Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly paper cups, in particular to an environmentally friendly paper cup. Background Art

[0002] Paper cups are paper containers made by mechanically processing and gluing base paper made of chemical wood pulp. In order to prevent the existing paper cups from softening due to liquid infiltration, a layer of plastic film is usually attached to the inner wall of the paper cup. With the gradual improvement of people's environmental awareness, the call for limiting and banning plastic has been growing in recent years. The increasingly shocking white pollution problem has gradually attracted people's attention. Many places have issued plastic ban regulations. Therefore, paper cups made of plastic film cannot meet environmental protection requirements. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide an environmentally friendly paper cup. The paper cup is sleeved in the upper cup ring and the lower cup ring by arranging an upper cup ring, a lower cup ring, support ribs, a corrugated structure, a rotating shaft, a rotating handle and a handle ring. The paper cup can be lifted by holding the upper cup ring or the lower cup ring, or by the handle ring, the upper cup ring and the lower cup ring. The upper cup ring, the lower cup ring and the support ribs can provide strength support for the outer wall of the paper cup, improve the strength of the paper cup, avoid liquid outflow caused by reduced strength of the paper cup after it becomes soft due to liquid infiltration, and is convenient to use, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An environmentally friendly paper cup comprises a cup body consisting of a paper cup wall and a cup bottom. The inner side of the cup wall and the inner side of the cup bottom are coated with sealing glue, which is a cold sealing glue or a hot sealing glue. The sealing glue is coated on the entire surface of the cup wall and the cup bottom, or the sealing glue is coated on the joint of the cup wall and the contact position between the cup wall and the cup bottom.

[0006] Furthermore, the inner sides of the cup wall and the cup bottom are coated with a waterproof and oil-proof layer.

[0007] Among them, an upper cup ring is arranged on the upper outer ring side of the cup wall, a lower cup ring is arranged on the lower outer ring side of the upper cup ring, and a supporting rib is arranged between the upper cup ring and the lower cup ring.

[0008] Furthermore, the upper cup ring, the lower cup ring and the supporting ribs are all made of paper, and the upper cup ring, the lower cup ring and the supporting ribs all have a corrugated structure.

[0009] Among them, a clamping seat is arranged on the same side of the outer side of the upper cup ring and the lower cup ring, and a through hole is arranged on the clamping seat. A handle is inserted into the through hole. Anti-dropping clamping plates are arranged at both ends of the handle. The clamping seat, the handle and the anti-dropping clamping plate are all made of paper.

[0010] Wherein, a straw clamp ring is arranged on the inner side wall of the cup.

[0011] Furthermore, the straw clamp ring is arranged on the inner side wall of the cup from top to bottom.

[0012] The utility model avoids the use of plastic film by bonding the glue layers at the overlapping position of the cup wall and the bonding position of the cup wall and the cup bottom through hot sealing glue or cold sealing glue. The entire paper cup is made of paper, which can meet environmental protection requirements.

[0013] The utility model arranges an upper cup ring, a lower cup ring, a supporting rib, a corrugated structure, a clamping seat, a handle and an anti-dropping clamping plate, so that the paper cup is sleeved in the upper cup ring and the lower cup ring. The paper cup can be lifted by holding the upper cup ring or the lower cup ring, or by the handle. The upper cup ring, the lower cup ring and the supporting rib can provide strength support for the outer wall of the paper cup, thereby improving the strength of the paper cup, preventing the liquid from flowing out due to the reduction in strength of the paper cup after it is softened by liquid infiltration, and is convenient to use.

[0014] The utility model provides a straw clamping ring so that when the paper cup is in use, the straw can pass through the straw clamping ring and be clamped and fixed on the inner side of the cup wall, thereby preventing the straw from floating up and down due to the buoyancy of the liquid. When sucking the liquid, there is no need to hold the straw with hands, thereby improving the use effect. BRIEF DESCRIPTION OF THE DRAWINGS
