Disposable containers for storing contents, such as food products. The containers include a cover material disposed about a periphery or an outer surface of the container in a folded configuration and deployed, when pulled out by a user, in an amount and shape sufficient to cover at least the opened periphery of the container.

A base structure for a container, the base structure including a base volume; and a flange defining an opening of the base volume, the flange extending from the base volume about the perimeter of the base volume; the flange including at least one projection, wherein the at least one projection extends away from the base volume, and further wherein the at least one projection extends around a majority of the perimeter of the base volume.

A container including a paper-based cradle, a paper-based insert, and a thermoplastic film. The cradle has exterior corner panels that form a transition between the exterior end panels and exterior side panels. The cradle and insert are held together by the thermoplastic film that is thermoformed into conformance with the cradle and insert. The exterior corner panels at the junctures between the exterior end panels and exterior side panel can reduce the potential for defects in the thermoformed thermoplastic film.

A method for forming a container having an injection-molded feature. The method includes obtaining a blank, forming the blank into a three-dimensional article having at least one sidewall, and forming the injection-molded feature extending around the perimeter of the article. The injection-molded feature comprises an anchor portion and a flange portion. The anchor portion is in contact with an interior surface of the at least one sidewall and the flange portion extends from the anchor portion outwardly from the at least one sidewall.

A container having venting means and a method for sealing a lid to the container without damaging or weakening the container are disclosed. The container, such as a cup, includes venting means in the interior surface of the container side wall generally adjacent a lid seal to allow air that would otherwise be forced into and become trapped in the container when the lid is sealed to the lid seal to vent from the container to prevent weakening of, damage to or ultimate failure of the container.

A tool and method for forming a container from a construct. The tool comprising a cavity for receiving a construct, a core operatively associated with the cavity and being operable to move into the cavity, an injection cavity for receiving injection-molding material and directing injection-molding material around at least a portion of the perimeter of the construct, and a clamping feature. The clamping feature is operatively connected to at least one of the cavity and the core and is for clamping a peripheral portion of the construct as the core moves into the cavity to form the construct into the container.

A container including a paper-based cradle, a paper-based insert, and a thermoplastic film. The cradle has exterior corner panels that form a transition between the exterior end panels and exterior side panels. The cradle and insert are held together by the thermoplastic film that is thermoformed into conformance with the cradle and insert. The exterior corner panels at the junctures between the exterior end panels and exterior side panel can reduce the potential for defects in the thermoformed thermoplastic film.

Embodiments of the invention overcome the shortcomings of prior technologies by infusing nanocellulose in a fibrillated form to enhance the properties of cellulose pulp. These properties may include, for example, the mechanical and barrier properties, i.e., tensile strength, liquid, and gas impermeability such as oxygen, carbon dioxide, and oil, can be improved substantially. Another embodiment of the invention further provide a fibrillated cellulose composite material that include properties of being a strength-enhancing agent, an oligomer, carboxylic acid, plasticizer, an antimicrobial agent, water repellant, oil repellant, and/or a transparent composite.
