Description

Paper straw

This creation is about a paper straw.

According to the modern people's livelihood products technology, and the modern life is busy, the demand for food is greatly increased, especially in the case of drinks, it is a daily life for modern people, in order to avoid spills and lips, the public A straw is commonly used to smoothly absorb the liquid in the drink. However, since the straw is made of plastic materials, the number of straws used every day in the world is very alarming. The plastic waste thus produced has caused very serious environmental pollution in the world. Later, paper straws appeared on the market. The paper material has the characteristics of being recyclable and easy to be decomposed to solve environmental problems. However, the conventional paper straw has poor waterproof effect. When the paper straw contacts the liquid, it will begin to soften and rupture, which may result in the user not being able to smoothly drink the beverage. Suction, there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive paper straw to solve the above problems.

The main purpose of the present invention is to provide a paper straw which not only reduces environmental pollution, but also has a simple structure and a good waterproof effect, so as to avoid softening or cracking of the paper straw when used, which can improve durability and Repeat usage.

To achieve the above object, the present invention provides a paper straw comprising a tube body. The tube body comprises a substrate formed by a rectangular sheet of paper sheet and two first laminating layers, and the two first laminating layers are respectively disposed on opposite sides of the sheet of paper. The paper sheet has two opposite long sides and two opposite short sides, the substrate is rolled along the two short sides and a part of the substrate overlaps, and the two first laminating layers overlap each other. The fuse is bonded to form the tube.

The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to FIG. 1 to FIG. 3, a preferred embodiment of the present invention is shown. The paper straw of the present invention comprises a tube body 1. The tube body 1 comprises a substrate 2, and the substrate 2 is formed by a rectangular sheet. The paper sheet 21 and the two first coating layers 22 are respectively disposed on the opposite side surfaces 211 of the paper sheet 21, and the paper sheet 21 has two opposite long sides. 212 and two opposite short sides 213, the substrate 2 is rolled into a tubular shape along the two short sides 213 and a part of the substrate 2 overlaps, and the overlapping portions of the two first coating layers 22 are thermally fused, The tube body 1 is formed, and the two first coating layers 22 are thermally fused, so that the substrate 2 can be maintained in a tubular shape without being easily spread, and can be more waterproof, so that it can be used after repeated use. Discarded, the paper sheet 21 has an easily decomposable property and can effectively reduce environmental pollution.

Further, each of the first coating layer 22 is a PE (polyethylene) coating or a PP (polypropylene) coating, which is a food grade PE (polyethylene) coating in this embodiment. High security of use.

It is to be noted that in the embodiment, the two long sides 212 and the two short sides 213 are additionally provided with a second laminating layer 23, which is a PE (polyethylene) coating or The PP (polypropylene) coating is also a food grade PE (polyethylene) coating in the embodiment, and the second coating layer 23 is disposed on the two long sides 212 and the two short sides 213. The liquid can be effectively blocked, and the liquid is prevented from penetrating into the paper sheet 21 from the two long sides 212 and the two short sides 213, so that the paper sheet 21 is wetted and softened.

In addition, the width of the substrate 2 overlapping is less than one sixth of the length of the short side 213, so as to prevent the width of the substrate 2 from overlapping too much, and the tube 1 is too thick, and the tube 1 is Since the two first coating layers 22 are thermally fused, and the overlapping portions of the substrate 2 are prevented from being separated, the width of the substrate 2 overlapping can be effectively maintained in the tubular shape without being too wide.

Referring to FIG. 4 to FIG. 6 , in another embodiment, a surface of the substrate 2A is recessed along one side of the short side, and a first step portion 24 is formed. The long side of the substrate 2A is recessed from a side of the first step portion 24 and is provided with a second step portion 25. When the substrate 2A is rolled into a tubular shape along the short side, the first step portion The overlap with the second step portion 25 can effectively reduce the thickness of the overlapping portion of the substrate 2A. In this embodiment, the sum of the depths of the first step portion 24 and the second step portion 25 is equal to the substrate 2A. The thickness is such that the outer surface of the tube body 1A is circular, which is more beautiful and convenient to hold.

In summary, the paper straw of the present invention can be maintained in a tubular shape without being easily spread by the heat-melting bonding of the first coating layer, and can be more waterproof, so that it can be discarded after repeated use. In addition, the paper sheet has an easily decomposable property and can effectively reduce environmental pollution.

Moreover, the second coating layer is disposed on the two long sides and the two short sides, which can effectively block the liquid, and prevent the liquid from penetrating into the paper sheet from the two long sides and the two short sides, thereby causing the paper sheet The material is wetted and softened.
