Description

Technical Field

[0001] The invention relates to the technical field of packaging, in particular to a disposable paper container for food packaging. Background Art

[0002] With the development and progress of the times, people's consumption level and requirements are constantly improving, which has promoted the diversification of food packaging containers. At present, large-taper paper bowls are rarely used due to their high manufacturing cost and difficulty; paper plate containers and paper box containers are mostly formed from a piece of cardboard, the product stiffness is very poor and the material utilization rate is low. In summary, the paper utilization rate of paper bowls, paper plates, and paper boxes on the market is not high, and there is a lot of waste. Since they are all disposable items, they have many shortcomings. The product in this case can improve the material utilization rate of paper containers such as paper bowls, paper plates, and paper boxes, and greatly reduce the difficulty of manufacturing large-taper paper bowls. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a disposable paper container for food packaging, which solves the problems of difficulty in manufacturing large-taper paper bowls and waste of materials.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A disposable food packaging paper container, comprising:

[0005] The container body is formed by bonding two or more paperboards into a conical curved surface or a square pyramid curved surface, and the upper opening is rolled into a circular edge or pressed into an arc edge or a flat edge;

[0006] The bottom paper is a round or square paperboard matched with the container body, the bottom paper is bonded to the container body, and the bottom paper is located at the bottom of the container body.

[0007] Preferably, the container body and the base paper material are both paperboard.

[0008] Preferably, the container body is formed by bonding two or more paperboards at overlapping portions to form a conical surface or a square pyramidal surface.

[0009] Preferably, the generatrix of the conical surface or the square pyramidal surface of the container body is a straight line or a curve.

[0010] Preferably, the inner surface of the container body and the upper surface of the base paper are coated with PE coating, PP coating or water-based environmentally friendly glue.

[0011] Preferably, the outer surface of the container body is provided with printed patterns and texts, and the overlapping parts of the container body are blank areas.

[0012] Preferably, the bottom of the container body is a vertical foot or a flat bottom after being bonded to the base paper.

[0013] The present invention provides a disposable paper container for food packaging, which has the following beneficial effects:

[0014] 1. The container body of the present invention is heat-formed by a mold, and whether it is a conical curved surface or a square pyramid curved surface, it can maintain its designed shape; the container body is formed by bonding two or more cardboards, and the bottom is bonded to the base paper. This bonding method enhances the overall structural strength of the container; the bottom of the container body is bonded to the base paper to form a vertical foot or flat bottom design, so that the container can adapt to different placement environments; the inner surface of the container body and the upper surface of the base paper are coated with PE coating, PP coating or water-based environmentally friendly glue. PE coating, PP coating and water-based environmentally friendly glue can not only play the role of bonding the overlap of the container body and the connection with the base paper, but also play the role of waterproofing and leak-proofing.

[0015] 2. The container disclosed in the present invention can significantly improve the material utilization rate of existing paper container production, and the container has a certain degree of stiffness and reduces the difficulty of manufacturing large-taper paper bowls.
