Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box which can be folded into a flat and compact shape from an assembled state.

[0002]

2. Description of the Related Art Conventionally, there is one bottom plate and four side plates,
Of the side plates, two opposing plates are swinging side plates that are rotatable inside the box with the upper edge being a bending center, and the remaining two plates have a so-called folding screen structure that is bendable in the height direction. Is a collapsible box, for example,
No. 10132 and the like. When assembling this foldable box from the flat folded state to the use state, lift the upper edge of the box and raise the bent side plate of the folding screen structure vertically, erect the remaining two swinging side plates,
It is a structure in which the bent portion of the bent side plate is locked from the inside by the both side edges of the swinging side plate.

[0003]

The foldable box as described above has an advantage that it can be folded and transported efficiently or stored in a small space. However, conventionally, it was necessary to pack a cushioning material into a box in an assembled state in order to protect an object to be conveyed, and such an advantage was reduced by half. In other words, in order to avoid wasting the cushioning material, if you try to return the used material together with the box, the box will not fold, and even if the box is folded and stored, if the storage space for cushioning material is added separately, the result will be It does not save space. On the other hand, if the cushioning material is disposable, it is a major negative factor for the problem of garbage, and the cost increases due to the disposable cushioning material.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and has a bottom plate and four side plates, of which two opposing ones are turned inside the box with the upper part bent at the center. A fixed band is attached to a bottom plate in a foldable box that is a movable side plate, and the remaining two sheets have a so-called folding screen folding structure and are bendable in the height direction. The present invention provides a foldable box that fixes the object to be carried on the bottom plate with the fixing band being sandwiched between the bottom plate and the side plate in the folded state.

[0005] By fixing the transported object with the fixing band, there is no need to pack the cushioning material into the box, and since the fixing band is sandwiched between the bottom plate and the side plate in a folded state, the box can be fixed. There is no need to pull out the fixed band each time it is folded.

Further, as described in claim 2, it is preferable that a storage space is provided above the swinging side plate in the folded state, and a buffer mat for wrapping a load is stored in the storage space. By doing so, there is no risk of losing the buffer mat and there is no problem in the storage space of the buffer mat.

As described above, one side of the cover plate 8 is thermally deformed to form the downward locking main piece 35, and the tip of the locking main piece 35 is thermally deformed to form the inward locking claw 36. If the stop claw 36 is engaged with the lower edge of the molding member 5a to prevent the cover plate 8 from opening, it is effective as a simple structure without failure and as a cost control measure.

Next, a method of using the box 1 will be described. In the assembled state as shown in FIG. 1, the bent side plates 4 and 4 extend straight and vertically, and the swing side plates 3 and 3 stand upright. Then, the stopper pieces 20 of the swinging side plates 3 are connected to the hinge wires 19.
, And overlaps the bottom plate constituting plate 12, and its end face abuts against the end face of the stop plate 14. In this state, even if an inward force acts on the swinging side plates 3 and 3 as shown by arrow F in FIG. 6, the stopper piece 20 hits the stop plate 14 and opposes the force, so that the stopper piece 20 does not move. Further, since the swing side plates 3 and 3 are in contact with the vertical plate 11 of the bottom plate constituting plate 12, they do not move outward.

In this state, when the transported object 37 such as a computer or a display is packed, the transported object 37 is wrapped by the buffer mat 28 shown in FIG. 37 is tied on the bottom plate 2. Therefore, there is no need to fill the box 1 with a cushioning material such as a foam to fix the load 37.
Further, since the bottom plate 2 is penetrated by the metal studs 15 as described above, even if static electricity is generated inside the box 1, the bottom plate 2 is pulled out of the studs 15 to the outside. Next, the cover plate 8 is closed and the locking main piece 3 is closed.
5 is engaged with the lower edge corner of the molding member 5a.

The cushioning mat 28 is a so-called quilt made by putting a core material such as cotton into a cloth bag made of cotton or the like and sewing the bag, or a Japanese Patent Application No. 11-1263 filed by the present applicant.
No. 36 bubble sheet material may be used. Japanese Patent Application No. 11-
As shown in FIG. 11, the bubble sheet material of No. 126336 includes a bubble sheet 39 formed by forming a large number of closed cells 38 in which a gas is sealed on a synthetic resin film, and a cover sheet 4.
0, the cover sheet 40 is superimposed on one side and / or both sides of the bubble sheet 39, and a dotted line penetrates the bubble sheet 39 and the cover sheet 40 and crosses the closed cell body 38 of the bubble sheet 39. A continuous needle hole is formed, and furthermore, a thread is passed through the needle hole and the two are sewn together to form a folded suture line 41, which is thinner and lighter than conventional quilting and has high cushioning properties. There is a feature.

Next, when the box 1 in the assembled state is folded, first, the locking claw 36 is detached from the molding member 5a while elastically deforming the locking main piece 35, and the cover plate 8 is opened. 9, 9 is loosened and the transported object 37 is taken out, and the buffer mat 28 is removed from the transported object 37. The removed cushion mat 28 is folded in a predetermined form.

Next, the tip of the stopper piece 20 of the swinging side plate 3 is lifted up with a finger to disengage with the stop plate 14, and the swinging side plates 3 and 3 are turned inward as shown by the two-dot chain line in FIG. Let it. Then, as shown in FIG. 5, the bent side plates 4 and 4 lose their support and bend naturally into a horizontal V-shape. In this state, the molding member 5
When a and 5b are pushed down, the claw piece 7c of the handle member 7 is engaged with the locking portion 16 of the vertical plate 11 of the bottom plate 2 as shown in FIG.
Therefore, the box 1 is locked in the folded state of FIG. In addition, the fixing band 9 is sandwiched between the bottom plate 2 and the side plates 3 and 4 and enters a slight gap due to the elasticity of the side plates 3 and 4 and the overlap between the side plates 3 and 4, so that the folding of the box 1 is not hindered. .

Next, using the upper surface of the swinging side plate 3 of the folded box 1 as a storage space, the buffer mat 28 folded earlier is put into the storage space as shown by a two-dot chain line in FIG. If the cover plate 8 is closed in this state, even if the box 1 is stored in a folded state, there is no trouble in the place where the buffer mat 28 is stored, and even when the box 1 is folded and transported, the buffer mat 28 is lost. do not do.

Next, the effective use of the present invention will be described. When a precision machine such as a computer or a measurement device breaks down, a conventional system in which an engineer performs repairs on a business trip wastes traveling time and reduces the processing capacity per engineer. Such a problem is caused by the box 1 of the present invention.
Can be solved by the following system using. In the following, it is assumed that transport of luggage between the repair company and the user is performed by a carrier. The repairer transports the box 1 of the present invention to the user in a folded empty state. The user who has received the box 1 assembles it, packs the defective product in the manner described above, and returns it to the repair company. The repairer repairs the defective product and transports it again to the user using the box 1 of the present invention. The user removes the repaired item from Box 1 and returns it to Box 1.
And return it to the repair agent.

According to the above-mentioned system, since the moving time of the engineer is not required, the processing capacity per engineer is improved. If there is a substitute during the repair period,
In the above, the substitute is packed in the box 1 and transported.

Thus, the box 1 of the present invention and the buffer mat 28
Can be used repeatedly, and the use of the fixing bands 9 and 9 eliminates the need for unnecessary cushioning material, so that there is no dust problem as in the case of disposing a paper cardboard box or cushioning material. In addition, since the entire box 1 and the fixing band 9 are made of polypropylene (synthetic resin), even if the life of the box 1 has expired, it can be turned into oil and recycled, which is extremely useful in preventing dust.

Although the present invention has been described with reference to the embodiment, it is needless to say that the present invention is not limited to the above embodiment. For example, in the embodiment, the swing side plate 3 and the vertical plate 11
Are disengaged, but in order to increase the load resistance,
Preferably, the swing side plate 3 and the vertical plate 11 are engaged to support the load. To this end, a protrusion 42 integral with the stopper piece 20 is cut into the swing side plate 3 side, and when the stopper piece 20 is bent as shown in FIG. 13, the protrusion 42 projects to the back side of the swing side plate 3. It is good to keep it. Then, a receiving hole 43 is formed in the vertical plate 11, and the projecting piece 42 is engaged with the receiving hole 43.

In the case where the protruding piece 42 is provided on the swinging side plate 3 and it may be caught by the fixing bands 9 and 9 to make it difficult to handle, as shown in FIG.
1, the inward projecting piece 420 is thermally deformed and protruded.
A receiving hole 430 is preferably formed in the swinging side plate 3, and the protruding piece 420 may be engaged with the receiving hole 430. In this case, the projecting piece 420 of the vertical plate 11 is also provided above the swinging side plate 3.
Is formed, the projecting piece 420 of the vertical plate 11 and the sub-receiving hole 431 are engaged with each other in the folded state, and the folded state of the box 1 is locked.

Further, in the embodiment, the stopper piece 20 of the swinging side plate 3 and the end face of the stop plate 14 abut against each other. However, the stop plate 14 is eliminated, and the stopper piece 20 is lengthened to make the left and right stopper pieces 20, Alternatively, the end faces 20 may be abutted against each other. In this case, the box 1 is folded such that the stopper piece 20 is folded on the swinging side plate 3, or the swinging side plate 3 and the stopper piece 20 are opened straight and the left and right swinging side plates 3, 3 are overlapped. Try to match.

In the embodiment, a stud 15 for stopping the bottom plate 2 is provided.
Is used to discharge static electricity to the outside. This is an embodiment of the technical idea in which a conductor is provided in the box 1 so as to penetrate the bottom plate 2 in the fixing area of the transported object 37 in the box 1. is there.

[0034]

According to the present invention, the object to be transported is fixed by the fixing band, so that it is not necessary to pack a cushioning material in the box to fix the object to be transported, and the bottom plate is folded. Since the fixing band is sandwiched between the base plate and the side plate, there is no need to pull out the fixing band each time the box is folded. Therefore, the merit of the foldable box, such as the ability to carry the article to be conveyed using the foldable box and efficiently transporting or storing it in an empty state, can be utilized to the utmost.

According to a second aspect of the present invention, the storage space above the swinging side plate in the folded state is used as a storage space, and the buffer mat for wrapping the transported object is stored in the storage space. There is an effect that there is no danger that the storage space for the buffer mat will be troubled.
