ABSTRACT:
A hand-held sand blasting device, which is particularly useful for treating mall surface areas, such as tooth faces in situ, includes a sand cartridge 20 adapted to be placed in a handle portion 10 of the device and rewardly sealed by a piston 34 which is adapted to be advanced by pressurized air. Part of the pressurized air flows along a longitudinal groove 25 formed in a wall of the handle portion 10 externally of the cartridge 20 and enters the cartridge through an opening 27 provided at a front portion thereof, where the relatively large cross-section of the main portion of the cartridge converges to the substantially smaller cross-section of a feed channel 28. The fine sand 21 is thus fluidized in this area and maintained flowable. Through the feed channel 28, the sand is supplied to a mixing chamber 30 where it is mixed with pressurized air and discharged through a nozzle pipe 33.
