価に製造する方法に関するものである。Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a new method for manufacturing packaging bags, and more specifically, the process from the production process of bags to the dismantling after containing the contents, and furthermore, from disassembly to dismantling the contents. The present invention relates to a method for inexpensively manufacturing a packaging bag that is free from the risk of contamination with foreign matter during the process of discharging it and is easy to seal and disassemble.
「従来技術と問題点」
従来、合成樹脂等の粉体、粒状物等を収容するための包
装袋としては、クラフト紙、クラフト紙と合成樹脂との
ラミネート又は両者を２〜３重に重ねてなる包装袋が広
く用いられている。"Prior Art and Problems" Traditionally, packaging bags for storing powders and granules such as synthetic resins have been made of kraft paper, a laminate of kraft paper and synthetic resin, or two or three layers of both. Packaging bags are widely used.
しかし乍ら、従来の包装袋にあっては、上記クラフト紙
、クラフト紙と合成樹脂とのラミネート等のシート状物
を適当な大きさに裁断し、接着して袋を製造するため、
作業環境に存在するホコリ、ゴミ、毛羽やクラフト紙や
ラミネートの裁断片等を抱き込み、これらが内容物中に
混入することが避けられない、また該袋を解体して解体
して内容物を排出する場合にも、同様にホコリや裁断片
等の混入を避けることは不可能である。However, in the case of conventional packaging bags, the bags are manufactured by cutting the above-mentioned sheet materials such as kraft paper, laminate of kraft paper and synthetic resin, etc. into appropriate sizes and gluing them together.
It is unavoidable that dust, dirt, fluff, shredded pieces of kraft paper or laminate, etc. present in the work environment will be trapped and mixed into the contents, and that the bag must be dismantled and disassembled to remove the contents. Similarly, when discharging, it is impossible to avoid contamination with dust, shreds, etc.
一方において、近年、ホコリや裁断片等の異物に対する
要請は益々シビアーとなっており、肉視不可能なものや
常套の検出手段では検出不可能なものまでクレームの対
象となってきている。例え □ば、ＭＢＳ樹脂に対す
るクレームの９０％以上が異物クレームであり、その中
でも袋に起因する異物クレームが５０％を越える状況と
なっている。On the other hand, in recent years, requirements regarding foreign substances such as dust and shreds have become increasingly severe, and even items that cannot be seen with the naked eye or cannot be detected by conventional detection means are becoming the subject of claims. For example, more than 90% of complaints regarding MBS resin are foreign matter complaints, and among these, foreign matter complaints due to bags account for more than 50%.
そして、かかる異物混入に対する要請は、医薬や食品等
の分野において特に顕著である。The need to prevent such foreign matter contamination is particularly significant in the fields of medicine, food, and the like.
「問題点を解決するための手段」
本発明者はかかる実情に鑑み、上記の如き問題点を解消

造方法を内容とするものである。That is, the present invention provides an outer bag formed from a sheet material such as kraft paper or a laminate of kraft paper and synthetic resin.
One opening of a synthetic resin cylindrical body having an overlong part that is appropriately longer than the outer bag and openings at both ends is folded at least as many times as the contents are sealed approximately by the length of the overlong part. The method of manufacturing a packaging bag is characterized in that the bag is charged in an open state, and then the outside of the inner bag in the vicinity of another opening and the inside of the outer bag are bonded together.

包装袋（Ａ）が製造される。As shown in FIG. 3, after inserting the cylindrical body (4) into the outer bag (1) with its extended portion (5) folded an appropriate number of times, the cylindrical body (4) ) and the outer bag (1) are glued at the upper part (6) (6°) and folded to form an extended part (5).
A packaging bag (A) is produced in which an inner bag (7) having a bottom is inserted into an outer bag (1).

応じて適宜決定すれば良い。As mentioned above, the extended portion (5) forms the bottom of the inner bag (7) in an appropriately folded state while the contents are being accommodated, and seals the contents (8), while also forming the outer bag ( 1) It serves to cover the area around the opening and prevent paper pieces, lint, etc. generated when dismantling the outer bag, as well as dirt and dust present in the work environment, from getting into the contents. Excessive part (
5) The length and number of folds are determined so that both of the above functions are achieved. Although it depends on the particle size, specific gravity, etc. of the contents (8) and cannot be determined unconditionally, the length is usually about 5 to 50 cm, and the number of folds is at least 2 times, preferably 3 times or more. The upper limit of the number of times of folding is about 5 times. If the overextended portion (5) is too small, it will be difficult to perform the folding and covering work, and the bending and covering will be incomplete during content discharge, resulting in an insufficient effect of preventing foreign matter from entering. It becomes difficult to do so, and the effect of preventing foreign matter contamination does not increase any further.
On the other hand, if the number of times of folding is too small, the sealing effect of the contents will be insufficient, and if it is too many, it will take time to fold and the workability will be poor. All you have to do is decide.

ができる。In the above, an example was shown in which the outer bag (1) was sealed with a tape seal (including a thread seal), but other means such as a hook-and-loop fastener that can be disassembled with one touch can also be used, and by using this structure, Both the outer bag and the inner bag can be dismantled without the use of tools, greatly improving work efficiency. It goes without saying that the purpose of preventing shopping items from being mixed up in the present invention can be achieved even without using these one-touch dismantling means for the outer bag. The packaging bag obtained according to the present invention can accommodate not only synthetic resins but also all powdery materials, granular materials, and the like.
「作用・効果」

。"Action/Effect" As mentioned above, according to the present invention, from the bag manufacturing process to disassembly,
It is possible to provide a packaging bag that completely meets the request for foreign matter removal without the risk of foreign matter getting mixed in until it is discharged, and also,
Since the bottom of the inner bag can be formed by simply folding it, processes such as heat sealing can be omitted and it can be manufactured at low cost.
