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.

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 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 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 the 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 patent application relates to an arrangement for a packaging of a dual liquid component, which comprises a first component and a second component, the arrangement for the packaging that includes a container and an auxiliary device for application of the dual liquid component product. The container may have an upper, tubular part having a frustum-shape, and a lower part. The upper, tubular part may comprise an upper neck, in which the auxiliary device for application of the dual component product is assembled, and an upper wall with an open base, the upper wall being fitted with internal stops located internally near the neck and a seat located internally near the open base. The open base may host a sealing ring with an internal thread. The lower part may store the second component and may comprises a bottom, a lower wall, an upper free end fitted with an external thread and an adjacent seat strip located under the external thread.

A liquid dispenser, having a large ring, a connecting cover, and a hollow pump frame, the pump frame is movably clamped to the interior of the large ring, the top of the pump frame extends to the outer side of the top of the large circle, a bottom protruding portion of the connecting cover extends into a top groove of the pump frame so as to be movably clamped thereto, a first air outlet is provided on both sides of the bottom of the connecting cover, and a second air outlet in communication with the first air outlet is provided to penetrate through the pump frame. The first air outlet, the second air outlet, the first liquid outlet, and the second liquid outlet can be opened and closed by rotating the connecting cover to change a position relationship between the connecting cover and the pump frame.

An aerosol spray can has a can body, a valve assembly, a dip-tube assembly and a rigid tube. The valve assembly is mounted on the can body. The dip-tube assembly is connected to the valve assembly and has a head end channel-linked to the valve assembly. The dip-tube assembly has a flexible tube and a weight piece. The two ends of the flexible tube are connected to the valve assembly and the weight piece respectively. The rigid tube is sleeved around the flexible tube to constrain excessive bending of the flexible tube. The flexible tube protrudes from the rigid tube. The weight of the weight piece drives the tail end freely toward the ground. Therefore, the tail end stays submerged under a liquid product when less than a half of the liquid product is left inside the can body even when the can body is tilted or horizontal.

A trigger dispenser device (1) envisages a secondary liquid aspiration duct (50) in communication with the dispenser duct, and a primary liquid aspiration duct (8) in communication with the container, off-axis with each other. Between these, a joining compartment (64) is provided communicating upstream with the primary liquid aspiration duct (8) and communicating downstream with the secondary liquid aspiration duct (50) to form the fluidic connection between them. In particular, the container (C) is of the type with built-in suction pipe.

An arrangement for activating an aerosol dispenser having a conveying tube for conveying a liquid; a movable holding member holding the conveying tube; a rotatable base; and a container chamber between the holding member and the base, wherein the arrangement is configured to transmit a loading rotation of the base to a substantially axial loading movement of the holding member towards the base, and wherein the holding member has a locking structure exposed to the container chamber. An aerosol dispenser having the arrangement and a method for activating an aerosol dispenser are also provided.
