[0034] Next, see Figure 1 ~ Figure 2B As shown in the first embodiment of the present invention, one of the short sides 101 of the paper sheet 10 is cut to form a cutting portion 21, and the cutting portion 21 includes a first side adjacent to the short side 101 by one of the long sides 102. Cutting edge 211, a second cutting edge 212 connected to the first cutting edge 211 and inclined inversely towards its connection point, a third cutting edge 213 connected to the second cutting edge 212 and inclined inversely toward its connecting point 1. A fourth cutting edge 214 connected to the third cutting edge 213 and inclined towards the opposite direction of the connection point, the fourth cutting edge 214 is connected to the other long side 102, so that the cutting portion 21 has an M-shaped profile The second trimming 212 and the one of the short sides 101 of the paper 10, the third trimming 213 and the one of the short sides 101 of the paper 10 respectively have the same firs...

Abstract

Disclosed is a paper straw structure. The paper straw structure comprises an elongated paper sheet, wherein the paper sheet has short edges and long edges; cutting parts are formed on the short edges;the long edges are provided with a first joint long edge and a second joint long edge separately; and the surface of the paper sheet is covered with a first waterproof film capable of isolating liquid. By means of the structure, the first joint long edge and the second joint long edge are overlapped and are in lap jointing with each other by curling the paper sheet to form an elongated cylindrical paper straw with a sharp spike part; and therefore, the paper straw structure provided by the invention can achieve the effects of environmental protection and earth permanent development, and is anovel structural design capable of achieving commercial application.

Description

technical field [0001] The invention relates to a straw, especially a paper straw structure, which can achieve the effect of environmental protection and sustainable development of the earth, and is an innovative structural design with commercial application. Background technique [0002] With the advancement of manufacturing technology, the edible utensils used by people are becoming more and more environmentally friendly; straws are generally cylindrical tubes made of plastic, which can be used to suck substances in containers, such as viscous or liquid substances or drinks. When eating, the container or cup does not need to be placed in the user's mouth, that is, the user's mouth does not need to touch any part of the container or cup, and only needs to insert the straw into the container or cup, and then use the user (that is, the inside of the mouth is a negative pressure, and the outside air is an atmospheric pressure), the substance or drink in the container or cup c...
