Patent number: 5946964Abstract: A redraw die for a can body maker incorporates an undercut sidewall, a grooved face and a reduced radius at the intersection between the grooved face and the sidewall. The undercut side wall is positioned proximate to the grooved face so as to permit a cup positioned over the redraw die to flex into an ovoid shape without pinching or binding against the side of the redraw sleeve. These features help prevent the formation of wrinkles when the cup is drawn and ironed in the body maker.Type: GrantFiled: April 1, 1998Date of Patent: September 7, 1999Assignee: American National Can CompanyInventors: Walter Snyder, Gregory Giffhorn

Patent number: 5947287Abstract: A high temperature steam-sterilizable flexible pouch package includes a non-woven barrier web, a perforated plastic intermediate web, and an imperforate plastic upper web. Line heat seals bonding the webs form a cavity into which high temperature sterilizing steam may enter after passing through the barrier and intermediate webs. The line heat seal bonding the upper and intermediate webs is of the delamination failure type. An access opening is provided for insertion of an object to be sterilized into the cavity after which the access opening is sealed, enclosing the object in the cavity. After high temperature steam sterilizing, the package is opened by peeling apart the upper web from the intermediate web which causes a delamination failure of the line heat seal. Preferred materials enable vacuum cycle steam sterilization at a temperature of at least 270.degree.

Patent number: 5878549Abstract: An easy open tear control package, preferably a pouch, from a film of polymeric barrier material is disclosed. Methods and films for making of such packages are also disclosed. The easy open tear control feature arises from roughening portions of the outer or inner surface of the films, prior to fabricating into the package. The roughened portion is on one face or on each face of the package and is at least a full width of a seal when the film is made into the package. The roughened portion can extend the entire width of the package and can be of any desired length.Type: GrantFiled: September 29, 1997Date of Patent: March 9, 1999Assignee: American National Can CompanyInventors: Richard Littmann, Ulrich Weingartner, Thomas S.

Patent number: 5705111Abstract: Methods related to coextrusion of heat-sensitive polymer materials. The sensitive melt stream element (12) is encapsulated in a second polymeric melt stream element (16). Transport means (36) is preferably employed between the encapsulating means (20) and the die (42). A third melt stream element (68) is joined to one or both opposing surfaces (70) of the second melt stream element (16) between the encapsulating means (20) and the die (42). In the die (42) the encapsulated melt stream element (12) becomes an interior layer (46) between encapsulating layers (48A, 48B) derived from the second melt stream element (16). The third melt stream element (68) forms layers (72, 74) positioned outwardly of the encapsulating layers (48A, 48B). The positioning, on the interior of the extrudate, of edges (54) of layer (46) is adjusted independently of the combined thicknesses of a layer derived from the third melt stream element (68) and an adjacent layer (48).Type: GrantFiled: January 20, 1995Date of Patent: January 6, 1998Assignee: American National Can CompanyInventors: Robert John Blemberg, John P.
