Embodiments will be described below with reference to the accompanying drawings. The same reference numerals in each figure indicate the same or corresponding parts. Further, in this disclosure, overlapping explanations will be simplified or omitted as appropriate. Note that the present disclosure may include all modifications and all combinations of the configurations disclosed by the following embodiments without departing from the spirit thereof.

Embodiment 1.
FIG. 1 is a perspective view schematically showing a packaging structure using a packaging device 10 according to the first embodiment. A packaging device 10 for packaging an object 1 such as a product includes an outer box, a packaging material 2 such as a cushioning material, and a band 3. The packaging structure according to the present embodiment is a structure in which an object to be packed 1 such as a product and a packaging material 2 such as an outer box and a cushioning material are bound by tightening a binding band 3.

As shown in FIG. 1, the band 3 is tightened while being wrapped around the outer periphery of the object to be packed 1 and the packaging material 2. The band 3 is hung in the vertical direction. Although FIG. 1 shows an outdoor unit of an air conditioner as an example of the product that is the object to be packed 1, the object to be packed 1 is not limited to this. Anything is fine. Further, in the example shown in FIG. 1, the packaging material 2 is provided on the upper and lower sides of the object to be packed 1, but it is sufficient if the packaging material 2 is provided on at least one of the upper and lower sides.

The packaging structure according to this embodiment is characterized by the structure of the band 3 and the way it is wrapped. FIG. 2 is a perspective view schematically showing the structure of the band 3 according to the first embodiment. As shown in FIG. 2, the band 3 according to this embodiment includes a first band portion 3a and a second band portion 3b.

The first band portion 3a is an elongated member. The first band portion 3a is made of a highly rigid and non-stretchable material, similar to a general binding band or the like. The first band portion 3a is made of, for example, a plastic material.

The second band portion 3b is a short member. The second band portion 3b is connected to the first band portion 3a. The second band portion 3b is formed from a different material from the first band portion 3a. More specifically, the second band portion 3b is formed from an elastic material having elasticity. The second band portion 3b is made of, for example, a rubber material. The band 3 according to this embodiment is characterized by including this second band portion 3b in addition to the first band portion 3a. The second band portion 3b and the first band portion 3a constitute one band 3.

3 and 4 are cross-sectional views schematically illustrating how to wrap the band 3 according to the first embodiment. The band 3 binds the object 4 including the object to be packed 1 and the packaging material 2. The band 3 is wrapped around the outer periphery of the object 4 and tightened. As shown in FIGS. 3 and 4, the band 3 is wrapped and tightened so that the second band portion 3b is located on the bottom side of the object 4. Note that FIG. 3 shows an example in which the band 3 is used for an object 4 without legs, and FIG. 4 shows an example in which the band 3 is used for an object 4 that has legs. .

In order to explain the effects of this embodiment, an example will be described in which, as a general distribution route, the object 4 is stored in a warehouse and then transported by a truck, and after being unloaded from the truck, the object 4 is dragged and moved. For example, if the packaging material 2 is deformed due to the stacking load during storage in a warehouse, at this point, the first band portion 3a or the second band portion 3b is pressed down by the weight of the object 4, so the second band portion 3b is pressed down by the weight of the object 4. The band portion 3b does not expand or contract.

Next, when the object 4 is loaded onto the truck, the object 4 is lifted up and away from the ground, and the second band portion 3b becomes elastically elastic. The second band portion 3b shrinks following the deformation of the packaging material 2. In this way, the second band portion 3b has a function of elastically contracting so as to fill the gap created between the object 4 and the band 3. In normal times when the packaging material 2 is not deformed, the second band portion 3b is in an extended state. When the packaging material 2 is dented, the second band portion 3b is elastically contracted to return to its original state so as to fill the gap caused by the dent. According to the above configuration of the present embodiment, it is possible to prevent the band 3 that binds the object to be packed 1 and the packaging material 2 from loosening.

As described above, the second band portion 3b is located on the bottom side of the object 4. For example, when dragging the object 4 after unloading it from a truck, a worker may hold the band 3 and pull it. At this time, since the second band part 3b is located on the bottom side of the object 4, the operator will pull the first band part 3a instead of the second band part 3b. In this embodiment, the second band portion 3b will not be stretched by the operator, and the workability when pulling and transporting the band 3 will not be impaired.

Note that the second band portion 3b may be sandwiched between the object 4 and the ground as shown in FIG. 3, or the second band portion 3b may be separated from the object 4 as shown in FIG. Good too. In the example of FIG. 4, the first band portion 3a is sandwiched between the object 4 and the ground in a portion continuous to the second band portion 3b. In the example shown in FIG. 4, deterioration of the second band portion 3b can be suppressed.

Embodiment 2.
Next, a second embodiment will be described. As shown in FIG. 1 in the first embodiment, the packaging device 10 according to the present embodiment also includes an outer box, a packaging material 2 such as a cushioning material, and a band 3. The packaging structure according to this embodiment is characterized by the configuration of the binding band 3. FIG. 5 is an exploded perspective view schematically showing the configuration of the binding band 5 according to the second embodiment. FIG. 6 is a perspective view schematically showing the configuration of the binding band 5 according to the second embodiment. Hereinafter, in this embodiment, the characteristics of the band 3 that binds the object 4 including the object to be packed 1 and the packaging material 2 will be described in other words as the binding band 5.

The binding band 5 is composed of one band 5a and a fixture 5b. The band 5a is a long belt-shaped member constructed in the same manner as a general binding band or the like. The fixture 5b has a loosening prevention mechanism that prevents the band 5a from loosening after being tightened.

7 and 8 are enlarged views of the area around the fixture 5b of the binding band 5 according to the second embodiment. A terminal end 5c and a starting end 5d of the band 5a are fixed through a fixture 5b. As the structure for fixing the band 5a to the fixture and the mechanism for preventing loosening of the fixture 5b, any of various conventionally known structures can be used. As an example, the fixture 5b has unevenness that prevents the band 5a from running backwards. The end face of the band 5a near the terminal end 5c is processed into a shape corresponding to the irregularities of the fixture 5b. Since the concavities and convexities of the band 5a and the fixture 5b engage with each other, the band 5a does not run backwards. Further, as an example, a structure for fixing the starting end 5d of the band 5a is provided on the back side of the fixture 5b. For example, it is fixed by passing the starting end 5d through a plurality of rollers provided on the fixture 5b.

The terminal end 5c of the band 5a is provided with a weight mechanism 6 that has the function of moving the terminal end 5c by gravity so that the band 5a is tightened. Band 5a is made of plastic material, for example. The weight mechanism 6 is made of a material having a higher weight density than the band 5a, for example, a metal material such as aluminum, iron, copper, or lead.

The effects of the packaging structure and binding band 5 of this embodiment will be explained. When the binding band 5 is tightened, the weight mechanism 6 is constantly pulled downward by gravity. In this way, the weight mechanism 6 always applies a tightening force to the band 5a. On the other hand, since there is a loosening prevention mechanism, even if a force acts in a direction that loosens the band 5a, the band 5a will not run backwards and loosen. As described above, according to the present embodiment, the weight mechanism 6 automatically applies a force in the direction of tightening the band 5a, so that, for example, if the packaging material 2 is dented during the distribution process, the band 5a will follow suit. Automatically tightened. According to the above configuration of the present embodiment, it is possible to prevent the band 5a that binds the object to be packed 1 and the packaging material 2 from loosening.

As shown above, the packaging structure according to each embodiment has a function of automatically preventing loosening of the band 3 due to the physical properties of the band 3 without any external intervention by an operator. It is something. Note that Embodiment 1 and Embodiment 2 described above can be combined. For example, the band 3 may include both the second band portion 3b that has a function of preventing loosening due to elasticity, and the weight mechanism 6 that has a function of preventing loosening due to gravity.
