Abstract
Description
Technical Field
[0001] This utility model relates to the field of biodegradable paper cup technology, and in particular to a biodegradable paper cup with double-layer heat insulation and spill prevention. Background Technology
[0002] Paper cups, as a convenient disposable beverage container, are widely used in many scenarios such as daily life, catering industry, and office. Whether it is buying soy milk or coffee at breakfast shops or providing drinks for participants at conferences, paper cups have become the first choice due to their convenience and hygiene. According to data from market research institutions, the annual consumption of paper cups worldwide has continued to grow in recent years, and the huge market demand has enabled the paper cup industry to continue to develop and expand.
[0003] Most paper cups currently available use a single-layer structure and lack effective heat insulation. When hot drinks are poured into them, heat is quickly transferred from the beverage to the surface of the cup, making it easy for users to get burned when they hold them. In daily life, paper cups are inevitably subjected to various external impacts. Because paper cups lack a cushioning structure, the impact force acts directly on the cup body, causing the cup body to crack, deform, or be damaged. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a biodegradable paper cup with double-layer heat insulation and spill prevention.
[0005] This utility model is achieved by the following technical solution: a biodegradable paper cup with double-layer heat insulation and spill prevention, including a main body, a buffer mechanism is provided inside the main body, and a protective mechanism is provided on the surface of the main body;
[0006] The main structure includes a cup body, and a heat insulation sleeve is provided inside the cup body.
[0007] As a further improvement to the above solution, the heat insulation sleeve is fixedly connected to the inner wall of the cup.
[0008] Through the above technical solution, the main structure is designed, and the heat insulation sleeve and the cup body are set in the main structure. The heat insulation sleeve is fixedly connected to the inner wall of the cup body, which can effectively block the heat of the beverage from being transferred to the surface of the cup body, reduce the risk of the user being burned when holding the paper cup, and improve the safety of holding the paper cup containing hot beverage.
[0009] As a further improvement to the above solution, the buffer mechanism includes a first buffer pad, a first buffer shaft fixedly connected to the top of the first buffer pad, a second buffer shaft sleeved inside the first buffer shaft, the second buffer shaft extending to the top of the first buffer shaft, and a second buffer pad fixedly connected to the top of the second buffer shaft.
[0010] As a further improvement to the above solution, the bottom of the first buffer pad is fixedly connected to the bottom of the inner wall of the cup, and the second buffer pad is fixedly connected to the inner wall of the cup.
[0011] Through the above technical solution and the buffer mechanism, when the paper cup is subjected to external impact, the first and second buffer pads can absorb part of the impact force. At the same time, the first and second buffer shafts can play a role in buffering and shock absorption, reducing the direct impact of the impact force on the cup body, reducing the possibility of the cup body breaking or being damaged, thereby better protecting the beverage inside the cup, reducing the risk of beverage spillage, and extending the service life of the paper cup.
[0012] As a further improvement to the above solution, the protective mechanism includes a first protective ring, a first protective shaft fixedly connected to the bottom of the first protective ring, a protective plate sleeved on the surface of the first protective shaft, a second protective shaft sleeved on the side of the protective plate away from the first protective shaft, and a second protective ring fixedly connected to the bottom of the second protective shaft.
[0013] As a further improvement to the above solution, the first protective ring and the second protective ring are symmetrically distributed through a protective plate, and both the first protective ring and the second protective ring are sleeved on the surface of the cup body.
[0014] Through the above technical solution and the protective mechanism, when the beverage is overfilled or the paper cup shakes, the first and second protective rings can prevent the beverage from overflowing to the outside of the cup, thus preventing spillage. The protective plate also allows the protective rings to have some room to move relative to the cup, improving the portability and reliability of the paper cup.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This utility model, through its main structure, incorporates a heat-insulating sleeve and a cup body. The heat-insulating sleeve is fixedly connected to the inner wall of the cup, effectively preventing heat transfer from the beverage to the cup surface. This reduces the risk of burns when the user holds the paper cup and improves safety when holding a paper cup containing hot drinks. The buffer mechanism allows the first and second buffer pads to absorb some of the impact force when the paper cup is subjected to external force. Simultaneously, the first and second buffer shafts provide cushioning and shock absorption, reducing the direct impact on the cup body and lowering the possibility of breakage or damage. This better protects the beverage inside, reduces the risk of spillage, and extends the lifespan of the paper cup. Furthermore, the protective mechanism prevents beverages from overflowing when the cup is overfilled or when it shakes. The protective plate allows the protective rings some room to move relative to the cup body, improving the portability and reliability of the paper cup. Attached Figure Description
