Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a ventilation fan packaging box for separately packaging a ventilation fan having a removable front cover at the front end of a rectangular cylindrical frame portion.

[Conventional technology]

Conventionally, ventilation fans that have a front cover that protrudes outward from the frame at the front end of a rectangular cylindrical frame are packed with rigid paper such as corrugated paper or cardboard, or foam, so that the ventilation fan is pushed in from the side. A cushioning material made of resin or the like is attached, and the entire cushioning material is packed into an outer box made of cardboard or the like. 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. However, in any case, in the past,
As disclosed in Japanese Patent No. 20540, the outer case and the buffer member are separate and must be 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. In addition, when storing and handling packaging materials, the outer box and cushioning material are separate, and there are many cushioning materials, so there are many inconveniences such as requiring a large space and having to pay attention to the number of cushioning materials. .

[Summary of the idea]

The present invention was made with the aim of solving the above-mentioned conventional problems, and a shock absorbing member for cushioning the ventilation fan is integrally connected to a part of the box for packing the ventilation fan, and the whole is made into a single unit. To provide a ventilation fan packaging box that is easy to handle, easily adapts to automation, and has good handling and storage properties, in which the shock absorbing member has a structure that protects the front cover removed from the frame. It is something.

[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
, a removable front cover (a structure on the suction side of a ventilation fan, also called an oil pan) 3 is attached to the front part of a rectangular cylindrical frame part 2, which protrudes more radially than the frame part 2. It is used for packaging a ventilation fan 4 of a generally well-known type, and includes a box 5 in which the ventilation fan 4 is packed, and a one-to-one set of buffer members 6 that stabilize the ventilation fan 4 and perform a buffering function. Its unique feature is that it takes the form of a single sheet of steel paper when unfolded. That is, the packaging box 1 is obtained by adhering a pair of buffer members 6 in an expanded form to a part of a sheet constituting the box body 5 obtained by punching out a piece of rigid paper such as corrugated paper or cardboard. It is. The sheet has four lid flaps 8 that make up the lid surface and four bottom flaps 9 that make up the bottom surface on the four continuous side surface forming surfaces 7 that make up the peripheral side of the box body 5, and the four bottom flaps 9 that make up the bottom surface. Ruled line 1
0 as a boundary, and a glue allowance 11 is further provided on the outermost surface of the side surface forming surface 7, which is the development form of a rectangular box consisting of ruled lines 10 and notches 12. A rectangular box 5 with a lid and a bottom is obtained by bending all the ruled lines 10 shown by solid lines in the figure and gluing the glue margin 11 to the side surface 7 on the opposite side. However, the seat does not necessarily have a lid surface with four lid flaps 8 as shown in the illustration.
Further, it is not necessary to form the bottom surface with four bottom surface forming surfaces 9.

The pair of buffer members 6 are in contact with a rectangular frame receiving surface 13 that receives the front back of the frame portion 2 of the ventilation fan 4 from which the front cover 3 has been removed, and one side of the rectangular cylindrical frame portion 2, respectively. A vertically erected support surface 14 that holds and supports the frame receiving surface 13 almost horizontally within the box body 5; A pair of holding bands 16 having a bent part 15 in the middle part closer to the supporting surface 14 side than the ruled line 10 forming the boundary with the surface 14, and a pair of rectangular holding bands 16 connected to one free end and the frame receiving surface 13. A rectangular shape with a width dimension that approximately corresponds to the width dimension of the side surface forming surface 7, which consists of a gluing allowance 17 and a protective plate part 18 that is connected to the gluing allowance 17 and that constitutes a free end, which is connected to the gluing allowance 17 and the frame receiving surface 13. It is a flat plate. This buffer member 6 is attached to two bottom flaps 9 that face each other in the unfolded state, with a glue allowance of 1 on each free end side.
7 is connected to the sheet constituting the box body 5 by gluing each glue margin 17 on the side of the frame receiving surface 13 to the upper side of the two side surface forming surfaces 7 that are continuous with the bottom flap 9. There is. Each retaining band 16 of the buffer member 6 has a bent portion 15 that is connected to the support surface 1.
The three-dimensional buffer member 6 has a structure that protrudes inward from the ventilation fan 4, and holds two opposing sides of the frame part 2 of the ventilation fan 4 with support surfaces 14, and holds the other two sides with a holding band 16.
It is held by the inner side end surface of the bent portion 15 of. That is, the buffer member 6 in the expanded form has two cutting lines 19 running in parallel in the longitudinal direction,
It is a simple rectangle consisting of five bending lines 10 arranged in the horizontal direction, and does not include any holes or windows to be penetrated.

The packaging box 1 configured in this way has a cushioning member 6
If the combined sheets are folded in the same way as to make a normal box, a three-dimensional structure consisting of one-to-one pairs of buffer members 6 will be formed inside, facing each other.
The part that accommodates the ventilation fan 4 will naturally be formed. That is, after the sheet is bent and formed into a box 5, the frame part 2 of the ventilation fan 4 is placed from above into the space formed by the two opposing buffer members 6 formed inside, and then each buffer member is The protection plate portion 18 of the member 6 may be bent inward to overlap the front surface of the frame portion 2, and the front cover 3 may be placed on top of this.
The work of constructing the three-dimensional packaging box 1 from the unfolded packaging box 1 is similar to the box-making work by simple folding, and is a simple problem that requires special attention whether it is done by hand or by machine. There are no points. Therefore, not only is it possible to automatically pack the ventilation fan 4 using a relatively simple and trouble-free mechanical device, but the main material for packaging is a single unit and can be handled as one component, making storage easier. It is also easy to handle. In addition, there is no need to pay attention to the quantity of packaging materials, and the cushioning function is comparable, so overall it is an excellent product that can reduce costs and simplify packaging work. It can be said that there is.

[Effect of idea]

As is clear from the above description of the embodiments, the ventilation fan packaging box of the present invention has a one-to-one set of cushioning members that put the ventilation fan inside the box in a buffered state, in a part of the unfolded shape of the box in which the ventilation fan is packed. A frame receiving surface that receives the front back of the frame with the front cover of the ventilation fan removed from the buffer member, a support surface that holds the outer periphery of the frame, and a support surface that is interposed between the front cover and the front of the frame. death,
Since it consists of a protective plate part that protects the front cover, it is possible to obtain a packaging box with high binding properties and an excellent front cover protection function based on the simple bending operation in normal box manufacturing work. In addition, it is possible to eliminate troublesome processes such as assembling and mounting the buffer member in the packing operation, and the packing operation can be made extremely simple. Furthermore, with regard to packaging automation, the mechanism of the device can be made simple and less troublesome. Furthermore, it is extremely easy to store and handle as it can be handled as a single unit, and the proportion of waste materials generated during manufacturing is small, so it is possible to realize a significant reduction in packaging costs as a whole.
