In a closure arrangement for the outlet orifice of a dispenser of fluid or pasty material having a hollow closure cap (48) which engages over the outlet channel (58) of the dispenser, said cap is produced from an elastic plastic and has at its closed end (54) at least one opening (60) which only opens under the pressure of the material emerging from the dispenser. The closure cap (48) is particularly suitable for a closure and valve arrangement in hand-held devices for the application of hot-melt adhesive. <IMAGE>
