Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cushioning material made of corrugated cardboard, and more specifically, a cushioning material made of corrugated cardboard, which is arranged between the product and the outer box when the product is stored in an outer box such as a decorative box or a cardboard box, so as to reduce impact. About.

[0002]

[Prior art]

 Conventionally, when storing relatively precise equipment such as a weighing scale as a product in an outer box such as a cosmetic box, a cushioning material is placed between the product and the outer box, and the product is placed inside the box during transportation. In addition, it suppresses the movement and reduces the impact to prevent the product from being damaged. Styrofoam is a typical example of such a cushioning material. Styrofoam cushioning materials are lightweight and have excellent impact mitigation properties, but they are difficult to recycle and have problems with disposal because they are handled as incombustible waste.

[0003] As a cushioning material, in addition to the above-mentioned styrofoam material, a cardboard material is also used. For example, as shown in FIG. 5, large and small types of corrugated cardboard pieces 23a, 23b, 23c, 23d cut out or punched into a predetermined shape on a mount 22 are laminated to obtain a three-dimensional structure. At the time of storage, a product, for example, a side portion of a weighing scale is fitted into the laminated cardboard pieces 23a, 23b, 23c, 23d and stored in an outer box together with a cushioning material.

In the weight scale housed in this manner, movement is suppressed by a buffering portion (intermediate member) composed of laminated cardboard pieces 23a, 23b, 23c, and 23d, and external impact is reduced. The top and bottom surfaces of the platform of the weighing scale are also covered with the backing sheet 22 to reduce the impact. Such a cardboard cushioning material 21 has the advantage that it can be incinerated because it is paper, or it can be relatively easily recycled as recycled paper.

[0005]

[Problems to be solved by the invention]

 However, although the conventional cardboard cushioning material 21 as shown in FIG. 5 has a shock-absorbing property, it is necessary to cut out or punch out the mount 22 and various types of cardboard pieces 23a, 23b, 23c, 23d separately. Yes, more blade dies and equipment were needed. Further, since a large number of cardboard pieces 23a, 23b, 23c and 23d are manually pasted on the backing paper 22 via an adhesive or the like, there is a problem in that it is complicated, time-consuming and costly. In addition, the management of each piece of corrugated cardboard is troublesome, and the manufactured cushioning material has large irregularities even when folded, making it difficult to bind, making it inconvenient to store and deliver, and causing large variations in individual shapes. .

[0006] In view of the above problems, the present invention provides a cushioning material made of corrugated balls that exhibits excellent impact relaxation properties, can be easily manufactured at low cost, and can correspond to various product shapes. The purpose is to provide.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, there is provided a corrugated cardboard cushioning material comprising at least an opposing member for sandwiching a stored item and an intermediate member surrounding the stored item. The present invention provides a cushioning material made of corrugated cardboard, which is formed by bending one corrugated cardboard stencil punched in a developed shape and integrally forming the same.

[0008] Such a cushioning material made of corrugated cardboard has excellent shock-absorbing properties, does not require laborious manual work such as bonding as in the past, and has a corrugated cardboard having a desired shape obtained by a single punching process. It can be easily assembled simply by folding the base paper. After punching, it can be folded in half and bundled and stored easily.

It is preferable that the intermediate member is arranged obliquely in the thickness direction of the stored item and supports the stored item at the inner edge. In this way, by arranging the intermediate member obliquely in the thickness direction of the stored item, a three-dimensional structure is formed, and the stored item is stably supported by the inner edge over the entire thickness direction, effectively absorbing the cushioning characteristic of cardboard. Can be withdrawn.

In this case, it is preferable that the obliquely disposed intermediate member and the opposing member are made of a cardboard cushioning material that is locked at one end. If the intermediate member and the opposing member that are arranged obliquely are locked at one end as described above, the intermediate member can be reliably maintained at an oblique position and a three-dimensional structure can be obtained. It is possible to more stably support in all directions.

[0011] The cardboard cushioning material according to the present invention can be particularly preferably used when the storage object is a flat scale. If the flat-type weighing scale is stored in the outer box using the cardboard cushioning material of the present invention, movement in the box is particularly suppressed by the intermediate member, and the surface and the bottom surface of the weighing platform are opposed to each other. Since the weight scale is covered with the member, the weight scale is entirely protected by the cardboard cushioning material. Even if it receives an impact during transportation or the like, the weight can be sufficiently alleviated to prevent damage to the product.

[0012]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto. Note that the cardboard cushioning material according to the present invention can be applied to, in principle, any object that needs to mitigate the impact received during transportation, etc. The case of storage will be described.

FIG. 1 shows an example of a cushioning material made of cardboard according to the present invention. The corrugated cardboard cushioning material 1 shown in FIG. 1 can be suitably used when storing a flat scale, and has a developed shape as shown in FIG. 2 obtained by stamping corrugated cardboard base paper. One sheet of corrugated cardboard is bent to be integrally formed. For the punching process, a conventional conventional method can be applied. For example, a cardboard base paper can be punched out once by a press using a mold provided with a punching blade. At the same time as punching, not only ruled lines but also cuts and folds can be made.

The punched corrugated cardboard shown in FIG. 2 is composed of opposed members 2a and 2b, a side wall member 5 provided between the opposed members, and intermediate members 3a and 3b. One end 2a of the opposing member (hereinafter, referred to as a first opposing member) is provided with a locking piece 6 at one end thereof, and the other piece 2b (hereinafter, referred to as a second opposing member) is provided with escape holes 8 at four corners. Is provided. Although these relief holes 8 are provided in accordance with the legs protruding from the bottom surface of the weighing scale to be stored, a hole that matches the shape of the storage object may be appropriately formed as necessary. .

The facing members 2 a and 2 b are connected via a side wall member 5. The side wall member 5 has a width corresponding to the thickness (height of the weighing scale) of the stored item so that the opposing members 2a and 2b are substantially parallel when the weighing scale is arranged in the cardboard cushioning material 1. Have.

The one piece 3a of the intermediate member (hereinafter, referred to as a first intermediate member) is provided with a notch 7 into which the locking piece 6 provided on the first opposing member 2a is inserted at the time of assembly. The other piece 3b (hereinafter, referred to as a second intermediate member) is connected to the second opposing member 2b via a connection portion 9. The first and second intermediate members 3a and 3b are directly connected to each other with a ruled line 11 as a boundary.

At the approximate center of each of the intermediate members 3a and 3b, fitting holes 4a and 4b are provided, respectively, and the weight scale is placed in these fitting holes 4a and 4b, and the weight members are placed on the intermediate members 3a and 3b. It is more surrounded. Since the first intermediate member 3a is disposed obliquely in the thickness direction of the product (weight scale) as shown in FIG. 3, its fitting hole 4a is longer than the fitting hole 4b of the second intermediate member 3b. Is formed. By changing the length and shape of the facing member, the side wall member, the intermediate member, and the fitting hole as appropriate, it is possible to cope with various product shapes. In particular, by adjusting the length and arrangement angle of the intermediate members arranged obliquely in the thickness direction, and the length of the fitting holes, it is possible to easily handle products that are taller than the scale. Can be.

Further, the shape of the fitting holes 4a and 4b may be formed according to the outer shape of the storage object, and the intermediate members 3a and 3b may have different shapes. It is not always necessary to fit the storage items into the fitting holes 4a and 4b. However, if the shape of the inner edges of the fitting holes 4a and 4b is as close as possible to the storage items, the movement of the storage items is ensured. The impact can be effectively reduced.

Further, the intermediate member may be formed of a single, double, triple or more corrugated ball according to the thickness of the product, and the facing member may be appropriately changed similarly. For example, when the intermediate member is made of quadruple corrugated cardboard, a large cardboard base paper may be prepared in advance and punched out so that the four pieces constituting the intermediate member are continuous.

A method of assembling the corrugated cardboard cushioning material shown in FIG. 1 from the corrugated cardboard punched into the developed shape shown in FIG. 2 will be described below. First, the opposing members 2a, 2b and the intermediate members 3a, 3b are folded along the ruled line 14 of the connecting portion 9 so as to overlap. Next, the first intermediate member 3a and the second intermediate member 3b are folded along the ruled lines 10, 11, 12 so that they face each other on the inner side. Further, the opposing member 2a and the intermediate member 3a are locked at one end by bending the locking piece 6 along the ruled line 13 and inserting it into the cut portion 7 of the first intermediate member 3a. Buffer material 1 made of metal. It should be noted that the opposing member 2a and the one end of the intermediate member 3a can be locked by staples or the like without providing such a locking piece and a cut portion.

The assembled cushioning material 1 made of corrugated cardboard is arranged such that a product is placed in the fitting holes 4a and 4b of the intermediate members 3a and 3b and stored in an outer box, so that the product is held at the inner edge of the fitting hole. It can be stably supported. FIG. 3 shows a state where the weight scale is arranged in a cardboard cushioning material and stored in an outer box. The weighing scale 15 is housed in an outer box 16 in a state where the main body is surrounded by intermediate members 3a and 3b, and the surface and bottom surface of the mounting table are covered with first and second opposing members 2a and 2b. Although not shown in FIG. 3, the legs protruding in the vicinity of the four corners of the bottom surface of the weight scale 15 are fitted into the relief holes and positioned with respect to the second facing member 2b.

By arranging the weighing scale on the cardboard cushioning material 1 and storing it in the outer box 16 in this way, the weighing scale 15 is stably positioned in the cardboard cushioning material 1, and particularly surrounds the weighing scale. In addition, the side surface of the main body is reliably supported by the first intermediate member 3a which is arranged obliquely in the thickness direction, so that the buffer effect can be very advantageously exerted. In addition, since the cardboard itself has a buffering function, the buffering effect is sufficiently exerted on the surface and the bottom surface of the mounting table covered with the facing member. Therefore, when transporting the weighing scale stored in this way, the cushioning material 1 made of corrugated cardboard exerts an excellent overall shock-absorbing effect and protects the product, regardless of the orientation of the weighing scale. can do.

The cushioning material 1 made of corrugated cardboard shown in FIGS. 1 to 3 can be easily manufactured because one piece of corrugated cardboard, which has been punched into a predetermined developed shape, can be folded and formed integrally. it can. This eliminates the need for a complicated laminating process as in the case of manufacturing a conventional cardboard cushioning material, and enables mass production at low cost. Also, since the flatness is excellent before assembling, for example, if the facing member and the intermediate member are folded in half so that they overlap each other, it is easy to bind and easy to store, transport, and deliver. Thus, for example, storage space can be saved.

Further, since the intermediate member can easily obtain a three-dimensional structure freely in the thickness direction of the product, it is possible to cope with various product shapes and to stably support the product as compared with the conventional cardboard cushioning material. And can exhibit very excellent buffering properties.

Next, FIG. 4 shows another embodiment of the cushioning material made of cardboard according to the present invention. In this cushioning material 1 'made of corrugated cardboard, the first and second intermediate members 3a and 3b provided with the fitting holes 4a and 4b are all horizontally overlapped on the second opposing member 2b, and the fitting holes 4a and 4b are formed. Has a simple structure in which the first opposing member 2a covers the stored items arranged in the first position. The cardboard cushioning material 1 'of FIG. 4 is also formed integrally by bending one piece of cardboard base paper similarly to the cardboard cushioning material 1 shown in FIG. , 2b are connected via a side wall member 5, and the second intermediate member 3b is connected to the first intermediate member 3a and the second opposing member 2b.

When a product is stored in an outer box using the cardboard cushioning material 1 ′, the product is arranged in the fitting holes 4 a, 4 b, surrounded by the intermediate members 3 a, 3 b and sandwiched by the facing members 2 a, 2 b. And store it in the outer box. By storing the product in this way, the product can be stably supported in the cardboard cushioning material 1 ′, and can have an extremely excellent shock absorbing effect.

Also in this embodiment, the larger the area in contact with the inner edge of the fitting hole, the more stable the support. Therefore, the intermediate member has a structure in which three or more cardboards are laminated according to the thickness of the product. You can also.

Note that the present invention is not limited to the above embodiment. The above embodiment is merely an example, and any one having substantially the same configuration as that of the technical idea described in the claims of the present invention and having the same function and effect will be described. However, it is included in the technical scope of the present invention.

For example, in the above-described embodiment, a case where the present invention is applied to a weight scale is described. However, the present invention can be used as a cushioning material for various products, parts, and units such as a personal computer and a clock. The punching shape, folding method, and connection method of each member of the corrugated cardboard can be appropriately changed according to the shape of the product.
