Abstract
Abstract:
The present invention relates to a valve, especially those intended for use in pressurised fluid containers.
The valve is formed by a body which is fitted on one side of a dish. A movable member has a duct which passes through the dish, affording a leak-tight seal relative to a pressurised fluid. The movable member emerges on the outside on the side opposite the body and is mounted so that it may be displaced by a first type of motion, counter to the return force of a spring, from a position in which a duct does not communicate with the inside of the body to a position in which it opens into the inside of the body. The improvement being that the member is mounted so that it may be displaced by a second type of motion and is provided with a first unit cooperating with a second unit. The first and second units only allow the first type of motion for a prescribed relative position of these first and second units which position is reached by the second type of motion. The second type of motion is also opposed by the spring.

Description
S~72~
..
This invention relates to valves, especially those intended for use in pressurised fluid containers, such as aerosol cans.
The valve according to -the invention incorporates a safety mechanism which pre~ents accidental operation, for example if the valve is manipulated by a young child, but does not use any more components than a conventional valve and does not even use a different type of component from those conventionally used in a valve. It is also very simple to assemble, whilst providing a tight seal. It is easily operated by anyone who knows the /0 procedure required.
The valve is formed by a body, preferably a body of-revolution;
a member through which an outlet duct passes, said duct opening out towards the outside, possibly via a spray means, is displaced by a first type of motion, notably translationa- motion along the axis of the body which corresponds to that of the neck of the container. This displacement takes place, counter to the force of a spring, from a position in which the duct does not communicate with the interior of the body to a position in which the duct opens into the latter.
~0 Accordiny to the invention, the member is displaced in the body by a second type o~ motion, notably rotational motion about the axis common to the body and the member. The body and the member are provided with cooperating means, for example a recess on one and a projection on the other or vice versa, so that the first type of movement is only possible for a prescribed relative position of these means, which is reached by the second type of movement which the spring also tends to counteract. Thus, the-helical spring is under both compressive and torsional stress.
-.
'7;~
In order to actuate the valve, the user must first rotate the member relative to the body counter to the spring and when it has reached a certain rotational position which is not automatically maintained but is only maintained by the deli~erate operation by the user, the member can and should now be pushed, so as to compress the spring, thus moving into the operating position which again is not automatically maintained, since the spring returns to its initial position as soon as the user stops actuating it~
.ID It will be appreciated that this constitutes a quite remarkable automatic safety feature.
If the ends of the helical spring are in the form of arches r especially located in two different planes, preferably perpendicular, when the sp~ing is not under stress, it is easy to engage one of the arches in a blind slot in the member and to provide a slot for receiving the other arch at the bottom of the b~dy. Then the valve is assembled simply by successively engaging the constituent components in the body. The valve can be moun~ed on the container, without the addition of any external components, on existing assembly lines.
The second type of motion, especially the path o~ rotation of the member in the body, can be limited by conventional means, for example by providing an external rib on the member which comes to abut on the side wall of an associated recess provided in the body.
The member may be integral with a spray or push button with a channel provided on the free opposite surface to facilitate actuation by the user's finger. This free sur~ace may also comprise, laterally of the channel and hence in an eccentric ~5a~7~ .
position, an operating catch or depression enab~ing the member to be rotated by using the push button as a crank, The invention is explained with reference ~o the examples shown in the drawings, wherein:
Figures 1 to 3 are sectional views in a plane passing through the axis of a valve according to the invention in the closed, intermediate and open positions.
Figure 4 is a perspective view, partially cut away, of the member of the valve.
l~ Figure 5 is a perspective view, partially c~t away, of the body of the valve.
Figure 6 is a perspective view of the push button of the valve, and Figure 7 shows an alternative embodiment of the means for limiting the second type of motion.
The valve comprises a body 1 fitted by means of a joint 2 on a dish 3. The hollow body has an axis of re~olution XX~ and is extended at one end by a tubular appendage 4 which opens into the bottom of a chamber 5 inside the body, the bottom of said ao c~amber 5 being provided with a slot 5a and said chamber being defined by the lower side wall 6 of the body. The wall 6 has a sh~ulder 7 halfway up it and extends as far as the joint 2, thus defining an upper chamber 27. An inwardly ~irected projection 8 is provided on the shoulder 7.
~ reely engaging in the upper chamber is a movable member 9 made up of a cylindrical skirt 10, the edge 11 of which abuts on the projection 8 unless the latter is locatea opposite an indentation 12 opening towards the chamber 5 and provided in the edge 1-1. The skirt 10 is continued by a frustum-shaped portion 13 ~L~s~
converging towards the j~int 2, then by a cylindrical rod 14 passing through the joint 2 and having a duct 15 passing through it, said duct 15 having an outlet 16 towards the outside and a lateral inlet 17 opposite the joint 2, but coming inside the body when the projection 8 engages in the indentation 12.
In the centre of the portion 13, a blind slot 17a, opening towards the chamber 5, is provided.
A helical spring 18 engages with one of its end arches 19 in the slot 5a, whilst the other arch 20 engages in the slot l 17a.
An external rib 21 is provided in the side wall of the member 9, whilst the body 1 comprises, opposite this rib 21, a recess 22 which extends over an arc of a circle having an angle of 45 at the centre.
The rod 14 is surmounted by a spray 23 with a push ~utton, with which it is integral by the engagement of a catch 28 and indentation 29, the free surface 24 of the spray having a groove 25 for accommodating the user's finger D and, in an eccentric position relative to the axis XX' and adjacent to the ao groove 25, a catch 26, Preferably, the rod 14 is corrugated so that each rib can act as a catch, thus making assembly easier.
In the closed position (Figure 1), the planes of the arches 19 an~ 20 are perpendicular.
In order to operate the valve, which brings the appendage 4 into communication with a container, the member 9 has to be rotated by actuating the catch 26 with the rib 21 describing the recess 22, thus imparting torsion to the spring 18, until the indentation 12 is located opposite the projection 8 (Fig. 2);
the member 9, now able to move down into the body 1, must then be pressed down so as to bring the inlet 17 into communication with the interior of the body 1 (Figure 3) and permit vapori-sation of the liquid which is contained therein and which reaches it through the appendage 4, the duct 15 and the outlet 16. The catch may also be replaced by a recess for the finger provided in the spray and opening out on the side opposite the spray nozzle.
As soon as the user releases his finger, at whatever moment, the return effect of the spring 18 occurs.
The spring 18 and the constituents parts of the valve are assembled by stacking them in the body 1.
According to Figure 7, the second type of motion is limited on the lower surface of the movable member 9 by the provision, to one side of the existing indentation 12, of a second indentation 30 which is lower than the first.
This simplifies the moulding of the movable member and the assembly of the valve.
