As shown in FIG. 9, the outer container of the present invention is a fluid filled in a flexible bag (80) having a substantially flat rectangular shape, that is, a fluid (8) (hereinafter referred to as a bag-packed fluid). , A packaged product indicated by reference numeral (8)) together with a bag (80), as shown in FIGS. 1 and 4, as a vertically long box (A) having a substantially rectangular horizontal cross section. Be composed. As shown in FIGS. 1 and 3, an opening (3) for protruding the corner of the bag (80) is provided on the side surface of the upper half of the box (A).

In the present invention, as the material of the bag (80), an appropriate material capable of filling and packaging a fluid is selected, and a synthetic resin film for a packaging bag is usually used. Such a bag film is selected in consideration of the pressure resistance, that is, the value of the bag breaking load when a liquid fluid or the like is filled and packaged to form a bag package. Examples of the bag film include a multilayer film containing a low-density polyethylene resin obtained by copolymerizing ethylene and a specific α-olefin in a layer structure.

In the case of a multi-layer film, the base film may be polypropylene film (PP), nylon (N
Y), polyethylene terephthalate film (PE
T), ethylene-vinyl alcohol copolymer (EVO
H), polyvinyl alcohol (PVA), and other films, as well as vinylidene chloride coated films.

Particularly, a film based on nylon and polyethylene is preferable because it has excellent bag forming properties and can be easily recycled. Examples of the fluid to be filled and packaged in the bag (80) made of the above-mentioned materials include powders, granules, liquids mainly composed of liquids, and liquids. The filling amount of the fluid is usually about 60 to 90% of the maximum filling amount of the bag (80) in consideration of the pressure resistance of the bag (80).

These fluids are pillowed, for example, by a well-known filling and packaging machine using the above bag film. Pillow packaging forms a cylindrical film by bending both side edges of a continuously supplied band-shaped film, overlapping at substantially the center in the width direction and heat-sealing, and then heats the sheet perpendicular to the continuous direction of the cylindrical film. An operation of sealing and filling an object to be packaged (fluid) is continuously performed, and then, substantially the center of a seal portion formed orthogonal to the continuous direction of the film is divided. As a result, as shown in FIG. 9, a substantially flat square shape having a center seal portion at the center on one surface side, and ear-shaped seal portions projecting on upper and lower side edges perpendicular to the center seal portion is provided. Package is obtained.

As a bag forming method, a three-sided seal including the above-mentioned pillow wrapping is generally used. For example, a four-way seal that heat seals around the four sides may be used. Regardless of which bag forming method is adopted, in consideration of the strength and the packing efficiency in transportation, etc., a substantially flat rectangular bag is used as the above-mentioned bag of the fluid, particularly as shown in FIG. An ear-shaped seal portion (82) having a substantially flat rectangular shape and at least one side edge thereof;
The overhanging bag (80) is preferably used. In FIG. 9, reference numeral (82) indicates a center seal portion of the bag (80). The specification of the fluid (8) is, for example, when filling and packaging 2 liters of soft drink, the film of the bag (80) is basically made of stretched nylon / low density polyethylene / linear low density polyethylene. A film having a thickness of 70 to 120 μm included in the configuration is used, and the external dimensions are 90 to 120 m.
mx 300-350 mm x 35-45 mm (thickness).
