Description

  The present invention relates to a simple packaging box that protects against vibration and shock when transporting easily damaged articles.

  In general, articles, circuit boards, electrical products, etc. using materials that are easily damaged, such as glass, are packaged with foamed resin cushioning materials to protect them from external vibrations and shocks during transportation and transshipment. Packed in a box. Usually, these cushioning materials are designed in an optimal shape having a necessary cushioning capacity in accordance with the shape and weight of the article to be packed.

  However, although the cushioning material designed for the article to be protected is desirable from the viewpoint of the protective effect, the shape is limited and it cannot be used for other than the article. There was a problem that it was difficult to use.

Therefore, in recent years, a packaging box has been proposed in which a stretchable film can be attached to a frame made of cardboard or other cardboard with a window in the center, and the object to be packed is sandwiched between the film parts. (See Patent Documents 1 and 2).

  However, in the structure of the above conventional packaging box, since the film is affixed to the frame, it is extremely difficult to remove only the film cleanly and separate, and sufficient consideration is given to separation and reuse. It wasn't. In addition, since the object to be packed is sandwiched and packed by the film part, for example, when the object to be packed is a circuit board, there is a problem that an element mounted on the circuit board is likely to be bent due to impact or vibration during transportation. there were. Furthermore, since the work process of sticking a film to the frame is included in the manufacturing process of the packaging box, there is a problem that the manufacturing cost of the packaging box increases and the unit price of the packaging box also increases.

  An object of this invention is to provide the packaging box which can be packed in a suspended state, without pinching a to-be-packaged object. Another object of the present invention is to provide a packaging box that can be easily disposed of and reused, and that can reduce manufacturing costs and material costs.

  To achieve the above object, the present invention provides a top plate provided with a window in the center, a pair of slits provided at positions facing the non-window portion of the top plate with the window interposed therebetween, and the top plate A first holding member having a support foot formed continuously on the periphery of the rim, and an article to be packed housed therein are located in the window portion, and both ends in the length direction straddle the slits. A resin film bag member placed on the top plate in such an arrangement, and a second holding material loaded on the first holding material, the insertion piece being inserted into the slit from above the bag member And an outer box that accommodates the first and second holding members while the insertion piece is inserted into the slit.

  In addition, an elongated hole corresponding to the slit may be provided in the bag member, and the insertion piece may be inserted into the elongated hole and the slit.

  Further, the second holding member is continuous with the top plate provided with a window in the center, a pair of slits provided at positions facing the non-window portion of the top plate across the window, and the periphery of the top plate. And a support foot formed in a direction perpendicular to the top plate, and a tongue portion formed in a direction perpendicular to the lower end edge of the support foot and perpendicular to the support foot. And an insertion piece formed in a direction perpendicular to the tongue and at a right angle to the tongue, and the slit of one second holding member has another second holding member You may make it insert an insertion piece. According to this configuration, the second holding material can be stacked in a plurality of stages, and a plurality of items to be packed can be packed in a hierarchical state by one packing box.

  According to the packaging box of the present invention, since the object to be packed is contained in the bag member and held between the first and second holding materials in a suspended state, compared to a conventional packaging box sandwiched between film portions, Protects against damage or failure due to impact or vibration during transportation, even if the packaged object (for example, a circuit board or glass product) is barely covered with a strong exterior and has almost no pressure on the object to be packed. can do. In addition, since the work for holding the article to be packed contained in the bag member between the first and second holding materials does not use an adhesive, a tape, a string, etc., it is easy to separate and recycle, Material costs can also be reduced. In addition, when unpacking, the package member can be taken out while the packaged item remains in the bag member, so that the packaged item can be easily carried after unpacking.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  A first embodiment of the present invention will be described. FIG. 1 is an exploded perspective view of a packaging box according to the first embodiment of the present invention. The packaging box according to the present embodiment sandwiches the window 3 between a top plate 2 having a window 3 at the center and a non-window portion 4 of the top plate 2 (see FIG. 3, hereinafter referred to as “frame portion”). A first holding member having a pair of slits 5 provided at positions facing each other and a support foot 6 formed continuously to the periphery of the top plate 2 and in a direction perpendicular to the top plate 2. 1 and the resin 7 placed on the top plate 2 in such an arrangement that the packed object 7 accommodated therein is positioned in the window portion 3 and both end portions in the length direction straddle the slits 5. For example, a polyolefin) film bag member 8, a top plate 10 provided with a window 11 at the center, and a peripheral edge of the top plate 10, and formed in a direction perpendicular to the top plate 2. It has a support foot 12 and an insertion piece 13 inserted into the slit 5 from above the bag member 8, on the first holding material 1. A second holding member 9 which is the mounting, the first left plugged the insertion piece 13 into the slit 5, and a outer box 15 for accommodating the second holding member 1,9.

  FIG. 3 is a plan view showing a state before the first holding member 1 is assembled. The first holding material 1 is produced based on rectangular cardboard made of corrugated cardboard or the like. As shown by a broken line in FIG. 3, a crease is provided in the short side direction at a position separated from each short side of the cardboard by a predetermined distance. Thereby, the top plate 2 and the pair of support legs 6 can be formed. A rectangular window 3 is provided at the center of the top plate 2. A pair of slits 5 is provided at a position that is a non-window portion 4 of the top plate 2 and is opposed to the window 3. The first holding material 1 is assembled by folding both ends of the cardboard at a right angle with the crease.

  The resin film bag member 8 has a length sufficiently longer than the distance between the pair of opposed slits 5 and 5.

  FIG. 4 is a plan view showing a state before the second holding member 9 is assembled. The second holding material 9 is manufactured based on rectangular cardboard made of corrugated cardboard or the like. A rectangular window 11 is provided at the center of the cardboard. A pair of L-shaped cuts are provided at the peripheral edge of the long side of the cardboard at a predetermined distance from each short side, and at the center of the cardboard in the short side direction. A U-shaped notch is provided at a position closer to the shorter side than the letter-shaped notch. And as shown with the broken line in FIG. 4, the crease | fold is provided so that the ends of these L-shaped notches and the U-shaped notches may be connected. Further, the four corners of the thick paper are cut out into rectangular shapes having the same shape so that the short side length of the thick paper is substantially the same as the length of the slit 5. Thereby, the top plate 10, the pair of support legs 12, the pair of insertion pieces 13, and the two pairs of support columns 14 can be formed. The second holding member 9 having a three-dimensional shape is assembled by folding both ends of the cardboard at a right angle with the crease.

  The second holding material 9 has the same width and depth dimensions as the first holding material 1 (both dimensions are substantially the same as the width and depth dimensions of the internal space of the outer box 15). However, the height dimension can be appropriately adjusted by changing the size of the L-shaped notches or the four corner notches provided on the cardboard. Thereby, since the height dimension of the whole holding | maintenance material which match | combined the height of the 1st and 2nd holding | maintenance materials 1 and 9 can be made to correspond with the height dimension of the internal space of the outer box 15, 1st holding | maintenance material The holding member integrated by inserting the insertion piece 13 of the second holding member 9 into one slit 5 can be accommodated in the outer box 15 while maintaining its shape.

  At the time of packing, as shown in FIG. 1, an object to be packed 7 accommodated in the bag member 8 is positioned in the window portion 3, and both end portions in the length direction of the bag member 8 straddle the slits 5. The bag member 8 is placed on the top plate 2 in a simple arrangement, and the insertion pieces 13 of the second holding material 9 are inserted into the corresponding slits 5 from the top of the bag member 8 and the support feet 12 are made to stand on the top plate 2. In this manner, the second holding material 9 is stacked on the first holding material 1. And this package is accommodated in the outer box 15 and sealed. In addition, in this embodiment, although it was set as the outer box which opened the top | upper surface, a form will not be limited if a package can be sealed.

  As shown in the packing state in FIG. 2, the flexible film-like bag member 8 is partially formed in such a manner that both ends thereof are left on the top plate 2 by the insertion pieces 13 inserted into the slits 5. Is pushed into the lower side of the top plate 2. For this reason, the bag member 8 is tightly sandwiched between the top plate 2 and the insertion piece 13 inside each slit 5 at two locations, and the bag member 8 is hooked in a U shape on the lower end of the insertion piece 13. It becomes a state, and the movement with respect to the length direction is restricted. Therefore, the to-be-packaged object 7 accommodated in the bag member 8 is firmly held in a floating state.

  According to the packaging box of the present embodiment, the packaged item is accommodated in the bag member and held between the first and second holding materials 1 and 9 in a suspended state, so that the conventional packaging box is sandwiched between the film portions. Compared to the above, there is almost no pressure on the object 7 to be packed and it is not covered with a solid exterior, so to speak, the object to be packed (for example, a circuit board or glass product) is affected by shock or vibration during transportation. It can protect against damage and failure. In addition, the work of holding the article 7 contained in the bag member 8 between the first and second holding materials does not use an adhesive, tape, string, etc., so that it can be easily disposed and reused. Costs and material costs can also be reduced. Moreover, since the packaged material 7 can be taken out from the bag member 8 when unpacked, the packaged material after unpacking can be easily carried.

  In addition, although this embodiment demonstrated the case where a pair of slit 5 which opposes the long side direction of the top plate 2 across the window 3 of the top plate 2 of the 1st holding material was provided, the short side of the top plate 2 is further provided. Another pair of slits facing each other may be provided, and a pair of support legs and insertion pieces may be added to the second holding member 9 in correspondence with the new slits. Further, support legs 6 may be provided on all four sides of the frame portion 4 of the top plate 2 of the first holding member 1.

  In the present embodiment, the bag member 8 is directly pushed into the slit 5 by the insertion piece 13 and held. However, as shown in FIG. 5, the slit 5 is positioned at a position corresponding to the slit 5 of the bag member 8. The same effect as described above can be obtained by providing the elongated hole 16 having substantially the same size as that of the bag member 8 and inserting the insertion piece 13 into the elongated hole 16 and the slit 5 from above the bag member 8.

  A second embodiment of the present invention will be described. In the description of the present embodiment, the same parts as those in the packaging box according to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
