The configuration of disposal container 10 for a test apparatus of an embodiment is described with reference to FIG. 1 to FIG. 8.

(Overview of Disposal Container for Testing Apparatus)

FIG. 1 illustrates disposal container 10. Disposal container 10 is used by being installed to installation part 910 of testing apparatus 900. Testing apparatus 900 includes test piece transfer part 940 to transfer test pieces 510 used in the testing apparatus and to drop the test pieces into disposal container 10. Testing apparatus 900 includes discharge pipe 996a to transfer liquid waste 520 produced due to the operation of the testing apparatus and to discharge the liquid waste into disposal container 10.

Disposal container 10 includes disposal container body 10a having lateral wall 11 and bottom wall 12 continuously provided at a lower end of lateral wall 11. Disposal container 10 is formed in the shape of a box and is disposable. Lateral wall 11 includes two or more lateral walls. The two or more lateral walls include lateral wall 11a and lateral wall 11b. Disposal container 10 is formed of paper with liquid absorbency and flexibility. To be more specific, disposal container 10 is formed of coated board with white front surface and white back surface. The coated board is made from wood pulp, recycled fiber, or the like. Disposal container 10 may be made of synthetic paper which is made mainly from synthetic fiber.

Opening portion 14 opened upward is provided in an upper end portion 13 of disposal container 10. Opening portion 14 is provided in order to receive, from above to the inside, test pieces 510 which is transferred and dropped by test piece transfer part 940 of testing apparatus 900 after being used in testing apparatus 900. Test piece 510 is an object onto which a living body specimen is dripped for a test. Test piece 510 is a test strip. Test piece 510 includes reaction part 510a to react with the dripped living body specimen. In order to be applied to a test with two or more test items, test piece 510 may include two or more reaction parts 510a corresponding to the respective test items. After being used for a test, test pieces 510 are dropped, through opening portion 14, from above disposal container 10, and then are stored inside disposal container 10.

Opening portion 15 is provided on lateral wall 11a of disposal container 10. Opening portion 15 is opened laterally. Disposal container 10 is arranged such that opening portion 15 faces toward the center side of testing apparatus 900. Opening portion 15 is formed at a height position lower than opening portion 14. Opening portion 15 is provided in order to receive liquid waste 520 laterally to the inside of disposal container 10. Liquid waste 520 is produced due to the operation of testing apparatus 900 and is transferred by discharge pipe 996a. End 996b of discharge pipe 996a of testing apparatus 900 is configured to be inserted into opening portion 15. Liquid waste 520 is transferred through opening portion 15 laterally into disposal container 10, and then is stored inside disposal container 10.

The above configuration makes it possible to collect test pieces 510 and liquid waste 520 together in one place and then to easily dispose of the collected test pieces and liquid waste, even if test pieces 510 are used and liquid waste 520 is produced due to the operation of testing apparatus 900. In other words, it is possible to collect used test pieces 510 and liquid waste 520 together in one place and then to easily dispose of the collected test pieces and liquid waste.

Moreover, the above configuration makes it possible to separately collect test pieces 510 and liquid waste 520 through opening portion 14 and opening portion 15, respectively. Thus, test pieces 510 and liquid waste 520 are smoothly collected without obstructing each other when being stored into the inside of disposal container 10. In addition, disposal container 10 is disposable. Hence, biohazards can be suppressed with ease.

(Detailed Configuration of Disposal Container for Testing Apparatus)

Hereinbelow, a configuration of a preferred embodiment of disposal container 10 illustrated in FIG. 1 is described in detail with reference to FIG. 2 and the following drawings.

As illustrated in FIG. 2, disposal container body 10a of disposal container 10 is formed substantially in the shape of a rectangular parallelepiped opened upward. In a plan view, disposal container body 10a has the shape of a rectangle formed from opposed longer sides and opposed shorter sides. Disposal container body 10a includes four lateral walls. The four lateral walls are lateral wall 11a to lateral wall 11d. Lateral wall 11a and lateral wall 11b are the longer-side lateral walls, have the same outline shape, and are opposed to each other. Lateral wall 11c and lateral wall 11d are the shorter-side lateral walls, have the same outline shape and area, and are opposed to each other. Lateral wall 11a is orthogonal to lateral wall 11c and lateral wall 11d. Lateral wall 11b is orthogonal to lateral wall 11c and lateral wall 11d. Disposal container 10 includes disposal container body 10a, resin sheet 101b which covers outer surface 10b of disposal container body 10a, and resin sheet 101c which covers inner surface 10c of disposal container body 10a. Note that outer surface 10b of disposal container body 10a may not be covered with resin sheet 101b. Inner surface 10c of disposal container body 10a may not be covered with resin sheet 101c.

Opening portion 14 is formed in such a shape that entire upper end portion 13 of disposal container body 10a is opened. Opening portion 14 has the shape of a rectangle in a plan view. There is provided one opening portion 14. Note that disposal container body 10a may be provided with a top wall, and opening portion 14 may be provided in a way to penetrate portion of the top wall. Opening portion 14 may have a shape other than that of a rectangle in a plan view. There may be provided two or more opening portions 14.

Opening portion 15 is formed at a position higher than the height position of the center of disposal container body 10a. To be more specific, opening portion 15 is formed in a region in the vicinity of an upper end of lateral wall 11a and the vicinity of either one of the lateral ends thereof. In more detail, opening portion 15 is formed in a region in the upper right of lateral wall 11a when lateral wall 11a is viewed from the front. Height H2 of a lower end portion of opening portion 15 is higher than height H1 of the center of disposal container body 10a. Opening portion 15 is formed within a region higher than the height position of the center of disposal container body 10a. Opening portion 15 is formed at a position of upper portion 10u higher than the height position of the center of disposal container body 10a, and at center position 101u or in the vicinity of center position 101u of upper portion 10u in a height direction of disposal container body 10a. This makes it possible to store liquid waste 520 to a level higher than the height position of the center of disposal container body 10a when liquid waste 520 is to be stored into the disposal container body 10a. As a result, the amount of liquid waste 520 stored can be made large. In addition, liquid waste 520 is allowed to be stored into the inside of disposal container body 10a through opening portion 15 formed at lateral wall 11a. Thereby, the height of entire disposal container body 10a can be made large, compared to the case where the height of disposal container body 10a is made small such that end 996b of discharge pipe 996a is positioned in an upper part of opening portion 14 of disposal container body 10a, and liquid waste 520 from discharge pipe 996a is stored into the inside of disposal container body 10a through opening portion 14. Thus, it is possible to store more test pieces 510 inside disposal container body 10a. Incidentally, opening portion 15 may be formed at a height position equal to or lower than the height position of the center of disposal container body 10a.

Opening portion 15 is provided on the lateral wall 11d side of lateral wall 11a. Opening portion 15 is formed in the shape of a circle. There is provided one opening portion 15. Opening portion 15 may have a shape other than that of a circle. Although opening portion 15 is an independent opening portion which is not connected to opening portion 14 located above, opening portion 15 may be formed of a notch connected from opening portion 14. There may be provided two or more opening portions 15. An edge portion of opening portion 15 is formed by lateral wall 11a. A periphery of opening portion 15 is surrounded by lateral wall 11a. This makes it possible to increase the strength of lateral wall 11a and to suppress deformation of the shape of disposal container body 10a even in the case where liquid waste 520 is stored into disposal container body 10a.

Lateral wall 11a is provided with engagement portion 16. Engagement portion 16 is formed at a position higher than the height position of the center of disposal container body 10a. To be more specific, height H3 of a lower end portion of engagement portion 16 is higher than height H1 of the center of disposal container body 10a. Height H3 of the lower end portion of engagement portion 16 is lower than height H2 of the lower end portion of opening portion 15. Engagement portion 16 is provided substantially at the center of lateral wall 11a in a horizontal width direction when viewed from a direction orthogonal to lateral wall 11a. Engagement portion 16 is formed as a hole. Engagement portion 16 is formed in an oblong shape which extends in a direction parallel to bottom edge 12a on lateral wall 11a when viewed from the direction orthogonal to lateral wall 11a. Incidentally, the height of the lower end portion of engagement portion 16 may be substantially equal to that of the lower end portion of opening portion 15.

As illustrated in FIG. 3, transparent window portion 17 is provided in disposal container 10. Window portion 17 is formed by covering opening 17a provided on lateral wall 11b with transparent resin sheet 101b. This makes it possible to check the stored matter inside disposal container body 10a through window portion 17 even in the case where disposal container body 10a is visually checked from the outside. Incidentally, window portion 17 may be formed of a material other than resin. Window portion 17 may be semi-transparent.

Window portion 17 is provided in lateral wall 11b opposed to lateral wall 11a. This makes it possible to arrange disposal container 10 in testing apparatus 900 such that opening portion 15 to receive liquid waste 520 into the inside of disposal container 10 faces toward the center side of testing apparatus 900, and window portion 17 faces toward the outside of testing apparatus 900. As a result, it is possible to visually check the inside of disposal container 10 through window portion 17 while storing with ease liquid waste 520 produced due to the operation of the apparatus into the inside of disposal container 10.

Window portion 17 has the shape of a rectangle extending in an up-and-down direction. Window portion 17 is formed in a way to extend in the up-and-down direction from a lower portion toward an upper portion of disposal container body 10a. Window portion 17 is formed in a way to extend toward an up-direction from the vicinity of lower end portion 20 of disposal container body 10a to the position of upper portion 10u higher than the height position of the center of disposal container body 10a. Window portion 17 extends from a region lower than the height position of the center of disposal container body 10a to a region higher than the height position of the center of disposal container body 10a. In more detail, window portion 17 is configured in a way to extend to a position higher than a lower end position of opening portion 15. This makes it possible to recognize with ease the change in stored amount even in the case where the stored matter inside disposal container body 10a increases. Incidentally, window portion 17 may be located in a region lower than the height position of the center of disposal container body 10a. Window portion 17 may be located in a region higher than the height position of the center of disposal container body 10a.

Window portion 17 is formed such that its width W2 is smaller than half width W1 of lateral wall 11b in a width direction of lateral wall 11b. Window portion 17 is formed such that its width W2 is smaller than half width W1 of lateral wall 11b in a direction parallel to bottom edge 12b on lateral wall 11b. Window portion 17 is formed such that its width W2 is smaller than width W3 of lateral wall 11c in a direction parallel to bottom edge 12c on lateral wall 11c.

Various configurations can be employed for window portion 17. As illustrated in FIG. 4, window portion 17 may be formed in a shape other than that of a rectangle, for example, an ellipse. As another configuration, window portion 17 may have a width larger than half width W1 of lateral wall 11b in the direction parallel to bottom edge 12b on lateral wall 11b when viewed from a direction orthogonal to lateral wall 11b. In addition, as illustrated in FIG. 5, window portion 17 may be provided except in lateral wall 11b, for example, in lateral wall 11d orthogonal to lateral wall 11a. Window portion 17 may be provided in lateral wall 11c orthogonal to lateral wall 11a.

Outer surface 10b of disposal container body 10a is covered with waterproof resin sheet 101b. This makes it possible to suppress leakage of liquid to the outside of disposal container 10 even in the case where the liquid is stored into the inside of disposal container 10.

As illustrated in FIG. 3, resin sheet 101b covers entire outer surface 10b. The material for resin sheet 101b is polypropylene (PP). Resin sheet 101b may cover part of outer surface 10b. The material for resin sheet 101b may be that other than polypropylene.

Opening 17a is provided in lateral wall 11b opposed to lateral wall 11a. Outer surface 10b of disposal container body 10a and opening 17a together are covered with resin sheet 101b. Thereby, window portion 17 is formed. Resin sheet 101b is transparent. This makes it possible to form window portion 17 with ease compared to the case where window portion 17 is formed by covering opening 17a with resin sheet 101b separately from outer surface 10b of disposal container body 10a. Incidentally, resin sheet 101b may be semi-transparent.

Inner surface 10c of disposal container body 10a is covered with waterproof resin sheet 101c. Resin sheet 101c covers entire inner surface 10c. The material for resin sheet 101c is polypropylene, as with the material for resin sheet 101b. Resin sheet 101c may cover part of inner surface 10c. The material for resin sheet 101c may be that other than polypropylene. Resin sheet 101c and resin sheet 101b may be made of materials different from each other.

Disposal container body 10a is formed of paper with liquid absorbency. As illustrated in FIG. 6, holes 101d to expose an upper surface (inner bottom surface) of bottom wall 12 of disposal container body 10a are formed with resin sheet 101c covering inner surface 10c. In a plan view, multiple holes 101d are provided to be arranged in a line. Thus, the liquid stored into the inside of disposal container 10 is absorbed into disposal container body 10a formed of paper through holes 101d. As a result, stains of the liquid absorbed into disposal container body 10a make it possible to recognize that disposal container 10 is already used. Thus, it is possible to suppress repeated use of disposal container 10 already used, and to suppress biohazards.

In addition, there may be provided one hole 101d. Holes 101d may be formed substantially in the shape of a curve. Holes 101d may be formed with resin sheet 101c at a position corresponding to lateral wall 11.

As illustrated in FIG. 3, disposal container body 10a is provided with cover portion 18. Cover portion 18 is provided in order to cover opening portion 14 and opening portion 15 when disposal container 10 is to be disposed of. Cover portion 18 includes a portion that is configured to cover opening portion 14 and a portion that is configured to cover opening portion 15. This makes it possible to suppress spillage of the stored matter from the inside to the outside of disposal container 10 when disposal container 10 is to be disposed of. Incidentally, disposal container body 10a may not be provided with cover portion 18.

Window portion 17 and opening portion 15 are formed in positions not overlapping each other when viewed from the direction orthogonal to lateral wall 11a. To be more specific, window portion 17 and opening portion 15 are arranged to be lined in a right-left direction when viewed from the direction orthogonal to lateral wall 11a. Window portion 17 and opening portion 15 are arranged on opposite sides from each other with respect to a straight line orthogonal to lateral wall 11a at the center position of lateral wall 11a. Also, in a plan view, window portion 17 and opening portion 15 are arranged at positions diagonal to each other. This makes it possible to prevent window portion 17 to be covered with cover portion 18 even in the case where cover portion 18 is provided, which is capable of closing opening portion 15 by being folded back from the lateral wall 11b side to the lateral wall 11a side, and in the state where cover portion 18 is arranged on the lateral wall 11b side and opening portion 15 is not closed.

Cover portion 18 is formed integrally with disposal container body 10a. This makes it possible to close opening portion 14 and opening portion 15 with ease when disposal container 10 is to be disposed of, unlike the case where cover portion 18 is provided separately from disposal container body 10a. As a result, disposal container 10 can be handled with ease at the time of disposal. Incidentally, cover portion 18 may be provided separately from disposal container body 10a.

Cover portion 18 is provided with a joint portion 18a. Cover portion 18 is joined to upper end 111b of lateral wall 11b opposed to lateral wall 11a via joint portion 18a. This makes it possible to join cover portion 18 to disposal container body 10a with ease via joint portion 18a.

Cover portion 18 is provided with adhesion portion 18b. Cover portion 18 is bonded to lateral wall 11b using adhesion portion 18b in a detachable state. Adhesion portion 18b is an adhesive. This makes it possible to arrange with ease disposal container 10 in testing apparatus 900, with cover portion 18 fixed to lateral wall 11b in the state before disposal where opening portion 14 and opening portion 15 do not have to be closed. Cover portion 18 may be attached using an adhesive tape, for example. Cover portion 18 may not be bonded to lateral wall 11b in a detachable state.

Note that when opening portion 14 and opening portion 15 are to be closed, joint portion 18a and bendable portion 18d are bent. Thereby, cover portion 18 covers opening portion 14 and opening portion 15.

Cover portion 18 includes cutout portion 18e. A part of cover portion 18 is cut out by cutout portion 18e along window portion 17 in the shape of a rectangle. Cover portion 18 is arranged on lateral wall 11b in the state where window portion 17 is exposed by cutout portion 18e. Cover portion 18 exposes window portion 17 through cutout portion 18e in the state where opening portion 14 and opening portion 15 are not closed. Cover portion 18 is bonded to lateral wall 11b by adhesion portion 18b in the state where window portion 17 is not covered. Thus, in the state before disposal where opening portion 14 and opening portion 15 are not closed, it is possible to arrange with ease disposal container 10 in testing apparatus 900, and to check the stored matter inside disposal container 10 even in the case where disposal container 10 is visually checked from the outside. In the configuration example of FIG. 3, window portion 17 is exposed even in a closed state. Window portion 17 may be covered in the closed state.

Cover portion 18 is provided with engagement portion 18c. Engagement portion 18c is provided in order to engage with engagement portion 16 of lateral wall 11a at the time of disposal. Engagement portion 18c is formed in a shape which allows engagement with slit-shaped engagement portion 16. As illustrated in FIG. 7, cover portion 18 is bent from the lateral wall 11b side to the lateral wall 11a side. Thereby, opening portion 14 and opening portion 15 are closed. At this moment, engagement portion 18c is inserted into engagement portion 16. Engagement of engagement portion 16 with engagement portion 18c maintains a state where opening portion 14 and opening portion 15 are closed by cover portion 18. Note that in FIG. 7, opening portion 15 is illustrated using a dashed line for the sake of the convenience of explanation. Incidentally, cover portion 18 may not be provided with engagement portion 18c.

Meanwhile, another configuration may be employed as the configuration of disposal container 10. As illustrated in FIG. 8, for example, flake-shaped flaps 19 may be provided on upper end portion 13 of disposal container body 10a. One pair of flaps 19 can be provided, for example. Flaps 19 are formed within the outline of disposal container 10 in a plan view. Flaps 19 are bent to the inner side of disposal container 10. Flaps 19 can suppress spillage of the stored matter from the gaps between upper end portion 13 and cover portion 18 to the outside when disposal container 10 is to be disposed of.

Note that living body specimen 700 may be other than urine 700a, and testing apparatus 900 may be an apparatus which tests living body specimen 700 other than urine 700a.

(Detailed Description of Installation part)

As illustrated in FIG. 10, installation part 910 installs disposal container 10 in a detachable manner. Installation part 910 includes holder portion 911, on the inner surface side, which is capable of retaining disposal container 10. Holder portion 911 is a container with an opening opened in its upper side. Installation part 910 is installed to testing apparatus body 900b on pivot shaft 910a. Installation part 910 can be opened and closed to testing apparatus body 900b with pivot shaft 910a as the pivot center.

Installation part 910 in an open state can install disposal container 10 to holder portion 911. An outer frame portion of bottom portion of holder portion 911 is connected to one end of open state retention member 911a. Another end of open state retention member 911a is connected to the body of testing apparatus 900. Open state retention member 911a is formed from a spring. Open state retention member 911a applies a biasing force toward the outside of testing apparatus 900 to installation part 910 by acting a biasing force pulling bottom portion of holder portion 911 upward on holder portion 911. This ensures that the open state of installation part 910 is maintained. Open state retention member 911a may be other than a spring as long as it can apply a biasing force.

Installation part 910 is provided with engagement portion 912a on the inner surface side. Engagement portion 912b is provided at a position of testing apparatus 900 corresponding to engagement portion 912a of installation part 910 in the close state. Installation part 910 is pushed to the inner side of testing apparatus 900, and engagement portions 912a and 912b are engaged. Thereby, the close state of installation part 910 is maintained. Installation part 910 with disposal container 10 installed to holder portion 911 is brought to the close state. In the state, it is possible to collect test pieces 510 and liquid waste 520 produced due to the operation of testing apparatus 900 using disposal container 10. Incidentally, installation part 910 may not be provided with engagement portion 912a. Testing apparatus 900 may not be provided with engagement portion 912b.

Opening portion 914 is formed in outer surface 913 of installation part 910. Opening portion 914 is formed at a position corresponding to window portion 17 provided in disposal container 10, in the state where disposal container 10 is installed to installation part 910. This makes it possible to check the stored matter inside disposal container body 10a even in the case where testing apparatus 900 is visually checked from the outside.

Opening portion 914 exposes window portion 17 provided in disposal container 10, in the state where disposal container 10 is installed to installation part 910. Opening portion 914 may have a shape different form that of window portion 17 illustrated in FIG. 10, as long as it has a shape which exposes at least part of window portion 17 in disposal container 10.

In the case where the cleaning liquid is to be discharged from liquid receiving section 983 of cleaning part 980, valve 992 is switched such that pipe 991c is connected to pipe 991d.

Valve 993 is a switching valve to connect either one of pipes 991d and 991b to pipe 991e. In the case where the liquid sent from pipe 991d is to be discharged to pipe 991e, valve 993 is switched such that pipe 991d is connected to pipe 991e. In the case where the cleaning liquid sent from pipe 991b is to be discharged to pipe 991e, valve 993 is switched such that pipe 991b is connected to pipe 991e.

Pump 994 can apply a negative pressure to a portion, except transfer unit 996, located upstream of the pumps in fluid circuit section 990. The liquid transferred due to the negative pressure of pump 994 is transferred to liquid waste storing unit 995 through pipe 991e.

Transfer unit 996 is provided in order to transfer liquid waste 520, which is the used cleaning liquid produced due to the operation of testing apparatus 900, through opening portion 15 of disposal container 10 installed to installation part 910. Transfer unit 996 makes it possible to store with ease liquid waste 520 in disposal container 10.

Transfer unit 996 is provided with discharge pipe 996a to discharge liquid waste 520. Discharge pipe 996a is formed from a pipe-shaped member such as an elastically deformable tube. Discharge pipe 996a is provided below a lower end portion of overflow liquid collection section 984 of cleaning part 980. Discharge pipe 996a is arranged at a position of the same height as that of opening portion 15, in the state where disposal container 10 installed to installation part 910 is stored in testing apparatus 900. Liquid waste 520 flows through the inside of discharge pipe 996a due to its own weight. Thus, it is possible to transfer with ease the cleaning liquid transferred from discharge pipe 996a to the inside of disposal container 10 through opening portion 15. Incidentally, discharge pipe 996a may be, for example, a pipe-shaped metal member, which does not experience elastic deformation.

End 996b of discharge pipe 996a is arranged while being fixed to testing apparatus body 900b. End 996b of discharge pipe 996a is inserted into opening portion 15 when installation part 910 is brought to the closed state of being closed to testing apparatus body 900b from the open state of being opened to testing apparatus body 900b. This makes it possible to insert with ease end 996b of discharge pipe 996a into opening portion 15 only by closing installation part 910 installed with disposal container 10. As described above, end 996b of discharge pipe 996a which transfers liquid waste 520 is inserted into opening portion 15. Thereby, it is possible to store liquid waste 520 inside disposal container 10.

End 996b of discharge pipe 996a is arranged at a position of the same height as that of opening portion 15. End 996b of discharge pipe 996a is arranged inside disposal container 10 through opening portion 15 in the state where disposal container 10 installed to installation part 910 is installed to testing apparatus 900. End 996b of discharge pipe 996a is not in contact with inner surface 10c of disposal container 10 in the state where installation part 910 installed with disposal container 10 is closed to testing apparatus body 900b. This makes it possible to reliably transfer the cleaning liquid transferred from discharge pipe 996a to the inside of disposal container 10.

As a rule, no overflow occurs in cleaning part 980 while testing apparatus 900 is in normal operation because liquid waste 520 is appropriately discharged through pipes 991b and 991c. However, when dispensing part 950 is being cleaned, there may be a case where liquid waste 520 overflows from liquid receiving section 983 of cleaning part 980. Even in the case, for example, where valve 992 in fluid circuit section 990 does not function properly and the cleaning liquid as liquid waste 520 received in liquid receiving section 983, out of the cleaning liquid supplied from the inside of nozzle 951 inserted into nozzle insertion section 982, cannot be transferred to liquid waste storing unit 995, it is possible to transfer liquid waste 520 to the inside of disposal container 10 through overflow liquid collection section 984 and transfer unit 996. Likewise, even in the case where at least one of pipes 991b to 991e, valve 993, and pump 994 in fluid circuit section 990 does not function properly, it is possible to transfer liquid waste 520 flowed to overflow liquid collection section 984 to the inside of disposal container 10 through transfer unit 996.
