Definitions

  • the present invention relates to a container for a fluid and a closure member therefor including a brush or brush holder portion.
  • Such an arrangement may be utilised, for example, to apply a fluid from inside the container directly to the brush and in a particularly preferred embodiment the brush is used to clean false dentures.
  • containers which include brushes and which are often used in a domestic environment to contain fluids which may be for example, corrosive (for example the fluid used to clean false dentures) or to contain paint, for use, for example by children, that the container and closure member form a very effective seal which is not influenced by manufacturing variations and tolerances.
  • fluids which may be for example, corrosive (for example the fluid used to clean false dentures) or to contain paint, for use, for example by children, that the container and closure member form a very effective seal which is not influenced by manufacturing variations and tolerances.
  • the passageway 42 has to include a bend therein since at its upper end adjacent nozzle 44 it must extend axially and at its lower end it must extend transverse the axis. Such a passageway cannot easily and economically be moulded.
  • the present invention provides a container which meets the above problems and disadvantages of the prior US Specification 3118578.
  • the present invention provides a contalner such as a bottle, closed tube or the like, for a fluid comprising:
  • the longitudinally extending portion may be coaxial with the neck portion or may be at an angle to the neck portion.
  • the fluid connection bore because of the use of a brush can extend in a straight line between the sealing outer surface and the brush holder portion which simplifies manufacturing.
  • the container of the invention provides a very practical arrangement which is not only excellent in use but also facilitates manufacture.
  • the words "flow control” have a broad meaning in the present specification.
  • the words cover accurate control of the flow of a fluid in which the various parts would need to be accurately dimensioned or alternatively, the restriction of the flow of the fluid from the interior of the container so as to prevent too much passing out of the container in normal use in which case normal manufacturing tolerances would suffice.
  • a dispenser which includes an arrangement for preventing too much liquid from being passed out of the container by the user and this may be particularly useful in dispensing liquid from bottles of toiletries such as perfumes, shampoos and denture cleaners.
  • FIG. 1 there is illustrated a container 10 having an opening 11 surrounded by an upstanding neck 12.
  • the container which is for fluid may be of any suitable material but may preferably be a bottle moulded of flexible plastics material, the neck 12 being closed by a closure member 13 at the top of which is mounted a brush holder portion 14.
  • the type of brush and the manner of its stapling to the brush holder portion 14 is illustrated in our earlier British patent no. 1,502,942.
  • the neck 12 is of generally cylindrical form there being provided a cylindrical inside surface portion 16a and an upper outwardly tapering inside surface portion 16 which extends to the upper end of the neck portion 12.
  • Moulded in this tapering inside surface portion 16 is a depression in the form of a channel 17 having an axial length illustrated in Figure 1 (note it does not extend to the top of the neck 12 but does extend to the bottom of the tapering inside surface portion 16) and a cross section illustrated in Figure 2 or Figure 3 ( Figure 3 is clearer).
  • the channel 17 extends generally downwardly towards the interior of the container 10 to at least the bottom of the tapered inside surface portion 16.
  • the channel 17 by virtue of its small size and being formed in the outwardly tapering surface portion may be easily formed and the mould may be easily withdrawn without damaging the remainder of the outwardly tapering inside surface portion.
  • the outer surface of the neck 12 includes a circumferential rib 18 and, at the base of the outer surface of the neck, two stop members 19,20.
  • the closure member 13 comprises an inner portion 21 for engagement within the neck 12.
  • This inner portion 21 has an outer surface 22 which is of opposite taper to the surface 16 and is sealingly engaged therewith.
  • a bore 23 extends from the surface 22 upwardly through the closure member 13 to a delivery point in the form of the brush holder 14.
  • the lower end 24 of the bore 23 is situated axially at a point where it may lie adjacent the channel 17. This is illustrated in Figure 1. It is, however, spaced axially from the lower end of the inner portion 21 of the closure member 13.
  • the lower surface of the inner portion 21 is adapted so as to be spaced adjacent the lower end of the tapered portion 1 6 but above the lower end of the channel 17.
  • the closure member 13 also includes an outer skirt portion 26 which extends downwardly below said portion 21 and surrounds the outer surface of the neck 12, the skirt portion 26 including a circumferential groove 27 adapted for engagement with the circumferential rib 18 on the outer surface of the neck to thereby retain the closure member 13 to prevent its removal.
  • the rib 18 and groove 27 are disposed axially below the lower end of the inner portion 21. If the closure member 13 and the container 10 are made of a flexible plastics material then the closure member 10 may be pressed on to the neck 12 and the flexibility of the material will allow the skirt portion 26 to ride over the circumferential rib 18 until the groove 27 and rib 18 inter-engage. It will be seen from Figure 1 that they are shaped to facilitate this but the shape of the groove 27 and rib 18 is such as to discourage or prevent the removal of the closure member 13.
  • the lower edge of the skirt 26 is castellated to provide two downwardly projecting stop members 28, 29 for engagement with the stop members 19, 20 as will be described with further reference to Figure 4.
  • the lower edge of the skirt portion 26 also includes an outwardly depending marker 31 and the adjacent upper surface of the container 10 carries the words OFF and ON spaced as shown in Figure 5.
  • the container 10 may be filled with a liquid such as a composition for cleaning dentures. It is desired to pass a controlled flow of fluid from the interior of container 10 to the base of the brush in the brush holder 14 through the bore 23. This is done by arranging the closure member 13 and neck 12 in the relative positions shown in Figure 1 which correspond to the relative positions shown in Figures 2 and 4. In this position the lower end of the bore 23 communicates with the channel 17. Fluid may pass from the interior of the container 10 (when turned upside down or squeezed) into the channel 17 where its flow is controlled as the channel 17 is of small cross section (i.e.
  • the closure member 13 may be rotated through 90° relative to the neck 12 to the position shown in Figure 3 (and Figure 5) at which point the lower end of the bore 23 will not be in communication with the channel 17.
  • liquid may only pass into the channel 17 but cannot pass from there to the bore 23 and is prevented from passing further upwards than the channel 17 by the sealing engagement between the upper portion of the tapered surface 16 and corresponding surface of the inner portion 21 of the closure member 13. In this position, therefore, the container is sealingly closed and fluid cannot pass from the interior to the exterior.
  • the provision of the tapered surface 16 allows for the channel 17 to be accurately moulded which allows for accurate flow control of the fluid passing through the channel and also allows for a fine surface to be moulded on the portion 16 and abutting portion 22 whereby they may sealingly engage with one another.
  • the number of components which require to be moulded is two, that is the container 10 and the closure member 13, whereas, for example, in our copending British earlier patent application 26013/78 three separate parts are required.
  • a further advantage is that in use, the brush which extends out of the brush holder portion 14 is at an angle which facilitates cleaning of false teeth with the brush.
  • the container which is general elliptical in horizontal section and the closure member 13 are arranged so that in the open position whereby the lower end of the bore 23 communicates with the channel 17, the angled brush holder portion 14 lies generally along the major axis of the elliptical cross section (when seen in plan view in Figure 7). When closed the brush holder portion lies generally at right angles thereto.
  • the second embodiment of the invention incorporates all of the advantages of the first embodiment of the invention and in particular that the neck portion of the container has an outwardly tapering inside surface portion with a channel being provided in the outwardly tapering inside surface portion.
  • the neck 12 may form part of a tube rather than the bottle shaped container 10.
  • Means may also be provided for retaining the brush holder in the open and closed positions. This may be provided by a moulded stud on the neck or brush holder and a cooperating depression on the brush holder or neck respectively.
