6 Claims. 1

This invention relates to a liquid dispensing device and refers more particularly to a closure for containers, which is provided with a valve or faucet device automatically delivering uniform quantities of a liquid to receptacles of the same size.

An object of the present invention is the provision of a liquid dispensing device which may be conveniently mounted upon a cap or other closure of a container and which can be easily operated to dispense a certain amount of liquid.

Another object is the provision of a dispenser which may be used in bars, restaurants, laboratories and the like and which may be placed upon bottles or jars for automatically supplying the same amounts of liquid to glasses or other containers of uniform size.

Other objects of the present invention will become apparent from the following specification.

In accomplishing the objects of the present invention it was found desirable to provide a cap or similar closure member with an elongated outwardly extending tube serving as or carrying a guide for avalve rod projecting outwardly beyond the tube and connected with a spring loaded valve body adapted to interrupt the communication between the tube and the interior of the container carrying the closure member.

In operation, the valve rod is pressed against the bottom or a glass or other vessel into which the liquid is to be poured, thereby compressing the spring and raising the valve body from its seat upon the tube. If the container is placed upside down over the glass and if the closure member of the container is provided with an air vent, liquid will flow from the container and into the glass. Actual experiments which I have carried out, show that this flow of liquid will stop after the liquid has reached a certain level in the glass and that the amount of the dispensed liquid is the same whenever a glass of the same size is'used.

The invention will appear more clearly from the following detaiied description when taken in connection with the accompanying drawings showing, by way of example, preferred embodiments of the inventive idea.

In the drawings:

Figure 1 shows in side elevation a container the cap of which is provided with a dispensing device constructed is accordance with the principles of the present invention.

Figure 2 shows the dispensing device in longitudinal section, 'on an enlarged scale.

yond the support 25.

Figure 3 is a transverse section along the line 3-3 of Figure 2, on an enlarged scale.

Figure 4 illustrates the operation of the dispensing device.

Figure 5 shows in side elevation a container the cap of which is provided with a dispensing device of a somewhat difierent construction.

Figure 6 is a longitudinal section through the dispensing device shown in Figure 5.

Figure 7 illustrates the operation of the dispensing device shown in Figures 5 and 6.

The dispensing device shown in Figures 1 to 4 of the drawings is carried by a cap II] which is provided with screw threads II and which may be screwed upon the neck l2 of a bottle l3.

The cap !0 carries a tube I4 which is firmly connected with the cap or is integral therewith. The tube M extends on both sides of the cap I0 and its axis may coincide with the longitudinal axis of the bottle.

The tube It has a comparatively long portion which extends outwardly beyond the cap l0 and which is provided with two inner webs l5 and I6 constituting guides for a valve rod IT.

The web I5 is shown is detail in Figure 3 of the drawings and it includes a central sleeve .IB em-- bracing the rod l1 and connected to the tube M by web portions l9 and 20. Passages 2| and 22 on opposite sides of the web l5 connect.the interior 23 of the tube i l with the outside space. The web Iii which is situated further inside the tube H5, is of the same shape as the web I5.

That portion of the tube M which is situated within the bottle neck I2, is provided with outer screw threads 24 and has conical end surfaces constituting a valve seat 25.

A spring support 25 has a nut or sleeve 21 which is provided with inner screw threads and which is screwed upon the threaded end of the tube [4. A wall or web 28 connects the sleeve 21 with a p ate 29 the inner surface of which has an annular ridge 3!) enclosing one end of a coiled spring 3|. The spring 3| embraces the valve rod ll which extends through an opening provided in the plate 29.

The inner end of the valve rod 11 extend be- The outer end 32 of the valve rod I1 extends to a comparatively great distance beyond the outer end of the tube l4 and may have the form of a ball. A stop 33 is firmly mounted upon the valve red I?! between its end 32 and the web I5. As shown in Figures 1 and 2, the stop 33 is situated at a distance from the web 15 when a valve body 34 'is seated upon the valve seat 25. Figure 4 shows that the engag'eme'nt of the stop 33 with the web I5 limits the extent of the inward movement of the rod I1.

The valve body 34 is screwed upon a threaded portion of the rod I1 and is held firmly thereon by a nut 35 screwed upon the rod I1 and engaging the smaller end surface of the conical valve .body 34. The opposite surface of the valve body 3 1 has a recessed portion 38 (Fig. 2) receiving an end of the coiled spring 3 I.

The cap I is provided with a small opening 31 constituting the air vent. The cross-sections of the air vent 31, the liquid-transmitting tube I4 and the length of the rod I'I extending beyond the outer end of the liquid transmitting tube I4 being of such size relatively to each other that the entrance of air through the air vent 31' and hence the dispensing of liquid through the liquid transmitting tube I4 while the valve seat 25 is kept open, ceases when the dispensed liquid reaches a predetermined level relatively to the discharge end I of the tube I4.

When no external pressure is exerted upon the rod H, the valve body 34 is pressed against the seat by the spring 3i so that there is no communication between the interior 38 of the bottle I3 and the interior 23 of the tube I I.

In order to dispense a certain amount of liquid contained in the bottle I3, the bottle I3 is placed upside down over a glass 39 or any other vessel into which liquid is to be poured, and the end 32 of the rod l"! is pressed against the bottom 40 of the glass. This pressure causes the rod I I to move inwardly, thereby raising the valve body 34 oif the valve seat 25 and compressing the spring 3|, until the stop 33 strikes the web I5 of the tube I4.

The air vent opens at a point below the minimum level of the liquid in the supply container. Actual experiments which I have carried out show that the flow of liquid from the bottle I3 into the glass 39 will stop as soon as the liquid has reached a certain level in the glass 39 and that the amount of the dispensed liquid is the same whenever a glass 39 of the same size is used. This may be explained by the fact that the water column above the discharge end I5 of the tube 14 balances the water column within the tube I l and container I3 to such an extent that the friction which the air enterin through the vent 3? has to overcome, can no longer be overcome by the buoyancy of the entering air. Consequently, the vacuum built up over the liquid level in the container I3 by the discharge of liquid from the container is no longer equalized by the admission of new air through the air vent. Hence the outside liquid column will balance the inner liquid column. Thus the described dispensing device may be conveniently used in bars, restaurants, laboratories and similar establishments wherein the, same amounts of liquid are often dispensed into vessels of uniform size.

The amount of the dispensed liquid may be varied by varying the length of the projecting portion of the rod I! or the position of the valve body 34 upon the rod.

. The dispensing device illustrated in Figures 5 to 7 includes a tube mounted upon a cap 5i which is screwed upon the neck of a bottle 52.

Webs

53 and 54 constitute guides for a valve rod 55 carrying a valve body 55. A spring 5'! presses the valve body 56 against the inner end of the tube 55] and is engaged by a support 58 which is screwed upon the inner end of the tube 50. The inward movement of the rod 55 islimited by a stop 59.

The cap 5I carries an elastic sealing ring 60 which is interposed between the bottle neck and the cap, while another elastic sealin ring BI is situated between the cap 5I and the support 58.

In this construction, the air vent is constituted by an elbow tube or U-shaped tube 62 having a threaded end 53 which extends through the cap 5| and which is held in place by a nut 64 screwed upon the tube end 63.

This device operates in the same manner as the one previously described. The elbow pipe 52 is preferably situated outside of the glass 65 while the liquid is being poured, thereby facilitatin the dispensing of exact amounts of the liquid.

It is apparent that the specific illustration shown above has been given by way of illustration and not by way of limitation, and that the structures above described are subject to wide variation and modification without departing from the scope or intent of the invention; all of such variations and modifications are to be included within the scope of the present invention.
