A hollow expansion chamber of the present invention is configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, where a chamber body of the expansion chamber has an oblate spheroid shape. When moving circumferentially downward along the chamber body starting from a maximum inside diameter, the oblate spheroidal shape of a bottom portion has a first integral transition that is a tangential transition to a first frustoconical shape. Continuing moving circumferentially downward, the first frustoconical shape has a second integral transition to a cylindrical extension. The cylindrical extension at a distal end has a bottom opening configured to fit within an opened bottleneck. The first frustoconical shape has a minimum angle of 15 degrees relative to a horizontal plane. The second integral transition is a radial second integral transition having an inside surface radius of at least 0.25 inches.

An assembly for a portable blender. The assembly having a housing that is configured for coupling to a container. The assembly has at least one battery, a motor electrically connected to the battery, a blade coupled to the motor, and a user input device operable to cause power to be sent from the battery to the motor so that the motor rotates the blade. At least a portion of the blade is positioned outside of the housing so that the blade is configured to be positioned in an interior space of the container when the housing is coupled to the container. The assembly may include a plurality of batteries each positioned radially outward from the motor with the batteries positioned circumferentially around the motor. A portable blender including the assembly and a container. The container having a dual-wall, vacuum insulated construction.

A drink mixer apparatus for easily mixing beverages includes a handle having a handle proximal end, a handle distal end, a handle left side, a handle right side, a handle top side, and a handle bottom side. A battery is coupled within the handle. A motor is coupled within the handle and is in operational communication with the battery. A trigger is coupled to the handle and is in operational communication with the motor. An extension arm is coupled to the handle. The extension arm is coupled to the handle distal end and bends to form an angle between 45°-90°. A mixer shaft is rotatably coupled to the extension arm. A drive line is coupled to the motor and extends through the extension to be in operational communication with the mixer shaft. A mixer paddle is coupled to the mixer shaft.

The present invention relates to a milk frother assembly which makes the two stirrers rotate forward and reverse respectively, by using the reversing drive mechanism, rotating rod one, rotating rod two, a carabiner and two stirrers, so as to achieve the advantage of more efficient milk frothing and controlling of the quality of milk bubbles. The assembly allows through its novel setting of the length adjustment mechanism, to manually slide the slide plate, then move the rotating rod two through the sleeve and the connecting rod, and then adjust the position of the inner stirrer head, which is suitable for making milk froth in various capacities.

A portable aerator comprising: a main aeration body; a base portion; an internal cavity; at least one ventilation shaft; a spout portion; an aeration opening; and an aeration inlet. The internal cavity comprises a threaded channel and cavity extends from a base portion opening to a spout portion opening. The internal cavity is configured to pass a liquid, such as wine that enters the internal cavity body at the base opening out through the spout portion opening. The threaded channel is threaded on an interior surface, such that the threaded channel is configured to matingly engage and disengage with a worm of a corkscrew bottle opening device, such as a waiter's wine key, via twisting and untwisting, respectively. The aerator device may have at least one ventilation shaft, an aeration shaft, and/or an extension tube.

The present invention is a dust shield device that secures over a mixing pail. Powdery material, such as plaster, cement, grout or the like, is poured through the device, and mixed with water inside the pail. The device includes a mounting sleeve, a radial manifold housing and a funnel shaped lid. The manifold housing and lid form a radial pneumatic channel with a circumferentially disbursed air intake that generates a radially uniform airflow that draws in airborne dust that would otherwise escape to the surrounding air. The manifold is connected to a vacuum with an air filter, and generates a dust shield zone and air intake zone above the device. The manifold lid forms a radial guard to prevent downward flows of material and water from entering the manifold, and forms a splash guard to retain upwardly projected splashes of material and water inside the pail.

A mixing and delivery system includes a compressible tube and a mixing apparatus. The compressible tube includes a reservoir configured for mixing and holding a surgical substance, an inlet portion for accommodating introduction of an element of the surgical substance into the compressible tube, and an exit port for enabling the delivery of the surgical substance to a target portion of an anatomy. The mixing apparatus is configured to be received through the inlet portion of the compressible tube for mixing elements of the surgical substance to form the surgical substance.

A mixed beverage product includes a container defining an interior chamber, an agitator mechanism coupled to the container, and a beverage contained in the inner chamber in the container. The beverage may be a coffee beverage, or the beverage may be carbonated water and a base beverage, such as fruit juice, veggie juice, or coffee. The agitator is configured to aerate the coffee beverage to form a foam layer on the coffee beverage, or to mix the carbonated water with the base beverage to form a foam layer on the beverage.

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 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.
