Embodiment Construction

[0031] as attached figure 1 Shown in accompanying drawing 3, the method for making of environmental protection cup of the present invention mainly comprises:

[0032] At least one or both surfaces of a paper / board are covered with a fully biodegradable film layer 11, and then cut and pressed into various paper cups 10, so that they can be directly decomposed into carbon dioxide and water by composting , to achieve the benefits of no burden on the environment and no pollution;

[0033] A foaming cup body 20, made entirely of biodegradable plastics, using supercritical carbon dioxide micro-extrusion foaming technology to make a rolled or flat plate body 200, and then printing, cutting, and folding the pattern or characters of the plate body 200 The second half of the pattern is processed into a fan-shaped semi-finished product, and then the board body 200 is glued into a cup-shaped foam body by means of ultrasonic heat pressing, electric heat pressing, hot air pressing or high-...

Abstract

The invention relates to the manufacture method of environmental cup and a structure thereof, which belongs to articles for daily use. The manufacture method comprises the following steps: applying a biodegradable film layer on at least one or two surfaces of a paper sheet/board, cutting, and pressing to obtain cup, manufacturing foamed board body by foaming a biodegradable plastic or a non-biodegradable plastic in the presence of supercritical carbon dioxide, cutting the board body to desired shape, hot-pressing to obtain a hollow ring cup body, heating the inner section of the ring cup body to melt the surface of the inner section to obtain an adhesive surface, directly sheathing the paper cup inside the ring cup body, and slightly applying a pressure on the outer section of the ring cup body by a mold to form a convex ring with larger diameter at the lips of the cup. The manufacture method has the advantages that the method can prevent the tight shrinking between adjacent cup bodies to take the cup easily, and the product has firm connection, no environment burden and no pollution and high practicability.

Description

technical field [0001] The invention relates to daily necessities, in particular to a method for making an environmentally friendly cup and its structure. Background technique [0002] As we all know, the commonly used cup structure mainly includes a foam cup body as the inner layer, which can directly provide hot and cold food without deformation. The supercritical carbon dioxide micro-extrusion foam cup body is made by advanced technology, and then formed by molding operations; the outer layer is a paper cup body, which is used to cover the outside of the foam cup body, and the outer surface of the paper cup body is printed with characters or patterns; [0003] In the above structure, a paper cup is set outside the foam cup. Since the paper cup and the foam cup are only connected by close fit, there are still concerns about the connection being inaccurate, and the heat resistance of the foam itself is not enough. , It will soften slightly when heated and needs to be impro...
