Abstract: Disclosed is a method and apparatus (10) for dispensing powdered pesticide (13). A housing (11) is separated into an upper chamber (12) and lower chamber (51) by a porous media layer (19). The powdered pesticide (13) is contained within the upper chamber (13) and is fluidized when compressed air enters the dispenser from air inlet line (18). The fluidized pesticide is dispensed through adjustable dip tube (26), outlet line (34) and nozzle (36) when a control valve (50) is activated. Only particles having a size smaller than a predetermined size are dispensed; the remaining, relatively large pesticide particles remain in the upper chamber until physically removed.

Abstract: A packaging and dispensing system provides for separate packaging of two ingredients of which at least one is a liquid and for extemporaneous mixing of the two ingredients at the time of first use. The system comprises a first bottle (2) containing the liquid or solid first ingredient and the neck of which is stoppered by a plug (5, 8). It further comprises a second bottle (9) containing the liquid second ingredient and assembled to the first bottle (2) at its neck. There is also an internal coupling member (11) carried by the second bottle (9) and the end of which is coupled to the plug (8). This coupling is obtained automatically when the two bottles are assembled together. A cap (13)screwed onto the second bottle (9) is coupled to the coupling member (11) so that at the time of first use unscrewing the cap (13) initially displaces the plug (8) and establishes automatically the communication between the two bottles without compromising any sterile conditions that may apply.
