A container closure and methods are disclosed for providing visible evidence of removal of the closure from a container after installation by a manufacturer. The closure includes tamper evidence bridges comprising small tabs of material that extend from a bottom-most edge of the closure to a tamper evidence ledge of the container. The bridges break when the closure is rotated relative to the tamper evidence ledge, thereby providing readily visible evidence that the closure has been removed after installation by the manufacturer. In some embodiments, a tamper evidence closure engages with threads of a finish of the container. Cam locks around the perimeter of the tamper evidence closure are permanently flared by cams on the finish during loosening of the closure. Outward flaring of the cam locks provides a visual indication that the tamper evidence closure has been loosened after installation by a manufacturer.

A container closure of synthetic resin is for a container having a mouth-and-neck portion with an external thread on an outer periphery thereof and an engaging jaw portion positioned below the external thread. The container closure includes a body and a tamper evident skirt portion, and is configured to not be entirely separated from the mouth-and-neck portion of the container even after unsealing the container at the mouth-and-neck portion. At least in an angle region in which a protruding piece on a skirt wall of the body is present, an extending portion is defined at an engaging piece on the tamper evident skirt portion. When the container closure is mounted on the mouth-and-neck portion of the container, the extending portion of the container closure is positioned between the engaging jaw portion of the mouth-and-neck portion of the container and the tamper evident skirt portion of the container closure.

A 2-piece closure includes a cap having a first skirt perpendicular to, and extending downwardly from, a first circular top wall. The first skirt includes a groove and a first anti-rotation formation. A tamper band attaches to the first skirt by frangible members. A cap cover includes a second skirt extending downwardly from a second circular top wall. The second circular top wall and the second skirt define an interior having a groove engagement formation and a second anti-rotation formation. The cap cover encloses a portion of the cap, with the groove engagement formation and the groove engaged. The first and second anti-rotation formations interact to restrict rotation of the cap cover relative to the cap.

A cap (1) for a container comprises: a body (2), configured to be coupled and uncoupled relative to the neck of the container and including an internally threaded side wall (21), which extends around a longitudinal axis (A), and a transverse wall (22); a tamper evident ring (3), including a retaining element (31), configured to engage a locking member on the neck of the container, and a joining portion (32), where the tamper evident ring (3) is joined to the cap body (2), the joining portion (32) being configured to be torn along a perimeter surrounding the longitudinal axis (A) in response to a movement of the body (2) away from the tamper evident ring (3), wherein the cap (1) comprises a connecting window (4) including a connecting band (40) and a film (400) which is thinner than the connecting band (40).

A spout assembly includes a spout and a cap. The cap includes an inner ring having an outer peripheral surface provided with a first region with a first outer diameter and a second region with a second outer diameter. The spout includes a side wall having an inner peripheral surface provided with a first region having a first inner diameter and a second region having a second inner diameter. When the cap is threadably engaged with the spout, the first region of the inner ring is in close contact with the first region of the side wall of the spout throughout the circumference, and the second region of the inner ring is in close contact with the second region of the side wall of the spout throughout the circumference.

The invention relates to a tamper evident cap for removable screwing onto a fluid outlet provided on an enteral fluid source, the cap includes a tamper evident feature comprising a deflectable element configured to be momentarily deflectable in a longitudinal direction by a deflecting element provided on the fluid outlet as the cap is screwed onto the fluid outlet, and wherein the deflectable element is configured to be permanently deflected outwardly in relation to the longitudinal axis by the deflecting element as the cap is unscrewed from the fluid outlet to provide a visual indication that the cap has been unscrewed.

Embodiments of a tamper-evident closure are disclosed which prevent unauthorized access to a container and its contents, deterring adulteration or introduction of counterfeit product. In one embodiment the tamper-evident closure can be fitted to an associated container and closure, and includes a portion which is removed by fracture of the tamper-evident closure to gain access to the container closure. In another embodiment, an arrangement of wedge-like tongues permit fitment of the tamper-evident closure to associated container for temper-evidence. In another embodiment, the tamper-evident closure is joined by frangible bridges to the container closure to provide the desired tamper-evidence. In another embodiment, the tamper-evident closure is movable axially of the associated container closure to thereby provide evidence of removal.

The first and second anti-rotation formations interact to restrict rotation of the cap cover relative to the cap.

The present invention discloses a tethered stopper affixed to a bottle neck finish. The stopper includes a closure shell, a tamper band, and a strip connecting the closure shell to the tamper band at the perimeter of both the closure shell and the tamper band. The bottle neck finish includes a transport ring having a retaining feature configured to receive and retain the strip of the stopper when the closure shell is removed from the bottle neck finish. Also discloses is a method for securing the tethered stopper within the tamper band.
