ABSTRACT:
A dispenser has an outlet nozzle which is reversibly movable by rotation of a control cap from a first extended position, in which adhesives is dispensed as a series of fine spots, to a second retracted position in which adhesive is dispensed as a film using the flat upper surface of the control cap as a spreading tool. The base of the nozzle is joined to the walls of the dispenser by a flexible membrane. The control cap is provided with a centrally located hole, in the flat upper surface, through which the nozzle can protrude, and an internal coaxial sleeve which surrounds the nozzle. The latter is provided with a locating stud which cooperates with a screw groove in the inner surface of the sleeve so that manual rotation of the control cap causes the stud to travel along the groove, thereby causing the nozzle to move between the first and second positions.
