THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED


FIELD OF INVENTION
The present invention relates to a dispenser for holding and dispensing products.
DEFINITIONS
The term "product" in the context of the present invention includes viscous material typically in the form of gel and particulate material typically in the form of powder.
BACKGROUND OF THE INVENTION
Cosmetic have been in use since the ancient Egyptian civilization. However, there has been a problem in regards to storing of cosmetic substances and gel since the advent of the popularity of rouge in the time of Louis XIV and the invention of gel for various purposes such as liquid soap, hair gel and the like, almost a century ago. As "necessity is the mother of invention" man has invented dispenser for storing and dispensing products. Over the years, several types of dispensers have been made. A simple dispenser is made up of two separate parts, namely, a container for containing the product and a lid.
One type of dispenser involves dispensing the product by simply removing the lid from the container by screwing movement. The disadvantage of such a dispenser is that consumer has to utilize both the hands in order to open and close the dispenser. Moreover, such dispensers are not suitable for withdrawing products such as powder or gel in the required quantity.
2

A second type of dispenser delivers product from a container underneath a cosmetic brush bristles and through the body of the bristles to the tips. With this mechanism, brushes contain powder on the main portions of the bristles as well as the tips. Since the user only uses the bristle tips when applying the powder, powder carried on main body of the bristles are not used. Therefore, not only the brushes are messy, the product of the container is also powder is wasted.
Several attempts have been made to manufacture containers for containing powder and gel.
Accordingly, US Patent 5107871 discloses a container wherein a tray is used to contain the product and a lid is provided for covering the tray. A separate compartment is provided for containing an applicator. One disadvantage of the US Patent 5107871 is that the product contained in the tray is likely to be exposed very frequently during usage and as such leads to contamination of the product which may render the product harmful for usage.
Again, US Patent 5,515,875 discloses a container for the storage and dispensing of product which includes a base portion for accommodating and storing loose cosmetic powder. The base portion defines an opening and a closed end, A retainer engages with an opening defined by the base portion. The retainer includes a lower perforated panel which provides for a controlled dispensing of the products and an upper closure panel which folds downward and closes the lower perforated panel to seal the powder below the upper closure panel when the compact is not in use. One disadvantage of the container of US Patent 5,515,875 is that it is complex in construction
3

and involves a closing panel which is required to be folded in order to close the perforated panel. Another disadvantage of US Patent 5,515,875 is that it is not easy to operate.
Hence, there was a need for a dispenser which helps in efficient storage of products and at the same time overcomes the disadvantage of the prior art.
OBJECT OF THE INVENTION
An object of the present invention is to provide a dispenser which is easy to operate.
Another object of the present invention is to provide a dispenser which is easy to manufacture.

The lever 32 is provided with a load arm 36a and an effort arm 36b. The load arm 36a includes a tongue member 34 and a first lever arm 39a. The tongue member 34 is attached to one end of the first lever arm 39a with the help of a live hinge 37. The live hinge 37 provides a flexible joint between the first lever arm 39a and the tongue member 34. Perforations of a third set 18c are defined on the tongue member 34. The perforations of the third set
9

18c of the tongue member 34 are either an array of holes or at least one hole. The tongue member 34 is adapted to be displaced in the space between the perforated face 17 of the canister 12 and the flat wall 28 of the lid 26. The effort arm 36b of the lever 32 includes a pusher 35 and a second lever arm 39b. The pusher 35 is attached to one end of the second lever arm 39b. The pusher 35 is adapted to be displaced along the pedestal 21 of the canister 12. A fulcrum 33 is formed at the intersection of the free ends of the first lever arm 39a and the second lever arm 39b. The lever 32 is adapted to be resiliently displaced from an inoperative configuration shown in figure 1 to an operative configuration shown in figure 2. In the inoperative configuration of the lever 32, shown in figure 1, the perforations of the third set 18c is not aligned with the perforations of the first set 18a and the perforations of the second set 18b. In the operative configuration of the lever 32, at least some of the third set 18c of perforations is aligned with at least some of the first set 18a of perforations and the second set 18b of perforations for dispensing the product stored in the canister 12 through the second set 18b of perforations. The lever 32 is displaced to the operative configuration, shown in figure 2, from the inoperative configuration, shown in figure 1, on the application of force on the pusher 35. During the movement of the lever 32 from the inoperative configuration to the operative configuration, the load arm 36a and the effort arm 36b is provided with an angular movement. However, the angular movement of the load arm 36a and the effort arm 36b is converted into a horizontal movement of the tongue member 34 and causes the tongue member 34 to be horizontally displaced between the first stopper 19a and the second stopper 19b. Hence, the first stopper 19a of the lid 26 helps in restricting the movement of the lever 32 in the operative configuration and thus prevents the movement of the tongue
10

member 34 of the lever 32 beyond the first stopper 19a. Similarly, the second stopper 19b of the lid 26 helps in restricting the movement of the lever 32 in the operative configuration and thus prevents the movement of the tongue member 34 of the lever 32 beyond the second stopper 19b. In order to move the tongue member 34 back to the inoperative configuration form the operative configuration, a resilient spring 38 is provided on the load arm 36a of the lever 32. The resilient spring 38 cooperates with the load arm 36a. The resilient spring 38 is located between the load arm 36a and cylindrical wall 30 of the lid 26. Alternatively, the resilient spring 38 is located between the load arm 36a and the canister 12. The resilient spring 38 is either formed on the load arm 36 of the lever 32 or the resilient spring 38 is provided as a separate element. The resilient spring 38 is selected from a group consisting of a lateral extension from the lever 32, a compression spring and a damper.
