Joseph Alsfaffer Bottle Stopper

U.S. Patent Number: 324,449                   Patented: August 18, 1885

Joseph Alsfasser’s patent application was filed March 5, 1885 and specified:

I, Joseph Alsfasser…ChicagoIllinois, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification…

The object of the invention is to improve the construction of the bail to which internal stoppers are secured, thereby rendering their holding powers greater…the invention consists of the novel construction and arrangement of such bail and its combination with the stopper and bottle…

Figure 1 is a vertical section of the neck of a bottle provided with my improvement, and showing the bottle open; Fig. 2, a similar view with the bottle closed, and Fig. 3 a detail of the bail and stopper.  Like letters refer to like parts in each view.

A represents the neck of a bottle, and, as is usual, is slightly contracted at a point between its upper or outer end and its lower end, of which the bottle proper is a continuation.  The stopper consists of a piece, B, provided with two flanges separated by a suitable groove, into which a rubber disk, C, is inserted and held.  The part B is secured by soldering or otherwise to the bail D, now to be referred to.

Bail D is formed of spring-wire, and is of the form shown in the drawings.  The wire of which the bail is formed is, as shown, bent until its two free ends pass each other, thus forming a complete loop.  The sides of this loop are bent inwardly to conform to the shape of the contracted portion of the neck A, while the upper and lower portions are bent outwardly – the former to give a hold for a hook used in operating the stopper…and the latter to receive the stopper.  It will thus be seen that the stopper is secured to the bail intermediate of its free ends, and that both of such free ends are adapted to press against the neck of the bottle.

It will also be understood that the bail may be formed of two separate pieces, a a’, as marked in Fig. 3…the part a’, whether the bail is of one piece or two, is bent to form a shoulder at b’, to correspond with a similar shoulder formed in the bail.

The manner of using the device is as follows:

The user receives the bottle filled and closed, with the stopper in the position shown in Fig. 2, it being held in that position by the expansion of the spring-bail after it passes the contracted portion of the neck.  To open the bottle, pressure is applied to the top of the bail, generally by striking it against the counter or other convenient place.  This force drives the parts to the position shown in Fig. 1, wherein, as shown, the top of the bail is below the upper end of the neck, the stopper carried from its seat, and the parts held in position by the contraption in the neck being encircled and clasped by the bail.  After the bottle has been refilled by the bottler, the stopper is carried back to its seat by inserting a hook under the top of the bail and drawing it upwardly.

What I claim is…The combination, with a bottle and a spring-bail formed with two free ends, situated upon the same side of the loop formed by the bail, of a stopper secured to such bail intermediate of the ends.


Although Joseph Alsfaffer's patent application doesn’t include specific references to Charles G. Hutchinson’s bottle stopper patents, the similarities are obvious.  There is no evidence he achieved any marketing success with his closure.
