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 the space between the packaging container and the product is large, the product may rattle in the packaging container during transportation, and the product may be damaged or deformed. Therefore, in order to prevent damage and deformation of the product, it is common to place a cushioning material in the gap between the packaging container and the product and fix the product. In some cases, cardboard or polystyrene foam or the like molded into an arbitrary shape is fixed to a single plate formed of cardboard or the like.

  As such a cushioning material, as shown in FIG. 6, a bonding position 10 is illustrated in advance by a sewing blade or the like on a fixing plate 2 formed of corrugated cardboard or the like, and a cushioning function such as laminated corrugated cardboard or polystyrene foam is used. A method is generally employed in which the object 3 is positioned in accordance with the perforations and adhered by an adhesive or the like. However, in positioning by such a perforation or the like, since the buffer is easily displaced, it takes time for the bonding work, and the work efficiency is not good. Further, in the bonding method in which only one bottom surface of the buffer is bonded to the fixed plate as shown in FIG. 6, there is a problem that the bonding strength is weak and the buffer is easily peeled off from the fixed plate.

Here, as a method for facilitating the positioning as described above, there has been proposed a method in which a cut-and-raised portion is formed in advance at a position where the buffer is bonded, and positioning is performed in accordance with the cut-and-raised (for example, a patent) Reference 1).
JP-A-9-278067

  However, in the method proposed in Patent Document 1, positioning work is easy, and the adhesive work of the buffer is improved, but the adhesive strength is not improved at all, and after packing the product, The problem that the buffer is peeled off from the cushioning material during transportation or the like has not been solved.

  In view of the above-mentioned problems, the present invention facilitates positioning of the buffer, improves the bonding work efficiency, and further enhances the bond strength of the buffer, in the buffer material manufactured by bonding the buffer to the fixed plate. It is an object of the present invention to provide a cushioning material that prevents the buffer from being peeled off during transportation.

  In order to achieve the above object, the present invention provides a fixed plate formed from a single plate and a buffer material formed by adhering a buffer having a buffering action to the fixed plate. A cut and raised portion is formed at a position, and two adjacent surfaces of the buffer are bonded to the upper surface of the fixing plate and the side surface of the cut and raised portion.

  Further, the present invention is characterized in that the cut and raised are formed in the same shape as the bonding surface of the buffer.

  In the present invention, the fixing plate is composed of a flat plate and a corrugated plate, and a longitudinal direction receiving a load in parallel with a longitudinal direction of a thin tube formed by the flat plate and the corrugated plate, and a longitudinal direction of the thin tube. It is formed from the corrugated board sheet | seat which has the horizontal direction which receives a load at right angle.

  Further, the present invention is characterized in that the cut and raised are formed such that the longitudinal direction of the thin tube in the cut and raised is perpendicular to the upper surface of the fixed plate.

  According to the present invention, the buffer is formed of a laminated corrugated cardboard formed by laminating a plurality of corrugated cardboard sheets, and the longitudinal direction of the thin tubes of the laminated corrugated cardboard is perpendicular to the upper surface of the fixed plate. It is characterized by being glued to.

It is characterized by being glued to.

  According to the first configuration of the present invention, the positioning of the buffer can be facilitated only by matching the cut and raised formed on the fixed plate, so that the positioning operation is facilitated and the bonding work efficiency can be improved. In addition, the adhesion of the buffer is a three-dimensional adhesion of the bottom surface and the side surface orthogonal to the bottom surface, so that the adhesive strength can be enhanced.

  In addition, according to the second configuration of the present invention, in the cushioning material of the first configuration, the cut-and-raised portion is formed in the same shape as the bonding surface of the cushioning material, so that the positioning operation of the cushioning material becomes easier. . Moreover, since all the side surfaces of the buffer can be bonded, the bonding strength can be further enhanced.

  Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of a cushioning material 1 according to the present invention, FIG. 2 is a perspective view of a fixing plate 2 used in the cushioning material 1 according to the present invention shown in FIG. 1, and FIG. FIG.

  As shown in FIG. 1, the buffer material 1 is composed of a fixed plate 2 and a buffer 3. As shown in FIG. 2, two rectangular cut-and-raised parts 4 are formed on the fixed plate 2 at positions facing each other. Here, it is a position where these cut-and-raised parts 4 are formed, but the cut-and-raised part 4 is adjacent to the bonding position 2a of the buffered object 3 in order to position the buffered body 3 in accordance with the cut-and-raised part 4 as will be described later. Further, in order to facilitate positioning of the buffer 3, the end surface 4 b of the cut and raised 4 needs to be aligned with the end of the bonding position 2 a of the buffer 3. is there.

  Next, positioning of the buffer 3 will be described with reference to FIG. When positioning the buffer 3, as shown in FIG. 3A, first, the side surface 3 a of the buffer 3 is cut up and brought into contact with the side surface 4 a of 4. By doing so, the buffer 3 can be positioned in the left-right direction. Then, as shown in FIG. 3 (b), the cushioning material 3 is cut and raised and slid along the edge 4, and the end surface 3b of the buffering material 3 is cut and raised to align with the end surface 4b of the buffer 4, thereby performing vertical positioning. be able to.

  Then, the buffer 3 that has been positioned as described above is bonded to the fixed plate 2. At this time, the bottom surface 3 c of the buffer 3 is bonded to the top surface of the fixing plate 2, and the side surface 3 a of the buffer 3 is cut up and bonded to the side surface 4 a of 4. Thus, the cushioning material 1 is completed. In addition, as the said fixed plate 2, the single plate formed from the corrugated cardboard etc. can be used suitably, and the laminated cardboard or a polystyrene foam etc. can be used suitably as the buffering thing 3. FIG.

  Hereinafter, an example of the cushioning material according to the present invention will be described using a case where a corrugated cardboard sheet 5 is used as the fixing plate 2 and a laminated corrugated cardboard 6 is used as the cushioning material 3. FIG. 4 is a perspective view showing the laminated cardboard 6, and FIG. 5 is a perspective view showing a cushioning material using the cardboard sheet 5 and the laminated cardboard 6.

  As shown in FIG. 4, the laminated corrugated board 6 is formed by laminating a plurality of corrugated cardboard sheets. The laminated corrugated board 6 includes a flat plate 7 and a corrugated plate 8 bent in a wave shape of continuous mountains and valleys. A plurality of thin plates 9 are formed between the flat plates 7 by the corrugated plates 8 by alternately laminating a plurality of plates 8 and joining the flat plates 7 and the peaks and valleys of the corrugated plates 8 with an adhesive. is there.

  In addition, the direction in which the load impact is received is defined in the laminated cardboard 6, and the direction in which the load impact is received is the longitudinal direction of the plurality of thin tubes 9 formed by the corrugated plates 8 between the flat plates 7 of the laminated cardboard 6. Defined as parallel or perpendicular to More specifically, the direction of receiving a load impact on the cut surface 6b perpendicular to the flat plate 7 and receiving the load parallel to the longitudinal direction of the narrow tube 9 (hereinafter referred to as the longitudinal direction X), and the flat plate 7 is a direction to receive a load impact on the outer surface 6a of the thin tube 9, and a direction to receive a load at right angles to the longitudinal direction of the narrow tube 9 (hereinafter referred to as a lateral direction Y).

  When the laminated cardboard 6 formed as described above is used as a shock absorber, the laminated corrugated board 6 is arranged in the longitudinal direction X in order to increase the pressure resistance of the shock absorber and reduce the amount of deformation with respect to a load impact. In addition, when it is desired to increase the cushioning property, the laminated cardboard 6 may be arranged in the horizontal direction Y.

  Here, when the laminated cardboard 6 is arranged in the longitudinal direction X, the bottom surface of the laminated cardboard 6 bonded to the corrugated cardboard sheet 5 becomes a cut surface 6 a perpendicular to the flat plate 7. Means that only the end surfaces of the flat plate 7 and the corrugated plate 8 of the laminated corrugated board 6 are bonded, and the bonding area is very small. Therefore, as in the case of the conventional cushioning material shown in FIG. 6, when the adhesive is bonded to the corrugated cardboard sheet 5 only at the cut surface 6a serving as the bottom surface of the laminated corrugated cardboard 6, the adhesive strength is very weak. It will easily peel off.

  However, in the cushioning material 1 according to the present invention, the cut surface 6a serving as the bottom surface of the laminated corrugated cardboard 6 is adhered to the upper surface of the corrugated cardboard sheet 5, and the cut and raised parts 4 are formed on the corrugated cardboard sheet 5, and the side surfaces 4a of the cut and raised parts 4 are formed. Further, since the flat outer surface 6b which is the side surface of the laminated corrugated cardboard 6 is also bonded, a sufficient bonding area can be obtained and the bonding strength is enhanced. Moreover, since it is not a planar adhesion like the conventional cushioning material shown in FIG. 6, but a three-dimensional adhesion by two surfaces, that is, a bottom surface and a side surface perpendicular to the bottom surface, However, it is also strong against the force applied from the side.

  Further, when the corrugated cardboard sheet 5 is used as the fixing plate 2, the cut and raised 4 formed on the corrugated cardboard sheet 5 has the longitudinal direction X and the lateral direction Y as with the laminated cardboard 6. That is, when it is desired to increase the pressure-resistant strength of the buffer and reduce the amount of deformation with respect to the load impact, the cut and raised parts 4 are formed so as to be in the longitudinal direction X together with the laminated corrugated cardboard 6 as shown in FIG. As a result, the pressure strength can be further increased. Further, when the pressure strength is not required, the cut and raised 4 may be formed so as to be in the horizontal direction Y as shown in FIG.

  By forming the cut and raised on the fixed plate as described above and using the cut and raised for positioning the buffer, the buffer can be easily positioned and the working efficiency can be improved. Further, by adhering to the fixed plate by the two surfaces of the bottom surface and the side surface of the buffer, the adhesive strength of the buffer can be enhanced, and the buffer can be prevented from peeling off.

  The above embodiments are merely illustrative examples, and the scope of the present invention is not limited to the above embodiments, and the shape, size, number, material, and the like of each constituent article are arbitrarily set based on the gist of the present invention. Changes are possible and are not excluded from the scope of the invention.
