Thermal insulation cup with a tilted neck

Abstract

A thermal insulation cup with a tilted neck includes an outer case and an inner tank arranged inside the outer case. The outer case includes a first cup wall, a second cup wall, and a case bottom that together define a cavity with an open end. The end of the first cup wall has a less height than that of the end of the second cup wall. The first cup wall gradually tilts inward in the direction from the bottom to the end. The second cup wall gradually tilts inward in the direction from the bottom to the end. The inner tank includes a drinking port, a first inner wall, a second inner wall, and a bottom that together define a cavity with an open end. The end of the first inner wall has a less height than that of the second inner wall. The first inner wall gradually tilts inward in the direction from the bottom to the end, and the second inner wall gradually tilts inward in the direction from the bottom to the end. The ends of the outer case and the inner tank respectively define an opening and a drinking port that are inclined to the same side. The opening is welded and fixed to the lower part of the drinking port.
