Abstract: A drawn and wall ironed beverage can body, method for forming same, and a sealed and filled can, include a through-hole or aperture in the base. A grommet for charging a propellant in can is located in the aperture. The aperture has a burr that is located on the inboard side of the rim of the aperture. A method of forming a valve in the drawn and ironed beverage can body includes positioning a first tool in an interior of the can body, contacting an exterior surface of the base with a second tool such that the first and second tools are aligned, forming the aperture in the base, and inserting the grommet into the aperture.

Abstract: A beverage can end includes a filling port in the end itself. An activating gas that interacts with the beverage may be charged through the filling port. If the end has a vent opening, such as sometimes used in a recloseable end, the vent opening may be used for charging the activating gas.

Abstract: Redraw tooling includes a punch tool, a punch ring that is retractable relative to the punch tool, a punch sleeve, and a spring or resilient material that urges the punch ring forward. Retracting the punch ring provides support for the redraw chine to diminish wrinkling.

Abstract: A system for creating marked can tabs may include an isolation mechanism located in the path of the tab material strip between a tab material dereeler and a tab forming press and a system suitable for marking the tab material strip. The isolation mechanism may be configured to convert discontinuous motion of the tab material strip proximate the tab forming press into continuous motion of the tab material strip at the dereeler. The system may be suitable for marking the tab material strip. The marking system may be located between the dereeler and the isolation mechanism such that the laser system acts on the tab material strip while it is moving at a relatively constant speed.

Abstract: A chuck-knockout assembly for seaming a can end onto a can body to form a seamed container is disclosed. The chuck-knockout assembly may include an upper chuck body and a lower chuck body. The upper chuck body may include a first drive surface and may be rotatably coupled to a seaming machine frame. The lower chuck body may include a second drive surface and may be longitudinally moveable relative to the upper chuck body. The second drive surface may be configured to engage a periphery of the can end during seaming and disengagement of the container.

Abstract: A method and apparatus for reforming the base profile of a can by using the difference in rotational speed of concentric shafts (A, B) to move a roller (5) radially into contact with the can base. A cam (10) is fixed to one (B) of the shafts and a pair of cam followers (12, 14) is mounted on a support block (6) which is connected to the other shaft (A) via linear bearings (7, 8). The support block also carries the reform roller and causes it to rotate around the can base.

Abstract: A method and apparatus for reforming the base of a container such as a can having a domed base. The apparatus comprises independent assemblies for rotating the can and for reforming the base profile. The base reforming assembly uses a torque shaft to twist an eccentric and actuate radial movement of a roll into contact with the can base. A stop prevents movement of this roll beyond a predetermined amount, thereby maintaining consistency of profile depth. By minimizing moving parts of the tooling, wear is limited to that which may arise from the stop alone.

Abstract: A method of manufacturing a metallic can body that is shaped distinctively in order to enhance its visual presentation to consumers includes, in one embodiment, steps of providing a can body blank that has a sidewall that is of a substantially constant diameter; providing a mold unit that has at least one mold wall that defines a mold cavity conforming a desired final shape of the can body; positioning the can body blank within the mold cavity; and supplying a pressurized fluid into the mold cavity so that the can body blank is forced by pressure against the mold wall, causing the can body blank to assume the desired final shape of the can body. Axial compression is preferably applied to the can body blank in order to reduce internal stresses during molding of the container.

Abstract: An annular device (10) particularly for use as a spacer between dies (200) in a drawing and wall ironing process, the device including an outer delivery channel (30) which is linked to an inner delivery channel (40) by angled slots (50), so that liquid passing from the outer to the inner channel merges in the inner channel to form a vortex of fluid. The device also includes a lip (42) on the wall of the inner channel adjacent to the bore of the device, which serves as directing means to force the merged vortex of liquid out of the spacer in a longitudinal manner for cooling, lubricating and washing adjacent members.
