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.

A multi-phase cosmetic composition mixing pack for mixing immiscible components of a multi-phase cosmetic composition such that they are temporarily miscible includes a container for holding the multi-phase cosmetic composition that has a first open end and a container longitudinal axis, and a mixing element disposed within the container and configured to be actuated for mixing immiscible components of the multi-phase cosmetic composition such that they are temporarily miscible, wherein the mixing element is limited to movement substantially along the container longitudinal axis when actuated.

EZE CHEF is a device a transparent plastic sheath that when placed over a bottle will measure ingredient levels to insure perfect recipe presentations of finished food entrees is disclosed. My invention improves on others by allowing a user to change the size of the mixing vessel without changing the ratio between ingredients and still come out with the same perfect end result.

A baby feeding container contains a bottle, a whisking ball, a sealing ring, and a liquid outlet. The whisking ball is positioned within the bottle. The liquid outlet is pressed against an opening of the bottle with the sealing ring. The liquid outlet includes a nipple collar and a feeding nipple that ensure the liquid within the bottle flows out of the feeding nipple. If the user intends on measuring the amount of liquid within the bottle, a plurality of quantity markers can be used. Moreover, the whisking ball is insulated in a rubberized coating to minimize any noise generated when the baby formula is mixed in water by shaking the bottle.

A continuous mixer/reactor and a mixing process are provided in which materials flow in an orderly fashion along the length of a channel (9) and the materials are mixed in a direction transverse to the axis of the channel (9) by the provision of agitator elements (5, 7) within the channel (9) and shaking the channel (9) so that the agitator elements (5, 7) move within the channel (9) in the radial direction of the channel (9).

A new mixing device for mixing solids and medium to highly viscous food ingredients with liquid in a shaker bottle. The mixing device has an agitator with a center portion and distal portions of larger diameter than the center portion. The agitator is 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 agitator. The mixing device also has a weighted member attached adjacent to or within the center of the agitator that increases the momentum of the mixing device when in operation. The weighted member may have a metal core and polymer exterior.

A liquid eyeliner pen includes a barrel, an accommodating cavity is formed in the barrel, the barrel is connected with a liquid delivery assembly, an end of the liquid delivery assembly is in communication with the accommodating cavity, the barrel is connected with a cap configured for covering the liquid delivery assembly, a stirring element with a stirring end is slidably connected in the accommodating cavity, and the stirring end is located at a dead corner.
