26,053. Baron, R. J. F. S. Dec. 14. Bottles &c., non-refillable.-The bottle &c. has a liquid-discharge chamber 1 provided centrally with a pipe 2, secured in the neck by cork &c. 3, and providing at its upper end a seat for a spring- controlled valve 8. The discharge chamber is provided with a depending socket 5, screw-threaded at its lower end to receive a fixing-nut 6. In the wall of the tube 2 is formed an air passage 12, provided at its lower end with a spring-controlled valve, and terminating at its upper end in an annular chamber 14, through which it communicates, by means of a spring-controlled valve 19, with an annular air-tight chamber 22, connected to the atmosphere by an air-passage 23 provided with a screw-threaded nipple 24 covered by a cap 25 having lateral holes 26. The chamber 14 is surrounded by a glass ring 15, and contains perineable materials, some soluble, such as salt or sugar, and others insoluble, such as cotton-wool, silk noils, peat, or colouring - matters. On the inside wall of the chamber 14, the word 'fraud ' may be printed or secured, and this will become visib'e through windows in a sealing-cap placed right over the bottle mouth when an attempt at refilling results in the solution of the materials in the chamber. To empty the bottle, it is inverted and an air ball or pump is attached to the nipple 25, air being pumped in to raise the valve 16 and create sufficient internal pressure to enable the liquid to open the valve 8. If the pipe 2 is extended to the bottom of the bottle, the bottle may be emptied without inversion. To prevent tampering with the valve, the discharge nozzle is provided with a conical cup 31, having lateral liquid ports. A glass disk 35 and rod 36 are provided to prevent the cup 31 from being perforated. In the modification shown in Fig. 4, the liquid is discharged through the valve 8 by a piston 45 operating in the pipe 2, which is provided at its lower end with liquid ports 48. The chamber ...
