[Industrial applications]

 The present invention relates to a box body and a box. In particular, the present invention relates to a box main body and a box made of a plastic lightweight structure plate, which is useful when collecting waste by separating it into combustible waste and non-combustible waste.

[0002]

[Prior art]

 Recently, environmental issues have been discussed from a global perspective. In particular, for the disposal of waste, there is no need to dispose of it, or from the perspective of effective use of resources, it is necessary to sort waste into combustible waste and non-combustible waste for collection. By the way, a conventional box or case uses an injection container made of plastic, and although this injection container is durable, the box or case is heavy and difficult to handle. The mold had to be used, and the cost of the mold was high, and since the mold was used, there was the disadvantage that only fixed sizes could be manufactured.

[0003]

[Problems to be solved by the device]

 Although there is a call for the need to separate waste into combustible and incombustible waste for collection, there is no trash box with multiple box bodies connected for separation, and the work to increase and decrease the box body It is easy and cheap, but the development of something is awaited.

【Example】

 The present invention will be described in detail below based on specific embodiments shown in the accompanying drawings. The plastic lightweight structure plate 1 is made of polyolefin such as polypropylene or polyethylene, polyester, nylon or the like and those reinforced with fibers or filler, and polypropylene is preferably used among them. Examples of polypropylene include homopolymers of propylene and random or block copolymers of propylene and ethylene, and propylene and α-olefins (butene-1, pentene-1, etc.). A block copolymer is particularly preferable from the viewpoint of cold resistance. Examples of the plastic lightweight structural plate 1 include a hollow sheet as shown in FIG. 1 and a foamed sheet. A hollow sheet plastic lightweight structure plate 1 can be formed by extrusion molding in which a plurality of ribs 3 are arranged in parallel in a cavity 2. When the plastic lightweight structure plate 1 is made of polypropylene or polyethylene, it can be recycled.

A box body is formed of such a plastic lightweight structure plate 1, and a development view thereof is as shown in FIG. That is, the rectangular bottom plate 11 is formed. Next, the side plates 14 and 15 of the same size are connected to each other on both sides of the bottom plate 11 that face each other, with bending lines 12 and 13 interposed respectively.

A small connecting plate 18 is provided at one end and a large connecting plate 19 is provided at the other end with bending lines 16 and 17 interposed at both ends of one side plate 14. Bending lines 20 and 21 are provided at both ends of the other side plate 15, and a large connecting plate 22 is provided at one end and a small connecting plate 23 is provided at the other end. The size of the small connecting plates 18 and 23 and the large connecting plates 19 and 22 should be the same size as the other both side plates of the bottom plate 11 when folded to form a box by folding at the folding lines 16, 17, 20 and 21. So that the side plates 14 and 15 and the connecting plates 18, 19, 22 and 23 are each bent inward at a right angle to form a box, and the joining line between one small connecting plate 18 and one large connecting plate 19 is formed. Then, the sizes of the small connecting plates 18 and 23 and the large connecting plates 19 and 22 are set so that the joining line between the other large connecting plate 22 and the small connecting plate 23 is displaced. This is because if the two joining lines match, the boxes cannot be made rigid and become weak when they are connected.

When the side plates 14 and 15 are bent upright along the bending lines 12 and 13 and are erected, the U-shaped slits 24 and 25 are formed at the upper edge of the side plates 14 and 15 for fitting the lid insertion pieces to be described later. . Further, since the box bodies are connected by screws, the small connecting plate 18 has screw insertion holes 26, the large connecting plate 19 has screw insertion holes 27, the large connecting plate 22 has screw insertion holes 28, and the small connecting plate 23. A screw insertion hole 29 is formed in each of these.

Further, a lid is formed of the plastic lightweight structure plate 1, and a development view thereof is as shown in FIG. 3, and this example is a lid used for connecting three box bodies. That is, three charging holes 32 are formed in the top plate 31 at the center of the generally rectangular plastic lightweight structure plate so as to face the opening of the box body. Holding plates 35 and 36 are connected to both sides of the top plate 31 with bending lines 33 and 34 interposed respectively, and the holding pieces 35 and 36 are fitted at positions facing the U-shaped slits 24 and 25 of the box body. Extend joint pieces 37 and 38. The shape of the charging hole 32 may be an appropriate shape such as a round hole or a square hole. The material of the lid 61 may be the same as or different from that of the box body 52.

Next, the assembly of the box body and the box of the present invention will be described. First, in order to assemble the box body, as shown in FIG. 4, the side plates 14 and 15 are vertically folded and erected with respect to the bottom plate 11 along bending lines 12 and 13. Next, the small connecting plates 18 and 23 of the side plates 14 and 15 and the large connecting plates 19 and 22 are bent at a right angle to the inside to form a box body, and the large connecting plates 19 and 22 are provided outside the large connecting plates 19 and 23. Using an end plate 41 of a size that combines the small connecting plate 23 with the small connecting plate 23, a screw 43 made of a recyclable plastic such as polypropylene or polyethylene is inserted from the inserting hole 42 of the end plate 41 into the inserting hole 27 of the large connecting plate 19. The small connecting plate 23 is passed through the insertion hole 29 to fix the large connecting plate 19 and the small connecting plate 23 to form the box body 51.

Subsequently, the box bodies 52 formed in the same manner are placed next to each other, and the screws 43 are inserted through the insertion holes 26 and 28 of the small connection plate 18 and the large connection plate 22 of the box body 51. Insert the holes 27 and the insertion holes 29 of the small connecting plate 23 and fix them. Further, the box main bodies 53 formed in the same manner are placed next to each other, and the screws 43 are inserted from the insertion holes 26 and 28 of the small connection plate 18 and the large connection plate 22 of the box main body 52 into the insertion hole 27 of the large connection plate 19 and the small connection plate. Insert into the insertion hole 29 of the connecting plate 23 and fix.

Since the other box bodies are not connected to the small connecting plate 18 and the large connecting plate 22 of the box main body 53, the end plate 41 is arranged, and the screw 43 is inserted through the insertion hole 42 of the small connecting plate 18. 26 and the insertion hole 28 of the large connecting plate 22 and fix it. The lid 61 bends the sandwiching pieces 35 and 36 downward at the bending lines 33 and 34 at a right angle.

Subsequently, the fitting pieces 37, 38 of the lid 61 are inserted into the U-shaped slits 25, 24 of the box bodies 51, 52, 53 to form boxes. When attaching the plastic bag 71 having the handle 72 to the box main body 51, 52, 53, as shown in FIG. 5, pass the handle 72 of the plastic bag 71 through the fitting pieces 37, 38 and then the U-shaped slit. Fits on 25/24. An example of a plastic bag 71 having a handle 72 is shown and described.However, when the plastic bag does not have a handle, the opening edge of the plastic bag is covered on the upper edge of the opening of the box body 51, 52, 53. Insert the insertion pieces 37 and 38 of the lid 61 into the U-shaped slits 24 and 25, and attach the plastic bag to the box bodies 51, 52 and 53.

In this way, it is extremely easy to attach the plastic bag 71 to the box bodies 51, 52, 53. Further, the state of displacement of the joining line 81 between the small connecting plate 23 and the large connecting plate 19 and the joining line 82 between the large connecting plate 22 and the small connecting plate 18 is a plan view of the box bodies 51, 52, 53. This is clearly shown in Figure 6. Joining line 81 and joining line 82 The joining line 81 and joining line 82 are intentionally shifted when joining because the shape is not stable and a weak box plate is formed unless separate plate members are connected to each other.

Further, the slits 25, 24 into which the fitting pieces 37, 38 of the lid 61 are fitted are not limited to U-shaped slits, but may be linear slits. Although the trash can is described in the above embodiment, the trash can can be used as a box other than the trash can. Also, the screw 43 can be fixed with one touch, so if the so-called one-touch type screw is used, the work is particularly easy.
