A two-piece tamper-evident band assembly for use with a container and closure combination, where the container has a peripheral collar and the closure has a skirt, is shown. The tamper-evident band assembly includes a breakaway band frangibly connected to a staying ring. The staying ring has decreased flexibility where it connects to the container and closure combination, which prevents the assembly from deforming in a manner that will cause the assembly to fail to indicate that the container has been opened. The tamper-evident band assembly also indicates whether the container has been compromised without requiring modification of the container or the closure and can be applied to existing container and closure combinations that lack a tamper-evident system, allowing the assembly to be used with a variety of container and closure combinations.

A tamper-evident container and method is disclosed. The tamper-evident container includes a base portion and a lid (or cover). In an untampered with state, one edge of the lid is removably connected to one edge of the base portion. Namely, the lid includes a tamper-evident tab, wherein the tamper-evident tab includes a grasping overhanging portion that is flanked by at least one breakable joint and wherein the lid is removably connected to the base portion via the breakable joint of the tamper-evident tab. Further, the tamper-evident container comprises an interlocking interface between the base portion and the lid. A method of using the tamper-evident container is provided.

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.

Disclosed is a tamper-evident container for food storage that uses a round male to female post lock on a single corner. After the cover is locked to the tray base, it requires breaking the corner tray tab to open the container. This tab tear off provides positive evidence of container opening to indicate the container has been opened or tampered with.

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, and 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.
