This inventionrelates to the art of pack agingand particularly to a closure cap and to apackage. The principal, objectgof. the inventLon i-s to provide an inexpensive effective closure adapted to close a plurality of types of containersr Q.

parent from the following description taken in connection with the accompanying drawings. T, n f The inventionis disclosed in the form of avsheet metal closure cap having a cover portion and askirt portion. At intervals-about the skirt .thereare. provided angle shaped. inpressed portions of metal which act aslocking projections. Each of these locking .project-ionsconsists of anarm. which extends circumferentially of the skirt and a second arnr which extends substantially vertically of the skirt.

This closure is adapted to be applied e'ither to, a. container provided. with projecting screw vlugsor toa container provided. with a friction sealing Zone which may diminish in diameter from top, to bottom where itis engaged by. projections on. the cap. [When the cap is appliedto the first typeo'l cons tainer, the cilcumfierentrally extending arms of the cap lngsengage the. m1 ilerneath side otth'e container lugs. and act as screw.

threads. ,Tl evertical arms of the ,cap lugs act as deten'ts to arrest. rotation of the cap when 1t has beencompletely screwed on the container. NVhjen the. cap is applied to av container provided with a, friction .finishior the like, the lockihgprojections .of'the cap act as friction-.buttons which cooperate with the finish of the container.

Fig. 3 is a fragmentary sectional view showingthe; closure ofsFig. lapplied to a container having a so-called friction or snapbottonr of the: skirt. locking projections 4c are positioned at suitable intervals about circumferencebfthe ski rt. Asshown, these locking projections may be formed by metal plished inwardly from the skirt. Each of these projections. of angular form and comprisesa substantially horizontaliarm 5, which extends oircumferentially of the skirfl and .snbstantially vertical arm 6, which is approximatelyperpendicular, to the arm 5 at its end As shown in Fig. l, the-upper s'nrface. of the'arm inclined downwardly toiormlthe operative surface of a screw thread; and as shown in Figs. 1mm 3. the verticalarm 6: preferably so varies in depth thattherinner' surfaceaot this arm tapers outwardly radially ot the cap.

[The cap is applied to a container otthe type shown in Fig. 2 bypassing the locking projections lcdown between the container lugs Tiand then rotating the cap in a clockwise direct-ion, looking down upon the cOntainer... The upper-surfaces of the arms 5 engage the'under surfaces of the lugs 7 and lock the cap on the container. NVhen-fthe' diameter at the center 9. Beneath the center portion 9, the finish curves inwardly and forms a cap engaging zone diminishing in diameter from top to bottom of the zone.

The cap is applied to the container of Fig. 3

by pushing it directly down over the finish. As the lugs 4 approach the center portion '9 of the finish they are pushed outwardly, while intermediate the lugs the skirt flexes inwardly. As soon as lugs. 4: have passed the center of the finish theresiliency of the skirt causes it to spring into its original shape, thereby moving the lugs l inwardly with the result that thecap snaps into place upon the container. As shown in Fig. 3, the .taperingnnner surface of the vertical arm 6 conforms to the shape of the finishfof the container; and this surface, together with theoperative surfacelof the horizontal arm -5, causesthe lug to actas a so-calledfrm tion button, which holds the cap in place upon the container. I i

The present invention is adapted to either a deep flange cap, as shown in Fig. 1, or a shallow flange cap, as shown in Fig. 4; and

the cap may be formed with a plain edge, as

shownin Fig; 1-, or with a suitable wire edge, as shown in Fig. 4c. i I

It is seen that the present invention provides a simple inexpensive type of cap which, in addition to other advantageous. features,

has thecharacteristic that itis adapted for sealing either containers witha screw lug finish or containers with a friction type of finish.

Having thus described my invention, what Iclaimis: i

1. In'a closure cap; a skirt having a locking projection comprising an arm extending circumferentially of the skirt, the upper surface of said armbeing inclined to act as a section of a screw thread in the application of the closure to a suitable container; and a detent extending upwardly at one end of said arm, said detent being formed of metal pressed inwardly from the body of the skirt.

2. In aclosure cap, a skirt having a locking projection comprising a horizontal portion and an upwardly extending impressed portion, said upwardly extending portion having an inner surface which tapers outwardly radially of the cap to conform with the taper of a friction zone on a container.

3. In a closure cap, askirt having a locking projection comprising an arm extending circumferentially of the skirt and an arm extending substantially Vertically of the skirt, the upper surface of the first arm being inclined downwardly from the vertical arm to form a section of a screw thread and the inner surface of thevertical arm tapering radially outward'trom bottomto top thereof.

l. In a closure cap, a-skirt having an angularly shaped locking projection adapted to act as a screw 111g in theapplication of said zone and a tapering,verticalarmlike wise engaging said zone.

6. A package comprislng a container hav mg a cap engaging zone diminishing 1n .diameterwfrom top to bottom; in combination with a cap comprising a skirt embracing said zone, said skirt having horizontal and vertical inpressed portions engaging said zone and said vertical inpressed portion varying in depth to conform' tothe shape of said zone. i I

7. In" a closure cap, a cylindricalflsheet metal skirt comprising a plurality of lI l wardly pressed projections each" of which comprises a vertically extending arm and a circumferentially extending arm inclined. downwardly from said vertically extending arm, the end of said clrcumferentially extending arm joining the end of said vertically extending arm, resilient springy sheet' metal portions between said projections, and an annular corrugated zone above said projections. 1 i 1 8. In a closurecap; aJcylindrical sheet metal skirt comprising a plurality of wardly pressed projections, each of which comprises a vertically extendingarm and a circumferentially extending arm inclined downwardly from said vertically extending arm, the inner surface of'said vertically ex-. i

tending arm being tapered outwardly from bottom to top resilient springy sheet metal portions between said projections; and an annular corrugated zone above said projections. I j

9. In a closure cap; a long cylindrical sheet metal skirt comprising a plurality of inwardly pressed projections positioned at' a considerable distance below the top of the cap, each of said projections comprising a horizontal arm and a vertical arm joined end to end; and resilient springy sheet metal portions between said projections.

10. A package comprising a container having a finish rounded in a vertical and horizontal direction. adjacent its mouthyin combination witha closurehaving a cylindrical sheet metal skirt comprising a plural ity of inwardly pressed projections each of which has a vertically extending arm and a circumferentially extending arm; and ref silient springy sheetmetal portions between said projections, said projections being held in cooperative relationship with the finish of said container by the resiliency of said portions. I I i 11. A package comprising a container ing arm with its end joined to a circumferhaving a finish adjacent the mouth adapted entially extending arm inclined downwarcb to cooperate with projections on the skirt of 1y from the vertical arm, each of the arms in a cap; in combination with a cap having a cooperating with the finish of the container 5 skirt embracing said finish, said skirt havwhen the cap is inplace thereon.
