BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation device,
In particular, it relates to a transportation device for transporting seafood, fresh vegetables and the like.

[0002]

2. Description of the Related Art As is well known, when fresh fish, seafood and the like are transported, they have traditionally been placed in wooden boxes for transportation. Since this wooden box is almost standardized, it can be stacked and transported to other markets, and can be recycled well. On the other hand, in recent years, containers made of foamed polystyrene, which have good heat retention and are lightweight, have been widely used.

[0003]

However, since the wooden box uses wood, it has poor durability, is troublesome to clean and handle, and has a sanitary problem. Also,
There was also a problem with heat retention, and there was also a problem with consuming a large amount of forest resources. On the other hand, the polystyrene container is a source of dust because it is disposable. Moreover, it is a big problem because it is difficult to process the foamed polystyrene. Also, the polystyrene foam is lightweight,
It is bulky and requires a certain amount of thickness to obtain the desired strength. Therefore, a large amount of space is required not only for transportation but also for storage, and there is a problem in effective use of the space. The present invention has been proposed in view of the above, and while keeping the respective advantages of the wooden box and the foam styrene container, while suppressing the generation of dust to the minimum, it can be reused for a longer period of time. The purpose is to provide a device.

[0004]

In order to achieve the above object, the present invention provides a synthetic resin outer frame that can be used repeatedly.
It consists of a disposable paper inner box and lid, and the outer frame is a nearly rectangular bottomless frame consisting of a pair of horizontal and vertical bars facing each other. The middle box is a water-resistant paper-made assembly container that is provided with a locking step portion that receives the boxes and is provided with an engaging means that connects the upper and lower frames to each other in a stacked state so that the boxes can be stacked. , The top surface is open, and has a locking edge around the opening, and the lid has standing pieces with a low height on the four sides of the top plate, and the assembled inner box is stored in the outer frame. At the same time, the lid is attached to the opening of the inner box, and the locking edge of the inner box is locked to the locking step of the outer frame so that the inner box is protected by the outer frame.

[0005]

[Function] By attaching and surrounding the inner box without joints or breaks in the outer frame which is a frame body made of synthetic resin, the inner box can be protected. Further, the inner box can be stored in the expanded state. On the other hand, since the outer frame has a heat insulating effect, it is possible to maintain the freshness of the fresh food products and the like stored in the inner box, and also has strength so that the inner box is protected. Moreover, since the outer frame can be reused and the inner box uses recycled resources, it can contribute to effective use of resources and environmental conservation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to an embodiment shown in FIG. 1. FIG. 1 is a perspective view showing the outline of a transportation apparatus 1 according to the present invention.

That is, the outline of the transportation apparatus 1 according to the present invention is composed of a synthetic resin outer frame 2 that can be repeatedly used, a disposable paper inner box 3 and a lid 4, and the outer frame. Two
Is a substantially rectangular bottomless frame body composed of a pair of horizontal rails 5a and vertical rails 5b which face each other. Locking step portions 6 for receiving the inner box 3 are provided on the upper and lower end surfaces, and the stacked state is obtained. At this time, engaging means 7 for connecting the upper and lower outer frames 2 to each other is provided to enable stacking, and the inner box 3 is a paper-made container having water resistance, and the upper surface is opened and A locking edge portion 11 is formed around the lid body 4, and the lid body 4 is provided with standing pieces 13 having a low height on four sides of the top plate portion 12, and the assembled middle box 3
Is housed in the outer frame 2, the lid 4 is attached to the opening of the inner box 3, and the locking edge portion 11 of the inner box 3 is locked to the locking step 6 of the outer frame 2 to secure the inner box 3 Is protected by the outer frame 2.

More specifically, the outer frame 2 has a pair of horizontal rails 5a facing each other and a pair of vertical rails 5 facing each other.
It is a frame body made of b and having no bottom. Further, the outer frame 2 is symmetrical with respect to any direction. That is, it is formed so as to be symmetrical with respect to the center line in each direction such as up and down, left and right, front and back. Therefore, they can be stacked or lined up in any orientation.

Further, each of the horizontal rails 5a and the vertical rails 5b constituting the outer frame 2 is formed in a hollow shape and has a so-called barrel-shaped cross-sectional shape having a bulge in the central portion in the height direction. . Furthermore, a concave portion 14 is formed on the inner side surface of the outer frame 2 to obtain a reinforcing effect. The recessed portion 14 can be changed in design. Further, the recessed portion 14 is also formed inside the corner portion which is a connecting portion of the crosspieces 5 ...

On the other hand, the inner surface of each of the crosspieces 5 is vertically symmetrically provided with an inclination corresponding to the inclination of the side surface portion 9 so that the side surface portion 9 of the inner box 3 described later follows. ).

A locking step 6 is provided on the upper end surface of the outer frame 2 (which becomes the lower end surface when inverted). The locking step portion 6 is formed by bulging the outer portion of the upper end surface 15 of each crosspiece 5 ... Or vice versa. For example, in the illustrated embodiment, an L-shaped raised portion 16 having a corner portion as a base point is formed along the outer edge of the upper end surface 15 so that the inner portion of the raised portion 16 serves as the locking step portion 6. There is. As shown in FIG. 2, for example, the raised portion 16 is interrupted at the central portion in the lengthwise direction of each of the crosspieces 5 ... .

Further, the upper end surface 15 provided on each crosspiece 5, ... According to the illustrated embodiment, the upper end surface of the raised portion 16 has an opposite phase at the facing position and an opposite phase at the upper and lower positions. The engaging means 7 is provided. The engaging means 7 is formed along, for example, the ribs 17a and 17b formed along the horizontal rail 5a and the vertical rail 5b.
a, 18b, and when the outer frame 2 is stacked, the projecting pieces 17a, 17b and 18a, 1 of the outer frame 2 that are vertically adjacent to each other.
8b are engaged with each other to prevent misalignment. The protrusions 17a and 18a are located outside, and the protrusions 17b and 18b are located inside.

The outer surface of the outer frame 2 is inclined so as to be slightly narrowed toward the upper and lower ends, leaving a flat portion 19 approximately in the middle in the height direction. For this reason, when the outer frame 2 is placed upright, the stability is lowered, so that the outer frame 2 is not placed in this state, which helps prevent damage. The outermost portion is the flat portion 1
Therefore, when placed side by side, the outer frames 2 adjacent to each other come into close contact with each other.

On the other hand, in the middle of the length of each of the crosspieces 5 ..., A clue portion 20 slightly recessed with the flat portion 19 left.
a and 20b are formed. That is, this clue 20 is
This is to make it easy to hang hands and lift. Further, according to the illustrated embodiment, the cue portion 20b of the vertical rail 5b, which is the short side, is inserted to the middle of the locking step portion 6. Thereby, even when the locking box 6 of the outer frame 2 and the locking edge 11 of the middle box 3 are in close contact with each other when the middle box 3 described later is mounted in the outer frame 2, the middle box 3 When pulling out, the fingers can be hooked on the locking edge 11 of the middle box 3.

The outer frame 2 having the above-mentioned structure is integrally molded of synthetic resin. If this synthetic resin is used as a single material, it can be easily recycled and the recycling rate can be improved. PP (polypropylene) or the like is used as the synthetic resin, and a blow molding method is preferable as a molding method.

Further, it is preferable that the outer frame 2 is subjected to an edging treatment on the surface thereof to suppress light reflection, so that the outer frame 2 is in a so-called matte state.

The inner box 3 housed in the outer frame 2 as described above is
It is made of cardboard that is water resistant. That is, one piece of material cut out in a predetermined development view shape is assembled by bending it along a predetermined folding curve, and an example of the development view is shown in FIG.

According to this embodiment, the side surface portion 9 is extended from each side edge of the quadrilateral bottom plate portion 8. The side surface portion 9 is formed in a trapezoidal shape having a slightly longer outer edge so that the inner box 3 has an inverted trapezoidal shape when assembled. In addition, two triangular sealing pieces 10 are formed between the side edges of the side surface portions 9. Therefore, due to the sealing piece 10, there is no cut even at the corner, so that water leakage does not occur.

Further, on the outer edge of the side surface portion 9, a folded edge piece 21 for forming a locking edge portion 11 described later is formed.
The folded edge piece 21 is for forming the rectangular locking edge portion 11 that locks to the locking step portion 6 of the outer frame 2 and according to the illustrated embodiment, It is composed of five folded edge pieces 21 so that the upper surface of the edge portion 11 is doubled.
A folding curve 22 is formed between each folded edge piece 21 so as to be appropriately mountain-folded and valley-folded. Further, notches 23 are provided at both ends of the folded edge piece 21 located second from the outer side, so that a locking edge portion 11 on the side edge side, which will be described later, can be recessed.

The inner box 3 having the above-mentioned structure is formed of thick paper. As the thick paper, for example, water-resistant compressed recycled paper or laminated recycled paper can be used. When such recycled paper is used, the bulkiness is reduced, storage is easy, and the possibility of recycled resources is increased by using recycled paper.

Next, a method of assembling the middle box 3 having the above-described structure will be described. Side portions 9 are substantially raised on four sides of the bottom plate portion 8 and sealing pieces 10 are overlapped with each other to form a short side portion. It is superposed on the outside of the side surface portion 9.

Further, the folded edge piece 21 extending to the side surface portion 9 on the long side is sequentially folded inward along the folding curve 22 to form the square locking edge portion 11. On the other hand, the folding edge piece 21 on the short side is also folded in the same manner, and the end portion is the locking edge 1 on the long side.
It is made to incline in the notch 23 formed in 1.

Then, at the overlapping portion, for example, a screw 24
Is fastened to fix each locking edge portion 11. Instead of the screw 24, an adhesive agent or staple may be used. At this time, the locking edge portion 11 presses the upper edge portion of the sealing piece 10 folded back to the corner portion. In the embodiment shown in FIGS. 10 to 12, the upper surface portion of the locking edge portion 11 is double formed, but as shown in FIG. 13, the outermost folded edge piece 21 is formed on the side surface portion 9. You may make it attached.

When the inner box 3 is assembled as described above,
The locking edge 11 reinforces the opening of the inner box 3.
Further, the locking edge portion 11 can be used as a handle when lifting or moving.

The lid 4 mounted on the inner box 3 as described above is
Like the inner box 3, it is made of thick paper. That is, the standing piece 1 having a narrow width is formed on each of the four sides of the rectangular top plate 12 through the folding curve 22.
3 is extended and the standing piece 13 is bent to form the inner box 3
So that it fits inside the. According to the illustrated embodiment, the standing piece 13 has a tongue piece 25 formed by the standing piece 13 in the lateral direction protruding beyond the extension line of the side edge in the longitudinal direction. As will be described later, the tongue piece 25 rises from the edge when the lid 4 is attached to the opening of the inner box 3,
It will be a knob when removing the lid 4. The tongue piece 25 is
You may extend in the standing piece 13 of a longitudinal direction. The lid 4 may be made of water-resistant compressed recycled paper or bonded recycled paper as in the case of the inner box 3.

Next, fresh fish is transported according to the method of using the outer frame 2 and the inner box 3 and the lid 4 having the above-described structure, or the flow of goods using the transportation apparatus 1 according to the present invention. The case will be described as an example.

The producer, that is, the fisherman, places the caught fresh fish in the wholesale wholesale market. This landed fresh fish is handed to the fishermen in the market. The fishery industry purchases the inner box 3 (including the lid 4) and borrows the outer frame 2 from the market. If the outer frame 2 is owned by the market, it is convenient at the distribution stage.

A fisherman who purchases the middle box 3 and borrows the outer frame 2 stores the fresh fish, which is a commodity, in the middle box 3 and fills it with a cooling agent such as ice, if necessary. At this time, since the inner box 3 in the present invention is subjected to water resistance treatment and the sealing pieces 10 form the corners, water does not leak. Further, since the locking edge portion 11 is formed on the inner box 3, the locking edge portion 11 can be used as a handle and is easy to handle.

After storing the fresh fish and the like, the lid 4
To the opening. When installing this, the top plate 12
Since the upright pieces 13 provided on the periphery of the box closely contact the side surfaces 9, the opening of the middle box 3 can be sealed. Moreover,
Since each side surface portion 9 is formed in a tapered shape so as to be narrowed downward, the more the lid 4 is pushed, the tighter the fitting can be. Therefore, there is no possibility that the lid body 4 will come off unexpectedly,
It is extremely hygienic because dust and the like do not enter. In addition, the storage of the fresh fish in the inner box 3 may be performed by inserting the inner box 3 into the outer frame 2, or may be inserted into the outer frame 2 after being stored.

On the other hand, to remove the lid body 4, since the tongue piece 25 extending from the upright piece 13 is present at the corner, the tongue piece 25 may be picked up and pulled up. The tongue piece 25 has a base end connected to the upright piece 13, but a tip end is a free end without coming into close contact with the upright piece 13 and the locking edge portion 11, and thus it is easy to hang a finger.

Next, the fisherman stacks the inner box 3 inserted in the outer frame 2 on a transport vehicle or the like. At this time, the locking edge portion 11 of the inner box 3 engages with the locking step 6 of the outer frame 2, and the periphery of the inner box 3 is protected by the outer frame 2. Further, in the state where the locking edge portion 11 is engaged with the locking step portion 6, the bottom portion of the middle box 3 is located above the lid body 4 of the lower middle box 3 but keeps an interval where it does not contact. Has been formed. Therefore, the inner boxes 3 do not contact each other. Further, the upper half portion of the locking edge portion 11 of the middle box 3 projects above the outer frame 2, but this projecting portion is located in the locking edge portion 11 of the outer frame 2 which is overlaid on the upper side. Therefore, there is no risk of being crushed or damaged. In other words, in the stacked state, the inner box 3 is almost completely surrounded and protected by the outer box 2.

The fishermen transport the fresh fish, which is a product, to the wholesale market of the consuming region in the state of being piled up as described above. Even during this transportation, the inner box 3 protected by the outer frame 2 does not collapse. Further, since the outer frame 2 has excellent heat insulating properties and heat retaining properties, it is possible to prevent deterioration of freshness.

In the wholesale market of consuming regions,
We sell to small retailers such as general fish shops and large retailers such as chain stores. The small box 3 is taken out from the outer frame 2 and handed to the retailer. That is, the retailer takes the merchandise together with the inner box 3, brings it back to the store, arranges the inner box 3 at the storefront, or transfers it to a showcase for sale to general consumers. When pulling out the inner box 3 from the outer frame 2, as described above, by inserting a finger into the cue portion 20b provided on the vertical bar 5b and grasping the engaging edge portion 11 of the inner box 3 and pulling it out. Good.

On the other hand, for large retailers, the outer frame 2
Deliver each. And, while keeping it in the inner box 3 in the outer frame 2,
Bring to a store such as a supermarket, arrange the necessary amount at the store, and store the others in a frozen warehouse. Therefore, since the outer frame 2 is used, transportation and storage can be easily performed even if the transaction volume is large.

Regarding the use of the outer frame 2, since the market holds the ownership of the outer frame 2, the large retailer pays the rental fee of the outer frame 2 to the market and borrows it. In addition, the used outer frame 2 is returned at the time of purchase. In this way, if the outer frame 2 is owned by the market, fishermen and retailers do not need to prepare their own outer frame 2, thus contributing to cost savings. Moreover, the stock amount of the outer frame 2 can be adjusted in each market by, for example, data communication according to the catch amount. By doing so, the stock of the outer frame 2 can be minimized. Further, since the outer frame 2 can be used repeatedly, the generation of waste is extremely small. Furthermore, the outer frame 2 that is damaged or has reached the end of its useful life can be recycled as a synthetic resin material. Therefore, the outer frame 2 as described above is also useful in terms of environmental protection.

On the other hand, the inner box 3 and the lid 4 are disposable, but since they are made of paper, there is no problem in processing unlike the conventional foam polystyrene container. In addition, recycled paper can be used, which is suitable for resource reuse.

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, but can be appropriately implemented without changing the configuration described in the claims. For example, in the embodiment, the case of transporting fresh fish has been described, but the transport device according to the present invention can be applied to transport of not only fresh fish but also vegetables, fruits, flowering trees, or meat. .

[0038]
