【考案の属する技術分野】本考案は、セメントやメリケン粉等の粉体を収容 する紙袋に係り、特に不還弁を付設した粉体包装用弁付き紙袋に関するものであ る。TECHNICAL FIELD The present invention relates to a paper bag containing powder such as cement and Meriken powder, and more particularly to a paper bag with a valve for powder packaging provided with a non-return valve.
【0002】[0002]
【従来技術】従来この種の紙袋は図7(a)に示すように、ガゼット折りの ひだ10を左右に施した袋体11は吹込口を形成する部分Bを残して切り落とし 、吹込口形成部分Bを同図(b)のように内側に折り込んで吹込口を形成してい る。図中Hは不還弁の突出部の高さで切り落とし部分12の寸法を示す、Lは袋 となつたときの寸法、L1 は筒状の切断寸法を示す(L=L1 −H)、Bは弁の 折り込み基準寸法、Dは吹込口の折径、13は上口ミシン縫いのミシン目線であ る。 以上のように従来の紙袋は切り落とし部分12があるため、それだけ資材を無 駄にしていたことになり、その量は莫大の量に達している。2. Description of the Related Art Conventionally, as shown in FIG. 7 (a), a paper bag of this type has a bag body 11 having gusset-folded folds 10 on the left and right, which is cut off except for a portion B forming a blow-in port. B is folded inward as shown in FIG. 3 (b) to form a blow port. In the figure, H is the height of the protrusion of the non-return valve and shows the size of the cut-off portion 12. L is the size when the bag is connected to the bag, L1 is the cylindrical cutting size (L = L1-H), B Is the standard folding dimension of the valve, D is the diameter of the blow-in opening, and 13 is the perforation line of the upper sewing machine. As described above, since the conventional paper bag has the cut-off portion 12, it means that the material is wasted by that much, and the amount thereof reaches an enormous amount.

【課題を解決するための手段】本考案の手段は、左右をガゼット折りした袋 体の真直口縁の一隅部表裏両面に方形の弁形成用小紙片を当て、小紙片は対角線 折目を施して3角形先方片と3角形後方片に分け、3角形先方片のみの裏面に接 着剤を塗布して袋体に接着し、接着した3角形先方片と共に袋体の上部をガゼッ ト折りの内側に折り込み、かつ3角形後方片を真直口縁に沿って残存させ、しか る後真直口縁を、残存した3角形後方片と一緒に封止テープを当ててミシン縫い し、折り込んだ3角形先方片及び3角形後方片により吹込口を形成したことを特 徴とする粉体包装用弁付き紙袋。[Means for Solving the Problems] According to the means of the present invention, a square valve forming small piece of paper is applied to both the front and back sides of one corner of a straight mouth edge of a bag body with left and right gusset folds, and the small piece of paper is diagonally folded. Into a triangular front piece and a triangular rear piece, apply adhesive to the back surface of the triangular front piece only, and adhere it to the bag body, and fold the upper part of the bag body together with the adhered triangular front piece with a gusset fold. Folded inward and left the triangular rear piece along the straight edge, then sew the straight edge together with the remaining triangular rear piece with a sealing tape and sew it with a sewing machine A paper bag with a valve for powder packaging, characterized in that a blowing port is formed by a front piece and a triangular rear piece.

【考案の実施の形態】図1乃至図6は本考案に係る粉体包装用弁付き紙袋の 具体例を示す。図1において2は左右をガゼット折り1、1した袋体で真直口縁 2aの一隅部には表裏両面に弁形成小紙片3を当てる。この小紙片3は正方形で 対角線折目3aを施してこれを境に3角形先方片3bと3角形後方片3cに分け る。そして3角形先方片3bのもの裏面に接着剤7を塗布して袋体2に接着する (図2参照)。次に接着した3角形先方片3bは対角線折目3aより内側に折り 込む。その際袋体2のガゼット折り1、1部分も図3に示すP1,P2 から内側に 折り込む、かくして接着しない3角形後方片3cは真直口縁2aに沿って残され る(図4参照)。その状態で図5に示すように封止テープ4を真直口縁2aに2 つ折りして被せ、ミシン縫い5して吹込口6を形成する。1 to 6 show a specific example of a paper bag with a valve for powder packaging according to the present invention. In FIG. 1, reference numeral 2 denotes a bag body having left and right folded gussets 1 and 1, and a valve-forming small paper piece 3 is applied to both front and back surfaces at one corner of a straight edge 2a. This small piece of paper 3 is square and has a diagonal fold 3a, which is divided into a triangular front piece 3b and a triangular rear piece 3c. Then, the adhesive 7 is applied to the back surface of the triangular tip piece 3b and adhered to the bag body 2 (see FIG. 2). Next, the bonded triangular front piece 3b is folded inward from the diagonal fold 3a. At this time, the gusset folds 1 and 1 of the bag body 2 are also folded inward from P1 and P2 shown in FIG. 3, and thus the triangular rear piece 3c which is not adhered is left along the straight edge 2a (see FIG. 4). In this state, as shown in FIG. 5, the sealing tape 4 is folded in two on the straight edge 2a and sewn on the sewing machine 5 to form the blowing port 6.

【考案の効果】本考案は以上説明したように、従来の吹込口を形成するため の切り落し部分を施す必要がなく、小紙片3を袋体2の表裏両面に接着すること で完全な吹込口ができるため、無駄なく成形でき経済的利点は非常に大きい。As described above, according to the present invention, it is not necessary to provide a cut-off portion for forming a conventional blowing port, and the small paper piece 3 is adhered to both front and back surfaces of the bag body 2 to complete the blowing port. Therefore, it is possible to mold without waste and the economic advantage is very large.
