A closing cap for closing a container comprises a cylindrical threaded part having an open edge and an internal screw thread, which can interact with an external screw thread of the container neck. A tamper-proof strip is configured to be retained on an annular protrusion formed on the container neck. A retaining strip has a first and a second end and a first and a second edge. The first end is fixedly connected to the open edge of the threaded part, and the second end is fixedly connected to the tamper-proof strip. The first edge is detachably connected to the open edge of the threaded part by a predetermined breaking element, and the second edge is detachably connected to the tamper-proof strip by a second predetermined breaking element. The first predetermined breaking element and the second predetermined breaking element have different tensile strengths or tear strengths.

A canister includes a closure configured to mount on a container to close an open mouth into a product storage region formed in the container. The closure includes a lid and a lid retainer coupled to the lid. The lid retainer is configured to mate with an external thread on the container to retain the closure in a mounted position on the container.

A closure can close an outlet of a vessel. The vessel outlet can comprise a tubular cavity with an interior surface. The closure can comprise a male portion comprising a distal undersized portion, a proximal oversized portion, and a taper between the undersized and oversized portion. The male portion can be inserted in the vessel outlet, undersized portion first. Interference between the inner diameter of the vessel outlet and the outer diameter of male portion can occur when the male portion is sufficiently inserted. The interference can cause the undersized portion to flare out and engage the interior surface of the tubular cavity, thereby providing a seal.

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 closure for a container includes a top panel, a skirt depending from the top panel and extending circumferentially about a central axis, a tamper-evident band attached to the skirt, and at least one thread extending from an interior surface of the skirt. The skirt extends from a first end attached to the top panel to a second end opposite the first end. The skirt is tapered radially outward from the first end to the second end such that a diameter of the skirt at the second end is greater than the diameter of the skirt at the first end.

A closure having a liner is provided. The liner forms one or more venting recesses that facilitate relieving pressure from a container to which the closure is affixed. In embodiments the liner extends from an outer surface of an annular wall through an outer disc of the liner.

The presently-disclosed subject matter includes valve covers. The valve covers can protect valves from exposure as well as from tampering. In some embodiments the valve cover comprises a cap that includes a top end and a side wall that is substantially cylindrical. Embodiments of valve covers also include a plug on an interior side of the top end of the cap that projects toward the opening of the cap. When the valve cover is installed, the plug can extend beyond an opening of the valve.
