Description

  TECHNICAL FIELD The present invention relates to an article transport packaging tool for storing and transporting various articles, and more particularly to an article transport packaging tool suitable for home delivery.

  Conventionally, as a packaging for transporting articles, for example, a pair of hard frames 23, 23 in which a central opening 21 on a plate surface is covered with a flexible film 22 as shown in FIG. , 23, a packaging tool is known in which an article is sandwiched in an outer box 24 to protect the article 25 from impact (see Patent Document 1). When using the above-mentioned packing tool, corrugated cardboard is used for the pair of frames 23, 23, and the four peripheral edges thereof are individually folded along folding lines 26 previously attached to the plate surface, and the connection portion is supported by the film 22 by the film 22. As shown in FIG. 6, the article 25 is packed by sandwiching the article 25 between the frames 23, 23 and storing the article 25 in the outer box 24. 23 is stored in the outer box 24 at a position corresponding to the height of the support portion 27 formed on the four sides of the outer wall 23 at a distance from the bottom 28 and the lid 29 of the outer box 24, and may be added from above and below the outer box 24. The article 25 can be effectively protected from an impact that does not occur.

Incidentally, when the packaging article 25, the packaging component described in Patent Document 1, as seen in FIG. 5, the frame 23 to be fitted earlier on the box 24 the first frame, the article 25 from the outside When the second frame is the frame that is suppressed and fitted into the outer box 24, the support portion 27 of the second frame 23 must be bent and fitted into the outer box 24. While holding the support portion 27 so as not to return to a flat surface, the packing tool must be held in a certain three-dimensional shape, and the object 25 must be stored using both hands. It was not always easy.

  The problem to be solved is that when the baseboard is folded in the field to form the support part around the frame, the baseboard is folded back along the folding line so that the connecting part does not return to the plane. Since the storage operation of the article has to be performed while suppressing, the storage operation is not always easy.

The most important point of the present invention is that when the support portion is folded along the folding line, the restoring force of the film acts on the support portion so that the support portion is kept folded. Features.

  When the support part of the four circumferences of the frame is folded back along the folding line attached to the base board, the edge of the stopper formed in a part of the folding line protrudes into the gap formed by the notch of the stopper part, Since the support part is supported by the edge of the stopper and keeps the posture of being folded back from the frame, it is not necessary to perform the work while holding the support part by hand so that it does not return to a flat surface as in the past. Can be easily stored.

  Further, the edge of the stopper protrudes outward from the plate surface of the support portion to support the film, and the film is tensioned by the amount of the protrusion. When the article is sandwiched between the packing tools and stored in the outer box, the article can be stably fixed between the pair of packing tools without causing a lateral shift of the article in the outer box.

  The support attached to the base board without adding any other special components to the shape of the bent part to maintain the bent state after folding the base board at a right angle with respect to the center frame. This was achieved simply by notching a part of the folding line.

  The packaging tool for transporting goods according to the present invention uses an assembly of a pair of packaging tools in which a film is pasted on the opening of a frame as an interior material, and the article is sandwiched between both assemblies and accommodated in an outer box. It is.

  In the present invention, two baseboards made of corrugated paper in which a film excellent in elasticity such as urethane resin is stretched over an opening are used, and the baseboards are folded and assembled. The article to be packed is not limited to a flat article but may be a tall article. Moreover, an article can be seen through by using a transparent film as a film. However, from the viewpoint of the packaging function, transparency or opacity of the film is not a problem.

  FIG. 1 shows a base board to be assembled in an assembly constituting the packing tool of the present invention. In FIG. 1, the base board 1 is cardboard paper. The paper surface is partitioned into a frame 2 portion in the central region and support portions (3a, 3a and 3b, 3b) around the frame 2. In this embodiment, rectangular corrugated paper is used for the base board 1.

  The outer part of the frame 2 is a support part of the frame. A support part is a part which forms the surrounding wall of fixed height in the four periphery of a flame | frame. For convenience of explanation, the support portion formed outside the long side of the frame is referred to as a side support portion 3a, and the support portion formed outside the short side of the frame is distinguished as an end support portion 3b. The side support portion 3a is defined from the frame 2 by the side folding curve 4a, and the end support portion 3b is defined from the frame 2 by the end folding curve 4b.

  An opening 5 is formed in the center of the frame 2, and the opening 5 is covered with a film 6 excellent in elasticity and elasticity, such as a transparent polyurethane film, applied to the surface of the frame 2. The outer edge of the frame straddles the side part of the frame 2 and the end folding lines 4a and 4b, and is bonded to the plate surfaces of the side support part 3a and the end support part 3b by heat welding. However, the adhesion of the film 6 is not necessarily limited to thermal welding, and may be adhered to the support portion using an adhesive or an adhesive tape.

  The four corners of the base board 1 where the side fold curve 4a and the end fold curve 4b intersect are provided with cuts 7 extending from the edge of the base board 1 toward the side fold curve 4a to the end fold curve 4b. The four corners are separated from the formation part of the end support part 4b, and the folding line 4c on the extension of the end folding line 4b is attached to the formation part of the side support part 3a and is attached to both ends of the side support part 3a. A connecting portion 3c is formed. The connecting portion 3c is cut out to a certain depth from the side edge of the side support portion 3a as a means for connecting the side support portion 3a and the end support portion 3b to a trapezoidal fitting groove 8. In correspondence with the position of the fitting groove 8, the end support portion 3b is cut into a certain depth in the direction in which the interval is narrowed from the edge, and the tongue-like part 9 is fitted into the fitting groove 8. Is formed.

  In the present invention, the stopper 10 for further supporting the support portion is formed on the plate surface of the base board 1 divided into the frame 2 portion in the central region and the support portions (3a, 3a and 3b, 3b) around the frame 2. It is a thing. In the following description, the stopper that mainly supports the side support portion 3a will be described, but this also has the same function as the stopper that supports the end portion support portion. As shown in FIG. 2 (a), the stopper 10 has a first cut line 11a drawn parallel to the side folding line 4a on the plate surface of the side support portion 3a, and the first cut line 11a. Three sides are surrounded by the second cut line 11b that starts from the plate surface of the frame 2 corresponding to both end positions and reaches the first cut line 11a, and extends from the frame 2 side to the side support part 3a side. It is the part formed.

  The stopper 10 projects into the gap between the side fold curve 4a and the first cut line 11a when the side support portion 3a is bent at a right angle to the surface of the frame 2 along the side fold curve 4a. Further, as shown in FIGS. 2, (a) and (b), a part of the side portion further protrudes from the gap onto the plate surface and supports the edge of the side support portion 3a cut out by the stopper 10. If the distance between the side fold curve 4a and the first cut line 11a is too wide, a gap will be formed between the stopper 10 and the notch edge of the notched side support portion 3a, and it will not function as a stopper. . In practice, the first cut line 11a is placed on the plate surface of the support portion 3a at a distance slightly longer than the thickness of the base board from the folding line of the support portion 3a drawn on the base board 1. It is desirable to be drawn on the plate surface of the side support portion 3a in parallel with the folding line 4a of the portion 3a.

  The stopper of the side support portion 3a has been described above, but the same applies to the stopper 10 of the end support portion 3b. Although the illustration of the stopper 10 of the end support portion 3b is omitted, a first cut line drawn in parallel to the end folding line 4b on the plate surface of the end support portion 3b, and the first cut line It is formed by extending from the plate surface of the frame 2 in correspondence with both end positions and being surrounded by the second cut line reaching the first cut line and projecting from the frame 2 side to the end support portion 3b side. Is done. In this embodiment, the stopper 10 is provided at several positions at regular intervals on each side of the frame 2 while ensuring the strength of the connecting portion between the frame 2 and the both side support portions 3a or both end support portions 3b. It has been. In this embodiment, an example is shown in which the stoppers 10 are formed at three locations at regular intervals on the long side and the short side of the frame 2, respectively.

  Next, the point which packs goods using the packing tool of this invention is demonstrated. The packing tool of the present invention is configured by combining a pair of assemblies. Next, the assembly procedure of the assembly will be described. In FIG. 3A, first, the both side support portions 3a and 3a of the base board 1 are bent in the same direction along both side folding curves 4a and 4a, leaving the portion of the stopper 10 surrounded on three sides by the cut line. Stand upright. By raising the side support portion 3a, the connecting portions 3c at both ends thereof are also raised integrally. When the side support portion 3a is erected at a right angle with respect to the frame 2 of the base board 1, the elasticity of the film 6 attached to the side support portion 3a acts on the side support portion 3a and returns to the flat plate. As shown in FIG. 2, the stopper 10 protrudes into the gap opened on the side folding curve 4a as shown in FIG. 2, and the side facing the gap by the paper surface of the corrugated paper and its elastic action. The edge of the part support part 3a is supported, and the side part support part 3a is kept in the bending posture.

  Next, as shown in FIG. 3B, the connecting portions 3c at both ends of the side support portion 3a are folded at a right angle along the folding line 4c. Further, as shown in FIG. 3C, the end support portion 3b is folded at a right angle along the end fold curve 4b, and the inner surface thereof is overlapped with the outer surface of the connecting portion 3c. Also in this case, as described above, the stopper 10 protrudes into the gap opened on the end folding curve 4b and supports the base end of the end support portion 3b facing the gap to support it in the bent posture. .

  Next, as shown in FIG. 3D, the tongue portion 9 provided corresponding to the position of the fitting groove 8 of the connecting portion 3c is fitted with the base portion connected to the plate surface of the end support portion 3b as an axis. In the trapezoidal opening of the groove 8, it is tilted in a substantially horizontal position, both side edges of the tongue 9 are supported by the inner wall of the fitting groove 8, and the tongue 9 is held in the fitting groove 8 by the wedge action of the inclined surface. The part support part 3 b is connected to the side support part 3 a via the connection part 3 c, and a peripheral wall having a constant height is formed on both sides and both ends of the frame 2 to assemble the box-shaped assembly 12.

  In FIG. 3 (e), by the above operation, the frames 2 and 2 of the assembled assemblies 12u and 12d forming a pair are faced up and down, and the film 6 pasted on the frame 2 of the lower assembly 12d. The article 13 to be stored is placed on the surface, the upper assembly 12u is pushed down from above, the article 13 is sandwiched between the films 6 and 6 of both frames 2 and 2, and the frames 2 and 2 of both assemblies 12u and 12d are placed. Are pressed to a position where they are in contact with each other and stored in the outer box 14, the outer box 14 is covered with a lid 15, and the lid 15 is sealed with an adhesive tape to complete packing of the article 13.

  In the outer case 14, as shown in FIG. 4, the peripheral wall forming the support portion of the lower assembly 12d is supported by the bottom 16 of the outer case 14, and the peripheral wall forming the support portion of the upper assembly 12u is outside. Supported by the lid 15 of the box 14 and the planes of the base boards of the frames 2 and 2 of the assemblies 12u and 12d are in close contact with each other, and the article 13 is stabilized by the elasticity of the films 6 and 6 of the assemblies 12u and 12d. Supported by.

  As described above, in the present invention, when the side support portions 3a and 3a are first bent at a right angle with respect to the plane of the frame 2, the stopper 10 is further removed from the gap in the bottom of the side support portion 3a. In order to prevent the side support portions 3a and 3a from returning due to the repulsive force of the film 6 and to keep the folded posture, the following operation is performed while the side support portions 3a and 3a are kept in the folded posture. It is not necessary to support the side support portions 3a and 3a when bending the connecting portion 3c and subsequently bending the end support portion 3b.

  Furthermore, after the end support portion 3b is bent, the end support portion 3b is supported by the stopper 10 and acts on the repulsive force of the film 6 when the tongue portion 9 is bent into the fitting groove 8. Therefore, the subsequent operation is facilitated, the assembly can be assembled in a short time, and the work efficiency of home delivery can be improved.

  Further, the stopper 10 not only holds the side and end support portions during assembly work of the assembly, but also protrudes outward from the gap of the side support portion 3a as the support portion is bent. A part of the film 10 tensions the film 6 in both directions of the frame 2, and a part of the stopper 10 protruding outward from the gap of the end support part 3 b tensions the film 6 in the front-rear direction of the frame 2. Therefore, the article 13 can be tightened between the pair of assemblies 12u and 12d and stably packed in the outer box 14. Further, by using a transparent film for the film 6 stretched over the frame 2, the packing state of the article 13 packed in the outer box 14 can be confirmed from above (or below) the assembly.

  The packing tool according to the present invention is not limited to being used as a package for delivering goods, but can be widely used as a packing tool for transporting and storing articles that are particularly easily damaged.
