Description

FIELD OF THE INVENTION The present invention relates to wet shaving safety razors and more particularly to shaving razor systems that have a shaving razor cartridge mounted to an ergonomically formed handle for shaving a person's under arms and/or pubic (or bikini) region of the body. BACKGROUND OF THE INVENTION In general, a cartridge or blade unit of a safety razor has at least one blade with a cutting edge which is moved across the surface of the skin being shaved by means of a handle to which the cartridge is attached. Some shaving razors are provided with a spring biased cartridge that pivots relative to the handle to follow the contours of the skin during shaving. The cartridge may be mounted detachably on the handle to enable the cartridge to be replaced by a fresh cartridge when the blade sharpness has diminished to an unsatisfactory level, or it may be attached permanently to the handle with the intention that the entire razor be discarded when the blade or blades have become dulled or in other ways perceived as unusable. Razor blade assemblies have been disclosed wherein cutting edge portions of the blade members are held between skin engaging surfaces which are generally referred to as the guard and cap of the razor blade assembly. The guard contacts the skin in front of the blade member(s) and the cap contacts the skin behind the blade member(s) during a shaving stroke. The cap and guard may aid in establishing the so-called “shaving geometry”, i.e., the parameters which determine the blade orientation and position relative to the skin during shaving, which in turn have a strong influence on the shaving performance and efficacy of the razor. The cap may comprise a water leachable shaving aid to reduce drag and improve comfort. The guard may be generally rigid, for example formed integrally with a frame or platform structure which provides a support for the blades. Guards may also comprise softer elastomeric materials to improve skin stretching. Consumers shaving the pubic region of the body has been steadily growing market segment among women and men over the last several years. Products for the removal of unwanted hair from the body have been commercially available for many years. However, there are limited options available that specifically designed for pubic area shaving. The designs for shaving razors have focused primarily on facial and leg hair removal. These designs restrict how the user can hold the handle of the shaving razor. Other shaving devices that were originally designed to shave the face, such as electric razors and safety razors also do not lend themselves well when shaving the pubic region. The task of shaving the pubic region requires extreme care, patience, coordination, and spatial awareness to avoid cutting the skin or completely missing certain areas. Pubic region shaving is more difficult than shaving one's face because in certain positions the shaving razor or the area being shaved cannot be seen directly or with the aid of a mirror by the user. In addition, the pubic region is typically more sensitive, thus making proper control of the shaving razor and skin contact during shaving even more important. The removal of hair from the pubic area creates a number of challenges for consumers. In particular, the ability to reach and fully remove all pubic hair remains a key unmet need for male and female shavers. The complex anatomical curves and skin mobility in the pubic area present specific challenges. Moreover, the nature of the hair in this area differs from that in other body sites, in terms of elevation angle, fiber shape and diameter. Therefore, hair removal devices available for the legs and underarms are not particularly effective at removal of pubic hair. Commercially available products do not address these particular needs and typically are often simply provided as a generally smaller product to aid ease of handling of the device in the restricted bikini area. There is thus still a need to provide a hair removal device for the pubic hair area, which effectively cuts the hair type in this area in a safe, easy, and efficient manner such that the user of the device is confident during use and thereby ensures improved hair removal end result whilst reducing likelihood of any associated irritation. There is also a need for a shaving razor system having an ergonomic handle to allow for proper control and manipulation for shaving one's pubic region. SUMMARY OF THE INVENTION In one aspect, the invention features, in general a shaving razor handle having a proximal end configured to attach to a shaving razor cartridge. The shaving razor handle has a distal end and an upper surface extending between the proximal end and the distal end. The upper surface has a generally convex profile. The shaving razor handle has a lower surface extending between the proximal end and the distal end. The lower surface has a generally concave profile. A cartridge ejection button is positione
