Description

Statement

Assembled box technology

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large-sized prefabricated box such as a box, and more particularly to a prefabricated box suitable for a container for liquids.

Various types of foldable containers that can reduce the volume during collection have been proposed as a means of transporting liquid contents. As a first example, an L-shaped panel that is made of plastic and has a side wall, a bottom part, and a lid that constitute a prefabricated box body and accommodates a plastic inner bag inside (for example, Japanese Unexamined Patent Application Publication No. 9-202325).

However, this method is easy to assemble, but because the L-shaped panel has a low creep strength against the compressive pressure, it is usually used in a stacked state of about two to three steps. Considering storage, it can be used for small containers with a weight of around 100 kg, but cannot be used for large containers with a weight of 1 t or more.

As a second example, an interior tank is housed inside a box in which a corrugated steel panel made of hannel is erected, and when unnecessary, it is disassembled into a panel and interior bin to reduce the volume. 1 0—2 8 7 3 8 8).

However, this method is suitable for large containers, but its weight is increased due to its complicated structure, and the empty weight of a 1 t container is large if its content is high. Since the weight is around 250 kg, not only the transportation efficiency is reduced, but also the folding work is difficult, and special tools and personnel are required.

As a third example, there is a case in which the five sides of a hexahedral box are folded through hinges (for example, Japanese Patent Application Laid-Open No. Hei 7-251 838).极 It is easy, but the structure is complicated and heavy, and it is necessary to return it to a specialized manufacturer for repairs. However, there is a drawback that it increases.

As a fourth example, a resin-impregnated tubular bag made of hooded cloth, the upper part of which is a fixed flange with a lid, and the lower part of which is provided with a sealing material for attachment and detachment and a bottom member with a connecting part with multiple guides (See, for example, Japanese Patent Application Laid-Open No. 8-268491), but this method has many special parts, and is often used for folding work at the time of return. Since special tools and personnel are required for the equipment, it cannot be used for any other purpose.Furthermore, since the hooded cloth bag is exposed to the outside, for example, a forklift fork may hit during transportation. When the bag is made of hooded cloth, there is almost no trace of it, but even a small hole can leak liquid and cause a large loss, making it unsuitable for liquid transportation. In addition, when washing bags, sticky contents are extremely difficult to wash, so they cannot be used for applications other than limited applications.

As described above, the conventional large foldable container for liquids has a complicated structure with a box structure, which makes folding work difficult, increases empty weight and reduces transport efficiency, and the volume reduction rate is not sufficient. However, the bag structure has drawbacks such that it cannot be practically used for sticky contents, and is not suitable for liquid transportation because no trace of damage remains. Disclosure of the invention

A general object of the present invention is to solve the above-mentioned drawbacks of the conventional means, and to assemble a box that can be easily folded, has a light empty weight, has a large volume reduction rate, and is easy to repair. Is to provide the body.

In FIG. 2, reference numeral 1 denotes a side panel constituting the side wall of the box, and three or more (four in this embodiment) are used, and the bottom panel 5 shown in FIG. 7 and the lid 1 shown in FIG. Assemble 0 to form a box. Each of the side panel panels 1 has a column 2 made of a chevron at one end, and an engaging column 3 having at least two surfaces capable of engaging with the inner surface of the column 2 at the other end. The side walls are formed by alternately engaging the columns 2 and the engaging columns 3 of the side panel panels 1 with each other.

In this case, by making the shape of the side panel 1 slightly bulged outward, the thickness of the panel can be reduced, which is economical and can provide the desired strength. Make the length of the support 2 and the engagement support 3 longer than the length (height) of the side panel 1. The angled material serving as the support column 2 is not limited to a right-angled L-shape, but may be, for example, a corner-R shape or a chamfered shape as shown in FIGS. 5 (A) and (B). Although the above-mentioned engaging post 3 generally uses a hollow body to reduce the weight, it may have an irregular cross section as shown in FIGS. 6 (A) and 6 (B). Any shape that has at least two surfaces that engage with the surface may be used.

Engaging pieces 2a, 2a as shown in Fig. 4 are provided downward at the upper end of the column 2, and as shown by broken lines, the engaging columns 3 of the adjacent side panel panels 1 to be combined are engaged. It is configured to be stably held even when the lid 10 is not covered when each side panel 1 is erected on the bottom 5. The shape and the like of the engaging pieces 2a, 2a are determined by the shape and position of the engaging support, and are not limited to the illustrated example.

The bottom 5 and the lid 10 are provided with fitting portions 6 and 11 into which the strut 1 and the engaging strut 3 in a mated state are fitted. So that the support column 2 and the engagement column 3 are arranged at right angles, and when disassembled, each side panel 1 removed from the bottom 5 and the lid 10 is overlapped between the bottom 5 and the lid 1 (). It is configured to do so.

As shown in FIG. 7, the bottom part 5 has a substantially box shape with a peripheral wall, and the four corners are engaged. There is provided a fitting portion 6 with which the above-mentioned support column 2 and engagement support column 3 are fitted. The fitting portion 6 is formed as a fitting hole by providing an L-shaped protrusion 7 so as to face the corner. Further, the lid 10 shown in FIG. 8 has substantially the same configuration.

If necessary, a liquid inlet / outlet 8 provided with an on-off valve 8a and an external connection port 8b can be provided in at least one portion of the bottom 5 or the lid 10 (bottom 5 in the illustrated example), which will be described later. As shown in the figure, the liquid outlet 13 with the breaker 13a provided at least at one place of the film bag 12 (Fig. 9) housed inside the box is connected to the bottom 5 (or the lid 10). ) Can be used as a liquid box by connecting to the liquid entrance 8.

The material of the film of the bag 12 may be any material as long as the contents do not penetrate or deteriorate due to the contents. However, in the case of water-soluble contents such as food, linear low density polyethylene (L — LDPE) is suitable. Considering the possibility of pinholes, double bags are desirable. In this case, use of a multilayer film with a piercing strength polyimide layer and EP rubber layer for the film located outside prevents pinholes from being generated in the bag due to external impact. can do.

When used at low temperatures, a heat insulation layer 15 such as foamed plastic for heat insulation and bag protection may be provided on the inner surfaces of the side panel 1, the bottom 5 and the lid 10 as shown in Fig. 1. Good. Further, a hole for providing a forklift may be provided below the bottom 5 or a commercially available pallet may be used.

In use, first, the bottom 5 is placed on the ground or on a pallet, and the liquid outlet 8 of the bottom 5 is connected to the liquid inlet 13 of the bag 12, and then the column 2 of the side panel 1 and the adjacent side plate The struts 3 of the side panel 1 are staggered one by one at the four corners of the bottom 5 so as to alternately engage with the struts 3 of the panel 1, and the struts 2 of the side panel 1 adjacent to the engaging pieces 2a at the upper end of the strut 2 By engaging 3, the four side panel panels 1 are locked. Next, the external connection port 8b of the bottom 5 and the supply port (not shown) of the liquid to be filled are connected to connect the external connection. With liquid coming to port 8b, open and close valve 8a and fill Open the supply valve according to the rules and fill the bag 12 with liquid. While visually checking the filling amount or when a predetermined predetermined supply amount is supplied, the on-off valve 8a and the supply valve on the liquid side to be filled are closed, and the external connection port 8b and the liquid side on the liquid side to be filled are closed. Separate from the supply port. After checking the condition of the inside of the box, cover 10 is placed on the upper end of side panel 1, and support 2 and engaging support 3 fit into fittings 1 1 at the four corners of cover 10 and are fixed. Is done. In this state, the bottom 5 and the lid 10 are tightly bound with a belt or the like so that the side panel panel 1 and the bottom 5 and the lid 10 are not separated.

Upon folding after use, the reverse process of assembling may be performed. When discharging the contents, the lid 10 can be opened to check the discharge status of the contents.If the contents such as high-viscosity liquids are difficult to discharge, the side panel 1 Can be removed to squeeze out the contents remaining inside the bag 12.

When the discharge of the contents is completed, all the side panel panels 1 are removed, the side panel panels 1 are superposed on the bottom part 5, and the lid parts 10 are overlapped and bound by a belt or the like. By folding and bundling in this way, the box is reduced in volume to about 1/3 of its used volume.

In the final stage of discharging the contents, the film of the bag 12 may stick to the discharge port, making it difficult to discharge the contents reliably. A discharge nozzle with a breaker 13a as shown is fitted. Generally, prefabricated containers have many complicated structural parts such as hinges, special flanges, and support columns, and special equipment and techniques are required for folding work. Since it is necessary to repair the container, it has disadvantages such as costly and time-consuming repair. As a result, the turnover rate of the container decreases and the repair cost increases.

Since the prefabricated box body of the present invention is manufactured for each part, the compatibility is high. Even if a part is damaged, the parts need only be replaced, so that the rotation rate of the box body does not decrease. In addition, since the repair parts are also made in parts, they can be easily repaired by anyone without requiring specialized skills.

Also, by preparing various lengths of side walls and two bags, the internal volume of the container can be easily changed if necessary. Next, the present invention will be described in more detail based on examples, as follows, but the present invention is not limited to these examples.
