DETAILED DESCRIPTION

FIGS. 1A and 1B show a disposable razor 10. The disposable razor 10 has a handle 12, a neck 14, a blade portion 16, a frame 18, a bracket 20 and a manual control element or pad 22. The assembly of the blade portion 16, the frame 18, the bracket 20 and the pad 22 forms the head 24 of the disposable razor 10. The blade portion 16 and the frame 18 may be collectively referred to as a razor blade element 26.

The pad 22 is mounted behind the blade portion 16 and the frame 18 via the bracket 20. The pad 22 allows the user to place his or her fingers on the back of the head 24 when using the razor 10. The pad 22 is resilient such that it is comfortable for the user. Alternatively, the pad 22 may be a rigid element. The pad 22 is mounted on the back of the frame 18 by the bracket 20. The bracket 20 provides an opening that allows cut hair to wash through the back of the blade portion 16. The pad 22 is manufactured from a thermoplastic material, for example, injection moulded rubber. Other suitable materials may be used.

The blade portion 16 has a number of razor blades. Three blades are shown, but any suitable number of blades may be used. The blades of blade portion 16 are supported by the frame 18. The blades are stationary relative to the frame 18. The blades are parallel to each other. A precision blade may also be mounted on a top surface of the frame 18, bracket 20 or pad 22.

The neck 14 joins the handle 12 to the head 24. The neck 14 is connected to the handle 12 at a first end of the handle 12. The neck 14 attaches to the head 24 at the frame 18. The neck 14 is attached to the frame 18 by a clipping mechanism. The clipping mechanism may be a click-fit mechanism. The neck 14 has clipping arms that are received by slots in the frame 18. This allows the head 24 of the razor 10 to be attached and detached as necessary. Alternatively, the neck 14 may be attached to another part of the head 24, for example the bracket 20 or the pad 22. Other suitable attachment means may also be used. The neck 14 is pivoted to allow rotation of the head 24 relative to the handle 12.

The handle 12 is wider and shorter than most existing designs. The handle 12 is ergonomically designed to sit in the palm of a user's hand (this is shown, for example, in FIG. 3B). In profile, one side of the handle 12 has a concave surface while the other has a convex surface. In preferred embodiments the structure of handle 12 is asymmetrically curved along an axis that runs from the first end of the handle 12 to the second end; this can follow the palm of a user's hand. This is achieved by making the curvature of the handle more pronounced towards the first end of the handle 12 than the second end. The handle 12 is manufactured from plastic or rubber. Other suitable materials, such as ceramics, metal or wood, may also be used. The handle 12 has a first end that is wider than the main body of the handle 12. This allows the first end of the handle 12 to sit comfortably between the thumb and fourth (ring) finger of the user. This provides grip and leaves the second (index) and third (middle) fingers of the user free to exert pressure on the head 24. This provides enhanced control to the razor blade head via the application of gentle pressure on the manual control element. Furthermore, the curved profile of the handle allows the user to hold the razor comfortably with fingers positioned on the pad to flexibly control the movement of the head and exert enough pressure on the pad to ensure a close and accurate shave. This combination of the handle 12 with the razor blade head 24 allows the precise application of pressure in the requisite direction, from the pad 22 and bracket 20 through to the back of the razor blade element 26, thereby improving control of the razor blade head. In one example, the pad 22 has cut outs which enable the rotation of the razor blade head to rotate relative to the handle 12.

The handle 12 also contains a hollow cavity at its interior, which allows a fluid (i.e. a liquid or a gas) that is less dense than water to be inserted. The cavity may also be filled with a solid that is less dense than water. The cavity could be filled with air or foam, for example. This allows the razor 10, when assembled, to float in order that it can be easily accessed by a user when placed in a pool of water, for example in a sink or bath.

The handle 12 has a second end, opposite to the first end. The handle 12 is shorter than current stick designs. This allows the second end to sit in the palm of a user's hand when in operation. The second end of the handle 12 is shaped to allow the handle 12 to stand unsupported on the second end. This keeps the head 24 of the razor 10 clear of any contaminated surfaces. This allows the blade portion 16 to remain clean, thereby improving personal hygiene. The second end of the handle 12 is dish-shaped in order that it may stand upright on a rim. Alternatively, the second end of the handle 12 may be flat in order to allow it to stand upright. Alternatively, the second end of the handle 12 may have one or more feet that allow the handle 12 to stand upright. The feet may be suction pads that allow the handle 12 to be attached to a surface. Other suitable configurations of the second end of the handle 12 may also be used.

In one configuration, the second end of the handle 12 is concave such that, when placed on its second end, the handle 12 is supported upright by the rim of the concave second end. Furthermore, the concave end of the handle 12 provides a drainage channel into the handle of the razor such that, when the handle 12 stands upright, water does not collect around the base of the razor, as can be seen in FIG. 1A.

When the second end of the handle 12 is concave, it may be grooved to allow the placement of a user's fifth (little) finger. In this case, there is also a well, or depression, 28 on the convex side of the handle 12, towards the first end of the handle 12, for placement of the user's thumb. This can be seen in FIG. 1B. This improves the comfort of the shave when the user is shaving against the direction of hair growth on their face, or when the user is shaving another part of their body.

A more detailed depiction of one configuration of the head 24 of the disposable razor 10 is shown in FIG. 2. FIG. 2A shows an isometric view of the bracket 20, with an elongate portion 30 and support columns 32. The bracket 20 is of a generally E-shaped cross section, although other suitable cross sections could be used. The support columns 32 extend from the elongate portion 30. Support columns 32 extend perpendicular to the axis of elongate portion 30. In this instance, there are three support columns 32, although any suitable number of support columns 32 may be used. The elongate portion 30 and support columns 32 are of square cross section, although any suitable cross section may be used. Alternatively, the bracket 20 may be of a generally M-shaped cross section, where the elongate portion 30 is V-shaped, with three support columns 32 extending from it. This is shown in FIG. 2D.

As shown in FIG. 2B, a first face of the E-shaped bracket 20 is affixed to the frame 18. The opposite, second face of the E-shaped bracket 20 is affixed to the pad 22. The bracket 20 is affixed to the frame 20 and/or the pad 22 by an adhesive. Other attachment means between the bracket 20 and the frame 18 and/or the pad 22, such as a clipping mechanism, are envisaged. The spaces between the support columns 32 define an opening between the blade portion 16 and frame 18 and the pad 22. FIG. 2C shows an isometric view of the assembly of the head 24. The head 24 is moulded as an integral piece. Alternatively, the frame 18, the bracket 20 and/or the pad 22 may be manufactured separately. The head 24 would then be assembled from its component parts, for example, by adhesion or a clipping mechanism such as a click-fit mechanism. Alternatively, the complete head 24 may be manufactured as a single integrated component.

FIG. 2E shows another configuration, where the bracket 20 and the pad 22 are formed as an integral piece. In this way, rather than an E-shaped bracket as previously described, the pad 22 clips to corresponding attachment means on the frame 18 of the razor blade element 26. This is by way of exposure clips and corresponding bars on the frame 18 and/or pad 22. These clipping means are another example of the bracket 20. This provides for a more simple assembly of the parts that make up the razor blade head 24. As can be seen from FIGS. 2D and 2E, the opening between the blade portion 16 and the pad 22 is maintained such that cut hair may wash through the back of the blade portion 16.

In operation, the opening defined by the spaces between the razor blade element 26 and the pad 22 allows water or air to wash through the blades of blade portion 16 and clean away cut hair. The pad 22 has grooves 34 designed to receive the user's fingers when in operation. In one configuration, the pad has two grooves 34 to receive the second (index) and third (middle) fingers of the user. This improves comfort. This configuration allows the user to apply pressure to the frame 18 via the pad 22 and the bracket 20. The force is transferred from the pad 22 to the razor blade element 26 via the bracket 20. The direction of the force is shown, for example, by the arrows in FIG. 2C.

Handling of the razor 10 is shown in FIGS. 3A to 3C. The configuration of the razor 10 allows the handle 12 to sit in the palm of the user's hand. In operation, the user places his or her fingers on the pad 22 mounted on the back of the frame 18. The user applies pressure to the pad 22, which is transferred through the bracket 20 to the frame 18 and the blade portion 16. As the fingers of the user are on the back of the head 24 when in operation, the user may apply more pressure to the head 24 and blade portion 16. This improves the closeness of the shave. In addition, the fingers in this position allow the user to have more control over the head 24 when shaving, improving accuracy. The pad 22 also protects the fingers of the user from the blade portion 16.

During or after shaving, the user may run water through the opening provided by the bracket 20 between the razor blade element 26 and the pad 22. The water runs onto the back of the blade portion 16. This clears any cut hair that is stuck between the blades, preventing the gaps between the blades becoming blocked. Alternatively, the user may apply water to the front face of the blade portion 16 which washes through the blades and out of the opening provided by the bracket 20.

FIG. 4 shows a further application of the pad 22. In this case, the pad 22 is an inflatable pad 36. The inflatable pad 36 may be self-inflating. The inflatable pad 36 has a number of holes 38 that allow air to escape from within the inflatable pad 36 when pressure is applied. Four holes are shown in FIG. 4, although any suitable number of holes may be used. The holes 38 allow the user to pump air from the inflatable pad 36 through the back of the blade portion 16. This clears hair that may have built up between the blades. Alternatively, the inflatable pad 36 may be filled with water, which can also be pumped through the holes 38 to clean the blades, as shown in FIG. 5. This can be done during the shaving process or between shaving processes, in order to clean the blades.

In a further example, the disposable razor 10 can be adapted to include a module for dispensing shaving gel. The shaving gel is stored in an internal reservoir in the handle 12. This internal reservoir is connected to the head 24 via a capillary. The gel is then dispensed from the blade portion 16 or the frame 18 via one or more nozzles. Alternatively, the shaving gel may be stored in the inflatable pad 36 and dispensed through nozzles or between the blades of the blade portion 16 via the holes 38.

In a further example, the disposable razor 10 has blades made of sapphire. Sapphire blades provide a sharper and more durable blade than commonly used materials.

In a further example, the disposable razor 10 has a laser cutting element in place of or in addition to the razor blades. Laser cutting elements provide a more accurate cutting action than mechanical blades.
