せた複合容器が知られている。 Furthermore, there is a limit to the ability to obtain thin synthetic resin containers by injection molding because the thinner the wall, the more technically difficult it becomes. Therefore, when manufacturing thin-walled containers, the flexible panel material that will form the walls of the final container is inserted and fixed into an injection mold, and synthetic resin is injected into the remaining cavity of the mold. A composite container is known in which a frame is formed by integrally joining panel materials.

Instead, the outer circumferential surface of the lid can be supported by the inwardly bent part of the upper edge rib.
A perfect seal can be achieved even if the internal pressure of the container is high. For example, if a container is filled with high-temperature liquid,
The sealing effect of the present invention is particularly remarkable.
実施例
以下、図面を参照して、本考案の実施例を説明

して示してある。 First, the embodiments shown in FIGS. 1 to 3 will be described.
The flexible panel materials 1 and 2 are integrated by a thermoplastic synthetic resin framework consisting of an upper edge rib 3, a lower edge rib 4, and a side wall rib 5 that integrally connects the upper edge rib 3 and the lower edge rib 4. The container is formed by molding. The dimensions of these frameworks, especially the upper edge ribs, are slightly exaggerated in the figures.

ｄと蓋６の外側周面とは溶着してもよいし（その
場合シール性が向上する）、溶着しなくてもよい。 To explain how to fix the lid 6, first attach the lid 6 to the inner step 3a of the upper edge rib 3 (first to second
figure). Then, the pressure receiving table 7 is applied from below to the outer step 3b of the upper edge rib 3, and the inner peripheral surface of the lid 6 is welded to the inner step 3a of the upper edge rib 3. Afterwards,
While the pressure receiving base 7 is placed on the outer step 3b of the upper edge rib 3, the upward protrusion 3c of the upper edge rib 3 is heated and pressed (Fig. 2), and bent inward to form the bent portion 3d.
(Figure 3). Then, the inner peripheral surface of the lid 6 is re-welded to the inner step 3a of the upper edge rib 3. At the same time, the bent portion 3d is pressed downward (in the figure) against the outer peripheral surface of the lid 6 to support the lid 6. Bending part 3
d and the outer peripheral surface of the lid 6 may be welded together (in that case, the sealing performance will be improved), or they may not be welded together.
なお、実際には容器内に液体等の内容物を充填

上縁リブ３の内側段部３ａに溶着する。 As shown in FIG. 6, the outer step 3 of the upper edge rib 3
b is supported from below by the pressure receiving base 7, and then the upper edge rib 3
The upward protrusion 3c is heated and bent inward to form a bent portion 3d, and at the same time, the inner circumferential surface of the lid 6 is welded to the inner stepped portion 3a of the upper edge rib 3.
この実施例でも、蓋６の外側周面は折曲部３ｄ
に溶着してもよいし、溶着しなくてもよい。 Also in this embodiment, the outer circumferential surface of the lid 6 has a bent portion 3d.
It may or may not be welded.
なお、パネル材を接合する骨組を形成させるた
