[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage container for cutting tools, and more particularly, an opening or division operation for each storage unit can be easily performed by appropriately connecting the storage units for storing cutting tools. The present invention relates to a storage container for cutting tools.

[0002]

2. Description of the Related Art Conventionally, a cutting tool such as a drill or a milling tool is generally stored separately in a single cutting tool storage container, and is generally transported and stored in such a state. there were. This is to prevent an operator from being injured by a sharp cutting edge and prevent damage to the cutting edge due to contact between tools.

Here, a conventional container 100 for cutting tools is used.
Will be described. The cutting tool storage container 100 is shown in FIG.
As shown in (1), the main body 100a and the lid 100b are formed in a substantially hollow cylindrical shape. The main body 100a is a lid 1.
Since it is formed in a size smaller than 00b,
The cutting tool storage container 100 can be closed by fitting the lid body 100b to the main body 100, and as a result, the drill 101 is inserted in the cutting tool storage container 100.
Can be stored.

As a method for identifying the cutting tool storage container 100, as shown in FIG. 9, the label 10 on which the specifications (identification information) of the stored drill 101 are printed.
The method of sticking 2 to the storage container 100 for cutting tools is generally used. This label 102 has a drill 101
The tool specifications such as the material, size, and manufacturing number, the manufacturer name, and the like are printed by various printing techniques, and they are attached to the cutting tool storage container 100 by the adhesive layer formed on the back surface. For example, in a tool maker, this label 10
By recognizing the print contents of No. 2, inventory management, shipping management, etc. are performed, and sales management etc. are performed in the store.

[0005]

However, in the above-mentioned cutting tool storage container 100, a plurality of cutting tools cannot be stored at one time, and therefore each cutting tool (cutting tool storage container) is in a disjointed state. There is a problem that it is inefficient because it needs to be transported and stored.

Therefore, as a result of diligent study on this problem, the present inventor has found that a plurality of cutting tools can be efficiently stored by using the following storage container for cutting tools. That is, the cutting tool storage container includes a plurality of independent storage portions, and adjacent ones of the plurality of storage portions are connected to each other by a connecting member. According to this storage container for cutting tools, a plurality of cutting tools can be stored at the same time, and each cutting tool can be stored individually. Further, by cutting the connecting portion, each cutting tool (storage portion) can be separated and divided.

However, in this cutting tool storage container, it has been found that there is a problem that it is difficult to open only one storage part because each storage part is connected by the connecting member. That is, even in the operation of expecting to open only one storage part, another storage part adjacent to the storage part will be opened by interlocking via the connecting member.

The present invention has been made in order to solve the above-mentioned problems, and makes it possible to perform an unsealing operation for each storage part by making the connection state between the storage parts for storing a cutting tool proper. It is intended to provide a storage container for tools.

[0013]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a top view of a cutting tool storage container 1 according to a first embodiment of the present invention. First, referring to FIG. 1, a cutting tool storage container 1
The general configuration of will be described.

The storage container 1 for cutting tools is a container used for the purpose of transporting and storing cutting tools (not shown), and is formed in a substantially box shape using a resin material. First
The cutting tool storage container 1 in the embodiment includes five storage parts 1a to 1e, and one storage device can be stored in each of the storage parts 1a to 1e, and a total of five cutting tools can be stored individually. Is configured. Examples of the cutting tool include a drill, a bite, a milling cutter, an end mill, a reamer, a tap, and a tip.

The accommodating portions 1a to 1e are integrally formed by mutually adjoining ones being connected to each other by the container connecting member 3 and the lid connecting member 5. Therefore, this storage container 1 for cutting tools can store 5 cutting tools collectively by one storage container 1 for cutting tools by using each storage part 1a-1e.

Further, in the cutting tool storage container 1, the storage parts 1a to 1e can be separated and divided by cutting the container connecting member 3 and the lid connecting member 5, respectively. Each of the storage spaces 1a to 1e can be separately transported and stored while being stored. Furthermore, when only the lid connecting member 5 is cut,
With the storage spaces 1a to 1e still connected, only the required lid member 4 can be opened, and any of the five stored cutting tools can be taken out.

On the upper surface (front side of FIG. 1) of the cutting tool storage container 1 (lid member 4), identification information 11 is stored in each storage unit 1.
It is displayed every a to 1e. The identification information 11 is for identifying and managing the cutting tool storage container 1, and is directly written on the outer surface of the cutting tool storage container 1 by irradiation of laser light.

Next, with reference to FIGS. 1 to 3, a detailed configuration of the cutting tool container 1 will be described. 2 is a side view of the cutting tool storage container 1 as seen from the direction of arrow II in FIG. 1, (a) shows a state in which the lid member 4 is closed, and (b) shows It shows a state in which the lid member 4 is opened. 3 is a cross-sectional view of the cutting tool storage container 1 taken along the line III-III in FIG.

As shown in FIGS. 1 to 3, the storage container 1 for cutting tools has five storage portions 1a formed in a substantially rectangular parallelepiped shape.
1e are connected and mainly composed of the container member 2,
The container connecting member 3, the lid member 4, the lid connecting member 5 and the like are provided. The first embodiment will be described using the drill 6 as the cutting tool to be stored.

The container member 2 is formed of a resin material such as polypropylene (PP) into a substantially hollow box-shaped body, and the upper portion (upper side of FIGS. 2 and 3) of the container member 2 accommodates the drill 6 therein. It is open to you. Storage container for cutting tools 1
, Five container members 2 are arranged at substantially equal intervals while pointing in the same direction, and these adjacent container members 2 are
As shown in FIG. 1 or 3, they are connected to each other by a container connecting member 3 and are integrally formed. Therefore, by cutting the container connecting member 3, each container member 2 can be separated and divided.

As described above, the container connecting member 3 is a member for connecting and integrating the container members 2 with each other.
As shown in FIG. 2, the container members 2 are connected at two end portions in the longitudinal direction (vertical direction in FIG. 1) of the storage units 1a to 1e (container member 2). Further, the container connecting member 3 is
As shown in FIG. 1, it is formed to have a narrow width in a top view and its rigidity is reduced.

The lid member 4 is a member which is provided on the open portion of the container member 2 and covers the drill 6 together with the container member 2. This lid member 4 is made of polypropylene (P
It is formed of a resin material such as P) into a substantially thin plate shape, and is formed separately from the container member 2 described above (see FIG. 5).
The identification information 11 described above is written on the upper surface side (upper side of FIGS. 2 and 3) of the lid member 4.

The cutting tool storage container 1 is provided with five lid members 4 corresponding to the container member 2 at substantially equal intervals, and these adjacent lid members 4 are arranged as shown in FIG. Figure 3
As shown in FIG. 5, they are connected to each other by the lid connecting member 5 and are integrally formed. Therefore, by cutting the lid connecting member 5, the respective lid members 4 can be separated and divided.

The lid connecting member 5 is a member for connecting and integrating the lid members 4 as described above.
As shown in FIG. 2, the respective lid body members 4 are connected at two end portions in the longitudinal direction (vertical direction in FIG. 1) of the respective lid body members 4. Further, the lid connecting member 5 is formed to have a narrow width in a top view (see FIG. 1) like the container connecting member 3 and has a low rigidity.

Further, as shown in FIG. 3, the lid connecting member 5 is provided with a notch which is recessed in a groove shape (notched), and a portion where the notch is formed ( The rigidity of the recessed portion) is made smaller than the rigidity of other portions (see FIG. 6B). Therefore, the lid connecting member 5 can be easily cut by cutting the portion where the notch is formed.

The notch of the lid connecting member 5 is
As will be described later, it is formed by irradiating laser light. Therefore, the forming step of irradiating the lid connecting member 5 with the laser beam to form the cutout can be performed in the same step as the writing step of irradiating the laser beam to write the identification information 11. That is, while the identification information 11 is written on the upper surface of the lid member 4 by the laser light emitted from the laser marking device,
The laser beam can be used to form a notch in the lid connecting member 5. Therefore, since a series of steps can be continuously performed, the process cost can be reduced and the work cost of the cutting tool storage container 1 as a whole can be reduced accordingly.

At both ends (left and right sides in FIG. 2) of the lid member 4,
Locking members 8 and 9 are provided, respectively. The locking members 8 and 9 are members for mounting the lid member 4 on the container member 2, and are formed in a shape capable of locking the ends of the container member 2. That is, the locking members 8 and 9 are formed by a known technique in which the end portion of the container member 2 is detachably locked and fixed by utilizing the elastic deformation thereof. Therefore, the lid member 4 is detachably attached to the container member 2 by the action of the locking members 8 and 9.

At the end of the lid member 4 on the side of the locking member 8 (right side in FIG. 2), a handle member 10 is disposed so as to project outward from the end surface (right side in FIG. 2) of the container member 2. Handle member 1
Reference numeral 0 is a portion used when opening the lid member 4. That is, by pushing the handle member 10 upward (upper side in FIG. 2), the locking and fixing by the locking member 9 (left side in FIG. 2) is maintained, but only by the locking member 8 (right side in FIG. 2). 2 can be reliably released, and as a result, as shown in FIG.
As shown in (b), the lid member 4 can be easily opened.

By the way, the adjacent lid members 4 are connected to each other by a lid connecting member 5.
Therefore, when it is desired to simultaneously open all the lid members 4 of the storage units 1a to 1e, only one of the lid members 4 is opened and the other (adjacent ones) connected by the lid connecting members 5 are adjacent to each other. ) Since the lid member 4 can also be opened in conjunction,
As a result, all lid members 4 can be easily opened, which is convenient.

However, when it is desired to open only one lid member 4, the lid connecting member 5 interferes with the opening operation. That is, the adjacent lid body members 4 connected by the lid body connecting member 5 are also opened unnecessarily in conjunction with each other, and only the necessary lid body member 4 cannot be opened.

Therefore, in this case, the corresponding lid body connecting member 5 (for example, when it is desired to open only the lid body member 4 of the storage portion 1a, the lid body connection between the storage portion 1a and the storage portion 1b is performed). The member 5) is cut. As a result, it is possible to prevent the adjacent lid member 4 (lid member 4 of the storage section 1b) from being unnecessarily opened in an interlocking manner, and as a result, only the necessary lid member 4 is easily opened. It is possible.

Particularly, the lid connecting member 5 in the first embodiment.
The groove has a notch that is recessed in the shape of a groove, and the rigidity thereof is reduced. Therefore, the lid connecting member 5 can be easily cut by a general human operation without using a tool such as a nipper. Therefore, it is possible to easily open only the necessary lid member 4 while avoiding a complicated work such as using a special tool.

The lower surface side of the lid member 4 (lower side of FIGS. 2 and 3)
Two brackets 7 are arranged in the. The bracket 7 is a member for holding the drill 6, and is shown in FIG.
As shown in (b), they are arranged so as to face each other with a predetermined space therebetween, and at one end side thereof, as shown in FIG.
An arcuate recess is formed. Therefore, when the drill 6 is stored in the storage container 1 for cutting tools, the drill 6 can be held in the arc-shaped recess of the bracket 7, so that the stored drill 6 can be stably held without rattling. It can be transported (see Figure 3).

When the drill 6 held by the bracket 7 is taken out from the cutting tool storage container 1, as shown in FIG. 4, the container member 2 is held by one hand while the lid member is held by the other hand. The ends of the member 4 and the drill 6 are clamped at the same time.
Then, by bending the lid member 4 held together with the drill 6 so that the bracket 7 side is convex, the gripping of the drill 6 by the bracket 7 is released, as shown in FIG. As a result, it is possible to easily remove the drill 6 from the bracket 7 while avoiding the risk of injury due to the cutting edge of the drill 6.

Details of the identification information 11 written in the cutting tool container 1 will be described below. Identification information 1
1 is composed of character information 11a, symbol information 11b, and barcode information 11c.

The character information 11a is displayed for the purpose of making the person who is visually aware understand it.
It is information represented by letters, numbers, symbols, and the like. For example, type of cutting tool (for example, "drill", "end mill", etc.), material (for example, "high speed steel", "cemented carbide")
Etc.), nominal dimensions (for example, “M10 × 1.5”, etc.), cutting tool specifications, and information such as control number, model number, manufacturer name, and manufacturer number. Similarly, the design information 11b is information represented by a design, a pattern, or the like, and for example, a manufacturer's mark or the like is illustrated.

On the other hand, the bar code information 11c is displayed for the purpose of mechanical processing, and is information represented by a one-dimensional bar code. Therefore, a large amount of information can be efficiently displayed in a limited space, and while the reading device (bar code reader) is used to read with a high false recognition rate, the read information can be processed mechanically at high speed. Therefore, a large amount of information can be processed quickly and accurately.

Further, the bar code information 11c has high security because the information to be displayed can be encrypted. Therefore, even information that could not be displayed by the character information 11a in the related art (for example, secret information unique to the manufacturer) can be displayed after being encrypted.

Examples of the information displayed by the bar code information 11c include information uniquely used by the manufacturer and sales management information used by the dealer. For example, in a store, necessary information is read from the barcode information 11c using a barcode reader at the time of over-the-counter sales and sorting, and the read information is mechanically tabulated,
Can be managed. As a result, it is possible to easily and efficiently perform the identification management of the cutting tool (the cutting tool storage container 1) of which a huge variety exists due to the difference in the nominal size.

The identification information 11 thus constructed is directly written on the outer surface of the cutting tool container 1 by irradiation of laser light (so-called laser marking) as described above. Therefore, it is possible to save the labor of attaching the label, which is required in the conventional container for cutting tools, and it is not necessary to stock and manage the label for attaching. In addition, the label will not be peeled off, and the type of the stored items will not be recognized. Further, according to the laser marking, the identification information 11 can be written at high speed and the identification information 11
You can easily change the content of. Therefore, it is possible to flexibly deal with, for example, a case where a large number of orders suddenly occur while reducing the working cost and running cost.

As the bar code, it is preferable to use a standardized and generally used code from the viewpoint of the cost of the apparatus. For example, JAN (EAN / UP
C) code, ITF code, CODE39, CODAB
AR (NW-7) and the like. However, a unique barcode may be used. Alternatively, a two-dimensional code (two-dimensional symbol code) may be used. For example, a QR code, a PDF417, a Veri code, a maxi code, or the like. By using these, a larger amount of information can be given to the identification information 11 (barcode information 11c).

In addition, in the first embodiment, each of the storage portions 1a-1.
Although the identification information 11 written in e is all the same,
It may be different for each of the storage units 1a to 1e. Further, it is not necessary to write the identification information 11 in all the storage units 1a to 1e, and the identification information 11 may be written only in one or more specific storage units. Alternatively, the identification information 11 may be written in a state of straddling each of the storage units 1a to 1e, that is, on the entire upper surface of the cutting tool storage container 1.

Here, the resin material forming the container member 2 (container connecting member 3) and the lid member 4 (lid connecting member 5) will be described. As a resin material constituting these, in addition to polypropylene (PP), acrylic resin, polycarbonate (PC), polystyrene (PS), polyethylene (PE), polyamide (PA), polyvinyl chloride (PVC), acrylonitrile Butadiene styrene (ABS), epoxy resin (EP), phenol resin (PF), methylpentene polymer, tetrafluoroethylene / perfluoroalkoxyethylene copolymer (P
FA), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyetherimide (PEI), polyetheretherketone (PEE)
K), polyester elastomers, etc. can be used.

The resin material of the container member 2 (and the container connecting member 3) is a transparent or translucent resin material having a light transmitting property so that the presence or absence of the contained cutting tool can be visually recognized. Is preferably selected.

Next, the cutting tool is stored in the storage container 1 for the cutting tool.
A storing step of storing the inside, a writing step of writing the identification information 11 in the storing container 1 for cutting tools, and a forming step of forming a notch in the lid connecting member 5 will be described with reference to FIG. FIG. 5 is a perspective view of the storage container 1 for cutting tools, and is a view showing a process of mounting the lid member 4 on the container member 2. Note that, in FIG. 5, in order to facilitate understanding, the adjacent distance between each container member 2 and the lid member 4 is illustrated as being wider than that in the other drawings.

When the cutting tool (drill 6) is stored in the cutting tool storage container 1, first, as shown in FIG.
The drill 6 is held by the bracket 7 of each lid member 4. After gripping the drill 6, the lid member 4 is attached to the container member 2. That is, the open surface side of the container member 2 faces the bracket 7 side of the lid member 4 (see FIG. 5), and the container member 2 is moved to the lid member 4 side. Lid member 4
The container member 2 abutted on is locked and fixed by the locking members 8 and 9 provided on each lid member 4, and the lid member 4 is mounted on the container member 2. As a result, the five drills 6 are individually gripped by the brackets 7 of the lid member 4 and stored independently in the respective storage units 1a to 1e of the cutting tool storage container 1 (see FIG. 3). ).

As described above, the container member 2 and the lid member 4 are separately configured, and the plurality of container members 2 and the lid member 4 are connected by the container connecting member 3 and the lid connecting member 5. By doing so, the plurality of drills 6 can be stored in the cutting tool storage container 1 by a single operation, and thus the storage process can be efficiently performed.

Incidentally, the lid connecting member 5 in the first embodiment.
The notch is formed in a process after the storing process. Therefore, at the time of this storing step, each lid connecting member 4 has sufficient rigidity. Therefore, each lid member 4
Since they are connected while maintaining sufficient shape retention, they can be conveyed in a stable state without the connecting portion being bent, and work efficiency and work accuracy can be improved.

After the storage step, a so-called laser marking device is used to write the identification information 11 into the cutting tool storage container 1 and the formation step identification information 11 for forming a notch in the lid connecting member 5. And continuously.

Details of the laser marking device used are as follows: laser type: YAG laser, laser wavelength: 1064 nm, laser capacity: 50 W, writing speed:
It is 0.5 mm / s to 200 mm / s. Further, white polypropylene (PP) was used as the resin material of the lid member 4, and a black paint was applied, dried, and baked on the surface thereof.

First, the cutting tool container 1 is installed in the laser marking device. Then, the upper surface of the cutting tool storage container 1 (each lid member 4) is irradiated with laser light. When the lid member 4 is irradiated with the laser light, the paint on the portion irradiated with the laser light is removed. As a result, on the surface of the lid member 4, a contrast between the black portion of the applied paint and the white portion of which the paint has been removed is formed, so that the identification information 11 is written using this contrast. (See Figure 1).

After the identification information 11 is written on the upper surface of the lid member 4, each lid connecting member 5 is irradiated with laser light to form a notch in the lid connecting member 5 (recess). . A forming process for forming the notch will be described with reference to FIG.

6A and 6B are enlarged views of the portion A of FIG. 3, FIG. 6A is a view showing the lid connecting member 5 before irradiation with laser light, and FIG. FIG. 6 is a view showing the lid connecting member 5 in which a notch is formed by irradiation with laser light. The arrow X in FIG. 6A represents the irradiation direction of the laser light.

First, as shown in FIG. 6A, while irradiating the upper surface of the lid connecting member 5 with laser light (arrow X), the laser light is irradiated in the width direction of the lid connecting member 5 (see FIG. a) Move in the direction perpendicular to the paper surface). When the laser light is irradiated for a predetermined time, the irradiation range is melted by the thermal energy of the laser light, and as a result, the lid connecting member 5 is
As shown in FIG. 6 (b), a notch that is recessed in a groove shape is formed (recessed) along the movement path of the laser light.

The groove depth of the notch can be adjusted by the moving speed (irradiation time) of the laser light. In the first embodiment, the moving speed of the laser light was set to 15 mm / s. As a result, the thickness of the lid connecting member 5 is about 65.
The notch can be recessed to a depth of%, and the rigidity of the lid connecting member 5 can be sufficiently reduced.

Here, the irradiation direction of the laser light (arrow X) forming the notch of the lid connecting member 5 is the irradiation direction of the laser light for writing the identification information 11 on the upper surface (upper side of FIG. 6) of the lid member 4. It is in the same direction as. Therefore, after the cutting tool storage container 1 is once installed in the laser marking device, a writing step of writing the identification information 11 is performed while the installation direction of the cutting tool storage container 1 is fixed, and a cutting operation is performed on the lid connecting member. The forming step of forming the notch can be continuously performed. That is, since both of these steps can be continuously performed without changing the installation direction of the cutting tool storage container 1 for each process, the installation work of the cutting tool storage container 1 can be simplified and the work cost can be reduced. Can be reduced.

The notch (recessed portion) of the lid connecting member 5 may be formed (recessed portion) at the stage of injection molding using a molding die. However, the lid connecting member 5 is a portion whose cross-sectional area is very small compared to the lid member 4 (see, for example, FIG. 1). Therefore, if a notch is provided in the lid connecting member 5 from the injection molding stage, the cross-sectional area of that portion is further reduced, and injection molding defects such as insufficient fabric are likely to occur. Therefore, not only the yield in molding deteriorates, but also the management of injection conditions (for example, injection pressure, injection speed, etc.) becomes severe, and the molding cost increases. Therefore, by forming the notch of the lid connecting member 5 by irradiating the laser beam, the notch can be easily and surely formed.

Next, the second embodiment will be described with reference to FIG. Whereas the lid connecting member 5 of the first embodiment is configured to be recessed by the irradiation of the laser light, the cutting tool storage container 21 of the second embodiment has the lid connecting member 25 of the laser light. It is cut by irradiation. The same parts as those in the first embodiment described above are designated by the same reference numerals, and the description thereof will be omitted.

The storing step of storing the cutting tool in the cutting tool storage container 21 (see FIG. 5) and the writing step of writing the identification information 11 in the cutting tool storage container 21 are the same as those in the first embodiment. It is the same. Therefore, here, the cutting step of irradiating the laser beam to cut the lid connecting member 25 will be described with reference to FIG. 7. The detailed specifications of the laser marking device used are the same as those used in the first embodiment.

7A and 7B are enlarged views of the lid connecting member 25, FIG. 7A is a view showing the lid connecting member 25 before laser light irradiation, and FIG. FIG. 6 is a view showing a lid connecting member 25 in which a notch is formed by irradiation with laser light. Note that FIG. 7 corresponds to the portion A of FIG. 3 in the first embodiment, and the arrow X in the drawing indicates the irradiation direction of the laser light.

In the cutting step, after the cutting tool is stored in the cutting tool storage container 21 in the storage step (see FIG. 5), at the same time as the writing step of writing the identification information 11 on the upper surface of the lid member 24 (or, It is performed continuously). Specifically, FIG.
As shown in (a), while irradiating the upper surface of the lid connecting member 25 with laser light (arrow X), the laser light is directed in the width direction of the lid connecting member 25 (direction perpendicular to the paper surface of FIG. 7A). To move. When the laser light is irradiated, the irradiation range is melted by the thermal energy of the laser light, and as a result,
As shown in FIG. 6B, the lid connecting member 25 is cut along the moving path of the laser light.

After cutting the lid connecting member 25, laser light may be further irradiated to form a notch in the container connecting member 23 (concave) as shown in FIG. 6B. Thereby, since the rigidity of the container connecting member 23 can be reduced, the container connecting member 23 can be easily cut, and as a result, the cutting tool storage container 21 is separated into each of the storage parts 1a to 1e. Work can be performed more easily.

In the second embodiment, the lid connecting member 25
The moving speed of the laser light applied to the substrate was set to 5 mm / s.
The moving speed of this laser light is set to the value of the first embodiment (15 mm /
By making the speed lower than in (s), the lid connecting member 2
It is possible to prolong the time for irradiating 5 with the laser light, and as a result, it is possible to cut the lid connecting member 25.

As described above, in the cutting tool storage container 21 according to the second embodiment, the lid connecting member 25 is cut in advance, and therefore, when the lid member 4 is unsealed, as in the first embodiment. It is not necessary to cut the lid connecting member 25. Therefore, while omitting the trouble of cutting the lid connecting member 25,
Only the necessary lid member 4 can be easily opened.

Further, the cutting of the lid connecting member 25 is performed by irradiating the laser beam, and therefore the cutting is performed by assembling the lid member 24 and the container member 25 in the storing step (see FIG. 5) described above. It can be easily performed even after the operation. In other words, since the storage step can be performed in a state where the lid members 24 are connected, the storage step can be efficiently performed.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments.
It can be easily inferred that various improvements and modifications can be made without departing from the spirit of the present invention.

For example, in this embodiment, five storage parts 1a are provided.
Although the storage container 1 for cutting tools including 1 to 1e has been described as an example, the number of storage portions may be 4 or less, or 6 or more. However, the number of such storage units is preferably a multiple of 5, that is, 5, 10, 15, ..., Considering convenience such as management of the number of cutting tools to be stored, and more preferably, It is a multiple of 10. Although the container members 2 and 22 and the lid members 4 and 24 are formed separately, they may be formed integrally.

In this embodiment, the case where one cutting tool is stored in each of the storage units 1a to 1e has been described, but the present invention is not limited to this, and two or more cutting tools are stored in each of the storage units 1a to 1e. May be configured to be stored. The bracket 7 for holding the cutting tool may be omitted regardless of the number of the cutting tools stored.

A plurality of container connecting members 3 and 2 are provided.
It is optional which one of 3 and the lid connecting members 5 and 25 is irradiated with laser light to be provided with the notch (or to be cut). That is, all the container connecting members 3, 2
3 and the lid connecting members 5 and 25 may be provided with a cutout by irradiating a laser beam (cut), or only a specific one may be provided (cut). Of.

When irradiating the container connecting members 3 and 23 and the lid connecting members 5 and 25 with the laser light, it is preferable to irradiate from the same direction as the laser light for writing the identification information 11 as described above. Of course, it is possible to provide (cut) a notch by irradiating a laser beam from a direction different from this. Further, as described above, the irradiation of the laser beam is preferably performed after the storing step, but may be performed before the storing step.

The lid member 4 of this embodiment is constructed by applying a black paint to a white base material in consideration of the readability of the identification information 11 and the like. The configuration may be reversed so that, for example, a white paint is applied to a black base material. Further, the color combination of the base material and the paint is not limited to white and black, and it is naturally possible to use other colors (for example, gray). However, a neutral color (for example, blue)
Is not preferred. When the intermediate color is used, the identification information 11 with clear edges and contrast 11
This is because not only the error recognition rate of the barcode information 11c is deteriorated but also the reading operation itself by the reading device becomes impossible.

Although the identification information 11 is written in the lid members 4, 24, it may be written in the container members 2, 22 instead of or in addition to this. In the present embodiment, the identification information 11 by laser marking is exemplified by the tool specification information and the like, but other than that, for example, a warning text compliant with the PL method, a usage method, recycling information, or the like may be used. Further, in addition to the identification information 11 by laser marking, it is naturally possible to further provide information to the cutting tool storage container 1 by printing or a sticking label.

The laser marking of the identification information 11 may be performed by a method different from the method described in this embodiment. Here, such a method will be described. In this method, the lid members 4 and 24 are made of a resin material containing a heating element, and the heating element is heated by irradiating the surface thereof with laser light. By foaming and carbonizing the resin around the heating element, it is possible to form light and shade on the surfaces of the lid members 4 and 24, and by utilizing this, the identification information 1
Write 1.

When the identification information 11 is laser-marked by this method, polypropylene (PP), tetrafluoroethylene / perfluoroalkoxyethylene copolymer (PF) is used as the resin material for the lid members 4 and 24.
A), polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polycarbonate (PC), polyetherimide (PEI), polyetheretherketone (PEEK), polyester elastomer, etc. are preferably used, and these resins are preferably used. The color tone of the material is preferably white.

The heating elements contained in the resin material include Si, Ca, Na, K, C, Ti, Al and Mg.
Etc. can be used. The content rate of the heating element is
The amount is preferably 0.0001 to 0.5% by weight, more preferably 0.3 to 0.5% by weight. In addition,
These heating elements may contain only one kind, or may contain two or more kinds in combination.
