Abstract
There is provided an infant feeding bottle system having an agitator for mixing a powder substance with a liquid in a non-rigid disposable liner. The bottle system permits a user to mix powdered formula directly inside a non-rigid liner. The bottle system enhances the mixing effect, resulting in improved solubility, and provides for a self-contained uninterrupted mixing and feeding process.
Claims25
An agitator for mixing components in a container having an open end with an inner diameter, the agitator comprising:
- an annular wall forming a hole having a longitudinal axis, said annular wall having a first outer diameter, said annular wall having at least a portion that is tapered towards said longitudinal axis;
- at least one spoke being secured to said annular wall and traversing said hole;
- and
- a retaining flange being secured to said annular wall and having a second outer diameter,
- wherein said first outer diameter is smaller than said second outer diameter, wherein said first outer diameter is about equal to said inner diameter thereby allowing said annular wall to at least partially slide into said open end, and wherein said second outer diameter is larger than said inner diameter thereby preventing said retaining flange from sliding into said open end.

A container assembly for mixing components comprising:
- a container having an inner volume and an open end with an inner diameter;
- an agitator having an annular wall with a first outer diameter, at least one spoke, and a retaining flange with a second outer diameter, said annular wall defining a hole with a longitudinal axis, said annular wall having at least a portion that is tapered towards said longitudinal axis, said at least one spoke being secured to and traversing said hole, said retaining flange being secured to said annular wall;
- a dispensing mechanism;
- and
- a fastening ring,
- wherein said annular wall is at least partially disposed through said open end of said container and in said inner volume, wherein said first outer diameter is smaller than said second outer diameter, wherein said first outer diameter is smaller than said inner diameter thereby allowing said annular wall to at least partially fit into said open end, and wherein said second outer diameter is larger than said inner diameter thereby preventing said retaining flange from fitting into said open end of said container.
