Description

[Detailed Description of the Invention] (Technical Field) This invention relates to a razor blade case, and particularly to a case for a cartridge type razor blade.

(Prior art) Conventionally, cartridge-type razor blades (hereinafter abbreviated as spare blades) are stored in a spare blade case as a set, and are sequentially attached to the tip of the razor handle and disposed of after being used several times. Generally, this is done. In this case, in order to ensure safety, troublesome management is required, such as removing the replaceable blade in use and returning it to the replaceable blade case, or providing a separate safety cover and attaching it to the replaceable blade attached to the handle.

Further, since the number of replaceable blades that can be stored in the replaceable blade case is limited, there is a problem in that the number of replaceable blades that can be stored in the case must be bought and sold as a unit.

(Purpose of the Invention) In consideration of the above circumstances, the object of this invention is to provide a replacement blade case which can be used as a safety cover without the need for a special safety cover, and which can store as many blades as needed or can be bought and sold.

(Example) An example of this invention will be described below with reference to the drawings.

1 to 3, a replaceable blade case 1 is an injection molded resin product having a substantially rectangular parallelepiped shape, and has an accommodation recess 3 in which one replaceable blade 2 can be stored at once. Inside this storage recess 3, on both sides in the width direction, oblique replacement blade receiving surfaces 4 are provided from the bottom surface to the front wall (downward in FIG. 1), and at the upper center of the front wall, a replacement blade with a triangular cross section is provided. A fixed block 5 is provided. However, the receiving recess 3, the receiving surface 4 and the fixing block 5 are not relevant to the gist of the present invention.

Both ends of the front wall of the replaceable blade case 1, except for the bottom, extend by a certain width to form a pair of protrusions 6 as engaging protrusions. Further, a spacer 8 is provided on the outer side of the upper center of the front wall with a certain length and protrudes further forward.

The amount of protrusion of the spacer 8 is set to a height such that when the replaceable blade cases 1 are combined, the spacer 8 comes into close contact with the rear wall of the adjacent replaceable blade cases 1, as will be described later.

On the other hand, both end portions of the rear wall of the replaceable blade case 1 extend rearward over the entire height, and engagement recesses into which the projections 6, 6 can be fitted are provided at opposing positions on the inside of the base. A pair of grooves 8, 8 are machined in the vertical direction. A bottom is provided at the vertical lower end of this groove 8, and the length to this bottom is the protrusion 6.
It is determined according to the vertical length of. Further, a small protrusion 9 is provided protruding near the upper part of the outer center of the rear wall. The height of the small protrusion 9 is approximately the same as the height of the spacer 7, and the upper surface of the small protrusion 9 is determined so as to come into contact with the lower surface of the spacer 7 when the replaceable blade case 1 is assembled.

The replaceable blade case 1 constructed as described above accommodates each replaceable blade 2 in its housing recess 3, and is positioned and fixed therein by the replaceable blade receiving surfaces 4, 4 and the fixing block 5. In this state, as shown in Figure 4, push the tip of the razor handle 10 vertically to remove the blade 2.
is attached to the tip of the handle 10 while being housed in the replaceable blade case 1.

This state is also a state in which a safety cover is attached to the replaceable blade 2 in use. That is, the replaceable blade case 1 also serves as a safety cover for the replaceable blade 2 during use. This has been made possible because the number of replaceable blade cases 1 accommodated is one, and each replaceable blade case 1 can be combined and divided into an appropriate number of pieces as described below. In this combination, as shown in FIG. 3, the second replaceable blade case 1 is assembled from above the rear part of the replaceable blade case 1 so that its projections 6, 6 fit into the grooves 8, 8. The lower end surface of the protruding piece 6 comes into contact with the vertical bottom of the groove 8 and stops, and just at that position, the upper surfaces of the front and rear replaceable blade cases 1, 1 become flush. Also,
In this state, the front end of spacer 7 is attached to the front spare blade case 1.
Since the upper surface of the small protrusion on the rear wall of the front replaceable blade case 1 contacts the outer side of the rear wall and the lower surface of this spacer 7, the front and rear replaceable blade cases 1, 1 can be assembled together without play.

These divisions can be done by hanging nails on spacer 7, or
Alternatively, this can be easily achieved by supporting the front and rear replaceable blade cases 1, 1 with separate fingers, respectively, and applying force to lower the front replaceable blade case 1 relative to the rear.

In this way, when a plurality of spare blade cases 1 are combined, the whole becomes a spare blade case containing a plurality of pieces, and from this plurality of spare blade cases, the spare blade cases 1 are sequentially assembled.
It can be used as a safety case by dividing the case and attaching the handle 10 as described above.

(Effects) As explained above, this invention provides an engaging protrusion at the front of the blade case that houses one blade, and an engagement recess at the rear, allowing the blade case to be assembled and divided. As a result, it can be used as a spare blade case that can store any number of blades, and also as a safety case, so it is safe and easy to use, and there is no need to provide a separate safety case.
