  • The, or each, stop member may be in the form of an elongate member which may have a proximal end region at which the, or each, stop member is attached to the valve member, and a distal end region to engage an engagement member when the valve member reaches its open condition.
  • the engagement member may be provided on the main body.
  • the engagement member may be a shoulder extending inwardly from the main body.
  • the shoulder may extend in an annular configuration around the main body.
  • the engagement member may constitute the reaction means.
  • the valve arrangement includes three of said spring members which may be substantially equispaced around the valve member.
  • the valve member may include three of said stop members which may be substantially equispaced around the valve member.
  • the valve member may be of a generally conical configuration.
  • the spring members and the stop means extend from the base thereof.
  • the apex of the valve member is preferably received in an aperture defined by the valve seat.
  • the apex extends through said aperture to engage an opening member which can apply a force thereto to open the valve member.
  • the valve member may be provided with plunger means, whereby a force applied to said plunger means may move the valve member to said open condition.
  • the plunger means comprises a projection preferably extending outwardly of the valve arrangement.
  • the resilient urging means includes four of said spring members which are preferably substantially evenly spaced around the valve member.
  • the valve arrangement is preferably formed of a resilient plastics material, for example acetal.
  • the device 10 also includes a flange 16 to enable the device 10 to be mounted to a container which will contain a liquid to be dispersed.
  • An annular valve seat member 17 is provided in the main body 11.
  • the first portion 12 extends from the valve seat member 17 in a first direction.
  • the device 10 also includes a second portion 18 extending from the valve seat member 17 in a second direction, opposite to the first direction.
  • the first and second portions 12 and 18 are in the form of substantially cylindrical tubes.
  • the second portion 18 is provided with annular projections 18A extending outwardly therefrom.
  • the flange 16 is provided on the second portion 18 between the projections 18A and the valve seat member 17.
  • the valve seat member 17 defines a central aperture 17A through which fluid can pass.
  • the container In order to mount the device 10 to the container, the container is provided with an outlet spout (not shown) in the form of a tube.
  • the outlet spout is of an appropriate shape and size to receive therein the second portion 18 of the device 10 such that the projections 18A engage the side wall of the outlet spout and are an interference fit therewith, thereby sealing the device 10 to the outlet spout.
  • the flange 16 can be used to connect the device 10 to the container, for example by ultrasonic welding or heat sealing.
  • the second portion 18 holds within it a valve arrangement 19 which comprises resilient urging means 20, and a valve member 22.
  • the resilient urging means 20 and the valve member 22 are formed of a plastics material, integrally with each other.
  • the valve member 22 is movable between a closed condition (as shown in solid lines) in which the valve member is in engagement with a valve seat 23 on the valve seat member 17, and an open condition (as shown in dashed lines) in which the valve member 22 disengaged from the valve seat 23.
  • the valve seat 23 surrounds and defines the central aperture 17A.
  • a fluid pathway 24 is defined through the main body 11 from a first end region 26 to a second end region 28.
  • the passage 24 passes through the aperture 17A at the valve seat 23 in the region between the first and second portions 12, 18.
  • the resilient urging means 20 acts to urge the valve member 22 into the closed condition in engagement with the valve seat 23 to prevent the flow of fluid through the aperture 17A.
  • the resilient urging means 20 comprises four spring members in the form of leaf springs 32 (only three of which are shown) extending from the valve member 22 to a reaction member 34.
  • the resilient means 20 may be provided with a different number of spring members, for example 3, 5 or 6.
  • the reaction member 34 is substantially circular in configuration, conforming to the size and shape of the inner cross-section of the second portion 18.
  • the reaction member 34 defines an opening corresponding to the opening in the second portion 18 at the first end region 26 to allow fluid to flow therethrough.
  • the valve member 22 defines sloping sides 36 to engage correspondingly sloping sides of the valve seat 23.
  • a push member 38 extends from the valve member 22 into the first portion 12.
  • the push member 38 is adapted to engage an appropriate formation on the corresponding device on the delivery line as it is screwed onto the threads 14, whereby the push member 38 is pushed inwardly of the section 18 and, correspondingly, the valve member 22 is moved towards the open condition, as indicated in dotted lines. This movement of the valve member 22 to the open condition deforms the leaf springs 32 to their deformed condition, as also shown in dotted lines.
  • valve arrangement 19 is of a unitary construction, with the valve member 22 being integral with the spring means 20. It is preferred that the valve arrangement 19 is formed by a suitable process, by example moulding, preferably from a suitably resilient plastics material, for example acetal.
  • FIGs. 4 to 6 of the drawings there is shown another embodiment which comprises many of the same features as shown in Figs. 1 to 3, and these have been designated with the same reference numeral.
  • valve arrangement 19 is replaced by a valve arrangement 119 formed of a resilient plastics material, for example acetal and comprises a generally conical valve member 120, the apex 122 of which is rounded, or made generally planar.
  • the valve arrangement 119 also includes resilient urging means 124 which comprises a plurality of spring members in the form of leaf springs 126.
  • the resilient urging means 124 comprises spring members in the form of three leaf springs 126 which extend from the base of the conical valve member 120 and engage the outermost end region of the second portion 18 of the main body 11.
  • An annular shoulder or flange 128 extends inwardly from the wall of the second portion 18 to provide a reaction for each leaf spring 126.
  • each of the stop members 136 engages the annular flange 128 to prevent further opening of the valve member 120. In this condition, fluid can flow along the pathway 24 through the aperture 17A.
  • the delivery line is disconnected from the first portion 14 of the connector 10 and allows the leaf springs 126 to urge the valve member into its closed condition in engagement with the valve seat 23.
