An outer'valve sleeve 24 is arrangedtoslid'e on the inner'valve' sleeve 2l and is provided with ports 25 which are adapted to align'with-'thel ports 23 when the outer valve sleeve 24 is in its upper position.

A pin 26 is secured to theshoulder 22 ofthe inner sleeve 2l andprojects downwardly through a recess 21 formed through the shoulder- 28' "at the lower end of the outer valve sleeve 2'4'. The purpose of this pin 26. is to prevent relative rotation between the valve sleeve 2`I` and' 24. Threadedly connected` to the shoulder onthe outer valve sleeve 24 is the spring housingl 29 which encircles the tubular guide. Z't'o deii'nel an annular recess 30. A compression spring' 3l' "is positioned within thisy annular recessk 305 and is confined between the shoulder 22' on the inner valve sleeve 2l and theA shoulder '32 at the-lower end ofthe spring housing 23.

Threadedly secured. to the lower end of 4the spring housing 2'9 is the vent pipe 33 and at the lower end of the vent pipe 33, the hollow extension rod-34 `is secured and fastened by means. of the locknut 35. At the lower end of the hollow rod` 34Y is a circular flexible disc 36'. A screw 31 and washer 38 are used in securing the disc 36 to the lower end of the hollow rod. 34. The disc is made exible for several' reasonsv as will appear hereinafter and in order that itlmay be inserted through the restricted outlet I3 and neck H of the container. ID.

A hollow cup element 33 is. secured to the hol.- low rod 34 by means of the nut 40 and acts Las astiifener element supporting the flexible. vdisc 35.

Means are provided for actuating. the valve sleeve 24 to bring the valve ports 23land 25 into alignment, and as illustratedsuch means include a` bifurcated post 4l securedv on ther cap I8 'andl carrying a pin 42 for pivotally supporting an actuating crank 43. A .thumb pad ifi is providedon one end of the crank 63 and atlthe other end the crank i3 is pivotally connected to an actuating rod 5- W-hich extends downwardly through the opening 45 .at the upper end of the cap kI8 and throughv the tubular guide 2li.. The Ilower endoi the actuating `rod 45 is threadedly received in a dam element 33a threaded into. the vent pipe '33.

From the above description it will be: understood that when the actuating crank wismoved from its normal position, indicated by lthe dotted lines in -ligiire 1,.,to'thgimsition indian-ted by' the fsolid. linesQthctmd 4E, together 4witlfl the vent' pipe l33, spring housing 2B, and cuter valt/Te sleeve 24, is iii'ftcd vertically. .liftizigmotion the hollow rod t4. passage terminates in vent ports e drilled laterally into the lower end of the hollow rod 34. .The ports E@ lead into an annular space within ports 5i) into the annular space 5I.

brings the ports 25 from their inoperative position to their position of alignment with the ports 23, thereby establishing a flow path from the interior of the neck II to the discharge port I9. The same lifting action by the rod 45 serves to lift the hollow rod 34 secured on the lower end of the vent pipe 33 and thus bring the flexible disc 36 from its normal inoperative position, as indicated by the dotted lines in Figure 1, to its operative position indicated by the full lines.

In its operative position the flexible disc 36 contacts the inside of the container Ii) to form a seal and to dene a measuring chamber 41 within the neck II of the container I!! and between the disc 3S and the upper end of the stationary body I4. When the container is inverted from the position shown in Figure 1 and when the thumb pad 44 is actuated to bring the valve ports and 23 into alignment, the disc 3e prevents ladditional now of fluid from the interior of the container ii) into the chamber 4i within the neck portion i i sc that only the fluid within .the chamber 41 is discharged through the port IS.

Means are provided for venting the chamber 41 during the in erval of discharge therefrom in order to bring air into the neck of the container and thus facilitate discharge through the port IS.

`As shown in the drawings, this vent means includes the opening 4 in the upper end of the cap I8 and the annulus 43 between the actuating rod 45 and the tubular guide 2?). The vent passage, which includes the annulus 4B, continues downwardly through the vent pipe 33 through the passages 43 formed through the dam 33a and into The lower end of this vent the cup member 39. When the iiuid within the chamber 41 is being discharged through the port I9, air from the atmosphere is admitted through the vent passage including the annulus 4S and hollow rod 3E and flows outwardly through the Since the pressure of the uid within the chamber il adjacent the disc 3B is somewhat below atmospheric pressure during the interval of discharge, the air admitted into the space 5i escapes radially outwardly past the flexible disc 36 and into the chamber 41. The discharge of fluid through the port I9 is therefore rapid and efficient.

When the measuring valve assembly is initially vinserted into the neck of container lli, the flexible disc 35 cooperates with the rim on the cup memy, ber 3S to prevent entry of liquid into the annular space 5 I, and hence no liquid enters the vent passage. When the container is inverted, the chamber 41 lls with liquid, but the seal between the flexible disc 35 and the cup member 3S again prevents entry of liquid into the vent space 5l.

`Actuation of the thumb pad however, serves Hto flex the` disc 36 against the inside of the conn ltainer wall and thereby materially diminish the Lsealing eiect between the flexible disc and the cup member fpartially destroyed, the air within the annulus instantly available at time of discharge to enter 'i the chamber c1 and hence to promote nonturbu- 'lent ow of liquid from the discharge orifice I.

While the container I0 is held inverted in pouring position a number of small glasses may be lled, discharging the same amount of liquid into each glass. It is not necessary to re-invert the container in order to fill each glass. When the liquid in the chamber 41 has been discharged into the first glass, the thumb pad 43 is released to permit the spring 3| to close the ports 25 and 23 and then to move the exible disc 36 out of contact with the inside of the container I0. The air in the chamber 41 which entered through the vent passage is then displaced by uid entering the chamber 41 from the main part of the container I9. The disc 36 and rim on the cup element 39 cooperate to prevent entry of uid into the'vent passage while the chamber 41 is filling.

In order to change the volume of fluid contained within the measuring chamber 41, a displacement element 52 may be provided which is received on the rod 34. The displacement element 52 is formed of a size to displace the proper amount of fluid, and if necessary may extend upwardly to cover all or a portion of the spring housing 29, as well as the rod 34, as will be readily understood.

Having fully described my invention, it is to be understood that I do not wishto be limited to the details herein set forth, but my invention is of the full scope of the appended claims.
