Accordingly, spout blockage may be performed by the moveable valve member 14 ( Figure 3A) which is capable of selectively creating a blockage in the spout 6 and preventing fluid flow.
  • the valve 11 allows fluid flow through the spout 6 when a fluid container is substantially vertical and the opening to the container uppermost, however, it is also envisaged that in instances of forceful fluid flow through the spout 6, movement of the item 14 to a blocking position 12 may occur. Therefore, it is envisaged that in order to allow fluid to be supplied from a fluid container, via the spout 6 to the reservoir 3, a controlled and more gentle fluid flow is required (to enable the valve 11 to operate in an open flow arrangement position such as at 13).
  • a controlled and more gentle fluid flow is required (to enable the valve 11 to operate in an open flow arrangement position such as at 13).

  • This mode of operation may be desirable as it is generally at angles other than substantially vertical at which a user will intend to position the dispenser unit 1 (and reservoir) to discharge any reservoir contents. Such angles that induce valve member 14 movement other than at substantially vertical, thereby prevent additional fluid from travelling through the spout 6 and entering the reservoir 3 and subsequently discharging with an already measured volume of fluid (resulting in less accurate fluid dispensing). However, it is also generally recognised that these pre- determined angles may be angles greater than or substantially equal to 90°, relative to a vertical axis.

  • the moveable valve member 14 moves to block fluid flow when at position 12; but allow fluid flow through the spout 6 into the reservoir 3 when at any other position. Further, moveable valve member 14 may locate itself at position 15 out of the path of fluid flow path 16 when fluid is promoted to flow up through the spout 6.
  • the predetermined angles are angles that encourage the moveable valve member 14 to move, sometimes under gravity, and sometimes due to fluid flows forcing the moveable item; to location 12.
  • the valve member 14 may be of any suitable shape and/or configuration to allow the valve to operate substantially as described above; however it should be noted that it may preferably be made or constructed of materials which are denser than the fluid within which they may operate, such as metallic materials. For example, this may be a useful criteria as an item of less dense construction that the fluid it operates in, may have a tendency to float in the fluid, and subsequently rise to a blocking position 12. This may have detrimental or inhibiting effects on the operation of the valve 11.
  • the valve member 14 may be configured as shown in Figures 2-3C, so that its tip 28 is able to plug or block the spout; and the base 29 is of a diameter less than the spout diameter, but one or more wings 30 are located about the valve member 14 to ensure that the base 29 does not block the spout.
