- These containers are mainly applied for the business use, and actually used as a container for materials of foods or medicines or as a large size container for subdivisional use.
- the inner bag for bag-in-box can be classified into following two types. That is, one is a molded type inner bag having excellent self-standing ability prepared by a blow molding method or by a vacuum molding method and another one is a film type inner bag which is prepared by thermally sealing of film which is characterized by using smaller amount of synthetic resin. Further, said film type can be classified into a plane bag type and a gazette bag type.
- JP64-9174 a gazette type bag-in-box whose gazette part is formed by folding both sides of periphery edge of the bag main-body to inner side is disclosed.
- a bag of gazette shape has following defect. That is, when the bag is filled up by liquid, since the stress is concentrated to the crossing point of crease of folding part of film located to the side surface and a heat sealed part of upper or lower side, the bag is weak against the stress such as inner pressure.
- this triangle part disturbs the easiness in handling of the filled up bag, when it is contained into an outer box.
- this triangle part becomes hard and disturbs the self-standing ability of the bag, said triangle part becomes the cause to disturb the self-standing of the filled up inner bag when it is handled without outer bag.
- the inner bag for bag-in-box to which a hand hold is attached is disclosed in Japanese Patent Laid Open Publication 2-8763.
- a heat sealed part is formed on the upper part of gazette type inner bag, and further a heat sealed part is formed so as a front film and a rear film become one body at the corner part of the inner bag. And said heat sealed part can be held by a hand.
- a heat sealed part of an upper or lower side is consisted of two heat sealed parts. That is, one is the heat sealed part locating at the center position where the front film and the rear film are faced and said front film is adhered with said rear film directly by heat sealing (this part is called as a heat sealed part), and another one is the heat sealed part locating to the outer side where the front film or the rear film is adhered with the side film by heat sealing.
- said two heat sealed part are prepared continuously to form a straight line.
- the surface and the reverse surface of the film which consist of a gazette shape inner bag for bag-in-box are usually made of thermo fusable film, and the films of the side surface are sealed by heat and adhered each other at the folded part of upper or lower side.
- a laminated film prepared by laminating multi layers so as a biaxial orientated film or a nylon resin layer which are hard to be adhered by heat sealing to be arranged at the surface is used, for the purpose to improve the intensity of inner bag, films of the side surface are not sealed by heat and not adhered each other.
