ABSTRACT:
The present invention provides a retortable container which has an engagement ridge (19), of an outer diameter D.sub.1 smaller than an inner diameter D.sub.2 of a thread of a cap (20), formed on the outer circumference of the neck (13) near the top face thereof and an engagement portion (26) having an engaging hook (26a), capable of engaging with the engagement ridge (19) of the neck (13) under the condition that engagement of the neck (13) and the cap (20) is completed, being formed integrally therewith on the bottom surface of the top wall (21) of the cap (20), whereas the engagement portion (26) is formed in a shape of cylinder having a wall thickness smaller than the wall thickness of the circumferential wall (28) of the cap (20), and the engaging hook (26a) protrudes in an annular shape inwardly from the open bottom end of the engagement portion (26). This configuration of the container is capable of preventing the cap (20) from coming off and the screw engagement of the container body and the cap (20) from loosening during sterilization process, and allows it to detach the cap (20) with less force (FIG. 2).
