Polygonal folded type beverage straw

Abstract

The invention relates to a polygonal folded type beverage straw, which comprises a hollow straw, wherein the hollow straw comprises at least four edges and is made of paper or degradable plastics, and a film layer is arranged on the surface of the inner wall of the papery hollow straw. In manufacturing process, a paper sheet is made firstly; the surface of the paper sheet is compounded or poured with the film, and generally, the inner wall is compounded with the film in actual manufacturing process, but both of the two walls also can be compounded with films; the paper sheet having the film is folded and then spliced into a polygonal hollow straw; and the polygonal hollow straw also can be formed by directly blowing the degradable plastics or the polygonal hollow straw is formed by splicing plastic paper which is made of the degradable plastics. The hollow straw has at least four edges (namely being square or polygonal). After the polygonal hollow straw is flatted and folded, the volume is greatly reduced, thereby saving the package and transportation costs. The polygonal hollow straw can be unfolded when the polygonal hollow straw is used. The paper or degradable plastic straw can be automatically degraded after being used, the environment is free from being polluted, and the economic and social benefits are obvious.

Description

technical field [0001] The invention relates to drinking straws, in particular to a polygonal laminated drinking straw. Background technique [0002] People can't do without drinking boiled water (tea) every day. In modern life, along with the development of the beverage industry, more and more people replace tea with beverages, and it is also very common to replace wine with beverages on the dining table. Most beverages need to be poured into cups or adopt straws when drinking, especially when traveling or having meals in the wild, straws have many advantages. But the beverage drinking straw of prior art is plastic round tube, and plastic round tube one can not be flattened and folded, so this pipe volume is big, although the someone has developed the telescoping straw of big tube sleeve small tube, still, volume is still bigger, and packing transportation cost Second, plastic pipes cannot be degraded, are not environmentally friendly, and cause serious white pollution. ...
