DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shape-retaining box for a bag, which is used together with a commercially available garbage collection bag called a plastic bag and assembles the garbage collection bag into a simple trash box or the like. It is.

[0002]

[Prior Art] In parks and tourist spots where many people gather,
From the beginning, round and square metal trash cans are permanently installed, and trash can be easily thrown into these trash cans.

[0003]

However, in a case where a sports day is held on a school ground or a temporary event is held in a temporary venue, when a large number of people gather,
Since there are no permanent trash cans in these places, you will be in trouble for dumping garbage.

In such a place, it is conceivable to collect garbage using a commercially available garbage collection bag.
If the commercially available garbage collection bag is used as it is, each time the flexible garbage collection bag must be opened and the garbage must be discarded, it is extremely disadvantageous in use. The same can be said for a case where a garbage collection bag is used for collecting fallen leaves in garden cleaning or the like.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been developed in view of the above circumstances, and the invention according to claim 1 is at least a paper polygon having a planar polygonal shape accommodated in a flexible bag. And a structure in which the edge of the flexible bag can be temporarily fixed to the tubular body side.

According to a second aspect of the present invention, there is provided a paper cylindrical main body having a planar polygonal shape accommodated in a flexible bag.
A guide flange made of paper, which has a planar polygonal shape similar to the cylindrical main body and is fixed to an upper end opening of the cylindrical main body,
Forming a plurality of insertion grooves in one of the side wall piece defining the polygonal shape of the cylindrical body or the side wall piece defining the polygonal shape of the guide flange body, forming a plurality of connecting pieces on the other, By inserting the respective connecting pieces into the corresponding insertion grooves, the polygonal shape of the tubular body can be maintained, the guide flange can be fixed to the upper end opening of the tubular body, and the opening of the flexible bag can be opened. The structure which can temporarily fix an edge to a cylindrical main body side was adopted.

According to the third aspect of the present invention, based on the premise of the second aspect, a configuration is adopted in which the upper side of the guide flange is expanded obliquely upward.

According to a fourth aspect of the present invention, based on the second and third aspects, the cylindrical main body and the guide flange have a planar hexagonal shape, and the hexagonal shape of the cylindrical main body and the guide flange is defined. A configuration is adopted in which each side wall piece to be connected is sequentially connected via a folding line.

Therefore, according to the first aspect of the present invention, if this simple box is used together with a commercially available garbage collection bag to assemble a simple garbage box, a flat garbage can be placed inside the garbage collection bag. By storing the polygonal tubular body and temporarily fixing the rim of the garbage collection bag to the tubular body side,
At the same time as the garbage collection bag is kept in a shape conforming to the polygonal shape of the cylindrical main body, the simple trash can is immediately assembled.

According to the second aspect of the present invention, the state where the connecting piece is inserted into the insertion groove is obtained, and the guide flange body also presenting the planar polygonal shape is stopped at the upper end opening of the cylindrical body exhibiting the planar polygonal shape. After the wearing, the main shape box is turned upside down and the garbage collection bag is put on the cylindrical main body from above, so that the cylindrical main body can be easily stored inside the garbage collection bag.

Therefore, after that, the box is returned to a normal position, and the rim of the garbage collection bag is temporarily fixed to the cylindrical main body side. At the same time, the simple trash can is assembled immediately.

According to the third aspect of the present invention, it is possible to use the guide flange body whose upper side is opened obliquely upward as a guide to put refuse in the refuse collection bag held by the cylindrical main body. According to the invention of claim 4, the cylindrical main body including the guide flange body is made as close as possible to a perfect circle in the use state as a trash can, and the cylindrical main body and the guide flange are used in the unused state. The advantage is that the body can be folded very compactly.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to a preferred embodiment, in which a bag-shaping box according to the embodiment is provided inside a flexible bag as described above. It comprises a tubular main body 1 to be housed, and a guide flange 11 fixed to the upper end opening of the cylindrical main body 1. Both the tubular main body 1 and the guide flange 11 are made of corrugated cardboard. Made of cardboard.

More specifically, first, as shown in FIG. 1, the former cylindrical main body 1 has six side wall pieces 2 connected in a horizontally long manner through individual folding lines a, and one end thereof has one end. The narrow side wall piece 2 is also provided with one narrow glue margin piece 3 which is also connected via the fold line a, and the insertion groove 4 is formed in the upper part of every other one of the six side wall pieces 2. At the same time, a folded piece 5 is cut out and formed at the upper part of the one side wall piece 2 where the insertion groove 4 is not formed, and the folded piece 5 is folded inward, so that the upper part of the tubular main body 1 is gripped. It is configured so that a signature 6 can be opened. Each of the side wall pieces 2 is set in a rectangular shape having an equal width dimension, and each inner surface is subjected to a water-repellent treatment.

Therefore, if the adhesive margin piece 3 is adhered to the inside of the end edge of the side wall piece 2 located at the other end via an adhesive or the like, FIG.
As shown in A, when the upper and lower ends are opened, the tubular main body 1 can be developed into a use state of exhibiting a planar hexagonal shape through each fold line a. From the state, an arbitrary fold line a is selected, and two adjacent side wall pieces 2 are bent inward across the fold line a. Then, as shown in FIG. 2B, the cylindrical main body 1 is flattened. It can be folded into a non-use state that assumes a shape. In addition, in this folded state, since it can be folded to the size of the two side wall pieces 2, it becomes extremely compact, which is extremely convenient for packaging and handling.

As shown in FIG. 3, the latter guide flange body 11 has six side wall pieces 12 connected in an arc shape through individual folding lines b and opposite side wall pieces 12 located at both ends. And two locking pieces 13 connected to each other, and a lock piece 14 having substantially the same size as the side wall piece 2 of the tubular main body 1 is provided at a lower portion of every other one of the six side wall pieces 12. In addition to the connection via the fold line c, the connection piece 15 inserted into the insertion groove 4 is connected to the lock piece 14 via the fold line d. Each of the side wall pieces 12 is
It is set to an inverted trapezoidal shape with the same width, and the inner surface is also water-repellent.

In addition, for each connecting piece 15,
As shown in the figure, a fixing hole 16 with a score line 17 that can be temporarily fixed by pushing the edge of a flexible bag is formed, and a lock piece 14 is formed.
For the remaining three side wall pieces 12 that are not connected,
The lower portion is slightly extended without interfering with the adjacent lock piece 14, and each extension 18 is arranged along the edge of the upper end opening of the corresponding side wall piece 2 of the tubular main body 1.

Therefore, the two locking pieces 1 at both ends are provided.
3 are locked together, as shown in FIG.
2. Due to the inverted trapezoidal shape of 2, the upper side of the guide flange body 11 obtains a state in which the upper side expands obliquely upward, and the guide flange body 11 can be developed to a use state exhibiting a planar hexagonal shape through each fold line b. Conversely, when the side wall piece 12 is folded in two steps from each of the deployed use states by appropriately using the respective folding lines b, as shown in FIG. 4B, the guide flange body 11 also has a flat shape. It can be folded extremely compactly in the non-use state presented. In addition, regarding the folding of the guide flange body 11,
If it is folded in three steps, it will be somewhat bulky, but as a whole it will be more compactly foldable.

Therefore, it is now assumed that the shape retaining box according to the present embodiment is used together with a commercially available flexible garbage collection bag,
When assembling a simple trash can, the lock piece 14 and the connecting piece 15 of the guide flange body 11 which is also hexagonally expanded are provided inside the upper end opening of the cylindrical main body 1 which is expanded hexagonally.
When the three connecting pieces 15 are bent from the inside into the corresponding insertion grooves 4 of the cylindrical body 1 while bending the three connecting pieces 15 through the fold line d, as shown in FIG. 11 can be easily fixed to the upper end opening side of the tubular main body 1.

In addition, in the fixed state of the guide flange body 11, as shown in FIG. 6A, the lock pieces 14 connected with the connection pieces 15 are every other one, but the folding line c , And overlaps the inner surface of the corresponding side wall piece 2 of the cylindrical main body 1, so that both side edges thereof abut against the adjacent side wall piece 2, whereby the hexagonal shape of the cylindrical main body 1 is ensured. , And there is no fear that the tubular body 1 in the deployed state is inadvertently deformed or crushed. Lock piece 1
The extension 18 of the side wall piece 12 not connected to the side 4 is shown in FIG.
As shown in FIG. 2B, since the protrusion protrudes inward through the upper edge of the corresponding side wall piece 2 of the cylindrical main body 1, an unnecessary gap is formed between the guide flange body 11 and the cylindrical main body 1 in any case. It does not occur.

Then, as shown in FIG. 7, the garbage collection bag B is put on the cylindrical main body 1 from above with the shape-retaining box turned upside down, and the cylindrical main body 1 is placed inside the garbage collection bag B. Since the storage box can be easily stored, the shape-retaining box is returned to a normal position, and the rim Ba of the garbage collection bag B is rounded and temporarily fixed in the fixing hole 16 of each connecting piece 15, as shown in FIG. At the same time, the garbage collection bag B is kept in a shape conforming to the hexagonal shape of the cylindrical main body 1, and the simple trash can is immediately assembled. Therefore, under such an assembled state, dust can be put into the dust collection bag B held by the tubular main body 1 by using the guide flange 11 whose upper side expands obliquely upward. Therefore, when used, there is no difference from a trash can that is permanently installed in a park or the like.

However, since the simple trash can according to the present embodiment is lightweight and portable, it is very effective for a school ground where no trash can is permanently installed, a temporary event hall, a campsite, and the like. -It goes without saying that it is practical, but it is extremely convenient to use when picking up fallen leaves in order to clean the garden.
When the simple trash can is moved, it is only necessary to turn the folded piece 5 inward and put a finger into the handle opening 6 of the tubular main body 1 as described above.

When the garbage collection bag B held by the cylindrical main body 1 is full of garbage, the garbage collection bag B is temporarily fixed to the fixing hole 16 at the rim Ba, and By pulling out the storage box itself from the garbage collection bag B, the storage box can be reused and the trash can be discarded together with the trash collection bag B, which is extremely rational.

In the case where the shape retaining box itself is damaged and cannot be reused due to damage, the guide flange 11 is disassembled from the tubular main body 1 and put in the garbage collection bag B.
The shape box itself can be discarded together with the garbage. Moreover,
Since both the guide flange body 11 and the cylindrical main body 1 are made of cardboard discarded as burning dust, there is no problem in disposal.

In the above-described embodiment, the insertion groove 4 is formed on the cylindrical main body 1 side, and the connecting piece 15 is formed on the guide flange body 11 side. However, the present invention is not limited to this.
It is also optional to form the insertion groove 4 on the guide flange 11 side according to the implementation. In this case, a connecting piece 15 is formed on each side wall piece 2 of the cylindrical main body 1 in the same manner as the folded piece 5, and a notch or the like for temporarily fixing the edge Ba of the garbage collection bag B to the cutout edge thereof. And the lock piece 14 of the guide flange 11
Is extended to form the insertion groove 4 in the lock piece 14.

Further, in the embodiment, the tubular main body 1 and the guide flange 11 are formed in a planar hexagonal shape, but this is not limited to this, and the same principle is applied. On the basis of this, it is sufficiently possible to form a polygonal shape other than a hexagonal shape, but in particular, when a hexagonal shape is used, as described above, the tubular main body 1 can be moved as much as possible in the state of use as a trash can. In a non-use state, there is an advantage that the cylindrical main body 1 and the guide flange body 11 can be compactly folded while being substantially close to a perfect circular shape.

Further, the shape-retaining box of the present invention is not intended only for a commercially available garbage collection bag, but is also applicable to a case where sand, gravel or mud is packed in a hemp bag or the like as described above. If the tubular main body 1 of the shape-retaining box is stored inside a hemp bag or the like, sand or the like can be easily stuffed from the guide flange body 11 while the hemp bag is kept in a temporary fixed shape. The range of use is very large.

[0028]

As described above, according to the present invention, by adopting the above-described structure, a flexible bag can be shaped into a polygonal shape conforming to a cylindrical main body, and dust can be put inside the bag, sand or the like can be removed. Because it can be packed, there is a great advantage that when used together with a bag, a simple trash can can be provided immediately, and the shape retention box itself is lightweight and highly portable, so it can be used anywhere. Become.

In addition, according to the third aspect of the present invention, it is possible to put dirt, sand, and the like in the bag held by the cylindrical main body by using the guide flange body whose upper side expands obliquely upward. According to the fourth aspect, in the use state, the cylindrical main body including the guide flange body is made as close as possible to a perfect circular shape, and in the non-use state, the cylindrical main body and the guide flange body are made extremely compact. It can be folded.
