Abstract

PURPOSE:To achieve saving of resources and reduce manufacturing costs by inserting a waterproof inner bag into a hexahedral box made of cardboard or thick paper. CONSTITUTION:A waterproof inner bag 9 comprising two-sided body is inserted into a cardboard box 1 and opposite sides 10, 11 are bonded to the inner side of left and right fold lines 7, 8. An injection port 12 with a cap attached to the bag 9 is exposed to the outside of the box 1 through a through-hole provided in an opening side closing piece 6 of the box 1. If the box 1 is folded into a flat form along the fold lines 7, 8, since both the sides 10, 11 are bonded to the inner side of the lines 7, 8, the inner bag 9 also is folded into a flat form. Under such condition, if the fold line parts 7, 8 are pushed inward, the box 1 is extended to a quadrilateral. In such condition, the bottom of the box 1 is closed by means of closing pieces 6.... and the content is filled into the bag 9 from the port 12 and the cap is closed to close the opening of the box 1. As a result an outer bag can be eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention inserts a watertight inner bag into a hexahedron box made of cardboard or cardboard to transport or store liquid instead of a metal or plastic molded container. The present invention relates to a package (packaging unit) that can be used.

[0002]

2. Description of the Related Art As a conventional packaging unit, Japanese Patent Laid-Open No. 1-
The one disclosed in Japanese Patent No. 279070 is known. In this known example, a folding line (fold) is attached to the center of both side walls of a paper support, an inner bag made of a dihedron is inserted into the inside of the support, and both sides of the inner bag are connected to the folding line. The inside and outside are watertight structure in which the inside is sealed and the inside is sealed by inserting the inside into an exterior bag made of a dihedron.

[0003]

SUMMARY OF THE INVENTION In the above known example,
Although the outer side of the support is sealed with an outer bag for the purpose of waterproofing from the outside, it may not be necessary to consider the waterproofing from the outside depending on the distribution channel and storage conditions. As a result, in a packaging unit that is effective in saving resources or solving problems in waste disposal, an excessive function is added depending on the application, and the cost is also high.

The object of the present invention is to propose a package which does not become over-functional and can be provided at low cost.

[0005]

The structure of the package according to the present invention is as follows.

[0006] A vertical inner fold line is formed in the center of the left and right side surfaces of the body that can be formed into a hexahedral box when assembled, and a watertight inner bag made of a dihedron is inserted inside the body. A package formed by arranging both sides of a watertight inner bag along inner fold lines of the body and adhering a part of both sides to the body.

[0007]

[Function] Usually, the body and the inner bag are flatly folded along the folding lines on the left and right sides. When filling the contents in this, when pushing the left and right fold lines inward, the skeleton expands into a quadrangle, so first close the bottom four side blocking pieces to form the bottom, and from the mouth side inside the inner bag Is filled with the contents and sealed, and then the mouth side closing piece is folded to close the mouth side of the body. A closable inlet may be attached to the inner bag, or the inner bag may be filled with contents and then sealed by heat sealing or the like.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of a package according to the present invention folded flat. Reference numeral 1 is a flat quadrangular cardboard box (frame) formed by forming front 2 and back 3 and left and right side surfaces 4 and 5 and closing pieces 6 on the upper and lower sides. Lines (folds) 7 and 8 are formed.

9 is a watertight inner bag made of a dihedron,
The inner bag 9 is inserted into the cardboard box 1 and has both sides 10 and 11 bonded inside the left and right folding lines 7 and 8. Reference numeral 12 denotes an injection port with a cap attached to the inner bag 9, and the injection port 12 is inserted through a through hole provided in the mouth side closing piece 6 of the cardboard box 1 as shown in FIGS. Exposed outside.

As shown in FIG. 1, the packaging body of the above embodiment is flatly folded along the left and right folding lines 7 and 8,
At this time, the inner bag 9 is also flatly folded because both sides 10, 11 are adhered to the inside of the folding lines 7, 8. In this state, push the left and right fold lines 7 and 8 inward,
The cardboard box 1 spreads out in a quadrangle as shown in FIG. In this state, the bottom of the cardboard box 1 is closed, and then the contents are filled into the inner bag 9 through the inlet 12 and the cap is closed to close the mouth side of the cardboard box 1. This state is shown in FIG.

[0011]

As described above, according to the present invention, the body is made of cardboard or cardboard, and the inner bag is inserted into the body having a fold line at the center of the left and right side surfaces. Since both sides are adhered, if you fold the skeleton along the fold line and fold it flatly, the inner bag will also fold flat and expand the skeleton into a square and fill the contents in the inner bag, this inner bag will be quadrangled by the skeleton It is formed on the body and protected by the body.
Therefore, it is effective for transporting and storing liquids, and by eliminating the outer bag, it is possible to save resources and reduce manufacturing costs.
