(Effects of the Invention) As described above, the present invention stores a blank plate obtained by punching out a laminated material having paper as a main material in a mold, and a body part formed by injecting a synthetic resin into the mold. Because the injection port with the lid is provided on the injection molded resin part of the composite container that is integrated with the top plate, unlike the conventional container with the exit port, the whole container is molded with synthetic resin or glass. , The material cost is reduced by using a blank plate, and in the conventional product, since the means for dry offset, transfer, etc. must be taken for printing on the cylinder wall surface, the present invention is expensive as a product. Since the beautiful printing can be easily performed on the paper board portion of the blank board, it is possible to easily provide a container having an outlet with a lid that is inexpensive and has a beautiful appearance.

Moreover, in spite of the composite container that was used only for rabbit horn cups, etc., since the swing port with the lid pair was formed in the injection molded resin part of the container body in which the body part and the top plate part were integrated, In terms of aspects, it is no different from conventional synthetic resin products, increasing the utility value as a composite container, and it saves resources because the synthetic resin part is small even if it is discarded after use, and it can be disposed of relatively easily.

Particularly, in the present invention, at the edge near the center of the top surface of the recessed portion provided on the top plate, a thin-walled portion in the center, a fitting protrusion, and a tab having a thin-walled portion for cutting at the tip are inserted. Since an injection-molded synthetic resin lid having a locking piece is pivotally supported, the fitting protrusion is fitted in the drawing through hole, and the locking piece is fitted in a horizontally long hole, it is used. In this case, first, by separating the lid body and the locking piece from the thin part for cutting with the knob, this locking piece remains in the horizontally long slot, which is a kind of original guarantee. It is possible to prevent tampering in container packing, and then by pressing the lid portion toward the recessed portion, the lid body bends from the thin portion and opens upward, so the contents can be easily shaken out, and the lid body Press the tip of the lid in the upright position while releasing the pressure on the gutter-shaped bent part Due to the spring action of the gutter-shaped bent portion caused by this, the lid easily returns to the flat shape, so that by pressing the flat plate of the fitting projection row, this projection row fits into the through hole row. Thus, it is possible to prevent clogging of the row of through-holes in the outlet due to steam.
