  The above-described integrated packaging material can easily accommodate the components in the packaging material, and a large number of the accommodated components can be carried to the assembly site as they are, so that high working efficiency can be obtained. However, since the shape as a packaging material becomes large, there is a disadvantage that the material cost becomes high. Moreover, a large space is required for storing the packaging material when not in use.

  The divided type packaging material is advantageous in that the divided individual packaging materials are smaller in size than the integrated type packaging material, the material cost can be reduced, and the storage space when not in use can be reduced. However, it is not easy to accommodate a plurality of parts in a predetermined position so as to cover two individually separated packaging materials. Furthermore, it is not easy to handle a package in which a plurality of parts are packaged with the first and second packaging materials, and it is difficult to pack the package and unpack it at the destination. Furthermore, there is an inconvenience that a plurality of parts cannot be transported together when transporting the parts after unpacking.

  The present invention has been made in view of the circumstances as described above, and can also facilitate the housing operation, packaging operation, and unpacking operation of the components while taking advantage of the advantages of the split-type packaging material as it is. It is an object of the present invention to provide a more improved parts packaging material.

  The component packaging material according to the present invention includes a first main body member having a component receiving recess for holding one end side of a component to be stored, and a second main body having a component receiving recess for holding the other end side of the component. A member, and a rod-shaped connecting member that connects the first body member and the second body member, and a component is provided in the component housing recess of the first body member and the component housing recess of the second body member. When the first and second main body parts are accommodated in the first main body part and the second main body part, the first and second main body parts are formed with engaging and disengaging grooves, respectively.

  In the above-described component packaging material, only the first main body member and the second main body member that receive both end portions thereof receive the components to be accommodated, and the material can be saved. Further, the first main body member and the second main body member are small in size as compared with a packaging material having the whole as one member, and the storage space when not in use can be reduced. The accommodation recess only needs to be able to hold the end of the component to be accommodated, and of course may have a shape along the end of the component. The depth, size, and shape of the housing recess are appropriately determined depending on the parts to be housed. Moreover, you may provide an accommodation recess not only in one but in several places according to the number of the components accommodated.

  When accommodating a component, one end of the component is accommodated in the first body member, and the other end of the component is accommodated in the second body member.

Therefore, the operation | work which accommodates components is also easy, and the operation | work which packs the packaging body after accommodation and also unpacks becomes easy. Furthermore, after unpacking, a large number of parts can be transported at the same time in the package, so that various operations at the parts transport destination are facilitated. The length of the rod-shaped connecting member may be such that the first main body member and the second main body member are not separated from each other at least when a large number of parts are transported at a time in the package.

  In the component packaging material according to the present invention, space portions are formed on both sides of the bottom portion of the engagement / disengagement groove in the groove width direction and parallel to the engagement / disengagement groove, and the rod-shaped connecting material enters the space portion. have. In this embodiment, it is possible to prevent the rod-like connecting material from being carelessly detached from the engaging and disengaging groove, and high stability can be obtained in the handling of the package containing the parts.

  Any space may be used as long as it forms a space, such as a groove cut out on both sides of the bottom of the engagement / disengagement groove, or a protrusion provided so that a space is formed on both sides of the bottom of the engagement / disconnection groove. . Moreover, as a latching | locking part of a connection material, if it prevents from detaching | releasing from an engagement / disengagement groove | channel, such as what formed the protruding item | line continuously or intermittently, a shape etc. will be defined arbitrarily.

  In another aspect of the component packaging material according to the present invention, the engagement / disengagement groove has a depth reaching the bottom surface of the engagement / disengagement groove and a cut groove in a direction perpendicular to the engagement / disengagement groove on both sides of the engagement / disengagement groove. It is formed alternately. Thereby, the rod-shaped connecting member can be easily inserted (inserted) into the engagement / disengagement groove. Moreover, in the component packaging material of this form, there exists an advantage which can shape | mold easily each main body member by in-mold foam molding.
