Abstract: A device for metering flowable material is formed from two components which are movable relative to each other. The relative movement of the components varies the width of a gap between the components to control the flow of material through the gap. One of the movable components carries a rotatable element to direct the flow of material towards the gap, and a guide element is provided to direct propelled material into the gap. The rotatable element is preferably a disk, and the gap is a channel located proximate to the periphery of the disk. An element mountable to and rotatable with the disk can be provided to act on and reduce the size of solid or semi-solid material carried by flowing fluid to permit such material to flow through the device.

Abstract: A method and apparatus for treating the blade of a razor head by applying a non-foamable liquid lubricant and solubilizer mixtue via an aerosolization system directly to the razor blade immediately before shaving such that shaving can be performed in the absence of first applying any shaving preparation directly to the area to be shaved.
