[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an excellent shock-absorbing package used for transport packaging.
[0002]
[Prior art]
Conventionally, shock absorbers made of foamed plastics have been used as shock absorbers in logistics such as home appliances, personal computers, and precision machinery products. Today, paper cushioning materials are used instead of foamed plastics, which increase the environmental impact. Cases are increasing.
Moreover, the proposal which uses a flexible film as a buffer material conventionally is made | formed. FIG. 5 is an explanatory view of an impact-absorbing package that sandwiches an object to be packaged between flexible films proposed in Japanese Utility Model Publication No. 48-112780. As shown in FIG. 5 (a), this shock-absorbing package is formed by folding two mounts 10 'having a window frame M into an outer box, and then forming a flexible film F as shown in FIG. 5 (b). In this case, the object to be packaged H is suspended in the outer box by the two opposing flexible films F that are preliminarily pasted on the entire mount 10 '.
Further, although not shown, in Japanese Laid-Open Patent Publication No. 8-183564, a rigid bowl with a pair of flanges or a flexible film attached to the opening of a tray is made to face. A packaging body has been proposed in which an object to be packaged H is sandwiched between opposing flexible films.
[0003]
[Problems to be solved by the invention]
Paper cushioning materials are preferred in that they are easy to dispose of by incineration, but there is a problem that setting takes time and a significant cushioning effect cannot be expected.
In addition, there is a problem that the volume of the waste when it is discarded is large, and it takes time and effort, and further, paper dust from the paper enters the product and is scattered around when it is unpacked.
The packaging body that sandwiches an object to be packaged with a flexible film proposed in Japanese Utility Model Publication No. 48-1212780 almost clears the above-mentioned problem, but has a structure that holds two flexible films. Therefore, there is a problem that it cannot be used for a heavy packaged article H. In addition, there is no consideration for processing after use.
Since a packaged body that sandwiches an object to be packaged by a flexible film proposed in Japanese Patent Application Laid-Open No. 8-183564 uses a hard bowl or tray molded with plastic, processing after use is a problem. .
The present invention has been made in view of the above-mentioned problems. The structure for holding two flexible films is strengthened so that it can be applied to heavy products and is compact when not in use. An object of the present invention is to provide an impact-absorbing package that can be folded into two.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the shock-absorbing package according to the present invention has two middle frames each having four sides made of a quadrangular prism, inscribed in an outer box and vertically opposed to each other. The first inner plate, the first top plate, the outer plate, the bottom plate, the second inner plate, and the second top plate in this order from the outer side to the inner side in the direction orthogonal to the four sides of the rectangular blank through the fold line A quadrangular columnar component composed of six connected surfaces is folded so that the first inner plate is the innermost layer, and an insertion piece connected to the second top plate is connected to the first top plate and the The adjacent quadrangular prisms that are formed by being inserted into the slits between the outer plates are connected to each other at both ends of the bottom plate via oblique fold lines, and each of the bottom plates facing the inner frame is flexible. The four sides of the film piece are strongly bonded, and the object to be packaged is suspended by the two opposing flexible film pieces. Is made of the configuration are sandwiched state. Furthermore, the impact-absorbing package according to the present invention is configured so that the blank is 1/8 of the blank by the oblique fold line and two fold lines that are perpendicular to the center of the quadrangular columnar component. It consists of the structure which folds into an area.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in more detail with reference to the drawings.
FIG. 1 is a blank explanatory view of the inner frame of the shock absorbing package according to the present invention.
Fig.1 (a) is an expanded view of the blank of the inner frame of the shock absorbing package according to the present invention. As shown in FIG. 1 (a), the blank 10 is formed by punching the four corners and the center of a square paperboard or cardboard, and is composed of four quadrangular columnar components A indicated by oblique lines. The both ends of the bottom plate 4 are connected via an oblique folding line g.
Each quadrangular prism component A is a fold line a in the order of the first inner plate 1, the first top plate 2, the outer plate 3, the bottom plate 4, the second inner plate 5, and the second top plate 6 from the outside toward the inside. To the second top plate 6, the insertion piece 7 is extended, and a slit 8 is provided on the folding line b between the first top plate 2 and the outer plate 3. .
In addition, a flexible film piece F indicated by a square halftone dot is strongly bonded to the center portion of the blank 10 at the four sides of the bottom plate 3 and the flexible film film piece F.
Further, the blank 10 is provided with a fold line f crossing each other across the center of the four quadrangular columnar components A.
Therefore, the blank 10 can be folded into a size of about 1/8 in area as shown in FIG. 1B by the fold line f and the fold line g connecting the bottom plate 3.
[0006]
FIG. 2 is an assembly explanatory view of the inner frame of the shock absorbing package according to the present invention.
As shown in FIG. 2, the four quadrangular columnar components A are each folded so that the first inner plate 1 becomes the innermost layer, and finally the insertion piece 7 is inserted into the slit 8, The middle frame 20 made of the quadrangular prism body K can be assembled. Here, the inner side and the top side (upper part in FIG. 2) of each quadratic prism body K in the middle frame 20 are defined by the first inner plate 1, the second inner plate 5, the first top plate 2, and the second top plate 6. It has a double structure. The pattern is also shown in FIG.
The assembled quadrangular prism bodies K are connected to each other at both ends of the bottom plate 4 via a broken line g. Moreover, since the flexible film piece F is affixed on the periphery of the bottom plate 4, one surface of the assembled middle frame 20 is in a state of being covered with the flexible film.
Assemble the other inner frame 20 in exactly the same manner.
[0007]
FIG. 3 is an assembly completion diagram and a function explanatory diagram of the shock absorbing package according to the present invention. The two middle frames 20 assembled as described above are inserted into the outer box 30 so that the flexible film pieces F face each other, and the packaged object H is sandwiched between the two flexible films F. Is incorporated so that it can be suspended. The procedure is to place one inner frame 20 on the bottom of the outer box 30 with the top surface opened, with the flexible film side up, and then place the package H on the flexible film from the top. What is necessary is just to block the top | upper surface of the outer case 30 by pushing in the other inner frame 20 with a flexible film surface down. In FIG. 3, it is drawn vertically symmetrical, but as long as the middle frame 20 with exactly the same specifications is used up and down, the lower flexible film is pulled more by the weight of the package H. As a result, the elongation increases.
In addition, the shock absorbing package 40 according to the present invention is a flexible film so that the suspended state of the packaged item H can be maintained in the outer box 30 regardless of whether it is turned upside down or in any direction. The elongation, tensile strength, and distance between the first two flexible films must be controlled according to the size, shape, and weight of the package H.
In general, the flexible film F has a slight adhesiveness, and this exhibits a suitable action to hold the package H firmly. In addition, since the flexible film has excellent puncture strength, the packaged object H that is angular can be handled.
[0008]
FIG. 4 is a blank development view showing one embodiment of an outer box blank used for the shock absorbing package according to the present invention.
In the case of this embodiment, the blank shown in FIGS. 4A and 4B is bonded to the margin N1 and the facing surface N1 ′, and the glue margin N2 and the facing surface N2 ′, so that one blank is attached. Although it is an outer box, an auto bottom system and a lock assembly system are adopted in order to facilitate assembly and to take out the packaged item H easily. Further, like the blank 10 in the middle frame, fold lines h and i are newly added so that they can be folded as compactly as possible. The outer box 30 used for the shock-absorbing package 40 according to the present invention can withstand the total load of the package H and the two middle frames 20, and the package H is suspended by two flexible films. Any type of outer box 30 may be used as long as the inner frame 20 can overcome the stress acting to push up the top or bottom plate of the cardboard.
As the material of the outer box 30, paperboard and E flute corrugated cardboard are sufficient when the packaged item H is small, and when the size increases and the weight increases, the use of A, B flute corrugated cardboard or the like becomes necessary.
[0009]
For the flexible film F used in the shock absorbing package 40 according to the present invention, a stretch film for heavy objects such as polyolefin resin and vinyl chloride resin used in a general stretch physical distribution system can be used. Among these, polyurethane resins are excellent in extensibility, resilience, tensile strength, tear strength, puncture strength, wear resistance, etc., and are lightly tacky. It can be suitably used as an adhesive film.
[0010]
The shock-absorbing package 40 according to the present invention exhibits a strong buffering function compared to conventional cushioning materials, and is therefore ideal for transporting and packing electronic equipment, precision machinery, glass / ceramic products, etc. that are easily damaged by impact. is there.
In addition, since a transparent flexible film is used, it is possible to display in a state where the contents are shown depending on the design of the outer box, and unlike the cushioning material with a shape unique to conventional products. Any product that fits within the specified range in size, weight, and shape can be used regardless of the product item, so it can be used as a general-purpose shock-absorbing packaging material that is used by plates, courier companies, etc. it can.
Moreover, it can be used suitably also when packing various goods or components simultaneously.
Since both the outer box and the inner frame are set to be foldable, handling after use is convenient as described above.
[0011]
【The invention's effect】
According to the present invention, the flexible film piece F is bonded to the opposing surfaces of a pair of middle frames that are inscribed in the outer box 30 and each of which is composed of a quadrangular prism body K on four sides, and the packaged object H is sandwiched therebetween. By suspending it in the middle, it is possible to protect even the heavy packaged goods H from impacts in the physical distribution process, enabling general use across different products, and products with different items Can also be used when assembling as a set. In addition, by making the inner frame 20 and the outer box 30 foldable after use, it is useful for space saving and can be stored in each home and reused for repairs, etc. Volume reduction is possible.
Furthermore, the two inner frames 20 and the one outer box 30 constituting the shock absorbing package 40 according to the present invention are both folded and reduced to a compact state after use, and stored as a set. It can be reused when the packaged item H fails and is delivered to the manufacturer.
Furthermore, when discarding, volume reduction can be achieved by folding the inner frame 20 and the outer box 30.
