April`l6, 1940. A. TERKEL VENTED VALVE Filed Jan. 17. 1938 INVENTOR. ABRA HAM TERKEL B-Y M@ ATTORNEY.
Patented Apr. 16, 1940 UNITED sTATEs PATENT OFFICE 6 Claims.
This invention relates to a vented valve for containers.
The primary object of the invention is to provide a vented valve or closure which is adapted to be readily attached to the outlet of a container, vessel, bottle or the like in such a manner' as to act as a vented spout for the controlled discharge of uid from said container.
Another object of the invention is to provide a vented valve which is adapted to act as a closure for a vessel or bottle or the like container, and which is provided with means to simultaneously"open and close a fluid passage and an air vent through the valve, said valve being so arranged that it can be readily manipulated by one hand for pouring out the contents of the container.
' Another object of this invention is to provide a vented valve which is highly useful and simple in.
construction. Convenience of arrangement, lightness and comparative inexpense of manufacture are further objects which have been borne in mind in the production and development of the invention. I am aware that some changes may' be made in the general arrangements and combinations of the several devices and parts, as well as in the details of the construction thereof without departing from the scope of the present invention as set forth in the following specification, and as deined in the following claims; hence I do not limit my invention to the exact arrangements and combinations of the said device and parts as described in the said specication, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.
With the foregoing and other objects in view, which will be made manifest in the following de- `tailed description and specifically pointed out in theappended claims, reference is had to the accompanyin'g drawing for the illustrative embodiment of the invention, wherein:
Figure 1 is a sectional view of my vented valve showing the same in closed position.
. Figure 2 is a sectional view of my vented valve showing the same in open position. f
Figure 3 is an .end view of my valve, the disc valve being partly broken away to expose to view the air vent.
Figure 4 is a side view of my valve.
Figure 5 is a sectional view of a vented spout constructed in accordance with my invention.
In its general organization my invention includes a valve body which has an end that ts over the outlet of a container, for instance over the mouth and neck of a bottle or the like, a iluid passage through said body which extends from said`end of the valve body to an outlet Y spout, an air vent conduit which extends from the 5 intake end of the fluid passage to the exterior of the body, and a valve common both to the fluid passage and to the air vent conduit to simultaneously open and close both. The body of the valve is preferably so constructed that the valve may be held between the index and middle fingers of the hand and the outer end may be pressed by the thumb of the same hand for engaging a valve actuating element thereat.
In detail my invention includes a tubular valve 15 body 6 around an open end of which is a cup shaped securing flange 1 which latter is threaded at 8 either internally as in Fig. l, or externally as in Fig. 4 or otherwise adapted to be secured over the outlet 9 'of a container such as a bottle or 20 vessel, so as to locate said tubular valve body 6 in said outlet 9. Through the open end adjacent the ange 'I is formed a passage II for ilow Vof fluid.
In a rim I 2 o'f the open end of the valve body 6 is a packing made of rubber or other compressible ma- 25 l teria] which forms a valve seat I3. The other end of said valve body 6 is closed by a wall I4 on the outside of which latter is a cylindrical, hollow guide projection I6. l
The disc valve I I lits over the valve seat I3. A valve stem I8 extends from the disc valve I'l through an aperture I9 in the end wall I4 of the valve body 6 and into the interior of the hollow guide projection I6. On the outer end of the valve stem I8 is threadedly secured a thumb head 2I which latter is hollow and is so shaped as to slidably t over the exterior of the guide projection I6. A coil spring 22 in the recess of the guide projection I6 and around the stem I8 bears at one end against the wall I4 and at the other end against the inner face of the head 2| so as to normally urge the head 2| outwardly and away from said body 6 thereby to seat the valve I'I. In order to unseat the valve I'I it is only necessary to press the head 2| toward the body 6 and against the action of the spring 22.
The passage I I for the fluid is continued at an angle so as to form a lateral spout 23 at one side of the body 6. Along the wall of the passage II opposite to the side where the spout 28 is located is a conduit 24 preferably formed integral with the interior of the valve body 6. This conduit 24 extends from the intake end of the valve passage II to a point beyond the cup flange 'I and then to the outside of the body 6 at a point adjacent shoulder 28 of the body 6 is left cylindrical so as to form a narrow rim flange at the outer end of each ilattened side 21 against which the lingers holding on said flattened sides 21 may bear as the thumb is being pressed against the head 2| for opening the valve. This also allows a firm grip on the valve.
In the form shown in Fig. an outlet body 29 is exteriorly threaded or otherwise adapted to be secured onto a container outlet, so that the flange 3| limits `the entry of the body 29 into the outlet of a container. The outer end of the outlet body 29 is curved to form a spout 32 at an angle to the outlet passage 33 of the same. An air conduit 34 is formed integrally with the wall of the passage 33 on a side opposite to the direction of the spout 32. The air conduit 34 extends from the intake end of the uid passage 33 and communicates with the atmosphere at a point 36 beyond and outside of the ange 3|.
It is to be noted that it is preferable to have the air vent extend along the inside of the fluid passage on a side opposite to the direction of the spout. Thus when fluid flows toward the spout in the natural position of the spout pointing downwardly then the tendency of the fluid is to ow along a side of the passage below the air conduit. At any rate the aforesaid relative position facilitates the venting action of the air conduit. It is also to be noted that the air conduit extends from the point of intake of the valve to an outside point which latter is always outside of the container by reason of its relative position to the secured end of the valve. Furthermore the opening or closing of the valve on its seat automatically opens and closes not only the fluid passage but also the air vent by the same movement of the same valve member, in this instance a disc valve. The valve may be readily secured to the vessel or receptacle and thereafter it is easily manipulated with one h'and as shown.
What I now claim and desire to secure by Letters Patent is:
1. A closure for an outlet comprising a hollow valve body having an intake passage, a spout on one side of said body connected to said intake passage, an air conduit extended from the intake end of the intake passage to the outside of the body on the side of the passage substantially opposite to the spout, and a valve common to the intake end of said passage and to said air vent.
2. A vented outlet device comprising a tubular member, means to secure said member tothe outlet of a container, a spout formed on said tubular member in communication with the passage of said member, and an air conduit extended from the intake end of the passage of said member to the exterior of said member outside said securing means, and a valve to simultaneously cover the adjacent ends of said passage and of said air conduit.
3. A vented outlet device comprising a tubular member, means-to secure said member to the outlet of a container, a spout formed on said tubular member in communication with the passage of said member, and an air conduit extended from the intake end of the passage of said member to the exterior of said member outside said securing means, a valve to simultaneously cover the adjacent ends of said passage and of said air conduit, and resilient means to normally hold the valve in closing position.
4. A vented valve comprising a body having a fluid passage, a side spout connected to the uid passage, an air conduit extended from the intake end of the fluid passage to the exterior of said body, a disc valve to simultaneously cover the adjacent ends of the passage and of said conduit, a valve stem axial to said body extended from said disc valve through the wall of said body, a guide on the outside of said body, a head on the valve stem slidable on the guide, a spring to normally urge the head into Valve closing position, and means to attach the body to a container.
5. In a closure for an outlet the combination with a hollow valve body with a spout to one side of said body and a substantially axial passage from the intake end of said body to the spout; of an air conduit extended from the intake end of said passage to the outside of said body in sub- 40 stantial parallelism with said passage and on the side substantially opposite to said spout, and a valve for simultaneously covering and uncovering the intake end of said passage and the inner end of said air conduit.
6. In a dispensing closure for an outlet, ther combination with the hollow body of the closure adapted to be secured to the outlet of a container and having its outer end closed, a spout on one side of the body, a valve on the open end of the body and a. valve actuating element extended beyond the closed end of the body; of opposed reduced exterior portions on the exterior of said valve body spaced from the outer end of the valve actuating element and conforming to the usual gripping-surface between adjacent. fingers of a hand so as to accommodate the gripping of the closure between two fingers with a third finger of the same hand in position to operate said valve actuating element by pressing at its outer end.
