ROBERT VALLANCE DONALD, 0F SKIPTON, VICTORIA, USTRALIA.

ANTIFBAUD BOTTLE DEVICE.

Application filed November 15, M312.

To all whom i may concern Be it known that I, ROBERT VALLANon DONALD, a subject of the King of Grreat Britain and Ireland, &c., residing at Skipton, in the State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Antifraud Bottle Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others'skilled in the art to which it appertains to make and use the same.

The present invention relates to antifraud bottle devices and my object is to provide a simple, inexpensive construction which shall resist to a considerable extent attempts to refill the bottle after it has been partly or wholly emptied.

In my device the bottle itself has certain modifications whereby to admit and retain in position a dome, under which is a sealing member. The bottle is to be filled before Ithe dome and sealing members are inserted. These may both be inserted together, the rubber or like edges of the sealing member being compressed until it has descended as far as a groove which is described later, when it will expand.

In drawings herewith I illustrate a construction preferred though it may be modified in minor respects while retaining matter which I claim.

Figure 1 is an enlarged sectional side elevation of a bottle neck top, and Fig. 2 is a plan view in section on lines A-B of Fig. 1.

In these drawings 1 represents the bottle neck, with an external annular swelling or thickening 2, and an internal annular groove or recess 3 intended to prevent withdrawal of a circular sealing member which contains a central valve, and which is made of rubber or like suitable material.

5 represents any ordinary cork or stopper which is to be removed when the bottle is to be opened, and 6 is a frangible dome of, for example, glass lwith apertures as 7 which are horizontal and lead to or from the dome interior. The dome has an annular recess 8 into which ts an inner annular flange 9 on the circular sealing member which has also Speccation of Letters Patent.

an outer annular flange 1() to enter the bottle neck recess 3.

The base of the sealing member is a ring 11 the outer part of which rests upon an annular inwardly extending lip or fiange 4 on the bottle neck. The said ring has an inner lip 12 which surrounds a central aperture or the like through which liquid is to be poured out, the upper face of lip 12 having a recess or being adapted for the contact of the under side of the edge of the valve which is marked 14 and which will be raised, as illustrated in Fig. 1, by the pressure of liquid in the bottle when the latter is tilted for the purpose of pouring from it. When the liquid is issuing it passes through one or more holes 7 but leaves one or more other holes for the admission of air to the bottle. To hold the rubber or other edge 10 still more fixedly in the bottle a little cement is at will filled in around edge 16 of the dome thus sealing the bottle neck to the sealing member, and also sealing the dome in place. The valve 14 forms when closed a temporary seal on edge 12 so as to allow liquid to remain above the valve and help to weight it down. To extend this tendency the valve top may be recessed as at 17 a shallow recess only being shown, but in practice a pocket or well of much greater depth would often be advantageous. Any such well or recess would also serve as a means of detecting attempts to introduce liquids as traces of the latter would be retained therein.

Dotted lines in Fig. 1 show raised position of the valve assumed when the table is tilted to discharge liquid.

I prefer that the valve 14 be in one piece, but a distinct valve hinged on as at point 15 could be used and could be of suitable metal. Any suitable lettering or devices may be printed or put on the dome or valve, or both, to indicate the manufacturer, or vender, or so on.

Having described this invention, what is claimed by Letters Patent is:-

1. In combination with a bottle neck having an internal recess, a valve ring having a flange fitting said recess, an apertured dome having means for interlocking With the flange whereby the apertured dome s retained n place, a valve on the valve ring under the apertured dome, and a Seat for he valve on said valve ring.

2. In a non-rellable bottle, a bottle having a neck with an annular recess forming a seat, a valve ring tted in the recess, said t valve ring having a valve seat at its Inner edge, a valve engaglng the Seat and an 1n- Wardly extendlng annular flange on the ring, and an apertured dome having an annular recess to receive the annularrlange of the ring whereby the said Vapertured dome and ring are nterloekngly connected. Y
