Description

Technical Field

[0001] The present invention relates to an article storage box that can be used as a storage box for parcel delivery that can temporarily store parcels to be delivered, for example, beside the entrance, or as a passing box that can be repeatedly used for delivering various products to stores and the like and being returned after the products are taken out.

Background Art

[0002] Conventionally, for example, when the consignee is absent and direct delivery of various parcels cannot be made, the parcels may be taken home once and redelivered. However, such redelivery is a great burden on the delivery company, so so-called leave-at-door delivery is often carried out, where the parcels are left as they are, for example, beside the entrance so that the consignee can pick them up even at a later time.

[0003] However, in such leave-at-door delivery, the parcels may be stolen or lost before the consignee confirms and picks them up, and there is a risk that the safety of the parcels and the certainty and stability of delivery implementation cannot be fully ensured. Therefore, collective boxes with multiple storage rooms arranged, various storage boxes placed beside individual entrances, etc. have been proposed.

[0004] In particular, for home delivery to individual residences such as detached houses and apartment houses without collective boxes, receiving and storage facilities are provided individually beside each entrance. For example, the receiving boxes described in Patent Document 1 and Patent Document 2 have been proposed. The parcel delivery receiving box and its installation method according to Patent Document 1 are configured to store a weight in a storage space provided at the bottom of a lockable storage box body as a measure against theft. The parcel delivery receiving box according to Patent Document 2 is provided with a triangular roof-shaped lid portion having a foldable configuration that can be opened and closed on the upper part of a deployable and assemblable receiving box.

[0005] However, in order to ensure complete anti-theft measures, the home delivery box according to Patent Document 1 is made of a rigid material so that the storage box itself is not easily damaged, and has a fixed installation structure that makes it difficult to move, or forms a storage space for weights. As a result, it inevitably becomes relatively expensive. Since the upper part of the home delivery box according to Patent Document 2 has a triangular roof shape, it cannot be stacked in multiple stages, and it is not possible to place luggage on the upper surface even temporarily.

[0006] In addition, the home delivery boxes of these Patent Document 1 and Patent Document 2 can only be used to receive home deliveries. Even if they can easily store and keep luggage, for example, it is difficult to use them as so-called reusable passing boxes that are repeatedly used as storage containers when transporting products and semi-finished products between enterprises and factories. Their uses are limited.

Summary of the Invention

Problems to be Solved by the Invention

[0008] Therefore, the present invention was created in view of the above-mentioned existing circumstances. For example, it can be used as a home delivery box that can temporarily store and keep various home-delivered goods when they are so-called left at the door, or as a reusable passing box for transporting various goods. When not in use, it can be easily folded, and when unfolded and assembled, it maintains a box shape, has excellent stability, not only reliably protects the stored items, but also provides an article storage box that is easy to stack in multiple stages.

Means for Solving the Problems

[0009] In order to solve the above problems, in the present invention, the front and rear side walls 4 and 5 and the left and right side walls 6 and 7 standing on the side edges of the foldable bottom wall 2 are foldably connected, and the left and right side walls 6 and 7 themselves or the front and rear side walls 4 and 5 themselves are formed to be foldable in a double-fold manner, and a storage box body 1 is formed. A bottom reinforcing plate 3 is connected to the bottom wall 2 so as to be able to rise and fall, and a closing lid body 10 is provided to open and close the opening of the storage box body 1. The closing lid body 10 is provided with a pair of opening and closing lids 11 that cover the opening from the upper edge of either one of the front and rear side walls 4 and 5 and the left and right side walls 6 and 7, and is folded from the upper edge of the other one under the lower surface of the opening and closing lid 11, and is provided with a folding lid 15 that is joined to the opening and closing lid 11 by a joining means 20 and is disposed substantially parallel to the bottom wall 2 at the opening surface position. The opening and closing lid 11 can be configured to have a shape and size that cover approximately half of the front and rear or left and right of the opening of the storage box body 1. The folding lid 15 is configured such that the left and right side edges of the folding lid 15 are foldably continuous with the left and right side edges of the front and rear opening and closing lids 11, and when the storage box body 1 is opened, it stands up together with the opening and closing lid 11, and the whole of the storage box body 1 can be configured to exhibit a tubular shape with an upper opening. The folding lid 15 is provided with a lid folding line 16 that is continuous with a side wall folding line 8 that folds the front and rear side walls 4 and 5 or the left and right side walls 6 and 7 inward of the storage box body 1, and folds the folding lid 15 itself inward of the storage box body 1. A folding line 18 is provided in the folding fixing portion 17 partitioned into front and rear or left and right by this lid folding line 16, and the folding fixing portion 17 is folded in a triangular shape so as to fold the folding fixing portion 17 itself inward of the storage box body 1 between the upper edge end of the corner portion of the storage box body 1 and the upper end of the lid folding line 16. The joining means 20 can be configured to join the opening and closing lid 11 and the folding lid 15 superposed on the lower surface of the opening and closing lid 11, and to join them by any one of a magnet, a hook-and-loop fastener, and a snap button on the abutting surface for joining. A superimposed lid body 25 is connected to the upper edge of one of the opening and closing lids 11 so as to be able to rise and fall, and this superimposed lid body 25 can be configured to cover and lock the other opening and closing lid 11.

[0010] In the article storage box according to the present invention configured as described above, when assembled by spreading the storage box body 1 and overlapping and laying down the bottom reinforcement plate 3 on the bottom wall 2, various articles can be stored inside the storage box body 1. After storage, the folding lid 15 is folded by folding the opening and closing lid 11 of the closing lid 10, the storage box body 1 is closed, and the articles are stored and protected. The bottom reinforcement plate 3 is overlapped on the foldable bottom wall 2 to reinforce the bottom and maintain the open state of the storage box body 1. By standing it up, the storage box body 1 can be folded flat while being stored inside the storage box body 1. As the opening and closing lid 11 at the upper part of the storage box body 1 opened in a cylindrical shape folds to close the opening, the folding lid 15 continuously arranged between the opening and closing lids 11 is folded inward of the storage box body 1 by the lid folding line 16 and is arranged on the lower surface of the opening and closing lid 11. When arranged, the entire folding lid 15 is held at the opening of the storage box body 1 by being joined and held to the opening and closing lid 11 by the joining means 20, and the opening of the storage box body 1 is closed together with the opening and closing lid 11 without falling inward of the storage box body 1. Each of the opening and closing lids 11 covers approximately half of the opening of the storage box body 1, so that together they cover almost the entire area of the opening. Combined with the fact that the folding lid 15 is folded on the lower surface of the opening and closing lid 11, for example, fingers or others cannot penetrate from the side of the mating part between the opening and closing lids 11, and the stored articles are safely protected. Moreover, the entire area of the folding lid 15 joined by the joining means 20 is more reliably held and does not fall inward of the storage box body 1. The overlapping lid body 25 is overlapped and locked to the other opening and closing lid 11 in a state of being continuously provided from the upper end edge of one opening and closing lid 11 after the storage box body 1 is closed by the opening and closing lid 11, thereby maintaining the opening and closing lid 11 in a state where it cannot be opened upright and protecting the articles stored in the storage box body 1. By overlapping the overlapping lid body 25 on the opening and closing lid 11, the storage box body 1 can be assembled and used in a state having a flat upper surface and can be stacked in multiple stages so that a plurality of them can be used together, for example, enabling loading on a freight car. Also, when not in use, by standing and opening the opening / closing lid 11, the folding lid 15 also stands and opens following it. The left and right side walls 6, 7 or the front and rear side walls 4, 5 and the folding lid 15 are folded into the storage box body 1 by the side wall folding line 8 and the lid folding line 16 continuous with this side wall folding line 8, and together with the bottom reinforcing plate 3 that is stood up, the whole is folded flat to make it compact.

Effects of the Invention

[0011] Since the present invention is configured as described above, in the storage box body 1 that is open and assembled, by folding and tucking the opening / closing lid 11 inwardly into the storage box body 1 and closing the storage box body 1 by folding, the stored articles can be protected. Conversely, by standing and opening the opening / closing lid 11, the front and rear side walls 4, 5, the left and right side walls 6, 7, and the folding lid 15 can be folded compactly and stored.

[0012] That is, in the present invention, it is composed of a storage box body 1 in which the front and rear side walls 4, 5 and the left and right side walls 6, 7 standing on the bottom wall 2 to which the bottom reinforcing plate 3 is connected so as to be able to freely rise and fall are foldable, and a closing lid body 10 that closes the opening of the storage box body 1 in an openable and closable manner. The closing lid body 10 is provided with a pair of opening / closing lids 11 that cover the opening from the upper edge of either one of the front and rear side walls 4, 5 and the left and right side walls 6, 7, and is folded from the upper edge of the other one on the lower surface of the opening / closing lid 11, and is provided with a folding lid 15 that is joined to the opening / closing lid 11 by a joining means 20 on the lower surface of the opening / closing lid 11 and is arranged substantially parallel to the bottom wall 2 at the opening surface position. Thus, by the closing and folding of the opening / closing lid 11 and the folding and standing of the folding lid 15 following the opening and standing of the opening / closing lid 11, in the storage box body 1, it is possible to achieve the safety of storage while maintaining closure during article storage and the compact storage property when not in use.

[0013] Further, the folding lid 15 is provided with a lid folding line 16 for folding the folding lid 15 itself, which is continuous with the side wall folding line 8 for folding the front and rear side walls 4, 5 or the left and right side walls 6, 7. A folding line 18 for folding the folding fastening portion 17 itself into the inner side of the storage box body 1 is provided in the folding fastening portion 17 partitioned by the lid folding line 16 into front and rear or left and right. Since the folding lid 15 is continuous with the opening / closing lid 11 and follows the standing open and lying down closed states of the opening / closing lid 11, the storage box body 1 can be closed and opened only by operating the opening / closing lid 11 to rise and fall, and the handling is easy.

[0014] When the storage box body 1 is folded to be closed by the opening / closing lid 11, the folding lid 15 is superposed on the lower surface of the opening / closing lid 11. When superposed, the folding lid 15 is held in a state of being joined to the opening / closing lid 11 by the joining means 20 provided between the opening / closing lid 11 and the folding lid 15. Therefore, combined with the fact that the connecting portion of the folding lid 15 with the opening / closing lid 11 is folded into a triangular shape in the folding lid 15 itself, the folding lid 15 does not fall into the inner side of the storage box body 1, does not damage the articles stored inside the storage box body 1, and does not reduce its internal volume.

[0015] The opening / closing lid 11 is shaped and sized to cover approximately half of the front and rear or left and right of the opening of the storage box body 1. Combined with the fact that the folding lid 15 is folded and arranged on the lower surface of the opening / closing lid 11, it can prevent fingers or other objects from entering the storage box body 1 from the side such as the joining portion of the opening / closing lid 11. Therefore, it is impossible to take out the stored articles from the outside or play pranks, not only is the safety during storage not impaired, but also the folding lid 15 does not fall into the storage box body 1, and rainwater etc. will not penetrate even when placed outdoors.

[0016] When the stacking lid 25 is overlapped on the opening / closing lid 11 that closes the storage box body 1 together with the folding lid 15, the upper surface of the storage box body 1 becomes flat with the upper surface itself being reinforced, enabling multi-stage stacking. For example, a large number of them can be loaded on a freight car, and since the storage box body 1 can be made of a lightweight material, it does not take up much space in terms of weight and can be used for efficient transportation and handling.

[0017] In addition, the reference numerals appended to each of the sections on the means for solving the above problems and the effects of the invention are provided to facilitate reference to the portions showing each component of the configuration described in the drawings. The present invention is not limited to the structures, shapes, etc. shown by these descriptions, reference numerals in the drawings, etc.

Embodiments for Carrying out the Invention

[0019] Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a foldable storage box body, which is formed into a bottomed cylindrical shape by connecting rigid front and rear side walls 4 and 5 and left and right side walls 6 and 7 standing on the sides of a rectangular bottom wall 2 made of a foldable sheet material. The left and right side walls 6 and 7 themselves or the front and rear side walls 4 and 5 themselves are foldable in a double-fold manner inside the storage box body 1 and are flattened when folded.

[0020] And on the bottom wall 2, a rigid bottom reinforcing plate 3 placed on the inner surface of the bottom wall 2 is connected to the side of the bottom wall 2, for example, at the bottom of the rear side wall 5 so as to be able to rise and fall. As will be described later, as the front and rear side walls 4 and 5 are folded and stand up so as to contact the inner surfaces of the front and rear side walls 4 and 5, the bottom wall 2, for example, the central part of the bottom wall 2 itself is pulled up and folded into the storage box body 1, making it foldable (see FIG. 7).

[0021] At the opening of this storage box body 1, there is a closing lid body 10 that is connected to the upper edges of the left and right side walls 6 and 7 and the front and rear side walls 4 and 5 so as to be able to rise and fall. When the storage box body 1 is opened, it stands up upward along the wall surfaces of the left and right side walls 6 and 7 and the front and rear side walls 4 and 5, and when the storage box body 1 is closed, it is folded to close the opening of the storage box body 1 in a substantially flat shape.

[0022] In the drawing, the left and right side walls 6 and 7 can be folded into the storage box body 1 to be reduced along the front-rear direction, and the front and rear side walls 4 and 5 are folded with the bottom reinforcing plate 3 sandwiched therebetween. A side wall folding line 8 is provided at a substantially central position at a position approximately 1 / 2 along the front-rear direction. Of course, although not shown, the front and rear side walls 4 and 5 may be foldable, and it is not limited to adopting any of these. In the present embodiment, an example in which the left and right side walls 6 and 7 are folded will be described.

[0023] Each member piece described later in the bottom reinforcing plate 3, front and rear side walls 4, 5, left and right side walls 6, 7, and closing lid 10 is formed by covering and wrapping, for example, the front and back of a plate-shaped material made of a hard synthetic resin material with a sheet made of a synthetic resin material with an appropriate thickness as appropriate. The connecting parts between these are made foldable, foldable in, and undulating by the folding action of the sheet material itself.

[0024] The closing lid 10 is provided with a pair of opening and closing lids 11 that cover approximately 1 / 2 of the opening from the upper edge of either one of the front and rear side walls 4, 5 and the left and right side walls 6, 7, and a folding lid 15 that is folded from the upper edge of the other one and joined to the opening and closing lid 11 by a joining means 20 described later on the lower surface of the opening and closing lid 11 and is arranged substantially parallel to the bottom wall 2 at the opening surface position.

[0025] In the drawing, the opening and closing lid 11 is continuously provided on the upper edges of the front and rear side walls 4, 5 so as to be undulating, and the folding lid 15 is provided on the upper edges of the left and right side walls 6, 7 for explanation. However, there may also be a case where the opening and closing lid 11 is provided on the upper edges of the left and right side walls 6, 7 and the folding lid 15 is provided on the upper edges of the front and rear side walls 4, 5. Which one to adopt is not particularly limited. In the present embodiment, an example where the opening and closing lid 11 is continuously provided on the upper edges of the front and rear side walls 4, 5 so as to be opened and closed in the front and rear directions will be described.

[0026] Each of the front and rear opening and closing lids 11 is formed in a size and shape that covers approximately 1 / 2 of the front and rear of the opening of the storage box body 1. When lying down to cover the opening, they are arranged to cover the entire area of the opening together. Of course, even if this opening and closing lid 11 has a width less than 1 / 2 of the depth length of the storage box body 1 in the front and rear directions, it can cover the entire area of the opening of the storage box body 1 by being covered by an overlapping lid 25 described later.

[0027] The left and right folding lids 15 provided at the upper edges of the left and right side walls 6 and 7 are such that the left and right side edges of the folding lids 15 are foldably and continuously connected to the left and right side edges of the front and rear opening and closing lids 11 continuously provided at the upper edges of the front and rear side walls 4 and 5. When the storage box body 1 is opened, they stand up together with the opening and closing lids 11, and the whole storage box body 1 is in the shape of a cylinder with an upper opening.

[0028] This folding lid 15 is continuously provided with a lid folding line 16 for folding the folding lid 15 itself inward of the storage box body 1, which is continuous with the side wall folding line 8 for folding the left and right side walls 6 and 7 inward of the storage box body 1. And in the folding fixing part 17 partitioned front and rear by this lid folding line 16, a folding line 18 is provided for folding the folding fixing part 17 itself inward of the storage box body 1 in a triangular shape between the upper edge end of the corner part of the storage box body 1 and the upper end of the lid folding line 16.

[0029] The front and rear opening and closing lids 11 and the left and right folding lids 15 are connected around the upper part of the storage box body 1 and are in a cylindrical shape as a whole. And when the opening and closing lid 11 is laid down inward of the storage box body 1 so as to close the opening of the storage box body 1, the folding lids 15 continuous at the left and right side edges of the opening and closing lid 11 are also folded inward at the upper part of the storage box body 1 by the folding line 18 together with the opening and closing lid 11. The folded folding lid 15 is located inside the opening and closing lid 11, that is, on the lower surface of the opening and closing lid 11. The folded folding lid 15 is such that a portion (b) presenting a triangular shape continuous with the front and rear opening and closing lids 11 outside the folding line 18 is superposed on the upper surface of a portion (a) presenting a triangular shape continuous with the upper edges of the left and right side walls 6 and 7 inside the folding line 18 as shown in FIG. 7 (see FIG. 6).

[0030] Between the opening and closing lid 11 and the folding lid 15 superposed on the lower surface of this opening and closing lid 11, a joining means 20 for joining the opening and closing lid 11 and the folding lid 15 is provided. By this joining means 20, the opening and closing lid 11 and the folding lid 15 are regulated to be substantially parallel to the bottom wall 2 of the storage box body 1 so as not to fall inward of the storage box body 1 together and stay at the upper opening position of the storage box body 1.

[0031] If the folding lid 15 falls inside the storage box body 1, for example, when placed outdoors, rainwater or the like may run down the surface of the folding lid 15 and drip into the storage box body 1. As described above, by restricting the folding lid 15 together with the opening / closing lid 11 to the opening position of the storage box body 1, such a situation can be prevented, and there is no risk of soiling the stored items.

[0032] This joining means 20 is provided with joining tools such as magnets, hook-and-loop fasteners, or snap buttons at the parts where the opening / closing lid 11 and the folding lid 15 directly contact, for example, at the upper parts of the left and right side edges of the opening / closing lid 11, at the triangular parts continuous with the opening / closing lid 11 on the folding lid 15, especially at the corner parts thereof, for example, at the parts presenting a triangular shape continuous with the opening / closing lid 11 shown in (b) above. The built-in structure of the magnet can be joined by bringing the opening / closing lid 11 and the folding lid 15 into contact with each other, and can be separated so as to be peeled off by a semi-forced opening operation when opening the storage box body 1, which is very convenient.

[0033] After closing the opening of the storage box body 1 with the opening / closing lid 11, a stacking lid body 25 for locking the opening of the storage box body 1 is continuously provided so as to be able to rise and fall, for example, from the upper end edge of the rear opening / closing lid 11. This stacking lid body 25 is formed by continuously and freely connecting a front covering piece 27 that can rise and fall to a lid body main body 26 covering the front opening / closing lid 11 and is superposed on the upper part of the front side wall 4. Then, by connecting the locking loops 28 provided respectively at the continuous part of the front covering piece 27 on the inner side surface of this stacking lid body 25 and the upper end edge of the front side wall 4 so that they can be locked, for example, by a lock K, it is possible to prevent unauthorized opening by others. Reference numeral 29 in the figure is a fixing tool such as a hook-and-loop fastener for fixing the stacking lid body 25 to the upper surface of the opening / closing lid 11.

[0034] Also, although not shown in the figure, by joining the front covering piece 27 of this stacking lid body 25 to the side surfaces of the front and rear side walls 4, 5 or the left and right side walls 6, 7 with, for example, magnets or hook-and-loop fasteners, especially when used as a through box, consideration is given so that the front covering piece 27 of the stacking lid body 25 does not protrude when closed, and the outer dimensions can be reduced.

[0035] Also, by inserting, for example, a wire, a belt, etc. through the lock loops 22 provided on the left and right side edges of the rear side wall 5 and fixing it to other suitable fixtures such as gateposts, fences, etc., it can be used to prevent theft of the storage box itself.

[0036] On the outer surfaces of the left and right side walls 6 and 7, there are attached handles 23 formed by fixing the ends of, for example, strip materials, which can be used for carrying, moving, etc. of the storage box itself. Also, insertion loops 24 are arranged symmetrically on the left and right of the outer surfaces of the left and right side walls 6 and 7. As shown in FIG. 9, by inserting and fixing a belt B, etc. through the insertion loops 24 of each storage box stacked in multiple layers, for example, it is possible to prevent the collapse of the load during stacking.

[0037] Also, reference numeral 30 in the figure is a binding belt that wraps around and bundles the whole to maintain the folded state when the storage box body 1 is folded when not in use, and is attached to, for example, the front covering piece 27.

[0038] Although not shown, a flexible gasket portion can also be provided between each of the front and rear side walls 4 and 5, and the left and right side walls 6 and 7, and the opening and closing lid 11 and the folding lid 15. With this gasket portion, after folding the entire storage box body 1, the opening and closing lid 11 and the folding lid 15 can be overlapped with respect to the front and rear side walls 4 and 5 and the left and right side walls 6 and 7 to enable folding. Then, after folding and overlapping, it becomes almost the same height as the storage box body 1, and multiple storage boxes can be stored in one storage box according to the present invention. For example, when returning it as a passing box, it can be bundled and becomes compact, which is convenient.

[0039] Next, an example of use in the embodiment described above will be described. From the folded state, separate the front and rear side walls 4 and 5 and expand the bottom wall 2, and lay down the bottom reinforcement plate 3 and overlap it on the bottom wall 2. Then, the storage box body 1 becomes a box shape with an upper open structure. After that, lay down the front and rear opening and closing lids 11 to close the opening, and close it with the overlapping lid body 25.

[0040] When the opening / closing lid 11 is folded down so as to be laid down, the left and right folding lids 15 that are continuous between the front and rear opening / closing lids 11 follow and are folded inward of the storage box body 1, and the joining means 20 joins and holds the folding lid 15 that is folded on the lower surface of the opening / closing lid 11. Therefore, the opening / closing lid 1 and the folding lid 15 are in an overlapping state, stay at the opening of the storage box body 1, do not fall into the storage box body 1, maintain the storage volume in the storage box body 1 as it is, and do not get in the way when storing articles.

[0041] And for example, when it is used for receiving home delivery, it is installed at the receiving place and, if necessary, anti-theft measures are taken. When delivering the home delivery by a home delivery company, the overlapping lid 25 and the opening / closing lid 11 are opened, the home delivery item is stored in the storage box body 1, the opening / closing lid 11 is closed and the overlapping lid 25 is overlapped, and it is locked with the lock K. Then, the recipient can unlock the lock K and take out the home delivery item.

[0042] Also, after assembly, for example, it can be carried by the handle 23 and can also be used as a so-called passing box for transporting goods to a store or transporting various members and parts to a factory or the like.

[0043] When the opening of the storage box body 1 is closed by the overlapping lid 25 after assembly, since the top plate portion is substantially flat, it can also be stacked as shown in FIG. 9. When stacking, by inserting and fixing a belt B or the like into the insertion loops 24 provided on the left and right side walls 6 and 7, it is possible to prevent the load from collapsing, and it can be loaded on a cargo vehicle or the like in a stacked and bundled state, and a large number of transports are also possible.

[0044] Note that when not in use, it can be folded. The overlapping lid 25 is laid down on the rear side wall 5 side, and the opening / closing lid 11 is erected. By the erection and opening of the opening / closing lid 11, the joining by the joining means 20 is semi-forcibly released and the folding lid 15 is also opened upward. Next, the bottom reinforcing plate 3 is erected and lifted, and the left and right side walls 6 and 7 are folded inward of the storage box body 1 so as to fold the bottom wall 2. It can be held flat by surrounding it with the binding belt 30 of the front covering piece 27, and can be stored compactly and bundled.
