Description

  The present invention relates to a display label to be bonded to a product, a product to which the display label is attached, and a packaging container for the product.

  In recent years, with the development of refrigeration technology and the distribution industry, consumers have increased the chances of eating and drinking fresh foods from farther production areas. In addition, due to improved traffic conditions, consumers are also seeing a dramatic increase in opportunities to purchase and eat fresh food at more distant stores. On the other hand, troubles such as food poisoning caused by eating and drinking the above-mentioned fresh foods are also increasing dramatically.

  As an example of a technique for solving the above-mentioned trouble, there is an egg expiration date display label disclosed in Patent Document 1.

  This egg expiration date display label is a label in which a expiration date display portion is provided on the surface of the tack paper base material, and the date of the expiration date is described in the expiration date display portion.

  Another example of a technique for solving the above problem is a time-temperature indicator system disclosed in Patent Document 2.

  This system is a label-type system having a paper or film substrate, and the paper or film substrate is coated with a coating containing a heat sensitive formulation. In the system, the heat-sensitive blend allows the color generation reaction to proceed under the influence of the ambient temperature. For this reason, it is possible to determine whether or not the expiration date of the fresh product has ended, based on whether or not the density of the color generated by the color generation reaction is a predetermined level.

JP 2000-003131 A (published January 7, 2000) Special table 2003-525464 (published August 26, 2003)

  However, in the egg expiration date display label of Patent Document 1, the expiration date described on the label is calculated in advance under an environment that is normally assumed, and the shipping box on which the egg expiration date display label is attached. However, since it is not possible to reflect the history of what environment has passed after sticking, there is a problem that consumers cannot accurately determine whether or not the eggs contained in the shipping box can be tasted. there were.

  For this reason, now that consumers purchase more fresh food at more distant stores, the above-mentioned egg expiration date display label can accurately determine whether or not an egg can be tasted. It was hard to say that it was a display (which can ensure the safety of consumers).

  On the other hand, in the system of Patent Document 2, only the cumulative amount of heat applied after sticking is reflected, and it becomes a standard for determining whether or not eating and drinking is possible. There is a problem that the growth state is not accurately reflected.

  For example, live bacteria have a temperature suitable for growth, and sustaining that temperature most contributes to the growth of live bacteria. However, in the system of Patent Document 2, even if a higher temperature lasts for a short time, Even if the lower temperature lasts for a long time, the display result will be the same.

  In addition, when fresh food is stored in an environment that changes in a temperature cycle in which low and high temperatures are repeated, the growth state of the live bacteria varies depending on the environment in each stage of the temperature cycle. Therefore, it is impossible to estimate the growth state of viable bacteria in a timely manner with a simple cumulative amount of heat.

  For this reason, it is difficult to say that the system disclosed in Patent Document 2 is a display that allows a consumer or the like to accurately determine whether or not a food can be tasted.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a display label or the like that can more accurately determine whether or not a product can be used than before.

The display label of the present invention is a display label affixed to a product in order to solve the above-mentioned problem, and the proliferating rate according to the environment may be included in the product in advance or in the future. And a viable cell containing portion containing a growth correlation viable cell that is correlated with each other,
A viable cell proliferating unit that receives and proliferates the proliferation-correlated viable cells from the viable cell accommodating unit;
In order for the degree of growth of the growth-correlated live bacteria in the viable cell growth part to be visually recognized from the outside, at least the viable cell growth part in a state where the environment of the live cell growth part is matched with the initial storage environment of the product And a viable cell growth display section.

  According to the said structure, the environment of the living microbe growth part is accommodated according to the initial preservation | save environment of goods. Here, the “initial storage environment” is, for example, a storage environment when a product is commercialized or manufactured (a display label is attached to the product). For this reason, by attaching the display label of the present invention to the product, for example, the product is displayed after the product is commercialized or manufactured (the display label is attached to the product) until it is supplied to consumers. The environment through which the viable bacterial growth portion of the label passes can be made substantially the same as the environment through which the product passes.

  “Proliferation-correlated live bacteria” correlates with live bacteria that may be included in the product in advance or in the future (hereinafter simply referred to as “viable bacteria included in the product”) with respect to the growth rate according to the environment. It is a viable bacteria. For this reason, the degree of growth of the growth-correlated live bacteria in the live-cell growth part that has received the growth-correlated live bacteria correlates with the degree of growth according to the environment of the live bacteria included in the product. Thus, the degree of growth of the growth-correlated live bacteria in the live cell growth part is a standard for estimating the degree of growth of the live bacteria included in the product.

  In addition, the degree of growth of growth-correlated live bacteria in the live cell growth section depends on the environmental history of the product that has passed from the time of commercialization or manufacture (at the time of labeling) to the consumer. It will be. For this reason, according to the display label of the present invention, whether or not the product can be used is more than the conventional display label that displays the elapsed time since the product was commercialized or manufactured (at the time of attaching the display label). More accurate determination can be made according to the history of the environment through which the product has passed.

  Therefore, according to the display label of the present invention, it is possible for a consumer of a product to more accurately determine whether or not the product can be used than before.

  Further, according to the above configuration, the viable cell growth display unit accommodates the viable cell growth unit so that the degree of growth of the growth correlated viable cell can be visually recognized from the outside.

  For this reason, since the degree of growth of the growth correlation live bacteria in the live cell growth part can be visually confirmed through the live cell growth display part, it is easy for consumers of the product to determine whether or not the product is usable. Can be judged.

  As described above, according to the display label of the present invention, compared with the conventional display label on which the usable period of the product is simply printed, the consumer of the product can easily determine whether or not the product can be used. More accurate judgment can be made.

  As described above, the “growth-correlated viable bacteria” may be a viable microorganism that correlates with the viable bacteria contained in the product with respect to the growth rate according to the environment. It may be a live bacterium or a different type of live bacterium.

  Further, in addition to the above-described configuration, the display label of the present invention is such that the viable cell growth display portion is transparent so that the viable cell growth portion is sealed inside and the viable cell growth portion can be visually recognized from the outside. It is preferable to provide a sealing bag made of a material.

  According to the above configuration, by configuring the sealing bag with a translucent material so that the viable cell growth part can be visually recognized from the outside, The degree of growth can be visually recognized, and the degree of growth of viable bacteria contained in the product can be estimated.

  Because, the growth correlation live bacteria attached to the end of the viable cell growth part receiving the growth correlation live bacteria, the region where the growth correlation live bacteria exist on the live cell growth part is expanded from the end. This is because the expanded region and the enlarged region can be distinguished from other regions where there is no growth-correlated live bacteria, and thus the degree of proliferation can be easily confirmed.

  Therefore, according to the display label of the present invention, it is easier and more convenient for the consumer of the product or the like to determine whether or not the product can be used as compared with the conventional display label on which the usable period of the product is simply printed. It can be judged accurately.

  In addition to the above configuration, in the display label of the present invention, it is preferable that the growth-correlated live bacteria are live bacteria that are harmless to the living body.

  Further, in addition to the above configuration, the display label of the present invention is a position on the side where the degree of growth of the growth-correlated live bacteria in the live-cell growth part can be visually recognized, and the end on the side receiving the growth-correlated live bacteria The mark which shows the time limit which can use the said goods may be attached to the vicinity of the position which only the predetermined distance left | separated from the part in the direction which the said proliferation expands.

  According to the above configuration, the growth-correlated live bacteria that proliferate in the live-cell growth part can be obtained by setting the usable period of the product in advance according to the degree of growth of the growth-correlation live bacteria in the live-cell growth part. It is possible to easily compare the position indicating the degree of proliferation, which is the position where the existing area has been enlarged, and the position of the mark indicating the usable period of the product. For this reason, the consumer can estimate how much the proliferation of viable bacteria contained in the product with the display label attached is relative to the expiration date for use of the product.

  Further, in addition to the above configuration, the display label of the present invention is a position on the side where the degree of growth of the growth-correlated live bacteria in the live-cell growth part can be visually recognized, and the end on the side receiving the growth-correlated live bacteria An entry space in which a mark indicating the expiration date for use of the product may be secured in the vicinity of a position away from the portion by a predetermined distance in the direction in which the proliferation increases.

  According to the above configuration, the space for filling the display area of the viable cell growth display section is secured, so that the label labeler can freely use the time limit that can be used according to the type of product to which the display label is to be affixed. Since it can be changed and filled in, it is not necessary to prepare a display label for each product having a different usable time limit, and the cost of mass production of the display label can be reduced.

  The entry space may be in the vicinity of a position where the degree of growth of the growth-correlated live bacteria can be visually recognized in the same manner as described above.

  In addition to the above configuration, the display label according to the present invention includes an end on the side of delivering the growth-correlated viable bacteria in the viable cell storage unit, and a side on the side of receiving the growth-correlated live bacteria of the viable cell growth unit. It is preferable to provide a transfer start means for starting transfer of the growth-correlated live bacteria between the end portions.

  According to the said structure, the sticker who affixes a display label to goods can freely set the time which starts giving and receiving of the said growth correlation live microbe.

  For this reason, before starting to give and receive the above-mentioned growth-correlated live bacteria, the growth of the growth-correlated live bacteria on the display label proceeds on its own, and the display labels are stocked without completing the growth of the growth-correlated live bacteria. Can do. Therefore, it is possible to reduce the cost of mass production of display labels when sticking to a product, and to prevent the display labels from being insufficient.

  In addition, the history of the environment through which the product has passed can be reflected on the display label from the time when the transfer of the growth-correlated live bacteria is started until it is supplied to consumers.

  Further, in addition to the above-described configuration, the display label of the present invention includes an end portion on the side of receiving the growth-correlated live bacteria of the viable cell growth portion, and a side of delivering the growth-correlated viable bacteria of the viable cell storage portion. A blocking portion for blocking the transfer of the growth-correlated live bacteria from occurring to the end portion may be provided, and the blocking portion may be removable from the display label.

  According to the said structure, the sticker of a display label can start giving and receiving of a growth correlation live microbe between a live microbe growth part and a live microbe accommodating part by removing a prevention part from a display label. Become.

  For this reason, the use time of the display label can be adjusted by attaching and detaching the blocking portion.

  The display label of the present invention includes a detection unit that detects the degree of growth of the growth-correlated live bacteria in the viable cell growth part, and whether or not the degree of growth of the growth-correlated live bacteria is detected by the detection unit. It may further comprise a transmission unit for transmitting notification information for reporting.

  According to the above configuration, it is possible to detect the degree of growth of the growth-correlated live bacteria depending on whether the notification information is transmitted from the transmission unit.

  For example, when the transmitting unit is ready to transmit and the acquired notification information indicates that the degree of growth of the growth-correlated live bacteria is detected by the detection unit, the degree of growth of the growth-correlated live bacteria You may consider that is detected. Further, the notification information acquired when the transmitter is ready to transmit indicates that the degree of growth of the growth-correlated viable bacteria is not detected by the detector, and the notification information is acquired from the transmitter. When it disappears, it may be considered that the degree of growth of the growth-correlated live bacteria has been detected.

  Thereby, even if it is a case where goods cannot be recognized visually, such as being in a refrigerator, it can be checked whether it is within the expiration date.

  In the display label of the present invention, the transmitter may be a passive contactless authentication tag.

  According to the above configuration, the passive type non-contact authentication tag [passive type RF (Radio Frequency) tag, passive type radio IC (Integrated Circuit), passive type IC tag] is an active type RF tag [active type RF tag, active type tag]. Unlike a wireless IC and an active IC tag, a battery is not required for operation, so that the product state can be confirmed even for a product with a long shelf life and a long service life.

  Moreover, the display label of this invention may be provided with two or more said transmission parts.

  According to the above configuration, even if one of the transmission units does not operate, the product is consumed by detecting a transmission from another transmission unit, or the product does not exist on the spot, but the product exists, but the taste is good. You can check if the deadline has expired.

  In the display label of the present invention, the passive RF tag may be a 13.56 MHz band passive RF tag.

  According to the above configuration, when an RFID (Radio Frequency Identification) reader is provided in a refrigerator or the like to detect a product, the occurrence of a null point can be reduced, so that the degree of freedom of the installation location of the RFID reader is increased.

  Moreover, in addition to the said structure, it is preferable that either the said display label is affixed on the goods or the packaging container of goods of this invention.

  According to the said structure, it becomes possible for a consumer etc. to judge more easily and correctly whether goods can be used for the reason mentioned above.

  An embodiment of the present invention will be described with reference to FIGS. Descriptions of configurations other than those described in the following specific embodiments may be omitted as necessary, but are the same as those configurations when described in other embodiments. For convenience of explanation, members having the same functions as those shown in each embodiment are given the same reference numerals, and the explanation thereof is omitted as appropriate.

[Embodiment 1]
First, based on FIG. 1, the structure of the expiration date display label (display label) 1 which is one Embodiment of this invention is demonstrated. FIG. 1A is a top view showing the expiration date display label 1, and FIG. 1B is a dd sectional view thereof. In addition, below, it demonstrates taking the case of the expiration date display label 1 which displays the expiration date, such as a foodstuff, as one Embodiment of the display label of this invention. However, the display label of the present invention is not limited to such a display label. For example, the display label of the present invention is a display label for displaying the fermentation state of fermented food and drink products, a cleaning liquid and cosmetics, in addition to a display label for displaying the taste or expiration date to be affixed to the food surface and / or food packaging container. It can also be applied to display labels that display the quality of products other than foods such as.

(Expiration date label 1)
The expiration date display label 1 of this embodiment is a display label affixed to a product or its packaging container. Further, as shown in FIG. 1B, the expiration date display label 1 includes a viable cell growth display unit 3, an adhesive layer 40, a mount 50 and an adhesive layer 60 in order as viewed from the direction indicated by the arrow B. In other words, the “direction indicated by the arrow B” is a direction viewed from the side on which the expiration date such as food of the expiration date display label 1 is displayed.

(Live bacteria growth display part 3)
The viable cell growth display unit 3 includes a sealing bag 10 in which a viable cell storage unit 6 and a culture medium (viable cell growth unit) 20 are stored.

(Live bacteria storage 6)
In the viable cell accommodating section 6, a growth-correlated viable cell is accommodated. Here, “growth-correlated live bacteria” are mutually connected to live bacteria that may be included in the product in advance or in the future (hereinafter simply referred to as “viable bacteria included in the product”) with respect to the growth rate according to the environment. It is a viable correlate.

  In the present embodiment, the sealing bag 10 in which the viable cell storage unit 6 is stored is made of a transparent polyethylene film having a thickness of 50 μm. However, as will be described later, the portion of the sealing bag 10 in which the viable cell container 6 is accommodated is composed of an aluminum bag [material: PET16 / dry / CP vapor deposition 40 (FKA)] or the like, and the growth correlation. You may make it preserve | saving a living microbe.

(Medium 20)
The culture medium 20 receives the growth-correlated live bacteria from the live-cell storage unit 6 and grows the growth-correlated live bacteria.

  In the present embodiment, as described above, the sealing bag 10 in which the culture medium 20 is accommodated is made of a transparent polyethylene film having a thickness of 50 μm. However, as will be described later, the portion of the sealing bag 10 in which the culture medium 20 is accommodated may be formed of a polyolefin-based stretch film or the like.

  In the expiration date display label 1 of the present embodiment, as shown in FIG. 1B, at the time of manufacturing the expiration date display label 1, the end of the culture medium 20 on the side that receives the growth-correlated viable bacteria and the growth correlation are displayed. A point A is in direct contact with the end on the side that delivers live bacteria. For this reason, the culture medium 20 receives the growth-correlated live bacteria from the live-cell storage unit 6 at the time of manufacture of the expiration date display label 1, and the growth of the growth-correlated live bacteria is started from the same point.

  Moreover, the culture medium 20 is accommodated according to the initial storage environment of the product. Here, the “initial storage environment” is, for example, a storage environment at the time when the product is commercialized or manufactured (the expiration date display label 1 is attached to the product). For this reason, by sticking the expiration date display label 1 to the product, for example, from when the product is commercialized or manufactured (the expiration date display label 1 is attached to the product) until the product is supplied to consumers, etc. Meanwhile, the environment through which the medium 20 of the expiration date display label 1 passes can be made substantially the same as the environment through which the product passes.

  For this reason, the degree of growth of the growth-correlated live bacteria in the medium 20 that has received the growth-correlated live bacteria correlates with the degree of growth corresponding to the environment of the live bacteria included in the product. Thus, the degree of growth of the growth-correlated live bacteria on the medium 20 serves as a standard for estimating the degree of growth of the live bacteria included in the product.

  Further, the growth-correlated viable bacteria attached to the medium 20 may be viable bacteria having a correlation with the viable bacteria contained in the product with respect to the growth rate according to the environment, and the same type of viable bacteria as the live bacteria contained in the product. Or different types of viable bacteria.

  The growth-correlated live bacteria are preferably selected according to the product to which the expiration date display label 1 is affixed. For example, when the product is a food or drink, whether or not the affixed product can be eaten or consumed is often determined. It may be a live microbe determined in some cases.

  However, since the growth-correlated live bacteria may adhere to the product to which the expiration date display label 1 is attached in the event of leakage, the same growth tendency as the live bacteria contained in the product (according to the environment) It is desirable that the living bacteria be harmless to a living body exhibiting a growth rate).

  This is because the expiration date display label 1 exists on or in the vicinity of the product, and the growth-correlated live bacteria contained in the expiration date display label 1 can adhere to the product due to some trouble. It is because the influence of can be suppressed.

  The “living body” includes animals other than humans. For example, a zoo staff may purchase animal food as a product.

  In this embodiment, the viable bacteria storage unit 6 accommodates bifidobacteria showing a growth tendency (or growth rate) according to the same environment as that of Escherichia coli as the growth correlation live bacteria. Specific examples of growth-correlated live bacteria include yeast and koji molds in addition to bifidobacteria.

  The bifidobacteria are already attached to the end (point A) of the culture medium 20 on the side that receives the growth-correlated live bacteria at the time of production of the expiration date display label 1.

  The culture medium 20 is composed of, for example, agar having a thickness of 1 mm, a length of 30 mm, and a width of 5 mm.

  Further, the end on the side that receives the growth-correlated viable bacteria is one end (point A) in the longitudinal direction of the culture medium 20 (left-right direction with respect to the paper surface).

  The shape, size, and material of the culture medium 20 are not particularly limited as long as the growth-correlated live bacteria can grow and the presence of the grown growth-correlated live bacteria can be visually confirmed.

  As described above, the growth-correlated live bacteria adhere to the end of the culture medium 20 on the side where the growth-correlated live bacteria are received, so that the end (point A) of the culture medium 20 and the other end (with respect to the paper surface). The growth of the growth-correlated live bacteria starts toward the right end).

  For this reason, the progress of the growth of the growth-correlated viable bacteria in the medium 20 is changed from the adhesion end (point A; the left end with respect to the paper surface) to the growth end (the other end in the longitudinal direction of the medium 20; with respect to the paper surface). The distance to the right end) can be confirmed at a visual level.

  According to the above configuration, the degree of growth of the growth-correlated live bacteria in the medium 20 that has received the growth-correlated live bacteria correlates with the degree of growth according to the environment of the live bacteria included in the product. Thus, the degree of growth of the growth-correlated live bacteria on the medium 20 serves as a standard for estimating the degree of growth of the live bacteria included in the product.

  In addition, the degree of growth of the growth-correlated live bacteria on the culture medium 20 is based on the environmental history of the product that has passed from the time of commercialization or manufacture (when the expiration date display label 1 is applied) to the time when it is supplied to consumers or the like. It will be a response. For this reason, according to the expiration date display label 1, the history of the environment in which the product has passed can be compared with the conventional display label that simply displays the time elapsed since the product was commercialized or manufactured. Accordingly, it can be judged more accurately.

  Therefore, according to the expiration date display label 1, the consumer of the product can more accurately determine whether or not the product can be used than the conventional display label.

  Moreover, according to the said structure, the culture medium 20 is accommodated in the viable cell growth display part 3 so that the growth degree of a growth correlation viable cell can be visually recognized from the outside.

  For this reason, since the degree of growth of the growth-correlated live bacteria in the culture medium 20 can be visually recognized through the live cell growth display unit 3, the consumer of the product can easily determine whether or not the product can be used. Judgment can be made.

(Sealing bag 10)
The sealing bag 10 is preferably made of a translucent material that allows the culture medium 20 to be visually recognized from the outside. For example, in the present embodiment, the sealing bag 10 is made of a transparent polyethylene film having a thickness of 50 μm.

  In addition, the material of the sealing bag 10 is preferably a material that can prevent leakage of the growth-correlated live bacteria that are enclosed so that the growth-correlated live bacteria can be prevented from adhering to the outside. Specifically, any transparent film such as cellophane, vinyl chloride, polyethylene, polypropylene, polyester, polyimide, polycarbonate, or polystyrene may be used in addition to the transparent polyethylene film.

  In addition, since a polyolefin stretch film for food packaging is used for food packaging, when the product is a food, the constituent material of the sealing bag 10 is the above polyolefin stretch film or the like. Is preferred. However, the entire sealing bag 10 does not need to be configured with a polyolefin-based stretch film or the like. As described above, a part of the sealing bag 10 is configured with a polyolefin-based stretch film or the like, and a part of the sealing bag 10 is configured. May be an aluminum bag [material: PET16 / dry / CP vapor deposition 40 (FKA)] or the like.

  According to the above configuration, the degree of growth of the growth-correlated live bacteria in the culture medium 20 after receiving the growth-correlated live bacteria by configuring the sealing bag 10 with a translucent material so that the culture medium 20 can be visually recognized from the outside. And the degree of growth of viable bacteria contained in the product can be estimated.

  This is because the growth-correlated live bacteria attached to the end of the culture medium 20 that receives the growth-correlated live bacteria grows so that the region where the growth-correlated live bacteria exist on the culture medium 20 expands from the end. This is because the expanded area can be distinguished from other areas where there is no growth-correlated live bacteria, and the degree of proliferation can be easily confirmed.

  Therefore, according to the expiration date display label 1, it is easier and more convenient for the consumer of the product to determine whether or not the product can be used as compared with the conventional display label on which the product usable period is simply printed. Judgment in a timely manner.

  The top film 10a of the sealing bag 10 preferably has a high transmittance in the visible light region so that a consumer or the like can visually confirm the encapsulated medium 20 described later. Specifically, the transmittance is desirably 80% or more in the visible light region. Moreover, the upper surface film 10a and the lower surface film 10b may be produced integrally, or may be produced as separate bodies. In addition, when it produces as a different body, the material of the upper surface film 10a and the material of the lower surface film 10b may not be the same.

  In addition, about each thickness of the upper surface film 10a and the lower surface film 10b, if there is no problem in the above-mentioned conditions, intensity | strength, etc., it will not specifically limit.

(Adhesive layer 40 and adhesive layer 60)
The adhesive layer 40 and the adhesive layer 60 are made of, for example, an acrylic adhesive having a thickness of 20 μm. The thickness and material of the adhesive layer 40 and the adhesive layer 60 are not limited to the above, and any material can be used as long as it can adhere a lower surface film 10b of the sealing bag 10 and a mount 50 described later. Specific examples include Olivevine BPS3233D manufactured by Toyo Ink Manufacturing Co., Ltd.

(Mount 50)
The mount 50 is made of tack paper having a thickness of 75 μm, for example. The mount 50 can be written with a food name, a mark indicating the expiration date, or the like, and is not particularly limited as long as there is no problem in strength or the like.

(Mark S)
As shown in FIG. 1B, the expiration date display label 1 is a position on the surface of the mount 50 on the side where the viable cell growth display portion 3 can be visually recognized, and is predetermined from the point A that can be recognized by the consumer. Is marked with a mark S so that it can be determined whether or not it is within the expiration date.

  More specifically, it is a position on the side where the growth degree of the growth-correlated viable bacteria in the culture medium 20 can be visually recognized, and is determined in a direction in which the growth expands from the end (point A) on the side receiving the growth-correlated viable bacteria. A mark S is attached in the vicinity of a position separated by a distance.

  The mark S may be attached in advance when the expiration date display label 1 is manufactured, or depending on the state of the food, the type of food, etc., when the expiration date display label 1 is applied to the surface of the food or the food packaging container. You may attach. Of course, the mark S is not limited to a triangle. For example, a downward arrow “↓” or the like may be attached to a circle or paper.

  According to the above configuration, by setting the usable period of the product in advance according to the degree of growth of the growth-correlated live bacteria on the medium 20, the region where the growth-correlated live bacteria that grow on the medium 20 are present. It is possible to easily compare the position indicating the degree of proliferation, which is the position reached by the enlarged area, with the position of the mark S indicating the expiration date for use of the product. For this reason, the consumer can estimate how much the proliferation of viable bacteria contained in the product to which the expiration date display label 1 is attached is relative to the expiration date for which the product can be used.

  Moreover, it is a position on the side where the degree of growth of the growth-correlated live bacteria in the culture medium 20 can be visually recognized, and is separated from the end (point A) on the side receiving the growth-correlated live bacteria by a predetermined distance in the direction in which the growth expands. An entry space in which a mark S indicating the expiration date for use of the product can be entered in the vicinity of the position.

  According to the said structure, the sticker of the expiration date display label 1 can be used according to the kind of goods which affix a display label because the entry space is ensured on the surface of the viable cell growth display part 3. Since the deadline can be freely changed and filled in, it is not necessary to prepare a display label for each product with a different usable deadline, and the cost of mass production of the display label can be reduced.

  The entry space may be in the vicinity of a position where the degree of growth of the growth-correlated live bacteria can be visually recognized in the same manner as described above.

[Embodiment 2]
The best-before date display label (display label) 2 according to another embodiment of the present invention will be described with reference to FIGS. 2 (a) to 2 (d).

  FIG. 2A is a top view showing the expiration date display label 2, and FIG. 2B shows the state before the blocking unit 11 is removed with respect to the expiration date display label 2 shown in FIG. Fig. 2 (c) is a dd cross-sectional view showing a state after removal of the blocking portion 11, and Fig. 2 (d) is a view after attaching viable bacteria (growth-correlated viable bacteria). It is dd sectional drawing which shows the state of.

  The best-before date display label 2 of the present embodiment is different from the best-before date display label 1 in that a live cell growth display unit 3 a having a transfer start and reception means 5 is provided instead of the live cell growth display unit 3. Is a point. Therefore, in the following, only the viable cell growth display unit 3a will be described, and description of other components will be omitted.

(Live bacteria growth display part 3a)
As described above, the expiration date display label 2 of the present embodiment is configured to include the viable cell growth display unit 3 a having the transfer start and stop means 5 instead of the viable cell growth display unit 3 of the expiration date display label 1. It is a point. In other words, the transfer start means 5 is connected to the end portion P1 of the viable cell storage unit 6 that receives the growth-correlated viable bacteria and the end portion P2 of the culture medium 20 that receives the growth-correlated viable cells. It may be read as a connection (start) means for starting.

  The transmission / reception start means 5 may adopt any configuration as long as it has a function of starting the transmission / reception of growth-correlated live bacteria between the end P1 and the end P2. .

  According to the giving / receiving start means 5, it is possible to freely set the time when the paster of the expiration date display label 2 starts giving / receiving the growth correlated viable bacteria.

  For this reason, before the start of giving and receiving of the growth correlation viable bacteria, the growth of the growth correlation viable bacteria on the expiration date display label 2 proceeds without permission, and the expiration date display label is completed without completing the growth of the growth correlation live bacteria. 2 can be stocked. Therefore, it is possible to reduce the cost of mass production of display labels when sticking to a product, and to prevent the display labels from being insufficient.

  In addition, the history of the environment through which the product has passed can be reflected in the expiration date display label 2 from the time when the transfer of the growth-correlated live bacteria is started until the product is supplied to consumers and the like.

  More specifically, as shown in FIG. 2 (b), the delivery start means 5 receives the end portion P2 on the side of the culture medium 20 that receives the growth-correlated viable bacteria and the growth-correlated viable bacteria in the viable cell storage unit 6. It is provided between the end P1 on the passing side. Further, in the transfer start / stop means 5, a blocking portion 11 is provided between the end portion P1 and the end portion P2. Due to the blocking unit 11, the culture medium 20 and the viable cell storage unit 6 are separated from each other, and the medium 20 and the viable cell storage unit 6 are in direct contact with each other. And different.

  Further, the portion of the upper surface film 10 a of the sealing bag 10 where the lower end of the blocking portion 11 is provided (hereinafter simply referred to as “lower end portion”) is bonded to the adhesive portion 70, and the lower end portion of the adhesive portion 70 The surface on the side opposite to the adhesive surface is adhered to the lower film 10b.

  In the state shown in FIG. 2 (b), the transfer start / stop means 5 holds the blocking portion 11 with a finger and pulls up (removes) it in the direction indicated by the arrow C, whereby the lower end portion of the top film 10 a and the adhesive portion 70 is peeled off, and a gap is formed between the end P1 and the end P2 (see FIG. 2C).

  Next, assuming that the growth-correlated viable bacteria are dispersed in a solution or gel that can flow inside the sealing bag 10 in the viable cell storage unit 6, the end portion P1 of the solution or gel is the end portion. It flows to the P2 side, and the end P1 and the end P2 come into contact (see FIG. 2D).

  Thereby, it becomes possible to start giving and receiving of the growth correlation live bacteria between the culture medium 20 and the live bacteria storage unit 6. For this reason, the use time of the expiration date display label 2 can be adjusted by attaching and detaching the blocking unit 11.

  In addition, when the growth correlation live bacteria are pulverized and stored in the viable cell storage unit 6, the expiration date display label so that the powdered growth correlation live bacteria move to the end P2 side. 2 may be shuffled in the left-right direction with respect to the paper surface.

  According to the said structure, the sticker of the expiration date display label 2 can start giving and receiving of a growth correlation live microbe between the culture medium 20 and the live microbe accommodating part 6 by removing the prevention part 11. FIG. Become.

  For this reason, the use time of the expiration date display label 2 display label can be adjusted by attaching / detaching the lower end portion of the blocking portion 11 of the top film 10a from the adhesive portion 70.

(Adhesive part 70)
As described above, the adhesive part 70 is provided to partition the viable cell storage part 6 and the culture medium 20. The adhesive portion 70 is made of a low adhesive acrylic adhesive having a thickness of 10 μm.

  As shown in FIG. 2 (c), the adhesive portion 70 is formed by pulling the blocking portion 11 provided on the upper film 10 a in the direction indicated by the arrow C, whereby the adhesive layer 40 and the adhesive layer described later are used. Sealing property for preventing the growth-correlated viable bacteria sealed in the viable cell housing part 6 from adhering to the culture medium 20 is low-adhesive enough to easily peel off without peeling off 60. I just need it. The material is not particularly limited as long as it satisfies the above characteristics.

  According to the said structure, the sticker who sticks the expiration date display label 2 on food etc. can adhere the proliferation correlation living microbe to the culture medium 20 freely by pulling up the prevention part 11, and it proliferates before sticking. The effect that the sticker can easily set the attachment timing of the growth-correlated live bacteria without completing the growth of the live-correlated bacteria is obtained.

  The bottom film 10b, the adhesive layer 40, the backing sheet 50, and the adhesive layer 60 have the same structure as the expiration date display label 1, and the configuration is also the same, so the description thereof is omitted here.

[Embodiment 3]
In addition, the expiration date display labels 1 and 2 of the present embodiment include detection units that detect the progress (degree) of growth of the growth-correlated live bacteria in the culture medium 20, as shown in FIGS. 3 (a) and 3 (b). 74 and a transmission unit (passive contact authentication tag, detection unit) 7 for transmitting notification information regarding the degree of proliferation detected by the detection unit 74 may be provided. FIG. 3 shows an example in which the expiration date display label 1 is provided with the detection unit 74 and the transmission unit 7, but the same applies to the expiration date display label 2.

  As shown in FIG. 3 (b), the detection unit 74 has a structure in which the lead wire (detection unit) 72 from the transmission unit 7 is held in a disconnected state in the culture medium 20.

  With the above structure, in the state where the living bacteria are not growing, the lead wire 72 remains disconnected in the non-conductive agar, but the living bacteria grow to the cross-section ee, The carbon contained in the living bacteria becomes conductive. That is, the transmission part 7 and the whole detection part 74 become a conduction circuit, and the transmission part 7 is in a communicable state. In other words, in this embodiment, the transmitter 7 and the detection unit 74 as a whole exhibit a function as a detection unit.

  More specifically, the transmission unit 7 is in a state where transmission is possible, and the acquired notification information (or detection information) indicates that the detection unit 74 has detected the degree of growth of the growth-correlated live bacteria. In this case, it is considered that the degree of growth of growth-correlated live bacteria has been detected.

  As described above, as shown in FIG. 3, it is determined that the viable bacteria have grown to the best-before date position (= substantially the position of the lead wire 72), that is, that the best-before date has expired (the degree of growth). Can be detected.

  Note that the detection unit 74 is not limited to the above structure, and any structure that can detect that the growth of live bacteria has reached (or is approaching) the expiration date as shown in FIG. For example, since the reflectance of the surface of the culture medium 20 changes due to the growth of viable bacteria, a structure that can detect the reflection of light at the expiration date using an optical sensor or the like may be used. The structure which can detect that the proliferation of live bacteria has reached the expiration date position using a thermocouple or the like so that the heat to be detected can be detected.

  3A is configured, for example, as a passive RF tag of 13.56 MHz band, and includes an antenna unit 71, an IC (Integrated Circuit) unit 73, and a lead wire 72.

  Passive contactless authentication tags (passive RF (Radio Frequency) tags, passive radio ICs, passive IC tags) are different from active RF tags (active RF tags, active radio ICs, active IC tags). Since a battery is not required for operation, the product state can be confirmed even for a product with a long shelf life and a long service life. For example, if the passive RF tag is a 13.56 MHz band passive RF tag, a null point can be reduced when an RFID (Radio Frequency Identification) reader is provided in a refrigerator or the like to detect a product. The degree of freedom in installing the RFID reader is expanded.

  The antenna unit 71 only needs to receive and generate electric waves from an external RFID reader / writer (not shown), operate the IC unit 73, and transmit information to the RFID reader / writer. However, the antenna unit 71 is not limited to this form. is not. For example, when the growth of live bacteria reaches the expiration date position, the antenna unit 71 is disconnected in the IC unit 73 based on the result of the detection unit 74, and the information cannot be transmitted. Also good. More specifically, the notification information acquired when the transmitting unit 7 is ready to transmit indicates that the detection unit 74 has not detected the degree of growth of the growth-correlated viable bacteria, and the transmitting unit When the notification information is not acquired from 7, it may be considered that the degree of growth of the growth-correlated live bacteria has been detected.

  For example, the detection unit 74 may react with carbon dioxide generated by the growth of viable bacteria, and the antenna unit 71 may be corroded. In other words, any structure that can indicate a product whose expiration date has not expired to the RFID reader / writer together with the detection unit 74 may be used.

  The lead wire 72 only needs to be able to connect the detection unit 74 and the IC unit 73, but is not limited to this, and the detection unit 74 reacts to carbon dioxide generated by the growth of viable bacteria as described above, and the antenna unit. In the case of a structure that breaks 71 by corrosion, it is not necessary.

(Modification of detection unit 74)
Further, the detection unit 74 is configured to detect the degree of decrease in the conductivity of the antenna unit 71, and based on the detection result of the detection unit 74, the transmission intensity of the transmission unit 7 is adjusted to transmit the notification information. Anyway.

  In the configuration in which the antenna unit 71 corrodes due to the proliferation of viable bacteria as described above, even if the antenna unit 71 does not break in the IC unit 73, the conductivity of the antenna unit 71 is reduced due to the corrosion. Next, by detecting the degree of decrease in the conductivity by the detection unit 74 and adjusting the transmission intensity of the transmission unit 7 based on the detection result, the degree of growth of the growth-correlated live bacteria can be estimated from the outside. . That is, when the transmission intensity decreases, it can be determined that there is corrosion.

  The IC unit 73 only needs to receive power from the antenna unit 71, transmit power to the lead wire 72, receive a detection result from the detection unit 74, convert it into information, and transmit it to the antenna unit 71. However, the present invention is not limited to this, and the IC unit 73 is not required, and when the product that has not expired can be indicated on the RFID reader / writer together with the detection unit 74, the IC unit 73 What is necessary is just to be able to record and transmit various information (product name, manufacturer, date of manufacture, etc.) of the product.

  In FIG. 3, only one transmitting unit 7 is provided, but the number is not limited thereto, and another transmitting unit 7 may be further provided. That is, a plurality of transmitters 7 may be provided (see FIG. 4).

  According to the above structure, even when the transmitting unit 7 has a structure in which information cannot be transmitted due to the antenna unit 71 being disconnected based on the result of the detecting unit 74, the transmitting unit 7 is separated from another transmitting unit 7. It can be seen that there is a product by sending. That is, for example, it can be understood that there are unnecessary products in the refrigerator.

[Embodiment 4]
