7 Claims. (Cl. 221-14) 'Ihis invention relates to dispensing means and more particularly to a novel form of nozzle or spout which may detachably engage some container whereby liquids and granulated solids may be readily dispensed from said container.

An object of the present invention is the provision of a dispensing nozzle or spout which will permit the dispensing of substances rapidly and which dispensing may be readily stopped at the will of the operator. In the case of liquids, the device so functions that there is no drip from the nozzle or spout when flow of liquid therethrough is shut oi.

The invention contemplates a novelV method of allowing air to enter any container upon which said nozzle or spout is mounted soV as to assure steady flow of a liquid or other substance through said nozzle or spout. The invention is adapted for readily-permitting the dispensing of viscous liquids, and to this end, the device of the invention is so constructed as to at all times maintain the air opening clean of said'liquid.

Other objects include an invention which is simple in construction, easily applied to a container, and inexpensive in cost of manufacture.'

With the above mentioned and other objects in View', the invention consists in the novel and useful provision, formation, construction, association, and relative arrangement of parts, members and features, all as shown in certain embodiments in the accompanying drawing, described generally, and more particularly pointed out in the claims.

In the drawing: v

Figure 2 is a sectional View on the line 2-2 of Figures 1 and 3,

Figure 3 is a vertical sectional view oi the invention shown in Figures 1 and 2,

Figure 4 yshows a modified form of the invention as applied to a container having a screw neck,

Figure 5 is a View taken 90 degrees from the showing of Figure 4,

Figure 6 is a sectional view on the line 6-6 of Figure 5,

Figure 7 is a sectional view on the line'I- of Figure 6,

Figure 8 is a longitudinal sectional View of a modied form of the invention shown by Figures 1 to 3, inclusive, and,

Figure 9 is a view looking in the direction of the arrow 9 of Figure 8.

Referring now to that type of the invention y a body portion or nozzle 3 which has a tapered outer surface 4 for a portion of its length. The body is reduced at 5, and the-reduced portion as well asthe body is formed with a through bore 6 forming a duct or passage way. The axis of the bore or duct 6 is eccentricto the axis of the body portion 3. In transverse section the body 3 is substantially heart or pear-shaped, see Figure 2, and what would be the neck of the pear is cut iaway segmentally, as shown at 9, it being observed that the length of the body to said cut 9 is less than the length of the bottom portion of the body, see Figure 3. Conforming to the shape of the body and provided with a bore is a disc II), the tube 5 being passed through the opening thereof, so that a portion of said disc will bear against the end II of the body. This construction permits some element to be positioned between a face of the disc and the face l2 of the body. The body and the disc may be provided With one or more aligned openings, the opening in the body being screw-threaded whereby a screw or similar means, such as indicated by dotted lines at I3, may hold said disc to said body.

'1 The body is provided with two concentric bores of different diameter, as indicated at I4 and I5, and the disc is provided with a bore I5 in axial alignment with said bores I4 and I5. Adapted to extend through the bores I4, I5, and I6 is a l stem, shaft or trunnion Il, to which is secured a valve I8 of the disc type. The disc is held to the stern or trunnion in any approved manner, such as by passing a pin I9 through aligned openings therein. Within the bore I 4 and Wrapped around the stern or trunnion is a coil spring 20. One end of said spring bears against the ledge or shoulder 2l formed by the different diameter bor-es I4` and I5 While the opposite end of the spring bears against a pin 22 transversely passed through the said stem or trunnion whereby the valve is always urged tightly against what may be termed the forward end surface or seat 22a of the body or nozzle.

At 23 is a second spring, one end of which is secured about the pin 22 and the opposite end of 25 is an actuator for the stem or trunnion in the form of a handle or lever, this lever including an elongated part formed at one end with a finger piece 26. The lever has a bent end extremity 21 provided with a bore through which said stem or trunnicn is passed, as shown in Figure 3 and the said stem or trunnion is fastened to said end 21 by pinning or otherwise, as indicated at 23. The lever has a flat head portion 29, which engages the shoulder 30 formed by the transverse cut 9, and likewise a curved portion 3|. Thus, when the lever is in the position shown in Figure 2, the valve disc covers the end of the body and closes the opening therethrough. When the nger, such as shown in Figure 1 at 32 moves the lever or handle in the direction indicated by the arrow of Figure 2, the valve disc is moved clockwise to uncover the bore 6 so that any content within the bottle 2 may be poured outwardly of the said bore. Surrounding the part is some means, such as cork, rubber, or the like 33, so that the device may fit tightly within the neck of the: bottle 2.

Referring now to the form of the invention shown in Figures 4 to '7, inclusive, Figure 6 illustrates the mechanical parts wherein 50 is a cap internally provided with screw-threads 5|, whereby the said cap may be threaded to the neck of a container, such as a jar containing mayonnaise, granulated sugar, or other substances. The cap above the screw-threaded area has an enlarged chamber 52 and an outlet port 53 communicates between the chamber 52 and the outer surface of the cap. The top of the cap carries a diametrical enlargement 54, which enlargement is provided with concentric bores of different diameter, as illustrated at 55, 56 and 51. Passed through said bores is a stem or trunnion 58 carrying at one end a valve 59 in the form of a disc, the disc being pinned to the stem, as shown at 50. This disc when in one position, closes egress through said outlet port, and in a second position allows egress therethrough,

The coil spring 5| within the bore 56 surrounds the stem or trunnion and bears against a shoulder 62 for one end of the spring while the opposite end of the spring engages a pin 63 passed transversely through the stem or trunnion. This said spring urges the stem to the right, viewing Figure 6. The end 64 of the stem is reduced in diameter and carried on said reduced diameter portion and pinned thereto is a lever 65. This lever is substantially of flat stock given a structural twist to provide a nger portion at 65 and a base portion 61, the edge of the base being substantially straight at 68 and then gradually curved, as shown at 69. The flat portion carries a transverse pin received within the confines of an arcuate slot 1| formed in the cap. This arcuate slot communicates with the chamber 52. It is to be observed that the foot of the lever is enlarged in width so that when the lever is in the position shown in Figures 5 and 7 the pin 10 is adjacent the right hand end of the arcuate slot 1| with the said head end of the lever closing the slot 1| throughout its length. When the lever 65 is compressed in the direction of the arrow of Figure 5, the pin 10 travels within the slot 1| and a portion of the lever uncovers said slot so that air may enter the chamber 52. In order to manipulate any container, such as shown at 12, I have provided a handle 13 secured to the cap. This handle may assume any form, such as the curved form illustrated in Figure 4, the handle having a portion adapted to be secured by screw 14 to the 75 cap, and one end 15 of said handle is enlarged and recessed or chambered, as shown at 16. Within this recess and secured to the enlargement are a pair of at prongs or pins 11. The end of the enlargement is adjacent the foot of the lever 65. A coil spring 18 has one end received between the prongs 11 and the opposite end passed through a transverse opening in the foot of the lever, as shown at 19.

Figure 8 illustrates a modied form of the invention shown in Figures 1 to 3, wherein I have provided in combination with the device means whereby a measured quantity of liquid may be dispensed. The device as shown includes a body formed in two parts |00 and |0|, which may be securedtogether through the medium of screws |02 received in tapped openings in the body part |00. The body parts are both provided with coaxial longitudinal bores |03 and |04, within which liquid may be received and likewise dispensed therefrom. The forward end of the body part |00 has positioned thereon a disc valve |05. 'Ihis disc valve has eccentrically secured thereto by pinning or otherwise a shaft |06, which shaft is within bore |01. Within the bore |01 are two coil springs |08 and.|'|."9, both of which surround the shaft. The spring |08 is attached to the shaft and bears against an end Wall of the body part so as to normally urge the shaft inwardly and thereby press the disc valve |05 tightly against the end of the body |00. In effect, a ground-lit engagement occurs between the disc valve and said end to prevent any liquid from escaping past the valve when the valve is closed over the opening |03. The spring |09 functions to normally maintain the valve closed and to resist turning movement of the shaft. The body part |0| is provided with a bore ||0 coaxial with the bore |01. Within this bore is a shaft in axial alignment with the shaft |06. One end of said shaft carries a disc valve 2 which may be swung to position the same over the opening |04 (see Figure 9). Surrounding the shaft is a coil spring ||3, this spring having one end fixed to the said shaft, whereby the disc valve is urged into tight engagement with its valve seat. The inner ends of both shafts |106 and are externally squared, as shown at ||4, I5 and the body |00 is cut away in such a manner that a lever 6 may be received between both body parts |00 and I'EII and positioned on the squared portions of the shafts. In this manner, the single spring |09 acts to resist turning of both shafts when the handle is moved. The relationship of the disc valves is such that when one valve is opened the other is closed. 'Ihe body part |0| has a reduced diameter portion upon which is received an annular cork whereby the instrumentality as a whole may be positioned within the neck of a bottle or similar object.

The operation, uses and advantages of the invention just described are as follows:

First, referring to the form of the invention illustrated in Figures 1 to 3, and assuming that the device is secured in the neck of a bottle, as shown in Figure 1, movement of the lever in one direction by the finger 32 engaging the finger piece 26, will tend to tighten the spring 23 which lnormally holds the valve disc positioned over the end of the body. Movement of the lever against the spring will unseat the disc and thus permit any liquid within the bottle Vto pass through the bore 6 and outwardly thereof.' The moment the handle is released,the spring 23 will rotate the valve disc to a closed position and cut off any flow of liquid through the bore l. The spring 2B always holds the valve disc tightly against its seat. By way of illustration, it masT be said that the spring 29 is normally under a tension of approximately ve pounds. Thus, as there is a ground t engagement between the valve disc and its seat, the valve when closed is fluid tight.

The form of the invention illustrated in Figures 4 to '7 operates on the same principle as the device just described in that it has a spring for normally urging the disc valve into seated position and a spring for returning the valve over the outlet port when the handle is released. However, as the form of the invention illustrated is adapted to handle viscous liquids, such as syrups, mayonnaise, and the like, such substances may clog the air inlet opening 1| and to overcome this, the pin 'l0 moves within the slot 'H to clear said air opening each time the handle is actuated.

The operation of the form of the invention illustrated in Figures 8 and 9, is as follows: Normally the operator, with the device of Figure 8 positioned within the neck of a bottle, will tip the bottle so that the liquid within the bottle may be received within the bores |03 and |04. We will say that the bores will hold the equivalent of one jigger. When the handle I I6 is moved, the valve H2 will be Closed over the opening |04 and the valve opened. Thus, one jigger of liquid is dispensed. Upon releasing the lever, the operation is repeated.
