Zusammenfassung:	PURPOSE: To ensure the sealing performance between a mouthpiece and a valve and safely perform the residual pressure disposal after the mouthpiece is re moved, by a method wherein thread grooves are formed on the inner circumfer ential surface of the mouthpiece, a sealing material is attached on the thread grooves and the cylindrical part of a valve is brought into contact with the sealing material. CONSTITUTION: Thread grooves 22 are formed on an inner surface 20 of a mouthpiece 2 of a spray can 1, a sealing material 5 is attached on the thread grooves 22, and the inner circumferential surface of a cylindrical part 30 of a valve 3 to be mounted out the mouthpiece 2 is brought in contact with the sealing material 5 attached on the thread grooves 22, so the valve 3 is mounted on the mouthpiece 2 by a cap 4. Thereby, with the spray can 1 filled with pressure air, a complete air-tightness is ensured as the sealing material 5 is pressed by the pressure air. When the cap 4 is removed to release the residual pressure after liquid in the spray can 1 runs out, releasing of the pressure cart be safely carried out because releasing of the residual pressure beings when the bottom edge of the cylindrical part 30 of the valve 3 passes the bottom edges of the thread grooves 22 which hold the sealing material 5.
