The transition wall has a folded portion extending outwardly relative to the longitudinal axis.
Description
- This application is a continuation of co-pending U.S. application Ser. No. 09/931,497, which was filed on Aug. 16, 2001, and is now U.S. Pat. No. X,XXX,XXX.
- The present invention relates to end closures for two-piece beer and beverage metal containers having a non-detachable operating panel. More specifically, the present invention relates to a method of reducing the volume of metal in an end closure.
- Common easy open end closures for beer and beverage containers have a central panel that has a frangible panel (sometimes called a “tear panel,” “opening panel,” or “pour panel”) defined by a score formed on the outer surface, the “consumer side,” of the end closure. Popular “ecology” can ends are designed to provide a way of opening the end by fracturing the scored metal of the panel, while not allowing separation of any parts of the end. For example, the most common such beverage container end has a tear panel that is retained to the end by a non-scored hinge region joining the tear panel to the reminder of the end, with a rivet to attach a leverage tab provided for opening the tear panel. This type of container end, typically called a “stay-on-tab” (“SOT”) end has a tear panel that is defined by an incomplete circular-shaped score, with the non-scored segment serving as the retaining fragment of metal at the hinge-line of the displacement of the tear panel.
- The container is typically a drawn and ironed metal can, usually constructed from a thin sheet of aluminum or steel. End closures for such containers are also typically constructed from a cut-edge of thin sheet of aluminum or steel, formed into a blank end, and manufactured into a finished end by a process often referred to as end conversion. These ends are formed in the process of first forming a cut-edge of thin metal, forming a blank end from the cut-edge, and converting the blank into an end closure which may be seamed onto a container. Although not presently a popular alternative, such containers and/or ends may be constructed of plastic material, with similar construction of non-detachable parts provided for openability.
- One goal of the can end manufacturers is to provide a buckle resistant end. U.S. Pat. No. 3,525,455 (the '455 patent) describes a method aimed at improving the buckle strength of a can end having a seaming curl, a chuckwall, and a countersink along the peripheral edge of a central panel. The method includes forming a fold along at least substantially the entire length of the chuckwall. The fold has a vertical length that is approximately the same length as the seaming curl, and a thickness that is approximately equal to the length of the remaining chuckwall wherein the fold is pressed against the interior sidewall of the container when the end is seamed to the container's open end.
- Another goal of the manufacturers of can ends is to reduce the amount of metal in the blank end which is provided to form the can end while at the same time maintaining the strength of the end. One method aimed at achieving this goal is described in U.S. Pat. No. 6,065,634 (the '634 patent). The '634 patent is directed to a can end member having a seaming curl, a chuckwall extending downwardly from the seaming curl to a countersink which is joined to a central panel of the can end. The method of the '634 patent reduces the amount of metal by reducing the cut edge of the blank. This is accomplished by increasing the chuckwall angle from approximately 11-13 degrees to an angle of 43 degrees.
- The method of the '634 patent may decrease the diameter of the central panel. This could reduce area on the central panel that is needed for written instructions, such as opening instructions or recycling information. It may also restrict the size of the tear panel. Furthermore, because the angle of the chuckwall is increased, the space between the perimeter of the can end and the tear panel is increased. This could cause spillage during pouring and/or drinking.
- The method of the '634 patent also produces a countersink. The '455 patent shares this aspect. The countersink is provided in the can end to improve strength. However, because the countersink is a narrow circumferential recess, dirt will often collect within the countersink. Additionally, the dirt is often difficult to rinse away due to the geometry of the countersink.
- One object of the present invention is to provide an easy open can end member comprising a central panel, a seaming curl, a circumferential chuckwall, and a transition wall. The central panel is centered about a longitudinal axis and has a substantially planar peripheral edge. The seaming curl defines an outer perimeter of the end member. The chuckwall extends downwardly from the seaming curl. The transition wall connects the chuckwall with the substantially planar peripheral edge of the central panel. The transition wall comprises a folded portion extending outwardly relative to the longitudinal axis.
- Another object of the present invention is to provide an easy open can end member comprising a central panel, a seaming curl, a circumferential chuckwall, and a transition wall. The central panel is centered about a longitudinal axis and has a substantially planar peripheral edge, a public side and a product side. The seaming curl defines an outer perimeter of the end member. The chuckwall extends downwardly from the seaming curl. The transition wall connects the chuckwall with the peripheral edge of the central panel and comprises a fold including a concave annular portion engaging the peripheral edge of the central panel.
- Another object of the present invention is to provide an easy open can end member comprising a central panel, a seaming curl, a circumferential chuckwall, and a transition wall. The central panel is centered about a longitudinal axis. The seaming curl defines an outer perimeter of the end member. The circumferential chuckwall extends downwardly from the seaming curl at an obtuse angle. The transition wall connects the chuckwall with the central panel, and the transition wall comprises a fold having a portion extending outwardly relative to the longitudinal axis and upwardly relative to the central panel wherein the fold has a thickness which is substantially less than a length of the chuckwall.
- Another object of the present invention is to provide an easy open can end member comprising a central panel, a seaming curl, a circumferential chuckwall, and a transition wall.

The seaming curl defines an outer perimeter of the end member and is adapted for connecting the end member to a container body. The chuckwall extends downwardly from the seaming curl. The transition wall connects the chuckwall with the peripheral edge of the central panel, and comprises a fold extending outwardly relative to the longitudinal axis and upwardly relative to the central panel. The transition wall has a vertical length that is less than a length of the seaming curl.

- While this invention is susceptible of embodiment in many different forms, there are shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
- The container end of the present invention is a stay-on-
tab end member 10 with improved physical properties including strength. Essentially, the present invention provides alightweight end member 10 which embodies the physical characteristics and properties required in the beverage container market, as explained below. - Referring to FIG. 1, the
end member 10 for a container (not shown) has a seamingcurl 12, achuckwall 14, atransition wall 16, andcentral panel wall 18. The container is typically a drawn and ironed metal can such as the common beer and beverage containers, usually constructed from a thin sheet of aluminum or steel that is delivered from a large roll called coil stock of roll stock. End closures for such containers are also typically constructed from a cut edge of thin sheet of aluminum or steel delivered from coil stock, formed into blank end, and manufactured into a finished end by a process often referred to as end conversion. In the embodiment shown in the Figures, theend member 10 is joined to a container by a seamingcurl 12 which is joined to a mating curl of the container. The seamingcurl 12 of theend closure 10 is integral with thechuckwall 14 which is joined to an outerperipheral edge portion 20 of thecentral panel 18 by thetransition wall 16. This type of means for joining theend member 10 to a container is presently the typical means for joining used in the industry, and the structure described above is formed in the process of forming the blank end from a cut edge of metal sheet, prior to the end conversion process. However, other means for joining theend member 10 to a container may be employed with the present invention. - The
central panel 18 has a displaceable tear panel 22 defined by a curvilinear frangible score 24 and a non-frangible hinge segment 26. The hinge segment 26 is defined by a generally straight line between afirst end 28 and asecond end 30 of the frangible score 24. The tear panel 22 of thecentral panel 18 may be opened, that is the frangible score 24 may be severed and the tear panel 22 displaced at an angular orientation relative to the remaining portion of thecentral panel 18, while the tear panel 22 remains hingedly connected to thecentral panel 18 through the hinge segment 26. In this opening operation, the tear panel 22 is displaced at an angular deflection, as it is opened by being displaced away from the plane of thepanel 18. - The frangible score24 is preferably a generally V-shaped groove formed into the
public side 32 of thecentral panel 18. A residual is formed between the V-shaped groove and theproduct side 34 of theend member 10. - The
end member 10 has atab 36 secured to thecentral panel 18 adjacent the tear panel 22 by arivet 38. Therivet 38 is formed in the typical manner. - During opening of the
end member 10 by the user, the user lifts alift end 40 of thetab 36 to displace anose portion 42 downward against the tear panel 22. The force of thenose portion 42 against the tear panel 22 causes the score 24 to fracture. As thetab 36 displacement is continued, the fracture of the score 24 propagates around the tear panel 22, preferably in progression from thefirst end 28 of the score 24 toward thesecond end 30 of the score 24. - Now referring to FIG. 2, the
central panel 18 is centered about alongitudinal axis 50. The seamingcurl 12 defines an outer perimeter of theend member 10 and is integral with thechuckwall 14. Thechuckwall 14 extends downwardly from the seamingcurl 12 at an obtuse angle. A chuckwall angle α measured from a planar or substantially planarperipheral edge portion 52 of thecentral panel 18 is generally between 10 and 70 degrees, more preferably between 15 and 45 degrees, and most preferably 19 to 27 degrees, or any range or combination of ranges therein. Thechuckwall 14 may be provided with a radius of curvature as shown in the drawings to improve performance within the forming tools used to form theend member 10. The radius of curvature helps prevent buckling within the tools as force is applied to theunfinished end member 10. - The
transition wall 16 is integral with the chuckwall 14 and connects thechuckwall 14 the to theperipheral edge portion 52 of thecentral panel 18. Theend member 10 differs from contemporary beverage can end members that typically include a countersink formed in the outer peripheral edge of the central panel. The planarperipheral edge portion 52 allows the tear panel 24 to be place closer to the outer perimeter of theend member 10. It also provides additionalcentral panel 18 area for printing and/or a larger tear panel opening. - The
transition wall 16 includes afold 54 extending outwardly relative to thelongitudinal axis 50. The drawings show thefold 54 formed along an exterior portion of thechuckwall 14; however, it should be understood that thefold 54transition wall 16 can be located in other locations such as along theproduct side 34 of thecentral panel 18. - The
fold 54 has afirst leg 56 connecting thechuckwall 14 to an annular concave bend orportion 58. The annularconcave portion 58 includes and apex 60 which engages the outerperipheral edge 52 of thecentral panel 18. This contact between the apex 60 and the outerperipheral edge 52 helps to prevent dirt from accumulating along theperipheral edge 52 of thecentral panel 18. It also allows thecentral panel 18 to be easily cleaned when dirt or other residue is present on thecentral panel 18. - A
second leg 62 extends upwardly from the annularconcave portion 58 to an annular convex bend orportion 64. Thesecond leg 62 can be vertical, substantially vertical, or up to ±25 degrees to thelongitudinal axis 50 and can be pressed against an outer portion of thefirst leg 56. - The annular
convex portion 64 includes an apex 66 which defines a vertical extent of thefold 54. A length of thefold 54 is substantially less than a length of the seamingcurl 12. In combination with, inter alia, theangled chuckwall 14, thisfold 54 structure and length allows the buckling strength of theend member 10 to be meet customer requirements while decreasing the size of the cut edge blank and maintaining the diameter of the finished end. In other words, a smaller cut edge blank can be provided to produce the same sized diameter end member as a larger cut edge blank formed in the conventional manner with a countersink. - A
third leg 68 extends downwardly from the annularconvex portion 64 to athird bend 70 which joins thetransition wall 16 to the outerperipheral edge 52 of thecentral panel 18. Thethird bend 70 has a radius of curvature which is suitable for connecting thethird leg 68 to the planar outer peripheral edge of thecentral panel 18. - The
third leg 68 can be pressed against an outer portion of thesecond leg 62. This gives the fold 54 a transverse thickness which is substantially equal to three times the thickness of the thickness of thechuckwall 14, and is the transverse thickness of thefold 54 is substantially less than the length of thechuckwall 14. Again, this structure results in a metal savings by allowing the cut edge blank to be smaller than conventional cut edge blanks used to make the same diameter end member. For example, the average diameter of a cut edge blank used to form a standard 202 can end is approximately 2.84 inches while the average diameter of a cut edge blank used to form a 202 can end of the present invention is approximately 2.70 inches. - FIGS. 3-8 and FIGS. 9-13, illustrate one method for forming an
end member 10 of the present invention. FIGS. 3-8 show the progression of theend member 10 from a shell to thefinished end 10 without the tooling. FIGS. 9-13 show the tooling contemplated for forming theend member 10. The method shows thefold 54 formed from a lower segment of thechuckwall 14 called referred to as thetransition wall 16 herein. However, it should be understood that thetransition wall 16 can be formed from a portion of theperipheral edge 52 of thecentral panel 18 without departing from the spirit of the invention. - Referring to FIGS. 3 and 9, the method includes the step of providing an
end shell 80. Theend shell 80 includes ahinge point 82 formed at the junction between the chuckwall 14 and thetransition wall 16. In FIG. 4, thehinge point 82 is a coined portion on an interior of theend shell 80. In FIG. 9, thehinge point 82 is a coin on the exterior of theend shell 80. Thehinge point 82 may also be provided along theperipheral edge 52 ofcentral panel 18. Thehinge point 82 is provided to initiate bending at a predetermined point along thechuckwall 14/transition wall 16. In this example, thehinge point 82 defines the boundary between the chuckwall 14 and thetransition wall 16. - The
end shell 80 also includes anangled portion 84 along theperipheral edge 52 of thecentral panel 18. This angled portion is formed to promote stacking of theend shells 80 as they are transported from a shell press to a conversion press. Theangled portion 84 also promotes metal flow outwardly relative to thelongitudinal axis 50 to promote formation of thefold 54 in the conversion press. - FIGS. 4-8 and10-13 show a process of converting the
end shell 80 to thefinished end member 10 in a four stage operation carried out in a conversion press. In the first stage (FIGS. 4, 5 and 10), relative movement between the tooling members causes an outward bulge (the beginning of the annular convex portion 64) to form in thetransition wall 16. The bending of thetransition wall 16 is initiated at the hinge point 82 (the beginning of the annular concave portion 58). At the same time, theangled portion 84 of theperipheral edge 52 is flattened to form theperipheral edge 52 into a planar structure. The relative movement of the tooling also causes thehinge point 82 to move towards the flattenedperipheral edge 52 of thecentral panel 18. - FIGS. 6 and 11 illustrate the second stage of the conversion press. In the second stage, relative movement by the tooling forces the
hinge point 82 towards theperipheral edge portion 52. The annularconvex portion 64 is fully formed and extends outwardly substantially perpendicular to thelongitudinal axis 50. A portion of thehinge point 82 is engaging or very nearly engaging theperipheral edge 52 of thecentral panel 18. - FIGS. 7 and 12 illustrate the third stage of the conversion press. In the third stage, relative movement by the tooling forces the
fold 54 upwardly relative to thecentral panel 18. This forms thethird bend 70 and shortens a radius of curvature of the annularconcave portion 58. - FIGS. 8 and 13 illustrate the fourth stage of the conversion press. In the fourth stage, relative movement by the tooling forces the
fold 54 farther upwardly relative to thecentral panel 18 until thefold 54 is substantially vertical, parallel with thelongitudinal axis 50. The annularconcave portion 58 is fully formed and is in engagement or very nearly in engagement with theperipheral edge portion 52. - FIG. 14 illustrates an alternative embodiment of the can end10 of the present invention. In this embodiment, the
fold 54 extends inwardly relative to thelongitudinal axis 50. The annularconcave portion 58 does not contact theperipheral edge 52. - FIG. 15 illustrates yet another embodiment of the can end10 of the present invention. In this embodiment, the
chuckwall 14 includes an outwardly extendingstep 90 for increased strength. Thestep 90 bends outwardly against the annularconvex portion 64. In this embodiment, the outer portion of the step engages vertical extent of the annularconvex portion 64. - While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the broader aspects of the invention. Also, it is intended that broad claims not specifying details of a particular embodiment disclosed herein as the best mode contemplated for carrying out the invention should not be limited to such details.
