A closure includes first and second closure portions. The first closure portion includes a top wall portion and an annular skirt portion that includes an internal thread formation. The second closure portion includes a tamper-evident band being at least partially detachably connected to the skirt portion by a frangible connection. The tamper-evident band includes first and second portions connected via a bending area. The second portion extends generally upwardly from the bending area towards the top portion and is located inwardly from the first portion of the band. The second portion of the band includes a tab portion and an extension portion. The extension portion is located further from the bending area than the tab portion. The average thickness of the tab portion is greater than the average thickness of the extension portion. The extension portion extends continuously around an entire inner circumference of the closure.

A closure for a container includes a closure shell having a first interior surface, a tamper evident band having a second interior surface, and a flexible hinge. The flexible hinge includes a first end, a second end, and a gathered portion located between the first and second ends. The first end is coupled to the closure shell and the second end is coupled to the tamper evident band. At least a portion of the gathered portion extends radially inward with respect to the interior surface of the closure shell. The flexible hinge permits the closure shell to be opened and remain tethered to the tamper evident band. The closure may further include a retaining bead or ratchets to keep the tamper evident band attached to the container.

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 closure device for a container having a neck including an annular flange, the closure device comprising: a cap body; a tamper evident (TE) band positioned below the annular flange when assembled in the container; a first hinge and a second hinge defined on the cap body; a leash connected to the TE band, the first hinge and the second hinge; the leash allowing for the cap body to be separated from the TE band during opening, but to remain connected thereto via the leash; a tongue protruding from the cap body between the first and second hinges; when the cap body is actuated from a closed configuration relative to the neck to a fully open position: the leash is configured to retain the cap body to the TE band; an interaction of the tongue and the neck is configured to retain the cap body in the fully open position.

An apparatus and methods are provided for a container closure for sealing contents within an interior of a container. The container closure comprises a closure portion that is coupled to a tamper evidence band by a single anchor. The anchor is configured to keep the closure portion coupled with the tamper evidence band. The closure portion threadably engages with a finish portion of the container and seals contents in the interior of the container. The tamper evidence band remains engaged with the finish portion when the closure portion is removed from the finish portion. A multiplicity of thin connections between the tamper evidence band and the closure portion break apart when the closure portion is untightened from the finish portion. The anchor remains unbroken and allows the closure portion to be tilted away from the finish portion.

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.

This invention is an improved stopper for a bottle with a tethered plastic stopper where its closure shell remains attached to its tamper band after bottle opening. The tethered plastic stopper includes a closure shell that remains attached to its tamper band after the bottle is opened through a linking feature. The invention also includes a method for making a stopper.

A tamper-evident container closure (10) is provided and comprises a base (15) and a lid (20). The base and lid are connected together by a hinge (25) so that the lid can be moved between a closed position and an open position. The base is attachable to a container neck. Generally opposite the hinge the lid includes a retention member (35), the retention member includes or defines a window (39) and includes a retention portion for engagement with a cooperating portion on the closure and/or on a container neck for holding the lid in a closed position. The closure includes a tamper-evident member (40) at least part of which moves into or out of view with respect to the window to indicate opening of the closure.

Described is a combination of a closing cap (1′) for a container (2) and a neck (201) of the container (2), wherein the cap (1′) comprises a lateral wall (3) extending about an axis (Z) and a transversal wall (4) positioned at an end of the lateral wall (3), a separation line (5′) of the lateral wall (3) defining a retaining ring (301′), configured to remain anchored to the neck (201) and a closing element (302) to open or close the container (2). The separation line (5′) extends about the axis (Z) and is circumferentially interrupted so as to leave the retaining ring (301) and the closing element (302) joined together. The retaining ring (301′) comprises a retaining portion (303), configured to engage internally with a locking ring (202) of the neck (201), the latter projecting from an outer surface of the neck (201) and extending in a direction parallel to the axis (Z) between an upper end (202c) and a lower end (202b). The retaining ring (301′) comprises a joining portion (305) which allows the retaining ring (301′) to be joined to the closing element (302), a first connecting band (306) and a second connecting band (307), which connect the joining portion (305) to the retaining portion (303), and a tab (308) positioned between the first connecting band (306) and the second connecting band (307). The connecting bands (306; 307) are made by an incision line (7′) which comprises a first lateral stretch (702′) and a second lateral stretch (703′) wherein the first lateral stretch (702′) and the second lateral stretch (703′), when the closing element (302) is in a closed condition, are arranged in such a way that when the closing element (302) is in an open condition and the connecting bands (306, 307) keep the closing element (302) connected to the retaining ring (301′), the tab (308) can rest on the neck (201) beyond the upper end (202c) of the locking ring (202) towards the dispensing opening (203).

The present disclosure describes bottle closure assemblies which are made at least in part with a polyethylene composition having good processability, good organoleptic properties and good dimensional stability. The bottle closure assembly includes a cap portion, an elongated tether portion, and a retaining means portion. The retaining means portions engages a bottle neck or an upper portion of a bottle. The elongated tether portion connects at least one point on the cap portion to at least one point on the retaining means portion so as to prevent loss of the cap portion from a bottle.
