A method of thermoforming a container includes forming a lid having a lid rim, and forming a base including a base rim. The method also includes forming a foldable section that joins the lid rim and the base rim and includes a lid hinge panel extending from the lid rim to a hinge and a base hinge panel extending from the base rim to the hinge. The method also includes forming a frangible line that extends from an edge of the lid hinge panel, across a portion of the lid hinge panel to a first point, from the first point across the lid hinge panel to the hinge, across the hinge, across the base hinge panel from the hinge to a second point on the base hinge panel, and from the second point across a portion of the base hinge panel to an outside edge of the base hinge panel.

A container includes a base and a lid sealingly engageable with the base. The base includes a base hinge panel and the lid includes a lid hinge panel. The base hinge panel and the lid hinge panel are hingedly connected along a hinge line to form a foldable section. The foldable section has a first side edge, a second side edge, and a frangible line that extends between the first side edge and the second side edge. In extending between the first side edge and the second side edge, the frangible line extends across each of a portion of the base hinge panel, the hinge line, and a portion of the lid hinge panel.

In an embodiment, the invention comprises a container apparatus with a lateral stability rail system. At least one rail extends within the lid portion and at least one track extends through the base portion. The rail terminates in a tooth and the track terminates in a pocket. When the container is in a hingedly closed position, the at least one rail nests within the at least one track and the at least one tooth nests within the at least one pocket.

A method of producing a lid including a top plate and a side wall extending downward from a periphery of the top plate, using molds, the molds including a papermaking mold and a drying mold. The top plate is provided with an abutting part abutting against an edge of an opening of a container, while an undercut part to be fitted to a lower part of the edge is formed on the side wall so as to be located below the abutting part. The papermaking mold is provided with suction holes at a level corresponding to a level of the undercut part formed on an inner surface of the side wall. The side wall is suctioned using the suction holes when a molded article is at least in one of several states to form the undercut part in a convex shape on the inner surface of the side wall.

A lid for covering the open end of a beverage container having: an annular base adapted to detachably and sealably engage with the circumference of a drinking edge of a container; an elevated portion projecting upwardly from the annular base; and a spout; the lid arranged and formed such that when in use with a container containing liquid and wherein the lid is securely fitted to the container a user is able to move the spout between a closed configuration which closes the open end of a container such that liquid is substantially prevented from escaping from the container and a drinking configuration which allows a user to drink the liquid contained within the container and also wherein in use the lid is adapted such that a user can squeeze the container or the elevated portion which results in the spout moving from a closed configuration to a drinking configuration.

A bowl assembly has a bowl and a lid. The bowl assembly is adapted to store water or food for a pet. The bowl functions as a container to hold the water or food, while the lid functions in a first configuration to seal the water or food within the bowl. The bowl assembly is convenient to travel with and adapted for use in a vehicle where in the first configuration. The bowl assembly allows for the pet to access the water or food while in a cup holder. The bowl assembly is also stabilized by the lid in a second configuration, where placed on a ground or floor surface.

An example storage chest is provided. The example storage chest may include a box portion and a lid. The box portion may include a front wall, a rear wall, and a floor attached to the front and rear walls to form a primary compartment for storage of items. The lid may include a front panel, a rear panel, and a top panel attached to the front a rear panels. The rear panel may be pivotably coupled to the rear wall of the box portion. The front panel, the rear panel, and the top panel may define a secondary compartment within the lid for storage of items. The secondary compartment may include a lid storage compartment comprising a hingedly affixed door.

A lid structure comprises an edible first part. The first part comprises a bottom portion and an annular wall. The annular wall extends from the periphery of the bottom portion in a direction having an included angle with the bottom portion. The bottom portion and the annular wall define an accommodating space, and the outer periphery of the annular wall is provided with at least one first opening. The lid structure further comprises a second part provided with a third opening and covering the first part, with the accommodating space facing the second part, and the at least one first opening and the third opening being located on opposite sides of the bottom portion, respectively. A portable container comprising a container part and the lid structure is also provided.

A method of forming an undercut which is engageable with an edge, on a side wall of a cover intermediate body using a cover intermediate body and a secondary processing die. In the secondary processing die, a moving inner core has, on the outer surface thereof, a concave shape corresponding to a convex shape of the inner surface of the undercut. The moving inner core is made up of a plurality of core segments which are arranged along the circumferential direction. Each core segment is vertically movable along an inclined surface of a core. When the moving inner core is moved upward, the moving inner core transforms smaller than the inner diameter of the side wall of a cover. The slide core has, on the inner surface thereof, a convex shape corresponding to the concave shape of the undercut.
