8 Claims.

This invention relates to certain new and useful improvements in lling and dispensing spouts and more particularly to dispensing receptacles of the non-rellable type. It is particularly adapted for use with a standard quart size bottle for containing a standard brand of oil or other liquid.

One object of this invention is to prevent the substitution of an inferior grade of oil for the standard brand purported to be dispensed from the glass bottle.

Another object oi this invention is a gravity operated dispensing device which cannot be utilized for refilling except when brought into proper co-operative registry with a predetermined form of lling nozzle connected to the proper lling source.

Another object of this invention is a lling and dispensing spout employing one common orifice for receiving and discharging the dispensed liquid. Other objects will appear from the detailed description.

In the drawings comprising two sheets of 'l0 figures numbered Figs. 1 to 10 inclusive one embodiment of the invention is illustrated.

Fig. 10 is a vertical sectional view of the spout and lling nozzle in co-operative registry.

The bottle lig, a portion whereof only is shown in Figs. 1, 3, 4 and 6, is a standard quart size bottle such as is commonly used in gasoline filling 'stations for containing a standard brand of oil. The standard quart size glass bottle is provided with a neck having a screw thread 5t molded therein. The frusto-conical spout Ill may have the trade-mark and/or grade-mark or' other identifying characteristic (not shown) of the distributing company and/ or its product cast, molded, or otherwise impressed, in the wall of the spout Iii, to apprise the customer of the brand oi the oil purchased.

The frusto-conical spout it is provided with a tubular extension l l constituting an orifice for the free passage of the oil or other liquid to be dispensed. At its base spout l is provided with an outwardly extending lateral flange having a downwardly extending collar I3 provided with an internal screw thread lli for threaded engagement with the screw thread 5@ of the bottle neck. The spout I6 is thus designed to be screwed into place upon the neck of any standard quart'size glass bottle. To prevent the spout from being removed from the bottle the bottom flange of collar i3 is drilled to receive a press-tted steel ball 5! (or pin) which will obstruct the free pas-4 sage oi the screw thread E@ oi the bottle in the screw thread Hl of the cap when the spout IS is rotated relative to the bottle Q9 in a direction to unscrew the same.

Positioned within the truste-conical spout lf3 is a valve mechanism 24 consisting of an internally and externally rabbeted seating ring 25 substantially Z shaped vin cross-section. This seating ring is designed to rest upon the inwardly projecting seat formed by the junction between the laterally projecting flange and the downwardly extending collar I3 of the spout lil. The channel formed in the underside of the seating ring 25 constitutes an annular guide-way for the gasket which may be made of any suitable material such as leather, rubber or of metal as preferred. The channel formed in the upper face oi the seating ring 25 serves as a valve seat for the shutters M-ll which are normally held seated against said valve seat under tension oi the spring l1 (Figs. 1, 2 and '7). The seating ring 25 is reinforced with the web 26 whereon spring il is anchored as at 46. Seating ring 25 is also recessed as at Zl-Zl (Fig. 7) to accommodate the anchored ends lili-tl of the shutters M-M. Certain of the anchoring ends fifi-ill are each provided with an ear-like extension l5 for receiving the free ends of the spring lll.

Secured to the underside of web 26 is an inlet valve mechanism consisting of a cylindrical cup 28 having a plurality of apertures 29 therein defining ports and a bottom port lill. A valve stern 3l is connected with cylindrical c up 28 in any suitable manner as by a screw thread (Fig. 1), and communication between bore illu, of valve stem 3l and cylindrical cup 28 is normally prevented by a metal ball 30 which is normally seated upon the end of valve stem 3| under tension of coiled spring 39. The upper end of valve stem 3i is provided with one or more ports 34, said ports being normally closed by the sleeve 33 which is slidably movable relative to valve stem 3| to open and close ports 34. Sleeve 33 normally closes ports 34 under` the iniuence of coiled spring 35 pressing against ilexible washer 38 which is retained in position by the collar 32. The limit of upward movementl of sleeve 33 is determined by hook 36 which is secured to sleeve 33 by a rivet 3l and which engages the shoulder defined by the underside of collar 32 against the action of coiled spring 35.

The wall I2 of the spout IG is heavily reinforced at I6, and said reinforcement being vertically drilled from above and below to provide parallel chambers which are then inter-connected by a plurality of horizontal passages I8 and I9. An elbow tube 22 is connected tothe inner end of passage-way I9 and passes downward through a suitable opening in web 26 into the bottle 49. In this manner bottle 49 is vented to atmosphere under control of a gravity operated ball 2| which is normally seated soas to close the port between chamber 29 and passage-way I9. The outer end of chamber 20 is plugged as at 9 and direct communication between chamber 20 and atmosphere is cut .off by the tubular member 23 which is press-iitted into chamber Il so as to seal the mouths of passage-Ways I8 and I9, the tip of tubular member 23 being bevelled to allow intercommunication between chamber I 'I and passa-ge-way I3, so that air can only be admitted to, or expelled from bottle 49 by way of elbow tube 22, port normally closed by gravity operated ball 2 I, chamber 29, passage-way I8, chamber I'I and tubular member 23 downward to atmosphere.

Thus it will be observed that no liquid can be admitted into bottle 49 except by way of bore SIa and ports 34. Any liquid poured through orince II will encounter shutters 5I-4I and the weight of the liquid will only tend to form a more secure seal between L shaped flanges 42 of the shutters 4| and their co-acting valve seats 48 (Fig. 3). Any attempt to force the liquid into the bottle 49 by way of elbow tube 22 will be prevented by the ball 2 I, and should the bottle be turned so as to unseat the ball 2|, the entrance of the liquid into the bottle 49 would compress the air in the bottle thereby lifting the shutters 4| and causing some of the liquid to escape. The L shaped flanges upon shutters 4| are snugly tted in the rabbeted channel of valve seat 48 to prevent lifting of the shutters 4| by the insertion of a hook like implement into the orice I I.

The bottle is designed to be filled only when the spout IB is brought into proper co-operative registry with a nozzle 53 (Fig. 8) connected with the genuine source of liquid supply. Nozzle 58 consists of a tubular member 54 having an inwardly projecting lateral flange 6I constituting a valve seat for a metal ball 62. The tubular member S5 is slightly smaller in diameter than the internal diameter of the orifice II, while the opening in said tubular member normally closed by the ball 62, is slightly larger in diameter than the end of the valve stem 3| so that when the nozzle 58 is inserted in the orice II in correct registry therewith the tubular member S0 engages sleeve 33 and slides the same downward to uncover the ports 34 thereby connecting bore 3 Ia of valve sternY 3| with the bore o-f tubular member 6|). The collar of spout I 9 is provided with a plurality of projections I5 for engaging within a plurality of key-ways 53 (Fig. 8) adapted for co-operative registry therewith. Tubular member 6|! is in turn slidably supported in a sleeve 55 forming an extension of a nipple 52. Sleeve 55 5 and tubular member 60 are keyed together by a spline 64 slidable in a guide-way 5'I to retain said members in position to insure correct alignment of ports 65 and 54 (Fig. 8). Sleeve 55 is capped with a screw cap 63, and coiled spring 6l acts 10 against an annular shoulder formed in tubular member 6D to normally prevent registry of the ports 65 and 54 and to seal the mouth of the latter against the wall of tubular member 60. Nipple 52 is internally threaded as at 53 to: con- 15 nect with asource of oil supply (not shown).

To refill an empty bottle, the operation is as follows: Orifice II of spout I0 is brought into cci-operation with nozzle 58 with projections I5 of spout I0 and recesses 33 of the nozzle in co- 20 operative registry. Bo-ttle 49 is then forced upwards causing the end of sleeve 33 to engage the end of tubular member 69. By applying upward pressure to bottle 49 sleeve 33 is caused to slide relative to valve stem 3| against the tension ci' 25 coiled spring 35 to uncover ports 34, while at the same time tubular member 65 slides relative to sleeve 55 against the increased tension of coiled spring 61| to bring ports 65 and 54 into registry. The outer end of valve stem 3| unseats metal ball 30 52 thereby establishing a passage-way between the bore 3Ia of the valve stem 3| and port 54 of nipple 52 by Way of the bore of tubular` member 54 and port 55. The oil or other liquid now flows from the source of supply by way of nipple 52, 35 ports 54 and 65, bore of tubular member 6|), ports 34 and bore Sla, of valve stem 3| (see Fig. 10), and the pressure of the oil overcomes the tension of coiled spring 39 to unseat metal ball 39 and the oil now flo-ws through the ports 29 and 4|) into 40 bottle 4S until the desired level is reached when the attendant releases bottle 49 whereupon the telescopic expansion of tubular member 60 in sleeve 55 immediately seals ports 54 and 65, to shut off any further flow of the oil from the 45 source of supply. As soon as the pressure of the oil is removed, coiled spring 39 forces the metal ball 30 against the mouth of the valve stem 3| thereby retaining a column of oil in the valve stern. 50 As the oil flows into the bottle 49 the air is forced upwards into the tubular elbow 22 thereby lifting ball 2i from its seat to permit the escape of the air to atmosphere by way o-f chamber 20, passage-way I8 and tubular member 23. The 55 bottle being now filled with oil to proper capacity,

a suitable spring cap I3 (Fig. 1) may be snapped over the oriice II tol exclude foreign matter.

When it is desired to dispense the contents o-f bottle 49 the orice II of spout I is brought 60 into registry with the mouth of the container to be lled at which time the spout will be downwardly inclined. The weight of the oil will now rest upon the shutters 4| which will open outwards (Fig. 6) against the pressure of spring 41 65 permitting the contents of the bottle to flow through the ports thus uncovered into the frustoconical chamber of spo-ut I0 thence by way of orice into the container to be iilled. While the bottle is thus turned upside down ball 2| (Fig. 1) will fall under the influence of gravity against the plug 9 thereby connecting the bottle to atmosphere; ball valve 2| now functions asa compensating valve to permit air to enter and u replace the oil. The metal ball 30 will remain seated against the mouth of valve stem 3| under the tension of coiled spring 39, and the sleeve 33 will likewise continue to seal port 34 so that the column of oil contained in bore 3Ia, of valve stem 3| will not be affected.

It should be observed that this improved filling and dispensing spout employs o-ne common orifice for both filling and dispensing, and is designed for use with a standard quart size glass bottle having the regulation screw threaded neck so that this improved filling and dispensing spout can be used in conjunction with existing bottle equipment which is a great saving to the company Whose product is to be dispensed because it eliminates the necessity of junking the existing equipment and of substituting hundreds of thousands of special containers therefor.
