Abstract
The utility model discloses a paper cup with a sewing thread rolling opening, which comprises a paper cup main body, wherein the paper cup main body is formed by winding a paper cup sheet; sewing threads are arranged at the overlapped positions of the two side edges of the paper cup sheet in the width direction; the lower part of the paper cup main body is connected with a cup bottom. Compared with the prior art, the utility model provides a roll up paper cup of mouth with sewing thread, this paper cup simple structure adopts the coiling of environmental protection sewing thread to make up and forms, and this paper cup has replaced the tradition and has rolled up the method of mouth through glue or ultrasonic bonding polyethylene film, has reduced in the use because plastics are heat-labile, solvent intolerance, decomposes out the poisonous composition harmful to the human body.
Description
Technical Field
The utility model relates to a paper cup with mouth is rolled up to sewing thread belongs to articles for daily use field.
Background
The main base material of the disposable paper cup is paper, while the common paper has high moisture absorption, and paraffin or polyethylene film is required to be sprayed on the inner wall of the paper cup, and then the paper cup is hot-pressed and bonded through glue or an ultrasonic wave curling die. However, in the using process, when the paper cup is contacted with liquid such as high-temperature water, alcohol, oil and the like, partial chemical substances can be separated out, the quality safety problem of the paper cup is caused, and the health of human bodies is seriously harmed.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model provides a roll up paper cup of mouth with sewing thread has changed the tradition and has only leaned on chemical method to bond the paper cup and make the unfavorable situation to human health, environmental protection safety more.
In order to realize the purpose, the utility model discloses a technical scheme is: a paper cup with a sewing thread rolling opening comprises a paper cup main body, wherein the paper cup main body is formed by winding a paper cup sheet; sewing threads are arranged at the overlapped positions of the two side edges of the paper cup sheet in the width direction; the lower part of the paper cup main body is connected with a cup bottom.
Further, the paper cup sheet is fan-shaped; two sides of the paper cup sheet are fixedly connected through sewing threads to form a conical body.
Furthermore, an annular groove is formed in one end, close to the paper cup main body, of the cup bottom; the connecting part of the bottom of the paper cup main body and the cup bottom is embedded in the annular groove, and the paper cup main body and the cup bottom are fixedly connected through sewing threads.
Further, the thickness of the paper cup main body is 0.2mm-0.6 mm.
Furthermore, the sewing thread is an environment-friendly sewing thread and is made of polylactic acid fibers or soybean fibers.
Furthermore, chitosan films are arranged on two sides of the paper cup sheet in the width direction between the encircling and overlapping positions.
Further, the thickness of the chitosan film is 0.1 mm.
The utility model has the advantages that: compared with the prior art, the paper cup with the sewing thread roll opening is simple in structure and formed by winding and sewing the environment-friendly sewing thread, the traditional method of adhering the polyethylene film roll opening through glue or ultrasonic waves is replaced by the paper cup, and toxic components harmful to human bodies due to the fact that plastics are not heat-resistant and solvent-resistant in the using process are reduced.
Drawings
FIG. 1 is a schematic structural diagram of the present embodiment;
FIG. 2 is a partial schematic view of a sewn region of a paper cup according to the present embodiment;
fig. 3 is a schematic view of a paper cup a according to this embodiment.
In the figure: 1. the paper cup comprises a paper cup body, 11 paper cup pieces, 2 sewing threads, 21 chitosan films, 3 cup bottoms.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail through the accompanying drawings and embodiments. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.
Referring to fig. 1, a paper cup with a sewn seam for curling an opening includes a paper cup main body 1, the paper cup main body 1 being formed by winding a paper cup sheet 11; sewing threads 2 are arranged at the overlapped positions of the two side edges of the paper cup sheet 11 in the width direction; the lower part of the paper cup main body 1 is connected with a cup bottom 3.
With continued reference to fig. 1, the paper cup sheet 11 is fan-shaped; two sides of the paper cup sheet 11 are fixedly connected through the sewing thread 2 to form a conical body, which accords with ergonomics and increases the volume of the cup body.
In the embodiment, an annular groove is arranged at one end of the cup bottom 3 close to the paper cup main body 1; the position that the bottom of paper cup main part 1 and bottom of cup 3 are connected is inlayed in the annular groove to through sewing thread 2 with paper cup main part 1 and 3 fixed connection of bottom of cup, through setting up the mode that the annular is connected, the sewing of being convenient for is provided with waterproof construction simultaneously in the annular groove, and waterproof construction specifically is for increasing waterproof film, other pollution-free, the material waterproof film that is insoluble in water such as chitosan film 21.
Referring to fig. 2 and 3, a paper cup is sewn with a partial view in this embodiment by overlapping two overlapped paper cup sheets 11 and closely sewing them together by a sewing thread, while a waterproof chitosan film 21 is provided therein to prevent water from being exposed from the sewing region.
The thickness of the paper cup body 1 is 0.2mm-0.6 mm; the sewing thread 2 is an environment-friendly sewing thread and is made of polylactic acid fibers or soybean fibers; a chitosan film 21 for water prevention is arranged between the overlapping positions of the two side edges of the paper cup sheet 11 in the width direction; the thickness of the chitosan film 23 was 0.1 mm.
The paper cup has simple structure, is formed by winding and sewing the environment-friendly sewing thread 2, replaces the traditional method of bonding the polyethylene film roll opening by glue or ultrasonic waves, and reduces the toxic components harmful to human body due to thermolabile and solvent-intolerant plastics in the using process
