Aspects of the present disclosure relate to a polyolefin composition and processes suitable for use in forming a lid for a hot food or beverage container that has a stiffness comparable to a similar lid made using high impact polystyrene and a density less than water at 23° C.

A container has a base flange on a base, and a lid flange on a lid. When the container is in a closed position the lid flange and the base flange are in juxtaposition and one of the flange edges defines a flange support surface. A lid surface is spaced above an upper base periphery when in the closed position to define a lid volume, and the base section defines a base volume. The flange support surface extends a first distance such that when the volume of the container is loaded with a rated capacity of product and the container is placed in a standing position on a flat surface using the flange support surface and a front base corner as support elements, a center of gravity of the container generates a moment about an axis of the base corner that biases the container in the standing position.

A container assembly for holding containers filled with different items, such as food and cocktail garnishes is disclosed. The container assembly includes a support structure to support a plurality of removable containers. The containers are closed by a cover and sealed by perimeter seals. In illustrated embodiments, the cover includes a plurality of raised or dome shaped portions to provide interior head room for content in the containers. In embodiments described, the perimeter seals are formed of a gasket layer or bands and the support structure includes a support tray and container box.

A package for a medical device such as an intermittent catheter has a case which is closed at one end and open at the other end. A cap is connected to the case by a hinge to permit selectable movement of the cap between an open position, wherein access is provided to the open end of the case, and a closed position, wherein the cap prevents access to the open end of the case. A seal is connected to one of the cap and case. The seal is engageable with the other of the cap and case when the cap is closed to form a barrier that maintains a sterile environment inside the package. The seal can be repeatedly made and broken whenever the user closes or opens the cap, respectively. One of the case and cap has a latch and the other has a receptacle for receiving the latch to releasably retain the cap in a closed position. The latches fit into the receptacle to prevent lateral forces from distorting the cap when the cap is closed. A locking slide may be used to lock the cap to the case.

A package assembly enables a user to adjust package assembly volume and includes a first (static or dynamic) package body and a second dynamic package body. The first package body has an upper body rim. Each dynamic package body provides a dynamic lid volume and has a rim-receiving groove, a lid wall, and at least one resilient portion. The rim-receiving groove is removably attachable to the upper body rim for defining a dynamic package assembly volume with the package body when in a closed configuration with the first package body. The resilient portion extends intermediate the lid wall and the rim-receiving groove and is resiliently actuable intermediate (a) a relaxed configuration for defining a maximum package assembly volume when in the closed configuration and (b) an actuated configuration defining a minimum package assembly volume in the closed configuration.

The tumbler bottle includes a cup having a side wall interior surface and bottom wall a convex interior surface. The cup side wall and bottom wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a first mixing chamber. The tumbler bottle further includes a lid, removably connected with the cup. The lid includes a side wall interior surface and a top wall concave interior surface. The lid side wall and top wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a second mixing chamber. The lid further includes a dispensing outlet and a closure. When coupled together the first mixing chamber and the second mixing chamber are in fluid communication and are configured to uniformly mix a liquid with one or more additives.

The tamper evident container includes a base with a base hinge panel and a lid with a lid hinge panel. A hinge connects the panels. A frangible line extends from an edge of the lid hinge panel to a first point on the panel and then outwardly to the hinge. The frangible line crosses the hinge and extends inwardly to a second point on the base hinge panel. From the second point the frangible line extends to an edge of the base hinge panel. When the container is initially sealed, the frangible line separates upon the application of an upwardly directed force to a first portion of the lid hinge panel while a second portion of the lid hinge panel is held in a fixed position or moved downwardly. The separation of the frangible line creates two grasping portions that can be used to pull the lid from the base.

A connecting structure for a molded paper pulp cup cover comprising a tearable turnover flip cover integrally formed with and arranged on a cup cover plate, where a drinking hole is formed after the flip cover is overturned. The rear side of the flip cover is connected to the hole wall of the drinking hole by at least one turnover stress connection point; the circumferential side edge of the flip cover is connected to the drinking hole by a tear line that comprises a U-shaped section and arc-shaped sections located at the two ends of the U-shaped section; tearable connecting points are formed between the U-shaped section and the arc-shaped sections and a vertical distance from the tearable connecting points to the bottom of the U-shaped section is greater than a vertical distance from the tearable connecting points to the turnover stress connecting points.

A container lid and base assembly includes lid and base stacking features, as well as base chamfers that align with vents provided in the lid. When a plurality of the container assemblies is stacked, the lid and base stacking features nest with each other, while the chamfers align with corresponding vents in the stacked assemblies so that none of the vents is blocked by a next-higher container assembly. The stacking features can be centrally located, and the vents can be peripherally located. A plurality of the container assemblies can have differing sizes and/or shapes, while including mutually compatible stacking features, thereby enabling container assemblies of differing sizes to be stacked without blocking any of the vents thereof. The vents can be holes or “C” vents. The lid and/or base can be manufacturable by thermoforming. The lid and base can be separate, or joined by a hinge.
