DETAILED DESCRIPTION

[0027] The application will be further described in detail below in combination with the drawings and examples.

[0028] The application discloses a paper cup with good heat preservation effect. Figure 1 The paper cup with good heat preservation effect comprises a cup body 1, the inner wall of the cup body 1 is fixed with a first heat preservation layer 2, and the first waterproof layer 3 is made of polyethylene material. The inner wall of the first heat preservation layer 2 is fixed with a waterproof layer 3, and the waterproof layer 3 is a waterproof film layer. The outer wall of the cup body 1 is fixed with a heat preservation and insulation layer 4, the heat preservation and insulation layer 4 is made of polyurethane foaming material, and the cross section of the heat preservation and insulation layer 4 is in a honeycomb shape 61. The paper cup with good heat preservation effect further comprises single-layer corrugated paper 5, and the single-layer corrugated paper 5 is attached to the outer wall of the heat preservation and insulation layer 4.

[0029] The paper cup with good heat preservation effect further comprises a cup cover 7, and the cup cover 7 is arranged on the top of the cup body 1. An insertion slot 62 is formed in the cup cover 7, the insertion slot 62 is used for inserting a straw, the cup cover 7 is fixed with a sliding rail 66, the cup cover 7 is slidably connected with a push piece 63, the push piece 63 slides along the length direction of the sliding rail 66, and the insertion slot 62 is covered or exposed when the push piece 63 slides.
