Description

[Detailed description of the invention] This invention relates to a cushioning material for packaging a ventilation fan, which is provided when packaging a ventilation fan, which has a front structure extending radially from the ventilation fan main body, into an outer box. It is something.

Conventionally, the ventilation fan of the above type is packaged by attaching the ventilation fan to a cushioning material made of rigid paper or the like.
A widely used method is to put the product inside the outer box along with cushioning material. The purpose of this is to maintain a strong relationship between the cushioning material and the ventilation fan and to provide sufficient cushioning, but since the outer box and the cushioning material are separate until the packaging is complete, a large space is required to store them. Not only that, but it also complicates the packing site and impairs work efficiency.

This invention can be attached to the outer box separately from the ventilation fan, and the protruding front structure of the ventilation fan is held by a retaining flap that can be formed by bending. To provide a cushioning material for packing a ventilation fan, which has an excellent cushioning function of keeping the ventilation fan in a restrained state by supporting the support of the ventilation fan, and which does not complicate packing work and is easy to store.

Next, the configuration of the present invention will be specifically explained based on an embodiment shown in the drawings.

The cushioning material as an application example of the present invention shown in the drawings is
By punching rigid paper etc. into the developed shape shown in Fig. 1 and bending it at the necessary points, it becomes the three-dimensional cushioning material shown in Fig. 2.
As shown in the figure, a shutter 2 protrudes laterally from a part of a main body part 1, and the front part of the main body part 1 has a front structure 3 projecting in the radial direction, and is used for packaging a ventilation fan 4.

The expanded shape of the cushioning material will be explained. In other words, it is a planar body in which one flap is connected to the upper end of each of the four continuous upright surfaces 5, and a fixing allowance 6 for assembly is connected to the end of the upright surface 5. The boundary of the upper surface 5 is formed by a straight vertically parallel folding line 7 and a hook-shaped cutting line 8 continuing horizontally and vertically. Each rising surface 5 has a generally convex planar shape with a wide portion and a narrow portion, and is arranged in an alternating manner in the vertical direction. The vertical dimensions of the rising surfaces 5 in the unfolded configuration are all the same and are slightly larger than the overall length of the main body portion 1 of the ventilation fan 4. Further, the width of the wide portion of the rising surface 5 almost matches the width and depth of the width inside the outer box 9 for packaging. Each rising surface 5
The folding line 7 and the cutting line 8 of the boundary form an upper boundary, and a lower boundary. The flaps integrally formed at the upper end of each of these rising surfaces 5 include a holding flap 10 which is bent inward and a fixing flap 11 which is bent outward, two of each of which are arranged in pairs. Retention flap 10
has the same lateral direction as the wide part of the upright surface 5, the fixing flap 11 has an amount of protrusion corresponding to the difference in width between the narrow part and the wide part of the upright face 5,
Its lateral dimensions are small. The retaining flap 10 is located at the upper end of the narrow portion of the rising surface 5.
The fixing flaps 11 are respectively arranged at the upper ends of the wide parts of the raised surface 5.

When the rigid paper in this developed shape is mountain-folded along the folding line 7, the fixing margin 6 is overlapped with the end surface of the rising surface 5 on the other end, and the paper is bonded with stitching wire or adhesive, a three-dimensional structure as shown in FIG. 2 is formed. This results in a cushioning material of 100%. However, before the ventilation fan 4 is attached, the bending operation is not performed on the bending line 12 at the boundary of the rising surface 5 of the holding flap 10.

That is, the cushioning material has two opposing raised surfaces 5 that are in close contact with the inner surfaces of the two width surfaces of the outer packaging box 9.
A holding flap 10 and a fixing flap 11 are attached to the upper end of a rectangular cylindrical buffer sleeve 13 formed by two opposing rising surfaces 5 that face each other with a slight gap S between them on the inner surface of the side surface of the outer box 9. It becomes a three-dimensional form with At the lower part of the buffer sleeve 13, a cutting line 8 formed at the boundary of the rising surface 5 connects the inner surface of the side surface of the outer box 9 of the two rising surfaces 5 that face the side surface of the outer box 9. Gap S that can be created
Three fixing pieces 14 will protrude. In addition, at the upper end of the buffer sleeve 13, a restraining plane is provided which abuts against the inner surface of the width surface of the outer box 9 by bending the fixing flap 11 outward against the two rising surfaces 5 from which the fixing piece 14 does not protrude. will be formed. If this type of cushioning material is placed in the outer box 9 in a specific direction, it will be held in the outer box 9 in a three-dimensional state. That is, two of the rising surfaces 5 of the cushioning material are in close contact with the inner surface of the width surface of the outer box 9, and the other rising surfaces 5
The two sides of the bottom side are fixed pieces 14, respectively.
Therefore, the upper side faces the inner surface of the side surface of the outer box 9 with a constant gap S being maintained by the fixing flap 11. Therefore, the outer box 9 and the cushioning material can be stored together,
Packing work does not take up much space and does not cause complication in the work area. Then, if the ventilation fan 4 is housed in the cushioning material housed in the outer box 9 in a three-dimensional form, and the main body portion 1 is housed in the buffer sleeve 13, and the two holding flaps 10 are folded inward, the holding flaps 10 forms a fixed surface for holding the ventilation fan that spans the width of the outer box 9, and the front structure 3 of the ventilation fan 4 is received by this fixed surface, so that the ventilation fan 4 has a buffer space with respect to the outer box 9. It settles into a stable state that maintains . Holding flap 1
In this example, since the shutter 2 protrudes from the main body portion 1 of the ventilation fan 4, the width of the protruding one of the shutters 2 is set larger than that of the other. That is, by adjusting the width of the holding flap 10, it is possible to easily accommodate a ventilation fan 4 in which the main body portion 1 has a protruding structure. Note that if at least one of the holding flaps 10 is configured to abut against the inner surface of the width surface of the outer box 9, the holding flap 10 can perform a supporting function for the outer box 9, and the buffer sleeve 13
The stability with respect to the outer box 9 can be improved.

As is clear from the above description of the embodiments, the cushioning material for packaging ventilation fans of the present invention has a fixed piece protruding from the lower part of the square cylindrical cushioning sleeve made of rigid paper to ensure a predetermined gap with respect to the outer box. , the upper end has a flat flap that is bent outward to ensure a predetermined gap with respect to the outer box, and bent inward to receive the front structure of the ventilation fan and hold it in the buffer sleeve. It is equipped with a flap that forms a fixed surface, and can be attached to the outer box independently from the ventilation fan, so it should be handled by attaching it to the outer box separately from the ventilation fan. When packing, the ventilation fan only needs to be attached to the buffer sleeve inside the outer box, and the protruding front structure of the ventilation fan can be held with a retaining flap that can be formed by bending. Because the upper and lower fixing flaps and fixing pieces support the ventilation fan, it has an excellent buffering function, and the packing work is stable because its shape is constrained by the outer box, so the work is not complicated. It also makes storage easier. Furthermore, by setting the width of the flap that forms the fixing surface, the holding position of the ventilation fan can be easily shifted to one side, making it easy to respond to changes in the structure of the ventilation fan.
