PHILIP RODENBERG AND MOSES R. RENDELL, OF NEW YORK, N. Y.

NON-REUSABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 689,912, dated December 31, 1901.

Application filed December 31, 1900. Serial No, 41.683. (No model.)

To a, whom it may concern:

Be it known that we, PHILIP RODENBERG and Moses R. RENDELL, citizens of the United States, residing at the borough of Manhattan, New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Non-Reusable Bottles; and we 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 appcrtains to make and use the same.

Our invention relates to bottles and means for closing or stoppering the same to prevent them from being refilled or used a second time to receive a fraudulent imitation of the genuine original contents.

The object of the invention is to produce a bottle which can be easily and readily emptied of part or all of its contents, but cannot be refilled in the ordinary manner, and if pressure be resorted to to force liquid into the bottle the neck will be perfectly and permanently closed and sealed and the reuse of the bottle rendered impossible.

In the accompanying drawings, Figure 1 represents a vertical section of a bottle with a stoppering contrivance constructed and arranged upon the principle of our invention. Fig. 2 is a sectional View of the neck of the bottle tilted or inverted, showing the position assumed by the movable parts of the stoppering device when the contents of the bottle are being emptied. Fig. 3 is a similar view of the neck of the bottle, showing the position of the movable parts of the stoppering device when pressure is applied to force liquid into the bottle; and Fig. 4 shows the position of the movable parts when the bottle is in a horizontal posit-ion. Fig. 5 represents the several parts of the plug detached from each other.

Referring to the drawings, A designates a portion of the body of a bottle, B being the neck, which is made in the usual manner in the form of a more or less perfect cylinder of any desired length. One of the superior ad vantages of our invention resides in its requiring no change in or novel additions to the interior of the neck of the bottle such as usually characterize bottles of this kind and which make it so difficult and frequently impossible to form the neck in a material so refractory as glass. The only point in which the neck of our bottle differs from an ordinary bottle is in its having a shallow annular groove 1 inside the neck a short distance from the mouth. The forming of this groove will present no difliculty to the skilled glassbottle maker, as it can be molded in the neck by means of a simple tool. This groove will be more particularly referred to hereinafter in connection with the contrivance for closing or stoppering the bottle. This contrivance consists of a cylindrical glass bushing 2 of nearly the same diameter as the inside of the neck, so that it can be inserted therein as easily and closely as possible without danger of fracturing the neck. This bushing is made in two parts 3 4:, put together with a thimblejoint and cemented. At opposite points on the sides of the bushing recesses 5 5 are formed, and in these recesses springs 6 6 are inserted and secured in any suitable manner at their lower ends, while their free upper ends project and are more or less curved outward, so that when the bushing is inserted in the neck the springs can be forced back into the recesses far enough to pass inside the neck and when they reach the annular groove 1 drop into the same, and thereby lock the bushing in the neck permanently and securely. The sides of the bushing are provided with openings 7 7, and at a point just below the upper ends of these openings a stop-plate 8 is fixed or formed as a part of the bushing. The diameter of this stop-plate is greater than the interior, but less than the exterior diameters of the bushing, so that openings 8 are left between the edges of the plate and the neck of the bottle in line with the openings 7 7 for the passage of the liquid outward to the mouth of the bottle. In the bottom part 4 0f the bushing a valve-seat 9 is formed and a central perforation 10 is made in said part. This part is also provided with downward extensions 11 11, that terminate with a ring 12. Between the ring and the sides of the neck of the bottle there is an annular space 13 for the passage of the liquid to the perforation 10 when the bottle is inverted to discharge its contents. In the periphery of the part 4, which is of the same diameter as the part 3 of the bushing, is an annular groove, in which is inserted a packing-ring 14, of rubber or other suitable material, that projects out of the groove, so that when the bushing is inserted in the neck the packingring will be compressed, and thus make a tight joint that will prevent liquid from passing between the bushing and the neck in either direction.

A valve 15, made of cork preferably, but other suitable material may be substituted, is placed in the bottom part of the bushing, resting on the valve-seat 9 and projecting downward through the perforation 10. This valve is connected by an aluininium wire link with a weight 16, which is thus suspended like a pendulum centrally below the ring 12, the weight being thus permitted to swing freely in any direction without lifting the valve from its seat; but when the bottle is inverted or tilted far enough the weight falls on the ring, and thus lifts the valve or permits the outflowing liquid to force the valve off its seat.

In the part 3 of-ihe bushing between the valve-seat and the stop-plate 8 is a plunger or piston 17, which is retained in place merely by the sides of the bushing, so that it is free to move by gravity alone between the valve and the stop-plate. WVhen it is down on the valve, as seen in Fig. 1, its sides form a close joint with the sides 18 of the lower end of the part 3 of the bushing. The under side of the plunger is concave to adapt it to fit closely over the top of the valve, and if pressure be applied to it by attempting to pump liquid into the bottle it spreads the head of the valve and makes it fit more tightly on its seat. To the periphery of the stop-plate 8 is fastened one end of a fiat spring 19, the lower end of which bears against the side of the plunger, near the top thereof, so that a slight downward movement of the said plunger from the position shown in Fig. 1 will carry it below the end of the spring and permit it to spring inward over the top of the plunger, as seen in Fig. 3, thereby forming a stop that will pre- Vent the plunger from moving off the valve. The entire bushing and the plunger it is intended shall be made of glass, and the bushing is made in two parts, as stated, in order that the plunger may be put in its position between the valve-seat and the stop-plate and also to facilitate placing the valve in position. The fiat spring 19 for locking the plunger on the valve is made, preferably, of mica, but other suitable material may be substituted. The spring should project downward in a slightly-oblique direction, as shownthat is, its upper end should beset far enough outside a perpendicular line joining the periphery of the stop-plate 8 and the side of the plunger with the lower end inside of said line that when the plunger drops down on the valve it will bend the free end of the spring outward. By this construction when the plunger passes the end of the spring the latter will spring back to its original position, and thus pass over the top of the plunger.

The operation of the invention is as follows: The bottle is first filled to a point just below the stoppering device, which is then inserted in the neck of the bottle and pressed down until the springs engage the groove 1, thus fastening the bushing in the neck of the botlie, so that it cannot be removed without breaking the bottle. An ordinary cork is then placed in the mouth of the bottle, which is sealed in the usual manner. The valve is held on its seat by the pendent weight and also when the bottle is in an upright position by the weight of the plunger, as shown in Fig. 1. The end of the spring 19 bears against the side of the plunger. If it is desired to empty a part or all of the contents of the bottle, it is inverted 0r tilted, as seen in Fig. 2, whereupon the weight drops on the ring, thus releasing the valve, and the plunger moves up to the stop-plate, the valve is lifted 0E its seat by the liquid or by its own weight, and thereupon the liquid passes through the valve, thence out through the openings in the sides of the plunger, thence around the edges of the stop-plate and between the stop-plate and the top of the openings in the bushing, and thence passes into the plug again and is discharged from the mouth of the bottle. The direction of the passage of the liquid is clearly indicated by the arrows. When the bottle is returned to its upright position, the weight drops down, thus replacing the valve in its seat, and the plunger falls down on top of the valve. When thus disposed, it is impossible to refill the bottle in the ordinary manner. If it is attempted to refill it by forcing or pumping the liquid into the bottle, the pressure will drive the plunger down against the valve with sufficient force to carry it below a part of the end of the spring 19, which will spring over the top of the plunger and thereby lock it in place, while the pressure will have the further effect of forcing the valve more tightly on its seat and making it impossible for anything to pass into the bottle.- Again, if the bottle bejirn-mersed longitudinally in the liquid for the purpose of refilling it the weight will fall sidewise with its head against the side of the ring, thus holding the valve securely on its seat, and the liquid will be prevented from passing the valve. The top of the weight next to the ring is hemispherical. Hence when the bottle is in a horizontal position the hemispherical top drops against the edge of the ring, and if the valve is off its seat, as it might beif the bottle were first inverted, it slips downward, drawing the valve back onto its seat until the edge of the ring is in the angle formed by the top of the weight and the wire link connecting it with the valve, as shown in Fig. 4. The length of the link is such that when in the position indicated the valve will be fastened securely in its seat and shaking the bottle longitudinally and horizontally will not displace it.

The purpose of this invention is not only IIO to prevent the bottle from being refilled, but also to make it impossible to use it in any way or for any purpose more than once. This is accomplished by locking the stoppering contrivance in the bottle, so that it cannot be removed without breaking the bottle.

While it is stated that the bushing with its stop-plate and the plunger are to be made of glass, we do not wish to be understood as limiting the invention to that material, as other substances may be substituted either for the entire article or for parts of it.

The stop-plate serves the double purpose of preventing direct access into the bushing and to hold the plunger in the bushing and limit its movement, but separate con trivances may be used for these purposes.

We claim- 1. In anon-reusable bottle the combination with the neck of the bottle of a cylindrical bushing made in two parts of uniform exterior diameter, the two parts being fastened together and adapted to fit closely the neck of the bottle and prevent the passage of liquid between the sides of the bushing and the neck, and having a packing-ring in the bottom part, longitudinal openings in the sides of the upper part of the bushing, a stop-plate of less diameter than the exterior diameter of the bushing fixed in the bushingat a point just below the upper ends of said openings, a valve-seat in the bottom part of the bushing just below the lower cylindrical end of the upper part of the bushing, a weighted valve and a plunger inclosed in the bushing between the stop-plate and the valve-seat, and adapted to enter the lower cylindrical end of the upper part of the bushing and form a close contact with the sides thereof to prevent access to the valve when closed, substantially as specified.

2. In a non-reusable bottle a stoppering device consisting in the combination of a hollow cylindrical bushing adapted to be inserted in the neck of a bottle, openings therein for the passage of the liquid out of the same and thence back again to the mouth of the bottle, a stop-plate interposed between the passage-ways for the liquid, a valve-seat and weighted valve in the lower end of the bush- 5o ing, a free moving plunger placed in the plug between the valve and the stop-plate and a spring connected with the stop-plate, and extending down alongside of the plunger and adapted to spring inward when the plunger is pressed down below its end and thus lock the plunger on top of the valve, substantially as specified.

In testimony that we claim the invention above set forth we do affix our signatures in presence of two witnesses.
