8 Claims. (01. 222-527) This invention relates to an extensible and contractible flexible pouring spout structure normally inestable in'a "container and mounted in *annpening therein and whichspout is of sealmg or scalable type. I

Thech'iefzobject of the present invention is to provide a spout ofthe aforesaid type andmountablewithin a container, or a' portion thereof, by

hand or machine as desired and at the time of container manufacture or subsequently, as for example, after a container is filled and the lid isto-be applied thereto. I i

The chief feature .of the present invention resides in peripherally anchoring :in an opening in a. container or a part thereof or in immediate proximity to that opening a flexible collapsed spout structure wihichiis normally nested wholly within the :container and is extensible therefrom for pouring purposes.

Another feature .ofthe present invention is that such spout is of sea-led, semi-self sealing or scalable type.

A further feature of the present invention is that one embodiment is capable of faucet replacement on a barrel for the dispensing of antitreeze liquid or the like.

Other objects and features of the invention will be set forth more fully hereinafter.

The full nature of the invention 'will be understood from the accompanying drawings and the following descriptionand claims: I

In the drawings Fig. 1 is a top plan view of a portion of a conventional cover or lid for a conta'iner and with ioneformof the invention applied thereto. i i i i Fig. 2 is a central sectional view of the same form applied to :a somewhat similar lid or cover, dotted lines indicating the extended position of the spout, the inventionherein being shown associated with a cap seal.

Fig. 3 is a central sectional view through a portion of a "modified .form of the invention prior to mounting and having a cap sealingclosure applied to the pouring end.

Fig. 9 is a top plan view of a slitableclosed' end of a pouring spout embodying the invention. dotted lines indicating where the slit maybe made. l In Figs. 6 and "7 the anchorable end of thespout is intentionally omitted for it :may be of the type shown in Figs. '2, 4, 5 or 8, as desired or required. I

In Figs. 3, 4, 5 and 8 the central sections'are not extended since Fig. '2shows the opposite side to be adup1icate in reverse of that illustrated.

Fig. l0 is a 'centralsectional view of a moditied and the preferred form of the invention. parts being shown in' the collapsed and shipping or storage position.

Fig. 11 is a similar view oi. the sameform with l the parts in extended position, certain parts *being removed to permit subsequent dispensing; dotted lines indicating the non-dispensing pos'ition. i

In Fig. 1 of thedrawings Ill indicates the de tachable lid or cover of'a containerhaving a pouring spout H applied to opening l2 therein, said lid having a peripheral groove formation13 with radial, apertured tongues 14.

'lnFig. 2, [5 indicates a detachable lid or cover defined by a reversely grooved peripheral port- 1 tion lfihavingradial, apertured tongues ll. The

opening T8 in the lid is definedby outwardly and laterally directed portion l9. Seated in said opening is the anchoring flange 2!! of the outer portion 2| of the pouring spout. An internally grooved head 22 rests upon the outer edge of portion I 9. Aclamping ring 2'3 secures the same together in leak-proof relation. This ring is of light metal and is readily deformed by a hand operable crimping tool or a crimping tool supported and operated by a power operable press,

Fig; ;5 is a similar view of a steel barrel application of the invention, the barrel fixtures beingnf the American Flange type.

Fig. 6 is; at central sectionalview of. a portion of a faucet replacing-embodiment ofthe .invention, the parts being shown in the collapsed position. I i i Fig. 7 is a similar view of the same embodiment in the extended position, dotted lines indicating the cut-off condition.

depending upon whether the spout is applied in the field or at the factory at the time of container formation, respectively.

Herein the outer portion 2 is of tapered cup like form and disposed wholly within the same is the oppositely tapered inner portion 24, the two being connected at the closest adjacent ends by integral shoulder-like formation or portion '25. Thesmaller endof the innerportion is closed by integral portion 26.

Whenever desired or required a cap seal 21,

having gripping vflange 2.8 engaging and looking .to anchor .ring 23 maybe applied. This prevents accidental extension of the spoutsh'ould the .container be disposed upside down in "transit or storage. Of course, when the container contents are to be used the cap seal aforesaid, which has been applied by a crimping tool, must be removed.

The inner ="portion of the spout isdisposed as shown in spaced relation to the larger and anchored outer portion, the spout when nested I A cap seal similar to that shown at 21-28 may forming an outwardly opening channel 29. The

thumb and fingers are inserted therein and the smaller end gripped therebetween and pulled out wardly about the connecting intermediate shoulder portion or formation 25. In this operation, the latter portion is inverted. The-parts, when the spout is extended, assume the position as shown by dotted lines in Fig. 2.

For pouring purposes the end 26 may be slit or be applied to the socket 39 and now standard barrel construction.

In Fig. 5 there is illustrated the invention applied to'the conventional steel'barrel or drum equipped with conventional fixturesof another type. Herein 43 indicates the barrel metal, 44

ime socket thereof, 45 the flange (of drop in type),

46 the gasket, 41 the bung or plug, and 4B the reversed anchoring portion on the flange for socket mounting and gripping purposes.

l Herein the tubular spout includes the outer fbeaded end 49 and the metal clamping ring 50 anchors the spout to the portion 48 as illustrated.

the end may be cut out. or cut off as desired.

When pouring is completed, portion 24 is again gripped and forced inwardly,'the portion 2| also being similarly forced inwardly accompaniedby reversal.

Certain synthetic rubber materialsare petroleum product resistant. Also certainplastic mater-i als are resilient and flexible. Thus the invention may be comprised of any suitable material compatible with the purposes hereof and duly resistant to the contents of the container.

" Dotted lines herein indicate the ring portion prior to crimping upon portion 43. As before the 'spoutis like that shown in'Fig. 2 but can be of the type shown in Figs. 3, 6 and '7, or Fig. 8 as desired or required. I W

Wherf bar'rels are loaded with alcohol'or anti-w freeze'solutions itis customary to remove the; plug orbung 42 or 41 in Figs. 4 or 5 respectively;

- and screw into the flange a faucet. F'Ihebarrel The presentinvention obviously provides a seal for "a container which inthe form so far disclosed is of tamper indicating type. It also provides a plug or closure. It furthermoreprovides an extensible and collapsible pouring spout.

In Fig. 3 there is illustrated a second embodi-. ment of the invention andsame, as the firstform includes the outer portion 30, the flanged outer end 3!, the inner portion 32,'the connecting integral portion 33 and the clamping and anchoring light metal ring 34.

Herein the two portions '30 and 32, are oppo-,

sitely tapered and the smaller end of portion 32 isexternally beaded as at 35. Secured thereon is a suitable cap type seal of light metal ora thus equippedis mounted so the faucet. is;disposed-.at 'ornear the lowest end so the contents can be drawn off intermittently by. the service:

station attendant. 1, One form of the present invention readily'lends I itself to faucet use with this advantagethat there is no projecting faucet to constitute'a-potential: accident hazard. This form of the invention'is shown in Figs. '6 and 7 and since it is equally ap plicable tothe barrels shown in Figs. 4 and 5, the

material the same as that of which the spout is made. :36 indicates the closure portion and 31 indicates the anchoring rim or flange.

In'this embodiment removal of the cap type seal immediately exposes the open end of the spout. This cap type seal may be of finger applied type or crimping tool applied type. In the latter event it and bead 35 may be severed from portion32. In the former the seal can be applied and removed at will as often as desired.

Extension and collapse of this spout is effected as previously described.

I Reference will now be had toFig. 4 wherein there is illustrated an example of a steel barrel or drum provided with conventional fixtures anchoring portions of the combination spout and.- faucet structure is intentionally omitted. 0b; viouslythis embodiment may be mounted on lidsor covers as well, as shown in Fig. 2, but its great-* est application is as previously stated;

' In Figs. G and-7; 5! indicates an outer tapering portion connected by intermediate integral p'or-a tion 52 to inner oppositely tapering portion 53.

The smaller end 'ofsthe latter pr'eferablyis closed as at 54 but same'may be omitted or this end may be formed as shown at 35 in Fig.3 and closed by a light metal seal. I I 1 The modification shown in Figs. 6. andv 7, however,-is intended'to show the application .of a cutoff device herein shown in the form of a tube 55 externally applied to'the inner-portion 53 intermediate its ends and suitably anchored or secured thereto, see bead 55. r This tube is slotted asat 51. Intel-posed in the slot is the pivotal portion 58 of a clamp member having finger piece 59 with curled free end 60 and arm 6| with curved clamping end 52. It-will be remembered' that the spout provides an ex;

modified as required herein and as'hereinafter pointed out. I I

,; In Fig. 4, 38 indicates the barrel portion having socket 39 formed therein to clampingly engage and seat the internally threaded flange '40.

Gasket 4| and bung or plug 42-completie the standard structure.

Herein flange 40 includes onits inner .end an outwardly directed lip 40 To this lip is anchored by a crimping tool the outer end of the outer portion of the spout structure by clamp ring 40 Dotted lines indicate the ring prior to tool deformation into anchoring portion. 'For purposes of illustration the spout structure is illustrated as that shownin Fig. 2 but it may partake ofthe'form shown in Figs. 3, 6 and '7, or Fig. 8

. that opposite sides of inner portion 53 have in terior contact, the same being crescentv like in a's'found most expedient or desirable, the. purpose of illustrating Fig, 4 being solely to show steel barrel application for alcohol, gasoline or 01 1.1 6-

' cut-off position as shown in Fig. 61

section. When the member 58--62 is so disposed the curled back edge of portion 63 does not cut the surface of the spout. Also finger piece 60 does notcut the spout. It may be of such size that the same contacts the outer wall defining channel 63 so that outer portion -5 news the rneinbe'rin the aromas 5. When the barrel or drum'iis properly posi tioned and the screw plug-aforesaid removed, the end 54' may be diametrically slit as indicated in Fig. 9, or cutoff or a piece out out or-i'f terminated as shown in Fig. 3, cap 36 t is removed. Then with member '54 still in out-off position the spout is extended, as illustrated in Fig. 7, and as pre-.

viously described, for dispensing purposes.

This is then effected by moving the cut-off member from the position shown in Fig. 6 'to the position shown in Fig. "7, reference being had to the full lines only and the relative position of that member to the slotted tube. If desired the cut-off member may be permanently and positively pivoted to slotted sleeve 55.

When dispensing the requiredminor amount is attained, the cut-off member isreturned to cutoff position. When the drum is positioned so that the spout, when extended, projects in a pathway, the spout can be renested or collapsed into the container, which event the cut-off member is constrained to and held by the outer portion inthe said cut-ofi position. .Thus the nested faucet type spout is not a potential accident hazard.

Reference will now be had to Figs. 8 and 9. Herein a further modified form of the basic embodiment of the collapsible and extensible spout is illustrated. This form, however, does not require inversion of a portion thereof for .extension. Otherwise expressed. this form is not of telescopic type, that is,-one part of the spout lcloes not telescope appreciably into another part thereof.

In Fig. .8, M indicates a. cover or lid or aportion of a drum or keg having opening defining portion M with reversed flange 55. The spout herein includes closed end 65 at the .outer end of bellows portion 6?! connected at .58 to the inner end of the outermost portion -69, shaving portion 'lrflsecured to flange Baby clamp ring 1 l.

The .full lines in Fig. 8 illustrate the container nestable spout in the collapsed position. Itma he suitably retained therein by cap seal I: havingflange 13 crimped to the portion e4 as shown. Qbviously the .ke etc... chime, not shown, preferably projects beyond the outer plane of portion 64 so that the cap l2-l3 does not project beyond the outermost plane of the adjacent chime.

When the canals removed, the .constraintis removed, and the spoutautomatically extends to the dotted line positionin Fig. 8. 56 may then be slit along dotted line 74, seoEig, .9. The outer end of the bellows portion 61 obviously may be cap sealed :as shown in Fig. 3,.i1f desired. When the slitend is utilized, this constitutes a semi-sealed end. Compression of the junction between portions .5 and 169 will effect opening end portion 65 atsl-it 'Mior rapid-discharge. Release of such compression will promptly result in the end closing because escape pressure on end 66 will tend to effect sealingbetween the adjacent walls formed by the slit 14. l

Reference will now be had to Figs. ,llland 11 wherein the preferred form of the invention is illustrated. Therein indicates the container shellor Llid having opening defined by-fiange T1. The flexible spout. includes the inner irustoeonica'lportion l8 united at 1.9 to the outer frustoconical portion an having the anchoring bead formation Bil. The .slopes.are of opposite charactor. A clamping ring 82 has its inner and router flanges 83 and 84 disposed in clamping association to grip therebetween flange 11 and bead 6 8!. The inner flange has inner extension :85. while the junction between head 81 .andportion 80 provides shoulder '80. Disposed therebetween is :a parafilned paper board cap .86.

This waxedpaper cap bears upon a light metal dust cap having central portion 81, side wall 88 and outer flange 89. The .dust cap "is nested in the outlet end ofthe inner conical member 18. This dust cap has iits flange .39 hearing 1011 the :discharge end 9d of :member 713. .A sealing memlerane .iil is disposed across member it between the ends. As herein illustrated the dust cap "bears on this membrane. Thus the collapsible spout can be held in nested relation under slight or greater pressure by the parafilned cap.

When dispensing is desired, if no exterior seal be employed, the paper cap is cut out, the dust cap removed and then the membrane out outor lit a shownin Fig. .9. The spout is then extended for pouring purposes,see Fig. 11 full lines. When further dispensing is not immediately desired, the dust cap is reapplied. To prevent accidental discharge the spout is then collapsed, see dotted lines inF'ig. 11.

While theinvention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.
