Prior art

Conventionally, when transporting products such as computers and various home appliances, cushioning materials such as foamed styrene foam and bubble wrap are provided in an outer box made of cardboard to protect them from shock and vibration during transportation. They were packed in large quantities and products were buried in the cushioning material. In order to prevent damage to the products, outer boxes that were considerably larger than those products were used. Therefore, a large space was required when storing and transporting the packed products. In addition, the workability during packing and unpacking was poor due to the use of cushioning material. In addition, these cushioning materials were sometimes reused, but because they were incombustible, they would have to be landfilled when disposed of as garbage. From the viewpoint of the problem, it was desired to stop using them or reduce their use.

The present invention relates to a packing material, a packing box, and a packing, which are capable of compacting a packing material (a packing material packed in a cardboard box or the like) and greatly improving workability in packing and unpacking. The purpose is to provide a method.

In addition, since the packing material 1 does not have the supporting feet 5, the outer box 1 1 has the frame 2 that supports the packing material 1 provided inside the outer box and continuously with the outer box. The one having the support member 12 is used. The support member 12 has a slit, into which the frame portion 2 of the packing material 1 is inserted.

FIG. 16 is a perspective view showing a state in which 20 items to be packed are packed in the packing box 10 of the present invention. In this example, the packaging box 10 of the present invention is made up of two packing materials 12 and an outer box 11 shown in FIG. 2 or FIG. The article to be packed 20 is supported by the elastic films 4 and 4 existing in the window portions 3 and 3 by the two packing materials 1 and 1. Note that FIG. 16 illustrates a case where the outer case 11 is transparent for easy understanding of the state of the inside of the outer case 11. However, in the packaging box of the present invention, the outer box 11 is not limited to a transparent one. The same applies to the examples shown in FIGS. 17 to 19 below.

FIG. 17 is a plan view showing the packaging box 10 of the present invention in which the packaging material 1 and the outer box 11 are integrated. When assembled, the packaging box shown in Figure 16 is obtained.

In the packaging box 10 of the present invention, a support member 13 that is independent of the outer box 11 and may be used by being brought into contact with the inside of the outer box 11 may be used as a support member. . Examples of such independent support members 13 include those described in FIGS. 21, 22, 23, 24, 25, and 26.

The independent supporting member 13 in FIG. 21 is a supporting portion composed of a rectangular upper surface 14 and two rectangular side surfaces 15 and 15 that are provided contiguously and substantially at right angles to the upper surface 14. 16 and a quadrangular foot portion 17 provided on each side surface 15 and substantially at right angles to each side surface. The support part has a notch 18 for supporting one of the packing materials 1 in pairs or folded and doubled. The width of the notch 18 is equal to or greater than the thickness of the object 20 to be packed and supported by the packing material 1 at the center of the upper surface 14, and the both sides and the side surface of the upper surface 14. In the case of 15, the thickness is almost equal to the thickness of two sheets of packing material 1 (frame part 2).

In the example of FIG. 21, there are many cuts 18, but the number of cuts 18 is not limited and may be one or many.

The independent support member 13 in FIG. 22 has a rectangular bottom surface 19, and two rectangular side surfaces 15 and 15, which are continuous with the bottom surface 19 and provided substantially at right angles to the bottom surface 19, respectively. It consists of two rectangular upper surfaces 14, 14, which are continuous with the side surfaces 15 and provided substantially at right angles to each side surface 15. Each side surface 15 and each upper surface 14 have a notch 18 to support one packing material 1 in pairs or folded and doubled packing material 1 . The width of the cut 18 is almost equal to the thickness of the two sheets of the packing material 1 (frame portion).

In the example of FIG. 22, there is only one cut 18, but the number of cuts 18 is not limited and may be one or many.

The independent supporting members 13 a and 13 b in FIG. 23 are respectively formed with a bottom surface 19 and two side walls 1 of a rectangular shape provided continuously with the bottom surface 19 and at a substantially right angle to the bottom surface 19. 5, 15 and a supporting portion 16 consisting of a rectangular upper surface 14 which connects the two side surfaces 15 and 15 and is provided substantially at right angles to each side surface 15. The supporting part 16 is provided on both sides 15 and 15 and the upper surface 14 for supporting the packing material 1 in a pair or by folding the packing material 1 into two _f ( It has a notch 18. The width of the notch 18 is approximately equal to the thickness of the two sheets of packing material 1 (frame part).

The independent support member 13a in FIG. 24 is a modified example of the independent support member 13 in FIG. 23, and is an example having three cuts 18.

The independent support member 13 of FIG. 25 is also a modification of the independent support member 13 of FIG. In this example, there are two support portions 16.

The support members 13 independent of the outer box 11 hold the packaged object 20 therebetween. Therefore, after the supporting packing material 1 is supported by inserting it into the cut 18, it is put into the outer box 11. Of course, after storing the support member 13 in the outer box 11, the packing material 1 supported by sandwiching the packaged object 20 may be inserted into the cut 20. The support member 13 taken out of the outer box 11 can be displayed as it is.

In the example shown in the above figure, the notch 18 is not formed to reach the bottom surface 19, but if the packing material 1 does not have the notch 8, the notch 18 is Formed to reach 9.

The independent support member 13 in FIG. 26 is a support portion 1 consisting of a bottom surface 19 and two square sides 15, 15 which are continuous with the bottom surface 19 and provided substantially at right angles to the bottom surface 19. Consists of six. The distance between the side surfaces 15 and 15 of the support portion 16 is approximately equal to the thickness of the two sheets of packing material 1 (frame portion).

In this example, packing material 1 is inserted between two side surfaces 15 and 15 in pairs or folded and doubled, and supported. Also in this example, a plurality of support portions 16 may be provided.

Next, an embodiment of the packing method of the present invention will be described in detail.

The example shown in FIG. 15 will be described.

First, the packing material 20 shown in FIG. 1 or FIG. 14 or the packing material 1 shown in FIG. 9 is bent at the bendable portion 6 to sandwich one packaged object 20. The article to be packed 20 is sandwiched and supported by the elastic film 4 of the packing material 1. Next, 20-packed items and packing material 1 (two or one set) sandwiching them are put into the outer box 11 as a set. At this time, two frames 2 of the packing material 1 are inserted into the slits of the support member 12 of the outer box 11. Close the lid (not shown) of the outer box 11 and, if necessary, secure it with adhesive tape so that the lid does not open, and the package is completed.

The package may be stored and transported either vertically or horizontally. However, if the package is heavy, it is preferable to store and transport the package so that the largest area of the package is horizontal.

In cases where the items to be packaged are relatively light, etc. A package that can support a plurality of objects to be packed, such as those described above, can be packed in the same manner as above.

Conversely, if it is necessary to support the packaged object 20 with a larger force, the packing material 1 shown in Fig. 12 is composed of two packing materials 1 and 1. Two sets of packing materials 1 and 1 belonging to two different sets adjacent to each other (one for each set) are in contact with each other at the bottoms of the supporting feet 5, or one of the packing materials 1 is supported. Combine so that the bottom of the foot 5 contacts the frame part 2 of the other packing material 1 (the surface on the side with the supporting feet 5), and the frames of the packing materials 1 and 1 that make up each set. The parts 2 and 2 may be inserted into the slit of the support member 12 of the outer box 11 and packed.

Next, an example shown in FIG. 16 will be described.

First, the packing material 1 shown in FIG. 2 or FIG. 13 (however, after assembly) is placed in the outer box 11. Since the supporting material 5 is present in the packing material 1, the window portion 3 is located above the bottom surface of the outer box 11. The object to be packaged 20 is placed on the window portion 3 (the elastic film 4 is present here) of the packing material 1. Next, the other packing material 1 is placed in the opposite direction to the packing material 1 put in the outer box 1 earlier, that is, the window portion 3 (where the elastic film 4 is present) is to be packed. Put it in the outer box 1 1 in a direction that covers the object 20. In this way, the packaged object 20 is supported by the elastic film 4. When the lid of the outer box 1 1 is closed and the lid is closed with adhesive tape to prevent the lid from opening as necessary, the package is completed.

Alternatively, first, the object 20 to be packed may be sandwiched between two packing materials 1 and then put into the outer box 11 in that state.

Moreover, you may pack similarly using the packing material 1 shown in FIG.

When using the packaging box 10 shown in Fig. 17 (in which the packaging material 1 and the outer box 11 are integrated), the window part 3 (here, elastic The process of placing the packaged object 20 on the film 4 is present.

An example of a packing method when the packing material 1 shown in FIG. 4 is used is as shown in FIG. That is, first, the packing material 1 is bent as shown in FIG. 18 (a), and the object to be packed 20 is inserted into the space between the elastic films 4 formed as a result. Next, the packing material 1 and the article to be packed 20 are put into the outer box 1 1 as they are (Fig. 18 (b) reference). In this way, the object to be packed is supported by the elastic film 4. Close the lid of the outer box 1 1, and if necessary, stop the lid with an adhesive tape to prevent the lid from opening.

When the thickness of the article 20 to be packed is small, the packing material 1 shown in FIGS. 7 to 9 can be used instead of the packing material 1 shown in FIG.

The packing method when the packing material 1 shown in FIG. 6 is used is as shown in FIG. That is, as shown in FIG. 19 (a), first, two packing materials 1,

1 sandwiches the two packages 20a and 20b. At this time, these packages 20a and 20b are sandwiched between two elastic films 4 existing in the window portions 3a and 3b, respectively. Then, put them in the outer box 1 1 as they are (Fig.

1 9 (b)). Alternatively, first, one packing material 1 is put in the outer box 1 1, and the objects to be packed 20 a are placed in the window portions 3 a and 3 b (the elastic film 4 is present here) of the packing material 1. And 20b, respectively, and then put another packing material 1 in the opposite direction to the packing material 1 put in the outer box, that is, its window portions 3a, 3b ( Here, the elastic film 4 may be placed in the outer box 11 in such a direction as to cover the packages 20a and 2Ob, respectively. In this way, the object to be packed is supported by the elastic film 4. When the lid of the outer box 11 is closed, and if necessary, it is closed with adhesive tape so that the lid is not opened, the package is completed.

Still another example of the packing method of the present invention includes the following method. First, for example, the packing material 1 shown in FIG. Next, the article 20 to be packed is placed on the window 3 (where the elastic film 4 is present) of the packing material 1 in the outer box 11. Next, the packing material 1 shown in FIG. 10 is placed thereon so that the elastic film 4 present in the window portion 3c covers the packaged object 20. Next, another packaged object 20 is placed on the elastic film 4 existing in the window 3d of the packing material 1 shown in FIG. Thereafter, the packing material 1 shown in FIG. 10 is used according to the number of the objects 20 to be packed. However, the last packing material 1 used is, for example, that shown in FIG. In this way, the plurality of packages 20 are successively supported by the elastic film 4,

11 Close the lid, and if necessary, stop the lid with an adhesive tape to prevent the lid from opening. This example is suitable when the product is composed of a plurality of different parts and all of those parts are packed in one outer box.

When using the support member 13 independent of the outer box, the object to be packed 20 is supported and packed as follows.

For example, when the support member 13 shown in FIG. 21 is used, two packing materials 1 shown in FIG. 21 (or a packing material 1 having two window portions 3 and the window portions 3 and 3 When folded at the bendable portion 6 between the notches, the notch portions 8 and 8 overlap and bend the packing material 1 having two notch portions as shown in FIG. Sandwich the pieces. The article to be packed 20 is sandwiched and supported by the elastic film 4 of the packing material 1. Next, the packaged material 20 and the packing material 1 (two pieces or one piece) sandwiching it are set as a set, and the support member 13 is cut into the notch 18, and the frame part 2 of the packing material 1 is formed. Insert two. After the predetermined number of packing materials 1 are inserted into the cuts 18 of the support member 13 in this way, the support member 13 is stored in the outer box 11. It is also possible to store a plurality of support members 13 in one outer box. Alternatively, the support member 13 may be stored in the outer box 11 in advance, and the packing material 1 may be inserted into the cutout 18 of the support member 13 arranged in the outer box.

The case where the support member 13 shown in FIG. 22 is used is the same as the case where the support member 13 shown in FIG. 21 is used.

When using the support members 13a and 13b shown in Fig. 23, pack them as follows. First, the support member 13 a is housed in the outer box 11. Next, two packing materials shown in Fig. 23 (or two packing materials 1 having two window portions 3 and bending at the foldable portion 6 between the window portions 3 and 3), As shown in Fig. 23, bend the packing material 1 that has two cutouts, as shown in Fig. 23), and sandwich one packaged object 20. The article to be packed 20 is sandwiched and supported by the elastic film 4 of the packing material 1. The packaged material 2 0—the packaging material 1 (two pieces or one piece) sandwiching it, as a set, the support member 1 3a cut into the cut 18, the frame part of the packing material 1 22 Insert the card. In this way, when the two frame portions 2 of the packing material 1 are inserted into the cuts 18 of the support member 13a, the other portions of the frame portion 2 of the packing material 1 (the support members 13a The part opposite to the part inserted into the notch 18) and the other support member 13b Match with depth of cut 18

The support members 13a shown in Fig. 24 are the same as those in Fig. 24 except that they can support a plurality of sets of 20 items to be packed and a pair of packing materials 1 (two pieces or one piece) sandwiching them. This is similar to that shown in FIG. Note that FIG. 24 does not show the support member 13b in FIG. 23, but in this example, similarly, two support members are used (13a and 13b). Therefore, packing can be performed in the same manner as described with reference to FIG.

The support member 13 shown in FIG. 25 has two support portions 16. The set of 20 to be packed and the packing material 1 (two pieces or one piece) sandwiching it is inserted into the cuts 18 and 18 of the two support parts 16 and 16 . In this example, one side of the frame portion 2 of the packaging material 1 is supported by the two support portions 16 and 16, so the other side opposite to the one side need not be supported by another support member. .

In the support member 13 shown in Fig. 26, the support portion 16 is composed of two side surfaces 15 and 15, and the slit between the side surfaces 15 and 15 has 20 to be packed. And a pair of packing materials 1 (two or one pair) sandwiching it. Also in this example, one side of the frame portion 2 of the packaging material 1 is sufficiently supported by the supporting portion 16, so that the other side opposite to the one side need not be supported by another supporting member.

The example shown in FIGS. 27 and 28 is still another embodiment of the packing method of the present invention. FIG. 27 is a schematic perspective view, and FIG. 28 is a front view showing a state after packing is completed.

In this example, after packing material 1 a is stored in outer box 1 1, packing material 20 is stored so that packing material la is supported by elastic film 4 and frame portion 2 of packing material la. Then, the packing material 1b is placed on the packing object 20 and the upper part of the packing object 20 is held by the elastic film 4 portion. Finally, the lid of the outer box 11 is closed, and the lid is fixed to the outer box body using an adhesive tape or the like, thereby completing the packing.

In addition, it is also possible to store the accessory parts of the article to be packed 20 in the space inside the outer box. The type of the elastic film used in the present invention is not particularly limited. However, when the packing material of the present invention is actually used for packing a product, the type of the elastic film is specified mainly depending on the weight of the article to be packed.

Specific examples of the raw material polymer for producing the elastic film used in the present invention and Examples include polyolefins such as polyethylene and polypropylene, vinyl polymers such as polyvinyl chloride, polyesters such as polyethylene terephthalate, cellulose ester polymers such as cellulose diacetate, nylon 6 and nylon Polymers that provide heat-resistant engineering plastic films, such as polyamides such as 66, and polyimides and polysulfones; and polyurethanes. Further, regenerated cellulose such as cellophane and viscose rayon can also be used. In short, any polymer can be used as long as it can be formed into a film by any known method.

As the raw materials other than the polymer, those generally used when processing a polymer into a film may be used.

The film used in the present invention preferably has the following mechanical properties.

1) Tensile strength: that having a approximately 1 to 28 kg / mm wide strong tensile over of ² film can be used. An example of a film having a tensile strength of about 1 kg / mm ² is a soft polyvinyl chloride film / polyethylene film. An example of a film having a tensile strength of about 28 kg / mm ² is a T-type polyethylene terephthalate film. For example, in the case of packing the computer and large appliances, used film, tensile strength from 14.0 to 24. Preferably having from 6 kg / mm ^2, the 17. 6~28. 1 kg / mm ² Are more preferred. In the case of a light product such as a jewel, a film having a tensile strength of about 1.1 to 4.3 kg / mm ² may be used.

2) burst strength: is the best one that does not destroy, usually, burst strength is used of about 50~ 80 kg / cm ^2.

These films may be manufactured by a known method, or may be used by selecting a suitable one from a variety of commercially available products. In addition, when selecting a film, considering the film thickness in addition to the mechanical characteristics described above, the range of choice is widened. That is, for example, when the object to be packed is heavy, the film thickness may be increased. In addition, by using two or more films, it is possible to obtain substantially the same effect as when the film thickness is increased, that is, to increase the film strength and the like. The elastic film does not necessarily have to be colorless and transparent, but if it is transparent, it is particularly good if it is colorless and transparent so that the packaged items can be checked when the lid of the outer box is opened.

The elastic film is attached to a frame portion of the plate material. The means for attaching the elastic film to the plate is not particularly limited, but generally, an adhesive selected in consideration of the material of the elastic film and the plate is used. Alternatively, the elastic film may be adhered by heating the outer peripheral portion and fusing it to the frame of the plate material.

The material of the plate on which the elastic film is to be attached is not particularly limited. The material is selected according to the material to be packed, like the elastic film. The material of the plate material may be limited depending on the shape of the packing material of the present invention described above. For example, if the packing material also has supporting feet and the supporting feet have a curved surface, and if the plate material and the supporting feet are made of the same material, the material of those materials will have a curved surface. Limited to those that can be formed.

Specific examples of the material of the plate material include papers such as cardboard and coated cardboard, plastics such as ABS resin, polystyrene, and polycarbonate, and metals such as wood, iron, and aluminum. In the case of a packaging box in which the packaging material and the outer box are combined, paper is the best material for the board.

Although the shape of the plate is not particularly limited, a square or a square is preferable in consideration of the convenience and minimization of space when storing the packing material using the packing material of the present invention in iTJiji. However, other shapes, such as a circle and a rhombus, may be preferred depending on the shape of the items to be packed.

The shape of the window portion provided in the plate material is generally the same as the shape of the plate material itself, but may be a different shape, for example, a circular window portion is provided in a square plate material.

The support foot is provided so as to be continuous or in contact with the frame portion and at right angles to the frame portion, or is configured to be bent at right angles to the frame portion. Since the supporting feet are usually manufactured integrally with the plate, the material is the same as that of the plate. However, the distance between the outer box and the frame part of the packing material, or when packing multiple items in one outer box, If the support legs must be made of a harder material, such as when the distance between the frame parts of the material is to be increased, the support legs can be made of a material different from the plate material. Further, for example, when the plate material and the supporting feet are made of cardboard, the supporting feet of the cardboard may be formed into a double structure by, for example, bending in order to increase the strength of the supporting feet.

The material of the outer box is not particularly limited. The example is the same as the specific example of the material of the plate material. When used repeatedly as a so-called returnable box, the material is preferably plastic or wood.

The items to be packed are not particularly limited. Various goods such as ceramics, glassware, fruits, jewelry, etc., such as various home appliances, tableware, etc. can be supported by the packing material of the present invention and packed by the packaging box of the present invention. .

As described above, the packing material of the present invention has the support feet, whereby the distance between the outer box and the frame portion of the packing material, or a plurality of objects to be packed in one outer box, This is not necessary if the packing material is suspended and the distance between the frame portions of the packing material that hangs each packaged object is sufficient and appropriate.However, does the packing material have supporting feet? Alternatively, if the frame has a continuous support foot on a part of the frame, but this is not sufficient, a support member is provided inside the outer box.

When two packing materials of the present invention are paired to sandwich one packaged object, the two packing materials are folded together, and one packing material is bent to form one packing material. When one packing object is sandwiched between the above, the packing material is supported by a support member provided inside the outer box. The support member is formed of, for example, a plate material having a slit having a width substantially the same as the thickness of the frame portion of the packing material (or two sheets when two pieces of the packing material are supported together). You. The length may be the same as that of the frame portion of the packing material, or may be a length that can support only the central portion of the frame portion, and furthermore, the edge portion of the frame portion. The length may be such that it can support two places. The width is the same as the maximum width of the supporting frame part.For example, in the case of a structure in which the package is supported horizontally, the width of the It is only necessary to have enough width to support the frame so that the package does not hang down vertically. The material of the support member is usually the same as the material of the outer box, but different from it. May be used.

Further, the support member may be independent from the outer box. When two packing materials of the present invention having no supporting feet are put into one set to sandwich one packaged object, the two packing materials are folded together and one packing material is bent. When one packing material is sandwiched between two packing materials, the packing material is sandwiched between the notches of the support member taken out of the outer box or stored in the outer box. At this time, if there is a notch in the packing material, a stronger support is realized by the combination of the notch and the notch.

In the packing method of the present invention, the object to be packed is supported by the elastic film affixed to the plate material of the packing material from above and below or from the left and right by the tension of the film. The article to be packed may be supported by a film having a plane parallel to the bottom surface of the outer box, or may be supported by a film having a plane perpendicular to the bottom surface of the outer box. In addition, one outer box may contain only one item to be packed, or a plurality of items to be packed.

If the package is heavy or has a complicated shape, a part of the package is supported by the packing material plate (frame part), and the package is elastically filmed. May be supported.

In conventional packaging, a large amount of cushioning material such as styrene foam and bubble wrap was required to protect the items to be packed. However, if the packaging material of the present invention is used, the elastic film performs a buffering function, so that these cushioning materials are unnecessary. Therefore, the workability during packing and unpacking is improved.

Further, when the packing material of the present invention is used, the packing form is simple and compact, so that the work time for packing and unpacking is reduced, and from this viewpoint, the workability is improved. Furthermore, space for transportation and storage can be saved.

Since the packing material and the packaging box of the present invention can be reused depending on the material, the present invention contributes to the reduction of garbage.

If the elastic film is transparent, especially colorless and transparent, the items to be packed can be easily checked by opening the outer box lid. Can be performed quickly. In the case where the packaging box of the present invention is formed by forming a packing material and an outer box into a body, the present invention also has an effect of greatly reducing the manufacturing cost of the packaging box.

In addition, when using the packaging material of the present invention that can store a plurality of items to be packed in one outer box, the packaging method can be simplified.
