  • the pins 81 are located in the embossing surface 78 at diametrically spaced positions at the corners of the octagon so as to line up with the tag ring eyelets 10.
  • FIGS. 19 and 20 show a modified embossing ring 175 which provides for retention of an octagonal tag ring element 7 by friction fit engagement in place of the spring pins above described.

  • Two diametrically opposed flats of the octagonal wall 178 have downwarldy and radially inwardly tapered portions 181 so dimensioned that the distance between the lower ends of the tapered portions 181 is slightly less than the dimension across the flats of the tag ring element. Accordingly, as the tag ring element 7 is pushed up into the embossing ring 175 by the upper plunger 42, that element is slightly flexed across the two flats engaging the tapered embossing ring portions 181. This allows the tag ring element to snap within the embossing ring wall 178. The hodling effect here is adequate to retain the tag ring element 7 within the embossing ring during the insertion stroke.
  • the cutaway section thereof shows the finished tag ring element 7 formed to closely surround the underlying container wall opening neck 93 thus acting as an effective thickening and desirable reinforcement of the container wall neck surrounding the flange.
  • This is particularly advantageous in the case of light gage metal containers where the tag ring element may even be formed from material considerably heavier than the container wall in order to adequately support the inserted flange in the drum neck. It may even be desirable in certain instances to eliminate the container wall opening neck all together and utilize the tag ring neck formed in accordance with the invention as the sole securing neck for securing flanges with respect to container walls.
  • the tag ring free edge 9 is spaced slightly upwardly, as indicated at 94, from the border of the underlying container wall embossment 93.
  • the gap 94 is partially created during the insertion operation by the container wall metal being pulled over the sharp edge of the flange base 5 at a sharper radius than the radius to which the tag ring element outer edge is formed by the radiused juncture portion in the embossing ring.
  • the gap 94 is also contributed to by a certain amount of vertical spring back which naturally occurs along the edge 9 upon the release of the pressure of the embossing ring.
  • the purpose of the gap 94 is to provide accessibility to the tag ring eyelets 10 through which a string or wire can be secured carrying a tag for identifying the container contents.
  • a wire and lead closure seal can also be employed by threading a wire through an eyelet of a closure plug (not shown) threadedly engaged in the flange 1 then threading it through one or more of the eyelets l0 and clinching its ends within a lead seal.
  • the gap 94 normally sufficiently exposes the eyelet 10 for threading of a thin wire therethrough. If not, the gap provides an easy access point to insert an implement for deflecting the tag ring element edge 9 upwardly to expose the eyelet far enough for the insertion of even a heavier wire through the eyelet 10.
  • Tag ring element Formation of the tag ring element outer edge portion of the manner shown, allows the tag ring element to advantageously perform its intended function without presenting any sharp or protruding metal edges to injure one s hands. Any hazard attendant to the common practice of wiping off the top of the container around the closure opening is prevented.
  • FIGS. 23 A further modified tag ring element and embossing ring for holding the same are illustrated in FIGS. 23
  • the tag ring element 207 is shown as a flat blank having a circular inner edge 208 and a circular outer edge 209 interrupted by a pair of radially outwardly protruding, diametrically opposite ears 211 formed with eyelets 210. It should be noted that the tag ring element 207 could also be fabricated with a partially preformed neck as shown in the modified tag ring element 107 of FIG. 12. In FIGS. 24 and 25, the tag ring element 107 is shown as pressed up within a modified embossing ring 275 having a lower embossing surface 277 and an upper embossing surface 279 joined together by a vertical octagonal wall 278.

  • the tag ring element 207 is worked into its final form in the course of the insertion operation as abovedescribed. However, the tag ring element outer edge 209 lies within the confines of the underlying octagonal container wall embossment 92, as seen in FIG. 23, while the ears 211 extend past the outer edge of the embossment to overlie the surrounding container wall in spaced relationship with respect thereto.
  • the tag ring element can be automatically fed into and held in the upper die sub-assembly of either the first or second operation die and formed over the container wall opening neck and surrounding embossment, resulting in the finished assembly of completed tag ring element, flange and drum stock as shown.
  • 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 tainer wall and said tag ring element during said secur- 4.
