NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed May 29, 1910. Serial No. 562,478.

To all whom it may concern:

Be it known that I, Josnri-i C. humans, a subject of the King of Great Britain, residing at Jamestown, in the county of Chautauqua and State of New York, have invented new and useful Imprm'ements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to bottles and other like containers. and particularly to stoppers therefor, the object being to provide a novel construction of stopper which will prevent or deter to a maximum extent attempts to refill the bottle after the original contents have been discharged.

The invention consists of the features of construction. combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accom panying drawing, in which Figure 1 is a vertical transverse section through the neck of a bottle embodying my invention taken substantially on the line 1-1 of Fig. 2. Fig. 2 is a similar section on the line 2-2 of Fig. 1. Fig. 3 is a hori zontal section taken on the line 33 of Fig. 1. Fig. +t is a horizontal section taken on the line of Fig. 2. Fig. 5 is a vertical section taken on the line of Fig. 1, showing the sliding valve or cut-off in normal or closed position. F 6 is a view similar to Fig. showing the valve or out off in the open position it assumes when the bottle is tilted.

Referring to the drawing, 1 designates the neck of a bottle or container made of glass or other suitable material which neck is provided at a point below its rim with an annular offset forming a correspondingly shaped channel 2 communicating with the interior of the neck.

A stopper 3 of glass or other material is provided to close the neck, and is provided at its upper end with a lug or finger piece 4: by which it may be conveniently manipu lated during the operation of inserting it. As shown, the stopper comprises a plug adapted to fit the neck and provided at one side of its vertical center with a discharge channel or passage 5 extending entirely therethrough and having a lower flaring end 6 facilitating the entrance of the liquid. Communicating with this passage at a point intermediate of its length is an inclined or diagonally arranged chamber 7, having its upper end facing the side of the bottle whlch is designed to face downwardly when the bottle is tilted for the discharge of its contents.

Fitted to slide within the chamber 7 is a valve or cut-off 8, of less length than said chamber but corresponding in depth and width therewith, said valve being provided at one end with an aperture 9 adapted to register with the passage lVhen the bot tle is in an erect position. the valve closes the passage 5 and occupies, through the force of gravity, its lowest position in the chamber 7. hen, however, the bottle is tilted for the discharge of a portion of its contents, the valve slides in the opposite direction and its port 9 is brought into register with the passage 5 to permit inflow of air and outflow of the liquid.

Through the described operation of the sliding valve, it will be apparent that when the bottle is in normal position or inverted, the valve will close the passage 5 and thus prevent either inlet or exit of liquid, and that the valve will move to a position to open the passage only when the bottle is tilted to a prescribed position. Formed within the body of the plug is a narrow transverse cavity 10 having a rounded top wall and communicating atits base with a slot 11, which slot is of greater width than the cavity but of less length than the same. Formed in the sides of the plug and communicatingwith the end of the base portions of the cavity are preferably angular openings 12 to receive sliding locking dogs 13, which project therethrough into the channel 2 and thus lock the stopper a ainst removal within the neck. These dogs comprise blocks of glass or other suitable material in which are embedded the ends of a substantially semi-circular bowed spring 14; which bears normally against the curved wall of the cavity and is provided with a central coil 15, the arms of said spring being normally forced apart by the coil to hold the dogs or blocks projected. By this means casual retraction of the dogs is prevented, so that the stopper can not be removed from the neck without fracturing or otherwise mutilating the same to such an extent as to give visual evidence to the fact that the bottle has been tampered with.

The slot 11 is provided for the insertion of the dogs 13 and spring 14. In applying them, one end of the spring and the dog carried thereby are inserted at an angle upwardly through the slot into the cavity 10,

bv the tinoers until the lower portions there- 1 of enter the neck, in which position they will remain as the plug is forced downward until they come opposite the channel Zinto which the will. be automatically projected by the action of the spring. The finger piece iis provided for the convenient manipulation of the stopper in insertingit.

A. stopper 5 is provided to close the top of the passage 5 during storage or t1.'ansporta tion Of the bottle.

From the foregoing; description, taken in connection with the drawing. the construction and mode of operation of my improved bottle closure will be readily rnderstood and it will be seen that a type of closure is provided which can be ine:tpensivel manufactured and which will prevent or deter to a maximum degree attempts to refill the bottle.

Having thus described the invention, It claim 1. the combination with a bottle, of a stopper adapted for insertion within the bot tle neck and provided with means for locltinc; it: thereto, said stopper being formed with a vertical discharge passage and an inclined chamber crossing said passage and opel'iing laterally tl'trough one side of said stopper, and a sliding valve arranged in said chamber and of less length than the same, said valve having an outer longitudinally curved edge bearing against the adjacent side of the nec and. being provided at one end with a port to register with the passage when the bottle is tiltedto a prescribed position.

'lhe combination with a bottle. of a stopper comprising a plug adapted to be locked within the bottle neck and having a valve controlled discharge passage said stopper being formed with a cavity opening through its base and with. openings in its si communicating with the base of the savitv, said cavity having a rounded top wall, dogs slidable in said openings and adapted to engage keepers in the neck of the bottle and a bowed spring disposed within the cavity and having its arms connected with the dogs and its central portion arched to conform to and bearing against the rounded. top wall of the cavity and provided with a coil.

in testimony whereof I atlix my signature in presence of two witnesses.
