<p>A trigger type fluid dispenser (100) according to the invention includes a body (110) having a discharge flow path (111) and a cylinder (112) disposed in parallel with the discharge flow path (111), and a piston (140) in the cylinder (113) is caused to slide by a trigger (130). The trigger (130) is configured so that a hook portion (131) thereof is held to be swingable by the body (110), a turned-down portion (131) of an extension portion, which is an elastic portion (132) integrally extending from a swinging portion (114) of the hook portion (131), is held with respect to the body (110), and a tip end (132e) of the extension portion is positioned to be capable of coming into contact with the hook portion (131). The body (110) is configured so that a cover (120) is installed to form an internal space (R) between the cover (120) and the discharge flow path (111), and a core element (150) is inserted in the discharge flow path (111) and the internal space (R). The core element (150) is integrally provided with a tongue-shaped element (153), serving as a discharge valve, near a discharge port (111a) of the discharge flow path (111), and also integrally provided with a tongue-shaped element (154), serving as a suction valve, in the internal space (R). <IMAGE></p> |
