Description

本願発明は、収納体及び収納体の開封明示用チャックに関するものである。   The present invention relates to a storage body and a chuck for clearly showing opening of the storage body.

線上の嵌合部を揺する開閉用チャックは、袋の開閉を繰り返し行うことができる点で、極めて有用なものとして、従来より広く用いられている。ところが、この開閉用チャックの利点は、袋内部への悪戯を改竄の痕跡を明示が困難であるという欠点になる。そのため、開封されたことを明示する観点から、特許文献1及び2に示すような提案がなされている。これらの提案は、開閉用チャック以外の袋の一部を溶着などで封をすると共に、その封止部分の近くに開閉用のミシン目等の弱め線を設けたものであり、袋を開くためには、開閉用チャックを開くと共に、その弱め線を破るようにしたものである。
また、特許文献3は、スライダ付きの開閉チャックにあって、スライダは、一回だけ破断可能ないたずら証明特徴部が破断されるまでは、上記閉位置から動くことができず、あるいは、スライダが上記閉位置から動くことにより、いたずら証明特徴部が破断されるようにしたものが提案されている。
ところが、これらの提案は、内容物を袋に収納した後に、溶着や接着剤などで袋の封止を行うか(特許文献1、2)、チャックを溶着などで取り付けるようにする必要があり(特許文献3)、内容物の収納後に封止のための手間がかかったり、特別な装置が必要となる。
Opening and closing chucks that swing the fitting portion on the line have been widely used in the past as being extremely useful in that the bag can be repeatedly opened and closed. However, the advantage of the opening / closing chuck is that it is difficult to clearly show the trace of tampering inside the bag. Therefore, proposals as shown in Patent Documents 1 and 2 have been made from the viewpoint of clearly indicating that the package has been opened. In these proposals, a part of the bag other than the opening and closing chuck is sealed by welding or the like, and a weakening line such as a perforation for opening and closing is provided near the sealing portion, so that the bag can be opened. In this case, the opening / closing chuck is opened and the weakening line is broken.
Further, Patent Document 3 is an open / close chuck with a slider, and the slider cannot move from the closed position until the mischievous proof feature that can be broken only once is broken, or the slider does not move. Proposals have been made in which the mischievous proof feature is broken by moving from the closed position.
However, in these proposals, after the contents are stored in the bag, it is necessary to seal the bag with welding or an adhesive (Patent Documents 1 and 2), or to attach the chuck by welding or the like ( Patent Document 3), it takes time for sealing after the contents are stored, or a special device is required.

以下、図面に基づき本願発明の実施の形態を説明する。
図1に示す開封明示用チャック10は、一対の合成樹脂製の第1チャック半部11と第2チャック半部21とからなる。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The unwrapping manifestation chuck 10 shown in FIG. 1 comprises a pair of synthetic resin first chuck half 11 and second chuck half 21.

第1チャック半部11は、雄嵌合部12と、この雄嵌合部12を支持する雄用支持部13とを備える。雄用支持部13は基部14と中間部15とを備える。雄嵌合部12と基部14とをつなぐ部分が中間部15である。基部14の少なくとも一部は溶着や接着剤等の接着部分17によって、収納袋31を構成するシートに固定される。また収納袋31と第1チャック半部11とを一体に形成することもできる。これらの形状は、その機能を果たし得る範囲で適宜変更して実施できるが、この例では、基部14は上下方向(内容物の出し入れ方向)に幅のある帯状をなし、この基部14の上下方向の中程から細幅の中間部15が左右方向(内容物の出し入れ方向と交わる方向)に伸び、その先端に中間部15よりも上下幅の大きな雄嵌合部12が形成されている。なお、中間部15を設ける位置は適宜変更でき、基部14の中程に限らず、上下方向にずれていてもよい。また雄嵌合部12の嵌合機能が果たせる場合には、中間部15を省略して、基部14に雄嵌合部12を直接形成するようにしてもよい。接着部分17は、基部14の上下に1箇所ずつとしているが、基部14の全体を接着してもよく、適宜変更し得る。   The first chuck half 11 includes a male fitting portion 12 and a male support portion 13 that supports the male fitting portion 12. The male support portion 13 includes a base portion 14 and an intermediate portion 15. A portion connecting the male fitting portion 12 and the base portion 14 is an intermediate portion 15. At least a part of the base portion 14 is fixed to a sheet constituting the storage bag 31 by an adhesive portion 17 such as welding or adhesive. Further, the storage bag 31 and the first chuck half 11 can be integrally formed. These shapes can be implemented by changing as appropriate within the range in which the function can be achieved. In this example, the base portion 14 has a band shape having a width in the vertical direction (the direction in which the contents are put in and taken out). A middle portion 15 having a narrow width extends from the middle in the left-right direction (direction intersecting the direction in which the contents are put in and out), and a male fitting portion 12 having a larger vertical width than the middle portion 15 is formed at the tip. The position where the intermediate portion 15 is provided can be changed as appropriate, and is not limited to the middle of the base portion 14 and may be shifted in the vertical direction. Further, when the fitting function of the male fitting portion 12 can be fulfilled, the middle fitting portion 15 may be omitted and the male fitting portion 12 may be directly formed on the base portion 14. Although the adhesion part 17 is made into one place each on the upper and lower sides of the base 14, the whole base 14 may be adhere | attached and it can change suitably.

第2チャック半部21は、雌嵌合部22と、この雌嵌合部22を支持する雌用支持部23とを備える。雌嵌合部22は、弾性変形することによって、雄嵌合部12を受容し強制嵌合する。雌用支持部23は基部24と中間部25とを備える。雌嵌合部22と基部24とをつなぐ部分が中間部25である。基部24の少なくとも一部は溶着や接着剤等の接着部分27によって収納袋31を構成するシートに固定される。また収納袋31と第2チャック半部21とを一体に形成することもできる。これらの形状は、その機能を果たし得る範囲で適宜変更して実施できるが、この例では、基部24は上下方向(内容物の出し入れ方向)に幅のある帯状をなし、この基部24の上下方向の中程から細幅の中間部25が左右方向(内容物の出し入れ方向と交わる方向)に伸び、その先端に上下方向に二股状に分かれた雌嵌合部22が形成され、この雌嵌合部22に雄嵌合部12が強制嵌合される。なお、中間部25を設ける位置は適宜変更でき、基部24の中程に限らず、上下方向にずれていてもよい。また雌嵌合部22の嵌合機能が果たせる場合には、中間部25を省略して、基部24に雌嵌合部22を直接形成するようにしてもよい。なお、接着部分27は、基部24の上下に1箇所ずつとしているが、基部24の全体を接着してもよく、適宜変更し得る。   The second chuck half 21 includes a female fitting portion 22 and a female support portion 23 that supports the female fitting portion 22. The female fitting portion 22 is elastically deformed to receive and forcibly fit the male fitting portion 12. The female support portion 23 includes a base portion 24 and an intermediate portion 25. A portion connecting the female fitting portion 22 and the base portion 24 is an intermediate portion 25. At least a part of the base 24 is fixed to a sheet constituting the storage bag 31 by an adhesive portion 27 such as welding or adhesive. Further, the storage bag 31 and the second chuck half 21 can be integrally formed. These shapes can be changed and implemented as appropriate within the range in which the function can be achieved. In this example, the base portion 24 has a band shape that is wide in the vertical direction (the direction in which the contents are put in and out). An intermediate portion 25 having a narrow width extends from the middle to the left-right direction (the direction intersecting with the content insertion / removal direction), and a female fitting portion 22 that is bifurcated in the vertical direction is formed at the tip thereof. The male fitting portion 12 is forcibly fitted to the portion 22. The position where the intermediate portion 25 is provided can be changed as appropriate, and is not limited to the middle of the base portion 24, and may be shifted in the vertical direction. Further, when the fitting function of the female fitting portion 22 can be achieved, the intermediate portion 25 may be omitted and the female fitting portion 22 may be formed directly on the base portion 24. In addition, although the adhesion part 27 is made into one place on the upper and lower sides of the base 24, the whole base 24 may be adhere | attached and it can change suitably.

第1チャック半部11及び第2チャック半部21の少なくとも何れか一箇所に、弱め線16、26が設けられている。この弱め線16、26は、雄嵌合部12、雄用支持部13、雌嵌合部22、雌用支持部23のいずれに設けてもよいが、開封の確認の容易性からは雄用支持部13、雌用支持部23に設ける方が有利であり、図1(A)に示す例では、ミシン目からなる弱め線16、26が基部14、24に設けられている。詳しくは、接着部分17と接着部分17との間(図では、第1チャック半部11の基部14の下端寄り)と、接着部分27と接着部分27との間(第2チャック半部21の基部24の上端寄り)に設けられている。この例では、両弱め線16、26を、第1チャック半部11と第2チャック半部21との双方に設けているが、いずれか一方にのみ設ければ足りる。また、第1チャック半部11の基部14の上端寄りと、第2チャック半部21の基部24の下端寄りに設けることもできる。   At least one of the first chuck half 11 and the second chuck half 21 is provided with weakening lines 16 and 26. The weakening lines 16 and 26 may be provided on any of the male fitting portion 12, the male support portion 13, the female fitting portion 22, and the female support portion 23. It is advantageous to provide the support portion 13 and the female support portion 23, and in the example shown in FIG. 1A, the weakening lines 16 and 26 formed of perforations are provided on the base portions 14 and 24. Specifically, between the bonding portion 17 and the bonding portion 17 (in the drawing, near the lower end of the base portion 14 of the first chuck half 11) and between the bonding portion 27 and the bonding portion 27 (of the second chuck half 21). It is provided near the upper end of the base 24. In this example, the two weakening lines 16 and 26 are provided on both the first chuck half 11 and the second chuck half 21, but it is sufficient if they are provided only on one of them. Further, it may be provided near the upper end of the base 14 of the first chuck half 11 and near the lower end of the base 24 of the second chuck half 21.

また、図1(B)に示すように、ミシン目からなる弱め線16に限らず、凹溝からなる弱め線26を形成することもできる。この例では雄用支持部13の中間部15及び雌用支持部23の中間部25に設けている。これらの弱め線16、26の形状・構造は、種々変更して実施できる。図1(B)の例では、弱め線16を、第1チャック半部11に対する貫通部分を断続的に設けたミシン目としており、弱め線26を、肉厚を薄くした破れやすくした凹溝状部分としているが、ミシン目の貫通部分間を凹溝状部分で繋ぐような併用型としてもよい。貫通部分の形状も適宜変更でき、破れ方向に沿った長孔でもよく、方向性のない丸孔でもよく、破れ方向と交わる方向に伸びる孔でもよい。凹溝の断面形状も楔形、U字状など適宜変更できる。また、弱め部は、線状のものに限らず、例えば、中間部15、25の厚みを全体的に薄いものとして、破断しやすいものとしてもよい。また、基部14、24を収納袋31のシートと接着する接着部分17、27を、脆弱なものとしてもよい。   Further, as shown in FIG. 1 (B), not only the weak line 16 made of a perforation but also a weak line 26 made of a concave groove can be formed. In this example, it is provided in the intermediate portion 15 of the male support portion 13 and the intermediate portion 25 of the female support portion 23. The shape and structure of the weakening lines 16 and 26 can be implemented with various changes. In the example of FIG. 1B, the weakening line 16 has a perforation in which a penetrating portion with respect to the first chuck half portion 11 is provided intermittently, and the weakening line 26 has a concave groove shape with a reduced thickness. Although it is a part, it is good also as a combination type which connects the perforation part between perforations by a concave-groove part. The shape of the penetrating portion can also be changed as appropriate, and it may be a long hole along the tearing direction, a round hole with no directivity, or a hole extending in a direction intersecting with the tearing direction. The cross-sectional shape of the groove can also be appropriately changed, such as a wedge shape or a U shape. Further, the weakened portion is not limited to a linear one, and for example, the intermediate portions 15 and 25 may be thin as a whole, and may be easily broken. Moreover, it is good also considering the adhesion parts 17 and 27 which adhere | attach the base parts 14 and 24 with the sheet | seat of the storage bag 31 as a weak thing.

重要なことは、弱め部(弱め線16、26)の破断強度よりも、雄嵌合部12と雌嵌合部22との嵌合強度の方が大きくなるように設計することである。簡単に言えば、収納袋31を開封しようとして収納袋31のシート又は開封明示用チャック10を引っ張ったとき、雄嵌合部12と雌嵌合部22との嵌合が外れる前に、弱め線16、26が破れることである。この嵌合強度は、破断強度よりも僅かにでも大きければ足りるが、加工や材質のばらつきによる不安定性を排除する観点からは、1.5倍以上の差を設けることが望ましい。   What is important is that the fitting strength between the male fitting portion 12 and the female fitting portion 22 is designed to be larger than the breaking strength of the weakened portions (weakening lines 16 and 26). In short, when the storage bag 31 is pulled to pull the sheet of the storage bag 31 or the chuck 10 for revealing opening, the weakening line is removed before the male fitting portion 12 and the female fitting portion 22 are disengaged. 16 and 26 are torn. This fitting strength is only required to be slightly larger than the breaking strength, but it is desirable to provide a difference of 1.5 times or more from the viewpoint of eliminating instability due to variations in processing and materials.

次に、図2は、上記の開封明示用チャック10と、通常の開閉用チャック33を併用した例である。この開閉用チャック33は、上記の開封明示用チャック10と実質的に同じものを用いることができるが、弱め線16、26が設けられていない点が、相違する。図の例では、収納袋31の開口部32付近において、上方(収納袋31の開口端に近い方)に開封明示用チャック10を取り付け、その下方(収納袋31の奥の方)に開閉用チャック33を取り付けたものである。これによって、故意又は過失によって、開封明示用チャック10の弱め線16、26を破った場合にも、開閉用チャック33が開かれない限り、袋の密封性を維持することができる。但し、開閉用チャック33を開封明示用チャック10よりも上方に設けることもでき、場合によっては、開封明示用チャック10の上下両側に開閉用チャック33を設けてもよい。   Next, FIG. 2 is an example in which the above-described opening and closing chuck 10 and a normal opening and closing chuck 33 are used in combination. The opening / closing chuck 33 can be substantially the same as the above-described opening and clarifying chuck 10 except that the weakening lines 16 and 26 are not provided. In the example of the figure, in the vicinity of the opening 32 of the storage bag 31, the opening clarification chuck 10 is attached on the upper side (the side closer to the opening end of the storage bag 31), and for opening and closing the lower side (the back side of the storage bag 31). A chuck 33 is attached. Thus, even when the weakening lines 16 and 26 of the opening indication chuck 10 are deliberately or accidentally broken, the sealing performance of the bag can be maintained as long as the opening and closing chuck 33 is not opened. However, the opening / closing chuck 33 may be provided above the opening manifestation chuck 10, and in some cases, the opening / closing chucks 33 may be provided on both upper and lower sides of the opening manifestation chuck 10.

また、開封明示用チャック10のみで実施した場合、移送中の振動や衝撃によって内容物が開口から飛び出そうとしたり、袋の内圧が上昇したりして、弱め線16、26が破れてしまう場合があり得る。これに対して、開閉用チャック33を収納袋31の内部側に設けておくことによって、弱め線16、26が不用意に破れてしまうことを防止する。これによって、弱め線16、26が破られた原因が、外部からの悪戯や不正使用の目的か、移送中などの衝撃や内圧上昇によるものかが、わからなくなってしまうことを防止する。
特に、この例では、開閉用チャック33のシートに対する固定に関して、一方の基部34の接着については、上方側の第1接着部分36と下方側の第2接着部分37との双方で固定しているのに対して、他方の基部35の接着については、上方側の第3接着部分38のみとし、下方側はシートと接着されていない。これによって、収納袋31の密封性が高い場合に、収納袋31が圧縮される等して袋の内圧が高まった際、開閉用チャック33の嵌合が外れることを防止できる。即ち、接着箇所を、上方側の第3接着部分38のみとしておくことによって、収納袋31の内圧が高まった場合に、他方の基部35の下方側が収納袋31のシートから離れて、一方の基部34に近づく形となる。その結果、内圧は第3接着部分38に直接かかり易くなり、開閉用チャック33の嵌合部分を分離させる方向には直接働き難くなり、他方の基部35の下方を接着する場合に比して、嵌合部分の強度が増加する。
Moreover, when it is carried out only with the chuck 10 for clearly showing the opening, the weakening lines 16 and 26 may be broken because the contents try to jump out of the opening due to vibration or impact during transfer or the internal pressure of the bag rises. possible. On the other hand, providing the opening and closing chuck 33 on the inner side of the storage bag 31 prevents the weakening lines 16 and 26 from being inadvertently broken. Thus, it is possible to prevent the fact that the cause of the breakage of the weakening lines 16 and 26 from the outside is the purpose of mischief or illegal use from the outside, or due to an impact during transfer or an increase in internal pressure.
In particular, in this example, regarding the fixing of the opening / closing chuck 33 to the sheet, the bonding of one base 34 is fixed by both the upper first bonding portion 36 and the lower second bonding portion 37. On the other hand, the other base 35 is bonded only to the upper third bonding portion 38, and the lower side is not bonded to the sheet. Thereby, when the storage bag 31 has high sealing performance, it is possible to prevent the opening / closing chuck 33 from being disengaged when the storage bag 31 is compressed and the internal pressure of the bag increases. That is, when the internal pressure of the storage bag 31 is increased by leaving only the upper third bonding portion 38 as the bonding location, the lower side of the other base portion 35 is separated from the sheet of the storage bag 31 and the one base portion 34 is approaching. As a result, the internal pressure is likely to be directly applied to the third bonding portion 38, and it is difficult to work directly in the direction in which the fitting portion of the opening / closing chuck 33 is separated, compared to the case where the lower portion of the other base portion 35 is bonded, The strength of the fitting portion increases.

次に、図3は、上記の開封明示用チャック10と開閉用チャック33とを一つのチャックとして形成した併用チャック41の例である。具体的には、第1チャック半部11と第2チャック半部21のそれぞれに、雄嵌合部12、雌嵌合部22及び中間部15、25を上下に2組設ける。これらの雌雄の嵌合部12、22と中間部15、25に対する基部は上下に連続した併用基部42、43とする。そして、上下何れかの一方のチャックの嵌合部に対して、弱め線16、26を設ける。弱め線16、26を設ける位置は、先の例と同様、適宜変更できるが、この例では、上方の雄用支持部13(及び/又は雌用支持部23)の中間部15、25に設けている。この弱め線は、基部42、43に設けることもできるが、その場合、弱め線が破断された後にも、一つの嵌合部は機能するように設ける必要がある。具体的には、基部42、43の一部を、収納袋31のシートに対する接着部分とした場合、その接着部分から一つの中間部15、25とこれにつながる雄嵌合部12、雌嵌合部22とを除いた部分に、弱め線を設ける。これによって、弱め線が破断された後にも、少なくともひとつの雌雄の嵌合部12、22は、接着部分とつながっている状態を維持することができ、開閉可能なチャックとして機能することができる。   Next, FIG. 3 is an example of the combined chuck 41 in which the above-described opening and closing chuck 10 and the opening and closing chuck 33 are formed as one chuck. Specifically, two sets of a male fitting part 12, a female fitting part 22, and intermediate parts 15 and 25 are provided on the first chuck half part 11 and the second chuck half part 21 in the vertical direction. The base portions for the male and female fitting portions 12 and 22 and the intermediate portions 15 and 25 are combined base portions 42 and 43 that are continuous in the vertical direction. And the weakening lines 16 and 26 are provided with respect to the fitting part of one of the upper and lower chucks. The positions where the weakening lines 16 and 26 are provided can be changed as appropriate, as in the previous example, but in this example, they are provided in the intermediate parts 15 and 25 of the upper male support part 13 (and / or the female support part 23). ing. The weakening line can be provided in the base portions 42 and 43. In this case, it is necessary to provide one fitting portion so that it functions even after the weakening line is broken. Specifically, when a part of the base parts 42 and 43 is an adhesive part to the sheet of the storage bag 31, one intermediate part 15 and 25 from the adhesive part and the male fitting part 12 and the female fitting connected thereto. A weak line is provided in a portion excluding the portion 22. As a result, even after the weakening line is broken, at least one of the male and female fitting portions 12 and 22 can maintain a state of being connected to the bonded portion, and can function as an openable / closable chuck.

以上、本願の開封明示用チャックを用いた収納体にあっては、収納袋31等の収納体の開口部32等から、内容物(物品に限らず、液体、気体なども含む)を収納した後、開封明示用チャック10を閉じる。この簡単で素早い作業のみで、収納袋31の封緘が完了する。悪戯などの不正行為が収納体の内容物に対して行なわれようとして、開口部32を開くと、雌雄の嵌合部12、22が外れる前に、弱め線16、26が破れる。その結果、予定外の不正なアクセスの痕跡が残るものであり、安全性の向上に寄与することができるものである。 As described above, in the storage body using the opening manifestation chuck of the present application, the contents (including not only articles but also liquid and gas) are stored from the opening 32 of the storage body such as the storage bag 31. Thereafter, the unsealing chuck 10 is closed. The sealing of the storage bag 31 is completed only by this simple and quick work. If the opening 32 is opened so that an illegal act such as mischief is performed on the contents of the container, the weakening lines 16 and 26 are broken before the male and female fitting parts 12 and 22 are released. As a result, an unscheduled unauthorized access trace remains, which can contribute to improvement of safety.
