Environmentally friendly container with bioplastic shell and glass lining

Abstract

An environmentally friendly container with bioplastic shell and glass lining includes a shell defining a hollow body of the container; a wall of the shell that includes a bioplastic resin; and a lining that includes a liquid glass and coats a surface of the wall. Embodiments may include an opening at an end of the shell; a cap that includes the bioplastic resin of the shell; and a cap lining on an inner surface of the cap, the cap lining forming a closure with the lining of the wall so that the container provides a sealed cavity; wherein the lining is on an inner surface of the wall of the shell, thereby fully lining an interior cavity of the container with glass; and the bioplastic resin includes PLA, PLLA, PDLA, PHA, PCL, or PBT.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to containers and specifically to an environmentally friendly container with a bioplastic shell and a glass lining.[0002]There is a desire to make products that are environmentally friendly, from plant materials that are compostable, which thus can lead to zero waste, thereby reducing waste. This can be achieved by using material that are compostable and are from a plant source, namely Bioplastic resins. We need to move away from recycling and take a zero waste approach.[0003]Traditionally, many drinks and beverages such as soft drinks, water, juices, wine, beer, and milk have been supplied in glass, aluminum or plastic bottles. However, these glass, plastic and aluminum materials require much more energy than bioplastic materials to be made into bottles. Bioplastics and ultra-thin liquid or flexible glass are of much lighter weight compared to glass and aluminum thereby decreasing the amount of energy required to produc...

AI Technical Summary

Benefits of technology

The present invention provides a container with a bioplastic resin wall and a lining of liquid glass, which coats the surface of the wall and the inner surface of the cap, creating a sealed cavity sealed in glass. The use of bioplastic resin, such as PLA, PLLA, PDLA, PHA, PCL, or PBT, adds to the eco-friendliness of the container. The method for making the container includes forming a shell that defines a hollow body of the container, and coating the wall with a lining that includes liquid glass. The technical effects of the invention include creating a container that is eco-friendly, stable, and secure, with a sealed cavity that can safely contain various substances without losing their freshness or flavor.

Problems solved by technology

However, these glass, plastic and aluminum materials require much more energy than bioplastic materials to be made into bottles.

Existing containers may be made with a shell made from wood or paper pulp, which offers very poor water vapor and gas barrier.

Glass is generally not “biodegradable”, but it is “degradable” because it eventually breaks down and decomposes by physical forces acting on its structure.
