A paper straw capable of a ninety-degree bend is compositely formed by spirally rolling a paper strip and trimming two ends of the rolled paper strip. One end of the straw is evenly configured with eight to twelve annular grooves by pressing. The paper strip is formed by combining a first paper layer, a second paper layer, and a third paper layer, so that the straw would not get soft during use. By configuring a plurality of annular grooves with a predetermined interval, the straw is capable of being fully bent by ninety degrees without significantly reducing the inner diameter of the straw at the bent region. The paper straw can be fully degraded after use, so no plastic pollution will be caused, and puts less pressure on the environment. Therefore, the paper straw can effectively replace the plastic straw used in the market.

Technical Field
The present invention relates to the technical field of straws, in particular to the technical field of paper straws capable of ninety-degree bends.

Background
The straws are divided into two types, i.e. vertical and flexible. The vertical straw may have a single tube structure or a telescopic tube structure. The flexible straw is relatively convenient for drinking and has a large market share. At present, most of the food-grade beverage drinking straws in the market are made of plastics. Although the plastic straws are convenient to use, the discarded plastic straws after use are difficult to recycle due to their small sizes. Moreover, since most of the plastic straws are nondegradable, puts a great pressure on the environment. Compared with plastic straws, paper straws not only can be recycled and reduce plastic pollution, but also have more refined and beautiful appearance with the improvement of modern technology. The paper straws are very suitable for occasions such as festival parties, etc. However, it is difficult for paper straws to achieve a ninety-degree bend, which brings inconvenience to consumers.

Summary
The objective of the present invention is to solve the problems in the prior art, and provide a paper straw capable of a ninety-degree bend. The paper straw is made by spirally rolling a paper strip combined by three paper layers having different gram weights, so that the straw would not get soft during use. Subsequently, the paper straw is configured with a plurality of annular grooves with a predetermined interval to make the straw capable of being bent by ninety degrees without significantly reducing the inner diameter of the straw at the bent region. The paper straw can be fully degraded after use, so no plastic pollution will be caused, and puts less pressure on the environment. Therefore, the paper straw can effectively replace the plastic straw used in the market.
In order to achieve the above objective, the present invention provides a paper straw capable of a ninety-degree bend, which is compositely formed by spirally rolling a paper strip and trimming two ends of a rolled paper strip. One end of the paper straw is evenly provided with eight to twelve annular grooves by pressing. The paper strip is formed by combining a first paper layer, a second paper layer, and a third paper layer.
Preferably, a width of the paper strip ranges from 1.3 cm to 1.5 cm.
Preferably, the paper straw has a circular cross section, the third paper layer is located outside the second paper layer, and the second paper layer is located outside the first paper layer. A gram weight of the first paper layer is 120 g/m^2, a gram weight of the second paper layer is 120 g/m^2, and a gram weight of the third paper layer is 60 g/m^2.
Preferably, an outer side of the third paper layer is printed with color and pattern.
Preferably, the annular grooves are arranged starting from a position 2.0 cm-2.2 cm away from an end of the straw and extending towards a middle portion of the straw.
Preferably, an interval of the annular grooves ranges from 0.6 cm to 0.7 cm.
The present invention has the following advantages. The paper straw of the present invention is made by spirally rolling a paper strip combined by three paper layers having different gram weights, so that the straw would not get soft during use. Also, the paper straw is configured with a plurality of annular grooves with a predetermined interval to make the straw capable of being bent by ninety degrees without significantly reducing the inner diameter of the straw at the bent region. The paper straw can be fully degraded after use, so no plastic pollution will be caused, and puts less pressure on the environment. Therefore, the paper straw can effectively replace the plastic straw used in the market.
The characteristics and advantages of the present invention will be described in detail through the embodiments with reference to the drawings.

Brief Description of the Drawings
- FIG. 1 is a front view of a paper straw capable of a ninety-degree bend of the present invention; and
- FIG. 2 is a top view of a paper straw capable of a ninety-degree bend of the present invention.
In the drawings: 11-annular groove, 12-first paper layer, 13-second paper layer, 14-third paper layer.

Detailed Description of the Embodiments
Referring to FIG. 1 and FIG. 2, the present invention provides a paper straw capable of a ninety-degree bend, which is compositely formed by spirally rolling a paper strip and trimming two ends of a rolled paper strip. One end of the paper straw is evenly provided with eight to twelve annular grooves 11 by pressing. The paper strip is formed by combining a first paper layer 12, a second paper layer 13, and a third paper layer 14. A width of the paper strip ranges from 1.3 cm to 1.5 cm. The paper straw has a circular cross section, the third paper layer 14 is located outside the second paper layer 13, and the second paper layer 13 is located outside the first paper layer 12. A gram weight of the first paper layer 12 is 120 g/m^2, a gram weight of the second paper layer 13 is 120 g/m^2, and a gram weight of the third paper layer 14 is 60 g/m^2. An outer side of the third paper layer 13 is printed with color and pattern. The annular grooves 11 are arranged starting from a position 2.0 cm-2.2 cm away from an end of the straw and extending towards a middle portion of the straw. An interval of the annular grooves 11 ranges from 0.6 cm to 0.7 cm.
The working process of the present invention is as follows.
In the working process of the paper straw capable of a ninety-degree bend of the present invention, the end of the straw away from the annular grooves 11 is the end to be inserted into the beverage, and the end of the straw near the annular grooves 11 is the end for sucking. The straw can be gradually bent along the plurality of annular grooves 11 at the position close to the sucking end. Preferably, nine annular grooves 11 are provided, so that the straw would not get broken or flat when the straw is sufficiently bent by ninety degrees. As a result, the change of the inner diameter of the straw at the bent region is reduced.
The paper straw of the present invention is made by spirally rolling a paper strip combined by three paper layers having different gram weights, so that the straw would not get soft during use. Also, the paper straw is configured with a plurality of annular grooves with a predetermined interval to make the straw capable of being bent by ninety degrees without significantly reducing the inner diameter of the straw at the bent region. The paper straw can be fully degraded after use, so no plastic pollution will be caused, and puts less pressure on the environment. Therefore, the paper straw can effectively replace the plastic straw used in the market.
The above-mentioned embodiments are merely intended to illustrate the present invention rather than limit the present invention. Any solution derived by simply modifying the present invention should be considered as falling within the scope of the present invention.
