Definitions

  • the present invention relates to a container and a closure cap for said container and wherein container contents are dispensed through a metering orifice and said cap includes a pin which, when the cap is mounted in a closure condition, prevents discharge of container contents through said metering orifice.
  • Containers for flowable materials such as liquids, pastes, gels and powders, arranged to dispense such materials through a metering orifice to obtain controlled discharge of the container contents are well known in the art.
  • a serious disadvantage with such container and cap combinations is that, after a number of cap closures, wear between the pin and the metering orifice enlarge the metering orifice whereby said orifice no longer affords the desired controlled discharge and such enlargement of the orifice with wear on the pin renders the closure defective.
  • the Swiss Patent No. 426565 proposes a container structure in which the metering orifice discharges into an elongate conical chamber which increases in cross section towards that end remote from the metering orifice and the cap presents a conicla pin the taper of which is identical with the taper of the conical chamber.
  • the conical pin is entered into the conical chamber to prevent material flow from said chamber, and thereby from the metering orifice, without the pin contacting the metering orifice.
  • the container and cap combination proposed by Swiss Patent No. 426565 suffers from an inherent defect in that, as the conical pin is entering into the conical chamber to effect a closure, container contents in the chamber can be trapped between the tapered side of the pin and the tapered wall of the chamber, and as the pin advances into the chamber, the escape route for such trapped material is progressively lengthened and reduced in cross section. Whilst some low viscosity liquids can escape to permit full closure without undue axial pressure on the assembly such full closure cannot be obtained with liquids of higher viscosity or solids materials in powder or granular form.
  • the invention as claimed is intended to provide a simple design for a container closure and by which closure of the container metering orifice can be effected for most low pressure flowable materials without excessive loadings on the closure and without the danger of container contents being adversely trapped bwtween closure surfaces of the assembly.
  • a pin presented by a closure cap has a generally cylindrical form
  • a duct into which the metering orifice discharges has a cylindrical form
  • closure is effected by the cylindrical pin sliding piston-like into the cylindrical duct so that container contents in said duct are pushed ahead of the pin and, when substantial, back through the metering orifice.
  • the figures show in full line a first embodiment closure arrangement for a container C and, in broken line, a second closure arrangement for said container C.
  • a closure for a container comprises a closure cap 1 and a closure body 2,frictionally secured in the neck part 3 of container C.
  • the closure cap 1 and closure body 2 may conveniently be made of a semi-rigid plastics material by moulding processes.
  • the neck part 3 has an external thread 4 cooperable with an internal thread 5 formed in the closure cap 1.
  • the closure body 2 conveniently includes an applicator, illustrated as bundles of fibres 6 surrounding the discharge outlet from the container C.
  • the closure body 2 includes a metering orifice 7, in open communication with the interior of container C, and orifice 7 opens into a cylindrical duct 8 of larger cross sectional area than said orifice 7.
  • the container C, closure body 2, and, the closure cap 1 when in a closure condition, are, with the exception of threads 4 and 5 and bundles of fibres 6, concentric about a common axis A;A so that, as illustrated, metering orifice 7 and duct 8 are co-axial.
  • the open end of duct 8 (remote from orifice 7) has a chamfered or lead-in edg 9 and said end opens at an external face 10 of closure boby 2.
  • the metering orifice 7 and/or duct 8, may be formed in body 2 at moulding or subsequent thereto.
  • the closure cap 1 presents an axial pin 12 of such diameter as to slidably engage in duct 8 with minimal clearance and the free end of pin 12 is preferably hemispherical, as illustrated, to facilitate entry of said end into duct 8.
  • the closure cap 1 further includes an internal shoulder 13 intended to define an annular abutment surface which, when engaged with face 10 of the closure body 2 limits the axial advance of the closure cap 1 on the container neck 3.
  • the shoulder 13 lies in a plane P at right angles to axis A:A and the free end of pin 12 passes through plane P by axial length L which is slightly less than the axial length h of the duct 8.
  • container contents are discharged by removing closure cap 1 and tipping or flexing the container to cause the container contents to discharge through metering orifice 7 and duct 8 from which the container contents may be spread or smeared by fibres 6.
  • the closure cap 1 To close the container the closure cap 1 is mounted on the neck 3, the threads 4 and 5 are engaged and, by rotation of cap 1 relative to container (C) the cap is axially advanced onto the neck 3. With the threads 4 and 5 intially engaged the pin I? of cap 1 is axially located for entry into duct 8 and, as the axial displacement of cap 1 onto neck 3 progresses, the pin 12 enters duct 8 and axially advances thereinto. As pin 12 is a sliding fit with minimum clearance, in duct 8 the pin 12 acts in the manner of a piston and pushes container contents in duct 8 ahead of its free end and back towards metering orifice 7.
  • the bundles of bristles 6 are omitted and an annular wall 14 outstanding from surface 10 extends the axial length of duct 8 away from metering orifice 7 so that, all other parts and dimensions being the same as for the first embodiment, the closure operates in identical manner to the first embodiment with the exception that the pin 12 enters the duct 8 earlier in the advance of closure can 1 onto neck 3 and the axial length of pin 12 engaged in duct 8 when the cap is in its closure condition is greater.
  • Such an embodiment is well suited to a so-called "dropper" type dispensing container.
  • annnular wall 14 may be chamfered, as at 15, to assist entry of pin 14 into duct 8.
