Abstract: Provided is a cap (11) used for a discharge container (1) and provided on a mouth portion (32) of a container main body (10) which is deformed by a pressing force and stores contents (100). The cap (11) includes: a base portion (51) having an annular bottom wall (64) having a discharge port (64a), an annular groove (64c) provided in an outer peripheral edge of the bottom wall (64), a flow port (64d) provided in the groove (64c), and a flow groove (64e) connected to the flow port (64d); a check valve (53) having a cylindrical support portion (81) having one end disposed in the groove (64c), a plurality of elastic pieces (82) connected to the support portion (81), and a valve body (83) connected to the plurality of elastic pieces (82) and opening and closing the discharge port (64a); and a discharge nozzle (52) covering the bottom wall (64).

Abstract: The foam-dispensing pump container according to the present invention has the valve seat portion which protrudes inwardly below the air-liquid mixing unit and which is formed of the flexible member that can come into contact with the outer peripheral face of the latch portion of the rod-shaped valve body, and immediately after the nozzle head starts rising, the flexible valve seat portion comes into contact with the rod-shaped valve body before the upper opening end of the liquid chamber comes into contact with the rod-shaped valve body, thereby significantly reducing a backflow of the foam or liquid into the air passage, and consequently improving the usability of the foam-dispensing pump container.

Abstract: A foam dispensing pump container having a suction inlet capable of introducing a large amount of external air while preventing ingress of water and foam certainly. In the foam dispensing pump container, a suction inlet 45 is opened to an opposite side of a discharging outlet 43 of the nozzle member 4. The suction inlet 45 is communicated with an air course formed between an inner cylinder 41 and an outer cylinder 42 through a through hole 46. A skirt shaped cover portion 47 is formed to extend downwardly from an outer circumferential edge of the ceiling of the nozzle member 4 to a level lower than the suction inlet 45. In order to divide and shut off an inner space of the skirt shaped cover portion 47 (i.e., a space between an inner face of the cover portion 47 and the outer cylinder 42), at least one pair of partitions 49 are formed on both sides of the suction inlet 45 in the circumferential direction of the nozzle member 4.
