Description

  The present invention relates to a packaging box having a cushioning function, and more particularly, a packaging having a cushioning function that can be used for packaging and transporting high-precision electronic devices such as personal computers and cameras, and other articles that are vulnerable to impact, and can be used repeatedly. Regarding the box.

  When transporting high-precision electronic devices such as personal computers, tablet computers, cameras, and multifunctional mobile phones, and glass products, ceramics, and other items that are vulnerable to impacts, these items are conventionally hammocked (or suspended in the air). It is widely practiced to pack and transport in a packaging box (for example, see Patent Documents 1 and 2).

  In Patent Document 1, each of a pair of upper and lower support means for supporting an object to be packaged away from the wall of the box includes an elastic sheet stretched between end parts, and the object is packaged between the two elastic sheets. In a packaging box configured to hold an object in between, a packaging box having a configuration using a two-layered or three-layered bubble buffer sheet as an elastic sheet is disclosed.

  Further, Patent Document 2 discloses a first half body having a flexible sheet-like suspension member for holding the lower side of the package between the upper ends of both side plates, and for holding the upper side of the package between the lower ends of the front and rear side plates. A packaging box configured to hold an object to be packaged in a suspended state between a suspension member and a pressing member in a packaging box that is combined with a second half having a pressing member in the form of a flexible sheet. It is disclosed.

  According to these hammock-type packaging boxes (suspension-type packaging boxes), there is no problem of damage to the package due to air leakage, as with air bag-type packaging boxes, and there is little misalignment of the packing position even during transportation. It is possible to transport an article to be wrapped that is vulnerable to impact.

  However, each of the conventional packaging boxes described above has a problem that only one packaged item can be packed in one box, and the transportation efficiency is extremely poor. Further, when the conventional packaging box is dropped, the impact due to the drop does not become a predetermined value or less (for example, 50 G or less) depending on the dropping direction, and the position of the packaged object may be shifted or damaged.

  The present invention has been made in view of the above points, and provides a packaging box having a cushioning function capable of packing a plurality of packages in one box and capable of reducing the impact when dropped in any direction to a predetermined value or less. For the purpose.

  In order to achieve the above object, the present invention is such that the bottom plate and the left and right side plates are integrally formed via a folding line, and each side plate is approximately 90 degrees with respect to the bottom plate during use. Both ends are fitted into the box body of the inner box, which is raised and opened on the top and front and rear sides, and a concave groove formed along the top edge near each top edge of each side plate By doing so, a plurality of rod-shaped horizontal support members laid in parallel to the surface of the bottom plate, and a single sheet member having a width approximately equal to the length of the horizontal support member, the center between adjacent horizontal support members A plurality of slack portions formed between the adjacent horizontal support members, each of which is bridged and fixed with the slackness between the horizontal support members so that the lowest point of the slackness is located near the portion. Hammock part and one or more of the hammock parts The outer box which covers the inner surface of the box body as a whole while closing the upper surface and both front and rear surfaces of the box body while preventing the shaking of at least the plurality of hammock parts. The sheet member has a buffering function that is corrugated to form a corrugated cross section in a direction orthogonal to the axial direction of the horizontal support member in order to provide a buffering function.

  Here, the sheet member may be a synthetic resin nonwoven fabric. Further, the plurality of hammocks are connected to each other by an annular belt as a whole of the flexible material that penetrates in the vicinity of the left and right ends, so that the packaged product is accommodated in the hammocks surrounded by the belt. It may be.

  Further, in order to achieve the above object, the present invention has a substantially rectangular flat plane portion and two arm portions formed on the left and right sides thereof, which are foldable and integrally configured. Inserted from the upper surface of the main body, the inner portions of the two arms facing each other are in contact with or close to the side surface of the outermost hammock portion of the plurality of hammock portions so that the entire plurality of hammock portions are sandwiched from both left and right sides The stopper cushioning member made of a light and thick hard board nonwoven fabric or a stretchable cushion material nonwoven fabric has a configuration in which the lower surface of the flat surface is in contact with the upper portion of the horizontal support member. It is characterized by being provided in.

  According to the present invention, a plurality of packages can be packed in one box, and the impact at the time of dropping can be reduced to a predetermined value or less in any direction.

It is a figure explaining the corrugating process with respect to the nonwoven fabric in this invention. It is a perspective view for explanation of an example of the shape at the time of transportation of the packaging box of the present invention. It is a perspective view of one embodiment of a stopper buffer member. Perspective when a stopper cushioning member is attached to the inner box of the packaging box It is a perspective view of the state which folded the stopper buffer member of FIG. 1 is a schematic perspective perspective view of Example 1. FIG. 6 is a schematic perspective view of Example 2. FIG.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a transparent perspective view of an embodiment of a packaging box having a buffering function of the present invention, and FIG. 2 is a partially enlarged perspective view of FIG. In both drawings, the same components are denoted by the same reference numerals. As shown in FIG. 1, the packaging box 10 of this embodiment is mainly comprised from the box main body A of an inner box, and the hollow rectangular parallelepiped outer box B which accommodates the box main body A. As shown in FIG. The box main body A includes a bottom plate 11 and left and right side plates 12 and 13 that are integrally provided on both side edges of the bottom plate 11 so as to be bent. The material of the bottom plate 11 and the side plates 12 and 13 may be made of paper or plastic, but in consideration of durability, water leakage, etc., a dump plate or a twin cone is preferably used.

  The box body A is configured integrally with the bottom plate 11 and the side plates 12 and 13 so that the side plates 12 and 13 can be raised at about 90 degrees with respect to the bottom plate 11 via the folding lines 14 and 15. Has been. In the vicinity of the upper edge of the inner surfaces of the side plates 12 and 13, recessed grooves 16 are formed so as to face each other along the upper edge. When the box body A is transported in a state of containing a packaged product (that is, in use), the side plates 12 and 13 are approximately 90 relative to the bottom plate 11 via the folding lines 14 and 15 as shown in FIG. The upper surface (front surface) and both front and rear surfaces of the box body A are closed by being accommodated in the outer box B, and the overall shape is a rectangular parallelepiped box. A body packaging box 10 is formed.

  A plurality of (7 in the example of FIG. 1) bar-like horizontal support members 17 are bridged between the concave grooves 16 formed in the side plates 12 and 13 in parallel to the bottom plate 11 and spaced apart from each other. Has been. The horizontal support member 17 is formed with convex portions at both end portions, and the convex portions are respectively fitted in the concave grooves 16. In addition, the horizontal support members 17 have both end portions in the recessed grooves 16 so that the distance between the adjacent horizontal support members can be finely adjusted according to the package to be transported. It is arranged so that it can move freely. Moreover, since the edge part of the ditch | groove 16 becomes an opening and the horizontal support member 17 is detachable through this opening edge part, the horizontal support member 17 and the box main body A can be separated.

  As shown in FIGS. 1 and 2, a hammock portion 18 is formed between the horizontal support members 17 to accommodate packages to be transported. That is, a plurality of hammock portions 18 are formed in one packaging box 10. In the hammock portion 18, for example, a single sheet-like non-woven fabric 19 having a width approximately equal to the length of the horizontal support member 17 is positioned so that the lowest point of looseness is positioned near the center between the adjacent horizontal support members 17. In addition, the horizontal support member 17 is stretched between the horizontal support members 17. The non-woven fabric 19 has, for example, three places for each horizontal support member 17 by a band 21 which is a stopper member made of plastic or the like so that the hammock portion 18 maintains a desired shape and does not shift, deform or come off during transportation. It is fixed at the position. The lowest point of the slack of the plurality of hammocks 18 is, for example, an interval of about 5 cm with respect to the bottom plate 11 (shown by d1 in FIG. 2) so as not to contact the surface of the bottom plate 11 even when the packaging box 10 is extended. ) Is set to the upper side only.

  The plurality of hammocks 18 are located at positions near the left and right ends, specifically, about 30 to 50 mm higher than the lowest point, and about 30 to 40 mm, for example, from both edges in the width direction of the hammock 18. They are connected to each other by a belt 20 made of a flexible material such as rubber or spandex that penetrates at a distance (indicated by d2 in FIG. 2). The belt 20 prevents swinging like a swing in the direction perpendicular to the axial direction X of the horizontal support member 17 (hereinafter referred to as roll) with the horizontal support member 17 generated during transportation as a fulcrum.

  At the same time, the belt 20 regulates the movement in the same direction as the axial direction X of the package 23 accommodated in the hammock portion 18 shown in FIG. It also has a side impact absorbing function that prevents the package 23 stored in the hammock portion 18 from colliding with the outer box A when falling in the same direction. The package 23 is a high-precision electronic device such as a personal computer, a tablet computer, a camera, a multi-function mobile phone, a glass product, ceramics, or other articles that are vulnerable to impact.

  For example, as shown in FIG. 1, the belt 20 is provided so as to appear at a predetermined length in the horizontal direction on the outer surface of the two outermost hammocks 18 among the plurality of hammocks 18. As described above, the ring structure has a diameter enough to allow the packaged product 23 to enter. The width of the belt 20 is, for example, about 30 to 50 mm so that the package 23 does not pop out. The belt 20 may be configured to have a length adjusting function (for example, a function of fastening a part thereof with an adhesive tape) so that the entire length can be adjusted according to the size and number of packages.

  The feature of this embodiment is that the sheet-like nonwoven fabric 19 constituting the hammock portion 18 is corrugated. This corrugating process is a processing method in which the cross section of the nonwoven fabric 19 is formed into a corrugated shape as shown in FIG. 3, and the processing method itself is known. The corrugated height h is about 2 mm, 5 mm, or 10 mm, and the corrugated pitch p is, for example, about 10 to 15 mm. Here, the forming direction in which the cross section of the nonwoven fabric 19 is corrugated is a direction orthogonal to the axial direction X of the horizontal support member 17. As the nonwoven fabric 19, for example, a synthetic resin such as polyester or polypropylene is used. Thereby, when the packaging box 10 is dropped, the hammock part 18 that accommodates the packaged product 23 expands and contracts like rubber, and the characteristic that the impact on the packaged product 23 can be greatly reduced is obtained.

As a material of the hammock portion 18, in addition to the above-described nonwoven fabric, a woven fabric, a synthetic resin sheet (including a perforated sheet), and the like are also possible. However, considering the absorbability of the impact, 50 to 400 g / m ² is preferably used although it depends on the weight of the entire packaging box 10 during transportation. The belt 20 can also be a corrugated sheet.

  In addition, by winding the sheet-like nonwoven fabric 19 constituting the hammock portion 18 also on the top surface side of the horizontal support member 17, the top surface impact when the packaging box 10 is dropped in the top surface direction can be absorbed. Is possible.

  The outer box B has a rectangular parallelepiped shape that accommodates the box body A, and may be made of paper or plastic. However, in consideration of durability, water leakage, etc., a dump plate or twin cone is preferable. Used.

  FIG. 4 is a perspective view for explaining an example of the shape of the packaging box of the present invention during transportation. When transporting, the outer box B closes the top and front and rear surfaces of the box body A of the inner box that stores the packaged product that is transported to the hammock section 18, and at least the plurality of hammock sections 18 shake. The inner box is accommodated in a state in which the box is prevented to constitute a box-shaped packaging box as a whole. At this time, the first shock absorber 101 is inserted into the gap between the top surface of the box body A and the outer side surface of the hammock portion 18, and the horizontal support member is inserted into the gap between the outer end portions of the side plates 12 and 13. The packaging box 10 is configured by inserting the second shock absorber 102 so that 17 does not shift. The first and second shock absorbers 101 and 102 are bound so as not to be displaced by, for example, an adhesive tape or a buckle.

  According to the packaging box 10 of the present embodiment, the size of one hammock portion 18 is set to one portable electronic device such as a tablet computer (for example, the size is about 241.2 mm in depth, about 185.7 mm in width, and height 13.4- When it is set to a value slightly larger than the size that can be accommodated (for example, about 7.5 mm), for example, 5 to 6 portable electronic devices can be packed at the same time in one normal size packaging box of 1 m in length, width, and height. And can be transported. Moreover, according to the packaging box 10 of this embodiment, since the nonwoven fabric 19 which comprises the hammock part 18 is corrugated and has a buffer function, it can make the impact at the time of fall below a predetermined value in any direction so that it may mention later.

  A horizontal support member in which the outer box B is folded and the box body A of the inner box and the non-woven fabric 19 are fixed by the band 21 when there is no packaged item in the packaging box 10 as after the package is delivered to the destination. 17 and the bottom plate 11 and the side plates 12 and 13 can be folded and moved in a compact configuration as a whole. In this way, the packaging box 10 can be used repeatedly as a returnable box.

  In the above description of the embodiment, the example in which the first and second shock absorbers are inserted into the gap between the inner box and the outer box B has been described. However, the operation is complicated and not efficient. Moreover, although it is also conceivable to provide a foldable claw portion as an alternative to the second shock absorber in the outer box itself, the same applies to that case. Next, a stopper cushioning member that greatly improves the working efficiency will be described.

  FIG. 5 shows a perspective view of one embodiment of the stopper cushioning member. As shown in the figure, the stopper cushioning member 30 is composed of a flat surface portion 31 having a substantially rectangular shape, and arm portions 32 and 33 formed on the left and right sides thereof, and these are integrated. . The width W of the stopper cushioning member 30 in the left-right direction of the flat surface portion 31 is set to be slightly larger than the overall width of the plurality of hammocks 18 described above. Further, the height H when the stopper cushioning member 30 is used is selected to be approximately the height from the horizontal support member 17 to the lowest point of the hammock portion 18 described above. The arms 32 and 33 are configured to be foldable. The stopper cushioning member 30 is made of a light and thick hard board nonwoven fabric or a stretch cushion nonwoven fabric, and for example, a steam jet (trade name) manufactured by Kuraray Laflex Co., Ltd. is preferably used.

  FIG. 6 shows a perspective view when the stopper cushioning member is mounted on the inner box in the packaging box of the present embodiment. In the figure, the same components as those in FIGS. 1, 2 and 5 are denoted by the same reference numerals, and the description thereof is omitted. In FIG. 6, the stopper cushioning member 30 is inserted and mounted from the top surface of the box body A of the inner box housing the packaged product in the hammock portion 18. The planar portions 31 are in contact with or close to the side surfaces of the outermost hammock portion of the plurality of hammocks 18 so that the inner portions of the arms 32 and 33 facing each other sandwich the entire hammocks 18 from both the left and right sides. Is in contact with the upper portion of the horizontal support member 17. Since the stopper cushioning member 30 is relatively hard and has cushioning properties, it is possible to prevent the hammock portion 18 from rolling over during transportation and to absorb the top surface impact during dropping.

  Since the same function as when the first and second shock absorbers are inserted can be realized at a time by a simple operation of mounting one stopper cushioning member 30, work efficiency can be greatly improved. . As shown in FIG. 5, the packaging box accommodates the inner box to which the stopper cushioning member 30 is attached in the outer box, or the box body of the inner box accommodated in the outer box is fitted with the stopper cushioning member 30 as shown in FIG. To be completed.

  When there is no package in the packaging box 10 as after the package is delivered to the destination, the outer box B is folded and the box body A of the inner box and the horizontal support member 17 are separated, and the bottom plate 11 and side The face plates 12 and 13 can be folded, and the stopper cushioning member 30 can be folded to move as a compact size. FIG. 7 shows a perspective view of the stopper cushioning member 30 in a folded state.

  Next, each Example of the packaging box of this invention and its drop test result are demonstrated.

As a sheet-like nonwoven fabric 19, a polypropylene nonwoven fabric (trade name: Zaburn) 128BB (weight per unit area: 28 g / m ² ) manufactured by DuPont Co., Ltd. was preliminarily point-fused with a hot embossing roll to prevent fluffing, and then a corrugating machine A corrugated product having a corrugated height of 5 mm was used. Using this nonwoven fabric 19, six hammock portions 18 are formed, and a plywood (size: width 190 mm, depth 245 mm, height 11 mm, weight: 324.5 g) simulating the size and weight of a portable electronic device is viewed from the end. Each of the three hammock parts 18 other than the third one is housed, and the third hammock part 18 from the end is provided with an inner box containing a sensor for detecting the degree of impact, and the inner box is further housed in the outer box. A box was prepared as a test body of Example 1. The weight is 3.45 kg. For the inner box and the outer box, 5 mm thick damper plates were used.

  FIG. 8 is a schematic perspective view of the packaging box of the first embodiment. In the same figure, the packaging box 40 of Example 1 has a rectangular parallelepiped shape, and the impact detection sensor 41 is housed in the third hammock part from among the six hammock parts described above, and is attached by an adhesive member such as an adhesive tape. It is fixed. In FIG. 7, the impact degree detection sensor 41 is shown in order to indicate where it is stored in the packaging box 40. However, as described above, it is actually stored and fixed in the hammock portion as described above. It is not visible from the outside. The impact degree detection sensor 41 has impact values in three directions in total, that is, left and right lateral directions (X direction), top and bottom directions (Y direction), and back and front directions (Z direction) shown in FIG. Unit G) is detected.

  Table 1 shows the test results when the packaging box 40 was dropped in each of 10 directions from a position of 60 cm in height using a Taiwan model VS-1018 (single-arm pneumatic type) drop tester.

The basic configuration of the packaging box of Example 2 is the same as that of Example 1, but a mesh type netron Z-28P (made of polypropylene) having a basis weight of 288 g / m ² is used as the nonwoven fabric used for the hammock portion 18. . The packaging box 50 of the present embodiment can cope with a heavier packaged product than the packaging box 40 of the first embodiment. FIG. 9 is a schematic perspective view of the second embodiment. In this embodiment, the sensor for detecting the degree of impact is housed in the third hammock part from the end of the six hammock parts in the packaging box 50, and is fixed by an adhesive member such as an adhesive tape. Moreover, the test body of the packaging box 50 which accommodated the plywood in the remaining five hammock parts and whose total weight is 4.04 kg was prepared. The impact detection sensor has impact values (units) in three directions including the left and right side surfaces (Z direction), the top and bottom surfaces (Y direction), and the back and front surfaces (X direction) shown in FIG. G) is detected.

  Table 2 shows the test results when the test piece of the packaging box 50 is dropped in the 10 directions from the position of 60 cm in height using a drop tester of model VS-1018 (single-arm pneumatic type) made in Taiwan. Show.

  Moreover, the packaging box which has the inner box of the structure of FIG. 6 which mounted | wore with the stopper buffer member 30 was used using the Taiwan model VS-1018 (single-arm pneumatic type) drop test machine similarly to Example 1 and 2. FIG. Table 3 shows the test results when dropped in 10 directions from a position of 60 cm in height. In addition, the test body of a present Example is the same Zavern specification as Example 1, and is 3.45 kg in weight. In Table 3, the left and right side surfaces (X direction), the top and bottom surfaces (Y direction), and the back and front surfaces (Z direction) are the same as those of the packaging box shown in FIG. Moreover, the rubber band was used for product fixation.

From each detection result of Tables 1 to 3, it can be seen that the G value is less than 50 in all items. As a result, it can be said that each packaging box of the present example achieves the same level of impact as an existing returnable box based on air or an elastic film.

  The present invention is not limited to the above-described embodiments and examples. For example, a stopper that integrally forms the inner box body and the outer box and fixes the plurality of hammock parts from both left and right sides is fixed. By having the structure of the packaging box having, it is possible to prevent the horizontal support member from shifting and the hammock portion from rolling during transportation. That is, in this case, after forming the plurality of hammock parts as in the embodiment in a state in which the inner box body is assembled, when assembling the outer box and the stopper integrally formed with the inner box body, the stopper has the plurality of hammock parts. Assemble so that the whole is sandwiched from both sides.

  The position of the stopper needs to be 30 to 40 mm from the front surface (back surface). If it is larger than that, it becomes the position of the packaged product in the hammock part, which adversely affects the side impact.

  Further, the present invention is not limited to the above-described embodiment and examples. For example, the material of the stopper cushioning member 30 is not limited to the nonwoven fabric of the cushion material, and the purpose of fixing use may be achieved. For example, any material such as polystyrene foam, urethane foam, paper, etc. may be used. Further, only the portion of the top surface portion of the stopper cushioning member 30 that is not connected to the arm portion 32 has a tongue piece that extends to a position near the side plates 12 and 13 in a direction orthogonal to the width W direction. It is good.
