  • Patent number: 11155386
    Abstract: A container includes a container body; and a cap that locks onto the container body, the container body and the cap being locked by putting the cap on the container body. The cap includes a cap body, a cover cap being held on the cap body so as to be displaceable and rotatable, and an urging portion that upwardly urges the cover cap. When a rotational force is applied to the cover cap being downwardly pressed, the cap body is displaced in conjunction with the cover cap, so that locking between the cap body and the container body is released, and in a state where the cover cap is not downwardly pressed, the cap body is not displaced in conjunction with the cover cap even when a rotational force is applied to the cover cap, so that locking between the cap body and the container body is not released.

  • Publication number: 20110031207
    Abstract: A liquid container comprises a container body (1) and a cap (2). The container body (1) has a circular tubular neck portion (13) with an outer peripheral surface provided with a protrusion (13a) for locking the cap (2). The cap (2) has a pair of lockable arms (24) arranged in a lateral direction and each provided with a hook portion (24a) adapted, during an operation of attaching the cap (2) to the container body (1), to be engaged with the locking protrusion (13a). Further, the cap (2) internally has a pair of first reinforcing ribs (26) each adapted to restrict a flexural displacement of a respective one of the lockable aims (24) in the lateral direction, and a pair of second reinforcing ribs (28) each connecting an inner surface of the cap and a respective one of the lockable arms (24) in a frontward-rearward direction.

  • Publication number: 20110024426
    Abstract: A liquid container has a body (1) and a cap (2). A circular tubular neck (12) of the body (1) has an outer diameter greater than a maximum diameter of a nozzle (14), and a locking protrusion (124) for the cap (2) is provided on an outer peripheral surface of the circular tubular neck. The cap (2) has two lockable arms (24). The lockable arms (24) are locked onto the locking protrusion (12a) while attaching the cap (2) to the body (1). Opposing surfaces (26) of the lockable arms (24) define guide surfaces that contact the outer peripheral surface of the circular tubular neck (12) during the cap attaching operation to guide the cap (2) along the circular tubular neck (12) so as to allow a plug protrusion (22) of the cap (2) and a nozzle hole (14a) to oppose each other.

  • Patent number: 7213727
    Abstract: A lower portion of a nozzle is held hermetically in contact with an inner circumferential surface of the tubular neck of a container, and an inner surface of a cap is mounted to an outer surface of the tubular neck. A discharging hole of the nozzle is hermetically sealed by an inner top surface of the cap. A ring-shaped projection is formed on an upper portion of the nozzle for hermetically contacting an inner surface of the cap. Thereby, double sealing is provided in cooperation with hermetic sealing of the discharging hole of the nozzle by the inner top surface of the cap. The nozzle prevents a liquid leak and liquid dripping from the nozzle and form liquid drops independently of a dripping angle.
