摘要:
An apparatus and method of making and applying threaded twist-off neck finishes for metal containers is provided. More specifically, the present invention relations to apparatus and methods used to form metallic bottles with threaded necks adapted to receive selectively removable threaded closures. The threaded neck may be formed by interconnecting a threaded outsert to a metallic bottle. Alternatively, the threaded neck may be formed as an integral portion of the neck of the bottle.

The present disclosure provides methods and a necking apparatus to reduce a first diameter of an open end of a container body to a second diameter. The necking apparatus includes a necking die and a die guide. The die guide is selectively moveable relative to the necking die to guide the open end of the container body into engagement with the necking die. The die guide includes a flange that extends into a cylindrical bore of the die guide. The flange is configured to engage a shoulder of the container body when the die guide is in a first clamping position relative to the necking die. After engaging the container shoulder with the flange, the die guide moves toward the necking die into a second necking position such that the open end contacts the necking die and the first diameter of the open end is reduced to the second diameter.

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.
