PAPER STRAW CAPABLE OF NINETY-DEGREE BEND

Abstract

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.

Claims

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] 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.sup.2, a gram weight of the second paper layer 13 is 120 g/m.sup.2, and a grain weight of the third paper layer 14 is 60 g/m.sup.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.

[0017] The working process of the present invention is as follows.

[0018] 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.

[0019] 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.

[0020] 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.
