There is only one liner plate between two adjacent ribs, with the left and right sides respectively connected to the adjacent ribs. The inner end of the liner plate is also connected to the inner cup cylinder and the outer end is also connected to the outer cup cylinder. The liner plate and the bottom cover are not located on the same horizontal plane. The top of the inner cup cylinder has an outward and downward rolled edge that surrounds the top of the outer cup cylinder.

[0005] The present invention is further configured such that the liner is located at one-third or two-thirds of the height of the outer cylinder of the cup.

[0006] The present invention is further configured such that: one half of the liner is located at one-third of the height of the outer cylinder of the cup, and the other half of the liner is located at two-thirds of the height of the outer cylinder of the cup.

[0007] The present invention is further configured such that the heights between two adjacent lining plates are not equal.

[0008] The present invention is further configured such that: the outer cylinder of the cup and the inner cylinder of the cup are arranged on the same axis; the rib extends radially along the outer cylinder of the cup; and the included angle between adjacent ribs is equal.

[0009] The present invention is further configured such that: the rib plate is an integral structure with the inner cylinder and the outer cylinder of the cup; the liner plate is an integral structure with the rib plate; and the edging is an integral structure with the inner cylinder of the cup.

[0010] The present invention is further configured such that the inner cylinder, outer cylinder, rib plate, liner plate and edging are all made of polypropylene material.

[0011] In summary, this utility model has the following beneficial effects:

[0012] 1. Double-layer heat insulation prevents burns and makes it easy to hold.

[0013] 2. Built-in linings at different heights enhance the lateral pressure resistance of the outer cylinder of the cup, preventing local collapse when gripping.

[0014] 3. Simple structure, enabling one-piece injection molding. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0020] Example 1

[0021] See Figures 1 to 3 As shown, the heat-resistant and heat-insulating polypropylene cup body involved in this embodiment includes an inner cup cylinder 1, a bottom cover 2 that seals the bottom opening of the inner cup cylinder 1, an outer cup cylinder 3 that surrounds the inner cup cylinder 1, and a plurality of ribs 4 that are connected to the inner cup cylinder at their inner ends and to the outer cup cylinder at their outer ends between the outer cup cylinder 3 and the inner cup cylinder 1. There is only one liner 5 between two adjacent ribs 4, which is connected to the adjacent ribs on the left and right sides respectively. The inner end of the liner 5 is also connected to the inner cup cylinder, and the outer end is also connected to the outer cup cylinder. The liner 5 and the bottom cover 2 are not located on the same horizontal plane. The top of the inner cup cylinder 1 is provided with an outward and downward rolled edge 6 that surrounds the top of the outer cup cylinder 3.

[0022] Furthermore, one half of the liner 5 is located at one-third of the height of the outer cylinder 3 of the cup, and the other half of the liner 5 is located at two-thirds of the height of the outer cylinder 3 of the cup; the heights between adjacent liner 5 are not equal.

[0023] Furthermore, the outer cylinder 3 and the inner cylinder 1 of the cup are arranged coaxially; the rib 4 extends radially along the outer cylinder 3 of the cup; and the included angle between two adjacent rib 4 is equal.
