WALTER A.- STATTMANN, or WILMETTE, ILLINoIs, AssIe-Non TO UNIVERSAL NON- REFILLABLE BOTTLE COMPANY, or CHICAGO, ILLINOIS, a conronAT oN or ILLINOIS.

To all whom it may concern Be it known that I, WALTER A. STATT- MANN, citizen of the United States, residing at lVilniette, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable detail horizontal section on the line 33 of Fig. -1. Fig. 4 is an enlarged detail view partly in section and partly in elevae tion of the valve housing removed from the bottle showing the same in horizontal position.

The main object of the present invention is to provide a valve-housingand valve, adapted to be mounted in thebottle neck for rendering the latter non-refillable, in which the relation of the valve to the housing is such asto causethe valve to bem'aintained seated by its own weight until the bottle neck "has become partially inverted, and in which the valve will seat itself upon returning the bottle to a position approximating horizontal whereby the admission of liquid into the bottle will be prevented.

Another object of the invention is to provide a valve housing which is relatively very small and all parts of which are of such dimensions as to enable the device to be readily made of glass, porcelain or similar vitreous material.

A still further object of the invention is to provide a valve housing which is not required to be surrounded-by an annular space in the bottle neck for the purpose of discharging its contents, and the discharge opening of which is adapted to be sealed by a] small cork or similar stopper.

- NON-EEFILLABLE BQTTLE.

Specification of Letters Patent. P 'mm 15 914 Application filed March 24, 1913.

Serial No. 756,442.

The device comprises the cylindrical valve housing A. which is adapted to be suitably mounted in the bottle neck 13 preferablyat the discharge end of the latteiy'and' in any suitable manner to provide a fluid-tight joint between saidhousing and said neck. The end walls C and D of said housing are each provided with central openings, that of the outer end wall being adapted to receive the cork E by means of which the bottle is sealed, and the openingin the inner of said walls being adapted to be maintained normally closed by thefiat disk valve F which rests upon said inner wall around said opening and which is capable of lateral movement in all directions on said seat without uncovering the said central opening. The said valve F is preferably in the form of a truncated cone and is relatively thick and heavy, the base of the cone forming the seating face of the valve, so that that-pop tion ofthe valve which is contiguous to the seat will be heavier than the outer portion opening through the seat when the valve is shifted, but causing the axis of the valve to be shifted materially toward the lower side I of the opening when the bottle is tilted, the

result being that in such tilted position, there will be a radical difference in the amount of valve overlap with respect to said "opening in favor of the lower portion of the valve. Consequently, any attempt to pour liquid from the bottle when the latter. is tilted causes the upper portion of the valve to be pushed away from the seatythus forming the passage-way through which the liquid passes at the top of the opening and providing a relatively .free pouring operation, the particular location of the passage way being such that the entrance of air required to provide for such free operation can be readily had.

The housing A is provided with a conical I recess, the base of which is provided by the i inner end wall D, the basal angle of the walls G of the recess being less than that of the valve. The said housing A is-further provided between its ends with what may be termed a guard wall H which is supported in alinement with the central openings in the end walls C and D and is adapted to prevent the insertion of a wire or other device for engaging the valve and maintaining the same unseated for purposes of refilling the bottle. The said guard H may be variously constructed to perform the function indicated without departing from the invention which does not relate to this detail of construction except in so far as said guard plate affords a stop for limiting the movement of the valve F oil its seat.

As shown in the full line position of F ig. 1, the valve F is free to move laterally on its seat in any direction, the seating face of the valve however being of an area which will prevent the valve uncovering the opening in the end wall D during such movements. As the bottle is tilted toward the horizontalythe valve will move until it contacts with the lowest point of the recess wall G, the contact being solely at the outer edge of the valve, due to the difference in the basal angles of these parts. As a result, the support of the valve is at such outer edge so that substantially the entire weight of the valve is exerted in a direction to retain the valve seated, and this condition will be maintained when the bottle is in a horizontal position as shown in dotted lines in Fig. 1. In fact, this position will not change until the bottle has been tilted beyond the horizontal a distance suliicient to carry the center of gravity of the valve outside of such edge support, whereupon the valve will tilt until it contacts with the guard H, the latter limiting the tilting movement of the valve, this being the position shown in Fig. 2, a position in which the contents will be freely discharged from the bottle. As the bottle returns to its nornal position the valve F will tend to seat itself as the bottle approaches the horizontal, due to the shifting of the center of gravity to a point between the point of edge support and the seating face.

By reason of the simplicity of this construction I not only attain the object desired, that is, to cause the valve to seat readily and before the bottle attains a posi tion at Which liquid would flow into the same by gravity, but Iain thereby also enabled to make said housing and valve of glass or other vitreous material, which is very desirable and in many instances absolutely essential to the use of the device commercially.

I claim as my invention:

In a non-refillable bottle, a valve housing having openings in its respective end walls, a valve-seat surrounding the opening in the inner end wall, a disk-valve of less diameter than the valve seat controlling the lastnamed opening; and freely movable on its seat laterally of the same in all directions without uncovering said opening, the said valve'consisting of a truncated cone resting at its larger end on said seat, the circumferential wall of the housing tapering convergently from its juncture with said seat at an angle more acute relatively to said seat than the taper of the eripheral edge of the valve, whereby as said valve moves laterally on its seat only the annular outer corner thereof will contact with said tapered wall of said housing thereby throwing the weight of the valve toward its seat as the bottle is positioned to discharge its contents until the bottle neck is lower than the body and causing said valve to become seated before the bottle is returned to horizontal position, the point of contact between the valve and housing constituting a fulcrum on which the valve turns in opening and closing, and a baflie plate within the housing between the respective end walls thereof against which the outwardly swinging edge portion of the valve strikes to limit the movement thereof, there being openings between the baflle plate and the circumferential wall of the housing out of alinement with the first-named openings.

In testimony whereof I have signed mv name in presence of two subscribing witnesses.
