The anti-scalding paper cup comprises a cup bottom and a paper cup body fixed on the bottom of the cup, characterized in that it further comprises not less than one heat insulating sticker ear attached on the outer side of the paper cup body, the heat insulating sticker ear is inside And two layers of different heat shrinkage factors are combined to form a material.
A slit is formed in the middle, and vertical adhesive tapes are arranged on the inner layers on the left and right sides of the slit, and are respectively slit to the adhesive tape at the top and bottom ends of the slit. The above technical solution is adopted, that is, the thermal insulation shrinkage coefficient of the inner and outer composite materials is different by the thermal insulation shrinkage attached to the outer side of the paper cup body, and the inner layer shrinks more than the outer layer to form a partition. The slot of the hot lug is bounded, and the left and right sides are each facing the oppositely contracted tile shape with the adhesive tape as the central axis, so that an air layer is formed between the heat insulating sticker ear and the paper cup, thereby ensuring the insulation of the paper cup and the ear. Thermal performance. The consumer wears a paper cup with a hot drink by holding the heat-insulating ear, and is no longer hot, and feels comfortable when used.
