Description

Technical Field

[0001] The utility model relates to a cup cover, in particular to a cup cover with a composite structure. Background Art

[0002] The cup lid is an important part of the water cup. Currently, the cup body of the water cup is generally made of stainless steel, glass, or plastic. Many people choose glass or stainless steel, which are more resistant to high temperatures and healthier and safer to use than plastic. Since the cup lid needs to have a threaded structure, many stainless steel thermos cups and glass thermos cups currently have lids made of plastic. When plastic comes into contact with water, it not only has a strong smell, but is also less safe than stainless steel and glass. Therefore, there is an urgent need for a cup lid structure composited with materials such as stainless steel. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a cup cover with a composite structure.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a composite structure cup cover, including an inner tube and an outer tube sleeved outside the inner tube, the upper and lower edges of the inner tube are bent outwards relative to each other to form outer flanges, the inner tube is stamped from stainless steel, and the upper and lower outer flanges respectively wrap the upper and lower edges of the outer tube.

[0005] Furthermore, the outer cylinder is made of plastic injection molding, and one side of the top of the outer cylinder is rotatably connected to an upper cover that can cover the inner cylinder and the upper end opening of the outer cylinder through a hinge structure.

[0006] Furthermore, a horizontal partition is arranged in the inner tube, the partition and the inner tube are integrally stamped from stainless steel, and a plurality of water outlet holes are opened on one side of the surface of the partition.

[0007] Furthermore, an outer side wall of the outer cylinder is provided with an external thread structure.

[0008] Furthermore, a rubber sealing ring is sleeved on the bottom of the outer cylinder.

[0009] Furthermore, a ventilation hole is provided on the surface of the partition opposite to the water outlet hole.

[0010] The upper and lower edges of the inner cylinder of the utility model are respectively bent outwards relative to each other to form outer flanges, and the inner cylinder is stamped from stainless steel, so that the upper and lower outer flanges respectively wrap the upper and lower edges of the outer cylinder, so that the inside of the cup cover is equivalent to wrapping a layer of stainless steel in contact with water, while the outside can be made of plastic and other structures, which can effectively isolate the internal water from contacting the external plastic material and effectively prevent the water from containing the plastic taste. Moreover, this composite structure is lighter in weight and more convenient to carry than a cup cover made of stainless steel as a whole, which not only effectively saves costs, but also the composite structure of plastic and stainless steel has a better thermal insulation effect.
