Description

Technical Field

[0001] The utility model relates to the field of packaging, in particular to a telescopic coated degradable paper cup. Background Art

[0002] Paper cups are made of paper (white paperboard) made of chemical wood pulp through mechanical processing and bonding. They are cup-shaped. Paper cups are safe, hygienic, light and convenient, and can be used in public places, hotels and restaurants.

[0003] However, conventional paper cups are not retractable, so the capacity cannot be adjusted during use, and may not be suitable for occasions with different needs. In addition, the inner coating of conventional paper cups is polyethylene or polyethylene wax, which are plastic materials that are not easily degradable and will pollute the environment. In addition, due to the presence of the coating, conventional paper cups need to be separated during recycling, which increases the difficulty and cost of recycling.

[0004] Therefore, the utility model provides a retractable coated degradable paper cup to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and propose a retractable coated degradable paper cup.

[0007] Through the above technical solution, place paper cup No. 1 on a flat surface and then pull paper cup No. 2 upward, the connecting block and the telescopic joint will stretch upward to the required height, then the card block will be stuck in the card hole, and finally water will be poured into paper cup No. 2. Using this design, the height adjustment can be completed by simply pulling the paper cup upward and jamming the card block, which is simple and convenient to operate.

[0008] Furthermore, the second paper cup comprises a first layer, a second layer is fixedly disposed on the inner end of the first layer, and a third layer is fixedly disposed on the inner end of the second layer;

[0009] Through the above technical solution, the multi-layer structure design can improve the texture of the paper cup, increase the quality of the paper cup, enhance the user experience, and make it more attractive.

[0010] Furthermore, the first layer is made of paper pulp, and the second layer is made of corn starch;

[0011] According to the above technical solution, the first layer is made of pulp because pulp is made of plant fibers such as waste paper and bamboo and can be naturally degraded in a short time. The second layer is made of corn starch because it has good degradability and is environmentally friendly.

[0012] Furthermore, the third layer is made of polyhydroxyalkanoate;

[0013] Through the above technical solution, the third layer uses polyhydroxyalkanoate because it has good thermal stability, does not release harmful substances when used in hot water, can be degraded under suitable environmental conditions, and can also be degraded through industrial composting and soil microorganisms.

[0014] Furthermore, the inner end of the No. 2 paper cup is provided with a coating layer, and the coating layer is coated with aliphatic polyester;

[0015] Through the above technical solution, the coating layer is coated with aliphatic polyester because aliphatic polyester has good waterproof properties, which can effectively prevent the liquid inside the paper cup from penetrating to the outside of the paper cup, prevent the paper cup from deforming or leaking, and increase the service life of the paper cup. In addition, aliphatic polyester is a degradable material, which is beneficial to reducing the impact on the environment.

[0016] Furthermore, the anti-scalding pad is made of polycarbonate, and the connecting block is made of polylactic acid;

[0017] According to the above technical solution, the anti-scalding pad adopts polycarbonate because polycarbonate has good heat resistance, can withstand high temperatures, is not easy to soften or deform, and is a recyclable plastic material, which is conducive to resource recycling. The connecting block adopts polylactic acid because polylactic acid is a biodegradable plastic made from renewable resources such as plant starch, and has good water-repellent properties.

[0018] Furthermore, a cup edge is fixedly arranged at the upper end of the No. 2 paper cup, and the clamping block is clamped and arranged at the inner end of the clamping hole;

[0019] Through the above technical solution, the cup edge can effectively prevent the beverage from overflowing from the cup mouth, keep the beverage in the cup, and avoid pollution and waste. By setting the clamping block at the inner end of the clamping hole, it can ensure that the connection between the clamping block and the clamping hole is more firm and stable, and is not easy to loosen or fall off.

[0020] The utility model has the following beneficial effects:

[0021] 1. The utility model proposes a retractable coated degradable paper cup. The new coating is degradable, which reduces pollution to the environment and conforms to the concept of sustainable development. The degradable coating material can reduce the penetration of harmful substances into food and protect the health of consumers.

[0022] 2. The utility model proposes a retractable coated biodegradable paper cup. The new paper cup is retractable and has a wider range of applications. It can meet the use of different occasions and needs. In addition, the new paper cup is provided with an anti-scalding pad, which can reduce the direct feeling of contact between the hand and the hot cup and improve the comfort of the user.
