  If the device supported by the foamed resin block is like a large-sized television receiver, the foamed resin block may be deformed by the weight of the device, and in short, may collapse. If this happens, the packaging will loosen and the overall merchandise value, including the packaging, will decrease.

  The present invention has been made in view of the above points, and an object of the present invention is to increase the strength of a foamed resin block that supports a bottom corner portion of a device in a cardboard case, and to realize it at a low cost.

  In order to achieve the above object, the present invention provides a packaging apparatus for a device in which a foamed resin block supporting a bottom corner portion of the device is inserted into a cardboard case surrounding the device. A slit extending in the surface direction is formed, and a reinforcing cardboard piece is inserted into the slit.

  According to this configuration, it is possible to support the weight of the device with a low cost cardboard piece and prevent the foamed resin block from being deformed. Since the cardboard piece itself is inserted into the slit of the foamed resin block, there is no fear of falling down.

  The present invention is characterized in that, in the device packaging apparatus having the above-described configuration, the slit is a dead end in front of the top surface of the foamed resin block.

  According to this configuration, it is only the foamed resin that comes into contact with the device, and the device is not damaged by the hard cardboard piece.

  According to the present invention, in the packaging apparatus for equipment having the above-described configuration, the corrugated board piece is bent so that at least a part of a planar shape forms a U-shape.

  According to this configuration, the cardboard piece can support a larger load.

  The present invention is characterized in that the corrugated cardboard piece is cut and raised from the bottom flap of the corrugated cardboard case in the device packaging apparatus having the above-described configuration.

  According to this configuration, the position of the corrugated cardboard piece with respect to the corrugated cardboard case is fixed. Therefore, it is possible to accurately position the foamed resin block within the corrugated cardboard case and prevent positional deviation. Further, it is not necessary to separately prepare a corrugated board material for the corrugated board piece, and the cost can be reduced.

  According to the present invention, it is possible to increase the strength of the foamed resin block with a simple configuration and prevent deformation even if a heavy object is supported.

  The first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a partial vertical sectional view of the packaging device, FIG. 2 is a horizontal sectional view of the packaging device, and FIG. 3 is a plan view of the foamed resin block and cardboard pieces.

  The packaging target of the first embodiment is a television receiver T that indicates the presence of a virtual line. The packaging device 1 is composed of a rectangular parallelepiped cardboard case 2 and a pair of foamed resin blocks 3 that are inserted therein and support the bottom corners of the television receiver T. The cardboard case 2 is of a normal carton type, and flaps are provided on each of the four sides of the upper surface opening and the lower surface opening of the trunk, and the flaps are folded inward to form a box shape. The foamed resin block 3 is made of a commonly used material such as foamed polystyrene. There is also a foamed resin block applied to the top corner of the television receiver T, but this is not shown.

  The foamed resin block 3 has a pedestal 3a that supports the bottom corner of the television receiver T from below, and a vertical wall 3b that surrounds the side of the bottom corner from three sides. As shown in FIG. 3, a planar U-shaped slit 4 is formed in the pedestal portion 3a. The slit 4 extends from the bottom surface of the pedestal portion 3a in the top surface direction, and penetrates from the bottom surface to the top surface in the first embodiment. A reinforcing corrugated cardboard piece 5 bent into a planar U-shape is inserted into the slit 4. The corrugated board piece 5 has the same height as the pedestal portion 3a, and the corrugated ridge is made of material so that the corrugated ridges follow the vertical line.

  When the television receiver T is placed on the foamed resin block 3, the weight of the television receiver T is supported by both the foamed resin and the cardboard. By appropriately setting the size and thickness of the planar shape of the cardboard piece 5, a considerable portion of the weight of the television receiver T can be borne by the cardboard piece 5 and deformation of the foamed resin block 3 can be prevented. Since the corrugated cardboard piece 5 is inserted into the slit 4 of the foamed resin block 3, there is no fear of falling down. Further, since the corrugated board piece 5 is bent in a U shape in plan, it can support a large load.

  A second embodiment of the present invention is shown in FIGS. 4 is a partial vertical sectional view of the packaging device, and FIG. 5 is a horizontal sectional view of the packaging device. In the following embodiments, the same components as those in the first embodiment are denoted by the same reference numerals as those used in the description of the first embodiment, and the description thereof is omitted.

  The difference between the second embodiment and the first embodiment is the depth (height) of the slit 4. That is, in the first embodiment, the slit 4 penetrates from the bottom surface of the pedestal 3a to the top surface, but the slit 4 in the second embodiment is a dead end in front of the top surface. The height of the cardboard piece 5 is also commensurate with it.

  According to this configuration, it is the resin portion of the foamed resin block 3 that comes into contact with the television receiver T, and the television receiver T is not damaged by the hard corrugated cardboard piece 5.

  A third embodiment of the present invention is shown in FIGS. FIG. 6 is a partial vertical sectional view of the packaging device, and FIG. 7 is a horizontal sectional view of the cardboard case.

  In the third embodiment, the cardboard piece 5 is formed by cutting and raising from the bottom flap 2 a of the cardboard case 2.

  According to this configuration, since the position of the corrugated cardboard piece 5 with respect to the corrugated cardboard case 2 is fixed, the foamed resin block 3 can be accurately positioned in the corrugated cardboard case 2 to prevent positional deviation. Further, it is not necessary to separately prepare a corrugated board material for the corrugated board piece 5, and the cost can be reduced.

  Each embodiment of the present invention has been described above, but various modifications can be made without departing from the spirit of the present invention.

  The present invention can be used for a packaging device of a type in which a bottom corner portion of a device is supported by a foamed resin block in a cardboard case.
