Abstract: A discharge cap for discharging a content liquid from a container body includes a cylinder assembly that can be tightly fitted to a mouth portion of the container body. The cylinder assembly includes a cap main body provided with a main discharge cylinder, a discharge cylinder body provided with an auxiliary discharge cylinder that is smaller in diameter than the main discharge cylinder, and a lid body for opening or closing the auxiliary discharge cylinder. Hinge-connections are provided between the cap main body and the discharge cylinder body, and between the discharge cylinder body and the lid body, for allowing a selective opening of the main discharge cylinder and the auxiliary discharge cylinder, thereby readily changing the discharge amount or discharge mode of the content liquid.

Abstract: A manually operated spray device for spraying a liquid in a vessel comprises a cylinder member which includes an upper air cylinder and a lower liquid cylinder, an air piston slidably fitted in the air cylinder, and a suction pipe connected to the liquid cylinder within the vessel toward the bottom thereof. An actuator member is urged upwards and vertically movable relative to the cylinder member; and includes a hollow stem protruding upwards from the liquid cylinder and fitted at its center portion with the air piston, a press head fitted onto the upper portion of the stem, a nozzle hole opening at the side surface of the press head, and first and second passages merging with each other on the upstream side of the nozzle hole. The first passage is communicated with the air chamber on one side of the air piston, and the second passage is communicated with the liquid cylinder through the interior of the stem.
