This invention relatestopouring stoppers for ink bottles and the like, and has for one of its important objects to provide a simply constructed device of this kindwhereby leakage of the ink or other liquid from the bottle 3 or container when the device is not inuse will be effectually prevented.

.It isanotherrob'ect of the invention to provide a pouring stopper of the type in which a removableclosure cap is provided for the liquid dispensing passage and the 1 air vent passage, and in which said passages are so arranged ordisposed With respect to l the structure of the stopper. that back pressure through the vent passage and the raising of the liquidlevel in thedispensing chan I p 7 body sectlon 8, this s de surface of the tapernel or passagewhen the closure cap is applied will be prevented. p q a It is a furthergeneralobject of the invention to provide a pourout stopper of the above kind whichis of suchform and construction withrelation to the outlet end ofthe liquid passage that the flow of the liquid therefrom posed in upright positionand accumulation of the'liquid on the-external surfaces of the stopper avoided. 3 1

With the above and other objects in view, the invention consists in the improved pourout stopper for ink bottles and the like, and in the form, construction and relative arrangement of its several parts as will be hereinafter more fully described, illustrated in the accompanying drawing, and subsequently incorporated in the subj oined claims. In the drawing, wherein I have disclosed one simple and practical embodiment of my present improvements, and: in which similar reference characters designate corresponding parts throughout theseveralviews V Figure 1 is a vertical sectional .view showin one preferred embodiment of thepresent b invention; 3 3 Fig. 2 is a side elevation of the device, the closure cap being applied thereto, and

3 is a similar view with the closure cap removed. 1 I 1 Referring in detail to the drawing, 5 designates the bottle or containerjwhich may be ofany desired form, shape and capacity, and

will be cleanly cut off when the bottle is disisprovidedwiththe usual contracted neck 6. My improved stopper, herein generally indicated at 7is preferably formed from hard rubber or other suitable material. This stop- 3 .per includes a bodysection 8 of cylindrical form having an external thread 9 thereon. One end of this stopper projecting beyond this threaded body section is of general conical or tapering form as indicated at 10 and laterally deflected in one direction from the :99 axis of the stopper to provide anobliquely inclined end ,face 11 of; {reduced area in eccentric relation tothe body section 8 of the stopper. The edge of this end face. at one side of the part 1Q is in substantiallongitudinal alignment with the thread 9 0n the ing'part 10 being concaved as indicated at 12,

while the opposite side surface of said part is convex as at 13.

At the 0th :10 r or inner end of the threaded body 8 of the stopper an annular flange 14 is formed thereonto seatagainst the end face of the bottleneck 6, and;the3diametrically reduced section 15 of thestopper projects in 15 the opposite direction fromsaidflange with respect to the threaded section 8 thereof. A bushing or sleeve of cork or other similar material indicated at 16 is tightly fitted on the reduced end section 15 of the stopper and 50 hasclose frictional engagement with the inner surface of the wallof the bottle neck 6 so as .to provide an air and fluid tight closure for said bottle neck. 1

The stopper 7 is provided with the longi- 3 5 tudinally extending bore or passage 17 through which the ink or other liquid is decanted or dispensed from the bottle. A part of this passage extends in parallel relation to the axis of the stopper, the outer end .90

portion 18 thereof being curved and opening upon the obliquelyinclined end face 11 of the (stopper substantially'in concentric relation thereto. 3 3

The stopper is further provided in suitg ably spaced relation to the passage 17, with anfair vent passage 19 openingat one ofits ends through the part 15 of the stopper and having its other end laterally curved andopening inthe' region of the thread 9 5g rubber is provided at its open end with an internal thread 23 for engagement with the complementary external thread 9 on the stopper. At its closed end, the wall of this cap is formed with a shallow conical internal surface 24, the angle of this surface with respect to the longitudinal axis of the cap, being substantially the same as the angle of the obliquely inclined end surface 11 of the stop-' per 7.

In the use of the device as above described, it will be understood that with the closure cap removed, in dispensing or decanting the liquid from the bottle, upon tilting the bottle from its upright position, the liquid flows outwardly through the passage 17. This cutward How of the liquid will be continuous and uninterrupted, since as soon as the bottle is tilted, the liquid moves away from one side wall thereof sufiiciently for air to freely enter the bottle through the passage and the tube 21. Due to the curvature of the end portion 18 of passage 17 and the oblique angle of the face 11 of the stopper, upon return of the bottle to its upright position, the flow of the liquid from said passage will be instantly and cleanly cut off so that the draining of surplus liquid upon.

the side faces of the part 10 of the stopper is efiectually prevented.

v The cap 22 is now placed over the part 10 of the stopper and engaged with the thread 9. As the ca is turned and threaded downwardly on tie body of the stopper, the inlet of the vent passage 20 is first closed. Thus air from the interior of the cap cannot enter through this passage andraise the level of the liquid so that it tends to expel the liquid through the passage 17, in the event that the bottle is nearly filled to capacity. Upon further downward threading movement of the cap, the tapering or inclined surface 24 thereof is finally brought into close frictional contact with the end face 11 of the stopper, thus providing an absolute seal which prevents any escape of liquid from the passage 17 into the cap 22 and upon the external surfaces of the stopper, in the event that the bottle is tilted from itsupright position. The air trapped within the cap when the latter is applied,

after closing of the vent passage 19-, is forced inward-1 into the dispensing passage 17 and thus provides an air cushion against the downward flow of the liquid through said passage when the bottle is inverted. Therefore pressure of the liquid against the surface 24 of the cap is reduced to a minimum and leakage of liquid past the end face 11 of the stopper into the interior of the cap is effectually prevented.

From the foregoing description considered in connection with the accompanying drawing, the construction, manner of use and several advantages of my present invention will be clearly and fully understood. It will be seen thatI have provided a pourout stopper for ink bottles and like containers, which while exceedingly simple in its construction, will also be efficient and serviceable for the purpose in view and effectually overcomes serious objections which apply to articles of this kind as now generally known and used in this art.

I have disclosed herein an embodiment of the device, which I believe to be best adapted to fully attain the purposes of my invention. It is however, more or less evident that both the stopper and the closure cap might be made in numerous other sizes and other means than that here disclosed provided for attaching or applying the device to the bottle neck. Likewise, as to the form, shape and arrangement of the several detail features as above described, the device is susceptible of more or less modification. Accordingly, itis to be understood that I reserve the privilege of incorporating the essential features of my present invention in such alternative structural forms as may be fairly embodied within the spirit and scope of the appended claims.

I claim l.-A pourout for bottles having a liquid closure member and means for adjustably connecting said member with the pourout, said member having parts operating successively in the adjustment of said member in one direction to first close the inlet end of said vent passage and thereafter seal the outlet end of said dispensing passage.

2. A pourout for bottles having a liquid dispensing passage the outlet end of which opens upon the end face of the pourout and an air'vent passage the ingress end of which opens upon one longitudinal side of the pourout, and a closure cap rem'ovably and adjustably threaded upon said pourout and havingiparts successively operating in the adjustment of said cap in one direction to first close the inlet end of said vent passage and thereafter seal the outlet end of said dispensing passage.

3. A pourout for bottles comprising a body having a tapered end portion extending in divergent relation to the axis of said body and terminating in an end face of reduced area obliquely inclined relative to such axis, said ber havin body having a liquid dispensing passage extending through said tapered end portion and having its outlet end opening upon said inclined end face thereof, said body member being further provided with a vent passage having its ingress end remotely spaced from the outlet end of said dispensing passage opening upon the circumferential face of said member, and a closure cap having an ad justable threaded connection with said body member, the wall of said cap in its adjustment to applied position, first closing the ingress end of the vent passage, and said cap having an internal end surface frictionally engaging said inclined end face of the body member in the further adjustment of the cap to its final position to seal the outlet end of the dispensing passage.

4:. A pourout for bottles comprising a body member having an external thread and liquid dispensing and air Vent passages extending through said body member, said air vent passage having its ingress end laterally curved and opening on theside of said member in the region of the thread, and the liquid dispensing passage extending longitudinally beyond said ingress end of the vent passage and opening upon an end face of said body member, and a closure cap internally threaded for adjustable enga ement with the threads of the body mem er and operating upon adjustment thereon to its applied position to first close the ingress end of the vent passage and thereafter by engagement of an internal end face of said cap with the end face of the body member, to seal the outlet end of the dispensing passage.

5. A pourout for bottles comprising a mema tapered end portion diverging from the dongitudinal axis of said member and terminating in an end face of reduced area obliquely inclined relative to said axis, said member having a liquid dispensing passage having its outlet end opening upon said end face of the body member in concentric relation thereto, the external surface of said tapered end section of the body member at the lower side of the outlet end of said passage being longitudinally concave.

In testimony that I claim the foregoing as my invention, I have signed my name hereto.

ALBERT H. JONES.
