Description
SPECIFICATION
Valve for dispensing a liquid from a container
The invention relates to a valve for dispensing a liquid from a container in particular for a valve-type applicator.
It is known to provide a valve-type applicator with a valve having a valve pin which projects from the dispensing orifice and has a conical portion, the conical portion being held by means of a spring against a corresponding conical surface of the dispensing orifice.
A valve of this type is known for a valvetype applicator which consists of an elongate container for a treatment liquid and of an applicator sponge attached to the front end in the region of the valve pin. In the state of rest, the valve is held closed by means of spring pressure. When the coating surface of the sponge is pressed perpendicularly against a treatment surface, the valve pin, which is essentially perpendicular to the treatment surface, is pushed back counter to the spring pressure and the dispensing orifice is exposed, so that treatment liquid can impregnate the sponge. At the same time, the valve pin is guided in a bore which is adjacent to the conical portion and which has a longitudinal dimension corresponding to the diameter of the valve pin or even longer than this.Because the valve pin is guided in this way, it can only be displaced in its axiai direction by pressing the applicator sponge down perpendicularly. However, the treatment liquid to be applied has to be spread and distributed by means of the applicator sponge over the surface to be treated. Since the liquid stored in the applicator sponge is used up relatively quickly, the valve has to be actuated repeatedly during the coating operation by pressing the down perpendicularly, so that there is a sufficient supply of liquid in the sponge. This is troublesome and interferes with the work carried out by the valve-type applicator.
The object on which the invention is based is to design a valve of the type indicated in the introduction, in such a way that it becomes possible to supply liquid from the container to the applicator tool even during the coating movement of the applicator tool.
According to one aspect of the invention there is provided a valve for dispensing a liquid from a container, the valve including a valve pin which projects from a dispensing orifice, the pin having a conical portion which is resiliently urged into seating contact with a corresponding conical surface of the dispensing orifice, an applicator tool arranged round the dispensing orifice or the valve pin, the longitudinal dimension of the dispensing orifice corresponding essentially to that of the conical portion of the pin. Accordingly there is therefore no need for a bore guiding the valve pin along its axis, so that the valve pin can be tilted during a coating movement with the valve-type applicator, the conical portion partially lifting off from the correspondingly conical sealing surface, so that liquid can continue to flow even during the coating movement of the applicator tool.
According to another aspect of the invention there is provided a valve for dispensing a liquid from a container, the valve including a valve pin which projects from a dispensing orifice, the pin having a conical portion which is resiliently urged into seating contact with a correspondingly conical surface of the dispensing orifice, the dispensing orifice and valve pin being adapted to enable the valve pin to tilt relative to the orifice whilst said conical portion is seated on the conical surface.
Various aspects of the invention are hereinafter described with reference to the accompanying drawings, in which:
Figure 1 shows a sectional representation of a known valve; and
Figure 2 is a similar view to Fig. 1 showing an embodiment according to the present invention.
In the Figures, 1 denotes a circular valve plate with a hollow-cylindrical extension 2, by means of which the valve plate is pressed into a bore of an elongate container, indicated diagrammatically at 3, which contains a treatment liquid. Supported on a step or an annular shoulder on the inner periphery of the hollowcylindrical extension 2 is a frusto-conically coiled spring 4, the opposite end of which rests against a conical portion 5 of a valve pin 6.
The valve pin 6 can consist of plastic, with the spring 4 of the same plastic material being moulded on.
In the known embodiment according to Fig.
1, the valve pin 6 is relatively short and is guided in a bore 7 in the valve plate 1, the longitudinal dimension of the bore 7 corresponding at least to the diameter of the valve pin 6. Adjacent to the bore 7 is a conical sealing surface 8, against which the conical portion 5 of the valve pin 6 is pressed by means of the spring 4. The longitudinal dimension of the cylindrical portion of the valve pin 6 corresponds approximately to three times the diameter.
In this known embodiment, it is possible to open the valve only by pressing the valve pin 6 down perpendicularly on to a treatment surface parallel to the valve plate 1, so that liquid can flow out of the container 3 into an applicator sponge 9 surrounding the valve pin 6 and fastened to the valve plate 1 by means of gluing.
In the design according to the invention, as shown in Fig. 2, there is no longitudinal guidance of the valve pin 6. The dispensing orifice is formed merely by the conical sealing surface 8, against which the conical portion 5 of the valve pin 6 lies in the state of rest. The cylindrical portion of the valve pin 6 is extended in length. For example, its longitudinal dimension corresponds approximately to four to five times the diameter.
During a coating movement approximately parallel to the applicator surface, the valve pin 6 is tilted somewhat, so that the conical portion 5 partially lifts off from the conical sealing surface 8, with the result that treatment liquid can flow into the applicator sponge 9, without the need for a perpendicular pressing movement. Controlled opening of the valve is possible according to the pressing force exerted during the coating movement. It is still guaranteed that the valve is leak-proof in the state of rest.
The valve according to Fig. 2 is particularly suitable for a valve-type applicator with an applicator brush which is indicated by broken lines at 10 in Fig. 2. The bristles project somewhat beyond the valve pin 6. During the coating movement, the valve pin is tilted by the sloping bristles, so that liquid can flow out. The bristles should be arranged so close together- that there is no possibility that the valve pin, which has a rounded front end, will scratch the surface to be treated.
The valve preferably consists of polyethylene. However, another blowable and injectionmouldable plastics can also be used.
In the embodiment according to the invention, shown in Fig. 2, the conical sealing portion 8 has, at the narrowest point, a diameter which is greater than the diameter of the cylindrical portion of the valve pin 6, so that the latter can easily be tilted.
