A trigger sprayer assembly for dispensing a fluid is provided. The assembly includes an engine having a piston chamber and an outlet passage that is fluidly coupled to the piston chamber, a piston having a plunger and an intermediate portion that extends from the plunger and terminates in an end portion, a trigger lever having a main body and a piston coupling body, and a pair of trigger springs coupled to the main body. Each trigger spring includes a first curved portion, a second curved portion, and a terminating portion. The terminating portions are configured to fit within recesses formed in the engine, and the piston coupling body engages with the end portion. Pivoting the trigger lever from a neutral position to an actuated position compresses the trigger springs and pushes the plunger into the piston chamber to drive fluid into the outlet passage.

A trigger sprayer assembly is provided. The assembly includes an engine having a piston chamber and a fluid passage that extends from an inlet portion to an outlet portion, a piston having a plunger that is disposed within the piston chamber, and a trigger lever that is configured to pivot between a neutral position and an actuated position. The assembly further includes an input valve and an output valve configured to control unidirectional fluid flow through the inlet and outlet portions of the fluid passage. The input valve includes a cylindrical body terminating in a flap portion. Pivotal movement of the trigger lever from the actuated position to the neutral position pulls the plunger out of the piston chamber such that the flap portion of the input valve pivots from a closed position to an opened position and fluid flows through the input valve and into the piston chamber.

A manually operated trigger sprayer that stores a quantity of pressurized liquid during the charge stroke of the trigger for subsequent release during the return stroke, is presented. The trigger sprayer is configured such that an appreciable volume of liquid is dispensed during both the charge and the return strokes of the trigger, creating a continuous discharge stream, for so long as the trigger is actuated. The present invention trigger sprayer also provides an all plastic construction by replacing tile metal coil spring of prior art trigger sprayers with a U-shaped plastic spring located exterior to the pump housing thereby making the trigger sprayer well-suited for recycling.

The present invention relates to a solid pressed air freshener and odor neutralizer composition which can include greater than 10% fragrance. The air freshener comprises a fragrance; preferably the fragrance is impregnated within a water soluble substrate made from a foamed vegetable starch, a surfactant and a solidifier. The solid formulations break down easily in the presence of water and may be sprayed, within the area to be freshened.

A pump system may include a blown-in dip tube connected to a valve body and having a connection which may include an improved blown-in dip tube connector having one or more of a lip for sealing with a blown-in dip tube, a seal ring configured to mate with a blown-in dip tube and seal therewith, a dip tube lock for mating with a blown-in dip tube, or an o-ring for providing an improved seal with a blown-in dip tube.

Provided is a dispensing head with a trigger for a dispensing device having a frame, a piston chamber, a piston, a dispensing duct, a suction duct, pre-compression valve means, suction valve means, and a nozzle assembly having a nozzle and a dual chamber foamer. The dispensing head is particularly effective for dispensing products with sanitizing and antimicrobial effect.

A spray pump formed to atomize and apply a viscous liquid may micro-discharge the viscous liquid ranging from low to high viscosity in a quantitative manner, may miniaturize a device capable of atomizing liquids by spraying, and may shorten a spraying path to prevent changes in liquid properties and keep spraying quality constant.

A fluid delivery system for dispensing fluid can include a dispenser, such as a trigger engine-type dispenser (100), configured to draw fluid up from a container. A nozzle assembly can include a nozzle (160), and a nozzle slide (112). The nozzle slide can be configured to slide and/or rotate relative to the shroud (102) to provide different dispensing modes. In alternative examples, the nozzle (160) can be configured to rotate in 30 degree increments relative to the shroud (102) to provide the different dispensing modes or the nozzle assembly can include a nozzle extension, and the nozzle extension can be configured to rotate relative to the shroud to provide different dispensing patterns out of the nozzle. In another example a first nozzle can be configured to provide one or more dispensing modes, and a second nozzle can be configured to provide a different dispensing mode than the first nozzle. Methods of dispensing fluids and methods of assembling fluid dispensers are also disclosed.

A dispensing closure system includes an upper closure portion and a lower closure portion including an axial flow conduit and a vent conduit. The upper closure portion is axially movable relative to lower closure portion between shipping and dispensing positions. A seal is disposed on the lower closure portion over the flow and vent conduits. A peripheral spacing strip is removably secured to the upper closure portion and engages with either the lower closure or the outside of the container to prevent movement. A piercing probe includes piercing elements in alignment with the flow and vent conduits for piercing the seal. In the shipping position, the piercing elements are spaced from the seal. However, when the spacing strip is removed and the upper closure portion is axially moved to the dispensing position, the piercing elements pierce the seal to open the flow conduit and the vent conduit.

A trigger-type liquid dispenser that, even when lateral force is applied to a trigger, prevents liquid leakage. The trigger-type liquid dispenser includes a pump, which includes: a cylinder, which includes an inner tubular wall and an outer tubular wall; a piston, which has a front-side end portion; a front-side sealing piece and a rear-side sealing piece; an outer-circumferential-side support portion; and an inner-circumferential-side support portion. The outer-circumferential-side support portion is provided with an annular cut-off portion, which forms a gap between the outer-circumferential-side support portion and an outer circumferential surface of the piston.
