Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic straws, in particular to an environmentally friendly and easily degradable paper-plastic straw. Background Art

[0002] A straw is a cylindrical piece. Its main function is to drink beverages from a cup. It is also used to suck the marrow of some cooked animal long bones. The straw uses the principle of atmospheric pressure. When using it, some air is sucked away through the straw, which will cause the pressure inside the tube to decrease. In order to balance the air pressure, the atmospheric pressure will force the liquid in the tube to rise. When you stop inhaling, the liquid in the tube will drop and the pressure will return to balance.

[0003] At present, all the straws on the market are made of plastic materials. Plastic materials are easy to release toxins to pollute the environment, are difficult to recycle and reuse, are difficult to handle after recycling and decomposition, and have huge recycling costs. As a result, they have caused serious damage to global environmental protection for many years. Some drinks contain inedible parts, and the solid debris, pulp, tea leaves, etc. in the drinks cannot be blocked. For example, lemon seeds in lemonade are easily sucked into the mouth, affecting the drinking experience. Large solid particles may clog the straw, causing the straw to be unable to be used normally and requiring frequent cleaning or replacement. In response to the above problems, an environmentally friendly and decomposable paper-plastic straw is proposed to solve them. Utility Model Content

DETAILED DESCRIPTION

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figure 1-5 As shown, an environmentally friendly and easily degradable paper-plastic straw comprises a first straw 1, a second straw 3 and a third straw 6. A connecting sleeve 2 is fixedly connected to the bottom of the first straw 1. The cross section of the connecting sleeve 2 is a cone that is wide at the top and narrow at the bottom. Such a design facilitates the smooth insertion of the second straw 3 into the first straw 1, and stabilizes the connection between the two tubes through a gradually narrowing structure, thereby reducing the loosening or falling off phenomenon that may occur during use. The upper end of the second straw 3 is sleeved inside the first straw 1, and the outer side of the upper end of the second straw 3 is fixedly connected to a limiting ring 4. A grooved tube 5 is fixedly connected to the top of the first straw 1. The design of the grooved tube 5 allows the third straw 6 to rotate, thereby improving the user experience. The left end of the third straw 6 is fixedly connected to the upper end of the grooved tube 5. A blocking component 7 is inserted into the right side of the third straw 6. The blocking component 7 is used to block solid particles or ice cubes in the beverage to prevent them from entering the straw and causing blockage or discomfort when drinking. A cross bar 8 is inserted into the lower end of the first straw 1, and a pointed portion 9 is obliquely cut at the bottom of the first straw 1.

[0025] Specifically, the blocking component 7 includes a pipe clamp 701, one side of which is fixedly connected to a sleeve 702, the sleeve 702 is inserted into the inside of the third suction tube 6, and a clamping groove 703 is formed between the inner side of the pipe clamp 701 and the outer periphery of the sleeve 702, and the clamping groove 703 facilitates disassembly and installation when cleaning or replacing the blocking component 7.

[0026] Specifically, a connecting column 704 is provided inside the sleeve 702, and at least six groups of blocking plates 705 are fixedly connected to the outside of the connecting column 704. The connecting column 704 is fixedly connected to the inner wall of the sleeve 702 through the blocking plates 705. The design of the blocking plates 705 can increase the blocking effect while maintaining sufficient circulation space to ensure the smooth flow of beverages.

[0027] Preferably, the first straw 1, the second straw 3, the third straw 6 and the grooved tube 5 are composed of a base paper layer 10, a paper coating 11, an appearance layer 12 and a wear-resistant layer 13. The paper coating 11 is coated on the inner side of the base paper layer 10, the appearance layer 12 is arranged on the outer side of the base paper layer 10, and the outer side of the appearance layer 12 is fixedly connected with the wear-resistant layer 13. The appearance layer 12 can be printed with various patterns, logos and texts to make the straws more attractive. The paper coating 11 is made of food-grade safe paper material and may be specially treated to enhance its waterproof performance and durability. The base paper layer 10 provides structural support and waterproof function for the straw. The wear-resistant layer 13 can improve the wear resistance of the straw and increase the service life of the straw.

[0028] Preferably, the diameter of the first straw 1 and the third straw 6 is the same, and the diameter is 6 mm to 12 mm, and the wall thickness is between 0.2 mm and 1 mm. The outer diameter of the second straw 3 is the same as the inner diameter of the bottom end of the connecting sleeve 2. The above size design not only ensures the strength of the straw, but also makes the straw light and easy to use, and at the same time adapts to the usage habits of different groups of people.

[0029] It is worth noting that the first straw 1 , the second straw 3 , the third straw 6 and the grooved tube 5 are made of natural materials such as paper, bamboo or straw. The degradable materials are not only environmentally friendly, but also more in line with the concept of sustainable development.

[0030] Specifically, the first straw 1, the grooved tube 5 and the third straw 6 are an integrally formed structure, which not only enhances the structural strength of the straw, but also simplifies the production process and improves production efficiency.

[0031] Working principle: The cross bar 8 arranged inside the second straw 3 can prevent larger solid particles from entering the second straw 3, improving the drinking experience and avoiding interference from foreign objects, thereby improving the purity and taste of the beverage. The gap formed between the blocking plates 705 allows the liquid to pass smoothly, and the solid debris, pulp, and tea leaves are blocked inside the third straw 6, ensuring that the taste and quality of the beverage are not disturbed, and the solid debris, pulp, and tea leaves are retained inside the third straw 6. The straw can be pulled out and the inedible part can be discharged by blowing, further reducing the inedible part in the cup and improving the drinking experience.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
