Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper box equipped with a cushioning material, and an object of the present invention is to facilitate packaging work.

This will be explained below using a television receiver as an example.

Television receivers can be roughly divided into a picture tube, a chassis containing an electric circuit, an escutcheon, a cabinet, etc., which are assembled together. Usually, the cabinet is manufactured separately and shipped in a packaging box, and the picture tube and electric circuit are included in the cabinet. It will be moved to a factory where chassis, escutcheon, etc. will be assembled.

Once taken out of the packaging box, the cabinet is assembled into a completed television receiver, then placed back into the packaging box and shipped and sold.

In Figures 1, 2, and 3 a and b, 1 is a packaging box made of a cardboard box, etc., and has four flaps 2 and 3 on the top surface.
, 4.5, which can be opened and closed freely.

After the empty television receiver cabinet 6 is housed in this packaging box, cushioning materials 7 and 8 made of foamed polystyrene or the like are press-fitted to protect the corners to protect the interior from vibrations caused by storage and transportation.

Note that a similar cushioning material exists below the cabinet of the television receiver.

A portion of the cushioning materials 7 and 8 is missing, and a portion 9 into which the cabinet 6 of the television receiver is fitted is provided.

The present invention provides a paper box equipped with a cushioning material that facilitates the packing operation in the above-mentioned process, and one embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 4a and 4b, a cushioning material 10 similar to the conventional one is provided with a recess 11 that fits over the upper corner of the cabinet of a television receiver.

A U-shaped split groove 12 of a constant depth is formed on one side plate 13 of the cross-section shaped part formed for the fitting recess 11.

This cushioning material 10 is inserted into the packaging box 1 so as to protect the upper corner of the television receiver 6, as shown in FIGS. 5, 6, and 7.

At this time, the pair of cushioning materials 10.
Since adhesive is applied to 5, the upper flaps 2 and 3
, 4.5, the cushioning material 10.14 is adhered to the side inner surface and the top flaps 2, 4 of the packaging box 1.

In this state, the empty cabinet 6 is stored and transported and arrives at an electrical parts assembly factory.

In an electrical parts assembly factory, the packaging box 1 must first be unpacked, and when the top flaps 2, 3, 4.5 are opened, the cushioning material 14 is attached with adhesive, as shown in Figure 7. Therefore, both ends and the side surface 13 side remain in close contact with the inner surface of the packaging box 1, and only one side surface 17 of the cushioning material 14 rotates together with the top flap 4.

In other words, the cushioning material 10.14 is divided into two at the dividing groove 12 portion.

Therefore, the cabinet 6 can be easily taken out, and after assembling the picture tube, the chassis containing the electric circuit, the escutcheon, etc. into this empty cabinet, it is only necessary to put it back into the packaging box 1, and the cushioning materials 10 and 14 are glued together. With a drug,
Since it has already been fixed to the packaging box 1, it can be repackaged without any hassle.

Although the cushioning materials 10 and 14 are divided by the grooves 12, they protect the television receiver cabinet 6 well.

A cushioning material 16 is also arranged below the cabinet 6.

As described above, according to the present invention, a packaging box with a cushioning material can be reused, and since the cushioning material remains fixed to the packaging box with adhesive, opening and closing of the flap is easy, and packaging can be automated. becomes possible.
