Definitions

• This invention relates to a food processing machine of the type which utilizes a mixing blade to blend food products in a container. More particularly, this invention relates to the manner in which the cover of the container is attached to and detached from the container, and the manner in which hot food products can be safely dispensed from the container. In addition, this invention relates to the manner in which the motor which rotates the blade is protected from moisture.
• Most food processing equipment that blends foods in a container by means of a rotating blade includes a cover for the container.
• Such covers must be securely attached to the container during the mixing of the foods, and yet, at the same time, be removable without requiring undo force.
• Some prior art covers are made of a flexible material and include a slot which receives a lip of the container thereby holding the cover on the container. In some of these covers, a tab extends from the cover and is lifted to release the cover from the container. However, after multiple flexures, this release system of the prior art tends to breakdown such that the tab becomes overflexed resulting in the inability of the cover to latch onto the container.
• a food processing assembly made in accordance with one aspect of the present invention includes a container having a base surface and at least one sidewall extending upwardly from the base surface and forming an open top.
• a spout is formed on the sidewall near the open top and a handle is formed on the sidewall generally opposed to the spout.
• a heat shield is attached to a portion of the sidewall generally at the location of the spout.
• a food processing assembly in accordance with another aspect of the invention, includes a container having a peripheral rim near an upper open surface. A cover is provided to close the upper open surface, the cover having at least one tab assembly.
• the tab assembly includes a body portion having a notch to engage the rim and a handle portion extending upwardly from the body portion. Upon upward movement of the handle portion, the rim will come out of the notch to release the cover from the container.
• Yet another aspect of the invention relates to a food processing assembly which includes a container and a base member adapted to carry the container. Air intake openings are formed in the base member and a gutter is provided to prevent liquid from being received by the openings.

• Fig. 10 is a rear elevational view of the base member.
• Fig. 11 is a partially sectioned side elevational view of the base member.
• a food processing assembly is shown in Fig. 1 and is generally indicated by the numeral 20.
• Assembly 20 includes three basic component parts, a base member indicated generally by the numeral 21 , a blender container indicated generally by the numeral 22, and a cover for the container 21 indicated generally by the numeral 23.
• Base member 21 is provided with feet 24 and includes a motor housing portion generally indicated by the numeral 25 and a platform portion generally indicated by the numeral 26.
• Housing portion 25 includes a top wall 27, opposed front and rear walls, 28 and 29 respectively, and opposed side walls 30 which together with a bottom surface (not shown) house a motor.
• One of the side walls 30 is provided with a recess 31 which can receive any of several controls such as a circuit breaker 32, a master power switch 33 or the 5 like. Because these controls are recessed, they are protected from accidental contact.
• the rear wall 29 of housing portion 25 may be provided with an opening 34 for the passage of a power cord for the motor.
• Rear wall 29 is also provided with a plurality of air intake slots or louvers 35.
• Ao fan in housing portion 25 draws cooling air into housing portion 25 through louvers 35, and past the motor. The air is then expelled from housing portion 25 through slots 36 in the bottom surface of base member 21.
• a gutter, generally indicated by the numeral 37, is formed above and around louvers 35. Gutter 37 is designed to protect any liquid that might be on housing portion 25,5 and in particular that might be running down rear wall 29, from being received by the air intake louvers 35.
• Gutter 37 thus includes a top portion 38 positioned above louvers 35 to collect any such liquid, and opposed side portions 39 which allow the liquids to leave rear wall 29. As such, any liquids which might have otherwise been drawn into housing portion 25 through o louvers 35, to the detriment of the motor contained therein, is drained away from the louvers 35 and the motor is thereby protected.
• Platform portion 26 of base member 21 includes a front wall 40 having a control panel 41 , opposed side walls 42, and a top surface 43 extending between front wall 40, side walls 42, and front wall 28 of housing 5 portion 25.
• the back of platform portion 26 is open and communicates with the inside of housing portion 25.
• Control panel 41 may include any number of conventional controls such as an on/off switch 44, a motor speed control 45, and/or a motor pulsing button 46.
• the top surface 43 of platform portion 26 is o provided with a pedestal 47 which carries four locator pads 48 (two shown) to receive the corners of the bottom of container 22, and is provided with a coupler 49 to attach the motor to the container 22 as will be hereinafter described.
• Pedestal 47 is also provided with at least one drainage channel 50 to direct any present liquid away from coupler 49.
• Blender container 22 may be made of a clear plastic material, such as a copolyester or polycarbonate material, and includes a bottom surface 51 and a sidewall or sidewalls 52 extending upwardly therefrom to form an open top. A rim 53 extends outwardly from the periphery of the open top at the top of the sidewalls 52. Sidewalls 52 are shown as being generally circular in configuration and thus, in essence, only one continuous sidewall is shown. However, the container 22 could take on any configuration, such as square and therefore having four sidewalls, without departing from the concepts of the present invention.
• a clear plastic material such as a copolyester or polycarbonate material
• a generally circular sidewall 52 is provided, as shown, it may be provided with a plurality of generally vertically extending ribs 54 which generally provide strength to the sidewall 52, enhance the mixing of foods, and also are aesthetically pleasing.
• the addition of strength to the sidewall 52 and the enhancement of mixing can be important particularly when large volume containers 22 are provided.
• food processing assembly 20 may have particular applicability to the commercial environment of a hospital or an assisted living establishment.
• a container 21 of a capacity of a gallon and a half or more may be provided.
• a blender blade 55 (Fig. 5) is conventionally carried on a shaft 56 near the bottom surface 51 of container 22.
• a base skirt 52 extends downwardly from bottom surface 51 and is generally rectangular in nature so as to fit over locator pads 48 on base platform 26.
• shaft 56 extends through bottom surface 51 and has a conventional splined end 58 which is adapted to be received by coupler 49.
• a number of structural ribs and the like, generally indicated by the numeral 59, are provided within skirt 57 and around splined shaft end 58.
• Container 22 is shown as having a handle 60 carried near the top of sidewall 52 and a pouring spout 61 is formed at the top of sidewall 52 at a location generally diametrically or otherwise opposed to handle 60.
• heat shield 62 includes a body portion 63 which is attached to a portion of container sidewall 52 at an area under spout 61 extending from spout 61 to the bottom of sidewall 52 terminating at skirt 57. Body portion also extends approximately one quarter of the circumference of sidewall 52. Heat shield 62 also includes a safety flap 64 spaced from body portion 63, and a generally horizontal top portion 65 interconnects flap 64 and body portion 63. Top portion 65 thus extends outwardly from near the top of body portion 63 at the sides of pouring spout 61. In addition, heat shield 62 may also be extended, as at 66, to cover the bottom and the outer sides of the spout 61.
• container 22 is intended to be quite large, as previously described, it may be difficult to pour liquid through the spout 61 by only holding the handle 60, particularly if container 22 is full of liquid. In this situation, the usual tactic of the user is to grasp the handle 60 with one hand and place the other hand on the sidewall 52 under the spout 61. However, if container 22 is holding a hot liquid, as may often be the case, in the prior art such a procedure could prove harmful or at least uncomfortable to the user's hand which could either be irritated or burned by contact with the sidewall or by drippings from the spout. However, the heat shield 62 of the present invention prevents such harm. As can be seen in Figs.
• Container cover 23 is formed of a resilient or elastomeric material such as most known thermoplastic elastomers (TPE's).
• TPE's include, for example, thermoplastic olofin rubbers, thermoplastic vulcanizates, and thermoplastic elastic block copolymers. These materials are particularly suited for cover 23 as they all inhibit the elastomer properties required for cover 23.
• Cover 23 is configured to match the configuration of the open top of container 22 and thus, in the embodiment shown, it includes a round sidewall 5 67 having a shoulder 68 which is adapted to rest on the rim 53 of container 22.
• the lower portion 69 of sidewall 67 extending below shoulder 68 is adapted to snuggly fit within the inside of container 22, and as shown in Fig. 6, at the area of spout 61 , sidewall portion 69 closes spout 61.
• Cover 23 includes a top portion 70 extending between its sidewalls 67 which is dished out, as at 71 ,o and provided with a central aperture 72.
• Aperture 72 is normally closed by a plug (not shown), but when open provides access to the inside of the container 22 should stirring or the like be desired.
• Cover 23 is shown as having two diametrically opposed tab assemblies, generally indicated by the numeral 73, located at the area of5 shoulder 68. While two tab assemblies 73 are shown, it will be evident that the present invention would only require one tab assembly 73 or, alternatively, more than two could be provided.
• Each tab assembly 73 includes a body portion 74 connected to the sidewall 67 of cover 23, as by strip 75 formed adjacent to shoulder 68.
• a notch 76 is formed in body portion 74 below strip o 75, and a handle portion 77 of tab assembly 73 extends upwardly angularly outwardly from body portion 74 at an angle of preferably about forty-five degrees. Handle portion 77 is provided with a finger hole 78 therethrough.
• Cover 23 is shown as being fully engaged by container 22 in Fig. 7. As such, container rim 53 is received in cover notch 76 and the lower portion5 69 of cover sidewall 67 is engaging the inside of container sidewall 52.
• Fig. 8 shows the manner in which cover 23 may be released from container 22. That is, the handle portion 77 of one of the tab assemblies 73 is lifted from the chain line position to the full line position. This can be conveniently accomplished by placing one's finger in hole 78, but such is not required as long as handle 77 is o being lifted. The upward movement of handle 77 only slightly flexes strip 75 until the rim 53 is released from the notch 76.
• handle 77 This same upward movement of handle 77 also moves the cover 23 upwardly so that it may then be removed from container 22 as shown in Fig. 9.
• a handle was flexed to unlatch the cover from the container but had to be continued to be flexed to remove the cover. But in the present invention, the single slight movement accomplishes both functions.
