A container system for liquids, including an in-container mixer/aerator in the exit throat of the container. The mixer/aerator is a cylinder, having axial peripheral grooves, and and axial central bore, divided by axial vanes.

An apparatus includes a body having a length extending from a first end to a second end. The body defines a bore extending through the entirety of the body and at least one of a plurality of grooves or holes around the bore. The body has a length that is dimensioned to be received entirely within a neck of a container.

Applicator apparatus can include a circumferential wall and a support arm movably mounted relative to the circumferential wall. The support arm can include a protrusion extending in an axial direction within an interior passage of the circumferential wall. Methods of assembling the apparatus are provided in further embodiments. Methods of introducing an additive are provided in further embodiments. In further embodiments, a mouth fill device can include a circumferential shroud. In some embodiments, a plurality of apertures can be disposed in a circumferential lip circumscribing an end of the circumferential shroud. In further embodiments, a protrusion can be mounted relative to the circumferential shroud. In further embodiments, a collapsible container or a collapsed container can include a first shell, a second shell, and a circumferential bladder that can have a higher axial collapsibility than both the first shell and the second shell.

A cup assembly for holding touch-up paint is disclosed herein. The cup assembly includes a cup portion with a fluid reservoir configured to hold a volume of touch-up paint; a lid portion configured to matingly engage with the cup portion in a substantially airtight manner so as to prevent the volume of touch-up paint from solidifying; and a shaker ball disposed inside the fluid reservoir of the cup portion, the shaker ball configured to agitate the volume of touch-up paint in the fluid reservoir. A method of applying touch-up paint, which utilizes the cup assembly, is also disclosed herein.
