"Consideringthe construction" ofthe invention in detail, wherein like parts are given like "reference characters, the

"container-1 as shown in Fig. 1, is provided with a head suita'bly formed at 3 for the securement thereto of the bordering element for the opening and for'mounting the spout, which 'elem'ent is generallyindicated at 4 and is known in the trade as a nozzle. Such nozzle -is "formed to receivethe spout, generally indicated at "'5.

Theopening through the nozzle maybe closed against *leakage, whether or not the spout is present, by'means 'of a screw cap 6 and the closing or instruction disc "7. 'Considering first the construction ofthe nozzle 4, it

*will'be seen it is preferably a sheet metalmember, though it may be made of othersuitable material and generally takes the-form of an inverted cup. Around the bottom 0f the side wall :8 thereof, the nozzle 4 is stormed with tupwardly and outwardly turned clinching or securing ring 9. This ring, prior to application to the container =wall, forms an upwardly opening channelon the base of which an annular gasket 10is seated. This gasket is preferably composed .jof gasketing material of a nature that--fcantbe applied .ina fluid :state-and which will set to theproper' composition and resilience for gasketing purposes. -.Itmay, however, :bea pre-formed gasket which is sme'rely seated iniplace inxthe channel.

The side "Wall 8 of-the nozzle is generally cylindrical sand is threaded throughout :the major portion of its height by working the metal into a thread formation .which :provides proper threads on both its inner and outer sides.

.Abovethe threaded' portion the side wall 8 terminates in ie smallwupwardly extendingcylindrical section 11 which is turned inwardly in a :bead form at '12 and thenis =reversely bent downwardly in a small downwardly extending portion 13.

From-the portion ?13 the stock .of the nozzle is bent :directlydnwardly in a ledge 14,whichterminates in a jinto' the channel iniiuid state and-allowing it to set into the gasketing condition for which it is intended. When 10 is an exp'lode'd view, partly zinazelevation and i -iappl'ied this way the gasketingmaterial flows throughout the channel and, while conforming itself thereto, seats itselfutherein in ;a .mannerqto retain itself on its seat,

extending rounded head 33.

or a section of a cone. As here shown, however, it terminates at its upper end in an inclined mouth lying in a plane at an angle with respect to the axis of the cylindrical body. This provides for the securement thereto of an obliquely directed cylindrical extension 18, which is seamed at 1-9 to the material 20, bordering such mouth. The extension 18, as here shown, is generally cylindrical, is screw threaded at 21, adjacent its outer end, and is headed inwardly at 22, at that end, in an annular rim around the pouring opening 23. The bead 22 provides for the effective sealing reception of a gasket 24 lying within the base 25 of a screw cap generally indicated at 26. i

From the periphery of its base 25, the screw cap 26 extends down in a generally cylindrical side wall 27, formed with screw threads to mate with the screw threads 21 at the end of the extension 18. The free end of the side wall 27 is preferably beaded or otherwise formed .over the member 28 in order to stiffen or reinforce it.

The oblique extension 18 enables the contents of the container to be poured past the chime 29 of the container. Also it enables the spout to be used as a rest, during the pouring of the contents of the container. This form of spout body, with oblique extension, is generally referred to as being of the offset type.

At its end, remote from the extension 18, the spout body 17 is integrally formed into a special base which performs a variety of functions. First there may be a short outwardly offset portion 30, of a slightly greater diameter than that of the body 17. The portion 30, or

the side wall of the body 17 in the event there is no offset portion 30, terminates in a downwardly extending rounded annular bead 31, from whence the stock is inclined upwardly and outwardly at 32 into an upwardly From the bead 33 the base terminates in a straight downturned sleeve portion 34, having a straight end face 35.

Referring to Figs. 10, 11 and '12, it will be seen that the body portion 17 of the spout slides freely in the nozzle opening bordered by the lip 15. Thus when the spout is to be assembled with the nozzle in inverted position for shipping purposes, it is merely necessary to apply the screw cap 26 to the end of the portion 18, insert that end in the opening bordered by the lip 15 and let the spout drop down. When an enlarged portion 30 is used and it reaches the lip 15, it will fit within the opening therethrough but may do so relatively snugly so that it will need a light push to seat the spout down all the way. When this is done the bead 33 will seat down on to the gasket '16 to form a leakproof joint therewith.

The securing of the spout in inverted position and the completion of the closure is effected by the application of the instruction and sealing disc 7, followed by the application of the screw cap 6. The disc is circular in outline, has a raised center circular portion 36 bordered by a downwardly concaved annular channel 37. Outwardly of the channel 37 the disc extends into an upwardly formed portion 38, continuing outwardly from the channel 37 and lying in a plane below that of the top 36. The portion 38 terminates in a short downturned cylindrical collar portion 39.

Reverting now to Fig. 11, it is seen that when the spout is seated in fully retracted position and the disc 7 is in place, the center portion 36 of the disc will overlie the opening through the spout body 17, the portion 38 will overlie the end face 35 of the sleeve portion 34 of the spout and will engage therewith, while the collar 39 will extend down between the sleeve portion 34 of the spout and the downturned portion 13 of the nozzle in a light press fit with that portion 13. The end face of the collar 39 seats down on, or into, the gasket 16.

Effective seating and retaining of the spout and disc,

I in the assembled position just indicated, is effected by the application of the screw cap-6 thereover- This screw cap, or ring, has a generally cylindrical threaded side wall 40 which mates with the threaded formation of the nozzle wall 8. The side wall 40 is headed or otherwise formed around, at its lower end 41, to stilfen it. At its opposite end the wall 40 is inturned in the form of a ledge 42 which may have an intermediate corrugation to stiffen it.

The inner end of this ledge terminates in a downturned collar 43 bordering an opening through the screw cap dimensioned to receive the raised center portion 36 of the instruction disc. Thus, as seen in Fig. 1:1, on the application of the screw cap 6 and tightening the same down over a nozzle to which a spout and disc have already been applied, the screw cap received the portion 36 up in the opening therethrough and the downturned collar 43, being properly dimensioned therefor, seats in the channel 37 of the disc. The screwing down of the screw cap pushes the disc 7 downwardly, thus pushing the beaded rim 33 of the spout on to the gasket 16 as well as forcing the collar 39 of the disc down along the .side wall 13 of the nozzle and into engagement with the gasket 16 carried by the nozzle.

Preferably the collar 43 and the border of the raised portion 36 are dimensioned to form a friction fit so that the disc will be removed as the screw cap is removed. It can then be pushed out of the screw cap by simple hand pressure.

The engagement of the collar 39 with the gasket is an additional safeguard which is not needed so long as the screw cap 26 has been properly applied to the extension 1 8 of the spout. Proper application of that cap with its gasket 24 will prevent any leakage up through the spout while the gasketing at 16 precludes leakage between the spout and the nozzle. Should either of the cap 26 or the spout 5 fail to form a tight joint with their respective seats, assurance against leakage is provided by the engagement of the portion 39 with the gasket 16. The seating of the spout in pouring position first calls for it being removed from the opening and reversed into the Fig. 12 position. Here, again, it will be seen that the end face 35 on the sleeve 34 at the base of the spout, seats downon to the gasket 16 so that leakage I between the spout and the nozzle is precluded. The

spout is eflfectively held in this position by the application of the screw cap 6 after the disc 7 has been removed therefrom.

Here the collar 43 performs other important functions. Not only does the end face of the collar 43 seat in the channel formed by the downturned bead 31, around the flange base, but the opening through the collar is dimensioned to snugly receive the outer surface of the offset portion 30 of the spout when that offset is present. Thus when the screw cap is seated over the spout in its extended position and the cap is screwed home, it not only holds the spout in leakproof engagement with the gasket 16, but it also holds it rigid and in upright position through the engagement of the portions 30 and 43. Hence the spout can be used as a rest while pouring, without disturbing the tight seal at the gasket 16. For pouring purposes, of course, the small screw cap 26 is removed. 'In the absence of the offset at 30 the collar 43 holds the spout rigid principally by having its end face forced against the incline between the bead 31 and the reverse bend at the beginning of the sleeve 34.

An alternate form of sealing and instruction disc is shown at Figs. 13 and 14. Here the disc has a'raised circular center portion 45, which is turned down at 46 into a flat annular shelf 47. Outward of the shelf 47 the disc turns upwardly again into an upwardly rounded annular beaded portion 48. The channel on the under side of the portion 48 is filled with gasketing material 49, preferably flowed into place therein. The disc terminates in the marginal edge 50 forming the outer border of the gasket channel.

This disc seats in place on the nozzle and .over the spout in asomewhat different manner from the disc 7 of the form of "l :to ll. The structure of the nozzle is .just thesame as in those figures, butthe provision of the outwardly extending channel formed by the beaded portion 48enables the gasket 49 toseat down -on .the rounded head 12 formedat'theupper end of the nozzle. Thus if any'liquid shouldleak by the:gasket '16, orpast the cap 26, ,and up "through'thespout '5, it-would be'preventedfrom. escaping any further by the seal made *by the additional gasket 49 on the bead 12.

The disc as here shown is held down tightly over .thenozzl'e by'the screw cap'6 and is also properly aligned axiallywith respect toitheJ-axis of the nozzle. This results from the downturned collar 43 .of the screw cap 'niaking a close fit with the downturned surface 46 between thetop 45 and .the'ledge 47 of the disc.

An alternative form of spout for use with the nozzles, screw caps, ete, is generally illustrated at 50'inFig. 16. In'this instance the spout is shown as straight rather than offset and fformedof a plastic of sufiicient resilience to The selffgasketing. Polyethylene :is an illustrative though notalimiting exampleof such aplastic, The spout body is shown as a right section of a cone having a side wall 51 of substantial thickness though the thickness here shown is somewhat exaggerated forthe purposes of illustration. The wall thickness would be such as would be needed for the forming of an effective spout out of the particular plastic selected. .On .its lower, larger end the spout body is formed with .anoutwardly extending collar -commencing in a reduced section 52 and terminating in .an enlargedsection providing upwardly and downwardly extending annular beads 53 and 5.4.

The size and shape .of .the spout body 50 is such and the sections 52 .and 53 .and 5.4 are so .dimensioned that the spout can be ,efiectiyelyseated in either the extended .position,.as s'howninFig. .12, .or in the inverted position of Figs. 11 and 15. If in extended position the bead 54 will seat on the gasket 16. The end face of the collar 43 of the screw cap will seat down on the upper surface of the section 52 and the inner face of the collar 43 will engage the outer surface of the spout to retain its rigidity.

In inverted position the bead 53 of the spout will engage the gasket 16 and will be held down on that seat by the ledge portion 38 of the disc 7, or the portion 47 of the disc 45, as the case may be. In fact the gasket 16 can, if desired, be eliminated in this instance, so long as the material has the self-gasketing characteristics of polyethylene.

The outer end of the spout body 51 has integrally formed threads 55 extending outwardly therefrom for engagement with mated recesses in the side Wall 56 of the integral screw cap 57. This screw cap, if made of self-gasketing material like the spout, will gasket against the end of the spout and will make a liquid-tight joint therewith.

From the foregoing description of the structure and operation of the spout assembly of the invention, it is apparent that the objects claimed therefor are fully achieved and that the spout introduces improvements in the art, going well beyond anything heretofore contemplated.
