Description

Technical Field

[0001] This utility model relates to the field of catering straw technology, specifically a PHA bendable straw. Background Technology

[0002] A straw is a tubular item used to sip liquid beverages or food. It is usually made of materials such as plastic, paper, or metal. One end is pointed or flat, making it easy to insert into a liquid container, while the other end has a large opening for people to suck. Straws are very convenient to use, avoiding the hygiene problems of drinking directly from the mouth, and also making the drinking process more elegant and convenient. However, with the increasing awareness of environmental protection, more and more people are beginning to pay attention to the pollution caused by straws. Traditional disposable plastic straws are often discarded after use, becoming non-biodegradable waste and causing environmental pollution.

[0003] However, the current biodegradable and environmentally friendly straws are mainly made of PLA, which cannot be degraded by home composting or in the ocean. Moreover, the temperature resistance of crystallized PLA straws is usually no more than 80℃. In high temperature and high humidity environments, the straws degrade quickly, which leads to a decrease in performance. Most of the flexible straws on the market have smooth surfaces and are easy to slip out after being inserted into a beverage cup. In addition, because the holes in the beverage cup's sealing film are almost in contact with the surface of the straw, the pressure inside the cup is relatively high when drinking, making it inconvenient to drink and reducing the practicality of biodegradable straws.

[0004] Therefore, biodegradable straws need to be improved to avoid the harsh degradation conditions, high temperature resistance, and the tendency for straws to detach from the beverage cup. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a PHA bendable straw that has the advantages of being easy to degrade, resistant to high temperatures, and not easily detached. This solves the problems of existing biodegradable straws having harsh degradation conditions and low degradation efficiency, being not resistant to high temperatures and softening when exposed to high temperatures, and having an overly smooth surface that causes them to detach after being placed in a beverage cup.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PHA bendable straw, comprising a straw, a folded tube fixedly connected to the top of the straw, a tube head fixedly connected to the right side of the folded tube, and a buckle slidably connected to the surface of the straw. The straw, the folded tube, the tube head, and the buckle are all made of PHA material.

[0007] As a preferred embodiment of this invention, ventilation strips are provided on both sides of the straw, and the inner side of the ventilation strips is fixedly connected to the surface of the buckle.

[0008] As a preferred embodiment of this utility model, a connecting sleeve is provided on the surface of the straw, a limiting plate is fixedly connected to the top of the connecting sleeve, the limiting plate is sleeved on the surface of the straw, and the bottom of the connecting sleeve is fixedly connected to the top of the buckle.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. Compared with PLA curved straws, this utility model has higher temperature resistance, reaching above 90℃, high heat sealing performance, and avoids the migration of trace substances in the straw into the liquid, resulting in higher food safety. It also features a fixed buckle to prevent the straw from slipping off, high water vapor barrier performance, and has a wider range of degradation conditions compared with biodegradable straws on the market.

[0011] 2. This utility model prevents the surface of the straw from sticking tightly to the surface of the sealing film of the beverage cup by setting a ventilation strip, thus avoiding the phenomenon that excessive pressure inside the cup affects the user's drinking efficiency.

[0012] 3. By setting a connecting sleeve and a limiting plate, this utility model can prevent the buckle from detaching from the straw after it is fully inserted into the beverage cup. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4As shown, the present invention provides a PHA bendable straw, including a straw 1, a folded tube 2 fixedly connected to the top of the straw 1, a tube head 3 fixedly connected to the right side of the folded tube 2, and a buckle 4 slidably connected to the surface of the straw 1. The straw 1, the folded tube 2, the tube head 3 and the buckle 4 are all made of PHA material.

[0020] refer to Figure 2 Both sides of the straw 1 are provided with ventilation strips 5, and the inner side of the ventilation strips 5 is fixedly connected to the surface of the buckle 4.

[0021] As a technical optimization of this utility model, by setting a ventilation strip 5, the surface of the straw 1 is prevented from sticking tightly to the surface of the sealing film of the beverage cup, thus avoiding the phenomenon that excessive pressure inside the cup affects the user's drinking efficiency.

[0022] refer to Figure 3 A connecting sleeve 6 is fitted on the surface of the straw 1. A limiting plate 7 is fixedly connected to the top of the connecting sleeve 6. The limiting plate 7 is fitted on the surface of the straw 1. The bottom of the connecting sleeve 6 is fixedly connected to the top of the buckle 4.

[0023] As a technical optimization of this utility model, by setting the connecting sleeve 6 and the limiting plate 7, the phenomenon that the buckle 4 will detach from the straw 1 after being fully inserted into the beverage cup can be avoided.

[0024] The working principle and usage process of this utility model are as follows: When in use, first insert the bottom of the PHA straw 1 into the inside of the beverage cup. After insertion, press the ventilation strip 5 inward and push the buckle 4 downward so that the buckle 4 passes through the sealing film inlet of the beverage cup and enters the inside of the beverage cup. The limiting plate 7 presses on the top of the beverage cup to limit the buckle 4. After the limiting is completed, the ventilation strip 5 opens the sealing film inlet to prevent the surface of the PHA straw 1 from sticking to the surface of the sealing film inlet. This prevents the user from having difficulty sucking due to the difference in pressure inside and outside. Finally, after use, the PHA straw 1 can be degraded under various conditions such as soil, fresh water, seawater, household compost, industrial compost, and anaerobic digestion.

[0025] In summary, this PHA bendable straw works by inserting the bottom of the PHA straw 1 into the inside of the beverage cup. After insertion, the air vent 5 is pressed inward, and the buckle 4 is pushed downward, allowing the buckle 4 to pass through the sealing film inlet of the beverage cup and enter the inside of the cup. The limiting plate 7 presses against the top of the beverage cup to limit the buckle 4. After limiting, the air vent 5 opens the sealing film inlet, preventing the surface of the PHA straw 1 from sticking to the surface of the sealing film inlet, which would make it difficult for the user to drink due to the difference in pressure inside and outside. Finally, after use, the PHA straw 1 can be degraded under various conditions such as soil, fresh water, seawater, home composting, industrial composting, and anaerobic digestion. Therefore, it has the advantages of easy degradation, high temperature resistance, and not easy to fall off. It solves the problems of existing biodegradable straws, such as harsh degradation conditions, low degradation efficiency, inability to withstand high temperatures and softening when exposed to high temperatures, and the straw surface being too smooth and falling off when placed in the beverage cup again.
