Title (EN) PACKAGING BAG FOR CONTAINING LIQUID, SPOUT MEMBER, AND ARTICLE
(FR) SAC D'EMBALLAGE POUR CONTENIR UN LIQUIDE, ÉLÉMENT DE BEC VERSEUR, ET ARTICLE
(JA) 液体収納用包装袋、注出部材および物品
Abstract:
(EN) The present invention relates to a packaging bag for containing liquids in which the bag main body and the spout member can be satisfactorily bonded to each other. Provided is a packaging bag (1) for containing liquids which comprises: a bag main body (2) for containing liquids that is constituted of films (21); and a spout member (3) having a spout opening (R). The packaging bag (1) for containing liquids is characterized in that the bag main body (2) has a first bonded part (22) provided to the films (21) and bonded to the spout member (3) and a peripheral bonded part (23) which has been disposed on the peripheral part of the bag main body (2) and in which the films (21) have been lap-bonded to each other, the first bonded part (22) comprising a fluorinated bonding material, which is a fluororesin material having a melting point of 230ºC or lower. The packaging bag (1) is further characterized in that the spout member has a second bonded part (32) bonded to the first bonded part (22) of the bag main body (2), the part where the first bonded part (22) and the second bonded part (32) have been bonded comprising an affinitive material having an affinity for the fluorinated bonding material, the affinitive material being a resin material containing at least one polar functional radical selected from among an amide bond, halogeno radicals, a hydroxy group, cyclic anhydride groups, and a cyano group.
(FR) La présente invention concerne un sac d'emballage pour contenir des liquides, dans lequel sac le corps principal de sac et l'élément de bec verseur peuvent être liés de manière satisfaisante l'un à l'autre. A cet effet, l'invention porte sur un sac d'emballage (1) pour contenir des liquides, lequel sac comprend : un corps principal de sac (2) pour contenir des liquides, qui est constitué par des films (21) ; et un élément de bec verseur (3) ayant une ouverture de bec verseur (R). Le sac d'emballage (1) pour contenir des liquides est caractérisé en ce que le corps principal de sac (2) a une première partie liée (22) disposée sur les films (21) et liée à l'élément de bec verseur (3) et une partie liée périphérique (23) qui a été disposée sur la partie périphérique du corps principal de sac (2), et dans laquelle les films (21) ont été liés par recouvrement les uns aux autres, la première partie liée (22) comprenant un matériau de liaison fluoré, qui est un matériau de résine fluorée ayant un point de fusion inférieur ou égal à 230° C. Le sac d'emballage (1) est en outre caractérisé en ce que l'élément de bec verseur a une seconde partie liée (32), liée à la première partie liée (22) du corps principal de sac (2), la partie où la première partie liée (22) et la seconde partie liée (32) ont été liées comprenant un matériau à affinité ayant une affinité pour le matériau de liaison fluoré, le matériau à affinité étant un matériau de résine contenant au moins un radical fonctionnel polaire choisi parmi une liaison amide, des radicaux halogénés, un groupe hydroxy, des groupes d'anhydrides cycliques, et un groupe cyano.
(JA) 本開示は、袋本体および注出部材を良好に接合させることが可能な液体収納用包装袋に関する。 フィルム(21)で構成され液体を収納する袋本体(2)と、注出口(R)を有する注出部材(3)とを備える液体収納用包装袋(1)であって、上記袋本体(2)は、上記フィルム(21)に設けられ、上記注出部材(3)と接合された第1接合部(22)と、上記袋本体(2)の外周部に配置され、上記フィルム(21)が重ね合わされて接合された外周部接合部(23)とを有し、上記第1接合部(22)は、含フッ素接合性材料を含み、上記含フッ素接合性材料は、融点が230℃以下の含フッ素樹脂材料であり、上記注出部材は、上記袋本体(2)の上記第1接合部(22)と接合された第2接合部(32)を有し、上記第1接合部(22)と上記第2接合部(32)との接合部分には、上記含フッ素接合性材料と親和性を有する親和性材料を含み、上記親和性材料は、アミド結合、ハロゲノ基、水酸基、環状無水物基、およびシアノ基の少なくとも一つの極性官能基を含む樹脂材料であることを特徴とする液体収納用包装袋(1)を提供する。
