Description

Technical Field

[0001] The utility model relates to the technical field of straw manufacturing, in particular to a temperature-resistant PLA plastic straw. Background Art

[0002] Straw manufacturing technology primarily involves material selection, extrusion molding, cooling and shaping, cutting, and quality inspection. These processes enable the production of straws that meet hygiene standards. Heat-resistant PLA plastic straws are primarily made of polylactic acid (PLA), which offers excellent mechanical properties and transparency. Furthermore, they can naturally decompose under specific conditions after disposal, reducing environmental pollution.

[0003] In existing technology, some straws often fall into the cup when in use due to the cup being too high. The user then has to laboriously reach into the cup to remove the straw, which is not only unhygienic but also easily stains their hands. If the liquid in the cup is hot, the user may be burned when trying to remove the straw, significantly reducing the user experience. Therefore, a heat-resistant PLA plastic straw has been proposed to address this issue. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a temperature-resistant PLA plastic straw, which aims to improve the problem in the existing technology that some straws often fall into the inside of the cup when in use because the height of the cup is too high, greatly reducing the customer's usage experience.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 1 to 2 The utility model provides an embodiment: a heat-resistant PLA plastic straw, including a tube body 1, which is the main part of the straw. The material of the tube body 1 is polylactic acid PLA, and polylactic acid (PLA) is used as the material. PLA is a biodegradable thermoplastic aliphatic polyester made from renewable resources such as corn starch. PLA is chosen as the material because it has good mechanical properties and transparency. At the same time, it can be naturally decomposed under specific conditions after being discarded, reducing environmental pollution. The top end of the outer tube body 1 is fixedly connected with a mouthpiece 2. The design of the mouthpiece 2 takes into account the user's comfort and hygiene needs. At the same time, it has high strength itself, which effectively prevents customers who like to bite the straw and increases the bite resistance. The outer sleeve of the tube body 1 is provided with a ring 3. The ring 3 here allows the user to fix the position of the tube body 1 through the ring 3 to prevent the tube body 1 from accidentally sliding or falling off during use.

[0027] A material layer is fixedly connected to the outside of the inner wall of the tube body 1, and the material layer includes a heat-resistant layer 4. The outside of the heat-resistant layer 4 is fixedly connected to the outside of the inner wall of the tube body 1. The material of the heat-resistant layer 4 is an aluminum-silicon-carbon composite material. This material has extremely high heat resistance and thermal conductivity, and can effectively isolate the influence of high-temperature liquid on other internal layers, ensuring that the straw will not deform or release harmful substances when it comes into contact with hot drinks. A lightweight layer 5 is fixedly connected to the inside of the heat-resistant layer 4. The upper and lower ends of the lightweight layer 5 are fixedly connected to the inner wall of the tube body 1. The material of the lightweight layer 5 is a carbon fiber reinforced composite material. This material maintains the overall lightness of the straw. A buffer layer 6 is fixedly connected to the inside of the lightweight layer 5. The upper and lower ends of the buffer layer 6 are fixedly connected to the inner wall of the tube body 1. The material of the buffer layer 6 is microporous polyurethane foam. The main function of this material is to absorb impact force and prevent internal damage due to external force.

[0028] An antibacterial layer 7 is fixedly connected to the inner side of the buffer layer 6. The upper and lower ends of the antibacterial layer 7 are fixedly connected to the inner wall of the tube body 1. The antibacterial layer 7 is made of silver-loaded antibacterial plastic. This material has a certain antibacterial effect, effectively preventing the growth of bacteria. A safety layer 8 is fixedly connected to the inner side of the antibacterial layer 7. The upper and lower ends of the safety layer 8 are fixedly connected to the inner wall of the tube body 1. The safety layer 8 is made of medical-grade silicone, which is a relatively soft material and improves the customer experience. The above-mentioned multiple material layers improve the service life of this straw and the customer's comfort experience in many aspects.

[0029] Working Principle: This heat-resistant PLA plastic straw utilizes a multi-layered design, significantly enhancing its lifespan and user experience. The polylactic acid (PLA) used as the material for the tube body 1 not only possesses excellent mechanical properties and transparency but also naturally degrades under certain conditions, reducing environmental pollution. The design of the mouthpiece 2 and ring 3 enhances user comfort and convenience, preventing the straw from slipping or falling off during use.

[0030] The multi-layer material layers on the outside of the inner wall further optimize the performance of the straw: the temperature-resistant layer 4 composed of aluminum-silicon-carbon composite material effectively isolates the influence of high-temperature liquid, prevents deformation and the release of harmful substances; the lightweight layer 5 of carbon fiber reinforced composite material maintains the overall lightness of the straw; the microporous polyurethane foam buffer layer 6 absorbs impact and prevents internal damage; the silver-loaded antibacterial plastic antibacterial layer 7 inhibits bacterial growth; the medical-grade silicone safety layer 8 provides a soft touch, improving the user experience.

[0031] This multi-layered structural design enables the straw to perform excellently in terms of heat resistance, antibacterial resistance, and impact resistance, while ensuring comfort and safety of use and extending the service life of the straw.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
