Abstract
Description
[Technical field]
[0001] The present disclosure relates to a storage container for storing items whose quality deteriorates due to moisture. [Background technology]
[0002] Test materials (testing tools) used in measuring liquid samples such as blood and urine in clinical and self-testing are stored in a large number in dedicated test strip containers at medical institutions such as hospitals, testing institutions, or individual users who perform self-tests (hereinafter also referred to as test strip users). When using the test tools, the users take out the test tools one by one from the bottle in which they are stored, and use them as they are or supply them to a specified measuring device to test and measure the health condition, etc. of the liquid sample provider. The test tool is loaded with enzymes or compounds as reagents that are suited to the characteristics and purpose of the liquid sample to be measured. When the liquid sample is brought into contact with the test tool, the liquid sample reacts with the reagents loaded on the test tool and generates a chemical signal. By reading the signal visually or with a specified measuring device, it is possible to obtain qualitative or quantitative measurement results regarding the health condition of the liquid sample provider.
[0003] Reagents such as enzymes and compounds placed on the test tools have low humidity resistance, so there is a risk that they will deteriorate or denature when exposed to moisture. In addition, some test tools have a base material made of a material such as paper whose physical form changes significantly when it absorbs water. For these reasons, it is considered desirable to store the test tools in a dry space with low humidity. In addition, the quality assurance period of the test tools is generally determined on the premise that the test tools are stored in a dry space. Therefore, the test tools are usually stored in a bottle or aluminum pouch for storing the test tools, so that the space in which the test tools are stored is kept dry by placing a substance having a hygroscopic and drying effect inside the bottle or aluminum pouch for storing the test tools (for example, Patent Documents 1 and 2).
[0004] US Patent No. 5,399,663 relates to a method of storing and preserving moisture sensitive products such as diagnostic test strips, which discloses that an insert containing a desiccant component is secured inside the container body. US Patent No. 5,399,663 discloses a container for storing packaged articles such as test strips in a dry state, which discloses disposing a desiccant in the space containing the article. Furthermore, Patent Document 3 relates to a polymer composition containing zeolite, which has improved adsorption properties for substances such as water, and a method for producing the same, and discloses that the polymer can be used as a desiccant.

[0005] [Patent Document 1] Patent No. 7228566 [Patent Document 2] German published patent DE102014103565 [Patent Document 3] Special Publication No. 2022-526394 Summary of the Invention [Problem to be solved by the invention]
[0006] As described above, items whose quality deteriorates due to moisture are stored in containers with desiccants or the like placed inside in order to suppress deterioration of quality. However, among items whose quality deteriorates due to moisture, for example, test tools used in clinical and self-testing are usually used by a user who inserts his / her fingers into the container to remove them from the container every time a measurement / test is performed. Although the label of the container or the attached document of the contents (items contained in the container) includes precautions for removing test strips from the container, some users may not notice that moisture is attached to their fingers or palms (hereinafter, sometimes simply referred to as "hands"), and may insert their fingers into the container in that state to remove the test tool, resulting in moisture being attached to the inside of the container. In addition, some users may return unused test tools to the container after removing multiple test tools, and in that case, if moisture is attached to the user's hands, the moisture may adhere to the test tool, and the test tool with moisture attached may be returned to the container as it is. Although a desiccant or the like is placed inside the container, if moisture from hands gets mixed in, the desiccant may not be able to absorb the moisture sufficiently, or even if it does, the life of the desiccant may be shorter than the preset period. As a result, even if the container is stored in an appropriate environment, the quality of the testing tools inside the container may deteriorate, and appropriate measurement accuracy may not be obtained even within the period for which the manufacturer guarantees the quality.
[0007] Therefore, the present disclosure provides a container that can prevent liquid such as moisture from entering the inside of the container even if the liquid is on a user's hands when the user removes an item contained in the container from the container. [Means for solving the problem]
[0008] In one aspect, the present disclosure relates to a storage container for storing items whose quality deteriorates due to moisture, the storage container having at least one of a liquid-absorbing member that absorbs liquid and an indicator member that changes color upon contact with liquid on an outer surface of the container. Effect of the Invention
[0009] According to the container of the present disclosure, even if liquid such as moisture is present on the user's hands, the liquid can be prevented from entering the inside of the container. [Brief description of the drawings]

[Figure 6] FIG. 6 is a schematic diagram for explaining a storage container according to the second embodiment of the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] Products whose quality deteriorates due to moisture, such as clinical testing tools used in clinical and self-testing, are stored in containers filled with desiccants or the like to keep the containers dry, and a period for which the quality is guaranteed is set. This quality guarantee period is set on the premise that the environment inside the container is maintained under predetermined appropriate conditions. For this reason, the period during which the desiccants filled in the containers maintain their ability to sufficiently absorb liquids such as moisture also contributes to the determination of this quality guarantee period. For example, clinical testing tools such as urine test strips and biosensors used in blood tests, which are considered to deteriorate due to moisture, are stored in containers filled with desiccants and in an appropriate environment, and the period during which the quality of the testing tools is guaranteed when stored in such an environment is experimentally verified, and the information obtained therefrom is provided to medical institutions such as hospitals, testing institutions, and individuals who perform self-tests.
[0012] The present inventors have found that the causes of quality deterioration of an article contained in a container include not only opening and closing the container when taking out the article, but also moisture on the user's hands when taking out the article, and that the moisture may have a large influence. As described above, the package insert of the contents and the label of the container include instructions for taking out a test piece from the container, but some users may not notice that moisture (e.g., sweat, etc.) is on their hands, or even if they notice it, they may think that the amount of moisture is small and open the container and put their hands in the container to take out the article. While the desiccant placed in the container has a certain ability to adsorb moisture, etc., the adsorption of moisture, etc. is an irreversible process. In the environment where the user is located, it may not be possible to release moisture (regenerate the desiccant). For this reason, the present inventors have found a problem that had not been recognized before, that moisture on the hands gets mixed into the container, causing a large fluctuation in the storage environment (moisture content / humidity) inside the container, resulting in deterioration of the quality of the article contained inside and a shortened life of the desiccant. In order to solve this problem, the inventors have found that a liquid absorbing member that absorbs liquid and / or an indicator member that changes color when liquid comes into contact with the liquid is disposed on the outer surface of the storage container. By disposing these members on the outer surface of the storage container, even if a user does not notice that there is moisture on his / her hands or if he / she notices it but judges that the amount is small, the liquid absorbing member can absorb the moisture on the hand or can alert the user to the moisture before the user's hand enters the container, i.e., when the user touches the container. This makes it possible to prevent the moisture on the hand from being brought into the container or from adhering to the article contained in the container, and to suppress deterioration of the quality of the article contained in the container due to the moisture.
[0013] [Containment Container] In one aspect, the present disclosure relates to a storage container for storing items whose quality deteriorates due to moisture, the storage container having at least one of a liquid-absorbing member that absorbs liquid and an indicator member that changes color upon contact with liquid on an outer surface of the container.
[0014] The article to be stored in the storage container of the present disclosure is an article whose quality deteriorates due to moisture, and in one or more embodiments, examples thereof include an article whose shape cannot be maintained by contact with moisture, and an article whose measurement accuracy is reduced and cannot be used correctly (deteriorated in quality). In one or more embodiments, examples of the article include a test tool, a chemical test paper, and a humidity indicator card. In one or more embodiments, examples of the test tool include a clinical test tool. In one or more embodiments, examples of the clinical test tool include a biosensor that measures a measurement target in a sample, a urine test paper, and an immunochromatography test strip. In one or more embodiments, examples of the biosensor include a biosensor having a reagent layer containing an enzyme, and in one or more embodiments, examples of the biosensor include a conductive part and a reagent layer containing an oxidoreductase and an electron transfer substance. In one or more embodiments, examples of the chemical test paper include a pH test paper.
[0015] The storage container of the present disclosure is provided with at least one of a liquid absorbing member that absorbs liquid and an indicator member that changes color when it comes into contact with liquid, on the outer surface of the container. The "liquid" in these members is not particularly limited as long as it is a liquid that may adhere to the user's hands, and in one or more embodiments, examples of the liquid include body fluids such as sweat and tears, and water.
[0016] The location where the liquid absorbing member and / or the indicator member are arranged is not particularly limited as long as it is the outer surface of the container, and in one or more embodiments, examples of the location include a location on the outer surface of the container that a user may touch or is likely to touch when removing an item stored inside the container. In one or more particularly limited embodiments, when the storage container of the present disclosure includes a container body and an openable and closable lid, the outer surface of the container refers to a portion that a user can touch (a portion exposed to the outside) of the container with the lid closed. In one or more embodiments, the location where the liquid absorbing member and / or the indicator member are arranged may be the side surface of the container body, the bottom surface of the container body, the outer surface of the lid, etc. In one or more embodiments, the outer surface of the lid may be the upper surface of the lid, a protrusion (knob) provided on the lid, etc. In one or more embodiments, the location where the liquid absorbing member and / or the indicator member are arranged may be one location or multiple locations. In one or more embodiments, the storage container of the present disclosure includes a container body that stores an article inside and a lid that covers an opening of the container body and can be opened and closed. In one or more embodiments, the container body and the lid are connected via a hinge. In one or more embodiments, the lid may be provided with a knob (protrusion) for opening and closing the lid, and the knob is provided on the outer surface (edge) opposite to the position where the hinge is provided.
[0017] In the present disclosure, the term "liquid absorbing member that absorbs liquid" refers to a member having the ability (property) to absorb liquid such as water, and may be a member formed of a material having the ability to absorb liquid such as water. In one or more embodiments, the liquid absorbing member in the present disclosure is a member that can absorb moisture attached to the user's fingers when the user takes out an article stored inside the container. This makes it possible to prevent the user from taking out the article stored inside the container with moisture attached to the fingers, and to prevent moisture from being brought into the container. Since the liquid absorbing member is provided on the outer surface of the container, in one or more embodiments, the absorbed moisture can be released (dried) in the environment in which the container is stored, and therefore the container can be used repeatedly. In one or more embodiments, the liquid absorbing member may be provided in a removable state. This makes it possible to easily replace the liquid absorbing member with another new liquid absorbing member after absorbing moisture.
[0018] In one or more embodiments, the liquid absorbing member is composed of a base and a liquid absorbing material, and may be one in which the liquid absorbing material is disposed on the base, or one formed of a resin material obtained by mixing the liquid absorbing material with a resin. In one or more embodiments, the liquid absorbing member only needs to have an ability (property) to absorb liquid in the exposed portion when placed in the container, and the inside of the liquid absorbing member does not need to have an ability (property) to absorb liquid.
[0019] In one or more embodiments, the liquid absorbing material may be a porous material, a hydrophilic fiber, a foam material, or other water-absorbent material. In one or more embodiments, the porous material may be diatomaceous earth, zeolite, charcoal, silica gel, or the like. In one or more embodiments, the hydrophilic fiber may be natural fiber or chemical fiber. In one or more embodiments, the natural fiber may be cotton or wool, or the like, and in one or more embodiments, the chemical fiber may be rayon, cupra, acetate, polyurethane, polyester, or the like. In one or more embodiments, the foam material may be foam sponge or urethane foam. In one or more embodiments, the liquid absorbing material may be disposed on the substrate surface by coating, pasting, covering, embedding, or the like.
[0020] In one or more embodiments, the liquid absorbing member may contain a water-repellent substance or a substance that has been treated to be water-repellent. However, in order to avoid impairing the liquid absorption ability, it is preferable that the surface that comes into contact with the user (e.g., the exposed surface of the liquid absorbing member) does not contain a water-repellent substance or a substance that has been treated to be water-repellent.
[0021] In one or more embodiments, the "indicator member that changes color when it comes into contact with liquid" in the present disclosure is a member that can change color in response to moisture on the user's fingers when the user takes out an item stored inside the container. This can alert the user that moisture is on the user's fingers and prevent moisture from being brought into the container. In one or more embodiments, "changing color" in the present disclosure can include a change in hue and a change in brightness, as well as a combination of these. The change in color is not particularly limited as long as it is a change caused by contact with moisture, and in one or more embodiments, examples of the change in color include a color change in which the color develops when it gets wet and disappears when it dries, a color change in which the color disappears when it gets wet and develops color when it dries, a color change in which the color changes when it gets wet and returns to its original color when it dries, and a color change in which the color of the upper layer changes when it gets wet, allowing the color of the lower layer to be confirmed, and when it dries, the upper layer returns to its original color, making it impossible to confirm the color of the lower layer. The change in color tone may include, in one or more embodiments, a color change due to a mechanism in which the indicator member has a two-layer structure, and when wetted with water, the color of the lower layer does not change, but the light transmission method of the upper layer (the layer that serves as a screen) changes, for example becoming transparent, so that the color of the lower layer can be visually confirmed. In one or more embodiments, it is preferable that the indicator member is capable of reversibly changing color tone.
[0022] In one or more embodiments, the indicator member is composed of a color-changing substance and a substrate. In one or more embodiments, the color-changing substance may be impregnated into the substrate or applied to the substrate surface. In one or more embodiments, examples of the color-changing substance include substances that change color in response to moisture, such as lithium compounds, cobalt compounds, organic dyes, and low-refractive-index pigments. In one or more embodiments, examples of the low-refractive-index pigment include particulate silica.
[0023] The shape of the container is not particularly limited, and in one or more embodiments, examples of the shape include a cylindrical shape, a square prism shape, etc. In one or more embodiments, examples of the material of the container include known materials used for containers that store items whose quality deteriorates due to moisture.
[0024] In one or more embodiments, in addition to the item whose quality deteriorates due to moisture, a desiccant (moisture absorbent) capable of absorbing moisture in the container may be placed in the storage container of the present disclosure. In one or more embodiments, examples of the desiccant include silica gel, calcium chloride, lime, and zeolite.
[0025] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the present disclosure is not limited to these embodiments.
[0026] <First embodiment> 1 is a perspective view showing the appearance of a measuring device 1 in the first embodiment. The measuring device 1 is portable and is used to electrochemically analyze a test substance in a sample using a biosensor 2. One example of the measuring device 1 in this embodiment is a blood glucose measuring device that is configured to have a function for detecting the blood glucose level (glucose concentration) in blood.
[0027] As shown in FIG. 1, the measurement device 1 includes a main body 1a. The main body 1a includes an insertion port 1b for inserting a strip-shaped biosensor 2, a display unit 1c for displaying measurement data, and a disposal mechanism (not shown) for removing the biosensor 2. The disposal mechanism is provided on the surface opposite the display unit 1c (the back surface of the main body 1a). One side of the main body 1a includes a connector 1d for data communication with an external device. The measurement device 1 can transmit and receive data such as measurement data, measurement time, and patient ID to and from an external device such as a mobile device such as a smartphone or a personal computer via the connector 1d. The main body 1a includes a plurality of operation buttons (not shown).
[0028] The biosensor 2 is a biosensor for measuring blood glucose levels. As shown in FIG. 1, the biosensor 2 is formed with a sample supply port 2d and an air hole 2e. The sample supply port 2d is connected to a flow path provided in the biosensor 2, and the air hole 2e is provided to exhaust air in the flow path caused by a sample being supplied from the sample supply port 2d into the flow path. The flow path of the biosensor 2 is provided with a conductive part including an electrode pair having a working electrode and a counter electrode, and a reagent layer on the conductive part. Examples of the reagent disposed in the reagent layer include an electron transfer substance (such as a ruthenium complex such as Ru(NH3)6Cl3) and an oxidoreductase (such as glucose oxidase (GOD) or glucose dehydrogenase (GDH)).
[0029] 2 to 4 are schematic diagrams for explaining the storage container 30 in the first embodiment. The storage container 30 in the first embodiment can store a plurality of rectangular biosensors 2 therein. Fig. 2 shows a state in which the lid 32 is closed, and Fig. 3 shows a state in which the lid 32 is opened to expose the opening of the container body 31. Fig. 4 is a cross-sectional view of the state in which the lid 32 is closed.
[0030] The storage container 30 has a container body 31 and a lid 32, and the container body 31 and the lid 32 are connected via a hinge 34. The container body 31 is cylindrical and has an opening at its upper end. A space 37 for disposing a desiccant such as silica gel is provided on the bottom side of the container body 31. A partition plate 36 having a plurality of through holes is provided at the upper part of the space 37, and a plurality of biosensors can be disposed in the space above the partition plate 36. The partition plate 36 allows the moisture in the storage container 30 to be absorbed by the desiccant without direct contact between the biosensor and the desiccant, thereby keeping the inside of the storage container 30 dry.
[0031] The lid 32 is disk-shaped and can seal the opening at the upper end of the container body 31. The lid 32 can rotate upward with respect to the opening of the container body 31 around a hinge 34, and the opening of the container body 31 is opened by rotating the lid 32 upward. The lid 32 is fitted to the periphery of the opening of the container body 31 by a fitting structure such as a concave-convex shape, so that when the lid 32 is closed, the opening of the container body 31 is sealed, and the container 30 is configured to be in an airtight state in which no outside air can enter the inside of the container 30. An outward protrusion (grip 33) is provided on the side of lid 32 at a position diagonally opposite the side on which hinge 34 is provided, and the user can hold this grip 33 with the fingers of one hand while supporting container body 31 with the fingers of the other hand, and rotate it in this state to open lid 32. Alternatively, lid 32 can be opened with one hand by pushing up grip 33 with the fingers.
[0032] Liquid absorbing members 35a, 35b are attached to the upper and lower surfaces of knob portion 33 provided on lid 32. As a result, even if moisture is present on the user's fingers when removing the biosensor from storage container 30, the moisture can be absorbed by liquid absorbing members 35a, 35b by touching liquid absorbing members 35a, 35b of knob portion 33 to open lid 32, thereby preventing moisture from entering inside container body 31 when removing the biosensor.
[0033] The liquid absorbing members 35a and 35b each include a base and a liquid absorbing material, such as diatomaceous earth or zeolite, disposed on the surface of the base. Alternatively, the liquid absorbing members 35a and 35b may each have a base itself formed of a liquid absorbing material.
[0034] An adhesive layer may be provided on one of the main surfaces of the base, on the adhesive surface with the grip portion 33, so that the liquid absorbing members 35a, 35b may be in the form of a seal that can be removed from the grip portion 33. This allows the liquid absorbing members 35a, 35b to be easily replaced periodically. The liquid absorbing members 35a, 35b may be coated with a substance that changes color when liquid comes into contact with them, or the liquid absorbing material may be coated on a base impregnated with a substance that changes color when liquid comes into contact with it. This allows the user to recognize that moisture is attached to the fingers, and to easily know that moisture has been absorbed by the liquid absorbing members 35a, 35b. This allows the liquid absorbing members 35a, 35b to be replaced at the timing when moisture is absorbed.
[0035] In this embodiment, the members 35a, 35b provided on the upper and lower surfaces of the grip portion 33 are liquid-absorbing members, but the present disclosure is not limited to this embodiment, and the members 35a, 35b may be indicator members that change color when liquid comes into contact with them. By providing an indicator member on the grip portion 33, the user can easily recognize that moisture is on his or her fingers, and the user can be alerted, thereby reducing the risk of moisture entering the container body 31.
[0036] <Second embodiment> 5 is a schematic diagram for explaining a storage container 40 in the second embodiment. The storage container 40 in this embodiment has a cylindrical container body 41 and a disk-shaped lid 42 that can seal the opening at the upper end thereof, and the container body 41 and the lid 42 are connected via a hinge 44. The lid 42 has a knob portion 43. The storage container 40 in this embodiment is different in that an indicator member 45 is provided on the side surface of the container body 41 instead of the liquid absorbing members 35a, 35b provided on the knob portion 33, and the other configurations are the same as the storage container 30 in the first embodiment.
[0037] As described above, in storage container 40 of the present embodiment, indicator member 45 is provided on the side surface of container body 41. With this, even if moisture is on the user's fingers when removing the biosensor from storage container 40, the user can be alerted to the fact that moisture is on the fingers by touching indicator member 45 provided on the side surface of container body 41 to open lid 42, thereby reducing the risk of moisture entering container body 41.
[0038] The indicator member 45 may be a base such as paper impregnated with a substance that changes color when liquid comes into contact with it, or a base surface printed with a substance that changes color when liquid comes into contact with it. The indicator member 45 may be provided on the entire side surface of the container body 41, or may be provided on a portion of the side surface of the container body 41. The indicator member may also be provided on a portion of a label attached to the side surface of the container body 41.
[0039] In this embodiment, the member 45 provided on the side of the container body 41 is an indicator member, but the present disclosure is not limited to this embodiment, and the member 45 may be a liquid absorbing member. By providing a liquid absorbing member on the side of the container body 41, even if moisture is attached to the user's fingers when removing the biosensor from the storage container 40, the attached moisture can be absorbed by touching the liquid absorbing member 45 provided on the container body 41, thereby preventing the intrusion of moisture into the container body 41 when removing the biosensor. The liquid absorbing material may be provided on the entire surface of the member 45 provided on the side of the container body 41, or the liquid absorbing material may be provided on a part of the member 45.
[0040] Furthermore, together with the member 45 provided on the side surface of the container body 41, an indicator member and / or a liquid absorbing member may be provided on the upper and / or lower surface of the knob portion 43, as in the first embodiment.
[0041] <Third embodiment> 6A and 6B are schematic diagrams for explaining a storage container 50 in the third embodiment. The storage container 50 in this embodiment has a cylindrical container body 51 and a disk-shaped lid 52 capable of sealing the opening at the upper end thereof, and the container body 51 and the lid 52 are connected via a hinge 54. The lid 52 has a knob portion 53. The storage container 50 in this embodiment is different in that liquid absorbing members 55a, 55b are provided on the upper surface of the lid 52 and the bottom surface of the container body 51, respectively, instead of the knob portion 53, and the other configurations are the same as the storage container 30 in the first embodiment.
[0042] As described above, in the storage container 50 of this embodiment, liquid absorbing members 55a, 55b are attached to the upper surface of the lid 52 and the bottom surface of the container body 51, respectively. The upper surface of the lid 52 and the bottom surface of the container body 51 are frequently touched by a user when removing a biosensor from the storage container 50, and the biosensor stored in the container is often removed with fingers that have touched the upper surface of the lid 52 and the bottom surface of the container body 51. Therefore, even if moisture is attached to the user's fingers when removing the biosensor, the moisture can be efficiently prevented from entering the inside of the container body 51.
[0043] The liquid absorbing members 55a and 55b may be coated with a substance that changes color when liquid comes into contact with them, or may be coated with a liquid absorbing material on a substrate impregnated with a substance that changes color when liquid comes into contact with it. This allows the user to recognize that moisture is on the fingers, and to easily know that moisture has been absorbed by the liquid absorbing members 55a and 55b. Therefore, the liquid absorbing members 55a and 55b can be replaced when the moisture is absorbed.
[0044] In this embodiment, the members 55a and 55b provided on the upper surface of the lid 52 and the bottom surface of the container body 51 are liquid absorbing members, but the present disclosure is not limited to this embodiment, and the members 55a and 55b may be indicator members that change color when liquid comes into contact with them. By providing indicator members on the upper surface of the lid 52 and the bottom surface of the container body 51, the user can easily recognize that moisture is attached to his or her fingers, and can efficiently alert the user. This effectively reduces the risk of moisture entering the container body 51.
[0045] In addition to members 55a, 55b provided on the upper surface of lid 52 and the bottom surface of container body 51, an indicator member and / or liquid absorbing member may be provided on the upper and / or lower surface of knob portion 53, as in the first embodiment.
