DEVICE FOR SECURING A VALVE IN THE NECK OF AN AEROSOL VESSEL

摘要

A device for securing a valve in the neck of an aerosol vessel by forming a projection on the setting portion of the valve body, in which a rod is mounted in a housing for movement in an axial direction, and a series of spreadable levers concentric with respect to the rod are secured in the housing for swinging movement in longitudinal planes relative the rod. The rod cooperates with the inner surfaces of the working ends of the levers so that during the working stroke of the rod, the lever spread in a radial direction and form a projection on the setting portion of the valve body. The levers are provided with auxiliary arms, and the rod with a projection adapted to cooperate with the auxiliary arms during the reverse stroke to return the levers to the initial position.
