Abstract: A resealable can end is provided including a neck member and hat member which can be sealed onto and removed from the neck member of the end, and is capable of containing product under pressure if desired. This end can be added, as by a conventional seam, to a metal container body to obtain resealing containment of partial contents retained in the container, and to provide an improved mouth construction (or pour opening) for better pouring and for comfortable direct drinking from the container. Also disclosed are improved methods of and apparatus for making such a resealable hat and-neck type-of container end.

Abstract: The disclosure relates to a novel shell such as used in the manufacture of can ends, and to a method and tools for making such a shell. A non-circular blank having rounded corners is cut from thin metal. The blank is oblong in a direction transverse to the grain of the metal. A first set of tools separates the blanks and forms a substantially flat central panel and an upward-extending chuck wall about the edge of the panel to produce a partially formed shell. The junction area between the panel and the chuck wall has a relatively large radius of curvature at this time. A second set of tools forms in the blank a lip extending outward from the upper end of the chuck wall and generally parallel to the panel; then the panel and the chuck wall are separately gripped, followed by relative movement between the panel and the chuck wall while wrapping the junction area around a forming punch to form a panel wall in the junction area extending upward from the inner part of the chuck wall.

Abstract: Methods and apparatus are disclosed for fabricating from ductile sheet metal a can body with integral side and bottom walls. A rounded non-circular blank is formed from the sheet metal, the blank having a greater width across the grain of the metal than along such grain. The blank is formed into a cup-shaped receptacle having a bottom and an upstanding wall of not less than the desired internal size of the can body. The wall has a length substantially less than the desired depth of the can body and is substantially thicker than the thickness desired in the finished can body. The wall is then thinned to the desired thickness so as to lengthen the wall to at least the desired depth of the can body.

Abstract: An apparatus for transferring a relatively flat object from a first station to a second station includes a support for the object at the first station, a substantially closed housing, and a piston disposed therein for sliding movement from a normal position to an activated position. An actuator extends through the housing and is integrally formed with the piston for sliding movement thereby. Compressed air is selectively directed into the housing for movement of the piston to the activated position, whereby the actuator strikes a blow edgewise of the object for propelling it toward the second station along a predetermined path. A pair of fingers disposed at the second station define therebetween a portion of the path along which an incoming object enters the second station. Each finger includes a path wall having an end surface extending generally inwardly from the finger for blocking the object path for halting object movement.

Abstract: The disclosure relates to method and tools for making shells used in the manufacture of can ends. A first set of tools makes blank pre-forms having a substantially flat central panel and an upward-extending chuckwall about the edge of the panel. The junction area between the panel and the chuckwall has a relatively large radius of curvature at this time. A second set of tools forms on the blanks a lip extending outward from the upper end of the chuckwall and generally parallel to said panel; then the panel and the chuckwall are separately gripped, followed by relative movement between the panel and the chuckwall while wrapping the junction area around a forming punch to form a panel wall in the junction area extending upward from the inner part of the chuckwall. Then the lip is formed into a curl edge section which ends in an inner curl diameter that is round and concentric with the chuckwall.

Abstract: A method and apparatus for forming shells for use as can ends is disclosed. A sheet of thin metal is supplied to a first station within a ram press, at which a generally circular blank is separated from the sheet and partially formed into the shell. The partially formed shell is transferred from the first station along a predetermined path to a second station within the same press by striking a blow edgewise of the shell and thereby directing it edgewise to the second station. The shell is captured and located at the second station, whereupon the shell is further formed to make the completed shell.
