Description

  The present disclosure relates to a shaving apparatus having a lubricated shaving aid for facilitating the razor being pulled along the skin during the shaving process. In particular, the present disclosure relates to a shaving system that utilizes a thermoelectric device to selectively release shaving aid as needed.

  Many factors are known that contribute to the overall discomfort during the shaving process. Such factors may include excessive rub resistance of the razor along the skin and inflammation of various known epidermal conditions that can be stimulated by the shaving process, such as psoriasis, eczema, erythema, rash, acne and the like. As a result of efforts directed at some of these factors, preservatives such as pre-shave and / or after-shave lotions, beard softeners, soap foam softeners, pharmaceutical or softening ointments, aloe, foams, soaps etc. are used It has become so. Even though the comfort of shaving is improved to some extent using one or more of the above-mentioned relaxation agents, the need for them to be applied before or after shaving tends to reduce their overall effectiveness, In addition, a complex and time-consuming shaving process is simply added.

  It is also known that the shaving device itself can be significantly improved by utilizing a shaving aid that lubricates the skin engaging the surface during the shaving process. For example, static lubricated shaving aids are known that are attached integrally or separately to a shaving device, typically close to the blade, so that when the shaving device is pulled along the skin of the person to shave, the element The frictional resistance of the skin that engages is substantially reduced. Typically, these shaving aids are manufactured as a lubricating strip, which is attached to a razor head proximate the razor cap. Lubricating strips usually contain water-insoluble polymeric materials such as polystyrene and water-soluble shaving aid modifiers such as polyethylene oxide, which tend to leach out of the strip during shaving and reduce shaving due to reduced friction. Improve comfort. Unfortunately, conventional shaving aid strips tend to release an unbalanced amount of shaving aid during the period. Initially a large amount of leaching from the strip, but after repeated use, gradually decreasing amounts are released. Furthermore, after repeated use, the surface of the strip may become irregular and rough, thereby increasing the coefficient of friction of the strip that contributes to further skin irritation.

  As a result, some manufacturers have attempted to develop new devices for the delivery of shaving aids to improve and extend the shaving aid release during the initial shaving process and over multiple shaving processes. Other efforts are directed to providing a feeding device that stably applies an appropriate amount of shaving aid over repeated shavings. In general, however, many of these efforts are partly in the ability to stably supply shaving aids over repeated shaving cycles and maintain a stable and acceptable level of comfort during the shaving process. It is only successful.

  Referring now to FIGS. 1-3A, there is shown one embodiment of a shaving aid delivery apparatus that is used before and / or during the shaving process and indicated generally by reference numeral 60. The shaving aid delivery device 60 can be incorporated into various known types of disposable razors. In such disposable razors, the razor (or usable portion thereof, such as a razor head cartridge) is removed and replaced after a selected number of shavings.

  The embodiment of the present disclosure depicted in FIGS. 1 and 2A shows a shaving device 10 in the form of a razor head cartridge 12. The razor head cartridge 12 includes a support base 14 having elastic supports 50 and 55, and the elastic supports 50 and 55 movably connect a pair of sharp blades 20 a and 20 b and a cap member 30 to the support base 14. To do. 1 and 2 illustrate a shaving device 10 with a disposable cartridge 12, the advantages of the present disclosure are equally applicable to other razor designs and shaving devices, such as the shaving device 10 '(see FIG. 2B). is there. The term “razor head” as used herein is similar to a disposable razor in which skin engaging portions (ie, guard bars, blades, caps, and lubricated shaving strips) are integrally formed with the razor handle portion 100. , Meant to include a cartridge 12 designed and manufactured for attachment to a separate razor handle 100. In addition, although the shaving device disclosed herein generally relates to facial shaving devices, the shaving aid delivery device disclosed herein is concerned with other skin areas such as legs, arms, surgical areas, and the like. It can be included in other known shaving devices that match.

  The razor heads 12, 12 'depicted in FIGS. 1, 2A and 2B include a support base 14, which is defined by a front surface 17 and a rear surface 19, respectively, and is defined by fixed side walls 15a, 15b. . The guard member 40 that engages with the skin is attached to the support base 14 and is attached along the vicinity of the front surface 17 of the base 14. The shaving strip is disposed along the rear surface 19 of the base 14. As best shown in FIGS. 2A and 2B, the seat blade 20a and the cap blade 20b are supported by a plurality of elastic support members 50,55. The tips of the blades 20a and 20b include cutting edges 21a and 21b, respectively. These cutting edges 21a and 21b are in the range of about 1 mm from the forefront of the blades 20a and 20b.

  Preferably, the cutting edges 21a, 21b of the razor blade are coated with a thin layer of a metal coating, for example made of chromium or a chromium platinum alloy, thereby providing improved durability and corrosion resistance to the underlying metal. Other materials may be coated on the razor blades 20a, 20b. For example, various coating materials disclosed in US Pat. No. 5,630,275 can be coated, the entire contents of which are incorporated herein by reference.

  The support members 50 and 55 are attached along the base 14 and support the blades 20a and 20b. The guard member 40, blades 20a, 20b, cap member 30, lubricating strip 64, and outer surfaces of the side walls 15a, 15b together define the face 16 of the razor head 12 (12 '). These elements are hereinafter commonly referred to as “skin engaging elements”.

  Preferably, a plurality of elastic supports 50, 55 are disposed at various locations along the face 16 of the razor head 12 (12 ′) to increase the stability of the blades 20a, 20b and provide greater flexibility. provide. The support members 50 and 55 are designed to have sufficient inherent elasticity and are directed downward with respect to the side walls 15a and 15b depending on normal forces that the blades 20a and 20b and the cap member 30 receive during shaving. That is, it is allowed to move toward the base 14. Preferably, the elastic support members 50 and 55 are manufactured from the same elastic material. However, the elastic support members 50, 55 can also be manufactured from different elastic materials having different elasticity. The length and position of the elastic support members 50, 55 can also be modified to increase or decrease the overall aggressiveness of the shaving geometry depending on the force experienced during shaving. For example, if the length of one elastic support (eg 55) is shorter than the other elastic support (eg 50), the overall shaving angle that directly correlates to the aggressiveness of the shaving depends on the vertical shaving force It will change.

  The guard member 40 has a rear surface 42 for securing it to the base 14 and an outermost guard surface 41. The guard surface 41 is preferably made from an elastic, skin-engaging material that has a higher coefficient of friction with wet skin than hard plastics of the type commonly used with many disposable cartridges 12. Preferably, the guard surface 41 is designed to limit the extent to which the razor is pressed against the skin, thereby protecting it from skin cuts and scratches.

  Guard member 40 may be a single part or multiple parts as described in commonly owned US Pat. Nos. 5,689,883 and 5,475,923.

As can be appreciated, the higher the coefficient of friction of the elastic material, the more the guard member 40 (and the side walls 15a, 15b) can be gripped by the skin, making the skin more noticeable when the skin passes over the blades 20a, 20b. Can be controlled. In addition, the elastic material provides the skin with a more detectable sensation in a way that would tend to hide the discomfort of a sharp blade moving along the skin.

  The cap member 30 is seated on the top blade 20b. Depending on the particular purpose, the cap member 30 may be formed as a single piece extending in the width direction of the face 16 of the razor head 12, 12 ', or the cap member may comprise a plurality of individual segments. Can be divided into In order to unify the overall movement of the blades 20a, 20b and cap member 30 along the skin during the shaving stroke, the cap member 30 is either integrated into one or more elastic supports 50, 55 or attached separately. May be. Other advantages relating to the construction of the cap member 30 are set forth in commonly owned US Pat. Nos. 5,822,862, 5,666,729, and 5,456,009, the entire contents of all of which are hereby incorporated by reference.

  As best shown in FIGS. 2A and 2B, the shaving device 10 (10 ′) includes a shaving aid supply device 60 in accordance with the present disclosure, which is disposed on the razor head 12 (12 ′). The shaving aid 300 is selectively supplied before and / or during the shaving process. In particular, the shaving aid supply device 60 includes a container or container 62 that stores a predetermined amount of shaving aid 300 for dispersion, and a lubricating strip 64 that is disposed on top of the container 62 and engages the skin during the shaving stroke. Preferably, a base or shelf 61 supports the container 62 within the razor head 12 (12 '). However, other means for supporting the container 62 (eg, brackets, pins, tabs, etc.) are also conceivable.

  Generally, the container 62 includes a heating device (eg, resistor 65) disposed therein. The heating device is electrically connected to a power source 135 (for example, a battery) via an actuator or switch 130. For purposes herein, the term “heating device” includes a heating element 65 and a power source (eg, battery 135). Preferably, a switch 130 is placed on the razor handle 100 to allow the user to easily and selectively dispense the shaving aid 300 from the container 62 as required before and / or during the shaving process. To. Container 62 further includes a discharger or nozzle 68. The ejector or nozzle 68 discharges the shaving aid 300 from the container 62 to the lubricated shaving strip or pad 64 as will be described in more detail below in connection with FIGS. 3A-3C. Preferably, the nozzle 68 is tapered to facilitate dispensing the shaving aid 300 in droplets on the top of the shaving strip 64. Alternatively, the nozzle 68 may be dimensioned to discharge the shaving aid in a spray form. The shaving strip 64 is positioned near the rear surface 19 of the razor head 10 (10 ') and is oriented to engage the skin surface during a normal shaving stroke. The shaving strip 64 may be formed in a single structure (see FIG. 3B) or may be divided into segments. (See FIG. 1, FIG. 3A, FIG. 3C).

  The shaving device can be designed such that the shaving aid 300 is automatically distributed before and during the engagement of the razor 12 with the skin. For example, the actuator or switch 130 can be automatically activated (ON) upon contact with the face and / or temperature change (hot water).

  FIG. 2A shows one embodiment of a dispensing device 60 that is used with a disposable razor head 12 (ie, commonly referred to as a “razor cartridge”) that selectively engages a permanent razor handle 100. Designed to be. The razor head 12 may engage the razor handle 100 using various engagement mechanisms or techniques known in the art. Such mechanisms or techniques are described, for example, with respect to commonly owned U.S. Pat. The entire contents of all these US patents are discussed and incorporated herein by reference.

  With particular reference to the embodiment shown in FIG. 2A, the handle 100 (or at least a portion thereof) is dimensioned to engage a corresponding hole 23 located in the razor head 12. The razor head 12 includes a notch 27 disposed therein, the notch 27 being dimensioned to selectively engage a pin 112 protruding from the razor handle 100. Preferably, the connection between the pin 112 and the notch 27 allows the razor head 12 to rotate in response to the normal force experienced during shaving.

  An electrical contact 25 is also disposed on the razor head 12. The electrical contacts 25 are designed to electrically connect with corresponding contacts 120 located on the handle upon engagement of the razor head 12 with the top of the handle 100. An electrical cable 67 (or the like) can be used to connect the contacts 25 to the heating element 65. Similarly, additional cables 137 and 139 can be used to electrically connect the contacts 120 to the power source 135 via the switch 130.

  As can be appreciated, the contacts 25, 120 (and electrical cables 139, 137, 67) provide electrical continuity from the power source 135 to the heating element 65 when the switch 130 is turned on.

  When the switch 130 is turned on, the heating element 65 is immediately heated, thereby transferring a significant amount of energy to the shaving aid 300. As a result, a small portion of the shaving aid is immediately evaporated and a bubble 400 is generated in the container 62. As the bubble expands, a pressure wave “A” (s) is generated which pushes the shaving aid foes from the nozzle 68 onto the shaving strip 64. By controlling the energy transfer to the shaving aid 300, the bubble 400 immediately collapses before any shaving aid vapor exits the nozzle 68. A control circuit (not shown) may be included in switch 130 to control the overall supply of shaving aid in operation.

  As can be appreciated with this particular embodiment, if the shaving aid 300 is depleted after a certain number of shavings, the user simply replaces the razor head 12 with a new razor head that includes a container filled with the shaving aid 300. To do. Alternatively, the shaving device 60 may be designed such that the user selectively replaces and / or refills one or more containers 62 at any time regardless of the wear of the razor head 12. As will be described below, the container 62 may include an independent orifice or inlet (not shown), which allows the user to identify a new shaving aid 300 as required during the life of the razor head 12. Can be injected into a container.

  FIG. 2B shows another embodiment of the supply device 60 located in the shaving device 10 ', where the entire shaving device 10' is disposable. This embodiment has many features similar to the shaving device 10 except that the razor head 12 ′ is integral with the razor handle 100. Similar shaving devices are described in US Pat. Nos. 5,678,316 and 5,575,068, the entire contents of these US patents are hereby incorporated by reference.

  As best shown in FIGS. 3A-3C, a plurality of containers may be included in the shaving aid delivery device 60 so that the user can selectively select different shaving aids 300 from a particular container on demand. Can be supplied. In particular, the shaving device 60 may include a series of containers 62a, 62b, 62c that discharge the shaving aid 300 on demand to provide a common heating element 65 (see FIG. 3A) or a plurality of individual Heating elements 65a, 65b, 65c (see FIG. 3B) may be included. As can be appreciated, each heating element (eg, 65a) can be individually connected to a switch (eg, 130a) to provide the desired amount of shaving aid 300a when actuated by the user.

  The delivery device 60 may be a single or series of interconnected micro-ducts or micro-channels (not shown) (or other types of microfluidics technology). This mixes the various shaving aids 300 from the containers 62a, 62b, 62c before and / or after discharge from the nozzles 68a, 68b1, 68b2, 68c. As can be appreciated, mixing shaving aids in this manner provides a more homogeneous shaving aid solution for shaving and comfort purposes.

  In one embodiment, switch 130 includes a circuit (not shown) that adjusts the appropriate amount of shaving aid 300 dispensed from a particular container 62a-62c based on individual user requirements. For example, the user can select a specific switch setting labeled “sensitive”, which dispenses from the container 62 a shaving aid 300 having a sensitive shaving emollient. Alternatively, a specific amount of shaving aids 300a, 300b, 300c from a plurality of containers 62a-62c is mixed and the shaving aids 300a-300c are distributed on the shaving strips 64a-64c to add to sensitive skin Protection is given. Another user can select another setting, such as “heavy beard”, which results in a different shave feeling or a different combination or amount of containers 62a-62c. A shaving aid 300 is issued.

  FIG. 3B shows another embodiment of the shaving aid supply apparatus 60. In this, each individual container (eg, container 62a) includes a separate heating element (eg, 65a) electrically connected to an individual switch (eg, switch 130a). Selectively adjust the amount of shaving aid 300 dispensed from the container 62a, as described above, the switch (eg, switch 130a) adjusts the expansion of the bubble (eg, 400a) to reduce evaporation of the shaving aid 300a. Further, the supply device 60 may include a plurality of nozzles (for example, 68b1 and 68b2) disposed in the respective containers (for example, the container 62b) (see FIGS. 3B and 3B). 3C), so that the shaving aid 30 through the shaving strip 64 Homogeneous distribution of b is accelerated.

  FIG. 3C shows yet another embodiment of the shaving aid supply device 60 in which each container 62a, 62b, 62c faces the face 16 of the razor head 12 (eg, blade members 20a, 20b and cap member 30). The dimension extends across the row (in parallel). In particular, the container 62a is disposed close to the cap member 30, the container 62b is overlaid after the container 62a, and the container 62c is overlaid after the container 62b. As can be appreciated, forming containers 62a-62c in this manner facilitates the individual shaving aids 300a-300c being evenly distributed across the shaving surface during the shaving stroke in the direction of arrow "B". To do. A series of nozzles 68a, 68b, 68c may be disposed along each shaving strip 64a, 64b, 64c, respectively, thereby providing a uniform distribution of shaving aids 300a, 300b, 300c across each shaving strip. It becomes easy.

  The present disclosure further relates to a method of releasing the shaving aid 300 from the razor head 12 and includes the following steps: a container 62 for holding the shaving aid 300, a heating element disposed in the container and in contact with the shaving aid 300 65, a razor having a shaving strip 64 disposed on the razor head 12 and oriented to engage the user's skin during the shaving stroke, and a discharge port (eg, nozzle 68) that directs the shaving aid 300 from the container 62 toward the shaving strip 64. Providing a head 12; The method further includes the following steps: selectively actuating the heating element 65 to cause rapid volume expansion of the shaving aid 300 such that the shaving aid 300 is distributed from the discharge port 68 to the shaving strip 64.

  From the foregoing description and with reference to the various drawings, those skilled in the art will recognize that certain modifications may be made to the disclosure without departing from the scope of the disclosure. For example, although two blades 20a, 20b are used for illustrative purposes, the razor head may include one, two, or more than two blades. The cap member 30 may be divided into a large number of segments in order to remove strain at the time of shrinkage after molding. At least one of the blades 20a, 20b may include one or more fencing elements. Such surrounding elements are described, for example, in U.S. Pat. Nos. 3,263,330, 3,507,734, 3,750,285, and 4,12,2006, the entire contents of all of which are incorporated herein by reference.

  Further, two users may purchase the same shaving device 10 and then select different combinations of shaving aids 300 from any number of containers 62. This provides a personalized shaving experience based on individual requirements (eg, a soothing agent for sensitive skin and / or a softening agent to soften a lot of beards). The shaving aid supply device 60 may be disposed on another skin engaging surface (for example, the guard bar 40, the cap member 30, and / or the side walls 15a and 15b) of the razor head 12. Alternatively, the shaving aid supply device may be used without a comfort strip. That is, the shaving aid 300 is released directly from the container (s) 62 onto the user's skin (eg, “sprayed” onto the skin) during operation.

  Further, the user can selectively distribute different shaving aids 300 during the shaving process. For example, a user can initially dispense a specific shaving agent 300a from a specific container 62a and / or a set of containers 62a, 62b, 62c to soften the user's beard prior to shaving. (In this example, for example, the user simply applies the pre-shave softener to the skin without cutting, so the shaving stroke is reversed (i.e., contrary to the expected cutting stroke direction “B” of the blades 20a, 20b). )can do). The user then applies secondary shaving aids 300b, 300c (or combinations thereof) (eg, sensitive shaving aids, aftershaves, etc.) as required during the shaving process to obtain the desired shaving feeling. be able to.

  Further, the one or more containers may include a second port or hole so that the container (s) can be replenished with one or more shaving aids. For example, razors can be sold with a syringe. The syringe engages the second hole and allows the user to refill the container with the required additional shaving aid (s).

  Further, the shaving apparatus disclosed herein can use microfluidic techniques for mixing and / or evenly distributing shaving aids to comfort strips. In addition, the shaving strip can be made from a porous or permeable membrane having a unidirectional flow, which absorbs the shaving aid for engagement and release to the user's skin during subsequent shaving. To do.
