Abstract:
In dispensing the high viscosity fluids, there used to be a inconvenience, due to the build-up growth around the throat of the container during it&#39;s usage. The upright piece(s) build in (or attached on) the closure of present invention separates out the build-up from the container throat by turning/twisting the closure. It fresh opens the throat.

Description:
BACKGROUND OF INVENTION 
       [0001]    Present invention generally relates to the closure for the dispenser of fluids and materials, specifically the cleaning mechanism of the build-up built in (or attached on) the closure for high viscosity fluids and materials (such as viscous chemicals (for example, cleanser, paste) foods (for example, ketchup, mustard, mayonnaise, shortening), etc.) 
         [0002]    In dispensing the high viscosity fluids and materials which are mentioned in the above, there used to be a inconvenience, due to the build-up growth around the throat of the container during it&#39;s usage. 
         [0003]    When the dispenser employs the flow reduction method of orifice type, a build-up tends to significantly block the flow of fluids and materials. 
         [0004]    There is a different type of dispenser (for high viscosity fluids and materials) in the market, It employs valve on the bottom of the container. One of examples is SoftScrub. 
         [0005]    It provides the user with initially quicker dispensing. But it does not suction the air well for the next pumping, even when substantial amount of contents is remaining in the container. 
       SUMMARY OF THE INVENTION 
       [0006]    The closure made by employing the cleaning mechanism of the present invention provides the user of the dispenser with easy cleaning the build-up which is blocking the flow of fluids and materials at the throat of the dispenser. The piece(s) (or block(s)) built in (or attached on) the closure of present invention separates the build-up of the fluids and materials (located at the throat of the container) from the throat of the container, when the user turns (or twists) the closure. Therefore it fresh opens the throat of the container, resulting in allowing enough flow of fluids and materials easily and repeatedly. 
         [0007]    The closure which employs the present invention, suctions the air well from the top side of the container, for the next pumping. It pumps out the fluids and materials well repeatedly, although it may takes initially longer time for the fluid and materials to move down to the mouth of the container. 
         [0008]    The present invention also provides the designer of the dispenser, with more flexibility and freedom in design than the bottom valve type dispenser does. For example, To add elegance in design. 
         [0009]    In order to make the stable dispenser (in view of gravity force), the dispenser which employs valve on the bottom of the container is not very stable on the shelf and also requires larger closure on the bottom of the dispenser. The larger closure requires more materials and more cost to make. 
         [0010]    On the other hand, the closure which employs present invention, requires less materials and less cost to make. 
         [0011]    The present invention can be made economically by (but not limited to) plastic. 
         [0012]    When the piece(s) or block(s) of present invention is made separately from the closure itself, the piece(s) (or block(s)) of the present invention can be easily attached to the closure by the user after the user bought the product. 
         [0013]    (This saves the manufacturer&#39;s production cost)

         [0065]    It should be evident that the above cases are by way of examples of cleaning mechanism and that various different types of cleaning pieces (or blocks) may be made as long as they do not substantially block the flow of the fluids, materials. 
         [0066]    It is also evident that the closure, employing the said mechanism may be combined with hinge-cap (for example). But it is not limited to hinge-cap.
