ARTHUR CHARLES CAVENDISH LIARDET, OF LONDON, ENGLAND.

NoN-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 665,023, dated January 1, 1901.

Application illedebruary 6, 1900. Serial Noi 4,245. ilio model.)

To tu whom, tmc/y concern.-

Be it known that ll, ARTHUR CHARLES CAV- ENDIsH LIARDET, gentleman, a subject of the Queen of Great Britain, residing at 31 Upper Bedford Plaee,London,England, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to nonrefillable bottles and similar liquid-containing vessels,and has special reference to the class of such botfles in which a float-valve and a plug or baffle in the neck of the bottle are employed. p

According to myinvention I constructv the oat-valve of a hollow hermetically-sealed body with a pointed, conical, or similarlyshaped head, so that when the liquid contents of the bottle are being poured out the incoming air will not be liable to cause the said float-valve toreturn to its seating. Furthermore, the pointed shape of the said valve also insures that it will readily oat and so reach its seating if the bottle be inverted and an attempt be made to insert liquid into the bottle by suction due to a partial vacuumformed inside the said bottle. Suspended from the said float-valve by a flexible connection is a hollow Weight, the said flexible connection eX- tending from the bottom of the said weight to the bottom of the said valve. By connect# ing the weight to the valve at or ueara point at the bottom of said Weight I insure that the said valve will readily leave its seating when the bottle is inclined into a position to pour 4 out the contents Without requiring the bottle to be shaken or otherwise manipulated to cause the valve to effectually open. The float-valve and its weight are mounted in a tube having lateral passages therein and furnished with means for supporting it in the neck of a bottle. The aforesaid plug or baffle is made hollow, and in addition to having oircutous passages in its exterior surface it is provided with lateral passages leading from the interior to the exterior thereof, so that ample space is provided for the entrance of air and egress of liquid from the bottle when the contentsare being poured out.

In order that my said invention may be clearly understood and readily carried into effect, I will describe the same more fully, with baffle with.lateral passages, Fig. l repre-` Senting the bottle in its upright position and Fig. 2 representing it in its tilted position for pouringout the contents. Fig. 3 is an elevation of the plug or baffle detached from the bottle. Fig. 4 is a cross-section of the weight suspended from the fioatvalve, the said section being taken von the line l l of Fig. 2.

a is t-he'bottle, having the interior of its neck b slightly tapered toward the point of junction With the body of the bottle.

c is the tube for supporting the valve and its Weight, said tube being enlarged or flanged at its upper end d to form a seating for the valve. i ee are the lateral holes in said tube. f is a ring of cork or other resilient material which surrounds the upper end of said tube c and by means of which said tube is firmly retainedin position within the neck of the bottle.

gis the valve, and iis the Weight connected therewith by the iiexible connection h. The said valve is formed with a pointed head g', which may be made plain, as represented in lthe drawings, or be formed with longitudinal ridges thereon. The valve, Whether made with Yridges* or plain, must be made of sufficient buoyancy to insure its floating in pure spirits. By providing the valve with the said headv the incoming air entering the bottle when the contents are being poured out will, as already stated, not be liable to cause the valve to return to its seating, as would otherwise be the case if said head were of more or less iattened form. The weight t' is made hollow and has an opening at its upper end 1l' and at its lower end i2, so that the liquid contents of the bottle can freely enter. said weight.

i3 is a transverse piece extending across the opening @"2 at the bottom of the weight to enable the fiexible connection h to vbe readily connected to the bottom of said weight. The weight is preferably made of conical or pear shape, slightly flattened on opposite sides, as

represented in Fig. 4, so that when the bottle is tilted into the critical position-4l. e., the position that allows the weight to fall forward against the tube c the lioat-valve is released and leaves its seating. (See Fig. 2.) When the said weight comes against the tube c, it will not close the latter, but will leave spaces c c' for the liquid to flow past said Weight into the tube or for the air to ascend into the air-chamber of the bottle.` I do not wish to con line myself to the conical or pear shape of the said weight, as it may be made of any other suitable form.

A is the plug or ba'lfle, which is located just above the float-valve in the. neck of the bot tle for the purpose of preventing said valve from being fraudulently operated by a wire or other instrument. Said plug or baliie is made with a cavity A' and has several lateral passages A2 extending from said cavity to the exterior of the plug or baille. It is also formed with annular grooves A3 *A4, which communicate with each other by several ver tical passages or V-shaped notches A5 and with the space beneath said plug or baffle by several vertical passages or V-shaped notches A6. By providing the internal cavity A' and the lateral passages A2 in addition to the aforesaid annular grooves and vertical passages I provide for an increased outflow of liquid and iniiow of air from and to the bottle when the contents are being poured out. Moreover, the said cavity A' in the plug or baffle permits the pointed head of the {loatvalve to enter said plug, so that when the valve leaves its seating it may be supported by the wall of the hollow plug and be prevented from becoming too much displaced from its seating and from becoming locked in its open position by engaging at an angle with the mouth of the tube c or by engaging with other parts of the device within its reach.

That I claim, and desire to secure by Letters Patent of the United States, is-

l. In a non-retillable bottle, the combination of a hollow float-valve having a pointed upper part and a semispherical self-seating lower part, of a tube entirely open at both ends and formed atits upper end with a seat for said valve, and a weightsuspended from said valve by a iiexible connection extending from the lower end of the weight to the lower end of the valve, substantially as and for the purpose speciiied.

2. In a non-rellable bottle, the combination of a hollow float-valve having a pointed upper part and a semispherical self-seating lower part, of a tube entirely open at both ends and formed at its upper end with a seat for said valve, a hollow conically-shaped weight, open to the liquid contents of the bottle and con nected to the valve by a flexible connection extending from the lower end of the weight to the lower end of the valve, substantially as and for the purpose specified.

3. In a non-refillable bottle, the combina tion of a hollow oat-valve having a pointed upper part and a seinispherical self-seating lower part, of a tu be entirely open at both ends and formed at its upper end with a seat fol-said valve, a hollow conically-shaped weight connected to the valve by a flexible connection extending from the lower end of the weight to the lower end of the valve, the said weight being open at both ends to the liquid in the bottle, and being in cross-section of different shape to that of the said tube so as to leave spaces between the sides of the weight and the lower end of the tube when the weight cornes against the end of said tube, substantially as and for the purpose specified.

4. In a non-refillable bottle, the combination ot a hollow float-valve having a ridged pointed upper part and a semispherical self- Seating lower part, of a tube entirely open at both ends and formed at its upper end with a seat for said valve, and provided at its sides,approxiuiately midway of its length, with lateral holes, a hollow conically-shaliied weight connected to the valve by a flexible connection extending from the lower end of the weight to the lower end of the valve, the said weight being open at both ends to the liquid in the bottle and having its opposite sides attened, substantially as and for the purpose specied.

5. In a non-refillable bottle, the combination with an open-ended tube fitted in the neck of the bottle and provided with lateral openings, ot' a hollow float-valve having a pointed upper end and a seinispherical lower portion arranged to seat in and close the upper end of said tube, a hollow open-ended weight suspended from the valve and arranged to seat in the lower end of the tube when the bottle is inverted, and a hollow plug iitted in the bottle-neck above the valve, said plug being provided with a series of lateral openings and a plurality oi. circumferential grooves, the grooves being connected one with the other by grooves or notches, substantially as shown and described.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 19th day of January, 1900.
