openings

1a and 1b of the corrugated cardboard sheet 1. The partition wall 1 c partitions between the objects to be packed 3 held in the packing box 4.

The pulp mold member 2 is a pulp mold member formed integrally by pulp mold molding using waste paper or pulp as a raw material. Moreover, the pulp mold member 2 has the

recessed parts

2a and 2b shape | molded corresponding to the external shape of the to-be-packaged goods 3, as shown in FIG.
When the article 3 is accommodated in the recess 2a, a part of the outer shape of the article 3 is held in contact with the inner wall of the recess 2a.

In addition, in the packing using the conventional pulp mold member, it was the structure which prepared two pulp mold members as shown in FIG. 2, and pinched | interposed the packaged goods from both sides.
On the other hand, in this invention, as shown in FIG. 1, by packaging in combination with the corrugated cardboard sheet 1, only one pulp mold member 2 is required. This eliminates the need for one of the pulp mold members compared to the prior art, thereby reducing costs and reducing the space for storing the pulp mold members.

As shown in FIG. 1, the article 3 to be packed is accommodated in the

recesses

2a and 2b of the pulp mold member 2 through the

openings

1a and 1b. Moreover, the electronic device which has the design panel with low tolerance with respect to external force as shown in FIG.
In the present invention, only the main body portion of the article to be packed 3 covered with the strong chassis is accommodated in the concave portion 2a of the pulp mold member 2, and there is no member that abuts and presses against the design panel. For this reason, even an electronic device having low resistance to external force can be stably held.

3A and 3B are diagrams showing the corrugated cardboard sheet according to Embodiment 1, in which FIG. 3A is a developed top view of the corrugated cardboard sheet, and FIG. 3B is a top view after the corrugated cardboard sheet is assembled.
From the sheet unfolded state shown in FIG. 3A, the corrugated cardboard sheet 1 shown in FIG. 3B is formed by folding it in a fold line at a fold line a and bending it in a fold line at a fold line b.

For example, the two sheet surface portions overlap each other by folding the fold line b shown in FIG. 3 (a) into a convex shape and folding the fold lines a on both sides thereof into a concave shape. In this state, by twisting the assembly piece 1c-1 of each sheet surface portion, the state where the two sheet surface portions overlap each other is maintained, and the partition wall portion 1c is formed.

The opening 1a is opened with a size smaller than the outer shape of the article 3 to be packed, and cuts 1A and 1B connected to the opening are formed in the peripheral edge. Further, when the article to be packed 3 is held in the packaging box 4, a part of the article to be packed 3 (part of the design panel) is inserted into the opening 1 b.
As shown in FIG. 1, the packing member according to Embodiment 1 holds two objects to be packed 3. The partition wall 1c partitions between the two objects to be packed 3 accommodated in the

recesses

2a and 2b of the pulp mold member 2 through the

openings

1a and 1b. It can prevent reliably that the to-be-packaged goods 3 contact by this partition wall part 1c.

Further, as shown in FIG. 1, the packing member according to the present invention does not hold the design panel side of the article 3 to be packed, but the load received by the partition wall 1c from the design panel side is to be packed. It plays the role of a stopper that restricts transmission to the object 3.
On the other hand, the corrugated cardboard sheet 1 is crushed when it receives a load perpendicular to the longitudinal direction of the narrow tube rather than when it receives a load parallel to the longitudinal direction (hereinafter referred to as the longitudinal direction) of the thin tube formed of a flat plate and a corrugated plate. Cheap.
Therefore, the partition wall portion 1c is configured in the longitudinal direction in consideration of the eye direction of the cardboard sheet 1. Thereby, it can prevent exactly that the load added to the packaging box 4 from the opposite side to the pulp mold member 2 is transmitted to the to-be-packaged goods 3. FIG.

4A and 4B are diagrams showing the opening of the cardboard sheet, FIG. 4A is a top view of the opening 1a, FIG. 4B is a perspective view of the opening 1a, and FIG. The opening 1a when 3 is inserted is shown. FIG. 5 is a partial cross-sectional view illustrating a state in which an object to be packed is packed with the packing member according to the first embodiment. FIG. 6 is an enlarged view of a cross-sectional portion of FIG.
