【発明の属する技術分野】
オーバーテープが袋本体の両側に突出しない紙袋。
【０００２】
【従来技術】
従来の重包装袋体においては、そのオーバーテープが袋本体の両側に突出していた。なぜならば、袋本体の筒状体先端部は折り込み部を設けて折り込んでおり、もし、オーバーテープを袋本体の筒状体の幅方向に収めようとすると、オーバーテープに装着するカットテープのつまみ部は設けた切り込みが、折り込み部の開口部に連通して、この連通した開口部から異物の侵入することがあるからである。
【０００３】
【解決しようとする課題】
オーバーテープの両側部が、袋本体の両側に突出しないで、搬送に便利な形態の重包装袋を得ること。ただし、折り込み部の開口部から異物が侵入してはならない。
【０００４】
【第１発明の技術的手段】
筒状体先端を折り込み線１ａｘで折り込んで、折り込み部１ａを設けた袋本体１に、糊着層あるいは熱接着樹脂層２ｘを裏面全面に設けたオーバーテープ２を冠せ、

第１発明は、図１〜１０に示されるように
両側にひだｇを有するまたは有しない筒状体先端を折り込み線１ａｘで折り込んで、折り込み部１ａを設けた袋本体１に、糊着層あるいは熱接着樹脂層２ｘを裏面全面に設けたオーバーテープ２を冠せ、
オーバーテープ２に装着したカットテープ３を引きちぎることにより開封する紙袋において、
【００１２】
袋本体１の折り込み部１ａの筒状先端の開口部に第１段部１ａ１、第２段部１ａ２、第３段部１ａ３を設ける。
【００１３】
そして、図１，図２（ａ），図３のように袋本体１には、カットテープ３のレベルを、第２段部１ａ２の開口部のレベルに一致せしめるとともに、第３段部１ａ３の開口部先端はカットテープ３のレベルと、わづかに異なるレベルとしておき、さらに、第１段部１ａ１と第２段部１ａ２の境い目相当位置の折り込み部１ａには切れ目１ｍを設けておく。
【００１４】
一方、図１，図２（ｂ），図４のように、オーバーテープ２のカットテープ３は前記第１段部１ａ１の開口部と同一のレベルに設けてある、かつ前記第１段部１ａ１、第２段部１ａ２の境い目相当位置のオーバーテープ２にはミシン目２ｍを設けておく。
【００１５】
以下、その作動順序を説明する。
第１に、第３段部１ａ３の開口部を封緘する部分のオーバーテープ糊着層あるいは熱接着樹脂層２ｘの部分２ｘ１を剥がす。部分２ｘ１は切込み４の一方のものの位置に相当する。
【００１６】
第２に、カットテープ３でオーバーテープ２を引きちぎることにより、前記第２段部１ａ２，第３段部１ａ３の開口部を開封すると同時に、折り込み線１ａｘを境として反転せしめ、第１段部１ａ１はオーバーテープ２とともに反転しない。

【第２発明の実施の形態】
図１０〜１５において、

【００１９】
第２発明は、オーバーテープ１２の両側部を袋本体１１の両側に突出させないため、袋本体１１の折り込み部１１ａに、中央凸部１１ａ１、両側凹部１１ａ２，１１ａ２を設ける。
またオーバーテープ１２には、前記中央凸部１１ａ１と両側凹部１１ａ２，１１ａ２との境い目相当位置のオーバーテープ１２にミシン目１２ｍを設ける。（図１０，１２（ｂ），１３，１４）
【００２０】
また折り込み部１１ａの中央凸部１１ａ１と両側凹部１１ａ２，１１ａ２の境い目相当位置の折り込み部１１ａには切目１１ｍを設ける。（図１０，１２（ａ），１４）
【００２１】
以下、その作用について説明する。
カットテープ１３で、オーバーテープ１２を引きちぎると、カットテープ１３のレベルを中央凸部１１ａ１の開口部と同じレベルにしておくので、中央凸部１１ａ１の開口部は開口し、かつ、切目１１ｍを境いとして、両側凹部１１ａ２，１１ａ２を残して反転する。（図１４）
【００２２】
このとき、オーバーテープ１２もミシン目１２ｍを境としてまた、図１５に示すように、中央凸部１１ａ１とともに反転する。
これに対し、図１４に示すように両側凹部１１ａ２，１１ａ２は反転することがない。なぜならば、糊着層１２ｘによって、両側凹部１１ａ２，１１ａ２の開口部は閉塞されたままで、反転することができないからである。
【００２３】
また図１５のようにオーバーテープ１２の両側部もミシン目１２ｍを境として反転しない。両側凹部１１ａ２，１１ａ２を糊着層あるいは熱接着樹脂層１２ｘで糊着しているので、反転することがない。
結局、折り込み部１１ａの中央凸部１１ａ１部分のみが、オーバーテープ１２の中央部分とともに反転する。この状態を図１４に示してある。
【００２４】
したがって、両側凹部１１ａ２，１１ａ２の開口部は閉塞されている間に、中央凸部１１ａ１のみから内容物は排出されるので、両側凹部１１ａ２，１１ａ２の開口部から異物の侵入することはない。
【００２５】
【第３発明の実施の形態】
図１６〜図２０において、
１１１：袋本体、１１１ａ：折り込み部、１１１ａ１：中央凹部、１１１ａ２：両側凸部、１１１ｍ：切目、
１１２：オーバーテープ、１１２ｘ：糊着層あるいは熱接着樹脂層、１１２ｍ：ミシン目、
１１３：カットテープ、
１１４：切り込み、
ｇ：ひだ、
【００２６】
第３発明は、オーバーテープ１１２の両側部を袋本体１１１の両側に突出させないため、次の構成をとったものである。
袋本体１１１の折り込み部１１１ａの開口部に中央凹部１１１ａ１、両側凸部１１１ａ２を設ける。（図１６，図１７（ａ），図１９）
【００２７】
そして、中央凹部１１１ａ１と両側凸部１１１ａ２，１１１ａ２との境い目相当位置の折り込み部１１１ａに切目１１１ｍを切り込んでおく。
【００２８】
一方、オーバーテープ１１２の前記中央凹部１１１ａ１と両側凸部１１１ａ２，１１１ａ２との境い目相当箇所のオーバーテープ１１２にミシン目１１２ｍを刻み込んでおく。（図１６，図１７（ｂ），図１９）
【００２９】
また、オーバーテープ１１２に装着したカットテープ１１３のレベルには中央凹部１１１ａ１の開口部のレベルと一致させておく。（図１７）
【００３０】
以下その作用について説明する。
カットテープ１１３で、オーバーテープ１１２を引きちぎると、折り込み部１１１ａの開口部のみ開口して、ミシン目１１１２ｍで分離されたオーバーテープ１１２の部分とともに反転する。（図１８，図１９）
【００３１】
一方、両側凸部１１１ａ２，１１１ａ２は図１８，１９，２０に示すように、その開口部は、オーバーテープ１１２の残存部１１２Ｒの糊着層あるいは熱接着樹脂層１１２ｘにより糊着され、開封されることがない。
【００３２】
したがって、内容物は中央凹部１１１ａ１部分のみから排出されるとともに、両側凸部１１ａ２，１１ａ２の開口部は封緘されて、異物の侵入することがない。
【００３３】
【第１発明の効果】
折り込み部１ａの反転時、第１，第２段部１ａ２，１ａ３のみ反転して内容物を排出する。そして、第１段部１ａ１はオーバーテープ２とともに反転しないので、反転しない第１段部１ａ１の開口部から異物の侵入することがない。
【００３４】
かくして、オーバーテープ２が袋本体１の両側より突出することなく、搬送に適合した形態の紙袋を得ることができる。
【００３５】
【第２発明の効果】
第１発明と異なり中央凸部１１ａ１のみ開封時反転して、内容物を排出する。その両側凹部１１ａ２，１１ａ２は開口することなく異物の侵入することがない。そして第１発明と同様、搬送に適合した形状の紙袋を得ることができる。
【００３６】
【第３発明の効果】
第２発明と異なり、中央凹部１１１ａ１のみ開封時反転して内容物を排出する。その両側凸部１１１ａ２，１１１ａ２は開口することなく、異物の侵入することがない。そして第１，第２発明と同様、搬送に適合した形状の紙袋を得ることができる。

[0011]
As shown in FIGS. 1 to 10, the first invention folds the end of a cylindrical body with or without pleats g on both sides along a fold line 1 ax, and attaches a glue layer or Put over tape 2 with thermal adhesive resin layer 2x on the entire back surface,
In a paper bag opened by tearing the cut tape 3 attached to the over tape 2,
[0012]
A first step portion 1 a 1, a second step portion 1 a 2, and a third step portion 1 a 3 are provided in the opening at the cylindrical tip of the folding portion 1 a of the bag body 1.
[0013]
As shown in FIGS. 1, 2A, and 3, the bag body 1 has the cut tape 3 at the same level as the opening of the second step portion 1a2, and the third step portion 1a3. The front end of the opening is set to a level that is slightly different from the level of the cut tape 3, and a cut 1m is provided in the folding portion 1a at a position corresponding to the boundary between the first step portion 1a1 and the second step portion 1a2.
[0014]
On the other hand, as shown in FIGS. 1, 2B, and 4, the cut tape 3 of the over tape 2 is provided at the same level as the opening of the first step portion 1a1, and the first step portion 1a1. A perforation 2m is provided in the over tape 2 at a position corresponding to the boundary of the second step portion 1a2.
[0015]
The operation sequence will be described below.
First, the portion 2x1 of the over-tape adhesive layer or the thermal adhesive resin layer 2x that seals the opening of the third step portion 1a3 is peeled off. The portion 2x1 corresponds to the position of one of the cuts 4.
[0016]
Second, by tearing the over tape 2 with the cut tape 3, the openings of the second step portion 1a2 and the third step portion 1a3 are opened, and at the same time, the first step portion 1a1 is reversed with the folding line 1ax as a boundary. Does not reverse with overtape 2.

FIG. 6 is an exploded perspective view of the over tape 2 when opened, and FIG. 7 is a perspective view showing the state when the over tape 2 is opened.
[0018]
[Second Embodiment]
10-15,
11: Bag main body, 11a: Folded part, 11a1: Center convex part, 11a2: Both side recessed part, 11m: Cut,
12: Over tape, 12x: Adhesive layer or thermal adhesive resin layer, 12m: Perforation,
13: Cut tape,
14: Cut,
g: folds,
[0019]
According to the second aspect of the invention, the central projecting portion 11a1 and the both side recessed portions 11a2 and 11a2 are provided in the folded portion 11a of the bag body 11 so that the both side portions of the over tape 12 do not protrude on both sides of the bag body 11.
In the over tape 12, a perforation 12m is provided in the over tape 12 at a position corresponding to the boundary between the central convex portion 11a1 and the concave portions 11a2 and 11a2. (FIGS. 10, 12 (b), 13, 14)
[0020]
In addition, a cut 11m is provided in the folding portion 11a at a position corresponding to the boundary between the central convex portion 11a1 of the folding portion 11a and the both side concave portions 11a2 and 11a2. (Fig. 10, 12 (a), 14)
[0021]
The operation will be described below.
When the over tape 12 is torn off with the cut tape 13, the level of the cut tape 13 is set to the same level as the opening of the central convex portion 11a1, so the opening of the central convex portion 11a1 is open and the boundary of the cut 11m. As a matter of course, the two sides of the recesses 11a2 and 11a2 are left and reversed. (Fig. 14)
[0022]
At this time, the over tape 12 is also reversed with the central convex portion 11a1 at the perforation 12m as shown in FIG.
On the other hand, as shown in FIG. 14, the concave portions 11a2 and 11a2 on both sides are not reversed. This is because the opening portions of both side recesses 11a2 and 11a2 remain closed by the adhesive layer 12x and cannot be reversed.
[0023]
Further, as shown in FIG. 15, both side portions of the over tape 12 are not reversed with the perforation 12m as a boundary. Since the concave portions 11a2 and 11a2 on both sides are glued with the glue layer or the heat bonding resin layer 12x, they do not reverse.
Eventually, only the central convex portion 11a1 portion of the folded portion 11a is reversed together with the central portion of the over tape 12. This state is shown in FIG.
[0024]
Accordingly, since the contents are discharged only from the central convex portion 11a1 while the openings of the both side concave portions 11a2 and 11a2 are closed, foreign matter does not enter from the openings of the both side concave portions 11a2 and 11a2.
[0025]
[Third Embodiment]
16 to 20,
111: Bag main body, 111a: Folded portion, 111a1: Central concave portion, 111a2: Both side convex portion, 111m: Cut,
112: Over tape, 112x: Adhesive layer or thermal adhesive resin layer, 112m: Perforation,
113: Cut tape,
114: Notch
g: folds,
[0026]
The third aspect of the invention adopts the following configuration in order not to project both side portions of the over tape 112 to both sides of the bag body 111.
A central concave portion 111a1 and both side convex portions 111a2 are provided in the opening of the folded portion 111a of the bag body 111. (Fig. 16, Fig. 17 (a), Fig. 19)
[0027]
Then, a cut 111m is cut into a folding portion 111a at a position corresponding to the boundary between the central concave portion 111a1 and the both side convex portions 111a2 and 111a2.
[0028]
On the other hand, a perforation 112m is cut into the over tape 112 at a portion corresponding to the boundary between the central concave portion 111a1 and the both side convex portions 111a2 and 111a2 of the over tape 112. (Fig. 16, Fig. 17 (b), Fig. 19)
[0029]
Further, the level of the cut tape 113 attached to the over tape 112 is made to coincide with the level of the opening of the central recess 111a1. (Fig. 17)
[0030]
The operation will be described below.
When the over tape 112 is torn with the cut tape 113, only the opening portion of the folding portion 111a is opened, and the over tape 112 is reversed together with the portion of the over tape 112 separated by the perforation 1112m. (FIGS. 18 and 19)
[0031]
On the other hand, as shown in FIGS. 18, 19, and 20, the opening portions of the both side convex portions 111 a 2 and 111 a 2 are glued by the glue layer or the thermal adhesive resin layer 112 x of the remaining portion 112 R of the over tape 112 and opened. There is nothing.
[0032]
Therefore, the contents are discharged only from the central concave portion 111a1, and the opening portions of the both side convex portions 11a2 and 11a2 are sealed so that no foreign matter enters.
[0033]
[Effect of the first invention]
When the folding portion 1a is reversed, only the first and second step portions 1a2 and 1a3 are reversed and the contents are discharged. And since the 1st step part 1a1 is not reversed with the over tape 2, a foreign material does not penetrate | invade from the opening part of the 1st step part 1a1 which is not reversed.
[0034]
Thus, a paper bag having a form suitable for conveyance can be obtained without the over tape 2 projecting from both sides of the bag body 1.
[0035]
[Effect of the second invention]
Unlike the first invention, only the central convex portion 11a1 is reversed when opened, and the contents are discharged. The recesses 11a2 and 11a2 on both sides do not open and foreign matter does not enter. As in the first invention, a paper bag having a shape suitable for conveyance can be obtained.
[0036]
[Effect of the third invention]
Unlike the second invention, only the central recess 111a1 is reversed when opened, and the contents are discharged. The convex portions 111a2 and 111a2 on both sides do not open and foreign matter does not enter. As in the first and second inventions, a paper bag having a shape suitable for conveyance can be obtained.
