Abstract: The present invention provides a razor with more than one shaving aid element placed in close proximity to one another on the cover of the razor. The provision of more than one shaving aid element in such manner provides a number of advantages such as: delivery of increased volume of shaving aid at the local area; simplification of manufacturing process during razor assembly; provision of different shaving aids in different shaving aid elements. A preferred shape of the shaving aid elements is cylindrical. The cylindrical shape also enhances the function of the razor by providing smoother shaving aid motion. The shaving aid element may be extruded and stored in spools for use in the razor assembly.

The blades have apertures that allow lubricants removed from a surface of a shaver by the cutting edge of the blade to be transported through the blade and supplied to the cutting edge of the adjacent blade or to a skin engaging surface of the cap member, whichever the case may be. The apertures in the blades define flow paths that allow lubricants to reach successive cutting edges or skin engaging surfaces, thereby reducing irritation to the shaver. The blades are spaced apart by spacers that are constructed with passages that allow the free flow of lubricant through adjacent flow paths. The cap member includes passages that allow the free flow of lubricating agents through the flow paths to the skin engaging surface of the cap member.

Abstract: The present invention is directed to a solid polymeric shaving aid strip for a razor cartridge. The shaving aid strip comprises a lubricious water-soluble polymer and a polycaprolactone, and optionally a water-insoluble polymer. It has been found that polycaprolactone improves the fabrication of the shaving aid strip, provides smoother strip surfaces and permits the inclusion of greater amounts of water-soluble polymer in the strip. It has also been found that a shaving aid strip which contains polycaprolactone releases more shaving aid during use and has better structural integrity and less swelling. The present invention is also directed to a razor cartridge which includes the aforementioned shaving aid strip.

Abstract: This relates to an improved skin engaging member for use in razor blade; cartridge assemblies and shaving systems of the wet shave type. In an embodiment, there is provided a two-component, control-release shaving device consisting of(a) a sheath layer made from thermoplastic resins with openings therein and (b) a core region containing internal shaving aids. Potentially, the device can maintain surface appearance, control-release the shaving aids, minimize the degradation of the shaving aids, and prevent the shaving aids from being trapping in a strip. Furthermore, the addition of low-melt additives to the shaving aids becomes feasible and the compatibility between the shaving aids and the shaving aid carrier such as polystyrene in the lubricating strip composite becomes less critical.

Abstract: The present invention is directed to a razor cartridge with a solid polymeric shaving aid strip. The razor cartridge has a blade (one or more) and a skin-engaging portion in proximity to the blade. The skin-engaging portion includes a solid polymeric shaving aid strip having an upper exposed surface which contacts the skin during shaving. The shaving aid strip includes a first exposed lengthwise-extending portion containing a lubricious water-soluble polymer and an adjacent, second exposed lengthwise-extending portion containing a lubricious water-soluble polymer. The first portion contains a greater amount of the lubricious water-soluble polymer than the second portion, and the first portion is adapted to wear at a faster rate than the second portion during shaving. This construction enables the strip to release more of the lubricious water-soluble polymer for a longer time period (i.e., for more shaves) than conventional shaving aid strips.

Abstract: Manual razor blade shaving devices each feature a razor head structure with sharpened razor blade strips positioned between a pair of large-area non-shaving pressure-applying pads, called glides. These side-located glides, in combination with front and rear blade guards, provide a razor blade shaving head with an effective skin-shaping and guarding system for safely shaving soft pliable contoured skin surfaces, such as the underarm areas. The glides serve as pressure pads to allow significant non-shaving forces to be applied to the pliable skin and subcutaneous body tissue near the razor-sharp blade edges so as to reshape the skin to be shaved to match more closely the razor blade edge profile. This new razor head architecture thus reduces nicks and scratches in sensitive skin areas, like the underarms, by lowering the forces applied to the skin through the blade edges, while providing for closer shaving. The new razor heads are used with conventional T-bar razor handles and head connection arrangement.

Abstract: A shaving unit includes a composite that has a surface for engaging the user's skin. The composite includes adjacent lengthwise-extending portions, each containing a shaving aid.

Abstract: The present invention is directed to a lubricating shaving aid on a shaving razor or a shaving cartridge to reduce frictional drag between a razor blade edge and a shaver's skin and to provide a lubricating film on the shaver's skin during wet shaving. The lubricating shaving aid comprises a water soluble component and a water insoluble component and is formed such that the water insoluble component is released as the water soluble component dissolves upon exposure to water. The invention further discloses a method for making the same from an aqueous dispersion of water, a water soluble component in solution, and a dispersion of a water insoluble component dispersed in the water and the solution of the water soluble component.

Abstract: Manual shaving devices for shaving underarm areas and other small contoured skin surfaces. Each device has a head structure contains one or more razor blade strips between two non-shaving side glide surfaces. In preferred embodiments, the head structure has exposed blade strips about 12 mm to 25 mm (0.5" to 1.0") long, and glide areas each preferably 6 mm to 12 mm long. The blade strips may be straight or curved. The glide areas are preferably rounded with rounded edges, and may smooth or textured. Each device helps facilitate safe shaving of skin surfaces that are soft and pliable by allowing the user to apply, through the glide areas, a non-cutting force to the general area of the skin surface being shaved. This helps alter the skin contour to more closely match that of the sharpened razor blade edges of the device, which are relatively short in length and only bear lightly against the skin to be shaved.
