BAND-LUG CLOSUERE.

, Application illed'January 19, 1922.

To all whom it may concern:

cli.

Be it known .that I, CHARLES HAMMER, a citizen of the United States, and a resident of Queens, in the. county or Queens and State of New York, have invented certain new and useful Improvements in Band-Lug Closures, of which the following is a speciication.

This invention relates to closures for glass containers, the object thereof being to provide an improved combined removable sealing band and a rotatable and reusable closure.

One of the objects of the invention is the provision of a shallow flanged capv having a strengthened rolled or beaded edge provided with inwardly extending locking projections formed from such beaded edge and adapted to engage the projections or threads of` a glass container, and Va removable sealing band cooperating with the cap in such way 4as to materially extend below the flange thereof and engage directly with a shoulder of the container whereby the cap is secured on the container and the package effectively sealed, yet when the sealing band is removed the cap is reusable on the rotation thereof to seal the container during the further use of the contents thereof.

Another object of the invention is the provision of an improved combined removablel sealing band and a rotatable and reusable closure having a strengthened .rolled or beaded edge provided with inwardly extending locking projections, in which the band and the flange of the cap are of substantially the same depth and in which the band directly engages the rolled edge of the cap and the under wall-of a shoulder of the container for sealing the cap on to the container when the cap is first applied thereto, and in which the container is provided with a special form of multiple threads orprojections and a shoulder spaced at such distance therefrom that the cap and the band can be sealed u'nder considerable downward pressure without the cap projections engaging such shoulder.

In the accompanying drawing illustrating one embodiment of my'invention, Fig. 1 is a plan view partially broken away.

Fig. 2 is -a partial vertical section of the cap and band beforesealing. j

Fig. 4 shows the use of the cap after the sealed package has been opened.

Fig. 5 is a partial view looking inwardly on' the flange of the cap to show the lug.

This improved closure comprises a metal cap 2 and a sealing band 3 particularly applicable to a glass container. such as a jar 4. The cap 2 comprises a top having a shallow flange or skirt 5 provided with a lower strengthened edge in the form of a bead or rolled edge 6, preferably obtained by rolling the lower edge of the flange upwardly and outwardly, so as to conceal the raw edge of the flange and render it more sanitary as well as prevent injury to the hand of the user. This beaded or rolled edge is provided 4at intervals with inwardly extending locking projections 7 (see Fig. 5) of which four are shown and in the present instance these projections are formed directly from the rolled edge, preferably by' shaping or de-` formingl such rolled edge, as for instance by flattening the same to project the projections radially inward a suilicient distance to engage the projections or threads of the container.

The container or jar 4 is provided with four projections or threads-8 on its neck of special formation. that is to say, the projections or threads of the glass container comprise a single row of projections having their ends spaced apart. Each -of the projections has a relatively inclined edge terminating at an end 9 in a relatively sharp inclined portion. The container is also provided witha rib or shoulder 10 spaced below the lowermost portion of each thread 8, sullicient to permit the lugs 7 that engage the lower faces of the container threads, to pass along without being. brought into engage' ment with the rib 10, As stated, the end portions 9 of the container threads are preferably tapered and the adjacent ends of the threads are separated or spaced apart to permit the applying of the cap with the lugs passing downwardly between these ends, without the usual turning movement required where the threads overlap.

The closure is further provided with a` band 3 with its upper edge 13- bent inwardly 105 'l tongue to hold the bands together so asfto permit the loosening of the band by simply bending out these tongues. It will be fury ther observed that the rib 10 projects out wardly a greater distance than the projections 8 on the jar neck, and the band 3 is of a sizeto pass down in engagement with the outervwalll of the rib 10, see Fig. 2.

In the application of the closure to the jars/.the cap 2, preferably with a liner disk 12, is placed 'on the jar with the lugs passing downwardly between; the ends of the `threads 8, thus permitting the ycap to seat on the jar. It is not necessary at this time to bring' the lugs 7 into binding. engagement with the threads 8. Thereupon, the band 3 is passed downwardly over the cap.` and over the rib 10 of the' jar until its flange 13 engages the `bead. 6 on the. cap, as indicated in Fig. 2. This will cause the band 3 to project downwardly at its lower portion a short distance below the rib 10, see F ig. 2,and the lower portion 14 of the band is thereupon bent inwardly against the lower wall of theV rib l0, as shown in Fig. 3. Preferably considerable downward pressure is brought to bear on the top of the cap, or on the top of the flange 18ct theI band, or atboth of these places, and this pressure is Inainl tained while the band edge 14 is bent iny wardly against theI bottom of the rib 10. During this o eration, it will be understood that the lugs from the threads 8 on the jar neck, because of the free space between these threads'and the ribL 10.

When it is desired to open the container,

i the band tongues are bent4 and the band easily removed. j This will free the cap for removal, Where only part ofthe jar contents are removed, the cap can be replaced a number of times, and these lugs 7 will engage the threads 8 on the jar to furnish a Vvery tight seal by merely screwing it down, yet ermit easyV removal. While the lugs 7 as sliown are formed by iattening of the bead 6, it is to be understood that any form of lug on the iiange can be employed, in .y

combination with a beaded edge adapted to be engaged by the sealing band.I

From the foregoing it will be seen that the skirt or flange of the cap is of just sufatcent height or depth to overlapvr the threads ofethe glass container, so that the cap can be made with a shallow flange or 'skirt while the sealing band is of such .depui or height that it will have its upper inturned edge engaging or overlapping the strengthened or rolled edge of the cap and Vextend beyond the lower edgerof the cap to overlap theshoulder or rib ,of the glass container suiiiciently to permit its lower edge to be bent under such shoulder. And that furthermore, the shallow'ilange is of just suicient depth to enable its lugs to pass under the glass threads of the container can move downwardly away and eilectively pass therebetween andthe shoulder of such container, which latter projects sufficiently beyond the glass threads to enable the overlapping seaiingband to cnf gage the same on its outer wall, and. to be bent directly under such shoulder 1n an eii'ective manner to hold the cap in place.

Furthermore, by reason of the space he tween the ends of the glass threads the cap can be eiiiciently pressed down without turning it when the sealing band is applied,

and this effective sealing is also obtained "even though the Y capY maybe somewhat turned by reason of the sharp inclination at the ends of the threads, since the effective drawing down of the cap islargely obtained by the 'long gradual inclination at the underside of the glass threads.

Thus by this construction, I'am `able to provide a combined shallowflangedrotatable cap having a strengthened or `beaded edge provided with locking lugs and capable of ready reuseand'asealing band cooperat ing with such strengthened edge andthe container` shoulder itself thereby to hold the `cap on the lcontainer and seal the same. Y

And I believe that I `am therst to pro` vide a combined shallow flanged cap and sealing band in which theband and the cap are of substantiallythe same'depth and in `which the capis provided with a strength cned or rolled-edge having lockinglugs, so that it is a rotatable and reusable cap when the sealing bandy is removed. l

And I also'believe that I am the first to provide a shallow flanged cap having a strengthened or .rolled edge with locking lugs or projections extending inwardly from such strengthened edge in combination with a sealing band, wherein the structure of the cap and the glass threads is such that vertical movement Aof the cap projections in one direction during the operation of sealing the band under the shoulder is permitted. The use of .this improved cap permits the user to readily determine whetherthe cap has been tampered with at any time removal of thesealing band.

It is to be understood that by describing i or the requirements of the prior art.
