Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for moisture-proof storage of test pieces used for body fluid tests such as urine tests.

[0002]

2. Description of the Related Art Test pieces used for urine tests and the like are roughly classified into a type in which a reaction indicator is carried on a filter paper, which is a water-absorbent material, and a type in which a water-absorbent coating liquid is applied (printed, etc.). It
Currently, a test piece having a test section and a judgment section on a support, or a test piece having a judgment section separately attached to the storage container is used. Since the test method using these test pieces can be performed easily, it is suitable for mass examinations and daily health checks.

The test pieces are manufactured by filtering paper impregnated with a test agent or coating the test agent by screen printing. Both are stick type, as shown in FIG. 6, a method of integrated packaging with a desiccant in a container with a lid of a glass or plastic bottle, and a method of individually packaging with an desiccant with an Al foil packaging material as shown in FIG. There is. However, since the glass or plastic bottle is repeatedly opened, the performance of the final inspection stick due to repeated use is remarkably impaired in the case of a large accumulation unit. Further, although it is certain that the aluminum foil packaging material is individually packaged, there is a problem that it takes time and cost.

[0004]

Therefore, the problem to be solved by the present invention is to take out only the amount used at the time of opening in order to maintain the performance of the test piece, and to prevent the performance deterioration of the unused test piece. It is to provide a moisture-proof storage container for a test piece.

DISCLOSURE OF THE INVENTION The present invention is a container for use while moisture-proofing a test piece, wherein a circular tube having a double structure is in contact with one surface of the container up to the opposite surface. The tube and the outer tube are provided with a slit having a width longer than the length of the test piece in the longitudinal direction, the outer tube has a container and a test piece receiver at the edge of the slit while keeping airtightness other than the slit, and the inner tube is A storage container for test pieces, which is rotatable while maintaining airtightness with an outer tube and has a hermetically-sealing lid at one end protruding from the container. Further, as an embodiment, the lid is transparent, the container, the outer tube, and the wall of the inner tube are shielded from light, and the moisture-proof storage container for the above-described test piece is made of a material for preventing water vapor permeation. An example of the moisture-proof storage container for the above-mentioned test piece is one in which the outer space of the double-tube structure is filled with a desiccant or the wall surface around the space is coated with a desiccant.

A detailed description will be given below with reference to the drawings. FIG. 1 is a schematic explanatory view showing an embodiment of the present invention. Container 1
A circular tube 3 having a double structure consisting of an inner tube 4 and an outer tube 5 is passed from the upper surface 2 to a bottom surface 10, and the outer tube 5 is airtight at a portion which is also in contact with the bottom portion 10 and the upper surface 2 of the container 1. It is glued or welded to keep it. The inner tube 4 and the outer tube 5 have a slit 6 having a width longer than the length of the test piece in the longitudinal direction, and the outer tube 5 has a test piece receiver 7 at the edge of the slit 6. Further, packing 9 is provided so that air does not enter between the inner pipe 4 and the outer pipe 5. The inner tube 4 has an airtight lid 8
Is provided so that the inner tube 4 can be rotated with the lid 8 still attached. After the test piece is placed on the test piece receiver 7, the inner tube 4 is rotated and the slits 6 are aligned with each other to fix the test piece to the inner tube 4. Then, the inner tube 4 is rotated, and with the slits 6 not aligned with each other, the lid 8 is opened and the test piece is taken out.

FIG. 2 is an exploded view of the components of the container shown in FIG. FIG. 3 is a schematic explanatory view showing another embodiment of the present invention. The difference from FIG. 1 is that the double tube portion is below the upper surface 2 of the container 1, and the shape of the packing 9 between the inner tube 4 and the outer tube 5 is devised. FIG. 4 is an exploded view of the components of the container of FIG.

FIG. 5 is an explanatory view of a cross section of the central portion of the container 1 of FIG. There is a state (b) in which the inner tube 4 is rotated and the slits 6 are aligned with each other, and (a) shows a normal storage state.
Is.

As the material of the container, a plastic such as polyethylene, polypropylene, vinyl chloride, polyacrylonitrile, polyester, or an aluminum can, or a glass bottle is used. Here, it is devised so that the inner tube and the outer tube fit together, and by providing a test piece receiver 7 on the outer side of the inner tube that accommodates several test pieces to be used, and adjusting the slit width, only the required number Can be taken out. At this time, the smaller the connecting area between the inner pipe and the outer pipe, the more the moisture-proof property of the atmosphere in the storage space of the outer pipe is maintained.

The connecting portion between the inner tube and the outer tube is a strip-shaped test piece, and a slit width of about 0.4 mm allows passage of one sheet, and the slit width can be changed according to the required number. A small space is enough for the inner tube, and it is set according to the maximum number of sheets to be taken out. Usually, it is about 1/10 of the outer tube volume.

The thickness of the container is set by various barrier properties of the material. In the case where importance is attached to moisture resistance, it is preferable to use polyethylene or polypropylene and mold with a wall thickness of 1 mm or more. The plastic material can be multi-layered if necessary, and can be multi-layered with vinylidene chloride as an intermediate layer or can be thinned by glass vapor deposition. Further, since glass bottles and aluminum cans have higher barrier properties than plastics, they can be used for those requiring high moisture resistance. It is preferable to use a transparent material capable of blocking light rays of 350 nm or less in order to provide a light-shielding property and confirm the remaining amount of the content.

[0012]

In the test strip storage container of the present invention, even if a large amount of test strips are collectively packaged in the same container and repeatedly used and opened, it is possible to prevent the deterioration of quality as much as individual packaging. In addition, the storage space can be minimized because they can be stored collectively.
