High gloss paper cup

A paper cup of the type having a smooth, high gloss coating and being produced by the method comprising the steps of:

• (a) heating said paper container and said wax coating to a temperature above the congealing temperature of said wax for a time sufficient to cause said wax to form a uniform liquid film on said outside surface;
• (b) imparting a constant angular velocity to said container;
• (c) maintaining the temperature of said wax coating at a temperature above its melting point;
• and
• (d) applying a substantially uniform thin film of liquid coolant to said outside surface of said container, said coolant having a linear velocity substantially equal to said absolute surface velocity of said container and being applied substantially tangential to said outside surface.

A paper cup of the type having a smooth, high gloss coating formed on he outside surface thereof comprising:

• (a) a paper substrate formed in a truncated cone configuration to thereby define an outside surface portion thereof;
• (b) a substantially uniform coating of wax material applied to said outside surface of said cup;
• and
• (c) a substantially uniform film of liquid coolant overlaying and contacting said uniform layer of wax material, said coolant covering a portion of said outside surface of said cup during the formation of said smooth, high gloss coating.

A flat paper web of the type having a smooth, high gloss coating and being produced by the method comprising the steps of:

• (a) advancing said flat paper web along a horizontal path while applying a substantially uniform coating of melted wax material to the top surface thereof;
• (b) maintaining the temperature of said melted wax above the congealing point of said wax material for a time sufficient to cause said wax material to form a uniform liquid film across the top surface of said flat paper web;
• (c) imparting a constant linear velocity to said coated surface of said flat paper web;
• and
• (d) applying a substantially uniform thin film of lqiuid coolant to said coated surface of said flat paper web, said coolant having a linear velocity substantially equal to said linear velocity of said flat paper web and being applied substantially tangential to said coated surface.

A flat paper web of the type having a smooth, high gloss coating formed on the top surface thereof comprising:

• (a) a flat paper substrate;
• (b) a substantially uniform coating of wax material applied to said outside surface of said flat paper web;
• and
• (c) a substantially uniform film of liquid coolant overlaying and contacting said uniform layer of wax material, said coolant covering a portion of said outside surface of said flat paper web during the formation of said smooth, high gloss coating.
