A closing element for restricting communication of a substance through an access passage of a body includes a first portion for being removably affixed to the body, the first portion having an inner wall, an outer wall surrounding the inner wall, and at least one bridge connecting the outer wall with the inner wall. The closing element has a second portion for being non-removably affixed to the body and a movable connecting element extending between the first portion and the second portion. The closing element has an unactuated configuration wherein a major portion of the length of the connecting element is located laterally between the inner wall and the outer wall to shield the major portion of the length of the connecting element.

A container cap assembly provides a tamper-evident component for detecting cap integrity on a container includes one or more elongate bridges connecting a tamper-evident ring to a cap. The cap assembly also provides radially-extending links on the cap and the tamper-evident ring to help protect the integrity of the bridges as the cap assembly is applied to a container.

A closure (10) for a container mouth, comprising a cap (15) and a retaining ring (20) for retaining the closure on a container mouth, a tether (45) is provided between the cap side wall and the retaining ring along the circumference of the cap, one end of the tether is fixedly connected to the side wall and the other end is fixedly connected to the retaining ring, in which the tether is connected to the cap by a root (30) and extends from the root in a clockwise direction.

An apparatus and a method are provided for a container cap comprising a plurality of tamper evidence bridges configured to provide evidence that the container cap has been removed from a container by other than a manufacturer of the container. The tamper evidence bridges comprise a small tab of material that extends from a bottom-most edge of the container cap to a neck ring of the container. The tamper evidence bridges are configured to break, or snap, when the container cap is rotated relative to the neck ring. Broken tamper evidence bridges provide readily visible evidence to an end-user of the container that the container cap has been removed by other than the manufacturer of the container. The high visibility of the tamper evidence bridges serves to discourage vendors from attempting to refill and resale of the used containers.

A structure of a mouth plug portion includes a nozzle and a cap, the nozzle includes a first outer protrusion and a second outer protrusion, the first outer protrusion includes a locking surface that locks the cap and a first guide surface spirally extending, the cap includes a cap body and a tamper band provided with a weak portion that can be broken by an external force received from the second outer protrusion during rotation of the cap body, the cap body includes a first inner protrusion and a second inner protrusion, an outer peripheral surface of the nozzle is provided with a second guide surface along which the first inner protrusion and the second inner protrusion can move in an axial direction.

A closure that remains coupled to a container after the upper portion of the closure has been rotatably removed from the container. The closure may include an attachment channel, which includes alternating segments of linear openings and frangible connections. The attachment channel may also include two hinge bridges that remain unbroken when one or more of the frangible connections are broken.

This invention relates to a tethered plastic stopper, having a tamper band positioned around the stopper, a closure shell positioned on top of the stopper above the tamper band, and a linking feature. The linking feature is configured to connect the tamper band to the closure shell, the linking feature including a first end configured to attach to the closure shell, a second end configured to attach to the tamper band, and a central portion. The central portion positioned between the first end and the second end, the central portion being situated furthest from the stopper when compared to the first end and the second end. The linking feature is positioned outside the periphery of the stopper and is configured to allow the central portion to flex during removal of the closure shell from a top of a bottle neck.

A container lid (2) can be removed from a mouth-neck section (106) of a container without the need for a tool. Following the breakage of a breakable thin-walled line (70) in a transition region (52), the breakage of a breakable thin-walled connection wall (68) in a side wall separation region (54) can be started sufficiently smoothly in the container lid (2). For this purpose, the breakable thin-walled line (70) formed in a side wall (10) in the transition region (52) is brought into a form in which at least a part thereof extends obliquely downwardly in a counterclockwise direction.

A screw cap intended to remain attached to a container after opening the container. The cap includes a cylindrical wall having an inner surface including a thread arranged to engage with a thread arranged on a neck of the container, a safety ring extending the cylindrical wall and connected to the cylindrical wall by at least one fracturable connection. A portion of the cylindrical wall forms a strip connected to the safety ring by way of a connecting element arranged to make it possible to displace the cylindrical wall during the unscrewing of the cylindrical wall.

A closure that remains coupled to a container after the upper portion of the closure has been rotatably removed from the container. The closure may include an attachment channel, which includes alternating segments of linear openings and frangible connections. The attachment channel may also include two hinge bridges that remain unbroken when one or more of the frangible connections are broken.
