Abstract: A child-proof closure device for containers has an inner cap for securement on the container neck, and an outer cap rotatable on the inner cap between positions in which dispensing apertures in the caps are respectively aligned, to permit dispensing of the container contents, and covered, to prevent such dispensing. A square control projection on the inner cap is normally engaged with a star-shaped opening in the outer cap in one of positions angularly spaced by 45.degree. to prevent rotation of the outer cap, and can be disengaged for rotation by axial inward pressure to resiliently deform the inner cap. A ring of projections on the outer cap can engage in corresponding depressions or in the dispensing apertures of the inner cap.

Abstract: A metered valve assembly for dispensing a predetermined volume of fluid from a receptacle containing fluid under pressure for each actuation of the dispensing apparatus having a valve chamber of predetermined capacity with a check valve controlling the flow of fluid under pressure from the receptacle to the valve chamber and a control valve for discharging the fluid contained in the valve chamber. The valve structures are so characterized that upon the closing off of the control valve, fluid under pressure in the receptacle will lift the normally seated check valve off its seat to fill said valve chamber with fluid under pressure. Upon the actuation of the dispensing apparatus to dispense fluid, the force maintaining the check valve on its seat is progressively increased until the control valve is opened to permit the discharge of that volume of fluid trapped in the volume chamber.

Abstract: An improved type of tip seal for a dispensing arrangement used for dispensing viscous products and the like with the tip seal comprising essentially an inner stem attached to a body portion, an outer stem slidably mounted over the body portion and having an opening which mates with the tip of the inner stem to form the tip seal and a stretchable rubber member holding the outer stem in contact with the inner stem when no pressure is supplied inside the body but stretching in response to pressure to open the tip seal to permit dispensing of material.
