折り返し線８は前記側部６の形成方法と同様に熔融接着
しつつ切断形成すればよい。In the package for rice balls shown in FIG. 5, in the first embodiment, the back member and the folded-back portion of the front surface are made of the same member in the first film 1, whereas the back member is made of the same material. And the folding member on the surface, the folding line 8
Separately, the front folding member is formed of the first film 1 and the back surface is formed of the third film 9 of the same material, and the folding line 8 is cut while melting and adhering in the same manner as in the method of forming the side portion 6. It may be formed.
前記第２の実施例は、前記第１の実施例とほぼ同様の効
果を奏し、前記第３の実施例は、前記第１の実施例に比
較して、開封用ミシン目５が全周にわたっているため、
開封をより確実に行うことができ、完全におにぎり用包
装体を２分割することもできる。The second embodiment has almost the same effects as the first embodiment, and the third embodiment has the opening perforation 5 over the entire circumference as compared with the first embodiment. Because
It is possible to more reliably open the package, and it is also possible to completely divide the rice ball package into two parts.
また、前記第４の実施例は、前記第１の実施例に比較し
て、表裏部材として形成するため、製造がより簡単にで
き大量生産に適するものである。Further, in the fourth embodiment, since it is formed as the front and back members as compared with the first embodiment, the manufacturing is simpler and suitable for mass production.
なお、包装体フィルム材料に二軸延伸ポリプロピレンと
無延伸ポリプロピレンの共押出しフィルムを用いたが、
熱熔着部を形成でき、切断部でも熔融接着が可能であれ

が用いて熱熔着部を形成してもよい。Although a co-extruded film of biaxially stretched polypropylene and unstretched polypropylene was used for the packaging film material,
As long as a heat-welded portion can be formed and melt-bonding can be performed even at a cut portion, there is no limitation on using, for example, unstretched polypropylene, polyethylene, etc. in the right place, and further, using biaxially stretched polypropylene as a film material, EVA The heat-welded portion may be formed using (ethylene-vinyl acetate copolymer), chlorinated polypropylene resin, or the like.
本考案は前記のように構成したことにより、開口部が大
きいので内部におにぎりを収納し易いとともに、収納し
た際には透明フィルムが柔らかいのでおにぎりの外周面
に密着できて内部でおにぎりが移動することがなく、し
たがって、たとえば図柄等を印刷した場合にはおにぎり
の同一部分に同一内容の表示を行える。Since the present invention is configured as described above, the opening is large, so it is easy to store the rice ball inside, and when it is stored, the transparent film is soft and can adhere to the outer peripheral surface of the rice ball so that the rice ball moves inside. Therefore, when a pattern or the like is printed, the same content can be displayed on the same portion of the rice ball.
また、透明フィルムなので外部から見ることができ、さ
らに、開封用ミシン目の部分は他の透明フィルムが積層
密着した重ね合わせ部となっているので、外部の影響、
たとえば、吸脱湿、においの吸収等を受けることがな
い。Also, because it is a transparent film, it can be seen from the outside, and since the opening perforation part is a superposed part where other transparent films are laminated and adhered, it is possible to
For example, it does not absorb or dehumidify or absorb odor.
さらに、開封時には透明フィルムが柔らかいので、開封
用ミシン目の両側を摘んで引っ張るだけで容易、かつ、
簡単、確実に開封することができるという効果を有して
いる。Furthermore, since the transparent film is soft when opening, it is easy to pick and pull both sides of the opening perforation, and
It has an effect that it can be opened easily and surely.
