Abstract
A integral beverage stirrer which incorporates the pitcher and a hand driven geared stirrer assembly in which the geared mechanism is mounted inside the lid of the pitcher.
ABSTRACT
In a beverage pitcher and stirrer, it has been proposed to provide a internal direct drive stirrer device to mix directly into the pitcher any beverage. In this invention the stirrer device is a integral stirrer assembly, hand driven through a geared mechanism of two gear wheels mounted and being part and parcel of the lid. The stirrer assembly is composed of the gear wheel mechanism, the rotating shaft and the mixing element. The geared mechanism is composed of a small gear wheel, interlocked with the top end of the shaft, and of a larger internal gear wheel attached to the lid. The rotating shaft is supported at the bottom center of the pitcher and is driven by the gear wheel mechanism incorporated in the lid. The mixing element is a multiple blade screw type propeller attached to the bottom section of the rotating shaft. Additionally the outside body of the internal gear wheel is used to hand drive the stirrer assembly and the lid is particularly designed to totally enclose the gear wheel mechanism. When the handle is activated, the rotating motion transmitted by the gear wheel mechanism is increased approximately six times and is transmitted by the shaft to the mixing element.

Description
SPECIFICATION
This invention is an integral beverage stirrer which incorporates the pitcher and a hand driven geared stirrer assembly in which the gear wheel mechanism is mounted inside the lid of the pitcher. This invention is used to mix beverages, particularly those which have a natural tendency to decant such as frozen concentrated juices.
It is common to agitate a juice container to ~ounteract the decanting tendency. This action tend to spill some residual liquid from previous use or from lack of hermetic sealing.
It is also common to stir the contents with a spoon or another device which is more time consuming and requires cleaning. Those are obviously not desirable. It has hitherto heen proposed to provide a beverage pitcher with an internal stirrer device,reference in this connection being made to, for example, U.S. Patent No. 4,893,940 which issued on Jan 16, 1990 to Stephen L. Waisberg.
Unfortunately the direct drive system described does not provide fast and efficient mixing results.
I have found that these disadvantages may be overcome by providing the beverage pitcher with a internal geared stirrer assembly to greatly increase the speed of the mixing element. The high rotating speed combined with the multiple blade screw type propeller produce a quick whirlpool effect which rapidly transforms the liguid solution into a homogeneous beverage.
In drawings which illustrate embodiments of the invention :
Fig.1 :is a cross section view of the integral beverage stirrer assembly.
Fig.2 :is a cross section view of the lid Fig.3 :is a cross section view of the combined handle and driving internal gear wheel.
Fig.4 :is a cross section view of the mixing element and of the small gear wheel which is interlocked with the top end shaft.

When fully disassembled, the beverage stirrer assembly comprises only five pieces, all of which are made of hard plastic. The pitcher, the lid, the combined driving handle and internal gear wheel, the shaft with the mixing element, and the small gear wheel.
Referring to the drawings, numerals designate like parts in the several figures with particular reference to the embodiment shown in Fig.1, pitcher 10, comprises cylindrical side walls 11 and the lower end is closed by a base wall 12. 13 denotes a pouring spout which is provided in the upper portion of cylindr:ical wall 11, and 14 denotes a handle attached to upper cylindrical wall 11 and diamatrically opposite pouring spout 13.
With particular reference to the embodiment shown in Fig.1 and Fig.2 , 20 denotes a lid for the pitcher 10. The downwardly extending skirt portion 21 of lid 20 is friction fitted on the outside of the upper end portion of cylindrical ~all 11. The skirt portion 21 has two slots to provide an opening space for spout 13 and handle 14.
The cover lid has an off center circular opening 22, which comprisas an upstanding small side wall 23 in a Eorm of a cylindrical wall. The lower end of which is closed by a base wall 24. In the center of lid 20 out oE base wall 24 a downwardly projecting center boss 25 is used to support shaft 40. 26 is a center hole in relation to opening 22 in base wall 24 used to secure the internal gear wheel to the lid. Opening 22 provides a space to contain the gear wheel mechanism in which base wall 24 is used to support the internal gear wheel 30.
~ ith particular reference to the embodiment shown in Fig.1, Fig.2 and Fig.3, the driving internal gear wheel 30 fits directly into opening ~2. Inside and in the center o the internal gear wheel 3~, the downwardly extending small shaft 31, is used to secure the internal gear 30 through hole 26 to lid 20 by means of a snap flange type attachment 32. 33 denotes a circular shaped handle used to hand drive the gear wheel mechanism and 34 denotes the teeth of internal gear wheel 30.
With particular reference to the embodiment shown in Fig.1, Fig.2 and Fig.4, 40 denotes the main shaft supported by center boss 25 of lid 20. The bottom end of shaft 4n is laterally restrained in a conical integral boss 15 extending upwardly from the middle bottom wall 12 of pitcher 10. A
multiple blade screw type propeller 41, is permanently attached to the bottom end section of main shaft 40. A
small gear wheel 42 is interlocked to main shaft 40.
2 ~
When fully assembled the integral beverage stirrer is composed of two major subassemblies. The first one is the pitcher and the second is the lid with the enclosed gear wheel mechanism, the main shaft and the mixing element.
When ready to use, a quick 1/3 turn rotation o~ the driving handle will through the gear wheel mechanism, rotate the mixing element rapidly two full rotations. This e~fortless action will instantaneousl~ mix the beverage without spilling or splashing. A alternative way of using the stirrer is by rotating the handle back and ~orth. Although the gear wheel mechanism is well enclosed in the lid and should not get in contact with the beverage, the stirrer assembly can be easily fully disassembled i~ cleaning is still required. This is provided by the intarnal gear wheel being snap attached to the lid and by the small gear being interlocked to the main shaft.
