May 28, 1963 s. KIRSCHENBAUM WHISKEIY POUREIR OR SIMILAR DEVICE Filed April 25, 1961 United States This invention relates generally to the bottle closure art, and more particularly to an improved form of pour ing device for use in conjunction with liquid containers of the type disclosed in my prior Patent No. 2,411,435, entitled Liquid Dispensing Device, granted November 19, 1946.
Liquid dispensing devices of the type disclosed in the above-mentioned patent are used in connection with hottles for controlling the flow of liquid from the same, and are adapted to provide for the emptying of the container in the form of drops flowing at a substantially uniform rate. They are also adapted in a modified form for dispensing liquid in streams. The operation of such devices is dependent upon the maintenance of certain balances between the flow of air into the container and the flow of liquid therefrom. Proper initial operation depends upon the passages of the device being free of liquid which might destroy the above-mentioned balance. While the devices disclosed in the above-mentioned Patent No. 2,411,435, are generally satisfactory for the purpose contemplated, it has been found that they are not suitable where it is desired to empty relatively large amounts of liquid over a relatively short period of time without regard to the position in which the container is held, and in a manner in which the flow of liquid can be commenced and interrupted practically instantaneously. Typical of such situations is the problem of pouring oneor two-ounce amounts of liquid from a bottle containing an alcoholic beverage, where the problem includes not only the rapid pouring of a predetermined amount of liquid, but also the substantial elimination of all spilling which invariably occurs during a hasty pouring operation.
Attempts have been made in the pouring devices in which the flow of liquid has been controlled by restricting the passage of air into the bottle when the bottle was in inverted condition, but each such device proved incapable of controlling the initial impact of the liquid thrown against it when the container was suddenly turned into a pouring position. Each impact resulted in a misdirected spurt of liquid. Attempts to overcome this difiiculty by imposing restrictions generally resulted in a slowing up of the flow of liquid to an impossible degree. The whiskey pourer commonly in use at bars relies upon elongated tubes projecting deeply prior art to provide into and far out of the mouth of the bottle. It is very unlikely that a suitable closure could ever be designed for it.
It istherefore among the principal objects of the present invention to provide an improved pouring device in which the above-mentioned disadvantages have been substantially eliminated.
Another object of the invention lies in the provision of an improved pouring device of the class described Which will permit the pouring of amounts from one to two ounces of relatively thin liquid in as many seconds of time, and with substantially no spilling while applying only ordinary care.
A further object of the invention lies in the provision of a pouring device possessed of the above advantages which may be used in conjunction with capping devices known and existing in the prior art, without the necessity of removal of the same prior to capping the bottle.
A still further object of the invention lies in the provision of an improved pouring device of the class de- 3,0l,373 Patented May 28, 1963 scribed in which the cost of fabrication may be of a very low order, with consequent wide sale, distribution and use.
A feature of the invention lies in the fact that the device may replace a conventional cork or stopper, thereby eliminating the necessity of removing the same for each pouring operation.
Another feature of the invention lies in the unusually attractive appearance presented by a container equipped with one of the instant devices.
Still another feature of the invention lies in the fact that the same may be formed from moldings of synthetic resinous material, with a complete absence of sealing gaskets, liners, and the like.
These objects and features, as well as other incidental ends and advantages, will more clearly appear during the course of the following disclosure, and be pointed out in the appended claims.
In the drawing, to which reference Will be made in the specification, similar reference characters have been employed to designate corresponding parts throughout the several views.
FIGURE 1 is a view in perspective of a first embodiment of the invention in use in conjunction with a conventional long-necked bottle.
FIGURE 2 is an enlarged longitudinal sectional view of the first embodiment in inverted condition, showing the passage of air and liquid through the device during operation.
FIGURE 3 is a similar sectional view showing the device in position for pouring with diminished flow.
FIGURE 4 is a side elevational view of an alternate form of the first embodiment.
FIGURE 5 is a vertical sectional view showing a sec ond embodiment of the invention.
FIGURE 6 is a similar sectional view showing an alternate form of the second embodiment.
FIGURE 7 is a plan view of the second embodiment as seen from the plane 7-7 in FIGURE 5.
In accordance with the first embodiment of the invention, the device, generally indicated by reference char acter 10, is shown in the drawings posit-ion upon a conventional whiskey bottle, generally indicated by reference character 11, the bottle 11 including an elongated neck 12 having an interior bore 13 and a beaded lip 14. The device 10 comprises broadly a first outer element 15 and a second inner element 16.
' upper edge 29 of the inner tubular member 25, are in nonco-planar relationship, but it is to be understood that such showing is purely exemplary, as the device 10 may be modified to accommodate those cases where this relationship is not desirable. When in use, as illustrated in FIG- URES 2 and 3 in the drawing, air flows in the direction of the arrow 30 through the vent 27 to permit liquid to flow in the direction indicated by the arrow 31 as a continuous stream. The flange member 19 includes a cylindrical member 33 having a bead 34 thereon adapted to engage the lip .14 of the bottle 11, as is well known in the art.
The second inner element 16 is preferably molded integrally from suitable synthetic resinous material, and includes a first cylindrical member 38, the outer surface 39 of which corresponds in diameter to (that of the bore 13 of the neck 12. -A flared rim 40 is adapted to engage the end of the neck 12, to prevent the element 16 from fallinclination (FIGURE 2).
3 ing into the bottle 11, and to position the element 16 coaxially with respect to the element 15.
Extending from the lower end 4 1 of the first cylindrical member 38 are a plurality of supporting finger members 42 which engage the upper edge 4-3 of a second cylindrical member 44, the finger members 42 in conjunction with the first and second cylindrical members 38 and 44 defining a plurality of generally rectangular openings 45. It will be observed that the outer diameter of the second cylindrical member 44 is substantially less than that of the first cylindrical member 38, permitting substantial flow of liquid to the openings 45. The lower portion of the second cylindrical member 44 is of generally tapered configuration as indicated by reference character 46, and in- .cludes a transverse wall 47 having a vent opening 43 therein.
During operation the volume of fiow is determined by the head of liquid, which in turn is determined by the inclination of the bottle, with maximum flow at maximum The liquid passes through openings 45 into cylindrical member 38 as individual streams directed against each other, dissipating or checking their momentum and preventing the liquid from spurting through the interstices St between the outer and inner members 20 and 25, respectively.
Turning now to the alternate form of the first embodiment, parts corresponding to those of the principal form have been designated by similar reference characters with the additional suffix a.
The alternate form of the embodiment differs from the principal form in the relocation of the openings 45a in an upward direction to increase the distance between them and the vent opening 48a. This modification is particularly suited for very thin liquids, in that the impact of liquid at the point of ingress through the openings 45a is absorbed and dissipated by immediate contact with theouter surface of the outer tubular member 24) with a consequent total elimination of splashing of the liquid in the interstices 50a between the inner and outer tubular members 20 and 25, respectively.
This form may also be employed as an adjunct to a dropper where the inner tube of the outer element is shortened to lower the eifective head of liquid in the inner tube. This combination permits the dispensing of liquid in drops from bottles as large as six ounces, whereas with the absence of the inner element dispensing in drop form is limited to bottles having capacities of two ounces and less, depending on the liquid being dispensed.
Turning now to the second embodiment of the invention, parts corresponding to those of the first embodiment have been designated by similar reference characters with the additional prefix 1".
The second embodiment of the invention differs from the first embodiment of the invention in the elimination of the inner tubular member 25 with retention of the support members 22, 23 and, 24 which form pockets or interstices for controlling the entrance of air past the outflowing liquid.- The second embodiment has application principally for the dispensing of relatively viscous liquids, and may be used with relatively large containers or bottles.
Turning now to the alternate form of the second embodiment, parts cor-responding to those of the principal form have designated by similar reference characters with additional suffix a.
The alternate form of the second embodiment differs from the principal form in the provision of an inner wall 160a, the inner end 161a of which is connected to the wall 147a to surround the, vent opening 14 8a, and the outer end 16 2a of which lies adjacent the openings 145a. The alternate form of the second embodiment is also adapted for usein handling relatively viscous liquids, there being a tendency for the inner tube 160a to accumulate fluid within the. same owing to capillary action which tends to seal the vent opening 148a during the initial period in which free liquid flows from the bottle. A discussion of the theory of the flow of free liquids from containers will be found in my Patent No. Re. 24,695, dated May 19, 1958.
It may thus be seen that I have invented novel and highly useful improvements in pouring devices, in which there has been provided a means for accurately dispensing relatively large quantities of a liquid with convenience, accuracy and a short period of time during which the flow :occurs. The structure performs its function by virtue of the presence of two controlling elements, including an inner element which controls flow and prevents gushing to a chamber formed between the inner element and an outer element disposed within the mouth of the neck of the bottle. The outer element subsequently controls the flow from this chamber outwardly of the bottle. In each case, the maximum possible flow of liquid through the inner element is substantially less than the maximum permissible [flow through the outer element, so that the function of the inner element is not by-passed by the filling of the chamber formed between the elements.
Although the disclosed embodiments show the inner and outer elements formed as separate bodies and supported in predetermined mutual relation by engagement within the neck of the bottle, under certain conditions it may be desirable to form the device as an integrated unit to enable the same to be inserted into the neck of the bottle at a single station on a conveyor belt assembly line. In such cases, the elements may be formed to be subsequently cemented or otherwise attached to each other using an interconnecting member (not shown) if necessary.
I wish it to be understood that I do not consider the invention limited to [the precise details of structure shown and set forth in this specification, for obvious modifications will occur to those skilled in the art to which the invention pertains.
