Description

Paper straw structure

Technical Field

The invention relates to a straw, in particular to a paper straw structure, which can achieve the effects of environmental protection and continuous development of the earth and is an innovative structural design with commercial application.

Background

With the progress of manufacturing technology, the daily edible appliances used by people are also increasingly environment-friendly; the straw is typically a cylindrical tube made of plastic, which can be used to suck the contents of the container, for example: viscous or liquid substances or beverages. When the food is eaten, the container or the cup body is not arranged at the mouth of a user, namely the mouth of the user does not contact any part of the container or the cup body, only the suction pipe is inserted into the container or the cup body, and then the substance or the beverage in the container or the cup body can be sucked into the mouth of the user by applying the suction force of the user (namely, the negative pressure is formed inside the mouth, and the atmospheric pressure is formed by the external air), so that the lips of the user can be prevented from directly contacting the edge of the container or the cup body, and the food is convenient, safe and sanitary.

However, the conventional plastic straw structure can only be disposed of or incinerated for combustion after use. The plastic straw is a material that cannot be decomposed by natural environment, and when the straw is directly discarded on the road surface or in the ocean, not only can the environmental beauty be caused, but also the fishes in the ocean can be caused to eat plastic products by mistake, and finally people eating the fishes eat excessive harmful substances or plastic fragments. When the plastic straw is incinerated, the generated dioxin is harmful toxic gas, which causes serious air pollution and affects human health, so the plastic straw structure has many improvement spaces.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the conventional plastic straw cannot be naturally decomposed and reused, and toxic gases such as dioxin and the like are generated by burning the plastic straw, so the conventional plastic straw does not meet the environmental protection requirement and the continuous development trend of the earth.

In order to solve the above problems, the present invention discloses a paper straw structure, which is characterized by comprising:

the long paper piece is provided with two short sides and two long sides, the two long sides are respectively provided with a first joint long edge and a second joint long edge, and the surface of the paper piece is covered with a first waterproof membrane capable of isolating liquid;

cutting one short edge of the paper sheet to form a cutting part, wherein the cutting part comprises a first cutting edge, a second cutting edge, a third cutting edge and a fourth cutting edge, the first cutting edge is connected with one long edge of the paper sheet and is adjacent to the short edge of the paper sheet, the second cutting edge is oppositely inclined towards the connection point of the first cutting edge, the third cutting edge is connected with the second cutting edge and is oppositely inclined towards the connection point of the second cutting edge, the fourth cutting edge is connected with the other long edge of the paper sheet, and the cutting part is in an M-shaped outline; the second cutting edge and one of the short edges of the paper sheet and the third cutting edge respectively have the same first included angle with one of the short edges of the paper sheet; the extension lines of the first cutting edge and the second cutting edge and the extension lines of the fourth cutting edge and the third cutting edge respectively have the same second included angle; when the paper sheet is curled, the first cutting edge is overlapped on the third cutting edge, and the fourth cutting edge is overlapped on the second cutting edge, so that the short edge of the paper suction pipe forms a sharp-pointed protruding thorn part;

wherein the second included angle is 2 times of the first included angle;

by the structure, the paper sheet is curled to enable the first joint long edge and the second joint long edge to be overlapped and lapped with each other to form a slender cylindrical paper suction pipe, and the first waterproof film is attached to the inner surface of the paper suction pipe.

Wherein, the 1/3 position different from the spur part and being the long side is provided with a telescopic tube part which can be bent, extended and compressed, and the telescopic tube part is formed by a plurality of concave ring bodies and a plurality of convex ring bodies which are arranged alternately.

Wherein, the side of the paper sheet different from the first waterproof membrane is covered with a second waterproof membrane which can isolate liquid, and the second waterproof membrane is adhered on the outer surface of the paper suction pipe.

Wherein, a printing layer is covered between the second waterproof film and the paper sheet, and the printing layer comprises one or the combination of figures, colors and marks.

Wherein the first included angle is 15-75 degrees, and the second included angle is 30-150 degrees.

The first joint long edge and the second joint long edge are the same in width, and the width of the first joint long edge and the second joint long edge is 1/6-1/3 of the short edge of the paper sheet.

Wherein the paper sheet is edible wood pulp paper or decomposition paper.

Wherein the thickness of the paper sheet is 0.05-0.15 mm.

By means of the innovative unique design, the paper straw structure has the following advantages:

1. the paper straw can be decomposed in natural environment and can be recycled.

2. The paper-made suction pipe is burnt, and toxic gas such as dioxin and the like which cause harm to human bodies can not be generated.

3. The protruding part can be inserted into the sealing film layer of the container or the cup body to suck the beverage or liquid in the container or the cup body.

4. The telescopic tube part can be bent to adapt to the direction angle and the position of the mouth of a user, so that the beverage in the container or the cup body can be comfortably sucked.

5. The printing layer can be printed with color as the identification mark of the straw.

6. The invention can achieve the effects of environmental protection and continuous development of the earth.
