  In the conventional packing member shown in FIGS. 13 to 18, when there is a gap between the inner surface of the packing box 105 and the side end surface of the partition 102, the partition 101 is subjected to a horizontal impact. Therefore, there is a problem that the storage space 106 constituted by the partitions 101 and 102 is displaced. Conventionally, there has been a problem that the product 107 stored in the storage space 106 may be damaged due to the displacement of the storage space 106 when this impact is applied.

  Further, in the conventional packaging member shown in FIGS. 13 to 18, since the weight of the product 107 and the impact in the vertical direction are applied to the protrusion 103 a, it is necessary to give the protrusion 103 a high strength. For this reason, conventionally, there has been a problem that it is necessary to form the protruding portion 103a by laminating and bonding a plurality of cardboard members, or by using a foamed polystyrene having high strength. In addition, in this way, when the protrusion 103a is formed by laminating and bonding a plurality of cardboard members, the number of parts increases, and an assembly operation for bonding the plurality of cardboard members There was a problem that the number of assembly steps increased. Further, when the protruding portion 103a is formed of foamed polystyrene, the foamed polystyrene is more expensive than corrugated cardboard, and there is a problem that the material cost of the protruding portion 103a increases.

Moreover, in the paper partition (packing member) disclosed in the above-mentioned Patent Document 1, when the paper partition (packing member) is arranged in a cardboard packaging box, if there is a gap between the inner circumferential surface of the packaging box, the horizontal direction There is an inconvenience that the positions of the first partition plate and the second partition plate are shifted due to the impact. As a result, a displacement of the storage space constituted by the first partition plate and the second partition occurs, so that the product stored in the storage space is damaged due to the displacement of the storage space due to the impact in the horizontal direction. There is a problem that there are cases.

  Moreover, in the assembly-type packaging cardboard partition container (packing member) disclosed in Patent Document 2, when it is arranged in the cardboard box, there is a gap with the inner surface of the cardboard box. When receiving the impact in the direction, there is a disadvantage that the storage space is displaced. For this reason, there is a problem that the product stored in the storage space may be damaged due to the displacement of the storage space due to the impact in the horizontal direction.

  Moreover, since the partition (packing member) disclosed in Patent Document 3 has a structure that supports the entire lower surface of the product, there is no space on the lower surface side of the product. For this reason, there is a problem that the product is easily damaged when subjected to an impact in the vertical direction.

  In the packaging member made of corrugated cardboard according to the second embodiment, as shown in FIG. 10, a partition 51 in which a side surface portion 51a, a bottom plate portion 51b, and a cylindrical protruding portion 51c are integrally formed is provided. . In addition, as shown in FIG. 11, each partition 51 is provided with seven slits 51d. The partition 51 is integrally provided with eight reinforcing pieces 51e at the end on the side where the slit 51d is formed. In addition, the partition 51 is provided with eight folds 51f for forming the reinforcing piece 51e. In addition, the partition 51 is provided with four guide portions 51g that serve as guides for insertion into the packing box 5 (see FIG. 9). The guide portion 51g suppresses the position of the bottom plate portion 51b from shifting outward and also has a function as a cushioning material. The partition 51 is provided with four cuts 51h for forming the guide portion 51g. Each guide 51g of each partition 51 is provided with five folds 51i. In addition, a fold line 51j is provided in the bottom plate portion 51b of the partition 51. The partition 51 is an example of the “first partition” in the present invention. The slit 51d is an example of the “first slit” in the present invention. The protrusion 51c is an example of the “first protrusion” in the present invention. In addition, as shown in FIG. 9, the partition 2 which has the structure similar to 1st Embodiment is engage | inserted by the slit 51d of the partition 51. As shown in FIG.

  In the second embodiment, as described above, by providing the bottom plate portion 51b integrally with the partition 51, the number of parts can be reduced as compared with the case where the bottom plate portion 51b is provided separately from the partition 51. Further, by providing the cylindrical protruding portion 51 c integrally with the partition 51, the number of parts can be reduced as compared with the case where the protruding portion 51 c is provided separately from the partition 51.

  Next, with reference to FIG. 10 and FIG. 11, the assembly method of the partition 51 of the packaging member made from corrugated board by 2nd Embodiment is demonstrated. First, the fold line 51i (see FIG. 11) is bent horizontally. As a result, the guide portion 51g protrudes outward from the partition 51, and the guide portion 51g and the bottom plate portion 51b are formed to extend in the direction perpendicular to the side surface portion 51a. Next, the fold line 51j is formed into a cylindrical shape by bending the bottom plate portion 51b in the same direction so as to be sequentially rounded. Thereby, the cylindrical protrusion part 51c is formed. Further, the reinforcing piece 51e is formed by bending the fold 51f horizontally by 90 °. Thereby, the partition 51 as shown in FIG. 10 is formed. By fitting the partition 2 into the partition 51 formed in this way, the partition structure (packing member) of the second embodiment shown in FIG. 9 is formed.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiment but by the scope of claims for patent, and all modifications within the meaning and scope equivalent to the scope of claims for patent are included.

  For example, in the above embodiment, a TV tuner is shown as an example of a product stored in the packaging member of the present invention. However, the present invention is not limited to this, and can be applied to other products other than the TV tuner. .

  Moreover, in the said 1st Embodiment, although the example which fits the seven partitions 2 with respect to a pair of partition 1 was shown, this invention is not restricted to this, Other than seven with respect to a pair of partitions 1 Two or more partitions may be fitted.

  Moreover, in the said embodiment, although the example which provides two protrusion parts made from a cylindrical corrugated board so that it may protrude upwards from the upper surface of a top plate was shown in this embodiment, this invention is not limited to this, A top plate In addition, it is not necessary to provide a cylindrical protrusion.

  Moreover, in the said 1st Embodiment, although the example which affixes the projection part made from a cylindrical corrugated cardboard with a double-sided tape on the upper surface of a baseplate and a top plate was shown, this invention is not restricted to this, FIG. As shown in the modification, only the center part of both side parts of the bottom plate part 153 is bent inward, so that both side parts of the top plate 154 are inwardly integrated with the bottom plate part 153 together with the cylindrical cardboard projections 153a. A cylindrical corrugated cardboard protruding portion 154a may be formed integrally with the top plate 154. In this way, the number of parts and the number of assembling steps can be reduced as compared with the case where the protruding portion is formed separately from the bottom plate and the top plate and is attached to the bottom plate or the top plate with double-sided tape.
