Definitions

  • This invention relates to closure members of the type wherein a plug of resilient material is opened by perforation with a hollow needle and is closed by its own resilience upon withdrawal of the needle.
  • Receptacles utilizing such closure members nd wide commercial use due to their convenience and expendability whereby the receptacle may be disposed of after its contents have been emptied. Because of this, cost has become a prime consideration and since these receptacles are used in large quantities, even very small reductions in the cost of manufacture per unit may be of considerable overall significance.
  • receptacles of the type to which the improvements of the present invention are applied have at one end a tubular spout or nozzle which houses near its outer tip a plug of resilient material.
  • a special machine having specially designed guide means must be provided in order properly to position the plug within the spout or nozzle.
  • the plug is generally retained in place by a metal washer which is introduced into and crimped inside the spout or nozzle.
  • One of the advantages of the present invention lies in the fact that the cost of manufacture of this general type of closure member is considerably reduced.
  • a tubular part such as a spout or nozzle, one end of which is closed by a plug of flexible, resilient material, said plug being adapted for perforation by a hollow needle or other perforation element and further adapted to se-al the perforation itself by its own resilience after withdrawal of the element.
  • the outer tip of the tubular part is formed with a shoulder which extends inwardly of the part and acts as a stop to retain the resilient plug.
  • the inner diameter of the tubular part is large enough to permit introduction of the plug through that end thereof which is remote from the end formed with the retaining shoulder.
  • FIG. 1 is a side view, partially broken away, of a receptacle utilizing a closure member of the present invention.
  • FIG. 2 is a section View of the end of the receptacle of FIG. l.
  • FIG. 3 is a view of the tip of the spout portion of FIG. 2 showing one modification.
  • FIG. 4 is a section view similar to FIG. 2 showing another modification.
  • FIG. 5 is Ia View similar to FIG. 3, showing a still further modication.
  • the receptacle shown in FIG. 1 comprises a spun cylindrical tubular body 1 having a bottom end 2 formed in one piece therewith.
  • the other or open end of the body 1 is closed by a metal stamping ⁇ 3, the shape of which is best illustrated in FIG. 2.
  • the stamping 3 has a central tubular part 4 whose outer tip is bent over to form an annular shoulder 5 adapted to retain a plug 6 of resilient material.
  • the tubular part 4 is rigidly connected to a wall portion 7 having a bent over edge 8. This bent over edge is crimped over a gasket and a rolled edge 9 at the open end of the cylindrical body 1 (FIG. l) to form a pressure tight seal therewith.
  • the tubular part 4 is formed with a larger inside diameter portion 21 near the bottom thereof which connects through a generally frusto-conical surface 22 to a smaller diameter portion 20 which extends in a slight taper to the outer tip of the part.
  • This arrangement is advant-ageous for manufacture since it enables the plug 6 to be tted accurately and easily simply by pushing it in through the bottom end of the tubular part 4 which acts as a kind The machine which lits the plug therefore does not have to be provided with a guide element for maintaining proper orientation and alignment.
  • la ring or annular part 10 is forced inside the tubular part 4 behind the plug and prevents excessive axial displacement of the latter.
  • an axial clearance is provided between the ring or annular part 10 and the plug 6.
  • the plug has a normal unstressed outer diameter slightly larger than the smaller inside diameter at the tip portion of part 4, so that after the plug has been introduced into the latter it undergoes radial compression.
  • This provides sealingtightness between the plug and inside wall of the tubular part, and further it sets up residual stresses within the plug which effect automatic sealing of apertures which are formed in the plug by insertion of a hollow needle or other perforation element.
  • FIG. 3 shows a variant of the arrangement at the tip of the tubular part 4 wherein the plug 6 is pressed axially over its periphery by an annular part 11 forced into the tubular part 4.
  • the normal unstressed outer diameter of the plug is slightly smaller than the inside diameter of the end of the tubular part 4 so that the crushing of the plug edge due to the axial pressure exerted by the ring 11 develops a radial displacement of material in the plug and brings its periphery into contact with the inside wall of the tubular part 4 so as to provide the required Y sealing-tightness.
  • FIG. 4 shows a modified form of the end part of the receptacle of FIG. l.
  • an end closure formed of a stamping 12 having its central portion adapted to receive a tubular part 13 of molded synthetic resin.
  • the tubular part 13 is formed with a collar 14.
  • a gasket 15 is fitted over the collar and the two are rmly attached in sealing tight relationship to the stamping by the crimping of its central portion over these parts.
  • the tip of the tubular part 13 has an annular lip 16 facing the inside of the tubular bore and forming a shoulder for a plug 17 of flexible resilient material.
  • the plug is introduced intothe part 13 through its Vbottom opening. This bottom opening, as in previous embodiments,
  • the plug has a larger-diameter portion, designated at 18, which' acts in the nature of a funnel to facilitate the introduction of the plug 17.
  • the plug is simply placed in the larger diameter portion 18, and then is pushed into the tubular bore of the part 13 by a punch, with resultant radial compression of the plug due to a slight taper or reduction in the inside diameter of the part 13. This operation can be carried out without any guide means for pre-compression of the plug before its-introduction.
  • the plug 17 is retained by a tube 19 forced inside the tubular part 13. This tube is inserted to a point which leaves a given space 32 between the lip 16 and the end of the tube 19. This space is greater than the thickness of the plug 17 so as to provide a sufficient free volume to receive the material of the plug displaced on introduction of the perforation element.
  • the plug introduction operation can be simplified further by introducing the plug into the tubular part 13 at the same time as the tube 19 is inserted and the two can be forced into place in a single operation.
  • FIG. shows a still further modification of the arrangement at the tip of the tubular part 4.
  • the tubular part is formed of a metal stamping as described previously with reference to FIGS. 2 and 3, and has its tip folded over to form a shoulder 5 which retains the plug 6.
  • This stamping is further provided with an annular constriction 23y at a distance from the tip, this constriction forming an internal retaining shoulder for the plug 6. Since this shoulder has a rounded shape, it is possible to introduce the plug 6 through the rear aperture of the tubular part 4 and push it up past this shoulder to fit it in the position shown in FIG. 5. The plug is thus situated between two shoulders and a retaining part does not have to be introduced into the tubular part 4.

  • a plug of exible and resilient material closing one end of said tubular part said plug being adapted for perforation by a perforation element and further adapted to seal the perforation by its resilience after withdrawal of such element, the outer tip of said tubular part having an integral shoulder serving as a stop for retention of said plug inside the tubular part, said tubular part further having an inner diameter such as to permit introduction of said plug through that end of the tubular part which is remote from the outer tip having the said shoulder;
