Document Type and Number:
Japanese Patent JP2005512639
Kind Code:
A
Abstract:
A spray device (20) including a barrel (22) having a bypass (30) and at least two spaced stoppers (32, 34) defining a first and second chambers (42, 44) and a spray nozzle (46). Movement of the first stopper (32) drives the second stopper (34) to the bypass (30) and the fluid in the first chamber (42) into the second chamber (44), mixing the fluid and substance. Continued movement of the first and second stoppers (32, 34) drives the mixture through the spray nozzle (46). The spray device (20) may include a third stopper (170) having a body (170) in the tubular barrel (22) which is moved toward the spray nozzle (46). The movement of the third stopper (170) provides space for the mixture and prevents unpressurized fluid from flowing through the spray nozzle (46). The third stopper (170) includes an axial stalk (174). The stalk (174) may be deformable or the stalk (174) may be separate from the body (170) and the spray nozzle (46) includes a longitudinal internal passage (184) which provides communication with the spray port (54).
