Single Piece Paper Container

Abstract

A container for liquids or semi-solid contents is formed from one or more pieces of paper, where the paper openings are sealed and the body of the container is coated with a material that renders the body impermeable to the contents. The coating material could be biodegradable, such that the entire container biodegrades after use. The container could also be sealed using crimping or folding the ends of the paper, and the paper could be layered to improve the impermeability effects.
