Description
本発明は、封緘キャップ及び封緘容器に関する。 The present invention relates to a sealing cap and a sealing container.
この種の封緘キャップとして、容器体の口頸部外面への嵌着用の基筒部から上方へ延出する中間筒部の上周端を、有頂筒状の帽筒部の下周端に連設させるとともに、
前記中間筒部の後端部を、前記基筒部及び帽筒部を連結する薄肉のヒンジ部に、中間筒部の前半部を、分離線を介して前記基筒部及び帽筒部と連続する開封バンドにそれぞれ形成し、かつ開封バンドとヒンジ部との間の中間筒部分の上端を、弱化線を介して前記帽筒部の下端に連結させ、前記開封バンドの周方向の端部に付設した摘み部を操作することにより、開封バンドを除去した後に、帽筒部を開方向へ引っ張ると、前記弱化線が破断され、帽筒部を解放することが可能に形成したものが知られている（特許文献１）。
なお前記摘み部は、基筒部の筒軸から見て、ヒンジ部から９０度離れた方向（左右方向）に配置されている。このような構成とすると、封緘キャップを金型で成形する際に摘み部を金型のパーティングライン上に配置することにより、型抜きが容易となるからである。
As this kind of sealing cap, the upper peripheral end of the intermediate cylindrical portion that extends upward from the base cylindrical portion that is fitted to the outer surface of the mouth and neck of the container body is used as the lower peripheral end of the cap-shaped cylindrical tube portion. As well as connecting
The rear end portion of the intermediate tube portion is connected to the thin hinge portion connecting the base tube portion and the cap tube portion, and the first half portion of the intermediate tube portion is connected to the base tube portion and the cap tube portion via a separation line. Each of the opening band and the upper end of the intermediate cylinder part between the opening band and the hinge part is connected to the lower end of the cap cylinder part via a weakening line, and is connected to the circumferential end of the opening band. It is known that when the cap band is pulled in the opening direction after the opening band is removed by operating the attached knob, the weakening line is broken and the cap cylinder can be released. (Patent Document 1).
In addition, the said knob | pick part is arrange | positioned in the direction (left-right direction) away from the hinge part seeing from the cylinder axis of the base cylinder part. This is because, when the sealing cap is molded with a mold, the picking part is arranged on the parting line of the mold, so that the mold can be easily removed.
特許文献１のものは、開封バンドの周方向の端部に付設された摘み部を周方向一方へ引っ張ることで開封バンドを除去するように構成されているから、開封バンドを設けることができる箇所に設計上の制約がある。例えば前述のように基筒部の筒軸に対してヒンジ部と摘み部とを９０度離すとすると、当該摘み部を起点として周方向へ開封バンドが延びると、前記中間筒部の全周のうちでヒンジ部及び開封バンドでカバーできない部分が生ずる。
そこで特許文献１では、ヒンジ部の両側に開封バンドとは別に中間筒部の上端と帽筒部の下端とを破断可能に接続する弱化線を設けているが、この構成では、開封バンドを除去した後に帽筒部を開方向へ回転させるときに、弱化線を破断させなければならず、開蓋操作に余分な力が必要となる。
また特許文献１では、一枚の帯板である開封バンドを周方向一方のみに引っ張ることで、これを基筒部及び帽筒部から引き千切るようにしているが、その際に切断箇所で開封バンドを変形させることになる。このため、開封バンドの上下の幅が大き過ぎると、これを引きちぎることに大きな力が必要となり、高齢者や子供など指の力が弱い利用者にとっては扱いにくい。その反面、開封バンドの上下の幅が小さ過ぎると、不正に開封バンドが除去されたときに、不正開封の痕跡（開封バンドの欠落）がそれほど目立たず、需要者に気づかれない可能性がある。
Since the thing of patent document 1 is comprised so that an opening band may be removed by pulling the knob | pick part attached to the edge part of the circumferential direction of an opening band to the circumferential direction one part, the location which can provide an opening band Have design constraints. For example, if the hinge part and the knob part are separated by 90 degrees from the cylinder axis of the base cylinder part as described above, when the opening band extends in the circumferential direction starting from the knob part, the entire circumference of the intermediate cylinder part A part which cannot be covered with a hinge part and an opening band arises.
Therefore, in Patent Document 1, a weakening line that connects the upper end of the intermediate tube portion and the lower end of the cap tube portion in a breakable manner is provided on both sides of the hinge portion in a breakable manner. In this configuration, the opening band is removed. After that, when the cap tube portion is rotated in the opening direction, the weakening line must be broken, and an extra force is required for the opening operation.
Moreover, in patent document 1, although it pulls off from the base cylinder part and a cap cylinder part by pulling the opening band which is one strip plate only to the circumferential direction one side, The opening band will be deformed. For this reason, if the upper and lower widths of the opening band are too large, a large force is required for tearing it off, and it is difficult for a user such as an elderly person or a child with weak finger strength. On the other hand, if the upper and lower widths of the opening band are too small, when the opening band is illegally removed, the traces of unauthorized opening (missing of the opening band) may not be so noticeable and may not be noticed by consumers. .
本発明の第１の目的は、小さい力で操作することができる封緘キャップ及び封緘容器を提供することである。
本発明の第２の目的は、開封バンドの設計上の自由度が大きい封緘キャップ及び封緘容器を提供することである。
A first object of the present invention is to provide a sealing cap and a sealing container that can be operated with a small force.
The second object of the present invention is to provide a sealing cap and a sealing container having a high degree of freedom in designing the opening band.

The opening band B includes at least a first narrow strip portion b1 between one of the pair of main transverse main separation lines 24A and the transverse auxiliary separation line 30b, and the other 24B of the pair of main transverse main separation lines and the transverse assistance. The second narrow strip portion b3 between the separation lines 30b is connected to the first narrow strip portion b1 and the second narrow strip portion b3 between the pair of longitudinal main separation lines 26A and the lateral auxiliary separation line 30b. And a folded portion b2 to be
It is formed so that it is possible to pull out the start end e1 which is the end of the first narrow strip part b1 on the opposite side to the folded part b2.
The knob 32 is attached to the start end e1.
本手段では、封緘キャップ１０の基筒部１２及び帽筒部３６に主分離線２２を介して連続する開封バンドＢに関して、開封バンドＢの上辺及び下辺に沿って一対の横向き主分離線２４Ａ、２４Ｂを、開封バンドＢの周方向の側辺に沿って一対の縦向き主分離線２６Ａ、２６Ｂを形成するとともに、開封バンドＢが少なくとも第１細帯部分ｂ１と第２細帯部分ｂ３と折り返し部ｂ２とを包含するように仕切る補助分離線３０を設けることを提案している。
補助分離線３０は、次の要件を満たすように形成されている。
（a）前記開封バンドＢの周方向の一部に、前記一対の縦向き主分離線の一方２６Ａとの間に折り返し代Ｍを残して、前記一対の横向き主分離線２４Ａ、２４Ｂと並行する横向き補助分離線３０ｂを含むこと。

（c）この折り返し部ｂ２と反対側の第１細帯部分ｂ１の端部である始端部ｅ１を引き出すことが可能であること。
そして前記始端部ｅ１には、摘み部３２が付設されており、この摘み部３２を引っ張ると、始端部を破断の起点として、第１細帯部分ｂ１、折り返し部ｂ２、第２細帯部分ｂ３が順次開封バンドＢの周囲の構造から引き千切られることにより、開封バンドＢを上下２弾に分断しながら取り外すことができる。幅の細い帯は、幅の広い帯よりも小さい力で変形させることができる。したがって開封バンドＢの少なくとも一部が、始端部ｅ１を含む第１細帯部分ｂ１及び第２細帯部分ｂ３との２段構造となっており、かつ両者を連結する折り返し部ｂ２を設けるという着想により、開封バンドＢを小さな力で開封することができる。
なお、図示例の開封バンドＢは、第２細帯部分ｂ３と連結された広帯部分ｂ４をさらに含んでいるが、これは前記着想に必須ではないため、開封バンドＢの全体を第１細帯部分ｂ１と第２細帯部分ｂ３と折り返し部ｂ２とで形成しても構わない。
In this means, with respect to the opening band B that continues to the base tube portion 12 and the cap tube portion 36 of the sealing cap 10 via the main separation line 22, a pair of lateral main separation lines 24A along the upper side and the lower side of the opening band B, 24B is formed with a pair of longitudinal main separation lines 26A and 26B along the circumferential side of the opening band B, and the opening band B is folded back with at least the first narrow band part b1 and the second narrow band part b3. It is proposed to provide an auxiliary separation line 30 for partitioning so as to include the part b2.
The auxiliary separation line 30 is formed to satisfy the following requirements.

(C) It is possible to pull out the start end e1 which is the end of the first narrow strip portion b1 on the opposite side to the folded portion b2.
The start end e1 is provided with a knob 32. When the knob 32 is pulled, the first narrow band part b1, the folded-back part b2, and the second narrow band part b3 with the start end as the starting point of breakage. Are sequentially cut off from the structure around the opening band B, so that the opening band B can be removed while being divided into two upper and lower bullets. A narrow strip can be deformed with less force than a wide strip. Accordingly, the idea is that at least a part of the unsealing band B has a two-stage structure of the first narrow band part b1 and the second narrow band part b3 including the start end part e1, and a folded part b2 for connecting the two is provided. Thus, the opening band B can be opened with a small force.
The opening band B in the illustrated example further includes a wide band part b4 connected to the second narrow band part b3. However, since this is not essential for the idea, the entire opening band B is the first narrow band part b4. You may form by the strip | belt part b1, the 2nd narrow strip part b3, and the folding | returning part b2.
「中間筒部」は、封緘キャップの基筒部１２と帽筒部３６との間の部位であり、上方から見て周方向の一部であるヒンジ部１８と、残りの部分であるＣ字形の帯状部分２０とからなる。図示例では、帯状部分２０の全体を開封バンドＢとしているが、特許文献１のようにヒンジ部１８と反対側の半周部分を開封バンドＢとし、ヒンジ部１８と開封バンドＢとの間の中間筒部の上端を、弱化線を介して帽筒部の下端に連続させた構造も本手段の技術的範囲に含まれる。
「分離線」とは、本明細書において、開封バンドＢの全体又は一部を周囲から分離する機能を有していれば足り、例えば薄肉の弱化線やミシン目として形成することができる。ミシン目の切れ目の一つを長くしてスリットとしても構わない。
「主分離線」は、開封バンドＢを、その周囲の構造から切り離すための分離線であり、開封バンドＢの四辺に沿って形成されている。
「補助分離線」は、開封バンドＢを、第１細帯部分ｂ１と第２細帯部分ｂ３と折り返し部ｂ２との順番で順次引き千切るために形成された分離線である。
図示例の補助分離線は、上下一対の横向き主分離線の一方２４Ａから縦方向に延びる縦向き補助分離線３０ａをさらに含み、この縦向き補助分離線３０ａの先端から前記折り返し部ｂ２へ前記横向き補助分離線３０ｂが延びている。そうすることで、縦向き補助分離線３０ａに対して折り返し部ｂ２と反対側に広帯部分ｂ４を形成しているが、広帯部分ｂ４を省略する場合には、縦向き補助分離線３０ａを設けずに、一対の縦主分離線２２の他方（折り返し部ｂ２と反対側の分離線）に横向き補助分離線３０ｂを連続させれば良い。
The “intermediate tube portion” is a portion between the base tube portion 12 and the cap tube portion 36 of the sealing cap, and is a hinge portion 18 that is a part in the circumferential direction when viewed from above, and a C-shape that is the remaining portion. And a belt-like portion 20. In the illustrated example, the entire band-shaped portion 20 is the opening band B. However, as in Patent Document 1, the half-circumferential portion on the opposite side of the hinge portion 18 is the opening band B, and the intermediate portion between the hinge portion 18 and the opening band B is shown in FIG. A structure in which the upper end of the cylindrical portion is connected to the lower end of the cap cylindrical portion via a weakening line is also included in the technical scope of this means.
In this specification, the “separation line” is sufficient if it has a function of separating the whole or part of the unsealing band B from the surroundings, and can be formed as, for example, a thin weakened line or perforation. One slit in the perforation may be lengthened to form a slit.
The “main separation line” is a separation line for separating the opening band B from the surrounding structure, and is formed along the four sides of the opening band B.
The “auxiliary separation line” is a separation line formed to sequentially tear the opening band B in the order of the first narrow band part b1, the second narrow band part b3, and the folded part b2.
The auxiliary separation line in the illustrated example further includes a vertical auxiliary separation line 30a extending in the vertical direction from one of the pair of upper and lower horizontal main separation lines 24A, and the horizontal direction from the tip of the vertical auxiliary separation line 30a to the folded portion b2 The auxiliary separation line 30b extends. By doing so, the wide band part b4 is formed on the side opposite to the folded part b2 with respect to the vertical auxiliary separation line 30a. However, when the wide band part b4 is omitted, the vertical auxiliary separation line 30a is The horizontal auxiliary separation line 30b may be continued to the other of the pair of vertical main separation lines 22 (separation line opposite to the folded portion b2) without being provided.

この構成とする場合には、前記主分離線２２のうち、少なくとも前記ヒンジ部１８の両側縁と重なる一対の縦向き主分離線２６Ａ、２６Ｂをスリットとすることが望ましい。そうすることで、開封バンドＢを引き千切るときの力がヒンジ部１８に作用し、ヒンジ部１８を損傷させることを防止するためである。
In this means, the pair of longitudinal main separation lines 26A, 26B of the opening band B are disposed on both side edges of the hinge portion 18 so that the entire band-shaped portion 20 is formed in the opening band B. . According to this configuration, as in Patent Document 1, the upper end of the intermediate cylinder part and the lower end of the cap cylinder part 36 are continuously connected via the weakening line between the hinge part and the opening band in the circumferential direction of the sealing cap. Compared to the structure that has been made, when the cap tube portion 36 is rotated in the opening direction after removing the opening band, it is avoided that the rotation operation becomes hard (the rotation resistance increases) to break the weakening line. Can do.
In the case of this configuration, it is desirable that a pair of longitudinal main separation lines 26 </ b> A and 26 </ b> B that overlap at least both side edges of the hinge portion 18 among the main separation lines 22 be slits.

The hinge portion is connected to the cap cylinder portion 36 via the first horizontal main separation line 24A, and further via the first vertical main separation line 26A and the second vertical main separation line 26B formed on both sides in the circumferential direction. 18 is continuous. However, these structures can be changed as appropriate.
As shown in FIG. 3A, the auxiliary separation line 30 includes a vertical auxiliary separation line 30a that hangs down from an intermediate portion of the first horizontal main separation line 24A to an intermediate position in the vertical width of the opening band B, and the vertical direction. It is formed by a lateral auxiliary separation line 30b extending horizontally from the lower end of the auxiliary separation line 30a toward the first vertical main separation line 26A. A folding allowance M is assumed between the front end of the horizontal auxiliary separating line 30b and the first vertical main separating line 26A as shown in FIG.
By providing the main separation line 22 and the auxiliary separation line 30, the opening band B is
(A) a first narrow strip portion b1 formed between the first lateral main separation line 24A and the lateral auxiliary separation line 30b;
(B) a second narrow strip portion b3 formed between the second lateral main separation line 24B and the lateral auxiliary separation line 30b;
(C) a folded portion b2 between one of the pair of longitudinal main separation lines 26A and the lateral auxiliary separation line 30b and connecting the first narrow strip portion b1 and the second narrow strip portion b3;
(D) a wide band portion b4 located on the opposite side of the folded portion b2 with respect to the vertical auxiliary separation line 30a and connected to the second narrow band portion b3.
This configuration is shown in FIG. 3B by developing the entire circumference of the intermediate cylinder portion 16 in a panoramic shape. In the preferred illustrated example, the first narrow band portion b1 and the second narrow band portion b3 have the same vertical width, but the form thereof can be changed as appropriate.
With this configuration, the unsealing band B has the first narrow strip portion b1 → the folded portion b2 → the second narrow strip, as shown in FIGS. 5 (A), 5 (B), and 6 (A). It can be stripped in the order of the band part b3 → the wide band part b4 and developed into a series of strings.
As shown in FIG. 2, the start end portion e1 of the series of string-like structures is the end portion of the first narrow strip portion b1 near the vertical auxiliary separation line 30a, and the end portion e2 is the second vertical main portion. The end of the wide band portion b4 near the separation line 26B.
A knob 32 is attached to the start end e1. As shown in FIG. 1, the illustrated knob 32 is formed of a protrusion 32 a that protrudes outward from the starting end e <b> 1 and a knob 32 b that extends from the tip of the protrusion to both sides in the circumferential direction. In a preferred illustrated example, as shown in FIG. 4B, an inclined surface 31 is formed at a position below the knob 32b in the wide band portion b4 so that the knob 32b can be easily picked.

Are formed with a U-shaped first slit 28A. The first slit 28A surrounds the outer side of the folded part b2, which makes it easier to pull the folded part b2 outward when the opening band B is broken.
The second vertical main separation line 26B forms a linear second slit 28B. The first horizontal main separation line 24A and the second vertical main separation line 26B form both side edges in the circumferential direction of the hinge portion 18, and the opening band B is broken by drilling them as slits. In this case, the hinge portion 18 can be prevented from being damaged.
前記摘み部３２は、好適な図示例では、前記基筒部１２の筒軸に対してヒンジ部１８から約９０度離れた位置に、すなわち、封緘キャップ１０の左右方向に配置することが望ましい。そうすることで、図２に点線で示す金型のパーティングラインＰ上に摘み部３２が位置するように設計することにより、指掛け部４４を含む封緘キャップ１０の前半部外面を成形する金型と、ヒンジ部を含む封緘キャップ１０の後半部の外面を成形する金型とを前後方向に外すことができ、型抜きが容易となる。 In the preferred illustrated example, the knob portion 32 is preferably disposed at a position about 90 degrees away from the hinge portion 18 with respect to the tube axis of the base tube portion 12, that is, in the left-right direction of the sealing cap 10. By doing so, a mold that molds the outer surface of the front half of the sealing cap 10 including the finger hooks 44 by designing the knob 32 to be positioned on the parting line P of the mold indicated by the dotted line in FIG. And the metal mold | die which shape | molds the outer surface of the second half part of the sealing cap 10 containing a hinge part can be removed in the front-back direction, and die cutting becomes easy.
前記摘み部３２を基筒部１２の筒軸に対してヒンジ部１８から約９０度離れた位置に設置するためには、図３（Ｂ）に示す如く、前記開封バンドＢのうちで前記摘み部３２より周方向の一方に位置するバンド部分を、中間筒部１６の全周長さの約３／４程度の長手部Ｌに形成し、また周方向の他方に位置するバンド部分を、中間筒部１６の全周長さの約１／４程度の短手部Ｓに形成すると良い。
本実施形態では、前記長手部Ｌに、第１細帯部分ｂ１と第２細帯部分ｂ３と折り返し部ｂ２を形成し、短手部Ｓを広帯部分ｂ４に形成している。これにより、第１細帯部分ｂ１及び第２細帯部分ｂ３が２段に重なるために小さな力で破断できる範囲が広くなる。
なお、図示例では、第１帯板部分ｂ１を上側に、また第２帯板部分ｂ２を下側に配置しているが、開封バンドの第１横向き主分離線２４Ａ、第２横向き分離線２４Ｂ，縦向き補助分離線３０ａ、第１帯板部分ｂ１及びまた第２帯板部分ｂ２の相互の位置関係を上下反転させた構造としても、同様の作用が得られる。
In order to install the knob portion 32 at a position about 90 degrees away from the hinge portion 18 with respect to the cylinder axis of the base cylinder portion 12, as shown in FIG. A band portion located on one side in the circumferential direction from the portion 32 is formed in a longitudinal portion L that is about 3/4 of the entire circumferential length of the intermediate cylindrical portion 16, and a band portion located on the other side in the circumferential direction is It is good to form in the short part S about about 1/4 of the perimeter length of the cylinder part 16. FIG.
In the present embodiment, the first narrow strip portion b1, the second narrow strip portion b3, and the folded portion b2 are formed in the longitudinal portion L, and the short portion S is formed in the wide strip portion b4. Thereby, since the 1st narrow strip part b1 and the 2nd narrow strip part b3 overlap in 2 steps | paragraphs, the range which can be fracture | ruptured with a small force becomes wide.
In the illustrated example, the first strip portion b1 is disposed on the upper side and the second strip portion b2 is disposed on the lower side. However, the first transverse main separation line 24A and the second transverse separation line 24B of the opening band are provided. A similar effect can be obtained even if the vertical auxiliary separation line 30a, the first strip portion b1, and the second strip portion b2 are vertically inverted.
前記構成において、図３（Ａ）に示す状態から前記摘み部３２を摘まんで、長手部Ｌ側へ引張り、さらに図５（Ａ）に矢示するように後外方へ引き出すと、長手部Ｌにおいて第１横向き主分離線２４Ａ及び横向き補助分離線３０ｂが破断することにより、第１細帯部分ｂ１が折り返し部ｂ２付近まで引き出される。
前記破断箇所が折り返し部ｂ２に到達した後に、摘み部３２を引っ張る方向を後外方から中間筒部１６の半径方向外側へ変えると、折り返し部ｂ２の回りには第１スリット２８Ａが穿設されているため、図５（Ｂ）に示すように、折り返し部ｂ２が外側へ引き出され、次に摘み部３２を前外方へ引っ張ると、第２横向き主分離線２４Ｂが破断することにより、第２細帯部分ｂ３が引き出される。
第２細帯部分ｂ３の全体が引き出された後も摘み部３２を同じ方向へ引っ張ると、短手部Ｓにおいて第１横向き主分離線２４Ａ及び第２横向き主分離線２４Ｂが破断することにより、広帯部分ｂ４が外側へ引き出される。破断箇所が第２縦向き補助分離線３０ａとして形成された第２スリットに到達すると、広帯部分ｂ４が封緘キャップ１０から完全に離脱し、開封バンドＢが除去される。
なお、第１細帯部分ｂ１及び第２細帯部分ｂ３は引き出し作業の途中で変形するが、単一の開封バンドを引き出す場合と比べて、上下方向の巾が小さいため、引き出しに要する力は小さい。
また開封バンドを除去する作業は、破断箇所が折り返し部に至るまでは従来の技術と同じであるので、従来品に慣れた使用者にとっても戸惑いが少ない。
In the above configuration, when the knob 32 is picked from the state shown in FIG. 3 (A), pulled to the longitudinal part L side, and further pulled out rearward as shown by an arrow in FIG. 5 (A), the longitudinal part L When the first horizontal main separation line 24A and the horizontal auxiliary separation line 30b are broken, the first narrow strip portion b1 is pulled out to the vicinity of the folded portion b2.
When the direction of pulling the knob 32 is changed from the rear outer side to the outer side in the radial direction of the intermediate cylinder part 16 after the broken part reaches the folded part b2, a first slit 28A is formed around the folded part b2. Therefore, as shown in FIG. 5 (B), when the folded portion b2 is pulled outward and then the knob portion 32 is pulled forward and outward, the second lateral main separation line 24B breaks, The two narrow strip portions b3 are pulled out.
When the knob 32 is pulled in the same direction even after the entire second thin strip portion b3 is pulled out, the first lateral main separation line 24A and the second lateral main separation line 24B are broken in the short portion S, The wide band part b4 is pulled out to the outside. When the broken portion reaches the second slit formed as the second vertical auxiliary separating line 30a, the wide band portion b4 is completely detached from the sealing cap 10 and the opening band B is removed.
The first narrow band portion b1 and the second narrow band portion b3 are deformed in the middle of the pulling work, but the vertical width is smaller than when pulling a single opening band, so the force required for pulling is small.
Moreover, since the operation | work which removes an opening band is the same as the prior art until a broken part reaches a folding | returning part, there is little confusion for the user accustomed to the conventional product.
以下、本発明の他の実施形態に係る封緘容器を説明する。これらの説明において第１実施形態と同じ構成に関しては解説を省略する。 Hereinafter, a sealed container according to another embodiment of the present invention will be described. In these descriptions, the description of the same configuration as that of the first embodiment is omitted.
図７から図１１は、本発明の第２実施形態に係る封緘容器を示している。本実施形態では、第１実施形態と異なり、図７に示す如く、短手部Ｓに、第１細帯部分ｂ１と第２細帯部分ｂ３と折り返し部ｂ２を形成し、また図１０に示す如く、長手部Ｌを広帯部分ｂ４に形成している。
この構成では、図８の状態から摘み部３２を引っ張って、開封バンドＢを毟り取るときに、第１細帯部分ｂ１、折り返し部ｂ２、第２細帯部分ｂ３、広帯部分ｂ４の順序で引き出される点は同じであるが、図９に示す状態から、摘み部３２を、第１実施形態とは逆に短手部Ｓ側へ引張り、同図の図１１（Ａ）、図１１（Ｂ）及び図１１（Ｃ）に示す引き出し操作の始めの段階で短手部Ｓが破断し、引き出し操作の後の段階で長手部Ｌが破断されることが異なる。
これにより、第１細帯部分ｂ１と折り返し部ｂ２と第２細帯部分ｂ３と広帯部分ｂ４とが一連の紐状体として引き出されたときに、その紐状体の全長を短くすることができ、開封バンドＢの除去作業を手早く行うことができる。
7 to 11 show a sealed container according to the second embodiment of the present invention. In the present embodiment, unlike the first embodiment, as shown in FIG. 7, the first narrow strip portion b1, the second narrow strip portion b3, and the folded portion b2 are formed in the short portion S, as shown in FIG. Thus, the longitudinal portion L is formed in the wide band portion b4.
In this configuration, when the picking portion 32 is pulled from the state shown in FIG. 8 and the opening band B is scraped off, the first narrow strip portion b1, the folded portion b2, the second narrow strip portion b3, and the wide strip portion b4 are arranged in this order. Although the point pulled out is the same, the knob | pick part 32 is pulled to the short part S side contrary to 1st Embodiment from the state shown in FIG. 9, and FIG. 11 (A) of FIG. ) And FIG. 11C, the short portion S is broken at the beginning of the pulling operation, and the long portion L is broken at the stage after the pulling operation.
Thereby, when the 1st narrow strip part b1, the folding | returning part b2, the 2nd narrow strip part b3, and the wide strip part b4 are pulled out as a series of string-like bodies, the full length of the string-like body can be shortened. The opening band B can be removed quickly.
