ABSTRACT:
The invention relates to a device for dispensing a fused material. This device comprises a heating chamber, into which a rod of the material to be dispensed is progressively introduced. A clamping member is arranged so as to catch the rod. When a push is exerted on an end of the rod, the clamping member is carried away with the rod towards the heating chamber while biasing a resilient return element. When a push is no longer exerted on the rod, the last is brought rearwards under the action of the biased return element on the clamping member. This avoids untimely dispensing fused material.
