Description

Flexible paper straw

The present invention relates to a straw structure, especially a flexible paper straw.

Due to the differences in food culture, the food utensils of different countries or ethnic groups will also be different, but one of the eating utensils, straws, is a common utensil used for smoking drinks regardless of the country and food culture.

Due to the improvement of material living standards in modern society, whether it is packaged beverages or on-site beverages are extremely popular, so the number of straws consumed by the global population daily is very alarming. At present, most of the straws used are still mainly made of plastic straws. Although the size of each plastic straw is not large, the cumulative number of daily use is not comparable to other plastic tableware. The volume is not large, and it is not easy to dispose even after recycling. Therefore, a huge amount of straw waste is generated every day in the world. This large amount of plastic waste will not only cause harm to the environment, but also increase a lot of processing costs.

In order to solve the problem of traditional plastic straws, there is a reusable straw in the market. The typical one is a straw made of stainless steel. Although this stainless steel straw has the advantage of being reusable, it needs to be carried with you. The number of people is still limited and the penetration rate is very low. In a short time, they still cannot completely replace the traditional plastic straws and solve the environmental problems caused by plastic straws.

In addition, although the known paper straws can be naturally decomposed or incinerated, it is conducive to solving environmental problems However, the known paper straws cannot be bent or bent at 180 degrees, which obviously cannot meet certain products or consumer habits that require the use of straws.

In the authorized Chinese utility model patent authorization announcement number CN204363621U, a paper straw is proposed, in which a plurality of ring patterns are depressed at the end of the straw, and the distance between each ring pattern is between 5mm-12mm, so that the end of the straw can be properly bent. Although this patented technology has a plurality of ring patterns on the outer surface of the paper straw, these ring patterns are just a structure that is recessed on the outer surface of the paper straw. The inner side wall of the paper straw is still a straight surface, and the plurality of channels The spacing of the ring patterns is large and scattered, and the bending paper tube will have resistance feedback, and it is not easy to maintain a proper bending state after bending. Therefore, improving the curved structure of the paper straw and maintaining it in a stable shape is still one of the technical goals of the related industry.

The technical problem to be solved by the present invention is to provide a bendable paper straw with better bending effect and ease of use.

Based on solving the above technical problems, the novel flexible paper straw includes: a paper tube body with a spiral tube structure having at least two layers of tube walls made of viscose and paper material, the viscose being interposed between any two layers Between adjacent and overlapping tube walls, the paper tube body has a bendable section. The bendable section is a bellows structure. The bellows structure is a continuous zigzag shape on the cross section of the pipe wall. After the viscose is dried, the normal state of the bellows structure is maintained close to the side-by-side state to provide room for extension deformation during bending.

As a preferred technical solution of the novel flexible paper straw, the paper pipe body is prepared by using two layers of paper sheet materials and viscose into a spiral pipe structure with two layers of pipe walls.

As a preferred technical solution of the novel flexible paper straw, the paper tube body is A three-layer paper sheet material and adhesive are used to prepare a spiral tube structure with three-layer tube walls.

As a preferred technical solution of the novel flexible paper straw, the corrugated tube structure presents a continuous triangular zigzag shape on the cross section of the pipe wall, and any two adjacent triangular zigzag shapes are the same size.

As a preferred technical solution of the novel flexible paper straw, the corrugated pipe structure presents a continuous triangular sawtooth shape on the cross section of the pipe wall, and any two adjacent triangular sawtooth shapes are different in size, so that the bellows structure In any two adjacent triangles, the diameter of the zigzag is different.

As a preferred technical solution of the novel flexible paper straw, the bellows structure presents a continuous arc wave shape on the cross section of the pipe wall.

As a preferred technical solution of the novel flexible paper straw, the inner wall surface of the paper pipe body is coated with a layer of waterproof shower film, and the material of the waterproof shower film is biodegradable.

The waterproof film is polylactic acid (PLA) film.

The beneficial effect of the novel flexible paper straw is that it can solve the environmental problems caused by traditional plastic straws and the technical problems that the paper straws cannot be bent or are not easy to bend and it is difficult to maintain the curved structure stably.
