PROBLEM TO BE SOLVED: To prevent clog and injection of breakable matter and enable satisfactory injection of contents, by forming a filter in the contents-channel of a housing main body so that it is integrated with the housing main body, and by making a plurality of small passage-holes through the filter. SOLUTION: The channel 10 of a housing main body 3 is 2.0mm in inside diameter and a filter main body 13 is fitted and fixed in the channel 10. The filter main body 13 has a cylindrical form having an H-shaped cross-section, and in its central area a disklike filter is provided. The filter is provided with a plurality of quadrangular small passage-holes, and enables contents to flow from the channel 10 of the housing main body 3 to an inside chamber 4. The small passage-holes each are so formed as to have a diameter of 0.1mm-0.3mm which is smaller than the diameter of the orifice 8 of a stem 5 and the diameter of a push-button spray nozzle, and thus the size makes it impossible for a large solid to enter the inside chamber 4. |
