ABSTRACT:
A dispenser is intended to be used with a container of glue that enables pressurized outflow of the glue from an upstanding neck that is threaded to receive the dispenser. A cap threads upon the neck and has an annular top wall. A hollow snout of resilient material projects upward from the top wall and terminates in an opening that defines a valve seat. A guideway in the snout slidably accepts a rod on the upper end of which is a valve. Encircling the lower end portion of the rod is a ring so sized as to be seatable against the top wall of the cap. A plurality of resilient webs are circumferentially distributed in a normal plane and integrally extend between the ring and the rod with each of those webs generally defining a partial spiral and the webs together enabling longitudinal movement of the rod when the ring is seated against the top wall of the cap.
