Apparatus and methods of forming and applying roll-on pilfer proof closures on the threaded neck of metal containers
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.
CHILDPROOF TAMPER EVIDENT CLOSURE ASSEMBLY
Systems, methods, and apparatuses for sealing bottles with a Roll-on Pilfer Proof (ROPP) closure and a childproof overcap are provided. More specifically, the present disclosure relates to an overcap that can be placed onto or formed onto the ROPP closure. The overcap has a retainer that secures the overcap to the ROPP closure and allows the overcap to move relative to the ROPP closure in a longitudinal axis. The overcap moves between a first position or mode of operation where the overcap can rotate about the ROPP closure and a second position or mode of operation where the overcap engages the ROPP closure to transmit a twisting or torque force to the ROPP closure and open the bottle.
METALLIC CONTAINER WITH A THREADED CLOSURE
The present invention relates generally to a container that may be sealed and reclosed with a threaded closure. More specifically, the present invention relates to methods of manufacturing a metallic container having an opening with inwardly facing threads. The threads are formed on the metallic container by pressing a neck portion of the metallic container against closure threads of a threaded closure which is inserted at least partially into the opening. The container threads may optionally be formed while the threaded closure is in tension. In this manner, after the container threads are formed, the closure threads can apply a force to the container threads such that the threaded closure is in tension. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads. Novel apparatus and methods of sealing metallic containers and forming threads on the metallic containers are also disclosed.
METHODS OF CAPPING METALLIC BOTTLES
Methods of sealing a metallic container are provided. More specifically, the present invention relates to methods that reduce the amount of force applied to a metallic bottle to seal the metallic bottle with a ROPP closure. The methods include use of a capping apparatus that 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.

Method for operating a closing station and closing station
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.

Metal container comprising a neck capable of receiving a screw cap-type sealing element
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.
