【考案の詳細な説明】
本案は合成樹脂薄膜筒１の底部を加熱溶着により密封２
し、かつ同密封部２の内部に軽加熱による対向内面軽溶
着部３を形威した包装用袋に関するものである。[Detailed explanation of the invention] The present invention is to seal the bottom of the synthetic resin thin film cylinder 1 by heat welding 2.
The present invention also relates to a packaging bag in which a light welded part 3 on the opposing inner surface is formed by light heating inside the sealed part 2.
合成樹脂薄膜筒１は第６図に示すように中密度ポリエチ
レンシート４、高密度ポリエチレンシート５、サラン６
並びに２軸延伸ポリプロピレン７等の巻取密着重層シー
ト８を２層重ねて矢印ａ方向に間欠移行させ停止時加熱
スタンプによって側縁９，９を加熱溶着し切断線すに沿
って切断し上記薄膜筒１が形成される。As shown in FIG. 6, the synthetic resin thin film tube 1 includes a medium density polyethylene sheet 4, a high density polyethylene sheet 5, and a saran 6.
Then, two layers of rolled up close-contact multilayer sheet 8 made of biaxially oriented polypropylene 7 or the like are stacked and moved intermittently in the direction of arrow a, and when stopped, the side edges 9, 9 are heated and welded with a heating stamp, and cut along the cutting line to form the thin film. A cylinder 1 is formed.
又上記停止時に同筒１の底部加熱スタンプ１０によって
底部が加熱溶着される。Further, when the cylinder 1 is stopped, the bottom part is heated and welded by the bottom heating stamp 10 of the cylinder 1.
上記スタンプ１０は第１図に示すように薄膜筒１の３個
分の長さを有し、同スタンプ１０に１個分の短スタンプ
１１を第１図および第２図に示すように並設し、上記矢

よび停止させてその停止毎に上記スタンプ１０．１１を
スタンプ台１２上の筒底部に圧下し筒底部を長スタンプ
１０により３回、短スタンプ１１により１回加熱圧着し
、長スタンプ１０により強力密封部２を形威し、かつ短
スタンプ１１により上記対向内面軽溶着部３を形成する
ことができる。The stamp 10 has a length equivalent to three thin film tubes 1 as shown in FIG. 1, and one short stamp 11 is arranged in parallel with the same stamp 10 as shown in FIGS. Then, the intermittent transfer length in the direction of the arrow a is set to the length of one piece, and the transfer is made and stopped three times, and at each stop, the stamps 10 and 11 are pressed down onto the bottom of the cylinder on the stamp stand 12, and the bottom of the cylinder becomes a long stamp. 10 and once with the short stamp 11, the long stamp 10 forms the strong sealing part 2, and the short stamp 11 forms the light welding part 3 on the opposing inner surface.
尚図中１３で示すものは短スタンプ取付螺子、１１′は
異形短スタンプ、３′は異形短スタンプ１１′による軽
溶着部（第４図）である。In the figure, numeral 13 indicates a short stamp mounting screw, 11' indicates an irregularly shaped short stamp, and 3' indicates a light welded portion (FIG. 4) by the irregularly shaped short stamp 11'.
従って第３図、第４図に示す袋の上端開口部１′を吸引
により開口し、大根の漬物等の収容物１４を投入すると
同収容物１４はその重量によって第７図に示すように筒
１内を下降し軽溶着部３に近接する（第８図）、そして
同経溶着部３を押し開いて第９図に示すように密封部２
によって支持される。Therefore, when the upper end opening 1' of the bag shown in FIGS. 3 and 4 is opened by suction and the stored object 14, such as pickled radish, is thrown in, the stored object 14 will become cylindrical as shown in FIG. 7 due to its weight. 1 and approaches the light welded part 3 (Fig. 8), and then pushes open the light welded part 3 to close the sealing part 2 as shown in Fig. 9.
Supported by
その後開口部１′を加熱溶着密封して包装を終了する。Thereafter, the opening 1' is sealed by heat welding to complete the packaging.
本案は上述のように構成したので開口部１′から投入し
た収容物１４の下端がその重量による下降によって密封
部２に衝撃的に到達することがない。Since the present invention is constructed as described above, the lower end of the stored object 14 introduced through the opening 1' does not reach the sealed portion 2 shockingly due to its downward movement due to its weight.
即ち対向内面軽溶着部３を押し開くため下降重量による
衝撃が緩和され底部密封部２の破袋を防止し得る便益が
ある。That is, since the opposing inner surface lightly welded portion 3 is pushed open, the impact caused by the descending weight is alleviated, which has the advantage of preventing the bottom sealing portion 2 from breaking.
