NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Feb. 17, 1914.

Application filed December 18, 1912. Serial No. 737,400.

To all whom it may concern:

Be it known that I, JOHN C. UHLEIN, a citizen of the United States, residing at \Vatertown, in the county of Jefferson and State of New York, 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, referor force liquid into the bottle.

The invention comprises various details of construction and .combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

1 illustrate my invention in the accompanying drawings, in which Figure 1 is a vertical central sectional view through a bottle made in accordance with my invention. Fig. 2 is a bottom plan view of a cup with a guide member projecting from the bottom thereof. Fig. 3 is a sectional view on line 3-3 of Fig. 1. Fig. 4 is a sectional view on line t& of Fig. 1. Fig. 5 is a sectional View on line 55 of Fig. 1 and Fig. 6 is a bottom plan view of the dish.

Reference now being had to the details of the drawings by letter, A is a bottle provided with a neck B, the lower portion of which tapers slightly, as shown clearly in Fig. l of the drawings, the inner surface of the tapered portion forming a seat for the cup-shaped device D, the outer surface of which tapers slightly and is adapted to be securely held by cement to the neck of the bottle. Said cup has two annular shoulders, designated respectively by letters 'E and F, of dlflerent diameters, the one of smaller diameter and which forms the 'mar-' ginal edge of the opening H being positioned at slight distance below the shoulder E, forming an opening E of larger diameter than the opening H, and for a purpose which will presently be described. The shoulder E forms a seat for the valve N, the under surface of which is formed on the arc of a. sphere so that the contact surface intermediate the valveand its seat may be reduced to a minimum. Said valve seat may be either a sharp corner or very slightly flattened in order to make a tighter joint, an essential feature of the invention being to make the contact surface intermediate the valve and its seat as slight as possible, thereby reducing the friction to a minimum. Said valve is provided with a stem'O which passes through an aperture D formed .in the guide member D which is fastened to the lower portion of said cup, the purpose of said stem being to center the valve and cause the same to seat properly. The stem passes up through the valve and has a float K of cork or other suitable material fastened thereto and which is provided for the purpose of causing the valve to center in the event of the bottle being attemptedto be refilled while held in a horizontal position. The inner wall of the cup is preferably tapered as at Q in order to facilitate any liquid which may be attempted to be poured or forced into the neck in attempt to refill the bottle to pass freely into the cup and act upon the float for the purpose of raising the same to center the valve and facilitate the seating of the same to prevent the liquid passing by the valve into the bottle.

A. disk, designated by letter I, of slightly smaller diameter than the inside diameter of the neck of the bottle, in order to allow suflicient space between the same to permit liquid to pass freely thereby, is provided with three projections I thereon, equally spaced about its circumference and projecting from its under side and which projections, when the disk is adjusted in place, are adapted to rest upon the cup-shaped member D. A member comprising an-inner shell L and an outer-shell T is provided,--.the

outer of which flares as at O and held spaced apart by means of radial partitions J. The inner shell L, it will be noted, is shorter than the outer shell, leaving an open space beneath the bottom of the inner shell L and the bottom of the outer flaring shell and by which arrangement the liquid will be allowed to flow with little interruption between the shells and follow the outward flare and the lower end of the outer shell will pass between the neck of the bottle and the outer edge of the disk I into the "cup D and thence to the valve N, forcing it to its seat.

It will be understood that the parts of my improved valve are so arranged and adjusted that in any attempt to refill the bottle the "inrush of the liquid, which it is desired to be as free as possible in order to effect a quick closure of the valve, will form suflicient pressure upon the valve to hold it to its seat. 7 By reason of the portion of the outer shell above its flaring part 0 being contracted, a suflicient space is allowed intermediate the same and the wall of the neck for the reception of cement in order to hold the shell in place.

In assembling the parts of the invention the valve is placed within the cup with the stem extending through the guard member D and the cup cemented to the inclined surface of the neck, after which the disk is placed within the neck projection I resting upon the upper edge of the cup with the pin which projects from the disk I engaging the hole in the upper end of the cup, after which the shell T is inserted in place and supported by the projection I a slight distance above the disks and after which said shell T is adapted to be held securely in place by cement placed within the space intermediate the circumference thereof and the inner surface of the neck, thereby securely holding the parts together and making it impossible to remove the parts within the neck without severing the neck from the bottle.

By the construction of a bottle made in accordance with my invention, in the event of it being attempted to refill the bottle when submerged in a horizontal position, the smaller opening H, through which the liquid must necessarily flow in order to get into the bottle, will cause a greater depth of liquid to come in contact with the valve and to force it to its seat. The shoulder F, forming the marginal edge of the opening H, it will be noted is spaced apart or positioned below the valve seat a sufficient distance so that the valve will be as far as possible from any portion of the cup D except where itseats upon the shoulder E. I have found from numerous tests that, if the valve has a contact surface upon its seat for a width of over substantially a sixteenth of an inch or if the valve is even in close proximity to another surface, a suction or attraction, when wet, will prevent the unseating of the valve when pouring liquid from a bottle and for this reason valves of this type, when a considerable contact surface obtains between the valve and its seat, the contents of the bottle may not be readily dispensed therefrom. In the present invention, I have sought to overcome this objection by reducing the contact surface of the valve and its seat to a minimum and remove the valve from other contact with the cup. The slightest pressure, therefore, coming upon the inner surface of the valve will cause the valve to unseat and to allow the contents of the bottle to be poured out.

As the seat for the valve is a perfect circle, when the valve is forced in contact therewith, it will touch at all points and make a tight joint, the greater the pressure the better the sealing of the valve. As the stem of the valve is made preferably of a light material and by reason of the float being mounted thereon, any liquid which may be poured or forced into the neck will cause the valve to be raised by the water and closed by any pressure which there may be upon tpe liquid sought to be poured into the bott e. float, the valve would have a tendency to fall by gravity from its seat and liquid might then be poured or forced through the neck while the bottle is in a horizontal position.

By the provision of the disk resting upon and spaced apart from the upper end of the cup member D, ample means is afforded whereby the liquid may be dispensed from the bottle, while, by the arrangement of the concentrically mounted shells, one shorter than the other, a suitable chamber is afforded intermediate the shells and the disk, the wall of the chamber flaring, thus permitting a flow of liquid with little interruption in the event of it being attempted to pour or force liquid into the bottle to refill it, the inner flow of the liquid causing the valve to quickly seat. By this arrangement, it will be noted that any tampering with the valve by means of instruments which might be attempted to be inserted through the neck of the bottle will be prevented.

What I claim to be new is 2- A non-refillable bottle having a tapering neck, a tapering cup seated upon the inner surface of the neck and provided with an annular shoulder in the inner surface thereof, said cup having an opening in the bottom, the inner surface of the upper part of the cup flaring, a convexed valve adapted to contact with the edge of said shoulder, a
