Liquid dispensing systems with gas removal and sensing capabilities
A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel.
1. A dispensing apparatus comprising:
a connector including a connector body having a lower portion connectable to a closure of a pressure dispense package, a downwardly extending probe portion, a liquid extraction conduit extending through the connector body and the probe portion and terminating at a lower end of the probe portion, a gas extraction conduit extending through the connector body and the probe portion and terminating at a location above the liquid extraction conduit;
a fitment; and
a fitment adapter received within the fitment and having a cup-shaped outer portion and a male inner portion received in the cup-shaped inner portion, the male inner portion having a gas passage and defining a longitudinal bore extending along a first axis, the longitudinal bore having an upper portion configured to receive the downwardly extending probe portion of the connector and a lower portion configured to receive an upper portion of a dip tub therein, wherein when the downwardly extending probe of the connector is received in the fitment adapter, the gas passage of the fitment adapter is in fluid communication with the gas extraction conduit of the connector.
2. The dispensing apparatus of claim 1 , wherein the gas passage extends along a second axis that is perpendicular to the first axis of the longitudinal bore defined by the inner portion.
3. The dispensing apparatus of claim 1 , wherein the gas extraction conduit is separate and distinct from the liquid extraction conduit.
4. The dispensing apparatus of claim 1 , wherein the connector further comprises a gas outlet port in fluid communication with the gas extraction conduit and a liquid outlet port in fluid communication with the liquid extraction conduit.
5. The dispending apparatus of claim 1 , wherein the connector further comprises a pressurization gas conduit for introducing a pressurization gas through the connector into a space between a liner and an overpack of a pressure dispense package when the connector is coupled to the closure of the pressure dispense package.
6. The dispending apparatus of claim 1 , further comprising a dip tube inserted into the lower portion of the longitudinal bore defined by the male portion of the fitment adapter.
