REGULATING POUROUTS FOR BOTTLES Filed Oct. 27. 1949 TIE 3 3/ ZNI/Z/YTOF Patented May 26, 1953 UNITED STATES PATENT OFFICE REGULATING POUROUT FOR BOTTLES Edward Sokolik, New Brighton, Minn.

I Application October 27, 1949, Serial No. 123,840

6 Claims.

My present invention relates to improvements in pouring spouts for bottles more in particular for liquor or pharmaceutical bottles.

The principal object of the invention is to provide a pouring device provided with an air vent,

and adapted for easily and precisely regulating,v

in the process of pouring, the volume of the pouring stream so as to fill a whisky glass or a pharmaceutical measure to the exact level without exercising any special effort or dexterity by the bartender filling the glass or pharmacist filling the dru measure.

A further object is to provide a pouring device with a gravity operative means for opening the pouring orifice as the bottle is being tilted and closing the orifice as the bottle is being arighted, the means avoiding the pouring stream, and

Another object is to provide a pouring device with a gravity operative means for opening the air passageway as the bottle is being tilted and closing the passageway as the bottle is being arighted.

Other objects and advantages will be apparent as the specification progresses.

Invention resides in the combination and arrangement of the pouring passageway and the air passageway and providing said passageways with gravity operative means for opening and closing said passageways in the process of pouring as the bottle is being tilted and arighted, respectively, the means for opening and closing the pouring orifice being adapted to avoid the pouring stream. 1

Fig. 8 is a plan view of the humped to edge of the device corresponding to Fig. 2 omitting the part in section.

Figs. 6, '7 and 8 illustrate one form of my pour-.

ing device, which includes a combined stopperportion l1 and a spout-portion l8, either of suitable material.

The device may be made in a unitary body, or

it may be made in two sections (not shown) transversely joined by a slip or other joint. As illustrated, it is preferably made of lateral hemisections II and i2 sealably joined in a medial plane I3. This structure facilitates the manufacture of the device as the pouring pass-ageway 22 and air assageway l5 are formed in complementary lateral hemi-passageways, one in each lateral section II and I2 and adapted to register at the medial plane l3 when the said sections II and 12- are sealably joined together.

A pouring passageway 22 and an air passageway I5 extend from end to end of the device, the air passageway l5 extending, with the device in a horizontal pouring position, along the top of, but separated from the pouring passageway 22 and being substantially of a uniform crosssectional area throughout its length. These

passageways

22 and 15 extend horizontally and normally parallelly superposed through the stopperportion I1 and preferably of elliptical shape laterally, and preferably somewhat larger at their orifices and 23, respectively' In the spout-portion IS, the bottom 24 of th pouring passageway 22, in a horizontal pouring position, is deflected arcuately downwardly nominally twenty-five degrees and is humped at the top 25 thereof adjacent the stopper-portion l1 and sloping, generally in a straight line, 29 to the free end of the spout-portion IS. The lateral sides 28 of the pouring passageway 22 converge from the generally rounded orifice 26 thereof to the highest part 25 of the pouring passageway 22 adjacent the stopper-portion N. This passageway 22 is transitioned from. generally rounded orifice at the end to a narrow and high portion M in the form of a hump 25, the cross-sectional area throughout the said pouring passageway being substantially uniform, and in the process of pouring, a major change in the tilting of the bottle at is necessary to produce a minor change in the volume of the pouring stream requiring less precision and skill on the part of the bar-tender in serving liquors such as whiskey or on the part of the pharmacist in prescribing. The pouring is easily and precisely regulated and the conventional pouring of too little or too much is done away with.

The outer periphery of the spout-portion l8 is i1lustrated as being generally in symmetry with the inner periphery thereof and the air pasvertical plane of said spout-portion l8.

The stopper-portion I1 is telescopically pro- 3 vided preferably with a resilient ferrule 2| of rubber, cork or the like, and may be provided with a flanged cap 19 which may be brimmed.

I prefer to deflect the free end of the spoutportion l8 downwardly nominally twenty-five degrees and to form the plane of the end of said spout-portion H2 at right angles to the axis of the free end thereof. This arrangement produces an overshot plane of about forty-five degrees to cooperate with'the specific design of my gravity operative pivotally biased lid 26 to open and close the

orifices

26 and 27 avoiding the pouring stream. To attain this mode of operation, I provide, as illustrated, my spout above the orifice thereof with a cantilever arm 3!, provided with a pivot bore at the end thereof, and projecting forwardly from the end of the spout-portion l3 sufficiently to cooperate with the cantilever arms 32 to avoid the pouring stream in the process of tilting and arighting the bottle 30.

The arms 32 are parallelly spaced apart and project forwardly from the top of the front of the lid 16 straddling the arm 3i of the spoutportion Id. In View of the device being made in two lateralv hemi-sections, it is preferable to provide the lid 16 with one arm and the spout with two arms, one on each lateral section. The arms 32 are provided with registering pivot bores registering with the bore of the arm on the spout and provided with a pivot 9. In a horizontal pouring position, the lid I6 will open at an angle of some 80degrees depending on the relative weight of the lid 16 and its arm 32.

Figs. 1 to illustrate a modified form of the invention. The only difference isthat the air passageway 15, instead of extending from the hump 25 along the top 29 substantially in a straight line to the free end of the spout, is directed from the back of the hump 25 in the form of a reverse curve 34 emerging as an inlet air vent 36. 1 The back of the hump 25 is preferably shaped in the form of a nose 33 to provide accommodation for the curve 34. This curved portion of the air passageway 15 not only serves as such passageway, but also serves as an enlarged runway 34 fora gravity operative ball valve 35, which is placed in before the sections are sealed together. This runway is provided at the inner end thereof with an air bypass and ball stop 37. While this may be accomplished in various ways, I prefer to provide the runway with a ball valve 35 small enough to permit the air to by-pass the valve at the inner end, Where I provide the stop 3'! for the ball valve 35. At the outer end of the runway 34, I provide an annular seat for the ball 35 by reducing the diameter of the runway. This arrangement is peculiarly adapted to hemi-lateral construction of the device, as the ball is placed into the runway 34 before the hemi-lateral sections are sealed together.

The ball valve 35 rolls in the runway 34 from the annular seat that encompasses the air vent 35 to the stop 31 in the inner end opening the air vent 38 as the bottle 30 is being tilted and rolls from the stop 31 in the inner end to the annular seat and closes the air vent 35 as the bottle 30 is being arighted. It is to be understood that the form of my invention, herewith described and shown, is to be taken as a preferred example of the same, and that various changes in the shape, size "and arrangement of the parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims.
