A closure having an angled plug seal extending from a lower surface of the top panel of the closure is provided. The outer surface of the plug is formed having an upper portion, a middle portion, a transition section and a lower portion. The upper portion, middle portion and lower portion each extend along planes that extend at differing angles relative to the vertical axis about which the closure is centered. The configuration of the outer surface of the plug allows a single closure to interchangeably be used to fluidly seal containers having any number of different container neck finish configurations.

Methods and apparatus for sealing a threaded container are provided. More specifically, the present invention relates to a ROPP closure with a novel pilfer band that may be used to seal a bottle shaped container without pressing directly against the bottle or deforming the bottle. The bottle includes an annular ring that is novel. Optionally, the annular ring can be formed without die necking or expanding the bottle neck. At least one protrusion which extends inwardly at least partially into the bottle annular ring is formed on the ROPP closure after the ROPP closure is positioned on the bottle neck. In one embodiment, the ROPP closure includes one inwardly oriented protrusion which extends around the circumference of the ROPP closure. The protrusion can be formed by a roller. Optionally, the protrusion has a substantially uniform depth. In another embodiment, the ROPP closure includes a plurality of individuals studs which each extend at least partially into the bottle annular ring. The individual studs can be formed by one or more of a punch, a stud roller, a studded rail, a collet actuated tool, and a cam actuated tool of embodiments of the present invention.

An apparatus and methods of sealing a metallic container are provided. More specifically, the present invention relates to capping apparatus and methods that reduce the amount of force applied to a metallic bottle to seal the metallic bottle with a ROPP closure. The capping apparatus may include more thread rollers than known capping apparatus. Optionally, the thread rollers may use more forming passes to form threads on the ROPP closure. The capping apparatus may also rotate one or more of the ROPP closure and the metallic container in a closing direction before the metallic container is discharged. In one embodiment, the thread rollers form the closure threads before or after a pilfer roller applies a sideload to the ROPP closure.

Disclosed is a metal container including a neck, wherein a screw thread and a ring collar are provided. The screw thread:includes a top radius between 0.85 and 1.2 mm and a bottom radius between 0.5 and 0.7 mm;the lower flank of the ring collar, which diverges from the top flank in the direction of the longitudinal axis, defines an angle of between 20 and 30 relative to a plane perpendicular to the longitudinal axis;the outer rim of the bottom flank of the ring collar has a radius between 0.7 and 0.9 mm, andthe inner rim of the lower flank of the ring collar is provided at a distance of between 13 and 15 mm relative to the free rim of the neck.

A method of operating a closing station includes decoupling a first closing element from a working position of the closing station and moving it away from the working position, bringing a second closing element into the working position, and coupling it into the container transport path at the working position.

A capping head for a capping machine including: a locking unit having a connecting portion and a capsule-pressing locking portion, wherein the connecting portion can be reversibly translated relative to the capsule-pressing locking portion between proximal and distal positions; a capping unit for capping a containment body; a drive unit to reversibly move the capping unit between operating and rest configurations; a transmission, acting between the connecting portion and the drive unit, to determine a rotation of the drive unit during a movement of the connecting portion between the proximal and distal positions. The capping unit includes rolling elements which can be activated on the side wall of the capsule to shape it to match a threaded portion of the containment body and is rotationally integral with the drive unit to perform a capping of the containment body activating the rolling elements for deforming the side wall of the capsule.
