摘要： A razor blade body in the form of a cartridge structure includes a guard member assembled thereon forward of, and extending parallel to, the blade or blades. The guard is of a two part molded structure having an upper portion of elastomeric material with a plurality of upwardly projecting protrusions formed thereon and a lower base portion of rigid plastic material having a downwardly projecting V-shaped cross-sectional portion. A pair of upwardly projecting elements are disposed in spaced relation forming a recess on the blade cartridge structure for receiving the V-shaped base portion therebetween and a latch means disposed in the recess retains the guard member in the assembled position.

摘要： A metered spray device has a container with an open top. A barrel is sealed in the top of the container and extends into the container. An elongated piston is slidably mounted in the barrel. The piston has a central opening running the full length of the piston for the passage of fluid. A check valve in the lower end of the barrel blocks the flow of fluid from the barrel into the container. A nozzle for engagement with a nostril is connected to the upper end of the piston. A spring biased check valve in the upper end of the piston blocks the flow of fluid downwardly into the piston.
