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 refilling 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 refilling 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.
  • known fitments are those described in our Patent Specifications Nos: GB-B-2008531 and GB-A-2191754, and EP-A-0035918.
  • a non-refillable pourer fitment adapted to fit within the neck of a container
  • a non-return valve member adapted to permit the contents of the container to be poured out through the fitment but substantially to prevent flow into the container
  • the outer part is provided at or adjacent its outer end with an out­wardly directed annular flange adapted to overlie the rim of the container to which it is applied, or an in­ternal annular ledge thereof, a flexible outwardly directed annular fin formed on the outer part inwardly of the annular flange being adapted, on application of the fitment to the neck of the container, to be squeezed between the rim or ledge of the container neck and the flange on the outer part.
  • the annular fin is contacted by the rim of the container, or the internal annular ledge, and is deflected towards the annular flange. Further movement of the fitment into the container neck squeezes the annular fin between the rim or ledge on the container neck and the annular flange on the fitment, and forms a liquid-tight seal.
  • the annular flange on the outer part of the fitment is provided, at its radially outer extremity, with a flexible lip.
  • This may be formed around part only of the annular flange, thereby to act as a directional pourer, or it may be formed around the entire periphery of the annular flange, so that it acts as a secondary seal when a closure, e.g. a screw-type metal closure, is applied to the neck of the container.
  • the pourer fitment of the invention may take the basic form of that described in Specification GB-B-2008531 or GB-A-2191754, those fitments being modified by the provision of an annular flange and flexible annular fin at the outer end of the outer part.
  • the two parts of the pourer fitment are suitably moulded from a flexible and resilient polymeric material such as polypropylene or polyethylene, and may be attached to each other by snap-fitting.
  • the inner part of the fitment may be provided with an annular groove into which is snapped a corresponding annular bead formed on the outer part of the fitment.
  • the outwardly-directed annular flange formed on the outer part and adapted to overlie the rim of the container, or an internal annular ledge thereof suitably has a thickness in the range 0.6-1.2mm. preferably 0.8 to 1.0mm.
  • the flexible outwardly-directed annular fin formed on the outer part of the fitment suitably is of a thickness in the range 0.2-0.3mm. preferably 0.25mm.
  • the flexible lip formed on the annular flange which itself is preferably annular, and may be of tapered form, suitably has a mean thickness in the range 0.15-0.25mm.
  • a pourer fitment consists of an inner part 2 and an outer part 4 captively attached together.
  • the inner part 2 which retains a ball-shaped valve member 6 seated on a frusto-conical valve seat 8, is pro­vided at its upper end (when viewed in the normal direction of use) with an annular groove 10.
  • Snap-fitted into groove 10 is an annular shoulder 12 formed at the lower end of the outer part 4.
  • the parts 2 and 4 are moulded separately and thereafter snap-­fitted together.
  • the fitment is basically of the same form as that described in our Specification No: GB-A-2191754.
  • the outer fitment part 4 has at its inner end a longitu­ dinal bore formed of a first portion 14 merging through a frusto-conical ramp portion 16 into a second portion 18 of radius smaller than that of portion 14.
  • a cylindrical wall portion 20 surrounding a dispensing aperture 22.
  • Obturator disc 24 Centrally disposed of the fitment is an obturator disc 24 having a radius greater than that of bore portion 18.
  • Obturator disc 24 is attached to cylindrical wall 20 by means of four circumferentially-spaced stays 26, which are in effect moulded integrally with the wall and peripheral portions of the obturator disc 24.
  • Obturator disc 24 is also attached to four circum­ferentially-spaced pillars 28 at the upper end of the bore portion 18. The attachment between the obturator disc 24 and each pillar 28 is through a flexible frangible bridge 30.
  • an axially-extending peg 32 Centrally disposed on the underside of the obturator disc 24 is an axially-extending peg 32, which coacts with ball valve 6 to limit the movement of the ball valve in the inner part of the fitment.
  • Flexible annular ribs 34 cooperate with the inside of the neck of the container into which the fitment is inserted, to give a fluid-tight seal.
  • An additional seal is provided by an annular flange 36 at the upper end of the outer part of the fitment, and a cooperating flexible annular fin 38 formed therebelow.
  • annular fin 38 When the fitment is inserted into the neck of a container, the annular fin 38 is deformed and “squeezed" between the flange 36 and the rim or internal ledge of the container, as shown in Figure 2. This provides an effective secondary-seal, and a further seal is provided by a tapered annular lip 40 formed on the flange 36, which deforms into engagement with the radius at the mouth of the container.
