Abstract

PURPOSE:To obtain a vessel which does not allow the content to leak out at the time of use and is dissolved or dispersed in water after the use, by a method wherein an inner sheet taking a longer time for dissolution or dispersion in water than an outer sheet is provided inside the outer sheet being excellent in water-solubility or water-dispersibility. CONSTITUTION:A vessel 1 for examination of urine has a pair of side wall parts 2 and a bottom wall part 3 provided between the lower end parts of the side wall parts, and an inspecting part 6 is provided on the inner surface of one of the side wall parts 2. A sheet material has a double structure of an outer sheet part 15 having a shape-maintaining prperty and water-solubility or water-dispersibility and a thin-film- shaped inner sheet part 16 taking a longer time for dissolution or dispersion in water than the above. At the time of use, a prescribed shape is maintained by the shape- maintaining property of the outer sheet part 15, while the inner sheet part 16 obstructs penetration of the content into the outer sheet part 15. When the vessel is put in water after the use, the outer sheet part 15 is dissolved or dispersed quickly by the water and the shape of the vessel is lost. Since the inner sheet part 16 is shaped in a thin film, the vessel is dissolved or dispersed when the shape-maintaining property of the outer sheet part 15 vanishes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable container used for urinalysis and the like, which retains a predetermined shape for a predetermined time during use and dissolves or disperses in water after use. is there.

[0002]

2. Description of the Related Art As a container used for collecting urine for urinalysis, there is conventionally a disposable paper cup or the like using waterproof paper. This paper cup has been molded into a predetermined cup shape in advance, or is usually folded flat.
There is a cup which has a predetermined cup shape when used.

On the other hand, due to recent advances in inspection technology, after a paper piece is put in urine as a sample in a container and the paper piece is impregnated with urine, the color of the paper piece is changed by a chemical reaction or the like after a certain time has elapsed. Under these circumstances, urinalysis test strips have been developed that can provide useful information on glucose metabolism, renal function, acid-base balance, urinary tract infection, and the like.

[0004]

The conventional urine test using a urine test strip is carried out exclusively in hospitals and other testing institutions. However, if the urine test strip becomes more widespread, mass-produced, and available at low cost, a simple test will be performed personally at home using the urine test strip.

In this case, there is a problem with the container used for urine collection and urinalysis. That is, since the conventional disposable paper cup uses water-resistant paper, if the urine is collected and urine is collected and then flown directly to a flush toilet or the like, the toilet bowl becomes clogged.
Therefore, the cup after use must be thrown away in a waste container or the like, and disposal after use becomes a problem. Further, not only paper cups for urinalysis but also cups used for beverages and other disposable containers have a problem of disposal after use.

In view of such conventional problems, the present invention has been made.
It is an object of the present invention to provide a container which has a predetermined shape-retaining property without leaking contents during use and can be easily dissolved or dispersed in water after use.

[0007]

The container according to the present invention has a shape-retaining property and is more soluble in water than the outer sheet portion 15 on the inner surface of the outer sheet portion 15 which is excellent in water solubility or water dispersibility. Alternatively, it is provided with a thin film inner sheet portion 16 having a long water dispersion time.

[0008]

[Operation] During use, the shape of the outer sheet portion 15 maintains a predetermined shape, and the inner sheet portion 16 which has a longer time for water dissolution than the outer sheet portion 15 prevents the contents from penetrating into the outer sheet portion 15. Block. If you put the container in water after use, the outer sheet part
Since 15 has water solubility and the like, it rapidly dissolves or disperses in water and loses its shape as a container. Further, since the inner sheet portion 16 is a thin film, if the outer shape of the outer sheet portion 15 is lost, the outer sheet portion 15 cannot maintain a constant shape by itself, and after the outer sheet portion 15 is dissolved or dispersed in water, it is dissolved. Or disperse.

[0009]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 to 5 show a first embodiment of a disposable urine test container 1 to which the present invention is applied. This urinalysis container 1 is provided with a pair of side wall portions 2 and a bottom wall portion 3 between the lower end portions thereof, as shown in the deployed state during use in FIGS. 1 (A) and 1 (B). And in the state before use, (A) (B) of FIG.
As shown in, a pair of left and right side edge adhesive parts 4 and an upper edge adhesive part
A pair of side wall portions 2 are adhered to each other at 5 to form a hermetically sealed shape, and are folded into a flat shape. In the urinalysis container 1,
An inspection section 6 is provided on the inner surface of the one side wall section 2.

As shown in FIG. 4, the pair of side wall portions 2 and bottom wall portion 3 are made of a single strip-shaped sheet material 7, and the center of the sheet material 7 is bent into a mountain shape to form a gather portion 8. At the same time, after bending both sides of the gather part 8 to form a pair of side wall parts 2, as shown in FIGS. 3A and 3B, the left and right side edges and the upper end edge are paired with the left and right side edge adhesive parts. 4 and the upper edge adhesion part 5 are adhered respectively.

In the side edge bonding portion 4, the gather portion 8 is interposed between the pair of side wall portions 2 in the portion corresponding to the gather portion 8, so that four sheet materials 7 are stacked. However, the other parts are double-layered. Further, the adhesive parts 4 and 5 may be adhered by any one of heat adhesion, heat welding, hot melt, water glue and the like.

On the upper end side of the side wall portion 2, the upper edge adhesive portion 5 is formed.
A perforation for the opening 9 and other cutout lines 10 are provided in the vicinity of and in parallel therewith. In addition, in each side wall portion 2, a valley fold line 11 and a mountain fold line 12 are formed in parallel with the side edge adhesive portion 4 in the vicinity of the pair of left and right side edge adhesive portions 4 and at a position which is located in the center side by a certain size. And the bottom wall portion 4 is also provided with mountain fold lines 13 so as to connect the mountain fold lines 12. In addition, this valley line 11,14, mountain line 12,1
No. 3 is when viewed from the outside of Container 1.

As shown in FIG. 5, the sheet material 7 has an outer sheet portion 15 having shape retention and water solubility or water dispersibility.
And a thin-film inner sheet portion 16 having a longer water dissolution or water dispersion time than the outer sheet portion 15. The outer sheet portion 15 is, for example, a water-soluble paper obtained by mixing cellulose fibers into fibrous carboxymethyl cellulose, a nonwoven fabric of pulp fibers, or a water-dispersed paper impregnated with or coated with a superabsorbent polymer. It has a shape-retaining property that does not cause any problem in handling 1, and if it is put into the toilet bowl of the flush toilet after urinalysis, it will be dissolved rapidly by the water in the toilet bowl in an extremely short time of about 30 seconds to 1 minute or It is supposed to be dispersed.

The inner sheet portion 16 is made of a water-soluble film such as a polyvinyl alcohol film, starch paste, and other materials to have a thickness of several .mu.
Even when urine 17 to be the subject is placed in 1, the urine can be sufficiently prevented from permeating into the outer sheet portion 15 side for a certain time required for the urine test, for example, about 1 to 5 minutes. When the outer sheet portion 15 side is dissolved or dispersed, the shape retention property is lost and the water in the toilet bowl flows and is dissolved or dispersed. In addition, the inner sheet portion 16 is a urine sample of the subject inside.
Since it is in direct contact with 17, it is necessary to select the material according to the inspection purpose so as not to adversely affect the subject.

The inspection unit 6 is formed by sticking an elongated strip-shaped test paper on the inner surface of the inner sheet portion 16 in the vertical direction, or by coating the inspection reagent in the vertical direction on the strip. As the test paper or the test reagent of the test section 8, a conventionally known test paper is used depending on the purpose of the test. For example, when measuring the specific gravity of urine, urine SG test paper impregnated with a polyelectrolyte and a pH indicator may be used.

Therefore, if various conventional test strips or test reagents are appropriately selected or combined, urine specific gravity, urine occult blood,
Urine pH (hydrogen ion concentration), urinary protein, urine kent body, urinary bile pigment, urine amino acid, bacteriuria, glucose, bilirubin, urobilinogen, nitrite, white blood cells, pregnancy, etc. can be tested. From these test results Information useful for health management can be obtained. Note that the outside of the side wall portion 2 may be printed with inspection items, inspection methods, inspection result determination methods, and the like that can be inspected by the container 1.

When urine is inspected using the container 1 having the above-mentioned structure, it is carried out as follows. That is, since the container 1 is in a folded state in which the opening 9 side is sealed by the upper edge adhesive portion 5 before use, the container 1 is first opened by cutting the upper side from the cut line 10. In this way, it is possible to reliably protect the inspection unit 6 consisting of test paper or inspection reagents, etc., so that the inspection unit 6 can be prevented from being contaminated, deteriorated, deteriorated, etc. It is convenient for paper. Of course, since there is no dust or other substance in the container 1, it can be easily stored. Moreover, since the container 1 is flatly folded before use, it is not bulky and is easy to store and handle.

After cutting from the cutting line 10 and opening it,
Open the opening 9 side to both sides by applying a force from the pair of left and right side edge adhesive parts 4 to the container 1, insert a finger into the container 1 and press the gather part 8 downward, and flatten the bottom wall part 3. Expand to become. Then, since the side wall portion 2 and the bottom wall portion 3 have the respective bent lines 11 to 14, the container 1 has approximately six or four openings 9 side as shown in FIGS. 1 (A) and (B) and FIG. It becomes a cup-like shape and is kept in that shape by the shape retention of the outer sheet portion 15, so that it can be placed on a flat place such as an object.

When the container 1 is expanded as shown in FIGS. 1 and 2, a predetermined amount of urine 17 is collected therein. At this time, the urine 17 is prevented from adhering to the outer sheet portion 15 of the container 1. Then, after the urine 17 is collected, if a predetermined time passes, the urine 17 reacts with the test strip or the test reagent of the test section 6, and the test strip or the test reagent changes. The change is read and compared with the determination standard to make the determination.
This makes it possible to perform urinalysis very easily, and the test results can easily provide useful information for determining glucose metabolism, renal function, acid-base balance, urinary tract infection, and other health conditions.

After the inspection is completed, the container 1 can be thrown into the toilet bowl of the flush toilet as it is. That is, the container
The outer sheet 15 of 1 has shape retention and is made of a water-soluble or water-dispersible material, so if it is put into the toilet after use, it will be dissolved or dispersed rapidly by the water in the toilet. Then, the shape of the container 1 is lost.

On the other hand, the inner sheet portion 16 is made of a material that has a longer time for water dissolution or the like than the outer sheet portion 15. However, since the inner sheet portion 16 has a thin film shape, the shape of the outer outer sheet portion 15 is maintained. If it loses its property, it cannot maintain a certain shape by itself, so that it can be made to flow into the waste water pipe together with the water flow in the toilet bowl.
Since the inner sheet portion 16 has water solubility and the like like the outer sheet portion 15, the inner sheet portion 16 dissolves or disperses during flowing and does not pose a problem in wastewater treatment.

Particularly, the thin inner sheet portion 16 is made of a material that requires time to dissolve in water, etc., and the inspection time is secured so that the urine 17 does not penetrate during the inspection. For the outer sheet portion 16 required for this, it is possible to freely select a material having a sufficiently large shape retention property and rapidly dissolving in water or the like. Such a disposable container 1
If you use, you can easily urine in the toilet at home,
Moreover, post-treatment of the container 1 after urinalysis can be easily performed, which is very convenient for self-diagnosis of health condition.

6 and 7 illustrate a second embodiment of the present invention. As shown in FIGS. 6 (A) and 6 (B), the container 1 of this embodiment has two crests 8 having different heights in the folded state.
The gather portion 8 having a and 8b is formed on the bottom wall portion 3 side, and the lower edge portion of each side wall portion 2 and the bottom wall portion 3 are attached to the lower edge adhesive portion 18
It is glued in.

According to this structure, since the gather portion 8 has the two ridges 8a and 8b, the area on the side of the bottom wall portion 3 becomes large and the volume of the container 1 can be increased. Since the mountain portions 8a and 8b of the gather portion 8 are vertically displaced, the thickness of the lower end side of the container 1 in the folded state can be reduced.

Therefore, the container 1 is stored in the stocker of the vending machine.
Put it in a laminated form in the part, and from the product delivery port the container
Even when 1 is dispensed and sold, the product dispense port of the vending machine can be made small, and the bulkiness can be prevented even when the container 1 is stored in a box or the like in a laminated form. On the other hand, at the time of use, the container 1 is expanded as shown in FIGS. 7 (A) and 7 (B), but since the lower edge adhesive portions 18 are along the lower ends of the side wall portions 2, the lower edge adhesive portions 18 are in contact with each other. And can be very stable when container 1 is placed on the object during inspection.

8 and 9 show a third embodiment. Unlike the first and second embodiments, the container 1 according to the third embodiment does not have the gathers 8 on the bottom wall 3 as shown in FIGS. Arc-shaped mountain line 19 at the lower end of part 2
Is included.

As shown in FIGS. 9 (A) and 9 (B), even when the simple container 1 is used as described above, the lower end portions of the side wall portions 2 are bent at the mountain fold lines 19 and the bottom wall portion 3 is removed. Since it will be formed, it can be sufficiently used. However, in this case, both ends of the bottom wall portion 3, that is, the lower end side of the side edge adhesive portion 4 are projected downward and easily fall when placed on an object, so hold them by hand when using. There is a need.

FIG. 10 shows a fourth embodiment. As shown in FIG. 10 (A), the container 1 of the fourth embodiment is provided with a protruding portion 20 protruding downward in an arc shape at the lower end of the side wall portion 2. In this case, when you open the container 1
As shown in FIG. 10 (B), it becomes easy to make the bottom wall 3 side relatively flat. Therefore, the stability is improved even when it is placed on an object, and there is no problem as in the third embodiment.

11 and 12 show a fifth embodiment. The container 1 of the fifth embodiment has a structure as shown in (A) (B) (C) of FIG.
The sheet material 7 is adhered by the vertical adhesive portion 21 to form a tubular shape, and the gather portions 22 are provided between both ends of the pair of side wall portions 2 and the upper edge adhesive portion 5 and the lower edge adhesive are attached to each other. Bonded at section 18. The lower edge adhesive portion 18 is bent and adhered to one side wall portion 2 side, and a mountain fold line is provided at the lower end portions of each side wall portion 2 and the gather portion 22.

In the case of the container 1 of this fifth embodiment, the entire area including the opening 9 can be expanded into a square tube shape as shown in FIGS. Since the part 3 can also be made flat, the stability when placed on an object is improved.

13 and 14 show a sixth embodiment. In the container 1 of the sixth embodiment, the side wall portion 2 has an inverted trapezoidal shape in the folded state as shown in FIG. 13, and the mountain fold line 19 and the protruding portion 20 have an arc shape at the lower end portion of the side wall portion 2. In addition, the cutoff line 10 at the upper end is formed in an arc shape.
Therefore, since this container 1 can be made into a shape close to a normal cup as shown in FIG. 14 when it is expanded to a use state, there is an advantage that it can be handled almost like a normal cup.

FIG. 15 shows a seventh embodiment, which is provided with a container body 23 which is preliminarily formed into a cup shape and a lid 24 which is detachably attached to this. Also in these second to seventh embodiments, the container 1 is made of the same material as that of the first embodiment, and the inspection section 6 is provided inside the container to enable urinalysis, and to wash with water after use. Can be flushed in the toilet.

FIG. 16 shows an eighth embodiment in which a curved edge portion 25 that bends outward is provided on the periphery of the opening 9 at the upper end of the container body 23. By doing so, the inner sheet portion 16 appears at the upper opening edge portion, so that when the urine 17 is collected, even if the urine 17 adheres to the upper opening edge portion, the outer sheet portion 15 immediately. It does not dissolve and is easier to handle.

In the embodiment, the container 1 for urinalysis was described in detail, but if the inspection unit 6 is replaced with another container, it can be used for various other inspections such as water quality inspection. In addition, it can also be used as a disposable container for drinking water without the inspection unit 6. Further, in each of the embodiments, the structure in which the opening 9 is sealed by the upper edge bonding portion 5 or the lid 24 before use is illustrated, but the invention is not limited to this, and the opening is formed beforehand. You may stay.

The sheet material 7 used for the container 1 is an outer sheet.
In addition to the two-layer structure of the sheet portion 15 and the inner sheet portion 16, three or more layers having different water dissolution times may be stacked. Furthermore, the test reagent may be applied to the inner peripheral surface of the inner sheet portion 16 via a neutral film or directly so that the inner peripheral surface of the inner sheet portion 16 itself has a test function.

[0036]

According to the present invention, the inner sheet of the outer sheet portion 15 having a shape-retaining property and excellent water solubility or water dispersibility has a water dissolving or water dispersing time longer than that of the outer sheet portion 15. Since it has a long thin-film inner sheet part 16, it has a certain shape retention property without leaking when used, and can be easily dissolved or decomposed with water after use, and after use of the container 1. Is easy to process.

Further, in the present invention, inside the inner sheet portion 16,
Since the inspection unit 6 for the object to be inserted therein is provided, the inspection unit 6 can easily perform various inspections for the object.

Further, in the present invention, since the opening 9 side is a sealing shape and can be opened at the time of use, there is no internal stain during storage, and in particular, the inspection section 6 can be protected from stains, deterioration, deterioration and the like. There are advantages.
