An important object of the invention is the? provision of a nozzle which is madefup of different'sheet metal parts, one of'which -is/of.

relatively soft or light weight metal adapted to be ruptured or severed for dispensing purposes.v v

Another `important object ofthe invention"v is the provision of a strong and durable pouring or dispensing nozzle, vwhich is easily severable vor' tearable along a directed severance. Y l n Another important object of the invention comprises the-provision of a nozzlel of twoA diiierent sheet metal parts pressed tightlyinto liquid-prooi1 sealing engagement, one

, within a recess of the otherto provide a non- 'i thel nozzle;

projecting, smooth, outer nozzle surface.

Another important object ofthe invention comprises theprovision of a nozzle made upf of sheet metal parts of different' strengths .pressed together in liquid-tight metal-td metal sealingV contact to eliminate an addi-4 tional 'sealing or binding medium, such as solderbetween the parts.

v Still another important object of i the Vinvention is in the inethodof 'producing theI nozzle in an enicien't, simple',"and economical manner@ Numerous other objectsand-advantagesof the' invention will be apparent asjit'is better understood from theA following description,

which, taken *in connection with thegaccompanying drawing, discloses "a preferred embodiment thereo y Inthe drawing :4

n In the' present invention, the nozzle com;y prises a neck part with an inwardly extending ruptured or-severed but is pressed infliquid! tight sealing engagement with the neck piece to form a permanent'closure and may be in' severance forthe removal ofthe contents of the receptacle by a customer..

VReferring more particularly to the drawing, a sheetv'met'al container 11 has a bottom 12 and a top 13 seamed or securedthereto. nozzle 14 is soldered orvsecured to an upstanding flange 15 of the top 13.

l The nozzle is produced Vfrom a neck part y16 0f sheet -metal ofordinary strength and *a cap part V17 ot relatively soft metal, such as t'aggers tin which `is easily ruptured yor severed. Theneck part is formed with an inwardly extending ila-nge 18, and in order to complete the nozzle the cap partl is pressed into-a liquid-tight metal-to-metal sealing en# gagemen-t with' the Vneckpiece, as shown in completed form in Fig. 5 1

Y AIn order to form as'ealing engagement-be-Y tweentheneck'and cap pieces 16 and 17, a pair of upper ,and lowerdie members 19 and 20 are provided, the upper'member being slid'- able in an annular ,die member 21 and having at its lower-face'anannular marking ridge or beadxf22. These die members'19 and 21Y are held in yielding engagement Ywith vrespect to i nozzle sriA The die ring 25 is provided with recesses 26 in its lower edge, to receive the upper ends of pins 27 having stop heads 28, and the shanks of the pins have a slidable engagement in holes 29 in a flange or extension 30 at the lower end of the die member 20. Springs 31 surround the pins 27 between the upper face of the flange 30 and the lower end of the die member 25 and hold the latter in an up-A as shown in Fig.

wardly extending position, 3, but permit this die member 25 to be yieldingly compressed downwardly when the the blanks, as shown in Fig.- 4. f

In order to properly seat the neck member 16 upon the upper end of the core die member 20, the top edge of the die member is formed with an annular recess 32 to seat the flange 18 and to form a space for receiving an inwardly pressed ridgel or bead 33 on theunder side ofthe blank 17 (Fig. 5) formed by the marking bead 22 of the upper die member 19. Also around the upper edge of the die member 2O is a recess 34 to permit the side wall of the neck member 16 to be struck inwardly and laterally recessed a distance equal to the thickness of the downwardly turned edge 35 of the cap vmember 17, this vdownwardly turned flange being of a height corresponding to the height of the recess 34 and presenting a smooth out-er surface level with the outer surface of the neck body wall whenthe die forming operation is completed, as shown in Fig. 4. p

The ring die member 25 `is also preferably formed with an inner annular recess 36 for seating a cap blank 17 therein, as shown in Fig. 3, flush with the top of the die member 2O and resting upon the upper edge of the flange 18 `of the neck member 16 before the die forming operation, as shown more clearly in Fig. 3. The die member 21 isrformed at its lower edge with an annular shoulder 37 corresponding to the recess 36 sothat it becomes seated therein as shown in Fig. 4, and the inner' edge 38 of the shouldered portion'is rounded away so that in the operation ofthe die members the depending flange 35 of the cap member 17 is formed downwardly over the neck member 16 bythe engagement of this rounded edge 38 therewith.

With this construction it will be seen that when the upper and lower dies are brought together, as shown in Fig. 4, the flange of the soft metal cap member 17 is wiped over the upperedge of the nozzle neck member 16 by the co-operating action ofthe die members 21 and 25, thereby slightly necking-in the top part of the neck, and is further pressed tightly against the top by the beading ridge 22, thereby indenting this portion of the cap member 17 and forming` a definite line of severance so that a cutting tool may be directedalong this line to facilitate the cutting out of the central part of the soft metal cap upper die member descends and operates upon for the removal of the contents of the receptacle by the consumer. The cap member 17 is struck into the recess formed at the top of the neck member 16, so that a liquid-tight metal-to-metal Contact is thus produced etween the rigid metal of the neck piece and the softer metal of the cap piece, and a flush or smooth outer surface is formed between them.

If desired, the under and inner side of the soft metal cap A17 may be coated with any suitable lining material, or only that area of the soft metal cap which comes in contact with therigid metalof the neck part may be so coated.

In order to protect the soft metal cap during transportation and until the contents of the can is to be used, an auxiliary screw capYV 39 is applied to the nozzle, the neck portion of the nozzle being correspondingly screwthreaded for this purpose in a well-known manner. Y i

It is thought that this invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that many changes may be' made in. the form, construction and arrangement ofthe parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore.described being merely a preferred embodiment thereof.

Y I claim:

1. A nozzle comprising two sheet metal parts, one of relatively softer and more easily tearable material than the other, the softer material being pressed tightly over the other material to make a liquid-tight' metal-to-metal joint with a smooth and liush outer surface, and marked to indicate a preferred line of severance for forming a pouring opening.

2. A nozzle comprising a sheet metal neck piece with an outer flanged' opening, and a cap of soft. easily severable metal applied over the opening and fitting tightly in a recess at the outer end of the neck piece so that the surface Vjoint between the two pieces is flush and Vsmooth and the' cap piece being formed with a definite marking inside of the flange ofthe neck piece to indicate a'prel ferred line of severance thereof.

f 3. In a sheet metal nozzle, a neck piece of relatively strong and rigid material, and a cover fitting over the end of the neck piece of relatively soft, easily tearable sheet metal, the cap being pressed over the end of the neck piece to make a liquid-tight engagement therewith,and the neck piece being annularly recessed and necked-in to receive the edge of the cap member applied thereto and forming a smooth flush outer surface therewith.

4. A nozzle for cans, having a top provided with a dispensing aperture, and a separate seal of soft metal covering said top and aperture and extending down on the side of the nozzle7 the lower edge of said seal and a corresponding part of the nozzle being indented inward in liquid-tight contact with each other.

5. An article of manufacture consisting of a cylindrical sheet metal nozzle having a soft metal cover formed with a depending marginal part, the nozzle having a lateral recess and an inturned flange at its upper end, the

10 depending marginal part of the cover fitting in said recess substantially flush with the lower part of the nozzle.
