Abstract

Bubble traps for removing bubbles from a stream of liquid and flexible containers comprising such bubble traps are disclosed. The bubble trap includes a containment chamber fluidly coupled to an outlet conduit. At least one grate is disposed between the containment chamber and the outlet conduit. The at least one grate includes a plurality of grate inlets formed in a grate wall and fluidly coupled to the outlet conduit with a plurality of grate conduits such that the containment chamber is fluidly coupled to the outlet conduit. The grate traps bubbles entrained in the stream of liquid flowing from the containment chamber to the outlet conduit in the containment chamber when the bubbles are greater than or equal to a diameter of the grate inlets.
