Description

  The present invention relates to a cushioning material for protecting a product from an external impact that occurs when the product is transported.

  When various products are stored in the packaging container, if there is a large gap between the packaging container and the product, the product may rattle in the packaging container during transportation, and the product may be damaged or deformed. Therefore, in order to prevent the product from being damaged or deformed, a cushioning material is generally disposed in the gap between the packaging container and the product.

Here, conventionally, as this type of cushioning material, most molded products and cut-out products made of synthetic resin such as foamed polystyrene, etc., but the cushioned material made of foamed polystyrene has a bulky body, so transportation, There was inconvenience in stock. Recently, there is an increasing demand for recycling of cushioning materials, and synthetic resins such as foamed polystyrene having low recyclability are being avoided. Thus, in recent years, paper cushioning materials have begun to attract attention, and in particular, the demand for cardboard cushioning materials has increased. This cardboard cushioning material has the advantage that it conforms to the outer shape of the required parts of various products and can be easily formed into a shape that matches the shape of the gap between the outer shape and the packaging container. As an example of the cushioning material manufactured, a laminated cardboard cushioning material formed by laminating cardboard materials is disclosed (for example, see Patent Document 1).

  However, in the conventional laminated cardboard cushioning material, packaging design can be performed very easily, but the laminated cardboard cushioning material has an eye direction, and depending on the direction, the pressure resistance strength is high, but the cushioning property On the contrary, there are cases where the cushioning property is high but the pressure resistance is poor. Therefore, in the laminated cardboard cushioning material, there is a large difference in the pressure resistance and cushioning properties depending on the direction of the eyes, so when using a cushioning material composed of only one laminated cardboard, the pressure resistance and cushioning properties. It is difficult to combine both of the above, and when a heavy product is placed on the cushioning material, there is a problem that the article to be cushioned is deformed by vibration or impact during transportation.

  The present invention has been made in view of the above problems, and relates to a shock-absorbing material that is easy to assemble and has excellent pressure resistance and cushioning properties for protecting a product from an external impact that occurs when the product is transported.

In order to achieve the above object, a flat plate and a corrugated plate are laminated, and a transverse direction perpendicular to the longitudinal direction of the thin tube formed by the flat plate and the corrugated plate is perpendicular to the flat plate and the thin tube. In a cushioning material comprising a laminated cardboard having a longitudinal direction parallel to the longitudinal direction, the cushioning material comprises a first laminated cardboard, a second laminated cardboard, and a plate-like cardboard containing the first laminated cardboard, The wall surface portion corresponding to each side surface of the first laminated cardboard is formed continuously and the wall surface portion is developed in a flat plate shape, and the first laminated cardboard is provided on the wall surface portion on one end side of the plate-shaped cardboard. The second laminated cardboard is provided on a wall surface portion on the other end side of the plate-like cardboard, and the first laminated cardboard is assembled by bending the plate-like cardboard. Encapsulated, a flat plate of the said first cut surface of the laminated cardboard second laminated cardboard orthogonal to the wale direction, the first laminated cardboard and to close in between at least one of said wall portions A mode in which the second laminated cardboard is disposed, a longitudinal direction of the first laminated cardboard and a lateral direction of the second laminated cardboard are arranged in parallel, and a flat plate of the second laminated cardboard is in contact with a buffered object. It is used in .

Here, in the cushioning material of the present invention, the flat plate of the first laminated cardboard is connected to the wall surface portion on one end side of the plate-like cardboard, and the flat plate of the second laminated cardboard is on the other end side of the plate-like cardboard. It can be connected to the wall surface.

In the cushioning material of the present invention, at least one of the wall surfaces of the plate-like cardboard is provided with a latching portion fixed to a packaging container in which the cushioning material is accommodated at the side end of the wall surface. Can be.

According to the cushioning material of the present invention, at least the laminated cardboard arranged in the transverse direction receiving a load perpendicular to the longitudinal direction of the thin tube and the laminated cardboard arranged in the longitudinal direction receiving the load parallel to the longitudinal direction of the thin tube The laminated cardboards arranged one by one and arranged in the horizontal direction in which the articles to be buffered are placed are arranged on the upper side, and overlap with the laminated cardboards arranged in the horizontal direction in the load direction of the articles to be buffered. Since the laminated cardboards arranged in the longitudinal direction are arranged on the lower side, the cushioning material can have both pressure resistance and cushioning properties. Therefore, even when a heavy cushioned article is placed on the cushioning material, deformation of the cushioned article due to vibration or impact during transportation can be avoided, so that the cushioned article can be highly cushioned. It becomes possible to protect.
In addition, it further includes a plate-like cardboard formed by connecting a plurality of wall surfaces, and the laminated cardboard arranged in the horizontal direction and the laminated cardboard arranged in the vertical direction are attached to the plate-like cardboard. Therefore, the configuration of the cushioning material and its assembly are simplified, the mass productivity of the cushioning material can be improved, and the work efficiency can be increased.
Further, since the laminated cardboard arranged in the longitudinal direction is included in the plate-like cardboard by bending the plate-like cardboard, the cushioning material is used even when a heavy article to be buffered is placed. Can be kept stable, and the above-described high buffering action can be reliably exhibited.

  Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a laminated cardboard used for a cushioning material according to an embodiment of the present invention, and FIG. 2 is a diagram showing a structure of the laminated cardboard shown in FIG.

  As shown in FIG. 1, this laminated cardboard 1 is formed by laminating the cardboard materials shown in FIG. 2, and is composed of a flat plate 2 and a corrugated plate 3 bent into a wave shape of a continuous mountain valley. 2 and a plurality of corrugated plates 3 are alternately laminated, and a plurality of thin tubes 5 are formed by the corrugated plates 3 between the flat plates 2 by bonding the flat plates 2 and the peaks 4 of the corrugated plates 3 with an adhesive. It is composed.

  Further, a direction to receive a load impact is defined in the laminated cardboard 1 shown in FIG. 1, and the direction to receive the load impact is a plurality of thin tubes formed by corrugated plates 3 between the flat plates 2 of the laminated cardboard 1. 5 is defined by whether it is parallel or perpendicular to the longitudinal direction (arrow Z direction in the figure). More specifically, a direction in which the load F1 is received in parallel with the longitudinal direction Z of the narrow tube 5 (that is, a direction in which a load impact is applied to the cut surface A perpendicular to the flat plate 2 and the X direction in the figure). There is a direction that receives the load F2 at right angles to the longitudinal direction Z of the narrow tube 5 (that is, a direction that receives a load impact on the outer surface 2a of the flat plate 2 and is the Y direction in the figure).

  Here, in the X direction (hereinafter referred to as the longitudinal direction X) that receives the load F1 parallel to the longitudinal direction Z of the thin tube 5, the pressure resistance is high and the deformation amount with respect to the load impact is the smallest. There is a disadvantage that it is scarce. On the other hand, in the Y direction (hereinafter referred to as the lateral direction Y) that receives the load F2 perpendicular to the longitudinal direction of the thin tube 5, the cushioning property is high, but on the other hand, the pressure resistance is poor and the deformation amount against the load impact is the largest. There are drawbacks.

  Therefore, in the case of using a cushioning material composed of only one laminated cardboard 1, it can receive a load impact only in one of the longitudinal direction X and the lateral direction Y described above, When receiving a load impact in the longitudinal direction X (that is, when a buffered article is placed on the cut surface A), the pressure resistance is too high and the cushioning property is poor. There is a risk that the article to be buffered may be deformed due to vibration or impact. Further, when receiving a load impact in the lateral direction Y (that is, when a shock-absorbing article is placed on the outer surface 2a of the flat plate 2), the cushioning property is too high and the pressure resistance is poor, and the amount of deformation with respect to the load impact is the largest. Since it is large, there is no particular problem when placing a relatively lightweight article to be buffered. However, when a heavy article is placed, the laminated corrugated cardboard 1 is greatly deformed and is the same as when using the longitudinal direction X. In addition, the article to be buffered may be deformed by vibration or impact during transportation.

  Therefore, the present embodiment is characterized in that the cushioning material is constituted by a plurality of laminated cardboards, and the arrangement of these laminated cardboards with respect to the load direction of the article to be buffered is devised. Below, the structure of the shock absorbing material which concerns on this embodiment is demonstrated in detail using drawing.

  FIG. 3 is a development view of the cushioning material according to the embodiment of the present invention. The cushioning material K according to this embodiment is composed of two laminated cardboards 1, an upper outer wall surface portion 6 serving as an outer upper surface, a left outer wall surface portion 7 serving as an outer left surface, and a lower surface when the cushioning material K is assembled. A plate-like corrugated cardboard 50 having a lower wall surface portion 8, a right wall surface portion 9 serving as a right surface, an upper inner wall surface portion 10 serving as an inner upper surface, and a left inner wall surface portion 11 serving as an inner left surface is provided. The wall surface parts 6 to 11 are connected continuously via fold lines 12 to 17 shown in FIG. Of these folds 12 to 17, the fold 12 at the center of the upper outer wall surface portion 6 is formed in a half-cut shape.

  Of the upper outer wall surface portion 6, the upper side (shaded portion in the figure) partitioned by the half-cut crease 12 is laminated cardboard 1 (hereinafter referred to as "horizontal laminated cardboard") arranged in the horizontal direction Y during assembly. 1a "), and a laminated cardboard 1 (hereinafter referred to as" longitudinal ") that is enclosed in a plate-like corrugated cardboard 50 and assembled in the longitudinal direction at the time of assembly in the shaded portion of the left inner wall surface part 11. The laminated corrugated cardboard 1b ") is affixed. In the present embodiment, as shown in FIG. 3, both the horizontal laminated cardboard balls 1a and the vertical laminated cardboard 1b are configured such that the outer surface 2a (see FIG. 1) is attached. The width Wb of the vertical laminated cardboard 1b is configured to be larger than the width Wa of the horizontal laminated cardboard 1a.

  A rear side wall surface portion 19 which is a rear surface when the cushioning material K is assembled is connected to the left end portion of the upper outer wall surface portion 6 via a fold line 18. The folding parts 22 and 23 protrude and are connected. On the other hand, a front side wall surface portion 25 which is a front surface when the cushioning material K is assembled is connected to the right end portion of the upper outer wall surface portion 6 via a fold line 24, and the front side wall surface portion 25 has fold lines 26 and 27. Folding parts 28 and 29 are projected and connected. Further, latching portions 30 and 31 for fixing the cushioning material K in the packaging container are provided protruding from the left end portion and the right end portion of the lower side wall surface portion 8. With the above configuration, the plate-like cardboard 50 is formed by connecting the plurality of wall surface parts 6 to 11, 19 and 25 via the fold lines 12 to 18 and 24 shown in FIG. 3. . In addition, in the fold lines 12 to 18, 20, 21, 24, 26, and 27 shown in FIG. 3, the alternate long and short dash line is a mountain fold, and the two-dot oblique line is a valley fold.

  When assembling the cushioning material K, first, the laminated cardboard 1b of the vertical shape is enclosed by the plurality of wall surface parts 6 to 11 of the plate-like cardboard 50 while the folds 12 to 17 of the plate-like cardboard 50 are bent. Next, the rear side wall surface portion 19 and the front side wall surface portion 25 are erected inward by bending the creases 18 and 24. Finally, the folds 20, 21, 26, and 27 are bent, and the folded portions 22, 23, 28, and 29 are formed on the laminated laminated corrugated cardboard 1b, the lower wall surface portion 8, and the right wall surface portion 9. The assembly of the cushioning material K is completed by inserting it into the gap. FIG. 4 shows a completed assembly of the buffer material K. In this embodiment, the horizontal laminated cardboard 1a and the vertical laminated cardboard 1b are attached to the plate-like cardboard 50 formed by connecting the plurality of wall surfaces 6 to 11, 19, and 25 in this way. Since the configuration of the buffer material K and the assembly thereof are simplified, the mass productivity is excellent and the working efficiency can be increased.

  In the present embodiment, a plate-shaped cardboard 50 is provided on the cushioning material K, and the horizontal cardboard corrugated cardboard 1a and the vertical cardboard cardboard 1b are attached to the plate-shaped cardboard 50. The structure in which the laminated cardboard 1b is included is that if the outer surface 2a of the horizontal laminated cardboard 1a and the cut surface A (see FIG. 1) of the vertical laminated cardboard 1b are directly attached, the article to be buffered is placed. In this case, the buffer material K becomes unstable due to its structure, and the high buffering action described later cannot be exhibited. Further, the above assembling method is an example and is not limited to this order.

  Next, the buffering action of the buffer material K will be described with reference to the drawings. FIG. 5 is a perspective view showing a packaging device using the cushioning material according to the embodiment of the present invention, and FIG. 6 shows a state where the article to be cushioned is placed on the cushioning material according to the embodiment of the present invention. FIG. In the cushioning material K of the present embodiment, the horizontal laminated cardboard 1a is arranged on the upper side of the cushioning material K, and the lower side of the cushioning material K is overlapped with the horizontal laminated cardboard 1a in the load direction of the article to be cushioned. Is characterized in that vertical laminated cardboards 1b are arranged.

  As shown in FIG. 5, the packaging device includes an outer packaging box (or packaging container) 35 for housing the article to be buffered (or product to be packaged) 40 and the article to be buffered 40 placed on the packaging. The base part 36 accommodated in the bottom part of the container 35, the buffer materials 37 and 38 for preventing the damage | damage or damage of the buffered article 40 by the vibration or impact at the time of transport, etc., and the buffer according to this embodiment The material K is comprised.

  When packing the article to be buffered 40, the buffer material K is supported by the support part 39 provided on the base part 36, and the buffer material 37 provided on the base part 36 is used to lower the buffered article 40. While fitting so that a corner part may be held, the said buffered article 40 is mounted in the buffer material K. FIG. Next, the article to be buffered 40 is stored in the outer packaging box 35, and finally, a cushioning material 38 is inserted between the outer packaging box 35 and the article to be cushioned 40, and the cushioning material 38 is placed above the article to be cushioned 40. The outer packaging box 35 is closed.

  Here, as shown in FIG. 6, the cushioned article 40 is placed on two cushioning materials K, and in each cushioning material K, horizontal laminated cardboard on which the cushioned article 40 is placed directly. 1 a is arranged on the upper side of the cushioning material K, and the vertical laminated cardboard 1 b enclosed in the plate-like cardboard 50 is arranged on the lower side of the cushioning material K. That is, in the cushioning material K shown in FIG. 6, the article to be buffered 40 is placed on the outer surface 2a of the horizontal laminated cardboard 1a in the state shown in FIG. A vertical laminated corrugated cardboard 1 b enclosed in a corrugated cardboard 50 is disposed. At this time, as shown in the drawing, the horizontal direction Y of the horizontal laminated cardboard 1a and the vertical direction X of the vertical laminated cardboard 1b are oriented so as to be the same as the direction of the load F of the article 40 to be buffered. At the same time, since the vertical laminated cardboard 1b is disposed on the lower side of the cushioning material K so as to overlap the lateral laminated cardboard 1a in the direction of the load F of the buffered article 40, the cushioning material K has cushioning properties. The load F of the shock-absorbing article 40 is directly absorbed by the high-layer laminated cardboard 1a, and the shock-absorbing article 40 is stabilized by the vertical laminated cardboard 1b having a high pressure resistance and the least amount of deformation with respect to the load impact. I will support it.

  In this way, the cushioning material K compensates for the pressure strength, which is a disadvantage of the horizontal laminated cardboard 1a, by the vertical laminated cardboard 1b arranged on the lower side, and the horizontal laminated cardboard 1a arranged on the upper side has The cushioning property, which is a drawback of the laminated corrugated cardboard 1b, is made up.

  As described above, the cushioning material K according to the present embodiment includes one horizontal laminated cardboard 1a and one vertical laminated cardboard 1b, and the horizontal laminated cardboard 1a on which the article to be buffered 40 is placed. Is disposed on the upper side, and the laminated cardboard 1b of the vertical side is arranged on the lower side so as to overlap the laminated cardboard 1a of the horizontal line in the load direction of the article 40 to be buffered. It becomes possible to have both the property and the cushioning property. Therefore, even when a heavy shock-absorbing article 40 is placed on the shock-absorbing material K, deformation of the shock-absorbing article 40 due to vibration or impact during transportation can be avoided. It is possible to protect with a high buffering effect.

  In addition, the said embodiment is only an explanatory example, The scope of the present invention is not limited to the said embodiment, Based on the meaning of this invention, the shape, dimension, material, etc. of each structural article are changed. It is possible that they are not excluded from the scope of the present invention.

  For example, in the above-described embodiment, the cushioning material K is configured to have one laminated cardboard 1a and one laminated cardboard 1b each having a total of two laminated cardboards. Depending on the above, a configuration in which three or more laminated cardboards are provided in the cushioning material K may be adopted. At this time, it is possible to provide a configuration in which one or both of the horizontal laminated cardboard 1a and the vertical laminated cardboard 1b are provided.
