Description

FIELD OF THE INVENTION

The present invention relates to a hair iron cover member and a hair iron.

BACKGROUND OF THE INVENTION

A heat reactive liquid agent for repairing hair has frequently been used in recent years. The liquid agent is used by being applied to the hair and heated by a far-infrared ray warmer.
However, the far-infrared ray warmer has a problem that heat is transmitted only to the surface of the hair and the repairability is reduced.
Accordingly, in order to solve such a problem, a hair iron as described in Patent Document 1 is used. When such a hair iron is used, heat is uniformly transmitted to the hair and thus the repairability can be enhanced.

SUMMARY OF THE INVENTION

Technical Problem

Incidentally, in the hair iron as described above, a hair iron cover member (non-metallic pressurizing member) molded of a heat resistant silicone rubber is attached to a heating portion of the hair iron. When such a hair iron cover member is attached to the heating portion of the hair iron, recessed portions provided to both sides of a distal end portion and a rear end portion of the hair iron cover member are respectively inserted with protruding portions provided to both sides of a rod case at a distal end portion and a rear end portion of the heating portion of the hair iron, thereby allowing the hair iron cover member to be attached to the heating portion.
However, when the recessed portions provided to the distal end portion of the hair iron cover member are inserted with the protruding portions provided to the distal end portion of the heating portion of the hair iron, it is difficult to fit the recessed portions of the distal end portion of the hair iron cover member to the protruding portions provided to the distal end portion of the heating portion of the hair iron, so that there is a problem that the distal end portion of the hair iron cover member may be torn and the hair iron cover member may be damaged.
Accordingly, in view of the foregoing problem, an object of the present invention is to provide a hair iron cover member and a hair iron capable of reducing damage.

Solution to the Problem

The foregoing object of the present invention is achieved by the following means. It is noted that reference signs of an embodiment to be described later are added in parentheses, but the present invention should not be limited thereto.
A hair iron cover member (1) according to the first aspect is characterized by including a hair iron cover member body (10) attached to a heating portion (23) of a hair iron (2), wherein the hair iron cover member body (10) has a distal end portion (10 a 3) formed into a flat shape with no steps.
According to the second aspect of the present invention, the hair iron cover member (1) according to the foregoing first aspect is characterized in that ridge portions (10 b 2) are provided on an outer peripheral surface (lower surface 10 b 1) of the hair iron cover member body (10) at appropriate intervals along the width direction of the hair iron cover member body (10).
Further, according to the third aspect of the present invention, the hair iron cover member (1) according to the foregoing first aspect is characterized in that the hair iron cover member body (10) has a shape having an upper portion (10 a), a lower portion (10 b), and side portions (a left side portion 10 c and a right side portion 10 d), and
the side portions (the left side portion 10 c and the right side portion 10 d) of the hair iron cover member body (10) have a thickness (t1) formed so as to be thicker than a thickness (t2) of the upper portion (10 a) and the lower portion (10 b) of the hair iron cover member body (10).
On the other hand, according to the fourth aspect of the present invention, there is provided a hair iron (2) using the hair iron cover member (1) according to the foregoing first aspect.

Advantageous Effects of the Invention

Next, advantageous effects of the present invention will be described with reference signs in the drawings. It is noted that reference signs of an embodiment to be described later are added in parentheses, but the present invention should not be limited thereto.
According to the first aspect of the present invention, the distal end portion (10 a 3) of the hair iron cover member body (10) is formed into a flat shape with no steps, so that there is no need to fit recessed portions and protruding portions as in the conventional case. Therefore, the situation in which the distal end portion (10 a 3) of the hair iron cover member body (10) is torn can be reduced.
Thus, according to the present invention, damage can be reduced.
In addition, according to the second aspect of the present invention, the ridge portions (10 b 2) are provided on the outer peripheral surface (lower surface 10 bi) of the hair iron cover member body (10) along the width direction of the hair iron cover member body (10) at appropriate intervals, so that when the treatment of inward or outward curling is performed, the treatment can be performed smoothly while adjusting hair tips.
Further, according to the third aspect of the present invention, the side portions (the left side portion 10 c and the right side portion 10 d) of the hair iron cover member body (10) have a thickness (t1) formed so as to be thicker than a thickness (t2) of the upper portion (10 a) and the lower portion (10 b) of the hair iron cover member body (10), so that the situation in which a person to be treated feels uncomfortable or uneasy can be reduced.
On the other hand, according to the fourth aspect of the present invention, the hair iron (2) using the hair iron cover member (1) according to the foregoing first aspect is provided, so that the same advantageous effects as those of the hair iron cover member (1) according to the foregoing first aspect can be exerted.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, an embodiment of a hair iron cover member according to the present invention will be described specifically with reference to the drawings. It is noted that when vertical and horizontal directions are indicated, it shall mean vertical and horizontal directions when viewed from the front of the figure.
As shown in FIG. 1 and FIG. 2, a hair iron cover member 1 has a hair iron cover member body 10 having a substantially vertically long semicircular shape in a longitudinal sectional view, in particular, as shown in FIG. 2(a). The hair iron cover member body 10 is formed of an elastically deformable member (for example, heat resistant silicone rubber, etc.), formed into a hollow shape as shown in FIG. 2(a), and has a rear part formed with an opening 11. Further, as shown in FIG. 2(a), an upper surface 10 a 1 of an upper portion 10 a of the hair iron cover member body 10 is formed with a recessed step portion having a step at a rear end portion 10 a 2, and from the rear end portion 10 a 2 having the recessed step portion to a distal end portion 10 a 3, a flat portion with no steps is formed. That is, the distal end portion 10 a 3 of the hair iron cover member body 10 is formed into a flat shape with no steps.
On the other hand, as shown in FIG. 2(a), ridge portions 10 b 2 are integrally formed on an outer peripheral surface (lower surface 10 b 1) of a lower portion 10 b of the hair iron cover member body 10 along the width direction of the hair iron cover member body 10 at predetermined intervals toward the outward direction.
On the other hand, as shown in FIG. 2(b), a left side portion 10 c and a right side portion 10 d of the hair iron cover member body 10 have a thickness t1 formed so as to be thicker than a thickness t2 of the upper portion 10 a and the lower portion 10 b of the hair iron cover member body 10. Specifically, the thickness t1 is formed to be about 0.9 mm and the thickness t2 is formed to be about 0.5 mm.
Thus, the hair iron cover member 1 formed as above is attached to a hair iron 2 to be used as shown in FIG. 1.
The hair iron 2 has a pair of long substantially rectangular rods 20 as shown in FIG. 1, and the pair of rods 20 have rear end portions 20 a mutually connected and can be rotated around a hinge portion 21 in directions of arrows P1 and P2.
On the other hand, as shown in FIG. 1, the rod 20 is provided with a grip portion 22 which can be gripped by a user on the rear end portion 20 a side and provided with a heating portion 23 on a distal end portion 20 b side. The heating portion 23 is provided with a heater (not shown) inside, and a rectangular metal heating plate 23 a heated by transmitting the heat energy of the heater is provided. The heating plate 23 a has a distal end portion 23 a 1 supported by a first support portion 23 b and has a rear end portion 23 a 2 supported by a second support portion 23 c as shown in FIG. 1. The first support portion 23 b is formed so as to be flush with an upper surface 23 a 3 of the heating plate 23 a and formed into a thick semicircular shape as shown in FIG. 1 and FIG. 2(a). On the other hand, the second support portion 23 c is formed so that an upper surface 23 c 1 comes to a position lower than the upper surface 23 a 3 of the heating plate 23 a and formed into a thick rectangular shape as shown in FIG. 1 and FIG. 2(a). As a result, a step portion is generated between the rear end portion 23 a 2 of the heating plate 23 a and the upper surface 23 c 1 of the second support portion 23 c. The heater (not shown) generates heat by electric energy supplied from a power supply cord 24 connected to a commercial power source (not shown).
Thus, in each of the pair of rods 20 of the hair iron 2 formed in this manner, as shown in FIG. 1, the hair iron cover member 1 is attached to the heating portion 23 (distal end portion 20 b) of the rod 20. More specifically, the hair iron cover member body 10 is inserted with the distal end portion 20 b of the rod 20 from the opening 11 formed in the rear part of the hair iron cover member body 10 (see arrow P3). As a result, as shown in FIG. 2(a), the recessed step portion formed at the rear end portion 10 a 2 of the hair iron cover member body 10 is closely fitted to the step portion generated between the rear end portion 23 a 2 of the heating plate 23 a and the upper surface 23 c 1 of the second support portion 23 c, and the hair iron cover member 1 is attached to the heating portion 23 (distal end portion 20 b) of the rod 20.
At this time, since the distal end portion 10 a 3 of the hair iron cover member body 10 is formed into a flat shape with no steps, there is no need to fit recessed portions and protruding portions as in the conventional case. Therefore, the situation in which the distal end portion 10 a 3 of the hair iron cover member body 10 is tom can be reduced.
In this respect, to the distal end portion 20 b of the rod 20 located at the upper part shown in FIG. 1, a hair iron cover member 1 obtained by rotating 180 degrees the hair iron cover member 1 attached to the distal end portion 20 b of the rod 20 located at the lower part shown in FIG. 1 is attached.
Thus, the hair iron 2 to which the hair iron cover members 1 are attached to the heating portions 23 (distal end portions 20 b) of the rods 20 in this manner is used as shown in FIG. 3. That is, as shown in FIG. 3(a), mainly, a heat reactive liquid agent for repairing hair is applied to wet hair H, and the wet hair H to which the liquid agent is applied is sandwiched between the upper surfaces 10 a 1 of the pair of rods 20 attached with the hair iron cover members 1 and is heated. As a result, treatment such as a permanent wave can be performed.
Incidentally, at this time, in the hair iron 2 to which the hair iron cover members 1 are attached, the heating plates 23 a are heated by heaters (not shown) and the heat of the heating plates 23 a is transmitted to the hair iron cover members 1 attached to the heating portions 23 (distal end portions 20 b) of the rods 20. As a result, when the wet hair H is sandwiched between the upper surfaces 10 a 1 of the pair of rods 20 attached with the hair iron cover members 1 and is heated, the heat of the heating plates 23 a is not directly transmitted to the wet hair H, but is transmitted via the hair iron cover members 1. Thus, even if the wet hair H is sandwiched between the upper surfaces 10 a 1 of the pair of rods 20 attached with the hair iron cover members 1 and is heated, an instantaneous evaporation phenomenon does not occur and the heat is uniformly transmitted to the hair. As a result, the repairability of the hair H can be enhanced.
Incidentally, when the wet hair H is sandwiched between the upper surfaces 10 a 1 of the pair of rods 20 attached with the hair iron cover members 1 and is heated, water droplets W of the wet hair H are attached on an outer peripheral surface 10 c 1 of the left side portion 10 c or an outer peripheral surface 10 d 1 of the right side portion 10 d of the hair iron cover member body 10 as shown in FIG. 3(a). At this time, when the heat of the heating plates 23 a is transmitted to the hair iron cover members 1, the water droplets W are evaporated by the heat, and the sizzling sound at the time of the evaporation may make the person to be treated feel uncomfortable or uneasy.
Accordingly, in the present embodiment, in order to reduce the situation in which the person to be treated feels uncomfortable or uneasy, as shown in FIG. 2(b), the left side portion 10 c and the right side portion 10 d of the hair iron cover member body 10 have the thickness t1 formed so as to be thicker than the thickness t2 of the upper portion 10 a and the lower portion 10 b of the hair iron cover member body 10. As a result, when the heat of the heating plate 23 a is transmitted to the hair iron cover member 1, the heat is less likely to be transmitted to the outer peripheral surface 10 c 1 of the left side portion 10 c and the outer peripheral surface 10 d 1 of the right side portion 10 d of the hair iron cover member body 10 by the increased thickness. Therefore, as shown in FIG. 3(a), even if the water droplets W of the wet hair H are attached on the outer peripheral surface 10 c 1 of the left side portion 10 c or the outer peripheral surface 10 d 1 of the right side portion 10 d of the hair iron cover member body 10, the water droplets W are less likely to be evaporated, so that the situation in which the person to be treated feels uncomfortable or uneasy can be reduced.
On the other hand, when the wet hair H is sandwiched between the upper surfaces 10 a 1 of the pair of rods 20 attached with the hair iron cover members 1 and is heated, the treatment of inward or outward curling may be performed. Therefore, in the present embodiment, in order that the treatment can be performed smoothly while adjusting the hair tips when the treatment of inward or outward curling is performed, ridge portions 10 b 2 are integrally formed on the outer peripheral surface (lower surface 10 b 1) of the lower portion 10 b of the hair iron cover member body 10 along the width direction of the hair iron cover member body 10 at predetermined intervals toward the outward direction as shown in FIG. 1 and FIG. 2(a). That is, for example when performing the treatment of inward curling, as shown in FIG. 3(a), the hair iron 2 is rotated in the direction of arrow P4 with the wet hair H sandwiched between the upper surfaces 10 a 1 of the pair of rods 20 attached with the hair iron cover members 1. As a result, as shown in FIG. 3(b), the ridge portions 10 b 2 formed on the outer peripheral surface (lower surface 10 b 1) of the lower portion 10 b of the hair iron cover member body 10 cut in between the wet hair H. Then, as the ridge portions 10 b 2 cut in between the hair H, the wet hair H in a predetermined bundle Ha is placed between a plurality of ridge portions 10 b 2. Thus, the wet hair H in the predetermined bundle Ha is placed between the plurality of ridge portions 10 b 2 in this manner, so that the treatment of inward curling can be performed smoothly while adjusting the hair tips. In this respect, when performing the treatment of outward curling, the hair iron 2 is only required to be rotated in the direction opposite to the direction of arrow P4 shown in FIG. 3(a).
Thus, if the ridge portions 10 b 2 are integrally formed on the outer peripheral surface (lower surface 10 b 1) of the lower portion 10 b of the hair iron cover member body 10 along the width direction of the hair iron cover member body 10 at predetermined intervals toward the outward direction, the treatment can be performed smoothly while adjusting the hair tips when the treatment of inward or outward curling is performed.
Thus, according to the present embodiment described above, damage to the hair iron cover member 1 can be reduced.
It is noted that the shape and the like shown in the present embodiment are merely examples, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims. For example, the example in which the ridge portions 10 b 2 of the hair iron cover member 1 are formed at predetermined intervals is shown. However, without being limited thereto, the ridge portions 10 b 2 may be formed at random. Further, the example in which the ridge portions 10 b 2 are integrally formed with the hair iron cover member body 10 is shown. However, without being limited thereto, the ridge portions 10 b 2 may be formed separately. Further, the example in which the ridge portions 10 b 2 are formed on the outer peripheral surface (lower surface 10 b 1) of the lower portion 10 b of the hair iron cover member body 10 is shown. However, without being limited thereto, the ridge portions 10 b 2 may be formed on an outer peripheral surface (upper surface 10 a 1) of the upper portion 10 a of the hair iron cover member body 10.
On the other hand, the hair iron 2 shown in the present embodiment is merely an example. When the hair iron cover member 1 is attached, it may be attached to any hair iron.
Further, in the present embodiment, the example in which the hair iron 2 attached with the hair iron cover members 1 is used for the wet hair H is shown. However, without being limited thereto, it may be used for dry hair.
