キャップ付き容器

Japanese Patent JP4160163

B2

An object of the present invention is to provide a container (21) having a cap capable of simplifying an unsealing operation, improving resealability against leakage of the contents thereof, and reducing cost. The container (21) includes a container body (22) having a rupture portion for forming a discharge opening, and a cap (23) attached to the container body (22) in correspondence to the rupture portion. The cap (23) includes an annular base member (25) fixedly attached to the container body (22); a screw cap (27); and a retainer (26) including an unsealing member formed at a tip for rupturing the rupture portion, a first screw-engagement portion defined in cooperation with the base member (25), and a second screw-engagement portion defined in cooperation with the screw cap (27). The first and second screw-engagement portions have screw-engagement directions opposite to each other. The screw cap (27) and the retainer (26) include a rotation control portion, which inhibits relative rotation therebetween when a force not greater than an allowable value is applied thereto and which permits relative rotation therebetween when a force greater than the allowable value is applied thereto. After the rupture portion is ruptured, the retainer (26) is moved axially by a predetermined amount and is then stopped by a stop mechanism.
