A concave cutout for attaching the handle member 7 is provided in the center upper portion of the swing side plate 3 in advance, and after the handle member 7 is arranged at that position, the molding member 5a is slid and fitted. Therefore, no hook or adhesive is required to fix the handle member 7.

  Further, a half-cut hinge line 27 is formed above the swinging side plate 3 so as to leave the inner substrate 10b, and the box 1 is centered on the hinge line 27 as shown in FIG. Swings inward. The distance from the hinge line 27 to the upper end of the molding member 5a is approximately the same as the thickness of a cushion mat 28 that will be described later.

  As shown in FIG. 5, the bent side plates 4 and 4 use the plastic corrugated cardboard with the core member 10 c facing in the vertical direction, and are integrated with the bottom plate constituting plate 13 that overlaps the bottom plate constituting plate 12. It is connected to. A molding member 5a is fitted to the upper edge of one bent side plate 4. The fitting structure is the same as in the case of the swing side plate 3 and the molding member 5a, and the description thereof will be omitted.

  On the other hand, a dedicated molding member 5 b corresponding to the lid plate 8 is fitted to the upper end edge of the other bent side plate 4. That is, as shown in FIG. 9, the molding member 5b has the same outer dimensions as the molding member 5a, but the partition wall 29 is formed in the center in the height direction, and the vertical axis is symmetrical about the partition wall 29. is there. Therefore, there is a cover plate opening 260 for one plastic cardboard on the upper surface. Then, one bent side plate 4 having a bent piece 24 formed at the upper end is fitted in the lower half space of the molding member 5b, while the upper half space of the molding member 5b is V with respect to one side of the lid plate 8. The bent piece 24 is formed and fitted into a mounting piece 31 provided continuously through a hinge wire 30 by a groove. Therefore, the cover plate 8 is fixed to the molding member 5b via the attachment piece 31, and can freely rotate around the hinge line 30 as shown by the one-dot chain line and the two-dot chain line in FIG.

  As shown in FIG. 5, the bent side plates 4 and 4 have two upper and lower hinge lines 32 and 33 formed by half cut leaving the inner substrate 10 b and the outer sides of the hinge lines 32 and 33 in the center in the height direction. The half-cut hinge wire 34 is left leaving the substrate 10a, and is bent in a so-called folding screen, so that it can be bent in the height direction. The upper hinge line 32 is at a position lower than the hinge line 27 of the swing side plate 3 by the thickness of one plastic cardboard (swing side plate).

  The bent side plates 4 and 4 and the swing side plates 3 and 3 are connected to each other by fitting corner members 6, 6... At the abutting portions of the four molding members 5a and 5b and rigidly joining them into a square frame shape. .

  As described above, the cover plate 8 has the attachment piece 31 on one side via the hinge wire 30 having a V-shaped groove. The V-shaped angle of the hinge wire 30 is set to be slightly larger than 90 degrees in a state where the cover plate 8 and the mounting piece 31 are deployed at 180 degrees, so that the mounting piece 31 and the cover plate 8 bend to 90 degrees or less. It has become. By doing so, when the cover plate 8 is closed as shown by the one-dot chain line in FIG.

  On the other hand, a locking means is provided on one side of the lid plate 8 opposite to the hinge line 30. As shown in FIG. 10, the locking means includes a locking main piece 35 that is thermally deformed downward on one side of the lid plate 8 by 90 degrees, and a distal end of the locking main piece 35 that is further heated inward by 90 degrees. It comprises a deformed locking claw 36. The length of the locking main piece 35 is set to be substantially equal to the height of the molding member 5a. Therefore, with the lid plate 8 closed, the locking claw 36 is below the molding member 5a as shown in FIG. Engage with the edge to prevent the lid plate 8 from opening. In this way, 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 pawl 36 is engaged with the lower edge of the molding member 5a to prevent the cover plate 8 from opening, there is no failure with a simple structure, and it is effective as a cost control measure.

  Next, how to use 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 the swing side plates 3 and 3 stand upright. Then, the stopper pieces 20 of the swing side plates 3 and 3 are bent from the hinge wire 19 and overlapped on the bottom plate constituting plate 12, and their end surfaces abut against the end surface of the stop plate 14. In this state, even if an inward force acts on the swing 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 it 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.

  When packing the transported object 37 such as a computer or a display in this state, the transported object 37 is wrapped with a buffer mat 28 as shown in FIG. Tie on top of two. Therefore, it is not necessary to fill the box 1 with a cushioning material such as a foam and fix the article 37 to be transported. Further, since the bottom plate 2 is penetrated by the metal cage 15 as described above, even if static electricity is generated inside the box 1, the bottom plate 2 comes out from the cage 15. Next, the lid plate 8 is closed, and the locking claw 36 of the locking main piece 35 is engaged with the lower edge corner portion of the molding member 5a.

  The buffer mat 28 uses so-called quilting in which a core material such as cotton is put into a bag of cloth such as cotton and stitched, or a bubble sheet material disclosed in Japanese Patent Application No. 11-126336 related to the applicant's application. Good. As shown in FIG. 11, the bubble sheet material of Japanese Patent Application No. 11-126336 uses a bubble sheet 39 formed by forming a large number of closed cell bodies 38 in which gas is sealed on a synthetic resin film, and a cover sheet 40. Then, the cover sheet 40 is superimposed on one side and / or both sides of the air bubble sheet 39, and the needle holes that pass through the air bubble sheet 39 and the cover sheet 40 and are continuous in a dotted line so as to cross the closed cell 38 of the air bubble sheet 39. And then stitched together through a thread through the needle hole to form a folded suture line 41, which is thinner and lighter than conventional quilting and has a high cushioning property. is there.

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

  Next, the tip of the stopper piece 20 of the swinging side plate 3 is lifted with a finger to disengage from the stop plate 14, and the swinging side plates 3 and 3 are turned inward as shown by a two-dot chain line in FIG. Then, as shown in FIG. 5, the bent side plates 4 and 4 lose their support and are naturally bent into a V shape. When the molding members 5a and 5b are pushed down in this state, the claw pieces 7c of the handle member 7 engage with the engaging portions 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. Further, the fixing band 9 is sandwiched between the bottom plate 2 and the side plates 3 and 4 and enters the slight gap due to the elasticity of the side plates 3 and 4 and the overlapping of the side plates 3 and 4, so that the folding of the box 1 is not hindered. .

  Next, the upper surface of the swinging side plate 3 of the folded box 1 is used as a storage space, and the buffer mat 28 previously folded is placed in 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 the folded state, there is no problem with the storage place of the buffer mat 28, and the buffer mat 28 is lost when the box 1 is folded and transported. do not do.

Next, an effective utilization method of the present invention will be described. When a precision machine such as a computer or a measuring device breaks down, in a conventional system in which an engineer repairs on a business trip, travel time is wasted and processing capacity per engineer is reduced. Such a problem can be solved by the following systems (1) to (4) using the box 1 of the present invention.
