Description

This relates to a kit for collecting samples of building structures such as walls and ceilings to test for the presence of harmful materials, in particular, a kit for collecting samples of exterior wall materials to stably collect asbestos in an isolated state. It also relates to a method for collecting samples for testing harmful substances using the sample collection kit for testing harmful substances.

As an example of a conventional method for removing hazardous substances, a removal bag body is disclosed that includes a bag body having a storage opening with a peripheral flange formed around it and a hand insertion opening, and a glove portion extending from the hand insertion opening into the bag body, in order to inspect how much hazardous substance is attached inside the housing, and the removal bag body removes and stores the hazardous substance from a housing with the hazardous substance attached inside (see Patent Document 1). This method includes a connecting step of connecting the storage opening of the removal bag to the flat surface of the peripheral portion of the opening of the housing so that the peripheral flange is in intimate contact with the opening in a flat surface flush with the opening, a removal step of inserting a hand into the inside of the housing through the opening and manually removing the hazardous substances adhering to the back side of the peripheral portion of the opening, a storage step of storing the removed hazardous substances in the bag body, a removal step of cutting off the hazardous substance storage portion at the bottom of the removal bag in an airtight state, and a recovery step of collecting the remaining upper portion of the removal bag in an airtight state.

In Patent Document 1, a tool pocket 13 is provided on the inside of the bag body 10. The tool pocket 13 is formed by placing a sheet member against the inside of the bag body 10 and welding the lower part and both sides of the sheet member to the bag body 10, and is pocket-shaped with an open top (see Figure 3). The tool pocket 13 contains a tool (not shown) for peeling off the hazardous material 2, and removal work can be performed without having to take the tool outside the bag body 10 and the chimney 3.

Tokutei No. 6622474

However, when trying to create a structure that is less likely to scatter samples when collected from a collection target, including the conventional methods described above, the number of parts to be collected increases, which complicates the procedure and makes collection inconvenient. In addition, the large number of parts means that the sample scatters when the tool is collected after collection, and the structure does not function to prevent leakage after collection.

The present invention aims to provide a sample collection kit or collection method that reduces the number of parts in the sample collection kit to reduce complexity, allows for more reliable collection of samples without scattering during and after collection, and can be transported safely and easily while preventing leakage after collection.

The following solutions are being implemented to address the above issues:

(1) The sampling kit of the present invention comprises a sampling bag (1) capable of sampling a target surface of a structure, the upper half of the backing material (12) of the sampling bag being:
A one-piece attachment opening (13) is formed, which can be attached to a target surface of a structure when taking a sample, and which has an adhesive surface area that can be folded and self-sealed after the sample is taken and peeled off from the target surface to which it is attached ;
A sample collection kit for testing for harmful substances , comprising a ring-shaped collection port (1H) formed in approximately the center of the adhesive surface area and having a vertically and horizontally symmetrical shape,
The adhesive surface area of the attachment opening allows the sample collection kit to remain attached to the target surface of the structure via the attachment opening of the collection bag,
In a collection bag that has been attached to a collection surface and has samples taken from the collection port,
The sampling port (1H) after attachment is peeled off from the target surface after sampling and removed from the sampling surface, and then the attachment surfaces are folded (once or twice in a valley fold) to self-adhere by folding up and down, left and right, or diagonally (approximately symmetrically), and the folded sampling port (1H) is surrounded and sealed by the self-adhesive area of the attachment port.

A second, integrated tape that overlaps with this attachment opening may be added. In addition, a folding guide mark that is visible from the front may be displayed on the face material or attachment opening of the storage bag.

With this configuration, the attachment opening is symmetrical, so it can be folded symmetrically in the left-right, up-down, or diagonal directions. In addition, the attachment opening is a single piece that is connected in a ring shape without interruption, so it can be sealed reliably without dust leakage.

In addition, the adhesive surface that adheres to the collection surface and the second adhesive tape are of one piece, and are not divided into separate sides but are made of one piece of tape that is continuously configured in the shape of a "mouth", so there are no gaps.

(2) Any of the collection kits described above,
The device is characterized in that a vertically elongated collection bag (1) whose upper opening can be sealed and a tool-holding sheet (2) made of an internally permeable material and of the same size as the collection bag or smaller or larger than the collection bag are overlapped at a predetermined overlapping portion via a reinforcing material (3) with double-sided adhesive.

With this configuration, two bags are used and the collection tool is isolated inside a dedicated bag, so there is no scattering around the collection tool. In addition, the tool-holding sheet is made of a sheet material that can be penetrated internally, so cutting work on the target surface can be performed safely and reliably with the tool.

It is preferable that the reinforcing material has an interference function, the lower edge is an approximately horizontal straight line, and a line passing on or near this horizontal straight line is set as the second fold line (FL2).

(3) Any of the collection kits described above,
The tool-holding sheet (2) is a tool storage bag capable of accommodating tools, the lower side of which is arranged upside down as an opening that can be repeatedly sealed, and the upper half or upper end of the bag body is an attachment part,
The overlapping portion is characterized in that slits (1S, 2S, 3S) for passing through the tip of the tool are formed in the internal region of the overlapping portion, passing through the surface (11) of the collection bag, the reinforcing material (3), and the back surface (21) of the tool holding bag (2) at the same position.

With this configuration, a slit for passing tools through is formed inside the tool storage bag via the reinforcing material, and even if a tool passes through this slit, the bag sheet can isolate the worker.

(4) Any of the collection kits described above,
The tool-holding sheet (2) is characterized in that a striking cushioning material (4) for striking a striking tool is attached to the upper or lower surface of the component surface of the tool-holding sheet (2) at a striking position for striking a striking tool .

With this configuration, a slit for passing tools through is formed inside the tool storage bag via the impact interference reinforcement material, and even if a stored tool passes through this slit, the bag sheet can isolate the worker.

(5) The collection kit is characterized in that the collection bag after collection can be folded back at a first fold line (FL1), which is a symmetrical fold line of the collection port, and then repeatedly folded back at second and third fold lines (FL2, FL3) that are located below the first fold line and approximately parallel to each other, to be transformed into a roughly rod-shaped folded state.

With this configuration, the collection bag after collection can be repeatedly folded into a roughly rod-like folded state, which seals the collection port and protects the sample collection section (see, for example, Figures 10 and 13). By folding it into a rod-like state, it is easy to transport and accidents such as leakage of sample powder can be prevented.

(6) A sampling method using the sampling kit is a method for sampling a target surface of a structure, in which a sample is taken from the target surface by cutting or striking using a sampling kit for hazardous substance testing, the method comprising: forming an integrated attachment opening on the upper half of the back surface of a sampling bag for taking a sample from the target surface of the structure, the integrated attachment opening being made of an adhesive surface area which can be attached to the target surface of the structure when taking a sample, and which can be folded and self-sealed after the attachment surface is peeled off, and forming a ring-shaped sampling opening having a vertically and horizontally symmetrical shape formed approximately in the center of this adhesive surface area,
It consists of the following steps:
- Target surface attachment step: The attachment opening on the back of the collection bag is attached to the wall surface of a structure or the like so that the collection opening in the center of the attachment opening is positioned on the target surface.
Tool storage step: A cutting or striking tool required for collection is stored inside the tool storage bag through a bag opening provided on a part of the periphery of the tool storage bag. At this time, the cutting part or striking part at the tip of the stored collection tool is stored in a direction penetrating or approaching the slits 2S, 3S, and 1S.
- Sample collection step: With the adhesive surface still attached to the target wall surface, grasp the tool storage bag from the outside and operate the sampling tool stored inside so that the cutting part or striking part at the tip of the sampling tool passes through slits 2S, 3S, 1S and comes into contact with the sampling port, and a sample is collected into the sampling bag by cutting the surface to be sampled with the cutting part of the sampling tool or striking the surface to be sampled with the striking part of the sampling tool.
Tool collection step: The tools in the tool storage bag are collected from the bag opening to the outside of the bag. The bag opening during collection is preferably positioned vertically above the collection opening.
Peeling step: The attachment opening is peeled off from the target wall surface while a scattering prevention liquid consisting of water or an adhesive liquid is sprayed or misted on the peeling portion and its surroundings.
Sealing step: The attachment port consisting of the adhesive surface area peeled off from the wall surface is folded so that the sampling port (1H) overlaps approximately symmetrically up, down, left, right or diagonally, and the attachment surfaces are bonded together to self-seal.

The present invention provides a sample collection kit that reduces the number of parts required to reduce complexity, allows for more reliable collection of samples without scattering during and after collection, and can also provide a collection kit that can be safely and easily transported while still providing a leak-proof function after collection.

FIG. 13 is a rear view of the second folding step of the collection kit of Example 3 (c) and the final folding step (d).

1 to 10 are explanatory diagrams and usage diagrams of a collection kit of Example 1, Figs. 11 and 12 are explanatory diagrams of a collection kit of Example 2, and Figs. 13 to 15 are explanatory diagrams of a collection kit of Example 3. In each of the examples, the collection kit of the present invention is configured to include at least a collection bag 1 with an attachment opening for attaching the collection bag to the wall surface of a structure or the like to collect samples in the bag, and a tool storage bag 2 attached to the surface side of the collection bag via a reinforcing material 3 made of small pieces.

The collection bag is configured so that the attachment opening on the back side can be attached with an adhesive layer, and the center of the outer shape of the attachment opening is a collection opening 1H that is open in a circular or polygonal shape. This collection opening is formed by hollowing out a so-called "closed shape" that does not contact the outer periphery of the attachment opening and does not open around the shape of the collection opening inside the rectangular attachment opening. The collection opening of Example 1 has a closed shape of a small horizontally elongated rectangle that is approximately similar to the outer shape of the attachment opening (Figures 1, 4, and 9). The collection opening of Example 2 has a closed circular shape centered on the centroid of the outer shape of the attachment opening (Figures 11 and 12). The collection opening 1H of Example 3 has a closed shape of a horizontally elongated flat hexagon (Figures 13 and 14).

The attachment port and collection port of the present invention have a geometric shape that is line-symmetrical or point-symmetrical, and can be folded and bound at a predetermined symmetrical or parallel fold line. In other words, as shown in the left to right diagrams of FIG. 9, the left to right diagrams of FIG. 12, the top to bottom diagrams of FIG. 14, and the top diagram of FIG. 15, the attachment port is set to a shape that can be folded in a valley fold at a predetermined symmetrical or parallel fold line with the center or center line of the collection port as the symmetrical point or line so that the adhesive surfaces of the attachment port are in contact with each other, and the attachment surface is folded at the fold line indicated by the guide, so that the collection port can be folded and sealed in a sealed state.

When a sample of a wall surface of a structure is taken using the sampling kit of the present invention , the attachment opening 1H of the sampling bag 1 is attached to the target surface FC of the structure, such as the wall surface of the structure, as shown in Fig. 4. In this attached state, a tool is stored in the tool storage bag 2 as shown in Fig. 5, and a sample FS of the structure is taken in the storage bag by pressing or scraping the tip of the sampling tool against the target surface FC connected to the sampling opening while the sampling bag is attached to the wall surface as shown in Fig. 6.

When scraping or striking the collected sample, the periphery of the sampling port 1H is temporarily attached to the wall surface by the attachment port 13. This prevents the collected sample from scattering into the surroundings. Also, although the tip of the sampling tool comes into direct contact with the target surface FC from the sampling port 1H, the entire tool is contained within the tool storage bag, so the user of the tool does not touch the collected sample when using the tool, and the sample scraped from the wall surface does not scatter into the surroundings (Figure 6).

After the samples have been taken, the tools are removed from the tool storage bag. At this time, as shown in Figure 7, it is preferable to lift the tool storage bag so that the opening is positioned above the sampling surface FC and the surrounding adhesive surface FG to prevent the collected samples from scattering.

Then, as shown in Fig. 8, the attachment surface of the collection bag is peeled off and removed from the target wall surface of the structure while spraying the anti-scattering spray SG. After that, as shown in Fig. 9 (Example 1), Fig. 12 (Example 2), or Fig. 14 to Fig. 15 (Example 3), the attachment surface of the exposed attachment opening 13 of the collected collection bag that has been peeled off from the wall surface is folded in a valley fold along a predefined folding line, so that the adhesive surfaces of the attachment surfaces are bonded together, and the collection opening is self-sealed in the folded state. This self-sealing prevents the collected sample from scattering or spilling from the collection opening, and allows the collection bag in the collected state to be safely transported.

As a guide for self-sealing the collection port 1H after collection, it is preferable to display a fold line or guide for the fold point on the back surface or the periphery of the attachment surface of the collection bag (symbols FG and FL1 in Figs. 1, 2 and 9), or to form a notch, groove or step (13S in Fig. 11 or the inclined edge of the reinforcing material 3 in Fig. 13).

After the collection port 1H is self-sealed, the collection bag may be transported as is, or it may be folded repeatedly so as to wrap the remaining portion of the collection bag around the self-sealed collection port 1H, as shown in the right diagram of Figure 9, Figure 10 (Example 1), the dashed line arrow in the right diagram of Figure 12 (Example 2), or Figure 15 (Example 3). For example, by repeatedly folding the collection bag approximately parallel to the second and third fold lines, the collection bag after collection can be made into a compact shape.

Example 1
As shown in Figures 1 to 3, the collection kit of Example 1 has an attachment opening (13) made of an adhesive layer shaped like a "B" in the shape of a smaller horizontally elongated rectangular collection opening carved out of a large horizontally elongated rectangular interior at the upper back surface of the collection bag.

Before use, the attachment opening (13) is a large horizontally elongated rectangular attachment shape that is entirely covered with release paper (14). When attaching the attachment opening (13) to a wall surface, the release paper (14) is peeled off to expose the back side (Figure 4).

Furthermore, below the attachment opening and in the center of the surface of the collection bag, there is a slit 1S in the shape of a "horizontal straight line" for passing the tip of the tool through. A reinforcing material 3 made of double-sided tape in the shape of a horizontal rectangle and having a slit 3S of approximately the same shape is attached to cover the front side of this slit 1S in the center of the surface. Furthermore, a tool storage bag 2 in the shape of a vertical rectangle and having a slit 2S of approximately the same shape is attached to cover the front side of this reinforcing material 3.

In other words, the tool storage bag is attached to the front side of the center of the collection bag via a reinforcing material 3 made of double-sided tape, and slits 3S, 2S, and 1S of the same position and length are formed in the overlapping portions of the attached collection bag, reinforcing material, and tool storage bag (see Figures 1 and 3b).

After removing the tools from storage bag 2, the bag is folded back in the same direction along horizontal fold lines (FL1), (FL2), and (FL3) to self-seal the attachment opening and create a rolled up, collected storage bag (Fig. 10).

The collection method using the collection kit of Example 1 consists of the following steps:

- Preliminary step (Figure 4): Check that the collection port is sealed and remove the release paper covering the attachment surface.

- Target surface attachment step (Fig. 4): Attach the attachment opening of the collection bag to the target surface using the folding position indicator FG as a guide for adjusting the attachment position on the attachment surface.

- Tool storage step (Fig. 5): Place the tools in the tool storage bag and seal it.

- Sample collection step (Figure 6): The tool in the tool storage bag is grasped from the outside of the bag and manipulated, and the collected sample is scraped off from the collection area surrounded by the attachment surface with the tool and collected in the collection bag.

- Tool recovery step (Figure 7): The opening of the tool storage bag is raised above the collection area, and the tools are removed from the storage bag and recovered.

- Target surface peeling step (Figure 8): While spraying the spray adhesive onto the target surface, peel off the attached surface from the top, detaching the collection bag from the target surface.

- Sealing step (Figs. 9 and 10): With the mouth of the collection bag sealed, the collection bag and the tool storage bag are folded together with the attachment surface so that they fold over each other along the symmetrical line of the attachment surface shape, using the folding position indicator FG or the upper and lower edges of the attachment surface and the reinforcing material as guides for the folding position. In Example 1, a compact folded shape can be achieved by repeatedly winding around a substantially horizontal first folding line, a substantially parallel second folding line, and a substantially parallel third folding line in that order. Note that if air is sealed in the collection bag, the final folded shape may be one in which the bag is folded over only along the first folding line.

Example 2
In Example 2, the collection bag has a "rectangular outer shape and round cutout" type attachment opening at the top of the back surface, which is a horizontal rectangle with a small round collection opening cut out from the inside. A double-sided adhesive reinforcing material 3 is attached to the collection bag over the entire width direction at a position overlapping with the lower half of the attachment opening, and the reinforcing material 3 has slits 1S, 2S, and 3S in the center.

The slit 1S on the surface is formed by attaching a tool storage bag 2 to the front of the bag via a reinforcing material 3, and slits 3S and 2S of the same position and length are formed to overlap. The tool storage bag 2 of the second embodiment is set to a larger width and height than the collection bag 1, and the bottom side is a sealable bag opening 20 with an operating piece 20FS.

Example 3
In the third embodiment, the collection bag has a "rectangular outer shape and diamond cutout" type attachment opening, in which the inside of a horizontal rectangle is hollowed out to have a small horizontally elongated hexagonal collection opening shape, at the upper part of the back surface of the collection bag. Also, a slit 1S is provided below the attachment opening in the center of the front and back surfaces of the collection bag.

The slit 1S on the surface is formed by attaching the tool storage bag 2 to the outside of the bag via the reinforcing material 3, and the slits 3S and 2S are formed in the same position and length and overlap each other.

After removing the tools from the storage bag 2, the bag is folded diagonally along the fold lines (FL1) (FL2) indicated by the diagonal lines along the upper oblique side of the collection opening shape, and then folded back in the same direction along the horizontal fold line (FL3) along the side edge of the tool storage bag and the horizontal fold line (FL4) parallel to this, so that the attachment opening is self-sealed and the collected storage bag is in a rolled-up state (Figure 10). In addition, impact cushioning material 4 is attached to the surface of the tool storage bag.

The collection kit and collection method of the above embodiment can provide a collection bag that can achieve two things: the analysis results are not altered by the sampling method, collection is fundamentally easy, and it does not cause scattering.

In particular, in the embodiment, folding the "mouth" shaped tape simultaneously maintains the sealed state and reinforces the sealed collection bag.

The collection opening of the temporarily sealable wall-attached collection bag is so-called closed, and its entire circumference is framed by the annular adhesive surface of the one-piece attachment opening, which is an integral ring shape that is symmetrical from top to bottom and does not separate midway, making it possible to more reliably prevent scattering when collecting samples by cutting. Furthermore, the tape at the attachment opening can be folded up and down along the fold line after collecting the sample, thereby sealing the collection opening in a self-sealing manner. In particular, folding it symmetrically or point-symmetrically can create an even self-sealing state that does not easily peel off again.

The surface that is attached to the collection surface is not made of four pieces of separation tape, but is instead made by forming a single piece of packing tape into a ring shape with a certain width, such as a square, so there are no gaps that could cause sample leakage.

Attaching the tool storage bag to the front side also provides the effect of "triple" sheet shielding with a sealed outer adhesive bag. In addition, by being reinforced with reinforcing material 3 and tool cushioning material, the collection bag and collected samples can be protected.

In addition, the temporarily sealable wall-attached collection bag and the temporarily sealable tool bag are integrated by external bonding, making them easy to transport and handle, and after collection they can be stored in a compact form for each collection site for protection. In particular, because the two bags are used as one, there is no risk of scattering from the collection tools.

A double sheet provides shielding between the tools and the bags, and when combined with the reinforcing material between the bags, there is triple shielding between the bags and the workers' hands. This makes it easier to collect the bags, while also preventing scattering, making the collection process more efficient and preventing scattering.

The present invention is not limited to the above embodiment and can be modified in various ways. Combinations of elements, extraction of some elements, disassembly into parts, or an integrated configuration are also possible.
