Abstract

Examples of the present disclosure relate to a base for a printing material container. The base has a channel structure defining an opening of the base, an axis of the channel structure defining an axial direction. The base also has a material-guiding structure, formed around the opening, having a helical lower surface that extends from the channel structure in the axial direction. An upper surface of the material-guiding structure is formed by a lower surface of the base and the helical lower surface meets the lower surface of the base at a curved side wall that extends radially from the channel structure to an annular portion of the base.
