Tamper-evident plastic container comprises a base portion having a sidewall and a base flange extending outwardly from at least a portion of the sidewall, as well as a lid portion having a lid tab joined to the base flange by a hinge, wherein the lid portion has an open position and a closed position. The lid portion is configured to lockingly engage the base portion in the closed position. One of the base flange or the lid tab has a non-linear path of weakness formed therein to define a frangible connection, wherein the frangible connection is configured to be ruptured to initially open the lid portion from the closed position. The non-linear path of weakness is spaced from the hinge to define a tamper indicator region between the non-linear path of weakness and the hinge, wherein the tamper indicator region remains joined to the hinge after the frangible connection is ruptured. Methods of containing a product in a tamper-evident container are also disclosed.

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 tamper-evident container has a lid with a rim with a bead mating with a groove in a base rim. The rim bead is interrupted by a tab wall which does not engage the base. The lid has a first flange portion which overlies a base flange. The base and lid first flange portions extend outwardly about the same amount. At the tab, a second portion of the lid flange extends substantially outwardly beyond the base flange. The flange second portion is connected to the first portion on both sides of the tab by weakened lines of material which extend cut lines through the tab front wall. The tab second flange portion is engageable to sever the weakened lines of material and pivot the tab upwardly to remove the lid, thus deforming it and evidencing tampering should the lid be replaced on the base. Base vents reduce ballooning when closed.

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.

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.

A cover for a container includes a plurality of panels extending at least partially around an interior of the cover. The plurality of panels includes a central panel, at least one side panel foldably connected to the central panel, and at least one end panel foldably connected to the central panel. At least one of the at least one side panel and the at least one end panel includes an opening configured to receive a portion of the container. The opening includes an engagement edge for engaging the container. The cover also includes a handle foldably connected to the central panel.

A cup lid includes a main body that closely receives a paper cup and a lid connected thereto by a connection section. The lid is arranged to close the paper cup and is attached to the main body. The main body includes a hollow annular body that is provided with a raised ring engagable with a coupling groove of the lid. The main body includes a support section extending from an inner circumference thereof to fix the paper cup therein. The main body is provided, on an outer circumference thereof, with handle sections for holding and lifting by a user and thermal insulation sections positionable on a cup body of the paper cup for thermal isolation and protection against burning when held by the user.
