Claim:
A dispenser for measuring and dispensing powder materials, comprising: a powder container for containing said powder materials therein, wherein said powder container has a bottom opening, a slide housing, a slide, and an elastic unit, said slide housing having a through powder inlet slot communicating with said bottom opening of said powder container and in such a manner that when said slide housing is coupled at a bottom side of said powder container, said bottom opening is aligned with said powder inlet slot, said slide having a measure slot that a predetermined amount of said powder materials is filled and measured in said measure slot, wherein said slide is movably coupled with said slide housing at a position that said elastic unit applies an urging force at said slide to retain said slide in position, wherein said slide housing comprises a slide body and a retention panel, wherein said powder inlet slot is a through slot provided at said slide body, wherein said retention panel is coupled at a bottom side of said slide body and has a through hole communicating with said powder inlet slot, wherein said slide comprises a blocking panel and a blocking wall extended from one side of said blocking panel, wherein said elastic unit has a U-shaped cross section securely clamping with said retention panel and said slide such that said urging force is applied to minimize a clearance between said retention panel and said blocking panel, wherein said elastic unit comprises a first holding panel and a second holding panel, wherein said first and second holding panels clamp with side edges of said retention panel and said blocking panel at a position that said side edges of said retention panel and said blocking panel are sandwiched between said first and second holding panels, wherein said slide is adapted to move between a first position and a second position, wherein at said first position, said measure slot of said slide is in alignment with said powder inlet slot of said slide housing for said powder materials being filled into said measure slot through said powder inlet slot, and at said second position, said measure slot of said slide is moved away from said powder inlet slot of said slide housing for discharging said powder materials from said measure slot of said slide.
