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.

An anti-theft container has a body and at least one connecting and recognizing assembly. The body has a case and a lid mounted to the case. The at least one connecting and recognizing assembly is mounted to the body and has a connected portion and a linking portion. The connected portion is disposed on the case and has a limiting recess, a recognition element, and a tear line. The limiting recess is formed in the connected portion and has a limiting surface disposed obliquely. The limiting surface makes an upper space of the limiting recess smaller than a lower space of the limiting recess. The recognition element is disposed on a bottom of the connected portion. The tear line is located on a circumference of the recognition element. The linking portion is disposed on the lid, received in the limiting recess, and disposed against the recognition element.

A container includes a container body with a projection and a cap with a cover member, an inner member, and an outer member. The inner member is threadably engaged to the neck of the container body and is supported for movement between a first threaded position and a second threaded position relative to the container body. The outer member depends from the cover member and extends at least partly about the inner member and an axis. The outer member includes a tamper-evident member that includes an abutment member configured to engage with the projection to limit movement of the cap from the first threaded position to the second threaded position. Also, the tamper-evident member is permanently deformable to disengage the projection and allow movement of the cap from the first threaded position to the second threaded position.

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.

It is provided a cap (10) for closing an opening (41) of a container (30), comprising a mainly tubular skirt (12), wherein the skirt (12) comprises a bayonet notch (26) for guiding a pin (28) of the container (30), wherein the skirt (12) comprises a guiding rim (38) running in axial direction and in circumferential direction towards the bayonet notch (26) for guiding the pin (28) of the container (30) into the bayonet notch (26). When the cap (10) is mounted to the container (30), the pin (28) may slide along the guiding rim (38) towards the bayonet notch (26) even at an originally significant displacement in circumferential direction, so that a facilitated mounting of a cap (10) to a container (30) with a bayonet mount is enabled.

The present invention is directed toward a container closure that prevents accidental initial opening of a container. The closure mechanism includes at least one temporary interlocking mechanism having a two part fastener that engages the moveable part of the closure with the fixed part of the closure. The temporary interlocking mechanism is invisible when the container is closed. It is positioned in a location different from the location of the orifice of the closure or from the path that the liquid follows during dispensing. This temporary interlocking mechanism includes at least one element that breaks or irreversibly deforms during the initial opening of the container. The additional force required to break or to irreversibly deform the breakable or irreversibly deformable element of the temporary interlocking mechanism during the first opening mitigates the risk of accidental opening during manufacturing, shipment or storage of the goods. Once broken or irreversibly deformed during the first opening, the interlocking mechanism does not interfere with the subsequent opening and closing cycles of the container by the consumer.

A system and method for storing, shipping, and displaying produce in a box which has a tamper-evident closure. The box may be formed of folded cardboard and a transparent plastic lid which engages top edges of the box. The lid has a plurality of tabs around its periphery that may be bent and inserted into slots or notches formed in the box edges, and then expand to a larger relaxed size. The slots or notches have perforated lines enabling the lid to be ripped upward to open the box, thus indicating that the container has been tampered with.

A device adapted to provide evidence of tampering. The device comprises a sleeve and an insert that is positioned within the sleeve. The insert comprises a flap that is movable between a closed position and an open position. In particular, the flap is adapted to move from a closed position to an open position when the position of the sleeve relative to the insert is changed a predetermined amount to try to open the container. As a result, an open position of the flap would readily indicate tampering to a user. A system comprising a tray adapted to receive at least one said device is also provided.

A flip-top dispensing closure is provided. The closure comprises a base and a lid. The base is attachable to a container neck and includes an integral spout. The lid comprises a fixing ring and a cap. The fixing ring is attachable to the base and the cap is hingedly attached to the ring. The closure is provided with tamper-evident means comprising first and second parts which are initially frangibly connected to each other within the lid, and upon first opening of the cap the first and second parts are separated, one of the parts being retained by the cap and the other of the parts dropping onto the base.

The present invention relates to a tamper evident produce container having two front corners. The produce container includes a receptacle, a lid and a pair of frangible tabs. The receptacle has a mouth circumscribed by a first flange. The lid is associated with the receptacle to close off the mouth. The lid has a second flange. Each frangible tab is joined to either one of the first or second flange at or in close proximity to one of the two front corners by an area or line of weakness. Each frangible tab includes a first locking formation which is adapted to interlock with a second locking formation provided on or in the other of the first or second flange when the lid is positioned on the receptacle to close off the mouth.
