Abstract: The invention discloses an all-plastic spray device, comprising a handle, an environmentally friendly cross-arm plastic spring, a positioning seat, a nozzle mechanism, a hexagonal plug, a piston mechanism, an environmentally friendly plastic upper spring, an environmentally friendly plastic lower spring, a plastic ball, and a pump body. The invention adopts the design of two-stage elastic element. Both the environmentally friendly plastic upper spring and the environmentally friendly plastic lower spring are made of plastic materials, which can well replace the metal spring. The two-stage elastic element also has a significant improvement in the pressing feel. In addition to being suitable for conventional liquid use, it is also very suitable for the use of solutions that are prone to corrosion with metal parts. The invention greatly facilitates people's daily use and maintains life, health and safety in people's daily use.

Abstract: A method of assembling a trigger sprayer assembly includes providing an engine having a piston chamber and a fluid passage that is fluidly coupled to the piston chamber, the fluid passage extending from an input portion to an output portion. The method further includes inserting a piston component into the piston chamber, and coupling a trigger lever to the engine and the piston component. Pivoting the trigger lever relative to the engine pushes and pulls the piston component within the piston chamber to drive fluid from the input portion to the output portion of the fluid passage. The method further includes coupling a shroud to the engine, where the coupling comprises positioning a rail protrusion of the engine within a corresponding recess formed in the shroud, and inserting a shelf extending from an interior surface of the shroud into a pair of receiving clips extending from the engine.

Abstract: Dispensing devices are provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. An example dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve. Liquid exiting the piston chamber under pressure enters a central vertical channel which is in fluid communication with both the pressure chamber and a dome valve, with pre-defined opening pressure, provided near the outlet channel at the top of the dispensing head.

Abstract: [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
the S valve structure A is formed of a spring portion 1 and a valve piston portion 2 drooping from the spring portion 1, and the valve piston portion 2 includes a core rod portion 21, an outer skirt portion 22 extending downward from an outer circumference of the core rod portion 21 and an inner skirt portion 23 longer than the outer skirt portion 22.-
