A plastic container capable of assuming a loading state, an initially sealed state and an opened state comprises a lid including a lid rim and a base having a base rim. The lid rim sealingly engages with the base rim. A projecting portion has an accordiated section and a pull tab that projects outwardly from the lid. The accordiated section has at least one pleat. The projecting portion includes a frangible bridge. When the plastic food container is in the initially sealed state, the accordiated section has a first length and a first orientation relative to the projecting portion. When the container is in the initially sealed state and a first pulling force is applied to the pull tab, the frangible bridge ruptures. When the frangible bridge ruptures and before the lid is separated from the base, the container is in a tab-employed state in which the accordiated section springs outward and has a second length visibly longer than the first length.

A storage device for insertion within a cavity in a mannequin component, the storage device including a body having a receptacle for receiving items associated with said mannequin component, and a lid for closing the receptacle to enclose the items within the storage device.

A pull-tab sealing member for a container providing a foamed polymer layer positioned within the sealing member for effective heat sealing to the container together with a lower laminate below a tab capable of tearing to provide a tamper evident structure below the tab.

A self-aligning, pivotally engaging container sealing device is provided. The device comprises a base, a sealing head including an upper die member pivotally mounted relative to the base, and a lower die member supported by the base for free pivotal and vertical movement relative thereto. The lower die member is biased generally upwardly by a spring or other biasing mechanism, while permitted to tilt substantially freely about a generally horizontal axis. The device may be manually actuated by pivotally lowering the sealing head to operatively engage the die members. Initial contact by the descending upper die member on a part of the lower die member impels the lower die member to tilt into parallel alignment with the upper die member, before any significant force from the biasing member is transmitted through the lower die member to the upper die member to clamp and form a seal between a container flange and container cover located between the upper and lower die members.

An expandable and collapsible lid system and method thereof. The system includes at least one container including an opening and at least one corresponding lid. The lid may be operable between an expanded state, a middle state and a collapsed state. The lid includes a flange having a circumscribing lip for releasably sealing the opening of the container and concentric segments. Each concentric segment may be flexibly coupled to an adjacent concentric segment, inner-diameter to outer-diameter, a diameter of the concentric segments decreasing inversely with the distance of the concentric segment from the flange, a concentric segment having a largest diameter being flexibly coupled to the flange. When positioned atop the container, the lid increases a storage volume of the at least one container in the expanded state and forms a pool within the container for nesting of a further container when in the collapsed state.

Containers are described that allow a consumer to see inside the container and to more easily access the products. One form of the container includes a base member with a lid defining a window. A flexible laminate with a peelable flap portion is attached to the lid to provide access to the products inside. The flexible laminate includes a first film layer laminated to a second film layer. The first film layer includes a first cut line defining a peelable flap portion and the second film layer includes a second cut line offset from the first cut line that defines an opening into the container. First and second reclose surfaces defined between the cut lines on the corresponding film layers include pressure-sensitive adhesive to allow the container to be re-sealed via movement of the peelable flap portion back into engagement with the flexible laminate remaining with the container.

Disclosed is an airtight container in which a lid is easily opened by the principle of the lever thus preventing broth from splashing out when the lid is opened. The airtight container includes a container body having a latching bump and a bent flange, a rotating knob connected to the flange and having an opening-closing plate and a step portion, and a lid having a latching protrusion, a downwardly bent flange and a lid extension portion, wherein, when the rotating knob is just rotated upward in a state where the lid is coupled to the container body, the opening-closing plate lifts the lid extension portion by the principle of the lever while the step portion prevents the lid extension portion from spreading outwards, thereby allowing the latching protrusion to be released from the latching bump and the lid to be opened from the container body.

A food container is disclosed that includes a food compartment and a seal-on cover. The food compartment has an outer rim that circumscribes a volume. The food compartment outer rim has tear tab guides that extend outward from the rim. The seal-on cover has a peripheral edge with two portions, the first portion is connected to the rim and the second portion is not connected to the rim and extends past the outer rim forming an overhang. The extended tear tab guides are located adjacent to the overhang and direct the user as to where the tear line begins at the overhang and extends to an opposite side of the peripheral edge. When a user pulls on the overhang, the seal-on cover tears along the tear line and exposes a portion of the volume.

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.

A packaged food material includes a first container, a second container, and a food material. In the packaged food material, the opening portion of the first container is not closed. The packaged food material is such that when two or more packaged food materials are stacked, a bottom portion of the first container of one of the packaged food materials is located in the first container of another packaged food material.
