DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Embodiment 1: Please refer to Figures 1-4. The utility model provides a technical solution: a scalding-proof double-layer paper cup. Traditional paper cups dissipate heat quickly during use. Hot water poured into the paper cup has a short heat preservation time. At the same time, it is easy to burn hands during use, which brings inconvenience to people. The paper cup comprises a base layer 1, a paper cup base 3 and a waterproof glue 13; the base layer 1 is fixedly connected to the paper cup base 3 through the waterproof glue 13, the top of the base layer 1 is fixedly connected with a roll 2, the base layer 1, the base layer 1 also includes coated paper 4, the outer side of the coated paper 4 is fixedly connected to the inner side of the base layer 1, the outer side of the base layer 1 is fixedly connected with aluminum foil 6, the outer side of the aluminum foil 6 is fixedly connected with a first heat-insulating glue 7, the outer side of the first heat-insulating glue 7 is fixedly connected with a first air-insulating layer 8, and the outer side of the first air-insulating layer 8 is fixedly connected There is a second thermal insulation glue 9, the outer side of the second thermal insulation glue 9 is fixedly connected with a second insulating layer 10, the outer side of the second insulating layer 10 is fixedly connected with an indentation bulging layer 11, the outer surface of the indentation bulging layer 11 is convex, the inner side of the coated paper 4 and the outer side of the indentation bulging layer 11 are fixedly connected with a waterproof layer 5, and the tightness of the connection between the first insulating layer 8 and the second insulating layer 10 is greatly enhanced through the double layer of the first thermal insulation glue 7 and the second thermal insulation glue 9, so that the paper cup has a better heat preservation and anti-scalding experience during use, and the heat preservation time after hot water is poured into the paper cup is increased. At the same time, the indentation bulging layer 11 is made of kraft paper material, and the convex design on its surface not only enhances the hardness of the outer surface of the paper cup, but also prevents the paper cup from falling off during use, and has high practicality.

As shown in Figures 1 and 3, the first heat-insulating glue 7, the second heat-insulating glue 9 and the waterproof glue 13 are all made of acrylic glue material, the first insulation layer 8 and the second insulation layer 10 are both made of corrugated material, and the base layer 1 is made of high-density virgin pulp material, which is suitable for bonding under high temperature, high pressure and various harsh environments. It can be used for a long time at a temperature above 200°C, and the maximum temperature can reach 280°C. At the same time, the acrylic glue has strong adhesion and high viscosity, and can firmly bond various materials. It can firmly connect the first insulation layer 8 and the second insulation layer 10, which greatly improves the heat insulation and waterproof properties of the paper cup. At the same time, the first insulation layer 8 and the second insulation layer 10 are both made of corrugated paper material. It should be noted that the interior of the corrugated paper is generally a honeycomb hollow setting. By setting the first insulation layer 8 and the second insulation layer 10, it not only plays a role in keeping the water in the paper cup warm, but also greatly reduces the internal temperature from being transferred to the user's hands through the gaps between the corrugated papers, thereby preventing the user from getting hot during use.

As shown in Figures 1 and 2, a support layer 12 is fixedly connected to the top of the paper cup base 3, and the upper surface of the support layer 12 is fixedly connected to the bottom of the base layer 1. The indentation bulging layer 11 and the support layer 12 are both made of kraft paper material. Kraft paper is a relatively thick and hard paper product with a granular texture on the surface, which looks like leather, hence the name. This material improves the hardness of the raised part of the surface of the indentation bulging layer 11, improves the friction of the paper cup surface, prevents the paper cup from falling off during use, and can further prevent burns.

As shown in Figures 2 and 4, a support ring 14 is installed on the inner wall of the paper cup base 3. The support ring 14 is made of polyethylene material. Polyethylene is odorless and non-toxic, has excellent mechanical properties and high ductility and strength, thereby enhancing the support and stability of the paper cup base 3. At the same time, it has good chemical resistance and can resist the erosion of chemical substances such as acids, alkalis, and solvents, so that even if the paper cup base melts, it can be supported by the support ring 14, and it is applicable to a wide range of environments. In addition, polyethylene also has good heat resistance and weather resistance, and can maintain stable performance under high temperature and harsh environments, so that when the user lifts it from the bottom of the paper cup, it can also prevent scalding, thereby improving the user's experience.

The working principle is: the utility model adopts the first thermal insulation glue 7 and the second thermal insulation glue 9 and the first insulation layer 8 and the second insulation layer 10 for double-layer insulation and heat insulation, so that the paper cup has a better heat preservation and scalding experience during use. The first thermal insulation glue 7 and the second thermal insulation glue 9 are both made of acrylic glue material, which has good thermal insulation and waterproof properties. It is suitable for bonding under high temperature, high pressure and various harsh environments, can be used for a long time at a temperature above 200°C, and the highest temperature can reach 280°C. At the same time, the acrylic glue has strong adhesion and high viscosity, can firmly bond various materials, and can firmly connect the first insulation layer 8 and the second insulation layer 10, which greatly improves the heat insulation and waterproof properties of the paper cup. At the same time, the first insulation layer 8 and the second insulation layer 10 are both made of corrugated paper materials. It should be noted that the interior of the corrugated paper is generally a honeycomb hollow setting. By setting the first insulation layer 8 and the second insulation layer 10, it not only plays a role in heat preservation of the water in the paper cup, but also greatly reduces the internal temperature from being transmitted to the user's hands through the gaps between the corrugated papers, thereby preventing the user from getting hot during use.

The indentation bulging layer 11 and the support layer 12 are both made of kraft paper, which is a relatively thick and hard paper product with a granular texture on the surface, which looks like leather, hence the name. Kraft paper is usually used to make book covers, luggage packaging, album covers and outdoor billboards, etc. It has good toughness and water resistance and can effectively protect the packaged items, thereby increasing the hardness of the raised part of the surface of the indentation bulging layer 11 and the friction of the surface of the paper cup, preventing the problem of the paper cup falling off during use, and further preventing scalding.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
