Containers comprising cellulose hydrate and methods of manufacture

A cup comprising:

• a bottom (1) and
• a side wall (2) comprising:
• a first layer (5) consisting of cellulose hydrate, and
• a second layer (3) comprising cellulose hydrate, paper, cardboard, pulp, fiber, starch or a mixture thereof,
• wherein the side wall (2) of the cup is impermeable to water,
• wherein the cup consists essentially of plant-based material.

A cup comprising:

• a bottom (1), and
• a side wall (2),
• wherein the sidewall (2) comprises a first layer (5) and a second layer (3),
• wherein the first layer (5) consists of natural rubber or plant-based wax,
• wherein the second layer (3) comprises a mixture of pulp and/or fiber and starch, and
• wherein the cup consists essentially of plant-based materials.

A method of manufacturing a cup comprising a bottom (1) and a side wall (2), comprising:

• providing a first material for a first layer of the side wall (2) of the cup and the bottom (1) of the cup, wherein the first material comprises natural rubber or plant-based wax;
• providing a second material for a second layer (3) of the side wall (2) of the cup and the bottom (1) of the cup wherein the second material comprises a mixture of pulp and/or fiber and starch and additionally water;
• forming the second material to shape a cup comprising the side wall (2) and the bottom (1);
• curing the second material;
• and
• coating the second layer (3) of the side wall (2) of the cup and the bottom (1) of the cup of the second material with the first material, thereby producing the first layer (5) of the side wall (2) of the cup and the bottom (1) of the cup.
