[Summary] [Object] To provide an S valve structure to be incorporated in an accumulator spray with a reduced pulling force of a trigger portion E. [Solution] The present invention is directed to an S valve structure A in an accumulator spray to be attached to a container to suction liquid in the container from an introduction tube H via an F valve into a main cylinder portion, apply pressure to the liquid in the main cylinder and, when the pressure exceeds a certain pressure, eject the liquid via an S valve structure A from a nozzle portion F wherein

S valve structure for accumulator spray

[Object] To provide a trigger-type pump dispenser that makes it possible to prevent an out-of-nozzle squirting phenomenon that occurs at a final stage of sucking up of liquid out of a vessel into a cylinder. [Solution] A trigger-type pump dispenser A includes a handle structurea nozzle base structureattached to the handle structurea triggera cylinder structurea capby which the cylinder structureis held down and attached to the mouth of a vessel, a piston structurethat slides inside the cylinder structurean inverted-mortar-shaped lipformed in the piston structurea springthat springs the piston structurea valve caseattached to the nozzle base structurea mortar-shaped valve seatformed in the valve casea leak valveattached to a bottom part of the cylinder structurethat has a bulging portionat a tip thereof, a first valve FV, and a second valve SV. A movement of the piston structurefrom top dead center to bottom dead center causes liquid in the cylinder structureto be discharged from a nozzle orifice N. The bulging portionat the tip of the leak valveis disposed to pass through the inverted-mortar-shaped lipA through-hole diameter Dof the mortar-shaped valve seatof the valve caseis smaller than a nozzle orifice diameter D

Trigger-type pump dispenser

A pressurized spray A is provided with a cap part, a body partcapable of being attached to the cap part, a base bodythat is attached to the body part, an introduction pipefor introducing a liquid in a container attached to the base body, a nozzle partattached to the body part, a cylinder partattached to the body part, an F valveattached to the bottom of the cylinder part, a piston partthat is allowed to slide inside the cylinder part, a pivotal triggerthat moves the piston partin forward and backward directions, a restoring spring partfor restoring the trigger, a pressurized valve (S valve) attached to a passage of the body part, and a pressing spring partfor pressing the pressurized valve in a valve closing direction, and by pivotally moving the trigger, the pressurized spray A jets out the liquid, and a liquid passagethat communicates with the inside of the cylinder partis formed between the base bodyand the body partso that the liquid located between the pressurized valve and the base bodyis collected in the container through the liquid passageand the introduction pipe

Pressurized sprayer

To provide a base body of pressurized spray that makes it possible to stabilize a pressing spring and also to reduce the number of assembling processes. The base body, which is assembled into a pressurized spray A that is attached to a container so as to suck a liquid inside the container into a cylinder partthrough an F valvefrom an introduction pipe, and by applying a pressure to the liquid inside the cylinder, the liquid is jetted out through an S valvefrom a nozzle, is provided with: an attaching part for use in attaching the introduction pipeon a lower side, which is attached between a cap and a container mouth part, and a pressing spring partthat is attached onto an upper side and presses the S valvein a valve closing direction.
