' s ec ficat antr original- No. 1,211,984, detedianu i- -e, 1917 reissue and July 30, m7.- Serial m. isaeza to have resulted'in the production of bottles which when once emptiedcould not be refilled by merely pouring a liquid,. back through the mouth of the bottle into the body. or reservoir thereof. Yet, until the present invention, so far as such bottles are known to me, none was proofagainstmethods of refilling which involved the iin- K lnersion of the mouth of an-empty bottle in a liquid attempted .to be introduced therethrough and the creation of a pressure upon the surface of the liquid greater thanthe pressure inside the. bottle. The bottle of myinvention, a practical and convenient embodiment of which is now about to be described, cannot be refilled by any such method, nor indeed by any method known to me, and its function in this res ct, to the best of my information and be lef, depends most largely upon the fact that the cldsing device comprises separatemembers. both of greater and lesser specific gravity than the liquid contents of the bottle and one of which constitutes a valve, said mc-mbers being so arranged relatively toeach other that said valveis -closed through forces of buoyancy when said bottle is tilted beyond ahorizontal position and said valve chamber is filled with a liquid, and closed by action of gravity when said bottle is in all other positions, and being also opened by action of gravity when the filled orpartially filled bottle is inverted; and air enters the dispensing orifice to prevent submergeuce and the consequent creation of forces of buoyancy.

the body of a, bottle of which 11 is; the

shoulder and-12 is the neck, 'I' haveshown placed upon-the upper; edge of the neck 12' an annular-gasket or packing ring 13, made ofcork or other suitable 'packin material, and placed above .this is the. cy ;'ndriformshell orcasing 1ft which is provided with an external shoulder 15 and terminates in a transverse disk or/top ;16;having a central' orifice 17 The shell 14 is ope'mat: the bot: tom,.and is secured to the neck of the bottle: at wthemouth thereof preferably'by, a re-, taining bandylQof metal spun onto.- the-neck of the bottle overthe usual bead 20 and around and above the shoulder 15. onisaid shell. This shell- 14 is also provided interiorly with a series of longitudinal ribs 18.which are continued under the disk-or to 16.

of the shell 14 is ,a seat-21 in the form of aring made of porcelainjor other suitable-material, which-I have shown provided with a depending flange'22 passing downwardly. inside of the gask'et'13. Loose within the shell 14:, above this seating ring and adapted-:to

' rest thereon by gravity, is the preferably disk-shaped body23, of cork or other suitable buoyant material, which constitutes a valve for opening and: closing. the passage through the seating. ring 21. Above the valve or float 23 is loosely placed a weight ing my invention, the parts being in the 24,. of porcelain'or other material heavier;

positions assumed when thebottle is in an than the liquid to be placed in the-bottle.

plan view of the terminals ellor ounte'dabove the gasket or; aching rin The valve or float 23 moves freely between the ribs 18 of the. shell 14: and the weight 24.. rests upon it bygravity when'the bottle is in an upright position. The weight 24.- is

preferably cylindro-conical in form-that is to;say, includes a lower cylindncal portion 24 and an upper frusto-conioalportion 242.

While, as hereinbefore suggested, it is doubtless impossible to definitely determine all ofthe causes of what takes place within the shell 14 under various conditions, I con sider it most important that the contiguous faces ofthe weight 24 and the float or valve 23 should be of such character that these members shall adhere under air pressure when wet and broughtinto contact with each other. With thesarne qualifications,-l also consider it important thatif thematerial of whichthe ring 21 is composed is such that it also will. have a tendency to adhere to the valve 23 when contiguous faces thereof are Wet, then the area of contact surface between we'igh't and valve should be decidedly greater-than the contact area between valve and ringg so that the weight falling under action'of gravity will carry with 1t the valve or float under forces suilicient to overcome the suction between valve and seat.

Arranged within the shell l l above the weight 24, I have shown a combined guard and guide 25 which iscylindrical in external form. This guard and guide member 25 is provided with a frusto-conical recess in the lower face tlie eot' corresponding in contour to the upperportion 24 of the weight 24., whereby the latter may be received within and contained. by the former, a series of ribs 26 being provided on the wall ot'the recess'to prevent air-pressure adherence between weight and guard when wet. I have also shown the guard-and guide 25 provided on its upper face with an annular groove 27, leaving what may be termedan annular latter, in turn, upon the weight and valve,

wall 28 at its outer edge, for a purpose which will be hereinafter set forth. The valve 23 inay' be retained in a closed condition by means of a'stopper 29 having an inwardly. projecting plug 30, preferably of corkor like material, adapted .to fit snugly within the orifice 17 in the top of the shell 14; This plug 30, when the stopper is in place, presses down upon the guard and guide 25, and the and consequently tends to seal the bottle for shipment and initial handling or whenever it is-desired .toprevent egress of the liquid contentsof the bottle whenwholly or partially inverted. I i

In use, the bottle-without the equipment or fitment shown and described-As first filled with the desired liquid. The shell let, with its contained parts properly assembled therein, is then positioned at themouth of the bottle, through the interposition of the gasket 13, andv secured to the bottle-neck by the retaining band 19 in themanner described. The stopper 30 may then. be inserted in the orifice 17 to prevent premature or other untimely dispensation of the contents oi the bottle. When it is desired to dispense a portionor all of said contents, the stopper 30, if in place, is removed and the bottle is inverted, or tipped to a position of inclination substantially as shown in Fig. 2.

The contained liquid now presses upon the normally lowersbut in this position upperside of the cork or float valve- 23, undoubt edly to an extent sufiicient to at least momentarily unseat the valve and wet the contiguous taces of weight and valve. Before can be established in the bottle, the now Wet weight and valve are pressed together, and as the liquid flows from the valve chamber as rapidly as it enters the same the air pressure will cause adherence between these parts I and the weight will hold the valve ofi" its seat, the clearance area being suflicient to permit the free flow of air around said valve and into the bottle to replace the liquid drawn therefrom. It may be that the valvecontrolling forces of gravity applied to the valve through the adhering weight are to a greater or lesser extent augmented by the weight and inipact of the outflowing liquid, but under any circumstances the valve will be retained in an open condition and liquid will flow freely from the bottle. If the bottle is partly emptied and then returned to an upright position, the weight 24: will fall by gravity upon the valve 23 and cause the latter to rest upon the? seat 21 to close the opening into the bottle. lf-the bottle is placed on its side, in the position shown in Fig. 3, the same result will take place because of the cooperating sloping sides of the weight 24 and the guard and guide 25, as the weight will always slide to a lowermost position and in such position will push the valve 23 against the seating ring 21 and effectually close the mouthof the bottle. If the bottle is completely emptied and its any appreciable degree of partial vacuui'n mouth is submerged in a body of liquid,

shown in Fig. 4t, the guard and guide and the weight 24 will both drop to the positions .indicated in that figure both being heavier than liquid now being attempted to introing' therethrough before any liquid can have entered the bottle. No matter" how much pressure be put upon the surface of the liquid outside of the bottle to force the liquid upward into the bottleythe greater the pressure the tighter will be the closure.

The wall 28 of the guard and guide 25 a i and the annular groove 27 inside of said wall 13 duc e, but as the chamber within the shell 14 Q 23'and hold the valve '0 its seat or-eifect I its withdrawal therefrom, in this manner permitting'the introduction .from above of liquid into the body ofth'e bottle. While 'thepossibility of an attempt to manipulate the valve'in'this mannermay beremote, this particular device has been-provided to prevent it, which it does, because when such use of ,aywire or'the' like is attempted, the end ofjthe wire 'is caught in the groove 27. and

against thew all 28 and it cannot be; further forced downward into the shell.
