Double-layer paper soup bowl paper cover with respiration function

Abstract

The invention provides a double-layer paper soup bowl paper cover with a respiration function. The double-layer paper soup bowl paper cover comprises a double-layer bottom cover and a paper ring connected with the double-layer bottom cover, the double-layer bottom cover comprises an upper bottom cover sheet and a lower bottom cover sheet, the upper edge of the paper ring and the outer edge of the double-layer bottom cover are in involute contact, the upper bottom cover sheet and the lower bottom sheet are provided with multiple holes, the holes formed in the upper bottom cover sheet and the holes formed in the lower cover sheet are staggered, the upper surface of the lower bottom cover sheet is provided with multiple salient points, the salient points and the holes formed in the upper bottom cover sheet are staggered, and the inner wall of the paper ring is provided with annular protrusions in the circumferential direction of the paper ring. According to the double-layer paper soup bowl paper cover with the respiration function, hot air inside a paper soup bowl vessel is discharged from the holes formed in the lower bottom cover sheet, shielded by the upper bottom cover sheet and then discharged from the holes formed in another location, in this way, hot air in the vessel can be discharged, and the effect that pollutants such as dust can be prevented from making contact with food inside the vessel is achieved.

Description

technical field [0001] The invention relates to the technical field of paper soup bowls, in particular to a double-layer paper soup bowl cover with breathing function. Background technique [0002] At present, there are paper soup bowl paper lids on the existing market, or a paper circle plus a bottom cover method, or a paper circle plus a bottom cover method with two holes. These two methods have the following disadvantages: [0003] 1) When the non-porous paper is covered on the container with hot soup, the heat in the container cannot be removed, and a relatively airtight container will generate a higher atmospheric pressure than the outside of the container. fall off in the paper cover; [0004] 2) When a layer of paper cover with two holes is placed on the container with hot soup, although the hot air in the container can be discharged, the two holes on the bottom cover are in direct contact with the air, and dust and other pollutants in the air may contaminate the T...

AI Technical Summary

Problems solved by technology

[0003] 1) When the non-porous paper is covered on the container with hot soup, the heat in the container cannot be removed, and a relatively airtight container will generate a higher atmospheric pressure than the outside of the container. When the paper cover is held by hand, the container is easy to leak fall off in the paper cover;

[0004] 2) When a layer of paper cover with two holes is placed on the container with hot soup, although the hot air in the container can be discharged, the two holes on the bottom cover are directly in contact with the air, and dust and other pollutants in the air may contaminate the The food in the container poses a health hazard
