[0004] However, although the above heat insulation layer can insulate heat, when it is made into a paper cup for use, it is bound to be made very thin, and the thickness of the heat insulation layer is positively correlated with its heat insulation effect. The thinner heat insulation layer results in a weaker heat insulation effect. Content of the Utility Model

[0005] The purpose of the utility model is to provide an antibacterial and waterproof paper cup, which solves the problem that the existing paper cup has a thin heat insulation layer, resulting in a weak heat insulation effect.

[0006] To achieve the above purpose, the utility model provides an antibacterial and waterproof paper cup, including a cup body and an outer sleeve body;

[0007] The outer sleeve body is fixedly connected to the cup body, is located outside the cup body, and forms an accommodation space with the cup body. The outer sleeve body has protruding blocks, the number of the protruding blocks is multiple, the multiple protruding blocks are respectively located on the surface wall of the outer sleeve body, and are respectively distributed in a circumferential manner along the axis center line of the outer sleeve body. The surface of the protruding blocks has multiple convex points.

[0008] Wherein, the cup body includes an antibacterial coating and a waterproof layer. The cup wall of the cup body is successively the antibacterial coating and the waterproof layer from the inside to the outside, and nano-gold is provided in the antibacterial coating.

[0009] Wherein, the cup body further includes an aluminum film, and the aluminum film is located on the side of the waterproof layer away from the antibacterial coating.

[0010] Wherein, the cup body further includes a heat insulation layer, and the heat insulation layer is located on the side of the aluminum film away from the waterproof layer. The heat insulation layer is made of honeycomb heat insulation material.

[0011] Among them, the antibacterial and waterproof paper cup further includes a protective layer, and the protective layer is located on the outer wall of the outer sleeve body.

[0012] For an antibacterial and waterproof paper cup of the present utility model, the outer sleeve body is made of a honeycomb-shaped heat-insulating material, which has a heat-insulating effect, and there is the accommodation space between the outer sleeve body and the cup body. There is air in the accommodation space, which reduces heat transfer and thus plays a heat-insulating role. Multiple protruding blocks increase the thickness of the outer sleeve body, further enhancing the heat-insulating effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0020] The first embodiment of the present application is as follows:

[0021] Please refer to Figures 1 to 4 , among which, Figure 1 It is a schematic connection diagram of the cup body 101 and the outer sleeve body 102 of the present utility model. Figure 2 It is a cross-sectional view of the cup body 101 and the outer sleeve body 102 of the present utility model. Figure 3 It is an enlarged schematic structural view of the cup body 101 of the present utility model. Figure 4It is an enlarged schematic view of the structure of the outer sleeve 102 of the present utility model. The present utility model provides an antibacterial and waterproof paper cup, which includes a cup body 101 and an outer sleeve 102. The outer sleeve 102 has a protruding block 103 and a convex point 104. The cup body 101 includes an antibacterial coating 106, a waterproof layer 107, an aluminum film 108 and a protective layer 110. Through the foregoing solution, the problem that the existing heat insulation layer 109 of the paper cup is relatively thin, resulting in weak heat insulation effect, is solved. It can be understood that the foregoing solution can also be used to solve the problem of antibacterial and waterproof materials.

[0022] For this specific embodiment, the outer sleeve 102 is fixedly connected to the cup body 101, is located outside the cup body 101, and forms an accommodation space 105 with the cup body 101. The outer sleeve 102 has a protruding block 103. The number of the protruding blocks 103 is multiple. The multiple protruding blocks 103 are respectively located on the surface wall of the outer sleeve 102 and are respectively distributed in a circumferential manner along the axis center line of the outer sleeve 102. The surface of the protruding block 103 has a plurality of convex points 104. The outer sleeve 102 is made of a honeycomb heat insulation material and is arranged outside the cup body 101. When the cup body 101 is filled with water, and there is air in the accommodation space 105 formed between the outer sleeve 102 and the cup body 101, heat transfer is reduced to play a heat insulation role. The multiple protruding blocks 103 on the surface of the outer sleeve 102 increase the thickness of the outer sleeve 102 to play a heat insulation role. The multiple convex points 104 increase the friction of the outer sleeve 102, facilitating the hand to hold it more conveniently.

[0023] Among them, the cup wall of the cup body 101 from the inside to the outside is successively the antibacterial coating 106 and the waterproof layer 107. Nano gold is provided in the antibacterial coating 106. The antibacterial coating 106 is formed by spraying a nano gold solution on the waterproof layer 107 and drying it, and has an antibacterial effect. The waterproof layer 107 is made of a composite of nano gold carbon fiber and edible pulp, which not only has good water resistance, but also has antibacterial and enhanced tensile strength effects of the paper.

[0024] Secondly, the aluminum film 108 is located on the side of the waterproof layer 107 away from the antibacterial coating 106. The aluminum film 108 is a food-grade vacuum aluminized film and has a heat insulation and heat preservation effect.

[0025] At the same time, the heat insulation layer 109 is located on the side of the aluminum film 108 away from the waterproof layer 107. The heat insulation layer 109 is made of a honeycomb heat insulation material. The heat insulation layer 109 is made of a honeycomb heat insulation material, which improves the heat insulation of the cup wall. At the same time, it can also ensure the stability of the cup wall when the paper cup is heated and prevent the cup wall from becoming soft. The outer sleeve 102 is made of the same honeycomb heat insulation material to play a double-layer heat insulation role.

[0026] In addition, the protective layer 110 is located on the outer wall of the outer sleeve 102. The protective layer 110 is made of paper, which improves the heat insulation effect and enhances the aesthetics at the same time.

[0027] When using an antibacterial and waterproof paper cup according to this embodiment, the paper cup includes, from the inside to the outside, the antibacterial coating 106, the waterproof layer 107, the aluminum film 108, the heat insulation layer 109, the outer sleeve 102, and the protective layer 110. Among them, the aluminum film 108, the heat insulation layer 109, and the outer sleeve 102 enhance the heat insulation effect, making the heat insulation effect better.

[0028] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
