The present invention provides a razor. A body has blade protrusion holes provided in an outer circumferential surface thereof in both directions. A handle unit is configured such that one end of the body is fitted thereinto, and guides the body to a location in which the body is to be accommodated. A blade holder is inserted into the body and guiding coupling of blades such that the blades protrude from the body at different lengths.

A method of manufacturing a liquid dispensing razor by injection molding a gripping sleeve. A fluid reservoir having a port is blow molded. The fluid reservoir is inserted into the gripping sleeve. A handle body is injection molded. A shaving razor cartridge is mounted to the handle body. The gripping sleeve is joined to the fluid reservoir. The gripping sleeve is attached to the handle body. An air gap is provided between the gripping sleeve and the fluid reservoir facilitating evacuation of the delaminating bottle during use.

A personal care bottle with a fluid reservoir defining a chamber for holding a fluid. A fluid port is at a proximal end of the fluid reservoir. A gripping sleeve mounted to the fluid reservoir. The gripping sleeve has a locking tab configured to engage a handle.

A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.
