Description

TECHNICAL FIELD The present invention relates to a sheet for a simple container, a simple container set, and a simple container that are used for portable toilets, portable containers, and the like.

Toilets are a serious problem when disasters such as earthquakes occur. In preparation for the occurrence of disasters such as earthquakes, evacuation centers and support stations for people unable to return home have been established in various places. However, the number of existing toilets at evacuation centers is absolutely insufficient for the number of victims expected in a large-scale disaster. It may take several weeks. Moreover, even at home or in public places, the flush toilet cannot be used due to reasons such as power failure, water outage, damage to water supply and drainage pipes, and the like. For this reason, it is desired to stockpile and carry portable toilets so that people can excrete in places without toilets.

As such a portable toilet, there are those described in Patent Document 1 and Patent Document 2, for example. The portable toilet described in Patent Literature 1 has a special shape for the opening of the bag and a guide wall for excrement inside the bag. In the portable toilet described in Patent Document 2, a foldable frame body is spread out, four corners of the bottom of the frame body are held and reinforced by reinforcing members, a bag is put on the frame body, and the bag is secured to the frame body by a fixing member. is fixed to

However, the portable toilet described in Patent Literature 1 does not stand on its own and is intended to be held by hand. Therefore, it is difficult to use when excreting, and women in particular hesitate to use it. In this regard, the portable toilet described in Patent Document 2 can solve this problem because it stands on its own. However, since the number of parts is large and the reinforcing members and fixing members are bulky, there are problems of poor portability and poor assembly. Similar problems arise when these portable toilets are used as simple containers for storing things.

An object of the present invention is to provide a sheet for a simple container, a simple container set, and a simple container that have good portability and can be easily assembled.

A sheet for a simple container according to the present invention is a sheet for a simple container that is used as a simple container together with a bag having an opening, and is formed with a pair of mutually spaced cut lines that do not reach the periphery of the sheet for a simple container. .

In this sheet for a simple container, a pair of cut lines are formed that are spaced apart from each other and do not reach the periphery of the sheet for a simple container. For this reason, the sheet for a simple container is folded so that the pair of cut lines form a U shape, and the opening of the bag is opened so that the part sandwiched by the pair of cut lines is inside the bag. can be inserted into the cut line of

When the opening of the bag is inserted into the pair of cut lines in this manner, the bag is sandwiched between the pair of cut lines and held in a state of being inserted between the pair of cut lines. Here, the sheet for a simple container, which is bent so that the pair of cut lines are U-shaped, tends to open so that both side surfaces are separated from each other, or close so that both side surfaces approach each other. However, the bag forms the sides of the simple container together with the sheet for the simple container by being inserted into the pair of cut lines. As a result, both side surfaces of the sheet for a simple container are supported by the bag, thereby suppressing opening and closing of the sheet. Furthermore, the outer portions of the pair of cut lines are arranged outside the bag, and these outer portions function as appropriate springs or weights and support both sides of the simple container sheet from the outside of the bag. , both sides of the sheet for a simple container are suppressed from being closed or opened. This makes it possible to create a self-supporting simple container. Therefore, for example, when this simple container is used as a portable toilet, it is easier to use when excreting than a container that does not stand on its own, and women are less hesitant to use it.

Further, when the opening of the bag is inserted into the pair of cut lines, the outer portion of the pair of cut lines of the simple container sheet protrudes from the bag. can be covered with Therefore, for example, when this simple container is used as a portable toilet, it is possible to alleviate the discomfort caused by the feet touching the opening of the bag.

Further, when the simple container is used, the contents of the simple container can be sealed in the bag by putting the simple container sheet into the bag and closing the bag. Therefore, for example, even if the content of the simple container is excrement or the like with a strong odor, it is possible to prevent the odor from leaking out.

Moreover, a simple container can be produced if at least the sheet for the simple container and the bag are provided. Moreover, the sheet for a simple container can be folded and does not become bulky even when folded. Therefore, the portability is extremely good.

In the sheet for a simple container described above, the pair of cut lines may be formed parallel to each other. In this simple container sheet, since the pair of cut lines are formed parallel to each other, the pair of cut lines can be easily folded into a U-shape. Moreover, when the opening of the bag is inserted into the pair of cut lines, the inner shape of the simple container can be made rectangular. Therefore, compared to the case where the pair of cut lines are not formed parallel to each other, it is possible to easily assemble and use the simple container efficiently.

[Simple container set]
A simple container set is a set for creating the simple container 1 . The simple container set includes the simple container sheet 2 described above and the bag 4 described above. As the simple container sheet 2 included in the simple container set, for example, the folded simple container sheet 2 shown in FIG. 7 or 8 is used. Moreover, when the simple container 1 is used as a simple toilet, it is preferable that the simple container set further includes a coagulant, a deodorant, and the like. Moreover, it is preferable to use the sheet|seat 2 for simple containers as the sheet|seat 2 provided with the deodorizing function. The simple container set is collectively housed in one bag or the like.

[How to create a simple container]
Next, an example of a method for creating the simple container 1 using the simple container set will be described.

First, as shown in FIG. 12, the folded simple container sheet 2 shown in FIG. 7 or FIG. When the sheet 2 for a simple container put in the bag 4 is folded as shown in FIG. 8, the sheet 2 for a simple container is folded inside the bag 4 as shown in FIG.

Next, as shown in FIG. 13, the folded simple container sheet 2 is opened and the bag 4 is expanded to form the support 3. Next, as shown in FIG.

Next, as shown in FIG. 14, the first outer portion 25a and the second outer portion 25b are pulled out from the bag 4, and the opening 41 of the bag 4 is inserted into the first cut line 11a and the second cut line 11b. . Then, the bag 4 is pulled up to the upper end or the vicinity of the upper end of the first cut line 11a and the second cut line 11b. Also, the first end portion 23 a and the second end portion 23 b are pulled out of the bag 4 and covered over the opening 41 of the bag 4 . In addition, when the bag 4 is too large with respect to the support 3 and the opening 41 of the bag 4 is doubled, the doubled portions are divided into the first end portion 23a and the second end portion 23b and the first inner side surface portion. 24a and the second inner side surface 24b.

When the bag 4 is inserted into the first cut line 11a and the second cut line 11b in this manner, the bag 4 is sandwiched between the inner portion 24 and the first outer portion 25a and the second outer portion 25b, thereby It is held in a state of being inserted into the first cut line 11a and the second cut line 11b.

Here, the support 3 (the sheet for a simple container 2), which is bent so that the first cut line 11a and the second cut line 11b are in a U shape, has a first inner side surface portion 24a and a second inner side surface portion 24a. Portions 24b try to open away from each other, and first and second inner side portions 24a and 24a try to close toward each other. However, the bag 4 forms the side surface of the simple container 1 together with the first inner side surface portion 24a and the second inner side surface portion 24b by being inserted into the first cut line 11a and the second cut line 11b. As a result, the first inner side surface portion 24a and the second inner side surface portion 24b are supported by the bag 4, and are prevented from opening and closing. Furthermore, the first outer side portion 25a and the second outer side portion 25b that are exposed to the outside of the bag 4 serve as appropriate springs or weights, and the first inner side portion 24a and the second inner side portion 24b extend from the outside of the bag 4. support the top edge of the This suppresses the opening and closing of the first inner side surface portion 24a and the second inner side surface portion 24b.

The production of the simple container 1 is completed as described above. As shown in FIGS. 1 to 5, 9 and 14, in the simple container 1, the support 3 is formed so that the first cut line 11a and the second cut line 11b are U-shaped. It is folded at the folding line 33a for the second bottom side and the folding line 33b for the second bottom side. Also, the bag 4 is inserted into the first cut line 11a and the second cut line 11b so that the inner portion 24 enters the bag 4 and the first outer portion 25a and the second outer portion 25b exit the bag 4. there is The support 3 is folded along the first upper fold line 32a and the second upper fold line 32b, and the first end 23a and the second end 23b cover the opening 41 of the bag 4. .

As described above, in the present embodiment, the first cut line 11a and the second cut line 11b that do not reach the periphery of the simple container sheet 2 and are spaced apart from each other are formed. For this reason, the simple container sheet 2 is folded so that the first cut line 11a and the second cut line 11b form a U-shape, and the sheet is sandwiched between the first cut line 11a and the second cut line 11b. The opening 41 of the bag 4 can be inserted through the first score line 11a and the second score line 11b so that the folded inner portion 24 is inside the bag 4 . By inserting the opening 41 of the bag 4 into the first cut line 11a and the second cut line 11b, the self-supporting simple container 1 can be produced. Therefore, for example, when this simple container 1 is used as a simple toilet, it is easier to use when excreting than a container that does not stand on its own, and women are less hesitant to use it.

Further, when the opening 41 of the bag 4 is inserted into the first cut line 11a and the second cut line 11b, the first outer side portion 25a and the second outer side portion 25b of the sheet for simple container 2 protrude from the bag 4. However, the first outer portion 25a and the second outer portion 25b can be folded to cover the opening 41 of the bag 4. As shown in FIG. Therefore, for example, when this simple container 1 is used as a portable toilet, the discomfort caused by the foot touching the opening 41 of the bag 4 can be alleviated.

When the simple container 1 is used, the support 3 made of the simple container sheet 2 is put into the bag and the bag is closed, so that the contents of the simple container 1 can be sealed in the bag. Therefore, for example, even if the contents of the simple container 1 contain excrement or the like with a strong odor, it is possible to prevent the odor from leaking out. In addition, when the simple container 1 is a portable toilet, by adding a coagulant and a deodorant before or after use, it is possible to coagulate moisture such as urine and further suppress leakage of odors. can do.

Moreover, the simple container 1 can be produced if at least the simple container sheet 2 and the bag 4 are provided. The simple container sheet 2 can be folded and does not become bulky even when folded. Therefore, the portability is extremely good.

In addition, since the first cut line 11a and the second cut line 11b are formed parallel to each other, the simple container sheet is cut so that the first cut line 11a and the second cut line 11b are U-shaped. It becomes easier to fold 2. Further, when the opening 41 of the bag 4 is inserted into the first cut line 11a and the second cut line 11b, the inner shape of the simple container 1 can be made rectangular. Therefore, compared to the case where the first cut line 11a and the second cut line 11b are not formed parallel to each other, the simple container 1 can be easily assembled and used efficiently.

Further, since the first cut line 11a and the second cut line 11b are formed in parallel with the sides 21a and 21b of the rectangular simple container sheet 2, the simple container 1 can be formed into a substantially rectangular box shape. can be formed. Thereby, the usability of the simple container 1 can be improved.

Further, when the simple container sheet 2 is folded at the first bottom fold line 33a and the second bottom fold line 33b, the simple container sheet 2 can be opened to easily fold the first fold line 11a. And the sheet for simple containers 2 can be folded so that the second cut line 11b has a U-shape. Further, the first cut line 11a and the second cut line 11b are perpendicular to the first bottom fold line 33a and the second bottom fold line 33b, so that the simple container 1 is shaped like a substantially rectangular parallelepiped box. can be formed.

Further, when the sheet for simple container 2 is folded at the fold line 34 opposite to the first bottom fold line 33a and the second bottom fold line 33b, the sheet for simple container 2 has a bellows shape. It is in a folded state. This further reduces the size of the simple container sheet 2, thereby further improving portability. Moreover, by opening the sheet 2 for a simple container, the first cut line 11a and the second cut line 11b can be easily formed into a U-shape.

In addition, when the sheet for a simple container 2 is folded back at the first top fold line 32a and the second top fold line 32b opposite to the first bottom fold line 33a and the second bottom fold line 33b. can easily cover the opening 41 of the bag 4 with the first end 23a and the second end 23b protruding from the bag 4 when the simple container 1 is produced.

In addition, since both ends of the first cut line 11a and the second cut line 11b are positioned on the first upper fold line 32a and the second upper fold line 32b, when creating the simple container 1, By inserting the opening 41 of the bag 4 into the first cut line 11a and the second cut line 11b, the bag 4 can be raised to the upper end of the simple container 1 or near the upper end. Thereby, the capacity of the simple container 1 can be improved.

In addition, when each of the first cut line 11a and the second cut line 11b is a perforation line cut intermittently, when carrying, the first cut line 11a and the second cut line 11b are easy to carry. It is possible to suppress the breakage of the sheet for a simple container 2 with this as a base point. In addition, when creating the simple container 1, the opening 41 of the bag 4 is cut along the first cut line 11a and the second cut line 11b by breaking the perforations along the first cut line 11a and the second cut line 11b. It can be inserted into the cut line 11b.

In addition, when the circumference of the opening 41 of the bag 4 is in the range of 90% to 130%, 95% to 125%, or 100% to 120% of the circumference of the inner bottom portion 24c, , When the opening 41 of the bag 4 is inserted into the first cut line 11a and the second cut line 11b, the opening 41 of the bag 4 is prevented from becoming squished, thereby improving the shape retainability of the simple container 1. be able to.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments.

Since the simple container sheet can be folded (folded back) without ruled lines, the ruled lines described above are not necessarily required, and some or all of the ruled lines may be omitted.

For example, as in the sheet for simple containers 2A shown in FIG. 15(a), all the ruled lines may not be formed. In this case, by folding the sheet 2A for a simple container, it can be folded back at each of the folding lines.

Similarly, like the sheet 2B for a simple container shown in FIG. And the second upper side ruled line 12b may not be formed. In this case, by folding along the first bottom ruled line 13a, the second bottom ruled line 13b, and the folding ruled line 14, and folding at positions corresponding to the first upper ruled line 12a and the second upper ruled line 12b, each of the above-mentioned It can be folded at the crease line.

Similarly, like the sheet 2C for a simple container shown in FIG. , and the folding ruled lines 14 may not be formed. In this case, by folding at the first bottom ruled line 13a, the second bottom ruled line 13b, the first upper ruled line 12a, and the second upper ruled line 12b, and by folding at the position corresponding to the folding ruled line 14, each of the above It can be folded at the crease line.

Moreover, in the sheet for a simple container in a folded state, each folding line described above is not necessarily required, and any part or all of them may be omitted. In this case, when creating the simple container, for example, by folding at positions corresponding to the first bottom ruled line 13a, the second bottom ruled line 13b, the first top ruled line 12a, and the second top ruled line 12b, the container can be supported. can be a body.

Further, the simple container sheet may have no crease lines or crease lines for folding, or may have two or more crease lines. When there are two or more folding ruled lines or folding crease lines, the position of each line can be set as appropriate according to storage, portability, and the like.

Also, the position, length, direction, etc. of the pair of cut lines can be changed as appropriate. For example, as in a sheet 2D for a simple container shown in FIG. 16(a), both ends of the first cut line 11a and the second cut line 11b are formed by the first upper edge ruled line 12a (first upper edge crease line 32a). and the second upper-side ruled line 12b (the second upper-side fold line 32b), and may be positioned inside the first upper-side ruled line 12a and the second upper-side ruled line 12b. Similarly, like the sheet 2F for a simple container shown in FIG. direction).

Moreover, the sheet-like member forming the sheet for a simple container does not necessarily have to be rectangular, and can have various shapes. For example, a sheet 2E for a simple container shown in FIG. 16(b) may have a shape in which a pair of opposing sides are curved, and a sheet 2F for a simple container shown in FIG. 16(c) may have a trapezoidal shape. may be

17 to 20 show a modified simple container sheet 2G. The simple container sheet 2G shown in FIGS. 17 to 20 is basically the same as the simple container sheet 2 of the above-described embodiment, but does not have the first upper edge ruled line 12a and the second upper edge ruled line 12b. In addition, the simple container sheet 2 of the above embodiment only has the same interval between the side 22a, the first bottom ruled line 13a, the second bottom ruled line 13b, the folding ruled line 14, and the side 22b in the unfolded state. differ from Since the sheet 2G for a simple container does not have the first upper edge ruled line 12a and the second upper edge ruled line 12b, the first end portion 23a is located on the side 22a side of the first cut line 11a and the second cut line 11b. The second end portion 23b is a portion from the tip of the first cut line 11a and the second cut line 11b on the side 22b side to the side 22b.

The simple container sheet 2G in the unfolded state shown in FIG. 17 is folded into valley folds along the first bottom ruled line 13a and the second bottom ruled line 13b to form the first bottom fold line 33a and the second bottom fold line 33b, Folding along the folding lines 14 to form the folding lines 34 results in the folded state shown in FIG. 18, and further folding along the folding lines 15 results in the folded state shown in FIG. . Since the side 22a, the first bottom ruled line 13a, the folding ruled line 14, the second bottom ruled line 13b, and the side 22b are equidistant, they can be easily developed as shown in FIG. 17 by a machine such as a paper folding machine. The simple container sheet 2G in this state can be folded into the folded state shown in FIG. Therefore, it is possible to reduce the manufacturing cost for folding the simple container sheet 2G in the unfolded state shown in FIG. 17 to the folded state shown in FIG.
