A pressure pack dispenser (100) for dispensing a product comprises a cylindrical container (401) with a product outlet through which the product is dispensed, a composite piston (408) movably mounted within the container, and a pressurised propellant. The composite piston comprises a first upper piston (409A) coupled to a second lower piston (409B) to permit limited relative axial movement and a viscous sealant material (410) located between the first and second pistons. The propellant comprises a compressed gas which remains in the gaseous phase as the piston (408) moves from a first full position to a second exhausted position, or a mixture of a liquid propellant and a compressed gas selected such that in the full position the mixture is at a pressure greater than the vapour pressure of the liquid propellant. A clearance is provided between the second lower piston (409B) and the container wall (401A) which is filled with the sealant (410) as the composite piston moves to expel product. The viscosity of the sealant and clearance are selected such that a thin film of viscous sealant material (410A) is left on the container wall of the propellant chamber, thereby reducing friction between the composite piston (408) and the container wall (401A). The sealant (410) preferably comprises a mixture of glycerine and starch, and has a viscosity of less than 100 poise and less than 4000 poise at 20° C.

A valve body intended to be fastened to a cup provided with an opening to form an aerosol generator valve, which includes a tubular body closed at one of its ends by a closure wall provided with an orifice and extending along a main axis (a), has two parts which are separate before assembly of the valve, one being provided with the closure wall (32) and with a portion or all of the tubular body (31), and the other being provided with another closure wall (22) provided with another orifice (23) and, where appropriate, with the rest of the tubular body. Each part is provided with a bearing surface (241) and with fastening means (25, 35). The two parts are fastened to each other by their fastening means (25, 35) while clamping, between their respective bearing surfaces (241, 341), the cup at an annular portion (121) located around the opening.

Various implementations of the invention are directed toward a sanitizing door handle and/or components of such sanitizing door handle. Some implementations of the invention are directed toward a manual sanitizing door handle while some implementations of the invention are directed toward an auto-sanitizing door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto an exterior surface of the sanitizing door handle in connection with an operation of the door handle to sanitize the door handle. According to some implementations of the invention, a sanitizing fluid is dispensed directly onto a user's hand(s) in connection with an operation of the door handle to sanitize the user's hand(s).
