A dispensing valve comprising a gate slideable transversely over the outer end of a passage from which is to be dispensed various viscous substances. The gate is slideable substantially at a right angle to the axis of the passage and the gate slide and guide are curved transversely relative to the direction of sliding movement so that the gate will be pulled axially into sealing engagement with the outer end of the passage as it moves thereover. Reciprocation of the gate can be accomplished with the fingers of one hand due to the provision of the cooperating lug arrangement on the slide gate and guide.

A gate dispensing valve assembly comprising a tubular mounting sleeve having a dispensing passage extending therethrough with an inlet end and outlet end, a guide at the outlet and extending radially at a right angle to the axis of the sleeve, and a gate mounted on the guide for reciprocable movement thereon from a closed position, in covering relationship to said outlet end, to an opened position radial of said end to expose an outlet opening at said end, said gate being curved transversely relatively to the direction of movement thereof and said guide being complementally curved transversely, and guide connections between the gate and guide to permit relative sliding for said reciprocable movement of the gate between closed and opened positions, said guide being in the form of a plate extending radially of the sleeve and the sleeve having its outlet opening at the plate, said gate being in the form of a plate, both plates being in close slideable contact, said guide connections comprising channel guides on side edges of the gate plate which slideably receive side edges of the guide plate; means for sliding the gate plate on the guide plate by gripping with the fingers, said means comprising a radial extension on the gate plate having radially-spaced inner and outer finger lugs, and said guide plate having a guide and finger lug through which said extension slideably projects and which is located with said outer lug adjacent the guide and finger lug when the gate plate is in the closed position but with the inner finger lug adjacent the guide and finger lug when the inner lug is squeezed towards the guide and finger lug by fingers engaging the guide and finger lug and said inner lug to move said valve plate to the opened position, said outer lug and said guide and finger lug being engageable by fingers to move said valve plate to the closed position.
