and to mix with the first liquid.   
     
     
         7 . The dual chamber drinking vessel of  claim 6 , wherein the angled chamber further comprises an outer wall portion and an inner wall portion, and wherein the inner wall portion extends at an angle to the vertical axis of 36 degrees to 41 degrees. 
     
     
         8 . The dual chamber drinking vessel of  claim 6 , wherein the liquid-volume-capacity ratio of the cup chamber to the angled chamber is about 2:1. 
     
     
         9 . The dual chamber drinking vessel of  claim 6 , wherein the cup chamber has a liquid-volume-capacity of about 1.0 to 4.0 ounces and the angled chamber has a liquid-volume-capacity of about 0.50 to 2.0 ounces. 
     
     
         10 . The dual chamber drinking vessel of  claim 6 , wherein the cup chamber and the angled chamber are configured to allow a plurality of dual chamber drinking vessels to be stacked together. 
     
     
         11 . The dual chamber drinking vessel of  claim 6 , wherein the cup upper portion is joined to the angled chamber upper portion by a common rim. 
     
     
         12 . The dual chamber drinking vessel of  claim 11 , wherein the angled chamber further comprises an outer wall portion and an inner wall portion, and the outer wall portion extends inward from the common rim and meets the inner wall portion at an angle of about 20 degrees to about 40 degrees. 
     
     
         13 . The dual chamber drinking vessel of  claim 11 , wherein the bridge is positioned at a distance of about 0.10 to 0.50 inches below the common rim. 
     
     
         14 . The dual chamber drinking vessel of  claim 11 , further comprising a cup chamber opening for accessing an interior cup space, and an angled chamber opening for accessing an interior angled space, wherein the common rim joins the cup chamber opening to the angled chamber opening, creating a shared vessel opening. 
     
     
         15 . A dual chamber drinking vessel, comprising:
 a cup chamber including a cup upper portion and a cup lower portion; and   an angled chamber including an angled chamber upper portion and an angled chamber lower portion,   wherein the cup chamber is positioned adjacent to the angled chamber, and the cup upper portion is joined to the angled chamber upper portion by a bridge;   wherein the cup chamber is configured to receive a first liquid, and the angled chamber is configured to receive a second liquid, wherein tilting of the vessel such that the angled chamber is elevated relative to the cup chamber causes the second liquid to enter the cup chamber and to mix with the first liquid; and   wherein the angled chamber further comprises an outer wall portion and an inner wall portion, and the inner wall portion extends at an angle from the bridge and meets the outer wall portion at an angle configured to enhance the mixing of the second liquid with the first liquid.   
     
     
         16 . The dual chamber drinking vessel of  claim 15 , wherein the inner wall portion meets the outer wall portion at an angle ranging from about 20 degrees to about 40 degrees. 
     
     
         17 . The dual chamber drinking vessel of  claim 15 , wherein the cup chamber and the angled chamber are configured to allow a plurality of dual chamber drinking vessels to be stacked together. 
     
     
         18 . The dual chamber drinking vessel of  claim 15 , wherein the liquid-volume-capacity ratio of the cup chamber to the angled chamber is about 2:1. 
     
     
         19 . The dual chamber drinking vessel of  claim 15  further comprising an overall rim joining the cup upper portion to the angled chamber upper portion, wherein the overall rim is ellipse shaped. 
     
     
         20 . The dual chamber drinking vessel of  claim 19 , wherein the bridge is positioned at a distance of about 0.10 to about 0.50 inches below the common rim.
