  • PLASTIC CONTAINER CLOSURE ASSEMBLY Filed Feb. 8, 1965 ATTORNEY United States Patent 3,353,849 PLASTIC CONTAINER CLOSURE ASSEMBLY Jeremiah Laurizio, New Buffalo, N.J., assignor to American Flange & Manufacturing (10., Inc., a corporation of Delaware Filed Feb. 8, 1965, Ser. No. 431,069 2 Claims. (Cl. 285-21)
  • This invention relates to container wall closure combinations and to methods for forming the same and is particularly concerned with synthetic plastic closure flanges and methods for securing the same within the openings in synthetic plastic container walls.
  • novel closure and method of applying the same as herein disclosed overcomes the prior art deficiencies by securing a plastic closure fitting about a plastic container wall Opening so that the resulting structure is an integral unit.
  • a zone of inherent structural weakness and a likely source of leakage has been transformed into a reinforced integral part of the closure equipped container. This is accomplished by actually flowing together adjacent portions of the closure fitting and container wall into a homogeneous zone of plastic material by the use of induction welding. It has been found that induction welding produces very good results when a metallic conducting element is employed within which current is induced thus generating sufficient heat to melt the adjacent plastic surfaces and to flow them together into a homogeneous zone of juncture.
  • Another object is to improve upon molded plastic closure fittings for containers.
  • Another object is to provide an improved method of securing closure fittings to container wall openings.
  • a further object is to provide an improved method for induction Welding of plastic closure fittings to plastic container wall openings.
  • a still further object is to provide a new and improved plastic closure fitting and metal conducting ring assembly adapted for induction welding to a plastic container wall.
  • a more detailed object is to provide a method of induction welding a plastic closure fitting and conducting ring assembly to a plastic container wall so that a com plete and homogeneous bond is formed therebetween.
  • FIG. 1 is a vertical section of a closure flange and conducting ring assembly positioned about a container wall opening prior to welding in accordance with the invention
  • FIG. 2 is an enlarged fragmentary vertical sectional view of the assembly of FIG. 1.
  • FIG. 3 is a view similar to FIG. 2 but with the assembly in welded position;
  • FIG. 4 is a fragmentary sectional view of a modified form of the invention prior to the welding operation.
  • the specific form of the flange 1 includes a cylindrical neck 2 having a laterally extending circumferential shoulder 3 at the upper end thereof.
  • the shoulder 3 is provided with a top surface 4, a peripheral outer edge wall 5 and a lower annular surface 6.
  • the neck 2 has a cylindrical outer surface 7, a lower end 8, and a threaded interior 9 having a plug seat 10 for reception of a plug 11 as shown in- FIG. 3.
  • a circumferential step 12 having a cylindrical surface 13 extending downwardly at 14 from the lower shoulder surface 6 and joining at the corner 15 in a downwardly facing annular surface 16 which in turn joins the outer cylindrical neck surface 7 at 17.
  • the container wall 17 to which the closure flange 1 is secured is also formed of a synthetic plastic material and has an opening therethrough provided with a cylindrical surface 18 extending upwardly from the lower surface 19 of the container wall and joining at 20 a conical surface 21 which extends upwardly and outwardly joining the upper wall surface 22 at 23.
  • FIG. 2 illustrates the relationship of the closure flange 1 and conducting ring 25 to the container Wall 17 prior to the welding operation performed by the surrounding coil 24.
  • the closure flange 1 is supported within the container wall opening by the conducting ring 25 which has an internal diameter substantially equal to the diameter of the cylindrical step surface 13.
  • the lower shoulder surface 6 contacts the upper surface of the ring 25 and is thus held spaced above the upper wall surface 22.
  • the ring in turn bears against the conical container wall surface 21 adjacent the upper end 23 thereof.
  • the induction heating coil 24 is here shown as a ring of copper tubing which surrounds the conducting ring 25 in operative relationship thereto.
  • the conducting ring 25 Upon initiation of the welding cycle the conducting ring 25 is heated well beyond the melting point of the plastic material causing the ring to partially embed itself in both the lower shoulder 6 and the conical flange surface 21.
  • the flange 1 accordingly settles downwardly within the container wall opening due to the melting away of the opposing surfaces above and beneath the ring 25. As the flange drops or settles, a slight downward force on top of the flange may be used to assist in this movement.
  • the step formation 12 also melts commencing with the cylindrical surface 13 which initially lies in contact with the ring 25. The plastic material thus melted flows into and fills the pocket formed above the lower end of the conical surface 21 and in addition, flows down into the space 26.
  • the flange lower shoulder surface 6 contacts the upper container wall surface 22 with the lower end 8 of the flange neck in alignment with the lower container wall surface 19.
  • This fusion zone in effect creates an integral flange container wall construction possessing all the inherent advantages thereof. More specifically, the connection hereby formed may be subjected to internal pressures limited only by the strength of the container wall itself. Similarly, resistance to rotational torque between the flange and container wall is also limited only by the shear strength of the container wall material. Furthermore, any damaging differential shrinking or swelling of the respective parts is eliminated.
  • FIG. 4 A modified form of the invention is shown in FIG. 4 comprising a container wall section 30 and a flange member 31.
  • the relationship between the metal conducting ring 25 and the heating coil 24 is substantially the same as in the preferred form, however, here the container wall opening is bordered by a step having a vertical wall 32 and a horizontal annular step surface 33.
  • the ring 25 is thus between the annular step surface 33 and the under surface 34 of the flange shoulder 35.
  • a container wall molded of synthetic plastic material formed with an opening therethrough, a closure flange molded of synthetic plastic material comprising an interiorly threaded cylindrical neck terminating at one end in a circumferentially enlarged shoulder said shoulder having a flat upper surface, a lower annular surface and an outer edge, an annular projection at the juncture of said lower shoulder surface and said cylindrical neck, a metal conducting ring surrounding said flange neck and engaging said lower shoulder surface and said annular projection.
  • a closure member molded of synthetic plastic material comprising a cylindrical neck terminating at one end in a circumferentially enlarged shoulder, said shoulder having a flat upper surface,, a lower annular surface and an outer edge, a right angled annular step at the juncture of said lower shoulder surface and said cylindrical neck, and a metal conducting ring surrounding said flange neck and engaging said lower shoulder surface and the radially outwardly facing wall of said step.
