PROBLEM TO BE SOLVED: To normally spray contents and improve usage by providing on a jetting face of a spraying part a projecting part which projects in an emitting direction and also by forming a jetting orifice in the projecting part. SOLUTION: By the operation of pressing the button 2 of a spray device 1, the valve 3 of the spray device 1 opens, contents 6 filled in a spray main body 5 are urged by a propellant 8 and sprayed outside from a spraying part 17 provided in the button 2 of the spray device 1. The spraying part 17 is provided in the vicinity of its jetting orifice 71 with a projecting part 72 which projects from a jetting face 70 in an emitting direction. The shape of the projecting part 72 is a frustum formed by cutting off a top portion from a plane parallel to a base being in face contact with the jetting face. Also, in the center of the projecting part 72 of the frustum shape, the jetting orifice 71 is provided. The provision of such a projecting part 72 prevents the contents 6 sprayed from the jetting orifice from sticking to the periphery of the jetting orifice 71 during spraying and also from clogging the jetting orifice 71. |
