Paper container e.g. paper cup, has biodegradable and adhesive glued layer that is applied on under-surface or peripheral part of paper sheet, so that paper sheet is transformed into container

摘要

The container (1) has an oblong paper sheet (10) on which a biodegradable layer is applied. A biodegradable and adhesive glued layer (20) is applied on an under-surface or a peripheral part of the paper sheet, so that the paper sheet is transformed into the container. The paper sheet comprises a circular lower base (12) connected to an annular shaped peripheral paper wall (13) to form the container. The glued layer is realized in the form of a reinforcement part, which is extended downward and beyond a distal edge of cutting edges, and forms an adhesion part.
