(57) [Summary] [Problem] An object of the present invention is to make it easy to open without lowering the strength of the bag bottom when the bag bottom of a double bottomed paper bag without an opening is used as an opening. Supply paper bags. SOLUTION: The solution of the present invention is to make the width of a closing piece formed by bending the ends of the front and back surfaces of a paper bag into a width that does not allow both to overlap, and to make decorative paper on the upper side of the closing piece and reinforcing paper on the lower side. The lower side of the bag is prevented from deteriorating in strength by connecting and bonding both sides and both closing pieces, and the opening tape adhered to the lower reinforcing paper is reinforced without being hindered by both closing pieces. Following the paper, the upper decorative paper is also easily torn, allowing the contents to be discharged completely quickly.
Description
【０００１】[0001]
本考案は、ひだなし両底ばり紙袋の開封作業を容易にするため、袋底に必要な 構造を持たせることに関するものである。 The present invention relates to providing a necessary structure at the bottom of the bag in order to facilitate the opening operation of the unfolded double-bottomed paper bag.
【０００２】[0002]
本考案の課題は、次のとおりである。 ひだなし両底ばり紙袋において、袋底に開封機能をもたせようとする場合に、 通常の袋底形成方法すなわち袋の表面と裏面から折り曲げられて形成される閉鎖 片を重合させ、その上にアウトパッチを置く方法を採るときには、袋底に必要な 強度を保持するため、アウトパッチに複雑な加工（例えばポリエチレン製のクロ スヤーン又はワリフ等を貼り合わせる等）を施して強度を増すことが必要であり 、使用する糊には粘着力が強い反面、剥離しようとするときはそれが容易である 特性を持つものが望まれている。このような材料を使用して製造される紙袋は、 コストが高くならざるを得ず一般的に取り扱いにくいとされている。開封を容易 にするため、アウトパッチの引き裂き部分にあらかじめ切目線、ミシン目等を入 れておく方法も考案されているが、これはアウトパッチの強度にはマイナス要因 と考えられる。また、袋底形成前にその内側に別の紙を取り付け、その紙に開封 可能な部分を設けたものも考案されているが、これも「まずアウトパッチを剥が して両閉鎖片を開く」作業が必要であり、二重手間の感が拭えない。このような 事情から、簡単に開封が可能で、強度面にも問題のない新たな形態の両底ばり紙 袋の出現が期待されている。 The problems of the present invention are as follows. In the case of unfolded double-bottomed paper bags, when the bottom of the bag is to be provided with an opening function, the usual method of forming the bottom of the bag, that is, the closing piece formed by folding from the front and back surfaces of the bag is polymerized, and the top is put out In order to maintain the required strength at the bottom of the bag, it is necessary to increase the strength of the out patch by performing complex processing (for example, pasting a polyethylene cross yarn or warif, etc.). There is a demand for a glue to be used which has a strong adhesive force, but has a property that it can be easily peeled off. Paper bags manufactured using such materials are said to be expensive and generally difficult to handle. To facilitate opening, a method has been devised in which a cut line or perforation is made in advance at the tearing portion of the outpatch, but this is considered to be a negative factor in the strength of the outpatch. In addition, another paper has been devised in which another paper is attached to the inside of the bag before forming the bag bottom, and the paper is provided with an openable part. Work is required, and the feeling of double labor cannot be wiped out. Under such circumstances, the emergence of a new form of double-bottomed paper bag that can be easily opened and has no problem in strength is expected.

本考案によるひだなし両底ばり紙袋の袋底は、直線切りした筒状袋体の底部両 側面を内側に折り曲げて三角形部分を形成した後、長手方向に開封テープを付け たインナーパッチを、開封テープの接着面を下にして左右の三角形部分を連結す るように置き、その上に紙袋の表裏両面から同じ寸法で重合しない幅の閉鎖片を 折り曲げて置き、さらにその上にアウトパッチを置いて袋底を形成するもので、 開封テープが両閉鎖片の境目に位置しているものである。 The bottom of the fold-free double-sided paper bag according to the present invention is formed by bending both sides of the bottom of a straight-cut tubular bag inward to form a triangular portion, and then opening the inner patch with an opening tape in the longitudinal direction. Place the left and right triangles together so that the adhesive side of the tape is facing down.Fold the closure pieces of the same size and non-overlapping width on both sides of the paper bag, and place the outpatch on top. The opening tape is located at the border between the closing pieces.

直線切りにより形成した筒状袋本体１の底部両側面を内側に折り曲げて左右の 三角形部分２を形成した後、あらかじめ開封テープ３が、中心の位置で長手方向 に接着されている袋底幅とほぼ同じ幅のインナーパッチ４を、開封テープ接着面 を下にして左右の三角形部分２にそれぞれ重合させ、重合した部分のうちのイン ナーパッチ糊付け部５に糊付けして接着する。次に袋表裏面の端部をそれぞれ折 り曲げて閉鎖片６を形成し、それぞれその全面をインナーパッチ４に糊付け接着 する。インナーパッチ糊付け部５は、閉鎖片６によっても隠れないインナーパッ チ４の部分の下側に当たる三角形状の部分である。また、二個の閉鎖片６の幅は 同じ幅で、折り曲げた際に両者は重合せず、開封テープ３が持ち上げられる際に 妨げとならない位置でインナーパッチ４に接着する。最後に底幅より僅かに狭い 幅のアウトパッチ７を閉鎖片６の上に置き、全面を糊付け接着する。さらに、開 封テープ３の端部を持ち上げ易いように、インナーパッチ４の端部に１１センチ 程度の切れ目８を開封テープ３を挟む位置に入れておくか、または、この部分の インナーパッチ４を開封テープ３とともに突出させ凸状部９を形成しておくとよ い。凸状部９を形成した場合それによってインナーパッチ４の他端部に凹状部が 形成される場合がある（図示していない）が、その面積は僅かであり、アウトパ ッチ７が上から糊付け接着されているので袋底の強度には影響しない。 インナーパッチ４およびアウトパッチ７は、２層紙袋の場合は筒状袋本体１と 同じ紙質、坪量のものでよいが、３層紙袋の場合はそれに応じた耐久性を保持す るため、それぞれその紙質、坪量を向上させる必要がある。 After bending both sides of the bottom of the tubular bag body 1 formed by straight cutting into inward to form the left and right triangular portions 2, the opening width of the bag 3 in which the opening tape 3 is bonded in the longitudinal direction at the center position is determined in advance. The inner patches 4 having substantially the same width are superposed on the left and right triangular portions 2 with the opening tape bonding surface facing down, and the inner patch 4 is glued to the inner patch pasting portion 5 of the superposed portions. Next, the end portions of the front and back surfaces of the bag are bent, respectively, to form closure pieces 6, and the entire surfaces thereof are glued and adhered to the inner patch 4. The inner patch gluing portion 5 is a triangular portion that is below the portion of the inner patch 4 that is not hidden by the closing piece 6. The two closing pieces 6 have the same width, do not overlap when folded, and adhere to the inner patch 4 at a position where they do not hinder the lifting of the opening tape 3. Finally, an out patch 7 having a width slightly smaller than the bottom width is placed on the closing piece 6, and the entire surface is glued and adhered. Further, a cut 8 of about 11 cm is made at the end of the inner patch 4 at a position sandwiching the opening tape 3 so that the end of the opening tape 3 can be easily lifted. It is preferable that the convex portion 9 is formed so as to project together with the opening tape 3. When the convex portion 9 is formed, a concave portion may be formed at the other end of the inner patch 4 (not shown), but the area is small, and the out patch 7 is glued from above. Since it is adhered, it does not affect the strength of the bag bottom. The inner patch 4 and the outer patch 7 may be of the same paper quality and basis weight as the cylindrical bag body 1 in the case of a two-layer paper bag, but in the case of a three-layer paper bag, each has a corresponding durability. It is necessary to improve the paper quality and basis weight.

本考案による紙袋の袋底は、閉鎖片が底幅の１／２以下で重合していないが、 インナーパッチとアウトパッチで上下から連結接着されているので、一般的な製 造形態すなわち閉鎖片を重合させその上からアウトパッチを接着する場合に比べ て、耐久性は勝るとも劣らないうえに、閉鎖片が重合していないので、開封テー プを引き上げながら横方向に引っ張ると、閉鎖片に妨げられることなくインナー パッチとアウトパッチをいずれも横方向に引き裂くことができる。その際引き裂 かれた部分に手先きを入れて上下に開くようにすると、内容物が排出されようと する力が加わって、インナーパッチは両端の糊付けされた三角形の部分を残して 容易に上下方向に開かれ、それにともなって両閉鎖片及びアウトパッチも開かれ て排出が完全迅速に行われる。 In the bag bottom of the paper bag according to the present invention, the closing piece is not polymerized in less than half the width of the bottom, but since the inner patch and the out patch are connected and bonded from above and below, a general manufacturing form, that is, a closing piece. As compared to the case where the outpatch is adhered from above, the durability is not less than superior, and the closure piece is not polymerized. Both inner and out patches can be torn laterally without interruption. At this time, if the torn part is put up with a fingertip and opened up and down, a force is applied to discharge the contents, and the inner patch is easily moved up and down leaving the triangular parts glued at both ends. Opening in the direction, with which both closure pieces and outpatches are also opened, the drainage takes place completely quickly.
