Claims25
A container for holding materials comprising:
- a thermoformed molded pulp shell body comprising (1) a hinged first pulp shell and second pulp shell that are foldable to form an enclosed body, or (2) multiple pulp shells including a first pulp shell and a second pulp shell joined together to form the enclosed body;
- wherein the thermoformed molded pulp shell body is configured to contain materials within the enclosed body;
- wherein the first pulp shell forms a top part of the pulp shell body, and the second pulp shell forms a bottom part of the pulp shell body;
- an orifice in the top part of the pulp shell body configured to permit passage of the materials through the orifice into or out of the thermoformed molded pulp shell body, wherein at least a portion of the first pulp shell forms an overlap or an attachment with the second pulp shell;
- and
- a separate structure removably coupled to the thermoformed molded pulp shell body at a neck of the thermoformed molded pulp shell body, wherein at least a portion of the structure comprises (a) a support ring that contacts an interior surface of a vertical portion of the neck or (b) an attachment structure having walls to be registered on both an inner side and an outer side of the vertical portion of the neck.
A container for holding materials comprising:
- a molded pulp shell comprising a plurality of pulp shells including comprising a top part and a bottom part that are joined together, or are hinged and foldable to form an enclosed body, wherein the molded pulp shell body is configured to contain a separable liner contained within the enclosed body, wherein the separable liner includes an edge that contacts a flange of a neck of the container and the separable liner is secured to the container when a reclosable lid is locked to the container to be in contact with the edge of the liner;
- molded pulp threads integrally formed on the molded pulp shell;
- and
- a threaded closure configured to mate with the molded pulp threads, the threaded closure having an internal protruding feature configured to contact an inner surface of the liner when the threaded closed is mated with the molded pulp threads.
