ACTUATING FITMENT FOR A SPRAY CONTAINER The following statement is a full description of this invention including the best method of performing it known to us:- 1A ACTUATING FITMNTr FOR A SPRAY CONTAINER The invention relates to an actuating f itment for a spray container which contains a product which is capable of flow and which is exposed to a gas pressure, and in a delivery duct a delivery valve which is actuable by the actuating fitment so that the product flows out through the delivery duct when the delivery valve is 'opened, wherein the actuating fitment has an axial bore which can be coupled to the delivery duct, a transverse bore leading from the axial bore to a discharge nozzle, and a regulating member which is snugly fitted in the axial bore and is axially displaceable, for through-flow regulation, with a throttlP bore.
In a known actuating fitmnent of that kind (EP 234 797 Bl), -the regulating member is in the form of a rubber disc which is pressed axially against an opening of the axial bore, which opening is coaxial with the throttle bore of the regulating membter, the rubber disc being deformed radially in dependence on the internal pressure in the spray container so that the through-flow cross-section of the throttle bore is reduced with increasing internal pressure. with decreasing internal pressure, the constriction of the bore is correspondingly less and thus *the through-flow cross-section is greater. As the through- flow is a function of the internal pressure and the through-flow cross-section, it remains substantially constant, independently of the internal pressure. However rubber-elastic material has the property that it swells when it coms into contact with certain fluids, for example grease-containing or oily fluids, as are frequently contained in spray cans of that kind. In addition, the nominal dimensions of rubberelastic components cannot be maintained with close tolerances in 2 manufacture, quite apart from the fact that they are dependent on temperature and alter in the course of time, due to ageing phenomena.
It would also be desirable to provide an actuating fitment of the general kind set forth, in which the through-flow rate, with the delivery valve open, is maintained with a higher degree of accuracy.
The present invention provides an actuating fitment adapted to be fitted onto a spray container which contains a product which is capable of flow and which is exposed to a gas pressure, and which has a delivery valve in a delivery duct which is actuable by the actuating fitment ~so that the product flows out through the delivery duct when the delivery valve is opened, wherein the actuating 15 fitment has an axial bore forming an inlet passage of the fitment which can be coupled to the delivery duct; a transverse bore leading from the axial bore to a discharge nozzle; and a regulating member which is snugly fitted in the axial bore and is axially displaceable, for 20 through-flow regulation; by means of a throttle bore; wherein the regnlating member is displaceable by the internal pressure of the spray container against a spring force of a spring bias means over an intake opening of the transverse bore until reaching an abutment provided in the '0 25 axial bore which stops the regulating member in a position in which it blocks a major part of the intake opening but not the whole of the opening; wherein the regulating member is made from substantially rigid material; and wherein the throttle bore is no larger than about 0.2mm 2 and is substantially smaller than the inlet passage so that it also serves to help maintain a constant through-flow by preventing a high rate of discharge therethrough upon actuation of the delivery valve.
2a Since the through-flow cross-section is kept very small, for example about 0.2 mm 2 in order to avoid unnecessary consumption of the product contained in the spray container, the through-flow rate is dependent to a considerable degree on the nominal dimensions of the regulating member being accurately maintained.
In that construction the regulating valve and the intake opening of the transverse bore form a through-flow regulating valve which keeps the through flow substantially constant, independently of the internal pressure. The throttle bore in the regulating valve also contributes, even if only to a slight degree, to keeping the through flow constant, because with a high internal pressure it affords a somewhat higher through-flow 15 resistance than at a lower internal pressure, so that that already ensures a certain degree of constancy of the through flow, which is independent of the internal pressure. Furthermore, the throttle bore already eliminates from the outset an excessively high rate of discharge, upon actuation of the delivery valve. As is S..already ooet moo i[ the case hitherto, there is no need of an additional housing for the through-flow regulating valve. The regulating member can be made from comparatively hard plastics material which is substantially resistant to ageing and which is insensitive in relation to the product contained in the spray container.
It is preferably provided that the intake opening of the transverse bore is formed as an axial slit, in the form of a rectangle.
That arrangement provides for linear dependency of the through-flow cross-section of the intake opening on the internal pressure, and thus provides for an even higher degree of constancy in the through flow.
The invention and developmnents thereof are described in greater detail hereinafter with reference to the drawing showing a preferred "embodiment, in which: Figure 1 is a view in axial section through an actuating fitment according to the invention, with a low internal pressure in the spray container, Figure 2 is a view in vertical section in a plane perpendicular to the sectional plane in Figure 1, Figure 3 shows the same sectional view as Figure 1, but at a Wm 20 internal pressure in the spray container, Figure 4 is a rear view of an insert of the actuating fitmnent, and Figure 5 is a section taken along line V-V in Figure 4.
.oe.oi The illustrated actuating fitment serves for the actuation of a delivery valve of a spray container (not shown) containing a product which is capable of flow and which is exposed to a gas pressure. The actuating fitment is approximately in the form of a cap with a coaxial inner tube 1 which delimits an axial bore 2. The tube I is fitted oa i-) a valve shank of the delivery valve, which shank forms a part of the delivery duct of the spray container, so that the tube is connected thereto by a friction locking effect. By depressing the valve shank by means of the actuating f itment, the delivery valve is opened in conventional maenner so that the product flows out through the delivery duct under the gas pressure obtaining in the spray container. In the vicinity of the upper end of the axial bore 2, a transverse bore 3 leads to a discharge nozzle 4. A regulating member 5 is snugly fitted in the axial bore 2 and is axially displaceable therein. It is in the form of a circular cylinder with a central transverse wall 6 in which there is a coaxial throttle bore 7. A coil, spring 8 is arranged between the transverse wall 6 and the upper end of the axial-bore 2 *which is in the form of a blind bore. The regulating member 5 is :6 :displaceable 'by the internal pressure in the spray container, against the force of the coil spring 8, over the intake opening 9 of the transverse bore 3, until encountering an abutment 10 which stops the regulating irreber 5 in a position in which it blocks the major part of the intake opening 9. The intake opening 9 of the transverse bore 3 is formed as an axial slit in the form of a rectangle (see Figure The **abutment 10 is divided into a plurality of radial and axial projections bysbtnalyVsae erruptions 11. From the intake opening 9, the trpansverse bore 3 enl arges in the form of flat surfaces which are apptoximately semi-elliptical in side vie,,, to a round cross-section.
The transverse bore 3 ccxmiunicates with an annular groove 12 in to which a substantially cap-shaped insert 13 is inserted with its 5 peripheral wall, in such a way that the latter bears sealingly against the radially outward wall of the annular groove 12 and is at a spacing relative to the radially inward wall, so that accordingly a further annular groove 14 remains free.
As Figures 4 and 5 mo~re clearly show, in the middle of its bottcm the insert 13 has a depression 15 which is initially of a circular-cylindrical configuration and which then tapers conically towards the nozzle 4. In addition, provided in the bottom of tho insert 13 are grooves 16 which converge substantially tangentially frcm the peripheral wall of the insert 13 to the central depression 15, the grooves being disposed at equal angular spacings.
A projection 17 which forms the radially inward 'wall of the annular groove 12 (see Figure 1) def ines on the one hand a swirl chamber together with the depression 15 in the insert 13 and on the other hand, together with the grooves 16, ducts which at their wider ends commnunicate with the annular groove 14.
The actuating fitment is then provided with stiffening ribs 18 between its peripheral wall and the tube 1.
:n order to open the delivery valve of the spray container, the *user presses with the finger against the slightly concave knurled :actuating surface of the actuating f itment. The product which is then urged out of the spray container by the ccmpressed gas flows through the axial bore 2, the throttle bore 7, the opening 9, the transverse bore 3, the annular groove 12, the annular groove 14, the grooves 16, :the depression 15 and the nozzle 4 to the exterior. In that situation it urges the regulating member 5 against the force of the coil spring 8 (upwardly) towards the intake opening 9. In that arrangement the coil spring 8 is of such a size that, when the spray container is full and .*Seat maximum internal pressure, the regulating member 5 is iindiately pressed to a position of bearing against the abutment 10, as shown in Figure 3. When the regulating member 5 is in that position, the product can nonetheless issue because the intake opening 9 is not ccompletely closed off by the regulating member 5. However the throttle bore 7, the small through-flow cross-section which still remiains in the opening 9 and finally the nozzle 4 which also acts as a throttle cause a corresponding throttling action in relation to the through flow.
That ensu_,s that an excessively large amount of product cannot be sprayed, in an undesirable fashion. Nonetheless substantially fine atomisation of the product is guaranteed, in particular due to swirling of the product in the depression 15 in the insert 13 with the propellent gas and the air.
If the internal pressure decreases due to repeated actuation of the spray container, the coil spring 8 presses the regulating member correspondingly further back against the internal pressure so that the free through-flow cross-section of the intake opening 9 is correspondingly increased and thus the through flow is still kept constant. In the position of the regulating member 5 shown in Figures 1 and 2, the container is substantially emptied and the internal pressure is accordingly very low, so that the regulating member completely opens the intake opening 9 and discharge of the remaining product is throttled only by the throttle bore 7 and the nozzle 4.
