Description

[Detailed description of the invention] This invention relates to a portable, easy-to-assemble razor that can be folded compactly when not in use, is easy to assemble when in use, and also prevents deep shaving and eliminates shaving debris. It is an object of the present invention to provide a new portable and convenient razor that has functions that can be eliminated suitably and is inexpensive to manufacture.

An embodiment of this invention will be described below with reference to the drawings.

The portable and convenient razor of this invention has a razor blade integrally attached to a flat plate made of materials such as paper or synthetic resin, and has a compact shape that is easy to assemble when in use and easy to carry when not in use. It is constructed to be foldable, and in FIG. 1, reference numeral 1 indicates a generally rectangular flat plate. A folding line 2 is formed over the entire length of the flat plate 1 in the transverse direction, and two folding lines 3 are formed in the vertical direction from one side edge to the other side edge (in the figure). (Rightward) It is formed in a shape that widens toward the end, and further, cutting lines 4, 4 are cut into the ends of these assembly fold lines 3, 3 in a shape that similarly widens toward the end and has a circular arc shape. These cut lines 4, 4 extend outward of the flat plate 1, and mounting grooves 6,
6, the holder support pieces 5, 5 are formed.

On the inner flat plate 1 sandwiched between the cut lines 4, 4, a crease line 7 for preventing deep scratches is formed in the lateral direction, and protrusions 9 for preventing deep scratches are connected on both sides in the direction of the side edges. A blade holder 10 with a through hole 8 formed between the anti-scabbing protrusions 9 and 9 is attached to the flat plate 1.
It is formed on the side edge of. The blade holder 10 bends the flat plate 1 at the side edge and places the blade 11 on the inside of the flat plate 1.
The tip of the blade 11 is exposed in the through hole 8, and the blade holder 10 is bonded to the blade holder 10.
The tip is exposed over its entire length.

In addition, each of the above-mentioned folding lines 2, assembly folding lines 3, and deep scratch prevention folding lines 7 may be made into a thin wall shape depending on the material of the flat plate 1, or may be made into a groove shape as in the embodiment shown in the figure, or as appropriate. Appropriate measures can be taken. In FIG. 1, the folding line 2 for folding and the folding line 3 for assembly are each formed in a mountain fold, and the folding line 7 for preventing deep scratching is formed in a valley fold.

Further, on the opposite side edge of the blade holder 10, knob section cutting lines 13, 14 are formed outwardly from the assembly fold lines 3, 3, with one side being linear and the other side being arcuate.

When the portable and convenient razor according to the invention constructed as described above is not in use, as shown in Fig. 3,
The flat plate 1 in the unfolded state shown in FIG. 1 is folded from the folding line 2 into a mountain fold so as to sandwich the blade holder 10. In this folded state, it is also possible to use the flat plate 1 for folding and advertising with the advertisement display printed in advance on the front side. Next, when using the assembly folding lines 3, 3
The folding line 7 for preventing deep scratching is further folded in a valley to form the grip part 12 as shown in FIG. Hold the holder 10 in your mouth to assemble it, insert the tongue piece 15 formed by the arcuate cut line 14 into the linear cut line 13 of the grip part 12, engage it, pinch the grip part 12, and use it in the same way as a normal razor. do. At this time, as shown in FIGS. 4 and 5, the anti-scorching protrusions 9, 9 protrude from both ends of the blade piece 11 to prevent deep scuffing, and
It acts to prevent the blade piece 11 from sliding sideways,
In addition, the through hole 8 expels scraps to the outside, and the both inner ends of the through hole 8 come into contact with the skin to keep the moving direction of the cutting edge constant.
Combined with this action, it prevents skidding and increases safety. Also, when using the assembly, the blade piece 11 is glued,
The internal blade holder 10 is fitted into the mounting grooves 6, 6 formed in the holder support pieces 5, 5, and serves as a beam connecting the left and right holder support pieces 5, 5 and the knob portion 12 connected thereto. Fulfill. Furthermore, a pair of mountain-folded assembly fold lines 3, 3 connects the knob part 1.
2 is formed in a U-shape that opens downward with the back part 9' in between, so that the grip part 12 does not bend even if the cutting edge of the blade piece 11 receives a reaction force from the skin. In addition, since the parts of the assembly fold lines 3, 3 connected to the cutting lines 4, 4 are formed in a curved manner, an appropriate elastic stress is applied during assembly, further strengthening the solidity of the structure, and the blade piece 11 is It makes contact with the skin elastic, improves the feeling of use, and enhances the functionality of the razor. Therefore, the overall structure is strong and has a shell structure, and can withstand use even when relatively thin materials such as paper and synthetic resin are used.

As explained above, the portable, lightweight razor of this invention is constructed by simply attaching razor blades to a flat plate made of paper, synthetic resin, or other material, and forming fold and cut lines at appropriate locations. This makes it easy and inexpensive to manufacture, and it can be folded up compactly when not in use.
It is easy to assemble when in use, and the handle is constructed in a U-shape with the blade holder as a beam and the blade tip side open, so the blade tip will not bend even if force is applied. The deep-warping prevention protrusion prevents deep warping and lateral slippage, improving safety, and increasing the stability of the blade for a comfortable feel. The through hole in the deep-warping prevention protrusion removes shavings, and this through hole also serves as a guide groove for the blade when it travels, further increasing the stability of the razor and making it easier to use.
