NON-REFILLABLE BOTTLE.

SPECIFICATION formingpart of Letters Patent No. 632,916, dated September 12, 1899.

Application filed May 22, 1899.

To all whom it may concern.-

Be it known that 1, JOHN OREASY, a subject of the Queen of Great Britain, residing at London, England, haveinvented new and usef ul Improvements in Non-Refillable Bottles, (for which I have applied fora patent in Great Britain No. 15397, dated July 14, 1898,) of which the following is a specification.

This invention relates to non-refillable hottles, and has for its object to simplify the construction and increase the efficiency of the same.

According to the said invention I form a seat in the neck of the bottle upon which a disk of glass or other suitable jointing material is designed to bear, and above this disk I place a hollow thimble or cap, of glass or like material, which upon any attempt to introduce liquid into the bottle is carried forward with the liquid and presses the disk against its seat. The cap or thimble is preferably of such size that it will fit the bottle neck, grooves being formed in it to allow of the escape of the liquid.

In the accompanying drawings, Figure 1 is a vertical section through a non-refillable bottle constructed according to the invention. Fig. 2 is a vertical section of the upper part of a bottle with the stopper removed. Figs. 3 and 4 are an elevation and plan, respectively, of the screw-plugfor closing the mouth of the bottle. Figs. 5 and 6 are a plan and elevation, respectively, of the cap or thimble; and Fig. 7 is a View illustrating the position the parts of the stopper assume when the bottle is tilted for pouring out the contents thereof.

a is the bottle, and b is the seat formed in the neck 0. thereof, the said seat being fitted with a ring of cloth 0 to form a good joint.

cl is the disk, of glass or other suitable material which is designed to bear upon the cork ring 0 of the seat 6, andfis the hollow thimble, of glass or like material, which normally rests upon the glass disk d, as illustrated in Fig. 1, so as to close the neck of the bottle. The bottom of the thimble is ground fiat, and the upper face of the disk d is also ground, so that good contact is obtained between the two ground surfaces. The thimble, which is shown separately in Figs. 5 and 6, is prefer- Serial HID-71757701 (No model.)

ably made to fit the neck a of the bottle and is provided with external longitudinal grooves f and with notches f 2 at its upper part.

g is the screw-cap or plug which is of ordinary construction, is screwed intothc internally-screw-threaded upper end of the bottle neck a, as shown in Fig. 1, and is provided with a central hole g, adapted to be closed by a cork The bottle ais filled with liquid before the disk cl and the cap or thimblef are placed in position, the parts being retained in the bottle by the screw-cap g. When it is desired to empty the bottle, the cork g is removed and the bottle tilted, so that the contents thereof force the disk d and the thimble from the seat I), escape through the seat I), and then flow down the grooves f, formed externally upon the thimble f, and the notches f and pass through the central hole g of the plug g. Should any attempt be made to refill the bottle, the thimble receives the liquid introduced and causes the disk d to bear upon the cork ring 0, thereby closing the bottle-neck. The liquid introduced into the thimble will increase its weight and the pressure which it exerts on the valve, and a very light thimble can therefore be employed in this construction.

It will be noted that the thimble is of substantially cylindrical shape and fits the bottle-neck, thus precluding the possibility of inserting a wire or other instrument into the mouth of the bottle for the purpose of raising and holding up the valve. The thimble also acts both as a weight to hold the valve closed and as a float to close the valve. If the bottle is placed in an upright position and an attempt is made to refill the bottle, theliquid introduced will be received into the recess in the thimble, which is itself very light, and the weight of the liquid added to that of the light thimble will hold the disk or valve firmly down on its seat and prevent refilling. 1f 5 the bottle is inverted and an attempt is made to refill it by forcing liquid upward into the bottle, the liquid as it enters the bottle-neck and reaches the thimble will cause the thimble to float, on account of its lightness and also too on account of the fact that the liquid will seal the mouth of the thimble and inclose a body of air Within it. Hence the thinible will float on the liquid and in rising Will close the valve tightly and. prevent any of the liquid from entering the bottle. If the bottle is placed on one side and liquid isin trod need through the mouth, the light Thimble will be moved alongin the neck and made to close the valve.

Having nowparticularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- In a non-refillable bottle the combination with the bottle-neck provided with a valveseat, a valve on said seat and a closing device above said valve provided with a pouring aperture, of a relatively light thimble substantially cylindrical in form fitting the bottleneck between the valve and said closing device, said thiinble havingits exterior provided with longitudinal grooves, and being provided with a central longitudinal recess closed at the lower end of the thimble and open at the upper end, said thi mble having its upper edge provided with notches in line with said 1011- gitudinal grooves whereby on attempting to refill the bottle, the recess in the thimble will receive the entering liquid and increase the Weight of the thirnble upon the valve, to hold it closed, and when the bottle is inverted the entering liquid will seal a quantity of air within the thirnble so that said thiinble will float upward and close the valve,substantially as described.
