Abstract

PURPOSE:To enable automatic filling of a bal provided with an opening means by a method wherein an opening and closing device is bent into a U-shape to have a male groove and a female groove engaged, and t the same time constitution is made so that one of the lower ends of this opening and closing device is sealed onto one of the upper ends of the bag. CONSTITUTION:On an opening and closing device, a male groove 5 and a female groove 6 are molded in parallel by extrusion on the same plane of the tape 4, and this tape 4 is two-folded at the middle of the tape to have the male groove 5 and the female groove 6 engaged with each other. A part of the lower end 7 of an opening and closing device 3 is inserted into a part to be an opening of a bag 1, and one of the lower ends 8 is heat-sealed onto one of the upper ends 8 of the bag 1. A hopper 11 is inserted into this mouth 2 to fill contents 12 in the bag. After this filling, both sides of the mouth 2 of the gag 1 is pressed between a cooling bar 10 and a heating bar 9. The unsealed side of the bag 1 is heat-sealed with this pressing. A film to be used is not specially limited as far as the melting point of the inner of the bag 1 and the outer of the tape 4 is lower than that of the outer of the bag 1 and the inner of the tape 3, respectively.

On the other hand, the tape 4 of the opening/closing device 3 is bent into a U-shape and has PE 4' on the outside and PP (polypropylene) 4'' on the inside. Of course, the above configuration is just an example, and other materials may be used.

First, the opening/closing device is formed by extruding strips 5 and male strips 6 parallel to the same surface of tape 4, and this tape 4 is bent in half in the middle. The strips 5 and male strips 6 are interlocked. On the other hand, the packaging body 1 is constructed by folding two films or two films into a 0-shape, and a part of the lower edge 7 of the opening/closing device 3 is inserted into the part of the packaging body 1 that is to become the opening. One of the lower edges 7 is heat-sealed to one of the upper edges 8 of the packaging body l. When performing this heat sealing, a heat bar 9 is placed on the side to be heat sealed and a cooling bar l is placed on the other side so that only the lower and upper edges on the negative side are heat sealed.
O is configured to apply pressure, and as a result, only one of the lower edges 7 and one of the upper edges 8 are heat-sealed.

After the day 2 is opened as shown in the figure, the hopper 11 is inserted into the day 2 as shown in FIG. 4, and the contents 12 are filled as shown in FIG. After this filling is completed, a cooling bar 10 is placed on both sides of the opening 2 of the main body 1, and a heat bar 9 is placed on the previously sealed side, and a heat bar 9 is placed on the unsealed side, as shown in FIG. cooling bar on both sides 10
and is compressed by the heat bar 9. This clamping pressure heat-seals the unsealed side.

の融点は低いことが条件である。In addition, the above heat sealing requires that the inner surface of the bag body l be made of PE, the outer surface of the tape 4 side be made of PE, and that the outer surface of the packaging body l be made of PE.
Since the inner surface of the tape 4 is made of PP, only the inner surface of the packaging body 1 and the outer surface of the tape 4 are heat-sealed due to the difference in their melting points, and the inner surface of the tape 4 is not heat-sealed. In the present invention, the material film is not particularly limited, or as is clear from the above, the inner surface of the packaging body 1 and the tape 4
The outer surface of the tape 3 must have a lower melting point than the outer surface of the packaging body 1 and the inner surface of the tape 3.

［本発明の効果］ 本発明は以上の如き構成から成るため、次の如き効果を
奏することかてきる。[Effects of the Present Invention] Since the present invention has the above-described configuration, the following effects can be achieved.

封か可能である。84 The opening/closing device consists of a piece of tape, which is folded in two and sealed in advance to the opening of the bag, and the other is left unsealed, so the opening of the bag is free. It is possible to fill the bag with the contents by inserting a hopper, and finally to seal the bag by heat-sealing the unsealed portion.

この結果、従来のように手作業で袋の口を開いて内容物
を充填するという必要かなく、一連の工程を全自動化で
きる。As a result, there is no need to manually open the bag and fill it with the contents, as in the past, and the entire process can be fully automated.

６１袋は、開閉装置付の状態においてその口は開いたま
まであるので、第３〜７図に示したような工程を経て簡
単に内容物の充填がてきると共に従来の袋に比較して製
袋コストも安い。The mouth of the 61 bag remains open when it is equipped with an opening/closing device, so it is easy to fill the contents through the steps shown in Figures 3 to 7, and it is manufactured more easily than conventional bags. Bag cost is also low.
