Description

Description: TECHNICAL FIELD The present invention relates to a method of using a replaceable blade razor for shaving a face in a barber shop, a beauty salon, or a general household.

(Prior Art) FIG. 4 shows an example of how to use a conventional blade razor.
In the spare blade razor A ', the outer peripheral surface of the tip 1a' of the holder 1'which fits and holds the base of the spare blade 2'is square, and the spare blade 2'protrudes from the tip 1a '. Has become. When performing face shaving with such a replaceable blade razor A ', the rectangular tip portion 1a' of the holder 1'is
The blade edge 2a 'of the spare blade 2'protruding from the skin B to be shaved
To the skin B so that the entire blade 2'is almost 45
The beard and downy hairs are caused by shaving the hair in a direction indicated by an arrow a while advancing the hair in a direction indicated by an arrow a, and pulling the skin B in the opposite direction indicated by an arrow b with an open hand. The roots of the raised beard, downy hair, etc. are cut by the blade edge 2a 'of the spare blade 2'which is advanced to be shaving.

As described above, the holder 1'of a normal blade razor merely holds the base of the blade 2'removably, and the outer peripheral surface of the square tip 1a 'of the holder 1'and other The part is configured not to contact B with the skin to be shaved. Therefore, when the outer peripheral surface of the tip portion 1a 'of the holder 1'contacts the skin B, the blade edge 2a' floats away from the skin and it becomes impossible to shave beard or downy hair.

In contrast to such a replacement blade razor, in Japanese Utility Model Laid-Open No. 51-98790, when the blade tip is brought into contact with the skin and the square outer peripheral surface of the tip of the holder is brought into contact with the skin, A safety razor is disclosed in which the length of the blade tip extending from the holder is set to 0.2 to 1 mm so that the blade holds an angle of 10 to 60 degrees with respect to the skin. In this way, if the extension length of the blade tip from the holder is shortened to 1 mm or less, even if the blade tip is in contact with the skin, the square outer peripheral surface of the tip of the holder contacts the skin, The angle of the blade to the skin can be kept constant.

(Problems to be solved by the invention) Without contacting the holder with the skin, or with the square tip of the holder in contact with the skin, at a predetermined angle of 10 to 60 degrees with respect to the skin of the blade The conventional method of using a replacement blade razor to hold and shave the cutting edge along the skin requires great care not to damage the skin with the cutting edge. Further, in order to surely cut the beard or downy hair from the root, it is necessary to pull up the skin with an empty hand to raise the beard or downy hair when the blade edge is moved along the skin.

With such a conventional razor, advanced techniques are required to carry out face shaving without damaging the skin and pulling the skin with the free hand.
It takes a long period of training to acquire the technique.

In the safety razor disclosed in the above publication, it is necessary to move the entire razor in a state where the square outer peripheral surface of the tip of the holder is in contact with the skin. You must be extremely focused on your work.

Even if sufficient care is taken to prevent the cutting edge from digging into the skin, the blade edge of the replacement blade can be shave while being inclined with respect to the skin, so that the skin becomes tight, rough skin, and fluffing occur. There is a fear.

Further, in the safety razor described in the above publication, the outer peripheral surface of the tip portion of the holder is square, and this square outer peripheral surface may contact the skin and cause friction, which may cause discomfort or damage the skin. There is also.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a method of using a replaceable blade razor capable of safely performing face shaving, etc. without requiring advanced techniques, training, and mental concentration. To do. Another object of the present invention is to provide a method of using a replaceable blade razor that does not damage the skin by the blade edge of the replaceable blade and the tip of the holder, and does not cause skin tightness or rough skin. .

(Means for Solving the Problem) A method of using a replaceable blade razor according to the present invention is an arc-shaped expansion that bulges in an arc shape toward the cutting edge on both sides of the tip of a holder that fits and clamps the root of the replacement blade. The protruding portion is provided in a state of being in direct contact with the replacement blade, and when one of the arcuate bulging portions contacts the skin and dents the skin, the polishing surface of the blade edge of the replacement blade A method of using a replacement blade razor in which a certain inclined surface closely follows the skin, and the replacement blade is made substantially parallel to the skin, and one arc-shaped bulge of the tip of the holder is cut into the skin. While adhering to and making the skin hollow,
While maintaining the state in which the inclined surface, which is the polishing surface of the blade of the replacement blade, is closely adhered following the skin, it is characterized by advancing the entire holder along the skin, thereby achieving the above object. To be done.

(Operation) In the method of using the replaceable blade razor of the present invention, the replaceable blade is placed substantially parallel to the skin, and one of the arcuate bulging portions of the tip of the holder and the blade edge of the replaceable blade are placed on the skin. Contact. As a result, due to the arcuate bulging portion in contact with the skin, the soft elastic skin is in a depressed state, and the inclined surface, which is the polishing surface of the blade edge of the replacement blade, is in a closely contacted state following the skin. Keeping such a state,
When the entire holder is advanced along the skin, the arc-shaped outer peripheral surface of the tip of the holder presses the contacting skin forward, and the skin located in front of the skin that the blade edge closely follows Becomes a raised state, and the cutting edge that is in close contact with the skin cuts off the roots of the beard and downy hair that grow on the raised skin.

Since the blade edge is advanced in a state of being in close contact with the skin, there is no possibility that the blade edge will bite into the skin, and there is no risk of pulling the skin or causing rough skin.

(Example) Hereinafter, the Example of this invention is described in detail based on drawing.

FIG. 2 (a) is a side view showing an example of a replacement blade razor that can be used for carrying out the method of the present invention, FIG. 1 (a) is a sectional view thereof, and FIG. 3 is a sectional view showing its use state. In this spare blade razor A, the root of the spare blade 2 is replaceably fitted and sandwiched in the center of the tip 1a of the holder 1. The blade tip 2a of the spare blade 2 is the tip 1a of the holder 1. It is protruding from.

Both side portions of the tip end portion 1a of the holder 1 located on both sides of the replacement blade 2 are arcuate bulges in which the outer peripheral surface bulges in an arcuate shape toward the blade tip 2a.

Unlike the conventional razor, this spare blade razor A is not used in a state in which the blade tip is inclined at a predetermined angle of about 45 degrees with respect to the skin, but as shown in FIG.
With the entire holder 1 in a state substantially parallel to the skin B, one of the arcuate bulges provided on the tip 1a of the holder 1 that holds the root of the replacement blade 2 in contact with the skin B, The whole 1 is advanced along the skin B toward the cutting edge 2a side.

The spare blade razor A is held by the holder 1 in a state in which the blade tip 2a of the spare blade 2 extends from the tip portion 1a of the holder 1 over a length of about 1 mm or more. The spare blade 2 itself is the same as the spare blade used in a conventional safety razor or the like, and the polished inclined surface (polishing surface) of the blade tip 2a has a spread angle of about 5 to 15 degrees.

The holder 1 is provided with a linear inclined surface that is continuous with each arcuate bulge portion provided on the tip end portion 1a and that gradually expands toward the rear end portion side. Then, the central portion of the holder 1 continuous with the inclined surface is in a concave shape.

The straight line connecting the blade edge 2a of the spare blade 2 and the outer peripheral surface of each arcuate bulge provided on the tip portion 1a of the holder 1 is located outside the virtual extension line D of the inclined surface of the blade edge 2a. Cage, third
As shown in the figure, the holder 1 is arranged in a state substantially parallel to the skin B, and one of the arcuate bulges provided on the tip 1a of the holder 1 comes into contact with the skin B so that the skin B When the blade edge 2a is brought into contact with the skin B while denting, the inclined surface, which is the polishing surface of the blade edge 2a, closely adheres to the skin B over the entire extension direction (width direction) of the blade edge 2a, The size and shape of each arcuate bulge with respect to the blade edge 2a are set.

Since the skin B is elastic and soft, it is appropriately recessed by one of the arcuate bulges of the tip 1a of the holder 1 so that the blade edge 2a of the replacement blade 2 extending from the holder 1 The inclined surface becomes in a state of closely adhering to the skin B along the entire extending direction of the cutting edge 2a,
The angle of 2a with respect to the skin B is 0 degree. Naturally, the cutting edge 2a
The arc shape of each arc-shaped bulging part depends on the extension length from the holder 1, the divergence angle of the cutting edge 2a, the width dimension of the inclined surface, and the like.
The size etc. are changed appropriately.

FIGS. 1 (b) and (c) are cross-sectional views showing another example of the holder 1 of the disposable blade razor used for carrying out the method of the present invention. The shape of the holder 1 of each blade razor A shown in FIGS. 1 (b) and (c) is different from the shape of the holder 1 of the blade razor A shown in FIG. 1 (a). However, each spare blade razor A shown in FIGS. 1 (b) and (c)
However, the relationship between each arcuate bulge portion provided on the outer peripheral surface of the tip 1a of the holder 1 and the cutting edge 2a is the same as in the blade razor A shown in FIG. When the blade tip 2a is brought into contact with the skin B while being arranged in a state substantially parallel to the other, and any one of the arcuate bulges of the tip portion 1a of the holder 1 is brought into contact with the skin B to make the skin B depressed. In addition, the inclined surface, which is the polishing surface of the cutting edge 2a, closely contacts the skin B over the entire width direction of the cutting edge 2a.

The holder 1 shown in FIG. 1 (b) has arcuate bulges on both sides of the tip 1a so as to bulge toward the cutting edge 2a, and the outer peripheral surface of each arcuate bulge A linear inclined surface that gradually and gradually expands toward the rear end side continues to the rear end of the holder 1.

The holder 1 shown in FIG. 1 (c) has a cutting edge 2a with an arcuate outer peripheral surface on both sides of the tip 1a, as in FIG. 1 (b).
The holder 1 has an arcuate bulge that bulges to the side, and the holder 1 is slightly recessed in the center near the tip 1a.

Further, the spare blade razor used for carrying out the method of the present invention is
A so-called T-shaped razor may be used as shown in FIG. 2 (b). The shape of the handle and holder of the razor is not limited to those shown.

The replaceable blade 2 may be either a single-edged blade or a double-edged blade, and the length and thickness of the replaceable blade 2, the length and thickness of the cutting edge 2a, the spread angle of the cutting edge 2a, etc., are intended for use and preferred by a shave. It is selected according to the customer's wishes. Then, in accordance with the thickness of the replacement blade 2, the spread angle of the blade edge 2a, etc., the above-mentioned blade edge 2a
So that the outer peripheral surface provided on the tip 1a of the holder 1 has a relationship with each arcuate bulge having an arcuate shape.
The shape, size, etc. of each arcuate bulge are set.

In the blade razor A having such a structure, as shown in FIG. 3, when shaving a beard such as a face or a nape of the neck or a hair C such as downy hair, the holder 1 is made substantially parallel to the skin B, and the holder 1
While the outer peripheral surface of the arcuate bulging portion formed on one side of the tip portion 1a is brought into contact with the soft elastic skin B, the cutting edge 2a is brought into contact with the skin B. Thereby, the tip 1a of the holder 1
The arcuate bulge formed on one side pushes the skin B, and the skin B is depressed in a concave shape. At this time,
The arc-shaped bulging portion of the holder 1 which is in contact with the skin B has a cutting edge 2a.
Since it is located outside the extension of the inclined surface, the cutting edge
The entire inclined surface of 2a follows the soft skin B having elasticity and is in a close contact state.

In this state, when the entire spare blade razor A is advanced along the skin B toward the blade tip 2a side of the spare blade 2, the holder 1
The outer peripheral surface on one side of the tip 1a of the
The arcuate bulging portion bulging to the 2a side advances while contacting the skin B, and presses the skin B forward. The skin behind the replaceable blade 2 is pulled in the direction opposite to the forward direction of the replaceable blade razor A shown by the arrow b to be in a taut state.
The skin B in front of the skin B is raised, and the root of the hair C such as beard or downy hair of the skin B is surely cut by falling down on the cutting edge 2a which closely follows the skin B and advances. .

When the entire holder 1 is advanced along the skin B, the arcuate bulging portion having an arcuate outer peripheral surface formed on one side of the tip portion 1a of the holder 1 contacting the skin B causes the skin B to be recessed. While maintaining the state of being pressed forward by the blade, the entire inclined surface of the cutting edge 2a is advanced in a state of closely adhering to the skin B, and the hair C such as beard or downy hair of the skin B in front of the cutting edge 2a is sequentially It is cut from the root by 2a.

The cutting edge 2a cuts the hair C such as beard or downy hair in a state where the entire inclined surface is in close contact with the skin B and follows the cutting edge 2a.
There is no possibility of damaging the skin B, and there is no possibility of causing rough skin or tightness of the skin.

(Effects of the Invention) The method of using the replaceable blade razor according to the present invention thus allows the skin to be removed by one of the arcuate bulging portions provided on both sides of the tip of the holder so as to bulge toward the blade tip side. While denting, with the inclined surface of the cutting edge closely adhering to the skin,
Since the holder is moved forward, there is no risk of the skin being damaged by the cutting edge, and there is no risk of rough skin, skin drag, bleeding, or the like.

In addition, the arcuate bulge formed on one side of the tip of the holder that came into contact with the skin caused the skin in front of the blade to bulge when the replacement blade was shaving in order to leave the skin depressed. It is not necessary to pull the skin with an empty hand because the beard or the root of the downy hair will fall into the state and the root of the hair will fall down firmly on the cutting edge that is in close contact with the skin and be surely cut.

As a result, the method of using the replaceable blade razor of the present invention enables shaving and the like without requiring high skill and mental concentration, does not require a long time for mastering, and is safe even at home. It is possible to carry out shaving and the like.

The arcuate bulges formed on both sides of the tip of the holder that slides against the skin with the skin depressed, because the outer peripheral surface has an arcuate shape, there is no risk of damaging the skin, and conversely, The arcuate bulging portion massages the skin, so that a comfortable feeling can be obtained.
