The present application is directed to a mixing device configured to mix, process or blend foodstuff and, more particularly, to a mixing device, blender or other such kitchen appliance that includes a jar for containing foodstuff and at least one travel mug for containing foodstuff, wherein the jar and the at least one travel mug are separately removably mountable to the base for blending and storage purposes.
Mixing devices or blenders are a relatively common household or kitchen appliance that are used to blend foodstuff, typically drinks or other foodstuff that is blended into a semi-fluid state. A typical blender includes a base enclosing a motor, a jar removably mounted to the base for containing the foodstuff and a lid to enclose the foodstuff within the jar. More recently, it has become popular to provide jars of various size and shape to accommodate a users needs in blending a variety of foodstuff. For example, certain blender bases, as seen in the food services industry, accommodate relatively large jars to blend large amounts of foodstuff at one time. Other types of blenders bases accommodate relatively small or portable containers or cups, such as a travel mug, to blend smaller amounts of foodstuff for individual or portable use. However, problems arise when the size and shape of the jar makes it difficult to efficiently and evenly blend foodstuff within the jar. For example, because of the relatively large or odd shapes of blending jars, unblended or partially blended foodstuff may become lodged or trapped in a part of the jar separate from the blending blades within the jar. Thus, the foodstuff within the jar may either be unevenly blended or hardly blended at all.
Therefore, it would be desirable to create a blender having two separate and independent motors that may operatively engage two separate and independent sets of blending blades within the interior of the jar of the blender to assure that all of the foodstuff within the blender is evenly and quickly blended. It would be desirable to create an interior surface of the jar that maintains a quantity of foodstuff over the set or sets of blending blades and that urges blended foodstuff towards a dispensing spout of a jar to improve evacuation of blended foodstuff from within the jar. Further, it would be desirable that the two independent and separate motors are capable of being controlled by the actuation of just one control knob on the outer surface of the blender base.
Another problem with conventional blenders is that users must purchase a number of different blender bases to accommodate the various sizes and shapes of jars. Therefore, it would be desirable to create a blender having a base that may operatively engage a variety of different sized and shaped jars such that a user would only need to purchase one blender base for use with a variety of different blender jars. It would be advantageous if smaller sized jars could fit within larger sized jars when the blender is not in use to reduce the overall size of the blender for storage purposes. Further, it would be desirable if the universal blending base included a mechanism to detect or recognize a specific type of jar. For example, if a user decided to use a relatively large jar, it would be desirable that the universal base could recognize that a large jar is in use such that both of the motors within the base would be actuated by just a single control knob when the mechanism detects the specific or particular type of jar on the base of the blender.
Briefly stated, the present invention is directed to a mixing device configured to blend foodstuff. The device includes a base housing at least one motor and a jar for containing the foodstuff. The device has a first operating configuration wherein the foodstuff is blended within the jar. The device further includes at least one travel mug for containing the foodstuff. The device has a second operating configuration wherein the foodstuff is mixed within the at least one travel mug. The jar and the at least one travel mug are separately removably mountable to the base. The at least one travel mug is removably mountable within the jar for storage.
In another aspect, the present invention is directed to a mixing device configured to blend foodstuff. The device includes a base having first and second motors capable of being separately operable by first and second control knobs, respectively. The base further includes a jar sensor. The device further includes a jar removably mountable to the base for containing the foodstuff. The jar sensor detects a presence of the jar on the base to enable actuation of each of the motors with the input of either the first control knob or the second control knob.
In yet another aspect, the present invention is directed to a mixing device configured to blend foodstuff. The device includes a base housing a first and a second motor. A jar for containing the foodstuff has a first set of blending blades and a second set of blending blades spaced apart from said first set of blending blades within an interior of the jar to blend the foodstuff. The first set of blending blades are operatively connected to the first motor and the second set of blending blades are operatively connected to the second motor when the jar is mounted to the base. A ramp is positioned between the first and second set of blending blades within the interior of the jar to maintain a quantity of foodstuff over the first and second set of blending blades.

The mixing device 10 has a first operating configuration (
As seen in
Preferably, the at least one motor 16, 18 is comprised of a first motor 16 and a second motor 18 capable of being separately operable by a first control knob 26 and a second control knob 28. However, it is understood by those skilled in the art that the mixing device 10 may include more than two motors without departing from the spirit and scope of the present invention. The first and second control knobs 26, 28, which are conventional control knobs as known to those skilled in the art, extend beyond the outer housing 11 of the base 14 and allow the user to control the operation and speed of the first and second motors 16, 18. The base support 12 may include a series of feet (not shown) comprised of an elastomeric or other non-skid, shock absorbing material for providing stability to the mixing device.
The base 14 includes a generally ovular recessed area 80 in a top surface to receive and operatively engage the jar 20 and/or the at least one travel mug 22, 24. As seen in

Two blending collars 21a, 21b are removably mountable within the lower end 20b of the jar 20 to enclose the lower end 20b of the jar 20. The blending collars 21a, 21b maybe removably mountable on to the jar 20 in virtually any manner, such as by threaded engagement, adhesion, magnetism or by friction-fitting, without departing from the spirit and scope of the present invention. A first set of blending blades 46a extends from the top surface of the first blending collar 21a and a second set of blending blades 46b extends from the top surface of the second blending collar 21b. A conventional clutch (not shown) extends from the bottom surface of each blending collar 21a, 21b to matingly engage with the corresponding base clutches of the recessed area 80. Preferably, the two sets of blending blades 46a, 46b extend into the interior of the jar 20 when the collars 21a, 21b are removably mounted to the lower end 20b of the jar 20. The two sets of blending blades 46a, 46b include blades of varying size and shape to blend the foodstuff within the jar 20 as efficiently and as quickly as possible. Thus, the two sets of blending blades 46a, 46b are positioned in a spaced apart manner within an interior of the jar 20 when the blending blades 46a, 46b are positioned within the lower end 20b of the jar 20. When the jar 20 is positioned on the base 14, the first set of blending blades 46a is operatively connected to the first motor 16 and the second set of blending blades 46b is operatively connected to the second motor 18.

The dispensing spout 40 further includes a dispensing handle 42 secured to said valve 58 for moving the valve 58 between the first and second positions. As seen in
Although the dispensing spout 42 of the present application is preferably permanently mounted to the dispensing tube 84 of the jar 20, it is understood by those skilled in the art that the dispensing spout 40 may be removably mounted to the dispensing tube 84. The dispensing spout 40 may include a fastening mechanism (not shown) that mates with locking keys (not shown) on the exterior periphery of the dispensing tube 84 which extends from the jar 20. Alternatively, the dispensing spout 42 may be threadingly engagable to the dispensing tube 84 (see

Although the use of one or two travel mugs is presently preferred, it is understood by those skilled in the art that the mixing device 10 may accommodate more than two travel mugs without departing from the spirit and scope of the present invention. The travel mugs 22, 24 are adapted for being transported with the user in a drinking configuration and for mounting to the base 14 of the mixing device 10 in a blending configuration (
Each travel mug 22, 24 preferably includes a drinking cap 22a, 24a that is removably mounted to the top of the cup body. The drinking caps 22a, 24a are preferably circular when viewed from above and formed to engage the circular top of the cup body 14. It is understood by those skilled in the art that the present application is not limited to the specific structure described above for the travel mugs 22, 24. Virtually any portable container or cup may be used to be removably mountable to the base 14 of the mixing device 10. Preferably, as shown in
In operation, the user places the base 14 onto the support surface, such as the countertop or tabletop, so that the base support 12 is flush with the support surface to provide stability to the mixing device 10. Next, the user operatively connects the power cord of the base 14 to an electrical outlet in a conventional manner. At this point, the user has the option of using the relatively large container (i.e. the jar 20) or the at least one smaller container (i.e. the at least one travel mug 22, 24). If the user desires that the blending operation requires the relatively large jar 20, the user mounts the blending collars 21a, 21b into the lower open end 20b of the jar 20 in a manner as described in detail above. Once the lower end 20b of the jar 20 is enclosed by the blending collars 21a, 21b, the jar 20 can be mounted within the recess 80 of the blender 14 to operatively connect the conventional clutches of the blending collars 21a, 21b to the clutches extending upwardly from the recess 80 of the base 14. The conventional clutches of the blending collars 21a, 21b and the clutches of the recess 80 matingly engage to ensure that the blending blades 46a, 46b can be properly controlled by operation of the first and second motors 16, 18.
Next, the user must ensure that the dispensing handle 42 of the dispensing spout 40 is in the closed position (
During operation of the motors 16, 18 in the present configuration, the ramp 52 within the jar 20 assures that the foodstuff is being efficiently and evenly blended. When the user determines that the foodstuff has been blended to a proper consistency, the user can pivot the dispensing handle 42 to the open position (
Alternatively, if the user determines that a smaller amount of foodstuff will be blended, the user may choose to blend foodstuff within either or both of the travel mugs 22, 24. In this configuration, the users will mount the blending collars 21a, 21b to the lower ends of the travel mugs 22, 24, respectively, as was described above. Once each blending collar 21a, 21b is properly attached to a travel mug 22, 24, the user would set the combined travel mugs 22, 24 and blending collars 21a, 21b onto the top of the base 14 such that the conventional clutches on the bottom of the blending collars 21a, 21b matingly engage the clutches within the recess 80 of the base 14. In this configuration, since the jar sensor 30 would not detect the presence of the jar 20, each motor 16, 18 must be separately and independently operated by its respective control switch 26, 28.
Once the user determines that the foodstuff within the travel mugs 22, 24 has been properly blended, the user rotates the control switches 26, 28 to cut power to the motors 16, 18, respectively. Then, the user would vertically remove each travel mug 22, 24 from within the recess 80 of the base 14. Next, each travel mug 22, 24 may be inverted such that the blending collars 21a, 21b can be removed from the bottoms of the travel mugs 22, 24. It is important for the user to check that the drinking cap 22a, 24a of each travel mug 22, 24, properly enclose the upper open end 20a of the cup bodies before the user inverts the travel mugs 22, 24. The user then removes the blending collars 21a, 21b from the travel mugs 22, 24 and encloses the lower open end 20b of the cup bodies with a cup base (not shown), as is known by those of ordinary skill in the art. Then, the travel mugs 22, 24 may be inverted once again into the normal upright position and may be carried or transported by the user or consumer.
It will be appreciated by those skilled in the art that changes could be made to the embodiment described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiment disclosed, but is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
