［産業上の利用分野］
本発明は、口の開閉を自由に行なうことのできるチャッ
クテープ付袋の製法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for producing a bag with a zipper tape whose opening can be freely opened and closed.
［従来技術とその問題点］
チャックテープは、通常熱可塑性プラスチックにより一

このチャックテープの上からそのままヒートシールバー
を当てて熱圧着を行なうという方法が採られている。[Prior Art and its Problems] Zipper tape is usually integrally molded from thermoplastic plastic, and is usually attached to mass-produced small bags during bag making. In addition, mass-produced sachets are made of a thermoplastic plastic film or a thermoplastic plastic film bonded to the inner surface of the bag. To attach the zipper tape during bag making, insert the zipper tape between the two films,
A method has been adopted in which a heat seal bar is applied directly over the zipper tape to perform thermocompression bonding.
第８図はこの例を示し、２枚のフィルムＣ間にチャック

トシールバーｄを当ててチャックテープａの咬合部すを
押し潰しながら２枚のフィルムＣをヒートシールすると
いう方法である。Figure 8 shows an example of this, where a zipper tape a is inserted between two films C, and a heat seal bar d is applied from above as shown in Figure 9 to crush the occlusal part of the zipper tape a. In this method, two films C are heat-sealed.
しかし乍ら、上記従来例はチャックテープａをそのまま
押し潰すために、次のような問題がある。However, the conventional example described above has the following problems because the zipper tape a is crushed as it is.
ａ、 第９図からも明らかなようにチャックテープａの
特に咬合部すが厚くなるため、この部分に熱圧着力が集
中し、他の部分において圧着力が不足し、ヒートシール
が十分に行なわれず、直ぐに剥離したり、ピンホールが
発生したりする。a. As is clear from Fig. 9, zipper tape A is particularly thick at the occlusal area, so the thermocompression bonding force is concentrated in this area, and the bonding force is insufficient in other areas, making it difficult to heat-seal adequately. It may peel off immediately or cause pinholes.
ｂ、 前記欠点を解消するために熱圧着力を高めると、
今度はチャックテープａの咬合部すにおける熱圧着が過
度になり、ここにおいてピンホールが発生したり、逆に
強度が弱くなる。b. If the thermocompression bonding force is increased to eliminate the above drawbacks,
This time, the thermocompression bonding at the occlusal part of the zipper tape a becomes excessive, causing pinholes to occur there or conversely weakening the strength.

とのない製法を提案することである。[Object of the Invention] The present invention has been proposed in view of the above-mentioned problems, and its main purpose is to prevent pinholes from occurring in the heat-sealed portion including the zipper tape in bags to which zipper tape is attached, and The purpose is to propose a manufacturing method that does not weaken the seal part.
［発明の構成］ 本発明の構成は次のとおりである。[Structure of the invention] The configuration of the present invention is as follows.
ａ、 チャックテープの咬合部に一定の間隔をあけてパ

ｅ、 チャック付袋の製法。a. Punching the occlusal part of the zipper tape at regular intervals; b. Inserting the punched zipper tape between two thermoplastic plastic films or films with a heat-sealing surface formed on the inner surface; Heat seal the two films and the base part of the zipper tape, and then heat seal the two films in the direction across the zipper tape. d. Next, each bag is separated by cutting the heat-sealed portion along a line passing through the center of the punching. e. A method for manufacturing a bag with a zipper.

Note that when performing this vertical sealing 10, care must be taken that the heat sealing [1]L is sufficiently larger than the diameter R of the punched hole 6, as shown in FIG. 5, and that R<L. This is an absolute condition.

できる。[Effects of the Invention] As described above, the present invention punches and removes the interlocking part of the zipper tape before performing vertical sealing, and then heat seals the punched area. Therefore, the present invention has the following features. A bag with a zipper can be manufactured.
ａ、 パンチングにより咬合部が取り除かれているため
、たてシールを行なう際にこの咬合部が障害となって熱
圧着力が不均一になるのを防ぐことができる。a. Since the occlusal part is removed by punching, it is possible to prevent the occlusal part from becoming an obstacle during vertical sealing and making the thermocompression bonding force uneven.
ｂ、 上記ａの効果により、熱圧着力不足によるヒート
シール不良及びピンホールの発生が防止できる。b. The effect of a above makes it possible to prevent heat seal failure and pinholes due to insufficient thermocompression bonding force.
Ｃ，パンチング孔よりも巾広くたてシールを行なってい

ける気密化を完全に図ることができ、然も強度も十分で
ある。C. Since the vertical seal is made wider than the punched hole, it is possible to achieve complete airtightness at the intersection of the zipper tape and the vertical seal portion, and the strength is also sufficient.
ｄ、 チャックテープをパンチングするだけの工程付加
により本発明を実施できるので、生産性は従来と全く変
らない。d. Since the present invention can be carried out by adding only the step of punching the zipper tape, the productivity is no different from the conventional method.
