Method for making container cup and structure thereof

Abstract

The invention relates to a manufacturing method of a container cup and a structure thereof, which belongs to the daily article class. The invention comprises a paper cup and a cup-shaped electronic bridging foaming body, wherein the inner surface or the outer surface of the paper cup is sprinkled and covered with a film layer, and is pressed into the paper cup through shape cutting; the cup-shaped electronic bridging foaming body is formed by being bonded in a hot pressing way after an electronic bridging foaming plate is manufactured into a sector body through printing, shape cutting and stripe pinching, the inner peripheral of the cup-shaped electronic bridging foaming body is ensured to produce softening viscosity in the hot pressing way, then the paper cup is directly covered on and bonded with the inside of the cup-shaped electronic bridging foaming body, and meanwhile a convex ring with a oversize diameter is formed at the outer part of the paper cup lip where the cup-shaped electronic bridging foaming body is positioned. The structure has the advantages that the protective effect is good, the thermal insulation function is good, the water absorbability is low, the appearance is smooth and artistic, the structure is not easy to be metamorphic, the drug fastness is good, the processing is easy, etc.

Description

technical field [0001] The invention relates to daily necessities, in particular to a method for making a container cup and its structure. Background technique [0002] As we all know, a commonly used paper container includes a container body, a bottom plate, and a coaming plate extending upward from the periphery of the bottom plate. The bottom plate and the coaming plate together define an accommodating space with an upper open end; an inner waterproof layer, Draped on the top surface of the bottom plate and the inner peripheral surface of the coaming; and a foam layer, which can be insulated and coated on the outer peripheral surface of the coaming of the container body; The outer waterproof layer between the inner peripheral surfaces of the foam layer; the foam layer and the outer waterproof layer are made of the same material and formed by hot-melt; the inner waterproof layer is made of polyethylene and polypropylene group; the material of the foam layer is selected fr...

Problems solved by technology

[0005] The object of the present invention is to provide a method for making a container cup and its structure, which solves the problem that the container body and the foam layer of a commonly used container cup are connected in a nesting manner, and the combination is not reliable, and the two components are prone to detachment and falling; other The waterproof layer is used as the bonding medium between the aforementioned two components. When coating the outer waterproof layer on the outside of the formed container body or inside the foam layer, there will be problems such as difficulty in coating the entire circumference, uneven coating and inaccurate bonding.
