本発明は、破断帯付きのシート及びチユーブと
その製造法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to sheets and tubes with break bands and their manufacturing method.
合成樹脂フイルムで形成された袋に、飲料液
体、食料品等を収容して、販売されていること
は、周知の通りである。 It is well known that liquid beverages, foodstuffs, etc. are stored and sold in bags made of synthetic resin film.
これらの飲料液体や食料品等は、一般には、冷
蔵庫や冷凍庫に保存されるが、袋への収容の際
に、袋が合成樹脂フイルムであることからびんや
缶のように加熱殺菌できず、そのように保存され
てもなお腐敗乃至変質すると云う問題点があつ
た。 These liquid beverages and food products are generally stored in refrigerators and freezers, but when they are stored in bags, because the bags are made of synthetic resin film, they cannot be sterilized by heating like bottles and cans. Even when preserved in this way, there was a problem in that it still deteriorated or deteriorated.
また、上記の袋は、内容物を取り出すときに、
袋を破断するために鋏や庖丁等を要し、甚だ不便
であつた。 In addition, when taking out the contents of the above bag,
Scissors, a knife, etc. were required to tear the bag, which was extremely inconvenient.
本発明の目的は、期る問題点や不便を一掃する
ことにある。 It is an object of the present invention to eliminate the problems and inconveniences that may arise.
以下、図示の実施例について説明する。 The illustrated embodiment will be described below.
第１図は、第２図に示す破断帯付きの合成樹脂
シート１を用いて形成したチユーブ２を示してい
る。 FIG. 1 shows a tube 2 formed using the synthetic resin sheet 1 with breakage bands shown in FIG.
合成樹脂シート１は、第２図、第３図に示すよ
うに、上記フイルムより厚いものに押出成形し、
その一側に片寄せて連続する破断帯１２を設け、
一体成形している。 As shown in FIGS. 2 and 3, the synthetic resin sheet 1 is extrusion molded to be thicker than the above-mentioned film.
A continuous breaking band 12 is provided on one side thereof,
It is integrally molded.
該破断帯１２は、シート主部１１と異なる材質

ものでよく、また、双方の色を異ならせると、見
分けがつき易いので好都合である。 The breaking band 12 is made of a material different from that of the sheet main portion 11, for example, one is made of polyethylene and the other is made of polypropylene. Of course, the materials listed here are only examples, and various other materials may be used.It is also convenient to make the two materials different in color so that they can be easily distinguished.
斯様に形成されたシート１は、シート主部１１

て、破断帯１２を強く引くと、双方の境界部ａ，
ａ（第３図）で破断を生じる。 The sheet 1 formed in this manner has a sheet main portion 11
and the fracture zone 12, but due to their different materials, the bonding force between them is weak. Therefore, when the fracture zone 12 is strongly pulled, the boundary portion a,
A break occurs at point a (Figure 3).
チユーブ２は、上記シート１を用いたものであ

閉塞１０２して、袋状に形成し、に、その袋状
のものに内容物を充填して、開口端を前回同様に
一字状につぶして溶着閉塞１０３し、内容物を封
入する。 The tube 2 uses the sheet 1 described above, and as shown in FIG.
A state in which the sheet 1 is cut by a small length l, the end of the breakable band 12 is made to protrude, and the end forms the tab piece 121, and the sheet 1 is bent to make the tab piece 121 protrude. In step 101, the two ends are polymerized and welded to form a cylinder, in which the end of the cylinder on the side where the break band 12 is located is crushed into a linear shape and closed by welding 102 to form a bag shape; The bag-like material is filled with the contents, and the open end is crushed into a linear shape as before, and the contents are sealed by welding and closing 103.

帯１２との間で破断が生じ、開封開口できる。 The tube 2 shown above has a considerable wall thickness in the sheet 1, so it can be heat sterilized when filling the contents, and after being sealed, the tab piece 1
21 and pull it around, a break occurs between the sheet main body 11 and the breaking band 12, and the seal can be opened.

ある。 According to the present invention, a very good tube of any shape can be obtained, and since the tube uses a synthetic resin sheet, it has an appropriate wall thickness and is strong.
When storing liquid beverages, foodstuffs, etc., it can be heat sterilized, and like bottles and cans, it will not rot or deteriorate even during long-term storage, and can be cooled or frozen while stored in the tube, or as appropriate. It can be heated and served for drinking and eating. In addition, when taking out the contents, the bag can be opened simply by holding the tab and pulling it, and there is no need for scissors or a knife, making it very convenient and useful.
