ABSTRACT OF THE DISCLOSURE: An improvement of noncontrolling type valve for use in a gas- lighter, a portable cooking stove and other burners, which valve comprises a valve body push-fitted in a recess formed in the top plate of a gas container; and a filter positioned under the valve body to permit a given constant flow of gas to pass to the valve body when the valve opens. The valve is improved acoording to the present invention in that an annular spacer is fixed to the annular inside edge of the uppersurface of said filter, allowing the bottom end of said valve body to contact the remaining center area of the uppersurfaces of said filter. The coplanar position- ing of the bottom end of the valve body with the annular spacer prevents deformation of the filter even if it is exposed to an increased gas pressure, thereby assuring that the gas flows through the filter at a controlled rate all the time.
