This invention is directed to an improvement in dispensing cans, and particularly to a means for pouring from the can with certainty of direction and with complete sealing against delivery in a predetermined position of the pouring element, theinvention also being directed to means for automatically controlling the air vent for the can.

In dispensing from a can or container, particularly where delivery is to a relatively restricted opening as, for example, in pouring gasoline into the tank of a car or boat, or in pouring oil into the receptacle of an automobile or boat, the ordinary spouted can is not only diificult to, handle for the pouring operation, but invariably results in delivering some portion of the contents of the can outside of the opening into which it is to be delivered.

In the use of gasoline or oil, particularly in'connection with automobiles or boats, the

spilling of the fluid'outside the receptacle for which it is designed results in a dangerous condition, owing tothe fire hazard, and hence it is of prime importance that the pouring means by which the liquid is delivered from the container to the tank or other receptacle be such as to absolutely insure delivery of all liquid into the tank or other receptacle without possibility of spilling or splashing around the mouth of the opening. Furthermore, owing at times to the inconvenient disposition of the tank or receptacle opening into which the fluid is to be poured, the position of the container to accomplish this result is so awkward or at times impossibleyto a con ventional spout as to preclude a proper fluid delivery, and this is so universal that the conventional filling equipment includes a funnel, thus at once recognizing the desire to avoid waste and the fire hazard and the practical impossibility of properly pouring from the conventional spout can into a container of the Woe eferred to. v i The primary object of the present invention, therefore. is the provision of a flexible spout leading from the can and ofs ufiicient length to permit its introduction into the inlet opening of a tank or other like receptacle,

with the flexibility of the spout readily accommodating itself to different movements of the can-necessary for the pouring operation and readily and conveniently lending it self to accommodating unusual and otherwise impossible positions of the can for pouring into tank or receptacle openings located at difiicult points of access.

In containers designed more particularly for gasoline and oil, it not infrequently happens, particularly in connection with motor boats, that a quantity of gasoline will be carried in a number of containers to be stored in the boat to renew the supply in the tank as the latter is used by the engine. The presence oi these containers, if there is any possibility of leakage of gasoline or fumes thereof, -or any possibility, in the event the containers become accidentally overturned, of the escape of the container gasoline, constitutes a continual fire hazard which has been a source of many serious accidents.

A further object of the invention, therefore, is the utilization of the flexible spout as an element for controlling a valved communication between the spout and the interior of the container to which'it is connected so that the valve establishing such communication and permitting pouring from the' container through the flexible spout is not opened until the spout is arranged in a desired pouring relation, such valve being completely closed in any other position of the flexible spout to prevent possibility of leakage, either of the fluid or the vapors therefrom.

A further object of the invention is the provision of means by which the free end of the flexible spout is substantially locked against casual displacement in a position across the body of'the can and overlying and acting as a holding element for the conventional can cap, the valve controlled by the spout being completely and entirely closed when'the free end of the spout is in the holding means, so that with the parts in this position leakage from the CELL in the event the can is "overturned, is absolutely impossible and thus full and complete protection against the ever-present fire-hazard of the conventionalcan is afforded.

In cans of this type, it is usual, when-ready to pour from he can, to vent the can to per init proper delivery of the fluid by slightly turning the cap usually employed for the filling closure. This would form an admirable vent if turned only to the proper extent, but unfortunately the turning of the cap for venting purpos s isordinarily carelessly or hurriedly done and the result is that when the can is upturned for pouring, the fluid will run out of the cap opening. It is important in connection with venting a can of this type that the vent when open be permanently such as to admit just the proper quantity of air; that the vent be permanently and preferably automatically sealed when the can is not in condition for pouring therefrom; and that the vent be automatically opened without attention on the part of the user when the parts are in relation for pouring.

Therefore, a further object of the inven tion is the provision of an automatic vent designed to be engaged by the flexible spout and serving, when the spout is in inoperative locked relation to the can top, to be automatically held in vent-closing position; the vent automatically opening as the flexible spout is raised from its locked relation to the can cap whereby when the spout is in inoperative locked relation, the vent is automatically closed and when the spout is raised from its locked relation and turned toward pouring or delivery position, the vent is automatically opened; the vent provisions being such as to insure the admission of only the exactly proper amount of air for venting purposes, that is, to permit free flow of the liquid within the can.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a broken section, partly in elevation, showing the improved can pouring means, the valve being shown in closed relation and the pouring spout in locked position.

Figure '4' is a perspective view showing the parts of the vent valve in separated relation.

The container 1 may be of any conventional form and, of course, is to be constructed in different sizes, Preferably the body 2 is constructed integrally of a single piece of metal, and the top 8 formed to lit the body finally welded to the upper end of the body to construct the container as a complete inseparable unit affording themaximum protection against leakage through seams or the like. However, in this connection it is un- (lei-stood that the invention is not particularly concerned with a can of this type but is applicable and designed for cooperation with containers however constructed and made up.

The top 3 is preferably rounded on the upper surface and centrally formed with a depending flange 4 defining an opening 5, to which is welded a threaded sleeve 6, with the threaded portion of the sleeve projecting above the top proper to cxteriorly receive the threaded skirt 7 of a cap 8, which cap has an upstanding, preferably angular, projection 9 to facilitate application and removal of the cap. A sealing disk 10 may be interposed between the flange of the cap and the upper edge of the sleeve 6, with said upper edge inwardly deflected, as at 11, to afford an effective sealing support for the perforated disk 10 so that on the application of the cap, leakage through the opening 5 is absolutely prevented.

The pouring element for the can, with which pouring element the invention is more particularly concerned, involves a valve member forming in itself a rigid part of the pourmg element and a flexible spout connected with the valve member, the valve member cooperating with a valve element fixed to and forming a rigid part of the can top 3. As constructed, the valve element includes a hollow, cylindrical body 12 closed at the bottom, as at 13, and open at the top. This valve element is sealed, as by welding, in an opening 14; in the top 3 preferably adjacent the side edge thereof, the body 12 being formed inwardly of the top and immediately adjacent the curved upper wall thereof with an open- 111g 15 which opens toward the center of the container, that is, away from the edge adacent which the body 12 is secured.

The body 12 is rigidly secured to the top, as by welding or the like, and is further supported by a brace 16 welded to the interior of the top inwardly of the body, as at 17, and extended downwardly to underlie the closed end 13 of the body 12. The brace member in that portion underlying the body is preferably dished, as at 18, the dished portion more or less snugly fitting the closed end of the body 12 and serving to materially support the body against endwise strains thereon which might otherwise tend to break it from its connection with the top.

The spout proper comprises a valve element 19 and a flexible spout extension 20. The Valve element 19 comprises a rigid elbow section 21, the exterior diameter of which is somewhat less than the interior diameter of the valve element body 12. The valve element 19-is open at the lower end and such lower end is designed to seat within the valve body 12, with the lower end of the valve element bearing against the closed end 13 of the body. The valve element is formed in any appropri ate-manner with an exterior annular flange 22 and a cap section 23 of an interior diameter to snugly fit over the upper end of the body 12. The cap section has an upper, inwardly extending flange 24 to overlie the flange 22 of the valve element 19. Thus, with the elbow section of the valve element in place in the body 12, the cap may be applied to fit over the flange of the elbow section and overlie the upper end of the body 12. In this posi-' tion, the juncture between the cap 23 and the body 12 .is sealed and the cap is secured in place, as by welding or the like, whereby the elbow element of the spout is held against independent axial movement with respect to the body 12 of the valve element, though freely rotatable in said body 12, as will be obvious.

The elbow section 21 of the spout is formed in the diametric plane of the opening 15 of the body 12 with a corresponding opening 25, and this opening is diametrically opposite the direction of projection of the upper, laterally deflected end 26 of the elbow section of the valve element 19. WVith this arrangement, when the spout is turned so that the upper section 26 projects toward the cap 8 of the container, the opening in the valve proper is diametrically opposite-the opening 15 in the valve element body 12. A

sealing section 27, preferably of cork, though obviously of other appropriate materials, if desired, is arranged between the wall of the valve proper and the interior surface of'the body 12 of the valve element, this sealing lining being, of course, formed with an opening 28 which registers at all times with the opening 15. The sealing element 27 serves as an effective non-leaking seal between the valve proper and the valve elementjbody and prevents possibility of'the escape of any fluid through the opening 15 when the opening 25 is not in registry therewith.

The remaining flexible section 20 of the spout is shown of conventional flexible me-' tallic hose section terminating in a rigid sleeve section 29. Diametrically opposite the valve body the top 3 is provided with an upstanding locking element 30 having spaced spring jaws 31 between which the flexible section of the spout is adapted to'be forced when the spout is not desired for use, the spring gripping effect of the jaws being sufficient to hold the spout in this posi-' tion against possibility of casual displacement and such as to require an appreciable pulling action on the free end ofthe spout to disconnect the same.

The automatic vent forming part of this invention is preferably applied to the upotherwise rigidly secured to the cap. This casing 32, which is fully open at the upper and lower ends, is circumferentially enlarged interiorly, as at 33,'the enlargement -form ing an abrupt annular shoulder 34. The wall of the casing near the lower open end is formed with a vent inlet 35 in the form of an elongated slot arranged parallel to the lower edge of the casing and extending circumferentially of the casing wall. vent inlet, as will later appear, determines the admission of the air for venting the can and it is of the utmost importance that the area of this vent inlet be accurately designed with a view to admitting just the desired quantity of air for properly venting the can. If the area of this opening is too small, improper air admission follows and improper or imperfect delivery of the fluid from the pouring about results. If the opening is too This large, there is a decided tendency of inversion of the can for pouring to permit some of the liquid contents of the can to flow out through the vent opening, as will be understood. Therefore, it is to be understood that this vent opening is of elongated form near the lower edge of the casing and arranged circumferentially of the casing, with -its major axis parallel to the lower edge of the casing, with the length and breadth of this slot accurately determined to admit the proper quantity of air for venting the can. and thus avoid the obvious disadvantages of too little air or too much air being vented.

' Vertically sliding in the casing is a cutoil or plunger 36. The upper portion of the plunger as a whole is open throughout its length, the stem being open .at the upper end to serve as an air-admitting opening and the lower end of the valve section 38 being also open. As a result of the formation of the plunger and of the fact that the longitudinal opening in the stem is of materially less.

diameter than the interior opening of the valve section, the interior of the plunger is formed to provide an abrupt interior shoulder 39 at the juncture of the stem and valve portion.

A coil spring 40 is loosely placed withinthe valve section, with the upper end bearing against the shoulder 39, and a cap terminal 41 arranged for threaded connection with the exterior of the lowerend of the casing is designed, when in place, to exert pressure on the lower end of the spring l0 and through the pressure compel the plunger to normally occupy a position at its upper limit of movement, that is, in a position in which the upper end of the valve section 88 engages the shoulder 34 in the sleeve member. This is the normal or venting position of the valve structure, and the axial length of the valve section 38 of the plunger is such that when the plunger is in this normal venting position, the lower edge of the valve section 88 is immediately above the vent inlet slot 35.

As the plunger is of hollow form, that is, has a longitudinal bore open at-the top and bottom, it is apparent that when the plunger is in normal or operative position, with the lower edge of the valve section 38 above the vent inlet slot 85, air will pass freely through the plunger from beyond the can and to the interior of the can through the slot, any other escape of the air to the interior of the can being prevented by the cap 41. The plunger is of such length that when in normal position, the upper end projects some distance above the upper end of the casing and this projecting end of the plunger is provided with a disk member 42 for convenience in controlling the plunger, it being understood, of course, that the disk member surrounds the open upper end of the plunger and does not cover the axial bore thereof.

In the described mounting of the venting means, the disk 42 directly underlies the posi tion occupied by the flexible spout extension 20 and the extent of projection of the plunger, and thereby the disk above the cap section 9 under the influence of the spring 40, is such that when the spout extension 20 is forced to the locking position, that is, between' the spring jaws 31, this spout extension. 20 will engage and depress diskmember 42, and thereby the plunger 36, against the influence of the spring 40. The relation of the parts is such that in this depressed movement of the plunger incident to moving the spout extension to locking position, the lower edge of the valve section 38 of the plunger is carried past and below the vent inlet slot 35 in the casing, and as this section of the plunger has a substantially sealing interfit with the corresponding section of the casing, it is apparent that the vent inlet 35 is thus completely closed by the valve section of the plunger. This is the inoperative position of the venting mechanism in which the admission of air to the interior ofthe can is completely prevented.

It is apparent that the operation of the venting mechanism, and more particularlythe venting plunger, is entirely automatic so far as any attention on the part of the user is concerned. That is to say, when the spout is turned to an inoperative position and the flexible spout extension 20 forced down into locking cooperation with the top of the can,

such movement of the spout extension automatically depresses the plunger of the venting mechanism and thereby at once cuts off admission of air to the interior of the can. In operating the parts to deliver liquid from the can, the spout extension 20 is first raised from the locking lips 31 and as it is moved to a position free of the lips to permit it being turned to delivery position, the spring 4E0 of the venting mechanism automatically oper- 1 ates to move the plunger to a position to raise the lower edge of the valve section 38 above the vent inlet slot 35, and the interior of the can is open to the admission of air through the axial bore of the plunger, as will be evident.

Thus the venting mechanism is entirely automatic in operatiomfor the mere placing of the delivery spout in the desired inoperative position cuts off the air admission to the interior of the can, While the mere movement of the flexible section of the spout for oper-- ating the spout to delivery position automatically vents the can. Again, it is to be repeated thatthe volume of incoming air for venting purposes is controlled entirely by the size of the vent inlet slot 35 and this must be proportioned to admit only that volume of air which will provide the proper vent and at the same time prevent any possibility of the liquid in the interior of the can from escaping in the event the can is inverted during the pouring operation.

The venting mechanism as a whole is carried by the filling cap, which is a rather important feature from the manufacturing standpoint, in that if for any reason the venting mechanism should become inoperative or out of order, it is extremely convenient to 1'6." new such mechanism merely by applying a new cap with the mechanism thereon. The can body or pouring parts are not disturbed under these conditions, and the renewal of the entire venting mechanism is immediate incident to the replacement of a new cap. Furthermore, in filling the can, under which circumstances the cap 8 is entirely removed, the venting mechanism is protected against in jury or derangement during the filling of the can and becomes immediately available for proper functioning by the mere replacement of the cap proper. The interior of the venting mechanism. is accessible by removing the cap proper and then removing the spring holding cap terminal l1.

It is, of course, apparent that with the improved venting mechanism described, the filling cap 8 remains at all times in sealing cooperation with the filling opening, and thus so far as this cap is concerned, an absolute sealing, non-leaking relation with the can is assured, as there is no necessity for adjusting this filling cap for venting or other purposes nism operates in the vertical axisof the can or container and moves vertically in both operative and inoperative movements. This materially simplifies the operation and avoids undue wear on the parts. Furthermore, the disk member 42 is beveled or slopes downwardly in all directions from its connection with the upper end of the plunger, that is, the outer circumferential edge of the disk member is on a plane lower than the central portion thereof. This avoids breakage of the parts and insures effective cooperation of the venting mechanism when the spout is moved to inoperative position, for it the spout extension 20 is somewhat depressed during this movement it will, by reason of the downward sloping edge of the disk member, ride over the disk member and depress the plunger. A material latitude in the position of the flexible spout section 20 in the movement of the spout to inoperative position is thus permitted without liability of breakage of the valve mechanism and without possibility of nonoperation of the venting mechanism. I

When the parts are in normal POSltlOIlftlS indicated in Figure 1, with the free end of the flexible section of the spout within the locking means 30, it is apparent that the openings 15 and 25 are out of registry. Therefore, it is impossible to deliver the contents of the can through the spout. Owing to the rather rigid gripping of the spout in the locking means, any ordinary overturning of the can as a whole or tilting thereof accidentally or otherwise will not dislodge the spout from the locking means, and as long as the spout remains in the locking means, there is no possibility of fluid delivery from the can through the spout. When desiring to deliver from the can, the flexible section of the spout is removed from the locking means and the spout as a whole, including the elbow section or valve proper, is turned to a position subsantially through 180 from its normal position, that is, to the position illustrated more particularly in Figure 2. v

In this position, the openings 25, 28 and 15 are in registry and a free outlet is provided for the fluid from the interior of the can through the spout. In this position, .the lateral section 26 of the elbow element of the valve proper is wholly beyond the side wall of the can so that the flexible section 20 of the spout is at all times well beyond the side wall of the can. Thus, in delivering from the spout, the flexible section may be turned directly downwardly, outwardly, laterally in 7 either direction, or even upwardly, for the rigid disposition of the elbow section with respect to the can proper insures at all times a fluid outlet, while the disposition of the flexible section 20 to accommodate that section to the openinginto which the fluid is to be delivered iswholly unimportant for the purpose of the pouring operation. Thus, the

flexible section of the spout will permit delivery from the can in practically any and-all positions in which it is possible to permit the fluid to flow. outwardly from the can, or in other words the nozzle end 29 of the flexible section of the spout may be in practically any position within the limits of the flexibility and length of the spout section 20 and yetcomplete and adequate delivery from the can may be readily and easily accomplished.

Itis to be particularly noted that, as shown and as preferred, a relative limited movement of the plunger 36 is sufiicient to close the vent 35, that is, the closing function of the plunger, so far asthe vent is concerned, follows a comparatively slight movement of the plunger, although the plunger is capable of moving a greater distance in the same direction, though in no instance capable of moving to such an extent as will open the vent 35 in any but the uppermost position of the plunger. This capability of the plunger to close the vent under a comparatively small movement is important, for it provides for the closing of the vent, that is, the closing of the air admissionto the canv under a comparatively light pressure of the flexible section of the spout or in the event the spout is slightly oiiset to engage the valve disk at the edge rather than I the top. I

In either of these positions of the flexible section of the spout, the valve will be moved to close the vent when the spout is in inoperative position as described, and even if under these circumstances the spout should be moved to a fully depressed position or to a position engaging the highest point of the plunger disk 42, there isstill suflicient excess movement possible in the plunger to acco1n modate this position of the flexible portionof the spout without liability of breakage of the parts. Thus, the valve will be eflectively operated to cut ofl the air vent even under a relative minimum movement thereof incident to the cooperation of the spout with the lowered edge of the plunger disk or the curved position of the flexible spout which would not fully depress the valve when the spout was moved to an inoperative position.

Thus, the valve responds to different cooperations of the spout with the valve proper and under each of such cooperations insures afully closed valve.
