Abstract

The invention discloses a paper cup bowl which comprises a cup barrel. A curled edge is arranged on a cup opening of the cup barrel, and a cup bottom is arranged on the bottom of the cup barrel. The paper cup bowl is characterized in that the curled edge is provided with an edge line with the circular upper portion and the flat lower portion or an edge line with the flat upper portion and the circular lower portion, so that the curled edge is of an oblate structure. According to the paper cup bowl, design is ingenious, and the sealing reliability of connection between the paper cup bowl and apaper cup bowl cover can be better ensured, so that the shelf life of food in the paper cup bowl is effectively prolonged. Meanwhile, the invention further discloses a curled edge molding mould for producing the paper cup bowl with the curled edge structure.

Description

technical field [0001] The invention relates to a paper cup and bowl product and a forming mold for curling the mouth of the paper cup and bowl product. Background technique [0002] The sealed packaging of the food in the paper cup and bowl can be realized by buckling the paper cup and bowl cover on the paper cup and bowl. The paper cup and bowl in the prior art includes a cup and barrel. It usually has a circular edge, that is, the curling is a circular structure. The disadvantage of the above-mentioned circular structure curling is: when the paper cup bowl is buckled on the paper cup bowl lid, the paper cup bowl lid must have a downward pressure action on the cup mouth of the paper cup bowl, due to the compressive strength of the circular edge line of the cup mouth curling Not enough, and the pressing distance is controlled, so there cannot be a large contact pressure between the paper cup lid and the cup opening of the paper cup bowl, so the problem of poor sealing reli...
