A plastic package with an open reminder comprises a container and cover; the container being mainly composed of the step portion, horizontal extending surface, outer folding portion, and the protruding portion; the cover being mainly composed of the concave portion, horizontal covering body, and tab; the container and the cover being combined into the plastic package, which forms an open reminder with the tab and perforated line, thereby achieving a function of open reminder that is easy to be observed when the cover has been opened.

The present invention has particular applicability for packaging products and relates to an anti-theft box with a lock mechanism that includes an inner box, with an opening at the first end, a cover plate at the second end and a limiter on the outer wall, and the first end is opposite to the second end; and an outer box. The outer box forms a space, the inner box is installed in this space, the cover plate is outside this space, a locating part is installed on the inner wall of the outer box, and the limiter and the locating part are used in combination to prevent the inner box from being separated from the outer box. The advantage of the present invention is that the safety device in the anti-theft box must be opened to open the anti-theft box to confirm whether the box has been opened.

A one-piece molded food container having a lid, a base and a tamper-evident hinged element connecting the lid and base.

A valve assembly for use with a spout. The assembly includes a slide that includes a side wall, an end wall, a slide flange, and an anti-tamper strap. The side wall includes a dispensing hole. The assembly further includes a sleeve and a cap that includes an inlet, an outlet, and a cap flange. The cap flange includes a strap cavity. The cap is configured to be slidably inserted into a spout, the sleeve is configured to be slidably inserted into the cap, the slide is configured to be slidably inserted into the sleeve, and the anti-tamper strap is configured to be inserted into the strap cavity.

An apparatus includes a tool operable to releasably join a metallic end closure to a metallic container. In one embodiment, the tool is configured to form a thread in the closure and the container. The tool may optionally crimp the closure to the container. Once sealed, the container can be opened by rotating the closure in an opening direction. The closure can subsequently re-close the container by rotating the closure in a closing direction.

Containers with closures are disclosed. A closure may include at least a polymer orifice reducer configured to be permanently secured to a rim of an opening of a container and a flexible tamper evident seal disposed on the topside of the orifice reducer. The flexible tamper evident seal, optionally foil, covers one or more openings in the orifice reducer. Processes for permanently securing a closure to a container, optionally by forming a heat seal between the orifice reducer and container rim, are also disclosed.

A cap for a container closure or closure plug includes a cap top having a top surface and a bottom surface, and an attachment ring extending axially downward from the bottom surface of the cap top under a central portion of the cap top. The attachment ring is securingly engageable with a container closure or closure plug. The attachment ring includes a cam surface extending radially outward from the attachment ring, where the cam surface deflects the attachment ring radially inward upon engagement of the attachment ring with the container closure or closure plug. The cap top and the attachment ring are connected by at least one frangible connection and at least one permanent connection, where the at least one permanent connection retains the cap top in one piece upon breaking of the at least one frangible connection for removal of the cap from the container closure or closure plug.

A composite film for closing a container by sealing the composite film against a circumferential sealing surface of the container or of a cap ring to be connected to the container has a support layer made of a metal film and a sealing layer connected to the metal film. The sealing layer comprises a coextruded layer with a cohesively breaking intermediate layer and adhesion promoter layers arranged on both sides of the intermediate layer. The composite film is suitable for tight sealing against sealing surfaces made of polished tinplate.

A tamper-evident closure for a container with an outer screw thread opening, including an outer cap with a first sidewall and a first top wall and an inner cap with a second sidewall and a second top wall. The inner cap is coaxially nested within the outer cap and has an inner thread. The outer and inner cap have cooperating engagement mechanisms arranged and shaped so when opening the closure for the first time, the inner cap is rotated by the outer cap. The first top wall has a tamper-evident member which is connected to a surrounding region of the first top wall by a frangible component. A protruding element, arranged for breaking the frangible component, is arranged at the first top wall facing the second top wall and/or the second top wall facing the first top wall so as to face the tamper-evident member.

A securable clip includes a first elongated rectangular portion and a second elongated rectangular portion connected along a common edge. The clip includes at least one locking peg, at least one receiving hole configured to receive the at least one locking peg, and a frangible portion. The frangible portion provides a visual indication that the clip has been opened. The releasing of the locking peg prevents the clip from being reclosed, reused, or sealed again.
