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.

A trigger sprayer having a venting system including a piston bore and a vent bore at least partially contained therein, the vent bore including at least one vent port; a piston and vent piston are moveably seated in the piston bore and vent bore, respectfully, the vent piston including at least one annular seal and a vent path port, the vent path port and vent port in gaseous communication when the vent piston is actuated and moved over the vent port.

A dispenser, which has a pump chamber formed by a body including a depression, and a lid body covering an opening of the body, where a liquid in the pump chamber is discharged front a nozzle portion by performing a discharge operation that presses the lid body toward an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber when the discharge operation is released. A coil spring that urges the lid body to an outside of the pump chamber is included in the pump chamber, a diameter of the coil spring is larger than a radius of the lid body, and a deformation amount of the lid body is equal to or more than ⅓ of a diameter of the lid body.

A new all-plastic micro miniaturized spray gun. Inner hole of miniaturized spray gun piston bush includes lower elastic sleeve; upper and lower ends of piston cavity in inlet hole of body include upper and lower thru-hole; upper elastic sleeve disposed above inner hole of piston bush in inlet hole on body between upper and lower thru-hole; upper elastic sleeve abutted against piston bush and fixed in inlet hole of body; diversion groove is disposed on inner walls of inlet hole on body; which is tapered and corresponds to upper elastic sleeve; which includes piston and cover; lower thru-hole of body is normally open; when upper thru-hole of body drives piston to move inwardly through wrench, lower elastic sleeve is stressed subject to pressure change, controlling opening or closure of inlet hole on body, and upper elastic sleeve is deformed subject to pressure change, opening or closing upper thru-hole of body.

A trigger sprayer having a venting system including a piston bore and a vent bore at least partially contained therein, the vent bore including at least one vent port; a piston and vent piston are moveably seated in the piston bore and vent bore, respectfully, the vent piston including at least one annular seal and a vent path port, the vent path port and vent port in gaseous communication when the vent piston is actuated and moved over the vent port.

The present invention is a device and method for dispensing liquids in glass containers. The invention can be used to spray liquids from non-threaded glass containers that do not typically otherwise have a mechanism for spraying. Furthermore, this allows the user of the liquid to use the original container and avoid transferring the liquid from the original container. An adapter is fitted into the neck of an appropriate glass container, such as an olive oil bottle, and a sprayer may be threaded onto the adapter.

A handheld comminutor—spray bottle assembly includes a bottle; a comminutor; and a sprayer assembly. The bottle has an externally threaded mouth. The comminutor includes a comminutor body, with an internally threaded rim, housing a power source and an electrically connected motor. Blades connected to the motor by a shaft extend from the comminutor body. The sprayer assembly includes a spray head attached to a spray bottle cap, a siphon straw and an elongated filter housing connected with a spray head inlet, with a filter on the housing. A filter housing cap secures the filter to the housing. The spray bottle cap has an internally threaded rim and a seal ring. The comminutor rim and the spray bottle cap rim alternately connect with the mouth of the bottle. The motor rotates the shaft and the blades. Biomatter and liquid comminuted in the bottle are dispensed using the spray head.

The invention relates to a device for dosing liquid from a liquid-receiving element (2), in which the liquid-receiving element (2) comprises an outlet valve (1), and a dosing system is available, said dosing system consisting of a first actuating wing (4) and a second actuating wing (5), which are arranged around the liquid-receiving element (2) and can be moved in relation to each other such that they compress the liquid-receiving element (2), a mechanical dosing stop being available.

A dispenser, which has a pump chamber formed by a body including a depression, and a lid body covering an opening of the body, where a liquid in the pump chamber is discharged from a nozzle portion by performing a discharge operation that presses the lid body to an inside of the pump chamber to deform the lid body, and a liquid is caused to flow into the pump chamber by releasing the discharge operation. The dispenser includes a pressing support portion disposed to face the lid body, and a discharge operation is performed by pinching a top portion of the lid body and the pressing support portion with fingers from lateral sides of the body.

An exemplary tabletop foam sanitizer dispenser includes a bottle comprising a reservoir for containing liquid sanitizer. The bottle has a base for sitting on a surface. The base has a base diameter. The bottle has a top and a neck located proximate the top having an opening. The opening has an inner neck diameter. The base diameter is at least 3 times the inner neck diameter. A pump assembly is also included. The pump assembly has a cylindrical housing. The cylindrical housing having an outer housing diameter. The outer housing diameter is less than the inner neck diameter. The cylindrical housing is inserted into the bottle through the neck opening. A pump is located in the cylindrical housing. The pump includes a liquid inlet, an air inlet, a liquid outlet and an air outlet. A pump is motor located in the cylindrical housing. A battery is also located in the cylindrical housing. A nozzle housing is located above the cylindrical housing. A liquid and air mixing chamber located in the outlet nozzle housing. The liquid and air mixing chamber is in fluid communication with the liquid outlet and the air outlet. An outlet nozzle is in fluid communication with the mixing chamber and is located in a lower portion of the nozzle housing. The table top dispenser further includes a sensor for detecting a hand of a user positioned below the nozzle.
