Description

[Detailed description of the invention] This invention is a cushioning material for ventilation fan packaging that is inserted between the packaging box and the ventilation fan to secure the ventilation fan inside the packaging box when the ventilation fan is packed in a packaging box. It is related to.

As this type of cushioning material, there is one shown in FIG. 1 that has already been proposed by the applicant. What is indicated by B in the figure is the buffer material.

In the same cushioning material B, 1 is a first bottom plate part 2 provided at the center in the longitudinal direction; , 3 is a pair of upper plate portions that are defined by second folding lines b, b that are parallel to each other, and 4, 4 are a pair of upper plate portions that are defined by third folding lines (c, c) that are parallel to each other. The raised inner plate parts 5, 5 are a pair of second bottom plate parts which are defined by fourth bending lines d, d which are parallel to each other.

Reference numerals 6 and 6 indicate cut portions cut in a U-shape from the fourth bending lines d and d to the upper plate portions 2 and 2. As shown in FIG. 2, this is cut into a shape that can form a recess H into which the frame _f1 of the ventilation fan F can be fitted when the cushioning material B is assembled (described later).

Reference numerals 5a and 5a are tongue pieces that are left by cutting out a portion of the cut-and-raised portion cut and raised at the cut-out portion 6, and form a part of the second bottom plate portions 5, 5. The length of the remaining tongue portions 5a, 5a ₆
In this example, the assembled cushioning material (second
The distance between the raised outer plate parts 2, 2 and the raised inner plate parts 4, 4, which are parallel to each other, is set to be equivalent to the distance L shown in FIG.

The width w of the cushioning material B and its longitudinal dimension, that is, the first bottom plate portions 1, 1, the rising outer plate portions 2, 2,
Upper plate parts 3, 3, rising inner plate parts 4, 4 and second
Lengths 1, ₂ , ₃ , ₄ of the bottom plate parts 5, 5 and
The dimensions of ₅ are determined according to the size and shape of the packaging box C, which will be described later.
Assemble the cushioning material shown in the figure and place it in the recess H of the ventilation fan F.
When fitting the frame part f ₁ of the ventilation fan F and inserting it into the packaging box C, as shown in Figure 3, there is a gap large enough to insert another cushioning material P between the fan part f ₂ of the ventilation fan F and the packaging box C. The dimensions have been determined so that it can be stored without any gaps, leaving the g.

Since it has such a configuration, when assembling this cushioning material B, the following procedure is used. That is, in FIGS. 1 and 2, the raised outer plate parts 2, 2 are formed along the first bending lines a, a, and the upper plate parts 3, 3 are formed along the second bent lines b, b, and the raised inner plate parts 4, 4 are sequentially bent inward at a substantially right angle along third bending lines c, c, and the final second bottom plate portions 5, 5 are
It is bent at a substantially right angle to the opposite side, that is, to the outside, along the fourth bending lines d and d, and is overlapped with the first bottom plate portion 1, and attached thereto with an adhesive.

When pasting, the ends of the tongue portions 5a, 5a of the second bottom plate portions 5, 5 are brought into contact with the inner surfaces of the raised outer plate portions 2, 2. By simply bringing them into contact, the second bottom plate parts 5, 5 are easily positioned, and the raised outer plate parts 2, 2 and the raised inner plate parts 4, 4 are raised in parallel.

In the assembled cushioning material (Fig. 2) assembled in this way, the cushioning material B is
Since it is bent at almost right angles at b, b, c, c, d, and d, it is formed into a rectangular tube-like sleeve, but in reality, it is a recess formed by the notches 6, 6. This is a buffer box equipped with H and a hollow buffer wall. The recessed portion H becomes a fitting portion into which the frame portion f ₂ of the ventilation fan F just fits, as will be described later.

Figure 3 shows the ventilator F being assembled and stored in the packaging box C using cushioning material. The procedure is to first assemble the cushioning material and the ventilation fan F by inserting the frame part f ₁ of the latter F into the recessed part H of the former and fitting them together, and once they are integrated, insert them into the packaging box C, and then insert the fan part f ₂ of the ventilation fan F. Insert another cushioning material P into the gap g formed between the packaging box C and the packing box C. After inserting, close the lid of packaging box C.
Just close and seal C ₁ .

However, even if the cushioning material B is assembled and used as an assembled cushioning material as shown in FIG.
It is in a state where it is simply bent at b, b, c, c, d, and d. For this reason, it is not possible to maintain the desired right angle or an angle close to it at each bending line, and the sheet elastically stretches and attempts to return to its original shape before bending. As a result, there was a drawback in that it deformed in various ways due to the difference in restoring force at each bending point.

Due to such deformation, it may not work when assembling the frame part _f1 of the ventilation fan F and trying to fit it into the recessed part H of the cushioning material (Fig. 2).
Even after fitting, it may not be possible to insert it smoothly when storing it in the packaging box C, and the problem remains that the packaging work is generally difficult.

This idea was made in order to improve the above-mentioned problems, and it is possible to bend the standing inner plate parts 4, 4 of the cushioning material B, which has already been proposed, along the bending line in the longitudinal direction. An object of the present invention is to provide a cushioning material for packing a ventilation fan, which can be assembled into a cushioning material with good shape retention by providing a flap.

An embodiment of this invention will be described below with reference to FIGS. 4 to 6. The same or equivalent parts as in FIGS. 1 to 3 are given the same reference numerals, and their explanations will be omitted. Note that FIG. 4 corresponds to FIG. 1, FIG. 5 corresponds to FIG. 2, and FIG. 6 corresponds to FIG. 3.

In FIG. 4, B ₁ is a buffer material. In the same cushioning material B ₁ , 7, 7 are the fourth bending lines d, d
This is an Ω-shaped cut line extending from the upper plate portions 3, 3, and is provided in accordance with the shape of the frame _f1 of the ventilation fan F, which will be described later, in order to fit therein. 8, 8 is made so that it can be bent at a pair of parallel fifth bending lines e, e provided in the longitudinal direction of the upright inner plate parts 4, 4 when cutting the above-mentioned score lines 7, 7. This is the flap left on the raised inner plate portions 4 and 4.

The flaps 8, 8 are formed into elongated plate shapes, and their length corresponds to the inner surface distance between the first bottom plate parts 1, 1 and the upper plate parts 3, 3 in the assembled cushioning material shown in FIG. 4, which will be described later. It is set as.

Next, the procedure for assembling this cushioning material _B1 is as follows.
This is almost the same as the case of cushioning material B in FIG. However, before bending the second bottom plate parts 5, 5,
The only difference is that the flaps 8, 8 are bent at the fifth bending lines e, e.

When folding the flaps 8, 8, as shown in FIG.
Hold the end of the lid to prevent it from opening.

In this way, even if the assembled cushioning material tries to deform by opening or closing the bending angles at each bending line a, a, b, b, c, c, d, d, the flaps 8, 8 will become a kind of web. It functions as a rubber band, does not deform easily, and therefore has good shape retention. FIG. 5 shows the assembled cushioning material.

The procedure for storing the ventilation fan F in the packaging box C is the same as that described above (FIGS. 2 and 3). but,
In the case of the assembled cushioning material of the example, the shape retention is improved as described above, so the frame part f ₁ of the ventilation fan F
can be easily fitted into the recess H of the assembled cushioning material, and the assembled cushioning material containing the ventilation fan F can also be smoothly inserted into the packaging box C, thus making it easier to store. FIG. 6 shows the state in which the ventilation fan is housed in this manner.

As explained above, this invention has a structure in which the flap provided on the upright inner panel functions as a web for the assembled cushioning material, which improves the shape retention of the assembled cushioning material and simplifies the packing work of the ventilation fan. This has the effect of making it easier to do.
