SPECIFICATION forming part of Letters Patent No. 579,564, dated March 30, 1897.

Application filed November 1'7 1896. Serial No. 612,449. (No model) To all whom, it may concern.-

Be it known that I, WILLIAM SMITH DAw- SON, accountant, a subject of the Queen of Great Britain and Empress of India, residing at Ghusury, Howrah, in the Province of Bengal and Empire of India, have invented a new and useful Improvement in Bottles, of which the following is a specification.

Bottles closed by means of corks or stoppers in the manner hitherto in practice oifer no sufficient guarantee that the contents have not been tampered with nor the bottle refilled with a liquid or substance other than that indicated by the brand or label on the same. Even when the ordinary bottles are sealed or capsuled it is possible to replace or counterfeit the marks in such a manner as to render it extremely difficult, if not impossible, to detect the fraud.

By my invention I render it impossible for the contents of the bottle to be tampered with in any way after filling until the bottle itself has been broken in such a manner that it cannot be used over again without its being clearly evident that the bottle has been opened.

I carry my invention into eifect in the following manner: The bottle, which may be of any suitable material, shape, and size, has the portion of the neck into which the cork fits ordinarily specially formed, as follows: The aperture at the lip of the bottle is similar to that of an ordinary bottle to the depth Below this orifice there is a chamber of slightly greater diameter and below this another smaller chamber of thesame diameter as the orifice of the bottle. A short piece of the upper part of the interior of the neck is separated from the rest of the neck by an annular impression, preferably in the shape of a semicircular cavity, and immediately below an annular boss or thickening in the outer wall of the neck.

The stopper which I use for my improved bottle is constructed of porcelain or other suitable impervious material provided with a band or washer of india-rubber, cork, or other elastic substance. The top of the stopper is fiat and circular. The lower end thereof is preferably in the shape of a half-round piece with the elastic material on the shank thereof, as aforesaid. When the bottle has been filled with the liquid or substance for which it is designed, the stopper is inserted and passes down through the orifice and the upper chamber and lodges in the lower chamber aforesaid, the top of the stopper being formed of the requisite diameter to pass easily through the orifice, but to be retained in position by the shoulder of the lower chamber, which forms a seat for it. In order to prevent the removal of the stopper, there is then inserted a cruciform piece of steel or other suitable substance, the prongs or bars of which are turned upward at a suitable angle and the center piece of which rests flat upon the top of the stopper, while the ends of the bars lodge in the upper angle of the recessed chamber beneath the orifice. In place of this cruciform piece other devices, such, for in stance, as a spiral spring, might be adapted for the same purpose; but I prefer the arrangement first described. This piece of metal is especially designed to hold down the stopper against pressure from within, particularly during the drying of the cement covering. Where no internal pressure exists, it may be dispensed with, if desired. The cavityis. then completely filled with a suitable cement which surrounds the steel piece and fixes it immovably in its position. Any suitable cement or filling maybe employed for this purpose, such as plaster-of-paris, silicate, rosin, or other plastic material which can be filled in and allowed to harden; but the substance which I at present prefer to use is Portland cement. The orifice being thus completely filled the bottle may be sealed or capsuled in the usual manner and the operation is complete.

Referring to the accompanying drawings, Figure 1 represents a View of my improved bottle filled, stoppered and sealed. Fig. 2 is a View of the stopper; Fig. 3, a section of the neck and mouth of the bottle; Fig. 4:, a section of the stopper; Fig. 5, a section of the neck and mouth of the sealed bottle, showing the various parts of the closing apparatus in place; Fig. 6, a modification in which an ordinary cork forms the stopper; Fig. 7, a retaining device for stopper; Fig. 8, a view of the bottle and neck after the top has been broken off and the stopper reinserted.

Like letters indicate like parts throughout.

A denotes the stopper, of porcelain, glass, wood, ebonite, or othersuitable material, and B the cylindrical washer on the shank thereof.

G indicates the bottle-mouth; D, the upper and wider chamber; O,the lower and narrower chamber.

E is the annular impression or notch in the interior of the neck.

F is the retaining device. tail in Fig. 6.)

J is the outer ridge or annular boss around the base of the top of the bottle.

K, Fig. 5, indicates the cement filling over the stopper.

A, Fig. 6, denotes the cork serving as stopper in that modification.

The bottle having been filled the stopper A is inserted and passes freely through G and D, resting in the lower part of the chamber 0, Figs. 3 and 5. The steel or other piece F, Fig. 6, when used, is neXt inserted, its center resting on about the center of the top of the stopper A, while the prongs are bent upward, so as to engage firmly beneath the upper shoulder of the chamber D, as shown in Fig. 5, and the chamber filled with cement, as aforesaid. For certain purposes I may employ an ordinary cork in place of the rigid stopper described. Such an arrangement is illustrated in Fig. 6 of the drawings. The chamber 0 is dispensed with and the cork pressed down into the neck of the bottle until its top is level with the lower angle of the chamber D. The piece F is then inserted and the chamber D filled with cement, as described. The seal II or capsule or the like may then be aflixed.

In order to open the bottle, it is struck with a hard substance in the direction indicated by the arrow, Figs. 3, 5, and 7, at the point immediately below the projection J. The neck of the bottle being much reduced in thickness at this point by the recess E easily fractures below the head of the stopper, but above the lower end thereof, so that the loose top of the bottle can be easily removed, withdrawing the stopper at the same time without permitting any dust or fragments of glass to fall into the interior of the bottle. The stopper can then, if required, be removed from the broken top of the bottle and reinserted, as shown in Fig. '7, to serve as a temporary closing device.

WVhat I claim is 1. A bottle, having immediately below its outlet-opening, a recessed chamber of greater diameter than said opening, a seating-chamber of less diameter than the recessed cham- (Shown in deber and arranged below the same providing a bearing-shoulder, a stopper having a flanged head and a shank portion said head resting on the shoulder, and a cement filling in the recessed chamber said filling resting on the flanged head of the stopper, substantially as described.

2. In combination with a bottle having an outlet-opening with a recessed chamber of larger diameter immediately below the same and a seating-chamber below the recessed chamber of smaller diameter than the same presenting a seating-shoulder, a stopper having a flanged head resting on said shoulder, a fastening device comprising the piece having the central disk portion resting on the head of the stopper and the arms extending upwardly and diverging therefrom to engage the upper shoulder of the recessed chamber and the ocment filling in which the fastening-piece is embedded, substantially as described.

3. In combination the bottle having an outlet-opening with a recessed chamber of larger diameterbelow the same, and having the seating-chamber of smaller diameter presenting a seating shoulder, the stopper having a flanged head resting on the shoulder, and the cement filling in the recessed chamber, the said bottle having a groove E immediately below the seating-shoulder and having an outer rim on the outer side of the bottle opposite the groove, substantially as described.

4. In combination with the bottle having immediately below its outlet-opening, a recessed chamber of greater diameter than the said opening, a seating-chamber of less diameter than the recessed chamber, and arranged below the same providing a bearing-shoulder, a stopper having a flanged head and a cork body fitted to said seating chamber and shoulder and a filling of cement in the recessed chamber resting on the flanged head of the stopper the said bottle having an annular depression with an outside rim so disposed that the greatest thickness of the bottleneck is along a line drawn horizontally from the inner depression, and the least thickness is along a line at an angle of forty-five degrees downward from the same.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
