Abstract: A viscous fluid dispenser having a significant decrease in the number of parts constituting the dispenser and thus having a simplified structure which can be easily assembled and which can function satisfactorily is provided. A first embodiment of the dispenser includes only five parts: a cylindrical body integrally formed with a top plate, a movable bottom lid slidably fitted in a lower end of the cylindrical body, a piston slidably fitted in a cylinder of the top plate and having a discharge pipe, a push button having a discharge nozzle connected to the discharge pipe, and a spring for upwardly forcing the push button and piston. A first check valve for operating a suction hole of the top plate is integrally formed in the top plate, and a second check valve for operating the discharge pipe is integrally formed in the piston.

Abstract: A divisible package box comprising a main sheet and a partition body, the main sheet including a bottom, two side and two cover sections, flaps and a cutting line such as a cutting tape or a perforated line across the bottom section and the bottom flaps, the partition body consisting of two partition members in back to back contact with each other, each partition member including a partition section and two end sections at its ends, the sections and the flaps being defined by score lines for folding therearound. The end sections and the side flaps constitute end faces of an assembled package box so that the inner surfaces of all faces thereof may be completely flat. The assembled package box may be divided into two small boxes along the cutting line and the partition sections which constitute each end face of the divided two small boxes.
