Description

[Detailed description of the invention] The present invention relates to a packaging box, and its purpose is to simplify assembly and disassembly operations by using strong paper materials such as cardboard, and to integrally assemble a reinforcing frame on the inner wall surface. In particular, it is an object of the present invention to provide a packaging box that retains the robustness of a box shape and also has the ability to be moved by a forklift. Considering air containers used for air cargo as their main field of use, air transport is extremely expensive compared to normal cargo transport, so the general requirements are robust, lightweight, foldable, and easy to handle. A particularly important requirement is to obtain maximum robustness at the lowest possible weight while being inexpensive. As a measure to reduce weight, paper materials such as cardboard are used as widely as possible. Conventional paper packaging boxes have been made of resin-treated paper that is impregnated with a synthetic resin liquid and hardened in order to increase the strength of the fabric itself. Processed paper is a specially processed product that is extremely expensive, and this high cost has been accepted in order to make it as light as possible. Therefore, the present invention utilizes inexpensive paper materials such as ordinary cardboard that is not treated with resin, and combines it with a wooden reinforcing frame that does not inhibit the storage capacity of the interior space, thereby reducing the strength and lightness. This is an attempt to drastically reduce costs.

To explain the embodiment of the present invention according to the attached drawings, 1 consists of sequentially bending each component piece punched out of a material such as ordinary corrugated cardboard material that is not subjected to resin processing, and connecting and fixing adjacent overlapping parts. It is a box assembled as a rectangular parallelepiped with a chamfered front edge and a pentagonal cross section. The box body 1 is integrally fixed by nailing means or the like to the surface portion 32 of a known wooden pallet 31 in which a fork insertion hole of a forklift is previously drilled in the side circumferential surface for movement.

The main components for constructing the box 1 are the bottom plate component 2, the left and right side components 77', the front and back components 19, 20, and the ceiling component 21. Reinforcement frame 26 installed closely against the wall surface
It is integrally assembled using a connecting tool 33.

The bottom plate component piece 2 includes, for example, a front folding piece 4 and left and right folding pieces 5, 5', which are integrally and bendably connected to the periphery of the bottom plate portion 3 that matches the surface shape of the pallet 31. 66' is a fold line a at the front end of the left and right folding pieces 5, 5.
This is a folded hem piece that is continuous with the front folding piece 4 and separated from the front folding piece 4 by the cutting line b. If necessary, a folding piece similar to the front folding piece 4 may be formed on the rear edge of the bottom plate portion 3 as well. The left and right side pieces 7, 7' are formed symmetrically, and only one will be explained as follows.
Folded hem pieces 9 to 1 are provided at each edge of the front, back, ceiling, and sloped surface between the ceiling and the front in the side part 8.
2 are arranged in a row so as to be freely foldable, and the folded piece 43 of the hem piece 10
The folded hem pieces 11 respectively form cut surfaces 13 and 14 for avoiding overlapping when the adjacent corresponding parts are folded inward. Reference numeral 15 is a horizontally long rectangular reinforcing plate that is bent inward from a fold line E at the center in the transverse direction, and is connected to each fold line c, c' of the left and right side folding pieces 5, 5' in the bottom plate part 3. After arranging the fold line E in a substantially overlapping state, the inner fixing part 16 has rectangular perforations 17, 17 formed along the fold line.
are glued and fixed, and on the other hand, the folded part 18 is placed outward from the folded line.
Leave it loose. 19 and 20 are the bottom plate part 3
The lengths of the front and back edges of the left and right side sections 8, 8' are made to match, and the lengths of the front and back edges of the left and right side sections 8, 8' are also matched with each other. 2
Reference numeral 1 denotes a ceiling component, with left and right side parts 8, 8'
Three parallel fold lines F, G, and H are provided in the oblong fabric that spans and covers the ceiling and sloped surfaces of
Ceiling part 22, inclined surface part 23, and front and rear folding pieces 2
4,25 are formed.

Reference numeral 26 is a reinforcing frame made of wood installed along the inner wall surface of the box body 1, and there are inverted U-shaped side frames 27 parallel to the vertical direction from both ends of the ceiling at the left and right side sections 8 and 8'. The lower end leg of 27' is connected to the reinforcing plate 15,
Square perforation part 17, 17, 17', 1 in 15'
7' so as to stand up, and after connecting the front upper end corners of both side frames 27, 27' integrally with the connecting rod 28, the front end is attached to the upper surface of the approximately center of the connecting rod 28. An inverted L-shaped central reinforcing rod 29 is installed to support the section 30. The lower end leg of the reinforcing rod has a rectangular perforated part 17'', which has the same principle as the rectangular perforated parts 17, 17, 17', 17' into which the lower end legs of the side frames 27, 27' are fitted and installed, in the center of the bottom plate part 3. It is best to place it on the inside of the rear edge.

Reference numeral 33 denotes a connector to be used at a desired connection/fixation location when sequentially assembling each component of the box 1. A back metal fitting 34 on which a mounting plate 35 with claws is installed so that the internal threaded cylindrical part 36 protrudes from the inside of the inner piece S to the outer surface, and a hole 37 of the outer piece T is fitted into the internal threaded cylindrical part 36 that protrudes. After that, from the outside,
Engagement part 4 that can be tightened with a removable lever 42
The outer threaded rod 41 of the front metal fitting 38 installed on the rotary disk 39 forming a symmetrical shape of 0,40' is screwed and fixed, and the box body 1 is assembled.
This completes the assembly of the

As described above, the present invention has front and side folding pieces arranged in a bendable manner on the periphery of the bottom plate fixed to the surface of the pallet, and a folding hem piece is also attached to the side folding pieces. , reinforcing plates with square perforations are glued and fixed on the left and right sides, the U-shaped left and right side frames are connected to the connecting rods, and the front end is suspended and supported on the upper center surface of the connecting rods. After the reinforcing frame consisting of the central reinforcing rod is installed upright on the bottom plate, the left and right side component pieces are made by bending the front and rear folded hem pieces, the ceiling folded hem piece, the inclined face folded hem piece inward, and The front and back components are assembled with the ceiling component, and the overlapping joints of each can be integrally fixed using connectors, so that the reinforcing frame 26 inside the box body 1 is tightly attached to the inner wall surface. It can be installed without causing a decrease in storage space.
In particular, the reinforcement effect is remarkable for the side panels 7, 7' and the ceiling component 21, which require strength, so the walls are constructed using inexpensive materials that have overall lower paper strength compared to conventional materials. Not only can it be possible to significantly reduce costs, but also the reinforced frame frame 2
6, this is an excellent idea that brings about various effects such as a simple structure and the ability to be assembled from easily available materials, making it possible to supply quickly and reliably.
