PROBLEM TO BE SOLVED: To open the discharging hole of a cap without deforming the cap near the discharging hole, improve durability, and facilitate assemblage, by constituting such that the free end of an affixture, which acts as a hole shutter when in a rest state, is retracted during a discharging operation. SOLUTION: A dispenser comprises a narrow, long bottle 1 having a cylindrical chamber 2 whose one end is closed by a hermetically movable piston 3, and other end is restricted by a deformable wall 4. On the upper end of the bottle 1, an elastically deformable cap 7, which partitions off a compression chamber 8 together with the wall 4, is hermetically mounted. In the deformable wall 4, a hollow affixture 5 is provided so as to continue from its central part, and the opening 6 made in the hollow affixture 5 can be closed by a tab 10 serving as a non-return valve formed on the inside of the cap 7. When the cap 7 is deformed by being pressed with hand and the deformable wall 4 is elastically deformed downward, the end of the affixture 5 is separated open from a hole 9, to allow the discharge of filling stuff from the hole 9. |
