The present invention relates generally to a mixer, such as a blender. More particularly, the present invention relates to a mixer with interchangeable container bases, one including a faucet.
Blenders have been developed to mix ingredients or food items, such as beverages. For example, ice and fruit and other ingredients can be disposed in the blender and mixed together by rotating blades. It is often difficult to pour the mixed ingredients through the top of the blender due to the viscous nature of the mixture, and the larger size of the blender with respect to the cup or glass.
Smoothie makers have been developed that include a faucet or spout through which the smoothie or mixed ingredients can be dispensed to resist spilling and to facilitate dispensing. In some situations, however, it may be desired to mix ingredients, such as with a smoothie maker, but not necessarily to use the faucet or spout. Using the smoothie maker, however, usually necessitates cleaning the faucet or spout. If it is considered undesirable to clean the faucet or spout, then a blender can be used, thus requiring the user to own both a blender and a smoothie maker.
It has been recognized that it would be advantageous to develop a mixer that can be used for both blender and smoothie activities, and can selectively provide a faucet when desired, but not require a faucet.
Briefly, and in general terms, the invention is directed to a food mixer device with interchangeable container bases to selectively provide a faucet when desired. The interchangeable container bases can be separately and removably couplable to a container. At least one mixing assembly can be rotatably disposed in the container. A faucet is operatively coupled to one of the interchangeable container bases.
The invention is also directed to a method for mixing food. The method includes deciding whether to dispense the food through a faucet on a container, or pour the food from a top of the container. One of at least two interchangeable container bases is releasably coupled to the container. The two interchangeable container bases include a first container base with a faucet, and a second container base without a faucet. Ingredients are introduced into the container. The ingredients are mixed in the container with a mixing assembly in the container. The food is dispensed through the faucet of the first interchangeable container base, or poured through the top of the container with the second interchangeable container base thereon.
Additional features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of the invention; and, wherein:

As illustrated in
The food mixer 10 can include a container or jar 14 disposable over or associated with a mixer base or housing 18. The container 14 can be removably disposed over the mixer base 18, and thus can be removed from the mixer base 18 for cleaning, etc., while the mixer base can include electrical components, motors, and the like. The mixer base 18 can include a motor 22 (
A receptacle or socket 30 (
The container 14 can include a handle 36 to facilitate grasping and manipulating the container. The handle 36 can be positioned or oriented on a lateral side with respect to the mixer base 18 to facilitate being grasped by a user. Thus, the receptacle or perimeter wall can facilitate orienting the handle 36 with respect to the mixer base.
The container 14 can include or be associated with a mixing assembly 38a or 38b that can include one or more blades 42a or 42b rotatably disposed in the container 14, or near a bottom of the container. The mixing assembly 38a or b can be engaged by the drive mechanism 26 of the mixer base 18 when the container 14 is disposed over the mixer base 18, or over the receptacle 30. For example, the drive mechanism 26 and the mixing assembly 38a or b can include mating or matching couplings, such as one or more intermeshing protrusions and indentations, so that the rotation and force of the motor 22 in the base can be transferred to the mixing assembly 38a or b or blades 42a or b in the container 14.
The container 14 can be a hollow shell with an annular wall to receive ingredients therein. In one aspect, the container 14 can include a container portion or shell or wall that can be transparent or translucent, or formed of a transparent or translucent material, to enable viewing the contents of the container 14. The container portion or shell or wall can be glass, and the handle also can be formed of glass. Alternatively, the container can be formed of plastic. A top of the shell or container 14 can be open to receive ingredients therethrough, while the bottom of the shell can be open to receive the mixing assembly 38, or so that the mixing assembly 38 or blades 42 can operatively engage the contents of the container 14. A chute 46 can be formed in the top of the shell or container 14 to facilitate pouring through a top of the container. As stated above and described below, the container 14 can include a container base(s) to close off the bottom of the container 14 and retain the mixing assembly 38a or b. The container base(s) can form a portion of the container, and the mixing assembly can be wholly or partially disposed in the container base(s). The container base(s) can receive the bottom portion of the container or shell to enclose the bottom of the container 14, and can be removable for cleaning.
At least two interchangeable container bases can be provided, including a first container base 50 and a second container base 54. The first container base 50 can include a faucet 58 (or spigot or spout) to facilitate dispensing of the contents of the container (
In addition, the first container base 50 can include a first mixing assembly 38a with first blades 42a, while the second container base 54 can include a second mixing assembly 38b with second blades 42b. The first blades 42a (associated with the first container base 50 and the faucet 58) can be thicker and configured to chop ice. The second blades 42b (associated with the second container base 54) can the thinner, and configured for chopping. For example, the second blades 42b can be serrated. Thus, the interchangeable container bases 50 and 54 can selectively provide a faucet 58, and appropriate blades.

A cap or plug 146 can be selectively disposed in the opening 142 to resist contents from exiting the container during mixing. The cap or plug 146 can be formed of a hard or rigid plastic, and can form a resistance fit or press fit with the lid. Alternatively, the cap or plug can be twisted in the opening and tabs and slots can be formed between the cap or plug and the opening to selectively lock and unlock the cap by twisting. The cap or plug 146 can be disposed in the lid in the configuration without the faucet, as shown in
In addition, a stir stick 150 can be carried by the lid 134 and can extend through the opening 142. The lid 134 can include a chamfer or bevel around the opening 142 to form a socket to receive a bulbous or ball portion 154 (
Controls or a control panel with buttons 158 for controlling the operation of the motor 18 also can be disposed on the mixer base 18, and can define a front of the mixer base. As is known in the art, the controls or buttons 158 can be electrically coupled to the motor to control its operation. The buttons 158 can include an on/off button, speed control, etc.
In addition, the food mixer 10 can include a food processing or chopping function or add-on. Referring to
In use, one of the interchangeable container bases 50 and 52 can be selectively coupled to the container 14. A user can decide whether to dispense the food or contents of the container through the faucet 58 on the container, or pour the food or contents from the chute 46 at the top of the container. If it is desired to pour the contents through the chute at the top, then the second container base 54, without a faucet, can be coupled to the container 14, as shown in
The container base 50 or 54 and container can be disposed on the mixing base 18. The mixing assembly can engage the motor carried by the mixing base. The first container base 50 can be oriented with respect to the mixing base 18 so that the faucet 58 is disposed on the lateral side with respect to the mixing base.
Ingredients can be introduced into the container 14 through the top. The lid 134 can be removed and ingredients introduced into the container. Alternatively, the cap 146 or stir stick 150 can be removed and the ingredients can be introduced through the aperture 142 in the lid. The cap 146 can be disposed in the lid 134 when the second container base 54, without the faucet, is used, while the stir stick 150 can be carried by the lid 134 when the first container base 50 is used. It is understood that the cap and stir stick can be used in either configuration, or with either container base.
The ingredients can be mixed in the container with the mixing assembly 38a or b or blades 42a or b. The buttons 158 on the mixing base 18 can be utilized to control the motor and the mixing. The stir stick 150 can be pivoted in the aperture 142 to facilitate mixing.
If the first container base 50 is used, the food or contents can be dispensed through the faucet 58. A cup or glass can be disposed on the lateral side of the mixing base and the valve or handle selectively operated to selectively open and close the faucet, and dispense contents through the faucet. The mixing assembly and motor can be operated during dispensing to facilitate dispensing of the contents. It will be appreciated that the turning of the mixing assembly or blades can direct contents out through the faucet. In addition, the contents can be diverted as they rotate in the container by a flow diversion protrusion extending inwardly from the wall of the container base proximate the outlet aperture. If the second container base 54 is used, the food or contents can be poured through the top of the container, or through the chute.
In addition, the user can decide to chop food. Thus, the third and different container base 218 can be removably disposed on the mixing base 18. Ingredients can be introduced into the different container 214, such as through the chute. The ingredients can be chopped in the different container 214 with at least one chopping blade 222, rotatably disposed in the different container.
Various aspects of beverage mixers are set forth in U.S. Pat. No. 6,527,433 and U.S. patent application Ser. No. 10/278,713, which are herein incorporated by reference.
The present invention also provides a faucet for use with a glass container or goblet. The container base 50 can form an adaptor to couple a faucet to the glass container. The container base 50 can be formed of plastic, such as by injection molding. Limitations in glass blowing or manufacturing created difficulties in providing a glass goblet or container with a faucet. The container base 50 of the present invention, however, advantageously allows the use of both a glass container and a faucet. A method for providing a glass goblet with a faucet includes forming a container from glass with a lower opening with external screw threads, such as by glass blowing or other glass manufacturing technique. A faucet or an inlet thereof with internal screw threads can be formed, such as by injection molding. A container base can be formed from plastic, such as by injection molding. The container base can include an upper opening with internal screw threads; a lateral protrusion with a lateral opening and external screw threads; and a lower opening. The external screw threads of the lower opening of the container can be screwed into the internal screw threads of the upper opening of the container base. The internal screw threads of the spout can be screwed over the external threads of the lateral protrusion of the container base.
While the forgoing examples are illustrative of the principles of the present invention in one or more particular applications, it will be apparent to those of ordinary skill in the art that numerous modifications in form, usage and details of implementation can be made without the exercise of inventive faculty, and without departing from the principles and concepts of the invention. Accordingly, it is not intended that the invention be limited, except as by the claims set forth below.
