DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning package suitable for packaging irregular-shaped products, such as home electric appliances, which are not rectangular in shape.

[0002]

2. Description of the Related Art Conventionally, home appliances not having a rectangular parallelepiped shape are packaged when transporting and storing home electric appliances such as hot air heaters and humidifiers. A corrugated cardboard box having a rectangular parallelepiped internal space is used as a package for the exterior. A buffer package is interposed between the outer box and a home appliance which is a packaged object stored in the box. Such a buffer package is formed roughly in accordance with the shape of the packaged object, and is formed by combining foams such as polystyrene, polyethylene, and urethane using a mold or the like, or punching out a flat corrugated cardboard. Used by assembling.

FIG. 7 shows an example of the use of a cushioning package made of cardboard in the case where the shape of the packaged object 1 is an elliptical column.
The buffer package 2 (2 a, 2 b) is applied to both sides of the package 1 to be combined with each other to form a substantially rectangular parallelepiped shape which is easy to distribute, and shows an arrangement state immediately before storage in a cardboard box 3 for exterior use. It is a thing. Reference numeral 4 denotes a scratch-preventing sheet that wraps the packaged object 1, and reference numeral 5 denotes a bottom spacer that enters the bottom of the cardboard box 3.

[0004]

However, since the cushioning package made of foam material is three-dimensional and bulky, it requires a lot of space for transportation and storage. Further, the buffer package is necessary from the viewpoint of physical distribution and sales, but is unnecessary when the product is used. If it is bulky, there is a problem in disposal. Therefore, recently, a cushioning package made of cardboard, which can be easily developed in a plane, is often used.

However, since the cardboard cushioning package does not have a restoring force after shock deformation and does not have a shock absorbing force as compared with a foaming material made of foam, it is necessary to form a three-dimensional structure with a space inside by assembling. There is. Also, a large area of corrugated cardboard is required, and an increase in the amount of assembly work at the time of packaging poses a problem in terms of cost. Furthermore, the handleability of unnecessary cardboard at the time of resource recovery is poor, and there is a problem in disposal.

The present invention has been made in view of such conventional problems, and has good handleability when not in use.
To provide a shock-absorbing package that can cope with a slight change in the shape of the package, facilitates the packaging operation, ensures excellent impact resistance and distribution quality, is easy to dispose of, and is suitable for environmental protection. Aim.

[0007]

In order to achieve the above-mentioned object, in the cushioning package according to the present invention, the cushioning package is interposed between an outer box having a rectangular parallelepiped internal space and a package housed in the outer box. For this reason, a part of the superposed sheets is adhered to each other to form a seal portion, and the laminate is provided with an air storage space therein.

Then, sheets having different lengths are used for the laminate. In addition, the seal portion is formed by bonding the opposite edges of the stacked sheets together to form an air storage space, and an opposing portion of the sheet in an area surrounded by the edge seal portion. A sealing portion for partitioning the air storage space by adhering them to each other is formed, and the longer sheet forming each of the divided air storage spaces is provided with a bent portion for expansion. In addition, an air filling port is provided near the edge seal portion, and air is filled in each of the air storage spaces separated from the outside.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a cross-sectional view showing a packaging state in which a buffer package to which the present invention is applied is used as a packaged object, FIG. 2 is a perspective view showing an expanded state of the buffer package, and FIG. 3 is a cross-sectional view of the buffer package. It is. When transporting or storing irregular-shaped products such as humidifiers, use a cardboard box having a rectangular parallelepiped internal space as an outer box, and interpose it with a packaged object such as a humidifier stored in the outer box, As shown in FIG. 2, a buffer package 6 whose rectangular shape is expanded is used. The cushioning package 6 is a laminate in which two sheets are overlapped, a part of the two sheets is adhered to each other to form a seal portion, and an air storage space is provided inside.

Therefore, one side of a slightly longer length L substantially equal to the height of the packaged object and one side of the packaged material as the base sheet 7 disposed outside when the laminate forming the buffer package 6 is packed. A rectangular sheet having one side of a slightly longer length S that can be wound once around the outer periphery is used. The thickness and material of the base sheet 7 are appropriately selected in order to maintain the required distribution quality of the packaged body. However, if flexibility is required, a sheet having a total thickness of 100 μm or less is preferable. When the property is required, a plastic sheet having a total thickness of about 100 to 200 μm is preferable. As the material of the base sheet 7, a sheet having a low oxygen transmission rate, a low water vapor transmission rate, and the like, and a high burst strength, a tear strength, a tensile strength, and the like is selected. As an example, it is preferable to laminate rigid nylon with nylon, and further laminate low-density polyethylene which is strong in tearing and easy to process. But,
If the impact resistance of the packaged object is large, the air filling rate can be reduced, so that a low-cost sheet of polyethylene alone can be used.

As the inner sheet 8 disposed inside when the laminated body is wrapped, one side of a slightly longer length L substantially equal to the height of the wrapped body and a length capable of being wound around the outer circumference of the wrapped body once. A rectangular sheet having one side much longer than the length S is used. In addition, the case of arrangement | positioning is also included in winding. Since the inner sheet 8 is required to expand inward by filling with air, it is particularly required to have flexibility, and it is preferable to laminate low-density polyethylene on nylon having a total thickness of 100 μm or less. However, as in the case of the base sheet 7, the cost can be reduced.

From these two sheets 7, 8, the buffer package 6
In manufacturing, first, the loosened portions 9 (9a,... 9d) for expansion are provided at four places of the inner sheet 8 so as to be kept at substantially equal intervals along the longitudinal direction thereof. Then, these portions 9 are bent, for example, bent into a trapezoidal shape and protruded to form bent portions for expansion so as to reach the opposing longitudinal edges. The length of the subsequent one side is made equal to the length S of the corresponding side of the base sheet 7. Next, the two sheets 7 and 8 are overlapped, and the opposing edges thereof are filled with an air filling port 10 for injecting air between the two sheets 7 and 8 from outside.
Are bonded together except for the above-mentioned portions, for example, by heat bonding to form a rectangular frame-shaped edge sealing portion 11.

At this time, the width of the short edge seal portions 11 (11a, 11b) at both ends of the laminated sheets 7, 8 is wider than the width of the long edge seal portions 11 (11c, 11d). And the widened outer portion 12 (12a, 12b)
Are joined at the time of packaging to form a bonding adhesive portion for forming the buffer package 6 into a ring shape. In this way, an air storage space can be provided between the stacked sheets 7 and 8.

A sealing portion for dividing the air accommodating space into approximately four equal parts by adhering mutually opposing portions between the adjacent inflated bent portions 9 of the laminated sheets 7 and 8 in the same manner. 13 (13a, 13b, 13c). At this time, for example, two places to be adhered are provided in each of the sealing sections 13 for division, and these are used as the air passages 14 (14a, 14b). Then, air can be supplied to each air storage space 15 (15a,... 15d) divided by each seal portion 13 as shown in FIG. The inner portions 16 (16a, 16b) of the short edge seal portions 11 and the sealing portions 13 for division are respectively provided in corresponding corner portions of a pair of quadrangular portions extending in the height direction of the outer box. It is formed so that it can be arranged.

Since the buffer package 6 having such a structure is a thin flat plate, it is not bulky and a large number of sheets can be easily stacked, so that a large amount of space is not required for transportation and storage. Therefore, the handleability when not in use is good.

At the time of packaging, as shown in FIG. 4, the buffer package 6 is wound once around the outer periphery of the package 17 and the upper and lower ends of the buffer package 6 are slightly up and down from the upper and lower ends of the package 17. It is arranged to protrude. Then, the bonding bonding portions 12 at both ends of the short side of the buffer package 6 are bonded. Then
Since the buffer package 6 is easily bent at each of the sorting seal portions 13, the whole including the package 17 is a rectangular parallelepiped.

Therefore, the whole is stored in a cardboard box having a rectangular parallelepiped internal space, and the air filling port 1 of the buffer package 6 is provided.
Air is injected into the internal space from zero. At this time, as shown in FIG. 1, the base sheet 7 does not expand outward because the inner wall of the cardboard box 18 exists immediately outside the buffer package 6.
However, if one side of the inner sheet 8 of the buffer package 6 is made much longer than the corresponding side of the base sheet 7 to allow slack in the portion of the inner sheet 8 forming each of the divided air storage spaces 15, Each part 9 swells inward.

By filling the required amount of air, the inner sheet 8 is brought into contact with almost the entire surface including the outer peripheral surface and the upper and lower edges of the packaged body 17 to the inside of the recess formed on the surface. Then, air pressure is applied to the packaged object 17 from the surrounding multiple directions in the directions of the arrows, so that a good supporting force can be given. Therefore, it is easy to cope with a slight change in the shape of the packaged body 17.

In particular, when the bent portions 9 for inflation are provided in the portions of the inner sheet 8 forming the divided air storage spaces 15 respectively, the amount of inflation is increased by increasing the length of the bend. be able to. If the amount of air is changed, the amount of expansion of each of the divided air storage spaces 15 can be easily selected, and the shape of the packaged body 17 can be more easily changed. After filling an appropriate amount of air, the air filling port 10 is closed, the lid of the cardboard box 18 is closed, and the packaging operation is completed. Therefore, the packaging operation is simple.

When the package 17 is wrapped with the buffer package 6 in this manner, good support force can be given to the package 17 by utilizing the air pressure acting from multiple directions around the package 17. In addition, excellent impact resistance can be exhibited during transportation and the like, and good distribution quality can be ensured. When removing the package after transportation, etc., the cardboard box 18 is opened, and a hole is made in the inner sheet 8 of the buffer package 6 using a sharp object such as a screwdriver. Then, by selecting the position and number of holes, the air filled in each of the divided air storage spaces 15 can be rapidly discharged to the outside, and the bulge of the inner sheet 8 is depressed.

Therefore, the buffer package 6 is easily taken out together with the package 17 and the buffer package 6 is further removed from the package 17.
Easy to remove from. Moreover, the cushioning package 6 can be easily collapsed into a two-folded flat plate once the air is released.
Therefore, the handling property at the time of resource recovery is improved, and it is easy to dispose, and it is suitable for environmental conservation.

In the above-described embodiment, a part 16 of the edge seal portion 11 and each of the segment seal portions 13 can be arranged in a corresponding one of the pair of four corner portions extending in the height direction of the cardboard box 18. However, as shown in FIG. 5, opposing portions of the base sheet 7 and the inner sheet 8 in the region surrounded by the edge seal portion 11 and the division seal portion 13 are bonded to each other. , Forming a division sealing portion 19 (19a, ... 19d) for further dividing each of the divided air storage spaces 15,
A part of each of the partitioning seal portions 19 is made a non-adhered portion, and each of the divided air storage spaces 20 (20a, 20a,
.. 20h) may be an air passage (not shown) for supplying air.

At this time, a loosened portion 21 (2) for inflation is formed in a portion of the inner sheet 8 forming each of the divided air storage spaces 20.
1a,... 21h) are provided, each of which is formed into a trapezoidal bent portion for expansion to reach the opposing longitudinal edge seal portions 11 respectively. In FIG. 5, each of the divided air storage spaces 15 has one vertical space.
Although the case where the sorting seal portion 19 is provided for each book is illustrated,
Further, the number of sorting seal portions may be increased, or the sorting seal portions may be provided in the lateral direction.

When each of the air storage spaces 15 thus divided is further divided by the sealing member 19 for division, the number of connecting portions of the inner sheet 8 with the base sheet 7 increases. Therefore,
As shown in FIG. 6, when each of the air storage spaces 20 divided by filling with air is inflated, the support force by the air pressure applied from multiple directions around the packaged object 17 stably acts. Therefore, even if an impact is applied during transportation or the like, the positional fluctuation of the packaged object 17 in the cardboard box is reduced, the impact resistance can be further exhibited, and the distribution quality can be maintained in a good state.

In the above embodiment, when the winding axis of the buffer package 6 with respect to the package 17 is vertical, the base sheet 7 has one side having a length substantially equal to the height of the package 17. A rectangular sheet having a length of one side that can be wound around the outer periphery of the wrapped object 17 by one turn is used, and one side of a length substantially equal to the height of the wrapped object 17 and the Although a rectangular sheet having a side longer than the length that can be wound around the outer periphery by one turn is used, when the winding axis of the buffer package with respect to the package is horizontal, the base sheet is used as the base sheet. One side of the length approximately equal to the width and the outer circumference of the
Using a long sheet with one side that can be wound around,
As the inner sheet, a rectangular sheet having one side substantially equal to the width of the object to be packaged and one side longer than a length capable of being wound once around the outer periphery of the object to be packaged is used.
