本発明は菓子、漬物の販売時等に使用される合成樹脂シ
ート等を用い六マチ付袋の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a six-gusset bag using a synthetic resin sheet, etc., which is used when selling sweets and pickles.
従来のこの種の袋の製造方法は次のとおりである。片面
熱溶着性シート１０、たとえばナイロン膜の一面に低温
で軟化するポリエチレンまたはポリプロピレンを接合し
たものを用い、このシート１０の両側端１２を熱溶着す
ることにより全体を筒状に形成し、この両側を内側に折
畳みマチ１４を形成する（第１図、第２図参照）このと
き、マチ１４の端部１６を熱溶着してもよい０次に第３
図に示すように、マチ１４を折畳んだ状態でヒートパー
を押圧し、底部１８を溶着し、底部１８よシわずか下方
位置２０を切断し袋２２を完成する。The conventional method for manufacturing this type of bag is as follows. A single-sided heat-fusible sheet 10, for example, a nylon film bonded to one side of polyethylene or polypropylene that softens at low temperatures, is used, and both ends 12 of this sheet 10 are heat-welded to form a cylindrical shape as a whole. is folded inward to form the gusset 14 (see Figures 1 and 2).At this time, the end portion 16 of the gusset 14 may be heat welded.
As shown in the figure, with the gusset 14 folded, a heat pack is pressed, the bottom part 18 is welded, and a position 20 slightly below the bottom part 18 is cut to complete the bag 22.
この袋２２金使用すると第４図に示すように底部１８の
隅部２４Ｆ′ｉ互に離れ、開いてしまう。When this 22-carat gold bag is used, the corners 24F'i of the bottom 18 separate from each other and open as shown in FIG.
これにこの隅部２４においては、マチ１４の熱易溶性を
有しない表面が互に接するよう折畳まれるので、底部１
８溶着時に熱を加えられても隅部どうしは溶着されない
からである。このためこの袋２２では輸送・販売過程に
おいて、この隅部２４が折れ曲がシ美観を損ね、商品価
値を低下させることが多い。In addition, at this corner 24, the surfaces of the gusset 14 that are not easily soluble in heat are folded so that they touch each other, so the bottom 1
8. This is because even if heat is applied during welding, the corners will not be welded together. For this reason, the corners 24 of this bag 22 are often bent during the transportation and sales process, spoiling the aesthetic appearance and reducing the product value.
本発明はこのような不都合を解消するため、底部の隅部
が互に接着された袋を製造するものでめる。In order to solve this problem, the present invention provides a bag whose bottom corners are glued together.
すなわち本発明方法は底部溶着前に底部溶着部両側に切
込みを形成する工程を設け、底部溶着時にこの切込みか
ら袋内面の熱溶着性物を浸出させ底部の隅部を互に接着
するものである。That is, the method of the present invention includes a step of forming cuts on both sides of the bottom welding part before welding the bottom, and when welding the bottom, the heat-weldable substance on the inner surface of the bag oozes out from the cuts, and the corners of the bottom are bonded together. .
次に図を参照しつつさらに詳しく本発明方法を説明する
。前述の従来例と同様にシート１０の両側端１２を熱溶
着し、全体を筒状とし、マチ１４を折畳み、マチの端部
１６を溶着した後、第５図に示すように、底部溶着部両
側に切込み２６′ｆｒ形成する０次に断面く字状のヒー
トバーを用い底部２８全溶着し同時にこの溶着部を製綱
方向の断面形かく字状となるよう形成し、底部２８より
わずか下方位置３０を切断し、袋３２ｔ−完成する。Next, the method of the present invention will be explained in more detail with reference to the drawings. As in the conventional example described above, the both ends 12 of the sheet 10 are heat welded to make the whole into a cylindrical shape, the gusset 14 is folded, and the ends 16 of the gusset are welded. As shown in FIG. The bottom 28 is entirely welded using a heat bar with a 0-order dogleg-shaped cross section with cuts 26'fr formed on both sides, and at the same time, this welded part is formed to have a dogleg shape in cross section in the rope making direction, and the welded part is formed at a position slightly below the bottom 28. 30 is cut to complete the bag 32t.
この袋３２では使用時に、第７図に示すように、底部２
８の隅部３４ｔｊ表裏が離れることはなく結合した状態
となる。これは底部２８溶着時に切込み２６から袋３２
内面の熱溶着性物が浸出し隅部３４の表裏を接着するか
らである。When this bag 32 is used, as shown in FIG.
The corner portion 34tj of 8 is in a state where the front and back sides are not separated and are joined together. This is from the notch 26 to the bag 32 when the bottom part 28 is welded.
This is because the heat-fusible material on the inner surface adheres the front and back sides of the seepage corner 34.
このためこの袋３２では輸送・販売過程中にこの隅部３
４が折れ曲がシ商品価値を低下させることはない。Therefore, in this bag 32, this corner 3 is
4. Bending does not reduce the product value.
ま友、上記実施例のように底部２８の製綱方向の断面形
全く字状に形成すると、隅部３４の曲げ剛性が大きくな
るので、隅部３４の折れ曲がりはより確実に防止される
。By the way, if the cross section of the bottom part 28 in the rope making direction is formed into a straight shape as in the above embodiment, the bending rigidity of the corner part 34 will be increased, so that bending of the corner part 34 can be more reliably prevented.
本発明は以上のように切込みを形成するという単純な工
程を付加するだけで、上記のすぐれた効果を得ることが
できるので、実施化が容易であシ、菓子等の包装用とし
て好適である。The present invention can obtain the above-mentioned excellent effects by simply adding the simple step of forming the incisions, so it is easy to implement and is suitable for packaging confectionery, etc. .
