Definitions

  • the present invention relates to a valve for a pressurised dispensing container, the valve comprising a valve cup for securing to the container, a valve stem extending through an aperture in the valve cup and having a valve head and a shoulder spaced from the valve head, ports being provided in the valve stem adjacent the valve head, and a resilient sealing sleeve surrounding the valve stem and being located between the valve head and the shoulder.
  • a valve such as this will hereinafter be referred to as "a valve of the type defined”.
  • a problem that is encountered with a valve of the type defined is that the sealing sleeve tends to move with the valve stem because it is gripped to the stem by the pack pressure.
  • valves tend either to be very difficult to open, particularly at high pressure, or to open with a snap-action, which is undesirable.
  • the present invention provides a valve of the type defined in which the valve cup compris.es a generally cylindrical portion and a frusto-conical portion, the aperture being provided in the smaller end of the frusto-conical portion, and the sealing sleeve includes a frusto-conical skirt portion extending around said frusto-conical portion of the valve cup.
  • the sealing sleeve preferably has a counterbore surrounding the valve stem at its end adjacent the valve head to facilitate tilting of the valve stem.
  • the sealing sleeve is preferably externally chamfered at its end adjacent the valve head to facilitate tilting of the valve stem.
  • the sealing sleeve may include an integral, generally cylindrical skirt portion extending around said generally cylindrical portion of the valve cup.
  • the sealing sleeve may further include an integral, generally cylindrical skirt portion extending around said generally cylindrical portion of the valve cup and an integral gasket ring.
  • the invention also provides a pressurised dispensing container having a valve according to the invention.
  • a tilt-opening valve 10 of a kind known..to the art is shown in Figure 1.
  • the valve.10 forms the end closure of a conventional pressurised dispensing container and is attachable thereto by crimping an annular collar 11 which is incorporated into metal mounting cupl2 of the valve.
  • a rigid valve stem 14 and an annular sealing sleeve 15 of rubber-like material extend through a central aperture in the mounting cup 12.
  • the valve stem 14 has a flanged head 16 at one end and an opposing shoulder 17 towards the other end.
  • the valve stem 14 is open for dispensing fluid at its shouldered end and closed at the other end except for a number of ports 18.
  • the sealing sleeve 15 is located on the valve stem 14 between the head 16 and shoulder 17.
  • the valve stem 15 When the valve stem 15 is in its normal, axially-aligned position, as shown in Figure 1, the head 16 seats against the sealing sleeve 15 to seal off fluid in the container.
  • the valve stem 17 When the valve stem 17 is tilted relative to the axis of the container, one region of the head 16 lifts off its seat on the sealing sleeve 15 allowing fluid to flow under pressure through ports 18 to be dispensed out of the open end of the valve stem.
  • valve 10 known to the art and shown in Figure 1 incorporates a tapered counterbore 19 in the end of sealing sleeve 15 adjacent head 16 to facilitate tilting of the valve stem 14.
  • the same end of the sealing sleeve 15 incorporates an external chamfer 20.
  • a problem still remains, however, in that the sealing sleeve 15 will tend to move with the valve stem 14 when it is tilted, particularly at high internal pressures. This will have the effect of lifting the sealing sleeve 15 off the mounting cup 12, creating a tendency for the valve to leak.
  • valves have tended to be either very difficult to open, particularly at high pressures, or have opened with an undesirable snap-action.
  • a valve 110 according to the present invention is shown in Figure 2(one hundred has been added to the numberals which designate those features of the valve 110 corresponding with those known in the art.)
  • the mounting cup 112 is extended by an additional frusto-conical portion 121 at one end thereof, and the sealing sleeve 115 has a complementary frusto-conical skirt 112 which is designed to extend around the portion 1212 of the mounting. cup. Because of the additional surface area which the skirt 122 of the sealing sleeve 115 presents, the sealing sleeve will be held against the mounting cup 112, by virtue of the fluid pressure,with a greater force than before. This will reduce the tendency for the sealing sleeve 115 to lift off the mouting cup 112 when the valve stem 114 is tilted.
  • the additional frusto-conical portion 121 of the mounting cup 112 gives the valve 110 the ability to be able to withstand greater fluid pressures within the container than a conventional valve. This is because the frusto-conical shape is better able to withstand pressure than the traditional flat ended mounting cups.
  • valve 110 easier to install on a container because of the extra space available for the crimping tool.
  • valve 210 and 310 shown in Figures 3 and 4 respectively are in almost all respects identical with the valve 110 of figure 2, and like features have again been designated numerals increased by one hundred and two hundred respectively.
  • the skirt 222 of the sealing sleeve 215 extends beyond the frusto-conical portion 221 of the mounting cup 222, right up to the gasket ring 213 in the annular collar 211.
  • the force tending to retain the sealing sleeve 215 against the mounting cup 212 will be even greater than in the Figure 2 embodiment.
  • An important advantage of the valve 210 shown in Figure 3 is that it is particularly convenient for use with fluids which should not be allowed to come into contact with the mounting cup 212.
  • the skirt 322 of the sealing sleeve 315 conveniently incorporates the gasket ring 313 as an integral part.
  • the sealing sleeve in this embodiment it is not possible for the sealing sleeve in this embodiment to lift off the mounting cup and cause leaks.
