A safety razor in which the blade covers the blade edge of the blade body overlaid and the blade edge of the blade body is exposed from between the respective blade guards is described in Japanese Utility Model Laid-Open No. 4-112377. As is apparent from the drawings of this publication, this is a safety razor in which a plurality of blades are superimposed, and the blade guard is not wound around the blade for each blade, but the blade guard is composed of a plurality of blades. It is wrapped around the blade of the body to cover it.

[0004]

The conventional multi-blade safety razor having a whisker debris discharge mechanism has the above-mentioned structure, and the whisker debris discharge part is moved forward to be jammed between the blade bodies. The safety razor for ejecting the whisker debris does not have a cutting edge guard, and a large number of thin cutting edges extending substantially perpendicular to the cutting edge of the cutting blade are provided on the razor. The safety razor, which covers the cutting edge and exposes the cutting edge of the cutting body from between the respective cutting edge guards, has no mechanism for removing the mustache.

If a cutting edge guard is mounted on the cutting edge of the blade of a safety razor equipped with such a shavings discharging mechanism, the front edge of the shavings discharging portion moved forward to push out the shavings will have a cutting edge. You can't go any further after hitting the guard. As a result, the mustache clogged between the blades cannot be completely discharged to the outside, and the mustache remains between the blades.

In view of the above, the present invention provides a blade tip with a blade tip
It is an object of the present invention to provide a safety razor which is equipped with a discharge mechanism for attaching and removing a mustache and capable of completely removing a mustache.

The present invention is not limited to one having three blades,
The blade may have two blades, or if possible, may have four or more blades.

The spacers 6 and 7 are integrally molded of synthetic resin and include spacer main bodies 29 and 30, flexible connecting portions 8 and 9 and mustard discharging portions 10 and 11. The spacer bodies 29 and 30 are for keeping the interval between the two blades constant, and also have the function of discharging the whiskers clogged between the blades in cooperation with the other parts. Eggplant Spacer body 2
9 and 30 are each formed in two parts, and the flexible connecting parts 8,
9 are formed integrally. The flexible connecting portions 8 and 9 are integrally connected at the central portion to beard scum discharging portions 10 and 11 extending in the lateral direction at intervals in front of the spacers 6 and 7. . Flexible connecting parts 8 and 9 and mustard discharging part 1
The thicknesses 0 and 11 are formed thinner than the thicknesses of the spacers 6 and 7. Therefore, the flexible connecting portions 8, 9 and the shavings discharging portions 10, 11 are movable between the blade bodies.

The width in the front-rear direction of the spacer body 29 of the lower spacer 6 is formed longer than the width of the spacer body 30 of the upper spacer 7. Therefore, the leading edge of the lower spacer mustache discharge section 10 is located ahead of the front edge of the upper spacer mustard discharge section 11 by this width difference. This is mounted so that the blade edge of the middle blade body 4 is retracted from the blade edge of the lower blade body 3, and the blade edge of the upper blade body 5 is further retracted than the blade edge of the middle blade body 4. It depends.

The whisker discharge portions 10 and 11 are supported at their central portions by the flexible connecting portions 8 and 9, and both ends of the whisker discharge portions 10 and 11 are formed at free ends. Also, both side portions 31, 32 of the spacer body extend forward so as to cover both end portions of the mustard discharge portions 10, 11.

A large number of recesses 23 and 24 are provided at the front edges of the mustard discharge portions 10 and 11, respectively. Recess 2
The number of 3, 24 is not limited to a large number, and may be about 4 to 5. The number of the recesses 23 and 24 of the lower spacer 6 and the upper spacer 7 are the same, and the positions where they are provided also match. This is because, as described later, since the leading edges of the swarf discharge portions 10 and 11 abut against the blade edge guard and cannot be further advanced, the swarf is provided by providing a concave portion in accordance with the position of the blade edge guard. Discharge unit 10,

15 are provided and they are fitted to each other, so that the finger pads 12 and 13 move integrally. A step 36 is formed at the boundary between the slide portion 33 of the lower spacer and the finger rest portion 12. The height of the step 36 is slightly larger than half the thickness of the middle blade 4. A similar step is shown in the upper spacer.
Is formed also at the boundary between the slide portion 34 and the finger rest 13. The reason for providing these steps is to provide a gap so that both finger rests 12 and 13 can move back and forth. The finger rests 12 and 13 are provided at the center of the flexible connecting parts 8 and 9 extending in the lateral direction at the rear of the spacer through the sliding parts 33 and 34 for the blade base 1 and the top plate 2. It is provided so as to project rearward. The slide portions 33 and 34 are inserted into insertion holes 35 provided at the center of the rear portions of the blade base 1 and the top plate 2 and can slide in the front-rear direction. As a result, when the finger rests 12 and 13 are pushed forward, the flexible connecting parts 8 and 9 bend and the shavings discharging parts 10 and 11 move forward to remove the shavings clogged between the blades. Push forward to drain out and rinse with water.

The guard plate 25 extends from the back surface of the lower blade body 3 to the upper surface of the upper blade body 5, as shown in FIG.
It is attached so that it winds around the cutting edge. The edge guard of the present invention does not cover the edge with a different edge guard for each edge of each blade, but the edge guard collects the edges of the stacked blades as shown in FIG. Covered. By providing a large number of window holes 27 in a portion of the guard plate 25 wound around the blade body covering the blade edge, the blade edge of the blade body is exposed from the window holes 27. Since the window holes 27 are provided very close to each other, a large number of thin blade guards 28 are formed between the window holes 27 to cover the blades at equal intervals. The number of the blade guards 28 is the same as the number of the concave portions 23 and 24 provided in the mustard discharge portion, and the provided positions also match. This is, as described above, a mustard discharge unit 10,
Since the leading edge of the blade 11 cannot contact the blade guard and can be advanced further, the recesses 23 and 24 are provided in accordance with the position of the blade guard 28 so that the blade guard 28 can be moved.
Are discharged into the recesses 23 and 24 to remove mustaches.
This is in order to make 1 advance further.

Although the guard plate 25 is formed of a thin metal plate, it is a matter of course that it may be formed of a synthetic resin. Further, the configuration for covering the blade edges of the blade at equal intervals is not limited to a configuration in which a guard plate is wound, and a configuration in which a thin wire is wound around the blade at equal intervals may be used. In addition, as shown in the drawing, the structure for moving the mustache discharging portions 10 and 11 forward includes the spacer main bodies 29 and 30 and the flexible connecting portions 8 and 9 and the mustard discharging portions 10 and 11. It is not limited to the one formed integrally with the spacers 6 and 7, but the mustard discharge portions 10 and 11 extending in the lateral direction at an interval in front of the spacer and removing the mustache. Any configuration is possible as long as it moves forward to discharge.
