Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a corrugated paperboard box having a cushioning material in which a cushioning material made of corrugated paper is incorporated in a corner portion of a corrugated board box having a double-walled peripheral wall.

[0002]

[Prior art]

 For example, when packing and transporting household air conditioners, electric appliances such as microwave ovens, boxes containing delicate equipment such as microscopes, etc., provide a cushioning material between the object to be packed and the main body case. ing.

As a cushioning material that has been conventionally used, a corner pad made of a synthetic resin foam made of expanded polystyrene, expanded polyethylene, urethane foam or the like is molded into a predetermined shape and the elasticity of the foam is used. Then, it is used alone or as a composite material by bonding this synthetic resin corner pad to a corrugated board material. This cushioning material has good cushioning properties, has an excellent function of protecting the items to be packed from the outside, and is lightweight, so it is easy to handle and is easy to mold.

There is also a case where the main body case itself in which the articles to be packed are stored has a corner pad made of a composite material such as the above-mentioned synthetic resin corner pad or corrugated board material adhered. The main body case is generally a corrugated paper box, and a corner pad made of synthetic resin or composite material is incorporated in the paper box.

[0005]

[Problems to be solved by the device]

 However, if a corner pad made of synthetic resin foam is used as the cushioning material, this pad will not corrode if left unused because it is a petroleum product and will generate a large amount of black smoke when it is discarded when it is disposed of after use. Since it emits a nasty smell or emits an offensive odor, disposal and incineration after using it as a packaging material poses a problem.

In addition, the corner pad, which is made into a composite material by adhering it to a corrugated board material or the like, has a new problem in that it is difficult to separate and collect it when treating it as dust. In particular, under the current situation where there is a demand to prevent waste of resources and protect the global environment, it is the responsibility of the company that shipped the product to reduce, collect or dispose of cushioning materials. The situation is getting closer.

Further, the cushioning material made of this petroleum product has elasticity although it has an excellent cushioning function. Therefore, when the products are stacked, they serve as a reinforcing material for supporting the weight of the products. However, there is also the inconvenience that if a strong body case is used to support the load during stacking, a strong and expensive body case must be used.

The present invention has been made to solve such a problem, and is not only advantageous in terms of cost, but also saves resources, facilitates separate collection, and is excellent in supporting a load for stacking. An object of the present invention is to provide a corrugated paper box having a cushioning material that is easy to manufacture.

[0009]

[Means for Solving the Problems]

 The present invention for achieving the above-mentioned object is a corrugated paper box comprising a corrugated cardboard main body case which is a substantially rectangular box body and a cushioning material in which the main body case is incorporated. A rectangular board, an outer plate of a predetermined width provided on each of the four sides of the board through a valley line, and a top plate of a predetermined width provided on the outer side of each board via a valley line, and A top pad and an inner plate provided via a valley fold line, and the cushioning material is formed by a corner pad incorporated in a corner portion of the main body case. When a cutout is formed at the side end and bending is performed, the entire corner pad is fitted into the space formed between the cutout and the outer plate and the inner plate without using an adhesive. , Corner corners on the four corners of the main unit case. De is cardboard Lumpur papermaking box having a buffer material, characterized in that it has to be located.

[0010]

[Action]

 When the object to be packed is transported in a corrugated cardboard box having the cushioning material configured as described above, or when the corrugated cardboard box is applied to the corners of the objects to be packaged and transported in the main body case, The corner pads of the corrugated cardboard box are tightly housed in the corners, which improves the cushioning of the corrugated cardboard box or body case corners. Further, when assembling this corrugated paperboard box, since no adhesive means is particularly required, neither a pasting process nor an adhesive drying step is required, and excellent workability is exhibited. In particular, since the corner pad can be detached, by removing the corner pad during transportation, the main body case can be transported as a flat flat plate material, and the space during transportation is not large, which is advantageous in terms of cost.

In addition, if a corrugated cardboard angle material is used as the corner pad, the whole can be recycled as waste paper, and even if the corrugated cardboard paper box having a cushioning material is directly buried in the soil or the like and corroded, it is environmentally friendly. It can be easily disposed of without any problems.

Even if a synthetic resin foam body is used for this corner pad, if the corner pad is removed from the main body case after use, the whole main body case will be made of paper, so that it is possible to easily handle separate collection. The paper part can also be discarded as above. Since the corner pads are commercially available, various sizes are easily available and inexpensive, which is advantageous in terms of cost.

FIG. 6 is a schematic perspective view showing another embodiment of the present invention.

As shown in FIG. 1, the corrugated paperboard box 10 having the cushioning material of the present embodiment is used for packing an article W to be packed which is, for example, a home air conditioner, It is attached so as to cover both ends of the article W to be packed, and as shown in FIG. 2, it is tightly housed together with the article W in an outer case 11 made of a corrugated cardboard box. A space 12 is formed between them to protect the article W to be directly or indirectly protected from an impact force from the outside, prevent the article W from moving inside the outer case 11, and load it on a vehicle or the like. In such a case, the stacking load acting from the vertical direction or the like is supported, and the load is protected from directly acting on the article W to be packed.

The corrugated paperboard box 10 having the cushioning material is roughly divided into four corner pads 15 and a main body case 16 as shown in FIG. 3. The main body case 16 is formed by bending. Later, the corner pad 15 is assembled into a box without using an adhesive.

First, the corner pad 15 will be described. The corner pad 15 is composed of an angle portion 13 and an end plate 14 as shown in FIG. 3. An edge of a plate material constituted by laminating a plurality of corrugated paper sheets D each having a shape of core paper 18 and liner paper 18 is chamfered at an angle of 45 degrees, and the edge surface is made of water-soluble vinyl acetate or the like. The L-shaped angle member A as shown in FIG. 4 is formed by bonding with an adhesive. Then, a cut region C having a substantially right angle is formed in the central portion of the L-shaped angle material A, and the end face Ca of the cut region is joined by an adhesive such as vinyl acetate as shown in FIG. Such a corner pad 15 can be formed. That is, the corner pad 15 is composed of three corrugated cardboard laminated sheets S of approximately the same size joined together so that the angles between them are substantially right angles so as to form the corners of a rectangular parallelepiped. There is.

Therefore, since the corrugated cardboard D is provided in a multi-layered manner in the corner pad 15, the buckling function of the core paper 18 has a high cushioning performance, and a corner portion has a so-called rounded portion. Since it is assumed that the squareness is tight without any occurrence, the core paper 18 will be densely present at the corners of the main body case 11 when it is stored in the main body case 11, and the Not only the cushioning property is improved, but also the object W to be packed is housed properly in the main body case 11 without any play.

In particular, when the corner pad 15 is formed, if the corrugated ridgeline r of the core paper 18 is configured to cross the ridgeline r of the corrugated cardboard D located above or below or in the front and back, It can be made strong enough to withstand a load or impact acting from the vertical or horizontal direction.

Next, as shown in FIG. 3, the body case 16 includes upper and lower facing side walls Su and Sd and left and right facing side walls Sl and Sr, respectively, as outer plates 20u, 20d, 20l and 20r. (These are collectively referred to as 20) and the inner plates 21u, 21d, 21l and 21r (these are collectively referred to as 21) have a double structure, and the upper and lower side walls Su and Sd of the outer plate 20 and the inner side. After the corner pad 15 is inserted into the space 22 formed between the plate 21 and the plate 21, it is formed into a box shape as a whole.

An example of the expanded state of the main body case 16 is as shown in FIG. The main body case 16 in this unfolded state is provided with a rectangular substrate 23 in the center, and each of the side walls S (Su, Sd, Sl, Sr) is formed on the four sides of the substrate 23 through valley fold lines T1. Outer plates 20u, 20d, 20l, 20r are provided. The width l1 of the outer plate 20 is slightly larger than the sum of the thickness t1 of the angle portion 13 having an L-shaped cross section of the corner pad 15 shown in FIG. 3 and the inner height h of the angle portion 13. Has been done.

Outside the outer plates 20, top plates 24 u, 24 d, 24 l and 24 r of the side wall portion S are provided via valley fold lines T 1. The width 12 of the top plate 24 is set to be slightly larger than the wall thickness t1 of the angle portion 13.

The top plates 24 are provided with the inner plates 21u, 21d, 21l and 21r via the valley fold line T1. However, among these inner plates 21, notches 26 are formed in the side portions of the upper and lower side walls Su and Sd of the inner plate 21, and the corner pads are provided in the notches 26 when bent. 15 is inserted. The shape of the cutout portion 26 may be any shape as long as the corner pad 15 is completely fitted in the main body case 16.

On the other hand, the inner plates 21l, 21r of the left and right side walls Sl, Sr have a width dimension that fits between the upper and lower side walls Su, Sd, and a mountain fold line T2 is formed in the middle portion. It is adapted to be deformed along the surface of the inserted corner pad 15, and the projecting piece 27 provided at the tip is fitted in the notch hole 28 formed in the substrate 23, and the inner plate 21l , 21r are fixed.

Further, end plates 29 are provided outside the inner plates 21u, 21d of the upper and lower side walls Su, Sd via valley fold lines T1.

Next, the operation of the embodiment will be described. For example, when packaging a home air conditioner, first, the main body case 16 is formed by bending corrugated cardboard paper punched into a shape as shown in FIG. This molding is performed by forming valley troughs T1 between the central substrate 23 and the outer plates 20u and 20d, and between the outer plate 20 and the top plate 24, and the top plate in order to form the upper and lower opposite side walls Su and Sd. A valley fold is performed along each valley fold line T1 between 24 and the inner plate 21. In the case of this valley folding, the end portion of the end plate 29 is located in the vicinity of the valley fold line T1 of the outer plates 20u and 20d, and this end plate 29 is fixed on the substrate 23 with an adhesive to fix the outer plate 20 and the inner plate. A space 22 is formed between the space 22 and the space 21.

In molding the main body case 16, the end plate 29 is not adhered to the substrate 23 but is simply bent and the shape of the main body case 16 is determined using the corner pads 15. good. That is, even if the end plate 29 is not adhered to the substrate 23, if the corner pad 15 is inserted into the space 22 or the like, the outer end 29a of the end plate 29 is fixed in position by the space 22. Since it is pressed by 15, the shape of the main body case 16 can be determined. In addition, the end plate 29 is previously attached to the substrate 23 with an adhesive, and the outer plate 20 and the inner plate 21 are laterally pressed and raised during use to form a space portion. You may make it insert the corner pad 15 in 22. By doing so, the shape of the main body case 16 can be made substantially flat when not in use or during transportation, and it can be transported from the shock absorbing material manufacturing plant to the packing place without being bulky, improving the transportation efficiency and improving the efficiency during transportation. There is also an advantage that it can be easily molded.

The shape of the main body case 16 is determined by inserting the corner pad 15 into the space 22 thus formed. At this time, the corner pad 15 is fitted into the space 22 and the notch 26 without using an adhesive. Further, the outer plates 20l, 20r of the left and right side walls Sl, Sr are also valley-folded along the valley fold line T1, and are attached so as to cover the corner pad 15, and the projecting portion 27 at the tip is fitted into the notch hole 28 of the substrate 23. When combined, the corrugated paperboard box 10 can be formed.

As described above, basically, when an adhesive is not used at the time of assembling, there is no sticking process and the adhesive does not need to be dried, and the corrugated paperboard box 10 can be efficiently assembled in a short time. Will be greatly improved. Moreover, when the corrugated paperboard box 10 is carried after being assembled, the corner case 15 can be removed from the body case 16 so that the body case 16 can be a flat plate member and can be carried without being bulky.

When the corrugated paperboard box 10 is used for packing, two corrugated paperboard boxes 10 are prepared and attached so as to cover both ends of the article W to be packed, such as a home air conditioner, and placed in the outer case 11. Store. The corrugated paperboard box 10 housed in the outer case 11 does not have so-called rounded corners but has a rectangular cushioning material with a tight right angle. It is tightly housed in the case 16 with no gaps, and the core paper 18 is densely present at the corners of the outer case 11, which improves the cushioning property at the time of collision, and the backlash inside the main body case 11 is improved. Therefore, the object W to be packed is prevented from moving. In addition, the buckling function of the core paper 18 and the existence of the space portion 12 exhibit excellent cushioning against external impacts, and protect the article W to be packed inside directly or indirectly. become. Further, the load bearing capacity, which is applied in the vertical direction when loaded on a vehicle or the like, has a high supporting ability, and the load does not directly act on the article W 1 to be packed.

When the corrugated paperboard box 10 is used up after packaging, the corner pad 15 and the main body case 11 can be separated from each other. At this time, when the corrugated cardboard angle material is used for the corner pad 15, the corrugated cardboard box 10 as a whole can be recycled as waste paper, and even if it is buried in the soil as it is and disposed of, it is corrosive and poses a problem for environmental hygiene. It can be easily disposed of. Further, the corner pad 15 is made of synthetic resin foam. The corner pad 15 can be removed from the main body case 16 even when using the one described above, and the paper main body case and the synthetic resin corner pad 15 can be separated to facilitate separate collection of dust. The paper part can be disposed of in the same manner as above.

It should be noted that the above description is one embodiment of the present invention, and the present invention can be variously modified without departing from the gist described in the scope of the utility model registration request.

For example, as shown in FIG. 6, a corrugated paper box 10 having a cushioning material may be attached with an upper lid 32 that covers the cushion box from above. Further, although the above-described embodiment has been described in the vertical relationship. , Such relationships are not necessary. Further, a handle hole 31 as shown in FIG. 5 is formed in the substrate 23, or a cutout portion K (a portion indicated by a broken line) is formed in a part of the outer plate 20 or the inner plate 21 so as to have a ventilation function. It is also possible to use it.

[Effect of device]

 As described above, the corrugated paperboard box having the cushioning material of the present invention is composed of the corner pad and the main body case made of corrugated paperboard configured to cover the outer periphery of the end of the article to be packed. Since the corner pad is inserted in the space of the side wall of the structured main body case, the cushioning property at the time of storage is improved, there is no rattling, and the ability to support the stacking load during loading is high. Even at the time of assembly, since no adhesive means is particularly required, assembly workability is also excellent.

Further, since the corner pads are attached only to the four corners, not only has a sufficient cushioning function, but also the resources of the cushioning material are saved.

If a paper-made corner pad is used and the whole is made of paper, it can be recycled as waste paper, and it can be easily disposed without being a problem in terms of environmental hygiene because it will be corroded even if it is buried in the soil as it is and discarded. Even if a resin-made corner pad is used, no adhesive means is used, so it can be easily removed from the main body case after use and sorted and collected easily.

The corner pad may be a commercially available product, so various sizes are easily available and inexpensive, which is advantageous in terms of cost.
