3 Claims.

`or carbonated beverages from bottles.

One of the objects of the invention is to provide a dispensing device which can be readily attached to the neck of a bottle in an air-tight and liquidtight manner and which will support and seal the bottle and permit the contents of the latter to be discharged as desired.

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Fig. l is a front elevation of our improved dispensing device with a fragment of a bottle neck attached thereto. t

Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal sectional View on the line 3-3 of Fig. 2.

Fig. 4 is a fragmentary plan view of a detail.

Referring to the drawing, 5 is a base from which rises a post 6 that has its lower end rigidly connected to the base. The post is preferably square in cross section and is rigidly connected at its upper end to a bracket 1 which supports a cup 8. An annular resilient gasket 9, preferably formed of tasteless black rubber, has its lower portion seated in the cup. This lower portion of the gasket is provided with an external annular s shoulder I which is clamped in th'e cup by means of a retaining ring I3 having external threads engaging internal threads of the cup as shown at I2. The ring is provided with holes I3a for the reception of a spanner so that the shoulder ID may be compressed when the ring is screwed into the cup.

The lower portion of the gasket is also provided with a substantially conical outlet port I4 with the smaller end of the port arranged at the lower end of the gasket, and at the upper end of this port the gasket forms an annular ledge I on which the end of the bottle neck I6 seats.

A horizontally disposed annular groove I1 is provided in the gasket immediately above the ledge I 5 and this groove receives the conventional bead I8 of the bottle neck.

The bore of the gasket, immediately above the groove is contracted as shown at I9 so that the head of the bottle in entering the gasket must (Cl. 22E-22) expand the upper portion of the latter before the bead enters the groove. As soon as this takes place the upper portion of the gasket contracts and acts to tightly grip the neck of the bottle.

In order to prevent expansion of the upper portion of the gasket after the bottle neck has been inserted into the same, a clamping ring 20 is placed about the upper portion of the gasket between the shoulder I0 and a terminal annular bead 2|. This clamping ring may be` of any suitable construction, for example, it may consist of a split ring provided at its ends with ears 22 and 23 which are drawn toward one another by means of a screw 24 and nut 25.

For the purpose of controlling the discharge of liquid through the gasket, we provide the cup with a valve structure 2l consisting of an elongated tubular member having one of its ends screwed into the cup at 28. The same end of the tubular member forms a seat for a valve head 29 connected to a stem 30 which extends through 20 the member and is provided at its outer end with a push button 3I. The valve is normally maintained in closed position and the push button in projected position by means of a coil spring 32, which surrounds the valve stem and is positioned between a shoulder 33 of the tubular member and a shoulder 34 at the inner end of the push button.

The tubular member has an internal passageway 35 communicating with the vertical passageway 36 of a discharge spout 31.

In using the device the nut of the clamping ring is loosened to permit the gasket to expand and then the neck of the bottle, after the cork has been removed, is inserted into the gasket until the end of the bottle neck contacts with the ledge I5. Then the clamping ring is tightened to hold the bottle in place and to form the necessary seal, and from that time on liquid may be discharged from the bottle each time the push button 3I is actuated.

'Ihe clamping ring which ts around the resilient gasket on the bottle neck is not intended to compress the gasket, but merely to hold it in shape, as the gasket is designed so that it is leak tight as soon as it is put on the bottle. However, to keep the bottle from being pulled out of the gasket, we employ the clamp to retain the outside diameter of the gasket. Therefore, the clamp merely holds the outside diameter of the gasket to its original dimensions, which prevents the shoulder I8 from moving out of the gasket. Obviously, our clamp forties the exterior of the gasket so that it cannot be stretched materially at its outside diameter.

of bottles comprising a supporting cup, an annular resilient gasket seated on said cup and having an external shoulder, a retaining ring interlocked with said cup and engaging the shoulder to clamp the gasket to the cup, the bore of the gasketV forming a seat for the end of a bottle neck and having an annular surface to grasp the bottle neck, and an expansible and oontractalole ring surrounding the gasket for preventing external expansion of the upper portion of the gasket and positioned to prevent disengagement of the ring and cup.

2. In combination, aV base, a post having its lower end secured to the base, a cup secured to the upper end of the post and arranged at one side of the latter, said cup having a discharge passageway at its lower end, the wall and bottom of the cup forming annular steps, an annular resilient gasket having its lower end portion seated on said steps, the gasket having an external annular shoulder intermediate its ends, a ring seated on said shoulder and detachably securing the gasket to the cup, the bore of the gasket communicating with said passageway and forming a lower horizontal seat, an intermediate horizontal groove and an upper restricted annular surface, a bottle neck grasped by the gasket and having its lower end resting on said seat, said bottle neck having an annular `beadextending -into said groove, and an adjustable clamping ring surrounding the upper end portion of the gasket for retaining the external diameter of the latter.

3. A device for use in dispensing the contents of a bottle comprising a supporting cup, an annular resilient gasket seated on said cup and extending above the latter, said gasket having an external shoulder, a retaining ring interlocked with saidvcup and engaging the shoulder to clamp the gasket to the cup, the bore of the gasket forming a seat for the end of a bottle neck and having an annular surface to grasp the bottle neck, and an expansible and contractable -ring surrounding the gasket above said ring for preventing external expansion of the upper portion of the gasket and for also preventing disengagement of the ring and cup.
