Specification of Letters Patent. i Pateted Sept. 2i, 1920,

Application led October 19, 1918.' Serial No. 258,881.

To all 'whom t may concern Be it known that I, CHARLES HAMMER, a citizen of the United States,residn at Queens, in the-county of Queens and tate of New York, have invented certain new v and useful Improvements in`Band Catsup- Qaps, of which the following is a specifica-V tion.

This invention relates to a form of closures adapted for receptacles such as bottles, that have a flange on the neck below the top., which closures have means for locklng against such flange to secure the closure on the bottle.

The object of the present invention is to provide a closure of this character, in which a sealing gasket or washer inside of the cap will be compressed against the top of the bottle, and which closure is provided with a band that will engage the lower edge of the closure, and which is adapted to be'bent inwardly at its lower edge against the bottom wall of a flange on the bottle; and which band is provided with' a tongue or projection that does not lock but merely contacts with the band, so that on pulling outwardly on the tongue the band will loosen and be removed, to permit the release of the cap for easy removal.

In the accompanying drawing showing one embodiment of my invention, Figure 1 shows the cap sealed on a bottle. Fig. 2 shows in elevation, partly in section the cap member of theclosure. Fig. 3 shows the band member separate from the cap. Fig. 4 is a plan view of the closure. Fig. 5 shows in section the closure when first placed on the bottle, and also the sealing device. Figs. 6 and 7 are similar views with the closure partly, and completely sealed on the bottle; and F igs. 8, 9 and 10 show a j U and band are shown as substantially sepamodication.

The closure as shown comprises a cap member 8 of cylindrical form, that may be drawn in a single piece, or otherwise produced as preferred. This cap has the lower edge bent outward and upward to form a kind Vof bead, or a channel as shown at 9. The other member of the closure comprises a sealing band 10, that is shown as formed of a strip provided with a projecting tongue 12 at the intermediate portion of oneend, that will lap Athe other end portion, but has no locking engagement therewith, see Fig. 3. This band is provided with a flange 13 at the top that extends inwardly, and is adapted to engage the bead 9 on the cap 8, the band being large enough in diameter to pass down over the cap, as indicated in Fig. 5. As shown ythe flange 13 is somewhat channelshaped to engage the channel-shaped bead 9.

The cap and band are so roportioned relative to a bottle 14, provided? with a bead 15 having its lower wall substantially transverse to the' bottle to form a sealing shoulder, that when the cap -is placed on the Y bottle, and contains a gasket 16, the cap will not reach down as far as the flange 15. The band 10 will engage the cap and project down around the flange 15, as shown in Fig. 5. Upon applying pressure on top of the cap the gasket will bev compressed between the cap and the top edge of the bottle, see Fig. 6. The cap and also the band will move downwardly, whereby the band will have its lower edge portion project downwardly beyond the bead 15, as shown in Fig. 6, and the band will be brought into close engagement with the bead on the cap. While being held in this position by the chuck l7,.suitable bending means are caused to engage the projecting edge of the band to press it inwardly, as shown at 18 in Figs. 6 and 7. This will cause the band to be bent inwardly at .a right angle and engage the lower wall of the flange 15, as shown in Fig.

f 7 whereby the cap andband will be securely held in sealing position.

The tongue 12 of the band that simply laps without engagement, can be grasped by the user and pulled outwardly to unwind the rate members, they can be made to be locked together prior to placing on the bottle.

In Fig. 8 I show a band 19 having the flange 20 in the form of a closed bead bent inwardly. In Fig. 9v the cap 7 shows a flange 21 on the bottom that is bent over inwardly and forms a closed bead with the raw edge concealed. These two members are shown assembled in Fig. 10, previous to application to the bottle, which is done in the same manner as set forth, by bending in the lower edge of the band 19. Means for applying this closure to the bottle as set forth in claim 3 are' not claimed herein, but forni subject matter of an application Serial NoQ 391625 filed June 25th, 1920.

l. As an article of manufacture, a closure formed of a cup-shaped cap having an external bead or rim at the entremelower edge, and a strip bent to'form aring with a flange on the upper edge that projects inwardly and engages the cap at the bead portion, which band has an extension on one'end at the intermediate portion in the form of a tongue that laps the other end of the ring strip, such ring being arranged to have the lower edge bent inwardly -against the lower wall of a bottle flange, whereby to look the closure securely on the bottle and which band is, adapted for easy removal by outward pull on the band tongue. 2. The combination with a bottle provided with an annular flange spaced below the top, of a closure formed of a cup-shaped cap having the lower edge bent outwardly and upwardly to form an o-pen channel adjacent said flange, and a sealing band in the form of a ring having a projecting tongue on one end of the band that laps the other end of the band, the band having the upper edge bent inwardly and downwardly to form an open channel that engages the said cap channel portion to removably retain the cap on the bottle, with the lower edge of the band bentinwardly around the bottle lange at its lower wall, whereby the band is adapted foreasy removal by outward pull on its tongue, and separation of the engaging channel portions of the band and cap.

3. The method or process of ap lying a l cap. closure ,to a bottle provided wit an annular flange some distance below the top, that consists in appl ing a relatively deepl cup-shaped closure t at has its lower edge extending outwardly and upwardly to form a channel which receives a sealing band having its upper edge turned inwardly and f projecting below the flange while innaintaining the said downward pressure on the cap and band portions, to bend the band beneath tie liange and secure the closure to the bott e.
