　図１８は、本発明の実施形態１に係るパウチ容器の製造方法において、注出部を構成する部分にスパウトを装着させる直前の状態を示す図である。 FIG. 18 is a diagram showing a state immediately before the spout is attached to a portion forming the pouring portion in the method for manufacturing the pouch container according to the first embodiment of the present invention.
　図１８に示すように、注出部１４０を構成する部分にスパウト１４１が挿入された後、溶着接合が実施される。具体的には、第１フィルム部１１のうち第１壁部１１０の上端を構成する部分と、第２フィルム部１２とが、注出部１４０を形成しつつ互いに接合されることにより、上端接合部１３０が形成される。これとともに、注出部１４０の内面とスパウト１４１とが溶着される。これにより、図３に示すような、本実施形態に係るパウチ容器１００が製造される。 As shown in FIG. 18, after the spout 141 is inserted into the portion forming the pouring portion 140, welding and welding are performed. Specifically, the portion of the first film portion 11 that constitutes the upper end of the first wall portion 110 and the second film portion 12 are joined to each other while forming the pouring portion 140, thereby joining the upper end portion. The part 130 is formed. At the same time, the inner surface of the spout 140 and the spout 141 are welded. Thus, the pouch container 100 according to the present embodiment as shown in FIG. 3 is manufactured.
　上記のように、本発明の実施形態１に係るパウチ容器１００においては、第１折目１５１は、天襠部１０２と胴部１０１との境界であり、第２壁部１２０に形成されている。第１折目１５１は、第２壁部１２０の幅方向に沿って延びるとともに、第１壁部１１０側とは反対側に向けて突出している。本実施形態に係るパウチ容器１００の製造方法においては、第２壁部１２０を構成する部分を含む第２フィルム部１２が折り畳まれることにより、第１折目１５１が形成される。 As described above, in the pouch container 100 according to the first embodiment of the present invention, the first fold 151 is the boundary between the folds 102 and the body 101 and is formed on the second wall 120. .. The first fold 151 extends along the width direction of the second wall portion 120 and projects toward the side opposite to the first wall portion 110 side. In the method for manufacturing the pouch container 100 according to the present embodiment, the first fold 151 is formed by folding the second film portion 12 including the portion forming the second wall portion 120.
　これにより、胴部１０１と天襠部１０２との境界の一部が第１折目１５１として形成されるため、胴部１０１と天襠部１０２との境界における手触り感を向上できる。また、第１折目１５１の部分に圧力が加わっても、第１折目１５１からは内容物が噴出することがない。これにより、内容物を注出する際においては、胴部１０１と天襠部１０２との境界から内容物が噴出することを抑制することができる。 Due to this, a part of the boundary between the body 101 and the tentacle part 102 is formed as the first fold 151, so that the feel at the boundary between the body 101 and the tentacle part 102 can be improved. Further, even if pressure is applied to the portion of the first fold 151, the content does not spout from the first fold 151. As a result, when pouring out the contents, it is possible to prevent the contents from being ejected from the boundary between the body portion 101 and the tentacles portion 102.
　さらに、第１折目１５１においては溶着部が形成されないため、パウチ容器１００の外形に対して、溶着部のぶんだけ内容物の容量が減少することを抑えられる。すなわち、本実施形態に係るパウチ容器１００においては、第１折目１５１が形成されることにより、内容物の容量を増加させることができる。 Further, since the welded portion is not formed in the first fold 151, it is possible to prevent the volume of the content from being reduced by the welded portion with respect to the outer shape of the pouch container 100. That is, in the pouch container 100 according to the present embodiment, the capacity of the content can be increased by forming the first fold 151.
　さらに、胴部１０１と天襠部１０２との境界の一部が第１折目１５１であるため、胴部１０１と天襠部１０２との境界が全て接合部である場合と比較して、当該境界が柔らかくなる。これにより、胴部１０１および天襠部１０２の各々が柔軟に変形するため、パウチ容器１００に内容物を充填する際にはパウチ容器１００が容易に膨らんで、パウチ容器１００の内部へ内容物を容易に充填することができる。 Furthermore, since a part of the boundary between the body part 101 and the tentacles part 102 is the first fold 151, the boundary between the body part 101 and the tentacles part 102 is entirely compared with the case where the boundary is a joint part. The border becomes soft. As a result, each of the body portion 101 and the abdomen portion 102 is flexibly deformed, so that when the pouch container 100 is filled with the contents, the pouch container 100 easily inflates and the contents are put inside the pouch container 100. Can be easily filled.
　本実施形態に係るパウチ容器１００においては、第２折目１５２から第１折目１５１までの距離Ｄ１が、第２折目１５２から上端接合部１３０までの距離Ｄ２より小さい。本実施形態に係るパウチ容器１００の製造方法は、第２フィルム部１２が幅方向に沿って折り畳まれることにより、第２折目１５２が形成される工程を備えている。 In the pouch container 100 according to the present embodiment, the distance D1 from the second fold 152 to the first fold 151 is smaller than the distance D2 from the second fold 152 to the upper end joint 130. The method for manufacturing the pouch container 100 according to the present embodiment includes a step of forming the second fold 152 by folding the second film portion 12 along the width direction.
　これにより、本実施形態に係るパウチ容器１００は、スパウト１４１を係合可能なレール部を有する格納容器に、格納することができる。また、パウチ容器１００を製造する際においては、上端接合部１３０と山折部１５０とが互いに重なる部分がないようにすることができるため、上端接合部１３０の形成が容易となる。 With this, the pouch container 100 according to the present embodiment can be stored in the storage container having the rail portion with which the spout 141 can be engaged. Further, when the pouch container 100 is manufactured, it is possible to prevent the upper end joint portion 130 and the mountain fold portion 150 from overlapping each other, so that the upper end joint portion 130 can be easily formed.
　本実施形態に係るパウチ容器１００においては、第２壁部１２０のうち第１折目１５１から第２折目１５２までの部分の幅方向の両端部が、第２壁部１２０のうち胴部を構成する部分の幅方向の両端部に接合されることにより、端部接合部１６０が形成されている。本実施形態に係るパウチ容器１００の製造方法は、第２フィルム部１２のうち第１折目１５１から第２折目１５２までの間においてパウチ容器１００の幅方向の両端部を構成する部分が、第２フィルム部１２のうちパウチ容器１００の胴部１０１を構成する部分の幅方向の両端部に接合されることにより、端部接合部１６０が形成される工程を備えている。 In the pouch container 100 according to the present embodiment, both widthwise end portions of the second wall portion 120 from the first fold 151 to the second fold 152 form the body portion of the second wall portion 120. The end joining portion 160 is formed by joining both end portions in the width direction of the constituent portion. In the method for manufacturing the pouch container 100 according to the present embodiment, in the second film portion 12, between the first folds 151 to the second folds 152, the portions forming the widthwise end portions of the pouch container 100, There is provided a step of forming the end joint portions 160 by joining the both end portions in the width direction of the portion of the second film portion 12 forming the body portion 101 of the pouch container 100.
　これにより、パウチ容器１００の幅方向の両端部において、山折部１５０によって形成される隙間から内容物が漏れ出ることを端部接合部１６０によって防ぐことができる。 With this, at the both ends of the pouch container 100 in the width direction, it is possible to prevent the contents from leaking out from the gap formed by the mountain folds 150 by the end joints 160.
　本実施形態に係るパウチ容器１００においては、第２壁部１２０の幅方向の両端部のうち、端部接合部１６０以外の部分が、第１壁部１１０の幅方向の両端部に接合されることにより、側部接合部１７０が形成されている。端部接合部１６０の少なくとも一部が、側部接合部１７０に固定されることにより、固定部１６１が形成されている。本実施形態に係るパウチ容器１００の製造方法においては、端部接合部１６０が形成される工程において、第２フィルム部１２において第２壁部１２０を構成する部分の幅方向の両端部のうち、端部接合部１６０以外の部分が、第１フィルム部１１において第１壁部１１０を構成する部分の幅方向の両端部に接合されることにより、側部接合部１７０が形成される。端部接合部１６０が形成される工程において、端部接合部１６０の少なくとも一部が、側部接合部１７０に固定されることにより、固定部１６１が形成されている。 In the pouch container 100 according to the present embodiment, of the widthwise end portions of the second wall portion 120, the portions other than the end joint portions 160 are joined to the widthwise end portions of the first wall portion 110. Thereby, the side joint portion 170 is formed. At least a part of the end joint portion 160 is fixed to the side joint portion 170 to form the fixing portion 161. In the method of manufacturing the pouch container 100 according to the present embodiment, in the step of forming the end joining portion 160, of the widthwise end portions of the portion forming the second wall portion 120 in the second film portion 12, The side joining portions 170 are formed by joining the portions other than the end joining portions 160 to both ends in the width direction of the portion forming the first wall portion 110 in the first film portion 11.
