  However, when using a side opening / closing type box, if a conventional cushioning material is used, the lighting fixture and the cushioning material may be separated during insertion into the box, and workability is not good. There's a problem.

  In addition, when the box in which the lighting apparatus is packaged in this way is transported in a flat state, the shade may jump up in the box, cause rattling, and the shade may be damaged.

  Therefore, an object of the present invention is to allow an article such as a disk-shaped lighting fixture to be easily inserted into a box and to protect the packaged article from an impact.

  In order to solve the above-described problems, the present invention is configured such that corner contact plates are connected to corner portions of the bottom plate via mountain fold lines inclined with respect to the insertion direction into the box, and the corner contact plates are attached to each other with belt-shaped holding pieces. And place a crease line in the middle of the holding piece, provide a gap between the holding piece and the bottom plate, place the article along the bottom plate, and bring the corner abutment plate into contact with the opening edge of the box. When inserted, the corner abutment plate rises from the bottom plate, the holding piece bends inward, the side portion of the article fits into the gap between the holding piece and the bottom plate, and the article is held down by the holding piece.

  In the packaging cushioning material, the bottom plate is cut and raised to form an instrument fixing piece that engages with the article so that the article is secured to the cushioning material.

  Further, a buffer piece sandwiched between the cuts is provided at the boundary between the bottom plate and the corner plate, and the buffer piece is pushed inward so that the outer peripheral portion of the article is received by the buffer piece.

  When the lighting fixture is packaged using the cushioning material according to the present invention, when the lighting fixture is inserted into the box obliquely from above with the box tilted, the lighting fixture is held by the corner abutment plate and the holding piece, and the fixture is fixed. Since it is fixed in one piece, it is possible to prevent the luminaire from falling off the cushioning material and to easily carry out the packaging work even if it is not supported manually.

  In addition, when transporting in a state where the box is placed flat, the packaged luminaire abuts against the corner plate, is received by a buffer piece, and is restrained by a holding piece from above, preventing the shade from jumping up. The box is reinforced with a holding piece from the inside to prevent the shade from being damaged.

  Furthermore, when the luminaire is taken out of the box with the box tilted, the luminaire is held by the holding piece and the fixture fixing piece, so that the luminaire is prevented from falling off from the cushioning material, and the removal work is performed. It can be done easily.
