The band it has its upper margin The closure 9 forming the subject matter of spun inwardly over the edge of the cap to form the present invention comprises a shell having a retaining rim H or flange and extends clowna circular top portion Ill and a depending marwardly to enclose and engage an annular rib i8 ginal attaching flange H or skirt formed thereformed on the bottle neck, the diameter of the rib so on. A sealing liner l2 disposed within the top and cap being substantially equal. The rib E8 of the shell may be formed of a disk of cork or forms a downwardly facing shoulder 89 under other suitable material which preferably is covwhich the lower margin of the band is turned, ered with a thin sheet of acid resisting metal thereby completely enclosing the cap and rib and foil l3, as a protection for the contents oi the holding the cap against any movement that will 55 Lil tend to loosen it while being transported. The band I6 is scored at 20 to provide a conventional tear strip 2| for removing the band.

Fig. 2 illustrates a type of container having a relatively long neck portion such as, for instance, a wine bottle, wherein the band I6 is of increased Width to present a more pleasing appearance than would the narrower band shown in Fig. l, and further to more nearly simulate the appearance of the foil or cellulose caps now generally in use on such containers. Fig. 4 shows the 010- sure 9 applied to a similar type of container from which the sealing band has been removed. Thus an effective reseal is provided.

Figs. 3 and 5 illustrate a type of sealing band 22 which is entirely removable from the container on destroying the seal and is formed from a strip of relatively thin sheet metal. A tab 23 or finger piece is provided on one end 24 of the strip and is connected thereto by a relatively narrow neck 25. The reduced width of the neck 25 adjacent the tab 23 forms a shoulder 26 on the tab, the purpose of which will become apparent presently. The opposite end 21 of the band 22 is provided with a transverse slot 28 having longitudinally tapered end walls 29. The greatest width of the slot 28 is sufiicient to permit the passage of the tab 23 therethrough, the end walls 29 tapering to substantially the width of the neck 25. The side wall 30 of the slot adjacent the end 2? of the strip is provided with score lines 3i or weakened portions to permit tearing when it is desired to destroy the seal to open the container. The ends of the band are connected previously to applying it toa bottle by passing the tab 23 through the wide portion of the slot 28 until the band can be expanded and the shoulder 26 and neck 25 drawn into engagement with the narrow end of the slot until the shoulders 26 overlie the tapered end walls 29, thereby preventing withdrawal of the tab 23. The diameter of the band when expanded is substantially equal to that of the cap, thus necessitating destruction of the wall 39 to remove the band.

The upper margin 32 of the band is turned radially inward over the margin of the cap in the manner shown in Figs. 1 and 2, previous to its application to the cap, and the lower margin 33 is then spun under the bead l8, thereby preventing unauthorized and undetectable removal of the band.

Removal of the band is accomplished by grasping the tab 23 and pulling radially outward and in the direction of the scored wall 30, whereby the member will tear along one or both of the lines 3| and preclude any further use of the band. The band may then be expanded and removed from the bottle, leaving the cap in sealing engagement with the bottle neck.

Application of the present closure to bottles of the above character and particularly those formerly employing corks or stoppers of extra length eliminates substantially all the confusion and effort now required to open them. The adhering quality of the cork ring M to the surface of the glass, when the closure is applied, prevents accldental removal of the closure, which at the same time is not suflicient to prevent easy manual removal thereof. It will be observed that the entire closure presents a greater exposed gripping and sealing surface than is present in any ordinary type of stopper.

Modifications may be resorted to within the spirit and scope of the appended claim.

I claim:

The combination with a bottle having a reduced neck formed with an external bead encircling the same, the outer peripheral surface of said neck above said bead being free of external indentations or projections and tapering upwardly and inwardly, of a slip-on closure telescoped over said neck above said bead and comprising a circular disk-like top, an annular flange depending from the margin of said top, a resilient sealing disk disposed within said closure. said disk engaging the top and having a diameter substantially equal to the diameter of the same, a metal foil liner underlying said disk and concealing the same, a resilient sealing ring disposed within said closure in snug engagement with the inner surface of said flange and, together with the sealing disk, gripping the marginal portions of the foil liner, and a circular ring-like band having its upper edge beaded over the peripheral margin of said top and exposing the central region thereof and having its lower edge beaded underneath said annular bead to maintain said closure in telescoped position on said bottle neck.
