Description

The present invention relates to a laying material-containing bag that stores laying material such as gravel and wood chips.

When laying gravel on the ground of a construction site (construction target site) such as a garden, passage, and garage, if the gravel is laid directly on the soil, weeds may grow between the gravel. In order to prevent such weeds, a weed-preventing sheet (sheet under gravel) is used (see, for example, Patent Document 1).

When laying gravel on a construction site, a worker (user) first prepares a weed proof sheet and gravel.

Weed-proof sheets and gravel are available at home improvement centers, for example. The weed proof sheet is sold in a rolled state, and the gravel is sold as a gravel bag by packing a predetermined amount in a storage bag such as a vinyl bag. The worker purchases a weed-proof sheet of a required length (area) and a required number of gravel bags according to the area of the construction site.

Next, the worker spreads the weed-proof sheet on the entire ground at the construction site. Next, tear the gravel bag, take out the gravel from the inside, and lay it over the entire surface of the weed-proof sheet. At this time, the gravel is laid so as to have a uniform thickness (depth) over the entire surface of the weed control sheet.

However, according to the conventional technology, there is a problem that a storage bag (gravel bag) that has been emptied by removing gravel is discarded without being used for resource saving.

In addition, since the gravel is laid on the entire surface of the construction site after laying the weed proof sheet, it is difficult to lay the gravel to a uniform thickness over the entire surface.

The above problem is not limited to the case where the laying material to be laid on the grass-proof sheet is gravel, but also occurs when sand, wood chips, bark chips, or the like is used as the laying material.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to effectively reuse an empty storage bag after the laying material is taken out, and moreover, to install the laying material on the entire surface of the weed control sheet. An object of the present invention is to provide a bag containing a laying material that can be easily laid in a uniform thickness without excess or deficiency.

The invention according to claim 1 is, in a bag containing a laying material, a storage bag made of a grass-proof sheet laid on the ground and laid on the surface, and the laying material stored in the storage bag. , Is provided.

According to a second aspect of the present invention, in the bag with the laying material according to the first aspect, the storage bag is used as the weed-preventing sheet in a flattened expanded state after the laying material is taken out. , Is characterized.

According to a third aspect of the present invention, in the bag with the laying material according to the second aspect, when the grass-proof sheet in the expanded state is laid evenly without excess or deficiency, the laying material housed in the storage bag is laid, It is characterized in that the laying material has a thickness such that it has a predetermined thickness.

According to a fourth aspect of the present invention, in the bag with the laying material according to any one of the first to third aspects, the spread weed-preventing sheet has a substantially rectangular shape or a substantially square shape. ..

According to a fifth aspect of the present invention, in the bag with the laying material according to the fourth aspect, in the storage bag, the weed-proof sheet having a substantially rectangular shape or a substantially square shape is folded into two in a substantially rectangular shape or a substantially square shape in a developed state. Then, the bag is made by sewing three sides other than the folded portion.

According to the invention of claim 1, the bag containing the laying material comprises a storage bag made of a grass-proof sheet laid on the ground and laid on the surface, and a laying material stored in the storage bag. I have it.

Accordingly, the storage bag can be used as a grass-proof sheet without removing the laying material (for example, gravel, sand, wood chips, and bark chips) and discarding it.

Furthermore, unlike the case where a large amount of laying material is laid on the entire surface of the weed-preventing sheet spread over the construction site to a uniform thickness without excess or deficiency, one weed-preventing sheet is stored in the storage bag. Since the laying material is laid, it is easy to lay it to a uniform thickness without excess or deficiency.

Then, the operation of laying this one grass-proof sheet and laying one bag of laying material on its entire surface to a uniform thickness without excess or deficiency is repeated for a plurality of laying material-containing bags. The material can be laid in a uniform thickness throughout the construction site without excess or deficiency.

According to the second aspect of the invention, the storage bag is used as a weed-preventing sheet in a developed state in which the storage bag is unfolded in a flat state after the laying material is taken out.

As a result, when the storage bag after the laying material is taken out is used as it is as a weed-proof sheet, the weed-proof sheet will be doubled, for example. The area can be secured and used effectively.

According to the third aspect of the invention, the grass-proof sheet in the expanded state has a size such that the laying material stored in the storage bag has a predetermined thickness when the laying material is laid evenly without excess or deficiency. Therefore, the laying material after being laid can not only be laid on the entire surface of the weed-preventing sheet to have a uniform thickness without excess or deficiency, but also to have a predetermined (desired) thickness on the entire surface.

According to the invention of claim 4, the unfolded weed-preventing sheet has a substantially rectangular shape or a substantially square shape. Therefore, it is difficult to form an unnecessary gap between the adjacent weed-preventing sheets.

According to the invention of claim 5, in the storage bag, in the unfolded state, a substantially rectangular or substantially square grass-proof sheet is folded in two into a substantially rectangular shape or a substantially square shape, and the three sides other than the folded portion are sewn together. It is made by bags.

As a result, the next weed-preventing sheet is positioned adjacent to the weed-preventing sheet on which the laying material has been laid in the state of the storage bag before taking out the laying material, and the laying material is sewn without being particularly moved. Can be released (removed) and opened easily.

<Embodiment 1>
The laying material-containing bag 1 according to the first embodiment to which the present invention is applied will be described with reference to FIGS. 1 to 3.

Here, FIG. 1 is an overall perspective view of the bag 1 containing the laying material. 2(A) is a plan view of the unfolded weed-preventing sheet 10, and FIG. 2(B) is a plan view of the weed-preventing sheet 10 folded in two and sewn. 3(A) to 3(H) are diagrams illustrating a method of laying gravel (laying material) S.

The laying material-containing bag 1 includes a storage bag 1A and gravel S as a laying material stored in the storage bag 1A.

Of these, the storage bag 1A is formed by making the weedproof sheet 10.

The weed-proof sheet 10 has a general function as a weed-proof sheet, for example, it prevents the generation of weeds, can easily be pulled out even if the seeds that fly are germinated, pass rain or water, prevent burial of gravel, etc. The material is not particularly limited as long as it satisfies the function of. However, in the present invention, the grass-proof sheet 10 is preferably strong in consideration of bag-making, storing the gravel S and the like, and further carrying it in the stored state. As an example of the grass-proof sheet 10, a material made of polypropylene and having a thickness of about 0.45 mm can be used.

As shown in FIG. 2(A), the grass-proof sheet 10 is formed so that the shape when developed in a planar shape is a substantially rectangular shape or a substantially square shape (for example, a 55 cm square). As shown in FIGS. 2(A) and 2(B), the grass-proof sheet 10 is folded in two at the center C and sewn with threads or strings along the three sides 12, 13 and 14 excluding the folded portion 11. The storage bag 1A is configured by providing the sewn portions 12a, 13a, 14a.

In the actual bag-making work, the grass-proof sheet 10 is folded twice at the center C to form the folded portion 11. Then, stitching is started along the side 14 from the side of the folded portion 11 to form a stitched portion 14a, which is bent near the side 13 into an “L” shape, and the stitched portion 13a is bent along the side 13 as shown in FIG. Form from bottom to top. In this state, the side 12 that will later form the stitched portion 12a can be opened. The storage (filling) of the gravel S is started from this opening, and after the storage of a predetermined amount of the gravel S (for example, about 14 kg) is completed, the stitches 12a are formed by stitching along the side 12. The suture portion 12a is prevented from unraveling by appropriately projecting a thread or a string from both ends.

Here, the grass-proof sheet 10 is set to a size such that the gravel S has a predetermined thickness when the gravel S stored in the storage bag 1A is laid evenly in the expanded state without excess or deficiency. Has been done.

As described above, the storage bag 1A in which the gravel S is stored, that is, the laying material-containing bag 1 can be manufactured.

Next, a method of laying gravel (laying material) S using the above-mentioned bag 1 with laying material will be described with reference to FIGS. 3(A) to 3(H). The grass-proof sheet 10 will be described as having a substantially square shape in the unfolded state.

The laying method of the gravel S stored in the storage bag 1A made by the weedproof sheet 10 is as follows.
(1) Storage bag placing step of placing the storage bag 1A containing the gravel S on the ground G (FIG. 3(A)),
(2) Weed-proof sheet developing step (FIGS. 3B to 3F) in which the storage bag 1A is flatly developed while the gravel S is placed to form the grass-proof sheet 10.
(3) Gravel laying step (FIGS. 3G to 3H) of laying the gravel S with a uniform thickness on the entire surface of the grass-proof sheet 10 in the unfolded state laid on the ground G.
Have.

The details will be described below.

(1)-1
A storage bag 1A (bag 1 with laying material) in which the gravel S is stored is placed on a corner of the ground G at the construction site (FIG. 3(A)).

(2)-1
The side 14 is grasped by one hand HL, and the thread or the string of the suture portion 14a is released (cut) by the cutter Cu held by the other hand (FIG. 3(B)).

(2)-2
The side 14 is opened (FIG. 3(C)).

(2)-3
The side 13 is opened (FIGS. 3D and 3E).

(2)-4
The sewn portion 12a of the side 12 is released (cut), the side 12 is opened, and the grass-proof sheet 10 is developed in a flat shape (FIG. 3(F)).

In addition, in the above-mentioned weed-proof sheet development steps (2)-1 to (2)-4, the gravel S may be left on the weed-proof sheet 10 and need not be actively moved (natural movement). Leave it to).

(3)-1
While putting the gravel leached out from the weed-preventing sheet 10 on the weed-preventing sheet 10, it is evenly distributed on the weed-preventing sheet 10 so that the entire surface is evenly distributed so that the entire thickness is uniform. (FIG. 3(G), (H)).

By the above (1)-1 to (3)-1, the gravel S can be evenly laid on one grass-proof sheet 10 in a developed square shape.

Unlike the case of a large area, the work of laying the gravel S on one grass-proof sheet 10 can lay the gravel S evenly over the entire surface and with the same thickness (depth) relatively easily. ..

When the next bag 1 with laying material is placed on the ground G, the side 13 is placed so as to be adjacent to any one of the four sides of the grass control sheet 10. As a result, when the weed-preventing sheet 10 of the bag 1 containing the laying material is placed in the expanded state later, the weed-preventing sheet 10 is positioned adjacent to the previous weed-preventing sheet 10 with no unnecessary gap. Will be done.

The following (1)-1 to (3)-1 are performed on the bag 1 containing the laying material.

As a result, the gravel S can be laid with a uniform thickness over the entire surface of the two adjacent weed control sheets 10.

The same laying work is repeated for the entire construction site.

As described above, it is possible to relatively easily lay the weed-preventing sheet 10 over the entire construction site, and lay the gravel S on the entire surface of the gravel S in a uniform thickness without excess or deficiency.

In the above, the case where the shape of the grass-proof sheet 10 in the expanded state is a substantially square shape has been described as an example, but the shape is not necessarily limited to this. For example, it may have a substantially rectangular shape.

As described above, by using the grass-proof sheet 10 having a substantially square shape or a substantially rectangular shape in the unfolded state, it is possible to easily form an unnecessary gap between two adjacent grass-proof sheets 10. Can be prevented.

In addition, when the weed-preventing sheet 10 in a developed state has a substantially square shape, unlike the case where the weed-proof sheet 10 has a substantially rectangular shape, the following weed-controlling agent is applied to any one of the four sides of the previous weed-controlling sheet 10. Since the sheets 10 can be adjacent to each other, workability is improved accordingly. That is, the grass-proof sheet 10 preferably has a substantially rectangular shape or a substantially square shape in the unfolded state, and further preferably has a substantially square shape.

Although the case where the laying material is the gravel S has been described above, sand, wood chips, bark chips, and the like can be used as the laying material.

Further, in the above description, the case where the storage bag 1A is formed by sewing the grass-proof sheet 10 with a thread or a string has been described as an example, but instead of this, an adhesive may be used, or heat fusion bonding may be performed. It is also possible to make a bag by using. In these cases, for example, the storage bag can be developed on the grass-proof sheet by cutting with a cutter or the like.

Moreover, although the case where the shape of the weed-preventing sheet 10 before bag making and the shape of the weed-preventing sheet 10 after development are the same has been described above as an example, they do not necessarily have to be the same.

Hereinafter, the operation and effect of the above-mentioned laying material-containing bag 1 will be summarized.

The bag 1 containing the laying material includes the storage bag 1A formed by the weed-proof sheet 10 laid on the ground G and laid with the gravel (laying material) S on the surface, and the gravel S stored in the storage bag 1A. Since the storage bag is provided with the gravel S, the storage bag can be used as the weed-preventing sheet 10 without discarding it.

Further, unlike the case where a large amount of gravel S is laid on the entire surface of the weed-preventing sheet 10 spread at the construction site to have a uniform thickness without excess or deficiency, one weed-preventing sheet 10 is stored in the storage bag 1A. Since the existing gravel S is laid, it is easy to lay it to a uniform thickness without excess or deficiency.

By laying this one grass-proof sheet 10 and laying one bag of gravel S on its entire surface to a uniform thickness without excess or deficiency, by repeating this for a plurality of laying material-containing bags 1. The gravel S can be laid in a uniform thickness throughout the construction site without excess or deficiency.

-Since the storage bag 1A is used as the weed-preventing sheet 10 in a flattened expanded state after the gravel S is taken out, the storage bag 1A after taking out the gravel S is used as it is as the weed-proof sheet 10. When it is used, the weed-preventing sheet will be doubled, for example, but by using it in an unfolded state, it is possible to secure an approximately double area and effectively use it.

The laid grass grass sheet 10 has a size such that the gravel S has a predetermined thickness when the gravel S stored in the storage bag 1A is evenly laid without excess or deficiency. The later gravel S is not only laid on the entire surface of the weed-preventing sheet 10 with a uniform thickness, but also can have a predetermined (desired) thickness on the entire surface.

Since the weed-preventing sheet 10 in the developed state has a substantially rectangular shape or a substantially square shape, it is difficult for an unnecessary gap to be formed between the adjacent weed-control sheets.

The storage bag 1A is manufactured by folding an approximately rectangular or approximately square grass-proof sheet into two approximately rectangular or approximately square shapes in the unfolded state, and stitching the three sides other than the folded portion.

As a result, the next weed-preventing sheet 10 is positioned adjacent to the weed-preventing sheet 10 on which the gravel S has been laid in the state of the storage bag 1A before taking out the gravel S, and the gravel S is particularly moved. The suture can be released (removed) without any need for easy opening.

The laying method of the gravel S is as follows: a storage bag placing step of placing the storage bag 1A containing the gravel S on the ground, and expanding the storage bag 1A in a flat state with the gravel S placed on the ground as the grass control sheet 10. The method includes a weed-proof sheet developing step of laying on G and a laying material laying step of laying gravel S with a uniform thickness on the entire surface of the spread grass-proof sheet 10 laid on the ground G.

Thus, one bag of gravel S can be easily laid in a uniform thickness over the entire surface of the grass-proof sheet 10 in the expanded state for one bag.
