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 storing various products in the packaging container, if the space between the packaging container and the product is large, the product may rattle in the packaging container during transportation, etc., and the product may be damaged or deformed. In order to prevent the product from being damaged or deformed, a cushioning material is generally arranged in the gap between the packaging container and the product to fix the product. A conventional example of such a cushioning material is shown in FIG. A cushioning material 100 shown in this conventional example has a main body sheet 101 made of corrugated cardboard or the like, and legs 102 formed of foamed polystyrene are bonded to both ends of the main body sheet 101, and the legs 102 provide a gap between the product and the packaging container. In addition to filling the gaps generated in the product, it prevents the rattling of the product, and cushions the impact with the elasticity inherent in polystyrene foam.

  By the way, since products having various weights are stored in the packaging container, it is necessary to adjust the cushioning property of the cushioning material according to the weight of the product. By increasing / decreasing the receiving area of the main body sheet 101, that is, when the product is heavy, the pressure-resistant strength of the cushioning material is increased, and the receiving area is increased in order to reduce the deformation amount against load impact, and the product is light In order to increase the cushioning property of the cushioning material, the cushioning property was manipulated by reducing the receiving area. However, in such a method, the cushioning property of the cushioning material is determined by the receiving area of the leg 102, and it is necessary to prepare each cushioning material having a receiving area corresponding to the product of each weight. Is cumbersome and expensive.

Therefore, as shown in FIG. 10, Patent Document 1 includes a convex portion forming sheet 201 that is formed in a rectangular shape and a rectangular convex portion locking sheet 202 that is slightly smaller than the convex portion forming sheet 201. The convex portion forming sheet 201 is bent so as to be wound inward from both ends, and both ends of the bent convex portion forming sheet 201 are applied to the raised convex portion locking sheet 202 from the outside. The cushioning material 200 is formed in such a manner that a convex portion 203 having a triangular cross section is formed on each side of the convex portion forming sheet 201, and the cushioning property is increased by inserting or removing the reinforcing member 204 in the convex portion 203. A cushioning material 200 configured to be adjustable has been proposed.

It is designed to be maintained in a bent state.

  When the product 4 is stored in the packaging container 5, as shown in FIG. 5, the product 4 loaded on the cushioning material 1 is sandwiched between the side plates 22 and 23, and both end surfaces are support plates. Further, the product 4 is held in a suspended state by the holding body 2 held by the support bodies 3 and 33 and supported by the support body 3 and is stored in the packaging container 5 in this state. In this way, the product 4 accommodated in the packaging container 5 is prevented from rattling in the front-rear direction and the left-right direction by the side plates 22, 23 and the support plates 32, 33. Is added, the load on the product 4 is absorbed by the stacking plate 21 being bent.

  Next, with reference to FIGS. 6-8, the method to reduce the deformation amount with respect to the load impact of the loading board 21 in which the product 4 is loaded is demonstrated in the shock absorbing material 1 which concerns on this invention. FIG. 6 is an exploded perspective view of the cushioning material according to the present invention, and is a perspective view showing a state in which a cut-and-raised portion is formed on the support. FIG. 7 is a side view showing a state where the cushioning material stacking plate according to the present invention is bent. FIG. 7A shows a state in which a cut-and-raised portion is not formed on the support, and FIG. The case where the raising part is formed is illustrated. FIG. 8 is an enlarged perspective view showing a cut-and-raised portion formed on the support of the cushioning material according to the present invention, wherein (a) is a cut-and-raised portion formed so as to be in the longitudinal direction; ) Shows a cut-and-raised part formed so as to be in the horizontal direction.

  In order to reduce the deformation amount of the loading plate 21 with respect to the load impact, as shown in FIG. 6, before assembling the holding body 2 and the support body 3, this portion is placed along the bottom plate 31 along 3 b provided on the support body 3. Is bent vertically to form a cut and raised portion 38. As described above, when assembling the holding body 2 and the support body 3, the stacking plate 21 is provided with a protrusion 38 a formed integrally with the cut and raised portion 38 so that the cut and raised portion 38 does not fall down. The cut-and-raised part 38 is locked in a state bent vertically.

  Thereby, when the cut-and-raised part 38 is not formed, the stacked product 21 is supported only by the support plates 32 and 33 in the vicinity of both ends in the long side direction. If the product 4 is heavy and an impact is applied vertically downward to the product 4, the loading plate 21 may be greatly bent as shown in FIG. 7A, but the cut-and-raised portion 38 is formed. Thus, the stacking plate 21 is supported by the support plates 32 and 33 and the cut-and-raised portion 38, and as shown in FIG. 7B, the deformation amount of the stacking plate 21 with respect to the load impact can be reduced.

By doing so, a plurality of thin tubes 8 are formed by the corrugated plate 7 between the flat plates 6. The corrugated cardboard sheet thus configured has a defined direction of receiving a load impact. The direction in which the load impact is received is defined by whether the direction is parallel or perpendicular to the longitudinal direction of the plurality of thin tubes 8 formed by the corrugated plates 7 between the flat plates 6 of the corrugated cardboard sheet. More specifically, there are a direction in which a load is received parallel to the longitudinal direction of the narrow tube 9 (hereinafter referred to as a longitudinal direction X) and a direction in which a load is received perpendicular to the longitudinal direction of the narrow tube 9 (hereinafter referred to as a lateral direction Y). is there.

  Therefore, when the amount of deformation of the loading plate 21 with respect to the load impact is reduced by forming the cut-and-raised portion 38 on the support 3 as described above, the cut-and-raised portion is formed as shown in FIG. By forming the portion 38 so as to be in the longitudinal direction X, the pressure-resistant strength of the stacking plate 21 can be further increased, and as shown in FIG. By forming in the direction Y, the cushioning property of the stacking plate 21 can be increased. If the support plates 32 and 33 are also in the horizontal direction Y, the cushioning property of the stacking plate 21 can be further enhanced.

  The shape, number and position of the cut and raised portions 38 formed on the support 3 can be changed as appropriate. Further, by combining the cut-and-raised part 38 formed so as to be in the longitudinal direction X and the cut-and-raised part 38 formed so as to be in the horizontal direction Y as described above, products having various weights are obtained. It is possible to adjust the buffering property according to the above. Further, the position and size of the protrusion 38a formed integrally with the cut-and-raised portion 38 are appropriately determined as long as the formed cut-and-raised portion 38 can be locked in a vertically bent state. It is possible to change.

  In addition, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the holding body 2 and the support body 3 are formed of corrugated cardboard sheets. However, as long as this is a material having elasticity such as a corrugated cardboard sheet, other materials may be used. Moreover, in the said embodiment, although the buffer material 1 was comprised by assembling two types of molded products of the holding body 2 and the support body 3, this can also be assembled from a single plate, and three or more types of moldings are possible. It is also possible to assemble from a product.
