Description

このような液状物充填包装体はいずれも、軟質の積層フィルムによって形成されているため非自立形であり、これをそのままの形で単独で使用に供するには不便があることから、従来、特許文献３に示すように自立形の外容器内に収納保持して包装構造体の形態をとっていた。 Since all such liquid-filled packages are formed of a soft laminated film, they are non-self-supporting, and it is inconvenient to use them alone as they are. As shown in Document 3, it was housed and held in a self-supporting outer container to take the form of a packaging structure .

この発明の液状物充填包装構造体の一実施形態を示す平面図である。It is a top view which shows one Embodiment of the liquid filling packaging structure of this invention. この発明の液状物充填包装構造体の他の一実施形態を示す平面図である。It is a top view which shows other one Embodiment of the liquid filling packaging structure of this invention. 図２の液状物充填包装構造体の、外容器の引裂き誘導疵に沿った引裂き開封方法を示す部分拡大図である。It is the elements on larger scale which show the tearing opening method along the tear induction | guidance | derivation flaw of the outer container of the liquid filling packaging structure of FIG.

液状物充填包装体３は、ベースフィルム層とシーラント層とを具える積層プラスチックフィルムからなる包装袋本体２ａと、図１では該包装袋本体２ａの上縁部に斜め上向きに突設させたフィルム状注出ノズル５とからなる包装袋２内に、例えば、被包装物を液中シール充填により抜気した状態で密封充填したり、被包装物中に窒素等のガスを拡散させた状態で充填包装すること等により形成される。 The liquid-filled package 3 includes a packaging bag body 2a made of a laminated plastic film having a base film layer and a sealant layer, and a film projecting obliquely upward at the upper edge of the packaging bag body 2a in FIG. In the packaging bag 2 composed of the shape pouring nozzle 5, for example, the packaged object is hermetically filled in a state where the package is evacuated by filling with a liquid seal, or a gas such as nitrogen is diffused in the packaged object. It is formed by filling and packaging.

なお、セルフシール逆止機能とは、液状物充填包装体３からの被包装物の注出に当たって、フィルム状注出ノズル５の先端部分を開口（先端開口６）させた状態で、液状物充填包装体３を傾動させ、これによって、被包装物の水頭圧等によりフィルム状注出ノズル５の注出通路８の内表面どうしを大きく離隔させて、先端開口６を開放させて被包装物の所要に応じた注出を行う。この時、包装袋本体２ａが、被包装物の注出体積に応じて収縮ないしは潰れ変形するため、液状物充填包装体３内に外気を取り込むことなくその注出を行うことができる。 The self-seal check function is a liquid filling in a state in which the tip portion of the film pouring nozzle 5 is opened (tip opening 6 ) when pouring out the package from the liquid filling package 3. By tilting the packaging body 3, the inner surface of the dispensing passage 8 of the film-like dispensing nozzle 5 is greatly separated from each other by the head pressure of the packaged object, and the tip opening 6 is opened to open the packaged object. Do the dispensing as required. At this time, since the packaging bag body 2a contracts or collapses according to the volume of the packaged material, the packaging bag body 2a can be poured out without taking outside air into the liquid-filled package 3.
