Abstract
Abstract A tag ring element having a neck portion and a base portion and bordering the openings in container walls and methods and apparatus for at least partially forming the same during the application of the closure elements to the container walls, including means for automatically feeding and positioning blanks for such tag ring elements in position for securement during the securing of closure elements about said container wall openings. The tag ring elements may be preformed to varying degrees depending upon the means for holding them in the dies and may be of varying thicknesses, depending on whether they serve as the sole securing neck for securing closure flanges to container wall openings, whether they reinforce lightweight necks formed in the container wall, or whether they principally serve to provide eyelets for the attachment of various elements thereto. In a particular instance, the tag ring element flat blanks are fed into the dies which perforate container walls, draw necks up from the same form and secure the tag ring elements thereto, and secure closure flanges within such necks in one stroke of a press. Particular feeding and holding means for the tag ring elements for the automatic application of the same to container wall necks simultaneously with the application of the closure flange to the opening being formed, is provided in the instance of single stroke application of closures to the container walls.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
The method of simultaneously securing a closure flange and a tag ring element to a container wall in a single punch press operation, comprising the steps of supporting a closure flange including a cylindrical nEck having an upper unthreaded portion and a lower internally threaded portion surrounded by a polygonal base, positioning an annular tag ring element in vertically spaced concentric relationship above said closure flange, placing an imperforate container wall between said closure flange and said tag ring element, vertically displacing said tag ring element and said closure flange toward each other, perforating a concentric opening in said container wall and permanently securing said closure flange and said tag ring element about said container wall opening.
Claim 2
Independent Claim
117 words
The method of simultaneously securing a closure flange and a tag ring element to a container wall in a single punch press operation, comprising the steps of supporting a closure flange including a cylindrical nEck having an upper unthreaded portion and a lower internally threaded portion surrounded by a polygonal base, positioning an annular tag ring element in vertically spaced concentric relationship above said closure flange, placing an imperforate container wall between said closure flange and said tag ring element, vertically displacing said tag ring element and said closure flange toward each other, perforating a concentric opening in said container wall and permanently securing said closure flange and said tag ring element about said container wall opening.
Claim 3
Dependent Claim
23 words
The method as in claim 1 and forming said tag ring element with an upstanding neck from a flat blank during said securing.
Claim 4
Dependent Claim
19 words
The method as in claim 1 and deforming said container wall and said tag ring element during said securing.
Claim 5
Independent Claim
96 words
The method of simultaneously securing a closure flange and a tag ring element to a container wall in a single punch press operation comprising the steps of positioning an internally threaded closure flange in a lower die sub-assembly, retaining an annular tag ring element on an upper die sub-assembly operatively positioned above said lower die sub-assembly, positioning a container wall between said upper and lower die sub-assemblies, closing said upper die sub-assembly on said lower die sub-assembly and permanently securing said closure flange and said tag ring element about an opening formed in said container wall.
Claim 6
Independent Claim
96 words
The method of simultaneously securing a closure flange and a tag ring element to a container wall in a single punch press operation comprising the steps of positioning an internally threaded closure flange in a lower die sub-assembly, retaining an annular tag ring element on an upper die sub-assembly operatively positioned above said lower die sub-assembly, positioning a container wall between said upper and lower die sub-assemblies, closing said upper die sub-assembly on said lower die sub-assembly and permanently securing said closure flange and said tag ring element about an opening formed in said container wall.
Claim 7
Dependent Claim
23 words
The method as in claim 4 and forming said tag ring element with an upstanding neck from a flat blank during said securing.
Claim 8
Dependent Claim
19 words
The method as in claim 4 and deforming said container wall and said tag ring element during said forming.
Claim 9
Independent Claim
108 words
The method of reinforcing container wall openings and providing identifying tag and closure seal affixing means comprising the steps of horizontally supporting a flat annular tag ring element having a central opening, horizontally positioning a container wall section in vertically spaced relationship below said tag ring element, performing said container wall to form an opening therein, drawing a neck in said container wall section upwardly about said opening, simultaneously drawing a neck upwardly from said tag ring element about the opening therein with said tag ring element neck closely surrounding said container wall opening neck and inserting an internally threaded closure flange within said container wall opening neck.
Claim 10
Independent Claim
108 words
The method of reinforcing container wall openings and providing identifying tag and closure seal affixing means comprising the steps of horizontally supporting a flat annular tag ring element having a central opening, horizontally positioning a container wall section in vertically spaced relationship below said tag ring element, performing said container wall to form an opening therein, drawing a neck in said container wall section upwardly about said opening, simultaneously drawing a neck upwardly from said tag ring element about the opening therein with said tag ring element neck closely surrounding said container wall opening neck and inserting an internally threaded closure flange within said container wall opening neck.
Claim 11
Dependent Claim
30 words
The method as in claim 7 and deforming said flange so as to permanently secure said flange and said tag ring element to said container wall about said opening neck.
