UNITED STATES SAMUEL C. MILLER, OF LOUISVILLE, KENTUCKY.

CLOSURE FOR BOTTLES.

Application filed .Tune 7, 1923.

To @ZZ whom t may conce/rfa:

Be it known that I, SAMUEL C. MILLER, a citizen of the United States, residing at Louisville, in the coimty of JeHerson and State of Kentucky, have invented certain new and useful Improvements in Closures for Bottles; and I do hereby declare the following to be a full, exact, and clear description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in closures for bottles and has for an object to provide a sealing cap which may be held tightly against rotation.

In spinning these caps which are made of metal foil or light metal, it is impossible to secure a tight fit of the cap upon the stopper. The cap is therefore free to turn and its lack of tightness and ability to rotate combine to loosen the puller which is associated with the cap.

It is jthe `purpose of the invenltion fto compensate for this deficiency in the spinning operation and to place the cap under frictional tension at all times w'hich effectively avoids its rotation and at the same time tightly seals the pull7 in place and prevents the pull from slipping around the bottle neck.

`With the foregoing and other objects in view the invention will be more fully described hereinafter and pointed out in the appended claims.

In the drawings in which like symbols refer to like parts throughout the several views,

Fig. l is a fragmentary side elevation of a bottle neck with a portion of the cap shown in section and with the cap in an initial position Fig. 2 is a similar view showing the cap in its final position;

Fig. 3 is a vertical section through a bottle neck and associated parts; and i Fig. i shows a plan view of the cap and compression disk.

Referring more particularly to the drawings, 5 designates the neck of a bottle having a bead 6 formed outwardly of its mouth and a depression or annular groove 7 just inwardly of the bead. At 8 is shown the cork or bottom portion of the stopper which fits within the neck of the bottle and at 9 is represented the head of the stopper which is connected with the cork body and Serial No. 644,026.

is provided with a roughened or corrugated outer surface for convenience in turning. The head 9 is wider than the cork body to permit such head to rest upon the neck of the bottle or upon the upper edge of the bead G.

The metal cap is shown at l0 and is of substantially cup shape being adapted to lit about the top, edge and sides of the stopper head 9 and having its marginal edge arranged to be driven into the groove 7 by a spinning operation. The cap is in this manner secured over the stopper. Now, it is impossible to spin the edge of the cap in the groove 7 so tightly as to avoid the rotation of the cap upon the bottle neck and this rotation encourages looseness in the seal and also in the pull.

According to the present invention a disk ll of a material adapted to take a relatively high compression is fitted within the cap l0. The disk l1 normally expands to the condition such as shown in Figs. l and lin which the expansion takes place axially. The diameter of the expanded disk ll should accurately conform to the inner diameterI of the cap so that no space will be left to be filled by the expanding disk when the cap is put under compression. Just prior to spinning the edge of the cap into the groove 7, the cap and the disk beneath it are compressed downwardly under relatively heavy pressure and the spinning operation is performed while this pressure is still upon the cap. The disk l1 is in contact throughout with the upper surface of the stopper head 9 and consequently such disk will be compressed axially at all points through its surface and it will not be permitted to expand radially due to the tight fit it has in the cap lO. The mass will therefore be compressed locally at all points and this compression will at all times act in an endeavor to expand in an axial direction and to lift the cap upwardly, but the cap will be restrained by the engagement of the spun edge with the bead (i. A tight frictional effect will therefore be transmitted to the cap throughout the entire upper area thereof engaging the upper edge of the disk and also throughout the contacting walls of the bead G and the inwardly compressed edge of the cap. This has been found to prevent the rotation and any consequent looseness in the cap.

The pull7 is represented at l2 and it is ing the disk 1l the soft material of which,

the disk is made will permit the ribbon to embed itself diametrically inthe disk and this will serve to prevent the ribbon from turning about the neck of the bottle and it W'ifll also afford a much better hold for the ribbon when the pull is being operated.

rl^he disk `1l is preferably of lightl cork, although other material may be found suitable for the purpose.

lt is understood that changes in form, proportion, size'7 and minor details may be made Within the scope; of the claims without departing from' the spirit or sacrificing any of the Y advantages of the present invention. l

Wha'tfis claimed is v a 1. In. combination' Withk a bottle neck having an' annular groove externally thereof, a stopper' having a' portionv extending into the bottleneck and asecond outer portion of greater diameter than the inner portion seatedupon the' upper end ofthe bottle neck, a resilient' gasket seated upon theI upper surface of the outer portion of the: stopper,

said gasket having greater resiliency than the said outer portion' of the stopper, the outer porti'oir of said stopper being. substantially' fiat andlr continuous toY support thro'ii'ghoutthe resilient gasket, said' gasket' being of: substantially disc` form and of substantiailly' the saune diameter as the outer portion ofthe stopper, a cap' fittedsnugly.

about .the upper and edge portion of said gasket and about the edge portion of the outer part of the stopper, said cap also overlapping the bottle neck and having an edge portionv spun into the groove, said gasket being put under compression before the edge is spun into the groove whereby the spun edge may hold the gasket compressed, and a pulling' stripy fitted between said gasket and the cap and embedded by the cap into" the material of the conipressible gasket When pressure' isk put upon the cap whereby the stri-'p is prevented from pull:- ing longitudinally' or turning in the cap.

2; In combination With a bottle neck havingk an annular groove externally thereof, a stopper having a portion extending into the bottle neck and!` avsecond outer portion of greater diameter than the inner portion seated uponl thei upper end of the bottle neck,I a resilient gasket seated upon the` upper surface of the outer portion of ther stop-` per and havin-g greater resiilaency than thel said outer portion of the stopper', said gasket being of substantially dise form: and

of substantially the same' diameter as they outer portion of the stopper, and a cap fitted snugly about the upper edge portion of said gasket andabout the edge portion of the outer part of said stopper', said cap also overlapping the' bottle neck and having an edge portion spun into the groove, said resilient gasket being put under compression before the edge isv spun into they groove, whereby the spunl edge may hold the' gasket compressed.
