Patent number: 6702538Abstract: A method of forming a can end comprises the step of forming a substantially circular metal blank having a periphery and a center panel. An annular recessed panel is subsequently formed in the blank. The recessed panel has a first depth in relation to a substantially annular portion of the blank contiguously formed with the recessed panel. The substantially annular portion of the blank is then coined while the recessed panel is re-formed to a second depth in relation to the substantially annular portion of the blank. The second depth is greater than the first depth. Forming the can end in this manner minimizes warpage of the can end, and thereby allows the can end to be formed from a relatively thin sheet of metal.Type: GrantFiled: February 15, 2000Date of Patent: March 9, 2004Assignee: Crown Cork & Seal Technologies CorporationInventors: Paul R.

Patent number: 6688832Abstract: A method of making an easy-open end for a container includes steps of forming first and second grooves in a panel of a can end blank, the grooves extending below the level of the panel to form inner and outer beads and forming a central bead in the panel between the first and second grooves so that the central bead extends above the panel. A score is then formed along the central bead by simultaneously forming the score and compressing the central bead, so that the depth of the score and the thickness of the central bead are both positively controlled. The inner and outer beads are then forced toward each other and then toward the panel, and the central bead is forced toward the panel. A pull-tab is then fixed to the end. This process permits the score residual to be controlled to a greater tolerance than the conventional processes, and is also more material efficient.Type: GrantFiled: April 12, 2000Date of Patent: February 10, 2004Assignee: Crown Cork & Seal Technologies CorporationInventor: Edgar Zysset

Patent number: 6685417Abstract: An easy open safety end having a central portion and a rim portion separated by a score line. A tab applies a force to the end adjacent the score line so as to shear the score line at opening. A circumferentially extending fold is formed in either the central portion or the rim portion, or both, to protect the user from being cut by the sharp edge the results upon shearing the score line. A first circumferential portion of the fold is tight, whereas a second portion, which is preferably proximate the tab is loose. The fold is displaced below a portion of the end adjacent the score line by a circumferentially extending gap. In the tight portion of the fold, the width of the gap is less than the thickness of the end, and preferably less than one half the thickness, whereas in the loose portion of the fold, the width of the gap is greater than the thickness of the end, and is preferably at least twice the thickness of the end.Type: GrantFiled: April 26, 2002Date of Patent: February 3, 2004Assignee: Crown Cork & Seal Technologies CorporationInventors: Paul R.

Patent number: 6659308Abstract: A dispensing closure (18) for a container (10) of liquid product (70, 72) which is sealed by a piercable diaphragm (16). The closure includes a piercing member 924) which is moveable through a predetermined distance towards the container and which has a cutting edge arranged to pierce the diaphragm to form a dispensing aperture. At the end of its movement towards the interior of the container, the piercing member is arranged to plug the dispensing aperture against escape of the product when the container is inverted prior to dispensing. The closure is particularly useful for liquid products which tend to separate into a lighter (70) and heavier (72) fraction during storage. The closure prevents dripping of the lighter fraction when the container is inverted and allows the heavier fraction to displace the lighter fraction adjacent to the dispensing aperture before dispensing occurs.Type: GrantFiled: May 20, 2002Date of Patent: December 9, 2003Assignee: Crown Cork & Seal Technologies CorporationInventors: Maria Louise Kelder, Christopher Paul Ramsey
