Description

Description Lid-shaped reagent container for analytical reagents `` Technical field ''

TECHNICAL FIELD The present invention relates to a lid-like reagent container for an analysis reagent which can easily perform water quality analysis.

"Background technology"

Many of the simple water analysis methods employ colorimetry.

The colorimetric analysis method is widely used in the industry because the instrument used is small, lightweight, inexpensive, and the results are visible as colors and the measurement results are fast. . However, such colorimetric analysis requires chemical knowledge, technology, and experience because chemicals are used.

In addition, since many kinds of chemicals are used, it is necessary to prepare more than a few kinds of reagents and also to store them. Furthermore, in order to use the reagents, a balance for collecting required amounts, a weighing scale such as a measuring cylinder, a volume measuring instrument, and the like are required, and these are used for stirring and storing. Requires a lot of beakers and flasks.

For this reason, if water quality analysis is to be performed on-site, not only is it extremely difficult to perform operations such as fractionation of reagents, but in some cases water quality analysis becomes impossible.

Reagents for water analysis include liquid and powdered reagents. For liquid reagents, the reagents stored in glass or plastic bottles can be collected with the attached spots or built into glass or plastic bottles. There are methods such as dispensing with a spotted drop or dropping with an eye drop bottle.

On the other hand, powdered reagents are obtained by dispensing the reagent contained in a glass or plastic container with the attached lightweight spoon, or in some cases, once in a laminating bag, or at both ends. For example, there is a method in which a reagent packed in a soft plastic tube to which is welded is cut into a packaging material and added to the sample.

In addition, there is a case in which a liquid or powdered reagent for one dose is previously enclosed in the colorimetric cell itself made of transparent glass or transparent plastic.

By the way, when using two or more types of liquid or powder reagents that cannot be mixed and stored, it is necessary to store each in a separate package.When analyzing the sample, use each reagent according to the usage method. They must be separately injected into the water sample. Therefore, as the number of reagents increases, the analysis work becomes more complicated, and the user becomes confused if the operation method is different for each reagent.

On the other hand, it is conceivable that the automatic measurement is performed by automatically inputting the reagents by using a machine or the like. When there are many input reagents, the structure becomes complicated, and the storage method of the reagents is complicated as described above.

By the way, there is a method in which reagents that cannot be mixed and stored are stored separately and mixed easily when used. In other words, it is not the purpose of operating the reagent for analysis, but, for example, a glass ampule sealed with a liquid reagent is placed in a soft plastic tube together with other reagents, and when used, the glass ampule is broken by impacting the soft plastic. Some reagents are mixed together. There is also a method in which substances that cannot be stored if mixed together are separately placed in a double bag, and external pressure is applied during use to damage only the inner bag. However, such an operation method requires careful operation, and the operation method may be different depending on the purpose of use. Therefore, the user is confused by the operation procedure and method.

As described above, when performing the simple water quality analysis, the above-mentioned colorimetric analysis is used because the equipment used is small and lightweight, and it is inexpensive, and the results can be seen visually as colors, and the measurement results can be quickly obtained. However, due to the complexity of preparation and storage of reagents to be used and the operation of reagents, water quality analysis requires sufficient chemical knowledge and experience. There was.

"Best mode for carrying out the invention"

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 to FIG. 3 show an embodiment of a lid-like reagent container for an analysis reagent of the present invention.

As shown in these figures, the reagent container is configured such that the female screw part 2 of the lid body 3 is screwed into the thread part 19 of the transparent container body 15 which becomes a colorimetric cell, so that the lid body 3 becomes It is designed to be freely fit to.

In the center of the inside of the lid body 3, a groove for fitting a crescent-shaped cutter blade 9 of a cutter 8A, which will be described later, which is pushed up when the lid body 3 is tightened, is fitted. 1 is formed. Inside the lid body 3, chemical resistant film containers 4 and 5 containing different types of reagents are stored. In addition, when the film containers 4 and 5 are housed, they are in a state along the moving direction of the cutter 8A.

Here, each of the film containers 4 and 5 only needs to have high barrier resistance (moisture and oxygen) and high chemical resistance, and is composed of a laminated material having a multilayered Z composite structure.

Specifically, it has a four-layer structure of polyester (12) -polyethylene (15w) -aluminum (7) -polyethylene (25α) in order from the outside.

Furthermore, polypropylene, PET or the like can be used.

At the lower part of the film container 5, a protector 7 made of a soft material such as paper and a hard plastic cutter 8A are provided.

The protector 7 is for preventing the film containers 4 and 5 from being inadvertently torn by the cutout 8A. As shown in Fig. 2, the protector 7 is located at the center of the disk-shaped protector 7a. A protector hole 13 is formed, and a bent piece 18 is provided on the outer peripheral edge of the protector body 7a. Then, as described later, when the cutter 8A pushes up the protector main body 7a, the protector main body 7a bends from the fold 18a of the bent piece 18.

The cutter 8A has a disk-shaped cutter bottom 8a, as shown in FIG. The cutter bottom 8a is provided with a plurality of reagent passage holes 10 through which the reagents in the film containers 4 and 5 and the water sample in the container body 15 pass through the reagent passage holes 10 respectively. Are mixed while moving.

In addition, it is assumed that a plurality of protrusions 12 are provided on the lower surface side of the bottom 8a of the cutlet. In addition, a donut-shaped packing 11 whose diameter is slightly larger than that of the cutter bottom 8a is provided. When the cutter 8A is stored inside the lid body 3, the protrusions 12 of the packing 11 protrude against the inner surface of the lid body 3 so that the cutout 8A can be prevented from falling off. ing. Further, at the center of the cutter bottom portion 8a, a cutter tube portion 8 having a crescent-shaped cutting edge 9 at its tip and a plurality of slits 14 on its side surface is provided. .

On the other hand, a scale 16 is formed on the transparent container body 15, which is a reference position for the amount of water to be taken into the container body 15. The opening edge of the screw portion 19 of the container body 15 serves as the pedestal 17 of the packing 11, and the pedestal 17 is tightened by the lid body 3 so that the pedestal 17 becomes the lower surface of the packing 11. When it comes into contact with, the space between the pedestal 17 and the packing 11 is sealed, so that leakage of liquid to the outside of the container body 15 is prevented.

Next, a method of analyzing an analysis reagent having such a configuration using a lid-shaped reagent container will be described. In the following analysis method, the case of detecting the concentration of phosphoric acid (P〇4 ^{: i} ) in the sample will be described.

That is, water is injected up to the position of the scale 16 of the container body 15 which becomes a colorimetric cell. In this case, the water volume is about 25 m 1.

In this state, the container main body 15 is put into a cell box of a photoelectric photometer (not shown) that detects the concentration of the test water using light of a predetermined wavelength, and zeroing of the photoelectric photometer is performed.

Next, the container body 15 is taken out of the photoelectric photometer, and the lid body 3 is attached to the screw portion 19 of the container body 15. At this time, the film containers 4 and 5 of the lid body 3 respectively contain a powder reagent containing ascorbic acid and a 10% diluted sulfuric acid containing ammonium molybdate.

Then, the female thread 2 of the lid body 3 is engaged with the thread 19 of the container body 15. When the lid body 3 is tightened in this state, the pedestal 17 at the opening の of the screw part 19 of the container body 15 comes into contact with the lower surface side of the packing 11, and the force 8 A is applied. Push inside. Along with this, the bent piece 18 of the protector main body 7a bends from the fold 18a with the movement of the power meter 8A.

When the lid body 3 is further tightened in this state, the crescent-shaped cutting edge 9 of the cutter 8 A first breaks through the film container 5. As a result, 10% dilute sulfuric acid containing ammonium molybdate stored in the film container 5 is passed along the plurality of slits 14 formed on the side surface of the cutter cylinder 8 of the power meter 8A. Film container 5 leaks out.

When the lid body 3 is further tightened in this state, the cutter edge 9 of the cut-off 8 A breaks through the film container 4. As a result, the powder reagent containing ascorbic acid leaks from the film container 4. When the lid body 3 is further tightened from this state, the crescent-shaped cutter blade 9 of the cutter 8A fits into the groove 1, and the tightening of the lid body 3 stops.

In this state, when the container body 15 is overturned and agitated, and the reagent is sufficiently mixed with the test water, it reacts with P O — contained in the test water to give a so-called molybdenum blue color. Mix the reagent thoroughly with the sample, allow it to stand for 5 minutes, and then set the container body 15 on the photometer again. As a result, the test sample concentration is displayed in mg z 1.

As described above, in this embodiment, after injecting a predetermined amount of water into the transparent container body 15, the film container 4, in which the predetermined reagent is stored inside from the opening of the container body 15, When the main body 3 holding 5 is mounted by tightening, the cutter 8A is moved according to the tightening amount, the film containers 4 and 5 are pierced, and the reagents inside the film containers 4 and 5 are removed. Is released into the container body 15. Therefore, when analyzing the test water, the reagent can be mixed with the test water by tightening the lid main body 3 into the container main body 15 into which the test water has been injected. However, water quality analysis can be performed safely and accurately with simple operations.

In addition, only one lid body 3 is required for one analysis of the water sample, and there is no need to prepare a separate container for accommodating the liquid reagent and the like.

Furthermore, since the container body 15 serving as a colorimetric cell can be shared for all water samples, it can be used any number of times after washing, which is very economical.

Furthermore, since the base 17 comes into contact with the lower surface of the packing 11 to prevent leakage of the liquid to the outside of the container body 15, after the water quality analysis is completed, Even when it is not possible to dispose or wash the container body 15 and the lid body 3, it is possible to take it home with the lid closed and sealed.

Moreover, when using such a lid-shaped reagent container for an analytical reagent in an automatic measurement device, the container itself has the same shape, so that the mechanism can be simplified and the container can be stored in the automatic measurement device itself. Since there is no need to provide functions, the size of the device can be reduced.

In the above embodiment, the case where the lid body 3 is loaded with the two film containers 4 and 5 has been described. However, the present invention is not limited to this example, and the case where one film container 4 or 5 is loaded is used. Inspection of water samples is possible. That is, in the case of nickel measurement as an example, as in the above, water is sampled up to the graduation 16 position of the container body 15 serving as a colorimetric cell. In this state, the container body 15 is placed in the cell box of the photoelectric photometer set to a predetermined wavelength, and zeroing of the photoelectric photometer is performed as described above.

Next, remove the container body 15 from the photoelectric meter and display the reagent indicated by Ni. Is attached to the container body 15 in the same manner as above, and the lid body 3 is tightened. At this time, similarly to the above, the pedestal 17 at the opening edge of the threaded portion 19 of the container body 15 is pressed into the lid body 3 while the pedestal 17 is in contact with the lower surface of the packing 11. Along with this, the bent piece 18 of the protector body 7a bends from the fold 18a with the movement of the cutter 8A, and when the lid body 3 is further tightened from this state, the crescent shape of the cutter 8A The cutter blade 9 first breaks through the film container 4 or 5. As a result, the nickel coloring reagent (powder reagent mainly comprising dimethylglycoxime) contained in the film container 4 or 5 is supplied to a plurality of slits formed on the side surface of the cut-off cylinder portion 8 of the cutter 8A. 1 Leaks out of film container 4 or 5 along 4. When the lid body 3 is further tightened in this state, the crescent-shaped cutter blade 9 of 8 A cut-off is fitted into the groove 1 so that the tightening of the lid body 3 is stopped.

At this time, as described above, the pedestal 17 at the opening の of the screw portion 19 of the container body 15 comes into contact with the lower surface of the packing 11, and the space between the pedestal 17 and the packing 11 is sealed, Liquid leakage to the outside of the container body 15 is prevented. In this state, the container main body 15 is inverted and stirred, and the reagent is sufficiently mixed with the test sample, and then left for 10 minutes.

At this time, if the encapsulated reagent is a powder, it may remain in the film container 4 or 5, so that the container body 15 is sufficiently inverted.

Then, 10 minutes later, if the photometer is set again, the density can be read in mg / 1 unit.

In this embodiment, the case where the film container 4 and / or 5 is simply pierced by the movement of the cutter 8A accompanying the tightening of the lid body 3 has been described. However, the present invention is not limited to this example. Container 4 A spacer may be interposed between steps 5 and 5 so that the movement of the cutter 8A is moderated.

In other words, when two or more types of reagents are charged, the reaction time of the previously charged reagents may be required, and in this case, the cut-off by the spacer-8 A It is possible to know the degree of tightening of the lid body 3 as a touch, and there is no need to break through the film containers 4 and Z or 5 containing the next reagent during the reaction of the previous reagent.

4 to 6 show another embodiment in which the configuration of the cutter 8A is changed. In the drawings described below, the same parts as those in FIGS. 1 to 3 are denoted by the same reference numerals, and redundant description will be omitted.

The cutter 20 shown in these figures is made of, for example, 0.15 mm hard stainless steel. At the center of the bottom 21 of the cutlet 20 of the cutlet 20, a crown-shaped power cutter blade 22 is provided. This cutter blade tip 22 is composed of four blade pieces 23 with the center of the power cutter bottom 21 raised upward, and the inside of the four blade pieces 23 is raised and raised. A reagent passage hole 24 formed at the same time is provided.

Further, a flange portion 25 bent downward is provided on the outer periphery of the cutter bottom portion 21. The flange 25 enhances the rigidity of the cutter bottom 21.

In addition, the packing 11 attached to the lower surface side of the cutout 20 is slightly larger in diameter than the cutter bottom 21, and the center corresponds to the reagent passage hole 24 described above. A communication hole 13 is formed, and a projection 12 is provided on an outer peripheral portion thereof.

The lid-shaped reagent container for the analysis reagent having such a configuration is used as follows.

That is, insert the female screw 2 of the lid 3 into the screw 19 of the container 15. When the lid body 3 is tightened in the fitted state, the pedestal 17 of the container body 15 is pushed into the lid body 3 while the pedestal 17 of the container body 15 is in contact with the lower surface side of the packing 11 as described above. Along with this, the bent piece 18 of the protector main body 7a bends from the fold 18a with the movement of the power 8A.

When the lid body 3 is further tightened from this state, the cutter blade 22 of the cutter 20 first breaks through the film container 5. At this time, since the cutting edge 22 consists of four blade pieces 23, the film container 5 can be easily and reliably pierced.

As a result, the 10% diluted sulfuric acid containing ammonium molybdate stored in the film container 5 described above passes through the reagent passage hole 24 formed in the center of the container 20 through the reagent passage hole 24. 1 Move to the 5 side.

When the lid body 3 is further tightened in this state, the cutting edge 22 of the cutter 20 breaks through the film container 4. Also at this time, since the cutter blade tip 22 consists of four blade pieces 23, the film container 5 can be easily and reliably pierced.

As a result, the powder reagent containing ascorbic acid leaks out of the film container 4 described above. When the lid body 3 is further tightened in this state, the cutter body 22 of the cutter 20 fits into the groove 1 and the tightening of the lid body 3 stops.

In this state, as described above, the container body 1 5 by inverting stir and mix thoroughly reagent test water, P 0 ₄ ³ included in the test water - coloration reacts with the molybdenum Bull one Ru so-called To color. Then, mix the reagent with the test water sufficiently. After standing for 5 minutes, set the container body 15 on the photometer again, and the test water concentration will be displayed in mg Z 1.

As described above, in this embodiment, the cutting edge 22 is formed of a plurality of cutting pieces 23 formed by cutting and raising the center of the cutter bottom 21. Since the number of blades of the blade pieces 23 is plural, the film containers 4 and 5 can be easily and reliably pierced.

In addition, in this embodiment, the rigidity of the cutter bottom 21 is increased by providing the bent flange 25 on the outer periphery of the cutter bottom 21, thereby increasing the rigidity of the cutter bottom 21. This makes it possible to reduce the thickness of the plate, which can simplify manufacturing processes and reduce costs.

In each of the above embodiments, the cutter 8A, 20 is connected to the cover body 3 by tightening the cover body 3 in a state where the female thread 2 of the cover body 3 is engaged with the screw portion 19 of the container body 15. (3) Although the description has been given of the case where the cutters are pushed into the inside, the present invention is not limited to this example. For example, as shown in Fig. 7, the cutters 8A and 20 It can also be pushed into the body 3.

That is, a guide protrusion 31 having elasticity is provided on the outer periphery of the upper portion of the mouth portion 30 of the container body 15. On the other hand, on the inner surface side of the lid main body 3, locking grooves 32, 33 formed around the circumference and guide grooves 34, 35 formed along the axial direction of the lid main body 3 are formed. ing. When the guide projections 3 1 are fitted in the locking grooves 3 2, the lid body 3 is prevented from being pushed into the container body 15 side, and the lid body 3 is turned to lock each guide projection 3 1 By removing from the groove 32, the lid body 3 can be pushed in, and the above-mentioned cutters 8A and 20 can be moved.

Then, at the position where each guide projection 31 is guided by the guide groove 34 and fitted into the locking groove 33, the film container 5 is pierced by the above-mentioned cutouts 8A and 20. . At this time, the pushing of the lid body 3 is prevented by the locking groove 3 3, so that the lid body 3 is turned again to remove each guide projection 31 from the locking groove 33 so that each guide projection 31 is formed. The film container 4 is guided along the guide groove 35, and the film container 4 is pushed by the cutters 8A and 20 described above. Torn.

As a result, as described above, when two or more types of reagents are supplied, even if the reaction time of the previously supplied reagents may be required, the pushing of the lid body 3 by the locking grooves 3 3 is restricted. This eliminates the risk of breaking through the film containers 4 and / or 5 containing the next reagent during the reaction of the previous reagent.

At this time, the confidentiality between each of the locking grooves 32, 33 and each of the guide grooves 34, 35 and each of the guide projections 31 is such that each of the guide projections 31 having elasticity has its own. It is maintained by contacting the groove.
