Abstract
Disclosed herein is a delivery device comprising a chamber; a gas inlet; a gas outlet; and a dip tube contained within the chamber and having an upper portion and a lower portion, the upper portion of the dip tube being in fluid communication with the gas inlet and being operative to permit the entry of a carrier gas; the lower portion of the dip tube extending into the chamber, the lower portion of the dip tube terminating in an outlet end; and a sleeve; where the sleeve has a first end and a second end; the first end being in an interference fit with the lower portion of the dip tube; and where the sleeve vibrates upon being subjected to a disturbance.
Claims16
A delivery device comprising:
- a chamber;
- a gas inlet;
- a gas outlet;
- and
- a dip tube contained within the chamber and having an upper portion and a lower portion, the upper portion of the dip tube being in fluid communication with the gas inlet and being operative to permit the entry of a carrier gas;
- the lower portion of the dip tube extending into the chamber, the lower portion of the dip tube terminating in an outlet end;
- and
- a sleeve;
- where the sleeve has a first end and a second end;
- the first end being in an interference fit with the lower portion of the dip tube;
- where the sleeve vibrates upon being subjected to a disturbance and where the sleeve comprises a metal having a wall-thickness of 0.020 to 0.070 millimeters or an elastomer that vibrates upon being subjected to a disturbance;
- where the sleeve has slots extending from the second end into the sleeve toward the first end and an interior end of the slots comprises a circular opening.
A method comprising:
- discharging through a dip tube, a carrier gas into a delivery device that comprises:
- a chamber;
- a gas inlet;
- a gas outlet;
- and
- a dip tube contained within the chamber and having an upper portion and a lower portion, the upper portion of the dip tube being in fluid communication with the gas inlet and being operative to permit the entry of a carrier gas;
- the lower portion of the dip tube extending into the chamber, the lower portion of the dip tube terminating in an outlet end;
- and
- a sleeve;
- where the sleeve has a first end and a second end;
- the first end being in an interference fit with the lower portion of the dip tube;
- where the sleeve vibrates upon being subjected to a disturbance and where the sleeve comprises a metal having a wall-thickness of 0.020 to 0.070 millimeters or an elastomer that vibrates upon being subjected to a disturbance;
- where the sleeve has slots extending from the second end into the sleeve toward the first end and an interior end of the slots comprises a circular opening;
- promoting vibration in the sleeve as the carrier is discharged from the perforated member;
- and
- transporting the carrier gas from the gas outlet to a site external to the delivery device.
