Abstract
Description
[Technical Field]
[0001] The present invention relates to a razor tool. [Background technology]
[0002] Razors such as those shown in Patent Document 1 have been used in the past. Such razors include a head (replaceable blade) having a blade, and a handle to which the head is attached in a detachable manner. When the blade loses its sharpness, the head can be replaced, allowing the handle to be used for a long period of time. Therefore, by reusing the handle, it is possible to promote the effective use of resources for the handle. Meanwhile, razors with a head and handle integrated into one unit are inexpensive and are provided at lodging facilities at travel destinations, or can be easily purchased at convenience stores, where they are used a few times and then discarded.
[0003] These razors are rarely used alone, and generally require shaving fluids such as shaving gel or shaving cream, which must be prepared separately from the razor. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 63-48569 Summary of the Invention [Problem to be solved by the invention]
[0005] For example, if a lodging facility does not have a razor and a user needs to suddenly purchase one, the user must purchase the razor and the razor fluid package separately. However, the razor fluid container is relatively large compared to the razor itself. If the user stays at the lodging facility for several days and uses the razor only a few times, the user may end up with excess razor fluid, which may then be discarded. Furthermore, if the user prepares and brings their own razor to the lodging facility, the user may forget the razor fluid. Furthermore, if the user suddenly uses an unfamiliar razor at the lodging facility, the contact of the razor with the skin may vary significantly, potentially resulting in skin injury.
[0006] Therefore, the present invention has been made to solve the above problems, and its object is to provide a razor that is less likely to damage the skin and can be used without forgetting to use the appropriate amount of razor fluid. [Means for solving the problem]
[0007] The present invention solves the above problem by providing a razor tool comprising a handle and a head supported at the tip of the handle and having one or more blades, wherein the handle further comprises a storage section that supports the tip, is held in the user's hand, stores razor fluid, and has an outlet that allows the razor fluid to be pushed out by the user's pressing force, and the storage section has lower rigidity than the tip.
[0008] In the present invention, the handle further includes a storage section that supports the tip, is held by the user's hand, and stores razor fluid. The storage section has an outlet that allows the razor fluid to be expelled by the user's pressure. In other words, since the handle stores razor fluid, the user can ensure that the appropriate amount of razor fluid is always ready and can carry it with the razor. Furthermore, since the razor fluid can be expelled from the storage section by the user's force, the user can adjust the amount of razor fluid used. Furthermore, the storage section has a lower rigidity than the tip. Therefore, when the force acting on the user's skin fluctuates significantly, the storage section deforms without disrupting the positional relationship between the blade head and the tip, thereby equalizing the large fluctuations in force acting on the skin. [Effects of the Invention]
[0009] According to the present invention, it is possible to provide a razor that is less likely to injure the skin and that can be used without forgetting to use the appropriate amount of razor fluid. [Brief explanation of the drawings]

[Figure 7]Schematic front views showing variations of the storage section of the razor tool (FIG. 1A is a view of the first embodiment, and FIG. 2B is a view of the second embodiment) DETAILED DESCRIPTION OF THE INVENTION
[0011] An example of the first embodiment of the present invention will be described in detail below with reference to FIGS.
[0012] First, the schematic configuration of a razor tool 100 according to this embodiment will be described with reference to FIG.
[0013] The razor tool 100 comprises a handle 102 and a head 104 supported at a tip 106 of the handle 102 and having a first cutting edge 112 and a second cutting edge 114 (one or more cutting edges). Next, the components of the razor tool 100 will be described in detail.
[0014] As shown in FIGS. 1, 2 and 3, the handle 102 includes a tip portion 106 and a storage portion 108.
[0015] The tip portion 106 is made of, for example, ABS resin (a resin having the properties of acrylonitrile, butadiene, and styrene), and as shown in FIGS. 2 and 3, integrally includes a rotation support portion 106A, a bending portion 106B, and a connecting portion 106C. The rotation support portion 106A is a rectangular parallelepiped member that pivotally supports the head portion 104. As shown in FIG. 4(B), a support surface 106AA of the rotation support portion 106A facing the head portion is provided with convex portions 106AB at 90-degree intervals around a central through-hole 106AC. The bending portion 106B is a member whose tip is branched into two and is connected to both ends of the rotation support portion 106. As shown in FIG. 3, the bending portion 106B is a member that tilts the direction in which the rotation support portion 106A faces (axis P) by a predetermined angle α with respect to the axis O of the storage portion 108. That is, the tip portion 106 is configured to include a bending portion 106B that inclines the head portion 104 at a predetermined angle α with respect to the axial direction O of the storage portion 108. The connecting portion 106C is a member that is connected to the bending portion 106B, and is a member that is fitted into and supported in the storage portion 108.
[0016] The storage section 108 is made of, for example, low-density polyethylene (LDPE) resin (or polypropylene (PP) resin), which is a material that has excellent transparency and flexibility, as well as high tensile strength, tear strength, and impact resistance, and is less rigid than the tip section 106. As shown in Figures 2 and 3, the storage section 108 supports the tip section 106, is held by the user's hand, stores the razor fluid DD, and has an outlet 108C that allows the razor fluid DD to be pushed out by the user's pressing force. Specifically, the storage section 108 has a connection end 108A, a grip section 108B, an outlet 108C, and a cap section 108D.
[0017] As shown in FIG. 3, the connecting end 108A covers the outer periphery of the connecting portion 106C and fits into the connecting portion 106C (note that the connecting portion 106C and the connecting end 108A may simply fit together, or may be bonded with an adhesive). The gripping portion 108B has an internal space that is filled with a razor fluid DD, such as shaving gel or pressure-applied shaving cream. The outlet 108C is connected to the internal space of the gripping portion 108B, and applying pressure to the gripping portion 108B causes the razor fluid DD to be discharged to the outside. Furthermore, when a certain amount of the razor fluid DD has been discharged to the outside, the distorted gripping portion 108B attempts to return to its original cylindrical shape (or the user attempts to return it), causing air to be drawn in through the outlet 108C (when the cap portion 108D is open). A screw groove is provided on the outer periphery of outlet 108C, and is adapted to screw into a screw groove provided on the inside of cap portion 108D. This allows cap portion 108D to close outlet 108C. Therefore, by changing the degree of air filling in storage portion 108 and sealing the inside of storage portion 108 with cap portion 108D, the flexibility of storage portion 108 can be changed.
[0018] As shown in FIG. 3, the head portion 104 includes a casing 110, a first cutting edge portion 112, a second cutting edge portion 114, a first spacer 116, a second spacer 118, and a connecting portion 120.
[0019] The casing 110 is made of, for example, ABS resin (or may be made of PP resin, etc.), and has an opening 110A therein for arranging the first cutting edge 112, the second cutting edge 114, the first spacer 116, and the second spacer 118. The opening 110A is provided by obliquely penetrating the front and back sides of the casing 110. The first cutting edge 112 and the second cutting edge 114 are made of, for example, stainless steel and have the same shape, and are arranged so that their cutting edges are on the front side of the casing 110.
[0020] As shown in FIG. 3, the first spacer 116 is disposed on the back surface of the first cutting edge portion 112 (i.e., between the first cutting edge portion 112 and the second cutting edge portion 114), and the second spacer 118 is disposed on the back surface of the second cutting edge portion 114. The first spacer 116 and the second spacer 118 are made of, for example, PP resin (or polyethylene (PE) resin), and have the same shape. As shown in FIGS. 6(A) and 6(B), the first spacer 116 (second spacer 118) includes a tip portion 116A (118A), a push-out portion 116B (118B), a button portion 116C (118C), a spring portion 116D (118D), and an attachment portion 116E (118E), all of which are integrally molded.
[0021] As shown in FIGS. 6A and 6B, the tip portion 116A (118A) is an end portion that is slightly narrower than the width of the cutting edge of the first blade portion 112 (second blade portion 114). The push-out portion 116B (118B) is provided between the tip portion 116A (118A) and the button portion 116C (118C). The button portion 116C (118C) is a portion that a user presses when pushing the tip portion 116A (118A) beyond the cutting edge of the first blade portion 112 (second blade portion 114). As shown in FIG. 3, the button portion 116C (118C) is thicker than the push-out portion 116B (118B) and other portions, which makes it easier for the user to use and prevents the spring portion 116D (118D) from overstretching. The spring portion 116D (118D) is an elastic member used to move the tip portion 116A (118A) in the direction toward the first blade portion 112 (second blade portion 114). The attachment portion 116E (118E) is a member for attaching the first spacer 116 (second spacer 118) to the opening 114.
[0022] That is, the head 104 is configured to include spacers (first spacer 116 and second spacer 118) on the back surface of the one or more blade portions (first blade portion 112 and second blade portion 114) that are movable in the direction in which the one or more blade portions (first blade portion 112 and second blade portion 114) move. As a result, when the user is not pressing the button portion 116C (118C), the tip portion 116A (118A) is positioned inside the cutting edge of the first blade portion 112 (second blade portion 114) as shown in FIG. 6(A). On the other hand, when the user is pressing the button portion 116C (118C), the tip portion 116A (118A) is positioned outside the cutting edge of the first blade portion 112 (second blade portion 114) as shown in FIG. 6(B).
[0023] As shown in Fig. 3, the connecting portion 120 is disposed on the rear side of the casing 110 and is a member supported by the connecting end portion 106A. As shown in Fig. 4(A), a split pin 120B is provided at the center of the connecting portion 120 to be fitted into a through hole 106AC of the connecting end portion 106A, and a barb 120C is provided at the tip of the split pin 120B to prevent the split pin 120 from easily falling out of the through hole 106AC. In the connecting portion 120, the connecting surface 120A that abuts against the support surface 106AA of the connecting end portion 106A has recesses 120AA provided at 90-degree intervals around the split pin 120B, which correspond to the protrusions 106AB provided on the support surface 106AA.
[0024] Therefore, the razor tool 100 can be changed from the state shown in FIG. 5(A), for example, used for shaving, to the state shown in FIG. 5(B), for example, used for removing unwanted body hair, by manually rotating the head 104 90 degrees clockwise (or counterclockwise) relative to the handle 102. Similarly, the razor tool 100 can be changed from the state shown in FIG. 5(B) to the state shown in FIG. 5(C), from the state shown in FIG. 5(C) to the state shown in FIG. 5(D), and from the state shown in FIG. 5(D) to the state shown in FIG. 5(A) to assume each of these states. That is, the tip portion 106 rotatably supports the head 104, and the head 104 can be fixed at a predetermined angle. In this embodiment, the rotation center Q of the head 104 is located exactly at the cutting edge of the first cutting portion 112 and at the center of the width of the first cutting portion 112, as shown in FIGS. 5(A) to 5(D). However, it is more preferable that the rotation center Q of the head 104 be at the center position between the cutting edge of the first blade portion 112 and the cutting edge of the second blade portion 114 and at the center position of the width of the first blade portion 112 (second blade portion 114), but this is not limited to this.
[0025] Thus, in this embodiment, the handle 102 further includes a storage section 108 that supports the tip end 106, is held by the user's hand, stores razor fluid DD, and has an outlet 108C that allows the razor fluid DD to be expelled by the user's pressing force. In other words, since the handle 102 stores razor fluid DD, the user can ensure that an appropriate amount of razor fluid DD is always ready and can carry it with the razor tool 100. Furthermore, since the razor fluid DD can be expelled from the storage section 108 by the user's force, the user can adjust the amount of razor fluid DD used. Furthermore, the storage section 108 has a lower rigidity than the tip end 106. Therefore, when the force acting on the user's skin fluctuates significantly, the storage section 108 can deform to even out the large fluctuations in force acting on the skin without disrupting the relative positions of the head 104, where the first and second blades 112 and 114 are located, and the tip end 106.
[0026] Furthermore, in this embodiment, the cap portion 108D is provided, and the flexibility of the storage portion 108 can be changed by adjusting the amount of air filled in the storage portion 108 and sealing the interior of the storage portion 108 with the cap portion 108D. This makes it possible to adjust the softness with which the first blade portion 112 and the second blade portion 114 contact the user's skin, without being affected by the amount of razor fluid DD used. However, this is not limiting, and a configuration in which there is no cap portion and the storage portion cannot be sealed may also be used.
[0027] Furthermore, in this embodiment, the tip portion 106 includes a bending portion 106B that tilts the head portion 104 at a predetermined angle α with respect to the axial direction O of the storage portion 108. Therefore, the predetermined angle α at which the head portion is tilted is constantly maintained regardless of whether or not there is a load on the head portion 104, and as a result, the user can stably control how the head portion 104 is placed against the skin. However, this is not limiting, and the bending portion may not be provided.
[0028] Furthermore, in this embodiment, the tip portion 106 rotatably supports the head portion 104, and the head portion 104 can be fixed in 90-degree increments (at a predetermined angle α). Therefore, the razor tool 100 can be transformed into a form optimal for shaving, while also being able to be modified into a form optimal for simply using it as a razor to remove unwanted hair. However, this is not a limitation, and the tip portion does not have to rotatably support the head portion. Furthermore, even if the tip portion rotatably supports the head portion, it does not have to be fixable in 90-degree increments as in this embodiment. The head portion may be fixed at that rotation angle using, for example, a bolt and nut.
[0029] Furthermore, in this embodiment, the head 104 is provided with a first spacer 116 and a second spacer 118 on the rear surfaces of the first blade portion 112 and the second blade portion 114 (one or more blade portions), which are movable in the direction of the first blade portion 112 and the second blade portion 114. This makes it possible to easily remove whiskers and unwanted hair that get stuck behind the first blade portion 112 and the second blade portion 114. This allows the razor tool 100 to be used stably multiple times without being affected by clogging. However, this is not limiting, and a spacer may be provided on the rear surface of either the first blade portion or the second blade portion, or a spacer may not be provided on either rear surface. Alternatively, a spacer may be provided on the front surface of the blade portion.
[0030] Therefore, according to this embodiment, it is possible to provide a razor 100 that is gentle on the skin and allows the user to use the razor without forgetting to take the appropriate amount of razor fluid DD. The razor 100 as a product is, like conventional razors, disposable after multiple uses. Therefore, unlike conventional razors that require a separate razor fluid DD, the razor 100 and the razor fluid DD are integrated into one razor. This means that the product packaging can be reduced to one, which is environmentally friendly and contributes significantly to the SDGs.
[0031] Although the present invention has been described using the first embodiment, the present invention is not limited to the first embodiment. In other words, it goes without saying that improvements and design changes are possible within the scope of the present invention.
[0032] For example, in the first embodiment, the storage compartment 108 contained a razor fluid DD, such as shaving gel or shaving cream, which softens and smooths beard hair (including unwanted hair), but the present invention is not limited to this. For example, the storage compartment may further contain a skin care agent, such as a skin lotion, which moisturizes the skin after shaving. For example, the razor tool 100 of the first embodiment is shown in FIG. 7(A), but it may also be a razor tool 200 of a second embodiment, as shown in FIG. 7(B). In the second embodiment, the head 204 has the same configuration as the head 104, but the storage compartment 208 of the handle 202 has two internal spaces and is provided with two cap portions 208D. One space contains the shaving gel or shaving cream shown in the first embodiment, and the other space contains a skin care agent. This eliminates the need to prepare a separate skin care agent, making the second embodiment more portable and environmentally friendly.
[0033] In the above embodiment, there are two blades, but the present invention is not limited to this, and there may be one blade, or three or more blades. [Industrial Applicability]
[0034] The present invention is suitable for application mainly to a razor tool that is easy to carry. [Explanation of symbols]
