Description

[Detailed Description of the Invention] Technical Field The present invention relates to a replaceable blade case for storing razor blades, cutter knife blades, etc.

Prior Art Conventionally, used spare blades were discarded as they were in a waste basket or wrapped in paper or the like, which caused safety problems as they could cause injuries during cleaning. To solve this problem, used blades were sometimes kept inside the case in which new blades were stored, but this was difficult as new blades and used blades would get mixed up and become difficult to distinguish. It was inconvenient. It is also possible to have a separate case for used spare blades, but since they are separate, it would be difficult to manage as the case for new spare blades and the case for used blades would be separated. There was a problem in disposing of used spare blades.

Purpose This invention was made to solve the above problems, and its purpose is to clearly distinguish between new and used blades, and to dispose of used blades safely and efficiently. To provide a replaceable blade case that can be easily managed and can also easily store used replaceable blades.

Structure In order to achieve the above object, the present invention provides a lid of a spare blade case with an unused blade storage section for storing used spare blades and an opening into which the spare blades are inserted, which communicate with each other. A narrow portion is provided in the lid between the unnecessary blade storage portion and the opening, and the width of the opening is made larger than the width of the narrow portion.

Embodiment An embodiment embodying the present invention will be described below with reference to FIGS. is used as a used blade storage section 3 into which a new spare blade 2 is placed. A fitting part 5 is formed in the opening 4 of the main body case 1 via a stepped part 5a, and engagement protrusions 6 are provided on both outer surfaces of the fitting part 5.

Reference numeral 7 denotes a lid of the main body case 1, which is also formed in the shape of a rectangular cylinder with a bottom, and the inside of the cylinder forms an unnecessary blade storage section 9 into which a used replaceable blade 8 is placed. 1
Reference numeral 2 denotes an opening into which the replaceable blade 8 is inserted, which communicates with the unused blade storage section 9, and the lid 7 between the storage section 9 and the opening 12 has the opening shown in FIGS. 5 and 6.
As shown in the figure and FIG. 13, a pair of upper and lower cross sections U
A letter-shaped sealing protrusion 10 is provided to protrude toward the inside of the unnecessary blade storage part 9, and a narrow part 11 is formed between the tip ends of both protrusions. And the width W of the narrow portion 11
The width W2 of the opening 12 is formed larger than that of the opening 12. Therefore, the used replaceable blade 8 has a width W2 larger than the width W1 of the narrow portion 11.
Since it is first guided by the guide and then inserted into the narrowed part 11, it is very easy to insert it. The gap formed by both sealing protrusions 10 is approximately the same as the thickness of the blade of the replaceable blade, or is formed somewhat narrower, but since the sealing protrusion 10 acts elastically, the unnecessary blade storage section It is easy to insert a used blade into the blade 9, and once inserted, the replacement blade does not come out easily. Moreover, the lid body 7
A fitting part 13 is provided in the opening 12, and the fitting part 5 of the case body 1 is fitted along the inner surface of the fitting part 13. Furthermore, engagement recesses 14 are provided on both inner surfaces of the fitting part 13 and engage with the engagement protrusions 6 formed on the fitting part 5, and the lid body 7 is removably fitted into the main body case 1. It is becoming more and more common.

In the replaceable blade case configured as described above, a new replaceable blade 2 is housed in the main body case 1 as shown in FIG. 4, and when the replaceable blade 2 is fitted with the lid 7,
The new replaceable blade 2 is sealed by a sealing protrusion 10 formed in the blade. On the other hand, the used blade 8 is first guided through the opening 12 and then inserted into the unnecessary blade storage part 9 through the narrowed part 11. Blade 8 never comes out again. Therefore, in this spare blade case, the lid body 7 has an unnecessary blade storage section 9.
Since this is provided, the used spare blade 8 can be easily managed, and the used spare blade 8 can be disposed of safely.

Note that this invention is not limited to the above-mentioned embodiments, but can also be implemented in the following manner.

(a) As shown in FIG. 14, the cross-sectional shape of the sealing protrusion 10 may be provided with an obtuse guide on the opening side. In this way, the used blade 8 can be easily inserted into the unnecessary blade storage section 9.

(b) The sealing protrusion 10 may have a rectangular cross-sectional shape as shown in FIG. 15, or may be formed protruding back and forth in the longitudinal direction of the unnecessary blade storage portion 9 as shown in FIG. good. In this way, the used blade 8 that has once entered the unnecessary blade storage section 9 becomes more difficult to come out.

(c) As shown in Figures 17 and 18, the sealing protrusion 1
0 can be implemented with the shape viewed from the opening 12 obliquely, or it may be implemented in combination with the embodiments (a) and (b) above. As a result, the narrow portion 11 formed by the sealing protrusion 10 can have a width in terms of dimensional accuracy, and the same effect as the embodiment (b) above can be obtained.

(d) As shown in FIG. 19, the narrow portion 11 may be formed by the sealing protrusion 10 on either the upper or lower side.

Effects As detailed above, this invention has an unnecessary blade storage section on the lid of the spare blade case to store used spare blades,
An opening into which the replacement blade is inserted is provided in communication with each other, and a narrow part is provided in the lid body between the unnecessary blade storage part and the opening, and the width of the opening is wider than the width of the narrow part. By increasing the size, it is not only easier to insert used blades into narrow spaces, but also easier to manage used blades. Since they never come out, used blades can be disposed of safely and easily, making it an excellent practical idea as a spare blade case.
