The present invention relates to a ring upper edge and a heat insulating cup having the upper edge of the ring.

At present, most commonly used cups are made of stainless steel as a two-layer structure, and the air between the two layers is extracted, so that the liquid in the cup cannot be used as a medium and the outside by the air between the two layers. Heat exchange is performed to make the liquid in the vacuum cup have good heat preservation effect. However, stainless steel liners, when used to hold acidic beverages such as lemonade, can cause users to worry about the dissolution of metal materials. Some people complain that when they drink tea or coffee, they will be distorted and unable to maintain their originality. Style.

Therefore, at present, some manufacturers are processing in the stainless steel inner tank, increasing the inner layer of the ceramic, and allowing the drink to contact the ceramic, which is not only easy to clean, but also has no problem of odor or dissolution. Unfortunately, due to the material properties of ceramics, the thickness is not easy to control, which not only makes the weight of the thermos cup increase greatly, but also makes it difficult to carry.
