Definitions

  • This invention relates to fitments for bottles and other containers, and particularly to such fitments which allow the contents of the container to be dispensed by pouring but prevent the re-filling of the container.
  • fitments are generally known in the art as “non-refillable pourer fitments”.
  • Such fitments are particularly used in the spirits trade, for example on whisky and gin bottles. It is not unknown for such bottles to be tampered with, for example by emptying a proportion of their contents and re-filling them with, say, water.
  • the use of non-refillable pourer fitments to a substantial extent prevents this tampering with the contents of the bottles, whilst allowing those contents to be freely dispensed.
  • non-refillable pourer fitments are known and used, and they vary in effectiveness. Thus, with certain fitments it is necessary to provide special closure caps to fit over or around the fitment and the container neck; with other fitments, it is possible to "poison" the contents of the containers by means of a high-pressure jet of liquid strategically aimed through the fitment; other fitments can be removed from the bottles by means of hooks or other tools.
  • the fitment described in our Patent Specification No. GB-B-200853l overcomes all these problems. It comprises a non-refillable pourer fitment for the neck of a container comprising inner and outer parts captively attached to each other, a valve member located and movable in a longitudinal bore in the inner part and the outer part being formed with a longitudinal bore at its inner end and a dispensing aperture at its outer end, the longitudinal bore in the outer part varying in radius along its length from a portion of relatively large radius to a portion of relatively small radius, an obturator disc intermediate the portion of relatively small radius and the outer end having a radius greater than the relatively small radius, and being attached to the outer part by at least one frangible stay.
  • Bottles are, of course, filled and capped at high speed, and care must be taken with fitments of the relatively complicated and sophisticated type of those described in Specification GB-B-200853l to ensure that the frangible stays connecting the obturator disc to the outer fitment part do not break during insertion of the fitment into a bottle. It is the object of the present invention to provide a fitment wherein this possible drawback is avoided.
  • a non-refillable pourer fitment for the neck of a container comprising inner and outer parts captively attached to each other, a valve member located and movable in a longitudinal bore in the inner part and the outer part being formed with a longitudinal bore at its inner end and a dispensing aperture at its outer end, the longitudinal bore in the outer part varying in radius along its length from a portion of relatively large radius to a portion of relatively small radius, and an obturator disc intermediate said portion of relatively small radius and said outer end and having a radius greater than said relatively small radius, in which the obturator disc is attached through frangible bridges to a series of pillars spaced circumferentially around the said outer part, the bridges being sufficiently flexible as to allow said disc to contact the tops of said pillars when pressure is appli ed to said fitment at its outer end during insertion into the container neck.
  • the pourer fitments of the present invention thus suitably consist of three separately formed parts which are subsequently assembled together, namely outer and inner parts and a valve member.
  • the outer and inner parts are preferably made of plastics material, such as for example polyethylene, polypropylene or polystyrene, and are suitably shaped such that they may be snap-fitted together, for example by means of one of the parts having an annular rib which snaps into and is retained in an annular groove formed in the other part.
  • the valve member is suitably a glass or steel ball the limit of whose movement towards the pouring outlet of the fitment is suitably controlled by a peg integrally formed with the outer part of the fitment.
  • the pourer fitment of the invention is preferably provided with one or more flexible sealing ribs which in use provide a tight seal against the inside of the bore of the container into which the pourer is fitted.
  • These sealing ribs may be formed integrally with either the outer or the inner part of the fitment.
  • the fitment comprises an inner part not shown, but suitably of a form similar to that shown in Figure 4 or Figure 5 of Patent Specification GB-B-200853l and an outer part l0 captively-associated by a snap-fitting engagement with the inner part.
  • Both the inner and outer parts are mouldings of plastics material, for example polyethylene, polypropylene or polystyrene.
  • outer part l0 The lower end of outer part l0 is provided with an annular bead ll which is snap-fittedly engaged in a complementary groove in the inner part.
  • Outer fitment part l0 has at its inner end a longitudinal bore formed of a first portion l2 merging through a frusto-conical ramp portion l3 into a second portion l4 of radius smaller than that of portion l2.
  • a cylindrical wall portion l5 surrounding a dispensing aperture l6.
  • obturator disc l7 Centrally disposed of the fitment l0 is an obturator disc l7 having a radius greater than that of bore portion l4.
  • Obturator disc l7 is attached to cylindrical wall l6 by means of four circumferentially-spaced stays l8, which are in effect moulded integrally with the wall l6 and peripheral portions of the obturator disc l7.
  • Obturator disc l7 is also attached to four circumferentially-spaced pillars l9 at the upper end of the bore portion l4. The attachment between the obturator disc l7 and each pillar l9 is through a flexible frangible bridge 20.
  • obturator disc l7 Centrally disposed on the underside of the obturator disc l7 is an axially-extending peg 2l, which coacts with the valve member in the inner part of the fitment (not shown) to limit the movement of that valve member, in the manner shown in Specification GB-B-200853l.
  • Flexible annular ribs 22 and 23 cooperate with the inside of the neck of the container into which the fitment is inserted, to give a fluid-tight seal.
