the telescopic easily-folded paper straw as shown in figures 1 to 7 comprises a sucking section 1, a telescopic bending section 2 and an inserting section 3 which are connected in sequence, wherein the length of the sucking section 1 is 1/3-2/3 of the length of the inserting section 3. The telescopic bending section 2 is of a corrugated pipe structure, so that the positions and the distances of the sucking section 1 and the inserting section 3 can be changed at will, and the telescopic bending function is realized.

As shown in fig. 3, the flexible bending section 2 is in a continuous arc wavy shape on the cross section of the pipe wall, and includes a plurality of first protruding pressing rings 6, a plurality of second protruding pressing rings 7 and a plurality of concave pressing rings, the first protruding pressing rings 6 and the second protruding pressing rings 7 are alternately arranged, the concave pressing rings connect the first protruding pressing rings 6 and the second protruding pressing rings 7, and the first protruding pressing rings 6 and the second protruding pressing rings 7 have different sizes. The diameter that is first pressure bulge loop 6 is greater than the diameter of second pressure bulge loop 7 promptly, adopt such structure reason as follows, first pressure bulge loop 6 makes the ductility of straw better, when the straw need be elongated and the wide-angle is crooked, the straw is difficult for taking place deformation and is blockked up, and second pressure bulge loop 7 makes the holistic intensity of straw more secure, according to the difference of function side focus during production, through the second pressure bulge loop 7 of arbitrary quantity of collocation between two first pressure bulge loops 6, make the straw under the prerequisite that satisfies the environmental protection, still have flexible excellent performance of buckling and difficult deformation jam, user's use experience is better. When 2~4 second bulge loops 7 are arranged between two adjacent first bulge loops 6 of flexible bending section 2, the performance of straw is better.

In other embodiments, the corrugated tube structure of the flexible bending section 2 presents continuous triangular saw-toothed shapes on the cross section of the tube wall, and the sizes of any two adjacent triangular saw-toothed shapes are the same or the sizes of any two adjacent triangular saw-toothed shapes are different, so that the diameters of the corrugated tube structure in any two adjacent triangular saw-toothed shapes are different, and the flexible paper straw is more easily bent by 180 degrees at the corrugated tube structure and is not easy to rebound.

As shown in figures 1 and 2, the lower part of the insertion section of the paper suction pipe is provided with a bevel 4, and the angle of the bevel 4 is 30-60 degrees. The structure ensures that the insertion end of the straw is sharper, the straw is convenient to use with smaller strength and can be inserted into packages, meanwhile, the resistance born by the straw is also smaller, and the risk of stress deformation is further reduced. Preferably, the lower part of the insertion section is further provided with a plurality of saw teeth 5, and the plurality of saw teeth 5 are arranged at equal intervals. The serrated structure is also used for increasing the sharpness of the insertion end and facilitating easy package puncture.

As shown in fig. 5 to 7, the paper straw includes a first layer of paper 10, a second layer of paper 11, and a third layer of paper 12, the first layer of paper 10, the second layer of paper 11, and the third layer of paper 12 are strip-shaped paper materials with the same width, the long sides of the first layer of paper 10, the second layer of paper 11, and the third layer of paper 12 are stacked and bonded together in a shingled manner, the three layers of composite paper materials are bonded together in a spiral winding and staggered overlapping manner by a rotating roller 13 to form a paper straw with three layers of pipe walls, the first layer of paper 10 becomes the inner layer of the three layers of composite paper straw, the second layer of paper 11 becomes the middle layer of the three layers of composite paper straw, and the third layer of paper 12 becomes the outermost layer of the three layers of composite paper straw.

The three layers of composite paper materials are bonded with each other in a spiral winding and staggered overlapping mode, so that the whole structure of the straw is more stable and firm and is not easy to loosen, meanwhile, in order to enhance the whole waterproof performance of the straw, an inner waterproof drenching film layer 8 is arranged on the inner surface of the paper straw, and an outer waterproof drenching film layer 9 is arranged on the outer surface of the paper straw, as shown in fig. 4.
