Description

Application area

The present invention relates to shaving methods and hair shaving kits. In particular, the present invention relates to shaving kits, including trays for storing the shaving device and holding the shaving aid, shaving devices having protective elements for holding and applying the shaving aid to the skin, and methods for using such shaving devices and kits.

State of the art

Typically, men and women shave their bodies by first applying a layer of shaving aid, such as a gel, cream, soap, or lotion, with their hands on the area to be shaved. The user then shaves his skin with a wet shaver. The wet shaver is periodically rinsed with water to remove cut hair that lingers in it. This shaving method requires the user to purchase a jar or tube with a shaving aid and wet shaving device, which can be disposable or a shaving kit that uses interchangeable cartridges. The shaving tube or jar contains shaving aid in an amount sufficient for a plurality of shaving sessions and exceeds the service life of several disposable wet shaving razors and / or disposable cartridges in typical use.

The aforementioned shaving method has several disadvantages. First, it requires the consumer to purchase and apply shaving aids to the skin in an amount greater than necessary. For example, some consumers need to shave while traveling, on a business trip, or on vacation. Currently, airports strictly control the presence of sharp objects, such as razor blades, in the passenger, and the amount of liquid hygiene products transported is limited, which creates inconvenience for travelers regularly or occasionally. Some travelers find it easier to buy new shaving products and shavers after arriving at their destination than to have trouble taking these items on board. Although relatively inexpensive disposable razors are available today, a consumer should also buy a can or tube of shaving aid, which can be relatively expensive, given that a shaving aid is only needed for a few shaving sessions. It turns out that the jar or tube with the shaving aid contains a deliberately excessive amount of shaving aid, which is usually thrown away by the traveler along with a disposable razor before returning home. If the user prefers to carry with him a supply of shaving products, the container (s) for shaving products creates additional weight and volume of luggage. The average traveler does not need the full capacity of the lotion if he is not going to stay outside the house for an extended period of time.

Before shaving, the shaving aid is usually applied in excess to the hand and spreads over the skin. During this process, you can get dirty, this leads to the use of excess shaving aid, and the consumer will need to wash their hands before taking their shaving device. Thus, with every shave, an extra amount of shaving aid is consumed, which is not very economical. Rinsing the shaver is also a problem if there is no running water or if they are trying to save water. For example, running water may not be available to consumers on a camping trip or camping, in the wild, away from modern amenities. In certain regions of the planet, such as developing countries, water shortages may also occur. In addition, water problems can occur in other situations. For example, consumers who are constantly in a hurry often have to shave in unusual places, such as in a car or in public transport. The process of applying shaving aid is also inconvenient for users who are in a hurry and shave on the go. For these reasons, some consumers prefer to use an electric razor or put off shaving for later, even if ideally they prefer to have the look and feel that only a thorough shave with a wet shave gives.

SUMMARY OF THE INVENTION

In some embodiments, the cartridge 16 may be mounted on the handle 14 with the possibility of removal and / or rotation. If necessary, the cartridge 16 can be removed from the handle 14 by the user and replaced with a new cartridge 16, and the handle 14 is then reused. In other embodiments, the cartridge 16 can be permanently mounted on the handle 14, and the consumer, when he feels the need, can discard the wet shaving device 12 and replace it with a new wet shaving device 12. As will be described in detail below, the cartridge 16 may include a protective element 18 that holds the shaving aid and is designed to apply the shaving aid to the skin surface during shaving. The shaving kit 10 may include a shaving tray 20 for receiving the wet shaving device 12 and a disposable container 22 with shaving aid.

The shaving tray 20 may have a proximal portion 24 and a distal portion 26. The distal portion 24 may have a container 28 that is sized to fit a disposable container 22 with shaving aid. Alternatively, the container 28 may itself be filled with shaving aid. The wet shaving device storage part 30 may be located between the proximal part 24 and the distal part 26. The wet shaving device storage part 30 may have a recessed area 32 and a handle holding member 34, as well as a generally open area 36. The area 32 with a recess may have a size suitable for placing the cartridge 16 therein, and in general, the open area 36 may be suitable for accommodating the handle 14 of the wet shaving apparatus 12 thereon. The recessed region 32 may have a drainage hole 38 extending across the razor tray 20, which may assist in drying the cartridge 16 after shaving as soon as possible. The handle holding member 34 may fix the handle 14 in the shaving tray 20 and may be located between the recess area 32 and the generally open area 36. The shaving tray 20, the shaving device 12, and the shaving aid container 22 may Be packed together as a kit. The shaving container 22 can be sold separately and can be replaced if necessary. The shaving device 12 may be disposable, that is, disposed of along with the tray 20 and the container 22 with shaving aid after a certain number of shaving sessions. In some embodiments, the razor 12 and the container 22 with the shaving aid may be packaged as a set without a tray 20 for the razor.

FIG. 2 shows a wet shaving device 12 immersed in a container 22 with shaving aid that can be placed in a container 28 of a tray for a shaving device 20 (not shown). The wet shaving device 12 may have one or more razor blades 42 located between the cover 44 located at the rear of the cartridge 16 and the protective element 18 holding the shaving aid and located at the front of the cartridge 16. In some embodiments, the protective element 18 shaving aid holding means may be used in place of cap 44, i.e., cartridge 16 may include a plurality of shaving aid holding elements 18, or may have protective the th element 18 holding the shaving aid located in place of the lid 44. The container 22 with the shaving aid may have a lid 40. The lid 40 may be a tear-off lid, i.e. be removed from the container 22 with the shaving aid, or the lid 40 may be adapted to be put on the container 22 with the shaving aid (for example, with a snap). The shaving aid container 22 may be sized to immerse the cartridge 16 of the wet shaving apparatus 12 therein. The shaving aid container 22 may be slightly larger than the cartridge 16 and may contain a sufficient amount of shaving aid for about one to two to about four to five shaving sessions. The shaving aid container 22 may generally have a rectangular shape, and its length generally corresponds to the length of the cartridge 16. In some embodiments, the length of the shaving aid container may be from about 25 mm, 35 mm, or 45 mm to about 55 mm, 65 mm or 75 mm. The shaving aid container 22 may have a height that matches the width of the cartridge 16, which can prevent excess shaving aid from falling onto the handle 14. In some embodiments, the height of the shaving aid container may be from about 10 mm, 12 mm, or 14 mm to about 20 mm, 30 mm or 40 mm. The shaving aid container 22 may also have a width that generally corresponds to the width of the cartridge 16, as described above.

When the user immerses the cartridge 16 in the container 22 with the shaving aid, the protective element 18, designed to hold the shaving aid, captures a certain amount of shaving aid and holds it. Then, the cartridge 16 can be brought to the area of the skin to be shaved. While the cartridge 16 extends along the skin surface, the shaving aid holding member 18 can apply the shaving aid in front of one or more razor blades 42 that shave the skin surface. The shaving aid can thus be applied to the skin at the same time as the skin is shaved with one or more razor blades 42. Alternatively, the user can bring only the protective element 18 holding the shaving aid to the area of the skin to be shaved. Using the shaving aid holding member 18, it is possible to apply the shaving aid to the entire surface area of the skin to be shaved before bringing the razor blades 42 into contact with the skin. The user can then attach one or more razor blades 42 contained in the cartridge 16 to the skin and shave this skin area. As necessary, the user can periodically rinse the cartridge 16. Hair stuck in the cartridge 16 can also be washed off by loading the cartridge 16 back into the container with shaving aid. The shaving aid may be lower viscosity than conventional shaving lotions and gels, which may help to better rinse and clean one or more razor blades 42. In some embodiments, in the container 22 with the shaving aid (or in a separate tube or bag, as will be described in more detail below) may contain a Nivea Cool shaving balm (Philips Philishave HQ170 or HQ171) from Koninklijke Philips Electronics NV

The distal portion 54 may have a first container 56, which is sized to accommodate a disposable container 22 with shaving aid (not shown). The distal portion 54 may also have a second container 58, which can be used as a tank for rinsing the cartridge. The second container 58 may be filled with water or rinse aid. The wet shaver 12 (not shown) may be a vibrating razor, which may be useful to better rinse the cartridge 16 (not shown) in the second container 58. The wet shaving device storage part 60 may be located between the proximal portion 52 and the distal part 54. Part 60 for storing the wet shaver may have a region 62 with a recess, the handle holding member 64 and a generally open area 66. The region 62 with the recess may be suitable for holding the cartridge 16 (not shown), andin general, the open area 66 may be sized to accommodate the handle 14 of the wet shaver 12 (not shown). The recessed region 62 may have a drainage hole 68 extending across the razor tray 50, which may be useful for drying the cartridge 16 (not shown) after shaving. The handle holding member 64 may fix the handle 14 in the razor tray 50 and may be located between the recess area 62 and the generally open area 66.

The second container 58 may have a generally rectangular shape and a length generally corresponding to the length of the cartridge 16 (not shown). The second container 58 may be the same size as the container 22 with shaving aid (see FIG. 2), or larger. In various embodiments, the length of the second container 58 may be from about 35 mm, 45 mm or 55 mm to about 65 mm, 75 mm or 85 mm. The second container 58 may also have a height that usually corresponds to the width of the cartridge 16, which can prevent excess water or rinsing solution from entering the handle 14 (not shown). In some embodiments, the height of the rinse container 58 may be from about 10 mm, 12 mm, or 14 mm to about 20 mm, 30 mm, or 40 mm.

FIG. 3B is a top view of yet another possible embodiment of the shaving tray 150. The razor tray 150 may have a proximal portion 154 and a distal portion 156. A wet shaving device storage portion 160 is located between the proximal part 154 and the distal portion 156.

The tray 150 can be the same as the razor tray 20 described previously and shown in FIG. .one. The capacity 158 of the tray 150 for the razor can be located inside the part 160 for storing the razor, or within the generally open area 166. The location of the container 158 further from the far part 156 may allow the manufacture of the tray 150 of a shorter length, but with the possibility of holding the container 22 with shaving aid.

The shaving tray 150, the wet shaving device 12 and the container 22 with shaving aid can be packaged together as a set. The shaving aid container 22 may be purchased separately by the user as needed and replaced in a container 158 of the shaving device tray 150. The shaving device 12 may be disposable and may be discarded with a tray 150 and a container 22 with shaving aid after a certain number of shaving sessions. In some embodiments, the razor 12 and the container 22 with the shaving aid can be packaged as a kit without a tray 150 for the razor.

On figs shows a top view of another possible embodiment of the shaving tray 200 for the shaving device. Tray 200 may be the same as the razor tray 50 described above and shown in FIG. 3A.

The shaving tray 200 may have a proximal portion 202 and a distal portion 204. The wet shaving device storage portion 210 may have a first container 206 that is sized to fit a disposable container 22 with shaving aid (not shown).

The recessed area 212 may be suitable for receiving a cartridge 16 (not shown) in it, and the generally open area 216 may be suitable for placing a handle on it tissue 14 (not shown) of the wet shaver 12 (not shown). The recessed region 212 may have a drainage hole 218 extending across the razor tray 200, which may be useful for drying the cartridge 16 (not shown) as soon as possible after shaving. The handle holding member 214 may fix the handle 14 (not shown) in the shaving tray 200 and may be located between the recessed area 212 and the generally open area 216.

The second container 208 may have a generally rectangular shape, and its length generally corresponds to the length of the cartridge 16 (not shown). The container 208, which can be used as a rinse tank, can be the same size as the container 22 with shaving aid (see FIG. 1), or larger. In some embodiments, the length of the rinse tank 208 may be from about 35 mm, 45 mm or 55 mm to about 65 mm, 75 mm or 85 mm. The second container 208 may also have a height generally corresponding to the width of the cartridge 16, which may help prevent excess water or rinsing solution from entering the handle 14 (not shown). In some embodiments, the height of the second container 208 may be from about 10 mm, 12 mm, or 14 mm to about 20 mm, 30 mm, or 40 mm. Tray 200 may be the same as the razor tray 50 described above and shown in FIG. 3A, however, the container 206 and the rinse tank 208 may be located in the tray 200 inside the razor storage portion 210 or in the open area 216. The location of the rinse tank 206 and the rinse tank 208 further from the distal portion 204 may make it possible to produce a tray 200 of shorter length, but with the possibility of holding the container 22 with shaving aid therein.

3D and 3E show two more embodiments of the razor trays 250 and 300. The razor trays 250 and 300 may have containers 258 and 306 for the shaving aid 22, respectively, and / or a second container 308 located on the lower surface 252 and 302 of the tray 250 or 300, respectively.

The location of the containers 28, 306 and 308 on the lower surface of the tray 250 and 300 for the razor can reduce the overall length of the tray, that is, make the shaving kit more compact.

FIG. 4A shows an alternative embodiment of the shaving kit 70, which may include a wet shaving device 12 and a soft pack 72 with shaving aid, such as a tube. The shaving aid 74 may have a viscosity greater than the viscosity of the shaving aid in the container 22 with the shaving aid described above. The viscosity of the shaving aid 74 (or shaving aid in the container 22 with the shaving aid) may be about the same as the viscosity of the toothpaste or gel, such that the shaving aid holding member 18 can be applied a portion (in the form of a strip) of the shaving aid 74, and this strip could be held by the security element 18. In some embodiments, the shaving aid 74 may have a viscosity of from about 2,000, 10,000 sludge 25,000 cps to about 50,000, 75,000 or 250,000 cps at room temperature (about 23 ° C). In other embodiments, the shaving aid 74 may have a viscosity of from about 10, 50, or 100 cPs to about 150, 250, or 500 cPs at room temperature (about 23 ° C).

The user can squeeze the shaving aid 74 from the soft pack 72 onto the shaving aid holding member 18. The cartridge 16 may then be applied to the area of the skin to be shaved. When the user passes the cartridge 16 over the surface of the skin, the shaving aid holding member 18 applies the shaving aid 74 in front of one or more razor blades 42 that shave this area of the skin. That is, the shaving aid 74 may be applied to the skin during shaving with one or more razor blades 42. Alternatively, the user may first attach only the shaving aid holding member 18 to the area of the skin to be shaved. The shaving aid holding member 18 can apply the shaving aid to the entire area of the skin to be shaved before the razor blades 42 are brought into contact with the skin. The user can then attach one or more razor blades 42 of the cartridge 16 to the surface of the skin and shave this area. If necessary, the user can periodically rinse the cartridge 14. With such a protective element 18 holding the shaving aid, the wet shaving device 12 according to any of the embodiments of the present invention, a soft pack 72 with shaving aid or a container 22 with shaving agent.

As shown in FIGS. 4B and 4C, the shaving kit 70 (FIG. 4A) may also include a razor tray 75 and one or more sachets 71 with shaving aid 74. Shaving aid bag 71 may be used in place of tube 72 with shaving aid shown in FIG. 4A. The razor tray 75 may have an upper surface containing a part for storing the wet shaver, in which the razor 12 (not shown) is held and stored between uses. Sachets 71 can be connected to each other with the possibility of detaching them one at a time and attached to the bottom surface of the tray 75 for the razor. At each shaving session, the user can tear one or more sachets 71. The razor tray 75 may include a removable cartridge 77, in which there is one or more sachets connected to each other and attached to a detachable cartridge 77. The removable cartridge 77 can be attached to the bottom surface of the tray 75 with the possibility of detachment. The sachet (s) 71 may have a tear-off or tear-off top 73, as shown in FIG. 4C, for extruding the shaving aid 74. The tear-off top 73 may be sized to allow a narrow strip of shaving aid 74 to be applied to the protective element (such as the protective element 18 holding the shaving aid shown in FIG. 4A). In alternative embodiments, the tear-off top 73 may be sized to allow for a wider strip of shaving aid 74 to cover the entire width of the cartridge 16 (not shown), which, in addition to the security element, includes other components, such as one or more razor blades .

Figure 5 presents a perspective view of the protective element 18 holding the auxiliary means for shaving. The shaving aid holding member 18 may have a front wall 78, a rear wall 76, and a pair of side walls 80 and 82 that can form an elongated groove 84 for holding the shaving aid. The front wall 78 and the rear wall 76 may have a length of from about 25 mm, 30 mm or 35 mm to about 40 mm, 45 mm or 50 mm. The distance from the front wall 78 to the rear wall 76 may be from about 1.5 mm, 2 mm or 2.5 mm to about 3 mm, 3.5 mm or 4 mm. The elongated groove 84 may have a width to length ratio of from about 1: 5, 1: 7, or 1:10 to about 1:15, 1:20, or 1:25. The height of the front wall 78 and the rear wall 76 may be from about 1.0 mm, 1.5 mm or 2.0 mm to about 2.5 mm, 3.0 mm or 3.5 mm for better retention of the shaving aid. The low height provides a shallow depth of the groove that will not be able to hold a sufficient amount of shaving aid. In some embodiments, the elongated groove 84 may be tapered from the front wall 78 to the rear wall 76, that is, the height of the front wall 78 will be greater than the height of the rear wall 76, which can also contribute to better retention and application of shaving aid (s). The shaving aid holding member 18 may be made of an elastomeric material or may be made of a porous material. In some embodiments, the shaving aid holding member 18 may be attached to the cartridge 16 (not shown) by injection molding directly on the cartridge; in other embodiments, it may be attached by other suitable methods, such as gluing or snapping.

6 depicts an alternative embodiment of a cartridge 100 that can be used to apply shaving aid to the skin. The front of the cartridge 100 may include a pair of primary shields 102 and 104 and a shaving aid holding member 106 located between the pair of primary shields 102 and 104. On the cartridge 100, one or two can be installed between the cap 110 and the back of the cartridge 100 more razor blades 108, and on the front of the cartridge 100 a pair of primary protective elements 102 and 104. Each of the pair of primary protective elements 102 and 104 may have a skin-stretching element, for example, a plurality of ribs 112 and 114, extending nnyh parallel to the one or more razor blades 108. The plurality of ribs 112 and 114 can stretch the skin surface being shaved to provide a closer shave. The cartridge 100 can be rotatably attached to the connecting element 116, and the connecting element 115, in turn, can be used to mount the cartridge 100 on a handle (not shown), similar to how the cartridge 16 is mounted on the handle 14 in the embodiments described above. The shaving aid holding member 106 may be used in addition to cover 110 or instead of cover 110; or the cartridge 100 may include a plurality of protective elements 106 holding the shaving aid; or the cartridge 100 may have a protective element 106 holding the shaving aid located at the rear of the cartridge 100.

7 is a perspective view of a shaving aid holding member 106. The shaving aid holding member 106 may have a proximal portion 118 and a distal portion 120. The proximal portion 118 and the distal portion 120 may have a length of from about 25 mm, 30 mm or 35 mm to about 40 mm, 45 mm or 50 mm each one. The proximal portion 118 may have a series of generally round-shaped recesses 122 located along the proximal portion 118 of the protective element 106 holding the shaving aid. The distal portion 120 may have a front wall 124, a rear wall 126 and a plurality of intermediate walls 128, 130 and 132 extending generally along the length of the distal portion 120. The plurality of intermediate walls 128, 130, 132 and 134 may form a plurality of elongated grooves 136, 138, 140 and 142. The height of the front wall 124, the rear wall 126 and the plurality of intermediate walls 128, 130 and 132 may be from about 1.0 mm, 1.5 mm or 2.0 mm to about 2.5 mm, 3.0 mm or 3.5 mm, which may contribute to better retention of the shaving aid. Small height leads to a shallow depth of the grooves and they will not be able to hold a sufficient amount of shaving aid.

On figa and 8B presents a section of the protective element 106 holding the auxiliary means for shaving, on a plane 8-8 (Fig.7). The shaving aid 106 holding the shaving aid may be in the first (compressed) state (FIG. 8B) and in the second (uncompressed, free) state (FIG. 8A). The shaving aid holding member 106 may be in a first (free) state when the cartridge 100 is immersed by the user in a shaving aid container (as shown in FIG. 2), or when the shaving aid is extruded from the tube 72 or sachet 71 (as shown in FIGS. 4A and 4C). The shaving aid holding member 106 may be in a compressed state when the cartridge 100 is pressed by the user against the skin surface during shaving.

The distal portion 120 of the shaving aid holding member 106 may have a generally round body, away from which the intermediate walls 128, 130, 132 and 134 are extended. Although the four intermediate walls 128, 130, 132 and 134 are shown in the drawing , more or fewer walls may be used. When the shaving aid holding member 106 is in a free state, the distance between adjacent intermediate walls 128, 130, 132, and 134 may be from about 0.2 mm, 0.3 mm, or 0.55 mm to about 0, 7 mm, 0.9 mm or 1.0 mm. The free state allows the shaving aid holding member 106 to hold more shaving aid. The shaving aid may be gripped by a generally circular recesses 122 and a plurality of elongated grooves 136, 138, 140 and 142. There may also be a groove 144 formed by a rear wall 126 and an intermediate wall 136, which also grips the shaving aid. The distance between adjacent intermediate walls 128, 130, 132 and 134 can be considered as the width of the grooves. The width of the grooves of the shaving aid holding member 106 may be larger than the width of the groove formed by the pair of primary shields 112 and 114 (FIG. 6) to grip and hold more shaving aid. In some embodiments, the width of the grooves of the shaving aid holding member 106 can be from about 1.5, 2, or 3 times larger to about 4, 5, or 6 times greater than the width of the groove between the primary shields 112 and 114 (Fig.6).

In general, the round recesses 122 of the proximal portion 118 may be in close proximity to the rear wall 126. The round recesses 122 may also be in a free state (FIG. 8A) and in a compressed state (FIG. 8B). In the free state, the generally circular recesses 122 may have a radius from about 0.15 mm, 0.3 mm or 0.55 mm to about 0.7 mm, 0.9 mm or 1.0 mm. In the compressed state, the generally circular recesses 122 can be compressed from about 25%, 30%, or 40% to about 50%, 75%, or even 100%. The shaving aid holding member 106 may be made of an elastomeric material or a porous material that facilitates the compression and release of the shaving aid. The shaving aid holding member 106 may have a Shore A hardness of about 10, 20 or 30 to about 60, 70, or 80. In some embodiments, the shaving aid holding member 106 may be attached. to the cartridge 100 by injection molding directly on the cartridge; in other embodiments, it may be attached by other suitable methods, such as gluing or snapping.

Circular recesses 122 and a plurality of holes 136, 138, 140 and 142 can contribute to better retention of the shaving aid when the cartridge 100 (not shown) is immersed in the container 22 with the shaving aid (as shown in FIG. 2) or when extruded onto it shaving aid from a tube 72 or sachet 71 (as shown in FIGS. 4A and 4C). The recesses 122 and the intermediate walls 128, 130, 132 and 134 prevent the immediate release of the shaving aid when the cartridge 100 (not shown) is applied to the surface of the skin to be shaved. The force with which the shaving aid holding member 106 is squeezed by the surface of the skin presses the intermediate walls 128, 130, 132 and 134 closer together, resulting in a shaving aid being released from the grooves. In some embodiments, the intermediate walls 128, 130, 132 and 134 are pressed against each other so much that they begin to touch each other, and the shaving aid from the elongated grooves 136, 138, 140, 142 and 144 is more and more extruded onto the skin surface. In general, round recesses 122 may also be compressed and shaving aid may also be released from them.

If desired, the embodiments of the invention described above can be implemented individually or in combination with each other. So, for example, the shaving method may include using any of the types of cartridges with protective elements holding the shaving aid described above, or the shaving kit may include using any of the types of cartridges with the protective elements holding the shaving aid described above.
