PURPOSE:To simplify the constitution of a dispenser body and realize mass production, by forming the dispenser body from inflow and out-flow path separately. CONSTITUTION:A trigger type dispenser body 10 is composed of a dispenser body 12, a cylinder 22, a piston 24 and a trigger 26. The piston 24 and the cylinder 22 are molded separately from the dispenser body 12. The piston 24 with a valve sheet of a secondary valve 88 is fixed stationarily at the upper half 14 of the dispenser body 12. The cylinder 22 with a valve sheet of a primary valve 64 being fitted to the trigger, it is arranged movably for reciprocation at the lower half 16 of the dispenser, interlocking with the swing of the trigger. An inflow path 60 is formed in the cylinder 22 and an outflow path 80 is also formed in the piston 24. A notch 28 is provided the front face of the lower half 16 of the dispenser body. A holding part 36 of a bottle cap base 30 is provided at the lower half 16 of the dispenser body. The bottle cap 20 is fitted at the lower half 16 of the dispenser body 12 and the bottle cap base 30 is held between the rear bottom edge 15 of the upper half and the holding part 36. |
