ARTHUR W. SWANBERG, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR OF ONE-HALF TO GEORGE F. GREEN, OF MINNEAPOLIS, MINNESOTA.

NON-REFILLABLE BOTTLE SPECIFICATION forming part of Letters Patent No. r767,530, dated August 16, 1904.

l Application filed October 15, 1903. Serial No. 177,109. (No model.)

To all whom it 717/04/ concern:

Be it known that I, ARTHUR W. SWANBERG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to non-reiillable bottles, and has for its object to simplify and irnprove the construction thereof. Y

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a vertical section taken centrally through a bottle designed in accordance with my invention. Fig. 2 is a horizontal section on the line x2 002 of Fig. 1, and Fig. 3 is a hori- Zontal section through the so-called lockstopper on the line m3 w3 of Fig. l.

The numeral l indicates the body of the bottle, and the numeral 2 the neck thereof. The neck 2 is formed with internal screw-threads 3, extended throughout about the intermediate one-third of its entire length, so as to leave a smooth seat above the said thread, into which an ordinary cork (not shown) is adapted to be inserted in the usual way.

At the junction of the neck 2 with the body 1 is a valve-seat 4. From the valve-seat 4 parallel guide-ribs 5 extend upward, but terminate a considerableA distance below the threads 3. The bottle is of course usually made of glass, and the ribs 5, as well as the threads 3, will be integrally formed as part of the neck of the bottle.

A glass ball-valve 6 closely fits within the cage formed by theY ribs 5 and is adapted to close the opening through the valve-seat 4 eX- cept when the bottle is inverted.

To hold the valve 6 in working position, I provide a so-called lock-stopper of novel ing a radial slit at 9. The severed portions of the disk 7 adjacent to the slit 9 are bent one upward and the `other downward, so as to give the disk a sort of a spiral form and adapt the same to be passed with a screw-like action through the threads 3 and into the space between the said threads and the upper extremities of the ribs 5. An imperforate protectingdisk l0 is rigidly attached to the disk -7 by a connecting-stem 11. The protecting-disk l() is of such diameter that it may be passed through the neck of the bottle without engagement with the threads 3-that is, it is of less diameter than the diameter of the clearance through the threaded section. The disk 7, as already indicated, is of such diameter that it -can be passed through the threaded section only by a screw-threaded engagement therewith. The two disks 7 and 10 and the neck 11 are preferably formed integral and of glass, and to enable the stopper to be screwed into working position, as shown in Fig. l, it is also preferably formed with a long stem 12. (Shown only by dotted lines in Fig. 1.) The stem 12 at its junction with the disk 10 is so formed that it may be readily broken therefrom. By means of the stem the lock-stopper is given a spiral movement, which is necessary to force `the same through the threaded section into working position, and this having been done said stem 12 is broken 0H?. When the lockstopper has been thus placed in workingposition and the stem 12 broken ofi", it will be practically impossible to work the said lockstopper out of working position.

The lock-stopper holds the ball-valve 6 in position, so that when the bottle is not inverted or turned upside down the said valve will close the valve-seat 4 and prevent the introduction of liquid into the bottle. When, however, the bottle is inverted, the ball-valve will run against the lock-stopper and the liquid will nd ready escape first through the valveseat 4, thence through the grooves between the ribs 5, thence through the perforations 8 of the disk 7, and thence outward around the disk l0. The so-called protecting-disk 10 prevents the insertion of a tool into the perforations of the disk 7 and, as the said disk 10 is perfectly smooth, it will be impossible to get sufiicient grip upon the lock-stopper to screw the same from working position.

The device described is of small cost, may be made entirely of glass or non-corrosive materials, and is thought to be eflicient for the purposes had in view.

It will of course be understood that the construction described is capable of modification within the scope of my invention as herein set forth and claimed.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

l. The combination with a bottle having a valve-seat 4 and formed Within its neck with a plurality of ribs 5, and internal threads 3 said threads terminating outward of said ribs 5, of a ball-valve 6,coperating with said valveseat 4, and a lock-stopper made up of a perforated spiral disk 7 and connected imperforate disk l which lock-stopper is adapted to be screwed through said threads into working position, substantially as described.

2. The combination with a bottle having a valve-seat 4 and formed within its neck portion with a plurality of ribs 5 and internal threads 3, said threads terminating short `of said ribs 5 and of the outer end of said neck,- of a ball-valve 6 cooperating with said seat 4, and a lock-stopper made up of a perforate spiral disk 7 and imperforate disk l0, said disks being connected by the neck ll, and having an extended stem portion l2 adapted to be broken off after said stopper has been screwed into workingv position, substantially as described. j

In testimony whereof I aiiX my signature in presence of tWo witnesses. i
