Application May 12, 1933. Serial No. 670,780 4' Claims. (01. 221-'2 8) This invention relates to a container designed primarily for dispensing lubricant although it is to be understood that it canvbe used for dis pensing other fluids.

It is an object of the invention to provide a novel form of spout for permanent attachment to the outlet end of a container; there being arranged within the spout a novel arrangement of bafies and valves whereby the fluid in the container can be dispensed through the spout but cannot be poured through the spout back into the container. a a

A further object is to provide the spout with a special inlet through'whioh the container can be filled or refilled provided a special coupling means is used in connection therewith.

With the foregoing and other objects in'view which will appear as the'description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawings the preferred forms of the invention have been shown. In said drawings: r I Figure l is an elevation of a portion of a container provided with a pouring spout such as constitutes the present invention.

Figure 2-is a section on 1ine'22, Figure 1.' 1 Figure 3 is a section on line 33,iFigure 2. Figure 4 is a section on line 4--4',; Figure 2. Figure5 is a section on line 5-5, Figure 2. Figure 6 is a side elevation showing a portion of the feeding means coupled to the inlet of the dispensing or pouring spout. I a

I Figure 7 is an end elevation of the outlet' of said ieedirigmeans. V r e Figure 8 is a section similar to Figure 2 showing a modified structure. v

'Refering to the figures by characters of reference 1 designates a jar or other container for lubricant or the like and the neck portion there or is provided at suitable points inits outer surface with sockets 2 while at other points portions of a jump threadlmay be provided as shown The present improvements are all contained within a pouring or dispensing member which, in

'each of which contains'a' spring *fi'constantly thrusting againsta pin 7. A jump thread 7' can be provided in the cap. Thus the cap can be lowered ontothe neck portion of the container and by then giving'it a partial rotation-the jump thread 7 can move under the jump thread 3 and when'the parts have been sufficiently tightened the pins Twill snap into sockets 2, thereby locking the parts together so that they, cannot thereafter be separated without breakage.

The cap 4-has an elongated pouring spout 8 preferably cylindrical. 1 The upper portion of this spout is constructed to'form an outlet nozzle 9 the end of which can be'substantially beveled; as shownrat 10, and normally closed by a cap 11 preferably of metal. The inner surfacer of the wall of the cap has ribs 12 adapted to bind tightly uponthe nozzle 9.50 as to hold cap 11 in NTJOFFICEAY place but at the same time permit air to 'vent between the capand nozzle.

Fitted snugly within the lower-portion of the spout 8'is'a metal casing 13 the lower end of which has an annular flange 14 adaptedto bear downwardly on a gasket 15 supported by the end ofthe container and constituting a seal.- The upper end portion of the casing 13 is constructed as at 16 and is provided with an openin'g17.- A semispherical or dome-like baffle 18 is supported over and around the opening 17 by radial" arms-19 formed onf or joined to the'bafiie 18 and thereduced portion 16.- l r Below'opening 17 there'is provided-asubstan tially'conical baffle 20 the apex portion of which is cut away to provide asmall axial opening 21.- Themarg-in of this baffle is spaced from the easing '13 but is joined thereto by fingers122'. Below bafile 20 there is provided a supporting ring 23-joined-to the inner surface of casing 13'. Hingedly connected to this ring at diametrically opposed points and as shown at 24 are flap valves 25 which; when in their'normal or closed positions, rest upon a supporting strip 26 extending diametrically across the ring 23., The valves are a '7 too closed by a flap valve 29suspended by a'hook 3'0 7 from the- 'casing' l3. The valve is adapted-to swing inwardly toward-the axial-center of the spout and' can be limitedin its movementby a stop finger 31. f'Ihe valve can also be held againstdisplacement by laterally extended pins 32 working freely in loops 33 extendin gfjfro'm the end portions or the valve;

Extending from the wall of the spout 8 and integral therewith is an arm 34 having an intake recess 35 extending thereinto from its outer end.

This recess has an outlet 36 opening downwardly into cap 4 back of the opening 28 and valve 29. If desired one or more screens 37 can be extended across this space for use as filters. The top of the recess can be suitably shaped. For example it can be bowed downwardly as shown at 38 in Figure 1. The bottom of the arm 34 can be provided with a specially shaped slot 39 opening therethrough into the recess. A retaining shoulder 40 is located preferably on top of the arm and as shown this shoulder is under-cut.

Assuming that the container 1 is empty and that the cap 11 is in position on the pouring nozzle, a special filling means must beused to direct fluid into the container. This filling means can include a coupling sleeve 41 adapted to be slipped onto the arm 34 where it will fit snugly. It is essential that the sleeve be shaped to conform with the external contour of the arm and it is also essential that the sleeve be provided with a filling block 42 for entering and closing the slot .39. A hook 43 is carried by the sleeve and is so located that when the sleeve has been seated snugly on arm 34 the hook can drop into engagement with shoulder 40 and thus hold the parts assembled. r

Sleeve 4]., is suitably joined to a supply container hav ng forcing, means, neither of which has been shown. After the parts have been coupled as explained the fluid, is directed under pressure from sleeve 41 into arm 34 and will flow from recess 35 through port 36 and against valve 29 to open it. The fluid will thenflow into cont ainer, 1, and gradually fill it, the displaced air being exhausted between cap 11 and nozzle 9. After the container has been filled the coupling sleeve 41 is removed and recess 35 can be closed by any suitable means if so desired although the valve 29 will automatically close from the pressure thereagainst of fluid within the container so as to prevent escape of the fluid through port 36.

When it is desired to pour the contents of the container the same is tilted to pouring position and the pressure of the fluid against the valves 25 will cause them to, open. The fluid will then or upper surfaces of valves 25 insuring the tight seating of the valves. 7

Instead of constructing the device as heretofore-described certain modifications can be made therein, as shown in Figure 8. In that figure the neckportion44 of the container is formedwith an annular rib 45 on which is clinched the skirt portion 46 of a pouring spout 4'7 having a reduced nozzle 48'. Instead of providing thesuperposed baflles shown in Figure 2, the casing 49 in spout 4'1- has an annular flange. 50 above the hinged valves 51'. On this flange is supported a substantially conical member 52 in;the,wall of. which are openings53 produced by slittingthe wall of,

the baffle asshown. The upper wall of each.slit

, is pressed outwardly to provide an outwardly and downwardly inclined deflecting lip 54 while the inner wall of each slit is pressed inwardly to form an inwardly and upwardly inclined deflecting lip 55. Obviously any liquid poured from the container must flow from within the baffle 52 between the lips 54 and 55 toward the base of the baflle before passing to the nozzle 48 and because of the arrangement of the lips it would not be possible to insert a wire for the purpose of tampering with the valves.

Thearm 56 which is extended from the spout 47 has an inlet opening 5'? in its bottom, this opening being countersunk as at 58. The feed tube 59 leading from a supply can be formed with a coupling 60 adapted to enter opening 57 and countersink 58 and has lugs 61 movable into engagement with hooks 62.

An outlet port 63 extends from the recess 64 in .arm 56 to the space 65 in cap 46 back of the hinged'valve 66 which is similar to valve 29 heretofore described.

In this modified structure as well as in the structure previously described, a special form of coupling is necessary in order to fill the container;

Obviously in both forms of the device it becomes impossible to tamper with the valves because of the arrangement of baiiles, etc. Furthermore in both forms the. cap carrying the pouring spout cannotbe removed from the container after once being appliedthereto without. breakage of the parts. 2

During the pouring of the contents air can enter the container past the valve 29 or 66 or, if desired, a suitably located valved air inlet can be located wherever desired.

. An important feature of. both forms of the invention disclosed resides in the fact that the inner casing carries all of the, valve and bafile means and can be inserted readily into the spout ,before the spout has been assembled with the container. Thereafter, when the spout is joined to the containerv said container will serve to hold the casing tightly in the spout and, by clamping the gasket interposed between the container and the casing, will insure a tight sealing connection between these, parts.
