Abstract

A vessel includes a lid and a container. The lid includes a main body and a brim structure. The main body is integrally surrounded by the brim structure. The brim structure from the inside out includes a first side portion, a first horizontal portion, a first inclined portion, a second inclined portion and a fifth inclined portion. The container includes a bottom, a side wall and an edge structure. The bottom is integrally surrounded by the side wall, and the side wall is integrally surrounded by the edge structure. The edge structure from the inside out includes a second side portion, a second horizontal portion, a third inclined portion, a fourth inclined portion and a sixth inclined portion. When the edge structure is engaged with the brim structure, the container is sealed by the lid.

         2 . The vessel of  claim 1 , wherein the brim structure further comprises a lid tab connected to an edge of the fifth inclined portion, and the lid tab is triangular, rectangular or semicircular. 
     
     
         3 . The vessel of  claim 2 , wherein the lid tab comprises rugged surface. 
     
     
         4 . The vessel of  claim 1 , wherein the edge structure further comprises a container tab connected to an edge of the sixth inclined portion, and the container tab is triangular, rectangular or semicircular. 
     
     
         5 . The vessel of  claim 4 , wherein the container tab comprises a rugged surface. 
     
     
         6 . The vessel of  claim 1 , wherein the bottom comprises a convex portion located at the center of the bottom, and the convex portion is circular. 
     
     
         7 . The vessel of  claim 6 , wherein the main body comprises a nose portion located at the center of the main body, the nose portion is correspondent to the convex portion of the bottom, and the nose portion is circular. 
     
     
         8 . The vessel of  claim 1 , wherein there are a first side angle between the first side portion and the first horizontal portion, a second side angle between the second side portion and the second horizontal portion, the first side angle is equal to the second side angle, and the first side angle is greater than 60 degrees and less than 90 degrees. 
     
     
         9 . The vessel of  claim 1 , wherein there are a first inclined angle between the first inclined portion and the first horizontal portion, a third inclined angle between the third inclined portion and the second horizontal portion, the first inclined angle is equal to the third inclined angle, and the first inclined angle is greater than 60 degrees and less than 90 degrees. 
     
     
         10 . The vessel of  claim 1 , wherein the second inclined angle is equal to the fourth inclined angle, and the second inclined angle is greater than 30 degrees and less than 60 degrees. 
     
     
         11 . The vessel of  claim 1 , wherein the fifth inclined angle is equal to the sixth inclined angle, and the fifth inclined angle is greater than 45 degrees and less than 90 degrees.
