Description

本発明は、易剥離シールで隔離された２以上の収容室を備える複室容器に関する。   The present invention relates to a multi-chamber container including two or more storage chambers separated by an easily peelable seal.

従来、使用時に開通可能な易剥離シールにより隔離された２以上の収容室を備える複室容器は、種々のものが開発されている。なかでも、可撓性プラスチックからなる扁平なバッグ形態の複室容器は、例えば、輸液バッグとして医療現場において汎用されている。
しかし、このような扁平なバッグ形態の複室容器は、易剥離シールにより形成された隔壁部分（以下、隔壁弱シール部という。）と、複室容器の周縁に設けられる強シール部（以下、周縁強シール部という。）との交点付近で強度が低下することが知られており、複室容器の耐久性の向上が技術的課題となっている。 Conventionally, various types of multi-chamber containers having two or more storage chambers separated by an easily peelable seal that can be opened during use have been developed. Among these, a flat-chambered multi-chamber container made of a flexible plastic is widely used in the medical field as an infusion bag, for example.
However, such a flat bag-shaped multi-chamber container has a partition wall portion formed by an easy peel seal (hereinafter referred to as a “partition wall weak seal portion”), and a strong seal portion (hereinafter referred to as a “separate wall weak seal portion”). It is known that the strength decreases in the vicinity of the intersection with the peripheral strong seal portion.) Improvement of the durability of the multi-chamber container is a technical problem.

一方、上記の技術的課題を解決するために、隔壁弱シール部と周縁強シール部との交点に、上記交点付近を補強するための強シール部（以下、補助強シール部という。）を設けることが検討されており、様々な形状の補助強シール部が提案されている（特許文献１〜４、非特許文献１参照）。
また、例えば、高カロリー輸液などの投与に際して、さらに、少量のビタミン類や微量元素製剤を併せて投与する場合には、あらかじめ複室容器の一方の収容室内に、隔壁弱シール部の開裂に伴って開封される小袋を設けておき、この小袋にビタミン類や微量元素製剤を収容することが試みられている（特許文献５）。

Therefore, auxiliary strong seal portions having various shapes have been proposed (see Patent Documents 1 to 4 and Non-Patent Document 1).
In addition, for example, when administering a high-calorie infusion solution or the like, when a small amount of vitamins or trace element preparation is also administered, in advance in the one storage chamber of the multi-chamber container, along with the cleavage of the weak seal part of the septum An attempt has been made to accommodate a vitamin or a trace element preparation in a sachet to be opened in advance (Patent Document 5).
Japanese Utility Model Publication No. 62-3466 JP-A-8-168514 JP 2001-54553 A JP 2002-200140 A International Publication No. 99/39679 Pamphlet Design Registration No. 1237016

しかるに、特許文献１〜４および非特許文献１に記載の複室容器は、隔壁弱シール部と周縁強シール部との交点付近での強度を向上させることについて、一定の効果を得ることができる。
しかし、例えば、薬液の収容量が２０００ｍＬ程度の大型の複室容器では、上記交点付近での強度が依然として不十分である。このため、例えば、複室容器の側面からの落下に伴って隔壁弱シール部が意図せず開裂したり、一方の収容室を押圧して隔壁弱シール部を剥離させる際に、上記交点付近で周縁強シール部が開裂したりするおそれがある。また、複室容器の大型化に伴って、一方の収容室の押圧によって収容液を他方の収容室側へと誘導する際に隔壁弱シール部に負荷される液圧が、隔壁弱シール部全体に分散されることになり、隔壁弱シール部が開裂されにくくなるといった不具合や、開裂が不完全になるといった不具合も生じる。 However, the multi-chamber containers described in Patent Documents 1 to 4 and Non-Patent Document 1 can obtain a certain effect for improving the strength in the vicinity of the intersection between the partition weak seal portion and the peripheral strong seal portion. .
However, for example, in a large multi-chamber container having a chemical solution capacity of about 2000 mL, the strength near the intersection is still insufficient. For this reason, for example, when the partition weak seal part is unintentionally cleaved as it falls from the side surface of the multi-chamber container, or when one of the storage chambers is pressed to peel off the partition weak seal part, There is a risk that the peripheral strong seal portion may be cleaved. In addition, as the size of the multi-chamber container increases, the liquid pressure applied to the partition weak seal portion when guiding the storage liquid toward the other storage chamber by pressing one storage chamber is This causes a problem that the partition weak seal portion is difficult to be cleaved and a problem that the cleaving is incomplete.

一方、単に、補助強シール部の面積を大きくして、補強効果を増大させただけでは、複室容器の収容量が減少する。さらに、この場合には、複室容器を吊り下げたときに補助強シール部分で複室容器にひずみが生じ易くなり、収容液の容量の把握が困難になるといった別の不具合も生じる。
また、大容量の複室容器の一方の収容室内に、隔壁弱シール部の開裂に伴って開封される小袋が設けられている場合には、上記したように、隔壁弱シール部に負荷される液圧が隔壁弱シール部全体に分散することにより、上記小袋に対して液圧を集中して負荷できなくなって、小袋の開封が不完全になるおそれがある。 On the other hand, the capacity of the multi-chamber container is reduced simply by increasing the area of the auxiliary strong seal portion and increasing the reinforcing effect. Further, in this case, when the multi-chamber container is hung, another problem arises that the multi-chamber container is easily distorted at the auxiliary strong seal portion, and it is difficult to grasp the capacity of the stored liquid.
In addition, when a small bag is provided in one storage chamber of the large-capacity multi-chamber container to be opened along with the opening of the partition weak seal portion, as described above, the partition weak load portion is loaded. When the hydraulic pressure is dispersed throughout the partition weak seal portion, the hydraulic pressure cannot be concentrated and applied to the sachet, which may cause incomplete opening of the sachet.

そこで、本発明の目的は、たとえ収容量が大きい場合であっても、隔壁弱シール部や周縁強シール部の意図せぬ開裂を防止しつつ、隔壁弱シール部の易剥離性が維持された、取扱い性の良好な複室容器を提供することである。   Therefore, the object of the present invention is to maintain the easy separation of the partition weak seal portion while preventing unintentional cleavage of the partition weak seal portion and the peripheral strong seal portion even when the capacity is large. It is to provide a multi-chamber container with good handleability.

本発明の複室容器によれば、一対の側壁強シール部と隔壁弱シール部との間に設けられた補助強シール部によって、隔壁弱シール部と周縁強シール部との交点付近における強度を保持することができる。しかも、補助強シール部の周端縁（とりわけ、一方の収容室側の屈曲部、中間部および側端部）によって、一方の収容室を押圧したときの収容液の流れが規制されることから、隔壁弱シール部の幅方向（収容室の隣接方向と直交する方向）の中央部分（上記幅方向の中央３分の１領域）に、収容液の流れを集中的に案内することができる。すなわち、一方の収容室を押圧したときに隔壁弱シール部に対して加わる力を、隔壁弱シール部の上記幅方向外側よりも、上記幅方向内側の中央部分においてより大きくなるように調整することができる。   According to the multi-chamber container of the present invention, the auxiliary strong seal portion provided between the pair of side wall strong seal portions and the partition weak seal portion increases the strength in the vicinity of the intersection between the partition weak seal portion and the peripheral strong seal portion. Can be held. Moreover, the flow of the stored liquid when the one storage chamber is pressed is restricted by the peripheral edge of the auxiliary strong seal portion (particularly, the bent portion, the intermediate portion, and the side end portion on the one storage chamber side). The flow of the stored liquid can be intensively guided to the central portion (the central third region in the width direction) of the partition wall weak seal portion in the width direction (direction perpendicular to the adjacent direction of the storage chamber). That is, the force applied to the partition weak seal portion when one of the storage chambers is pressed is adjusted to be larger in the center portion in the width direction than in the width direction outside of the partition weak seal portion. Can do.

それゆえ、本発明によれば、たとえ収容量が大きい複室容器であっても、隔壁弱シール部や周縁強シール部の意図せぬ開裂を防止しつつ、隔壁弱シール部の開裂性を維持することができ、複室容器の取扱い性を良好なものとすることができる。   Therefore, according to the present invention, even in a multi-chamber container having a large capacity, the cleavability of the partition weak seal portion is maintained while preventing the unintentional cleavage of the partition weak seal portion and the peripheral strong seal portion. The handling property of the multi-chamber container can be improved.

図１は、本発明の複室容器の一実施形態を示す正面図であり、図２は、図１に示す複室容器の要部拡大平面図である。
図１および図２において、この複室容器１０は、収容液が封入される２つの収容室１１，１２と、周縁に設けられる周縁強シール部と、隣接する各収容室１１，１２を区画する隔壁弱シール部１３とを備えている。周縁強シール部は、２つの収容室１１，１２の隣接方向１４と直交する幅方向１５において互いに対向する、一対の側壁強シール部１６と、２つの収容室１１，１２の隣接方向１４において互いに対向する、一対の側壁強シール部１７とを備えており、平面視略矩形状に形成されている。また、隔壁弱シール部１３は、一対の側壁強シール部１６の間に設けられている。 FIG. 1 is a front view showing an embodiment of a multi-chamber container of the present invention, and FIG. 2 is an enlarged plan view of a main part of the multi-chamber container shown in FIG.
1 and 2, the multi-chamber container 10 divides the two storage chambers 11 and 12 in which the storage liquid is sealed, the peripheral strong seal portion provided at the periphery, and the adjacent storage chambers 11 and 12. And a partition weak seal portion 13. The peripheral strong seal portion is opposed to each other in the pair of side wall strong seal portions 16 and the adjacent direction 14 of the two storage chambers 11, 12 that face each other in the width direction 15 orthogonal to the adjacent direction 14 of the two storage chambers 11, 12. A pair of opposed strong side wall seal portions 17 are provided and are formed in a substantially rectangular shape in plan view. The partition weak seal portion 13 is provided between the pair of side wall strong seal portions 16.

また、複室容器１０は、各側壁強シール部１６の幅方向１５内側の端縁１８と、隔壁弱シール部１３の幅方向１５外側端部との間に、各側壁強シール部１６の幅方向１５内側の端縁１８から各収容室１１，１２の内部側へ張り出された一対の補助強シール部２０を備えている。
なお、補助強シール部２０は、隔壁弱シール部１３よりも後に形成することが好ましく、例えば、あらかじめ補助強シール部２０が形成される領域内へはみ出すように隔壁弱シール部１３を形成しておき、上記領域内にはみ出して形成された弱シール部分については、重ねて強い熱シールを施すことにより、強シール部分としてもよい。 Further, the multi-chamber container 10 has a width of each side wall strong seal portion 16 between an end edge 18 inside the width direction 15 of each side wall strong seal portion 16 and an outer end portion in the width direction 15 of the partition weak seal portion 13. A pair of auxiliary strong seal portions 20 projecting from the inner edge 18 in the direction 15 to the inner side of the storage chambers 11 and 12 are provided.
The auxiliary strong seal portion 20 is preferably formed after the partition weak seal portion 13. For example, the partition weak seal portion 13 is formed so as to protrude into a region where the auxiliary strong seal portion 20 is formed in advance. In addition, the weak seal portion formed so as to protrude into the region may be formed into a strong seal portion by applying a strong heat seal.

この場合、既に形成された隔壁シール部１３の一部に、補助強シール部２０が重ね合わされることになるが、弱シール部上に強い熱シールが施されることから、最終的に所期のシール強さを有する補助強シール部２０を得ることができる。
また、この場合、例えば、隔壁弱シール部１３の幅方向１５外側の端縁と、補助強シール部２０の後述する突出抑制部２１との間に、シール位置のずれに起因して未シール部が形成される、といった不具合が生じることを確実に防止できる。 In this case, the auxiliary strong seal portion 20 is superposed on a part of the partition seal portion 13 that has already been formed. However, since a strong heat seal is applied on the weak seal portion, the desired result is finally obtained. The auxiliary strong seal portion 20 having a seal strength of 5 can be obtained.
In this case, for example, an unsealed portion between the edge of the partition wall weak seal portion 13 on the outer side in the width direction 15 and a later-described protrusion suppressing portion 21 of the auxiliary strong seal portion 20 due to a shift in the seal position. It is possible to reliably prevent the occurrence of problems such as the formation of

なお、隔壁弱シール部の端縁１９は、補助強シール部２０に重ね合わされる領域だけでなく、例えば、未シール部４０内において、数ｍｍ程度突出されていてもよい。
側壁強シール部１６，１７および補助強シール部２０は、後述する隔壁弱シール部１３よりもシール強さが大きく、かつ、いずれかの収容室１１，１２を押圧して隔壁弱シール部１３を開裂させる際に、誤って側壁強シール部１６，１７および補助強シール部２０までも開裂されることがない程度のシール強さを有していることが必要である。側壁強シール部１６，１７および補助強シール部２０のシール強さは、これに限定されないが、それぞれ、好ましくは、２２Ｎ／１５ｍｍ以上であり、より好ましくは、３４Ｎ／１５ｍｍ以上である。 In addition, the edge 19 of the partition weak seal part may protrude about several millimeters in the unsealed part 40, for example, not only in the region superimposed on the auxiliary strong seal part 20.
The side wall strong seal portions 16 and 17 and the auxiliary strong seal portion 20 have a seal strength larger than that of the partition weak seal portion 13 described later, and press any one of the storage chambers 11 and 12 so that the partition weak seal portion 13 is pressed. When cleaving, it is necessary that the side wall strong seal portions 16 and 17 and the auxiliary strong seal portion 20 have a seal strength that does not cause the cleaving. The seal strength of the side wall strong seal portions 16 and 17 and the auxiliary strong seal portion 20 is not limited to this, but is preferably 22 N / 15 mm or more, and more preferably 34 N / 15 mm or more.

一方、隔壁弱シール部１３は、上記した側壁強シール部１６，１７および補助強シール部２０よりもシール強さが小さく、かつ、いずれかの収容室１１，１２を押圧して、隔壁弱シール部１３に対し収容液による液圧を負荷したときに、容易に開裂される程度のシール強さを有していること（すなわち、いわゆる易剥離性を備えていること）、および、複室容器の保存時や複室容器を誤って落下させた時などに、隔壁弱シール部１３の意図せぬ開裂が防止される程度のシール強さを有していることが必要である。隔壁弱シール部１３のシール強さは、これに限定されないが、好ましくは、２．０〜６．０Ｎ／１５ｍｍであり、より好ましくは、３．０〜５．０Ｎ／１５ｍｍである。   On the other hand, the partition weak seal portion 13 has a lower seal strength than the above-described side wall strong seal portions 16 and 17 and the auxiliary strong seal portion 20 and presses any one of the storage chambers 11 and 12 to weaken the partition weak seal. Having a sealing strength that can be easily cleaved when a liquid pressure is applied to the portion 13 by the stored liquid (that is, having a so-called easy peelability), and a multi-chamber container It is necessary to have a sealing strength that prevents unintentional tearing of the partition weak seal portion 13 when the container is stored or when the multi-chamber container is accidentally dropped. Although the sealing strength of the partition weak seal part 13 is not limited to this, Preferably it is 2.0-6.0N / 15mm, More preferably, it is 3.0-5.0N / 15mm.

なお、上記シール強さは、ＪＩＳ Ｚ ０２３７:2000「粘着テープ・粘着シート試験方法」の「１８０度引きはがし粘着力」の規定に準じて測定されたものである。このシール強さは、複室容器を形成するプラスチックフィルムについて、例えば、隔壁弱シール部１３を起点として、所定の幅（１５ｍｍ）で、かつ、その長さ方向で隔壁弱シール部１３と隔壁弱シール部１３に連なる未シール部分とが含まれるように切り取り、こうして得られた測定サンプルの一対のフィルム部分（隔壁弱シール部１３に連なる未シール部分）を、互いに１８０°の方向に２００ｍｍ／分の速度で引っ張って、隔壁弱シール部１３に剥離が生じたときの引張強さ（Ｎ／１５ｍｍ）として測定される。なお、側壁強シール部１６，１７および補助強シール部２０のシール強さについても、上記と同様にしてサンプルを作成し、測定すればよい。 The seal strength is measured in accordance with the provisions of “180 degree peeling adhesive strength” of JIS Z 0237 : 2000 “Testing method for adhesive tape and adhesive sheet”. The sealing strength of the plastic film forming the multi-chamber container is, for example, a predetermined width (15 mm) starting from the partition weak seal 13 and the partition weak seal 13 and the partition weak in the length direction. A pair of film portions (unsealed portions connected to the partition weak seal portion 13) of the measurement sample obtained in this manner were cut so as to include an unsealed portion connected to the seal portion 13 and 200 mm / min in a direction of 180 ° with respect to each other. It is measured as the tensile strength (N / 15 mm) when the partition weak seal portion 13 is peeled off. In addition, what is necessary is just to produce a sample similarly to the above and to measure also about the seal strength of the side wall strong seal parts 16 and 17 and the auxiliary | assistant strong seal part 20.

側壁強シール部１６の幅（幅方向１５の長さ）Ｗ3、隔壁弱シール部１３の幅（隣接方向１４の長さ）Ｗ4および補助強シール部２０の幅Ｗ5は、いずれも、複室容器の大きさ（収容量）や、隔壁弱シール部１３、側壁強シール部１６および補助強シール部２０のシール強さなどに応じて、適宜設定される。それゆえ、特に限定されないが、例えば、複室容器の収容量が全体で１〜２Ｌ程度の、比較的大容量の複室容器の場合に、側壁強シール部１６の幅Ｗ3および補助強シール部２０の幅Ｗ5は、ともに、好ましくは、５〜１５ｍｍであり、より好ましくは、７〜１０ｍｍである。また、収容量が全体で１〜２Ｌ程度の複室容器の場合に、隔壁弱シール部１３の幅Ｗ4は、好ましくは、１０〜２５ｍｍであり、より好ましくは、１０〜２０ｍｍである。 The width of the side wall strong seal portion 16 (length in the width direction 15) W 3 , the width of the partition weak seal portion 13 (length in the adjacent direction 14) W 4 and the width W 5 of the auxiliary strong seal portion 20 are all: It is appropriately set according to the size (accommodation amount) of the multi-chamber container, the sealing strength of the partition weak seal portion 13, the side wall strong seal portion 16 and the auxiliary strong seal portion 20. Therefore, although not particularly limited, for example, in the case of a relatively large-capacity multi-chamber container in which the total capacity of the multi-chamber container is about 1 to 2 L, the width W 3 of the side wall strong seal portion 16 and the auxiliary strong seal The width W 5 of the part 20 is preferably 5 to 15 mm, more preferably 7 to 10 mm. In the case of a multi-chamber container having a total capacity of about 1 to 2 L, the width W 4 of the partition weak seal portion 13 is preferably 10 to 25 mm, more preferably 10 to 20 mm.

It is formed and is linear.

補助強シール部２０周端縁の屈曲部２２は、図２中の曲線部ｂ−ｃで示されるように、補助強シール部２０周端縁の突出抑制部２１と中間部２４との間で、一方の収容室１１の内部側に対して凸状に湾曲している。より具体的に、屈曲部２２は、凸状の湾曲部分（屈曲部２２）よりも補助強シール部２０の内部側に位置する任意の点ａを中心として、所定半径の円周の一部（円弧）となっている。   The bent portion 22 at the peripheral edge of the auxiliary strong seal portion 20 is between the protrusion suppressing portion 21 and the intermediate portion 24 at the peripheral edge of the auxiliary strong seal portion 20 as indicated by a curved line bc in FIG. , Is curved in a convex shape with respect to the inner side of the one storage chamber 11. More specifically, the bent portion 22 is a part of the circumference of a predetermined radius (centered at an arbitrary point a located on the inner side of the auxiliary strong seal portion 20 with respect to the convex curved portion (bent portion 22)). Arc).

なお、屈曲部２２は、突出抑制部２１の一方の収容室１１側の端部から連続し、側壁強シール部１６へ向かって、かつ、隔壁弱シール部１３に対し他方の収容室１２側とは反対の側へ傾斜して屈曲していること以外は、特に限定されるものではない。それゆえ、必ずしも所定半径の円弧でなくてもよく、単に、補助強シール部２０周端縁の突出抑制部２１と中間部２４との間で、一方の収容室１１の内部側に対して凸状に湾曲していてもよい。   The bent portion 22 is continuous from the end portion on the one storage chamber 11 side of the protrusion suppressing portion 21, toward the side wall strong seal portion 16, and on the other storage chamber 12 side with respect to the partition weak seal portion 13. Is not particularly limited except that it is inclined and bent to the opposite side. Therefore, it does not necessarily have to be an arc having a predetermined radius, and is simply convex between the protrusion suppressing portion 21 and the intermediate portion 24 at the peripheral edge of the auxiliary strong seal portion 20 with respect to the inner side of the one storage chamber 11. May be curved.

補助強シール部２０周端縁の側端部２３は、図２中の曲線部ｅ−ｆで示されるように、一方の収容室１１における側壁強シール部１６の端縁１８と、補助強シール部２０周端縁の中間部２４との間で、一方の収容室１１の内部側に対して凹状に湾曲している。より具体的に、側端部２３は、凹状の湾曲部分（側端部２３）よりも補助強シール部２０の外部側（一方の収容室１１側）に位置する任意の点ｄを中心として、所定半径の円周の一部（円弧）となっている。   The side edge 23 of the peripheral edge of the auxiliary strong seal portion 20 is connected to the edge 18 of the side wall strong seal portion 16 in the one storage chamber 11 and the auxiliary strong seal, as indicated by a curved line ef in FIG. Between the intermediate part 24 of the peripheral edge of the part 20, it is curved in a concave shape with respect to the inner side of the one storage chamber 11. More specifically, the side end portion 23 is centered on an arbitrary point d positioned on the outer side (one storage chamber 11 side) of the auxiliary strong seal portion 20 with respect to the concave curved portion (side end portion 23). It is a part of the circumference (arc) of a predetermined radius.

なお、側端部２３は、一方の収容室１１における側壁強シール部１６の端縁１８から連続し、幅方向１５内側へ向かって、かつ、隔壁弱シール部１３に対し他方の収容室１２側へ傾斜していること以外は、特に限定されるものではない。それゆえ、必ずしも所定半径の円弧でなくてもよく、単に、側壁強シール部１６の端縁１８と補助強シール部２０周端縁の中間部２４との間で、一方の収容室１１の内部側に対して凹状に湾曲していてもよい。   The side end portion 23 is continuous from the end edge 18 of the side wall strong seal portion 16 in one storage chamber 11, toward the inner side in the width direction 15, and on the other storage chamber 12 side with respect to the partition weak seal portion 13. There is no particular limitation except that it is inclined to the right. Therefore, it does not necessarily have to be a circular arc with a predetermined radius, and is simply between the end edge 18 of the side wall strong seal part 16 and the intermediate part 24 of the peripheral edge of the auxiliary strong seal part 20 inside the one storage chamber 11. It may be concavely curved with respect to the side.

補助強シール部２０周端縁の中間部２４は、図２中の直線部ｃ−ｆで示されるように、補助強シール部２０周端縁の屈曲部２２と側端部２３との間において、屈曲部２２および側端部２３のそれぞれと連続して形成されており、直線状となっている。
図１および図２に示す複室容器１０において、各補助強シール部２０周端縁の中間部２４に沿う延長線２５と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点２７は、それぞれ、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央３分の１領域２８内に存在している。 The intermediate portion 24 of the peripheral edge of the auxiliary strong seal portion 20 is between the bent portion 22 and the side end portion 23 of the peripheral edge of the auxiliary strong seal portion 20 as indicated by a straight line portion cf in FIG. Each of the bent portion 22 and the side end portion 23 is formed continuously and has a linear shape.
In the multi-chamber container 10 shown in FIG. 1 and FIG. 2, an extension line 25 along the intermediate portion 24 of the peripheral edge of each auxiliary strong seal portion 20, an end edge 26 on the one storage chamber 11 side of the partition weak seal portion 13, The crossing points 27 are present in the central third region 28 in the width direction 15 between the end edges 18 of the pair of side wall strong seal portions 16.

上述したとおり、各補助強シール部２０の周端縁が、一方の収容室１１側において、上記の屈曲部２２と側端部２３と中間部２４とを備えており、しかも、中間部２４に沿う延長線２５と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点２７が、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央３分の１領域２８内に存在していることから、一方の収容室１１を押圧したときの収容液の流れを、隔壁弱シール部１３の幅方向１５中央部分に集中して案内することができ、一方の収容室１１を押圧したときに隔壁弱シール部１３に対して加わる力を、隔壁弱シール部１３の幅方向１５外側よりも、幅方向１５内側の中央部分においてより大きくなるように調整することができる。また、その結果、たとえ複室容器１０が大型化した場合であっても、使用時の隔壁弱シール部１３の開裂を確実に達成させることができる。   As described above, the peripheral edge of each auxiliary strong seal portion 20 includes the bent portion 22, the side end portion 23, and the intermediate portion 24 on the side of the one storage chamber 11. The intersection 27 of the extended line 25 along the edge 26 on the side of the one storage chamber 11 of the partition weak seal portion 13 is the center third in the width direction 15 between the edges 18 of the pair of side wall strong seal portions 16. Since it exists in the area | region 28, the flow of the accommodation liquid when pressing one storage chamber 11 can be concentrated and guided to the center part of the width direction 15 of the partition weak seal part 13, and one side can be guided. The force applied to the partition weak seal portion 13 when the storage chamber 11 is pressed can be adjusted to be larger at the center portion inside the width direction 15 than outside the width direction 15 of the partition weak seal portion 13. it can. As a result, even when the multi-chamber container 10 is enlarged, it is possible to reliably achieve the cleavage of the partition weak seal portion 13 during use.

各補助強シール部２０周端縁の中間部２４に沿う延長線２５と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点２７は、上記範囲の中でも特に、それぞれ、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央１０分の３領域内に存在していることが好ましく、中央１０分の２領域内に存在していることがより好ましい。
図１および図２に示す複室容器１０において、各補助強シール部２０についての幅方向１５の長さ（各側壁強シール部１６の端縁１８と、各補助強シール部２０周端縁の突出抑制部２１との間の幅方向１５の長さ）Ｄ1は、一対の側壁強シール部１６の端縁１８間での幅（幅方向１５の長さ）Ｗ1に対して、下記式（１）で示されるように形成されている。
Ｗ1／２０＜Ｄ1＜Ｗ1／１０ ……（１） The intersection 27 of the extension line 25 along the intermediate portion 24 of the peripheral edge of each auxiliary strong seal portion 20 and the end edge 26 on the one storage chamber 11 side of the partition weak seal portion 13 is particularly in the above range, respectively. It is preferable to exist in the central three-tenth region in the width direction 15 between the end edges 18 of the pair of side wall strong seal portions 16, and it is more preferable to exist in the central two-tenth region.
In the multi-chamber container 10 shown in FIGS. 1 and 2, the length in the width direction 15 of each auxiliary strong seal portion 20 (the edge 18 of each side strong seal portion 16 and the peripheral edge of each auxiliary strong seal portion 20). length) D 1 in the width direction 15 between the spur suppression unit 21, the length of the width (the width direction 15 of between edges 18 of the pair of side walls strong seal part 16) with respect to W 1, the following formula It is formed as shown in (1).
W 1/20 <D 1 < W 1/10 ...... (1)

すなわち、各補助強シール部２０についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1は、一対の側壁強シール部１６の端縁１８間の幅Ｗ1に対して、その２０分の１よりも大きく、かつ、１０分の１よりも小さくなるように形成されている。
このように、各補助強シール部２０についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1が、一対の側壁強シール部の端縁１８間の幅Ｗ1の２０分の１よりも大きく形成されることにより、一方の収容室１１を押圧したときに一方の収容室１１内の収容液が隔壁弱シール部１３の幅方向１５中央部に案内される作用を、十分に発揮できるようになる。一方、各補助強シール部２０についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1が、一対の側壁強シール部１６の端縁１８間の幅Ｗ1の１０分の１よりも小さく形成されることにより、複室容器１０を吊り下げたときに複室容器１０に歪みが生じて、容器表面に設けられた内容量測定用の目盛りが見づらくなるといった不具合が生じることを防止できる。また、補助強シール部２０が巨大化することに伴う複室容器１０の収容量の減少を抑制することができる。 That is, the length (between edges 18 projecting suppressing portion 21) D 1 in the width direction 15 of each auxiliary strong seal part 20, the width W 1 between the edges 18 of the pair of side walls strong seal portion 16 It is formed so as to be larger than 1/20 and smaller than 1/10.
Thus, the length (between edges 18 projecting suppressing portion 21) D 1 in the width direction 15 of each auxiliary strong seal portion 20, 20 of the width W 1 between the pair of side walls strong seal portion of the end edge 18 By being formed to be larger than one part, when the one storage chamber 11 is pressed, the stored liquid in the one storage chamber 11 is guided to the central portion in the width direction 15 of the partition weak seal portion 13. It will be able to fully demonstrate. On the other hand, the length (between edges 18 projecting suppressing portion 21) D 1 in the width direction 15 of each auxiliary strong seal portion 20, 10 of the width W 1 between the edges 18 of the pair of side walls strong seal portion 16 When the multi-chamber container 10 is suspended, the multi-chamber container 10 is distorted and the internal volume measurement scale provided on the container surface is difficult to see. Can be prevented. Moreover, the reduction | decrease of the accommodation capacity of the multi-chamber container 10 accompanying the auxiliary strong seal part 20 enlarging can be suppressed.

図１および図２に示す複室容器１０において、他方の収容室１２側における補助強シール部２０の周端縁の形状は、特に限定されないが、例えば、隔壁弱シール部１３の隣接方向１４の中心線を対称軸として、一方の収容室１１側における補助強シール部２０周端縁の形状（すなわち、突出抑制部２１の一部と、屈曲部２２、中間部２４および側端部２３の形状）が対称に現れるように形成されていてもよい。このように、補助強シール部２０の周端縁の形状が、一方の収容室１１側と他方の収容室１２側とで対称に現れている場合において、隔壁弱シール部１３の開裂は、一方の収容室１１を押圧することによって達成されるだけでなく、他方の収容室１２を押圧することによっても達成することができる。   In the multi-chamber container 10 shown in FIGS. 1 and 2, the shape of the peripheral edge of the auxiliary strong seal portion 20 on the other storage chamber 12 side is not particularly limited, but for example, in the adjacent direction 14 of the partition weak seal portion 13. The shape of the peripheral edge of the auxiliary strong seal portion 20 on the one storage chamber 11 side (that is, the shape of a part of the protrusion suppressing portion 21, the bent portion 22, the intermediate portion 24, and the side end portion 23 with the center line as the axis of symmetry) ) May appear symmetrically. As described above, when the shape of the peripheral edge of the auxiliary strong seal portion 20 appears symmetrically on the one storage chamber 11 side and the other storage chamber 12 side, This can be achieved not only by pressing the other storage chamber 11 but also by pressing the other storage chamber 12.

なお、側端部３０は、一方の収容室１１における側壁強シール部１６の端縁１８から連続し、幅方向１５内側へ向かって、かつ、隔壁弱シール部１３に対し他方の収容室１２側へ傾斜していること以外は、特に限定されるものではない。それゆえ、必ずしも所定半径の円弧でなくてもよく、単に、側壁強シール部１６の端縁１８と補助強シール部２９周端縁の中間部３１との間で、一方の収容室１１の内部側に対して凹状に湾曲していてもよい。   The side end portion 30 is continuous from the end edge 18 of the side wall strong seal portion 16 in one storage chamber 11, toward the inner side in the width direction 15, and on the other storage chamber 12 side with respect to the partition weak seal portion 13. There is no particular limitation except that it is inclined to the right. Therefore, it does not necessarily have to be an arc having a predetermined radius, and is simply the inside of one storage chamber 11 between the edge 18 of the side wall strong seal portion 16 and the intermediate portion 31 of the peripheral edge of the auxiliary strong seal portion 29. It may be concavely curved with respect to the side.

また、補助強シール部２９周端縁の中間部３１は、図３中の点ｃで示されるように、屈曲部２２と側端部３０との間において変曲点をなしている。それゆえ、図３に示す設計変更例において、各補助強シール部２９周端縁の中間部３１に沿う延長線は、各中間部３１における接線３２である。
図３に示す設計変更例において、各補助強シール部２９周端縁の中間部３１における接線３２と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点（図示せず）は、それぞれ、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央３分の１領域内に存在している。 Further, the intermediate portion 31 at the peripheral edge of the auxiliary strong seal portion 29 forms an inflection point between the bent portion 22 and the side end portion 30, as indicated by a point c in FIG. Therefore, in the design modification example shown in FIG. 3, the extension line along the intermediate portion 31 of the peripheral edge of each auxiliary strong seal portion 29 is a tangent line 32 in each intermediate portion 31.
In the design change example shown in FIG. 3, the intersection (not shown) between the tangent line 32 in the intermediate portion 31 of the peripheral edge of each auxiliary strong seal portion 29 and the end edge 26 on the one storage chamber 11 side of the partition weak seal portion 13. ) Exist in the central third region in the width direction 15 between the end edges 18 of the pair of side wall strong seal portions 16.

各補助強シール部２９周端縁の中間部３１における接線３２と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点は、上記範囲の中でも特に、それぞれ、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央１０分の３領域内に存在していることが好ましく、中央１０分の２領域内に存在していることがより好ましい。
図３に示す設計変更例においても、各補助強シール部２９の周端縁が、一方の収容室１１側において、上記の屈曲部２２と側端部３０と中間部３１とを備えており、しかも、中間部（変曲点）３１に沿う接線（延長線）３２と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点が、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央３分の１領域内に存在していることから、一方の収容室１１を押圧したときの収容液の流れを、隔壁弱シール部１３の幅方向１５中央部分に集中して案内することができ、一方の収容室１１を押圧したときに隔壁弱シール部１３に対して加わる力を、隔壁弱シール部１３の幅方向１５外側よりも、幅方向１５内側の中央部分においてより大きくなるように調整することができる。また、その結果、たとえ複室容器が大型化した場合であっても、使用時の隔壁弱シール部１３の開裂を確実に達成させることができる。 The intersection between the tangent line 32 in the intermediate portion 31 of the peripheral edge of each auxiliary strong seal portion 29 and the end edge 26 on the one storage chamber 11 side of the partition weak seal portion 13 is a pair of side walls, particularly in the above range. It is preferable that it exists in the center 3/10 area | region of the width direction 15 between the edge 18 of the strong seal | sticker part 16, and it exists more preferably in the center 2/10 area | region.
Also in the design change example shown in FIG. 3, the peripheral edge of each auxiliary strong seal portion 29 is provided with the bent portion 22, the side end portion 30, and the intermediate portion 31 on the one storage chamber 11 side, Moreover, the intersection of the tangent line (extension line) 32 along the intermediate portion (inflection point) 31 and the edge 26 on the one chamber 11 side of the partition weak seal portion 13 is the end of the pair of side wall strong seal portions 16. Since it exists in the center 1/3 area | region of the width direction 15 between the edges 18, the flow of the accommodation liquid when pressing the one accommodation chamber 11 is made into the center part of the width direction 15 of the partition weak seal part 13 The force applied to the partition weak seal portion 13 when one of the storage chambers 11 is pressed can be guided to the inner side in the width direction 15 than the outer side in the width direction 15 of the partition weak seal portion 13. It can be adjusted to be larger in the central part. As a result, even when the multi-chamber container is enlarged, it is possible to reliably achieve the cleavage of the partition weak seal portion 13 during use.

また、図３に示す設計変更例においても、各補助強シール部２９についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1が、一対の側壁強シール部１６の端縁１８間の幅Ｗ1の２０分の１よりも大きく形成されることにより、一方の収容室１１を押圧したときに一方の収容室１１内の収容液が隔壁弱シール部１３の幅方向１５中央部に案内される作用を、十分に発揮できるようになる。一方、各補助強シール部２９についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1が、一対の側壁強シール部１６の端縁１８間の幅Ｗ1の１０分の１よりも小さく形成されることにより、複室容器を吊り下げたときに複室容器に歪みが生じたり、補助強シール部２９の巨大化に伴って複室容器の収容量が減少したりすることを抑制できる。 Also in the design modification example shown in FIG. 3, the length in the width direction 15 (between the end edge 18 and the protrusion suppressing portion 21) D 1 for each auxiliary strong seal portion 29 is the end of the pair of side wall strong seal portions 16. By being formed to be larger than 1/20 of the width W 1 between the edges 18, when the one storage chamber 11 is pressed, the stored liquid in the one storage chamber 11 becomes 15 in the width direction 15 of the partition weak seal portion 13. The action guided to the central part can be sufficiently exhibited. On the other hand, the length (between edges 18 projecting suppressing portion 21) D 1 in the width direction 15 of each auxiliary strong seal portion 29, 10 of the width W 1 between the edges 18 of the pair of side walls strong seal portion 16 When the multi-chamber container is suspended, the multi-chamber container is distorted or the capacity of the multi-chamber container is reduced as the auxiliary strong seal portion 29 is enlarged. Can be suppressed.

図３に示す設計変更例において、他方の収容室１２側における補助強シール部２９の周端縁の形状は、特に限定されないが、例えば、隔壁弱シール部１３の隣接方向１４の中心線を対称軸として、一方の収容室１１側における補助強シール部２９の周端縁の形状（すなわち、突出抑制部２１の一部と、屈曲部２２、中間部３１および側端部３０の形状）が対称に現れるように形成されていてもよい。このように、補助強シール部２９の周端縁の形状が、一方の収容室１１側と他方の収容室１２側とで対称に現れている場合において、隔壁弱シール部１３の開裂は、一方の収容室１１を押圧することによって達成されるだけでなく、他方の収容室１２を押圧することによっても達成することができる。   In the design change example shown in FIG. 3, the shape of the peripheral edge of the auxiliary strong seal portion 29 on the other storage chamber 12 side is not particularly limited. For example, the center line in the adjacent direction 14 of the partition weak seal portion 13 is symmetric. As a shaft, the shape of the peripheral edge of the auxiliary strong seal portion 29 on the side of one of the storage chambers 11 (that is, the shape of the protrusion suppressing portion 21 and the bent portion 22, the intermediate portion 31, and the side end portion 30) is symmetrical. It may be formed to appear in As described above, when the shape of the peripheral edge of the auxiliary strong seal portion 29 appears symmetrically on the one storage chamber 11 side and the other storage chamber 12 side, the cleavage of the partition weak seal portion 13 is This can be achieved not only by pressing the other storage chamber 11 but also by pressing the other storage chamber 12.

図４は、図１および図２に示す複室容器の他の設計変更例を示す要部拡大平面図である。
図４に示す設計変更例において、補助強シール部３３の周端縁は、下記の部分を含んでいる。
・隔壁弱シール部１３の幅方向１５外側の端縁１９にそれぞれ当接して、補助強シール部３３の幅方向１５内側への突出を抑制する突出抑制部２１（図４中の直線部ｂ−ｂ’）
・突出抑制部２１の一方の収容室１１側の端部から連続し、側壁強シール部１６へ向かって、かつ、隔壁弱シール部１３に対し他方の収容室１２側とは反対の側へ傾斜して屈曲する屈曲部２２（図４中の曲線部ｂ−ｃ）
・一方の収容室１１における側壁強シール部１６の幅方向１５内側の端縁１８から、幅方向１５内側へ向かって、かつ、隔壁弱シール部１３に対し他方の収容室１２側へ傾斜して延びる側端部３４（図４中の直線部α−ｃ）
・屈曲部２２と側端部３４との間で、屈曲部２２および側端部３４のそれぞれと連続する中間部３５（図４中の点ｃ）
なお、図４に示す設計変更例と、図１および図２に示す複室容器１０とは、補助強シール部の形状が異なること以外は、同様の構造を備えている。 FIG. 4 is an enlarged plan view of a main part showing another example of a design change of the multi-chamber container shown in FIGS. 1 and 2.
In the design change example shown in FIG. 4, the peripheral edge of the auxiliary strong seal portion 33 includes the following portions.
A protrusion restraining portion 21 (straight line portion b− in FIG. 4) that abuts against the edge 19 on the outer side of the width direction 15 of the partition weak seal portion 13 to suppress the auxiliary strong seal portion 33 from projecting inward in the width direction 15. b ')
-It continues from the edge part by the side of one storage chamber 11 of the protrusion suppression part 21, and it inclines toward the side wall strong seal part 16 and the opposite side to the other storage chamber 12 side with respect to the partition weak seal part 13 Bent part 22 (curved part bc in FIG. 4)
-Inclination from the edge 18 inside the width direction 15 of the side wall strong seal portion 16 in one storage chamber 11 toward the inside in the width direction 15 and toward the other storage chamber 12 with respect to the partition weak seal portion 13 Extending side end 34 (straight line portion α-c in FIG. 4)
-Between the bent part 22 and the side end part 34, the intermediate part 35 (point c in FIG. 4) which continues with each of the bent part 22 and the side end part 34
The design change example shown in FIG. 4 and the multi-chamber container 10 shown in FIGS. 1 and 2 have the same structure except that the shape of the auxiliary strong seal portion is different.

図４に示す設計変更例において、補助強シール部３３周端縁の突出抑制部２１は、図１および図２に示す補助強シール部２０の突出抑制部２１と同様である。すなわち、図４中の直線部ｂ−ｂ’で示されるように、補助強シール部３３周端縁の屈曲部２２と、補助強シール部３３の他方の収容室１２側における周端縁（図４中の曲線部ｂ’−α’）との間で、屈曲部２２および他方の収容室１２側における周端縁とのそれぞれと連続して形成されており、直線状となっている。   In the design change example shown in FIG. 4, the protrusion suppressing portion 21 at the peripheral edge of the auxiliary strong seal portion 33 is the same as the protrusion suppressing portion 21 of the auxiliary strong seal portion 20 shown in FIGS. 1 and 2. That is, as shown by a straight line part bb ′ in FIG. 4, the bent portion 22 of the peripheral edge of the auxiliary strong seal portion 33 and the peripheral edge of the auxiliary strong seal portion 33 on the other storage chamber 12 side (see FIG. 4 and the curved portion b′-α ′) are formed continuously with the bent portion 22 and the peripheral edge on the other storage chamber 12 side, and are linear.

補助強シール部３３周端縁の屈曲部２２は、図１および図２に示す補助強シール部２０の屈曲部２２と同様である。すなわち、図４中の曲線部ｂ−ｃで示されるように、補助強シール部３３周端縁の突出抑制部２１と中間部３５との間で、一方の収容室１１の内部側に対して凸状に湾曲している。より具体的に、屈曲部２２は、凸状の湾曲部分（屈曲部２２）よりも補助強シール部３３の内部側に位置する任意の点ａを中心として、所定半径の円周の一部（円弧）となっている。   The bent portion 22 at the peripheral edge of the auxiliary strong seal portion 33 is the same as the bent portion 22 of the auxiliary strong seal portion 20 shown in FIGS. That is, as indicated by a curved line part bc in FIG. 4, between the protrusion suppressing part 21 and the intermediate part 35 on the peripheral edge of the auxiliary strong seal part 33, with respect to the inner side of the one storage chamber 11. Curved in a convex shape. More specifically, the bent portion 22 is a part of the circumference of a predetermined radius (centered at an arbitrary point a located on the inner side of the auxiliary strong seal portion 33 with respect to the convex curved portion (bent portion 22)). Arc).

補助強シール部３３周端縁の側端部３４は、図４中の直線部α−ｃで示されるように、一方の収容室１１における側壁強シール部１６の端縁１８と、補助強シール部３３周端縁の中間部３５との間で、直線状に形成されている。
また、補助強シール部３３周端縁の中間部３５は、図４中の点ｃで示されるように、屈曲部２２と側端部３４との間において屈曲点をなしている。それゆえ、図４に示す設計変更例において、各補助強シール部３３端縁の中間部３５に沿う延長線は、各中間部３５における接線３６である。 The side edge 34 of the peripheral edge of the auxiliary strong seal portion 33 is connected to the edge 18 of the side wall strong seal portion 16 in one storage chamber 11 and the auxiliary strong seal, as indicated by a straight line portion α-c in FIG. It is formed in a straight line with the intermediate portion 35 at the peripheral edge of the portion 33.
Further, the intermediate portion 35 at the peripheral edge of the auxiliary strong seal portion 33 forms a bending point between the bent portion 22 and the side end portion 34 as indicated by a point c in FIG. Therefore, in the design modification example shown in FIG. 4, the extension line along the intermediate portion 35 of the end edge of each auxiliary strong seal portion 33 is a tangent line 36 in each intermediate portion 35.

図４に示す設計変更例において、各補助強シール部３３周端縁の中間部３５における接線３６と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点（図示せず）は、それぞれ、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央３分の１領域内に存在している。
各補助強シール部３３周端縁の中間部３５における接線３６と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点は、上記範囲の中でも特に、それぞれ、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央１０分の３領域内に存在していることが好ましく、中央１０分の２領域内に存在していることがより好ましい。 In the design change example shown in FIG. 4, the intersection (not shown) between the tangent line 36 in the intermediate portion 35 of the peripheral edge of each auxiliary strong seal portion 33 and the end edge 26 on the one storage chamber 11 side of the partition weak seal portion 13. ) Exist in the central third region in the width direction 15 between the end edges 18 of the pair of side wall strong seal portions 16.
The intersection of the tangent line 36 in the intermediate portion 35 of the peripheral edge of each auxiliary strong seal portion 33 and the end edge 26 on the one storage chamber 11 side of the partition weak seal portion 13 is a pair of side walls, particularly in the above range. It is preferable that it exists in the center 3/10 area | region of the width direction 15 between the edge 18 of the strong seal | sticker part 16, and it exists more preferably in the center 2/10 area | region.

図４に示す設計変更例においても、各補助強シール部３３の周端縁が、一方の収容室１１側において、上記の屈曲部２２と側端部３４と中間部３５とを備えており、しかも、中間部（変曲点）３５に沿う接線（延長線）３６と、隔壁弱シール部１３の一方の収容室１１側の端縁２６との交点が、一対の側壁強シール部１６の端縁１８間における幅方向１５の中央３分の１領域内に存在していることから、一方の収容室１１を押圧したときの収容液の流れを、隔壁弱シール部１３の幅方向１５中央部分に集中して案内することができ、一方の収容室１１を押圧したときに隔壁弱シール部１３に対して加わる力を、隔壁弱シール部１３の幅方向１５外側よりも、幅方向１５内側の中央部分においてより大きくなるように調整することができる。また、その結果、たとえ複室容器が大型化した場合であっても、使用時の隔壁弱シール部１３の開裂を確実に達成させることができる。   Also in the design change example shown in FIG. 4, the peripheral edge of each auxiliary strong seal portion 33 includes the bent portion 22, the side end portion 34, and the intermediate portion 35 on the one storage chamber 11 side, In addition, the intersection of the tangent (extension line) 36 along the intermediate portion (inflection point) 35 and the edge 26 on the one chamber 11 side of the partition weak seal portion 13 is the end of the pair of side wall strong seal portions 16. Since it exists in the center 1/3 area | region of the width direction 15 between the edges 18, the flow of the accommodation liquid when pressing the one accommodation chamber 11 is made into the center part of the width direction 15 of the partition weak seal part 13 The force applied to the partition weak seal portion 13 when one of the storage chambers 11 is pressed can be guided to the inner side in the width direction 15 than the outer side in the width direction 15 of the partition weak seal portion 13. It can be adjusted to be larger in the central part. As a result, even when the multi-chamber container is enlarged, it is possible to reliably achieve the cleavage of the partition weak seal portion 13 during use.

また、図４に示す設計変更例においても、各補助強シール部３３についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1が、一対の側壁強シール部１６の端縁１８間の幅Ｗ1の２０分の１よりも大きく形成されることにより、一方の収容室１１を押圧したときに一方の収容室１１内の収容液が隔壁弱シール部１３の幅方向１５中央部に案内される作用を、十分に発揮できるようになる。一方、各補助強シール部３３についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1が、一対の側壁強シール部１６の端縁１８間の幅Ｗ1の１０分の１よりも小さく形成されることにより、複室容器を吊り下げたときに複室容器に歪みが生じたり、補助強シール部３３の巨大化に伴って複室容器の収容量が減少したりすることを抑制できる。 Also, in the design modification example shown in FIG. 4, the length in the width direction 15 (between the end edge 18 and the protrusion suppressing portion 21) D 1 for each auxiliary strong seal portion 33 is the end of the pair of side wall strong seal portions 16. By being formed to be larger than 1/20 of the width W 1 between the edges 18, when the one storage chamber 11 is pressed, the stored liquid in the one storage chamber 11 becomes 15 in the width direction 15 of the partition weak seal portion 13. The action guided to the central part can be sufficiently exhibited. On the other hand, the length (between edges 18 projecting suppressing portion 21) D 1 in the width direction 15 of each auxiliary strong seal portion 33, 10 of the width W 1 between the edges 18 of the pair of side walls strong seal portion 16 When the multi-chamber container is suspended, the multi-chamber container is distorted, or the capacity of the multi-chamber container is reduced as the auxiliary strong seal portion 33 is enlarged. Can be suppressed.

図４に示す設計変更例において、他方の収容室１２側における補助強シール部３３の周端縁の形状は、特に限定されないが、例えば、隔壁弱シール部１３の隣接方向１４の中心線を対称軸として、一方の収容室１１側における補助強シール部３３の周端縁の形状（すなわち、突出抑制部２１の一部と、屈曲部２２、中間部３５および側端部３４の形状）が対称に現れるように形成されていてもよい。このように、補助強シール部３３の周端縁の形状が、一方の収容室１１側と他方の収容室１２側とで対称に現れている場合において、隔壁弱シール部１３の開裂は、一方の収容室１１を押圧することによって達成されるだけでなく、他方の収容室１２を押圧することによっても達成することができる。   In the design change example shown in FIG. 4, the shape of the peripheral edge of the auxiliary strong seal portion 33 on the other storage chamber 12 side is not particularly limited. For example, the center line in the adjacent direction 14 of the partition weak seal portion 13 is symmetric. As a shaft, the shape of the peripheral edge of the auxiliary strong seal portion 33 on the side of one of the storage chambers 11 (that is, the shape of a part of the protrusion suppressing portion 21, the bent portion 22, the intermediate portion 35, and the side end portion 34) is symmetrical. It may be formed to appear in As described above, when the shape of the peripheral edge of the auxiliary strong seal portion 33 appears symmetrically on the one storage chamber 11 side and the other storage chamber 12 side, the cleavage of the partition weak seal portion 13 is This can be achieved not only by pressing the other storage chamber 11 but also by pressing the other storage chamber 12.

図５は、本発明の複室容器の一実施形態を示す正面図である。
図５において、この複室容器３７は、他方の収容室１２に、隔壁弱シール部１３の開裂に伴って開封される小袋３８を備えている。この小袋３８は、隔壁弱シール部１３の開裂に伴って開封される開封部３９が、隔壁弱シール部１３における幅方向１５内側の中央部と対向して固定されている。 FIG. 5 is a front view showing an embodiment of the multi-chamber container of the present invention.
In FIG. 5, the multi-chamber container 37 includes a small bag 38 opened in the other storage chamber 12 when the partition weak seal portion 13 is cleaved. In this sachet 38, an unsealing portion 39 that is opened when the partition weak seal portion 13 is opened is fixed so as to face the central portion inside the width direction 15 in the partition weak seal portion 13.

また、図５において、複室容器３７は、他方の収容室１２内に小袋３８を備えていること以外は、図１および図２に示す実施形態に係る複室容器１０と同様である。
図５に示す複室容器によれば、図１および図２に示す実施形態に係る複室容器１０と同様に、一方の収容室１１を押圧したときの収容液の流れを、隔壁弱シール部１３の幅方向１５中央部分に集中して案内することができることから、一方の収容室１１の開裂に伴う小袋３８の開封部３９での開裂を、確実に達成することができる。 Further, in FIG. 5, the multi-chamber container 37 is the same as the multi-chamber container 10 according to the embodiment shown in FIGS. 1 and 2 except that a sachet 38 is provided in the other storage chamber 12.
According to the multi-chamber container shown in FIG. 5, as in the multi-chamber container 10 according to the embodiment shown in FIGS. 1 and 2, the flow of the contained liquid when pressing one of the containing chambers 11 13 can be concentrated and guided in the central portion of the width direction 15 of the 13, so that it is possible to reliably achieve the tearing at the opening portion 39 of the pouch 38 accompanying the tearing of the one storage chamber 11.

図１〜図５に示す実施形態および設計変更例において、補助強シール部２０，２９，３３は、側壁強シール部１６の端縁１８における隣接方向１４の長さＬ1が、各補助強シール部２０，２９，３３についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1に対して、下記式（２）で示されるように形成されている。
Ｄ1≦Ｌ1≦３Ｄ1 ……（２）
すなわち、側壁強シール部１６の端縁１８における隣接方向１４の長さＬ1は、補助強シール部２０，２９，３３についての幅方向１５の長さ（端縁１８−突出抑制部２１間）Ｄ1と同等、または、その３倍以下となるように形成されている。これにより、補助強シール部を設けることにより得られる複室容器の補強効果と、収容室の容積が減少する不利益とのバランスをとることができる。 In the embodiment and the design modification shown in FIGS. 1 to 5, the auxiliary strong seal portions 20, 29, and 33 have the length L 1 in the adjacent direction 14 at the edge 18 of the side wall strong seal portion 16. the width length in the direction 15 (between edges 18 projecting suppressing portion 21) D 1 of the parts 20,29,33 are formed as represented by the following formula (2).
D 1 ≦ L 1 ≦ 3D 1 (2)
That is, the length L 1 in the adjacent direction 14 at the end edge 18 of the side wall strong seal portion 16 is the length in the width direction 15 of the auxiliary strong seal portions 20, 29, 33 (between the end edge 18 and the protrusion suppression portion 21). D 1 equal to or, are formed so as to be three times or less. Thereby, the balance between the reinforcing effect of the multi-chamber container obtained by providing the auxiliary strong seal portion and the disadvantage of reducing the volume of the storage chamber can be achieved.

また、補助強シール部２０，２９，３３は、補助強シール部２０，２９，３３の周端縁と、側壁強シール部１６の端縁１８とで挟まれた領域内に、未シール部４０を有している。未シール部４０を設けることにより、例えば、保存時などにおいて、複室容器１０，３７を、隔壁弱シール部１３において二つ折りし易くなる。
また、未シール部４０には、複室容器を形成するプラスチックフィルムの厚さ方向に貫通された貫通孔（図示せず）が備えられていてもよい。この貫通孔が設けられている場合には、例えば、複室容器を隔壁弱シール部１３において二つ折りにした状態で、上記貫通孔を用いて、複室容器を吊り下げることができる。また、例えば、複室容器を包装するために、二つ折にして外装袋に収納する場合において、未シール部４０に貫通孔が設けられているときには、二つ折りし易くなるという利点がある。 Further, the auxiliary strong seal portions 20, 29, and 33 are located in the region sandwiched between the peripheral edge of the auxiliary strong seal portions 20, 29, and 33 and the end edge 18 of the side wall strong seal portion 16. have. By providing the unsealed portion 40, for example, during storage, the multi-chamber containers 10 and 37 can be easily folded in two at the partition weak seal portion 13.
Moreover, the unsealed part 40 may be provided with a through hole (not shown) penetrating in the thickness direction of the plastic film forming the multi-chamber container. When this through-hole is provided, for example, the multi-chamber container can be suspended using the through-hole in a state where the multi-chamber container is folded in two at the partition weak seal portion 13. In addition, for example, when packaging a multi-chamber container and folding the container into an outer bag, when the through-hole is provided in the unsealed portion 40, there is an advantage that the container is easily folded in two.

図１〜図５に示す実施形態および設計変更例において、複室容器を形成するプラスチックとしては、特に限定されるものではなく、従来、薬液容器などに用いられている、公知の種々のプラスチック材料を採用することができる。
具体的には、例えば、ポリオレフィン、ポリ環状オレフィン、ポリエステル、ポリアミドなどの熱可塑性プラスチックのフィルムが挙げられる。なかでも、好ましくは、例えば、ホモポリエチレン、エチレン・α−オレフィンコポリマー、ポリプロピレンホモポリマー、プロピレン・α−オレフィンランダムコポリマー、プロピレン・α−オレフィンブロックコポリマーなどのポリオレフィンが挙げられる。 In the embodiment and design modification shown in FIGS. 1 to 5, the plastic forming the multi-chamber container is not particularly limited, and various known plastic materials conventionally used for chemical liquid containers and the like are used.
