肉厚化では充分な効果を得ることが出来ない。The soft thin container is difficult to hold because its peripheral wall is easily deformed. Therefore, an outward flange is provided to reinforce the peripheral wall, and the entire container is integrally formed. In the case of the container, the outward flange is made of the same material as the peripheral wall of the container, so that the reinforcement by the outward flange is insufficient, so that the container must be thinned to the extent that the container is not difficult to hold. . In addition, the outward flange can increase its rigidity by increasing the thickness, but an excessive thickness will impair the appearance of the container, and an appropriate thickness that will not impair the appearance of the container. A sufficient effect cannot be obtained by the conversion.

出来る。According to the present invention, the thin container 1 made of a soft synthetic resin is used.
A rigid ring 4 made of synthetic resin, which is harder than the container, is insert-molded at the upper end of the peripheral wall 3 so that the ring forms a strong bone at the upper end of the peripheral wall 3 so that the outward flange of the upper end of the peripheral wall 3 is formed. Is strong, and the peripheral wall 3 having strong bones
By having the upper end, even a container that is easily deformed can be used without any trouble. Further, since a plurality of through holes 5 are formed in the rigid ring 4 in either the left or right or up and down directions, a molten resin material for outward flange molding flows into each of the through holes during injection molding of the container. So,
Even though the container is made of a soft synthetic resin material, there is no possibility that the rigid ring 4 will come off from the outward flange, and the outward flange and the rigid ring 4 can be surely integrated.

体とすることが出来る。In the case of the present invention, a rigid ring 4 made of a synthetic resin, which is harder than the container, is insert-molded at the upper end of the peripheral wall 3 of the thin container 1 made of a soft synthetic resin. (3) The skeleton is formed at the upper end, and therefore, even if the container has the upper end of the peripheral wall having the skeleton, the container can be easily used even if it is easily deformed.
Further, since the plurality of rod-shaped portions 11 are provided at substantially equal intervals on the upper surface or the lower surface of the rigid ring 4, the rod-shaped portions 11 are embedded in the outward flanges at the time of injection molding of the container. Regardless of the synthetic resin material, there is no possibility that the rigid ring 4 comes off the outward flange, and the outward flange and the rigid ring 4 can be surely integrated.
