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.

         6 . The pump system of  claim 4 , further comprising a container and a dip tube in the container, wherein the container is connected to the valve body and a portion of the port of the dip tube connector is sealed against a portion of the dip tube adjacent the inlet of the port. 
     
     
         7 . The pump system of  claim 6 , wherein the port further comprises at least one seal sealed against the dip tube. 
     
     
         8 . A dispenser system, comprising:
 a container;   a container aperture in the top of the container;   a functional wall in the container;   an auxiliary liquid aspiration opening in the functional wall;   a dispenser head attached to the container relative to the container aperture, the dispenser head including a frame;   at least one connector in the frame;   an auxiliary body, comprising a collar attached with the at least one connector and retaining the auxiliary body with the frame; and   a duct formed between the frame and the auxiliary body.   
     
     
         9 . The dispenser system of  claim 8 , wherein the auxiliary body further comprises:
 an auxiliary body head, wherein the collar is positioned about a periphery of the auxiliary body head; and   a liquid aspiration duct extending off of the auxiliary body head, comprising a duct outlet in the auxiliary body head and a duct inlet in an end of the liquid aspiration duct opposite the auxiliary body head and seated in the auxiliary liquid aspiration opening.   
     
     
         10 . The dispenser system of  claim 9 , wherein at least a portion of the liquid aspiration duct adjacent the duct inlet is sealed against at least a portion of the functional wall. 
     
     
         11 . The dispenser system of  claim 8 , further comprising:
 an annular lip extending downward of the frame towards the container;   the annular lip providing a seal at a lower outer edge projecting from the annular lip; and   an annular groove in the auxiliary body, wherein the annular groove seals against the seal at the lower outer edge of the annular lip.   
     
     
         12 . A dispenser device for dispensing a liquid from a container, comprising:
 a dispenser head including a frame, the frame comprising:
 an annular lip extending downward of the frame; 
 the annular lip providing a seal at a lower outer edge thereof; and 
 a connector; 
   an auxiliary body comprising:
 a collar attached to the connector and attaching the auxiliary body to the frame; and 
 an annular groove sealed against the seal at the lower outer edge of the annular lip; and 
   a duct formed between the auxiliary body and the frame.   
     
     
         13 . The dispenser device of  claim 12 , further comprising:
 an auxiliary body head in the auxiliary body, wherein the collar is positioned on a periphery of the auxiliary body head; and   a liquid aspiration duct extending off of the auxiliary body head, comprising a duct outlet in the auxiliary body head and a duct inlet in an end of the liquid aspiration duct opposite the auxiliary body head.   
     
     
         14 . The dispenser device of  claim 13 , wherein the duct inlet is in communication with the duct formed between the auxiliary body and the frame.
