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.

A bioplastic collapsible dispensing tube may include a collapsible tube having walls that include a bioplastic material; a distal end of the tube that is sealed; a proximal end of the tube, opposite the distal end, that has an opening; a nozzle on the opening; and a closure for the nozzle; wherein, when the closure is opened and the tube is collapsed, flowable material inside the tube is urged out of the nozzle; and the bioplastic material includes a bio resin selected from the group consisting of PEF, PBF, PTF, GPE, GPET, PLA, PDLA, PLLA, PHA, and PHBH. A method may include forming a tube and filling the tube with flowable material from the distal end.

A container for packaging a pre-portioned amount of liquid or dry product is provided that includes a one-piece outer casing defining an interior reservoir. The outer casing has a cylindrical shell that is closed at one end by a rounded tip and open at the opposing end with an open circular outer edge/rim defining a mouth. To fill the container, the product is introduced through the mouth into the interior reservoir; then opposing edges of the rim are compressed together and sealed with heat to create an elongated seal having two opposing ends. Multiple types of elongated seals are provided. In one aspect the outer casing is formed unitarily of a plastic resin. To open the container, the consumer squeezes the two opposing seal ends/termini toward each other; this deforms the elongated seal and causes the seal to snap open, which allows access to the product.

A container with multi-chambers is described. Each hair coloring substance of the multi-chamber is stored in its sub-chamber. The final hair coloring solution is formed by mixing the hair coloring substances in mixing sub-chambers in liquid communication with the interior of each of the sub-chambers. An optional mixing nozzle is also used in conjunction with the mixing chamber, and the mixing nozzle may include a helical mixing tool.
