本考案は穀粉、セメント、配合飼料、砂糖、塩
等を充填収納する重包装袋に関する。[Detailed description of the invention] [Field of industrial application] The present invention relates to a heavy packaging bag for filling and storing grain flour, cement, compound feed, sugar, salt, etc.
従来、重包装袋はクラフト紙を用いて扁平筒を
形成し、次いで当該扁平筒の開口縁部を重ね折り

免れないものであつた。
However, when filling the contents of such conventional heavy packaging bags (especially when using an automatic filling machine), it is not possible to sufficiently deaerate the air that is introduced into the bag together with the contents. The drawback is that the heavy packaging bag expands to its maximum capacity before being filled with a predetermined amount.
そこで、本考案者は斯かる従来の欠点を解消し
た重包装袋を提供すべく種々検討を重ねた結果、
内容物充填中の脱気を行い得る本考案重包装袋を
案出したものである。 Therefore, the inventor of the present invention has conducted various studies in order to provide a heavy-duty packaging bag that eliminates these conventional drawbacks.
The present invention has devised a heavy-duty packaging bag that can perform deaeration during filling.
すなわち、本考案は内袋を有する袋筒１開口部

That is, the present invention makes a notch 2 in at least one place on the upper side of the opening of a bag tube 1 having an inner bag, and then folds both left and right ends inward while widening the opening of the bag tube 1, so that at least one end A pentagonal folding piece part (5 and/or 6) is formed with the remaining piece 2S as the non-inward folding part, and then the back piece 4 and the front piece 3 are sequentially folded to form a square bottom part. A bag body 1 in which a non-laminated interlayer part 7 communicating to the outside is formed between the pentagonal folding piece part (5 and/or 6), the front piece 3 and the back piece 4, and the part where the folding piece 9 is not present. This is a heavy packaging bag consisting of decorative paper 8 made of kraft paper attached to the folded corner bottom of the bag body 1.
本考案重包装袋に於ける内袋は、通気性のある

樹脂フイルムにクラフト紙をラミネートした素材
にて製袋したものを云う。 The inner bag of the heavy-duty packaging bag of the present invention may be an air-permeable inner bag made of kraft paper, but depending on the contents, an inner bag made of synthetic resin film is preferable. Here, the term "synthetic resin film inner bag" refers to bags made only from synthetic resin film and bags made from synthetic resin film laminated with kraft paper.
尚、本考案に於て合成樹脂フイルム製内袋とし

入を防止し得、特に有効な結果が得られる。 In addition, when implementing the present invention as an inner bag made of synthetic resin film, if an appropriate number of slits are formed at the bottom of the folded corners, air can be vented more effectively during filling of the contents. At the same time, after the filling is completed, the gap between the slits is closed and the slit becomes like a simple line, so that moisture can be prevented from entering the bag after filling, and a particularly effective result can be obtained.
ここに合成樹脂フイルムとしては防湿性ある合

することもできる。 As the synthetic resin film, any moisture-proof synthetic resin film can be used, but medium-low pressure films such as polyethylene film (15 μm) are suitable, for example. In carrying out the present invention, the outer bag is made of breathable kraft paper, etc., as in the past, and the so-called two-layer bag structure is basically used. A multilayer bag such as a three-layer bag structure with an innermost bag may also be used.
次に、本考案に於ては、重ね折り角底部の端部
積層部に外部に通じる非積層間隙部が必須要件と
される。 Next, in the present invention, a non-laminated gap portion communicating with the outside is an essential requirement in the end laminated portion of the folded corner bottom portion.
更に、本考案に於ては、重ね折り角底部に貼着

て袋耐１が構成されるものである。 First, a bag tube 1 made of the material with upper and lower openings is made into a flat tube as shown in FIG. Enter 2.
The length of this cut 2 can be appropriately selected depending on the width of the non-laminated gap to be obtained, but it is usually suitable to be about one third of the distance from the upper side to the valley fold line c. Next, while expanding the upper opening edge of the bag tube 1, fold both left and right ends inward along the mountain fold lines a and b, and fold only the surface portion downward along the valley fold line c. As shown in FIG. 2, a pair of pentagonal fold-in pieces 5 and 6 are formed at the left and right ends of the front piece 3 and the back piece 4. Therefore, the lower parts of the back piece 4 and the left and right pentagonal folding pieces 5 and 6 are folded inward along the valley fold line d by more than 1/2 of the short width of the back piece 4, and the third
The state is as shown in the figure. Next, the tops of the surface piece 3 and the left and right pentagonal fold-in pieces 5 and 6 are similarly aligned along the valley fold line e, and are 1/1/2 of the width of the short side of the surface piece 4.
By folding two or more parts inward and stacking them oppositely on the folded part of the previous back part 4,
As shown in the figure, an overlapping and folded corner bottom part is formed, and each laminated part except for the non-laminated gap part 7 is properly glued and fixed to form the bag holder 1.

も良いこと論を埃つまでもない。 In addition, although the example explained above is an example in which a non-laminated gap portion is provided in the laminated portions at both ends of the folded corner bottom, the non-laminated gap portion may be provided only in the laminated portion at one end portion. I don't even know what to say.

The decorative paper 8 may be pasted in such a manner that after filling a separate decorative paper with the contents, it is covered and pasted on the bottom of the folded corner. Good results can be obtained by leaving it as an attached part and pasting it together with other parts to overlap and integrate it with the bottom part of the folded corner. The unattached portion of this decorative paper 8 is as follows:
Not only the non-laminated gap covering piece 8a but also the content filling opening covering piece 8b, if a content filling opening is formed at one end of the folded corner bottom, are configured as an unattached part. is preferable. In this case, it is extremely advantageous to apply a Holtomet type adhesive to the adhesive surface of the unattached portion in advance for adhesive sealing after filling the contents.

In the end laminated part of the folded corner bottom obtained in this way, the cut remaining piece 2S is not folded inward at all, unlike the pentagonal folded pieces 5 and 6, as a non-inward folded part. As a result, as shown in FIGS. 5 and 13, due to the absence of the folded piece 9, a portion corresponding to the thickness of the remaining cut portion 2S, in other words, a portion corresponding to the thickness of the pentagonal folded piece portion 6 is removed from the outside. A non-laminated gap 7 is formed between the front piece 3 and the pentagonal fold-in piece 6 as well as between the back piece 4 and the pentagonal fold-in piece 6.

Due to the presence of the inner bag made of synthetic resin film, this invention provides an extremely excellent moisture-proofing effect, and as a result of the non-laminated gap 7 releasing air during filling to the outside, it is possible to prevent heavy packaging bags from being filled with air. Expansion can be prevented. Moreover, when the non-laminated gap 7 is filled with the contents, the laminated part is compressed due to the filling of the contents, and as a result, the gap 7 itself is compressed and closed, and there is a risk of moisture intrusion through the gap 7. This is hardly recognized. Furthermore, as a result of the decorative paper piece 8a made of kraft paper being stuck to the non-laminated gap 7 after filling with the contents, the closure and reinforcement of the folded corner bottom including the gap 7 is effectively achieved. be.

とならざるを得ないものである。 Incidentally, if the folded corner bottom part is formed according to the conventional method without making the cut 2, it will be as shown in Figs. As a result, as shown in FIG. 11, there is no non-laminated gap, and as a result, there is no choice but to create a heavy packaging bag with no air escape.
以上従つて、本考案によれば防湿と空気抜きと
云う相矛盾した技術的課題を克服した極めて実用
性に優れた重包装袋を提供し得るものである。 Therefore, according to the present invention, it is possible to provide a highly practical heavy-duty packaging bag that overcomes the contradictory technical problems of moisture proofing and air venting.
