PROBLEM TO BE SOLVED: To enable the prevention of nozzle clogging using an applicator with simple constitution. SOLUTION: In this applicator, a reaction type hot melt adhesive is supplied from an adhesive storage tank 2 for storing the molten adhesive to sprayers 1a-1d through an adhesive supply route 4. A washing fluid storage tank 8 for storing a washing fluid which is not cured by the reaction with water in air is connected to the route 4 through a washing fluid supply route 10 and a change-over valve 12. The valve 12 does not connect the route 10 with the route 4 when the hot melt adhesive is ejected from a nozzle but connects the route 10 with the route 4 through the nozzle only when the nozzle is washed. |
