Description of the Related Art As a spare blade for a razor in which the entire length of the blade edge is not exposed and is exposed at regular intervals, conventionally, a large number of holes are formed in a row in a square film of plastic, It was adhered to the blade so that the holes were aligned with the edge of the blade. In other structures, a back metal is attached to the blade, and a large number of comb teeth extending downward from the edge of the back metal are formed so as to reach below the blade edge. The blade edges were exposed at regular intervals by covering. Further, there is also one in which the blade edge is exposed from between the wires arranged at intervals by spirally winding the wire around the blade body.

る。The structure of the conventional replaceable blade for exposing the blade edges at regular intervals is as described above, and when a plastic film is used, this film is attached to the blade body with an adhesive. Since it is attached, the blade body is rusted by the adhesive agent, and the adhesive agent oozes out to the blade edge. Further, in the case of using the back metal, there is a problem that the hair cut between the comb teeth and the blade is caught. Further, in the case of using the wire, there is a problem that the wire wound in a spiral shape at a constant interval is displaced and the blade edge cannot be exposed at a constant interval. SUMMARY OF THE INVENTION The main object of the present invention is to provide a spare blade whose blade edges are exposed at regular intervals and which does not cause the inconvenience of the conventional product as described above.

The blade edges of the blade body are exposed at regular intervals by providing the blade edges with portions that are not covered by the covering portion at regular intervals. Also, almost the entire thin blade is covered by injection molding of synthetic resin.

装着する。The blade body 1 of the spare blade is made of a thin metal, and substantially the entire blade body 1 is covered with a synthetic resin coating portion 3. The blade edge 2 is exposed at regular intervals. A large number of blade edge exposed portions 4 are provided side by side at regular intervals on the covering portion along the line. The blade body 1 is also covered with the covering portion 3 at its upper edge and both end edges, and is slightly engaged.
Both edges are only exposed from the part. The locking recesses 5 and 5 are for locking and fixing the replacement blade to the replacement blade supply container when the replacement blade is stored in the replacement blade supply container. Reference numerals 6 and 6 are locking holes, and depending on the type of the holder, a protrusion for locking the replacement blade is provided on the holder, and this projection has a locking recess 6 of the replacement blade. Lock 6 and attach a spare blade.

ることができる。A method of manufacturing a spare blade covered with a synthetic resin is manufactured by fixing a metal blade 1 in a mold and injecting a synthetic resin. When the metal blade 1 is coated with a synthetic resin by injection molding, the adhesiveness between the metal and the synthetic resin is strong, and it is possible to manufacture a replacement blade in which the coating portion 3 does not easily peel off from the blade 1 without using an adhesive or the like. You can Further, when the blade 1 is almost completely covered with the synthetic resin including the upper edge and both end edges of the blade 1, the conventional film always has a cut line, so that the film is liable to peel off from the portion. . When the blade body 1 is coated by injection molding as in the present invention, no cuts are formed, so that a complete coating state can be obtained by a simple process.

Reference numerals 7 and 7 are steps that extend in the longitudinal direction of both side surfaces of the replacement blade. The reason for providing the steps 7 and 7 on the replacement blade is that the lower edges 9 and 9 of the holder-when the replacement blade is attached. This is for preventing cut hair or whiskers from being caught between the spare blade and the holder-8 by hitting inside the steps 7, 7. Here, in the case of the conventional product, a separate back metal is attached to the blade to provide a step, and a step is provided on the back metal, and a synthetic resin film is used to expose the blade edges at regular intervals. It was wrapped around the edge and glued. Therefore, two parts must be mounted on the blade body, which complicates the manufacturing process. However, in the present invention, the entire blade body is covered with the synthetic resin coating portion 3, and the blade edge is formed on the coating portion 3. Since the exposed portion 3 and the steps 7, 7 for exposing can be provided, the manufacturing can be performed easily and quickly.

替刃を製造できる。If a spare blade whose blade edges are exposed at regular intervals is manufactured by the manufacturing method of the present invention, a complicated process such as bonding using a separate synthetic resin film is required as in the conventional case. Therefore, the spare blade can be manufactured at a lower cost and faster than the conventional one.

Is covered with. Such a spare blade does not have a protrusion for locking the spare blade and can be used for a razor of a type in which the spare blade is inserted from the tip of the holder. However, it goes without saying that a spare blade having the locking holes 6 and 6 as described above can also be used for such a razor.

る。According to the present invention, the blade body 1 is almost entirely covered with the synthetic resin coating 3 except for the blade edges 2 exposed at regular intervals. . And
The upper edge and both end edges of the blade 1 are also almost covered. Therefore, even if the covering portion 3 and the blade body 1 are not adhered, the covering portion 3 is not displaced, and a film is attached to the blade body by an adhesive so as to expose the blade edges at regular intervals as in the conventional case. Since it does not, the blade body does not rust or the adhesive does not exude to the edge of the blade. Further, since the covering portion 3 covers the blade body 1 in a close contact state, there is no fear that cut hair or whiskers will be clogged between the covering portion 3 and the blade body 1. Furthermore, if the coating portion 3 is formed by injection molding according to the present invention, the blade body 1 can be coated with the coating portion 3 in an instant, so that the blade body 1 can be manufactured quickly and easily, and the cost can be reduced. . Conventionally, a step of manufacturing a separate film, a back metal, and a wire and further attaching these members to a blade body is necessary, but in the present invention, a member such as a separate film is manufactured. Since there are no steps, it can be manufactured quickly and easily. In addition, when the covering portion 3 is formed by injection molding, the covering portion 3 and the blade 1 can be formed without using an adhesive.
Since there is a very small possibility that they will come into close contact with each other and peel off from each other, according to the manufacturing method of the present invention, the blade edge is exposed over the entire length or almost the entire blade is covered with the covering portion, but the upper edge and both end edges are exposed. Needless to say, the present invention can also be applied when manufacturing a spare blade. Further, as described above, when manufacturing a spare blade having the blade edges 2 exposed from the exposed portion 3 at regular intervals and having steps 7 and 7, two parts, a back metal and a film, are conventionally required. It can be manufactured easily and quickly.
