Description

[Detailed description of the invention] This invention relates to a cardboard holder for packaging items having protrusions such as ventilation fans.

FIG. 1 is a front view showing the inserted state of a conventional cardboard holder. In the figure, 1 is a ventilation fan as an object to be packaged, 2 is a convex portion of this ventilation fan, 3 is an outer box for packaging the ventilation fan 1, and 4 is a cardboard holder that holds the ventilation fan 1 in this outer box, and a side plate 4 is provided facing the side wall of the ventilation fan 1 so as to be in contact with the side wall of the ventilation fan 1.
a and the side plate 4 so that the tip abuts on the outer box 3.
Flap 4b bent outward from the top of a
, a bottom plate 4c that connects the lower part of the side plate 4a, and a spacer 4d that connects the flap 4b and the bottom plate 4c so as to maintain a distance between the front and rear walls of the ventilation fan 1 and the outer box 3. Reference numeral 5 denotes a pad for protecting the convex portion 2, which is adhered to the side plate 4a and bottom plate 4c of the cardboard holder 4 so as to maintain a space between it and the outer box 3.

The conventional cardboard packaging holder is constructed as described above, and therefore has the disadvantage that it requires a separate pad 5 and an adhesive process.

This idea was made in order to eliminate the drawbacks of the conventional products as mentioned above.By using the material of the cardboard holder and providing the legs, there is no need for a protective pad, and the packaging can reduce the amount of cardboard used. The purpose is to provide a cardboard holder for.

FIG. 2 is a perspective view showing a cardboard holder according to an embodiment of the invention, and FIG. 3 is a developed view thereof. In the figures, the same reference numerals as in FIG. 1 indicate the same or corresponding parts. 4e is a support plate bridging in parallel between both sides of the lower part of the side plate 4a so as to support the ventilation fan 1; 4f extends downward from the lower part of the side plate 4a between the support plates, and its tip abuts on the bottom of the outer box 3; It is the leg. The spacer 4d extends inward from both ends of the flap 4b, is bent downward, reaches the support plate 4e, and communicates with the support plate 4e in a bridge-like manner on the same plane. In Figure 3, 6 is the notch, 7 is the crease line,
8 is a cutout.

The cardboard holder configured as above is
From the state shown in FIG. 3, the crease line 7 is bent to form the shape shown in FIG. 2, and packaging is carried out in the same manner as in FIG. 1.
That is, the cardboard holder 4 is inserted into the outer box 3, the tip of the flap 4b is brought into contact with the side wall of the outer box 3, and the legs 4f are erected on the bottom surface. Then, the ventilation fan 1 is slid and inserted between the spacers 4d so that the side wall contacts the side plate 4a, and is supported on the support plate 4e. In this state, the ventilation fan 1 is held at a distance from the inner wall of the outer box 3, and the convex portion 2 is protected between the legs 4f.

In the above embodiment, the leg portion 4f is formed by the cutout 8, but the leg portion 4f may be folded back leaving the cutout portion and reinforced as a double wall structure. Furthermore, although the above description relates to packaging for ventilation fans, it is equally applicable to packaging for other products.

As described above, according to the present invention, since the legs are provided using the material of the cardboard holder, there is no need for protective pads and their adhesive work, and the height dimension is also reduced, which reduces the amount of cardboard used. It has the advantage of being less expensive and can be manufactured at a lower cost.
