Description

[Detailed Description of the Invention] This invention relates to a packaging box for preventing dirt and damage to products such as ventilation fans when these products are stored and transported.

Conventionally, in this type of packaging box, a styrene holder or cardboard holder was inserted as a buffer between the outer box and the product to protect the product during transportation or handling, in order to reduce the impact on the product. .

Incidentally, such packaging boxes need to be disposed of when they are no longer needed by the user of the product, but styrene holders as cushioning materials are undesirable as they may cause pollution.
Further, the cardboard holder has a large volume to be disposed of as is, and it takes time and effort to disassemble it.

This invention aims to improve the above-mentioned drawbacks.

An embodiment of this invention will be described below with reference to FIGS. 1 to 4.

In the figure, 1 is an outer box whose top plate 1a, bottom plate 1b, and side plate 1C are made of one piece of cardboard, and is assembled into a square shape. A buffer plate is provided with a product placement piece 2b that extends toward the side and cooperates with the side plate 1C to form a buffer space A, and extends above the buffer space A; A cut groove extending downward from the upper edge of the side, 3 is a cut groove 2a of the buffer plate 2
It is a support plate made of corrugated cardboard with a cut groove 3a that engages with the buffer plate 2, and a product placement piece 3b extending outward from the upper end. Shape space B.

Reference numeral 5 denotes an upper buffer plate inserted between the product 4 and the upper plate 1a of the outer box 1, with both ends overlapped, and 6 an adhesive tape for bonding the opened upper plate 1a.

In this structure, if the product 4 is placed on the product placement pieces 2b and 3b extending from the upper ends of the buffer plate 2 and the support plate 3, which form buffer spaces A and B between the side plate 1C, In addition, shocks from below can be absorbed by the buffer spaces A and B.

Additionally, the upper buffer plate 5 can also absorb impacts from above.

In the above embodiment, the upper buffer plate 5 was provided to absorb the impact from above, but this may be omitted if the impact from above is rarely received.

As mentioned above, in the packaging box according to this invention, the buffer body is supported by the side plate of the outer box, one buffer plate, and a support plate made of cardboard, so the material cost and assembly cost for the buffer body is increased. In addition, the unnecessary packaging box can be easily unfolded into a plate shape, making it easy to dispose of.

Further, since the packaging box can be constructed of cardboard, it is possible to effectively reuse waste materials, and no pollution is generated due to disposal.

As described above, according to this invention, it is possible to provide a packaging box that is inexpensive and has great practical effects.

Claims (1)

[Scope of utility model registration request] In a packaging box in which the bottom plate 1b, the side plate 1C, and the top plate 1a are formed of a single piece of cardboard, the bottom plate 1b, the side plate 1C, and the top plate 1a extend inward from one edge of each side of a pair of opposing side plates 1C and cooperate with the side plate 1C. A buffer plate 2 is provided which forms a buffer space and has a product placement piece extending above the buffer space, and a cut groove extends downward from the upper edge of both ends of the buffer plate 2. A packaging box characterized by being provided with a support plate 3 made of a cardboard material that engages with the buffer plate 2a and spans the buffer plate 2, and has a product placement piece extending to the upper end.
