Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a ventilation fan packaging box for packaging a ventilation fan, which has a front cover at the front end of a cylindrical frame portion.

[Conventional technology]

Conventionally, ventilation fans that have a front cover that protrudes outward beyond the frame at the front end of a cylindrical frame are packed with rigid paper such as corrugated paper or cardboard, or foamed resin so that the ventilation fan is pushed in from the side. Attach a shock absorbing material such as
The entire cushioning material is packed into an outer box made of cardboard or other material. There are various types of buffer members, but the most widely used type is one made by folding rigid paper and assembling it into a three-dimensional structure. but,
In any case, conventionally, the outer case and the shock absorbing member have been separated, and have been manufactured and handled separately. Therefore, packaging work is complicated and difficult to fully automate, and when automation (mechanization) is attempted, the equipment becomes extremely complex and troubles often occur. Furthermore, in storage and handling of packaging materials, there are many disadvantages, such as the need for a large space and the need to be careful about the number of packing materials, since the outer box and cushioning member are separate.

[Summary of the idea]

The present invention was made with the aim of solving the problems and inconveniences of the conventional methods described above.It integrates the box for packing the ventilation fan and the cushioning member that cushions the ventilation fan into a single unit, making it easy to use. The purpose of the present invention is to provide a ventilation fan packaging box that can be put into a packaging state by operation, is easily compatible with packaging automation, and is easy to handle and store.

[Example of idea]

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

Packaging box 1 as an application example of the present invention shown in the drawing
is a well-known fan having a front cover (a structure on the suction side of a ventilation fan, also called an oil pan) 3 at the front end of a rectangular cylindrical frame part 2 that protrudes more radially than the frame part 2. This product is used for packaging the ventilation fan 4 of the type shown in Figure 4.The feature is that the box in which the ventilation fan 4 is packed and the buffer member that stabilizes the ventilation fan 4 and performs the buffering function within this box are combined and become a single unit. be. That is, the packaging box 1 is composed of a sheet 5 made of a rigid paper such as corrugated paper or cardboard, which constitutes the box, and a pair of sheet-shaped buffer members 6 made of rigid paper coupled to the sheet 5. The sheet 5 has ruled lines 10 for bending four lid flaps 8 that make up the lid surface and four bottom forming surfaces 9 that make up the bottom surface on four continuous side surface forming surfaces 7 that make up the circumferential side of the box. In addition, the side surface forming surface 7
A glue allowance 11 is continuously provided on the outermost surface of the
It is the unfolded form of the box itself, consisting of ruled lines 10 and notches 12, and all ruled lines 10 shown in FIG.
By folding it in a mountain shape and gluing the glue margin 11 to the opposite side forming surface 7, it becomes a rectangular box with a lid and a bottom. However, the sheet 5 does not necessarily have to have a lid surface composed of four lid flaps 8 and a bottom surface composed of four bottom forming surfaces 9 as shown in the figure, and the bottom forming surfaces 9 are at least facing each other. It is fine if it has two sheets.

The buffer member 6 includes a concave cover receiving surface 13 that receives the back surface of the front cover 3 of the ventilation fan 4 and
Cover receiving surface 13 that receives the rear end of the frame portion 2 of
It has a structure in which convex end receiving surfaces 14 parallel to the frame portion 2 are connected vertically in a stepped manner by a rising surface 15 that holds one side of the frame portion 2, and has an expanded shape as shown in FIG. It is made up of a piece of rigid paper. The buffer member 6 has support portions 16 on both sides of the rising surface 15 that vertically connect the convex portions on both sides of the cover receiving surface 13 and the concave portions on both sides of the end portion receiving surface 14, and the overall unfolded form is as described above. Two vertical slits 1 are formed in a rectangular shape with a width approximately equal to the width of the side surface 7 of the sheet 5.
7, and six bending lines 18, all horizontal.
and has. Note that among the ruled lines 18, those indicated by dotted lines in the figure are not mountain folds but valley folds. Then, as shown in FIG. 1 in the developed state of the buffer member 6, each end receiving surface 14 is adhered to the bottom surface forming surface 9 formed on the opposing side surface forming surface 7 of the sheet 5. By arranging each cover receiving surface 13 along the inside of each side forming surface 7, the unfolded form of the packaging box 1 can be obtained. However, the convex portion of the end receiving surface 14 and the side surface forming surface 7
The sheet 5 and each buffer member 6 must be adhered to the end face of the cover receiving surface 13 at a distance corresponding to the width of the concave portion of the cover receiving surface 13.

The packaging box 1 constructed in this way can be constructed by folding the combination of the sheet 5 and the buffer member 6 in the same way as to make a box, and the buffer member 6 will be three-dimensionally configured inside, and the ventilation fan 4 will be housed therein. The parts will form on their own. That is, sheet 5
After the box is bent and formed into a box, the ventilation fan 4 is placed from above between two opposing buffer members 6 formed inside, and the whole is bound with a tape, belt, etc., and the packaging is completed. The work of constructing the packaging box 1 from the unfolded packaging box 1 is similar to the box-making work by simple bending and gluing, and can also be done manually.
Or even if it is done by machine, it is simple and there are no problems. Therefore, not only is it possible to automatically pack the ventilation fan 4 using a device with a relatively simple and trouble-free mechanism, but the main materials for packaging can be handled as a single unit, so no space is required for storage. . Further, there is no need to pay attention to the quantity of packaging materials, and it is possible to plan for overall cost reduction and simplification of packaging work.

[Effect of idea]

As is clear from the above description of the embodiments, the ventilation fan packaging box of the present invention includes a box for packing a ventilation fan,
The cushioning member that buffers the ventilation fan inside the box is combined into a single unit in the unfolded form, and the box body has a cushioning function based on the simple bending operation in normal box manufacturing work. Therefore, it is possible to eliminate the steps of assembling and attaching the buffer member in the packing operation, and the packing operation can be made extremely simple. Therefore, even when it comes to automation, the mechanism of the device can be simplified with fewer troubles. Furthermore, it is easy to store and handle because it can be handled as a single unit, and overall packaging costs can be significantly reduced.
