A closure comprising a base body with a circumferential recess foreseen to receive a tamper band connected to a top cover. The circumferential recess comprises at least one circumferential protrusion extending in a radial direction into the recess which comprises at least one pillar extending in the radial direction into the recess, tamper band comprises at least one circumferential undercut foreseen to interact in a mounted position with the circumferential protrusion of the circumferential recess. The tamper band comprises at least one notch foreseen to receive at least one pillar arranged in the circumferential recess.

A spout cap is a spout cap for closing a mouth portion of a spout main body, and includes a cylindrical body portion made of resin, and a sealing film joined to the body portion, in which the sealing film has a thermal bonding layer which is configured to join to a distal end surface of the mouth portion when the mouth portion is closed.

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.

The invention described herein relates broadly to closure assemblies, and methods of use and manufacture thereof. More particularly, certain embodiments relate to assemblies and methods for closing an opening defined by a spout provided on a flexible container utilising a capping member having a plugging portion and a substantially fracturable retaining skirt. Embodiments provide may an adequate seal for the contents contained within bags against the significant pressure placed upon the closure by the often weighty and voluminous contents of the packaging. Furthermore, the closure may be easily and comfortably removable by a user whilst managing the handling of the bag.

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.

Provided is a plugging-type resin cap which can sufficiently seal a container and in which, upon uncapping of the container, a restraining band loosens after the pressure in the container is released without the application of an excessive force. A plugging-type resin cap (100) includes a restraining band (130), a tab (140), and engagement projections (151). The restraining band (130) has an arcuate restraining portion (131), stoppers (132), and an upwardly projecting portion (133). The stoppers (132) are formed to extend radially outward from the circumferential both ends of the restraining portion (131). The engagement projections (151) are disposed over an outer side surface of a skirt wall (120) in the vicinity of the circumferential both ends of a tab (140). The stoppers (132) and the engagement projections (151) are formed to be fittable with each other.

The invention relates to a locking cap for a container comprising a neck, intended to block a stopper in the neck of the container and comprising: an external body having a breakable part, a cage that is configured to fit into and lock axially in the external body, and having a breakable zone, the cage further comprising: an upper ring, a plurality n of branches that are connected to the upper ring and define therewith a generally cylindrical shape, n/2 first bridges and n/2 second bridges, each interconnecting two adjacent branches, at least one opening tab, which is supported by a second bridge, which is inclined toward the outside of the cage and is oriented toward the upper ring, the opening tab being adjacent to the breakable zone, which is located on the second bridge.

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.
