Mold for anti-scalding paper-plastic container

The invention relates to a mold for anti-scald paper and plastic containers, in particular to a mold for anti-scald paper and plastic containers capable of completing the manufacture of anti-scald paper and plastic containers.

Press, "Takeaway paper cups" and "Takeaway paper bowls" are "disposable food containers" often seen in modern life. The current "disposable food containers" are commonly made by paper manufacturers, so there are also "disposable paper containers" "And" disposable paper containers" --- and other names.

The common paper container is made of paper sheets. By bending, laminating, rolling, etc., a body surrounded by a circle and a bottom sheet bonded to the bottom are defined by the body and the bottom sheet. The volume range is a holding space. The bottom of the body and the periphery of the paper of the body are combined by means of lamination and rolling to cover a bottom space, and the top of the body of the body is outward The means of bending produces a top edge, and therefore there must be a gap inside the top edge.

Conventional paper containers are only made of thin paper sheets, so they are barely used to hold hot food (hot soup or hot coffee, hot tea --- etc.) without other better alternatives. However, in practice, he knows that paper containers have poor anti-scalding effect, poor heat resistance, easy softening when heated (especially the top edge is easier to soften) and the lack of heat dissipation at the bottom.
