[0059] Described herein are embodiments of safety razors, as well as lubrication devices and systems for safety razors, comprising at least one lubrication member. These lubrication members can be used to lubricate a user's skin while shaving and to reduce friction and skin irritation caused by a blade during shaving.
[0060] In some embodiments, a safety razor can comprise one lubrication member. In some of those embodiments, the lubrication member can be disposed above the blade. In other such embodiments, the lubrication member can be disposed below the blade.
[0061] In other embodiments, a safety razor can comprise more than one lubrication member. For example, in some of those embodiments, a safety razor can comprise a first lubrication member disposed above the blade and a second lubrication member disposed below the blade. In other such embodiments, a safety razor can comprise more than two lubrication members (e.g., three, four, five, six, etc.).
[0062] It should be noted that although illustrated embodiments are directed toward double-edge (DE) safety razors (i.e., safety razors with double-edge blades), single-edge (SE) safety razors (i.e., safety razors with single-edge blades) can be used.
[0063]
[0064] Referring to
[0065] Referring still to
[0066] In other embodiments, the lubrication member 116 can be disposed below the blade member 112, and the spacer member 114 can be disposed above the lubrication member 114 and below the blade member 112. In such embodiments, the guard member 110 can be laterally larger than the blade member 112, the spacer member 114, the lubrication member 116, and the cap member 114. The lubrication member 116 can be laterally larger than the spacer member 114, the blade member 112, and the cap member 114. The blade member 112 can be laterally larger than the spacer member 114 and the cap member 114. The cap member 118 can be laterally larger than the spacer member 114.
[0067] Referring to
[0068] The lubrication member 116 can be formed of various materials, including polymers, metals, etc. In some embodiments, the lubrication member 116 can be relatively rigid such that the lubrication member 116 can maintain its shape when a user presses the lubrication member 116 against the user's skin. In yet other embodiments, the lubrication member 116 can be relatively flexible such that the lubrication member 116 can bend or flex when a user presses the lubrication member 116 against the user's skin.
[0069] The lubrication member 116 can comprise a lubricating substance 138 which can, for example, be attached to the first and second edge portions 132, 134 of the lubrication member 116, as best shown in
[0070] The lubricating substance 138 can be formed from various materials, such as polyethylene oxide. The lubricating substance 138 can be configured to lubricate the user's skin as the user moves the safety razor 100 along the user's skin, thereby reducing the resistance (e.g., drag) of the safety razor 100 on the user's skin. This in turn can advantageously reduce skin irritation caused by the cutting edge portion 136 of the blade member pressing against and moving along the user's skin. Additional information regarding lubricants that can be used as lubricating substance 138 can be found, for example, in U.S. Pat. Nos. 5,454,164, 4,872,263, and 4,170,821, which are incorporated herein by reference.
[0071] The spacer member 114 can be formed of various materials, including polymers, metals, etc. In some embodiments, the spacer member 114 and the lubrication member 116 can be integrally formed as a single, unitary piece. In other embodiments, the spacer member 114 and the lubrication member can be formed as separate pieces which are fixedly secured together (e.g., with an adhesive, fasteners, etc.). In other embodiments, the spacer member 114 and the lubrication member 116 can be formed as separate piece that are removably coupled together (e.g., with the cap member 118 as further described below).
[0072] The components of the head portion 102 can include mating features configured to align and to prevent relative movement of the components of the head portion 102 when the head portion 102 is removably coupled to the handle portion 104. For example, referring again to
[0073] The projection 124 of the cap member 118 can also be used to removably couple the head portion 102 to the handle portion 104. For example, as shown in
[0074] In other embodiments, the head portion 102 can be removably coupled to the handle portion 104 in various other ways, including a snap-fit type connection, fasteners (e.g., bolts or screws), etc.
[0075]
[0076] Referring to
[0077] Referring still to
[0078] In other embodiments, the first lubrication member 210 and/or the second lubrication member 218 can be disposed above the guard member 212 and below the blade member 214. In such embodiments, the guard member 212 can be laterally larger than the first and/or second lubrication member 210, 218, the blade member 214, the spacer member 216, and the cap member 220. The first and/or second lubrication members 210, 218 can be laterally larger than the blade member 214, the spacer member 216, and the cap member 220. The blade member 214 can be laterally larger than the spacer member 216, and the cap member 220. The cap member 220 can be laterally larger than the spacer member 216. In some embodiments, one or more additional spacer members (e.g., similar to spacer member 216) can be disposed between the first and/or second lubrication members 210, 218 and/or the blade member 214.
[0079] Although not shown, in other embodiments, the safety razor 200 can comprise more than two lubrication members. For example, the safety razor 200 can include a third lubrication member. In one particular embodiment, the third lubrication member can, for example, be disposed between the guard member 212 and the blade member 214. The third lubrication member can be spaced relative to the blade member 214 by a spacer member (e.g., similar to spacer member 216).
[0080] Additionally or alternatively, the safety razor 200 can include one or more additional lubrication members adjacent to any and/or all of the lubrications members. For example, two additional lubrications can be disposed adjacent the second lubrication member 218 to form a stack or series of three lubrication members. In some of such embodiments, each lubrication member in the stack can abut an adjacent lubrication member. In other such embodiments, each lubrication member can be spaced relative to an adjacent lubrication member by a spacer member (e.g., similar to spacer member 216).
[0081] In some embodiments, the lubrication members can be tapered in the lateral direction relative to each other. In other words, each lubrication member can be at least slightly laterally larger than the lubrication members disposed above it and at least slightly smaller than the lubrication members disposed below it. The angle or amount of taper of the lubrication members can vary. In some embodiments, the angle of taper of the lubrication members can, for example, follow (at least generally) the taper of the other components of the head portion 202. In some embodiments, the angle of taper can be from about 0 degrees to about 60 degrees relative to the longitudinal axis of the handle portion. In particular embodiments, the angle of taper can be from about 20 degrees to about 40 degrees. In one particular embodiment, the angle of taper can be about 30 degrees. Tapering the lubrication members in this manner can, for example, allow each lubrication member to contact the user's skin when the safety razor 200 is angled against the user's skin during shaving.
[0082] Referring to
[0083] The second lubrication member 218 can have first and second edge portions 232, 234. The first and second edge portions 232, 234 can be parallel, or at least substantially parallel, to cutting edge portions 230 of the blade member 214 such that the first and second edges 232, 234 can contact a user's skin when a cutting edge portion 230 of the blade member 214 contacts the user's skin. The first and second edge portions 232, 234 can comprised various configurations (e.g., flat, rounded, angled, etc.). As shown, in one particular embodiment, the first and second edge portions 232, 234 can be rounded.
[0084] The first and second lubrication members 210, 218 can be formed of various materials, including polymers, metals, etc. The first and second lubrication members 210, 218 can comprise a lubricating substance 238 which can, for example, be attached and/or applied to the first and second edge portions 226, 228, 232, 234 of the first and second lubrication members 210, 218, as best shown in
[0085] The lubricating substance can also be attached or applied to various other portions of the first and second lubrication members 210, 218. For example, as shown in
[0086] The lubricating substance 238 can be formed from various materials, such as polyethylene oxide. The lubricating substance 238 can be configured to lubricate the user's skin as the user moves the safety razor 100 along the user's skin, thereby reducing the resistance (e.g., drag) of the safety razor 200 on the user's skin. This in turn can advantageously reduce skin irritation caused by the cutting edge portion 136 of the blade member pressing against and moving along the user's skin.
[0087] The components of the head portion 202 can include mating features configured to align and to prevent relative movement of the components when the head portion 202 is coupled to the handle portion 202, for example, in a manner similar to the safety razor 100. The head portion 202 and the handle portion 204 can be removably coupled together, for example, in a manner similar to the safety razor 100.
[0088]
[0089] Referring to
[0090] Referring still to
[0091] As shown in
[0092] Referring still to
[0093] The lubrication strips 328 can be coupled to the first lubrication member 308 in various ways such as with adhesive, fasteners, and/or molding or injecting the strips on the first lubrication member 308. In some embodiments, the lubrication strips 328 can include a lubricating substance or coating that is applied and/or formed on the first lubrication member 308.
[0094] As shown in
[0095] As also shown in
[0096] The blade 310 can be configured similar to the blade 112 of the safety razor 100.
[0097] Referring again to
[0098] The second lubrication member 314 can comprise lubrication strips 334. For example, in the illustrated embodiment, the lubrication member 314 has two lubrication strips 334 (i.e., one on each side of the second lubrication member 314) extending therefrom. The lubrication strips 334 can be disposed in the notches 332 of the guard 312.
[0099] In some embodiments, the guard 312 can extend laterally beyond lubrication strips 334 adjacent the notches 332 of the guard 312, as shown in
[0100] The lubrication strips 334 can contact and lubricate a user's skin as the user slides the head portion 302 of the safety razor along their skin.
[0101] In other embodiments, the second lubrication member 314 can have more or less than two lubrication strips 334 (e.g., 1-20). In some such embodiments, the guard 312 can have one or more openings (e.g., similar to the openings 324 of the cap 306) rather than the notches 332. The second lubrication member 314 can extend through the openings of the guard 312 similar to the manner in which the lubrication strips 328 extend through the openings 324 from the cap 306.
[0102] The lubrication strips 334 can be coupled to the second lubrication member 314 in various ways such as with adhesive, fasteners, and/or molding or injecting the strips on the second lubrication member 314. In certain embodiments, the second lubrication member 314 can include ridges (e.g., similar to the ridges 330 of the first lubrication member).
[0103] In some embodiments, the lubrication strips 334 can include a lubricating substance or coating that is applied and/or formed on the second lubrication member 314.
[0104] In lieu of the second lubrication member 314, the safety razor 300 can include a skin tensioning member. The skin tensioning member can be configured to stretch the user's skin and prepare the hair to be cut as the user slides the head portion 302 of the safety razor along their skin. In certain embodiments, the skin tensioning member can be comprise a polymer and/or a polymeric coating. In some embodiments, the skin tensioning member can, for example, include ribs, nubs, and/or other projections.
[0105] A user can use the safety razor 300 with or without the first lubrication member 308 and/or the second lubrication member 314 or the skin tensioning member installed on the head portion 302 of the safety razor 300. One particular advantage of the safety razor 300, for example, is that the portion of the blade 310 that is exposed beyond the cap 306 and/or the guard 312 is the same with or without first lubrication member 308 and/or the second lubrication member 314 or the skin tensioning member installed on the head portion 302 of the safety razor 300. This is illustrated in
[0106] When using the safety razor 300 without the first lubrication member 308, the openings 324 in the cap 306 can, for example, provide additional channels through which fluid (e.g., water) can flow to improve rinsing and cleaning of head portion 302. This can, for example, also reduce or prevent cut hair from clogging the blade 310.
[0107] In some embodiments, various components of the safety razors 100, 200, 300 (e.g., lubrications members 116, 210, 218, 308, 314, spacers 114, 216, caps 118, 220, 306, etc.) can be a separate lubrication device and/or system that can be configured to be used with various other safety razors. For example, the lubrication member 116, the spacer 114, and the cap 118 can be a lubrication system configured to be removably coupled to a safety razor that does not have a lubrication system and/or that has an additional or alternative lubrication system. In another example, the cap 306 and the first lubrication member 308 can be a lubrication system configured to be coupled to a safety razor that does not have a lubrication system and/or that has an additional or alternative lubrication system. This advantageously allows a user to selectively interchange and/or exchange each component as desired.
[0108] Configuring a safety razor (e.g., safety razors 100, 200, 300) and/or a lubrication system as described herein can advantageously allow a user to independently remove and/or replace each component of the head portion (e.g., the head portion 102) and/or the handle portion (e.g., the handle portion 104) of the safety razor as desired. For example, a user can exchange a dull blade member for a new blade member and can continue to use the lubrication member if there is an unused portion of the lubricating substance on the lubrication member. As another example, a user can exchange the lubrication member for a new lubrication member and can continue to use the blade member if the blade member is still sufficiently sharp. The safety razors and lubrication systems described herein are therefore relatively more economical and less wasteful than typical cartridge razors which require a user to exchange the entire head portion when only a single component (e.g., the blade member) needs to be replaced.
[0109] In addition, the safety razors and lubrication systems described herein can also significantly improve typical safety razors by providing lubrication members and lubricating substances for a safety razor which can, for example, advantageously improve the closeness and/or comfort of a shave compared to typical safety razors.
[0110] In view of the many possible embodiments to which the principles of the present disclosure may be applied, it should be recognized that the illustrated embodiments are only preferred examples and should not be taken as limiting the scope of the disclosure. Rather, the scope of the present disclosure is defined by the following claims. I therefore claim all that comes within the scope and spirit of these claims.
