In detail, the cup is used to test the presence and content of pathological components such as sugar and protein in urine, and in particular, the reagent for the above tests is attached inside the cup body, and it has a urine collection function and urine test. By improving the structure of the cup body, it is possible to make the interior of the cup body almost completely water-impermeable or moisture-impermeable before use, making it ready for use. It can be stored for a long period of time, and it is possible to reliably prevent residual urine in the cup from affecting the test reagent during the test, and by devising the attachment position of the test reagent, it can be used even if a small amount of urine is collected. The present invention aims to provide a new urinalysis cup that enables reliable testing.

(B. Summary of the Invention) The urinalysis cup of the present invention is a urinalysis cup in which a reagent for testing pathological components in urine is attached inside the cup body which is folded before use. When opened into a cup shape, the bottom of the cup is shaped to collect urine remaining in the cup body at the end of the bottom, and the test reagent is placed at a position away from the position where the urine collects. This makes it possible to reliably prevent residual urine in the cup from affecting the reaction of the test reagent during the test, and to perform accurate tests regardless of the differences in how the person conducting the test handles urine. In addition, the test can be performed reliably even with a small amount of urine collected, and the opening of the cup body is sealed along the opening surface and a desiccant material is sealed inside the cup body, thereby preventing the inside of the cup body from being exposed. It has almost perfect water permeability, allowing it to remain usable for a long period of time.

(C, Prior Art) (a, -Intrashell Background) Urinalysis, that is, measurement of the presence or content of pathological components such as glucose, protein, occult blood, ketones, urobilinogen, bilirubin, etc. in urine, or measurement of pH. This is one of the extremely important pathological tests for determining the presence and severity of a disease, and is performed during various regular checkups or at any time.

In such a urine test, a predetermined reagent is poured into the collected urine, or a test piece coated with a predetermined reagent is immersed, or urine is poured onto a stick-shaped test rod coated with a reagent. This is done by observing the color reaction of urine or the above-mentioned reagents, and a test piece or test rod is often used inside the shell. In addition, conventionally, urine tests using test pieces were often performed by collecting urine in a urine collection cup or the like and then immersing the test piece in the urine. Urinalysis cups with integrated test reagents have come to be used, in which a test piece is inevitably immersed in the urine when urine is collected in the cup. This type of urine sample cup has the advantage that it is not necessary to separately prepare a urine collection container and a test reagent.

(b. Example of conventional urinalysis cup) As such a urinalysis cup integrated with a test reagent, for example, the "Urine Test Container" described in Japanese Patent Application Laid-open No. 60-91262, or There is a "urine collection cup for urine test" described in Japanese Patent No. 185260.

Among these, the former disclosed in JP-A No. 60-91262 has a container made of a gas barrier sheet, approximately shaped like a packaging bag, and with a sealed opening, and has a predetermined shape on the inner surface of the container. A test reagent is attached by printing or other means, and when the opening is cut open and urine is collected into the container, the test reagent is immersed in the urine.

The latter, disclosed in Japanese Utility Model Application No. 60-185260, has a cup that is foldable and whose interior is sealed with a base material laminated with metal foil and synthetic resin film, and also has a cup with a sealed interior. is fixed to the wide surface of the cup by adhesive or the like, and when the opening of the cup is cut open and urine is collected into the opening, the test reagent is immersed in the urine.

(D. Problems to be Solved by the Invention) However, these conventional urinalysis cups have the following problems.

That is, in the method described in JP-A-60-91262, the test reagent is provided at a position close to the opening on the inner surface of the container, so in order to ensure that the test reagent is immersed in the collected urine, It is necessary to collect almost the entire amount of urine into the container, or to tilt the container so that the collected urine comes into contact with the test reagent. There are problems such as soiling hands and clothes, or not being able to perform an accurate test because the test reagent is not sufficiently immersed in urine.

In addition, since the urine collection cup described in Japanese Utility Model Application No. 60-185260 is provided at the bottom of the cup of the test piece to which a test reagent has been applied, even if the collected urine is small, the test reagent can be easily absorbed into the urine. It can be immersed reliably.

By the way, the reagents used in this type of test usually have a fixed urine immersion time, which is the appropriate time to cause an accurate reaction to the pathological component being tested. It is often limited. However, even if the urine collected in the cup is immediately discarded, it does not mean that no urine will remain in the cup; some amount of urine will inevitably remain, and this remaining urine will accumulate at the bottom of the cup. In this case, if the test reagent is placed at the bottom of the cup, the test reagent will be immersed in the remaining urine forever, so the reaction will be
For example, the color reaction may progress too much, or the original reaction characteristics may change due to combination with dissimilar reagent components eluted in the remaining urine. There is a problem in that a thorough inspection will not be carried out.

(E. Means for Solving the Problems) Therefore, in order to solve the above-mentioned problems, the urine sample cup of the present invention is designed so that when the cup body is opened into a cup shape, the bottom part forms a substantially mountain shape. Fold it in advance, seal the opening with a seal extending along the opening surface, fix the test piece to which the test reagent has been applied at or near the top of the bottom, and seal the desiccant material in the cup body. It was designed to do so.

Therefore, according to the urinalysis cup of the present invention, the seal at the opening of the cup body is formed by a seal strip extending along the opening surface, that is, along a direction perpendicular to the direction in which external moisture permeates into the opening surface. Since the opening is almost completely sealed and water impermeability to the inside of the cup body is sufficiently maintained, there is no possibility that water that has already existed inside the cup body or invaded the cup body due to some reason after the opening has been sealed. The water that passes through is absorbed by the desiccant material enclosed in the cup body, which almost completely prevents the test reagent from absorbing moisture and causing denaturation or reaction, making it possible to conduct accurate tests. It is possible to maintain a usable state for a long period of time. In addition, when the folded cup body is opened into a cup shape, the bottom part forms a roughly mountain-shaped shape, and the test piece is fixed at a position near the top of the bottom part, so that when the urine collected in the cup body is discarded, the inside of the cup body becomes Even if some urine remains on the test piece, the residual urine will inevitably collect at the bottom edge, that is, in a position that does not touch the test piece. flows along the slope of the mountain, i.e.
Therefore, the reaction of the predetermined test reagent applied to the test piece may proceed too much due to the residual urine, or it may mix with a different type of reagent eluted in the remaining urine, causing the reaction characteristics to change. It can reliably prevent urine from changing or reacting to components other than urine components.
This ensures that accurate tests are always performed, regardless of how the person conducting the test collects urine or how it is processed. Moreover, since the test piece to which the test reagent has been applied is placed at the bottom of the cup, a sufficient test can be performed even with a small amount of urine collected.

(F. Example) Below, details of the urinalysis cup of the present invention will be described according to Example 1 illustrated.

(a. Outline of urine test cup) [Figure 1, Figure 2, Figure 4,
Figure 's8] The urine test cup 1 consists of a cup body 2, test pieces 3 and 4 attached to the inside of the cup body 2, and a drying material 5, and the cup body 2 is made by laminating cardboard, metal foil, and synthetic resin film. It is formed from a sheet-like base material 6 made of a sheet, which is folded in advance and whose opening 7 is sealed, and can be opened into a cup shape after cutting out the opening 7. At this time, the bottom portion 8 forms a substantially mountain shape.

The test pieces 3 and 4 are applied with a predetermined indicator reagent that reacts with a predetermined pathological component contained in urine and indicates the presence or absence of the component and the amount thereof, and is attached to a mount 9. It is attached to the bottom 8 of the cup body 2 at a position near the top 8a.

The desiccant material 5 is used to dehumidify the inside of the cup body 2 so that the seals 3 and 4 do not absorb moisture and the reaction progresses.

To conduct a urine test using such a urine test cup 1, first, the sealed opening 7 of the cup body 2 is cut out as shown in FIG. 8(A), and then cut into a cup shape as shown in FIG. 8(B). Open the cup, then collect an appropriate amount of urine into the cup body 2, immediately discard the urine, and after a predetermined period of time, test piece 3.4.
While looking at the color, compare it with the color indications 11, 11, . . . or 11', 11', . This is done by reading the data shown for nearby colors.

(b, Cup body) [Figures 1 to 6, Figure 8] (b-1, Form before use) [Figures 1, 2] The cup body 2 is in a cup shape before use. When not unfolded, it is folded into a substantially rectangular sheet.

That is, 12.12' is a wall portion having a substantially rectangular shape, and these wall portions 12.12' have both ends 1 in the longitudinal direction.
3.13' are fixed to each other, and the ends 13.1
3' is a grip portion when the cup body 2 is used.

The bottom part 8 of the cup body 2 is folded in two along the width direction of the wall part 12.12' into two parts 14 and 14' (hereinafter referred to as "bottom piece"). 12'' has a length of approximately one-third of the length in the width direction of the wall portion 12. Continuous.

Further, each other end portion 12 along the width direction of the wall portions 12 and 12'
The space 7 between b and 12'b is the opening when the cup body 2 is opened into a cup shape, and this opening 7 is located between the wall parts 12 and 12'.
Sealing is achieved by fixing regions of the other ends 12b, 12'b having a certain width to each other.

There are several methods for achieving the above-mentioned seal, but in this embodiment, the base material 6 of the cup body 2 is formed so that one surface thereof has heat-fusible properties, and the one surface is are assembled so as to form the inner surface of the cup body 2, and are therefore sealed by heat-pressing the respective other ends 12b, 12'b of the wall portions 12, 12'.

The heat-compression bonding is performed using a plurality of sealing strips 15. which extend in parallel along the direction in which the opening surface of the opening 7 extends, that is, the direction perpendicular to the direction in which external moisture permeates into the opening 7.
15, . . . are formed by press molding. Therefore, as can be clearly seen from FIG. 1, the portion of the cup body 2 corresponding to the opening 7 has a substantially wavy shape.

Therefore, before use, the cup body 2 is folded thinly, and its interior is kept almost completely airtight and watertight.

It should be noted that the cup body 2 is provided with a material to enable the base material 6 to be neatly folded into a predetermined shape during the manufacturing process, or to enable the folded cup body to be easily opened into a cup shape. A perforated folding line is provided.

That is, there are folding lines 16.16, .
There is a folding line 17.1 in the continuous part between the wall part 12.12' and the bottom part 8.
7' is a fold between the two bottom pieces 14 and 14' of the bottom part 8, and a folding line 18 is formed approximately between the longitudinal midpoint of the wall part 12.12' and the grip part 14.14'. extending parallel to the gripping part 13.13' of the wall part 12.12' in an intermediate position;
And the folded line 19.19 is interrupted at a position near the opening 7.
, . . . , the sealing strip 1 of the wall portion 12.12'
Cutting lines 20 and 20 are provided at the boundary between the portion where 5.15, . . . are formed and the remaining portion, respectively,
Furthermore, a folding line is also provided at a predetermined portion of the bottom which will be described later.

In addition, these folding lines 16.16,..., 17.17.1
8, 19, 19, . . . and the perforation lines 20, 20, etc. are provided only on the outer sheet of the base material 6 made of cardboard, which will be described later.

(b-2, Form in use) [Figures 3, 4, and 8] The cup body 2, which is folded as described above before use, can be opened into a cup shape as follows. .

That is, first, as shown in FIG. 8(A), the seal strip 15 is
,15. Cut out the sealed portion along the cutting line 20.20, and then pinch the gripping portion 13.13' and remove the gripping portion 13, as shown in FIG. 8(B).
．． 13' are pressed inwardly toward each other. The walls 12, 12' are then spaced apart from each other and the bottom piece 1 of the bottom 8
4 and 14' open to form a substantially mountain shape, and the wall portion 12
．． 12' is bent into a substantially trapezoidal shape along the bending lines 19, 19, . . . in the thickness direction, respectively.
As a result, the cup body 2, which had been folded into a sheet shape, is now folded into the wall portion 12.12, as shown in FIG. 8(B).
It is deformed into a cup shape that is approximately hexagonal or elliptical when viewed from the direction along the width direction of '.

In addition, when opening the cup body 2 into a cup shape, the wall portions 12 and 12
' from the two folding lines 19.19 to the gripping part 13.13
13.' until the portions on the side face each other substantially parallel to each other.
When 13' is pressed, the cup body 2 is deformed into a shape in which the opening 7 becomes approximately circular and the bottom part 8 is flat. When the pressure is released, the cup body 2 returns to the hexagonal or elliptical shape due to the rigidity of the base material 6, so that the bottom portion 8 becomes chevron-shaped.

By opening the cup body 2 into a cup shape, the cup body 2 can be placed upright with its opening 7 facing upward.

When discarding the urine sample cup 1 after use, it can be returned to its pre-use shape, that is, the thinly folded shape, by pressing the wall portions 12, 12' together as necessary.

(b-3, Base material and its water impermeability, etc.) [Figures 1 and 5] The base material 6 constituting the cup body 2 consists of an outer sheet 21 and an inner sheet 22 that are laminated together, and the outer sheet 2
1 is about 180g/rr thick? It is made of cardboard or so-called board paper, which has relatively high rigidity, that is, has a strong shape retention ability.
Both surfaces or one surface serving as the outer surface of the cup body 2 is treated to have water repellency.

In addition, the inner sheet 22 has a multilayer structure in which metal foil and a large number of synthetic resin films are laminated.
3 is a metal foil with a thickness of approximately 9 microns, such as a rolled foil of aluminum (81); 24 is a synthetic resin film with a thickness of approximately 40 microns laminated on one side of the metal foil 23;
25, 26 and 27 are synthetic resin films laminated in sequence on the other side of the metal foil 23, and the thickness of these three synthetic resin films 25, 26 and 27 is the same as that of the metal foil 23.
Approximately 15 microns, 25 microns, 2 from the 3rd side.
It is 0 micron.

The types of these synthetic resin films 24, 25, 26 and 27 do not need to be specific; for example, polyethylene (PE), polypropylene (PP), polyester, brain cellophane (PT), polyethylene terephthalate (PET), nylon ( Single synthetic resins such as Ny), polyvinyldene chloride (PVDC), and vinyl chloride, or composite synthetic resins with these synthetic resins or multiple other synthetic resins, such as PT/PE, PVDC:) -)
-/PT/PE, PET/PE, PC (polycarbonate/PE, stretched PP/PE/PT/PE, PVDC/P
ET/PE, PVC/PE% PP/PVA/PE
.

Any material that is at least water-impermeable and flexible, such as PP/PV/PEDC, Ny/PE, etc., is sufficient, and it does not necessarily matter whether or not it is translucent.

Then, the synthetic resin film 27 forming the layer farthest from the metal foil 23 of the inner sheet 22 is attached to the outer sheet 22.
The cup body 2 is assembled such that the outer sheet 21 is located on the outside.

That is, the cup body 2 has a cardboard 21 as its outermost layer, and a synthetic resin film 27, a synthetic resin film 26, a synthetic resin film 25, a metal foil 23, and a synthetic resin film 24 are sequentially laminated from the cardboard 21 to the inside. It has a six-layer structure consisting of

Therefore, the cup body 2 is mainly composed of a synthetic resin film 24.
Water impermeability and air impermeability are maintained by 25, 26 and 27, and mainly the outer sheet 21 and the metal foil 23
This maintains light-impermeability, especially oxidant-blocking property, so that the interior becomes water-impermeable, air-impermeable, and light-impermeable before use, that is, before the opening 7 is cut open. It is completely retained, and the urine collected during use is prevented from penetrating the base material 6 and seeping out, and
The outer sheet 21 provides good shape retention in both the folded state and the cup-shaped opened state.

(b-4, Example of manufacturing process) [Figure 6] The cup body 2 made of such a base material 6 is manufactured, for example, as follows.

FIG. 6 shows the outer sheet 21 unfolded. In this unfolded state, the outer sheet 21 has a substantially rectangular sheet shape, and the center portion of the two side edges 28 and 28 extending along its longitudinal direction. A long cutout 29.29 is formed along the direction in which the side edge 28.28 extends, and a cutout hole 30.30 having a substantially right triangular shape is formed near the cutout 29.29. ing. And outer sheet 2
A perforation line 16.16 for folding extending along the longitudinal direction of the sheet 21 at a position closer to the polished side from the side edge 28.28 of the sheet 21 is formed between the mutually opposing ends of the notch 29.29. 17.1 A perforation line for bending that extends to connect the
7 are formed respectively, and the above two perforation lines 1
The part 31 between the right triangular notches 30 and 30 between the perforation lines 17 and 17 is the bottom part.
The portions 32 and 32 between the bottom portion 7 and the bottom portion 31 are folded portions. In addition, portions 33.3 of the outer sheet 21 located on both sides of the bottom portion 31 and the folded portions 32.32.
Reference numeral 3 denotes a wall portion, and cutting perforations 20.20 extending along the width direction of the outer sheet 21 are located at positions of the wall portions 33.33 closer to the polished side from both ends of the outer sheet 21 in the longitudinal direction. furthermore, this wall portion 33.3
A bending perforation line 19.19 is provided at a position approximately in the middle between the intermediate portion in the longitudinal direction of 3 and the perforation line 16.16.
... are formed, and these perforation lines 19, 19,
. . . is interrupted slightly before reaching the cutting line 20.20.

Incidentally, a bending perforation line 18 is also formed in the bottom portion 31 at an intermediate position in the longitudinal direction of the outer sheet 21.

Such an outer sheet 21 is made by punching out a paperboard material having an appropriate size and punching out perforations 16.1 at predetermined positions.
6.17.17.18.19.19, ... and 20,
20.

Then, the inner sheet 2 is attached to such an outer sheet 21.
2 are laminated, thereby forming the base material 6 of the cup body 2, and thus the outer sheet 2 of this base material 6.
The portions corresponding to the cutouts 29, 29 and 30, 30 of No. 1 consist only of the inner sheet 22.

Next, such a base material 6 is folded along folding perforations 17, 17 and 18 provided on the outer sheet 21. That is, the two wall portions 33.33 of the outer sheet 21 are bent with the perforation line 17.17 as a mountain fold line so that they face each other with the inner sheet 22 as the inner surface, and the perforation line of the bottom portion 31 of the outer sheet 21 is bent. Fold it in two using 18 as a valley fold line. Note that the folded portion 32 of the outer sheet 21.
32 is folded in half at the middle part where the width is the smallest, similar to the bottom part 31.

Next, the wall portion 33 of the base material 6 folded in this way
．． 33, the part from the perforation line 16.16 to the side edge 28.28 side and the part from the cutoff line 20.20 to the edge side are heat-sealed. As a result, the gripping portion 13 of the cup body 2.
13' is formed and the opening 7 is sealed. In addition, among the parts to be heat sealed, perforation line 17.
Most of the part near 17 is where the outer sheets 21 face each other, but in the part where the notch 29.29 of the side edge 28.28 of the outer sheet 21 is located, this notch of the inner sheet 22 Since the portions corresponding to portions 29, 29 are directly opposite, they are heat sealed by said portions of the inner sheet 22.

Further, the sealing of the portion along the perforation line 20.20, that is, the opening 7, is performed by forming the sealing stripes 15.15.15 extending along the direction in which the opening surface of the opening 7 extends, as described above. It will be done.

Thus, the cup body 2 whose interior is completely sealed is formed in a folded state.

(b-5, Moisture Permeability Test) In order to measure the moisture permeability of the cup body 2 whose interior was thus sealed, the following test was conducted.

That is, three types of specimens were prepared under different conditions: one filled with approximately 30 g of anhydrous calcium chloride and sealed, and one sealed with metal foil 2.
3 with a large number of pinholes formed, and before sealing the opening 4, it was opened into a cube shape, then folded again and filled with about 30 g of anhydrous calcium chloride, and the front end was sealed. Prepare 5 to 10 pieces each with the opening 7 sealed without filling, and
The weight was measured after leaving it for a day.

As a result, the amount of change in the weight of the specimen was +0.3 in each case.
Moreover, this increased weight of about 0.3 g is considered to be moisture absorbed by the outer sheet 21, and therefore, it was found that the penetration of external moisture into the interior of the cup body 2 is approximately zero.

(c, test piece) [Fig. 1, Fig. 2, Fig. 4, Fig. 8 (D
)] The test pieces 3 and 4 are made of a material with good permeability, for example, a filter paper coated with or impregnated with a predetermined test reagent and then dried. It is bonded to one side with an adhesive or adhesive.

These test pieces 3 and 4 are desirably placed at a certain distance from each other so that their reaction components, etc., do not dissolve into the collected urine and mix with each other.

In addition, the material of the mount 9 is a synthetic resin with good water repellency, for example,
It is desirable to use a sheet made of polyethylene, polypropylene, vinyl chloride, polyester, ethylene-vinyl chloride copolymer, etc., or a paperboard whose surface is coated with a highly water-repellent synthetic resin film. It is possible to prevent the collected urine from being absorbed by the mount 9 and causing the urine to unnecessarily accelerate the reaction of the test reagent 3.4.

Furthermore, this mount 9 is preferably white or white-colored,
If such a color is used, the reaction color of test piece 3.4 can be easily identified.

The test reagent applied to the test piece 3.4 is one that corresponds to the predetermined pathological component to be tested. That is, for sugar testing, for example, a reagent consisting of glucose oxidase/peroxidase/rhotolysine is used, and glucose in the urine is oxidized by the glucose oxidase, and the hydrogen peroxide produced at this time is converted into rhotolysine in the presence of peroxidase. It is conceivable to cause the color to develop by oxidation.

Furthermore, for protein testing, for example, tetrabromophenol blue or the like may be used so that the tetrabromophenol blue binds to albumin in urine and changes color.

Furthermore, for testing for occult blood, cumene peroxide/
It is conceivable to oxidize and color develop rhotrisine in the presence of peroxide and rhotrisine using a reagent such as rhotrisine.

For ketone tests, nitroprusid sodium changes color when it reacts with acetone or acetoacetic acid in urine, and for urobilinogen tests, p.
- Dimethylamine benzaldehyde reacts with urobilinogen and changes color, which can be used to test for bilirubin, and dichlorobenzenediazonium salt can couple with bilirubin to form a color, which can be used to test for pH. An appropriate acid or base indicator reagent such as methyl red or bromothymol blue may be used.

Note that the mount 9 to which the test piece 3.4 is pasted is adhered to the inner surface of the bottom 8 of the cup body 2 at least before the opening 7 of the cup body 2 is sealed. Most of it is glued to the inner surface of one bottom side 14 of the bottom part 8 in a direction extending along the height direction of the bottom part 8, and therefore,
When the cup body 2 is opened into a cup shape, the mount 9 is located at the bottom inside the cup body 2 in an inclined position with respect to the wall portions 12, 12', as shown in FIG.

Furthermore, as described above, the interior of the cup body 2 is completely impervious to water and light before use, and the desiccant material 5 is sealed, so that the opening 7 can be cut out. The humidity is close to zero and the test reagent is kept shielded from light until it is removed, so the test reagent is not deteriorated by moisture or light.

(d, dry material) [Fig. 1, Fig. 2, Fig. 7, Fig. 8 (A
), FIG. 8(B)] The desiccant material 5 is approximately disk-shaped and has the following three-layer structure.

That is, 34 is a moisture absorbing layer, which is made of, for example, a suitable pulp holding calcium chloride. In addition, 35 and 36 are non-hygroscopic layers that play an important role in manufacturing, and are made of highly water-impermeable synthetic resin, such as PE film (with a thickness of about 1
5 microns) and a PE film (thickness 12 microns), which is pasted on both sides of the moisture absorbing layer 34, and the drying material 5 is attached to the cup body 2 while having such a non-hygroscopic layer 35, 36. Non-hygroscopic layer 35.3 just before being encapsulated
6 is peeled off and enclosed in the cup body 2.

Therefore, moisture that has penetrated into the interior of the cup body 2 for some reason before use is absorbed by the desiccant material 5.

(e. Urinalysis procedure and action of the cup body, etc.) [Figure 8] Urinalysis using such a urine sample cup 1 is performed by, for example,
Do it as follows.

First, as shown in FIG. 8(A), the sealed portion of the opening 7 of the cup body 2 is cut out along the cutting lines 20 and 20, and then, as shown in FIG. 8(B), the gripping portion is cut out. 1
3.13' or by placing fingertips on each edge of the gripping parts 13.13' and pressing the gripping parts 13.13' toward each other. As a result, the boundary between the wall portion 12.12' and the gripping portion 13.13' forms a bending line 19.19,
..., the wall parts 12 and 12' are separated from each other in the thickness direction, and the bottom part 8 is opened so that the two bottom pieces 14 and 14' form a substantially mountain shape, and at this time, In the folded portions 32.32 of the outer sheet 21, the portions that were previously folded in half are opened laterally, and most of the wall portions 12.12' are folded at the folded lines 19.19, . It is deformed into a substantially trapezoidal shape when viewed from above.

As a result, the cup body 2 is opened into a cup shape.

After discarding the desiccant material 5, the urine is collected into the cup body 2 as shown in FIG. 8(C). The amount of urine to be collected is sufficient to immerse the test piece 3.4 in the urine, and it is sufficient that the top 8a of the bottom 8 is submerged in the urine.

In addition, when the amount of urine collected is small and the test piece 3.4 is not immersed in urine, the cup body 2 is moved so that the bottom part 8 forms a mountain shape as gentle as possible, as shown by the two-dot chain line in FIG. Then, if the gripping portions 13, 13' are further pressed inward so that the width of the opening surface of the opening 7 becomes wider,
As the mount 9 approaches a position more parallel to the bottom 8,
Test strip 3.4 can be immersed in urine.

Then, the collected urine is immediately discarded after a designated time, for example, 2 to 3 seconds, has elapsed after collection.

In this case, a certain amount of urine, such as urine attached to the inner surface of the cup body 2, will remain inside the cup body 2, but this remaining urine will be deposited between the bottom part 8 and the wall at the lowest end of the bottom part 8. Part 1
2.12' will gather at consecutive positions and accumulate here. Of course, the excess urine from the urine impregnated in the test piece 3.4 and the urine attached to the mount 9 are also drained and collected at the lowest position.

Therefore, even if some urine remains in the cup body 2, it will accumulate in a position where it does not come into contact with the test piece 3.4.
It is almost completely prevented that the components of the reagent applied to the test strip 3.4 are eluted into the urine, or that the reaction of the reagent progresses too much due to the remaining urine, and therefore, after the urine is discarded, There is no need to hold the cup 1 upside down, and the cup 1 can be placed upright in an appropriate location with the opening 7 facing upward.

Then, after a predetermined reaction time has passed after discarding the urine, the color of the test piece 3.4 and the judgment table 10 attached to the urine test cup 1 are determined.
The colors shown in 11.11, ... or 11', 11',
... and compare these colors 11.11, ... or 1
By reading the data shown for the color closest to the color of test piece 3.4 among 1', 11', . . . , the presence or absence and content of the test component can be known.

(G. Effects of the Invention) As is clear from the above description, the urinalysis cup of the present invention is folded before use, and the opening is sealed by a seal strip extending along the opening surface of the cup. A cup body whose bottom part is approximately mountain-shaped when opened, a test piece to which a test reagent is applied and fixed at a position near the top of the bottom part, and a desiccant material enclosed in the cup body. It is characterized by

Therefore, according to the present invention, the sealing of the opening of the cup body is performed by a sealing strip extending along the opening surface, that is, extending along the direction perpendicular to the direction of penetration of external moisture into the opening surface. As a result, the sealing effect is greater than when the opening is sealed using a large number of seal strips extending in the direction of penetration, and the opening is almost completely sealed, making the interior of the cup body impervious to water. In addition, moisture that previously existed inside the cup body or moisture that penetrated into the cup body for some reason after the opening was sealed will be absorbed by the desiccant material sealed in the cup body. . This can almost completely prevent the test reagents installed inside the cup from absorbing moisture and causing denaturation or reactions, thus prolonging the usable state in which accurate tests can be performed. Can be retained for a period of time.

Since the test piece to which the test reagent has been applied is placed at the bottom of the cup, the test reagent can be soaked in the urine by simply taking enough urine to collect only at the bottom of the cup. Therefore, even a small amount of urine can be sufficiently tested. This has a great clinical advantage in that even people with diseases related to urinary function can perform the test very easily, and it is also possible to collect urine when a short period of time has passed after urination or at the beginning of urination. Urine tests can be performed reliably and easily even when tests are performed in situations where the amount of urine collected must be small, such as when it is undesirable to do so.
Moreover, there is no risk of spilling the collected urine around.

Furthermore, when the folded cup body is opened into a cup shape, the bottom part forms a substantially mountain shape, and the test piece is fixed at a position near the top of the bottom part, so that the urine collected in the cup body can be discarded. Even if some urine remains inside the test piece, the residual urine will inevitably collect at the bottom edge, that is, in a position that does not touch the test piece, and will not stick to the test piece or be impregnated with the test reagent. The urine flows along the slope of the mountain, i.e.
Therefore, the reaction of the predetermined test reagent applied to the test piece may proceed too much due to the residual urine, or it may react by mixing with a different type of reagent eluted in the residual urine. It can reliably prevent properties from changing or reacting to components other than urine components.
This ensures that accurate tests are always performed, regardless of how the person conducting the test collects urine or how it is processed.

According to the urine test cup of the present invention, since it is folded before use, it does not take up much storage space and is easy to carry and transport. However, it is possible to perform accurate urine tests, and it can be used for a long time.

In the above embodiment, the cup body was formed from a base material consisting of an outer sheet made of cardboard and an inner sheet made of metal foil and a plurality of synthetic resin films. In addition to being able to maintain sufficient water impermeability or moisture resistance against
A cup body that is highly deformable and yet resistant to tension and shearing can be formed.

In addition, the desiccant material was made into a substantially thin plate shape, and the outer surface of the desiccant material was covered with an impermeable film. By doing this, moisture absorption of the desiccant material was prevented during the manufacturing process and storage of the desiccant material. can be prevented from progressing and therefore
It can be enclosed in a cup body while retaining sufficient moisture absorption function.

However, the materials and structures of the cup body and desiccant material in the present invention are not limited to those described above.
