【Example】
Examples of the present invention will be described below. However, the present invention is not limited to these examples as long as the gist of the present invention is not exceeded. In the composite container of the present invention, the inner bag shown in FIG. 5 was used. Moreover, regarding the lid, the same reference numerals are used for the components common to the above-described conventional lid.
[0011]
Similar to the conventional lid described above, the lid H has a square shape in plan view, and extends horizontally from the top plate h1, the side wall h2 formed around the top plate h1, and the upper end of the side wall h2. It has a flange h3 and is configured to cover the outer container by fitting the side wall h2 to the outer container. The top plate h1 is formed with a hole h6 having a diameter substantially the same as the outer diameter of the neck portion b4 into which the neck portion b4 of the plug b2 positioned below the collar portion b3 of the inner bag B can be inserted.
[0012]
In addition, the top plate h1 has a pair of arc-shaped slits h7 that have one end communicating with the hole h6 and facing the concave side, and the other end h7 ′ of the arc-shaped slit h7. A groove h9 is formed on the back surface of the top plate h1 along the straight line connecting the two lines, leaving a thin portion h8 (see FIG. 3C). Therefore, the substantially circular flap h10 formed between the pair of arc-shaped slits h7 is configured to be rotatable around the thin portion h8 that functions as a kind of hinge. Since the flap h10 is formed as described above, an arcuate recess h10 ′ constituting a part of the hole h6 is formed at the tip of the flap h10.
[0013]
By rotating the flap h10 upward, a substantially circular hole h11 connected to the hole h6 into which the neck b4 of the plug b2 can be inserted is formed. The h hole 11 is screwed with the cap b1. The stopper b2 and the flange b3 formed on the stopper b2 are formed in a size that can be inserted from the back side of the lid H. As described above, the flap h10 has a function as a kind of lid that can open and close the hole h11 into which the stopper b2 and the flange b3 into which the cap b1 is screwed can be inserted.
[0014]
To attach the inner bag B to the lid H, first, the flap h10 is rotated upward to form a substantially circular hole h11 connected to the hole h6 into which the neck b4 of the stopper b2 can be inserted. Next, as shown in FIG. 3 (a), from the back side of the lid H, the stopper b2 and the flange b3 to which the cap b1 of the inner bag B is screwed are connected to the base b2 ′ of the flange b3 and the stopper b2. Until the top plate h1 is positioned. Next, the stopper b2 is horizontally moved in the direction of the hole h6 into which the neck b4 can be inserted, and the neck b4 of the stopper b2 is inserted into the hole h6. At this time, from the outer diameter of the neck b4 formed at the boundary between the hole h11 into which the cap b2 and the collar b3 into which the cap b1 is screwed and the neck b4 of the plug b2 is inserted. The neck b4 passes through the narrow narrow part h12. However, since the top plate h1 of the lid H is formed of a deformable synthetic resin plate material, the narrow part h12 is passed when the neck b4 passes. Is expanded so that the neck b4 can pass through the narrowed portion h12.
[0015]
Next, the flap h10 is rotated downward about the thin wall portion h8 in the direction of closing the hole h11, and as shown in FIG. 3 (b), the flap h10 is curved while being bent. As shown in FIG. 3 (c), the tip is inserted between the collar b3 and the base b2 ′ of the stopper b2, and the arc shape formed at the tip of the flap h10 is formed on the outer periphery of the neck b4. The recess h10 ′ is disposed, and the neck b4 is accommodated in the hole h6. In addition, since the process of removing the inner bag B from the cover H should just perform the reverse operation | work, the description is abbreviate | omitted.
[0016]
As described above, the plug b2 and the collar portion b3 into which the cap b1 of the inner bag B is screwed are inserted into the hole h11, and then the plug b2 is horizontally moved in the direction of the hole h6 into which the neck b4 can be inserted. At the same time, the tip of the flap h10 is inserted from the side between the flange b3 and the base b2 ′ of the stopper b2, and the tip of the flap h10 is arranged on the outer periphery of the neck b4. And the flap h10 can prevent the stopper b2 from moving in the direction of the hole h11. In addition, the inner bag B can be quickly and reliably attached to the lid H, and the durability of the lid H is improved.
[0017]
【The invention's effect】
