IIEASURING DISPEH-SING CA? Filed March 18, 1933 www5 Patented Sept. 4, 1934 UNITED STATES PATENT OFFICE 4 Claims.

My invention relates to measuring and dispensing device for containers whereby a measured amount of material may be removed from the container. My invention is applicable not only to the measuring of liquids but also to the measurement of powdered and granulated materials and the like.

It is the principal purpose of this invention to provide a device of this character in which the measuring chamber is provided with a. movable wall under the control of the operator so that the size of the measuring chamber is readily adjusted to the desired quantity to be dispensed.

More particularly it is a purpose of my invention to provide a measuring and dispensing closure for bottles and the like which closure is provided with a partition or stopper member insertible into the outlet neck and a closure portion- ;for closing the outlet rA thus providing a; chamber between the partition member and the closure which chamber may be varied by moving the partition member in or out with respect to the closure member together with means for alternately filling the chamber from Within the container and discharging the chamber contents through the closure.

Other and more specific objects and advantages of the invention will appear as the description proceeds in connection with the accompanying drawing wherein the preferred form of the invention is shown. It is to be understood however that the drawing and description are illustrative only and are not to be taken as limiting invention except in so far as it is limited by the prior art and the appended claims.

In.the drawing:

Fig. 1 is the section longitudinal through the neck of a bottle equipped with my invention;

Fig. 2 is a. top plan view of the device shown in Fig. 1; y

Fig. 3 is a side View partly in section of a modied form of cap; and

Fig. 4 is a side view partly in section of a modied form of the invention as applied to a large container.

Referring now in detail to the drawing I show at 5 a bottle having the neck portion 6 which is screw threaded at the top as indicated at 7 to receive the cap 8. It is obvious of course that this manner of securing a cap on a bottle is conventional and the cap may of course be secured in any other suitable manner. This cap has the lip 9 thereon for pouring the contents of the bottle and also has the outlet opening at 10 which may be of any suitable size. A valve 11 is pivoted in the cap 8 and is cut out as indicated at 12 so that in the position shown in Fig. 1, the cut out portion 12 and the outlet opening 10 register to permit the contents in the neck of the bottle to be discharged. This valve member 11 is normally held by means of the spring 13 in a position to close the opening 10 but may be moved by the hand piece 14 into the position shown in Fig. 1.

With the neck 6 I provide a. partition member l5 which is carried by the hollow shaft 16 that projects through the valve 1l and has a rather tight fit therewith. The partition member 15 can be adjusted lengthwise. of the neck 6 by sliding the shaft 16 in the Valve member 11 endwise with respect to the cap. In this way the member 15 can be positioned at the line 4 as shown in Fig. 1 or moved up to any one of the

lines

1, 2 or 3 as desired.

Member 15 is preferably constructed of rubber or other suitable substance not affected by the materials to be dispensed from the bottle and is so constructed as to have a substantial frictional engagement of the bottle neck. This member 15 is provided with suitable openings such as 17 and 18 and these openings are normally closed by the valve 19. Valvev 19 is mounted on the stem 20 which passes up through the shaft 16 and has the operating head 21 projecting from the upper end of the shaft. A spring 22 urges the valve 19 into closed position. This spring however is sufficiently weak that by applying pressure'to the member 21, valve 19 may be unseated readily in order to ll the chamber between the member 15 and the cap 8 by inverting the bottle. When this chamber is filled member 21 is released allowing valve 19 to close and then member 14 can be operated to uncover the opening 10 and allow the contents of the chamber to be dispensed.

In Figure 3 I have shown the cap 8' as provided With a tubular extension 23 instead of the spoon like portion 9 as such extensions are very useful in connection with giving medicines and dispensing other kinds of liquid.

In Figure 4 a large container 24 has the dispensing device 25 connected thereto through the valve 26. This dispensing device 25 consists of a container preferably made up of glass 27 closed by means of a cap 28 and 29, the cap 29 having the valve 26 connected thereto and having an outlet valve 30 at the bottom thereof.

The piston 31 is adjustable lengthwise in the cylinder 27 much in the same fashion as the partition member 1 5 is in Fig. l. The stem 32 is used in adjusting this piston.

Operation oi the device in Figure 4 is as iollows:

In inoperative position the piston 31 is shoved off the end piece 29. Now when a quantity piece oi' fluid is to be dispensed valve 26 is opened, valve 30 being closed and piston 31 is pulled back the desired amount to give the quantity to be dispensed. This draws the liquid into the chamber and valve 26 is then closed. Valve 30 is opened and piston 31 is shoved back against the end piece 29 thus adjusting all of the liquid after which the valve 30 may again be closed to leave the device ready for the next dispensing operation.

From the above description it is believed that the construction of this device will be clear to those skilled in this art. Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

l. A measuring and dispensing closure device for containers such as bottles and the like having a partition member insertible a variable distance in the container to isolate a portionof the space therein adjacent the outlet from the remainder of the space therein, a closure for the container outlet, valve means for said partition member to permit passage of the container contents therethrough, and valve means controlling discharge through said closure.

2. A measuring and dispensing closure device for containers such as bottles and the like comprising a closure member for the outlet from said container, said closure having a discharge opening therein, and a valve controlling said opening, a stem slidable through said closure member and having thereon and movable within the container, a partitionmember for separating a variable portion of the interior of said container adjacent the outlet from the remainder thereof to provide a measuring chamber, and valve means onsaid partition member for controlling flow of material into said chamber. A

3. A measuring and dispensing closure device for containers such as bottles and the like comprising a closure member for the outlet from said container, said closure having a discharge opening therein, and a valve controlling said opening, a stem slidable through said closure member and having thereon and movable within the container, a partition member for separating a variable portion of the interior-of said container adjacent the outlet from the remainder thereof to provide a measuring chamber, and valve means on said partition member for controlling ilow o1' material into said chamber, said valve means having an operating member projecting outwardly through said stem.

4. A measuring and dispensing closure device for containers such as bottles and the like comprising a closure member for the outlet from said. container, said closure having a discharge opening therein, and a valve controlling said opening, a stem slidable through said closure member and having thereon and movable within the container, a partition member for separating a variable portion of the interior of saidy container adjacent the outlet from the remainder thereof to provide a measuring chamber, and valve means on said partition member for controlling ow of material into said chamber, said valve means having an operating member projecting outwardly through said stem. said operating member being slidable endwise in said stem, and spring means holding said operating member in position to close the valve means.
