Abstract: An aerosol valve assembly, lacking a return spring and dip tube, has a valve housing and a valve body with a lower portion, an intermediate portion and a valve stem. A gasket in a stem groove seals one or more orifice openings into the valve stem except on valve actuation. The valve housing has a lower wall with a central opening for the valve body lower portion to enter to stabilize the vertically acting valve; and, a plurality of product delivery openings positioned about the central opening. A stroke-limiting surface on the valve body prevents the gasket from completely escaping the stem groove on valve actuation. When valve actuation ceases, the valve is returned to closed position by the gasket acting against the stem groove, and the product acting against the valve body bottom portion and the lower surface of the valve body intermediate portion.

Abstract: An easy-to-open aerosol valve assembly for viscous and semi-viscous products, lacking a metal or plastic return spring and product-carrying dip tube, has a valve housing and a valve body with a lower portion, an intermediate portion and a valve stem. A gasket in a stem groove seals one or more orifice openings into the valve stem except on valve actuation. The valve housing has an inwardly and downwardly depending lower wall with a central opening for the valve body lower portion to enter to stabilize the vertically-acting valve; and, a plurality of product delivery openings positioned about the central opening. A relatively narrow product flow passage lies between the side wall of the valve housing and the valve body intermediate portion. The valve body intermediate portion overlies the valve housing lower wall with its plurality of product delivery openings. A stroke-limiting surface on the valve body prevents the gasket from completely escaping the stem groove on valve actuation.
