Description

Flexible paper straw

Technical Field

The application relates to a structure of a straw, in particular to a bendable paper straw.

Background

Diet utensils vary from country to country or from country to country due to differences in diet culture, but a drinking straw, which is one of the diet utensils, is a common utensil for drinking beverages that is not used in any country or diet culture.

The number of straws consumed by the global population daily is quite staggering in modern society due to the extremely widespread use of the improved living standard of the materials, whether packaged beverages or prepared beverages on site. At present, most of used straws are mainly plastic straws, although the volume of each plastic straw is not large, the quantity of the plastic straws accumulated and used every day is not comparable with that of other plastic tableware, and because the volume of the plastic straws is not large, the plastic straws are not easy to treat even after being recycled, huge quantities of straw wastes are generated every day, and the huge quantities of plastic wastes not only can cause harm to the environment, but also can increase a large amount of treatment cost.

In order to solve the problems of the traditional plastic straws, a reusable straw is available in the market at present, and a typical straw is made of stainless steel, although the stainless steel straw has the advantage of being reusable, the straw needs to be carried about, the user is still limited, the popularization rate is low, and the straw cannot completely replace the traditional plastic straw in a short time and solve the environmental protection problem caused by the plastic straw.

In addition, although the known paper straw can be naturally decomposed or incinerated, which is beneficial to solving the environmental problem, the known paper straw cannot be bent or bent by 180 degrees, and obviously cannot meet the use habits of certain products or consumers needing to bend and use the straw.

In the granted patent publication No. CN204363621U of Chinese utility model, a paper straw is proposed, in which a plurality of circular grooves are indented on the end of the straw, and the distance between the circular grooves is 5mm-12mm, so that one end of the straw can be properly bent. Although the outer surface of the paper straw has a plurality of circular tracks, the circular tracks are only a structure recessed on the outer surface of the paper straw, the inner side wall of the paper straw is still a flat surface, and the plurality of circular tracks are widely and dispersedly spaced, so that resistance to bending the paper straw is provided, and the paper straw is not easy to maintain a proper bending state after bending. Therefore, it remains one of the technical goals of the related art to improve the curved configuration of paper drinking straws and to maintain a stable shape.
