Description

[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 item to be packaged between flexible films proposed in Japanese Utility Model Laid-Open No. 48-1212780. As shown in FIG. 5 (a), two mounts 10 'having a window frame M are folded into the outer box, and the window frames M are opposed to each other as shown in FIG. The packaged article H is intended to be suspended in the outer box by the two flexible films F stuck on the mount.
Although not shown, in Japanese Patent Application Laid-Open No. 8-183564, a rigid bowl having a pair of flanges or a flexible film attached to the opening of a tray is made to face. A package has been proposed in which an object to be wrapped 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]

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 out four corners and the center of a square paperboard or cardboard, and is composed of four triangular pillar components B indicated by diagonal lines, each of which is a bottom plate 3 are connected to each other through oblique fold lines e.
Each of the triangular columnar components B is arranged in the order of the first inclined plate 1, the first outer plate 2, the bottom plate 3, the second inclined plate 4, and the second outer plate 5 from the outside toward the inside through the folding lines a to d. In the first inclined plate 1, an insertion piece 6 is extended, and a slit 7 is provided in the approximate center of the second inclined plate 4.
Folding pieces 8 and 9 are connected to both ends of the first outer plate 2 in this order via folding lines g and h.
In addition, a flexible film piece F indicated by a square halftone dot is strongly bonded to the central portion of the blank 10 on 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 that crosses the center of the four triangular columnar components B and is orthogonal to the center of the blank.
Therefore, the blank 10 can be folded into a size of approximately 1/8 as shown in FIG. 1B by the fold line f and the fold line e 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 triangular prisms B are wound and folded so that the second outer plate 5 becomes the innermost layer, and finally the insertion piece 6 is inserted into the slit 7 so that the four sides are The middle frame 20 made of the triangular prism body K can be assembled. The cross-sectional shape of each triangular prism body K in the middle frame 20 assembled in this way is a right triangle as shown by the following FIG. 3, and the outer side and the inclined side are the first outer plate 2, A double structure is formed by the second outer plate 5, the first inclined plate 1, and the second inclined plate 4.
The four triangular prism bodies K assembled are connected to each other at both ends of the bottom plate 3 via a folding line e. Further, the folding pieces 8 and 9 connected to both ends of the pair of first outer plates 2 facing simultaneously with the above folding are folded by a folding line h, as shown in FIG. Is folded back to an angle of 45 ° to form a partition plate S that closes the end face of each triangular prism. The partition plate S functions as a column between the bottom plate 3 and the top plate of the outer box 20 or the bottom plate together with the double outer plates 2 and 5 of the triangular prism body K.
Since the flexible film piece F is stuck on the bottom plate 3 in the periphery thereof, one surface of the assembled middle frame 20 is closed with the flexible film.
Assemble the other inner frame 20 in exactly the same manner as above.
[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 whose top surface has been opened with the flexible film surface facing up, insert the package H from above, and place it on the flexible film. Finally, the other inner frame 20 is pushed in and the top surface of the outer box 30 is sealed. 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 has a slight adhesiveness, and this exhibits a suitable action to hold the package H firmly. Moreover, if the flexible film excellent in puncture strength is used, the to-be-packaged object H which is squared can also 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 the outer box 30 is used, an auto-bottom method and a lock assembly method are employed in order to facilitate assembly and to facilitate removal of the package H. 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 optimal for transportation and packaging of electronic devices, precision machines, glass / ceramic products, etc. that are easily broken by impact. .
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.
Further, the two inner frames 20 and the outer box 30 constituting the shock-absorbing package 40 according to the present invention are both folded into a compact state after use and stored as a set. It can be reused when it breaks down and is sent to the manufacturer.
Furthermore, when discarding, the volume can be reduced by folding the inner frame 20 and the outer box 30.
[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 the four sides are made of triangular prisms K, and the packaged object H is sandwiched therebetween. By suspending it, the heavy package H can be protected from impact during the distribution process, and can be used for various products. It can also be used when packing 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., and discarded. In some cases, the volume can be reduced.
