Definitions

  • This invention relates to containers and closures therefor and is particularly concerned with a lightweight container wall and closure assembly combination providing improved torque resistance.
  • 217,483 constituted an improvement thereover in that, besides disclosing various other closure assemblies secured to said neck formation, it also discloses improvements in the securing formation of the closure assembly as well as in the combination of the neck formation and the closure assembly for the effecting of an improved closure.
  • both the opening neck and the flange in the invention construction have been so located as not to detract in any way from the eflectiveness of the plug gasket seat on the flange or the seal formed between the flange and the opening neck.
  • the entire cross sectional wall has been fully utilized so that each portion thereof has a specific purpose contributing toward a light, compact, and extremely effective closure.
  • the polygonal formation in both surfaces has been located so as to impart a high degree of strength and rigidity to the combination, which factor increases in importance with the achievement of increased torque resistance.
  • Another object is to provide an improved container opening neck formation.
  • Another object is to provide a closure assembly-container wall combination having improved torque resistance.
  • a further object is to provide an improved closure assembly-container wall combination having matching polygonal surfaces.
  • a still further object is to provide a closure flange having a polygonal surface which can be easily matched up with a polygonally formed opening neck upon application thereto.
  • FIG. 1 is a sectional view of a container wall opening closure assembly combination in accordance with the invention.
  • FIG. 2 is a top plan view partially .cut away of the container wall opening and closure flange.
  • FIG. 3 is a sectional view taken on lines 3-3 of FIG. 2 and looking in the direction of the arrows.
  • FIG. 4 is a sectional view taken on lines 4-4 of FIG. 2 and looking in the direction of .the arrows.
  • FIG. 5 is an enlarged fragmentary section showing the closure flange placed on the container wall opening in matched but unsecured position.
  • FIG. 6 is a sectional view showing the flange engaged Within the opening neck in unmatched position.
  • closure assembly itself has as its main parts a closure flange 1, a closure plug 2, details of which latter can be had by reference to co-pending application Serial No. 216,809 of Walter J. Pentesco ens earer titled Closure Plugs and Methods for Making Same filed on Aug. 14, 1962 the same assignee as this application, and a capseal 3.
  • the capseal 3 is also the same as that shown on application Serial No. 217,483 with the exception that the present capseal has a small flowed in gasket 4 located at the juncture of the skirt 5 and the disc-like top 6. The primary function of this gasket is to prevent any water from gaining access to the recessed plug 2 from the outside.
  • the above generally described assembly is provided as a complete unit by the manufacturer thereof and is applied to a container wall opening after the container has been filled as more fully discussed in application Serial No. 217,483 and Serial No. 230,786.
  • the flange generally indicated at 1 comprises a securing formation generally indicated at 7 and FIG. 5 forming the peripheral portion thereof and having a first upwardly and slightly outwardly tapered portion 8, a second portion 9 extending in an upward and outward incline from the upper end of the first portion, a rounded upper portion 10 and an outer peripheral wall 11 extending downwardly from the rounded portion 10.
  • the present closure flange 1 is improved over that disclosed in application Serial No. 217,483 by having the first portion 8, in addition to hav ing a slight taper for a reason to be fully discussed subsequently, having a polygonal cross sectional configuration formed therein.
  • a sixteen sided formation has been found to be most advantageous here in order to obtain maximum torque resistance while at the same time facilitating matching of the flange with the container wall opening.
  • the sides and corners of the polygon are indicated respectively by numerals 12 and 13.
  • the flange 1 Extending radially inwardly from the lower end of the securing formation 7, the flange 1 has an annular web 14 which has at its inner periphery a downwardly and in wardly inclining gasketing portion 15 and a downwardly extending threaded wall 16. Threadedly engaged with the neck is the plug 2 with its accompanying gasket 17 as described in application Serial No. 217,483.
  • the container wall 20 has an opening with an upstanding neck generally indicated at 21 therearound.
  • This neck formation also improved upon that disclosed in application Serial No. 217,483, is formed with a first curved portion indicated generally at 22 extending upwardly from the container wall.
  • the formation continues from the curved portion 22 directly into a doubled over portion having an upwardly and outwardly extending first part 23, a rounded upper end or head 24 and a downwardly and inwardly extending second part 25.
  • the second part overlies and tightly engages the first part 23 throughout its length so that the doubled portion having parts 24 and 25 has a frusto conical form extending from the curved single thickness portion 22 at an angle of substantial extent with respect to the axis of the opening.
  • FIG. 2 it can be seen that there is formed on the interior of the first curved portion 22 of the neck, a surface having a sixteen sided polygonal cross sectional configuration similar'to that formed in the flange.
  • the sides and corners of this polygonal section are indicated by numerals 26 and 27 respectively in FIGS. 3 and 4 wherein it can be seen that the polygonal surface varies in depth from a relatively narrow area at the center of 'the sides 26 to a much greater depth at the corners 2'7 which extend from a point 28 at the bottom surface of the container wall to a point 29 at the approximate juncture of the first curved portion 22 with the upwardly and outwardly extending first part 23.
  • the only areas representing the first upwardly curved portion 22 are the rounded portions 30 lying above and below the sides 26.
  • the rounded portions 30 and the slight inclination of the respective polygonal surfaces enables registering of the parts to be easily effected by the exertion of light rotational force applied to the closure in the event that, when placed in the opening, the closure assembly is initially unmatched with the neck formation. It can also be seen in FIG. 5 that, as the closure assembly is urged downwardly by the sealing tool, shown in detail in application Serial No. 217,483, a wedging action takes place between the flange and the neck due the self-locking taper formed in the matching polygonal portions. This self-locking taper in the respective surfaces is such that when the assembly reaches its fully seated position shown in FIG.
  • a tight joint is formed which creates a partial seal between the opposed metal surfaces in addition to that provided by the gasket Sill on the head 24. Further there is provided a strong supporting surface against which the opening neck is urged when the jaws of the sealing tool crimp the capseal skirt 5 and underlying peripheral wall 11 inwardly around the outer surface of the opening neck.
  • the combined structure is such as to provide a positive metal to metal contact between container wall and the flange at the position 32 and the head of the plug and the flange at the position 33 resulting in a rigid wall across the entire closure area.
  • the respective cross sectional walls of both the flange and the opening neck have been utilized to their fullest extent with each minute portion serving an important function.
  • the polygonal walls are such as to impart a high degree of stiffness and rigidity to the combination while at the same time detracting in no way from the effectiveness of the leakproof seal formed between the flange and the neck or between the flange and the plug.
  • Most importantly, of course, is the greatly improved torque resistance which is achieved due to the matching polygonal surfaces representing a substantial improvement over the arrangements disclosed in the above mentioned co-pending applications.
  • H6. 6 is shown to illustrate the relative position of the flange and neck when the clinching operation takes place with the parts inadvertently placed in an unmatched position.
  • a container wall opening neck formation comprising a first outwardly curved portion of a single thickness of container wall material extending upwardly from said container wall and a doubled over second portion formed as an extension of said first portion and extending outwardly and upwardly from said curved portion in frusto conical form at an angle of substantial extent with respect to the axis of said opening, said second portion having an upwardly and outwardly extending first part, a rounded upper end and a second part extending downwardly and inwardly from said rounded end, a surface formed within the confines of said first outwardly curved portion having a slight upward and outward incline with respect to the axis of said opening and having a polygonal cross-sectional configuration when viewed in the plane of the opening, said polygonal surface diminishing from a maximum height at the corners to a minimum height at the midpoint between the corners.
  • a lightweight closure flange formed as an annular member having a securing formation forming the peripheral portion of said flange, said securing formation having a first upwardly extending portion, a second portion extending upwardly and outwardly from the upper end of said first portion, a rounded upper portion and an outer portion extending downwardly from said upper portion adapted to be formed inwardly around an upstanding container wall opening neck formation, said first upwardly extending portion having a slight upward and outward incline with respect to the axis of the opening and having a polygonal cross sectional configuration when viewed in a plane transverse to the axis of said annular member, an annular web extending radially inwardly from the lower end of said first portion of said securing formation, and a screw threaded neck formed with a dispensing opening therethrough extending from the radially innermost portion of said web.
  • a lightweight closure flange formed as an annular member having a securing formation forming the peripheral portion of said flange, said securing formation having a first upwardly extending portion, a second portion extending upwardly and outwardly from said first portion, a rounded upper portion and an outer portion extending downwardly from said upper portion adapted to be formed inwardly around an upstanding container wall opening neck formation, said first upwardly extending portion having a polygonal cross sectional configuration when viewed in a plane transverse to the axis of said annular member, an annular web extending radially inwardly from said first portion of said securing formation and a screw threaded neck formed with a dispensing opening therethrough extending from said web.
  • a container wall opening assembly combination comprising a container wall formed with an opening therein and a closure assembly secured thereto, said opening having a bordering formation in the form of a neck formed integrally from the stock of said container wall surrounding said opening, said opening neck including a first outwardly curved portion of a single thickness of container wall extending upwardly from said container wall and a doubled over second portion formed as an extension of said first portion and extending outwardly and upwardly from said first portion in frusto conical form at an angle of substantial extent with respect to the axis of said opening, said second portion having an upwardly and outwardly extending first part, a rounded upper end and a second part extending downwardly and inwardly from said rounded end, a surface formed within the confines of said first outwardly curved portion having a slight upward and outward incline with respect to the axis of said opening and having a polygonal cross sectional configuration when viewed in the plane of the opening, said polygonal surface being of a greater depth at the corners than
