Description

AN AGITATOR FOR A FOOD MIXER
CROSS-REFERENCE TO RELATED APPLICATION This is a continuation-in-part of our prior, co- pending application, Serial No. 896,400 filed August 14, 1986.
TECHNICAL FIELD
This invention relates to an agitator for a food mixer, such as a mixer of the type which will blend candy or other condiments into ice cream, milk shakes or the like. More particularly, this invention relates to an agitator blade which is disposable insuring sanitary conditions without having to clean the agitator between usages.
BACKGROUND ART For many years mixers with agitator shafts extending downwardly have been used to mix food items, such as milk shakes, right in a cup. More recently, similar mixers have been used to mix solid food chunks, such as candy and the like, into soft serve ice cream and other foods of similar texture. Since such mixers have permanent agitator shafts, frequent cleaning, most often between each use, is required because it is highly likely that each user will be blending different materials. Such cleaning is quite time consuming for the commercial establishment which blends the product for the customer and is virtually impossible for the commercial establishment which invites the customer to blend his own product.
To date no one has developed an agitator assembly for such mixers which will not be in need of this frequent cleaning. ,
DISCLOSURE OF THE INVENTION It is thus a primary object of the present invention to provide a disposable agitator for a food mixing device. It is another object of the present invention to provide an agitator, as above, which can be readily utilized by the consumer himself.
It is a further object of the present invention to provide an agitator, as above, which is in the shape of a spoon so that the consumer can utilize the same as a utensil to eat the food product.
It is still another object of the present inven¬ tion to provide an agitator, as above, in which the bowl of the spoon is axially offset from the shaft thereof to increase mixing action.
These and other objects of the present invention, which will become apparent from the description to follow, are accomplished by the improvements hereinafter described and claimed.
In general, a disposable agitator is designed for engagement with a rotatable shaft having coupling means associated therewith. The agitator has a hollow stem adapted to fit over and rotate with the shaft, there being an agitator blade on the end of the stem. The stem is provided with means to engage the coupling means of the shaft to position the stem longitudinally on the shaft.

PREFERRED EMBODIMENTS FOR CARRYING OUT THE INVENTION
A conventional mixer 10 is shown schematically in Fig. 1 and includes a rotatable shaft 11 which carries the disposable agitator indicated generally by the numeral 12. Mixer 10 is equipped with a motor which, when activated by switch 13, rotates shaft 11 and agitator 12. Positioning a cup of ice cream or the like, mixed with candy or other condiments, so that agitator 12 is in the ice cream results in a smooth blended product when shaft 11 is rotated.
One embodiment of shaft 11 is shown in detail in Fig. 2 as having an annular recess 14 near the top thereof and having a flat end 15 at the bottom thereof. As will hereinafter be described, recess 14 and flat end 15 serve as devices which enable coupling of shaft 11 to agitator 12 to prevent longitudinal and rotational movement of agitator 12 with respect to shaft 11. Shaft 11 can be constructed out of any durable material, such as stainless steel, and while it is shown as being somewhat tapered, it can take on an essentially cylindrical shape if desired.
The embodiment of agitator 12 used with the embodiment of shaft 11 shown in Fig. 2 is best shown in Fig. 3 and is preferably made of an inexpensive material, such as many common plastics, so that it can be economically discarded after use. Agitator 12 includes a hollow sleeve stem portion 16 at one end and an agitator blade portion 17 at the other end. Stem 16 is shown as being tapered to correspond to the taper shown for shaft 11 although it will be appreciated that if shaft 11 were not tapered, stem 16 would also not be tapered but would rather correspond in 5 configuration to that of shaft 11.
An annular detent 18 is provided internally of stem 16 near the top thereof for locking engagement with recess 14 of shaft 11 to secure agitator 12 longitudinally of shaft 11. A lug 19 is provided internally near the
10 bottom of stem 16 generally at the point where stem 16 connects with blade 17. Lug 19 makes a dog-like engagement with flat 15 of shaft 11 so that agitator 12 will rotate with shaft 11 in a non-slip fashion.
While blade 17 could take the form of any well
• known agitating type configurations, it is shown as being in the shape of the bowl of a spoon having reinforcing webs 20 to strengthen the transition between stem 16 and blade 17. •Being so configured as a spoon, the agitator can serve the additional function of enabling the consumer to use it as a
20 utensil for eating the product.
It should also be noted that the center of gravity of blade 17 is shown as being axially offset from the centerline of shaft 11 and stem 16 which has been found to enhance the agitating action. However, a blade 17 in line
2 with the axis of rotation of shaft 11 could be constructed without departing from the spirit of this invention.
From the above description it should be appreci¬ ated that the disposable agitator 12 can be readily attached to shaft 11 by sliding the sleeve stem 16 over
30 shaft 11 until detent 18 snaps into recess 14. Upon rotation of shaft 11, flat end 15 will engage lug 19 and the sleeve stem 16 will rotate with the shaft so that blade 17 will mix the product in a cup held by the user. After completion of the mixing process, agitator 12 can be removed ^ and discarded or, if blade 17 is in the form of a spoon, as shown, it can be utilized as a utensil by the user to consume the product. It should be appreciated that during the mixing process, sleeve stem 16 has protected shaft 11 from contact with the product and therefore no cleaning of shaft 11 is necessary preparatory to the next use.
Another embodiment of a rotatable shaft is shown ' in Fig. 6 and identified generally by the numeral HA.
Shaft HA has an upper cylindrical portion 21 attachable to the drive mechanism of mixer 10 and a lower portion 22 designed to receive the alternate embodiment of the agitator indicated generally by the numeral 12A in Fig. 7. An annular flange 23 is provided at the junction of portions 21 and 22 of shaft HA which, as will hereinafter be described in more detail, enables the coupling of shaft HA to agitator 12A to prevent longitudinal movement of agitator 12A with respect to shaft HA. Shaft HA, like shaft 11, is normally constructed of a durable material, such as stain¬ less steel, with lower portion 22 of shaft HA being generally square in configuration, and while it is shown as being tapered, such is not critical to the spirit of this invention.
Agitator 12A, like agitator 12, is preferably made of an inexpensive plastic material and includes a hollow sleeve stem portion 24 at one end and an agitator blade portion 25 at the other end. Blade portion 25 can be essentially identical to blade portion 17 of Fig. 3, that is, in the shape of a bowl of a spoon so as to serve the additional function of an eating utensil. Stem 24 is shown as being square in cross-section to conform with lower portion 22 of shaft HA and likewise, if desired, can be tapered, as shown. Stem 24 will thus rotate with shaft HA.
The upper end of stem 24 of agitator 12A is provided with a collar 26 which mates with flange 23 of shaft HA. A clip member indicated generally by the numeral 27 in Fig. 7 includes a resilient shank portion 28 extending outwardly from stem 24 of agitator 12A and terminating at its upper end as a barb portion 29. Barb 29 engages flange 23 to secure agitator 12A longitudinally of shaft HA. Thus, disposable agitator 12A can be readily attached to shaft HA by sliding the hollow sleeve stem 24 over lower portion 22 of shaft HA. As barb 29 passes upwardly over flange 23, shank portion 28 of clip 27 will flex outwardly until barb 29 is above flange 23 at which time shank portion 28 will snap inwardly so that barb 29 engages flange 23 and longitudinally locks agitator 12A to shaft HA. The user can then conduct the mixing process in the identical manner and with the same advantages as described with respect to the embodiment shown in Figs. 2-5. From the foregoing it should be evident that a disposable agitator constructed as described herein will accomplish the objects of the present invention and other¬ wise substantially improve the food mixing art.
