Description

  The present invention relates to an article storage case, and more particularly to a technique suitable for storing and storing long articles and transporting articles as a returnable box.

For example, when a long article is transported, an article storage case formed in a size for storing the article is used. In this case, the conventional article storage case is formed of paper material such as corrugated cardboard because it can be manufactured inexpensively and easily, and when shipped to the destination with the article stored, The article is returned in an empty state after being taken out, and is used not only as a so-called return box but also for storing and storing the article.
In addition, plastic folding return boxes have been proposed for reasons such as saving storage space when not in use, improving transportation efficiency, and ensuring a certain level of strength, and the like. As the box, of the four side plates erected on the bottom plate, for example, a pair of claws is connected by a hinge to be a rotatable tilt plate, and the other opposing pair is divided into two and hinged to each other. It is known that it is combined and folded inward. In this configuration, a pair of side plates and a tilt plate are folded on a bottom plate (see Patent Document 1).
JP-A-5-319432

As described above, when a conventional returnable box is made of paper material such as cardboard, a certain level of strength can be secured, but when transported in a stacked state, the strength of the paper material is increased. When a load exceeding the load is applied, it often breaks, and when it is significant, it is weakened in strength only by the outbound transportation (so-called outbound flight), and damaged so that it cannot withstand the use of the return flight. In addition to the problem of being simply discarded as garbage, there is a problem that it is inferior in water resistance, thus reducing the transportation efficiency. There was a fear of inviting.
Further, in the plastic folding returnable box, in order to be able to fold the pair of side plates and the tilt plate on the bottom plate, it is necessary to process the plastic plate by various processes, There was a problem that the manufacturing cost was high.
On the other hand, injection molded products are produced in large quantities today, but many defective products are produced due to mistakes during molding. Such defective products are discarded as scrap, but the amount of discarded products is large and cannot be ignored.

  The present invention has been made in consideration of such circumstances, and can utilize a recycled (recycled) synthetic resin to store and store long articles, and has sufficient strength and water resistance. It is an object of the present invention to provide an article storage case that can be obtained and used as a returnable box and that has good transport efficiency and can be reduced in price.

In order to achieve the above object, the present invention proposes the following means.
The invention according to claim 1 is provided with a long member that is formed of a synthetic resin and has a U-shaped cross section with both side plates sandwiching the opening and a bottom plate mounted on both side plates. The bottom plate and the both side plates of the member are each provided with a wave-like portion formed by repeatedly indenting in the thickness direction and projecting outward, and the elongated member is the opening portion. When the two are stacked so as to face each other, a space for accommodating the article is formed inside.
Accordingly, the long member is formed of synthetic resin, and the bottom plate is provided with the corrugated portion, and the side plate is also provided with the corrugated portion, so that the rigidity of the long member itself can be ensured. Moreover, when the article storage case is formed by overlapping two long members, the corrugated portions provided on both side plates of one long member and the both side plates of the other long member Since the wavy portions provided on the two engage with each other, the strength of the article storage case can be increased, and the rigidity can be easily increased.
Further, since it is made of synthetic resin, the strength can be ensured even when the article storage case gets wet with water, and the water resistance of the article storage case itself can be ensured.
The invention according to claim 2 is the article storage case according to claim 1, characterized in that a bulging portion protruding outward is formed at a corner portion between the bottom plate and the both side plates.
Thereby, when the bulging portion is formed, when an article is stored in the long member, a space is generated between the bottom corner portion of the article and the corner portion between the bottom plate and the side plate of the long member. Therefore, the bottom corner portion of the article does not contact the bulging portion.
The invention according to claim 3 is the article storage case according to claim 1 or 2, wherein a confirmation window is formed on the bottom plate.
Thereby, even if the article is in a packed state, the color of the article stored from the confirmation window can be specified.

  According to the first aspect of the invention, since the article storage case is configured by superimposing the elongated members formed using recycled (recycled) synthetic resin, the elongated articles are stored and stored. In addition, sufficient strength can be obtained and the container can be used as a returnable box, and the transportation efficiency can be improved and the cost can be reduced.

  According to the second aspect of the present invention, the bulge portion creates a space between the bottom corner portion of the article and the corner portion between the bottom plate and the side plate of the elongated member, and the bottom corner portion of the article is the bulge portion. Therefore, the effect that the article is not damaged is obtained.

  According to the invention of claim 3, since the color of the article stored from the confirmation window can be specified, an effect that it can be easily specified is obtained.

In FIG. 1, a long member 11 is used for an article storage case 10 of this embodiment. The elongate member 11 has a bottom plate 12 and both side plates 13 and 14 formed upright at both ends of the bottom plate 12 and has a U-shaped cross section. An opening 15 is provided on the opposite side of the bottom plate 12 between the two.
Then, as shown in FIG. 2, two long members 11 are prepared, and the long members 11 and 11 are overlapped so that the openings 15 of the members 11 and 11 face each other in the vertical direction. The article storage case 10 is configured by defining a space portion 16 therein.

The long member 11 will be described in detail. The long member 11 is reused as a raw material after defective products during molding and those collected after the end of the product life, and is remolded by extrusion molding or the like. Thus, it is formed with a thin wall thickness, for example, a synthetic resin such as vinyl chloride or polypropylene. And as shown in FIG. 1, the corrugated part 17 and 18 are each provided in the bottom plate 12 and the both-sides boards 13 and 14 of the elongate member 11, respectively.
In the bottom plate 12, the wavy portion 17 is formed by alternately repeating indenting inward along the width direction of the bottom plate and projecting outward. In this case, the wavy portion 17 is formed so as to be symmetrical on both the left and right sides with the center C of the bottom plate 12 as the center.

  The corrugated portion 18 is formed by alternately repeating indenting and projecting outward in the side plates 13 and 14 along the height direction from top to bottom. In this case, the corrugated portion 18 of the side plate 13 and the corrugated portion 18 of the side plate 14 are symmetrical with respect to the center C.

  Then, when transporting an article (not shown) having a long shape, the long member 11 is overlapped in the vertical direction, that is, as shown in FIG. The member 11 has the opening 15 upward, and the other long member 11 overlaps the long member 11, 11 so that the other long member 11 faces the opening 15. Define.

Since the article storage case 10 of this embodiment is configured as described above, the handling thereof will be described below. Hereinafter, for convenience of explanation, the lower long member 11 is referred to as “long member 11A”, and the upper long member 11 is referred to as “long member 11B”.
When transporting a long article, first, as shown in FIG. 1, the bottom plate 12 of the long member 11A is turned down with the opening 15 facing upward, and the inside of the long member 11A. To store the goods. Next, as shown in FIG. 2, the long member 11 </ b> B is placed on the long member 11 </ b> A so that the openings 15 overlap each other.

In this case, for example, the long member 11A is inserted into the long member 11B so that the both side plates 13, 14 of the long member 11B are outside the both side plates 13, 14 of the long member 11A. When the space portion 16 is defined by the two long members 11A and 11B, the wavy portion 18 provided on the side wall 13 of the long member 11A and the long member 11B are formed. The wavy portions 18 provided on the side wall 14 engage with each other, and on the opposite side, the wavy portions 18 provided on the side wall 14 of the elongate member 11 and the side walls 13 of the elongate member 11B are provided. The wavy portions 18 are engaged with each other, and are held in a state of being overlapped with each other.
Moreover, it is comprised by adjusting the engagement position of the wavelike part 18 provided in the side wall 13 of the elongate member 11A, and the wavelike part 18 provided in the side wall part 11B of the elongate part member 11B. The height of the article storage case 10 can be adjusted.

  When the two elongate members 11A and 11B are overlapped in this way, at both ends in both length directions, as shown in FIG. 2, an open portion 19 that remains open is defined. Therefore, next, the opening 19 is closed. In this case, for example, as shown in FIG. 3, the remaining long member 11C is used and cut from the long member 11C with a width dimension corresponding to the open portion 19 (portion indicated by a chain line). Thus, the closing member 20 having the side plates 13a and 14a is formed.

  Thereafter, the both side plates 13a and 14a of the closing member 20 are inserted into the opening 19 as indicated by the arrow X shown in FIG. 4A, thereby opening the opening of the article storage case 10 as shown in FIG. 19 is blocked. In this way, the long members 11A and 11B are overlapped with each other, and after the opening 19 formed by the both is closed by the closing member 20, as shown in FIG. The article storage case 10 is packed by being fastened with the dressing 21.

After packing in this way, the article storage case 10 in that state is loaded on a vehicle such as a truck and transported to a destination. When the article storage case 10 is stacked up and down at the time of transportation, the wave-like portion 17 provided on the bottom plate 12 of the elongate member 11B in the lower article storage case 10 and the upper step are not shown. Since the corrugated portion 17 provided on the bottom plate 12 of the long member 11A in the article storage case 10 is engaged with each other, there is no possibility of collapse of the load.
Then, after being transported from the shipping source to the shipping destination, after the article is taken out at the shipping destination, the article storage case 10 is returned to the shipping source. At the time of the return, for example, as shown in FIG. 6, it is transported and returned in a form in which the bottom plate 12 of the long member 11B is inserted into the long member 11A. In this case, since the elongate member 11B is inserted into the elongate member 11A, there is no fear of being bulky, and it does not take up a storage place during transportation.

In the article storage case 10 having the above-described configuration, the long member 11 is formed of synthetic resin, the corrugated portion 17 is provided on the bottom plate 12, and the corrugated portion 18 is provided on the side plates 13 and 14. The rigidity of the member itself can be ensured. Moreover, when the article storage case 10 is formed by overlapping two U-shaped long members 11 </ b> A and 11 </ b> B, the corrugated portions 18 provided on the side plates 13 and 14 of the long member 11 and Since the corrugated portions 18 provided on the side plates 13 and 14 of the long member 11B are engaged with each other, the strength of the article storage case 10 can be increased, and the rigidity can be easily increased.
Such an article storage case 10 does not become a completely airtight state, and can also ensure air permeability.

Therefore, according to the article storage case 10 of this embodiment, compared with the prior art in which the article storage case is formed of a paper material such as cardboard, the strength can be sufficiently satisfied and it can be effectively used as a returnable box. be able to.
In addition, synthetic resin must be diverted to other uses because it is difficult to obtain the original physical properties through a molding history, and eventually it must be discarded. By reusing as Case 10, resources can be used effectively.
Furthermore, since the article storage case 10 is configured using a synthetic resin product that has been discarded, the cost of the article storage case 10 can be reduced, and the article storage case 10 is configured by a synthetic resin. Therefore, the water resistance of the constructed article storage case 10 itself can be ensured.

7 and 8 show an article storage case according to a second embodiment of the present invention.
This embodiment is different from the first embodiment in that a bulging portion 22 is provided on the long member 11 as shown in FIG.
That is, the bulging portion 22 is formed to bulge outwardly between the bottom plate 12 and the side plates 13 and 14 of the long member 11. In this case, when the article is stored in the elongated member 11, the bulging portion 22 bulges laterally so as not to contact the bottom corner C of the article.

Thus, when the bulging part 22 is formed in the elongate member 11, when the article | item B is accommodated in this elongate member 11, as shown in FIG. Since a space is generated between the bottom plate 12 of the elongated member 11 and the corner portion between the side plates 13 and 14, the bottom corner portion C of the article B does not contact the bulging portion 22.
Thus, the article B can be stored without damaging the bottom corner C, and the reliability of the article storage case 10 can be improved.

FIG. 9 shows an article storage case according to the third embodiment of the present invention.
According to this embodiment, since the article B stored from the confirmation window 23 can be confirmed even when the article B is packed, the article B stored before transportation can be confirmed. Therefore, it is possible to prevent the contents from being mistakenly transported, and the transported article B can be easily confirmed at the transport destination.
This is true not only when transporting in a returnable box but also when storing and storing the article B.

    Furthermore, although the example in which the confirmation window 23 is provided on the bottom plate 12 is shown, it may be provided on either one of the side walls 13 and 14. However, in this case, when the article storage case 10 is formed by overlapping two long members, the confirmation window 23 needs to be formed at a position where the long members 11A and 11B face each other.

  In the illustrated embodiment, when the two long members 11A and 11B are overlapped with each other, the example in which the long member 11A is inserted into the long member 11B is shown. However, for example, when an article having a low height is stored, the side plate 14 of the long member 11B is long inside the side plate 13 of the long member 11A, and the outside is long outside the side plate 14 of the long member 11A. The side plates 13 of the scale member 11B may be used so as to be in contact with each other.
