DETAILED DESCRIPTION

[0040] Immaterial modifications may be made to the embodiments described here without departing from what is covered by the claims. In the claims, the word "comprising" is used in its inclusive sense and does not exclude other elements being present. The indefinite articles "a" and "an" before a claim feature do not exclude more than one of the feature being present. Each one of the individual features described here may be used in one or more embodiments and is not, by virtue only of being described here, to be construed as essential to all embodiments as defined by the claims.

[0041] Referring to Figs. 1 - 5, there is disclosed an embodiment of a body forming a razor handle 12 having a first end 14 and a second end 16. The first end 14 of the handle 12 is formed as one part 18A of a quick release connector 18 (see Fig. 8 and 22 for the entire quick release connector 18). The part 18A includes a housing 22 that forms a cylinder opening outward. As shown in Figs. 3 and 4, the housing 22 has a latching component 24 for removably holding a piston in the housing 22. The latching component 24 may comprise an interior groove 26 containing a latching element 28. The latching element 28 may for example be a canted coil spring. The housing 22 may have for example a generally cylindrical shape. The latching component 24 may operate using any suitable releasable latching mechanism such as snap fit joints. Although the housing 22 is shown here as being on the handle 12, the piston part of the quick release connector 18 may instead be on the handle 12 in any of the disclosed embodiments.

[0042] The female part 18A of the quick release connector 18 allows the handle 12 to be connected to a male part 18B (piston) of the quick release connector 18, the male part 18B

being shaped to fit in the housing 22, thus allowing a variety of functional heads to be connected to the housing 22.

[0043] Figs. 6¨ 8 disclose a further embodiment of a razor 10 comprising a handle 12 having a first end 14 and a second end 16 and the handle 12 having one part 18A of the quick release connector 18 at the first end 14. A safety razor head 30 has a razor blade 32 and a piston 34 extending from the head 30 away from the razor blade 32. The piston 34 and housing 22 together form the quick release connector 18, with the piston 34 inserted in the housing 22. The embodiment shown of the quick release connector 18 has a latching component 24 for removably holding the piston 34 in the housing 22 of the handle 12. The latching component 24 may comprise a groove 26 containing a latching element 28. The latching element 28 may be for example a canted coil spring. The piston 34 may have angled outer surfaces or indents 36 corresponding to the latching component 24.

[0044] Referring to Figs. 6¨ 13, an embodiment of a razor 10 may comprise a handle 12 for gripping the razor 10, the handle 12 having a first end 14 and a second end 16, the handle 12 having a core 38 and a removable sleeve 40, the sleeve 40 having a hollow interior shaped to allow the sleeve 40 to slide onto the core 38, and a razor head 30 attached to the handle 12 at the first end 14. The razor head 30 may be a safety razor head or cartridge razor head. The sleeve 40 may for example be made from any type of material to create a variety of decorative finishes including but not limited to polished, chromed, anodized, colored, printed, and including such materials as aluminum, copper, brass, gold, silver, platinum, tungsten, stainless steel, titanium, wood, resin, carbon fibre. The sleeve 40 may be decorated using UV cured inkjet technology, silkscreen technology or application of a printed plastic sleeve. Resin may include any type of poured, cast, or machined synthetic or semi-synthetic organic polymers of high molecular mass commonly called 'plastic'. The sleeve 40 allows users of the razor 10 to change the appearance or shape of the exterior of handle according to preference. In an alternative embodiment, the sleeve 40 may be permanently fixed to the core 38.

[0045] The core 38 may be solid or hollow and may be made of for example metal or resin material. The diameter of the core may be sized to fit the inside diameter of the sleeve 40 to allow the sleeve 40 to be slid over the core. In an embodiment, the portion of the core 38 closer to the first end 14 of the handle 12 may be larger in diameter than the diameter diameter of the sleeve to act as a stop 42 for the sleeve 40. The diameter of the core 38, and the corresponding diameter of the sleeve 40, may vary over the length of the core 38 and sleeve 40.

[0046] The sleeve 40 may include multiple sleeve sections. The sleeve 40 exterior may form any desired shape, including for example round, square, triangular, or ribbed.
The sleeve 40 may be secured to the core by for example gluing, friction, fit or magnetically. The sleeve 40 may also or alternatively be secured in place by a bottom cap 44, attached to the second end 16 of the handle 12, as shown in Figs. 1 ¨ 3. Several views of the bottom cap 44 are shown in Figs. 14 - 17. The bottom cap 44 may be removably fixed to the handle 12 in a variety of ways, including for example by screwing or a snap fit. Bottom cap 44 may for example have an inner groove 46 and a pin element 48. The inner groove 46 may cooperate with a corresponding ridge on second end 16 of the handle 12 to form a stop for the sleeve 40 so that the sleeve 40 does not slide off of the core 38 in use. The pin element 48 may help the user align the bottom cap 44 with the handle 12. The sleeve 40 may incorporate a variety of materials including stones (precious or non-precious), electronic components such as LEDs or electroluminescent wire. The sleeve 40 may have for example an inner radius of 0.278 ¨
0.288 inches.

[0047] As shown in Figs. 6 ¨ 8, the housing 22 of the quick release connector 18 may be covered with a top cap 50. Figs. 18 - 21 show several views of the top cap 50.
Top cap 50 may provide protection for the quick release connector 18. Top cap 50 may slide onto the quick release connector and abut against the first end 14 of the handle 12.

[0048] Referring to Figs. 22 ¨ 26, an embodiment of a razor 20 comprises a handle 12 having a first end 14 and a second end 16. At the first end of the handle 12 is a female part 18A of a quick release connector 18 for receiving male part 18B that is attached to a neck 52 of a cartridge connector 53. The cartridge connector 53 has a body extending between the female part 18A of the quick release connector 53 and an adaptor portion 54 for connecting to a razor cartridge. The adaptor portion 54 has a substantially trapezoidal-shaped cross-section, wherein the trapezoid forming the trapezoidal-shape is an acute trapezoid. The roughly trapezoidal-shape may have non-linear sides or may have more than four edges.

[0049] The adaptor portion 54 may be used to connect the razor handle 12 to a variety of razor cartridges, and for this reason is referred to as a universal adaptor, although it will be understood that universal in this context only means that several cartridge heads may be connector to the cartridge connector. The adaptor portion may be made of a flexible, resilient material to allow different shapes and sizes of razor cartridges to be inserted into the adaptor portion 54.

[0050] Referring to Figs. 6 ¨ 8 and 27 - 36, an embodiment of a razor head 30 comprises a blade 32 mounted to a razor base 58 and a silver coating or strip 60 fixed to the razor base 58 and adjacent to the blade 32. The silver coating or strip 60 may be for example a silver strip running parallel to the razor blade 32 along the razor base 58. The silver coating or strip 60 may be affixed to discrete sections of the razor base 58 which are adjacent to the blade 32.
The silver coating or strip 60 may replace a lubrication strip on the razor base 38. The silver coating or strip 60 may provide a natural antibacterial protection while shaving. The razor head 30 may be any type of razor cartridge with any number of blades. Fig. 27 shows a cartridge head having a silver strip 60, razor blades 32 and wiper blade 62

[0051] The razor base 58 may be the base of a cartridge razor such as for example the cartridge shown in Fig. 27, or a safety razor such as for example a razor base in Figs. 31- 34.
The razor base may have tapered walls 64 to provide swarf clearance. The razor base 58 may be for example 1.015 ¨ 1.025 inches in width, 1.625 ¨ 1.635 inches in length and 0.200 ¨
