Description

Inspection container

Technical Field

The present invention relates to a container which can be opened from a sealed state without removing a cap or a cap and can appropriately discharge a content, and more particularly, to an improvement of an inspection container used for inspection, diagnosis, and the like of a sample in the medical or pharmaceutical field.

Background

In genetic testing in the medical and pharmaceutical fields, a method for detecting the presence or absence of pathogenic bacteria in a sample collected from a human body is widely known.

Among these methods, a gene amplification method called LAMP, which is a method in which a gene DNA of a pathogen extracted is mixed with a predetermined reagent and incubated at a predetermined temperature to amplify a gene DNA to be detected, has attracted particular attention (Virus No. 54, pp.107-112, 2004). According to this method, the examination time is shortened as compared with the conventional genetic examination, and a large amount of amplified products can be obtained, whereby the presence or absence of a target genetic gene can be determined visually, and the examination can be simplified.

However, when a gene is amplified by this method, there are the following problems, particularly, when the amplified gene is a pathogenic bacterium having a risk of air infection similar to tubercle bacillus.

For example, in a process of extracting a target gene by mixing a sample containing tubercle bacillus with a predetermined reagent in an open container and heating the mixture at a constant temperature, the contents may be scattered without taking care of pouring the container, or tubercle bacillus may be scattered into the air from the mouth of the open container. In such a case, the examiner is at risk of being infected with tubercle bacillus, and the safety of the examiner cannot be ensured.

In order to avoid such a risk, a heat treatment or the like may be performed in a state where the container is sealed with a lid.

However, even in such a case, when the extracted target gene is to be ejected, the cover must be removed, and even a nozzle cap or the like for dropping an appropriate amount must be attached to the cover to eject the target gene, so that the inspector has a high chance of contacting with a pathogen, and the risk increases, and the inspector must go through a complicated process such as replacement of parts.

In order to eliminate such a replacement trouble, for example, a method of attaching a cap to the nozzle cap is considered.

However, in this case, the sealing performance between the container and the nozzle cap, and further the sealing performance between the nozzle cap and the cap must be kept constant, and the risk of leakage and the like increases with the increase in the number of components, and thus, it is necessary to raise the vigilance.

As described above, the safety of the examiner is not limited to the method of amplifying the gene by the LAMP method, but is a problem to be secured, and further, is not limited to the examination of the gene, and in general examination, it is an important subject to not only secure the safety of the examiner, but also eliminate a complicated process such as replacement of a cap or the like in the examination process, and to use both the sealing property of the examination container and the ease of extraction.

Disclosure of Invention

In view of the above circumstances, an object of the present invention is to provide an inspection container in which the sealing property of a container containing contents is ensured by a cap and the contents can be poured out without removing the cap.

An inspection container according to the present invention for solving the above problems is an inspection container for receiving and pouring out contents, and includes: a container body having a mouth portion formed therein; a cap attached to the mouth to seal the container body; and an opening cap attached to the lid, wherein the lid has a closing wall that closes the mouth, and the opening cap has a pouring port and a cutting portion that cuts the closing wall, and when the opening cap is attached to the lid, the cutting portion cuts the closing wall to enable pouring of the content.

According to the inspection container of the present invention having such a configuration, the container body containing the contents can be sealed by the lid.

This can prevent the scattering of pathogenic bacteria and the like during the examination, and ensure the safety of the examiner.

Further, when the opening cap is attached to the lid member, the closing wall of the lid member is cut at the cutting portion formed in the opening cap, whereby the contents contained in the container body can be poured out from the pouring outlet without removing the lid member.

Thus, the contents can be poured out without removing the cover member, thereby ensuring the safety of the examiner, eliminating the trouble of replacing the opening cap, improving the examination efficiency, and shortening the waiting time of the patient by faster examination.

Further, after the closing wall is cut, the cap is opened to minimize the diffusion of the contents, thereby ensuring the safety of the examiner and allowing a desired amount of the contents to be dispensed.

In the inspection container according to the present invention, the cutting portion may cut the closing portion by press-cutting.

With this configuration, for example, when the cap is attached to the lid member as a capping (plug) by fitting both, the blocking portion is press-cut and cut by the cutting portion simultaneously with the capping, whereby the blocking wall can be cut instantaneously, and the inspection can be performed more efficiently.

In the inspection container according to the present invention, the cutting unit may cut the closing wall by rotating while being pressed (pressed) against the closing wall.

With this configuration, since the closing wall is gradually cut, it is possible to ensure the safety of the inspector while avoiding sudden explosion of the contents due to a difference in pressure between the inside and the outside of the container.

In addition, by rotating the cutting, a tubular discharge path can be secured, and the contents can be reliably discharged.

In the inspection container according to the present invention, the opening cap may be attached to the lid member by screw-fitting, and the cutting portion may cut the closing wall when the opening cap is screwed in.

With this configuration, since the pressing force and the rotation generated by the screwing of the opening cap constitute the cutting force of the closing wall, the closing wall is cut with a constant cutting force, and stable cutting is realized, so that the safety of the examiner and a reliable pouring path can be ensured.

In addition, the inspection container according to the present invention may be configured to include a restricting mechanism that restricts a range of rotation to less than 360 degrees after the cutting portion starts cutting the closing wall, and the restricting mechanism may prevent a part of the closing wall from being cut so that the closing wall does not fall off.

With this configuration, for example, when the closing wall is cut by screwing the opening cap, the closing wall is cut by 360 degrees from the start of cutting by the cutting portion, and the rotation is completed, and the opening cap can be screwed to the lid member by the regulating mechanism. As a result, the cutting portion does not rotate once after the cutting is started, and an uncut portion in which a part of the closing portion is not cut is formed in a part of the closing portion. Thus, the entire periphery of the closing wall is cut and the closing wall is detached, so that the closing wall itself does not obstruct the pouring of the contents and the smooth pouring of the contents can be ensured.

In the capacitor according to the present invention, the closing wall may have a cut line in a peripheral edge portion thereof.

With this configuration, since the closing wall is gradually cut without inputting an excessive force, the cutting labor is reduced, and an accurate cutting line is formed, so that the pouring path can be reliably secured.

In the inspection container according to the present invention, the cutting portion may be provided in a region where the opening cap and the lid overlap each other without cutting the closing wall when the opening cap is attached to the lid.

With this configuration, when the opening cap is attached to the lid member, since the cut portion is formed in the region where the opening cap and the lid member overlap each other without directly cutting the closing wall, the inspection container can be integrally stored while ensuring a state where the container body is sealed by the lid member in a state where the opening cap is attached. This eliminates the need to manage the opening cap as a separate component, and facilitates handling.

In the inspection container according to the present invention, the opening cap may have a filter portion for filtering the content, and the filter portion may be provided at a position not in contact with the content in a state where the opening cap is attached to the lid member and the cutting portion cuts the closing wall to enable pouring of the content.

With this configuration, since the opening cap has the filter portion, the contents can be stored without being in contact with the filter portion before opening, and the contents can be filtered by the filter portion after opening, so that the desired substances can be extracted and the undesired substances can be removed.

Further, since the filter portion is provided at a position not in contact with the content in a state where the opening cap is attached to the lid member and the cutting portion cuts the closing wall to allow the content to be poured out, for example, in a state where the inspection container is erected, when the opening cap is attached to the lid member, the filter portion can be prevented from being in contact with the content until the filtering operation is performed.

This prevents problems such as clogging due to expansion of the filter unit caused by contact between the content and the filter unit before the filtering operation, and maintains the filtering function of the filter unit in an appropriate state until the inspection container is inverted and the filtering operation is performed.

According to the present invention, the sealing property of the container containing the content is ensured by the lid, and the content can be dispensed by cutting the closing wall of the lid without removing the lid by the opening cap attached to the lid.

Detailed Description

Hereinafter, preferred embodiments of the inspection container according to the present invention will be described with reference to the drawings.

Fig. 1 is a schematic front view showing an example of an inspection container according to the present embodiment. The inspection container 1 shown in fig. 1 is constituted by three members, i.e., a container body 2 for containing contents, a lid member 3 for sealing the container body 2, and an opening cap 4 attached to the lid member 3 in this order from the bottom in a state where the container 1 is upright.

These members can be produced by injection molding using, for example, polyolefin resin such as polypropylene and polyethylene, and thermoplastic resin such as engineering plastic such as polyacetal and polybutylene terephthalate.

Further, each member may be colored for the purpose of shielding light. Further, the contents may be transparent or translucent in color so that the contents can be visually recognized from the outside.

The detailed structure of each member will be described below.

Here, fig. 2 is a schematic front view of an inspection container according to the present embodiment in a state where a cap is not attached. Fig. 3 is a sectional view taken along line a-a of fig. 2. Fig. 4 is an enlarged cross-sectional view of a main portion of fig. 3 showing an enlarged portion surrounded by a broken line.

(Container main body)

As shown in the drawings, the container body 2 has a bottomed cylindrical container shape, and a storage portion 21 is provided below the container body for storing the contents, and a mouth portion 22 capable of injecting and discharging the contents is provided above the container body.

The storage portion 21 is formed to have flexibility and strength enough to allow the contents to be poured out by inverting the inspection container 1 and compressing it from the outside (see fig. 8).

Further, a knurl 211 forming a fine longitudinal rib on the outer peripheral side surface is provided on the upper side of the receiving portion 21, and further, a boundary between the receiving portion 21 and the mouth portion 22 is provided with: a flange portion 212 protruding in the outer circumferential direction; handle ribs 213 (four in the illustrated example) are suspended from the flange portion 212 (see fig. 2).

When the cap member 3 or the opening cap 4 described below is screwed, the knurl 211 and the grip rib 213 form a rotation stop, and thus, reliable screwing can be performed.

Next, the mouth portion 22 is opened on the upper surface side, and a screw thread 221 (see fig. 3) which can be screwed into the cap 3 described below is provided on the outer peripheral surface.

The upper end inner peripheral surface of the mouth 22 is formed with a conical surface so as to facilitate insertion of an inner peripheral cylindrical portion 33 formed in the cap 3 described below. Accordingly, for the same reason, a conical surface is also formed on the outer peripheral surface of the distal end of the inner peripheral cylindrical portion 33 of the cover 3. By both of them, smooth insertion of the lid member 3 into the container body 2 can be achieved.

The bottom surface of the container main body 2 is formed to be self-standing in a state where the inspection container 1 is erected. The inside of container body 2 is formed in a bottomed cylindrical shape, and the inner diameter is formed so as to gradually increase from the bottom surface of container body 2 toward mouth 22.

(cover member)

Next, in the examples shown in the figures, the cap 3 is a cylindrical member that can be attached to the mouth 22 of the container body 2, and has a closed portion 31 formed at the lower portion and a cylindrical portion 32 formed at the upper portion.

An inner circumferential cylindrical portion 33 is provided inside the sealing portion 31 so as to be flush with the inner circumferential surface of the cylindrical portion 32, and a closing wall 34 is provided inside the cylindrical portion 32.

The closing portion 31 is a portion screwed to the mouth portion 22 of the container body 2 and covering the mouth portion 22 of the container body 2. The outer peripheral side surface of the closing portion 31 is knurled (see fig. 2) to form a slip-proof rotation when screwed into the container body 2 or the opening cap 4, thereby achieving reliable screwing.

Further, a screw groove 311 paired with the screw thread 221 of the mouth portion 22 of the container main body 2 is formed in the inner peripheral side surface of the closing portion 31, and thereby the container main body 2 and the lid member 3 are screwed together (see fig. 3).

Further, in the present embodiment, the cap 3 is attached to the mouth 22 of the container body 2 by screw fitting, but the present invention is not limited thereto. For example, a protrusion may be formed on the inner periphery of the lid member 3, and a groove may be formed on the outer periphery of the mouth portion 22, thereby performing capping or the like by fitting both.

As shown in fig. 3, the inner circumferential cylindrical portion 33 is a cylindrical rib that is hung down from the inner surface of the top surface of the closing portion 31 and the inner circumferential surface of the cylindrical portion 32, and is formed concentrically with the closing portion 31. The conical surface is formed on the distal end outer peripheral surface of the inner peripheral cylindrical portion 33 as described above, whereby the insertion into the mouth portion 22 of the container body 2 is facilitated.

The outer diameter of the inner cylindrical portion 33 is formed to be the same as the inner diameter of the mouth portion 22 of the container main body 2 or slightly larger than the outer diameter of the inner cylindrical portion 33. Accordingly, the outer peripheral surface of the inner peripheral cylindrical portion 33 is in close contact with the inner peripheral surface of the mouth 22 of the container main body 2, whereby the sealing property of the container main body 2 by the lid member 3 can be secured.

Further, as shown in fig. 4, a semicircular seal projection 312 is provided on the entire circumference of the inner surface of the top surface of the closing portion 31 between the inner circumferential cylindrical portion 33 and the closing portion 31. When the container member 2 and the cap 3 are screwed together, the lower end side of the seal projection 312 abuts against the upper end surface of the mouth 22 of the container body 2.

Accordingly, the seal projection 312 presses the upper end surface of the mouth 22 of the container body 2 by the fastening torque in the vertical direction generated by the screw fitting, thereby ensuring reliable sealability of the container body 2 by the lid 3.

Next, the cylindrical portion 32 is formed in a cylindrical shape so as to stand from the top surface of the closing portion 31, and a thread 321 is formed on the outer circumferential surface thereof so as to be capable of being screwed into the below-described opening cap 4.

Further, a vertical rib-shaped regulating protrusion 322 (see fig. 2) formed as regulating means in axial symmetry at two left and right positions is provided on the lower side of the outer peripheral surface of the cylindrical portion 32. The restricting protrusion 322 functions as follows: the stopper functions as a restricting mechanism that restricts the range of rotation to less than 360 degrees after the cutting portion 431 formed in the below-described opening cap 4 starts cutting the closing wall 34. The restricting mechanism will be described later in detail.

As shown in fig. 3, a conical surface is formed on the inner peripheral surface of the distal end of the cylindrical portion 32. This facilitates insertion of the cutting tube 43 formed in the below-described opening cap 4.

Next, as shown in the figure, the closing wall 34 is a wall formed in a thin film shape in the vicinity of the substantially center of the inner peripheral side surface of the cylindrical portion 32.

Thereby, the upper side of the inner peripheral surface of the cylindrical portion 32 is separated from the inner peripheral surface of the portion located below the closing wall 34, and the mouth 22 of the container body 2 is closed when the cap 3 is attached. A V-shaped cut line 341 is formed in the peripheral edge portion of the upper surface of the blocking wall 34 so as to facilitate cutting at a cut portion 431 formed in the below-described opening cap 4.

In the example shown in fig. 3, the inner diameter of the cylindrical portion 32 is different between the upper side and the lower side of the closing wall 34. Specifically, the inner diameter Φ D1 on the lower side of the closing wall 34 is larger than the inner diameter Φ D2 on the upper side by an amount corresponding to the thickness of the closing wall 34.

The reason for this is as follows.

As described below, if a part of the closing wall 34 is not cut by the cut portion 431 of the opening cap 4 to form an uncut portion, the uncut portion becomes a hinge (ヒンジ). When the closing portion 34 is folded along the inner side wall of the cylindrical portion 32 with the hinge as an axis, the closing wall 34 can be sandwiched between the outer peripheral wall of the cutting cylinder 43 of the opening cap 4 and the inner side wall of the cylindrical portion 32, and a pouring path of the content can be reliably secured (see fig. 6).

With the structure of the lid member 3 as described above, the container body 2 can be sealed by screwing the lid member 3 to the mouth portion 22 of the container body 2.

Further, as described below, if the closing wall 34 is cut by the cutting portion 431 of the opening cap 4, a path for pouring out the contents is formed by connecting the upper side of the inner peripheral surface of the cylindrical portion 32 and the inner peripheral surface of the portion located below the closing wall 34, and the contents can be guided to the opening cap 4.

(opening cap)

Next, the opening cap will be described with reference to fig. 5 to 7.

Fig. 5 is a sectional view showing an example of the inspection container according to the present embodiment, in which the opening cap is attached without cutting the closing wall, and fig. 6 is a sectional view showing a state in which the closing wall is cut. Fig. 7 is a schematic cross-sectional view of the opening cap corresponding to the cross-section B-B in fig. 5.

As shown in these figures, the opening cap 4 is provided with a cap body 41, a nozzle portion 42, a cutting portion 43, and a filter portion 44.

The unsealing cap main body 41 is a portion screwed to the cylindrical portion 32 of the cover member 3 and covering the cylindrical portion 32 of the cover member 3. In the outer peripheral side surface of the opening cap body 41, longitudinal rib-shaped grip ribs 411 are formed at the left and right positions in axial symmetry, and when screwed to the lid member 3, they form a rotation-preventing slip to achieve reliable screwing.

Further, a thread groove 412 paired with the thread tooth 321 of the cylindrical portion 32 of the lid member 3 is formed on the inner peripheral side surface of the unsealing cap main body 41, whereby the unsealing cap 4 is screwed to the lid member 3 (see fig. 5).

Further, in the present embodiment, the unsealing cap 4 is attached to the lid 3 by screw fitting, but the present invention is not limited thereto. For example, a protrusion may be formed on the inner periphery of the opening cap 4 and a groove may be formed on the outer periphery of the lid member 3, thereby sealing the opening by fitting the both.

Here, in the example shown in fig. 5, when the opening cap 4 is attached to the cover member 3, the cutting portion 431 is provided in a region where the opening cap 4 and the cover member 3 overlap without cutting the closing wall 34 of the cover member 3. Specifically, after the start of the screw-fitting of the opening cap 4 and the cover 3, the cutting portion 431 abuts against the closing wall 34 of the cover 3 in a state where the cutting portion 431 does not cut the closing wall 34 of the cover 3 and the effective engagement of the screw-fitting of the opening cap 4 and the cover 3 is ensured.

Thus, when the opening cap 4 is attached to the cover 3, the cut portion 431 is formed in a region where the opening cap 4 overlaps the cover 3 without directly cutting the closing wall 34 of the cover 3.

As a result, even in the state where the opening cap 4 is screwed, the cutting portion 431 does not cut the closing wall 34 of the lid 3, and the state where the container body 2 is sealed with the lid 3 is secured, so that the inspection container 1 and the opening cap 4 can be integrally stored. This eliminates the need to manage the opening cap 4 as a separate component, and facilitates handling.

Further, a slit groove 413 (see fig. 5 and 7) is formed on the inner side of the bottom surface of the opening cap body 41 as a regulating means in an axially symmetric manner at both right and left positions. The notch groove 413 is a notch groove as follows: a right-angled triangular recess having a slope along the thread groove 412 formed on the inner side surface and a contact surface hanging down from the slope is formed at a position corresponding to the regulating protrusion 322 of the lid member 3 with the inner side of the bottom surface of the opening cap body 41 as a base point.

The notch groove 413 functions as a restricting mechanism for restricting the range of rotation to less than 360 degrees after the cutting member 431 starts cutting the closing wall 34 of the cover 3 together with the restricting protrusion 322 formed in the cover 3.

The restricting mechanism will be described in detail later.

Next, the nozzle portion 42 is formed in a cylindrical shape so as to be erected from the top surface of the opening cap body 41, and a spout 421 in which a small hole through which the content can be poured is formed at the upper end portion thereof.

By forming the pouring outlet 421, the amount of the content to be poured can be finely adjusted, and the diffusion of the content due to the scattering to the outside or the like can be minimized, thereby ensuring the safety of the examiner.

Next, the cutting tube 43 is formed in a bamboo gun shape which hangs down from the inner surface of the top surface of the opening cap body 41, forms a cylindrical ridge concentric with the opening cap body 41, and cuts the cylindrical shape obliquely upward with the lowermost end as a base point.

Further, a cutting portion 431 having an acute-angled slope is provided at the distal end of the cutting cylinder 43 so as to cut the closing wall 34 of the cover 3.

Further, the closing wall 34 of the cover 3 is cut by the cutting portion 431 as follows.

Further, the outer diameter Φ D3 of the cutting cylinder 43 is formed slightly larger than the inner diameter Φ D2 of the cylindrical portion 22 of the cap 3. Accordingly, the outer peripheral surface of the cutting cylinder 43 is closely attached to the inner peripheral surface of the cylindrical portion 32 of the cap 3 without a gap, and the content can be guided to the spout 421 while avoiding leakage of the content. Further, as described below, the effect of facilitating the cutting of the closing wall 34 of the cover 3 by the cutting portion 431 can also be achieved.

Further, similarly to the sealing projection 312 formed on the lid member 3 shown in fig. 4, a semicircular sealing projection 414 is provided on the entire circumference of the inner surface of the top surface of the opening cap body 41 between the cutting cylinder 43 and the opening cap body 41. In the seal projection 414, if the cap 3 and the opening cap 4 are screwed, the lower end side of the seal projection 414 abuts on the upper end surface of the cylindrical portion 32 of the cap 3.

Accordingly, the sealing protrusion 414 is pressed and brought into close contact with the upper end surface of the cylindrical portion 32 of the cap 3 by the tightening torque in the vertical direction generated by the screw fitting, and the content can be reliably guided to the spout 421 without leaking.

The filter unit 44 is provided near the spout 421 on the inner peripheral surface of the nozzle 42. The material of the filter unit 44 is not particularly limited as long as it is inactive with respect to the substance to be analyzed. Specifically, there are exemplified a porous material such as a polyurethane sponge, polypropylene, polyethylene, polyester, or filter paper, a fibrous material such as glass wool or absorbent wool, or the like. Preferably, a glass wool filter having a predetermined pore size or a membrane filter made of a material such as polypropylene, cellulose acetate, regenerated cellulose, polycarbonate, or PTFE is used.

The filter unit 44 may have one type of structure, or may be formed by stacking two or more types of filters. In addition, a material having low adsorptivity is suitably used for the filter for aseptic filtration.

By providing such a filter unit 44, it is possible to filter the contents, extract desired substances, and remove unnecessary substances.

Further, since the filter portion 44 is provided in the vicinity of the spout 421 in the inner peripheral surface of the nozzle portion 42, the opening cap 4 is attached to the lid 3 in a state where the inspection container 1 is upright, and the filter portion 44 does not contact the content in a state where the blocking portion 34 of the lid 3 is cut by the cutting portion 431 so that the content can be poured out. This is because the filter portion 44 is prevented from coming into contact with the contents before the filtering operation is performed. This prevents problems such as clogging due to swelling of the filter unit 44 caused by contact between the content and the filter unit 44 before the filtering operation, and can maintain the filtering function of the filter unit 44 in an appropriate state until the inspection container 1 is inverted and the filtering operation is performed.

(cutting of the blocking wall)

Next, the cutting of the closing wall 34 of the cover 3 by the cutting portion 431 of the opening cap 4 will be described with reference to fig. 5 and 6.

As shown in fig. 5, first, the cutting cylinder 43 of the opening cap 4 is inserted into the cylinder portion 32 of the cover member 3. As described above, since the insertion is performed while being guided by the conical surface formed at the cylindrical portion 32 of the cover member 3, the insertion is easy.

Next, the screw tooth 321 of the lid member 3 and the screw groove 412 of the opening cap 4 start to be screwed, and the opening cap 4 is relatively moved downward while being rotated (screw movement).

Further, in a state where the opening cap 4 is moved downward and effective engagement of the screw opening cap 4 and the cover 3 is ensured, the cut portion 431 of the opening cap 4 abuts on the upper surface of the closing wall 34 of the cover 3. Specifically, the inclined surface of the cut portion 431 of the cap 4 formed at an acute angle is in contact with the cut line 341 of the closing wall 34 of the cover 3 formed in a V shape so as to be fitted.

Further, as shown in fig. 6, by screwing, the cutting portion 431 of the cap 4 is rotated while being pressed against the closing wall 34 of the cover 3, thereby cutting the closing wall 34 of the cover 3 along the cut-out line 341.

Thus, a certain fastening torque vertically acting by the screw fitting is transmitted to the closing wall 34 of the cover 3, the cut portion 431 of the cap 4 stably presses the closing wall 34 of the cover 3, and the closing wall 34 of the cover 3 is gradually cut by the rotation of the cut portion 431 of the cap 4. Therefore, the rapid burst of the contents due to the difference in pressure between the inside and the outside of the container can be avoided, and the safety of the inspector can be ensured.

Further, since the cutting portion 431 of the cap 4 is rotated and cut along the cut line 341 of the cover member 3, the cutting can be performed without inputting an excessive force, thereby reducing the cutting labor, and the tubular discharge path can be secured by forming an accurate circular cutting line, and the contents can be reliably discharged.

Further, as described above, the outer diameter Φ D3 of the cutting cylinder 43 of the cap 4 is formed larger than the inner diameter Φ D2 of the cylindrical portion 32 of the cap 3. This not only improves the adhesion between the outer peripheral surface of the cutting cylinder 43 of the cap 4 and the inner peripheral surface of the cylindrical portion 32 of the cover member 3, but also has the effect of facilitating the cutting of the closing wall 34 of the cover member 3 by the cutting portion 431 of the cap 4.

Specifically, since the outer diameter Φ D3 of the cutting cylinder 43 of the cap 4 is formed larger than the inner diameter Φ D2 of the cylindrical portion 32 of the cap 3, if the cutting cylinder 43 of the cap 4 is inserted into the cylindrical portion 32 of the cap 3, the closing wall 34 of the cap 3 is pulled toward the inner side wall surface of the cylindrical portion 32 of the cap 3, and the diameter of the closing wall 34 of the cap 3 is deformed in an enlarged direction.

Thereby, the wall thickness of the closing wall 34 of the cover 3 in the apex of the V of the cut-back line 341 of the cover 3 becomes thinner, and once cutting is started, it acts to promote cutting, so that cutting by the cutting portion 431 of the cap 4 becomes easy.

As described above, by cutting the closing wall 34 of the cover member 3 with the cutting portion 431 of the cap 4, the upper side of the inner peripheral surface of the cylindrical portion 32 of the cover member 3 is continuous with the inner peripheral surface of the portion located below the closing wall 34 of the cover member 3, thereby forming a path for pouring out the contents. At the same time, the closing wall 34 of the lid member 3 closing the mouth 22 of the container body 2 is opened, and the sealed state of the container body 2 is released.

Accordingly, the inner side wall of the container body 2, the inner side wall of the lid member 3, and the inner side wall of the opening cap 4 are all connected to each other, so that the pouring path to the pouring outlet 421 of the opening cap 4 can be secured, and the content can be poured from the pouring outlet 421.

As described above, even when the sealed state of the container body 2 is released and the content can be extracted by providing the filter portion 44 of the opening cap 4 near the spout 421 of the opening cap 4 in the inner peripheral surface of the nozzle portion 42 of the opening cap 4, the filter portion 44 of the opening cap 4 does not come into contact with the content in a state where the inspection container 1 is upright.

This prevents problems such as clogging due to swelling of the filter unit 44 of the opening cap 4 caused by contact between the content before the filtering operation and the filter unit 44, and maintains the filtering function of the filter unit 44 in an appropriate state until the inspection container 1 is inverted and the filtering operation is performed.

Further, the filtering operation of the filter portion 44 using the opening cap 4 is as follows.

(restricting mechanism)

Next, the restricting mechanism will be described with reference to fig. 6 and 7.

As described above, the restricting mechanism includes the restricting projection 322 of the cover 3 and the notch groove 413 of the opening cap 4, and is configured to restrict the range of rotation of the cutting portion 431 of the opening cap 4 to less than 360 degrees after the cutting portion 431 of the opening cap 4 starts cutting the closing wall 34 of the cover 3.

The restricting mechanism functions to restrict the rotation of the opening cap 4 at the final stage of screwing when the opening cap 4 is screwed to the lid member 3.

Specifically, after the cutting portion 431 of the opening cap 4 starts cutting the closing wall 34 of the cover 3, the cutting portion 431 of the opening cap 4 is further rotated to advance the cutting of the closing wall 34 of the cover 3. Thereafter, when the cutting portion 431 of the opening cap 4 rotates from the start of cutting to a position where the rotation range of the cutting portion 431 of the opening cap 4 is less than 360 degrees, the vertical abutment surface of the notch groove 413 formed in the opening cap 4 abuts against the side surface of the regulating protrusion 322 of the cover 3.

Thus, since the regulating mechanism regulates the rotation of the cut portion 431 of the cap 4, the cutting of a part of the closing wall 34 of the cover 3 by the cut portion 431 of the cap 4 is inhibited, and an uncut portion where a part of the closing wall 34 of the cover 3 is uncut is formed in a part of the closing wall 34 of the cover 3.

As a result, the uncut portion functions as a hinge of the closing wall 34 of the lid 3, and as shown in fig. 6, the closing wall 34 of the lid 3 is accommodated so as to be sandwiched between the outer peripheral wall of the cutting cylinder 43 of the opening cap 4 and the inner side wall of the cylindrical portion 32 of the lid 3.

Thus, the reason why the closing wall 34 of the cover 3 is housed is: the closing wall 34 of the lid member 3 is pushed downward by the cut portion 431 of the opening cap 4, and is poured toward the inner side wall of the cylindrical portion 32 of the lid member 3 with the uncut portion as an axis (hinge); and the inner diameter of the cylindrical portion 32 of the cap 3 is, as described above, different in the amount of thickness of the closing wall 34 of the cap 3 in the lower side (Φ D1) and the upper side (Φ D2) of the closing wall 34 of the cap 3(Φ D1 > Φ D2).

Thus, the blocking wall 34 of the cap 3 is detached, whereby the blocking wall 34 of the cap 3 does not interfere with the pouring of the content itself, and the smooth pouring of the content is ensured.

Further, the restricting means is not limited to the structure of the restricting projection 322 of the lid member 3 and the notch groove 413 of the opening cap 4, and for example, as described above, the restricting means may be formed such that the sealing projection 414 formed on the inner surface of the top surface of the opening cap body 41 abuts against the upper end surface of the cylindrical portion 32 of the lid member 3 by screwing the lid member 3 and the opening cap 4.

(discharge of Contents)

The pouring of the contents contained in the inspection container 1 according to the present embodiment will be described with reference to fig. 8.

Fig. 8 is a schematic cross-sectional view showing a pouring state of the content of an example of the inspection container in the present embodiment. The content M contained in the container body 2 is a mixed sample solution containing genetic DNA of pathogenic bacteria.

First, as described above, the opening cap 4 is attached to the lid member 3 in a state where the inspection container 1 is upright. Thereby, the closing wall 34 of the lid member 3 is cut off, and a pouring path of the content M to the pouring outlet 421 of the opening cap 4 is secured. In this state, as described above, the filter portion 44 of the opening cap 4 is not in contact with the content M. Thus, the filtering function of the filtering portion 44 of the opening cap 4 is maintained as appropriate until the filtering operation.

As shown in the figure, the filter portion 44 of the opening cap 4 starts to come into contact with the content M by inverting the inspection container 1. At this time, by the filtering function of the filtering portion 44 of the opening cap 4, unnecessary substances in the content M are filtered by the filtering portion 44 of the opening cap 4 and only necessary substances can be extracted. Further, by compressing the container body 2 by an external force, only a substance necessary for pouring a predetermined amount of the content M can be dropped from the spout 421 of the opening cap 4.

Further, the necessary substance in the content M can be guided to the spout 421 of the opening cap 4 without leakage due to the sealing property of the connecting portion of the members.

As described above, according to the inspection container of the present embodiment, the container body 2 containing the contents can be sealed by the lid 3, and the safety of the inspector can be ensured by preventing the scattering of pathogenic bacteria and the like during inspection.

Further, when the opening cap 4 is screwed to the lid member 3, the closing wall 34 of the lid member 3 is cut by the cutting portion 431 formed in the opening cap 4, whereby the contents contained in the container body 2 can be poured out from the pouring outlet 421 of the opening cap 4 without removing the lid member 3.

This enables the contents to be discharged without removing the cap 3, thereby ensuring the safety of the examiner, eliminating the need to replace the cap 4, improving the examination efficiency, and shortening the waiting time for the patient by making the examination faster. Further, after the closing wall 34 of the lid member 3 is cut, the opening of the cap 4 minimizes the spread of the contents, so that the safety of the examiner can be ensured and a desired amount of the contents can be dispensed.

While the preferred embodiments of the present invention have been shown and described, it is obvious that the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention.

For example, in the above embodiment, the attachment of the opening cap 4 to the lid member 3 is screw-fitted, and the cutting portion 431 of the opening cap 4 cuts the closing wall 34 of the lid member 3 by screwing the opening cap 4, but as described above, the attachment of the opening cap 4 to the lid member 3 may be capped and the cutting portion 431 of the opening cap 4 may be pressed against the closing wall 34 of the lid member 3 to cut the same. Thus, the blocking wall 34 can be cut off instantaneously, and the inspection can be performed efficiently.

As described above, the container for inspection according to the present invention can be used in a gene amplification method such as a PCR method and other genetic detection methods, immunoassay by an immunoassay method, microbial inspection, and the like, as well as in the medical and pharmaceutical fields, and also in the chemical field, and is widely used as a container capable of performing rapid inspection while ensuring safety of an inspector.
