A tamper evident container includes a base with a base rim adjoining a base hinge panel and a lid with a lid rim adjoining 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 container lid is provided herein having structurally reinforcing ribs therein. The ribs increase the strength of the lid across a central region thereof. Specifically, the lid can have an outer perimeter and the ribs can be spaced inwardly from the outer perimeter. The inwardly spaced ribs can provide a distinct look for consumer differentiation. Additionally, the ribs can be arcuate so that they generally follow a curvature of the outer perimeter of the lid. As such, a label region within the lid central region is preserved, while the lid is still strengthened by the ribs.

A vacuum formed, tamper resistant container resists deformation of the sides thereof that might otherwise permit access to contents of the container without removal of the lid. Downward protruding lid features reinforce the wall of the container base, and buttress features included in the rim of the base extend from a base flange diagonally downward and inward to the inner rim of a recessed shelf, thereby resisting downward rotation of the wall beneath the lid protruding features. In embodiments, attachment tabs surrounded by frangible boundaries are incorporated in the lid and attached to the base by living hinges, such that removal of the lid requires breaking of the frangible boundaries and detachment of the lid from the attachment tabs. Pucker elements associated with the attachment tabs can cause the attachment tabs to pivot away from the lid when the attachment tabs are detached from the lid.

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.

A package for retaining a food item includes a tray with a base connected to at least one sidewall. The sidewall extends away from the base to a rim to define an inner chamber. The tray is made of a fluid impermeable material to retain fluids in the inner chamber. The package also includes a shelf made of the fluid impermeable material that is removably supported in the inner chamber such that the shelf is spaced apart from the base of the tray to permit an absorbent pad to be positioned therebetween. The shelf is configured to support the food item in the inner chamber separated from the absorbent pad.

Disclosed herein is an injection molded lid for use with a container. The lid includes a lid body and a securing member, respectively made of a first material and a second material. The lid body includes a cover portion and a flange portion disposed around the periphery of the cover portion. One side wall of the flange portion has one or more notches. The securing member includes at least one tab and a frame disposed at the flange portion. The tab extends from the top or bottom of the frame and covers the notch. Also disclosed herein is a container and lid assembly that includes a container and an above-described injection molded lid.

Embodiments of the present disclosure are directed to a biological tissue packaging system, as well as a transport system, and, in some embodiments, comprises a first package, a secondary package, and a tertiary package. Each of the first, second, and tertiary packages is sterilized prior to packaging of a biological tissue therein. The first package comprises a pouch, and a first tray and a first lid configured for removable snap-fit attachment to one another so as to form a clamshell container. The secondary package is configured to contain the first package and interlock therewith. The tertiary package is configured to contain the secondary package and interlock therewith.
