Embodiments described herein relate to articles and methods for forming liquid surface films on the interior surfaces of containers for holding one or more products comprising one or more Bingham plastic materials. Bingham plastic materials behave as a solid under no or low shear stress, and behave as viscous liquids when an applied shear stress exceeds a yield stress. In some embodiments, a container for containing a product includes an interior surface and a liquid disposed on the interior surface. Before introduction of a product into a container, the liquid may be surrounded by air. The liquid-air interface in contact with the interior surface makes a contact angle, .sub.os(a), with respect to the interior surface of the container, of about 0. After a product has been introduced to the container, the liquid is at least partially covered by the product. The liquid-product interface in contact with the interior surface, makes a contact angle, .sub.os(p), with respect to the interior surface, of less about 60. The subscript o denotes the liquid, subscript s denotes the interior surface, subscript a denotes air, and subscript p denotes a product. In some embodiments, the contact angle .sub.os(p) can be less than about 50, less than about 40, or less than about 30.

Improvements in an agitator is disclosed. The agitator has a central body with sides that have blades that flex or bend inward upon insertion and then expand once the pass through the neck of the bottle. The side are elongated and allows the mixer to have an orientation within the bottle. The orientation allows for a buoyancy of the mixer to break-up powder or fruit that typically floats on the surface of the liquid. The side elements can cut into fruit and pulverize power to blend the ingredient(s). A carrier or case for the mixer provides a container for the mixer to dry and further collects and water from the mixer. A removal hook allows a user to snag one of the ends or a side element. The side flexing elements of the mixer will bend inward to pass the mixer out the neck of the bottle.

A bottle includes a base, neck that defines an aperture, and a body. The bottle has at least one indent in the body that projects into an interior of the bottle and extends around at least part of a circumference of the body. This at least one indent is configured to agitate a substance contained in the bottle. For example, the bottle may contain a powder, such as protein powder, and the at least one indent helps mix the powder with a liquid. In an example, two indents are used in the bottle.

An apparatus and method are provided for storing and dispensing into a liquid a soluble substance, such as a flavoring, a body fuel, a nutritional supplement, a stimulant, a relaxant, an alcohol neutralizer, or a medical drug. A useful application of the subject invention includes a lime flavoring held by a gelatinous artificial lime wedge stored with a beer bottle or can, or attached to a 6-pack or 12-pack carton. The artificial lime wedge may be retrieved from a protective covering and acted upon so it mixes the lime flavoring into the beer when it is inserted into the beer bottle or can. Rather than needing to buy and store a perishable natural lime, and cut it up, an artificial lime wedge may be stored for an extended period of time with a beer vessel and placed in functional contact with the beer at time of consumption.

The tumbler bottle includes a cup having a side wall interior surface and bottom wall a convex interior surface. The cup side wall and bottom wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a first mixing chamber. The tumbler bottle further includes a lid, removably connected with the cup. The lid includes a side wall interior surface and a top wall concave interior surface. The lid side wall and top wall interior surfaces are joined by a smooth, arcuate interior transition surface to define a second mixing chamber. The lid further includes a dispensing outlet and a closure. When coupled together the first mixing chamber and the second mixing chamber are in fluid communication and are configured to uniformly mix a liquid with one or more additives.
