Abstract: 3073. Dimitry, E. L. March 5, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Bottles, non - refillable.-Relates to a non - refillable bottle having a valve casing 12, Fig. 1, rotatably mounted in the neck, and a valve 19 normally held on its seat by means which are automatically released when the bottle is tilted beyond the horizontal. The valve casing is provided with a discharge port 15, and also with a channel 14, which receives the valve when the bottle is tilted, this channel being independent of the discharge p o r t and inclined to the longitudinal axis of the bottle. The portion of the valve casing containing the discharge port is heavier than the other portion and so occupies the lower side when the bottle is tilted, the valve channel 14 being inclined upwards when the bottle is horizontal. In the preferred forms of the invention, the valvelocking means consists of a pin 102, which is loosely mounted in the valve and normally engages a recess in the casing, and is adapted to be released by gravity when the bottle is tilted. Tampering is prevented by a perforated disk 33 surmounted by an annular wall 34 and closed chamber 35 having lateral ports, the disk forming the base of an inverted cap 28 which is secured in the bottle neck by springs 29. Depending from the disk 31 is a pin 32, which enters a recess in the valve casing and forms a pivot on which it may turn. Ports 38, 39 in the cap and bottle neck respectively keep the space above the disk 31 in constant communication with the atmosphere, and so prevent the valve from being raised by suction. Numerous modifications are described in the form and dimensions of the valve casing, in the form of the baffle, and in the valve itself. In Fig. 11, the part of the bottle neck enclosing the valve casing &c. is of substantially the same diameter as the neck proper, and the discharge port is closed at the upper end by a perforated cover 53, the remaining portion of the valve casing being projected upwards to receive the pivot pin 60 depending from the baffle. In Fig. 14, the valve section of the neck is rounded and the valve port 78 is closed by a valve 79 connected by an eye 80 to a segmental arm 81 secured to the valve seat and casing. The remaining portion of the valve casing is solid, the discharge port communicating with the space between the casing and the neck. In this form, the baffle is closed by a cork 95 and is sealed with a crown cork 94. In this form, the discharge port may be formed wholly within the casing. In Fig. 18, the discharge port 100 is placed immediately above the valve. In Fig. 19, a ball 116 is used in addition to the valve, and the ports in the baffle incline downwardly. In other modifications, these ports are inclined upwards. In Fig. 23, the valve proper comprises a ball valve 121 seated on a flexible seat 117 and fixed to the lower end of a rod 122 mounted on a pivot 123 adapted to slide in an inclined groove 120 in the casing. The ball is maintained in a closed position in all positions of the bottle other than a complete inversion.
