[Background of the idea]

For example, a tape cassette made of paper or soft resin that stores a video tape cassette. The storage case (hereinafter referred to as the sleeve) includes the upper plate, lower plate, back plate, and each of the above-mentioned plates. It is constructed by bending, overlapping, and joining the side plate portions extending from the side plate portion. And this stream The leaves are sold with the outside wrapped in a packaging material made of polypropylene film. There is.

0003 This packaging material has the product Names and various designs are printed on them. In the packaging process, the packaging material is folded. Polymerize by folding the parts, and put this polymerized part in a packaging device such as a heat block. Packaging is carried out by heat welding. By the way, the overlapping part where the plurality of side plate parts of the sleeve are overlapped and joined is the circumferential part. Because it protrudes somewhat compared to the surrounding area, it may be pressed strongly during transportation, etc. If it is rubbed, the printing material such as ink printed on the packaging material may come into direct contact with it. There is a risk that it will be transferred to the overlapping part of the sleeve, reducing the commercial value. Therefore In order to prevent this transfer, polypropylene varnish (hereinafter referred to as P) is applied to the entire surface of the printing material. A method of printing (coating) P varnish has been proposed.

0004 However, due to the action of the PP varnish, the area printed with this PP varnish is There is a new problem in that the degree of thermal welding of the packaging material is reduced.

Continuously construct a long storage case (hereinafter referred to as sleeve) for one pack of B. The finished product is then rolled into a roll. In addition, the range shown by the imaginary line in FIG. This corresponds to each of the constituent board surfaces.

[0009] 1, the inner surface of the transparent packaging material A, that is, the surface of the sleeve B to be wrapped, is in direct contact with the inner surface of the transparent packaging material A. This is a printed part that covers almost the entire surface that is touched, and is printed with various color inks, etc. Product names and various designs are printed using printing materials. That is, this printing section 1 The product name and various designs depicted on the screen can be seen from the outside through a transparent film. configured so that it is possible.

0010 2 is a varnish printing section, and the position where varnish is printed is determined using this packaging material A. Upper right side plate part B of sleeve B to be packaged₃, lower plate right side plate part B₆, back panel right side panel B ₉ and upper left side plate part B₂, Lower left side plate part B_Five, Back left side board part B₈are each heavy This is the position corresponding to the overlapping part M that is joined. That is, in this polymerization part M Because the ends of each plate overlap and swell slightly more than the surrounding area, film packaging is not recommended. Pressure contact and abrasion with material A are likely to occur. Therefore, the film packaging caused by this Prevents the trouble of the printing material on the side of the packaging material A being transferred to the overlapping part M of the sleeve B. This is why varnish is printed on it.

B is a sleeve that is packaged using the film packaging material A described above. As shown in FIG. 2, this sleeve B consists of _a sheet material made of paper or soft resin that extends from the upper plate part B ₁ , the upper left side plate part B ₂ extending from the upper plate part B 1 , and the upper plate part B ₁ .
