この考案は電気かみそりに形成された外刃、詳

リツトで効果的に補捉剪断させるようにしたもの
がある。 For example, in this type of outer cutter used in a reciprocating electric shaver, a protrusion is formed on the main surface of the outer cutter base made of the final electrodeposited layer, and a large number of slits are formed in the protrusion. Accordingly, there is a device in which long hairs that tend to lie down are made to stand up on the ridges, and are effectively captured and sheared using the slits.
ところで、上記スリツトを形成すると突条部の
機械的強度が低下するのは否めない。このため、
上記スリツト巾でできるだけ巾挾に形成して機械
的強度の維持を図らねばならないが、その場合は
逆に毛の補捉性が悪くなる。 By the way, it cannot be denied that when the slits are formed, the mechanical strength of the protruding portion is reduced. For this reason,
It is necessary to maintain mechanical strength by forming the slit as wide as possible, but in this case, the ability to trap hair becomes worse.
この考案は上記突条部に形成したスリツト各間

ることにより、上記欠点を解消したものである。 This invention solves the above-mentioned drawbacks by forming pores large enough to prevent hairs from entering between the slits formed in the protrusions.
以下、この考案の一実施例を図面にしたがつて
説明する。 An embodiment of this invention will be described below with reference to the drawings.

補強板、7は取付用の係止片である。 FIG. 1 shows an outer blade of a reciprocating electric shaver. In the figure, 1 is a rectangular foil-shaped outer blade base formed by electrodeposition, and has a large number of hair introduction holes 2 over almost the entire area. Reference numerals 3 and 3 denote protrusions located at both ends of the outer cutter base 1 in the width direction and integrally formed along the longitudinal direction. This was done to raise the hair. Reference numeral 4 denotes a number of slits formed to intersect with the protrusion 3, and a number of pores 5 are formed between the slits 4 as shown in FIG. The pores 5 are formed to a size (40 microns or less) that does not allow hair to enter. 6, 6 are reinforcing plates, and 7 is a locking piece for attachment.
上記外刃の電着工程を説明すればつぎのとうり
である。 The electrodeposition process for the outer cutter will be explained as follows.
まず、第3図に示すように導電性マスタ10の

上に形成する、この第2次電着層14第7図のよ
うに第1次電着層13から剥離することにより、
第1次電着層13に対応する部分がいわゆるカウ
ンタシンク部として凹入された外刃が得られる。 First, as shown in FIG. 3, an electrically insulating thin film 11 corresponding to the hair introduction holes 2 and pores 5 is formed on the main body of the conductive master 10. , 12 are formed by pressing on both ends of the master 10 as shown in FIG. Thereafter, the master 10 is immersed in an electrodeposition layer (not shown) to perform primary electrodeposition, and the master 10 is
As shown in FIG. 5, a primary electrodeposited layer 13 is formed on the main surface side of the substrate, protruding beyond the thickness of the thin film 11. Next, the second electrodeposited layer 14 constituting the outer blade base 1 is coated with the first electrodeposited layer 13 as shown in FIG. 6 in the same manner as described above.
By peeling off the secondary electrodeposited layer 14 formed thereon from the primary electrodeposition layer 13 as shown in FIG.
An outer cutter is obtained in which a portion corresponding to the primary electrodeposited layer 13 is recessed as a so-called countersink portion.
すなわち、上記突条部3,3にスリツト4を形
成した外刃において、スリツト4各間の部位に多
数の細孔5を形成してあるから、上記突条部3,
3の部分は、断面アーチ形部分が連続することに
なり、断面2次モーメントが大となり、スリツト
幅を狭くしなくても上記突条部3,3の強度を高
められる。 That is, in the outer cutter in which the slits 4 are formed in the protrusions 3, 3, a large number of pores 5 are formed between the slits 4.
In the portion 3, the cross-sectional arch-shaped portion is continuous, and the moment of inertia of the cross-section is large, so that the strength of the protrusions 3, 3 can be increased without narrowing the slit width.
しかも、この外刃は突条部3,3で伏臥してい
るくせ毛や長毛を起毛させるものであるが、スリ
ツト4各間に多数の毛の入らない程度の細孔5を
設けることにより、上記突条部3,3の裏面が徴
細な凹凸状面となり、使用時に肌に当てて滑らせ

層しごき、くせ毛や長毛を根本から起立させるこ
とができる。 Moreover, this outer cutter is used to raise curly hair and long hair that lie down on the protrusions 3, 3, and by providing pores 5 between each of the slits 4 that are large enough to prevent hair from entering, the above-mentioned The back surfaces of the protrusions 3, 3 have a finely uneven surface, and when the skin is slid against the skin during use, the skin digs into these fine rough surfaces, causing the protrusions 3, 3 to become uneven. In addition to the hair raising effect, it can further tighten the skin and make curly and long hair stand up from the root.
このように突条部3,3の毛の入らない程度の
細孔5は、突条部3,3の機械的強度を向上させ
るでけでなく、細孔5による突条部3,3の表面
粗さにより、突条部3,3の起毛という本来機能
を助長することができる。 In this way, the pores 5 of the protrusions 3, 3, which are small enough to prevent hair from entering, not only improve the mechanical strength of the protrusions 3, 3, but also improve the mechanical strength of the protrusions 3, 3 due to the pores 5. The surface roughness can promote the original function of raising the protrusions 3, 3.
ところで、上記実施例では突条部3,3を矩形

ど、突条部にスリツトを形成した外刃にはすべて
適用できるものである。 By the way, in the above embodiment, the protrusions 3, 3 are formed along the longitudinal direction of the rectangular foil-like substrate 1, but the extending direction of the protrusions 3, 3 is different from the above example. This is not limited to, and is not limited to the outer blades of reciprocating electric shavers, but also outer blades with slits formed in the ridges, such as the outer blades of rotary electric shavers and the outer blades of rotary electric shavers. All are applicable.

せることができる。 As described above, in this invention, slits are formed in the raised protrusions of the outer blade base composed of the final electrodeposited layer, and pores are formed between each slit. It is possible to improve the reinforcing effect of the part.
