Injection molded polymeric biodegradable container

A biodegradable container, comprising:

• a cylindrical polymeric body element having a body defining an inner cylindrical surface and on outer cylindrical surface wherein a set of exterior ribs are defined on the outer cylindrical surface;
• a polymeric top dome element including a dome portion and a cylindrical neck, the dome portion being joined to the cylindrical polymeric body element and the cylindrical neck defining an inner surface and an outer surface;
• wherein a bottom of the dome portion includes a sealing rim abutting an upper portion of the outer cylindrical surface, the sealing rim being designed to prevent contaminates from entering an interior of the biodegradable container;
• wherein a top of the dome portion defines indentations configured to engage tooling for spin welding of the bottom of the dome portion to the cylindrical polymeric body element;
• a paper sleeve supported by the set of exterior ribs;
• and
• a polymeric cap defining an internal rim configured to be received by the inner surface of the cylindrical neck wherein the polymeric cap includes an outer cylindrical cover configured to extend over the outer surface of the cylindrical neck and wherein the outer surface of the cylindrical neck is smooth and forms a uniform sealing face configured to be substantially flush with an interior surface of the outer cylindrical cover.
