UNITED STATES- PATENT OFFICE 2,099,292 DRIPLESS DISPENSING DEVICE Mortimer J. Brown, Niagara Falls, N. Y. Application August 25, 1 936, SerialNo. 97,74: 9 Claims. (01. 22 1-2s).

This invention relates to the production of carbonated beveragesand particularly to a-dripless dispensing device foruse in adding syrups or the like to carbonated water.

5. vI have found that in order to retain the maximum' amount of carbon dioxide in carbonated beverages it is essential to avoid stirrin'gor agitation. It is also necessary to thoroughly mix the syrup with the carbonated water in order'to 10 obtain auniform beverage. I

A- satisfactory beverage can be obtained without'appreciable loss of carbon dioxide by adding the; syrup to the carbonated water in the form of a small stream orv streams which are discharged 15 from a dispensing device held near the level of the water. The small stream of syrup disintegrates as it falls. to the bottom of the carbonated water and thereby produces a uniform mixture of the type required.v Beverages formed in this way have a much higher carbon dioxide content 20 than beverages formed by adding the carbonated water to the syrup under high pressure or by stirring the mixture in the glass as by a stirring device.

It is accordingly an object of the present invention to provide a dispensing device capable of dispensing syrup in a form suited for the above purpose. Another object is to provide a dripless dispensing device which is simple to manufacture and to manipulate, and is efiicient and sanitary inoperation. Various other objects and advantages will be :apparent as the nature of the invention is more fully disclosed. a

-In one embodiment I accomplish these objects by providing a container for syrup or the like having a cap or cover in which diametrically opposite air vent and pouring openings are formed. The air vent is designed so that the contents of the container is prevented from splashing through the vent and reaching the exterior of the cover. It is also self-cleansing so that the tendency to become cloggedwith syrup is reduced to a minimum. The discharge or pouring openings are adapted to discharge the syrup in small streams andare so arranged that any syrup which remains therein is drawn back toward the interior of the bottle when the pouring operation is stopped. V v

These and other novel features which are characteristic of the invention will be better understood by referring to the embodiment shown for purposes of illustration in the accompanying drawing, in which:

' Fig. 1 isa vertical section through a portion of d 55 a container. or bottle showing; the, cover attached thereto, same being taken on line l--l of Fig.4;

M Fig. 2 is a front elevation of the container and cover; v v

Fig. 3 is a side elevation thereof; and,

Fig. 4 is a top plan View of the cover.

The drawing shows the invention as applied to an open-neck container or bottle I which may be made of any suitable type or material andis provided'with a threaded neck 2. The cover 3 is formed of moulded material having a top 4 and a depending flange 5 which is internally threaded as at 6 to engage the threaded neck f thecontainer in an air-tight joint.

On one side the cover 3 is provided with a spout 115, 1 having a pair of discharge or pouring openings each of which is formed by an inclined channel 8yterminating at its inner end in a vertical bore 9 of substantiallylargerdiameter than the connected channel 8. The channels 8 are inclined sufficiently to permit the syrup or other liquid which may remain therein to flow back into the container when the container is righted after the pouring operation. The-bores 9 are of sufliciently large diameter to prevent the syrup from clogging v the same. Atthe same time the channels 8 are of sufiiciently small diameter to discharge the small streams of syrup which are required for properly mixing the same with carbonated water. Channels 8 havinga bore of substantially A have been found. suitable for this purpose. In the form illustrated the bores Bare indiameter.

The air vent is formed in two. parts and comprises an inner channel Ill which is of small diameter to retard passage of syrup therethrough and preferablyhas a diameter smaller than that of a. drop of the syrup to bev dispensed. The inner channel l0 communicates at an angle with an outer channel II of substantially larger diameter which opens through the periphery of the cover 3 at a point diametrically opposed to the channels 8. The channel H is preferably s0 arranged that it extends substantially vertically upward when the container is tipped for pouring. The inner channel I0 is disposed a substantial 4 distance from the bores 9 of the pouring spout. The inner channel 10 forms a small sharp-edged hole in the inner surface of the cover 3. This minimizes the tendency of the syrup to cling to the inner surface of the cover and to thereby cover the air vent, as the syrup has but little tendency to cling and form drops on a surface that is hard and? smooth. The inner channel I0 is. made as small as pos sible' to provide the necessary carrying capacity not enter the air vent when the container is tipped for pouring. Any syrup that does enter the small channel I is prevented from reaching the outer surface of the cover by reason of the fact that the outer channel II is substantially larger and meets ,the inner channel at an angle. In the form shown the two channels meet at a right angle. The inner channel I0 is formed comparatively short so that any liquid which does find its way into this channelis drawn back into the container due ,to the air entering the same In the embodiment shown two discharge Chan nels 8 have been employed. It is to'be understood, however, ,that any suitable number of such channels may be incorporated in the devi'ce depending upon the size of thecover and the. particular requirements. In using ,the device for the mixing of beverages the container is preferably moved laterally above the surface of the carbonated water 'to assist in thoroughly, mixingand incorporating the syrup therewith. Inasmuch-as ,the rate of flow is comparatively uniform the quantity of syrup thus added can be readily estimated by the length of time that the pouring operation is continued. 1

It is'to be notedthat the above-described container is adapted to discharge the small streams required for properly mixing beverages and is practically dripless. Liquid remaining in the channels, 8 immediately withdraws from their outer ends andthe shape and arrangement of the air vents prevents liquid from reachingthe outside.. The air vents are also self cleans'ing whereby the tendency to'become'clogged is eliminated. Hence, expansion of air in the container, after pouring, is immediately relieved.

A specific embodiment of the invention has been described for purposes of illustration. 7 It is to be understood, however, that various modifications may bemade therein without departing from the scope and spirit ofthe invention. A spout such as "I is not necessary. The principle works well if the closure is made without a spout, with delivery channels'leading'to the upper rounded edge. In such a case the channels can be at such anangle that the vertical bore 9 is unnecessary.

It is not absolutely necessary to have channels III and'l I of different sizes, but it is better to have channel I I of liberal dimensions relative to to reduce'resistance to the passage of air. The angles between channels In and I I should be such that a spit of syrup passing through III will impinge on the wall of I I. V
