Aug. 31, 1954 L. C. MILLER DISPENSING SPOUT EQUIPPED CONTAINER Filed July 19; 1949 V 6 IN VEN TOR.

in condition for discharge of the Patented Aug. 31, 1954 a 1 2,687,831 I DISPENSING SPOUT EQ IrrEn CONTAINER Lloyd 0. Miller, Chicago, Ill., assignor 'to Formold 1 1 Plastics, Inc., 1 Chicago, 111., "a corporation of Application Jul ie, 1949, Serial N6. 165,528

The present invention relates to or concerns certain novel and innovatoryphysical features and functional characteristics in the discharge spouts of pouring containers. 1 1 1 1 a A thinrigid member which constitutes part of the container of the goods to be dispensed has an inwardly tapered, downwardly projecting,tubular section into which a portion of a plastic spout is introduced and fastened firmly in position so that the spout is adequately and properly held in place under all circumstances, such passage into the container being employed before accommodating such part of the spout for filling the container with its dispensible material, for example a liquid substance.

In order that those acquainted with this art may readily understand the current invention and its various advantages, a present preferred embodiment of the same has been shown in the several figures of the accompanying drawing forming a part of this specification, and in the plurality of illustrations of which like parts have been supplied with corresponding numerals,

2 Claims. (Cl. 222-569) securely fastened thereto after or' before the receptacle 2| has been initially filled with its contents.

Thisrigidtop metal member 22 whichconstitutes part of the liquid housing container 2| hasintegraltherewith a suitably located, in-

wardly tapering, downwardly projecting section or wall 24 (Figs. 2; 3and 4) open both at itsltop and bottom through which the contents of the can may be introduced thereinto and also in which openingthe base portion of the plastic hollow spout 25 of the form and shape clearly depicted in Figure 2 with an initially closed upper end 26 integral with the material of thespout is fastened, and an intermediate, outstanding, circular flange portion 21 and a depending annular part 28 equipped atjits marginal inner end with an outstanding rim 29.

To accomplish the assembly of the plastic spout with the metal top 22 of the can a ring-die, not shown, is used to press down the spout portion 21 on the largeflat part 22 of the main body of the In the plurality of illustrations of this drawing:

Figure ,1 is a perspective picture. of the complete liquid holding receptacle, such as an oil can or other spout dispensing container;

Figure 2 is a partialflongitudinal s'ectionon line 2'-2 of Figure 1 throughthe filled tin: can receptacle and its plastic discharge spout ready for shipment or delivery to the user but not yet contents of the can; 1

Figure 3 is a partial similar section through a portion of the spout and a part of the metal endwall of the can or liquid holder illustrating the manner of mounting the spout on the can;

Figure 4 shows the three parts of thestructure in separated relation before union thereof together;

Figure 5 constitutes a top plan view of the assembled elements of the spout-equipped liquidfilled sheet-metal container before its spout has been used for discharge purposes; and

Figure 6 presents a side view of the spout supplied with a removable end cap closing its top and after such end has been manually cut oif to render it useable as the discharge element.

As will be readily understood from the drawing the main body of the flexible sheet-metal container or can 2| for the oil or other material, not necessarily liquid, to be dispensed has a rigid sheet-metal top-wall 22 with a marginal flange 23 overlapping the top end of the metal wall 2| and. soldered or otherwise appropriately fixedly and spout above its annular portion 28, the diameter of such die being less than the diameter of the hole through the member 22 so that the plastic portion of the spout acted upon is forced through the hole and will snap back and thereby beheld j tightly in place, [as shownin Figure 2, the application ofthe spout to the container top being indicated in Figure 3 although the ring-die employed is not illustrated in such figure. The spout preferably, but not necessarily, being made of polyethylene plastic or vinyl resins so that when the punch is pressed down on the plastic to drive it into the opening of the container it actually 'elongates the plastic so that the lower end of the plastic passes appreciably beyond the lower edge of the rigid member 24 through which it is being forced and the flange on the lower end of the plastic then opens out automatically beyond the diameter of the hole through which it was pressed, and when the pressure of the punch is released the plastic pulls back thus keeping a constant tension against the lower edge of the rigid member 24 assuring proper maintenance of the spout in its final expanded strained condition.

This plastic portion 25 is such that it can be bent, wherefore the exposed externally elongated portion of the spout can be bent back into normal position which it will retain, as shown in Figure 2, and remain therein.

Inasmuch as passage through the spout is initially closed at its top end at 26 by an integral part of the plastic material there is no leakage of the contents of the container until the disgrasp the end of the spout sufficiently so that it will not be accidentally displaced.

It should be fully understoodtha't inasmuch as the rigid member 22 whichs'formsmart of thereontainer has the inwardly tapered,=.downwardly projecting round section 24 of uniform depth integral therewith and into which the plastic spout is fastened, to accomplish this assembly a ring-die is employed which presses down on the :plastic material, the diameter of such ring-die being less than ithe diameter of the hole in theorigid mem- ,ber.22 so that the plastic is deformed-land forced through the space which it traverses, it necessarily tends :to .snap vback and thereby holds tightly together the spout construction .50 that when the ,punching -.die or :body ,is pressed =down lonithe plastic to .driveIitinto the opening .of the .container .it .actually elongates the plastic mate- ,rial whereby the lower .end of .the plastic mem- Lberpasses appreciabl -y beyond the lower iedgeiof .thelrigid .member .24 and the flange .on the lower .end of the plastic then opens upbeyond the-di- ..ame'ter off the .hole, and when the pressure of lthepunchiis released jthe;plastic pulls-back thus keeping a constant itens'ion against the rigid .imemberby the spout material.

It will, thereforeyfbe appreciated that the .passage into the container formed by -the round "tapered .wallZA aecomplishesa double or duplex lunction. ."First,.,theiliquid mayibe poured through theiopieningintio the .can before theispout passage has been opened and then vit securely holds the spoutboth before and after itinitiates its pouring function.
