3) is formed. In addition, around the bottom corner of the inner wall (11), there is a stopper (
14) is formed. This stopper (14) is
They are partially protruded at several locations around the corners, and the height of the protrusion is equal to or less than the thickness of the paper tube (3). Then, the tube paper (3) is positioned more accurately by the stopper (14) and the female mold (
1) The device is installed in a state where it is suspended from the bottom (12) at a predetermined height. In addition, if the inner paper (3) has a tapered shape and has the ability to maintain its shape, it can be positioned along the inner wall (11) of the female mold (1). The L-flange (14) does not necessarily have to be formed.

形する(第2図参照)。Next, a heated polystyrene foam 1, etc., which is the main material of the composite container (4), is placed between the male mold (2), which has an opposing cleft C provided on the female mold (1), and the above-mentioned metal mold (1). The foamed sheet 1-(lI) of plastic resin is fed along with mold clamping to form the foamed sheet 1-(lI) along the convex portion (20) of the male mold (2) (see FIG. 2).

なったりする不都合を回避できることになる。The convex portion (20) of the male mold (2) has a clearance (C) between 2 and 2 to the inner wall (11) of the female mold (1) during mold clamping.
The outer diameter is relatively small, preferably 10 mm, preferably 3 to 6 mm. That is, the clearance (C) is set to be slightly larger than the thickness dimension (usually 1.0 to 2.0 mm) of the foam sheet (11). Therefore, during molding, each foam sheet 1 to (11) is molded in a non-contact state with respect to the tube paper (3) loaded in advance. Therefore, the tube paper (3) is the foam sheet (II).
This will avoid the inconvenience of being pulled in and shifting downward, folding, or wrinkled.

If the temperature is too low, cracks will occur in the molded part, while if the temperature is too high, no cracks will occur, but it will take a long time to cool down, which will lengthen the molding cycle. , there are problems such as sagging in the thickness of the molded part.

参照)。Then, at the same time as the above molding by the male mold 3° ((2) is completed, compressed air is supplied from the air supply hole (21) of the male mold (2), and the vacuum suction hole (1) of the mold 11 (1) is completed.
3) Apply a vacuum to the molded part (of the foam sheet).
I+') The outer periphery is expanded in the radial direction so as to lie along the tube paper (3) and the inner wall (11) of the type II (1) below it. Then, the outer periphery of the molded part (II') can be brought into strong contact with the paper sleeve (3), and the two can be joined and integrated with the adhesive applied to the inner surface of the paper sleeve (3). (see figure).

F21等の温度低下を防止できて好ましい。The pressure of the compressed air needs to be in the range of 0.5 to 5+14, preferably 1.0 to 2.5 to 94, and if the pressure is higher than that, the thickness of the foamed sheet 1-(Ill) will decrease. If the temperature is lower than that, the adhesion between the foam sheet (old paper) and the tube paper (3) will deteriorate significantly.
Foam sheets (old and male and female type (11
This is preferable because it can prevent a temperature drop in F21 and the like.

Jるリップ強度は、06にってあった。The composite container (4) formed in this way is an integrally molded product in which the foam sheet (11) and the tube paper (3) are completely adhered to each other, so the tube paper is attached after the fact. For example, even when made of the same material, the lip strength (compression speed of 500 nun/min, 25 mm compression) is higher than that of the composite container formed by the molding method according to the present invention.
4) had a strength of 1.27 kIJ, whereas the strength of the pipe with a tube attached after the fact was 1.03 kIJ, and it has been confirmed that the strength can be increased by about 20%. Therefore, if the same strength is to be maintained, the foam sheet (
