Therefore, when the inner patch 11 is bonded to the development surface 8, the surface 20 a of the folded piece 20 that does not have the opening tape 10 is attached to the triangular folding portion 5 of the development surface 8. Therefore, the contents are not leaked, and the inner patch 11 is easily torn by the opening piece 21.
一方、前記アウターパッチ１２は、展開面８を構成する上紙２ａ及び下紙２ｂが折れ筋９ａ、９ｂに沿って折り畳まれ、上紙２ａと下紙２ｂとが重ならない状態となり、その上に貼り付けられ、開封容易な袋１の底部を全体的且つ最終的に保護しているものである。すなわち、アウターパッチ１２は、その一方の端部がインナーパッチ１１の一方の端部上を覆い、その他方の端部がインナーパッチ１１の他方の端部よりも外方に延出した状態で覆っている。これにより、内容物がインナーパッチ１１の他方の端部から開封テープ１０を伝わって、外部に漏れるのを防ぐことができる。 On the other hand, in the outer patch 12, the upper paper 2a and the lower paper 2b constituting the development surface 8 are folded along the folding lines 9a and 9b so that the upper paper 2a and the lower paper 2b do not overlap with each other. The bottom of the bag 1 that is affixed and easily opened is totally and finally protected. That is, the outer patch 12 is covered with one end portion covering one end portion of the inner patch 11 and the other end portion extending outward from the other end portion of the inner patch 11. ing. As a result, the contents can be prevented from leaking outside through the opening tape 10 from the other end of the inner patch 11.
そして、アウターパッチ１２は、その一方の端部にインナーパッチ１１の切り込み１３に沿ったスリット１４、１４が設けられ、スリット１４、１４間に切裂片２２が形成されて、その上、開封テープ１０に沿ってインナーパッチ１１に線状に貼り付けられている。これにより、アウターパッチ１２の切裂機構は、インナーパッチ１１における切裂機構と一体となって、切裂片２２ともども開封片２１により、インナーパッチ１１及びアウターパッチ１２を一気に容易且つ完全に切り裂くことができ、開封容易な袋１の底部を一気に開封することになる。なお、スリット１４は後に詳述するように１つでもよい。 The outer patch 12 is provided with slits 14, 14 along the notch 13 of the inner patch 11 at one end thereof, a slit 22 is formed between the slits 14, 14, and the opening tape 10. Is affixed linearly to the inner patch 11. Thereby, the tearing mechanism of the outer patch 12 is integrated with the tearing mechanism in the inner patch 11, and the inner patch 11 and the outer patch 12 can be easily and completely cut at once by the tear piece 22 by the opening piece 21. The bottom of the bag 1 that can be opened easily is opened at once. One slit 14 may be provided as will be described in detail later.
上記構成になる開封容易な袋１は、以下のようにして作られる。
まず、２層以上の紙状筒２について、その径及び長さとも使用目的に合わせた任意のものを選択する。そして、図２に示すように、選択した紙状筒２を折り潰し、その折り潰した紙状筒２の一方の開口端３Ａ側に、この開口端３Ａと平行な折り目４を所定幅で付け、この紙状筒２の開口端３Ａの両角Ｃ１、Ｃ１を二点鎖線で示すように、折り目４まで折り込む。同じく、この紙状筒２の他方の開口端側にも、この開口端と平行な折り目を所定幅で付け、他方の開口端の両角も、折り目まで折り込む。
The easy-open bag 1 having the above-described configuration is produced as follows.
First, for the two or more paper-like cylinders 2, the diameter and length are arbitrarily selected according to the purpose of use. Then, as shown in FIG. 2, the selected paper tube 2 is folded, and a crease 4 parallel to the opening end 3A is attached to the opening end 3A side of the folded paper tube 2 with a predetermined width. The two corners C1 and C1 of the opening end 3A of the paper tube 2 are folded up to the crease 4 as indicated by a two-dot chain line. Similarly, on the other opening end side of the paper tube 2, a crease parallel to the opening end is provided with a predetermined width, and both corners of the other opening end are folded up to the fold.
次に、紙状筒２の両角Ｃ１、Ｃ１を図２の二点鎖線で示す折り目４まで折り込んだ状態で、紙状筒２の折り潰しにより形成した上紙２ａ及び下紙２ｂのうち、上紙２ａを折り目４に沿って開き、図３に示すように、両側及びその中心部に三角折込み部５、６及び開口部７を有する展開面８を形成する。さらに、展開面８の上紙２ａ及び下紙２ｂを開口部７側に折り畳んでも、開口部７を塞ぐことがない折れ筋９ａ、９ｂを上紙２ａ及び下紙２ｂに付ける。すなわち、開口部７を塞ぐことがない折れ筋９ａ、９ｂを上紙２ａ及び下紙２ｂに付けるには、上紙２ａ及び下紙２ｂを折り畳んだ際、それぞれの開口端３Ａが重ならないようにすればよい。 Next, in the state where both corners C1 and C1 of the paper tube 2 are folded up to the crease 4 shown by the two-dot chain line in FIG. The paper 2a is opened along the crease 4, and as shown in FIG. 3, a development surface 8 having triangular folding portions 5 and 6 and an opening 7 on both sides and the center thereof is formed. Further, even if the upper paper 2a and the lower paper 2b of the development surface 8 are folded toward the opening 7, the folding lines 9a and 9b that do not block the opening 7 are attached to the upper paper 2a and the lower paper 2b. That is, in order to attach the creases 9a and 9b that do not block the opening 7 to the upper paper 2a and the lower paper 2b, when the upper paper 2a and the lower paper 2b are folded, the respective opening edges 3A do not overlap. do it.
例えば、図１に示すように、開封容易な袋１の底部幅：Ｗ０とすると、上紙２ａ及び下紙２ｂが担当する底部幅：Ｗ１は半分となり、Ｗ０＝Ｗ１×２となる。また、上紙２ａの開口端３Ａと下紙２ｂの開口端３Ａとの長さ：Ｗ２とすると、上紙２ａ及び下紙２ｂが担当する長さ：Ｗ３は半分となり、Ｗ２＝Ｗ３×２となる。よって、上紙２ａ及び下紙２ｂ開口端３Ａから折れ筋９ａ、９ｂまでの長さ：Ｗ４とすると、Ｗ４＝Ｗ１−Ｗ３＝１／２（Ｗ０−Ｗ２）となり、折れ筋９ａは、開口端３ＡからＷ４離れた上紙２ａ上に開口端３Ａと平行に付けることになって、折れ筋９ｂも、開口端３ＡからＷ４離れた下紙２ｂ上に開口端３Ａと平行に付けることになる。 For example, as shown in FIG. 1, if the bottom width of the bag 1 that is easy to open is W0, the bottom width W1 that the upper paper 2a and the lower paper 2b are responsible for is halved, and W0 = W1 × 2. If the length of the opening end 3A of the upper paper 2a and the opening end 3A of the lower paper 2b is W2, the length W3 in charge of the upper paper 2a and the lower paper 2b is halved, and W2 = W3 × 2. Become. Therefore, if the length from the opening end 3A of the upper paper 2a and the lower paper 2b to the folding lines 9a, 9b: W4, W4 = W1-W3 = 1/2 (W0-W2), and the bending line 9a has an opening end. The folding line 9b is also attached on the lower paper 2b away from the opening end 3A in parallel with the opening end 3A.
そして、インナーパッチ１１を上紙２ａ及び下紙２ｂ上の図３の二点鎖線で示す位置に貼り付け、開口部７を完全に塞ぐ。 And the inner patch 11 is affixed on the upper paper 2a and the lower paper 2b in the position shown with the dashed-two dotted line of FIG. 3, and the opening part 7 is completely plugged up.
その後、図７に示すように、上紙２ａを折れ筋９ａに沿い開口部７側に折り畳み、インナーパッチ１１及び三角折込み部５上に貼り付け、さらに、下紙２ｂも同じく折れ筋９ｂに沿い開口部７側に折り畳み、インナーパッチ１１及び三角折込み部６上に貼り付ける（図８参照）。さらに、その上に、アウターパッチ１２を貼り付けるが（図９参照）、その際重要なことは、アウターパッチ１２の切裂片２２をインナーパッチ１１の開封片２１に沿わせ、且つ、開封テープ１０に沿ってインナーパッチ１１にアウターパッチ１２を少なくとも線状に貼り付けることである。このようにすることで、図１０に示すように、開封容易な袋１内に内容物が充填された状態で、アウターパッチ１２の切裂機構は、インナーパッチ１１における切裂機構と一体となって、開封片２１及び切裂片２２により、インナーパッチ１１及びアウターパッチ１２を一気に切り裂き、開封出来るようになる。 After that, as shown in FIG. 7, the upper paper 2a is folded along the folding line 9a to the opening 7 side and attached on the inner patch 11 and the triangular folding part 5, and the lower paper 2b is also along the folding line 9b. It folds to the opening 7 side and affixes on the inner patch 11 and the triangular folding part 6 (refer FIG. 8). Further, an outer patch 12 is affixed thereon (see FIG. 9). In this case, what is important is that the cut piece 22 of the outer patch 12 is placed along the opening piece 21 of the inner patch 11 and the opening tape 10 The outer patch 12 is affixed to the inner patch 11 along at least a linear shape. By doing so, as shown in FIG. 10, the tearing mechanism of the outer patch 12 is integrated with the tearing mechanism of the inner patch 11 in a state where the contents are filled in the bag 1 that is easy to open. Thus, the inner patch 11 and the outer patch 12 can be cut and opened at once by the opening piece 21 and the cut piece 22.
なお、紙状筒２の他方の開口端でも、紙状筒２の折り潰しにより生じた上紙及び下紙のうち、上紙を折り目に沿い開いて、両側及びその中心部に三角折込み部及び開口部を有する展開面を形成し、さらに、上紙及び下紙に折り目に平行な２本の折れ筋を付け、上紙を折れ筋に沿って折り畳んで開口部を塞いで貼り合わせ、その上に下紙も折れ筋に沿って折り畳んで貼り合わせ、開口部を塞ぐ。なお、インナーパッチや内容物投入口並びに化粧紙が必要で有れば装備する。 It should be noted that, even at the other opening end of the paper tube 2, among the upper paper and the lower paper generated by the folding of the paper tube 2, the upper paper is opened along the fold line, and the triangular folding portion and A development surface having an opening is formed, and two folding lines parallel to the crease are attached to the upper sheet and the lower sheet, the upper sheet is folded along the folding line, and the opening is closed and bonded. The lower paper is also folded along the crease and pasted together to close the opening. If an inner patch, contents inlet, and decorative paper are necessary, they are equipped.
上記構成になる開封容易な袋１は次のように使用される。
まず、開封容易な袋１内に紙状筒２の他方の開口端から、例えば、内容物投入口が有ればそれに粉粒体などの供給源を接続して、エアーと共に粉粒体を開封容易な袋１内に送り粉粒体を充填する。充填が終了したら内容物投入口を封止しその他の必要作業を終了すれば、粉粒体充填済みの開封容易な袋１となり、流通に乗せることができる。
The easily opened bag 1 having the above-described configuration is used as follows.
First, from the other open end of the paper tube 2 in the bag 1 that is easy to open, for example, if there is a content inlet, a supply source such as powder is connected to it and the powder is opened together with air An easy bag 1 is filled with feed powder particles. When the filling is completed, the content inlet is sealed and other necessary operations are completed, so that the bag 1 can be easily opened and filled with the powder and can be put into circulation.
そして、開封容易な袋１内に充填されている粉粒体を使用したい場合には、図１２及び１３に示すように、開封片２１及び切裂片２２を手指でつかんで引き裂けば、インナーパッチ１１及びアウターパッチ１２を一気に切り裂くことが出来、開封容易な袋１を開封出来て、粉粒体を取り出し使用することが出来る。 When it is desired to use a granular material filled in the bag 1 that can be easily opened, as shown in FIGS. 12 and 13, the inner patch 11 can be obtained by grasping and tearing the opening piece 21 and the cut piece 22 with fingers. And the outer patch 12 can be cut at a stretch, the bag 1 that is easy to open can be opened, and the granular material can be taken out and used.
図１１は、アウターパッチ１２の一方の端部にスリット１４、１４が無く、したがって切裂片２２が形成されておらず、その代わりに１本のスリット１４Ａが設けられている開封容易な袋１を示したものである。そして、このスリット１４Ａから、開封テープ１０に沿ってインナーパッチ１１にアウターパッチ１２が線状に貼り付けられている。その他の構成、作用は図１ないし図１０に示す開封容易な袋１と同様である。 FIG. 11 shows an easily opened bag 1 in which one end portion of the outer patch 12 is not provided with slits 14 and 14 and therefore no cut piece 22 is formed, and instead one slit 14A is provided. It is shown. The outer patch 12 is linearly attached to the inner patch 11 along the opening tape 10 from the slit 14A. Other configurations and operations are the same as those of the easy-open bag 1 shown in FIGS.
