Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a packaging box for packaging and transporting a disc-shaped insulator porcelain body, which minimizes the packaging volume.

(Prior Art) When packaging items that are easily damaged and have a protrusion on a part of their shape, if the packaging is hung in order to prevent damage, the packaging volume becomes excessive. However, if the package is packed too tightly, there is a risk of damage due to impact during transportation.

For this reason, conventional packaging for easily damaged items has been attempted by placing a hollow box frame made of folded cardboard inside a cardboard box as a shock absorber in the extra space of the packaging box to reduce the impact. (Jikko 40-
Publication No. 30637) This type of packaging box has extra space in the packaging box, so the packaging volume is correspondingly large, and although it is good for small items such as TV cathode ray tubes, it is not suitable for items such as insulator porcelain. If the package is too heavy, the internal shock absorber will not be able to absorb the impact during transportation of the package, resulting in damage to the product.

Furthermore, in order to reduce the packaging volume, there is also a packaging box as shown in Japanese Utility Model Publication No. 58-56230 as a packaging for television cathode ray tubes. This product is specifically designed for television cathode ray tubes, but the notches provided in the reinforcing member are complicated, making it expensive even though it is only used for one-time transportation.

(Problems to be Solved by the Invention) The insulator porcelain packaging box of the present invention has the drawback that conventional packaging boxes of this type have excess space, and is not suitable for packaging heavy items in terms of impact force. In addition, it solves the problem of complicated reinforcing members, makes it safe for heavy and easily damaged items such as insulator porcelain, minimizes the packaging volume, and makes it easy to install reinforcing members inside. This is what we are trying to do.

(Structure of the invention) (Means for solving the problem) The insulator porcelain packaging box of the present invention has a fixing plate 1, which forms an enclosure-like fixing frame 2 with four fixing plates, and a head of a disk-shaped insulator porcelain body 3. A cut-out hole 5 is made in the center of the fixing plate 1 to fix the disc-shaped insulator porcelain body 3 in a posture in which the shaped part 4 is inserted toward the inside of the fixing frame 2. A notch 7 and a bending line 8 are connected to the outer edge 6, and a part of the fixing plate 1 forms a folding piece 9, and a column-shaped buffer is provided in the space inside the fixing frame 2. It is essential that the unit packaging space 10 is continuously provided separated by a partition plate 11, and the disc part 1 of the disc-shaped insulator porcelain body 3 fits into the fixed frame 2.
2 is a disc-shaped insulator porcelain body 3 supported by a buffer body 10;
It is more preferable to construct a unit packaging space in which one each is inserted from the top and bottom.

The four fixing plates 1 may be separated individually or may be connected laterally.

The cut-out hole 5 may be hollowed out, or the notches 7 may be cut radially and fit into the slot.

The buffer body 10 may be made of corrugated paper,
It may be made of a material such as expanded polystyrene or expanded polyethylene and molded into a shape that matches the shape of the item to be packaged. Furthermore, when the buffer body 10 is shaped like a frame, the buffering force is increased by inserting an intermediate support plate 13 in the form of a support plate inside.

(Function) The insulator porcelain packaging box of the present invention forms an enclosing fixing frame with four fixing plates, and inserts the disk-shaped insulator porcelain head toward the inside of the fixing frame to form a disk-like shape. A cut-out hole for fixing the insulator porcelain body is made in the center of the fixing plate, and a cut and a bending line are connected between the cut-out hole and the outer edge of one fixing plate, so that a part of the fixing plate is Since the disc-shaped insulator porcelain body is formed into folded pieces, when packaging the disc-shaped insulator porcelain body, fold the folded pieces of each fixing plate from the bending line, and then move the head of the disc-shaped insulator porcelain body towards the inside of the fixing frame. Insert it into the cut hole, then return the folded piece to fix the disc-shaped insulator porcelain body. Thereafter, a column-shaped buffer is inserted into the space inside the fixed frame, and the head of the disc-shaped insulator porcelain body is brought into contact with the column-shaped buffer to absorb the impact when the packaging box is dropped. A plurality of such unit packaging spaces are provided in the packaging box with partition plates in between, and the optimal number of unit packaging spaces is determined depending on the weight and dimensions of the disc-shaped insulator porcelain to be packaged and the packaging volume of the entire packaging box. can be determined. The packaging box has a bottom, and the lid is determined in consideration of conditions such as the weight and dimensions of the disc-shaped insulator porcelain body to be packaged, the strength of the packaging box as a whole, and the packaging volume.

Furthermore, the weight of the disc-shaped insulator porcelain body to be packaged,
Depending on the dimensions, two disc-shaped insulator porcelain bodies can be filled in addition to the disc-shaped insulator porcelain body which is inserted into the cut hole with the head facing inward of the fixing frame and fixed. In that case, one disc-shaped insulator porcelain body is placed at the bottom of the unit packaging space, a buffer is placed on top of the disc, and then the heads of four disc-shaped insulator porcelain bodies are placed on the fixed frame. They are each fixed in a position where they are inserted facing inward of the fixing frame, and one disk-shaped insulator porcelain body is further inserted from above so that the head portion is in contact with the buffer body. In this packaging form, the upper and lower disc-shaped insulator porcelain bodies are supported by a fixed frame, and the head part is in contact with the cushioning body, so that even if the packaging box falls, the packaged insulator porcelain bodies will not be damaged. become.
This form results in the densest packing.

(Example) Example In a unit packaging space with internal dimensions of 350 mm x 350 mm x 251 mm, a cut hole with a diameter of 78 mm was inserted into the head of a disc-shaped insulator porcelain body with a cap diameter of 251 mm, a head diameter of 77 mm, and a height of 110 mm. Four fixing plates with a side of 251 mm provided in the center are fitted into the cut-out holes of a fixed frame formed like an enclosure, as shown in Figure 1. A cushioning body made of two layers of cardboard was inserted in the shape of a square prism with a length of 162 mm. In addition, one insulator porcelain body is placed in advance at the bottom of the fixed frame, and a buffer body is placed on top of it, and one more insulator porcelain body is placed symmetrically with this as shown in Figure 2. A total of six insulator porcelain bodies were accommodated in the unit packaging space.

In this way, nine unit packaging spaces divided by partition plates are arranged in a 3 x 3 arrangement, with a total of 54 boxes per stage.
216 insulator porcelain bodies were packaged, and this was further stacked in 4 layers to make 216 insulator porcelain bodies into one package.
The weight of this package was 800Kg/package.

(Effects of the invention) The insulator porcelain packaging box of the present invention has the drawbacks of conventional packaging boxes of this type, such as a large amount of excess space and a large packaging volume, resulting in high shipping costs, especially for sea transportation. Insulator porcelain, which is different from hollow ones such as television cathode ray tubes, is not suitable for packaging heavy objects due to its impact force and also has the problem of complicated reinforcing members. It has the excellent advantage of being able to safely store heavy and easily damaged items, such as items such as , while minimizing the packaging volume, reducing logistics costs, and requiring simple reinforcing members to be installed inside. This invention has an extremely significant contribution to the development of industry.
