A drawn and ironed container (C) that includes a cylindrical side wall, a smoothly-tapered neck (134) with an open end and an integral bottom wall (137) at the opposite end has a plurality of inwardly-deformed panel segments (130) located in the side wall between adjacent arcuate segments (132) with the panel defining generally chordal bottom walls for the panel segments. The container is formed using a multi-station processing apparatus that consists of a plurality of identical stations (30) located around the periphery of a rotating turret (26). Each station includes a support mandrel (50), a container loading means (52, 53) and an impression mandrel (54), with the impression mandrel being pivoted into and out of pressure engagement with the support mandrel to deform the side wall of the container. The support mandrel has a cylindrical peripheral surface (102) that conforms to the inner diameter of the container side wall and has circumferentially-spaced, axially-extending pockets (104. The pockets have sharp opposite edges (108a) that cooperate with the impression mandrel to produce the panel segments in the side wall.
A method of processing a drawn and ironed open-ended container having a dome-shaped bottom wall merging with a cylindrical side wall through a generally U-shaped annular support member including a rotating turret (26) having a plurality of peripheral stations (30) with each station having a rotation rigid mandrel (50) and loading means (52, 53) for loading a container onto said mandrel, said mandrel having a peripheral surface (102) conforming generally to an inner diameter of said container and having spaced pockets (104) formed therein, each station including an impression mandrel (54) associated therewith, the steps of introducing containers to said loading means at each station and introducing said container onto said rigid mandrel, moving said impression mandrel into pressure engagement with said rigid mandrel to grip said container therebetween, driving said rigid mandrels and said impression mandrels to deform said side walls of said containers into said pockets and providing a support (80, 82) between an adjacent pair of stations with an adjacent pair of impression mandrels supported thereon, and pivoting said support to simultaneously produce pressure engagement between said adjacent pair of impression mandrels and an adjacent pair of rigid mandrels.
Apparatus for processing drawn and ironed containers having a cylindrical side wall integral with a bottom wall that includes a inwardly-domed center panel surrounded by a U-shaped annular support member comprising a turret (26) rotated about a fixed support (24) and having a plurality of peripheral processing stations (30);
A method of continuously reshaping open-ended containers having a side wall upstanding from a bottom, said method utilizing a rotating turret (26) having a plurality of stations (30) with each station having a rotating support mandrel (50), and means (52, 53) for loading a container onto said support mandrel, said support mandrel having a peripheral surface (102) adapted to engage an inner side wall surface of said container and having a design (104) formed thereon, each station including an impression mandrel (54) associated therewith, said method comprising:
An apparatus for continuous reshaping of side walls of containers, comprising a turret (26) rotatable about a fixed support (24) and having a plurality of reshaping stations (30) thereon, each reshaping station including a support mandrel (50), an impression mandrel (54) movable into and outer of engagement with said support mandrel, loading means (52, 53) for introducing a container onto said support mandrel, said support mandrel including a peripheral surface (102) adapted to engage an inner side wall surface of said container, and having a design (104) formed thereon, and means to automatically adjust the synchronous rotation of said support and impression mandrel, wherein said automatic adjustment is achieved by a frictional drive.
A continuous method of reshaping a plurality of containers, each of said containers having a side wall, said method comprising:
Apparatus for continuously processing containers, comprising:
