A rim assembly for a container comprises a frame member (346) having a perimeter corresponding in shape to an opening of a container such that, in use, the frame member is received within the opening and extends around an interior surface of a side wall of the container; a plurality of securing tabs (394) hingedly connected to the frame member (346), each tab (394) including an engagement member (396); sealing means configured for repeated sealing engagement with a lid of the container; and retaining means (399), wherein each of the securing tabs is movable between a first position in which the engagement member is disengaged from an aperture (317) in the container side wall and a second position in which the engagement member (396) is engaged with one of the apertures (317) in the side wall, and wherein the retaining means is configured to retain the securing tabs in the second position such that the rim assembly is secured to the container around a top edge of the side wall.

Disclosed are rigid multi-compartment recloseable packages. A package may comprise a rigid tray comprising a product surface to hold food products. The tray may comprise a raised lip along a perimeter of the product surface to laterally secure the food products thereon. The tray may have a tray skirt horizontally extending outward from a top edge of the lip, and dividing features upwardly extending from the product surface to form distinct compartments on the product surface for receiving the food products therein. Furthermore, such an exemplary package also comprises a recloseable rigid lid having an upper surface substantially coextensive with the product surface, and at least one sidewall downwardly extending from the upper surface. The lid may also comprise a lid skirt horizontally extending outward from a bottom edge of the at least one sidewall, where the lid skirt is coextensive and complimentary in shape with the tray skirt.

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.

Inhibiting spoilage of items is achieved by providing a container having an environmentally controlled storage compartment sealed form the external atmosphere and a reaction medium in a separate compartment in fluid communication with the storage compartment.

A container suitable for hot foods includes a base having a wall that is slanted or curved outward from its bottom, and a lid having a rim attachable to the base, an intermediate region that rises upward, and an inner region that does not rise as high, such that when an identical container is stacked thereupon, the upper base is entirely supported by the lower lid intermediate region, forming a gap space between the lower lid inner region and the upper base. One or more ventilation holes in the lid inner region, together with channels in the base wall and/or intermediate region, allow vapor from the lower container to escape from the stack through the ventilation holes, gap space, and channels. The intermediate region can be shaped to support an upper container mainly by compressive forces, further enhancing stacking tolerance to weight and heat.

A lid for a container includes snap-fit hooks for interlocking engagement in complementing latching openings of an outwardly projecting flange of a jacket of the container, and stacking parts disposed on a lower side of the lid close to the periphery for form-fitting engagement in complementing stacking parts on an upper side of a further said lid, when the lids are stacked. The lower side of the lid and the upper side of the further lid have each a central region that forms a contact area via which compressive forces are transmissible in the presence of a contact between the contact areas of the lower side of the lid and the contact area of the upper side of the further lid.

Systems and methods for providing compostable food containers that preserve the quality of a food product for an extended duration of time, and which optionally allow for cooking of the food product therein. In some implementations, the food containers are sturdy, stackable, insulating, and require minimal or no manual labor to assemble. In some implementations, the food container includes a base and a cover which cooperate to form a closed chamber for supporting, protecting, insulating and optionally cooking a food product, such as a pizza. The base and cover may each be formed of a single layer of material including, but not limited to, molded sugarcane fiber (bagasse), molded wood fiber, molded bamboo fiber, molded paper or plastic.

Strawless drinking lid for a container, having a mounting portion defining an outer perimeter, and a perimeter wall disposed inwardly from the mounting portion. The perimeter wall extends upwardly relative the mounting portion and has an outer surface facing the mounting portion and an inner surface opposite the outer surface. The strawless drinking lid further has a center portion extending inwardly from the inner surface of the perimeter wall and a raised drinking portion extending upwardly from the center portion. The drinking portion has a front section and a back section with an upper surface therebetween. The front section of the raised drinking portion has a front edge proximate the inner surface of the perimeter wall, and the back section of the raised drinking portion has a back surface extending upwardly from the center portion. The raised drinking portion has a closed configuration and an open configuration.

A cover for a container that includes a lid portion and a collar element. The lid portion having a main body section surrounded by a peripheral sealing shoulder. The collar element having a peripheral collar sealing shoulder that includes a collar groove and wherein the lid portion is connected to the collar portion through a hinge element. The lid portion, collar element and hinge portion are formed as a unitary structure and the lid portion articulates from an open positon in which it is spaced apart from the collar element to a closed position wherein the peripheral bead sealing shoulder of the lid portion engages with the peripheral collar sealing shoulder of the collar element.

A container includes first and second shells sealingly engageable with each other. Each shell includes a rim, where the rim of each shell includes a rim bead having an inner wall and an outer wall. The inner wall and the outer wall of the rim bead of the second shell frictionally engage the inner wall and the outer wall, respectively, of the rim bead of the first shell to sealingly engage the rims. The container also includes hinge panels each extending outwardly from one of the rims of the first and second shells. The hinge panels are hingedly connected to each another along a hinge line to form a foldable section that includes the hinge panels and the hinge line. The foldable section has a frangible line formed on each of the hinge panels, where the frangible line extends transversely between the hinge panels and transects the hinge line.
