Abstract
A powder-dispensing system includes a first rollable member and a second rollable member. The first rollable member has a first pressure surface, a threaded interior chamber internal to the first pressure surface and an entrance to the threaded interior chamber. The second rollable member has a second pressure surface and an interior chamber internal to the second pressure surface. A threaded exterior surface external to the interior chamber is configured for interlocking/threaded engagement with the threaded interior chamber. A plurality of perforations extend through the threaded exterior surface into the interior chamber of the second rollable member.
Claims19
A dispensing rolling pin, comprising:
- a first rollable, pressure-applying member having:
- a first handle at a first end;
- a first pressure surface adjacent to the first handle;
- a threaded interior chamber internal to the first pressure surface;
- and
- an entrance to the threaded interior chamber at a second end opposite the first end and spaced from the first handle by at least a length of the first pressure surface;
- and
- a second rollable, pressure-applying member having:
- a second pressure surface;
- an interior chamber;
- adjacent to a first end, a threaded exterior surface external to the interior chamber and configured for mating engagement with the threaded interior chamber;
- a plurality of perforations formed through the threaded exterior surface into the interior chamber of the second rollable, pressure-applying member;
- and
- a second handle at a second end opposite the first end of the second rollable, pressure-applying member and spaced from the threaded exterior surface at least by the second pressure surface;
- wherein (i) in a first configuration, the threaded exterior surface is fully inserted into the threaded interior chamber where the first pressure surface and the second pressure surface form a single, continuous pressure surface;
- (ii) in a second configuration, the threaded exterior surface is partially inserted into the threaded interior chamber where one or more of the plurality of perforations are uncovered;
- and (iii) the dispensing rolling pin being rollable in the first configuration and the second configuration.

A method for dispensing, comprising:
- providing a first rollable, pressure-applying member having:
- a first handle at a first end;
- a first pressure surface adjacent to the first handle;
- a threaded interior chamber internal to the first pressure surface;
- and
- an entrance to the threaded interior chamber at a second end opposite the first end and spaced from the first handle by at least the first pressure surface;
- and

- a plurality of perforations through the threaded exterior surface into the interior chamber of the second rollable, pressure-applying member;
- and
- a second handle at a second end opposite the first end of the second rollable, pressure-applying member and spaced from the threaded exterior surface at least by the second pressure surface;
- providing a substance to the interior chamber internal to the second pressure surface;
- engaging the external threads with the internal threads and twisting the first rollable, pressure-applying member relative to the second rollable, pressure-applying member in a first direction until the first and second pressure surfaces form a single, continuous pressure surface;
- applying the single, continuous pressure surface to a substance to be spread and flattened and rolling the threadedly engaged first and second rollable, pressure-applying members over the substance;
- twisting the first rollable pressure-applying member relative to the second rollable, pressure-applying member in a second direction until one or more of the perforations are uncovered;
- dispensing the substance from the interior chamber through the one or more uncovered perforations;
- and
- twisting the first rollable, pressure-applying member relative to the second rollable, pressure-applying member in the first direction until the perforations are covered and the first and second pressure surfaces form the single, continuous pressure surface.
