Description

  The present invention relates to an exterior box, and more particularly to an exterior box for packing a thin interior box.

  In order to transport a rectangular plate-shaped product, for example, a thin interior box containing a large glass dry plate, a large exterior box made of cardboard is used. A plurality of, for example, two interior boxes are placed in one exterior box. In this work, two workers facing each other cooperate to lift the inner box and insert them one by one from the upper opening of the outer box.

  Note that the glass dry plate, unlike a normal photographic film, has excellent flatness retention, so that an accurate projection pattern without distortion can be obtained. For this reason, it is used when creating a CRT shadow mask, a back electrode pattern of a plasma display, a printed circuit board used in electronic equipment, and the like. Such a glass dry plate has a thickness of 5 mm, a surface size of 813 × 1379 mm or 914 × 1114 mm, and a weight of about 12 kg.

  By the way, recently, an ultra-large glass dry plate which is advantageous in terms of cost has been used. This ultra-large glass dry plate has, for example, a surface size of 980 mm × 1670 mm, 1100 mm × 1550 mm, 1100 mm × 1350 mm, a thickness of 5 mm, and a weight of about 20 kg. If such a glass plate is packaged two by two as usual, the weight of the inner box will be about 40 kg. The operation of lifting such a heavy inner box and putting it in the outer box is a problem because it is very hard work.

  An object of this invention is to provide the exterior box which reduces the work burden of an operator.

  The exterior box of the present invention includes a pedestal that vertically stands a rectangular thin interior box containing a plate-like product inside with one side end face down, and an interior box erected on the cradle. A pair of shock-absorbing materials that are mounted on two vertical sides sandwiching the one side and absorb shocks to the interior box, and are covered with the inner surfaces of the side portions of the shock-absorbing material so as to be in close contact with each other. A cylindrical member that surrounds the side of the base and the shock-absorbing material, and a cap member that is attached to the cylindrical member so as to close the opening on the opposite side of the receiving base of the cylindrical member. .

  The opening on the cradle side of the cylindrical member is covered with a tray member so as to close the opening. Further, the cradle includes a pedestal that receives an end surface of the one side of the inner box, and a plurality of protrusions that are provided on one surface of the pedestal and constitute a groove into which the one side of the inner box is inserted. It is characterized by comprising. Further, the length of the cradle in the longitudinal direction is shorter than the length of the one side of the inner box so that both end portions of the one side of the inner box protrude from the both end portions in the longitudinal direction by a predetermined length. It is characterized by.

  According to the exterior box of the present invention, a rectangular thin interior box is vertically set up on a cradle, and shock cushioning materials are mounted on two vertical sides sandwiching one side of the interior box. Cover the interior box, the cradle and the side of the shock absorbing material with a cylindrical member so that the inner surface is in close contact with the inner surface, and cover the opening on the opposite side of the tubular member from the cradle with a cap member. As a result, the interior box can be packed without being lifted, and the work burden on the worker can be reduced.

  Moreover, if the tray member is put on the opening on the cradle side of the tubular member so as to close it, the protection of the interior box can be further strengthened. Further, since the cradle is composed of the pedestal and the ridge, the interior box can be erected with a simple configuration. In addition, the length of the cradle in the longitudinal direction is shorter than the length of one side of the interior box, and both end portions of the interior box protrude a predetermined length, so that the corners of the interior box can be floated and held, When the box is dropped, it is possible to prevent an impact from being transmitted to the corners of the product, and an operator can easily put his hand under the inner box when lifting the inner box when unpacking.

  In FIG. 1 showing an embodiment of the present invention, an exterior box 10 is configured such that one of the long sides 12a and 12b of a rectangular thin interior box 12 has its long side 12a side down and the interior box 12 is substantially vertical. A cradle 14 to be erected, a pair of side pads 16 that are shock absorbers attached to the short sides 12c and 12d of the interior box 12, and the side pads 16 that are covered from above the interior box 12 (on the long side 12b side). A sleeve 18 in the form of a quadrangle that surrounds the cradle 14, the interior box 12, and the side pad 16, and is dropped from the opening 18 a on the upper side of the sleeve 18 onto the long side 12 b of the interior box 12. A top sheet 20 placed as described above, a ground sheet 22 that is integrally bonded to the lower part of the cradle 14, a cap 24 that covers the sleeve 18 from above and closes the opening 18a, and a slip sheet from below. Consisting close the tray 26. The opening 18b suffer Bed 18. Reference numeral 28 denotes a known wooden pallet on which the outer box 10 is placed.

  The interior box 12 houses one or two glass plates as a plate-like product. As is well known, a glass dry plate is obtained by coating an emulsion on one side of a glass plate. For example, the glass plate has three types of 980 mm × 1670 mm, 1100 mm × 1550 mm, 1100 mm × 1350 mm, a thickness of 5 mm, and a weight of about 20 kg.

  In this embodiment, a glass dry plate having a size of 980 mm × 1670 mm × 5 mm is used. Therefore, the outer box 10 of the present embodiment has a size of 1160 mm × 2010 mm × 550 mm and a total weight of about 63.0 kg. When a glass dry plate having a size of 1100 mm × 1550 mm × 5 mm is used, the outer box 10 has a size of 1295 mm × 1890 mm × 550 mm and a total weight of about 62.7 kg.

  The sleeve 18 is made of corrugated cardboard, and is manufactured by arranging corrugated cardboard flutes in a vertical direction so as to withstand pressure from the top and bottom. Further, the height H1 of the sleeve 18 is longer than the length H2 of the side pad 16, and the length H2 of the side pad 16 is set longer than the length H3 of the short sides 12c and 12d of the interior box 12. Yes.

  The side pad 16 has a rectangular board 16a made of corrugated cardboard, three elongated rectangular bar-shaped ribs 16b bonded to one surface, and two elongated rectangular bar-shaped plates bonded to the other surface. It consists of a rib 16c. The ribs 16b and 16c are made of styrene foam or formed by folding cardboard into a square bar shape.

  The rib 16b constitutes a groove into which the short sides 12c and 12d of the interior box 12 are inserted. The rib 16c forms a shock absorbing space S1 having a distance d1 of about 30 to 50 mm between the plate 16a and the sleeve 18 (the inner wall surface of the sleeve 18 and the rib 16c are in close contact). Even if an impact is applied from the side, the impact is not transmitted directly to the short sides 12c and 12d of the interior box 12.

  The cradle 14 is equidistant from three ridge members 34, 35, 36 arranged in parallel so as to form two grooves 14 a (see FIG. 2) sandwiching the long side 12 a of the interior box 12. And five pedestals 38 (see FIG. 3) which are arranged in a straight line and are bonded to the lower surfaces of the protrusion members 34 to 36 and connect the protrusion members 34 to 36.

  As shown in FIG. 2, each of the protrusion members 34 to 36 is formed by stacking a plurality of rectangular cardboards and bonding the facing surfaces to each other. (See FIG. 3). This increases the adhesion area and increases the stability. Further, the corners 34a, 35a, 36a serving as the mouth portions of the groove 14a are tapered and tapered so that the long side 12a of the inner box 12 can be easily inserted.

  The pedestal 38 is provided with a protrusion 38a so as to enter the groove 14a, and a rectangular plate-like cardboard 37 is bonded to the upper surface thereof. This is because the pedestal 38 is formed by stacking a large number of cardboards and bonding the surfaces in the same manner as the ridge members 34 to 36, so that the interior box 12 is directly attached to the end surface of the ridge portion 38a. This is because the inner box 12 is rubbed and easily damaged when hit.

  In addition, the ground sheet 22 bonded to the lower surface of the pedestal 38 protrudes laterally from the center of both side ends with a width substantially the same as the length of the protrusion members 34 to 36, and a pair of guide plates 22a. Is formed. The guide plate 22a is folded up from the ground sheet 22 so as to be inclined between the upper ends of the ridge members 34 and 36, and the end thereof is on the upper surface of the ridge members 34 and 36. It is glued. When the guide plate 22a is inserted between the opening 18b of the sleeve 18 between the receiving base 14 and the peripheral wall 26a of the tray 26, the opening 18b of the sleeve 18 is not caught by the receiving base 14, and the receiving base 14 And the peripheral wall portion 26a. As described above, since the cradle 14 and the ground sheet 22 are integrated in advance, the assembly efficiency of the outer box 10 is further improved.

  Further, when the interior box 12 is erected on the cradle 14, the depth of the groove 14 a is not necessary so that the interior box 12 can be stably and substantially self-supported without falling down without being supported by hand. d2 is about 10 to 30% of the height of the inner box 12 (the length of the short sides 12c and 12d), and the weight of the cradle 14 is moderate, for example, about 25 to 45% of the weight of the inner box 12. Is desirable. In the present embodiment, the depth d2 of the groove 14a is about 150 to 250 mm, and the weight of the cradle 14 is about 14.0 kg.

  As shown in FIG. 3, the length L1 of the cradle 14 is set to be shorter than the length L2 of the long sides 12a and 12b of the interior box 12. As a result, as shown by broken circles 39 and 40, both ends of the inner box 12 protrude from the both ends of the cradle 14 by a predetermined length ((L2-L1) / 2)), and depending on the thickness of the pedestal 38 Spaces S2 and S3 are formed between the long side 12a of the interior box 12 protruding from both ends of the cradle 14 and the ground sheet 22.

  Even when the outer box 10 is accidentally dropped during transportation or the like, the spaces S2 and S3 can prevent a strong shock from being applied to the corner of the inner box 12, that is, the corner of the glass dry plate inside. it can. Further, when unpacking the outer box 10, the lower part of the inner box 12 can be easily grasped by inserting a hand into the spaces S2 and S3, so that the inner box 12 can be easily taken out.

  In order to assemble the exterior box 10 configured in this way, first, the tray 26 is placed on the pallet 28, and the cradle 14 is placed therein. Then, the two workers face each other and lift the first interior box 12 substantially vertically, so that the central portion of the long side 12a of the interior box 12 and the central portion of the cradle 14 are substantially aligned. The long side 12 a of the box 12 is inserted into the groove 14 a of the receiving base 14. At this time, since the corners 34a, 35a, 36a serving as the mouth portions of the groove 14a are tapered, the inner box 12 can be smoothly inserted into the groove 14a without being caught.

  Subsequently, similarly, the second interior box 12 is placed on the receiving base 14. In this work process, the height for lifting the interior box 12 is about 200 to 300 mm, and a short time is required. Further, since the interior box 12 inserted into the groove 14a of the cradle 14 is self-supporting without being supported by hand, the subsequent work can be performed very easily.

  Next, the side pad 16 is attached to the short sides 12c and 12d of the interior box 12 so that the short sides 12c and 12d of the interior box 12 are inserted into the grooves formed by the ribs 16b of the side pad 16. At this time, the lower part of the side pad 16 enters the inside of the tray 26. Thereafter, the two workers work together to lift the sleeve 18 and put it over the interior box 12. Thus, the opening 18b below the sleeve 18 is inserted into the gap between the cradle 14 and the peripheral wall 26a of the tray 26 without being caught by the cradle 14 by the guide plate 22a. Further, the inner wall surface of the central portion of the sleeve 18 is brought into close contact with the side portion of the side pad 16.

  Since the upper part (long side 12b) of the inner box 12 is exposed to the opening 18a above the sleeve 18, the top sheet 20 is placed on the upper part of the inner box 12 so as to drop into the opening 18a. To do. Then, a cap 24 is placed over the top to close the opening 18a of the sleeve 18, whereby the first outer box 10 is completed. Similarly, the second outer box 10 is completed on the pallet 28.

  Thereafter, as shown in FIG. 4, when the two exterior boxes 10 are tightened together with the pallets 28 by a plurality of bands 41, the two exterior boxes 10 are integrated with the pallet 28 and are subjected to some impact. It will be in a stable state without falling down. The two outer boxes 10 can be easily transported to a warehouse or the like by a known hawk lift.

  In addition, after fastening the two exterior boxes 10 together with the pallet 28 with the band 41 and further covering the openings of the cap 24 and the tray 26 with a stretch film, dust can be prevented from entering the exterior box 10, The dustproof effect is improved. Further, by covering the side of the outer box 10 and the pallet 28 from above the band 41 with the stretch film, there is an effect of further tightening the band 41 and preventing the outer box 10 from being laterally displaced from the pallet 28.

  Further, in order to unpack the outer box 10, the reverse of the above-described assembly process may be performed. However, since there are spaces S2, S3 between the long side 12a of the inner box 12 and the ground sheet 22, this space S2 , S3, the lower part of the inner box 12 can be easily grasped and the inner box 12 can be easily taken out.

  In the embodiment described above, the cradle is composed of three ridge members and five pedestals. However, the present invention is not limited to this, and for example, two ridge members and one pedestal. (One plate-like pedestal having substantially the same length as the protrusion member) may be used. Moreover, in the said embodiment, although the two interior boxes accommodated in an exterior box were used, this invention is not limited to this, For example, it is good also as 1 piece or 3 pieces. In the above embodiment, a glass dry plate is used as the plate-like product.
