Abstract
A two-part dispenser for attachment to the bottom of a cylindrical container for dispensing a pre-calibrated amount of powdered or granular product from the container by twisting or rotating one part of the dispenser with respect to the container. The dispenser comprises a generally cup-shaped member adapted to engage the bottom of the container in fixed relationship therewith and a chambered member that fits within the cup-shaped member and can be rotated with respect to the cup-shaped member to dispense product.
Claims12
A dispensing container comprising:
- a cylindrical container body having an open bottom end;
- a cup-shaped member fixedly attached to the open bottom end of the cylindrical container body, said cup-shaped member having a substantially planar top with at least one hole disposed therein and a peripheral sidewall extending downward from the substantially planar top, the sidewall having an opening disposed therein;
- and
- a chambered member rotatably attached to the cup-shaped member, said chambered member having a substantially planar top abutting the substantially planar top of the cup-shaped member, a hole disposed in the substantially planar top, a peripheral sidewall extending downward from the planar top, the sidewall having an opening disposed therein, and a bottom disk affixed to the chambered member sidewall, the chambered member top, sidewall and bottom disk defining a cavity;
- wherein rotating the chambered member with respect to the cup-shaped member until the hole in the chambered member aligns with the hole in the cup-shaped member causes product within the container body to enter the cavity when the container is substantially upright, and further rotating of the chambered member until the sidewall opening in the chambered member aligns with the side wall opening in the cup-shaped member causes product in the cavity to be dispensed.

A dispensing container comprising:
- a cylindrical container body having an open bottom end;
- a cup-shaped member fixedly attached to the open bottom end of the cylindrical container body, said cup-shaped member having a substantially planar top with two holes disposed therein and a peripheral sidewall extending downward from the substantially planar top, the sidewall having an opening disposed therein;
- and
- a chambered member rotatably attached to the cup-shaped member, said chambered member having a substantially planar top abutting the substantially planar top of the cup-shaped member, a peripheral sidewall extending downward from the planar top, a bottom disk affixed to the chambered member sidewall, the chambered member top, sidewall and bottom disk defining a cavity, said chambered member further comprising interior walls dividing the cavity into two chambers having predetermined volumes, said chambered member further comprising a hole disposed in the planar top above each chamber and an opening disposed in a portion of the sidewall corresponding to each chamber;
- wherein a desired volume of product can be dispensed by rotating the chambered member until the hole above the chamber having the desired predetermined volume is aligned with a hole in the cup-shaped member planar top, thereby allowing product within the container body to enter the chamber, then further rotating the chambered member until the opening in the sidewall of the chamber having the desired predetermined volume is aligned with the opening in the cup-shaped member, thereby causing the product in the chamber to be dispensed.
