Description

Bendable paper straw structure

This creation relates to a flexible paper straw structure, especially a technical field of environmental straws.

Press, the currently known paper straws are shown in Figures 6 and 7, and Figure 6 is a conventional straw structure made of paper sheets collected by winding and overlapping. The elongated paper sheet is provided with a short side and a long side. The surface is covered with a waterproof film (not shown in the figure), and the long paper sheet is curled so that the long sides overlap each other, overlap and adhere to each other to form a slender cylindrical paper straw 40, and the formed paper straw is in the process of expanding and contracting the tube portion 41 Embossing to provide the bending function of the paper straw 40. However, during the processing of paper straws in the technical field, due to the difference in paper characteristics and plastic materials, the paper straw 40 needs to be embossed into a plastic straw embossing structure. The difficulty of processing, and the strength and tolerance of the paper straw 40 at the edge of the embossing will be reduced, so that the yield of the product processing is low, and the embossed tube portion 41 with sharp angles connected will affect the smooth flow of fluid Fig. 7 is a conventional straw structure formed by combining spirals of paper strips. The straw 50 is provided with a plurality of ring patterns 51 at one end, and the spacing of each ring pattern is between 5mm-12mm, making the end of the straw 50 It can be bent properly. However, due to the large spacing of the ring patterns 51, the bending degree of the paper straw 50 is reduced, resulting in inconvenience in use. Because the above two paper straws have processing and use problems, there is a need for improvement.

In view of the problem of poor stability and ease of use of conventional paper straws, this creation is the bendable paper straw structure that completed this creation.

The main purpose of this creation is to provide a flexible paper straw structure, which includes a paper straw, the paper straw is provided with a paper base, and the paper base system is made of food paper, and the paper base is spirally formed A spiral tube body part, a bending part is provided below the top end of the spiral tube body part, and the bending part is provided with a plurality of arc convex parts and a plurality of contacting dimple ring lines at intervals, and the inside of the bending part is relatively a number of circles The arc convex portion and the number of connected indentation ring line portions are provided with a downstream arc curved wall portion, the downstream arc curved wall portion is in a regular arc-like connected wave shape, and the circular arc convex portion provided between the two connected indentation ring line portions is The distance is 1.5~2mm, the formation of the bent part is to put the embossing forming mold into the top end of the paper straw, and the embossing roller is rolled against the paper straw with the embossing forming mold to form the number of bent parts The arc-shaped convex part and the number-connected dent ring line part, by the number of the arc-shaped convex part of the bending part and the number-connected dent ring line part cooperate, the paper straw is provided with the two ends of the bending part can be easily bent at a large angle Folding, and the number of arc convex parts and the number of connected indentation ring line parts provided in the bending part have not changed the strength and tolerance of the paper straw due to the processing method, and it is not easy to produce degumming of the spiral tube body relative to the bending part Separation, and the overall processing method of the bending part is simple, and the fluid flows from the spiral tube body through the bending part under suction, and the downstream curved wall part will not affect the smoothness of the fluid flow; There is a beveled end edge to facilitate the puncture of the sealing film of cup beverages; with the above structure, the paper straw has a high degree of bending flexibility, and the processing and production method is simple, so as to achieve the convenience of processing and functionality Good effect.
