NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Mar. 1d, 1911.

Application filed February 16, 1910. Serial No. 544,280.

To all whom 'it may concern:

Be it known that I, LEO J. LOEFFELMAN, subject of the Emperor of Austria-IIungary, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

rlhis invention has for its object a simple, durable and eflicient construction of non-refillable bottle, the parts of which are so arranged that the bottle may be easily filled with its original contents, and may be easily emptied, while at the same time t-he construction and arrangement of parts will prevent the relling of the bottle.

With this and other objects in view as will more fully appear as the description proceeds, the invention consists essentially in a bottle of this characr provided with an improved construction of valve and an improved arrangement of parts, whereby, as the bottle is tilted to pour out its contents, air will be positively forced into the body of the bottle so as to permit the liquid to flow easily out'and unseat the valve. And the invention also consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to beihad to the following description and accompanying drawings, in which: A

Figure 1 is a longitudinal sectional view of a bottle constructed in accordance with my invention; Fig. 2 is a perspective sectional view thereof, the section being taken on the line 2-2 of Fig. 1; Fig. 3 is a similar view on the line 8 3 of Fig. 1; and, Fig. l is a vertical longitudinal section illustrating a modification.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawing, the numeral 1 designates the body portion of a bot-tle which may be of any size or design and which is provided with a neck formed with an outwardly facing shoulder 2, an outwardly bulged portion 3 above said shoulder, and a nozzle 4. At the base of the nozzle l, the bottle is formed with an inwardly facing annular shoulder 5.

6 designates a valve seat which is preferably constructed out of a rubber ring o-f inverted truncated cone form, the said valve Vseat being adapted to rest on the shoulder 2, the outer or upper edge of the ring being of larger diameter than the shoulder, as clearly illustrated in the drawing. A valve 7 of porcelain, glass or the like is adapted to rest on the valve 6, being shaped to conform to the interior surface of the valve seat and being preferably formed with a bulged lower end 8 which is designed to project through the valve seat so as to assist in holding the valve in place except when it is unseated by the weight of the content-s of the body portion of the bottle. The valve seat 7 is also formed with a nipple 9 which projects upwardly, as shown, and it is designed to hold the lower end of an expansion spring 10 which is interposed between the valve 7 and the inverted cupshaped lower extension 11 of a balie crown 12. The body portion of the baiile crown 12 iscylindrical, as shown, and is encircled by a packing'13 of rubber, cork or the like, the said body portion of the crown being thereby held securely within the neck of the bottle and against the inwardly facing shoul' der 5 thereof and being formed with outlet openings 111 which are two in number in the present instance. The flared lower eX- tension of the crown manifestly serves as a delector, so as to preclude the possibility of reaching the valve by inserting a wire or tmlaol of any character down into the nozz e 4.

The bottom of the bottle is provided with a centrally disposed raised portion 15 in which an opening 16 is formed, said opening 16 being of sufficient diameter to admit the passage therethrough of the valve 8 with its encircling valve seat 6 and the baille crown 12. The opening 16 is filled with a stopper 17 which is preferably rounded on its lower surface so as to presentno angles whereby it may be grasped and withdrawn, said stopper in the embodiment of the invention illustrated in Fig. 1 being formed with an upwardly extending Atube 18 which projects into the interior of the body portion 1, a packing 19 of rubber, cork or the like encircling the tube and engaging the walls of the opening 16, whereby to securely hold the stopper in place. This stopper 17 is formed with an air inlet opening 20 and it contains a piston 21 of glass, porcelain or similar substance which is provided with a packing ring 22 and which is designed t0 fit tightly andA yet moveifreely within the tube 15. Above the piston 21 is a preferably centrally disposed protuberance 24. So far as the upper end 25 of the tube 18 is concerned it is open; but it is normally closed by means of a nipple 26 of rubber or the like which is fitted thereover as clearly illustrated in the drawing and which is provided with a contracted outlet opening 27, the rubber normally holding this opening 27 closed, but yielding when air is forced upwardly in the tube 18 by the relatively -upward movement of the piston 21.

From the foregoing description in connection with the accompanying' drawing, it will be understoo-d that any form of cork or other stopper may be inserted in the noz- Zle 4 and the bottle may then be filled with its contents, but only after the parts before described have been applied thereto. Before -l the bottle has been filled, thebafile crown is thrust through the opening 16 and worked up intothe neck of the bottle so as to be securely held therein against the inwardly facing shoulder 5 thereof.y The valve 7 is then applied, together with its valve seat, the parts being held together in this operation owing to the fact that the valve has the bulged lower extension 8 before mentioned. After the valve Vseat and its valve have been thrust up through the neck, the upper edge of the valve seat will manifestly spring out over the upwardly facing shoulder 2 so as to securely hold the valve seat in place 4with the valve in closed position; thereon. The stopper.17 is then applied, and the packing 19 will then securely hold this part in place. In the operation of pouring outthe contents of the bottle, the bottle is tilted for this purpose. The weight of the content-s of the Y bottle has not enough tendency to unseat the valve 7 against the tension of the spring 10 without any pressure from the inside of the bottle, the spring 10 being stronger than the weight of the valve 7 and tending to hold the same against the shoulder 2 at all times. For this reason I provide the piston 21 in the tube 8. This piston 21 moving toward the open end 25 of the tube 18, will force air from the tube into the body of the bottle,

e giving the necessary pressure to unseat the valve 7. The contracted opening in the nipple 26 will," of course, permit the air to pass from the tube 18 into the body of the bottle, while at the same time the plug'23, with its Y protuberance 24, will tup intoi the nipple and close the opening 25, should an attempt be made to force liquid through the openin 2O and by this way attempt to fraudulently llthe bottle.

yIt is to be understood that my invention is not limited to the exact arrangement and proportions of the parts hereinbefore derubber disk or 'plug 23 which is pref-v erably formed on its upper surface with a scribed and illustrated in Figs. 1 to 3, but that various modifications may be made without departing froln the scope of the invention as defined in the appended claims, and for example reference is to be had to Fig. 4, wherein the body portion and valve structure of the bottle are the same as the body portion and valve structure illustrated in Fig. 1, but the tube 18a is not an integral part of the stopper 17 a, but is separate therefrom and is secured in a recess in the stopper by packing of any desired character. vIn this modification also the tube 18HL is more elongated than the tube 18 before described, and

the opening 25 is formed by a somewhat elongated neck 25a formed on the upper end of the tube; The nipple 26, with its contracted opening 27a, is like the nipple first specified, as are also the air inlet opening 20a, the piston 21a with its packing 22a and the plug 28a with its protuberance 24. As the operation of this modification is exactly like the operation in that embodiment of the invention first set forth, no further de- `neck with an interior valve seat, a valve arranged to be held on said seat, the body portion of the bottle being formed in its bot-- tom with an opening, a stopper fitting in said opening, a tube extending into the body portion of the bottle from said stopper, the stopper being formed with an air opening leading into the tube, and a piston mounted in the tube and arranged to positively force air from the tube into the body portion of the bottle=when the latter is tilted to pour out its contents.

2. A non-refillable bottle provided with an interior valve seat, a valve arranged to be held on said seat, the body portion of the bottle being formed in its bottom with an opening, a stopper fitting in said opening, a tube leading into the body portion of the bottle from said stoppera nipple closing the upper end of the tube and formed with a contractile opening, the stopper being formed with an opening leading into the tube, and a piston mounted to move freely in the tube between the'opening andv its nipple, for the purpose specified.

' 3. A non-reiillable bottle provided with an interior Valve seat, a valve arranged to be held on said seat, the body portion of the bottle being formed in its bottom with an opening, a stopper fitting in said opening,

a tube leading into the body portion of the bottle from said bottle, the stopper being formed with an air inlet openingleading into the tube, a nipple closing the upper end of the tube and formed with a contractile opening, a piston movable in the tube, and a plug interposed between the piston and the nipple for the purpose specified.

4. A non-refillable bottle provided with an interior valve seat, a valve arranged to be held on said seat, the body portion of the bottle being formed in its bottom with an opening, a stopper tting in said opening, a tube leading into the body portion of the bottle from said bottle, the stopper being formed with an air inlet opening leading into the tube, a nipple closing the upper end of the tube and formed with a contractile opening, a piston movable in the tube, and a plug interposed between the piston and the nipple, said plug being formed with a protuberance adapted to close tbe contractile opening of the nipple.

In testimony whereof I affix my signature in presence of two witnesses.

LEO J. LOEFFELMAN.
