Abstract

[PROBLEMS] To ensure the necessary and sufficient strength by only assembling without using an adhesive or the like, and in regard to processing, only stamping and no pasting are required, so the processing cost is greatly reduced. Corrugated water tank is provided. A ruled line portion is folded, and a locking projection is inserted into a locking hole and locked. Since the through hole for the lock has a double structure with the recess 11 for strengthening the lock, it is extremely difficult for the hole to become large due to an impact and to release the lock. Locking is performed fairly firmly because it uses the downward repulsive force of the double ruled line 16 and the lateral repulsive force of the reverse folding ruled line 14. For this reason, the lock portion will not come off unless a force is applied directly in the direction opposite to the repulsion. Originally, the small wrapping portion 13 is designed to be on the upper side. However, if a strong lock is desired, the large wrapping portion 12 can be assembled on the upper side.

Description

  The present invention relates to a form that facilitates complicated assembly when a completely water-resistant water tank is formed using corrugated cardboard to which resin is bonded.

  There are many forms of assembly boxes that do not leak water with corrugated cardboard to which polyethylene film is bonded. This is because recyclable corrugated cardboard has been reviewed as an alternative to foamed polystyrene and plastic cases. As for home delivery, when shipping shellfish such as fresh fish with ice stuffing, the mainstream is polystyrene foam, but the processing of the foamed polystyrene on the receiving side is also a problem because it takes up space.

  In order to make it completely waterproof and to maintain strength, a complicated lock structure must be taken and it takes time to assemble. Moreover, the corrugated cardboard bonded with the polyethylene film is hard and requires a force to bend itself. Therefore, the ability as a substitute for polystyrene foam is latent because of the labor. However, if it can be easily assembled and disassembled, the box can be assembled at the required timing, so that the storage space can be greatly reduced. That will expand the possibilities of corrugated cardboard in the future and is a great attraction.

  In Patent Document 1, it is difficult to insert a folded portion for locking. In addition, close double reverse folding must be performed, and the carding process is also difficult because the corrugated sheet is easily broken.

  In Patent Document 2, an adhesive such as hot melt must be used to fix the four corners, which causes pasting. As a result, the cost will increase.

  The present invention has the main feature of a form that allows easy assembly and disassembly as a water tank corrugated cardboard without using an adhesive.

  In the present invention, the assembly and disassembly of the water tank form corrugated cardboard is facilitated, so that the box assembly at the necessary timing is possible. Further, the necessary and sufficient strength can be ensured only by assembling without using an adhesive or the like. As for processing, only punching is required, and no pasting is required, so the processing cost is greatly reduced.

  In addition, scallops packed in ice were conducted as a courier shipping experiment. As a result, no water leakage was observed, and it was confirmed that, as an alternative to polystyrene foam, the function of full waterproofing was fully exhibited and strength problems were also achieved.

FIG. 1 is a developed plan view when the box is disassembled. FIG. 2 is an assembling diagram. FIG. 3 is an assembly completion drawing.

  In the developed plan view of FIG. 1, the ruled line portion is folded, and 10 projections are inserted into 15 through holes and locked. Since the 15 through-holes have a double structure with 11 indentations, it is extremely unlikely that the holes will become large due to impact and the lock will be released.

  Locking is performed fairly firmly because it uses the downward repulsive force of the double ruled line 16 and the lateral repulsive force of the reverse folding ruled line 14. For this reason, the lock portion will not come off unless a force is applied directly in the direction opposite to the repulsion.

  Although the upper and lower relations of 12 and 13 are originally designed so that 13 comes up, if a strong lock is desired, 12 can be assembled up as shown in FIG.

  The width of the folding portion is 17, but the longer it is, the stronger the lock strength is, but it becomes an obstacle when packing. It is desirable to take long as long as there is no obstacle to packing.

Claims (1)

  In the corrugated cardboard form in which the bottom and sides are connected to each other for waterproofing, double-folding is performed on the top surface of the box, and the repulsion in the lower and lateral directions of the cardboard is applied to the lock holes on the inside of the side. A form of a packaging box that is firmly locked by use.
