Field of the Invention The present invention relates to an outer container for a liquid packaged in a bag, and more particularly to a liquid container such as a soft drink filled in a flexible bag made of polyethylene film or the like. The present invention relates to a mantle container that can be handled.

[0002]

2. Description of the Related Art Most of soft drinks such as fruit drinks and mineral spring water are filled in relatively rigid containers such as so-called PET bottles. Packaging with a PET bottle or the like can enhance design properties, secure necessary strength in the distribution process, and is excellent in handleability. On the other hand, plastic materials used for PET bottles and the like are preferably reused from the viewpoints of resource saving and environmental problems, but due to problems such as costs, they are not sufficiently recycled at present. .

[0003] For the above-mentioned beverages and the like, bag packaging using a flexible packaging material such as a polyethylene film is being studied. Up to now, bag packaging of a fluid has been mainly used for refill products such as liquid soaps and foodstuffs, and is a packaging form for the purpose of reducing packaging costs. In bag packaging, by appropriate selection of materials and bag forming methods, packaging costs can be reduced, strength in the distribution process can be sufficiently ensured, and recycling can be performed at low cost.

[0004]

However, in bag packaging, if the filled fluid (contents) is not to be used after being divided into small portions, the contents easily overflow once opened, which is inconvenient for handling and storage. Therefore, the contents are usually transferred to a rigid container after opening and used. Therefore, it is extremely inconvenient compared to packaging using a rigid container such as a PET bottle. Furthermore, beverages filled in bags, etc.
When transferred to another container or the like, there is a problem such as propagation of various bacteria in the transferred other container, which is not preferable from the viewpoint of hygiene.

[0005] The present invention has been made as a result of various studies to further enhance the advantages of packaging a fluid using a bag made of polyethylene or the like, and an object of the present invention is to simplify the fluid filled in a flexible bag. An object of the present invention is to provide a mantle container which can be handled and which can be sealed even after the bag is opened and which can be sealed securely. Another object of the present invention is to provide an outer container that can be handled hygienically even after opening a bag filled with a beverage or the like.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a bag-packed fluid envelope according to the present invention comprises a bag filled with a fluid filled in a flexible bag having a substantially flat rectangular shape. An upper casing that has a substantially rectangular horizontal cross-section by a bottomed cylindrical lower half and an upper half that can be divided into two substantially vertically. Includes two lid members at least one of which is pivotally supported by the lower half, and a structure for holding the upper end side of the bag in a closed state inside the upper end of the lid member. And sealing means for sealing an unsealed portion on the upper end side of the bag, wherein the sealing means is provided on one of the lid members.
It is characterized in that the bag is sandwiched and fitted by the groove of the strip and the one projection formed on the other lid member.

That is, in the above-mentioned mantle container, when the easily deformable fluid (package) filled in the flexible bag is loaded from the upper half of the box divided into two parts, the box remains in the bag as the fluid. Is stored according to the box. Further, when the two lid members constituting the upper half of the box are closed, the bag holding structure provided inside the upper ends of these lid members holds the bag so as to hang it, The stop means is fitted with one groove with one projection sandwiching the opened portion on the upper end side of the bag. As a result, the opened portion on the upper end side of the bag is sealed, and overflow of the fluid is prevented.

In the above outer container, if one groove is constituted by two parallel ribs which can be elastically deformed, when the groove and the projection are fitted with the opening portion of the bag interposed therebetween, the sealing is performed. The means exerts a stronger sealing force by the restoring elastic force of the two parallel ribs.

In each of the above aspects, the one groove and the one protrusion constituting the sealing means are provided so as to be gradually inclined downward from the top of the box to the side. Thereby, the opened portion of the bag whose upper end corner is cut off obliquely can be properly sealed along the opening.

Further, in each of the above aspects, it is preferable that an opening for pulling out the opened portion of the bag is provided on the divided side surface of the upper half. That is, in the opening, the opened portion of the pulled-out bag is positioned as a discharge port on the side surface of the upper half of the box. Accordingly, the box can be gripped and handled in the same manner as a rigid container. In each of the above aspects, in order to store a fluid such as a beverage in a sanitary manner, it is preferable that the upper end of the lid member is formed so as to cover the opened portion of the bag.
