Abstract
A valve of the tilt opening type for pressurised dispensing containers comprises a mounting cup (211) having a cylindrical portion 212 and a frusto- conical portion 221. A valve stem extending through the valve cup has a surrounding sealing sleeve (215) which includes a frusto-conical skirt portion which surrounds the corresponding portion of the valve cup. The valve is opened by tilting the valve stem thereby unsealing apertures in the valve stem and the shape of the sealing sleeve prevents it lifting off from the mounting cup. <IMAGE>

SPECIFICATION
Improvements in valvesfor dispensers 5 The present invention relates to a va Ive for a pressurised dispensing container, the valve com pris ing a valve cup for securing to the container, a valve stem extending th rough an aperture in the valve cu p and having a valve head and a shoulder spaced from 10 the valve head, ports being provided in the valve stem adjacentthe valve head, and a resilient sealing sleeve surrounding the valve stem and being located be tween the valve head and the shoulder. Avalve such as this will hereinafter be referred to as---a valve of the 15 type defined---.
A problem that is encountered with a valve of the type defined isthat the sealing sleeve tends to move with the valve stem because it is gripped to the stem by the pack pressure. This has the effect of lifting the 20 sealing sleeve off the mounting cup creating a tendency forthe valve to leakratherthan open as intended.As a result known valvestend eitherto be verydifficuitto open, particularlyat high pressure, or 85 to open with a snap-action, which is undesirable.
25 it is known from British Patent Specification No.
1047792 to provide a tapered counterbore in the sealing sleeve of the valve in an attemptto facilitate the tilting action of the valve stem. It is also known to 90 provide a chamfered end to the sealing member 30 adjacentthe head of thevalve stem in an attemptto facilitate thetilting action of the valve stem further.
However, the problem of the sealing sleeve tending to lift off the mouting cup, causing the valve to leak, still 95 remains.
35 Accordingly, the present invention provides a valve of thetype defined in which the valve cup comprises a generally cylindrical portion and a frusto-conical portion, the aperture being provided in the smaller 100 end of thefrusto-conical portion, and the sealing 40 sleeve includes a frusto-conical skirt portion extend ing around said frusto-conical portion of the valve cup.
The sealing sleeve preferably has a counterbore surrounding the valve stem at its end adjacentthe valve head to facilitate tilting of the valve stem.
45 The sealing sleeve is preferably externally cham fered at its end adjacentthe valve head to facilitate tilting of the valve stem.
The sealing sleeve may include an integral, general- 110 ly 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 115 an integral gasket ring.
The invention also provides a pressurised dispensing container having a valve according to the invention.
By way of example, an embodiment of the present 120 invention, together with modifications thereto, will now be described with reference to the accompanying drawings, in which:- Figure 1 is a sectional view of a prior arttilt-opening valve, Figure 2 is a sectional view of an embodiment of a 65 valve according to the invention.
Figure 3 is a sectional view of a modified form of the valve of Figure 2, and Figure 4 is a sectional view of a further modified form of the valve of Figure 2.
Atilt-opening valve 10 of a kind known to the art is shown in Figure 1. Thevalve 1 Oforms the end closure of a conventional pressurised dispensing container and is attachable thereto by crimping an annularcollar 11 which is incorporated into metal mounting cup 12 of the valve. There is a suitable gasket ring 13to ensure a fluid tightseal forthe container. A rigid valve stem 14 and an annular sealing sleeve 15 of rubberlike material extend through a central aperture in the mounting cup 12. The valve stem 14 has a flanged 80 head 16 at one end and an opposing shoulder 17 towardsthe other end. The valve stem 14 is open for dispensing fluid at its shouldered end and closed at the other end exceptfor a number of ports 18. The sealing sleeve 15 is located on the valve stem 14 between the head 16 and shoulder 17. 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 15to seal off fluid in the container. When the valve stem 17 istilted relative totheaxis 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.
A problem with tilt-opening valves arises in providing the valve with an easy, well-controlled tilting action for dispensing fluid whilst ensuring that an adequate seal is maintained. To this end, the 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. As a further aid, the same end of the sealing sleeve 15 incorporates an external chamfer 20. A problem still remains, however in thatthe sealing sleeve 15 will tend to move with the valve stem 14 when it is tilted, 105 particularly at high internal pressures. This will have the effect of lifting the sealing sleeve 15 off the mounting cup 12, creating a tendencyforthe valveto leak. Until now, therefore valves have tended to be eithervery difficuitto open, particularly at high pressures, or have opened with an undesirable snap-action.
Avalve 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).
In the valve 110 of Figure 2, 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 121 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 againstthe mounting cup 112, byvirtue of the f luid pressure, with a greater The drawing(s) originally filed was/were informal and the print here reproduced is taken from a later filed formal copy.
UB 2 126 282 A 2 force than before. This will reduce the tendency forthe sealing sleeve 115 to liftoff the mouting cup 112 when the valve stem 114 is tilted. Moreover, the additional frusto-conical portion 121 of the mounting cup 112 5 gives the valve 110 the ability to be able to withstand greater fluid pressures within the containerthan a conventional valve. This is because the frusto-conical shape is better able to withstand pressure than the traditional flat ended mounting cups.
It has the added advantage of making the valve 110 easierto install on a container because of the extra space availableforthe crimping tool.
The 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. In thevalve 210 of Figure 3, however, the skirt 222 of the sealing sleeve 215 extends beyond the frusto-conical portion 221 of 20 the mounting cup 222, right up to the gasket ring 213 in the annular collar 211. In this embodiment, the force tending to retain the sealing sleeve 215 against the mounting cup 212 will be even greaterthan in the Figure 2 embodiment. An important advantage of the 25 valve 210 shown in Figure 3 is that it is particularly convenientfor use with fluids which should not be allowed to come into contact with the mounting cup 212.
In thevalve 310 of Figure 4, the skirt 322 of the
