Abstract

A drinking vessel has a sidewall formed of multiple structured layers. The sidewall includes an open spout and a closed base. A circumference of the side wall at the base is larger than a circumference of the side wall at the open spout to provide the drinking vessel with a lowered center of gravity than a traditional drinking vessel with the closed base narrower than the open spout. The sidewall includes multiple structured layers to form a scaffold structure.

1 . A drinking vessel comprising a sidewall formed of multiple structured layers, the sidewall comprising an open spout and a closed base, a circumference of the sidewall at the base is larger than a circumference of the sidewall at the open spout to provide the drinking vessel with a lowered center of gravity than a traditional drinking vessel with the closed base narrower than the open spout; and wherein the sidewall comprises multiple structured layers to form a scaffold structure. 
     
     
         2 . The drinking vessel of  claim 1 , wherein the scaffold structure comprises an outer shell that comes into contact with a user, an inner shell, an outer lining, an inner lining that holds content of the drinking vessel, and an air pocket insulation between the inner shell and the outer lining. 
     
     
         3 . The drinking vessel of  claim 1 , further comprising vents on the outer and inner shells of the sidewall to facilitate heat-cold air exchanges to regulate a temperature of the outer shell. 
     
     
         4 . The drinking vessel of  claim 3 , wherein the vents on the outer shell provide an uneven gripping surface to prevent slippage. 
     
     
         5 . The drinking vessel of  claim 3 , wherein the vents facilitate evaporation and drainage of water forming on the outer shell. 
     
     
         6 . The drinking vessel of  claim 1 , wherein the scaffold structure comprises an inner base and an outer base rim to double layers of the closed base, thereby increasing a surface area of the closed base. 
     
     
         7 . The drinking vessel of  claim 2 , wherein the air pocket insulation of the scaffold structure decreases a heat/cold transfer from the content of the drinking vessel to the outer shell. 
     
     
         8 . The drinking vessel of  claim 2 , wherein the air pocket insulation of the scaffold structure decreases condensation on the outer shell caused by a heat/cold exchange between the content of the drinking vessel and outside, thereby a minimizing wet slippery outer shell surface. 
     
     
         9 . The drinking vessel of  claim 2  is stackable unto a second drinking vessel. 
     
     
         10 . The drinking vessel of  claim 9 , wherein a narrow end of the scaffold structure of the drinking vessel is insertable into a wide end of a scaffold structure of the second drinking vessel to provide stacking for a compact storage. 
     
     
         11 . The drinking vessel of  claim 1  is a mug, a drinking glass, a drinking bottle, a tumbler or a bowl.
