NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Application filed May 15, 1915. Serial No. 28,394.

To all whom it may concern:

Be it known that I, SAMUEL F. LEAGER, a citizen of the United States, residing at Spotswood, in the county of Middlesex and State of New Jersey, have invented a new and useful Non-Refillable Bottle; 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.

This invention relates to an improved non-refillable bottle, and an object of the invention is to provide a device of this nature, comprising simple, eflicient and practical features of construction comprising a stopper and suitable valve mechanism in the stopper to prevent the refilling of the bottle.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a vertical the neck of a bottle, showing the improved stopper and valve mechanism in section, for preventing the refilling of the bottle. Fig. 2 is a vertical sectional view through the neck of the bottle, showing the neck inverted, and the position of one of the valves as the fluid is leaving the bottle. Fig. 8 is a view similar to Fig. 2, showing the position of one of the valves, when an attempt is made to fill the bottle with fluid under pressure. Fig. 4 is a sectional view on line 4-4: of Fig. 1. Fig. 5 is a sectional view on line 5-5 of Fig. 1.

Referring to the drawings, 1 designates the portion of the body having the usual neck :2, which receives the glass stopper 8, the contracted portion 4 of which has a cork band 5 surrounding the same, which fits between the contracted portion and the inner wall of the neck. The reduced or contracted portion of the stopper 3 has a cylindrical recess or bore 6 extending partially transversely, in which recess or bore a cylindrical pin 7 is seated, there being a coil spring 8 interposed between the pin and the inner end 9 of said recess, so as to hold the pin in the recess 10 of the inner face or wall of the neck of the bottle. When inserting the stopper the pin 7 is held depressed against the action of the spring 8, and just so soon as the reduced or contracted portion of the stopper enters the neck 2 sufficiently to cause the recesses (S and 10 to register, the pin 7 will be thrown in engagement with the recess 10, thereby the removal of the stopper. The lower portion of the reduced part of the stopper is provided with a cylindrical chamber 11, and fitting the extreme lower portion of the chamber and provided with a glazed joint at 12 with the chamber is a glass disk 13 provided with an opening 1 1. The enlarged portion 15 of the stopper has a passage or opening 16 extending vertically, and a laterally or horizontally extending passage 17, which merges into a second vertical passage or opening 18. These passages 16, 17 and 18 are arranged, as will be noted, to form a continuous passage, but angular, owing to the transverse portion 17, thereby preventing an instrument, wire or the like from being inserted sufiiciently into the chamber 11, in order to manipulate the valve member so that the bottle could be refilled. The upper wall of the chamber 11 is dished or provided with a depression 19, to receive the glass ball weight 20 when the bottle is inverted. A glass disk constituting a valve 21 is arranged in the chamber 11, so as to cover the opening 14, and secured to the glass disk valve 21 by means of the wedge shaped projection or lug 23 is a cork disk 2 1, on which the glass ball weight 20 engages. The adjacent engaging surfaces of the disk valve 21 and the disk 13 are ground suitably so as to firmly and squarely engage, and in case any fluid that may accumulate on the engaging surface of the disk 13 will cause the glass disk valve 21 to seal tighter. When inverting the bottle as shown in Fig. 2, to empty the contents or a portion thereof from the bottle, the glass ball valve seats in the depression or dish portion 19 of the top wall of the chamber 11, whereas the cork disk with the glass disk valve 21 rests upon the ball, the pressure of the fluid in the bottle when inverted acting to unseat the disk valve 2l,'thereby permitting the fluid of the bottle topass out through the passages 16, 17 and 18. However, when an attempt is made to refill the bottle, by inverting the same and forcing fluid under pressure thereinto, the fluid will act to force against Patented Feb. 23, 1916.
