i5 Claims.

This invention relates to liquid measuring or dispensing devices; and more particularly it relates to devices easily constructed and free from moving parts which dispense, a predetermined quantity oi liquid from a container when the containeris inverted. The new devices of the invention may be easily andeconomically produced, and are readily fastened to bottles or other containers as by means of screw threads p rovided on the neck friction joints, or by snap fastenings, or by'conl strueting the device,at"leastin part, integrally with the container, the container being provided with an enlarged or elongated neck if desiredor necessary.

The invention will be'described in detail in connection with the accompanying drawing, which illustrates in a somewhat diagrammatic fashiona dispensing device which embodies the invention, but the invention is not limited thereto.

In the drawing: h

Fig. l'is a sectional View oi the dispensing device attached to a bottle in an inverted position;

Fig. 2 is a sectional View of the same device in an upright position, showing the measured body of liquid ready to be discharged;

Fig. 3 is a sectional view of the same device in an inclined position' showing how the liquid flows out; and 1 Fig. 4 is a planfview of the device.

VIn the drawing, there is shown a bottle IU to which the dispensing device is attached.' The `dispensingdevice l2 as shown consists of a cylinder ld provided with internal threads I6 at the baseso it may befastened to the bottle and lwith the upper end i8 closed, except for the pouring spout il. Within this'shell is a longitudinal partition 20 extending from the top I8 about half way to the bottom, this partition serving to divide the upper interior of the device into two

compartments

22 and 24. f f

Above the threads I6 which permit the attach nient' of the device 4to a bottle or the like, there isY provided a seat 26, on Which'a diaphragm or plate 28 seats. This diaphragm is provided .with an opening 30 into' which fits the tube 32 (the tube 32 may ladvantageously be integral with the diapast the end of the partition 20.

phragm 28, as in the modication shown soithat the device as a whole consists of but two parts). The opening 30 and the tube 32 are offset from the center of the diaphragm, so that-when in place,v with themember 28 seated, the tube 32 extends into the compartment 24 a short distanceV y A g-Sket 34 of cork or other suitable material, with a properly located opening 3B, is cemented to the upper face of the diaphragm 28, to` provide a seal when the device is applied to a bottle or other container.

The operation of the device illustrated is very simple. Assuming' that the device has been kplaced upon a container or bottle containing ra liquid to beV dispensed in predetermined portions,` the bottle with the attached dispensing device is inverted, whereupon the liquid ilows through the tube 32 into thel compartment 24, the level of liquid rising in this vcompartment to a little above the end of the tube, but below Vthe 'end oithe partition 2D, a liquid seal thus beingy formed whichV prevents any greater'outflow of liquid. When thej bottle or container is then placed in an upright position, part of the liquidfrom the chamber24 flows back through the tube 32`and the remainder is retained in the dispensing device by the dia phragm or plate 28, as shown in Fig. 2. The relative amounts ofy liquid which will ow back into the bottle or container and which will be retained in the dispensing device will depend upon the relative area of the tubel 32 and the cross-sectional area of the compartment-24 surrounding it;

and these proportions can readily be adjustedso that with a given liquid capacity of the chamber 24 a predetermined arnountof the liquidwill remain in the dispensing device whenthe containery or bottle is placed in an upright position. I

When the container or bottle,.with the measured amount of liquid in the attached dispensing device, is then tilted as in Fig. 3 with the spout I7 down, the liquid retained in the dispensingr device will be poured from the spoutl Il.y Of

course, in this operation, care should be taken that the container is not tilted so suddenly as to throw some of the liquid to be dispensed into the compartment 24, and also that the `device is tilted suiiiciently'far so thatr the necessary liquid seal is formed. As the bottle or container is tilted and inverted to dispense the lmeasured amount of' liquid, thechamber 24 is again filled to the proper depth with liquid with the result that the dispensing device isr again charged with the proper amount of liquid, sothat each time a portion of the liquid is dispensed, another equal v portion is charged to the dispensing deii.

'I'he amount of liquid to be dispensed in each portion by one of these improved devices may be varied widely, as by varying the length of the tube 32, or the diameter of the cylinder Il or the 5 relative cross-sectional area of the tube 32 and the compartment 24, etc. For example, by providing the tube 32 with an inner sliding sleeve, the dispensing device may readily be made adjustable, so that it can be adjusted, Within reasonable limits, .to dispense various amounts of liquid in measured portions. Or the device may be made adjustable by positioning the seat 26 somewhat further in the shell H and providing removable rings seated thereon, so that the position of the diaphragm or plate 28 and thetube 32l may be varied with respect to the partition 20. However, it should be noted that in all cases it is essential that the tube 32 extend past the end of the partition so that necessaryliquid 20 seal is formed in the chamber 24. Also, it should be noted that it is essential that the partition 20 does not extend too far towards the bottom of the dispensing device, or some of the liquid to be dispensed will pass into the chamber 24 when 25 the container with the attached dispensing device is tilted.

A device adjusted for the dispensing of a liq uid in measured quantities of about 5 cc., having a construction such as illustrated in the drawing, may have about the following dimensions:

Inner diameter of cylinder i4, 1 inch.

Length of partition 20, 1% inches.

Distance from center line of cylinder to partition 20, 72 inch.

Overall length from tip of spout, 3 inches.

Overall length along elements opposite spout,

21% inches.

Distance from bottom or device to seat 26, 1; inch.

Inner diameter of tube 32, inch.

Length of tube 32, measured from under side of diaphragm 28, 11% inches.

Thickness of tube 32 and diaphragm 28, 115

inch.

It will be understood thatv the above dimensions are given for a device intended to dispense approximately 5 cc. of liquid in each operation and that certain slight adjustments of the dimensions will be required to provide the necessary taper for the withdrawal of the molds used in casting, if the parts are to be cast.

The device illustrated is of very simple construction, such that the parts may be readily made of brass, aluminum, plaskons, resins,

waxes, or other suitable material and are such that no expensive or intricate machine Work is required for their production, simple casting, molding, stamping, pressing, drawing or spinning operations being suilicient; the selection of the particular method of fabrication depending, of course, on the type of material selected, etc.

The invention is capable of many practical embodiments, one of which has been described in detail, as will be apparent to those skilled 35 in the art. For example, instead of fastening theV device to a container by internal or external screw threads, it may be fastened by a friction t, for which a suitable gasket may be provided;

. or the container may be provided with a rim 70 or the like at the top, on which a disc, to serve as the diaphragm, fits, a specially constructed cap being provided of such design as to complete the dispensing device; or, in making bottles or the like, the diaphragm and the tube therethrough 75 may be molded within the neck', and a cap having a partition extending at right angles to the plane of the cap may be provided, which, when attached to the bottle or the like, completes the dispensing device; or, the neck of the bottle itself may serve as the inner tube, with the dispensing device of enlarged diameter to flt over the neck so that the neck extends into the proper inner compartment of the device. The new dispensing devices are'not only useful for attachment or use with bottles and similar containers, but also for use with paper or cardboard cartons, cans, etc., in which case they may ad vantageously be constructed integrally with the container, either externally or internally, when the containers are manufactured, as by forming them oi' cardboard, tin, waxed paper, etc., held in place by crimping, beading, clipping, pinching. etc., or by adhesives.

While the dispensing devices have been described With particular reference to the dispensing of liquids in measured and predetermined portions, it is also applicable to the similar dispensing of such solid granular materials as sugar, salt, etc.
