A fluid dispensing valve used for printing and marking, having a valve body with an end wall which defines an aperture and a spring biased valve element disposed within the valve body to open and close the aperture. A spring element is coupled to the tubular body adjacent the circular wall, the spring element and the wall defining a chamber for receiving a fluid metered through the aperture of the valve body when the aperture is opened, the spring element having at least one aperture communicating with the chamber. A porous member is affixed to the spring element such that the porous member covers the aperture in the spring element. The porous member transfers the fluid received in the chamber to a surface in the form of a printed geometric image. In operation, a printing force applied to the porous member causes the spring element to compress and engage the portion of the valve element thereby pushing a portion of the valve element partially back through the aperture in the open position to allow the passage of a marking fluid therethrough to the chamber to wet the porous member. The porous member has a predetermined rigidity which substantially prevents the porous member from distorting from its predetermined geometric shape under the printing force. The fluid dispensing valve is typically affixed to the open end of a container which contains the fluid to be dispensed. A removable cap is provided for covering the valve when it is not being used.

[ What is claimed is:] [1.] A fluid dispensing valve, comprising:a valve body including an end wall which defines an aperture extending therethrough, and an annular flange extending from a surface of said end wall, said annular flange having an inner groove;check-valve means disposed in said valve body for metering a fluid, said check-valve means including a portion which cooperates with said aperture for a liquid tight seal in a closed position;a spring element including at least one aperture extending therethrough and a flexible annular skirt, said flexible annular skirt being coupled to said inner groove of said annular flange, said spring element and said surface of said end wall defining a chamber therebetween for receiving the fluid metered by the check-valve means; andporous means of a predetermined geometric shape, affixed to said spring element for transferring the fluid received in said chamber to a surface;wherein a force applied to said porous means causes said spring element to compress, thereby engaging and pushing said portion of said check-valve means through said aperture, whereby in an open position fluid passes therethrough to said chamber and through said at least one aperture to wet said porous means, said porous means having a predetermined rigidity which substantially prevents-said porous means from distorting from said predetermined geometric shape under the applied force.
