Description

  The present invention relates to a metal drum can having a metal top plate, a base plate, and a body.

  Steel drums are, for example, chemical products, liquid fats and oils such as petroleum, gasoline, and lubricating oil, liquid dangerous materials with relatively high viscosity, or contents that are difficult to put in and out of powder or solids, etc. It is a container suitable for filling and transporting. Such steel drums include a sealed type in which a ground plate is wound around a cylindrical body and a top plate is also wound and joined, and an open type in which the top plate is detachable from the body. Such various drums are attached with characters or barcodes displaying predetermined product information such as product names, contents components, producers, production locations, handling precautions, etc. Often done. This type of merchandise information display is usually printed directly on the outer surface of the container or printed and affixed to a label.

  However, in the above-mentioned attachment such as a label or printing, the display area, the size of characters to be displayed, the number of characters, etc. are limited, and the product information cannot be displayed sufficiently. Further, when a bar code is used, a flat display is required for reading, and reading becomes impossible due to scratches, dirt, and the like. Furthermore, there is a problem that the amount of information that can be encoded with a bar code is limited, and product information cannot be displayed sufficiently.

  RFID (Radio Frequency Identification) has been used as an attachment as a means for eliminating such disadvantages and inconveniences of conventional product information display and displaying necessary and sufficient product information simply and accurately. This is an ultra-compact communication terminal in which an IC chip for storing information and controlling communication and a wireless antenna for communication with a reader / writer are sealed with resin or glass and formed into a tag (tag) shape. Yes, it is also called IC tag, non-contact RFID, RFID tag and the like.

  Such an RFID can record sufficient information in the memory of the IC chip, and can exchange information without contact with a reader / writer, and there is no concern about contact wear, damage, dirt, etc. Since the RFID itself can be powered off, it can be processed, downsized, and thinned according to the object. Therefore, by using RFID, it is possible to record various information related to the product, such as the product name, weight, content, manufacturer name, manufacturing location, date of manufacture, expiration date, expiration date, etc. Become. In addition, a wide variety of product information, which is impossible with conventional product display using characters or barcodes, can be used simply by attaching a small and thin RFID to the product.

  On the other hand, since such an RFID uses magnetic flux generated on the RFID side for communication, a normal type RFID cannot be attached to a metal body functionally, but a metal that can function on a metal body. RFID is already on the market.

  Therefore, a steel drum can having an RFID for metal is, for example, management of contents stored in a steel drum can, that is, content information management (content type, expiration date or filling date, etc.), content use history, or It is assumed that the contents can be easily managed and the drum can be easy to use and easy to use for drum users.

JP 2010-61271 A

The above-mentioned patent document 1 discloses a management method in which a drum user himself / herself attaches an RFID to an existing steel drum can to manage contents.
On the other hand, a steel drum can manufacturer has not yet been able to provide a steel drum can to which a metal RFID can be attached and a steel drum can that is easy to use for a drum can user.
This is considered due to the following reasons.

  That is, the metal RFID attached to the steel drum can has a larger size, particularly a thickness dimension, compared to a normal type RFID. For example, when comparing the thickness of RFIDs with the same communication distance, the thickness of the normal type RFID is about 0.2 mm, whereas the metal RFID has a thickness of about 3 mm due to the structure for securing the communication function. ˜about 9 mm. Accordingly, when the metal RFID is simply attached to the surface of the steel drum, the metal RFID protrudes from the surface of the can. Therefore, when transporting and handling a steel drum, the metal RFID easily comes into contact with other articles or equipment, and the metal RFID is likely to be peeled off and damaged by this contact. In particular, as a general usage form of steel drums, a plurality of drums are often arranged and stored in a warehouse or the like. Accordingly, when the cans are arranged, the cans often come into contact with each other, and the metal RFID is easily peeled off and damaged. In addition, in the metal RFID, it is possible to artificially perform peeling or the like because the thickness is large as described above.

  If the metal RFID is simply affixed to the surface of the steel drum, the metal RFID is peeled off and damaged. As a result, for example, contents management as described above becomes impossible, and the characteristics of the RFID are utilized. It will disappear.

  Further, after the closure, the inside of the steel drum can is hermetically sealed, and the drum can surface is somewhat deformed due to a change in the can internal pressure due to a change in temperature or the like, and this deformation may be repeated. Therefore, when the above-mentioned metal RFID is simply stuck on the surface of a steel drum, the metal RFID is peeled off from the surface of the can due to the above deformation, or vibration of transportation and handling due to a decrease in adhesive force. Or it may be peeled off by contact, and the characteristics of RFID cannot be utilized.

  Steel drums are often stored outdoors, and environmental factors such as sunlight, air temperature, and rainwater act on metal RFIDs outdoors. Therefore, when the metal RFID is simply affixed to the surface of the steel drum, the metal RFID may be peeled off and damaged, and the characteristics of the RFID cannot be utilized.

  Furthermore, one of the utilization forms unique to steel drums is that they are recycled. That is, it is often used as a regenerated drum can by cleaning the inside of a steel drum once used, peeling off the outer surface coating by shot blasting of an iron ball, and repainting. In such a reproduction process, when the metal RFID is simply attached to the drum can surface as it is, the metal RFID is broken and peeled off by the shot blasting process. As a result, even in this case, the characteristics of RFID cannot be used. In particular, considering the nature of reusable drums that are repeatedly reused, the replayed drums require detailed trace management such as usage history. Therefore, there is a great disadvantage that the characteristics of RFID cannot be utilized in the reproduction drum can.

  In addition, as described above, since there are various RFID sizes, not limited to metal, it is not possible to specify a single attachment location. For example, even if an RFID is attached to a jig, the size can be adjusted according to the size. Tools are required. Therefore, there is a problem that the use of RFID itself is discouraged and the characteristics of RFID cannot be exhibited.

  Furthermore, although the subject at the time of attaching RFID as an attachment to a steel drum can so far was described, the attachment to be attached is not limited to RFID. In other words, the attached object corresponds to one in which at least one of peeling and damage occurs and its characteristics cannot be utilized.

  The present invention has been made in order to solve the above-described problems, and is a metal drum can to which an object to be attached can be attached, and can prevent at least one of peeling and damage of the object to be attached. It aims at providing the metal drum can which can demonstrate.

In order to achieve the above object, the present invention is configured as follows.
In other words, the metal drum can according to the first aspect of the present invention is a metal drum can having a metal top plate, a base plate, and a fuselage for attaching an RFID on the surface of at least one of the top plate, the base plate, and the fuselage. A holding portion having a wall portion surrounding the periphery of the RFID.

  According to the metal drum can of the first aspect of the present invention, the RFID is protected by the wall portion and prevented from being peeled off and damaged by including the holding portion that has the wall portion surrounding the RFID and to which the RFID can be attached. Is done. Therefore, it is possible to provide a steel drum can that can exhibit the characteristics of RFID and is easy to use for a drum can user.

  A metal drum that is an embodiment of the present invention will be described below with reference to the drawings. In each figure, the same or similar components are denoted by the same reference numerals. In addition, in order to avoid the following description from becoming unnecessarily redundant and to facilitate understanding by those skilled in the art, a detailed description of already well-known matters and a duplicate description of substantially the same configuration may be omitted. . Further, the contents of the following description and the accompanying drawings are not intended to limit the subject matter described in the claims.

In each embodiment described below, as a metal drum can, a steel drum can having an internal capacity of about 200 L as defined in JIS Z 1601 (2005 edition) is taken as an example, but the present invention is not limited thereto. It is a concept that includes more than 200L. Further, the metal drum can is a concept including not only a sealed type (tight head drum) in which a base plate and a top plate are wound and joined to the body, but also an open type in which the top plate is detachable from the body.
Further, in each of the following embodiments, RFID is taken as an example of an attachment that can be attached to a steel drum can. However, the present invention is not limited to RFID, and at least one of peeling and damage occurs so that the characteristics cannot be utilized. An object that can be attached to a steel drum can corresponds to an attached object.
Further, in each of the following embodiments, an example in which an RFID corresponding to an example of an attached object is attached to a steel drum can be described, but the steel drum in the first to third embodiments is described below. It is only necessary to have a holding portion, and it is not necessary to have an RFID corresponding to an example of an attached object. On the other hand, in the fourth embodiment, since the steel drum can does not have a holding portion, the steel drum can includes an RFID corresponding to an example of an attached object.

1st Embodiment;
1 to 5 show a steel drum can 100 according to the first embodiment. The steel drum 100 includes a hollow body 101 made of metal and having a cylindrical shape, a metal base plate 102 that closes the lower end opening of the body 101, and a metal top plate 103 that closes the upper end opening of the body 101. And have. 1 and 2 show the above-described hermetically sealed (tight head drum) steel drum can 100 in which the base plate 102 and the top plate 103 are wound around the body 101.

The steel drum 100 has a holding part 110 to which the RFID 180 can be attached on the surface 105 of at least one of the body 101, the ground plate 102, and the top plate 103. The holding part 110 has a wall part 111 that surrounds the periphery of the RFID 180. In the present embodiment, the holding unit 110 has a concave shape type as shown in FIG. 3 and a convex shape type as shown in FIG. 4, and can be appropriately used according to the mounting location of the RFID 180. . Note that the concave-shaped holding part 110 is numbered as a holding part 110A, and the convex-shaped type holding part 110 is numbered as a holding part 110B. 3 and 4 show a cross section of the holding unit 110 cut at a right angle to the longitudinal direction of the RFID 180. Although not shown, the vertical section of the holding unit 110 is similar to that shown in FIGS. 1 and 2 show the holding unit 110 of the holding unit 110A.
Further, as will be described in detail in a second embodiment to be described later, the holding unit 110 is a concept including the forms shown in FIGS. 6 and 7.

The concave holding portion 110 </ b> A is formed by being recessed with respect to the surface 105 of the steel drum can 100, and has a holding portion bottom surface 112 having a depth D of 1 mm or more and 9 mm or less with respect to the surface 105. The RFID 180 is attached to the holding unit bottom surface 112. Therefore, as shown in FIG. 3, the wall portion 111 exists around the RFID 180 attached to the holding portion bottom surface 112.
The holding unit bottom surface 112 is preferably designed to have a size corresponding to the size of the RFID 180 to be used in order to prevent the mounting position of the RFID 180 with respect to the holding unit 110A and the holding unit 110B from changing. Therefore, the size of the holding unit 110 may be changed in accordance with the size of the holding unit bottom surface 112. On the other hand, as described in a third embodiment to be described later, the holding unit 110 can be fixed to one size regardless of the size of the RFID 180 to be used.

  The convex holding portion 110 </ b> B has a wall portion 111 protruding from the surface 105 of the steel drum can 100, and a depth D of 1 mm or more and 9 mm or less with respect to the convex portion upper surface 113 corresponding to the top portion of the wall portion 111. The holding part bottom surface 112 having The RFID 180 is attached to the holding unit bottom surface 112. As shown in FIG. 4, the wall portion 111 exists around the RFID 180 attached to the holding portion bottom surface 112. In the form shown in FIG. 4, the holding unit bottom surface 112 and the surface 105 in the holding unit 110 </ b> B are at the same level in the depth D and the height direction 114 corresponding to the thickness direction of the RFID 180, but may be different. .

  Regarding the values of 1 mm to 9 mm at the depth D of the holding unit 110 </ b> A and the holding unit 110 </ b> B, “1 mm” is a value set based on the reason for processing and manufacturing the holding unit 110, and “9 mm” is the thickness of the RFID 180 and The value is set based on the reason for processing and manufacturing the holding unit 110.

Further, the wall portion 111 in the holding portion 110 has an inclined surface 115 inclined at an obtuse angle θ (FIG. 3) with respect to the holding portion bottom surface 112. The angle θ is about 135 degrees as an example.
Since the wall portion 111 has such an inclined surface 115, the magnetic flux formed by the RFID 180 attached to the holding portion bottom surface 112 can be prevented from being blocked by the wall portion 111, and the magnetic flux can be obliquely upward. It is possible to secure a spread of magnetic flux and achieve a good communication state with a wide communication orientation range of the RFID 180.
Note that the angle θ is 90 degrees when the rectangular parallelepiped-shaped RFID 180 fits in the holding unit 110 without a gap, so that communication centering on the upper surface of the RFID 180 is maintained well, and the communication distance is not shortened. However, since a wider transmission / reception area in the RFID 180 is preferable, the radio wave directivity inherent to the RFID 180 can be maintained by setting the angle θ more preferably in the range of 120 degrees to 150 degrees.

  In the holding unit 110 </ b> A and the holding unit 110 </ b> B described above, since the RFID 180 is directly attached to the metal holding unit bottom surface 112, a metal RFID is used as the RFID 180. For example, an adhesive or a double-sided adhesive tape is used to attach the metal RFID to the holding unit bottom surface 112. Here, for example, a product manufactured by Nitta Corporation can be used as the metal RFID, and the size of the RFID 180 is about 32 mm × about 120 mm × about 6 mm in an example of the metal RFID.

  In this embodiment, the holding unit 110A and the holding unit 110B have a surface 105 in at least one of the body 101, the base plate 102, and the top plate 103, which has a reduced number of aperture elements and increased elongation elements, for example, It is produced by performing so-called overhanging. By adopting the overhang processing, there is almost no distortion around the holding portion 110A and the holding portion 110B during the processing, and the occurrence of wrinkles on the surface 105 can be suppressed. As a result, the holding part 110 can be provided without deteriorating the beauty of the steel drum 100.

In the steel drum can 100 having at least one of the holding part 110A and the holding part 110B described above, the RFID 180 can be protected by the wall part 111 existing around the steel part by attaching the RFID 180 to the bottom face 112 of the holding part. It becomes. That is, compared with the case where the RFID 180 is simply attached to the surface 105 of the steel drum 100 as it is, for example, a force that causes the RFID 180 to peel from the lateral direction due to contact with an article such as a tool, equipment, or a person acts. Even in this case, the peeling force is not effectively applied or reduced by the wall portion 111, and the RFID 180 is prevented from being peeled off.
Further, the surface 105 on which the holding part 110A and the holding part 110B are processed is not easily deformed due to the shape effect. Therefore, even when an impact or stress is applied, it is possible to maintain the flatness of the holding unit bottom surface 112 to which the RFID 180 is attached. Also in this respect, the holding unit 110 can protect the RFID 180 from peeling and damage.
As a result, the characteristics of RFID can be exhibited, and a steel drum can that is easy to use and easy to use can be obtained for drum can users.

  Although it is preferable to design the depth D so that the upper surface of the RFID 180 does not protrude from the surface 105 or the upper surface 113 of the convex portion, even if it protrudes, most of the thickness of the RFID 180 is the wall of the holding unit 110. It is protected by the portion 111, and the above-described peeling and damage can be prevented.

Further, as shown in FIG. 5, the holding part 110 may be filled with a resin material 170 so as to seal the RFID 180 attached to the holding part 110. FIG. 5 shows the case where the resin material 170 is filled into the holding portion 110A. Of course, the resin material 170 may be filled into the holding portion 110B. FIG. 5 shows the case where the resin material 170 and the surface 105 are on the same plane, but they may be on different planes.
As the resin material 170, for example, a rubber-based elastomer can be used. Examples of rubber materials include natural rubber, styrene rubber (SBR), butadiene rubber (BR), chloroprene rubber (CR), butyl rubber (IIR), nitrile rubber (NBR), ethylene propylene rubber (EPM), and hypalon (CSM). Acrylic rubber (ACM), silicone rubber, urethane rubber, fluorine rubber, etc. can be used.

By filling the resin material 170, it is possible to prevent intrusion of liquids such as dust and rainwater around the RFID 180 inside the wall portion 111. Further, in the case of the holding portion 110 </ b> A, there is an advantage that the appearance on the outer surface of the steel drum can 100 can be improved by making the filled resin material 170 and the surface 105 the same surface.
In addition, when the steel drum 100 is left outdoors, rainwater or the like may collect on the top plate 103. Water has polarity and causes a communication failure to the RFID 180. When there is a need to provide the holding portion 110 on the top plate 103 in spite of such concerns, the top plate 103 is provided with a convex type holding portion 110B, and the holding portion 110B is filled with the resin material 170. Therefore, it is possible to avoid communication troubles caused by rainwater.
Further, since the resin material 170 protects the RFID 180 even when the outer surface coating is subjected to the shot blasting process of the iron ball, the RFID 180 can be prevented from being damaged because it is used as the above-described reproduction drum can.

  For ease of manufacturing, in one steel drum 100, the holding part 110 is usually one in the central part of the top plate 103 as shown in FIG. 1, or the central part of the body 101 as shown in FIG. In many cases, one is provided. However, as already described, the holding portion 110 can be provided on the surface 105 of at least one of the body 101, the base plate 102, and the top plate 103. Further, for example, when the holding units 110 are provided on the top plate 103, the number, location, orientation direction, and the above-described types (holding units 110A and 110B) are not limited. Similarly, when providing the holding | maintenance part 110 in the trunk | drum 101 and the baseplate 102, the number, a place, etc. are not limited. In addition, an example of a modification of the installation location of the holding unit 110 is illustrated by a two-dot chain line in FIGS. 1 and 2.

  In general, when the holding unit 110 is provided on the body 101, the holding unit 110A is selected because it is preferable that there is no unnecessary convex portion for aesthetic reasons, while the holding unit 110 is provided on the top plate 103. In the case where installation outdoor placement is also assumed, it is preferable to select the one provided with the holding portion 110B and filled with the resin material 170 as described above.

  Here, where the RFID 180 is attached to the body 101, the main plate 102, and the top plate 103 is determined by the drum user based on his / her convenience in the usage mode of the RFID 180. Therefore, as a drum can manufacturer, by providing the steel drum can 100 provided with the holding portion 110 on the surface 105 of at least one of the body 101, the base plate 102, and the top plate 103, the installation location of the RFID 180 can be provided to the drum can user. It becomes possible to provide a steel drum that is easy to use and easy to use for drum users, with a wider range of options.

A second embodiment;
6 and 7 show a steel drum can 100-2 according to the second embodiment. Similar to the steel drum can 100 described above, the steel drum can 100-2 corresponds to a sealed type (tight head drum) and an open type having a body 101, a base plate 102, and a top plate 103. The steel drum can 100-2 according to the second embodiment is different from the steel drum can 100 according to the first embodiment in that the holding unit 110 is described below.
Here, the holding unit 110 in the second embodiment described below is conceptually intended to be included in the holding unit 110 described above, although the form is different from that in the first embodiment.

  Both the holding unit 110 </ b> A and the holding unit 110 </ b> B described above are formed by directly extending and processing at least one of the body 101, the base plate 102, and the top plate 103. On the other hand, the holding part 110-2 shown in FIGS. 6 and 7 is a member made of a member different from the body 101, the base plate 102, and the top plate 103 and having a shape corresponding to the planar shape of the RFID 180 to be attached. For example, it is configured by a rectangular parallelepiped member and is separately attached to at least one of the body 101, the base plate 102, and the top plate 103. 6 and 7 show a cross section of the holding portion 110-2. Although not shown, the vertical cross section of the holding unit 110-2 is similar to that shown in FIGS.

  Here, FIG. 6 shows a form corresponding to the holding portion 110A, and an opening corresponding to the holding portion 110-2 is provided on the surface 105 of the body 101 or the like, and the opening of the holding portion 110-2 is provided in the opening. The form which hold | fitted and fixed the holding | maintenance part 110-2 by making the part upper surface 113 and the surface 105 into the same surface is shown. FIG. 7 shows a form corresponding to the holding part 110B, and shows a mounting form in which the holding part 110-2 is placed and fixed on the surface 105 of the body 101 or the like.

  As described above, the holding unit 110-2 has a concave portion in which a holding unit bottom surface 112 having a depth D is formed in a rectangular parallelepiped member, for example. Therefore, the periphery of the RFID 180 attached to the holding portion bottom surface 112 is surrounded by the wall portion 111.

Moreover, when using the holding | maintenance part 110-2, the material of the holding | maintenance part 110-2 is not specified, The product made from metal and resin is not ask | required. For example, when the resin holding unit 110-2 is used, the RFID 180 does not need to use a metal RFID, and a general-purpose normal type RFID 180 can be used. Therefore, the RFID 180 is a small one, particularly, for example, with a thickness of 0. A thing of several millimeters can be used, and the holding part 110-2 itself can be reduced in size. Therefore, it is possible to simplify the handling of the holding unit 110-2.
Moreover, you may fill the resin material 170 with respect to the holding | maintenance part 110-2.

  Since the holding portion 110-2 also has the wall portion 111, peeling and damage of the RFID 180 can be prevented as in the case of the holding portions 110A and 110B. As a result, the characteristics of RFID can be exhibited, and a steel drum can that is easy to use and easy to use can be obtained for drum can users.

  Further, as a specific effect when the holding unit 110-2 is used, regardless of the type of the RFID 180 to be used, in particular, when the resin holding unit 110-2 is used, the normal type RFID 180 can be used. The size of 110-2 can be reduced.

A third embodiment;
FIG. 8 shows a steel drum can 100-3 according to the third embodiment. Similar to the steel drum can 100 of the first embodiment described above, this steel drum can 100-3 also has a sealed type (tight head drum) and an open type having a body 101, a base plate 102, and a top plate 103. To do. Moreover, it has at least one of holding | maintenance part 110, ie, holding | maintenance part 110A, and holding | maintenance part 110B demonstrated in the steel drum can 100 of 1st Embodiment.
The steel drum can 100-3 according to the third embodiment is different from the steel drum can 100 according to the first embodiment in that an adjuster member 130 described below is included.

As already described, there are various sizes of the RFID 180 depending on factors such as the manufacturer, the type of RFID in the normal or metal type, and the like. In the first embodiment, the holding unit 110 is used in order to prevent the mounting position of the RFID 180 from changing with respect to the holding unit 110, specifically the holding unit bottom surface 112, that is, the mounting position is not varied. It has been described that it is preferable to design a size corresponding to the size of the RFID 180.
On the other hand, changing the size of the holding unit 110 may be troublesome in manufacturing, and it is convenient in manufacturing if the holding unit 110 can be fixed to one size regardless of the size of the RFID 180 to be used.

Therefore, the adjuster member 130 is used to enable the RFID 180 to be arranged at a specified position with respect to the holding unit bottom surface 112 of the holding unit 110 regardless of the various sizes of the RFID 180. The adjuster member 130 is designed in consideration of a size that allows mounting of the largest RFID 180 among the plurality of RFIDs 180 to be mounted. The holding portion 110 has a holding portion bottom surface 112 having a size that allows the adjuster member 130 thus designed to be attached without a gap. Therefore, the holding unit 110 is fixed to a certain size, and only the size of the RFID 180 attached to the adjuster member 130 changes.
For example, an adhesive or a double-sided adhesive tape can be used to attach the adjuster member 130 to the holding unit bottom surface 112. A similar method can be used for attaching the RFID 180 to the adjuster member 130.

The material of the adjuster member 130 is not specified, and may be made of metal or resin. For example, in the case of a metal adjuster member 130, the RFID 180 to be used is a metal RFID, and its thickness is relatively large. Therefore, the adjuster member 130 is preferably a thin metal plate from the relationship with the depth D in the holding portion 110. On the other hand, when the resin-made adjuster member 130 is used, the RFID 180 does not need to use a metal RFID, and a general-purpose normal type RFID 180 can be used. Therefore, it is not necessary to consider the thickness of the adjuster member 130 and the depth of the holding portion 110 can be designed to be relatively small.
Further, the resin material 170 may be filled into the holding portion 110 provided with the adjuster member 130.

Even when the adjuster member 130 is used, since the wall portion 111 of the holding portion 110 exists around the RFID 180, the peeling from the surface 105 of the RFID 180 and the damage to the RFID 180 are reduced as described in the first embodiment. It becomes possible to do. As a result, the characteristics of RFID can be exhibited, and a steel drum can that is easy to use and easy to use can be obtained for drum can users.

Similar to the steel drum can 100 of the first embodiment described above, the steel drum can 100-4 also includes a sealed type (tight head drum) and an open type having a body 101, a base plate 102, and a top plate 103. To do.
In the first to third embodiments described above, the holding unit 110 that holds the RFID 180 is provided. On the other hand, in the steel drum can 100-4 according to the fourth embodiment, a resin protective material 140 that covers and protects the RFID 180 is provided instead of the holding unit 110.

In FIG. 9, a metal RFID is used as the RFID 180, and the metal RFID 180 is directly attached to the surface 105 of at least one of the body 101, the base plate 102, and the top plate 103 with, for example, an adhesive. A steel drum 100-4 provided with a protective material 140 is shown.
Here, the surface 105 includes an outer surface of a large plug provided on the top plate 103.
Further, the resin protective material 140 may be a liquid that has a viscosity and is suspended and solidified on the metal RFID 180, or may be a molded body that is separately molded so as to have a concave portion that accommodates the metal RFID 180 in advance. May be.

FIG. 10 shows a steel drum 100-4 when a normal type RFID is used as the RFID 180. Since a normal type RFID is used, a resin attachment 141 is attached to the surface 105 of at least one of the body 101, the base plate 102, and the top plate 103 for attaching the RFID. A normal type RFID 180 is attached to the resin mounting member 141, and a resin protective material 140 is provided to cover the normal type RFID 180. As described above, the resin protective material 140 may be a viscous liquid or a molded body. Here, when the resin protective material 140 is a molded body, the fixing method with the resin mounting material 141 may be an adhesive, a double-sided adhesive tape, a fusion method, or the like.
In addition, even if it is a form using the resin mounting material 141, you may use metal RFID.

  The steel drum can 100-4 according to the fourth embodiment described above also includes the resin protective material 140 corresponding to the wall portion 111 surrounding the RFID 180, so that peeling from the surface 105 of the RFID 180 and damage to the RFID 180 are performed. Can be reduced. As a result, the characteristics of RFID can be exhibited, and a steel drum can that is easy to use and easy to use can be obtained for drum can users.

Moreover, the point which does not need to provide the holding part 110 with respect to the surface 105 is mentioned as an effect peculiar to the steel drum can 100-4 in 4th Embodiment. As a result, there is an advantage that the RFID 180 can be attached to the steel drum can more easily than in the first to third embodiments described above, and the attached RFID 180 can be protected more easily.
Further, as a specific effect when the resin protective material 140 is used together with the resin mounting material 141, regardless of the type of RFID 180 to be used, especially when the normal type RFID 180 is used, the resin mounting material 141 and the resin protective material are used. The 140 can be downsized.

  In each of the above-described embodiments, the RFID 180 having a rectangular shape with a planar shape is taken as an example. However, the RFID 180 corresponds to an RFID having an existing shape such as a square, a circle, or an ellipse. As already described, the holding unit 110, the holding unit 110-2, and the like have forms corresponding to the various RFID 180 shapes.

  Moreover, it is also possible to take the structure which combined each embodiment mentioned above, and it is also possible to combine the component parts shown by different embodiment.

  In the first to third embodiments described above, the holding unit 110, the holding unit 110-2, and the adjuster member 130 are described as those for the RFID 180. However, the holding unit 110 and the like are not limited to those for the RFID 180, and function as a holding unit or the like for attaching an attachment to be attached to the surface 105 of at least one of the body 101, the base plate 102, and the top plate 103. Is also possible.

  Still further, the steel drum 100 has a depth (D) of 1 mm or more and 9 mm or less and a length or width of 150 mm or less on the surface 105 of at least one of the body 101, the base plate 102, and the top plate 103. The steel drum can provided with the recessed part or the convex part may be sufficient. Here, the concave portion or the convex portion corresponds to a shape as shown in FIG. 3 or FIG. However, it is not intended to include the RFID 180 indicated by the two-dot chain line in FIGS. Moreover, this recessed part or convex part is the concept also including circular or an ellipse.

Further, in each of the above-described embodiments, in the case where a normal type RFID is used as the RFID 180, a mode in which a resin member is interposed between the surface 105 of the steel drum can 100 and the RFID 180 has been described. However, the present invention is not limited to this, and a normal type RFID can be obtained by providing a magnetic sheet (for example, manufactured by Shin Nippon Radio Wave Absorber Co., Ltd.) between the surface 105 of the steel drum can 100 and the RFID 180 instead of the resin member. It can also be used. By using the magnetic sheet, the configuration around the RFID 180 can be further reduced as compared with a mode in which a resin member is interposed.
Similarly, in the embodiment in which a metal RFID is used as the RFID 180 in the above-described embodiment, a normal type RFID can be used instead of the metal RFID by interposing a magnetic sheet between the surface 105 of the steel drum can 100 and the RFID 180. Can be used. Thereby, in the embodiment described above, particularly in the form of using the metal RFID 180 together with the holding units 110 and 110-2, it is expected that the configuration around the RFID 180 including the holding units 110 and 110-2 can be dramatically reduced. it can.
