1 Claim. 1

The invention relates to improvements in dispensing devices and more particularly to the novel construction and association of parts comprising an easily mounted, inexpensive dispensing syphon.

The object of the invention is to provide a dispensing syphon of the character referred to with novel means for attaching it to the neck of a container.

Another object of the invention is to provide a novel sleeve and ring structure for mounting a dispensing syphon on the neck of a container.

Another object is to provide a dispensing syphon with novel valve means.

Another object is to provide a dispensing syphon with novel means adapting it to be easily and quickly attached to and hermetically sealed over the pouring mouth of a container.

Other and further objects of the present invention will be apparent from the following description and claim, and are illustrated in the accompanying drawing which, by way or illustration, shows an exemplary embodiment and the principle thereof. Other embodiments of the invention embodying the same principles may be used, and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claim.

In the drawing;

Figure 1 is a fragmentary sectional view of a container showing a dispensing syphon, embodying features of the present invention, afiixed thereto.

Figure 2 is a fragmentary side elevational view of the dispensing syphon, taken substantially along line 2-2 of Figure 1.

Figure 3 is a horizontal sectional detail view taken substantially along line 3-45 of Figure 1.

Figure 4 is a vertical central sectional view of a dispensing syphon embodying modified features of construction, showing parts thereof in elevation.

The dispensing syphon embodying the features of the present invention and illustrated in the accompanying drawing is of the character adapted to be detachably secured over the pouring mouth of a container, such as a bottle. As shown, the container includes a neck H having an externally beaded periphery surrounding its pouring mouth and provided, below said beaded periphery, with an external bead l2. The dispensing syphon preferably is formed from sheet material suitably drawn into the required con be understood, however, that it may be fabricated from any other suitable material in any' other conventional manner.

The dispensing syphon consists, primarily, of

a pair of separable elements consisting of a cupshaped body is and a sleeve Hi. The sleeve I4 is .1 cylindrical in shape and it includes an internal flange i5 suitably formed on its lower edge. A pair of diametrically opposed bayonet slots 6- are provided in the cylindrical side wall thereof,:

each slot opening on the upper edge of the sleeve for purposes to be understood as the description- The inside diameter of the flange l5.

proceeds. is sufficiently large as to permit the sleeve to. be

r slipped loosely over the bead 12 of the neck Ii.

when the syphon is to be mounted thereon. The

flange i5 is adaptedto have seated thereon, a.

split retaining ring or collar ll which has an in- I ternal diameter of such size as to snugly embrace. the neck of the container below the bead l2.

The body is is formed substantially cupshaped with its circular wall it depending down-v wardly from the top Wall !9 thereof and is of such diameter as to have a free sliding fit within the circumferential sleeve it. A tubular stem 2!, formed axially on and extending upwardly.

from the wall is, is adapted to contain manually operable valve means including an operating cap. 22. The cap 22 is, as illustrated, telescopically fitted over the open upper end of the tubular stem; 2| and it is provided with a depending rod 23, the lower end of which carries a valve element 24. The valve element 2% is arranged to cooperate with a circular valve seat provided on the lower end of a sleeve 25 firmly secured within and depending from the lower end of the tubular stem 2!.

The valve normally is retained in closed position as by means of a spring 26 interposed between the cap 22 and an inwardly struck circumferential bead'2'l formed in the tubular stem' 2!. A spout 28 extends outwardly from and communicates with the tubular member 2!. It should be quite evident at this time that when the valve is closed communication between the interior of the container and the spout 28 is prevented. However, when the cap 22 is depressed manually, said valve is moved into open position to thereby allow the container contents to flow upwardly through the sleeve 25, tubular stem 2i and out through the spout 28.

Movement of the container contents outwardly through the spout 28, when the valve is open, is

ngurations or from tubular material, It should 55 obtained by reason of the inherent pressure within the container. This pressure is present in all packaged carbonated beverages or the like.

Obviously, means must be provided in the dispensing syphon, or in association therewith, to prevent the escape of pressure from within the container. Accordingly, the inverted cup-shaped body I3 is provided, on the inside surface of its wall 19, with a circular Washer, or gasket, 29, preferably fabricated from rubber or other suitable compressible material of a kind not susceptible to rapid deterioration resulting from contact with the contents. The washer or annulus 29 has, formed integral therewith, a downwardly extending tube 3| which terminates with its open end spaced above the bottom of the container.

The compressible washer 29 is adapted to afford an hermetic seal between the inverted cupshaped top wall l9 and the end of the container neck. It is, therefore, essential that said washer 29 be compressed when the dispensing syphon is mounted in place. Such compression of the washer 29 is accomplished automatically upon mounting the body 13 on the container. As best illustrated in Figure 2, the body l3 has a pair of outwardly projecting diametrically opposed pins 32, each of which is adapted to cooperate with one of the bayonet slots I6 in sleeve !4. Inasmuch as the portions of said slots 46 extending in a circumferential direction in the sleeve [4 are inclined downwardly slightly towards their terminal ends, engagement of the pins 32 therewith and subsequent rotation of the body [3 draws said body downwardly to compress the washer 29. Such engagement and down drawing of the cup shaped body I3 also tends to draw the sleeve 14 upwardly to thereby carry the split ring ll into close engagement with the container neck bead l2. In this manner the container is hermetically sealed and inadvertent separation of the dispensing syphon from the container neck is prevented. It might be noted that the pins 32flextend outwardly of the sleeve l4 so as to afford finger engaging means when rotating the body.

Referring to the structure disclosed in Figure 4, the dispensing syphon body I3 is substantially like that discussed hereinabove and is adopted to cooperate with a retaining sleeve of the kind shown in Figure 1. Accordingly, like numbers will be used to identify corresponding parts. The Figure 4 structure differs, however, from that previously described in the construction of the valve embodied therein.

As shown, the valve includes the depressible cap 22 and rod 26. In this instance, however, the lower end of the rod 26 carries a plunger 33 which has a slide fit in a valve element 34. The valve element 34 is in the form of a nipple firmly secured at its upper end in the lower end of the tubular portion 2! and of such length that the plunger 33 remains within its end limits irrespective of whether or not the valve plunger is elevated or depressed. When in the elevated position illustrated, the plunger 33 effectively stops the flow of fluid from the interior of the container to the spout 28. However, upon depression of the cap 22, the plunger 33 is carried into a position below radial ports 35 provided in the wall of the nipple 34. The fluid contents of the container upon which the dispensing syphon is mounted is then free to flow through the ports 35 and out of the spout.

Although exemplary forms of the invention have been disclosed in the accompanying drawing and described in detail in the foregoing specification it should be understood that the invention is capable of embodying a wide variety of modifications in detail construction without departing from the spirit of the invention or the scope of the appended claim.

I claim:

A dispensing syphon adapted to be fitted over the pouring neck of an externally beaded container comprising a sleeve adapted to be fitted over said beaded. neck, asplit ring insert in said sleeve adapted to engage beneath the bead to prevent withdrawal of the sleeve, an inverted cupshaped body fitted over the neck and into the sleeve, means detachably connecting the body and sleeve, a gasket within the body adapted to overlie the pouring opening when the body and sleeve are secured together, said gasket having a tubular portion depending therefrom into the container and open at its lower end, a tubular stem integral with and communicating with the interior of said body and extending outwardly from the body end wall, a spout on and communicating with the interior of the stem, a sleeve in the body anchored at one end in the stem and having a valve seat at its other end which projects into the body, and a valve element cooperating with the seat, said valve element being movable to permit the contents of the container to be withdrawn through the tubular portion and dispensed through the spout.
