A tamper evident container comprises a lid and a base. The lid includes a lid rim having a lid rim flange. The base includes a base rim having a base rim flange. A frangible hinge is formed between a top pinch segment peripherally projecting from the lid rim flange and a bottom pinch segment peripherally projecting from the base rim flange. The frangible hinge is configured to rupture when the container is in the initially sealed arrangement by the application of a pinching force to the top pinch segment and bottom pinch segment that results in the relative vertical movement of the segments toward each other. As compared to the prior art, the container hinges about a frangible vertex instead of hinging about a square-shaped structure.

The invention provides a tamper resistant assembly that that securely contains a valuable material. The assembly has a container for holding the valuable material, an optional carrier that contains the container, one or more cover components that enclose the valuable material in the container, and one or more labels having a plurality of devices that reveal tampering by distortion of at least one of the plurality of devices. The label(s) are positioned so that dislodging a cover component causes a detectable distortion in at least one of the plurality of devices, thereby revealing tampering with the assembly. In one embodiment the label can be affixed partially to a surface of a cover component and partially to a surface of the container or the optional carrier. Also disclosed are methods of detecting tampering and method of manufacturing a temper-resistant assembly. Because the assembly allows a remote validator to validate the assembly prior to providing essential instructions or authorization for conducting procedures on valuable material contained by the assembly, the manufacturer is assured that its procedures are being provided only to authorized persons.

A clamshell container has a lid connected to a base by an integral hinge. The lid has a perimeter projecting member which engages with a peripheral base sealing wall in a closed configuration so that it is difficult for a user to open the container without tearing the lid along a weakened region of material along the hinge. To aid in resisting undetectable tampering, the container has a post which projects from the side wall and extends less than the length of the side wall within the container. The post has an engaging wall which faces towards a base sealing wall and which is spaced from the sealing wall to define a gap which receives the closed lid's projecting member. Distortion of the closed container which tends to urge the lid projecting member away from the base sealing wall engages it with the post engaging wall to resist tampering.

The present disclosure is directed to a child-resistant container which includes a lid having a peripheral flange which defines a lifting tab having top and bottom surfaces. The lid includes a protrusion extending downwardly from the bottom surface of the lifting tab. The container includes a base having an upper peripheral rim and a surface formed in a corner portion of the base between two adjacent sides of the base. The surface includes an aperture to receive the downwardly extending protrusion of the lid when the container is closed forming a child-resistant opening mechanism. The surface is uninterrupted but for the aperture.

A package containing tamper evident features includes a closure for closing the package and an access point that provides access to contents of the package. The closure includes a ring surrounding the closure which is connected to the package, a lid, substantially covering the access point when the lid is closed on the package, a removable tab secured between a portion of the lid and the ring and a plurality of tear off webs between the ring and the lid. The tear off webs are releasably connected between the ring and the lid. Opening of the package by opening the lid requires both removal of the tab from the tube and breaking of the first tear off webs. Removal of the tab forms a window at least partially provided in the lid.

A tamper-evident container generally includes a tray having an opening with a step section formed around the opening and including a first protrusion section that is provided with a first coupling unit with a first perforation line formed therebetween. The first coupling unit includes a coupling trough. A cover includes a concave groove having a bottom and an outside surface engageable with the step section to close the opening. The cover includes a second protrusion section and a second coupling unit between which a second perforation line is formed and projecting beyond the first perforation line. The second coupling unit has a coupling member receivable in and engageable with the coupling trough. Tearing off the first and second perforation lines allows the first and second coupling units to detach from the tray and the cover, respectively with the second protrusion section projecting outside the tray for easy gripping.

A tamper evident and resistant container includes a tray, a cover and a hinge extending from the cover and tray defining a hinge axis about which the tray and cover relatively rotate between a closed position and an opened position. The container further includes a first tab provided on one of the cover or the tray and at least partially defined by a line of weakness. When the cover is in the closed position, a user may pull the first tab to tear the hinge to separate the cover from the tray, wherein the line of weakness at least partially defining the first tab is configured to tear when the first tab is pulled to tear the hinge to separate the cover from the tray.

A food container has a temporary rim formed in one-piece structure on the edge thereof. It has as first sealing rim and a second sealing rim as the surface for a sealing film to be heat-sealed thereon. When the outer rim is torn off, an irreversible tear-off structure on the sealed cover would leave the trace, allowing the consumers and the sellers to decide whether to purchase or dispose of the goods simply by visual judgments; in other words, it has a tamper-proof function. In addition, when the outer rim is removed from the container, the sealing film would detach from the first sealing rim but still stick on the second sealing rim, providing a reusable sealed cover for the container that ensures more safety of food hygiene.

A tamper evident container comprises a lid and a base. The lid includes a lid rim having a lid rim flange. The base includes a base rim having a base rim flange. A frangible hinge is formed between a top pinch segment peripherally projecting from the lid rim flange and a bottom pinch segment peripherally projecting from the base rim flange. The frangible hinge is configured to rupture when the container is in the initially sealed arrangement by the application of a pinching force to the top pinch segment and bottom pinch segment that results in the relative vertical movement of the segments toward each other. As compared to the prior art, the container hinges about a frangible vertex instead of hinging about a square-shaped structure.
