  However, if the entire circumference of the ventilator is covered with a cushioning material, the amount of cardboard used increases, which increases the cost. Furthermore, the inner dimensions of the cushioning material are designed to match the outer dimensions of the ventilator, and if the cushioning material is not fixed, the main body and the cushioning material will move inside the cardboard box in the packed state, and the ventilator body May be damaged. Moreover, when inserting an apparatus main body into a buffer material, there exists a problem that a buffer material moves and it is hard to insert.

  In addition, some recent ventilators exchange heat between the outside air and room air. In order to prevent condensation due to heat exchange, heat exchange type ventilators have a foam resin plate attached outside the box of the ventilator. A heat insulating layer is formed.

  When such a ventilator is stored inside the cardboard box, the bottom flaps and ceiling side flaps of the cardboard box come into direct contact with the wall surface of the packaging equipment. The ventilation device itself may be crushed by its own weight, and the heat insulation performance may be reduced.

  The present invention has been made paying attention to such a problem, and provides a low-cost ventilation device packaging device that does not damage the outer surface of the product, uses a small amount of cardboard, and is easy to store and take out. For the purpose.

According to a first aspect of the present invention, there is provided a corrugated cardboard box body in which a first flap that is a short flap and a second flap that is a long flap are formed to be bendable at an upper edge portion and a lower edge portion, respectively, A packaging device comprising a pair of cushioning materials for holding the device ,
The pair of cushioning materials are configured so as to be biased toward one side of the cardboard box body and store the device, and so that a space is formed on the other side in the cardboard box body,
Forming concave portions on the upper and lower sides of the space portion side of the pair of buffer members,
In these upper and lower recesses, the free end of the first flap formed on the upper edge part is hooked with the free end of the first flap formed on the lower edge part, respectively.
The pair of cushioning members are fixed to a side wall portion located on the opposite side of the first flap, and the space portion on the other side is secured by the first flaps on the upper edge portion and the lower edge portion. And

  The packaging device according to claim 2 of the present application is characterized in that in the packaging device according to claim 1, the packaging device has a guide inclined surface for inserting the device above the cushioning material.

According to a third aspect of the present invention, a fixture is protruded from a side portion of the device, and a recess for supporting the fixture is formed in a cushioning material that holds the device in a state separated from the bottom of the cardboard box body. It is characterized by.

A fourth aspect of the present invention is the cushioning material according to the first or third aspect, wherein the cushioning material has an inclined guide surface for housing the device on an upper surface portion of the cushioning material .

A fifth aspect of the present invention is the cushioning material according to the first aspect, wherein the concave portion supports the fixture projecting from the side wall portion of the device and supports the device by floating from the bottom of the cardboard box. Is formed .

  The shock-absorbing material according to claim 6 of the present application is the shock-absorbing material according to claim 5, supporting a fixture protruding from the side wall of the device, and floating the device from the bottom of the cardboard box. A concave portion to be supported is formed.

  According to the packaging device of claim 1 of the present application, a pair of cushioning materials are installed inside the cardboard box body, and the first flaps are hooked on the pair of cushioning materials, and the cushioning material moves within the box body. To prevent damage to the device body. In addition, when the first flap is hooked on the cushioning material, the pair of cushioning materials are pressed and fixed to one side of the cardboard box, so that the amount of cardboard used for the cushioning material can be reduced and the cushioning material is regulated. The cushioning material is prevented from moving in the box body, and damage to the device body can be prevented. Furthermore, it becomes easy to store the device when it is stored in the cardboard box body.
