A toothpaste discharging device for a wall is provided to apply the principle of a cylinder and a piston, to have a simple structure, and to reduce the manufacturing cost. A toothpaste discharging device for a wall includes a casing, a piston type button member(20), a cylinder(30), an air inflow portion, air passing portions(32a,32b) and a returning spring(40). The button member is inserted into a button insertion portion of the casing. The cylinder is installed inside the casing, connects a toothpaste vessel and the button member, and makes the button member slid when the button member is pressurized. The air passing portion is formed at the end of the button member to make the air flowing in through the air inflow portion pass toward the toothpaste vessel. The restoring spring is installed in the cylinder to restore the button member. |
