Description

この発明は、接着剤、シーリング剤、セメント、アンカー剤、薬品、食品、調味料などを収容する混合用袋に関する。
更に詳しくは、内容物を長期安定的に保存するため、仕切り部によって複数に区画された収容室に内容物が封入された袋に外部から圧力を加えることにより仕切り部を連通させることにより内容物を混合する混合用袋に関する。 The present invention relates to a mixing bag containing an adhesive, a sealing agent, cement, an anchor agent, a medicine, food, a seasoning, and the like.
More specifically, in order to store the contents stably for a long period of time, the contents are communicated by applying pressure from the outside to a bag in which the contents are enclosed in a storage chamber divided into a plurality of parts by the partitions. Relates to a mixing bag.

例えば、可撓性プラスチックフィルムを使用するこの種の袋としては、２枚の可撓性プラスチックフィルムの周縁をヒートシールして袋状としたものに、その内部を複数の収容室に区画しするために仕切り部を形成したものが提案されている。その仕切り部は周縁よりも弱い剥離強度となるようにヒートシールされており、使用する直前に、袋に外部から圧力を加えることにより剥離強度の弱い仕切り部が引き剥がされ、収容室が連通することにより複数の内容物を混合することができるというものである（下記特許文献１参照）。
しかしながら、２枚の可撓性プラスチックフィルムのみから構成された袋は形状がほぼ平面状であるため、袋に膨らみを持たすことができない。したがって、少量の内容物には適しているが、比較的容量を必要とする内容物を収容するには、袋の幅や長さを大きくしなくてはならず、適さないという問題があった。 For example, as this type of bag using a flexible plastic film, the periphery of two flexible plastic films is heat-sealed into a bag shape, and the interior is partitioned into a plurality of storage chambers. For this purpose, a device in which a partition portion is formed has been proposed. The partition part is heat sealed so as to have a weaker peel strength than the peripheral edge, and immediately before use, the partition part having a weak peel strength is peeled off by applying pressure to the bag from the outside, and the storage chamber communicates. Thus, a plurality of contents can be mixed (see Patent Document 1 below).
However, since the bag composed only of the two flexible plastic films has a substantially flat shape, the bag cannot be swollen. Therefore, although it is suitable for a small amount of contents, in order to accommodate the contents that require a relatively large capacity, the width and length of the bag must be increased, which is not suitable. .

また、この種の別の袋としては、可撓性プラスチックフィルムの内部に複数の収容室を区画するために隔壁を設けられ、外部から袋に圧力を加えることにより隔壁に設けられた薄肉部から開封されて内容物を混合する袋が提案されている（下記特許文献２参照）。
袋に隔壁を持たせることにより立体性を持たせることができるため、容量の多い内容物にも適している。収容室を連通させた後には、一方の収容室内において、他方の収容室から仕切り部の連通路を通って内容物を送り込み、複数の内容物を均一に分散、混合する必要がある。例えば、接着剤やセメントなどの場合には、完全に均一に分散、混合させる必要があるため、手で袋を繰り返し揉み解すことが重要な作業の一つである。
その際に、連通路が大き過ぎると、内容物が一方の収容室から連通路を越えて他方の収容室に逆流してしまい、その結果、隔壁が邪魔となって内容物を均一に分散、混合できないという問題があった。さらに、混合した内容物を吐出させる際に、隔壁と可撓性プラスチックフィルムの隙間に混合した内容物が残留するという問題があった。
特開０４−５７７６６号公報特開０４−１０２５６２号公報 As another type of bag, a partition is provided in the flexible plastic film to divide a plurality of storage chambers, and from a thin part provided in the partition by applying pressure to the bag from the outside. A bag that has been opened to mix contents has been proposed (see Patent Document 2 below).
Since the bag can have three-dimensionality by having a partition wall, it is also suitable for contents with a large capacity. After the storage chambers are communicated, it is necessary to uniformly disperse and mix a plurality of contents in one storage chamber by feeding the contents from the other storage chamber through the communication path of the partition. For example, in the case of an adhesive, cement, etc., it is necessary to disperse and mix completely uniformly. Therefore, it is one of the important operations to squeeze the bag repeatedly by hand.
At that time, if the communication path is too large, the contents flow back from the one storage chamber over the communication path to the other storage chamber, and as a result, the contents are evenly dispersed due to the partition wall. There was a problem that mixing was impossible. Furthermore, when the mixed contents are discharged, there is a problem that the mixed contents remain in the gap between the partition wall and the flexible plastic film.
Japanese Patent Laid-Open No. 04-57766 JP 04-102562 A

この発明は上記の問題点を解消するためになされたものであり、比較的大容量の内容物にも適し、収容室を連通する連通路の大きさを制御することを可能とし、内容物を混合する際に、一方の収容室から他方の収容室への内容物の逆流を防止し、容易に内容物を均一に分散、混合することかでき、さらに、吐出させる際には、内容物の残量を軽減させることができる混合用袋を提供することを目的とする。 The present invention has been made in order to solve the above-described problems, and is suitable for contents having a relatively large capacity, enabling control of the size of a communication passage that communicates with the storage chamber. When mixing, the backflow of the contents from one storage chamber to the other storage chamber can be prevented, and the contents can be easily dispersed and mixed uniformly. It aims at providing the bag for mixing which can reduce a residual amount.

第１の課題解決手段による混合用袋は、可撓性材料からなる少なくとも前面材と後面材の周縁をヒートシールすることにより形成される袋本体の内部に、前記前面材と前記後面材の内面に山折りした可撓性材料からなるマチを形成する隔壁をヒートシールし、前記袋本体の内部を複数の収容室に区画する混合用袋であって、前記隔壁と前記前面材間及び前記隔壁と前記後面材間の少なくともどちらかに、外部から圧力を加えると剥離することにより前記収容室を連通させる連通路を形成させる弱シール部を備えていることを特徴とする。 In the mixing bag according to the first problem solving means, at least an inner surface of the front material and the rear material is formed inside a bag body formed by heat-sealing the periphery of at least the front material and the rear material made of a flexible material. A mixing bag for heat-sealing a partition wall made of a flexible material folded in a mountain and partitioning the interior of the bag body into a plurality of storage chambers, the partition wall and the front material, and the partition wall And a weak seal portion that forms a communication path that allows the storage chamber to communicate with each other by peeling off when pressure is applied from the outside.

第２の課題解決手段による混合用袋は、第１の課題解決手段において、前記袋本体の幅方向の長さＷに対する、前記隔壁のマチ幅の長さＬの比であるＬ/Ｗの値が０．２〜０．５であることを特徴とする。 The mixing bag according to the second problem solving means is a value of L / W which is a ratio of the length L of the gusset width of the partition wall to the length W in the width direction of the bag body in the first problem solving means. Is 0.2 to 0.5.

第３の課題解決手段による混合用袋は、第１または第２の課題解決手段において、隔壁のシール部の山折り部側端縁が前記袋本体の幅方向中央に弱シール部と、幅方向外側の強シール部とからなることを特徴とする。 The mixing bag according to the third problem-solving means is the first or second problem-solving means, wherein the fold-fold side edge of the seal portion of the partition wall is formed with a weak seal portion in the width direction center of the bag body, and the width direction It consists of an outer strong seal part.

第４の課題解決手段による混合用袋は、第１から第３の課題解決手段において、隔壁が舟底形を形成するようにヒートシールされていることを特徴とする。 The mixing bag according to the fourth problem solving means is characterized in that, in the first to third problem solving means, the partition walls are heat-sealed so as to form a boat bottom shape.

第１の課題解決手段の混合用袋によれば、マチを形成する隔壁を設けて立体的な袋形状にすることにより大容量の内容物を収納しても比較的コンパクトにすることができる。さらに、弱シール部を設けることにより確実に収容室を連通することが可能である混合用袋を提供できるという効果がある。 According to the mixing bag of the first problem solving means, it is possible to make it relatively compact even if a large volume of contents is accommodated by providing a partition forming a gusset to form a three-dimensional bag shape. Furthermore, there is an effect that it is possible to provide a mixing bag capable of reliably communicating with the storage chamber by providing the weak seal portion.

第２の課題解決手段の混合用袋によれば、袋本体の幅方向の長さＷに対する、隔壁のマチ幅の長さＬの比であるＬ/Ｗの値を０．２〜０．５とすることで、内容物の性状、特徴に合わせた適正な連通路を形成することができる。適当な外部からの圧力で収容室を連通することができ、誤って混合用袋を落下させたときでも、収容室が連通することを防止できる。さらに、収納室を連通させ、複数の内容物を均一に攪拌、分散、混合する際に、隔壁により連通路が封止されるため、一方の収納室から他方の収納室へ内容物が逆流することを防止することができる。さらに、内容物の残量の軽減を可能とする混合用袋を提供できるという効果がある。 According to the mixing bag of the second problem solving means, the value of L / W, which is the ratio of the length L of the gusset width of the partition wall to the length W of the bag body in the width direction, is 0.2 to 0.5. By doing so, it is possible to form an appropriate communication path that matches the properties and characteristics of the contents. The accommodation chamber can be communicated with an appropriate pressure from the outside, and even when the mixing bag is accidentally dropped, the accommodation chamber can be prevented from communicating. Further, when the storage chambers are communicated and the plurality of contents are uniformly stirred, dispersed, and mixed, the communication path is sealed by the partition walls, so that the contents flow backward from one storage chamber to the other storage chamber. This can be prevented. Furthermore, there is an effect that a mixing bag that can reduce the remaining amount of contents can be provided.

第３の課題解決手段の混合用袋によれば、弱シール部に接するように幅方向両側に強シール部を設けたことにより、連通路の大きさと形状を制御できるため、収納室を連通させ、内容物を均一に攪拌、分散、混合する際に、連通路の拡張を防止することができ、内容物の性状、特徴に合わせた混合用袋を提供できるという効果がある。 According to the mixing bag of the third problem solving means, since the strong seal portions are provided on both sides in the width direction so as to contact the weak seal portion, the size and shape of the communication path can be controlled. When the contents are uniformly stirred, dispersed, and mixed, expansion of the communication path can be prevented, and a mixing bag that matches the properties and characteristics of the contents can be provided.

第４の課題解決手段の混合用袋によれば、マチを舟底形とすることで、隔壁が十分に広がるため、外観も優れ、コンパクトな混合用袋を提供することができる。また、圧力を加える収納室に対して、隔壁を舟底形にシールすることにより、収容室を連通する際に、隔壁の幅方向の中央部に圧力を集中させることが可能な混合用袋を提供できるという効果がある。 According to the mixing bag of the fourth problem solving means, by making the gusset into a boat bottom shape, the partition wall is sufficiently widened, so that the appearance can be improved and a compact mixing bag can be provided. In addition, a mixing bag that can concentrate pressure on the central portion in the width direction of the partition wall when communicating with the storage chamber by sealing the partition wall in a boat bottom shape with respect to the storage chamber to which pressure is applied. There is an effect that it can be provided.

次に、本発明の実施形態を、図を参照しながら説明するが、本発明は実施例のみに限定されるものではない。
なお、ここで、「上下」「左右」は図１、図５のそれらをいい、また、図１に向かって手前側を「前」、同奥側を「後」というものとする。
袋本体２の幅方向の長さＷとは、左右両側シール部の端縁内側間の長さをいうものとする。また、マチ幅の長さＬとは、混合用袋１の幅方向中央における隔壁４の山折り稜線４３から弱シール部４１の山折り側端縁４４間の長さをいうものとする。 Next, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to the examples.
Here, “upper and lower” and “left and right” refer to those in FIGS. 1 and 5, and the front side in FIG. 1 is referred to as “front” and the back side is referred to as “rear”.
The length W in the width direction of the bag body 2 refers to the length between the inner edges of the left and right seal portions. Further, the length L of the gusset width means the length between the mountain fold ridge line 43 of the partition wall 4 at the center in the width direction of the mixing bag 1 and the mountain fold side edge 44 of the weak seal portion 41.

図1は本発明による混合用袋１の実施形態を示す正面図である。図２は側面を説明するための図である。 FIG. 1 is a front view showing an embodiment of a mixing bag 1 according to the present invention. FIG. 2 is a diagram for explaining a side surface.

混合用袋１は少なくとも可撓性材料からなる袋本体２と、袋本体２を複数の収容室３に区画する隔壁４を具備している。袋本体２は、ポリエチレン（ＰＥ）等の熱可塑性樹脂層を両面または片面に有する２枚の積層フィルムの前面材５と後面材６からなり、周縁７をヒートシールすることに袋状に形成される。さらに、混合用袋1の底部にマチを設けて、自立性を持たせることも可能である。
袋本体２は、例えば、外側から数μｍから２０μｍのＰＥＴフィルム、数μｍから２０μｍのナイロンフィルム、および数１０μｍから２００μｍのＰＥからなる積層フィルムである。さらにＰＥＴフィルム若しくはナイロンフィルムに、アルミナ蒸着層若しくはシリカ蒸着層を備えてもよい。積層フィルムのフィルム構成や厚みは特に限定されるものではなく、内容物の性状に合わせて、酸素バリア性や水蒸気バリア性を持たせた設計が適宜可能である。 The mixing bag 1 includes a bag body 2 made of at least a flexible material, and a partition wall 4 that partitions the bag body 2 into a plurality of storage chambers 3. The bag body 2 is composed of a front material 5 and a rear material 6 of two laminated films having a thermoplastic resin layer such as polyethylene (PE) on both sides or one side, and is formed in a bag shape by heat-sealing the peripheral edge 7. The Furthermore, it is also possible to provide a gusset at the bottom of the mixing bag 1 to provide self-supporting properties.
The bag body 2 is a laminated film made of, for example, a PET film having a thickness of several to 20 μm, a nylon film having a thickness of several to 20 μm, and a PE having a thickness of several tens to 200 μm. Furthermore, you may equip a PET film or a nylon film with an alumina vapor deposition layer or a silica vapor deposition layer. The film configuration and thickness of the laminated film are not particularly limited, and a design with an oxygen barrier property and a water vapor barrier property can be appropriately selected according to the properties of the contents.

隔壁４は一枚の可撓性材料からなる積層フィルムで構成されている。例えば、外側から数１０μｍから１００μｍのＰＥ、数μｍから２０μｍのナイロンフィルム、および数１０μｍから１００μｍのＰＥからなる積層フィルムである。ナイロンフィルムに、アルミナ蒸着層若しくはシリカ蒸着層を備えてもよい。さらに、防湿性を向上させるためにアルミニウム箔を使用してもよい。
隔壁４は山折りされた状態で、前面材５と後面材６の内部に挿入され、前面材５と後面材６の内面とそれぞれヒートシールされる。隔壁４は外部から圧力を加える収容室３側に山折りに固定されている。
収容室３は、第一収容室３１、第二収容室３２、さらにそれ以上に区画することもでき、それぞれ、液状体、粒状体、粉状体、固体などが収容される。内容物は特に限定されるものではない。 The partition 4 is composed of a laminated film made of a single flexible material. For example, it is a laminated film made of PE of several tens to 100 μm, a nylon film of several to 20 μm, and PE of several tens to 100 μm from the outside. The nylon film may be provided with an alumina vapor deposition layer or a silica vapor deposition layer. Furthermore, an aluminum foil may be used to improve moisture resistance.
The partition wall 4 is inserted into the front member 5 and the rear member 6 in a state of being folded in a mountain, and the inner surfaces of the front member 5 and the rear member 6 are heat sealed. The partition wall 4 is fixed in a mountain fold on the side of the storage chamber 3 to which pressure is applied from the outside.
The storage chamber 3 can also be partitioned into a first storage chamber 31, a second storage chamber 32, and more, and each stores a liquid material, a granular material, a powdery material, a solid, and the like. The contents are not particularly limited.

隔壁４と前面材５の内面及び隔壁４と後面材６の内面との間の、少なくともどちらかに弱シール部４１を形成している。弱シール部４１は、袋本体２の周縁７や他の隔壁４のシール部よりも剥離強度が弱いシール部分のことをいう。弱シール部４１は隔壁４と前面材５及び隔壁４と後面材６の間にイージーピールフィルム８を挟んで、ヒートシールすることにより形成できる。
イージーピールフィルム８の形状、大きさは特に限定されるものではないが、袋本体２の幅方向、両側端まで直線状に挿入すれば、袋の製造が容易となり、製造コストを低減できる。
また、イージーピールフィルム８は隔壁４の下部より少しだけ下方にはみ出した状態で挿入されるのが好ましい。弱シール部４１の剥離強度は５〜１５Ｎ程度であり、強シール部４２の剥離強度は７０〜９０Ｎ程度である。 A weak seal portion 41 is formed at least either between the partition wall 4 and the inner surface of the front member 5 and between the partition wall 4 and the inner surface of the rear member 6. The weak seal portion 41 refers to a seal portion whose peel strength is weaker than that of the peripheral edge 7 of the bag body 2 and the seal portions of the other partition walls 4. The weak seal part 41 can be formed by sandwiching an easy peel film 8 between the partition wall 4 and the front surface material 5 and between the partition wall 4 and the rear surface material 6 and heat-sealing.
Although the shape and size of the easy peel film 8 are not particularly limited, if the bag body 2 is linearly inserted to the width direction and both side ends, the bag can be easily manufactured and the manufacturing cost can be reduced.
Moreover, it is preferable that the easy peel film 8 is inserted in a state of protruding slightly below the lower part of the partition wall 4. The peel strength of the weak seal portion 41 is about 5 to 15N, and the peel strength of the strong seal portion 42 is about 70 to 90N.

図３は隔壁４のシール形状について説明するための図である。
隔壁４のシール形状は図３（ａ）に示した直線の帯状の弱シール部４１のみから形成することができる。また、図３（ｂ）〜（ｄ）に示したような、隔壁４のシール部の山折り部側の端縁４４において、袋本体２の幅方向中央に弱シール部４１を設け、弱シール部４１の左右両側に隣接するように強シール部４２を設けることもできる。強シール部４２の形状は特に限定されるものではなく、袋本体２に外部から圧力を加えた場合、圧力が弱シール部４１に集中し、かつ、弱シール部４１に形成される連通路９の拡張を防止することができる形状であればよい。
図３（ｂ）に示すような隔壁４のシール形状を円弧形状とし、収容室３に内容物を充填した際に、隔壁４が舟底形の形状となるようにヒートシールするのが好ましい。美的な外観を有し、かつ、大容量の内容物を収納しても比較的コンパクトにすることができるからである。 FIG. 3 is a view for explaining the seal shape of the partition 4.
The seal shape of the partition wall 4 can be formed only from the straight belt-like weak seal portion 41 shown in FIG. Further, as shown in FIGS. 3B to 3D, a weak seal portion 41 is provided at the center in the width direction of the bag body 2 at the edge 44 on the mountain fold side of the seal portion of the partition wall 4, thereby providing a weak seal. The strong seal portion 42 may be provided so as to be adjacent to the left and right sides of the portion 41. The shape of the strong seal portion 42 is not particularly limited, and when pressure is applied to the bag body 2 from the outside, the pressure concentrates on the weak seal portion 41 and the communication passage 9 formed in the weak seal portion 41. Any shape can be used as long as it is possible to prevent the expansion.
It is preferable that the seal shape of the partition wall 4 as shown in FIG. 3B is an arc shape and heat sealing is performed so that the partition wall 4 has a boat bottom shape when the storage chamber 3 is filled with contents. This is because it has an aesthetic appearance and can be made relatively compact even if it contains a large amount of contents.

つぎに、連通路９の形成について、図４、図５を用いて説明する。図４は隔壁４のシール形状を円弧形状とし、隔壁４が舟底形である袋本体２に内容物を充填した状態の図である。図５は連通路９の形成を説明するための図である。
収容室３に外部から圧力を加えると、隔壁４のシール部の山折リ部側端縁の最下点付近ｘに応力が集中するため、最下点付近から剥離し始める。そして、強シール部４２と弱シール部４１の境界の隔壁４のシール部の山折り部側の端縁ｙ１、ｙ２から接線方向に剥離する。２本の接線ｙ１１、ｙ２１によってＶ字状に連通路９が形成される。連通路９の開口９１とは、連通路９の最狭部をいい、Ｖ字状の連通路９では、隔壁４のシール部の最下部をいうものとする。 Next, the formation of the communication path 9 will be described with reference to FIGS. FIG. 4 is a view showing a state in which the seal shape of the partition wall 4 is an arc shape and the bag body 2 in which the partition wall 4 has a boat bottom shape is filled with contents. FIG. 5 is a view for explaining the formation of the communication passage 9.
When pressure is applied to the storage chamber 3 from the outside, stress concentrates in the vicinity of the lowest point x of the edge of the partition wall 4 on the side of the mountain fold, so that the separation starts from the vicinity of the lowest point. And it peels in the tangential direction from the edge y1, y2 by the side of the mountain fold part of the seal part of the partition 4 of the boundary of the strong seal part 42 and the weak seal part 41. FIG. The communication path 9 is formed in a V shape by the two tangent lines y11 and y21. The opening 91 of the communication passage 9 refers to the narrowest portion of the communication passage 9, and the V-shaped communication passage 9 refers to the lowermost portion of the seal portion of the partition wall 4.

マチ幅の長さＬを袋本体２の幅方向の長さＷに対して、変更することによって、連通させるために必要な応力や連通路９の開口９１の幅Ｚを調整することができる。 By changing the length L of the gusset width with respect to the length W of the bag body 2 in the width direction, the stress necessary for communication and the width Z of the opening 91 of the communication passage 9 can be adjusted.

また、図１に示すように、袋本体２の各収容室３と外部を連通するように充填口及び吐出口を設けることができる。充填具材１０及び吐出具材１１を前面材５と後面材６との間に挿入し、周縁７をヒートシールすることに形成することができる。充填具材１０としては特許第３４３２２２７号公報に記載されている構造のものが好ましい。再封止可能な連結部材であるため、空気の介入を抑制でき、内容物を充填した際に、隔壁４を十分に広げることができるからである。 In addition, as shown in FIG. 1, a filling port and a discharge port can be provided so as to communicate each storage chamber 3 of the bag body 2 with the outside. The filler material 10 and the discharge material 11 can be inserted between the front material 5 and the rear material 6 and the peripheral edge 7 can be heat sealed. The filling material 10 is preferably one having a structure described in Japanese Patent No. 3432227. Because it is a resealable connecting member, it is possible to suppress the intervention of air, and when the contents are filled, the partition 4 can be sufficiently expanded.

吐出具材１１の上部にはシール部が設けられており、袋本体２のフィルムと固定されている。袋本体２の周縁７下部は内容物を吐出しやすいように吐出具に向かって次第に細くなる傾斜を設けることができる。 A seal portion is provided on the upper part of the discharge tool material 11 and is fixed to the film of the bag body 2. The lower part of the peripheral edge 7 of the bag body 2 can be provided with a slope that becomes gradually narrower toward the discharge tool so that the contents can be easily discharged.

次に本発明の効果を明らかにするために実施例を説明する。
［実施例１］
上記実施形態の混合用袋を使用した場合における、隔壁のシール形状における混合用袋の連通直後の連通路の開口の幅と混合・吐出後の連通路の開口の幅の変化と、排出後の内容物の残量を測定した。 Next, examples will be described in order to clarify the effects of the present invention.
[Example 1]
When the mixing bag of the above embodiment is used, the change in the width of the opening of the communication path immediately after the communication of the mixing bag in the seal shape of the partition wall, the change in the width of the opening of the communication path after mixing and discharging, The remaining amount of contents was measured.

袋本体の高さ２８０ｍｍ、袋本体の幅の長さＷを１１０ｍｍ、マチ幅の長さＬを４０ｍｍとし、隔壁のシール形状を（Ａ）直線形状としたものと、（Ｂ）円弧形状としたものを用いて測定した。
第一収容室には水１５０ｃｍ³、第二収容室には粉体のセメントモルタル５５０ｃｍ³を収容し、左右両側面の周縁を中心に向かって手で掴んで押えることにより、第一収容室と第二収容室を連通させた。第一収容室の水を第二収容室に送り込んで、手で揉むことにより、水とセメントを攪拌、分散、混合を行った。その後、内容物を第二収容室から全量吐出させた。表１には吐出後の内容物の残量と残量率を示した。表２には連通直後と、内容物を混合・吐出した後の連通路の開口の幅の長さを示した。連通路の開口の長さは隔壁のシール部の最下部を測定した。

The height of the bag body is 280 mm, the width W of the bag body is 110 mm, the length L of the gusset width is 40 mm, and the seal shape of the partition wall is (A) a straight shape, and (B) the arc shape. It measured using the thing.
First chamber to the water 150 cm ^3, by the second accommodation chamber accommodating the cement mortar 550 cm ³ of a powder, pressing grabbed by hand towards the center of the periphery of the left and right side surfaces, a first chamber The second containment chamber was connected. Water and cement were agitated, dispersed, and mixed by feeding the water in the first storage chamber into the second storage chamber and squeezing it by hand. Thereafter, the entire contents were discharged from the second storage chamber. Table 1 shows the remaining amount and remaining rate of the contents after ejection. Table 2 shows the width of the opening of the communication path immediately after communication and after mixing and discharging the contents. The length of the opening of the communication path was measured at the bottom of the seal part of the partition wall.

表1、表２から明らかなように、隔壁のシール形状を直線形状とした場合、連通直後の連通路の開口の幅が大さかった。混合、吐出によりさらに拡張した。隔壁のシール形状を円弧形状とした場合、強シール部によって制御されるため、連通直後の連通路の開口の幅は小さかった。また、混合、吐出により連通路の開口の拡張が抑制された。隔壁のシール形状を直線形状とした場合、内容物が連通路の開口から連通路を通って、他方の収容室に逆流してしまうため、隔壁に内容物が付着し、残量が多くなった。しかし、混合が容易で、内容物の残量が少ないと考えられる液体と液体の混合には直線形状も使用できる。円弧形状は、内容物の逆流が少ないため、内容物の残量を少なくすることができた。 As is apparent from Tables 1 and 2, when the seal shape of the partition wall was a straight line shape, the width of the opening of the communication path immediately after the communication was large. Further expanded by mixing and discharging. When the seal shape of the partition wall is an arc shape, the width of the opening of the communication path immediately after communication is small because it is controlled by the strong seal portion. Moreover, the expansion of the opening of the communication path was suppressed by mixing and discharging. When the seal shape of the partition wall is a straight shape, the contents flow back from the opening of the communication path through the communication path to the other storage chamber, so the contents adhere to the partition wall and the remaining amount increases. . However, a linear shape can also be used for mixing liquids that are easy to mix and are considered to have little residual content. Since the arc shape has less backflow of contents, the remaining amount of contents could be reduced.

［実施例２］
また、上記実施形態の混合用袋における、一定の袋本体の幅方向の長さＷに対して、隔壁のマチ幅の長さＬを変更した場合の連通直後の連通路の開口の幅、混合・吐出後の連通路の開口の幅と、連通に必要な荷重を測定した。
袋本体の幅方向の長さＷを１１０ｍｍとし、袋本体の高さ２８０ｍｍとした。第一収容室には水１５０ｃｍ³、第二収容室には水溶性接着剤５５０ｃｍ³を収容し、左右両側面周縁を中心に向かって手で掴んで押えることにより、第一収容室と第二収容室を連通させた。第一収容室の水を第二収容室に送り込んで、手で揉むことにより、攪拌、分散、混合を行った。その後、内容物を第二収容室から全量吐出させた。連通に必要な荷重はオートグラフにより測定した。 [Example 2]
Further, in the mixing bag of the above embodiment, the width of the opening of the communication passage immediately after communication when the length L of the gusset width of the partition wall is changed with respect to the length W in the width direction of the fixed bag body, mixing -The width of the opening of the communication passage after discharge and the load required for communication were measured.
The width W of the bag body was 110 mm, and the height of the bag body was 280 mm. First chamber to the water 150 cm ^3, the second chamber containing a water-soluble adhesive 550 cm ^3, by pressing grabbed by hand towards the center of the left and right sides periphery, a first chamber a second The containment room was in communication. The water in the first storage chamber was fed into the second storage chamber and stirred by hand to perform stirring, dispersion, and mixing. Thereafter, the entire contents were discharged from the second storage chamber. The load required for communication was measured by an autograph.

表３から明らかなように、Ｌ/Ｗの値を漸次大きくすると、すなわちマチ幅Ｌを大きくすると、連通路の開口の大きさが小さくなり、また、連通させるために必要な荷重は大きくなった。
特にＬ/Ｗの値が０．２〜０．５が好ましい。Ｌ/Ｗの値が０．２より小さいときは、容易に連通してしまうため、輸送時や製品を誤って落下させた際に、連通してしまうことがある。また、連通口が大きいため、攪拌、混合、分散の際に内容物の逆流が大きく、隔壁に内容物が付着し、内容物の残量が大きくなった。
Ｌ/Ｗの値が０．５より大きいときは、連通させるのに過剰な荷重が必要となり、女性などは連通させることが困難であった。また、連通路が小さいため、混合が困難であった。 As is apparent from Table 3, when the value of L / W is gradually increased, that is, when the gusset width L is increased, the size of the opening of the communication path is reduced, and the load necessary for communication is increased. .
In particular, the L / W value is preferably 0.2 to 0.5. When the value of L / W is smaller than 0.2, communication is easily performed, and therefore communication may occur during transportation or when a product is accidentally dropped. Moreover, since the communication port was large, the back flow of the contents was large during stirring, mixing, and dispersion, the contents adhered to the partition walls, and the remaining amount of the contents increased.
When the value of L / W was larger than 0.5, an excessive load was required for communication, and it was difficult for women and the like to communicate. Further, since the communication path is small, mixing is difficult.
