Definitions

  • This invention relates in general to the dispensing of liquid or plastic materials from flexible containers, and in particular to novel perforating nozzles for use therein.
  • nozzles made in accordance with the principles of the present invention find particular application in the encapsulation of wire-splices as described in US. Patent No. 2,967,795.
  • the enclosed splice area is forcefully encapsulated with solidifiable liquid resin applied under pressure from a flexible envelope or bag in which the resin is mixed just prior to application.
  • the bag containing the mixed resin is placed within a pressure-gun, an opening leading to the splice enclosure is provided, and the resin is forced from the container into the enclosure and around the splice by the action of the gun.
  • the present invention provides a nozzle member which may be attached to the hermetically sealed bag or envelope prior to placing the same in the pressure-gun.
  • the nozzle provides leak-proof positive connection to the entry port of the splice enclosure. It is rigidly held in the gun.
  • the envelope remains sealed until pressure is applied, whereupon the film is perforated by the nozzle to permit flow of the resin from the envelope into the splice enclosure under extreme pressure and without loss or leak-age.
  • the nozzle permits essentially complete transfer of resin from envelope to splice area regardless of accidental or unavoidable folding or displacement of the plastic film container-wall across the inner end of the nozzle.
  • FIGURE 1 is a side elevation of a perforating nozzle showing one means for attaching the same to an envelope;
  • FIGURE 2 is a front elevation of the nozzle of FIG- URE 1, partly in section and illustrating an alternative attaching means;
  • FIGURE 3 is a bottom plan view
  • FIGURE 4 is a partial sectional view, of the nozzle of FIGURES 1 and 2.
  • the nozzle 18' may be conveniently and economically formed of hard synthetic resin, high impact transparent polystyrene resin being a preferred material. Preferably, it is adherently attached to the resin-containing envelope by means of an overlapping centrally apertured diskshaped or diamond-shaped segment of pressure-sensitive plastic film adhesive tape 11 applied with the adhesivecoated surface downward as indicated in FIGURE 1, or by an annular ring of double-coated tape 12. comprising a thin compressible carrier web coated on both surfaces with pressure-sensitive tape adhesive and adherently attached as shown in FIGURE 2.
  • a typical nozzle having the relative proportions of the drawing will be just slightly more than two inches in length.
  • the tubular body 13 of the nozzle is desirably provided at one end with self-tapping external screw threads 14 for leak-proof connection with a comparatively soft tubular injection port member at a splice area.
  • the disk 15 has a fiat upper surface as seen in FIG- URES l, 2 and 4, and a lower surface tapering from the rim of the ring to the base of a circular triangularly cross- 3,lll,2d Patented Nov. 19, 19x33 2 sectioned blocking ring 19.
  • the slotted tube 16 extends appreciably below the ring 19 which in turn extends somewhat below the inner flat lower surface 2% of the disk 15.
  • the lower outer surface of the body 13 is provided with two opposed locking projections '21 and two opposed handle fins 22 also serving as locking projections.
  • Members 2'1 and 22 are equidistantly spaced from the upper surface of disk 15 a distance sufiicient to permit the nozzle to be inserted and tightened into an appropriately radially slotted and cammed pressure gun end cap.
  • the nozzle assembly is adherently attached to a smooth surface of the resin-containing envelope and with the extended cutting edges '18 of the tubular extension 16 pressing gently against the smooth film surface.
  • the envelope is placed Within the open cylinder of the pressure-gun.
  • the nozzle is drawn through the centrally open end cap which is radially slotted and ofiset to receive the projections 21, 22. in the manner of a quick-acting screw connection.
  • the cap is attached over the open end of the cylinder, and the nozzle is tightened in place by twisting.
  • the fiat upper surface of the disk 15, with or without the intervening thin plastic tape 11, is thereby held tightly against the inner surface of the cap.
  • the threaded end of the nozzle is screwed into the injection port member or otherwise held in position for delivery of resin.
  • one or more folds in the film body of the envelope may fall across the open end of the tube 16 and even across the entire area surrounded by the ring 19, but without blocking access by the remaining resin to the open annular channel surrounding the tube 16 because of the extension of the tube below the level of the ring.
  • the slots 17 provide for passage of the resin to the hollow center of the nozzle.
  • a film-perforating nozzle suitable for use in the dispensing of liquid contents from plastic film containers and comprising a generally tubular body including a base having an exposed broad annular film-retaining surface, a sharp-edged thin tubular extension of said tubular body extending beyond and centrally of said film-retaining surface, said body being annularly channeled between said surface and said extension, said extension being provided with open passages adjacent the channeled areas.
  • a film-perforating nozzle suitable for use in the dispensing of liquid contents from plastic film containers and comprising a generally tubular body including a base having an exposed broad annular film-retaining surface, a longitudinally slotted sharp-edged thin tubular extension of said tubular body extending beyond and centrally of said film-retaining surface, said body being annularly channeled between said surface and said slotted extension.
  • a nozzle suitable for attachment to a flexible plastic film envelope comprising a generally tubular body having a radially extended annular fiat base provided with a ringed surface for contact with said envelope, a longitudinally slotted thin tubular extension of said tubular 3 body extending beyond and centrally of said ringed surface, said body being annnlarly channeled between said ringed surface and said slotted extension.
  • a film-perforating nozzle suitable for attachment to a plastic film container in the dispensing of liquid contents therefrom under pressure in a pressure-gun and comprising a generally tubular body having near one end an extended planetary disk-shaped base including on its outer flat face a raised angularly cross-sectioned ringshaped projection uniformly surrounding the longitudinal nozzle axis, a longitudinally slotted sharp-edged thin tubular extension of said tubular body extending beyond said base, said body being annularly channeled between said slotted tubular extension and said ring-shaped proto a pressure-gun cap.
