Abstract
An apparatus for dispersing additive into a fluid stream is disclosed. Also disclosed are systems comprising a fluid handling apparatus and an additive pod configured to disperse additive into a fluid stream. In some embodiments, the additive pods are easy to install into an outlet portion of a fluid handling apparatus, and do not require special training or the use of tools.
Claims17
An apparatus for introducing additive into a fluid stream comprising
- an additive pod comprising at least one sidewall defining an additive holding chamber and at least one depressible engagement tab extending from the at least one sidewall that is flared at an angle to a longitudinal axis of the additive pod, the engagement tab having a distal portion configured to cooperatively engage with at least one receiving member on an outlet portion of a fluid handling apparatus;
- at least one additive disposed in the additive holding chamber, wherein the additive holding chamber is configured to disperse the additive into the fluid stream and wherein the additive holding chamber is configured to be disposed in an outlet portion of the fluid handling apparatus,
- wherein the additive pod has a first at least partially open axial end, a second at least partially open axial end, and the sidewall is a closed wall extending between the first at least partially open axial end and the second partially open axial end that allows fluid to flow into the additive pod along its longitudinal axis and allows fluid to exit the additive pod along its longitudinal axis.
An apparatus for introducing an additive into a fluid stream comprising
- an additive pod comprising at least one sidewall defining an additive holding chamber and at least one depressible engagement tab extending from the at least one sidewall that is flared at an angle to a longitudinal axis of the additive pod, the engagement tab having a distal portion configured to cooperatively engage with at least one receiving member on an outlet portion of a fluid handling apparatus, wherein at least a portion of the at least one sidewall is porous;
- at least one additive disposed in the additive holding chamber, wherein the additive holding chamber is configured to disperse the additive into the fluid stream and wherein the additive holding chamber is configured to be disposed in an outlet portion of a fluid handling apparatus;
- wherein the additive pod further comprises:
- at least one upstream sealing member configured to form a seal with the outlet portion of the fluid handling apparatus;
- at least one downstream sealing member configured to form a seal with a downstream article.

A system for introducing an additive into a fluid stream comprising
- a filter cartridge having a housing and an outlet portion, wherein an outlet flow stream exits the housing through the outlet portion;
- an additive pod comprising at least one sidewall defining an additive holding chamber and at least one depressible engagement tab extending from the at least one sidewall that is flared at an angle to a longitudinal axis of the additive pod, the engagement tab having a distal portion configured to cooperatively engage with at least one receiving member on an outlet portion of a fluid handing apparatus,
- wherein the additive pod has a first at least partially open axial end, a second at least partially open axial end, and the sidewall is a closed wall extending between the first at least partially open axial end and the second partially open axial end that allows fluid to flow into the additive pod along its longitudinal axis and allows fluid to exit the additive pod along its longitudinal axis;
- at least one additive disposed in the additive holding chamber, wherein the additive holding chamber is configured to disperse the additive into the fluid stream;
- wherein the additive holding chamber is configured to be disposed in the outlet portion of the filter cartridge.
