Description

[Detailed Description of the Invention] The present invention relates to an inner bag storage container with a pouring spout, which is a so-called bag-in-box type container, and is particularly suitable as a container for alcoholic beverages and other liquids.

In recent years, containers such as those described above have come to be used as containers for sake, etc. This invention uses a caulking ring to firmly fix the spout of the inner bag and the cardboard outer box on the flap on the top surface, and a plastic frame inserted into the spout hole of the flap. To firmly fix the spout part and the paper container, and to prevent embrittlement due to seepage of spilled liquid into the end surface of the spout insertion hole on the top surface of the paper container when pouring liquid from the spout. By fitting a nearly concave plastic clamping frame with a groove on the outer periphery into a part of the spout insertion hole of the flap at the top of the paper box, it is possible to prevent the paper flap from getting wet and becoming brittle due to liquid. The clamping frame is tightly inserted into the rectangular horizontal ring groove on the outer periphery with a U-shaped cross section between the lower flange of the spout that is integrated with the inner bag and the threaded part for the caulking ring of the spout. It is now even more firmly fixed to the outer box without rotating.

The invention will now be explained in detail by means of illustrated embodiments.

FIG. 1 is an external view of the inner bag storage container with a spout according to the present invention, and A is a container body made of cardboard that accommodates the inner bag B with a spout. Fig. 2 is an explanatory diagram showing the parts constituting the spout part of the present invention, in which 1 is the spout body, 2 is the cap, 3 is the caulking ring, and 4 is a part of the spout insertion hole in the upper flap of the outer box. It is a clamping frame that clamps the inner edge. Further, FIGS. 3a and 3b are explanatory views of the vicinity of the upper opening of the cardboard container C for storing the inner bag of the spout according to the present invention. FIG. 4 is a partial cross-sectional view of the vicinity of the spout of the container of the present invention.

First, the spout body 1 will be explained.

The spout body 1 of the inner bag is provided with a threaded part 5 near the upper opening that engages with the threaded part 5' of the cap 2, and a threaded part 6 that engages with the threaded part 6' of the caulking ring 3 below. It will be done. This caulking ring 3
consists of a flange portion 7 and a rising cylindrical portion 8 at the center. Further, a horizontal annular groove 10 having a U-shaped cross section and a rectangular outer periphery is provided between the lower part of the caulking ring screw part 6 of the spout body 1 and the flange part 9 which is integrated with the inner bag B. On the other hand, near the upper opening of the cardboard outer box A that houses this inner bag, as shown in the explanatory diagram of FIG. A back flap 13 that overlaps with the front flap 11 has a hole 1 into which the spout of the inner bag can be easily inserted.
4 and continuous thereto, a rectangular punched portion 15 is provided in the flap portion constituting the slope. A substantially concave plastic holding frame having a groove 16 on its outer periphery large enough to insert the inner edge of the rectangular punched portion 15 is provided, and the inner edge of the rectangular punched portion 15 is inserted into this groove as shown in FIG. 3b. 16, the rectangular punched part 15 of the flap 13 is protected by the plastic clamping frame 4, and it is possible to eliminate the possibility that liquid spilled during use may enter from the end face of the cardboard and make this part brittle. In this way, the clamping frame 4 is configured to tightly fit into the outer peripheral rectangular horizontal annular groove 10 having a U-shaped cross section at the lowermost part of the spout main body, so that the spout part does not rotate. This situation is shown in the partial sectional view of FIG.

As shown in Fig. 4, a plurality of protrusions 17 are provided on the back side of the lowest flange 9 of the spout 1 to prevent the inner bag film from coming into close contact with the inside of the flange 9 and to ensure that every last drop is poured. It is configured so that it can be released.

Further, FIG. 5 is an external view illustrating the back side of the container of the present invention, and 18 is a window for checking the remaining amount.
