Description

  The present invention relates to a container for storing a plate-shaped product such as a blood glucose level sensor or a urine test paper, and more particularly to a plate-shaped product storage container having a drying property to prevent moisture absorption of the plate-shaped product. .

Conventionally, plate-like products such as blood glucose level sensors and urine test strips are deteriorated due to moisture absorption and deteriorate in performance, so they are stored and stored in a container having a drying property.
As a container having such a drying property, a container main body having a cylindrical body part and a bottom part, and a lid body hinged to the upper part of the container main body, an insertion plate made of a desiccant-containing plastic is provided at the bottom part. An embedded container is known (see Patent Document 1).

JP-A-9-12064

  However, when a plate-like product typified by a blood glucose sensor is stored and stored in the container as described above, when removing the plate-like product, the container is shaken or the finger is inserted into the container after the lid is opened. There was a problem that it was necessary and the removal was extremely troublesome. Also, since taking out from the container is cumbersome, it takes longer time to open the lid, and as a result, the desiccant is consumed quickly, and products that dislike moisture absorption such as blood glucose level sensors should be stored for a long time. Therefore, as a container for storing a plate-like product that is not suitable for moisture absorption, improvement of its drying property is required.

  Accordingly, an object of the present invention is a container for storing a plate-like product that dislikes moisture absorption, such as a blood glucose level sensor, which can be easily taken out, and is excellent in sustainability of dryness and long. The object is to provide a container capable of effectively preventing moisture absorption of a plate-like product over a period of time.

According to the present invention, a cylindrical body having a cylindrical space having an open upper end and a lower end closed by a bottom wall, and an opening of the cylindrical space are provided to be closed. A plate-shaped product storage container in which a plurality of plate-shaped products having the same size are stored in the cylindrical space.
The surface of the bottom wall on the cylindrical space side is a hygroscopic surface formed by a hygroscopic resin in which a desiccant is dispersed in the resin, and the hygroscopic surface extends while being inclined upward from below. And
The plurality of plate products are supported and accommodated by the hygroscopic surface such that an upper portion projects from the opening and an upper end thereof forms an inclined surface parallel to the hygroscopic surface of the bottom wall. A container for receiving a plate-like product is provided.

In the container of the present invention,
(1) The bottom wall includes a bottom wall substrate extending obliquely from below to above, and a layer of the hygroscopic resin formed on the inclined surface of the bottom wall substrate on the cylindrical space side. Being formed,
(2) The hygroscopic resin layer extends to the inner surface of the cylindrical body,
(3) The lid body is hinged to the upper end of the cylindrical body, and the hinge coupling portion is located above the uppermost portion of the bottom wall;
Is preferred.

  In the container of the present invention, the surface on the cylindrical space side of the bottom wall that closes the cylindrical space in which the plate-shaped product is accommodated is an inclined surface, and a plurality of plate-shaped products ( That is, a bundle of plate products is supported and accommodated. In this way, the bundle of plate-like products accommodated in the cylindrical space has an upper surface protruding from the opening of the cylindrical space and forming an inclined surface parallel to the inclined surface of the bottom wall. Therefore, the plate-like product can be easily taken out by pulling out the plate-like products one by one from the inclined surface of the upper surface of the plate-like product.

  In the container of the present invention, the inclined surface of the bottom wall as described above is formed from a hygroscopic resin in which a desiccant is dispersed in the resin, and the inclined surface is a hygroscopic surface. That is, since the hygroscopic surface is an inclined surface, the hygroscopic surface has a larger area compared to the case where the horizontal surface is the hygroscopic surface, and as a result, the hygroscopic surface exhibits a high hygroscopic action and the drying ability is high. Moreover, since it is possible to easily open the lid and take out the plate-like product, the time for opening the lid to take out the plate-like product is shortened, so that the desiccant is consumed. It is effectively suppressed and a high drying capacity can be maintained continuously.

  Therefore, the container of the present invention can hold a plate-like product such as a blood glucose level sensor that dislikes moisture absorption in a dry state for a long period of time, and can effectively prevent performance degradation due to moisture absorption.

It is a figure which shows the side cross section of the container of this invention in the state which opened the cover body and accommodated the plate-shaped product. It is a top view in the state where the lid of the container of Drawing 1 was opened. It is a side view in the state where the lid of the container of Drawing 1 was opened. It is a side view in the state where the lid of the container of Drawing 1 was closed. It is a figure which shows the side cross section of the other example of the container of this invention in the state which opened the cover body and accommodated the plate-shaped product.

  1 to 4 showing a preferred example of the container of the present invention, this container is roughly composed of a cylindrical body 1 and a lid 3 hinged to the upper part of the cylindrical body 1. The cylindrical space A inside the cylindrical body 1 is closed by the bottom wall 5, and a plate-shaped product indicated by 50 is accommodated in the cylindrical space A. .

  A circumferential projection 7 is formed on the upper end surface of the cylindrical body 1 to lock the lid 3 in a closed state.

  The lid 3 includes a top plate portion 10 and a skirt 11 extending from the periphery of the top plate portion 10, and the skirt 11 includes a central band 13 and its periphery as shown in FIG. 2. Two auxiliary bands 15, 15 located on both sides in the direction are hinged to the upper part of the cylindrical body 1, and the cylindrical space A is closed by turning and closing the lid 3. The plate-like product 50 accommodated in A is sealed and held. The central band 13 is joined to the upper end portion of the cylindrical body 1, and the auxiliary bands 15 and 15 are connected to the outer surface of the cylindrical body 1 at a position lower than the central band 13. When the lid 3 is opened, the opened state is stably maintained by hinge connection with such a band.

  Further, a concave portion 17 is formed in a circumferential shape on the inner surface of the lower end (the upper end in FIG. 1) of the skirt 11, and when the lid 3 is closed, the concave portion 17 is formed around the cylindrical body 1. By engaging with the projection 7, the lid 3 is stably held in the closed state.

  Further, an opening ridge 19 is formed on the opposite side of the lower end of the skirt 11 from the hinge connection portion, and a flat convex portion 20 is formed on the back surface (lower end surface) of the ridge 19. Has been. As shown in FIG. 4, when the lid 3 is closed, the lid 3 can be easily lifted by hooking a finger on the convex portion 20 on the back surface of the collar 19 and pulling the lid 3 upward. Can be opened.

  In the container of the present invention having the above-described structure, as shown particularly in FIG. 1, a bottom wall substrate 21 in which the bottom wall 5 is continuous with the cylindrical body 1, and a cylinder of the bottom wall substrate 21. And a hygroscopic resin layer 23 provided on the surface on the side of the space A. That is, the bottom wall 5 is made of a thermoplastic resin forming the cylindrical body 1 or the lid 3, such as low-, medium- or high-density polyethylene, linear low-density polyethylene, polypropylene, thermoplastic polyester, polyamide, The hygroscopic resin layer 23 is formed of a hygroscopic resin in which a desiccant is dispersed in such a thermoplastic resin.

  In the hygroscopic resin as described above, as the desiccant, for example, porous inorganic powders such as activated clay, activated carbon and the like, which have been made porous by acid treatment of clay minerals such as silica gel, various zeolites, smectite and the like, and have increased specific surface area In general, such a desiccant is dispersed in an amount of about 40 to 60 parts by weight per 100 parts by weight of the resin.

  In the present invention, it is important that the bottom wall 5 as described above is inclined. Specifically, as understood from FIG. 1, the bottom wall substrate 21 is inclined upward from the lower end. The hygroscopic resin layer 23 is formed on the inclined surface on the cylindrical space A side. Therefore, the surface of the hygroscopic resin layer 23 is an inclined surface, and this inclined surface is hygroscopic. It becomes the surface 23a. That is, moisture absorption in the cylindrical space A is performed from such a moisture absorbing surface 23a, and the plate-like product 50 that is housed inside and held in a sealed state by the lid 3 is held in a dry state. Moisture absorption of the shaped product 50 is prevented.

  According to the structure as described above, the moisture absorbing surface 23a has a larger area than the case where the bottom wall 5 is held in a horizontal state and the moisture absorbing surface 23a is a horizontal surface. ) Will increase.

  In the present invention, a large number of plate-like products 50, that is, bundles of plate-like products 50 are stood and accommodated on the moisture absorbing surface 23a of the bottom wall 5 as described above. As understood from FIG. 1, the upper part of the bundle of plate-like products 50 accommodated in the cylindrical space A and held by the moisture absorption surface 23a is from the opening (indicated by 30 in FIG. 1) of the cylindrical space A. It is important that it protrudes. That is, the upper end of such a plate-like product 50 forms an inclined surface 51 that protrudes from the opening of the cylindrical space A and is parallel to the inclined moisture absorbing surface 23a. Therefore, when the lid 3 is opened, the most protruding plate-like product 50 can be easily pulled out without putting a finger into the cylindrical space A, and after one plate-like product 50 is taken out When the lid 3 is immediately closed, the remaining plate-like product 50 is again kept in a sealed state, and is kept in a dry state by moisture absorption from the moisture absorption surface 23a.

  That is, in the present invention, since the plate-like product 50 accommodated in the cylindrical space A can be easily taken out, the time during which the lid 3 is opened for taking out the plate-like product 50 is shortened. Therefore, the hygroscopic effect from the hygroscopic surface 23a can be expressed over a long period of time. That is, when the lid 3 is opened, the atmosphere containing moisture enters from the outside into the container, so that the longer the lid 3 is opened, the longer it is dispersed in the hygroscopic resin layer 23. Although the desiccant absorbs moisture and is consumed, in the present invention, since the opening time of the lid 3 is shortened, moisture absorption from the moisture absorbing surface 23a is effectively performed over a long period of time, and the plate-like product 50 is taken out. Even when the operation is repeated, it is possible to maintain the plate-like product 50 accommodated in a dry state for a long period of time.

  In the present invention, the above-described angle θ of the hygroscopic surface 23a (corresponding to the inclination angle θ of the inclined surface 51 formed by the upper end of the bundle of plate-like products 50) is the entire upper portion of the bundle of plate-like products 50 accommodated. However, the size of the plate-shaped product 50 may be such that the plate-shaped product 50 can be easily pulled out one by one. The specific value differs depending on the thickness of the plate-like product 50 and the maximum number of the plate-like products 50 accommodated in the container, and cannot be generally defined. For example, a commonly used blood sugar level sensor or the like Is usually about 15 to 45 degrees.

  Further, as understood from FIGS. 1 and 3, the hinge connecting portion (in particular, the central band 13) of the lid 3 is configured to be positioned above the uppermost portion 5 a of the inclined bottom wall 5. It is good to be. That is, when the hinge connecting portion is located on the opposite side, when the lid 3 is closed, the upper part of the plate-like product 50 protruding from the cylindrical space A becomes an obstacle, and the lid 3 is completely closed. It is because there exists a possibility that it may become difficult.

  In the container having the above-described structure, the hygroscopic resin layer 23 is formed by injection molding using a hygroscopic resin, and then the cylinder having the bottom wall substrate 21 is formed using the hygroscopic resin layer 23. The body 1 and the lid 3 can be manufactured by two-color molding in which molding is integrally performed by injection molding.

  Further, a hygroscopic resin plate having a shape corresponding to the hygroscopic resin layer 23 is formed by extrusion molding or the like, and further, the cylindrical body 1 and the lid body 3 provided with the bottom wall substrate 21 are separately molded, It is also possible to manufacture a container having the hygroscopic resin layer 23 by fitting a hygroscopic resin plate so as to be in close contact with the bottom wall substrate 21.

  In addition, the bottom wall 5 can be formed of only a hygroscopic resin. In this case, the back surface of the bottom wall 5 (surface opposite to the cylindrical space A) is always in contact with the atmosphere. For this reason, the desiccant in the hygroscopic resin is consumed quickly. Therefore, it is preferable to form the hygroscopic resin layer 23 only on the surface of the bottom wall substrate 21 on the cylindrical space A side.

  Further, the foot 1a protruding downward from the bottom wall 5 of the cylindrical body 1 is essentially an unnecessary part. However, such a foot 1a is formed, and the lower end of the cylindrical body 1 is A structure that forms a horizontal plane is preferable from the viewpoint of stabilizing the container.

  Furthermore, in the present invention, the hygroscopic resin layer 23 as described above may extend to the inner surface of the cylindrical body 1. The structure of such a container is shown in FIG.

That is, in the container of FIG. 5, the hygroscopic resin layer 23 extends from the surface of the bottom wall substrate 21 to the inner surface of the cylindrical body 1, and the bottom wall 5 and the cylindrical body 1 that form the cylindrical space A are formed. The entire inner surface is formed by the hygroscopic resin layer 23, and the entire cylindrical space A faces the hygroscopic surface 23a. By adopting such a structure, the hygroscopic effect can be maximized.
The container shown in FIG. 5 has the same structure as the container shown in FIGS. 1 to 4 except that the hygroscopic resin layer 23 is formed as described above.

  Furthermore, although not illustrated, in the container of FIGS. 1 to 5, the inclined surface 51 formed by the upper end of the bundle of plate-like products 50 when the lid 3 is closed on the inner surface of the top plate portion of the lid 3. The head space when the lid 3 is closed can be minimized, and the moisture absorption capacity of the container can be maximized. Further, in this case, the outer surface shape of the lid body 3 is preferably an inclined shape corresponding to the inner surface shape of the lid body 3, thereby reducing the amount of resin without making the lid body 3 thick, Cost can be reduced.

  The above-described container of the present invention can not only easily take out the plate-like product, but also has a very high hygroscopic capacity and effectively prevents the desiccant from being consumed, and the high hygroscopic capacity is stable over a long period of time. Therefore, it is effectively applied to the storage of plate-like products that hate moisture such as blood glucose level sensors and urine test paper.
