Structural improvement for cup container

Abstract

A structural improvement for a cup container includes the following structures. An internal layer paper cup having an internal paper cup bottom is bonded to a bottom of the cup container. A foam layer is bonded to an exterior of the internal layer paper cup. An external layer paper cup then is bonded to an exterior of the foam layer. A foam bottom and an external paper cup bottom are bonded to an external bottom of the internal paper cup bottom in order. The internal surface of the internal layer paper cup and an upper of the internal paper cup bottom are coated with waterproof layers. The foam material of the foam layer can be a biodegradable material, or non-biodegradable materials. The foregoing waterproof layers can be a biodegradable material, or can be a non-biodegradable material.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a cup container, and more particularly to the structural improvement for the cup container that bonds the foam layer between the internal layer paper cup and the external layer paper cup.BACKGROUND OF THE INVENTION[0002]A conventional cup container has an internal layer paper cup and a foam layer, and can have an improvement structure of interchanging the relative positions of the foregoing internal and external layers.[0003]The foregoing conventional structure has a drawback of complex manufacture procedure although the foregoing conventional structure can achieve functions of warn keeping, cold keeping, etc.[0004]Accordingly, to overcome the foregoing shortcoming, the inventor(s) of the present invention based on years of experience in the related field to conduct extensive researches and experiments, and finally invented a structural improvement for a cup container.SUMMARY OF THE INVENTION[0005]A primary object of the p...

AI Technical Summary

Benefits of technology

[0007]1. Since the three layer cups utilize the overall bonding, the structural strength is enhanced to reduce the thicknesses of the internal layer paper cup and the external layer paper cup. The paper price can be effectively cost down to reduce the manufacture cost when paper price keeps on rising.

[0009]3. When the external layer is wrapped by the external layer paper cup with fine structure density, exquisite printing then is carried on to beautify products and attract purchase intention of consumers, thereby improving efficiency.

Problems solved by technology

The foregoing conventional structure has a drawback of complex manufacture procedure although the foregoing conventional structure can achieve functions of warn keeping, cold keeping, etc.
