Trigger Dispenser

Abstract

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.

What is claimed is: 
     
         1 . A pump system, comprising:
 a container having a dip tube;   a trigger sprayer having a vent connection extending from an interior portion of a piston chamber to an interior portion of a valve body and connected to the container; and   a dip tube connector connected to the trigger sprayer, comprising:   a connector head connected to the trigger sprayer;   a fluid inlet;   a fluid flow path between the fluid inlet and the connector head;   a seal member adjacent the fluid inlet and mated with the dip tube connector, providing a seal between the seal member and an interior surface of the dip tube; and   a vent passage connected to the vent connection.   
     
     
         2 . A pump system, comprising:
 a container having a dip tube;   a valve body connected to the container, comprising:   at least one connector; and   a vent connection;   a piston;   a trigger;   a spring;   a valve;   a dip tube connector, comprising:   a fluid inlet;   a connector head comprising at least one connector lip;   a fluid flow path between the fluid inlet and the connector head; and   a vent passage;   wherein the at least one connector lip is fit with the at least one connector of the valve body to retain the dip tube connector with the valve body and connect the vent passage to the vent connection.   
     
     
         3 . The pump system of  claim 2 , further comprising a product in the container. 
     
     
         4 . The pump system of  claim 2 , further comprising a nozzle in communication with the valve body. 
     
     
         5 . The pump system of  claim 2 , further comprising a shroud in communication with the valve body. 
     
     
         6 . A pump system, comprising:
 a container having a dip tube;   a trigger sprayer having a vent connection extending from an interior portion of a piston chamber to an interior portion of a valve body and connected to the container; and   a dip tube connector connected to the trigger sprayer, comprising:   a connector head connected to the trigger sprayer;   a fluid inlet;   a fluid flow path between the fluid inlet and the connector head; and   a vent passage connected to the vent connection.   
     
     
         7 . A dispenser device, comprising:
 a container having an auxiliary liquid aspiration duct;   a dispenser head having a secondary air aspiration duct extending from an interior portion of a pressure chamber to a frame and connected to the container; and   an auxiliary body connected to the dispenser head, comprising:
 a main portion connected to the dispenser head; 
 a liquid inlet; 
 a primary liquid aspiration duct between the liquid inlet and the main portion; 
 a flexible coupling portion adjacent the liquid inlet and mated with the auxiliary body, providing a seal between the flexible coupling portion and the auxiliary liquid aspiration duct; and 
 a primary air aspiration duct connected to the secondary air aspiration duct. 
   
     
     
         8 . A dispenser device, comprising:
 a container having an auxiliary liquid aspiration duct;   a frame connected to the container, comprising:
 a connector; and 
 a secondary air aspiration duct; 
   a piston;   a trigger;   an elastic return means;   a valve;   an auxiliary body, comprising:
 a liquid inlet; 
 a main portion comprising an annular collar; 
 a primary liquid aspiration duct between the liquid inlet and the main portion; and 
 a primary air aspiration duct; 
   wherein the annular collar is fit with the connector of the frame to retain the auxiliary body with the frame and connect the primary air aspiration duct to the secondary air aspiration duct.   
     
     
         9 . The dispenser device of  claim 8 , further comprising a liquid in the container. 
     
     
         10 . The dispenser device of  claim 8 , further comprising a nozzle in fluid communication with the frame. 
     
     
         11 . The dispenser device of  claim 8 , further comprising a shroud connected to the frame. 
     
     
         12 . A dispenser device, comprising:
 a container having an auxiliary liquid aspiration duct;   a dispenser head having a secondary air aspiration duct extending from an interior portion of a pressure chamber to a frame and connected to the container; and   an auxiliary body connected to the dispenser head, comprising:
 a main portion connected to the dispenser head; 
 a liquid inlet; 
 a primary liquid aspiration duct between the liquid inlet and the main portion; and 
 a primary air aspiration duct connected to the secondary air aspiration duct.
