Description

[Detailed description of the invention] The invention is a razor in which a piece of cardboard with a symmetrical shape is folded around the folding line, and the blade is sandwiched between the folds, and the blade is reliably protected until use. This invention relates to a simple razor designed to be safe and used, for example, for women's preparation before applying makeup.

The present invention will be described in detail below according to embodiments shown in the drawings.

FIG. 1 is a perspective view of a piece of cardboard 2 having a symmetrical shape around a folding line 1 used in the present invention.

A double-sided adhesive sheet 3 is placed on top of the cardboard 2, and on one side of the folding line there is a notch 5 for exposing the cutting edge 4, and on the other side there is a perforation 7 at a symmetrical position corresponding to the notch line 6 of the notch. is provided.

However, in order to prepare the cardboard 2 as shown in Fig. 1,
First, a double-sided adhesive sheet 3 having a release paper (not shown) on one side is adhered to a piece of cardboard 2, and in this state, the outline, notch line 6, perforation line 7, folding line 1 as shown in FIG.
The punching process can be carried out using a Thomson die having the following properties.

After that, remove the release paper and place the blade 8 in a predetermined position so that the blade edge is exposed in the notch for exposing the blade as shown in Figure 2. to hold.

In this case, as shown in FIG. 3, the tip portion 9 of the perforation 7 covers the cutting edge 4 and extends further forward, so this tip portion 9 becomes a protection portion for the cutting edge.

Then, when in use, by cutting off the tip portion 9 along the perforation 7, the cutting edge 4 is exposed and can be used as a razor.

Figures 4 to 6 show another embodiment of the present invention, in which the notch line 6 and perforation line 7 are provided near the center of the cardboard at symmetrical positions across the folding line 1. ing.

In this case, the cutout line may be extended to the 10 perforations shown in FIG. 4. If this is done, it will be easier to separate the tip portion 9 during use.

In addition, in the case of this embodiment shown in Figs. 4 to 6, the mounting position of the cutting edge 4 coincides with the crease line 1 compared to the previous embodiment shown in Figs. This has the advantage that if the length Y of the blade 8 is configured to be longer than the width X of the notch 5, there is no danger that the blade 8 will jump out from between the sandwiched cardboard 2. .

Another embodiment is shown in FIGS. 7-9.

In this case, the cardboard 2 is formed with a handle portion 11 so that it can be easily held when using the razor.

In addition, the blade 8 shown in Figures 8 and 9 has an aluminum foil guard 1 on the cutting edge 4.
2 is provided, so there is little chance of direct skin damage, and it is designed to be safe even if parents and children use it accidentally.

FIG. 9 shows a plan view with the blade edge protector removed.

As explained above with reference to the three embodiments, the present invention is a razor in which a piece of cardboard having a substantially symmetrical shape is folded around the folding line 1, and the blade 8 is held between the two. A notch 5 for exposing the cutting edge 4 is provided on one side, and a perforation 7 is provided on the other side at a symmetrical position corresponding to the notch line 6 of the notch 5. Since the cutting edge protector is configured to be separable when used, the cutting edge 4 can be reliably protected until it is used.

Therefore, it has the advantage that it can be easily packaged at the time of sale, and since it is safe to carry, it can be easily carried in a handbag or the like.

Furthermore, since the entire structure is made of cardboard and can be easily manufactured by Thomson processing, it can be produced at low cost and in large quantities, and can also be used as a disposable razor. It can be used in a wide range of fields, including as a razor for opening plastic bags.
