means for detachablyI engaging cop'erative portions formed uponthe `exterior surface vof the receptacle.

The particular object of the present invention is toprovide a closure of this class made up of two lseparately'florined parts,l and to provide a simple and eiicientmeans for positively locking said two parts rigidly together. And a further and more detailed object is to form the flange portion of the structure independently from that portion which is intendedl to cover1 the Open end of the receptacle, and to-provide said sepa- .rately'fornied flange portion with strucklin parts ,forretaining the lcover portion in rigid relation thereto, .andlto adapt said struck-in parts alsoto retain a sanitary lining in fixed relation-against the under surfaceof Vthe cover portion.

While this invention may be lpractised in the manufacture of closures-forreceptacles having any size Openings, it is,'however, of particular value in the4 production of closures for receptacles having Arelatively small openings, such forvinstance'as ordinary catchup'bottles and thelike. Closures forfsuch bottles comprise asmall cover part and a relatively deep, or wide, flange part. These small closures heretofore have always been 'formed by drawing the metal to form the wide flange and this operation has preeluded the possibility of ornamenting the cover. part with Ia printed design, for the reason that such ornamentation must necessarily be impressed `before the drawing operation and would of course be defaced in.

the drawing Vopera-tion. By forming the cover part independently of the iange any desired ornamentationv may be impressed without danger of defacement.

trating lthe blank used yin the formation of they flange: portion of the device; and Figs.

4' and 5 illustrate modifications. y Referring to the vdrawings for a. full description of the device, the numeral `1 indi- Cates the bottle -whichmaybe provided with a'tlireaded exterior. surface at;2. Tlieclosure illustrated comprises a disk portions 3 arranged for closing the open end of the bottle and having its marginal portion le turned downwardly to a slight extent about the annular outer edge of the `bottle; A linjing 5 may .be interposed between lthe disk:

and the upper surface `of the bottle for sanitaryv and sealing purposes, 'if' desired. It will be observed' fromthe drawing that the -lining 5 is heldin position within the tubular member through dts engagement. with the corrugated portions l0 and that said liningA covers and conceals theedge of the disk3; i

The flange `portion of the device is 'formed independently of. the disk 8 and comprises preferably a band of thin metal, see Fig.l 3, bent into tubular formation and seamed together along its abutting edges as by a seam 6. Seam' 6 is what may be termed an inter-folded seam in that the edges of the 'strip are covered and concealed bytheseam itself. The mannerof formingthe seam,

as 'will be noted, positivelylocks. the ends of the strip aga-inst relative endwise movement.

The blank from which the-bander flange is formed is preferably provided with cut- .away portions as conners as shown, so as yto provide a portion at the upper end of the. tubular.v member, .formed by the band, which .is not seamed,

7 and the upper annular edge yof the' tube is bent. to form an inwardly projectingannul lar flange 8. The lower portionof the tube is pressed to provi' gations which extend lengthwisev of vthe stripkof material constituting the tubular member, said corrugations when the ends of the band of metal are together forming con.- tinuous threadsv on the bottle, andinte'rmediate the threaded fportion and .the upper l annular edge, the

derstandingof ythe 'precise manner in which y made'from asuitable` vblank'asv Aabove described',ior otherwise if -outer, `face engages-the, inner face of the flange 8, which fin effect,.comprises an annular shoulder against which the disk may be forced. The diameter ofthe disk is just sufk cient to permit its passage between the lthen smooth walls of thetube.

At this timethe annular edge ofthe disk is also smooth. 'With the disk thus positioned, the closure issubjected to an operationwhereby the cormigations 10 are impressed, andthe ma.`

"terial of the tube as at 11 forced against the vbottom edge of the disk, causing said edge' to be wedged upwardly asis clearly seen by reference to the. drawing. This wedge action results in more or less mutilationor bending ofthe edge of the disk, which mutilation and bending will'serve to more-intimately connect the parts in rigid relation. The portions ll 'of the corrugations form a relatively -inclined or cam-like ledge or shoulder within ,the tube,and the downturned partv shoulder. and urging the cover 3 constantly upward. f

, As clearlyvshown inl Fig. 1 of thedraw does not extend straight tion 3, but. is inclined" or curved outwardly' and downwardly'on a wide radius, and 4that the' lower edge,y of the flange engages the upper 'inclined or beveled surface of the corrugations or reinforcing ribs 11, and that the bent,.o'r resilient tendency, of the lower edgeof the flange to spring outwardly is exerted' `upon said, inclined surface in'v a The downward and' outward inclination of the lflange .4 isl seen to .be such that an approximate pivot about which the flangeswings is positioned somewhat nearer vto the vcenter of the cover'part than 'the lower edge of thevtiange, so that, in

moving outwardly, said loweredge will also move upwardly. The .l 'angle of pressure against thellnclined surface is very acute.

the flange in4 engaging the in- 4 of theA cover 3 forms a spring plane of the disk porioo vIn this manner the wedge-like actionfof the g lo'wer edge .of

clined surface will produce a force which' A materially increases the normal resiliency of the metal 1n. forcing thel disk toward the parentthat in such a structure, the .disk is not ,subjected to any severe-manipulation .during-,the assembling ofthe parts, and I may therefore paintor print upon-the upper lsurface ofthe disk anylsuitable advertising Vmatter or design without fearof its de'facement.' Such advertising or other matter will obviouslyfliein a plane below theI outer surface of thelflange portion 8 of the tube, Aand will? Iconsequently vbe protected to a greateror"less.extentby said flange portion against defacementby foreign objects. 'f

vSince the'irr'egularities of,surface of the'- flange l or tubular portionof the closure areformed by simple pressure and hence the tubular portion is not subjected to the severe hardship of being drawn, this part, as well as the disk'part', may be lacquered over or painted or printed with an advertising design or the like, before being pressed-, if desired, without fearof defaceinent.

The disk portion 3 may, if desired, be

fprmed of card-board instead of metal, and

bottle without the necessity for a separate only a series of spaced ears or extensions l2 instead of the continuous formation 4 shown.

in the previous figures, or by making the part '-l narrower and making the ears 12' as enlargements thereon.k These ears will engage the surfaces l1 of the corrugations 10 and retain the parts'in rigid'relatio'n in the l'same manner as alreadyl described, and the' part will require less material in its formation, and will result in a lighter weight and less expensive structure. The ears or extensions will give more readilyto the` formation of the corrugations` ofthe tube, and thus renderthe operation Yof forming'the corrugations that much easier. They will also form independent spring members yield-` ingly pressing upon the inclined surface 4l1 ofthe Acorrugations to `wedge the cover up The structure shown in illustrates the use of a separately vformed locking member for the disk part'of the closure. VIn this instancel the disk 13 4is formed without thegturned down marginal part 4: Vand a separate ring shaped' locking member 14 of substantially L cross section is employed in its stead, one leg of the L engaging, and being subjected to the wedge action of theA kupper endsof the corrugations 10 in the same manner as is the part 4, and the other leg oftheL engaging beneath the disk 13 and forcing. the disk against the flange 8.

In this structure the disk 13 may be made of paper or cardboard, and the closure be correspondingly cheaper, without detracting rom the rigidity of 'the connection of the disk within the tubular part.

As many changes could be made in the above construction and many apparently widely different embodiments of this invenbev interpreted as illustrative and not in a' tion could vbe made without departing from the scope thereof, it is intended that all matter contained in the above description or' shown in the accompanying drawing shall limiting sense. It is also to'vbe understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all 'statements of the scope of the invention, which as a matter of language, might be said to fall therebetween. Having-thus described my invention what -I claim as new and desire to secure4 by Letters Patent, is:
