の実施例である。 1 to 3 are examples of the composite container of the present invention.
FIG. 1 shows a tray-shaped container. A plastic container 1 vacuum-formed from a plastic sheet has an upper reinforcing sheet 2 attached to the outer side of the upper flange and the upper part of the side wall, and a lower reinforcing sheet 3 attached to the outer side of the bottom plate. FIG. 2 shows a pot-shaped container, and FIG. 3 shows a container with a lid. This shape also has the shape of two containers shown in FIG. 1 side by side, and is another embodiment of the present invention.

用の帯状の補強シート５の一部を示す。 FIG. 4 shows a method for manufacturing a composite container according to an embodiment of the present invention. The process progresses from figure A to figure E. Only a part of the vacuum forming apparatus, a female die 6 and a male die 7, are shown. A reinforcing sheet 5 and a plastic sheet 4 are placed on top of the female mold 6, and the male mold is lowered to perform press molding. Although the reinforcing sheet 5 shown in the figure is in the form of a band, it may also be a sheet. FIG. 5 shows a part of the band-shaped reinforcing sheet 5 corresponding to the composite container of the present invention shown in FIG. The contours of the upper reinforcing sheet 2 and the lower reinforcing sheet 3 are on the reinforcing sheet 5 along perforation lines 8, 9 and folding lines 10.
It is processed with. The perforation line 9 may be omitted and punched out in a later process. FIG. 6 shows a part of the band-shaped reinforcing sheet 5 for the composite container shown in FIG.

残る（図ニ，ホ）。 The explanation will be given by returning to FIG. The reinforcing sheet 5 is set on the female mold 6 so that the contoured portion of the lower reinforcing sheet 3 is directly above the bottom plate of the female mold 6. The plastic sheet 4 is heated and softened in advance (Figure A). The male mold 7 descends and the plastic sheet 4
and reinforcing sheet 5 toward the female mold (Figures B and C). When the male mold 7 further descends, only the lower reinforcing sheet 3 portion of the reinforcing sheet 5 is torn off along the cutoff line 8, completing the molding. The plastic sheet 4 and the reinforcing sheet 5 are clamped (not shown). The clamp is a separate clamp device.
Alternatively, it is clamped between the female mold and the male mold before the tearing process described above. The upper reinforcing sheet 2 remains on the upper part of the female mold (Figures D and E).
補強シートは板紙、アルミ箔などが一般的であ

る。 The reinforcing sheet is generally made of paperboard, aluminum foil, etc., but there is no particular reason to limit it. Since the adhesive is applied in advance to the side that will be in contact with the plastic sheet, it becomes sticky due to the heat of the plastic sheet, and the upper reinforcing sheet 2 and lower reinforcing sheet 3 are bonded to the outside of the plastic container 1 in a pressing process.
