BOTTLE-SEAL.

Specification of` Letters Patent.

Patented Aug. 27,1907.

Application lled June 4,1907. Serial No. 377,17L

To all teh-om it 'may concern:

Be it` known that I, EDWARD D. SCHMITT, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bottle-Seals,

of which the vfollowing is a specification,

This invention relates .to improvements in bottle seals. f

In my application liled October 3ro, 1906, Serial Number 337,249, allowcd'November 19th, 1906, I show a cap whose flange is perfectly straight and whose of the bead on thev bottle neck. In this construction, on account oi the flaring action that takes place in applfying the seal, there is a tendency to split the lower edge of the cap, which tendency in some caps, is `sufilcient to split the lower portion of the flange at intervals,

producing an undesirable ragged edge.

The main object of this invention is the same as that of my former application above referred to, that is to say, to produce a cap in combination with the wellknown bottle, in which the sealing member or compressible cork disk is prevented from being'cut in the application of the seal. p

In the construction about to be described, the essential features of my former invention are preserved, while I go a step further and form the lower part ol the llange `of a diameter slightly greater than the upper part, ormore nearly the diameter at its lower edge, oi4

the beadAoi the bottle, to which the cap is applied. The flange of the seal'abd ve the lower edge is consider` ably smaller in diameter than the bead so that the sealing member is brought to a knife edge, at or slightly beyond the center of the upper edge of the bottle, with the metal of the cap in close contact with the bead, adjacent to the locking member. I lind, too, that by making the lower edge of the yflange wider than the upper part, the cork disks or sealing members are more readily introduced` in the cap and centered therein within the narrower portion of the flange.

In the drawings illustrating the invention: Figure l is a sectional View of theupper portion oi the bottle, with a seal in juxtaposition thereto; Fig. 2 is a sectional view of theupper portion of a bottle and a seal or cap with the parts in about the position they assume just before the lower edge 4,of the flange is crimped, pinched or indented into locking engagement with the locking,

shoulder or under surface of the bead on the bottle; Fig. 3 is asimilar view showing the seal locked; Fig. ll is a side elevation of the upper portion of a bottle and seal, showing'the latter applied.

Referring to the drawings, the numerall designates a bottle of the kind new in very common use for beer and other beverages, and upon which seals known as crown seals are applied. This bottle has an annular laterally extending bead 2, adjacent to its mouth, the

under surface of which serves as a locking shoulder or u surface.

The numeral 3 designates the cap which I form wit-li,

an upper flat portion 4, rounded top 5, and fiange 6,

which liange in the present instance, is of smallery bottle, so that when thesealing pressure is` applied,

after the lower part of the flange has been forced'over the bead, the upper narrower part will engage the bead and be flared outwardly until the sealing disk 9 engages' the upper edge ofthe bottle, where it is compressed into a reduced edge, extending to a point slightly beyond the center of the upper edge oi the bottle, at which point further pressure istransferred from the sealing member to the bead of the bottle, where an auxiliary seal is formed at about point a. The lower portion of the flange is then crimped, pinched or indented into locking engagement With the under surface of the bead, producing o. lirmlock-and effecting a perfeet seal, which, aside from beinggproof against internal pressures, or against the escape of the contained liquid,

is proof against the admission oi outside air to the scaling member, or the entry of insects or foreign substadrces, which may be injurious to the sealing member.

The widening of the flange at its lower edge serves' to more readily start or center the cap in applying it to the bottle, as well as overcoming any tendency to split the lower part of the Iiange in forcing the cap upon the bottle.

Claims.l Y

l. In u bottle seal, the combination with a bottle, havlngau annular external bender locking shoulder adjacent to its moutlua sealingl member of compressible'material,

:1 hard metal cap or securing member having u. flange, thel upper part of whlchlis of normally smaller internal diameter' than the head or locking shoulder upon the bottle, said cap or seeurlngiuember adapted, when. it is applied to the bottle, to confine the sealing member upon the edge ol the bottle and to directly engage the bead with sulrl upper portieri, und thereby remove further sealing pressure from the compresslble sealing member yto prevent cutting thereof, the Ilange of the cap being adapted to be forced into locking engagement with the locking surface of the bend or locking shoulder upon the bottle.

2.
