Abstract: In an example, a supply retainer may include a carton having a spout opening extending to a base edge of the carton. The spout opening may receive a spout of a supply bladder, in some implementations. The supply retainer may also include a retention clip having a retention opening extending to a leading edge of the retention clip to receive and retain the spout. The retention clip may also include a carton slot to slidably engage with a dividing wall of the carton so as to align the spout opening and the retention opening such that the spout may extend through the spout opening and the retention opening.

Abstract: A printing agent container and a method for manufacturing printing agent containers is disclosed wherein the container has improved stability to external collision. The container comprises a receptacle having at least one side wall and a bottom surface defining an internal volume; a cap on a top surface of the receptacle; and a tube connected to the cap and defining a fluid connection between the internal volume and the cap, wherein the receptacle comprises a protrusion that is provided, at least partially, in the bottom surface, and that extends into the internal volume, defining a bottom feed region between the protrusion and a side wall and wherein the tube extends at least partially in the feed region.

Abstract: In one example in accordance with the present disclosure, a sealing system is described. The sealing system includes a flexible ring (104). The flexible ring has a first surface (214) having radial grooves (218-1) formed therein to seal against a first mating member (108) and a second surface (216) having radial grooves (218-2) formed therein to interface against a foam ring (106). The sealing system also includes the foam ring. The foam ring has a first surface to interface against the second surface of the flexible ring and a second surface to seal against a second mating member.
