Feb. 18, 1936.. G. J. MALONEY BEVERAGE DISPENSING BOTTLE Original Filed Oct. 28, 1931 NW ON Patented Feb. 18, 1936 UNITED STATES BEVERAGE DISPENSING BOTTLE George J. Maloney, Long Beach, Calif.
Application October 28, 1931, Serial No. 571.533 Renewed September 24, 1934 7 Claims. (Cl. 221-77) My invention relates to beverage dispensing bottles and more particularly to a bottle in which the contents of the bottle may be placed under pressure by a pump carried by a removable stopper for the bottle and discharged through a spout by opening a valve also supported by the stopper.
A general object of the invention is to provide a novel arrangement of the pump and discharge mechanism in a bottle of the above character which arrangement provides for simplicity and compactness of the parts, convenience in manipulation thereof, and enclosure of such parts by a removable cap for the bottle.
The invention also resides in the novel construction and arrangement of the parts of the valve by which the structure as a whole is simplifled and dripping of the beverage from the spout is effectually prevented.
A further object is to provide a new and im proved packing forming an eifective seal between the stopper and the bottle neck.
Other objects and advantages of the invention will become apparent from the following detailed description taken in connection with the accompanying drawing, in which Figure 1 is a vertical sectional view of a beverage container embodying the features of the present invention.
Fig. 2 is a side elevational view of the bottle with the cap thereof shown in section.
Referring now to the drawing, 3 indicates the metallic tubular body of the bottle closed at its lower end by a head 4 and having an annular ring 5 secured to its upper end and defining an internally threaded opening which is of relatively large diameter so as to facilitate cleaning of the bottle and permit the pump and valve mechanism to be incorporated in the stopper. The latter is in the form of a casting 6 having a flange l at its lower end formed with external threads adapted to be screwed into the head 5. In the present instance the end of the flange l is formed with an annular rib 8 which, when 45 the stopper is screwed into place, engages a gasket 3 of soft material such as rubber seated in an upwardly opening annular pocket defined by an internal flange It on the ring 5 and an upturned rib II on the flange. The gasket is 50 thus compressed and forced laterally against the sides of its seat so as to form an effective seal under all conditions in spite of looseness at the threads, due to ordinary manufacturing inaccuracies. By locating the gasket below the 55 threads in the head I, the threads are always dry when the stopper is in place thereby contributing to cleanliness of the bottle.
Formed on diametrically opposite sides of the casting 6 are two parallel vertical passageways i2 and I3, the former being oifset laterally from g the axis of the container 3 and constituting the cylinder of the pump in which is disposed a piston H which is rigid with the lower end of a stem I5. The upper end of the stem projects through an apertured disk It screw threaded into 10 the upper end of the cylinder.
When the pump is actuated by reciprocating a knob or handle ll on the upper end of the stem l5, air under presure is forced through an opening I8 in the closed end of the cylinder forcing 15 a valve member 20 downwardly away from its seat and against the action of a spring 2| acting upwardly between the valve and an apertured disk 22. The latter threads into the lower end of a flange 23 which defines the valve casing and 20 guides the valve stem; The contents of the bottle may be placed under the desired pressure by a few reciprocations of the pump handle.
The passageway l3 communicates with the lower end of the container through a vertical tube 25 24 rigid at its upper end with a bushing 25 threading into the lower end of the cylindrical passage I3 at its upper end, a seat 26 is formed for a valve member 21 which is urged toward closed position by a compression spring 28 seated in 30 the bushing 25. The stem 29 of the valve projects upwardly through a smaller vertical passageway 30 and bears against the under side of a diaphragm 3| preferably formed of rubber with its peripheral edge forced against a shoulder 35 32 by a clamping disk 33 thereby forming an absolute seal at the upper end of the valve passageway.
Projecting laterally from the casting 6 on the side thereof diametrically opposite from the pump 40 is a lug 34 which is drilled to form an orifice communicating with the passage 30 between the diaphragm and the valve disk 21 and adapted to direct a stream of the fluid laterally of the stopper and in a slightly downwardly inclined direction. The hollow lug thus forms the nozzle or spout which is spaced above the open end of the container a distance suflicient to enable a cup or other receptacle to be filled conveniently when held in a horizontal position adjacent the upper end of the container.
The discharge valve is arranged to be opened by applying downward pressure on the head of a button 35 which projects through and is guided for limited vertical movement in the disk 23 with its lower end bearing against the upper surface of the diaphragm in alinement with the valve stem 15. With the valye thus opened, the liquid contents of the bottle, if under pressure, flows up through the tube 24, around the valve disk 21 through the passageway 30, being discharged from the nozzle laterally and slightly downward.
By arranging the valve so as to be opened by application of downward pressure to the button 35, it will be observed that the contents of the bottle may be dispensed conveniently and without danger of tipping the bottle over when it is resting on a supporting surface. Thus, the receptacle for catching the contents may be held in one hand while the valve is opened by the other hand. Preferably, the head of the button 3' is disposed within an upwardly opening pocket defined by a flange 36 which thereby protects the valve against unintentional opening.
Upon release of the button I! and seating oi the valve member 21, it will be apparent that the passageway Ill and the noule 34 will remain filled with liquid but dripping of the latter from the nozzle will be avoided effectually owing to the absolute seal formed by the diaphragm ll which causes the entrapped liquid to be held in suspension by an atmospheric pressure. With such a packless seal for the valve, there is no danger of the valve binding or sticking in partially open position.
A sheet metal cap 31, which may be used as a.
receptacle for the beverage discharged from the bottle, is intended to be carried by the bottle in inverted position so as to constitute a protective casing for the parts of the discharging apparatus. To this end, the casting i is formed with an annular shoulder 38 over which the open end of the cap 31 is adapted to flt snugly being fastened thereto by a bayonet connection 39. By thus securing the cap to the stopper rather than to the ring 5, the same cap may be used on bottles of difierent capacities. It will be apparent that the use of a cap regular in shape and of a diameter substantially less than that of the bottle body, is made possible by the particular construction and arrangement of the discharge-valve and pump and the construction of the discharge nozzle, none of the parts of which project outwardly beyond the maximum diameter of the stopper. Thus, with the arrangement above described, the parts of the pump and valve may be made large enough to facilitate convenient manufacture and at the same time are compactly arranged. I
From the foregoing it will be apparent that I have provided a pressure bottle which is simple and inexpensive to construct, which is neat and attractive in appearance, which is convenient to operate, and which provides for a high degree of cleanliness in carrying and dispensing beverages.
