Abstract:
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.
