SEALING-CAP FOR BOTTLES.

To all whom it may concern: Be it known that we, EVERETT DoUGnAs BETTS, a subject of the King of Great Britaln, and EDWARD VANDENBERG, a citizen of the United States, and both residents of I iancaster, in the county of Erie and State of New York, have invented a new and Im roved Sealing-Ca for Bottles, of which the ollowing is a ful clear, and-exact description.

In putting up sealed packages for1 the trade, of soft drinks such as beer, ale, mineral waters and carbonatedliquids, the bottles containing such liquids are sealed at the bottling works by machinery, and when the closures of such receptacles are removed, no means for sealing the bottles again to preserve air tight any of the contents that may remain in the bottles, are provided, conseuently the beverage becomes stale and dat and therefore unfit for liquid refreshment.

The object of our invention is to provide ay novel, simple sealing capfor bottles, that may be readily applied to the openneck of Va bottle, and hermetically seal the breached receptacle for the preservation of any contents of the bottle that may remain after the bottle has been first opened and a p ortion of the liq'uid therein removed.

The invention consists in the novel construction and combination of parts, as is the appended claims.

Reference is to be .had to the accompanying drawings forming a part of this speciiiy cation, in whichsimilar characters of reference indicate corresponding parts in all the vlews.

Figure 1 is a side view of a bottle neck, and of the improved sealing cap ,mounted thereon; Fig. 2 is a transverse sectional view of the improved sealing cap applied as a closure upon a bottle neck, and ig. 3 is a perspective view of the improved sealing cap, detached,

and exposing its novel construction.

The improved sealing cap is preferably made of non-corrodible metal, such as aluminum, and may with'advantage be cast .into form.

The device consists of an imperforate disk 5 rounded on the' periphery, and having a eripheral flange 5a that projects below the at lnner surface thereof sufficiently to form a'shallow recess, wherein'is embedded a flat circularly edged lanchet 6 of rubber, or other slightly yiel ing material. Integrally Spcification of Letters Patent.

lclaim* as new and desire to Patented May 5, 1908.

with the flange 5, two flanged' extensions 5b are formed oppositely thereon, each having a slo ed free edge which extends from the peripheral flange 5a to an ol'set shoulder a, said shoulders being of an equal height and disposed o positely. Upon the sloped edges of the anged extensions 5b, an inwardly turned hook flange 5C is formed on each, as appears in Figs. 2 and 3.

The improvement is designed to be mounted upon a class of bottles used for the packing of malt and aerated beverages. Usuallyl these bottles have similar necks 7, that, at their pouring ends, each terminate in a radial bead 7 a, shown in Figs. 1 vand 2.

The hook flanges 5c are spaced apart at the shoulders a on the flanged extensions 5b, a distance that ermits them to be slid into engagement with) the bead- 7 a at opposite points thereon. This is effected by `first imposing the joint planchet 6 upon the free edge of the bottle neck 7 opposite the shoulders a, and then pressing the cap piece 5 in direction of this arrow in Fi 1, which will forcibly impin e the hook' anges 5c upon the lower side of t e'radial bead 7a.

It will be seen that the sliding engagement of the cap piece, as hereinbefore' described, will compress the elastic joint planchet 6 upon the true top edge of the bottle neck 7 and-thus seal the same hermetically, holdin the Ifgaseous and liquid contents therein unti the ottle is breached by a removal of the cap piece. y It is claimed that by employment of the improved sealing cap, a great saving of the liquid ycontents of beer, ale, or soda water 'bottles may be eected, as upon removal of the corks first holding the bottle necks sealed,

and a removal of a por-tion of the contents of the bottles, the remaining gas and liquor may bepreserved for subsequent use by quickly lacing the improved sealing cap upon the bottle neck.

Having thus described our invention,'we secure by Ii'etters Patent; Y f

1. A sealing cap for a bottle neck, comprising a' circular disk, a peripheral flange thereon, two qqpposite depending flangesy on the peripheral ange and having sloped edges that are turned inward forming hook members thereon, and a pliable joint'piece on the disk held-in place by the peripheral flange.

2. A sealing. cap for a bottle neck, comlprising a fiat circularly'edged disk, an inte-v Y:lo

gral peripheral flange on one side ofthe disk, tWo op osite fianged extensions on the pe` riphera flange, said flanged extensions havmg sloped lower edges that are turnedinwardly producing hook members thereon, one end of each depending flange merging into' the peripheral flange and the other end thereof 'terminating in an offset shoulder,and a pliable joint piece seated on the disk and contacting with the peripheral flange.

3. The combination with a bottle neck,

having an annular bead at its pourin end, of

a sealing cap comprising a flat cireu ar disk, an' integral depending peripheral flange on said dis depending flanged extensions oppositelywdis osed. on the eripheral `flange, each flange aving a slope edge, said ed es inclining toward the same point on the expending, flange and having/inwardly bent members thereon, that form hooks that may 20 f EVERETT 'DoUGLAs BETTS.
