Terrill whomit may co nea/m vorlina citizen of the United Statesof Amer ica, and residentofO'sWego, county ofOs- -wego, State of New York,have invented certain new, and useful Improvements in and Relating to, Clos ure Caps for Containers, ofwhl'ch the following is a specification.

An object of the invention isto. stiffen and strengthen.the arcuate panels of the cap flange, that are bounded'at the bottom by the flange ;rim and'at the top .by the rouglr ened rimof the cap and that intervene between the flange portions in which the locking on "wedging lugs areglocated, with the ends in. view of maintaining the flange 1n v circular or approximate cylindrical form,
and. ofreducing to the minimum possibility ot' buckling or distortion of the cap flange. or straighteningout or stretching of suchv panels,-' under the stress and strain of the wedging action of the lugs'on the complementaryxportionsof the container neckor moutlior while the cap is sub ected .to the twisting or rotary action of the hand during the operations of locking and releas ng the.
cap, and to facilitatethe production of such caps by the use of thread rolling machinery.
With this and other objects in view, the invention consists in certain novel features in construction and formation, as more fully B" it [known that I, Crimsror'Hnn JEivS hereinafter.
Referring to the accompanying .drawings,u

and particularly described and specified forming apart hereof: Fig.1v showsln side elevatiolnonv an enlarged scale, a capembodying my invention and the'mouth or neck portion of con-= itainer sealed thereby.
This invention relates to exterior closure ,caps',ffor jars and other containers, of :the type composed of thin, more .or less flexible,
2 is a detail elevation of the con tamer mouth or neck portion.
Fig. 3 is a horizontal section throughthe container mouth. andthecap thereon.
FlgJl isa detail vertical section on the l1ne 4;&, Fig. 1.
The cap shown is composed otthin metal onother suitable material to provide the closed top Wall 1, and an annular depending p skirt or flange having the preferably'rolled or beaded bottom annular edge or rim 2, and
the roughened or corrugated annular base port-ion3, forming the flngerhold or grasp-' ing rim of thecap by which the cap is grasped to apply the rotary or twisting force necessary to lock the same on and release ,the same tromthe mouth or neck portion 4 of any suitable container, such as 5 This annular ,series of; closely arranged vertical is usually approximately cylindrical.
rim" portion 3, is usually formed by an The annular portion of the flange that is bounded at the topby the rim portion 3, and
at the bottom bythe beaded edge 2, is in-' Wardly indented or depressed atspaced intervals, to fornrthe usually-inclined longitudinally-elongated inwardly projecting locking or wedging lugs'fi. In the part1cu lar example illustrated, Ishow :tourlocking lugs 6, uniformly; spaced apart around the flange. although I do not wish to so limit ny invention; These lugs are designed. to co-': Y
operate in the usual manner with any suit-,
able exterior container mouth or neck formation whereby the cap can be placed longitudinallyon the container nrouth and then partially rotated to'cause the lugs Gto catch and wedge-under shoulders or spaced ribs of the container mouth to draw the; cap down'tig'htlyon and sealing the container iouth"; and whereby on rotary or twisting movement in the opposite direction, the cap will be released for lifting from the container.
The arcuate panels 8, of the flange that intervene between the flange panels that are indented or pressed in to form lugs 6, have heretofore tended to stretch or straighten outunder the stress of the cap locking action, and have resulted in cap flange buckling and distortion and objectionablebinding of said panels'on the outer surface of the container neck and interference'with the desired free and easy application and release of the cap.
I have overcome this tendency by indenting, ribbing or corrugating the panels 8,
each by means of a multiplicity of indenta tions 9 at the outer side of the flange forming rounded or bevelled" ribs projecting radially inwardly at the inner side ofthe flange; said indentations 9, can be relative ly'shallow and narrow with respect to the depth and width of the lugs 6, and ifso de-' sired elongated "circumferentially of the flange, forming longitudinally elongated ribs or corrugations. Each rib 9 can be of anysuitable length with respect to its panel 8, and, if so desired, can be divided into 1011- gitudinally alined spaced sections extending approximately throughout the length of its panel 8, as shown more particularly by Fig.
1. "Also, each panel 8 is preferably provided with several spaced parallel lines or rows of indentations, say approximately as shown by Figs. 1 and 3. Preferably each panel 8, from end to end and from rim to beaded edge, is approximately covered by a multiplicity of spaced indentations.
By providing the panels 8 with the stiflening indents, I can form caps of very thin sheet material that possess the necessary stiffness and strength against distortlon to meet the requirements of use and of the trade.
- The mouth, or rim 4, of'the container in the example shown, is exteriorly cylindrical except for four uniformly spaced circumferentially elongated longitudinally inclined ribs 7. The cap of my invention'is formed to exteriorly and longitudinally slip onto the mouth of the container with the locking lugs moving down in the spaces between the ribs 7 and clearing the ribs, and with the panels slipping down over the ribs 7. Then on clockwise rotation of the cover, the top edges of the locking ribs of the cap flange vwill slide under and wedge against the under edges of the ribs.
It is obviously necessary and desirable to produce caps with properly spaced locking lugs, to approximately register with the spaces on the container rims intended for the longitudinal passage of the cap locking lugs, and to enable all of the locking lugs of the cap to act simultaneously in wedging produce the locking lugs spaced with the de- 7 sired uniformity in the flanged caps of this type-wherethe panties between the locking lug areas are indented in accordance with my. invention. I slipping of'the chucks of the'threadrolling machinery on the cap flange and require'the chucks to uniformly feed the capflange and hence result in uniform spacing of the look; ing lugs. The indented areas also preserve the desired round or cylindrical shapeofthe cap flange during the operationf of the thread rolling machine. The threa'drolling machine operation is comparatively inexpensive, and the same is true of the chucks thereof. E
It is obvious that various modifications and variations might be resorted to and hence I do not WlSh to limit my mvention to the exact disclosures hereof.
What I claim is 1. A container cap, of thin more or less These "indented areas prevent ed edge, and at its annular portion between 7 said grasping surface and said beaded edge formed with panels having uniformlyspaced inwardly-projecting locking lugs and intervening panels between the panels of said lugs, each intervening panel having an indented area approximately throughout the length thereof and separate from said edge and said grasping surface, to stiffen said panel against longitudinal stretching and flattening. 4
2. A cap for containers, composed of thin flexible material, having an unbroken permanent cylindrical depending flange with a stiffened annular lower edge, said flange above said edge having an annular series of uniformly-spaced in-pressed locking .lugs
and several'spaced longitudinal rows of indentations intervening between saidlocking lugs and formed therein by a thread rolling machine to maintain the proper spacing of said lugs and to stiffen the flange against distortion from cylindrical form by longitudinal stretching and flattening of the portions thereof between said lugs.
3. A container cap of thin material having an unbroken permanent depending annular flange formed with a circumferential series of inpressed separate uniformlyspaced looking lugs and a circumferential series of intervening panels between the locking lugs and each Within its boundaries and approximately throughout its length having an area of several rows of closely arranged indentations for stifiening said panels against longitudinal stretching and flattening from the original curvature of the flange. i
In testimony whereof I have hereunto set my hand at Fulton, N. Y., thislth day of July, 1925.
