Embodiments of the present invention relate to shaving razors. In particular, embodiments of the present invention relate to shaving razor used for shaving purposes with an aim of achieving a smoother shave. More particularly, embodiments of the present invention relate to the shaving razor which is adjustable in a manner that a better handing of the shaving razor is enabled to control the force applied by razor head to an area which needs to be shaved.
BACKGROUND ART
Over the years, the shaving razor model has evolved to mean any business practice in which a company offers its customers a one-time shaving razor blade model, usually at little or no cost. This one-time shaving razor blade model is usually single edged or double edged. The use of these shaving razor blade models is much more common among men. Before the advent of razors, there was a concept of using water and a sharp tool to remove the hair by pulling the hair out. Razors are commonly made from stainless steel, honed to a razor-sharp edge and coated with even harder materials such as diamond like carbon. The razors are routinely replaced after cutting materials far softer than the blades themselves. Many shaving razor systems have been developed to provide user smooth shaving on the area which they wish to shave. But there have been many issues and challenges which are associated with these modern-day shaving razor systems which have been described in detail below.
US Patent application no. “US10899030B2” titled “Razor handle with a pivoting portion” discloses a razor system having a main body and a pivoting head pivotally coupled with the main body about a pivot axis. The pivoting head includes a base member and a cover member that over lies the base member in a mating manner. The cover member includes a face defining at least one exterior opening and the pivoting head can have an interior compartment in fluid communication with the main body and the exterior opening. The pivoting head can rotate from a first position at zero degrees to a second position at about 45 degrees relative to the first position, and any position there between. The handle of this razor system is not able to orient at 90 degrees from the head, thereby unable to allow grip close to back surface of the pivoting head. Also, one of the major drawback in this razor system design is that it leads to shaving induced irritation and is inableto provide user a smoother shave if the orientation with respect to the razor head goes above 45°.
Another shaving razor system technology involves the use of a shaving razor that can include a razor handle configuration that reduces the propensity for the shaving razor to roll in a user's hand and improves the maneuverability of the razor cartridge during shaving. In addition, the shaving razor can include a biasing pivoting member producing a progressively increasing return torque on the razor cartridge that forces the cartridge into flat contact with the skin thus improving glide and shaving closeness. The cartridge includes a connecting member and a cartridge pivot axis providing an axis of rotation for the cartridge. But the major drawback in this razor system technology is that the shaving razor is that it fails to enable a better handling of the razor to control the force applied by the razor head to the anatomy to be shaved. Due to this, a lack of grip is there which is needed by the user on the anatomy to be shaved to get a smoother shave.
Disposable grooming razors are well known in the art. A typical razor sold today involves a multi-blade cartridge that is mounted on an elongate plastic handle, and the razor is used until the blades become dull. Some razors are completely discarded when the blades become dull, and some razors accept fresh blade cartridges to replace dull blades. The handle and head may be retained for further use after the cartridge is discarded. But again, the biggest challenge with these disposable grooming razors is that they lead to irritation while using the head of these razors on the anatomy which needs to be shaved. These commercially available disposable grooming razors are not designed to enable the user to grab the handle just behind the razor head which leads to inability of the razor to provide smoother shave to the user who uses it.
Thus, there is a need for development of an efficient, convenient, smooth and easy to use shaving razor for shaving purposes that minimizes shaving induced irritations, provides a grip needed by the user on the anatomy to be shaved to get smoother shave and enable the user to grab the handle just behind the razor head which leads to ease of using the shaving razor by the user.
Further, limitations and disadvantages of conventional and traditional approaches will become apparent to the one skilled in the art through comparison of the described system with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.
The summary of certain aspects of the present invention provided below are disclosed by way of example, and are not intended to be limiting. From a consideration of the foregoing problems as already described, a shaving razor for shaving purposes is disclosed which helps in overcoming the foregoing problems in prior technologies.
The present invention provides an effective and reliable approach forproviding users a smoother shave by enabling the users to grab handle positioned normally behind razor head which leads to the shaving razor providing smoother shave to the user who uses it. The present invention provides the shaving razor with the aim of reducing shaving-induced irritation and achieving a smoother shave. The design of the razor enables a better handling of the razor to control the force applied by the razor head to the anatomy to be shaved. The handle of this razor is oriented at approximately 90° angle from front surface of the razor head and allow for a grip close to the back surface of the razor head.
According to an embodiment, the shaving razor comprises a razor head, a razor head cartridge having a plurality of razor blades mounted on a razor blade platform and a rear edge portion and a front edge portion facing opposite to each other and a razor handle having a curved profile which is positioned upwards, deviating away from razor body, wherein the razor handle is oriented at any desired angle as required by a user relative to contact surface of the razor head, thereby enabling the user to grab the razor handle with fingers resting close to rear surface of the razor head. The handle is oriented preferably at a 90° angle relative to anatomy-contacting surface of the head. The range of orientation is 50° to 150°, preferably 65° to 105°, more preferably 70° to 95°. This razor can have a very short handle which can have a 10-60 mm (millimeters) length, preferably 15-30 mm. The portion of the handle connected to the razor head is more or less straight having length of 10-30 mm. The handle can have a 80-180 mm conventional length, and is designed at the conventional length of 110 mm. The shaving razor of the present invention provides the user with just enough space to comfortably grab and manipulate the razor. The handle can be a rod-like component, have a more flattened design with a wider cross section, or any other suitable shape. An additional design feature is included to allow the razor to lay on a flat surface while maintaining the head above resting surface. The handle is connected to back of the razor head, optionally the design includes a pivot articulation with a spring back action to push the head toward the anatomy.
According to one embodiment, the razor handle is having conventional length of 80-180 mm, thereby providing the user enough space to change grip and direction of the shaving razor. The handle has an overall curved profile that is oriented upward that is, going away from the razor body.The contact surface of the razor head is flat or slightly convex with a large radius of curvature. The shaving razor comprising the rear edge portion and the front edge portion of the razor head can be slightly recessed from front face of the razor head. The razor head comprises a frame to protect the contact surface of the razor head from corners of the plurality of blades. The plurality of razor blades comprises spring mounted or support mounted blades which allows movement of the plurality of razor blades within the razor head. The shaving razor also comprises a pivot axis of the razor handle positioned towards bottom surface of the razor head and parallel to the cutting edges of the plurality of razor blades.
According to another embodiment, the handle is designed in a way to lay in a stable fashion when resting on a flat surface such as countertop or table, while maintaining the razor head away from the table. This can be achieved in many different fashions: a flat on the bottom portion of the handle, or two small resting surface/features away from each other, or any other suitable mean. Angle between the front surface of the shaving razor and the distal portion of handle is approximately 90°. The handle is curved in an “upward” fashion going away from the 0° direction defined by the shaving direction. The handle is curved, and has a 65°-95° orientation with respect to the razor head front surface. It enables grabbing the handle just beyond the back surface of the razor head.
