  The simple division portion 3 is integrated with the first member 1 and the second member 2 over the entire length in the longitudinal direction of the first member 1 and the second member 2 at the boundary between the first member 1 and the second member 2. It is in a connected state. The simple division part 3 is constituted by a groove-like part 3a or a connecting part 3b. The connecting portion 3b as the simple dividing portion 3 is formed in the form of one or a plurality of rods, plates, etc. along the longitudinal direction of the first member 1 and the second member 2 and having a small thickness and width as shown. It may be what was done. Moreover, the groove-shaped part 3a as the simple division | segmentation part 3 may be formed in one or more at least on the upper surface side or the lower surface side. That is, the simple division unit 3 plays a role of enabling easy and accurate work of manually dividing the first member 1 and the second member 2. Of course, in the case of cutting by an appropriate means using a heat ray, in addition to the above role, it also plays a role of a guide.

  Further, notches 13 and 13 are formed on the upper surface side of the corner portion of the first member 1 opposite to the simplified division portion 3 side, and the notches 13 and 13 are fitted to the corner portions on the lower surface side. Protrusions 14 and 14 having a shape to be inserted are formed. Further, a concave portion 15 is formed on the upper surface side of the first member 1 on the side of the simple division portion 3, and a ridge 16 having a shape that fits into the concave portion 15 is formed on the lower surface side. Further, notches 23 and 23, protrusions 24 and 24, recesses 25, and protrusions 26 are formed in the second member 2 in the same manner.

  In this example, the packing material A is an in-mold foam-molded product made of a composite resin of polystyrene and polyethylene, and is about 30 to 50 times (0.033 g / L to 0.025 g / L). . As an example of the part B, an automobile clutch / torque converter can be exemplified.

  Next, with reference to FIG. 2, a description will be given of a package that accommodates four parts B arranged in two horizontal rows and two vertical rows using the packaging material A described above. First, two packing materials A (A1, A2) are prepared, and one packing material A1 is divided into left and right parts by the simple division part 3 and separated into a first member A11 and a second member A12. . Then, as shown in FIG. 2A, the first member A11 is juxtaposed on the right side, the other packing material A2 is on the center, and the second member A12 is on the left side, with a predetermined interval. Thereby, a component holding region is formed between the first component holding recess 11 of the first member A11 and the second component holding recess 21 of the packaging material A2. Similarly, a component holding region is also formed between the second component holding recess 21 of the second member A12 and the first component holding recess 11 of the packaging material A2.

  Although not essential, in this case, in order to eliminate waste of materials, each of the first member A11, the other packing material A2, and the second member A12, as shown in FIG. , 21 and the component housing recesses 12 and 22 are divided into two in the horizontal direction at an appropriate position p, and are designated as upper parts AU1, AU, AU2 and lower parts AD1, AD, AD2. In the illustrated example, the upper part AU is separated into two parts in the packing material A2 due to the division position p, and the lower part AD is an integrated object connected by the simple division part 3.

  After the separation, as shown in FIG. 2C, the three upper parts AU1, AU (AU), and AU2 are arranged from the right side to the left side in this order, with the dividing plane as the lower side. Then, a part of the lower right side of the disk-shaped portion 31 of the component B is held in the first component holding recess 11 of the upper portion AU1 on the right side, and inside the second component holding recess 21 of the upper portion AU on the center right side. A part of the lower left side of the disk-shaped part 31 of the part B is held. Furthermore, a part of the lower right side of the disk-shaped portion 31 of the component B is held in the first component holding recess 11 of the upper left portion AU in the center, and the second component holding recess 21 in the left upper portion AU2 is held. Then, a part on the lower left side of the disk-shaped portion 31 of the part B is held. The same is done for the two component holding recesses formed in the longitudinal direction of the upper portions AU1, AU (AU), AU2. Thereby, four parts B will be in the state by which a part of the lower side was held by the 1st part holding crevice 11 and the 2nd part holding crevice 21 of packing material A.

  Next, the first member A11, the other packing material A2, and the second member separately prepared on the upper portions AU1, AU (AU), and AU2 in the packing body in the posture shown in FIG. The member A12 is stacked. Thereby, the region not covered by the component holding recesses 11 and 21 formed in the upper portions AU1, AU (AU) and AU2 in the side region of the disk-shaped portion 31 of the component B is the first member A11 and the other portion. It is covered with the packaging material A2 and the component housing recesses 12 and 22 formed in the second member A12. Then, the notches 13 and the recesses 15 formed on the upper surfaces of the upper parts AU1, AU (AU), and AU2 are stacked on the first member A11, the other packing material A2, and the lower surface of the second member A12. By fitting the protrusions 14 and the ridges 16 formed in, the stacked postures of the members stacked vertically are stabilized. In addition, on the upper surfaces of the first member A11, the packing material A2, and the second member A12 that are stacked, a component holding region is formed by each of the holding recesses 11 and 12, so that the next-stage component B can be held. Yes.

  In this manner, after the parts B are stacked in an appropriate number of steps, the lower parts AD1 and AD previously cut on the uppermost first member A11, the other packing material A2, and the second member A12. The packing operation is completed by stacking AD2 such that the divided surface is the upper side.

  FIG. 3 shows a side view of the packaging body C in which the parts B are packed in three rows horizontally and seven rows vertically as described above. The reference numerals for the respective parts are the same as those used in FIGS. As can be seen from this figure, in the packaging body C, only a part of each part B is covered with the packing material A so that the parts B are packed without contacting each other, and the entire part is wrapped with the packing material. Compared with, the material cost required for the packing material A can be reduced.

  Moreover, since the packaging material A can be obtained from the simple division part 3, the left and right packaging materials A11 and A12 can be obtained, so that the packaging body C can be created simply by molding one type of packaging material A. From this point, the material cost required for the packing material A can be reduced.

  In addition, it is a style in which only a part of both sides of the part B is packed with a packing material, and even if the part is provided with an upper convex part 32 or a lower convex part 33 at the center as shown in the drawing, Even if the upper convex portion 32 and the lower convex portion 33 are different in size and shape, and even if such a component does not have a convex portion, it can be packed using the same packing material A. There is also.

  Further, the number of the packing materials A constituting the packing body C and the numbers of the component holding recesses 11 and 21 and the component receiving recesses 12 and 22 of the packing material A can be arbitrarily determined.

  In addition, the package C shown in FIG. 3 is usually used for actual conveyance and storage after a film is wound around the whole to stabilize the posture or the whole is accommodated in a predetermined case. Although not shown, although some material costs are wasted, the packing materials A11, A, and A12 can be used as they are as the lowermost and uppermost packing materials. In this case, the work of dividing the packing material into upper and lower parts can be omitted, and the packing work is simplified.

  In the illustrated example, since the component B has a disk-shaped portion 31, all of the component holding recesses 11 and 21 and the component receiving recesses 12 and 22 have a shape of a part of an arc in a plan view. However, the shape of each of the component holding recesses 11 and 21 and the component receiving recesses 12 and 22 is determined by the contour of the component to be stored, and the first component holding recess 11 and the second component holding recess 21 may have a different shape, and similarly, the first component housing recess 12 and the second component housing recess 22 may have different shapes.
