A device for mixing liquid material which a user shakes by hand up and down or left and right is provided. The device includes: a container that includes a space on an inner side extending in the longitudinal direction, and a grip shape on an outer side of the container; an opening-closing member; and a coil spring which has a constant winding diameter and moves freely inside the container in the longitudinal direction. Liquid material and the coil spring are contained in the container, the liquid material being obtained by mixing a material to be dispersed and liquid. A silencer is provided at the end of the coil spring. The device includes: a coil spring abutting part that abuts against and supports 80% of a planar spread formed by one winding of an end of the coil spring relative to the one winding; a first vertical wall and a second vertical wall which are two vertical walls which are perpendicular to the coil spring abutting part and also perpendicular to the coil constituting the coil spring, and are provided at limiting positions where the coil spring of the coil spring abutting part abuts; and a cylindrical wall that extends vertically opposite to the coil spring of the coil spring abutting part, and has an inner diameter set to be the outer diameter of the coil spring, wherein the first vertical wall and the second vertical wall each have two holes through which a coil constituting the coil spring can pass arranged side by side in a direction in which the coil spring extends.

The present invention relates to a shaker bottle device that has a body and a lid. The body is further preferably comprised of at least one measuring line that indicates a corresponding amount of liquid or solid volume that is within the body, wherein the line is further highly visible using contrasting colors, fiber-optic, fluorescent, or luminescent paint. The body may also be comprised of a weighted bottom surface that prevents the device from spilling. The body and lid may also have at least one magnet that allows the device to magnetically attach to a metal surface or object to further prevent spilling.

An agitator may include one or more members adjustable between an expanded configuration and a compressed configuration. When the one or more members are in the expanded configuration, the agitator in a first set of two orthogonal dimensions is larger than an opening having a predetermined size. When the one or more members are in the compressed configuration, the agitator in a second set of two orthogonal dimensions is smaller than the opening having the predetermined size. The one or more members are biased to the expanded configuration in absence of external force applied to the one or more members. In use, the agitator may be inserted into a container through a neck of the container in the compressed configuration. The agitator may expand within the container so that the container does not fit through the neck of the container.

The invention disclosed herein is a novel coil apparatus, system, and related method, useful for the mixing and agitation of a powdered substance into a liquid. The coil has features and is configured such that the edges of the coil can reach the inside corners of the bottle or container to provide improved mixing and cleaning of the container. Embodiments of the coil also terminate in a figure or logo that provides a way to mark or brand the product. When combined with a bottle, the system provides a way to store, mix, and clean baby formula, as well as entertain an infant by creating a rattling sound within the bottle.

A resealable package for mixing two or more components, comprising a base, walls that extend from said base, whereby said walls are joined to each other such that an overall volume is defined that is able to accept a quantity of fluid, a fluid solid or gas, a folding section that folds such that the overall volume of the package is reduced, and a resealable opening.

A new mixing device for mixing solids and medium- to highly viscous food ingredients with liquid in a shaker bottle. The mixing device has a generally dumbbell-shaped agitator insertable within a hand-held, shakeable container. The agitator is composed of a framework arranged to provide voids to allow for flow of liquids, powders, and other materials into and out of portions of the generally dumbbell-shaped agitator. The mixing device also has a weighted member attached adjacent to or within the center of the generally dumbbell-shaped agitator that increases the momentum of the mixing device when in operation.

A shaker device can include a cap configured to be resiliently fit around at least a portion of a container to seal an opening of the container and to engage the cap to the container to hold the cap to the container. The shaker device can include a mixing stalk attached to the cap and configured to hang into the container when the cap is sealing the opening of the container.

A beverage container has a body with an open top, an interior volume and a closed bottom. A lid assembly is removably coupled to the open top of the body. A storage compartment is removably coupled to the closed bottom of the body. A mixer is coupled to the lid assembly. The mixer can mix contents located inside the body. The mixer can be silent when a user of the beverage container shakes contents located inside the body.
