Description

  The present invention relates to an aqueous solution storage container that includes a wireless IC tag, constantly detects the type of aqueous solution, and detects the amount of liquid and the presence or absence of an aqueous solution, and an aqueous solution management device using the aqueous solution storage container.

  In general, the wireless IC tag does not have a built-in battery. However, when the wireless IC tag enters the electromagnetic wave region generated by the reader, the wireless IC tag is excited by the electromagnetic wave and power is supplied to the wireless IC tag. Further, since the electromagnetic wave generated by the reader includes a command, the operation principle is that when the wireless IC tag receives the command, information including the individual ID is returned to the reader.

  In this way, it is possible to communicate information in a non-contact manner with radio waves with a simple configuration, so it has been used in various fields including factory and distribution related inventory management. There are also things.

For example, the state of diapers is detected in the nursing field, and as shown in Patent Document 1, it is composed of a wireless IC tag and a moisture detection sensor for the purpose of providing a small, inexpensive and reusable aqueous solution detection sensor. There is something.
JP 2004-085277 A

  However, in this method, a special circuit other than the wireless IC tag (a resonance circuit composed of a coil and a capacitor) and a covering member for taking in the aqueous solution are added, and the covering member takes in the aqueous solution, and the characteristics of the circuit change. To determine whether it is wet or dry. In this way, it is structured to take the aqueous solution to be measured into the circuit configuration, and it is necessary to directly contact the aqueous solution, and targeting foodstuffs and pharmaceuticals is chemical, physical, and hygienic. There are many problems from various aspects such as psychological aspects, and it was not always suitable to use them for such things.

  Therefore, in order to solve the above-described conventional problems, the aqueous solution container of the present invention provides the first wireless IC tag in which the information about the aqueous solution or the code information for obtaining the information about the aqueous solution is written, from the aqueous solution. Attach or enclose the first wireless IC tag at a position that does not affect the wireless communication of the first wireless IC tag, and attach or enclose one or more second wireless IC tags other than the first wireless IC tag. Then, information on the aqueous solution is obtained by wireless communication with the first wireless IC tag, or code information that can acquire information on the aqueous solution is acquired, and the aqueous solution is determined based on whether the second wireless IC tag is capable of wireless communication. It was possible to determine whether or not

  Here, the second wireless IC tag uses a frequency band in the ultrashort wave or microwave region for wireless communication. Because of the characteristics of the wireless IC tag in that frequency band that is easily absorbed by the aqueous solution, if there is an aqueous solution in the vicinity of the second wireless IC tag, the aqueous solution itself absorbs electromagnetic waves for wireless communication, but wireless communication cannot be performed. When no aqueous solution is present in the immediate vicinity, wireless communication is possible.

  The aqueous solution storage container and the aqueous solution management apparatus using the aqueous solution storage container of the present invention are completely non-contact without the second wireless IC tag directly touching the liquid inside, and the aqueous solution is the second wireless IC tag. The frequency band in the ultra-high frequency or microwave region is used so that information can be communicated by radio waves only when it does not exist in the immediate vicinity of the radio wave (it cannot communicate if there is an aqueous solution in the vicinity of the second wireless IC tag). An aqueous solution storage container for detecting the amount of liquid and the presence or absence of an aqueous solution, and its aqueous solution, with a very simple configuration in which a general wireless IC tag is simply attached to or sealed in an aqueous solution storage container An aqueous solution management device using a storage container can be provided.

  In addition, the first wireless IC tag in which the information related to the aqueous solution or the code information that can acquire the information related to the aqueous solution is written is pasted or sealed at a position that is not affected by wireless communication at a predetermined distance from the aqueous solution. Therefore, even when the aqueous solution storage container is filled with the aqueous solution, only the first wireless IC tag can be read, and it is possible to know what kind of substance the aqueous solution is.

  According to a first aspect of the present invention, in the aqueous solution storage container, the first wireless IC tag is separated from the aqueous solution by a predetermined distance from the first wireless IC tag in which information relating to the aqueous solution or code information capable of acquiring information relating to the aqueous solution is written. The second wireless IC tag is attached or sealed at a position that does not affect the wireless communication of the tag, and one or more second wireless IC tags other than the first wireless IC tag are attached or sealed. The presence or absence of the aqueous solution can be determined based on whether or not wireless communication is possible.

  As a result, information can be read from the second wireless IC tag only when there is no aqueous solution in the aqueous solution storage container, so that the second wireless IC is no longer used for daily consumption such as soy sauce or sake. The tag can be detected without touching the aqueous solution directly. Furthermore, since the first wireless IC tag can be read even when the aqueous solution is filled in the aqueous solution storage container, it is possible to know what substance (here, soy sauce or sake) the aqueous solution is.

  According to a second aspect of the present invention, in the aqueous solution container, the first wireless IC tag is separated from the aqueous solution by a predetermined distance from the first aqueous IC tag in which information about the aqueous solution or code information capable of acquiring information about the aqueous solution is written. Affixed or sealed at a position that does not affect the wireless communication of the tag, and affixed two or more second wireless IC tags other than the first wireless IC tag at different positions in the height direction, or The amount of the aqueous solution can be determined based on whether or not the second wireless IC tag is capable of wireless communication.

  As a result, the information can be read from the second wireless IC tag only when there is no aqueous solution in the immediate vicinity of each second wireless IC tag, so that the aqueous solution that is consumed on a daily basis, such as soy sauce and sake, is reduced. The number of second wireless IC tags that can be read increases as the time goes on. The second wireless IC tag can calculate the consumption amount of the aqueous solution as well as the aqueous solution disappears without directly touching the aqueous solution. Further, even when the aqueous solution is filled in the aqueous solution storage container, only the first wireless IC tag can be read, so that it is possible to know what the aqueous solution is (here, soy sauce or sake).

  According to a third aspect of the present invention, in the aqueous solution container, the first wireless IC tag is separated from the aqueous solution by a predetermined distance from the first wireless IC tag in which information about the aqueous solution or code information capable of acquiring information about the aqueous solution is written. Affixing or enclosing at a position that does not affect the wireless communication of the tag, and disposing one or more second wireless IC tags other than the first wireless IC tag near the outlet of the aqueous solution container, The presence or absence of the aqueous solution can be determined based on whether the two wireless IC tags can wirelessly communicate.

  Thereby, for example, it can be detected in a non-contact manner that the medicine in the infusion has run out. Furthermore, since the first wireless IC tag can be read even when the aqueous solution is filled in the aqueous solution storage container (here, the drip container), what kind of substance the aqueous solution is (here, glucose or antibiotics). You can know the type of medicine that you have.

  According to a fourth aspect of the present invention, particularly in the aqueous solution container according to any one of the first to third aspects of the invention, the first wireless IC tag is separated from the aqueous solution by a predetermined distance and affects wireless communication of the first wireless IC tag. In order to secure a position where there is no gap, a part of the aqueous solution container (side surface or bottom part) was affixed or enclosed in a part where the thickness was increased or a handle part of the aqueous solution container.

  As a result, even if the aqueous solution is filled in the aqueous solution storage container, the first wireless IC tag can be read, so that it is possible to know more reliably what kind of substance the aqueous solution is.

  In a fifth aspect of the invention, particularly in the aqueous solution container according to any one of the first to fourth aspects of the invention, the first wireless IC tag includes a rewritable memory area, and the rewritable memory area contains information on the aqueous solution, or Code information that can acquire information on aqueous solution was written.

  As a result, various types of aqueous solutions can be stored in the aqueous solution storage container, and information on the aqueous solution can be written in the first wireless IC tag, and the usage and reuse of the aqueous solution storage container can be expanded.

  In the sixth invention, particularly in the aqueous solution storage containers of the first to fifth inventions, the second wireless IC tag uses a frequency band near 2.45 GHz for wireless communication.

  Accordingly, the second wireless IC tag is more easily affected by the aqueous solution than the wireless IC tag having a low frequency band, and information cannot be read when there is a large amount of aqueous solution around the second wireless IC tag, so that reliable aqueous solution detection is possible.

  In a seventh aspect of the present invention, in the aqueous solution management apparatus, the first wireless IC tag is separated from the aqueous solution by a predetermined distance from the first wireless IC tag in which information about the aqueous solution or code information capable of acquiring information about the aqueous solution is written. The second wireless IC tag is attached or sealed at a position that does not affect the wireless communication of the tag, and one or more second wireless IC tags other than the first wireless IC tag are attached or sealed. Comprises an aqueous solution storage container capable of determining the presence or absence of the aqueous solution based on whether or not wireless communication is possible, and reading means for reading the information of the first and second wireless IC tags.

  As a result, data can be read from the second wireless IC tag only when there is no liquid in the liquid storage container. For example, the second wireless IC tag indicates that there is no longer a daily consuming liquid such as soy sauce or sake. It is possible to provide an aqueous solution management device that can detect without touching the liquid directly. In addition, when the liquid is filled in the liquid storage container, the first wireless IC tag can be read even if the second wireless IC tag cannot be read at all, so what kind of substance the liquid is (here, soy sauce or sake) Therefore, it is possible to provide an aqueous solution management device that can know whether it is.

  According to an eighth aspect of the present invention, in the aqueous solution management apparatus, the first wireless IC tag is separated from the aqueous solution by a predetermined distance from the first wireless IC tag in which information about the aqueous solution or code information capable of acquiring information about the aqueous solution is written. Affixed or sealed at a position that does not affect the wireless communication of the tag, and affixed two or more second wireless IC tags other than the first wireless IC tag at different positions in the height direction, or Information on the first and second wireless IC tags, and the aqueous solution storage container that can determine the amount of the aqueous solution based on whether the second wireless IC tag is capable of wireless communication, and And reading means for reading.

  As a result, data can be read from the second wireless IC tag only when there is no liquid in the immediate vicinity of each second wireless IC tag, so that liquids that are consumed on a daily basis, such as soy sauce and sake, are decreasing. The number of second wireless IC tags that can be read increases, so that it is possible not only to run out of liquid but also to calculate the consumption amount without the second wireless IC tag directly touching the liquid. An aqueous solution management device can be provided. In addition, when the liquid is filled in the liquid storage container, the first wireless IC tag can be read even if the second wireless IC tag cannot be read at all, so what kind of substance the liquid is (here, soy sauce or sake) Therefore, it is possible to provide an aqueous solution management device that can know whether it is.

  According to a ninth aspect of the invention, in particular, in the aqueous solution management device according to any one of the seventh to eighth aspects, electromagnetic waves from the outside are shielded.

  As a result, only the information of the wireless IC tag that exists only in the aqueous solution management device that is physically closed is read, so the aqueous solution management device that targets only the information of the wireless IC tag in the aqueous solution management device Can be provided.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. Further, the description will be made on the assumption that any of the aqueous solution storage container, the cup, and the drip container that appears in the embodiment is an aqueous solution storage container. It is also assumed that the aqueous solution container is made of a material that transmits electromagnetic waves. Further, an aqueous solution management device that stores the aqueous solution storage container and manages the entire aqueous solution storage container will be described.

(Embodiment 1)
FIG. 1 is a view showing an example of the aqueous solution storage container of the first and second inventions, and the second wireless IC tags 11A, 11B, and 11C are attached to the side surface, bottom, or near the bottom of the aqueous solution storage container 15. It is. Since there is a possibility of peeling off by sticking, it is also effective to enclose the second wireless IC tags 11A, 11B, and 11C in the aqueous solution storage container 15.

  It is assumed that the aqueous solution storage container 15 is stored in a standing state as shown in FIG. 1, and in this state, the first wireless IC tag 12 is located away from the liquid surface and does not affect wireless communication. Was attached or enclosed. Information on the aqueous solution stored in the aqueous solution storage container 15 is written in the first wireless IC tag 12 and can be read at any time regardless of the remaining amount of the aqueous solution.

  Here, in consideration of hygiene and chemical influences, it is most preferable to install the second wireless IC tags 11A, 11B, 11C so that they do not directly contact the aqueous solution inside the aqueous solution storage container 15. It is not completely prohibited to attach or enclose the two wireless IC tags 11A, 11B, and 11C in direct contact with the aqueous solution.

  In FIG. 1, a broken line portion a at the bottom of the aqueous solution container 15 indicates a portion containing an aqueous solution. In the drawing, there is no aqueous solution in the immediate vicinity of the second wireless IC tags 11A and 11B, and the second wireless IC There is an aqueous solution in the immediate vicinity of the tag 11C. Therefore, only the information of the second wireless IC tags 11 </ b> A and 11 </ b> B can be read by the reading device 13 and transmitted to the reading device 13. As described above, since the second wireless IC tags 11A, 11B, and 11C are affixed to the aqueous solution storage container 15, the second wireless IC tag that can be read changes depending on the water level of the aqueous solution. You can recognize if it has decreased.

  In addition, when there is no second wireless IC tag 11A, 11B and only 11C is affixed, the information of the second wireless IC tag 11C is displayed only when the aqueous solution in the aqueous solution storage container 15 is almost empty. The reading device 13 can read. The information of the second wireless IC tag 11C includes the ID of the aqueous solution storage container, the type of the aqueous solution, the manufacturer, and the like. For example, when the soy sauce runs out, the soy sauce bottle is automatically transmitted via the wireless IC tag 11C. It can be used to convey this fact to the central processing unit 14.

  However, it is assumed that all of the second wireless IC tags 11A, 11B, and 11C cannot be read when the remaining amount of the aqueous solution is large. In this case, it is possible to know what aqueous solution exists. The first wireless IC tag 12 is necessary because it disappears.

  That is, the first wireless IC tag 12 has information on the aqueous solution written therein, and is present at a position where it can be read at any time regardless of the remaining amount of the liquid. You can always know if it is stored. In this case, since the second wireless IC tags 11A, 11B, and 11C only know the presence or absence of an aqueous solution, the information written in these is sufficient to distinguish each wireless IC tag, As with the first wireless IC tag 12, it is not always necessary to retain information regarding the aqueous solution.

  If no information about the aqueous solution is written in the first wireless IC tag 12 and only code information is written, the information server 30 connected to the network 20 is connected based on the code information. Information regarding the aqueous solution needs to be acquired by the central processing unit 14. The information server 30 stores each piece of code information and information related to the aqueous solution in association with each other. Further, it is also possible to acquire necessary information from the information server 30 based on the information about the aqueous solution read from the first wireless IC tag 12.

(Embodiment 2)
2 and 3 are diagrams showing an example of the aqueous solution storage container according to the first to second or fourth inventions.

  As shown in FIG. 2, the cup 16 (as an aqueous solution container) includes the second wireless IC tag 11, and a broken line portion a indicates an aqueous solution that is a drink in the cup. In FIG. 2, since there is little drink and there is no moisture in the immediate vicinity of the second wireless IC tag 11, the reader 13 can read information from the second wireless IC tag 11. This information is transmitted to the processing device 14.

  However, in this case as well, as described in the first embodiment, information cannot be read from the second wireless IC tag 11 when the drink is poured into the cup 16, so in such a case, Even the presence of the cup 16 cannot be confirmed. For that purpose, the first wireless IC tag 12 is required.

  Also here, information including the type of drink is written in the first wireless IC tag 12, and even if the drink is stored in the cup bottom 16X with the cup bottom thickened, it has an effect. Since the first wireless IC tag 12 is attached or enclosed at a position where wireless communication can be performed without receiving the information, information can be read at all times regardless of the remaining amount of drink.

  If no information about the aqueous solution is written in the first wireless IC tag 12 and only code information is written, information about the aqueous solution is sent from the information server 30 on the network 20 based on the code information. Information needs to be acquired by the central processing unit 14.

  Of course, the wall surface of the cup 16 may be thickened and the first wireless IC tag 12 may be installed at a position away from the aqueous solution. A large handle such as a beer mug is attached and the first wireless IC tag 12 is attached to the position. The same effect can be obtained by installing the wireless IC tag 12.

  Further, consider a system apparatus using such a cup 16.

  For example, as shown in FIG. 3, when the cups 16A, 16B, and 16C are placed on the table 17, and the reader 13 is arranged so that the entire table 17 can be accommodated in the communication area, the drink in the cup 16C is reduced. Therefore, the information of the second wireless IC tag 11 of the cup 16C can be read by the reading device 13, and the information is transmitted to the reading device 13. The cups 16A and 16B cannot be read from the second wireless IC tag 11, but can be read from the first wireless IC tag 12 (not shown), so what kind of drink is still in a large amount (reduced) It is also possible to grasp that.

  The information from the first wireless IC tag 12 includes information relating to the table number and the type of drink. For example, the information is sent from the reader 13 and the central processing unit 14 placed at the waiter's standby location. Since it is possible to grasp in real time which table and which drinks are lost, it is possible to realize a high-quality customer service such as a waiter rushing with the corresponding drink. Also, if you have a drink that doesn't go down too much, you can recommend a different type of drink to your customers.

  Note that a plurality of tables may be used as communication areas by changing the arrangement method of the reading device 13 and the arrangement method of the desk 17. Even when a plurality of cups with reduced drinks exist in the communication area at the same time, the wireless IC tag retains a unique ID and can be used without any problem because it can identify each wireless IC tag.

  Also, it is an aqueous solution storage container placed on the table instead of a cup, and it provides customer service such as replenishing the contents before soy sauce and sauces remain in the container and customers make complaints It is possible as well. In addition, it is possible to know the existence of a source that is rarely used or reduced.

(Embodiment 3)
FIG. 4 is a view showing an example of the aqueous solution storage container according to the third invention. The second wireless IC tag 11 is affixed in the vicinity of the discharge port of the drip container 19, and the broken line part a is the inside of the drip container 19. The liquid level is shown.

  In FIG. 4, since there is no aqueous solution in the immediate vicinity of the second wireless IC tag 11, the reader 13 can read the information of the second wireless IC tag 11, and the read information is transmitted to the central processing device 14. For example, if the central processing unit 14 is installed in the nurse's waiting room, it is notified in real time that there is no drug in the infusion. Efficiency can be expected. In particular, in the case of severely ill patients, a further effect can be expected when the nurse call button cannot be pressed when the drip solution is used up.

  Here again, as in the first and second embodiments, the infusion container bottom 19X is installed in a portion where the bottom of the infusion container 19 is thickened or in a portion away from the aqueous solution corresponding to the handle portion. The first wireless IC tag 12 is installed. Thereby, regardless of the remaining amount of the drug in the aqueous solution and regardless of the installation direction of the infusion container, the information regarding the type of the aqueous solution (type of the medicine) is always transmitted to the first radio regardless of where the medicine is present in the infusion container. It can be read from the information of the IC tag 12.

  If no information about the aqueous solution is written in the first wireless IC tag 12 and only code information is written, information about the aqueous solution is sent from the information server 30 on the network 20 based on the code information. Information needs to be acquired by the central processing unit 14.

  Among the frequencies that can be used as a wireless IC tag in Japan, the 2.45 GHz wireless IC tag, which has the highest frequency band, is more susceptible to water and more sensitive to aqueous solutions than wireless IC tags in other frequency bands. Therefore, the second wireless IC tag used for detecting the presence or absence of an aqueous solution in the application of the present invention is optimal.

  Further, in the present embodiment, only a very limited use is used as an example, but the invention described in the first to sixth embodiments is basically applicable as long as it is an aqueous solution contained in a container. In this case, the same effect is obtained.

  The aqueous solution container described here is preferably made of a material that transmits electromagnetic waves, and may be a glass product such as a soy sauce bottle, a plastic bottle for drinking water, or a milk pack. Paper containers may be used. The target aqueous solution may also be water such as liquors such as sake and beer, or various aqueous solutions such as juice and pharmaceuticals.

  In addition, although demonstrated by the central processing unit 14, a simple processing apparatus may be sufficient.

  In the description so far, it has been assumed that information on the type of the aqueous solution has already been written in the first wireless IC tag 12, but there is no reason for limiting to this. That is, when the reading device 13 has not only the information of the first wireless IC tag 12 but also a writing function capable of writing in the rewritable memory area of the first wireless IC tag 12, the aqueous solution When the aqueous solution is stored in the storage container 15, it is also preferable to write information on the aqueous solution in a rewritable memory area of the first wireless IC tag 12.

  In this case, various types of aqueous solutions can be stored in the aqueous solution storage container 15, and the usage applications are expanded. For example, if such a mechanism is introduced into the cup 16, a carbonated drink, barley tea, or sparkling liquor is put into the cup 16, and the first of the cup 16 is added each time. It becomes possible to use such information as writing such drink information in a rewritable memory area of the wireless IC tag 12.

  Of course, if the information to be written in the rewritable memory area of the first wireless IC tag 12 is merely code information, the central processing unit stores information on the aqueous solution from the information server 30 on the network 20 based on the code information. 14 need to get.

  Although the first wireless IC tag and the second wireless IC tag are described as being different from each other, the second wireless IC tag stores the same information as the first wireless IC tag and is attached to the aqueous solution storage container. Alternatively, the sealing position may be different.

(Embodiment 4)
FIG. 5 is a diagram showing an example of the configuration of the aqueous solution management apparatus of the present invention. In FIG. 5, one or more second wireless IC tags 11A, 11B, 11C, and 11D are attached to the side surface, the bottom portion, or the vicinity of the bottom portion of the aqueous solution storage container 15 so as to be aligned in the height direction of the liquid surface. . Of course, since there is a possibility of peeling off by sticking, it is also effective to enclose the second wireless IC tags 11A, 11B, 11C, and 11D in the aqueous solution storage container 15.

  Although it is best to prevent the second wireless IC tag 11 from coming into direct contact with the liquid inside the aqueous solution storage container 15, the second wireless IC tag 11 is stuck or sealed so as to be in direct contact with the liquid. It is not forbidden at all.

  In FIG. 5, a broken line portion a at the bottom of the aqueous solution storage container 15 indicates a portion containing liquid. There is no liquid in the immediate vicinity of the second wireless IC tags 11 </ b> A and 11 </ b> B, and information is read from the reading unit 13. Is possible. Since there is a liquid in the immediate vicinity of the wireless IC tags 11C and 11D, it is impossible to read these pieces of information, so it can be determined that the liquid exists up to the position (height) of 11C.

  When the liquid in the aqueous solution storage container 15 runs out, all of the second wireless IC tags 11A, 11B, 11C, and 11D can be read out. The amount can be detected. Since the information of the second wireless IC tag can include information such as the ID of the aqueous solution storage container 15, the type of liquid, and the manufacturer, for example, when the soy sauce runs out, the soy sauce is passed through the second wireless IC tag 11. It can be used such that the bottle automatically notifies the control means 14 of the fact.

  However, when the liquid level is close to the spout of the aqueous solution storage container 15 (even in this case, the liquid does not reach the immediate vicinity of the first wireless IC tag), the second wireless IC tags 11A, 11B, and 11C. Since the liquid exists in the immediate vicinity of 11D, no information can be read from the second wireless IC tag, and even the presence of the aqueous solution container 15 cannot be detected.

  For this reason, it is preferable to attach or enclose the first wireless IC tag 12 at a position where the liquid does not reach to the nearest position, for example, near the lid, or at a position such as the tip of the handle.

  That is, even when the first wireless IC tag 12 is added at a position where it is clear that the liquid surface is not immersed in the liquid surface, such as near the cap of the aqueous solution storage container 15, even when the liquid is filled therein, the reading is always possible. This allows the bottle type to be read even if it is filled with liquid. Thereby, the aqueous solution management apparatus which can read the information of the 1st radio | wireless IC tag 12 even when the liquid is stored in the aqueous solution storage container 15 can be provided.

  The information of the first wireless IC tag 12 preferably includes information such as the type of liquid stored in the liquid storage container and the manufacturer. When the information of the first wireless IC tag 12 is code information such as a simple numerical value, the control means 14 sends information corresponding to the code information (here, the information from the information server 30 via the network 20). It is conceivable to obtain information such as the type of liquid stored and the manufacturer.

  As described above, the first wireless IC tag should contain information on the liquid contained in the liquid container, but the second wireless IC tag 11A for determining whether or not the liquid is present, For 11B, 11C, and 11D, information on the liquid stored in the liquid storage container is not essential, and each ID code may be a distinguishable ID code.

  The reading means 13 is preferably installed in a place where the inside of the aqueous solution management device 40 can be looked over. If the whole can be seen from one place, it is advantageous in terms of cost to install only one in the aqueous solution management device 40. . When the aqueous solution management device 40 is electromagnetically shielded, the readable wireless IC tag is physically restricted only within the storage space of the aqueous solution management device 40, so that only the liquid storage container in the storage space can be easily managed. be able to.

  Among the frequencies that can be used as wireless IC tags in Japan, the 2.45 GHz wireless IC tag, which is the microwave region with the highest frequency band, is more susceptible to water than wireless IC tags in other frequency bands. Since it reacts sensitively, it is most suitable for use in the application of the present invention (particularly, the second wireless IC tags 11A, 11B, 11C, and 11D).

  The description so far has been based on the premise that information on the type of liquid has already been written in the first wireless IC tag 12, but there is no reason for limiting to this. That is, in the case where the reading unit 13 has not only the information of the first wireless IC tag 12 but also a writing function capable of writing in the rewritable memory area of the first wireless IC tag 12, the aqueous solution It is also preferable to write information about the liquid in the rewritable memory area of the first wireless IC tag 12 each time the liquid is stored in the storage container 15.

  In this case, various types of liquid can be stored in the aqueous solution storage container 15, and the application is expanded. For example, if such a mechanism is introduced, a carbonated beverage, barley tea, or sparkling liquor is put in the aqueous solution storage container 15, and the first solution of the aqueous solution storage container 15 is added each time. It becomes possible to use such information as writing such drink information in a rewritable memory area of the wireless IC tag 12.

  Of course, if the information to be written in the rewritable memory area of the first wireless IC tag 12 is simply code information, the central processing unit 14 acquires information about the liquid from the server on the network based on the code information. There is a need to.

  In this embodiment, only a very limited application is used as an example. However, the invention described in Embodiments 1 to 4 is basically applicable as long as the liquid is contained in a container. This case has the same effect. The aqueous solution management device 40 described here is a refrigerator, and the aqueous solution storage container 15 may manage glass products such as soy sauce bottles, or may manage PET bottles for drinking water in the cupboard, Of course, the liquid to be used as the target liquid may be any liquid such as sake, beer, juice, medicine, or water, as well as the shape of the storage.

  As described above, the aqueous solution storage container of the present invention and the aqueous solution management apparatus using the aqueous solution storage container are completely non-contact without the second wireless IC tag directly touching the internal liquid, Only in the case where the second wireless IC tag does not exist in the immediate vicinity, information can be communicated by radio waves (cannot communicate if there is an aqueous solution in the vicinity of the second wireless IC tag). Is used. An aqueous solution storage container for detecting the amount of liquid and the presence or absence of an aqueous solution is very advantageous in terms of cost, with a very simple configuration in which a general wireless IC tag is attached to or sealed in an aqueous solution storage container, and its An aqueous solution management apparatus using the aqueous solution storage container can be provided.
