Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1-8 As shown, the present invention provides a variable-diameter straw, which consists of two deformable pieces 1 joined together to form a pipe body 10, and the middle part of the deformable piece 1 is an easily deformable region 2 that is squeezed to control the change of the pipe diameter. When designing a variable-diameter straw, it is an important consideration to prevent the shrinkage of the straw body during use after the straw is deformed. The reason for the retraction and deformation of the straw is that when the liquid is sucked, the suction force inside the straw is uneven.

[0023] The general design is to put the suction pipe on the ring to prevent the suction pipe from retracting and deforming. But in the actual use process, the suction force that the straw bears is not large. In this case, the variable ...

Abstract

The invention discloses a straw tube with variable tube diameters. Two sides of two deformation sheets are mutually jointed to form a tube body, and the middle part of each deformation sheet is an easy-to-deform area for controlling the size of the tube diameter by extrusion. The deformation sheets are made of a plurality of hard materials, and the adjacent hard materials are connected through soft materials. The deformation sheets are made of an elastic material. The deformation sheets are made of a paper material, each deformation sheet is provided with at least one pre-pressing line, and the pre-pressing line is located in the easy-to-deform area. According to the straw capable of being transformed into a tubular shape from a straight sheet shape, the size of the straw during transportation at ordinary times can be greatly reduced, the space utilization rate of transportation, storage and the like is increased, and the straw is high in structural strength and convenient to machine.

Description

technical field [0001] The invention relates to the technical field of straws, in particular to a straw with variable diameter. Background technique [0002] Specially designed to manufacture straws for different green materials, such as bamboo, wood, paper, etc., to improve the use of green materials in people's lives, and to speed up the construction of a green cycle of an ecological society. [0003] At the same time, it solves the problems of low transportation efficiency of the existing traditional straws, poor structural design strength of the environmental protection straws, and complicated material processing process of the environmental protection straws. Contents of the invention [0004] The object of the present invention is to provide a straw with variable diameter, which overcomes the above-mentioned defects and is easy to process, high in strength and easy to transport. [0005] In order to achieve the above object, the solution of the present invention is:...
