Abstract
In some embodiments, apparatuses and methods provided herein are useful for dispensing a fluid, such as a thixotropic fluid. In some embodiments, a bottle having a closure cap includes a flip top, a base, and a disk, where the base and disk define a mixing chamber configured to facilitate mixing of any serum or liquid separated from the fluid back therein. In some configurations, the base has a central opening through which the fluid exits and an internal shaft with a non-planar end surface opposite the central opening. In some configurations, the non-planar end surface and the disk define channels between the mixing chamber and the internal shaft. In some embodiments, the disk includes a central opening, a plurality of partial annular openings through a planar surface of the disk, and projections extending into the mixing chamber.
