ABSTRACT:
A plastics material valve for a device for packaging and dispensing a substance. The valve comprises an actuator rod and a valve body, the actuator rod having a passage for passing the substance to be dispensed, the valve comprising closure means suitable for being held in the receptacle by the valve body and suitable for closing said passage, the actuator rod being capable of being displaced in the valve body between a first position in which said closure means close said passage and a second position in which said passage is released to enable the substance to be dispensed, the valve further comprising resilient return means for returning the actuator rod to said first position, the resilient return means comprising at least one bridge of material inter-connecting the actuator rod and the valve body and suitable for deforming elastically and for urging the actuator rod into said first position. The body, the actuator rod and said bridge of material being made by a dual-injection molding technique, the body and the rod being made of a first plastics material and the bridge of material being made of an elastomer, second plastics material, said plastics materials being selected in such a manner that said bridge of material is assembled to the rod and to the body by local melting of material during molding.
