NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 708,302, dated September 2, 1902.

Application filed March 27, 1902. gerial No. 100,247. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN J. BENTZ, a citizen of the United States, and a resident of the and exact description.

This invention relates to a means for preventing bottles from being filled after their original contents have been withdrawn.

This specification is an exact description of one example of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional view showing the bottle in upright position. Fig 2 is a similar View showing the bottle tilted. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is a perspective view of the plunger-valve, and Fig. 5 is a similar View of the inverted cupin which the cylinder-valve works.

The neck a of the bottle tapers slightly toward the body I) and has at its upper end a plug 0, of glass or the like, securely and immovably fitted therein. This plug 0 has a centrally-located orifice 0, through which the liquid is drawn off from the bottle. This orifice may, if desired, be closed-by a temporary cork, or any other desired form of closure may be employed, such cork or closure being adapted to be Withdrawn when the contents of the bottle are to be used. Secured rigidly by cementing or otherwise within the tapered neck of the bottle is a correspondingly-tapered cup or sleeve d, the top (1 of which is:

perforated, as shown, and the bottom of which is open. Within the inverted cup d is'the plunger-valve e, which comprises a body portion with exterior grooves 6 running longitudinally along it, and at its lower end the plunger-valve has the valve proper, 6 in the form of a rounding knob. This valve proper coacts with a rubber or other flexible tube f, forming a valve-seat and secured within a contrally-orificed plug g, of cork or like material. This plug is secured rigidly and permanently in the lower end of the neck of the bottle.

\Vhen the bottle is upright, the plungervalve 6 falls to its seat,and it will be impossible to pour liquid into the bottle; but when the bottleis tilted, as shown in Fig. 2, the plunger falls down against the perforated bottom of the-cup d, and the valve-tube f is opened,

thus allowing the liquid to pass freely through this tube, through the grooves e of the plunger e, and out by way of the perforated top d of the cup 01 and the orifice c of the plug 0. In assembling the various parts the plug g is first wedged down tightly in the tapered neck a, the taper permitting the cork plug to be socurely forced into place. Then the plunger 6 is placed in position, and the cup (1 is introduced into the tapered neck and cemented or otherwise secured in place, thus confining the plunger 6 to movement within the proper limits. Finally the glass plug 0 is placed and secured in position.

Various changes in the form and details of my invention may be resorted to at will without departing from the spirit of my invention. Hence I consider myself entitled to all forms of the invention as may lie within the intent of my claims.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. A non-refillable bottle, comprising the combination with the bottle-neck, of a centrally-orificed plug secured in the lower portion thereof, a flexible tube held in the orifice of the plug, a plunger-valve working with the tube, an inverted cup inclosing the plunger-valve and perforated to permit the passage of the liquid therethrough, said plunger-valve having a longitudinal passage for the liquid, and an orificed end plug secured 'in the outer portion of the neck of the bottle.

downward toward the body and the said inverted cup being correspondingly tapered.

3. A non-refillable bottle, comprising the combination withthe neck of a bottle, of a plug secured in the lower portion thereof and having a central orifice, a yielding tube fitted in said orifice and forming a valve-seat, an inverted cup having perforations in its upper portion, said cup being secured in the neck of the bottle above the said plug, a plungervalve mounted in the cup and having a longitudinal passage for the liquid, and a glass or like plug secured permanently in the outer portion of the neck and havinga central orifice for the passage of the liquid.

at. A non-refillable bottle, comprising the roaeoa
