PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the nature of this invention and the manner in which it is to be performed:

FIELD OF THE INVENTION
This invention relates to a blender. BACKGROUND OF THE INVENTION
A blender is an electrical kitchen appliance used for mixing liquids and soli foods together or turning fruit or vegetables into liquid. Typically, the blender comprises a container and a rotatable blade assembly disposed within the container. The container is adapted to detachably yet firmly seated on a motor enclosure such that the blade assembly is coupled to the motor held within the motor enclosure for rotating the blades of the blade assembly. The blender is typically used for liquidizing, wet grinding and dry grinding of various edible stuffs/ingredients. After, the above operations, the inner surface of the container along with the blade assembly there in is required to be cleaned thoroughly for a subsequent blending of different edible stuffs/ingredients. Sometimes, because of the inherent properties of the edible stuffs being mixed in the blender, deep and difficult to remove stains are formed on the inner surfaces of container and on the blade assembly. Moreover, some portions of the blade assembly and the inner surface of the container there around are not easily inaccessible and therefore removing stains/cleaning thereof is a tedious task. As such, thoroughly scrubbing/cleaning/removing stains from even the easily accessible inner .surface of the container is cumbersome, difficult and time consuming, primarily due to the limited maneuvering space available within the container.

OBJECTS OF THE INVENTION
An object of the invention is to provide a blender which is easy to clean.
Another object of the invention is to provide a blender whose inner surface ol the container is not prone to be stained easily. DETAILED DESCRIPTION OF THE INVENTION
According to the invention, there is provided a blender comprising a container and a rolatable blade assembly disposed within the container wherein the inner surface of the container and the blade assembly within the container being coated with a non-stick food grade coating.
These and other aspects, features and advantages of the invention will be better understood with reference to the following detailed description, accompanying drawings and appended claims, in which,
Fig 1 is a cross-sectional view of a container of a blender.
As shown in the figure, a blender comprises of a cylindrical container 1 and a rotating blade assembly 2 disposed within the container 1. The container 1 may be made up of either plastic, stainless steel or such other material as known to be used for forming a container 1 of a blender. The blade assembly 2 is usually positioned at the center of the base 3 of the container 1 maintaining a clearance with the inner surface 4 of the container 1. The blade assembly 2 typically includes a plurality of blades 5 extending radially towards the inner surface 4 of the container 1 and maintaining a clearance therewith. Typically, the container 1 is adapted such that when it is seated on a motor housing (not shown) of the blender, the blade assembly 2 is automatically coupled to a motor shaft (not shown) of a motor in the motor housing for rotating the blades 5 of the blade assembly 2. The entire inner surface 4 of the container 1 including the parts of the blade assembly 2 within the container 1 is

coaled with a non-stick food grade coaling 6. The non-stick Food grade coating 6 may be any coating known to be used as a food grade coating such as PTFE (Polytetrafluoroethylene), polymer concrete or TEFLON etc. The thickness of the coating 6 is usually 25 microns; however, such is not limiting and may vary depending upon the type of the coating. The coating 6 is applied by known means and method such as sand blasting of surface, applying primer and then spray-painting (he non-stick material.
The shape of the container, base of the container, blades etc may vary. The manner in which the blade assembly is coupled to the motor may also vary depending upon the design of the blender.
According to the invention, the usage of a non-stick food grade coating on the inner surface of the container and blade assembly within the container ensures that mixed/grinded stuff do not stick thereto. Thus, cleaning the container is easy and quick, usually, just by means of a splash of water, especially, the difficult to access portions within the container. No scrubbing is therefore required to the clean the container. Also, because of the non-stick coating, no hard stains are formed within (he-container by stain making ingredients such as turmeric.
Although the invention has been described with reference to a specific embodiment, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiment, as well as alternate embodiments of the invention, will become apparent to persons skilled in the art upon reference to the description of the invention. It is therefore contemplated that such modifications can be made without departing from the scope of the invention as defined in the appended claims.

We claim:
1. A blender comprising a container and a rotatable blade assembly disposed within the container wherein the inner surface of the container and the blade assembly within the container being coated with a non-stick food grade coating.
2. The blender as claimed in claim 1. wherein the non-stick coating is PTFF. (Polytetrafluoroethylene) or polymer concrete or TEFLON etc.
3. The blender as claimed in claim 1, wherein the thickness of the non-stick coating is 25 microns.
