20080266854 | LED Lighting Device - A lighting device includes a housing, multiple light emitting diodes (LEDS), and multiple magnifier lenses. The multiple LEDS and the multiple magnifier lenses are located in the housing. Each of the magnifier lenses corresponds to a different one of the LEDS, and there are less magnifier lenses than LEDS. Each LED that has a corresponding magnifier lens is arranged with respect to its magnifier lens so that substantially all of the light emitted by the LED only traverses its corresponding magnifier lens. At least one of the LEDS emits light that does not traverse any of the multiple magnifier lenses. | 10-30-2008 |
20080250647 | MULTI-USE SHAVING IMPLEMENT - According to one aspect of the present invention, a razor cartridge includes an outer shell, and a support structure. The outer shell defines a primary blade opening and a trimming blade opening. The support assembly is located at least partially inside the outer shell and includes at least one primary blade slot and a trim blade slot. A primary blade is located within each of the primary blade slots in the support assembly such that a cutting edge on the primary blade extends through the primary blade opening in the outer shell. A trim blade is located within the trim blade slot in the support structure such that a cutting edge on the trim blade extends through the trim blade opening in the outer shell. | 10-16-2008 |
20080250644 | RAZOR CARTRIDGE WITH COMB - A multi-function razor cartridge that can be used for hair trimming and normal shaving has a housing including a retractable guard and at least one razor blade having a cutting edge. The razor cartridge also has a comb mounted to the housing that is movable by a user between a non-operable position and an operable position. When the comb is in the non-operable position the razor cartridge can be used for a normal shaving operation. As the comb is moved to the operable position for hair trimming, the guard is retracted so that it will not interfere with the passage of longer hairs between the teeth of the comb. | 10-16-2008 |

20080229583 | Safety Razor with Filament Guard - A razor cartridge is provided with a skin engaging structure at the cap and/or guard surface of the razor cartridge. The skin engaging structure has an array of closely spaced elongated protrusions integrally formed with a substrate. In use, the protrusions produce a pleasant tactile sensation tending to reduce shaving discomfort. The protrusions are formed by closely packed molded flexible filaments that can be less than 0.25 mm wide and have spacing between adjacent protrusions less than 0.2 mm. The protrusions can have a density greater than 5 protrusions per mm | 09-25-2008 |
20080216323 | SHAVING PREPARATION DELIVERY SYSTEM FOR WET SHAVING SYSTEM - A wet shave razor assembly includes a shaving aid delivery system surrounding a razor cartridge. The shaving aid delivery system includes a hydrophilic foam having a water soluble shaving preparation disposed therein. During a wet shave operation, the hydrophilic foam is compressed as the razor is stroked across a user's skin. The hydrophilic foam is an open-cell structure defined by a plurality of supporting elements that cooperate to form tortuous paths. The hydrophilic foam can also include closed cells, or it can be a combination of open cells and closed cells. The shaving preparation is disposed in the paths and/or closed cells. A combination razor cartridge/shaving aid delivery system assembly can be releasably attached to a handle. The razor cartridge may be movable relative to the hydrophilic foam and include a mechanism allowing such movement housed in the handle, or it can be fixed relative to the hydrophilic foam. | 09-11-2008 |
