11 Claims. 1

This invention relates to new and useful improvements in measuring or dispensing devices for liquid containers and has particular relation to a device for dispensing a. measured amount of the contents of a container.

An object of the invention is to provide a convenient and inexpensive device for use in dispensing measured doses or quantities from an inverted bottle or container.

Another object is to provide a liquid dispenser comprising an inverted container, a combined valve'and stop in the neck of the container, a cap adapted to be used to cover said valve and to be used as a measuring cup and including a portion adapted to engage and unseat the valve and which portion is below the open end of the cap whereby on the filling of the cap to the location of said portion the liquid within the cap will seal oil the discharge end of the valve, preventing the entrance of air to the receptacle and thereby stopping the flow from the latter.

Other objects and advantages of the invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. However, it is to be understood that the invention is not limited to the details disclosed but includes all such variations and r'nodifications as fall within the spirit of the invention and the scope of the appended claims.

In the drawing:

Fig. 1 is a perspective View showing the dispenser of the invention fully closed and mounted as on a wall or the like; I

Fig. 2 is a vertical sectional view through the lower end portion of the dispenser as viewed in Fig. 1;

Fig. 3 is a View similar to Fig. 2 but illustrating the manner of use; and u Fig. 4 is a perspective View s of the valve employed.

Referring in detail to the drawing, the liquid dispenser of the invention is shown as comprising a bottle or other container, generally designated [0. In Fig. 1, bottle or container I is shown as held in inverted position by means of a spring clip ,H which is in turn secured against a. portion of the wall or the like I2 by means of screws I3. Container It includes a neck portion l4 immediately inwardly of which is a thickened portion is externally screw threaded as shown.

About the-base of the thickened portion I5 is a compressible gasket or washer l6. Slidable. in the neck portion I4 is a valve, generally desigvalve I 1 and such passageway includes a cross portion 20 and a longitudinal portion 2|. Cross portion 20 opens through opposite sides of the stem [8 while the longitudinal passage 2| opens through the lower side of the head or flange I 9.

As will later more fully appear, the stem portion l8 of the valve has a sliding fit in the neck M of the container. When the valve is in its lowermost position, as in Fig. 2, the ends of the passage portion 20 are closed by engagement with the interior of the container neck l4 so that the contents of the container may not enter into the valve. This is the normal position of the valve and it is urged to such position and resiliently retained in such @position by a small coil spring 22. This spring is anchored in place by the partial reception of one of its coils in a groove 23 in the container neck HIV and the partial reception of a second coil in a hole or groove 24 in the stem portion of the valve [1.

Fitting over the valve'and the neck portion l4 and completely enclosing these parts is a cap or cup 25. Such cap or cup is internally screw threaded at its upper or open end, as at 26, and inwardly of said threads and of its upper or open end is provided with an annular shoulder 21. When the cup 25 is in container closing position, as in Figs. 1 and 2, its threads 26 are engaged with those on the thickened portion 15 of the container and the cap is threaded home so that its free open end engages the compressible gasket l6 whereby a sealis established between the cap and the container.

When some of the contents of the container are desired, cap 25 is unscrewed from its position on the container. Then by moving the cap somewhat laterally, as suggested in Fig. 3, a portion of annular shoulder 21 of the cap is engaged with the underside of an edge portion of the annular head or flange'lfl. Now on the cap being shifted upwardly the valve I! is moved inwardly with respect to the bottle neck exposing the ends of the cross passage 20, (of the T-shaped passage) to the interior of the container.

At this time the contents of the container may flow into said T-sh'aped passage entering through either or both ends of the cross passage and being discharged through the lowerend of the longitudinal passage}! into the cup 25. When the height of liquid in the cup 25 reaches the under or lower side ofthehead or flange I9 the further entrance of air into the container I is prevented,

a li'u id seal being established.

Thus there will be no further movement of liquid from the container l 0 into the cap or cup 25 and a measured amount of such contents will be in the cap 25. On removal of the cap from the position of Fig. 3 the spring 22 expands and shifts the valve downwardly, as the pressure of the cap on the valve is released, moving the valve back to the closed position of Fig. 2.

The container l0 may be of any desired material as may the valve I! and the cap 25. Preferably the valve and cap are of a plastic material while the container would be of glass, but this is not essential and the invention is not limited to the use of such materials. With the described construction it will be clear that the cup 25 may be readily filled to a predetermined extent so that a predetermined amount of liquid will be dispensed into the cup. This will be accomplished without any visual observation, and, in fact, the measured amount of the contents of the bottle or container may be obtained in the dark and without the benefit of visual observation.

The position of the shoulder 27 and its engagement with the radial head or flange portion I9 determines the extent to which the cup 25 will be filled as when the height of liquid in the cup seals off the lower end of the T-shaped passage in the valve further flow of liouid from the container does not occur. The s ring 22, in addition to constantly urging the valve into the closed position of Fig. 2, actually limits movement of the valve and su ports the same against falling out of the neck of the bottle.

From the above it will be seen that the dispensing device .of the invention is of simple and inexpensive construction. The invention comprises essentially the combination of the detachable can or cup .25 together with the valve I1, the use of these two parts as described involving the ap lication of the principle that the liouid will rise in the cup only until the mouth of the valve is sealed against the further entrance of air into the container.

Fromthe drawing it will be clear that the shoul- .der 2! is so located within the cup or cap that the liquid ma rise in the latter to cover the actual end of the bottle neck and yet there will be no oyerfiow. This would'beof im ortance with a different con truction of valve and so the in-' vention com rehends the location of s oulder 21 in such relation to the open end of the cup or cap that, without overflowin the latter may be filled to a point where its contents seal off the discharge end of the container neck. In effect such is the case in the embodiment shown as the tubular valve portion I8 is an extension of the container neck.

Having thus set forth the nature of my invention, what I claim is:
