A capsule for covering the top of a bottle includes a lower portion configured to wrap about a neck of the bottle, an upper portion connected to the lower portion and configured to be removed from the lower portion to expose a top of the neck, and a trench formed about a periphery of an upper edge of the lower portion. An assembly used to form the trench in the capsule includes a housing, and a blade extending outwardly from the housing.

An anti-counterfeit bottle cap, having a body (10) and a safety ring bell (20), and a slit (30) in between; an anti-theft mechanism (40) is provided within the slit (30); the anti-theft mechanism (40) has upper rods (41), lower rods (43) and a tear ring (42) in between; upper ends of the upper rods (41) are connected to the body (10), lower ends of which are connected to the tear ring (42); upper ends of the lower rods (43) are connected with the tear ring (42), lower ends of which are connected with the safety ring belt (20). The tear ring is subject to irreversible plastic deformation after the body (10) disengages from the bottle mouth. Therefore, the tear ring (42) cannot be restored. The torn and broken upper rods (41), lower rods (43) or tear ring (42) cannot be glued back to its/their original position(s).

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.

A closure may have a top wall and a side wall depending from the top wall. A plug seal device may depend from said top wall within the side wall. The plug seal device may have an upper section, a lower section, and a sealing section proximate the boundary between the upper section and the lower section. The sealing section is operable such that when the plug seal device is inserted in an opening to an inner cavity in a container, the sealing section engages with an inner container surface to provide a seal between an inner cavity of the container and the external environment.

Disclosed is a metallic cover cap for sealing a metallic bottle, comprising a gasket provided with a flat central zone and an annular zone which includes an outer rim and an inner rim that are separated by a notch, such that the outer rim extends axially, continues circumferentially, and includes: a first surface; a second surface with a flat portion and a concave portion radially opposite the notch; and a third flat surface that extends between the first and second surfaces, and the inner rim extends axially, continues circumferentially and spaced radially inwards of the first rim, and includes: a first flat surface opposite and perpendicular to the flat zone; a second concave surface radially opposite the notch; and a third flat surface between the first and second surfaces that is inclined toward the notch.

A separate bottle cap comprising a bottle body connector (1), an outer cap (2), an anti-backflow assembly (3) and an inner cap (4), wherein the bottle body connector (1) is a hollow cylinder, a lower end thereof is fit and connected to a bottle body, the anti-backflow assembly (3) is provided between the bottle body connector (1) and the inner cap (4), a lower end of the outer cap (2) is sleeved on the anti-backflow assembly (3) and locks an inner wall of the bottle body connector (1), and the outer cap (2) is provided on the inner cap (4), wherein the anti-backflow assembly (3) comprises a piston anti-backflow water blocking member (31) and a water sealing connector (32), and the piston anti-backflow water blocking member (31) is movably connected with the water scaling connector (32).

A closure includes first and second closure portions. The first closure portion includes a top wall portion and annular skirt portion. An interior surface of the skirt portion includes an internal thread formation and further includes recessed portions. The second closure portion includes a tamper-evident band being detachably connected to the annular skirt portion by a frangible connection. The band includes a first portion and a second portion connected via a bending area. The second portion includes a tab section, first extension sections and second extension sections. The recessed portions are sized and shaped to receive a respective one of the first extension sections when the closure is in a closed position.
