Description

  The present invention relates to a technique of a packaging body in which a plurality of packaging objects that need moisture prevention are accommodated.

  When a product is affected by humidity in the air and has a property of losing its original function, the packaging method is important in order to preserve the product for a long time while maintaining its quality. Examples of products that are easily affected by humidity include measuring tools (eg, test pieces, enzyme sensor chips). Such measuring tools are used in fields such as clinical examinations and food quality control for the purpose of detecting specific substances in body fluids such as blood and specimens such as foods. Since such a measuring tool usually contains a dry reagent that easily deteriorates due to moisture in the air, it is preferable that the measuring tool is individually stored individually by packaging from the viewpoint of maintaining quality.

  For example, in Patent Document 1, a measurement tool is sandwiched between an upper packaging film as an upper member and a lower packaging film as a lower member, and the peripheral portions of the upper packaging film and the lower packaging film are sealed. Thus, a package in which the measurement tool is individually packaged is described.

  When such a package is stored, a plurality of packages are often stored together. Conventionally, various methods have been adopted to store a plurality of packages. For example, in patent document 2, the method of accumulating a some package in the vertical direction and accommodating in a storage case is taken.

  Patent Document 3 describes a package in which a measuring tool is accommodated in a chamber formed in a resin storage container as a lower member, and the periphery of the chamber is sealed with a sealing foil as an upper member. In the package, the measurement tools are individually stored one by one. The storage container has a shape in which the plurality of packaging bodies are connected in the lateral direction, so that the plurality of packaging bodies can be stored together.

  However, in the prior art, there are points to be improved as described below.

  That is, in the package described in Patent Document 1 or Patent Document 3, it is necessary to provide an upper member and a lower member for each measurement tool. Therefore, when a plurality of individually wrapped measuring tools are stored together, the amount of members used is increased, resulting in a problem of increased manufacturing costs. Moreover, due to the large amount of members used, there was a problem that the compactness during storage was lacking.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

<First Embodiment>
With reference to FIGS. 1-5, the structure of the package 1 which concerns on the 1st Embodiment of this invention is demonstrated. The package 1 is carried by a diabetic patient or placed in a ward, and is used to easily measure a patient's blood sugar. As shown in FIG. 1, the package 1 includes a packaging material 2 and a blood glucose measurement sensor 3. In the following description, directions such as the up and down direction are as described in the drawings. In addition, numerical ranges indicated using “to” indicate ranges including the numerical values described before and after “to” as the minimum value and the maximum value, respectively.

  As shown in FIG. 1 and FIG. 2 (A), the packaging material 2 is a bag for packaging a plurality of blood glucose measurement sensors 3. The outer shape of the packaging material 2 is a rectangle. The packaging material 2 individually packages a plurality of blood glucose measurement sensors 3 one by one (packaging individually), and stores them integrally in a stacked state. As shown in FIG. 1, the packaging material 2 includes a housing part 20, a sealing part 21, and an opening tab part 22. In addition, the external shape of the packaging material 2 is not restricted to a rectangle, For example, a round shape and a square may be sufficient.

  The accommodating portion 20 is a portion for individually accommodating the blood glucose measurement sensors 3 one by one. The sealing portion 21 is formed around the housing portion 20 and is a portion for defining the housing portion 20 and the outside of the packaging material 2. The sealing unit 21 prevents the dry reagent contained in the blood glucose measurement sensor 3 from being exposed to external moisture, and prevents performance deterioration. As shown to FIG. 2 (A), in the packaging material 2, the some accommodating part 20 is piled up and down. Each of the plurality of blood glucose measurement sensors 3 is individually and stacked and accommodated in a plurality of accommodation units.

  As shown in FIGS. 2A and 2B, the packaging material 2 includes a plurality of types of packaging films 23, 24, and 23A. The blood glucose measurement sensor 3 is sandwiched between the packaging film 23 and the packaging film 24, between the packaging film 24 and the packaging film 24, and between the packaging film 24 and the packaging film 23A. That is, in the package 1, the blood glucose measurement sensor 3 and the packaging films 23, 24, and 23A are alternately stacked. Around the blood glucose measurement sensor 3, the upper surface of the packaging film 24 adjacent to the lower surface of the packaging film 23, the upper surface of the packaging film 24 adjacent to the lower surface of the packaging film 24, or the upper surface of the packaging film 23A adjacent to the lower surface of the packaging film 24 Are bonded to each other to form a plurality of storage portions 20 and a plurality of sealing portions 21, and each of the plurality of blood glucose measurement sensors 3 is enclosed in each of the plurality of storage portions 20. The thickness of the accommodating part 20 is 0.1 mm-2.0 mm, 0.1 mm-1.0 mm, or 0.2 mm-0.6 mm, for example.

  As shown in FIGS. 1, 2 </ b> A, and 2 </ b> B, the opening tab portion 22 is provided at the end of the package 1. As shown well in FIG. 2A, the package 1 is, for example, rectangular. The opening tab 22 is provided so as to protrude from one side of the peripheral portion 21 a of the sealing portion 21 in the short direction. The opening tab portion 22 is formed by protruding each of the plurality of packaging films 23, 24, and 23A beyond the plurality of laminated sealing portions 21. Each of the plurality of opening tabs 22 is stacked on each other without being bonded to each other. The package 1 is configured to be opened by an easy peel. Easy peel is a packaging technique that allows the packaging films 23, 24, and 23A adhered to each other to be easily peeled from each other at the time of opening, while maintaining the sealing performance of the housing portion 20 during storage. In the package 1, specifically, the sealing part 21 is comprised so that it can peel easily. The opening tab portion 22 functions as a peeling trigger portion for first picking when the user opens the package 1 and takes out the blood glucose measurement sensor 3.

  As shown in FIGS. 2 (A) and 2 (B), a packaging film 23 is used at the top of the packaging material 2. Specifically, for example, an aluminum laminate film is used as the packaging film 23. The packaging film 23 has, for example, the configuration shown in FIG. That is, the packaging film 23 is a multilayer film in which a PET (polyethylene terephthalate) film layer 23a, an aluminum layer 23b, a PET film layer 23c, and an easy peel film layer 23d are laminated in this order from the uppermost layer to the lowermost layer.

  The packaging film 23 is produced, for example, by bonding these films by a dry laminating method. An adhesive layer (not shown) is provided by diluting the adhesive for dry laminating to an appropriate viscosity with an organic solvent and applying it to the film. For example, the adhesive layer is selected from two-component curable urethane adhesive, polyester urethane adhesive, polyether urethane adhesive, acrylic adhesive, polyester adhesive, polyamide adhesive, and epoxy adhesive. Can be used.

  The uppermost PET film layer 23a has a role as a base material. Printing is performed on the PET film layer 23a. The characteristic of PET film is that it has excellent heat resistance and cold resistance. Due to the excellent heat resistance, when the PET film layer 23a is used as the uppermost layer, the laminate film has a wide heat seal temperature range and can be sealed cleanly.

  In addition, it is not restricted to PET that is suitable as a base material. For example, polyester films such as PEN (polyethylene naphthalate) and PBT (polybutylene terephthalate) and polyolefin films such as PE (polyethylene) and PP (polypropylene) can also be used as the substrate. In addition, PA (polyamide film) such as nylon-6 and nylon-66, PS (polystyrene film), PC (polycarbonate film), PAN (polyacrylonitrile film), PI (polyimide film), PVA (polyvinyl alcohol) , PVDC (polyvinylidene chloride). The thickness of the substrate is, for example, in the range of 0.01 mm to 0.05 mm or 0.01 mm to 0.03 mm.

  An aluminum layer 23b is provided on the lower surface of the PET film layer 23a. The aluminum layer 23b is a layer formed using an aluminum foil, and is provided for the purpose of improving the oxygen gas barrier property and the water vapor barrier property of the packaging film 23. As long as the aluminum foil has a thickness exceeding 30 μm, neither gas nor water vapor passes.

  The aluminum layer 23b is not limited to one using an aluminum foil. The layer formed by vapor-depositing aluminum on the PET film layer 23a as the base material can also be used as the aluminum layer 23b in the packaging film 23. In order to improve the oxygen gas barrier property and the water vapor barrier property, for example, an inorganic oxide vapor deposition film, an EVOH (ethylene / vinyl alcohol copolymer) film, or a PVDC (vinylidene chloride) film is used instead of the aluminum layer 23b. be able to. As the inorganic oxide, for example, silicon oxide, aluminum oxide, or magnesium oxide can be used.

  A PET film layer 23c is provided as an intermediate layer on the lower surface of the aluminum layer 23b. The thickness of this intermediate layer is, for example, in the range of 0.01 mm to 0.05 mm or 0.01 mm to 0.03 mm. The intermediate layer is provided for the purpose of improving the strength against dropping or piercing. As a material, for example, a polyamide film can be used in addition to PET.

  An easy peel film layer 23d is formed on the lower surface of the PET film layer 23c. The easy peel film layer 23d can be any of a cohesive failure type, an delamination type, and an interfacial peel type as an easy peel sealant layer. As the easy peel film layer 23d, for example, a cohesive failure type is adopted. The thickness of the easy peel film layer 23d is, for example, 0.005 mm to 0.06 mm, 0.01 mm to 0.06 mm, or 0.03 mm to 0.06 mm. Further, the peel strength of the easy peel film layer 23d is set in a range of, for example, 5N to 40N / 15mm, 5N to 30N / 15mm, 5N to 20N / 15mm, 5N to 10N / 15mm, or 6N to 8N / 15mm. .

  The cohesive failure type is a type in which the sealing portion 21 formed by the easy peel film layer 23d is peeled from the packaging material 2 while being destroyed (cohesive failure). As the material, for example, so-called “hot melt” in which EVA (ethylene-vinyl acetate copolymer) and wax are the main components and a tackifier such as rosin or terpene resin is added is used. Also, PE (polyethylene), HDPE (high density polyethylene), and LLDPE (linear low density polyethylene) may be used. In addition, a resin in which a polyolefin resin such as PE (polyethylene) and PB-1 (polybutene-1 resin) are mixed, a resin in which a polyolefin resin and polystyrene resin are mixed, and the like are used. The cohesive failure type easy peel film layer 23d is formed by adhering films prepared using these resins or applying a coating solution of these resins.

  When the delamination type is employed, the easy peel film layer 23d is composed of a multilayer film having at least two layers. These layers are produced, for example, by a coextrusion method. One of those layers is a sealing layer that is welded to the adjacent packaging film. The other layer is a release layer adjacent to the sealing layer. When the package 1 is opened, no peeling occurs between the adjacent packaging film and the sealing layer of the easy peel film layer 23d. The packaging film 23 is peeled off from the packaging material 2 while causing an interface failure or a cohesive failure between the seal layer and the release layer. For example, the release layer is formed using LLDPE as a material. Moreover, a sealing layer is formed using PP, PE, A-PET (amorphous polyethylene terephthalate) according to the material of the adhesive surface of an adjacent packaging film, for example. A characteristic of the delamination type is that the delamination strength is determined by the delamination strength in the easy peel film layer 23d, so that it is always constant regardless of the welding conditions.

  The interface peeling type is a type in which the packaging film 23 and the adjacent packaging film are peeled off at the welding interface. For example, PP (polypropylene) can hardly be fused with PE (polyethylene), but both can be welded by blending PE and PP or using PE with a special molecular structure. . Therefore, the easy peel film layer 23d needs to be set according to the material of the adhesive surface of the adjacent packaging film. By appropriately controlling this principle, an easy peel film layer 23d having a desired peel strength can be formed. For example, EVA (ethylene-vinyl acetate copolymer) can be used as a raw material for the interfacial peeling type easy peel film layer 23d. When using EVA, the film produced using the resin in which the mixing ratio of vinyl acetate is adjusted is laminated to produce the packaging film 23.

  As shown in FIGS. 2 (A) and 2 (B), a packaging film 24 is used at an intermediate portion between the uppermost portion and the lowermost portion of the packaging material 2. Specifically, an aluminum laminate film is used as the packaging film 24, similarly to the packaging film 23. The packaging film 24 has, for example, the configuration shown in FIG. In the packaging film 24, the same code | symbol is attached | subjected to the component which has the same or similar function as the packaging film 23. FIG. Detailed description of these will be omitted. Here, the packaging film 24 is different from the packaging film 23 in that an easy peel film layer 24e is provided as the uppermost layer. That is, the packaging film 24 is different from the packaging film 23 in that it has easy peel film layers 23d and 24e on both the uppermost layer and the lowermost layer.

  When assembling the package 1 with the configuration shown in FIG. 2 (B), the lower surface 23f of the packaging film 23 is formed at the top of the package 1 as shown in FIGS. 3 (A) and 3 (B). It is bonded to the upper surface 23g of the film 24 to form an easy peel adhesive layer. More specifically, the easy peel film layer 23 d of the packaging film 23 is thermally welded to the easy peel film layer 24 e of the packaging film 24. Moreover, in the intermediate part of the package 1, as can be understood from FIG. 3B, the lower surface 23h of the packaging film 24 is bonded to the upper surface 23g of the packaging film 24 adjacent below to form an easy peel adhesive layer. Is done. More specifically, the easy peel film layer 23d of the packaging film 24 is thermally welded to the easy peel film layer 24e of the packaging film 24 adjacent below.

  As shown in FIGS. 2A and 2B, a packaging film 23 </ b> A is used at the bottom of the packaging material 2. Specifically, for example, an aluminum laminate film is used as the packaging film 23A. The packaging film 23A has, for example, the configuration shown in FIG. That is, the packaging film 23A is a multilayer film in which an easy peel film layer 23d, a PET film layer 23c, an aluminum layer 23b, and a PET film layer 23a are laminated in this order from the top layer to the bottom layer. In the packaging film 23A, components having the same or similar functions as those of the packaging film 23 are denoted by the same reference numerals. Here, the packaging film 23A includes the same constituent elements as the packaging film 23, but the arrangement order of the constituent elements is merely reversed. Therefore, the detailed description is omitted for the description of each component.

  Therefore, as is apparent from FIGS. 3B and 3C, the lower surface 23h of the packaging film 24 is bonded to the upper surface 23j of the packaging film 23A adjacent to the lower portion at the lowermost portion of the package 1, An easy peel adhesive layer is formed. More specifically, the easy peel film layer 23d of the packaging film 24 is heat-welded with the easy peel film layer 23d of the packaging film 23A adjacent below.

  FIG. 3D shows a packaging film 24 </ b> A as a modification of the packaging film 24. In the packaging film 24A, the same reference numerals are given to components having the same or similar functions as the packaging film 24, and detailed description thereof is omitted here. The packaging film 24A is different from the packaging film 24 in that the uppermost layer includes a PE film layer 24Aa. When the packaging film 24A is used in the intermediate portion of the packaging body 1, the easy peel film layer 23d of the packaging film 23 is thermally welded to the PE film layer 24Aa of the packaging film 24A. Similarly, in the middle part of the package 1, the easy peel film layer 23 d of the packaging film 24 </ b> A is thermally welded to the PE film layer 24 </ b> Aa of the packaging film 24 </ b> A adjacent below. On the other hand, in the lowest part of the package 1, the easy peel film layer 23d of the packaging film 24A is heat-welded with the easy peel film layer 23d of the adjacent packaging film 23A. Thus, when using the packaging film 24A when manufacturing the package 1, the easy peel film layer 23d and the PE film layer 24Aa are thermally welded to each other except the bottom.

  An example of the blood glucose measurement system MS including the package 1 is shown in FIG. As shown in FIG. 4, the blood glucose measurement system MS includes a blood glucose measurement device 4 in addition to the package 1. The blood glucose measurement system MS is of a size that can be carried in a bag or the like. The blood glucose meter 4 is for simply measuring a blood glucose level in blood collected from a patient using the blood glucose measurement sensor 3. The blood glucose meter 4 includes a main body 40. The main body 40 has an insertion port 41 for inserting the blood glucose measurement sensor 3 and a liquid crystal display unit 42. The blood glucose measurement sensor 3 taken out from the package 1 is inserted into the insertion port 41 in the direction indicated by N1.

  The main body 40 includes a measurement unit (not shown) for measuring a blood glucose level, a storage unit (not shown), and a control unit (not shown). The measurement unit supplies a predetermined voltage signal to the blood glucose measurement sensor 3 inserted into the insertion port 41, receives the voltage signal indicating the measurement result output from the blood glucose measurement sensor 3, and performs AD conversion on the measurement data. Is generated. The control unit converts the measurement data obtained by the measurement unit into a blood glucose level based on a calibration curve stored in the storage unit, associates the blood glucose level with a measurement date, patient ID, and the like, Store in the department. Moreover, the said control part displays the blood glucose level and the data linked | related with it on the liquid crystal display part 42 as needed.

  The blood glucose measurement sensor 3 is configured to be able to inhale a patient's blood (whole blood), and has a function of detecting a blood glucose level. The blood glucose measurement sensor 3 corresponds to an example of an object to be packaged in the present invention, and also corresponds to an example of a measurement tool. Furthermore, the blood glucose measurement sensor 3 corresponds to an example of a biosensor in the present invention. As shown in FIGS. 5A and 5B, the blood glucose measurement sensor 3 includes a substrate 30, a spacer 31, and a cover 32.

  The substrate 30 is formed using, for example, a synthetic resin having hydrophobicity. On the substrate 30, four signal wirings 30a, 30b, 30c, and 30d are formed. These signal wirings 30a, 30b, 30c, and 30d are formed in a predetermined pattern by screen printing using, for example, carbon ink. The signal wirings 30a, 30b, 30c, and 30d are connected to electrode portions 30e, 30f, 30g, and 30h provided in front of the substrate 30, respectively. A connector (not shown) having contacts that contact the four signal wires 30a, 30b, 30c, and 30d is provided in the back of the insertion port 41 of the blood glucose meter 4. This connector is for connecting the four signal wires 30a, 30b, 30c, 30d and the measuring section.

  As shown in FIG. 5B, a resist 33 is formed in a predetermined pattern on the substrate 30 and the signal wirings 30a, 30b, 30c, and 30d by screen printing. Specifically, the resist 33 is formed so that the electrode portions 30e, 30f, 30g, and 30h are exposed. The resist 33 is formed so that part of the signal wirings 30a, 30b, 30c, and 30d is exposed behind the substrate 30. The resist 33 is formed for the purpose of insulation using thermosetting ink or the like.

  As shown in FIGS. 5A and 5B, a spacer 31 is provided on the resist. The spacer 31 also has a function as an adhesive layer for bonding the substrate 30 and a cover 32 described later. The spacer 31 bonds the substrate 30 and the cover 32 to each other via a resist 33 formed on the substrate 30. The spacer 31 is formed using a double-sided tape, for example. By punching the spacer 31, an introduction hole 31a and a flow path 31b for blood collected from the patient are formed between the substrate 30 and the cover 32. Further, the flow path 31b is formed so that the electrode portions 30e, 30f, 30g, and 30h are exposed therein. The introduction hole 31 a is formed at the front end of the blood glucose measurement sensor 3. The blood collected from the patient is sucked from the introduction hole 31a in the direction indicated by the arrow N2, and is introduced into the channel 31b by capillary action. The volume of the flow path 31b is formed to be, for example, 0.1 to 10 μL, 0.15 to 5 μL, or 0.25 to 3.5 μL.

  A cover 32 is bonded to the upper surface of the spacer 31. By adhering the cover 32, the flow path 31b becomes a capillary tube. In order to facilitate the capillary action, the cover 32 is provided with an air hole 32a. As a material of the cover 32, for example, a synthetic resin having hydrophilicity is used.

  As shown in FIG. 5B, in the flow path 31b, a pair of hematocrit electrodes 30j including electrode portions 30e and 30f are provided on the introduction hole 31a side. A pair of glucose electrodes 30k including electrode portions 30g and 30h are provided on the back side of the pair of hematocrit electrodes 30j. A solidified dry reagent 34 is placed on the pair of glucose electrodes 30k. The dry reagent 34 includes, for example, an oxidoreductase and a mediator as a blood glucose measurement reagent. The dry reagent 34 contains, for example, glucose oxidase or glucose dehydrogenase as an oxidoreductase. Further, the dry reagent 34 includes, for example, a quinone compound, potassium ferricyanide, phenazine methosulfate, methylene blue, ferrocene, phenothiazine, a ruthenium complex, or a derivative thereof as a mediator. For example, the dry reagent 34 is likely to deteriorate due to the influence of moisture contained in the air, and therefore, it is preferable to employ a storage method that can strictly maintain the dry state. Therefore, it is desirable to store the blood glucose measurement sensor 3 by individual packaging.

  The pair of hematocrit electrodes 30j is configured so that the blood glucose meter 4 supplies an AC or DC voltage signal to the signal wirings 30a and 30b in a state where blood is in contact with the electrode portions 30e and 30f, thereby obtaining a hematocrit value. Used to detect. The pair of glucose electrodes 30k is connected to the signal wires 30c and 30d in a state where the blood glucose meter 4 is in contact with the electrodes 30g and 30h and the dry reagent 34 and reacts with the dry reagent 34. It is used to detect the glucose level (blood glucose level) by supplying a DC voltage signal. The blood glucose meter 4 corrects the blood glucose level to an appropriate value according to the obtained hematocrit value.

  Note that the packaging object of the package 1 is not limited to the blood glucose measurement sensor 3. For example, a biosensor that measures a substance other than glucose contained in blood, such as a lactic acid sensor or a cholesterol sensor, can be used as a packaging object.
