    Abstract: [Object] To provide a trigger-type pump dispenser A which is configured such that a trigger section 13 is depressed by a thumb with a handle gripped, which is good in grippability, which allows efficient transmission of finger pressure to the trigger section 13 during spraying, and which is excellent in operation.[Solution] The present invention is directed to a trigger-type pump dispenser including: a cylinder section; a handle section 12; a trigger section 13 located above the handle section 12; and a nozzle section 4 from which liquid is sprayed out of the cylinder section by depressing the trigger section 13 with the handle section 12 gripped, wherein the handle section 12 has a finger contact portion S located posterior to a point of force of the trigger section 13.

    Abstract: A flexible pouch assembly includes a flexible pouch with a front panel and a back panel with a spray fitment sealed between the front panel and the back panel. The spray fitment may include a base portion with an aperture providing a fluid passageway between the flexible pouch and a head portion of the spray fitment for which product may flow through and be sprayed from a spray nozzle of the spray fitment. The base portion may have a canoe shape that provides a smooth transition for a top or upper seam of the flexible pouch thereby ensuring a leak-tight seal between the flexible pouch and the spray fitment.

    Abstract: A precompression system for a liquid dispensing device is presented, that prevents liquid from being discharged until a predetermined pressure has been built up. The system comprises a pump for drawing liquid through an inlet and discharging it through an outlet, and a precompression valve disposed between the pump and the outlet. The valve allows liquid in the pump to reach the outlet once the predetermined pressure is established, and stops liquid from reaching the outlet once the pressure falls below it. The precompression valve comprises an elastic diaphragm normally closing the valve opening, with a concave surface facing the valve opening and in fluid communication with the pump and a convex surface in fluid communication with atmospheric pressure. The diaphragm may be stretched around a valve seat. Methods of assembling such a precompression system in a dispensing device are also presented.

    Abstract translation: 提出了一种用于液体分配装置的预压系统,其防止液体排出直到预定压力被建立。 该系统包括用于通过入口抽出液体并通过出口排出的泵和设置在泵和出口之间的预压阀。 一旦建立了预定的压力,阀就允许泵中的液体到达出口,一旦压力降到其下方,液体便不能到达出口。 预压阀包括通常关闭阀开口的弹性膜片,凹面朝向阀开口并与泵流体连通并且与大气压力流体连通的凸面。 隔膜可以围绕阀座拉伸。 还给出了在分配装置中组装这种预压系统的方法。
