Description

  The present invention relates to an assembly box made of corrugated cardboard or cardboard that can be dissolved.

Documents such as important documents and confidential documents that are no longer needed at the office are collected, and it takes time to cut a large number of documents with a shredder when disposing of them. More and more places are outsourced to specialized processors.
As a collection tool for such specialized processing contractors to collect discarded documents, a collection box formed by providing a document loading port on the upper surface and an opening / closing door on the front surface, and a collection bag made of cloth or opaque synthetic resin material If the collection bag is stored in the collection box, the document is put in the collection box, and the waste document is filled in the collection box, the collection bag is taken out from the collection box and the upper opening of the bag is closed with a string. There is known a method in which this is dissolved as it is so that the discarded document can be effectively recycled (see, for example, Patent Document 1).

Utility Model Registration No. 3046208

If you put waste documents in a collection bag made of cloth or synthetic resin material, even if you stack the stacked documents and put them in the collection bag, the collection bag is indefinite and difficult to carry by hand. It is inconvenient to transport because it cannot be stacked exactly on the loading platform. There is also a risk that the collection bag may be torn during transportation.
Therefore, instead of such a collection bag, it is conceivable to use a paper box that is easy to carry and can be dissolved, but a box having a structure suitable for storing discarded documents is not used. Is real.
That is, in such a box, first of all, it must be folded and stored in a flat shape before use, and can be transported. Second, it is difficult to be deformed in the assembled state. It is necessary that there is no gap through which the inside document can come out when it is stored and the lid is closed, and the document cannot be taken out from the outside of the box.
However, currently used paper boxes have low strength when assembled even when folded, and there is a gap between the side plate and the bottom plate or lid plate with the lid closed. . In order to increase the strength when assembled, forming the box with thick and rigid paper would increase the manufacturing cost and sealing tape along the periphery of the box to close the gap If it is pasted, it will take time to prepare for the collection of discarded documents.

  Therefore, in view of such problems of the prior art, the present invention folds a paper assembly box into a flat shape before use and has a high strength in the assembled state, and is sealed without creating a gap in the closed state. An object of the present invention is to make it possible to use it for storing discarded documents instead of a collection bag when discarding confidential documents.

  In order to solve the above problems, the paper assembly box of the present invention is formed by bending a single punched board made of thick paper such as cardboard, and the punched board is on the left and right sides of the long side walls that are the front and rear of the box. A short side wall is connected via a vertical folding line, a margin is provided at the end of the side wall via a vertical folding line, and the width of the short side wall is substantially equal to the upper edge of the long side wall via a horizontal folding line. A rectangular inner flap that protrudes with the same dimensions, and a rectangular bottom flap that protrudes with the same dimension as the width of the short side wall are connected to the lower edge via a horizontal folding line. A vertical fold line provided with a notch cut obliquely from the base connected to the fold line, with a notch extending laterally along the end of the notch and extending to the lower edge crossing the end of the notch The upper edge of the long side wall on the other side is approximately the same as the width of the short side wall via a horizontal folding line. A square-shaped top lid flap that protrudes and a trapezoidal bottom flap that protrudes approximately half the width of the short side wall through the horizontal folding line are connected to the lower edge, and the upper edge of both short side walls is connected to the horizontal folding line. The inner overlapping wall protrudes with approximately the same dimension as the height of each side wall, and a substantially trapezoidal bottom flap that protrudes approximately half the width of the short side wall is connected to the lower edge via a horizontal folding line. A support piece is provided at the top of the overlap wall via a horizontal folding line, and a diagonal folding line starting from a corner connected to the horizontal folding line is provided on the bottom flap, and a triangular paste margin is provided outside the diagonal folding line. An insertion piece is provided through a fold line around the upper lid flap provided continuously with the long side wall on the other side, and a slit for engaging the insertion piece is formed on a horizontal fold line on the upper edge of the short side wall. It has the structure formed by each, It is characterized by the above-mentioned.

A preferred embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a development view of a punched substrate constituting an assembly box according to the present invention, and this figure shows a surface which is the outside of the box.

  This punching substrate is formed by punching cardboard or other cardboard that can be melted, and the long side walls 1 and 2 that are the front and rear of the box and the short side walls 3 and 4 that are the left and right sides are vertically folded lines 5, 6, 7. Are provided on the end of the long side wall 2 via a vertical folding line 8, and a flap serving as a lid and bottom of the box via horizontal folding lines 10, 11 at the upper and lower edges of each long and short side wall. Are connected to each other.

More specifically, the upper edge of the long side wall 1 has a rectangular inner lid flap 12 projecting with a width approximately equal to the width of the short side walls 3 and 4 (reference numeral D in the figure) via the horizontal folding line 10, and the lower edge has Square-shaped bottom flaps 13 projecting with substantially the same dimensions as the widths of the short side walls 3 and 4 via the horizontal folding line 11 are connected to each other.
The bottom flap 13 is provided with a notch 13a obliquely cut from the base connected to the horizontal folding line 11 on one side thereof, and a cut 13b extending in parallel with the horizontal folding line 11 along the end of the notch 13a. And a vertical fold line 13c that extends to the lower edge of the flap crossing the end of the cut 13b is provided, and the plate surface portion below the notch 13a can be bent at the vertical fold line 13c.

  On the other hand, the upper side of the long side wall 2 has a rectangular upper lid 14 projecting through the horizontal folding line 10 with the same dimension as the width of the short side walls 3, 4, and the lower side of the short side wall 3 through the horizontal folding line 11. The trapezoidal bottom flaps 15 projecting in a size approximately half of the width of 4 are connected in series.

Further, the inner overlapping walls 16 and 17 project at the upper edges of the short side walls 3 and 4 through the horizontal folding lines 10 with substantially the same dimensions as the heights of the respective side walls (symbol T in the figure), and the horizontal folding lines at the lower edges. 11, substantially trapezoidal bottom flaps 18 and 19 projecting approximately half the width of the short side walls 3 and 4 are connected to each other.
Supporting pieces 16b and 17b are provided at the tips of both inner overlapping walls 16 and 17 via horizontal folding lines 16a and 17a. Further, the bottom flaps 18 and 19 are provided with diagonal folding lines 18a and 19a which are obliquely extended at an angle of 45 ° with respect to the horizontal folding line 11 with the corner connected to the horizontal folding line 11 as a starting point. The outsides of 18a and 19a are used as triangular adhesive margins 18b and 19b.

  Further, an insertion piece 14b protrudes from the entire periphery of the upper lid flap 14 via a folding line 14a, and an insertion piece 14b is formed on the horizontal folding line 10 at the upper edges of the long side wall 2 and the short side walls 3 and 4. The slits 20 to be engaged are respectively formed.

  From the punched substrate thus configured, the longitudinal folding lines 5, 6, 7 are bent outwardly to form the long and short side walls 1, 2, 3, 4 into a cylindrical shape, and the adhesive margin 8 that is connected to the long side wall 2 is provided. While sticking to the inner side surface of the short side wall 4, the slant folding lines 18a and 19a of the bottom flaps 18 and 19 provided continuously below the short side walls 3 and 4 are folded inward to give the adhesive margins 18b and 19b to the long side wall 1 2 can be formed by folding them on the outer side surfaces of the bottom flaps 13 and 15 provided continuously below the two and attaching them together.

  When the formed assembly box is folded so that the vertical folding lines 5 and 7 are located at both ends, as shown in FIG. 2, the bottom flaps 18 and 19 are folded inward from the diagonal folding lines 18a and 19a, The bottom flaps 13 and 15 are folded inward of the box with the horizontal folding line 11 as an axis, and the lower plate surface portion of the bottom flap 13 is folded along the vertical folding line 13c to be thin and flat before use. The assembly boxes can be stacked and stored or transported.

  When using the assembly box, first, by pressing both ends along the vertical folding lines 5 and 7 in the folded state, the bottom flaps 13, 15, 18 and 19 folded inward of the box are As shown in FIG. 3, the box is assembled in a three-dimensional shape having an upper opening. In this state, a rectangular bottom flap 13 overlaps the entire upper surface of the bottom flaps 15, 18, 19, and the gaps between the flaps are closed by the bottom flap 13, so that the bottom of the assembly box is completely sealed. Further, the bottom flap 13 overlaps the bottom flaps 15, 18, and 19 to increase the rigidity of the bottom portion of the box.

  Next, as shown in FIG. 4, the inner overlapping walls 16 and 17 are folded at the horizontal folding line 10 to fold both overlapping walls on the inner side surfaces of the short side walls 3 and 4, and the support pieces 16 b and 17 b are folded to the horizontal folding line 16 a, The two pieces are folded on the upper surface of the bottom flap 13 by bending at 17a. In this state, the assembly box has a wide open top as shown in FIG. 5 and can accommodate waste documents. The short side walls 3 and 4 and the inner overlapping walls 16 and 17 are exactly overlapped. Since it rises double from the bottom of the box, the strength against the load applied from the inside and outside of the box is extremely high, and it is difficult to deform.

  Then, when the waste document is stored in the full box, as shown in FIG. 6, the inner lid flap 12 is folded on the opening surface, and the outer lid flap 14 is further folded thereon, and the periphery of the outer lid flap 14 If each insertion piece 14b is inserted into and engaged with each slit 20, the opening surface of the box is closed by the double-folded inner and outer lid flaps 12, 14, and the inside of the assembly box can be completely sealed. . Since the opening surface is closed by the inner lid flap 12, and the insertion piece 14b is inserted into the slit 20 at the upper edge of both the short side walls 3 and 4 and closed. There is no risk of the documents stored from the upper edge breakout.

  As described above, the assembly box of the present invention can be folded and stored and transported before use, and can be assembled from a folded state by a simple operation. In the assembled state, the bottom flaps 13, 15, 18, and 19 of the box do not overlap even if they overlap and store heavy objects, and the short side wall 3 that rises exactly from the bottom of the box, 4 and the inner overlapping walls 16 and 17 exhibit high rigidity. In addition, the flap overlaps at the lid and bottom of the box, completely closing the gap around the box and completely sealing the inside of the box, so that the waste documents stored in the box will not come out, Documents stored from outside cannot be taken out.

  The assembly box of the present invention can be used not only for discarding documents but also for storing, transporting and packaging various items. Further, the insertion pieces 14b provided on the outer lid flap 14 may be provided only on two opposite sides of the outer lid flap 14 so as to engage with the slits 20 provided on the upper edges of the short side walls 3 and 4, respectively.
