（産業上の利用分野）
本発明は一端または両端が開口している包装材の該開口
部が容易に開閉することのできる包材に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a packaging material that is open at one end or both ends of which the opening can be easily opened and closed.
（従来の技術）
従来、密封可能でかつ必要に応じて開閉を自由にするこ

れる。(Prior art) Conventionally, synthetic resin packaging materials that can be sealed and can be opened and closed as needed include tubular films with both ends open and three sides closed [usually one part is one part]. There is a cylindrical packaging material that is a bag, and the former is especially used when packaging a group of products of irregular shape or length, such as large fish, vegetables, trees, etc. In addition to being used for long scrolls such as carpets.
さて、これら筒状包材の開［１部の密封のためには該開
「１部を束ねて紐でくくったり、輪ゴム巻いたりまた束
ねられた開口部そのものを結んだり、その他開閉の繰り
返しは難しいがヒートシールすることもある。Now, in order to open and seal one part of these cylindrical packaging materials, it is necessary to bundle one part and tie it with a string, wrap it with a rubber band, tie the bundled opening itself, or repeat opening and closing. Although it is difficult, you can also heat seal it.

通常の袋などの筒状包材の出現が望まれてきた。However, these conventional methods have good sealing performance, but are complicated by the need to be careful about storing the untied string to prevent it from being lost, and are difficult to remove the tightened rubber band. In addition to damaging the opening of the bag when untying the tied opening, there is also the difficulty of carrying a heat sealer everywhere for sealing. The emergence of cylindrical packaging materials such as films and regular bags has been desired.

し、本発明を完成した。(Means for Solving the Problems) As a result of intensive research to obtain a cylindrical packaging material having the above characteristics, the present inventor found that this can be achieved by attaching thin metal wires to a synthetic resin film using a special tape. They discovered this and completed the present invention.

。以下、本発明の詳細な説明する。That is, the gist of the present invention is that a plastic thin metal wire is interposed between a synthetic resin cylindrical film and at least one longitudinally tearable narrow tape disposed along its generatrix, and the thin metal wire The present invention relates to a cylindrical packaging material which is easily opened and closed and is fixed to the film by adhesion between the film and the narrow tape. The present invention will be explained in detail below.

That is, in addition to the most common polyethylene film, polypropylene film, polyester film, polyvinyl chloride film, etc., nylon film, vinylon film, polyvinylidene chloride film, etc. are suitable.

It also includes flat films glued together into a tubular shape.

リプロピレンの延伸フィルムが好適に用いられる。These longitudinally tearable narrow tapes arranged along the generatrix of the film may be made of cellulose paper, synthetic paper, or synthetic resin film, but in the case of cellulose paper, the constituent fibers are oriented in a certain length direction. The same can be said for synthetic paper made from fibers. However, synthetic paper made from film or synthetic resin film must be stretched in the longitudinal direction. Due to the orientation of these fibers or the stretching process of the film, when trying to separate the thin metal wire from the cylindrical film as described below, the narrow tape is easily torn vertically and the thin metal wire of the desired length is separated from the cylindrical film. Separately, that part is used for fastening. Suitable materials for such a tape include cellulose paper, cellophane paper, polystyrene synthetic paper, and stretched polypropylene film.
これ等テープを筒状フィルムに接着する方法は通常知ら

ほか熱接着による方法ももちろん好適である。As for the method of adhering these tapes to the cylindrical film, commonly known methods are sufficient, and in addition to methods using adhesives and pressure-sensitive adhesives, methods using thermal bonding are of course suitable.

ない。A thin plastic metal wire is arranged between this tape and the cylindrical film, and when the thin metal wire is wrapped around an object, it remains wrapped, and can be easily rewound in the original direction if necessary. refers to a thin metal wire that can be plastically deformed without breaking, and specifically, a mild steel wire that is usually used for tying articles or manufacturing wire mesh is suitable. Since the above-mentioned wire rod is usually wound with a fingertip, it is difficult to use a wire rod with high rigidity. Also, it is not suitable to wrap a material with high elasticity because it cannot be fixed. For example, piano wire cannot be used. In short, unless it is plastically deformable, the effect of sealing by gathering the open L1 portion of the film together and fixing it with the wire wrapped around it will not be achieved, as will be described later.

る。At least one of these wires is arranged along the generatrix of the cylindrical film, but if there are too many wires, it is not preferable that the sealing performance is deteriorated. One bottle is sufficient unless the item to be packaged is large.
次にこれ等金属細線を細幅テープで筒状フィルムに取り
付ける方法について述べる。Next, a method for attaching these thin metal wires to a cylindrical film using narrow tape will be described.

ムに接着させる方法が便利である。As mentioned above, a cylindrical film can be easily obtained by the inflation molding method or by forming a flat film into a cylindrical shape, but there is a method in which the thin metal wire is introduced between the narrow tape at the same time as it is bonded to the cylindrical film. In addition, thin metal wires are interposed between two narrow tapes in advance and both tapes are pasted together to form a thin metal wire-containing narrow tape, and the tape is made into a cylindrical film or a flat film before being made into a cylindrical shape. It is convenient to attach it to the

ものが通常の長さである。Next, how to use the cylindrical film with thin metal wires made in this way will be explained. Grasp the film part and the thin metal wire part of the opening of the cylindrical film separately,
When pulled in the opposite direction, the thin metal wire tears the narrow tape and separates from the tubular film like a tree branch. This branch-like portion is made long enough to wrap tightly around the opening of the cylindrical film. Depending on the length and size of the cylindrical packaging material, the usual length is 5 to 1 cm (about 1 cm or 15 to 20 cm).

うとよい。There are no particular restrictions on how to wrap the branch-like thin metal wire, but it is best to grasp the part just before it splits into branches with one hand, gather the openings of the cylindrical film together, and wrap the branch-like part. . In addition, in order to prevent the narrow tape containing thin metal wires from being gradually torn, it is preferable to bend part of the root toward the original direction before wrapping the branch-like portion.

目的は同様に達成される。Next, embodiments of the present invention will be described using the drawings. FIG. 1 shows a plan view of the first embodiment of the present invention, in which a high-density polyethylene tubular film 2 has a narrow metal wire 4 made of high-density polyethylene stretched approximately twice as long and having longitudinal tearability. It is attached by thermally adhering the tape 3. The tubular film 2 has a bottom portion 5 formed by heat sealing, and the opposite side is open [1 portion 6] to form the cylindrical packaging material 1. . FIG. 2 shows a view taken along the line A and A in FIG. 1. Figure 2 below 1st
The same parts as in the figure are given the same reference numerals. FIG. 3 shows a second embodiment in which a tape 7 made by sandwiching a thin metal wire between two longitudinally split narrow tapes and pasting them together is adhered to the end of a folded tubular tape section. The tape is the fourth
As shown enlarged in the figure, a thin metal wire 4a is sandwiched between narrow tapes 3a, 3a. Although the locations where the thin metal wires are separated are different in the case of FIG. 2 and the case of FIG. 3, the object of the present invention is achieved in the same way.
