Abstract
A measuring dispenser wherein a generally cylindrical drum having a transverse wall is positioned at the bottom of a canister, and a longitudinally movable partition with a transverse wall is inserted within the drum so that variable volume measuring chambers are provided by longitudinally moving the partition within the cylindrical drum.
Claims15
A measuring dispenser comprising:
- a. a canister having bottom wall means;
- b. a first curved guide positioned at said bottom wall means;
- c. a second curved guide positioned at said bottom wall means in line with the first curved guide;
- d. an enlarged opening provided in the bottom wall means of said canister between the first and second curved guides;
- e. a rotatable dispensing drum having a transverse wall and an enclosing side wall, said dispensing drum being positioned for rotational movement within said curved guides;
- f. an enlarged dispensing aperture formed in the enclosing side wall of said drum for cooperation with the enlarged opening formed in said bottom wall means;
- g. a slot provided in the transverse wall of said dispensing drum;
- h. a partition for separating said drum into variable measuring chambers, the partition including a generally longitudinal member having a width slightly less than the inside diameter of said drum and a transverse wall formed at one end of said partition, said partition being inserted within said drum with the longitudinal member extending through the slot in the transverse wall of the drum and the transverse partition wall being positioned within the other end of said drum whereby variable measuring chambers are formed between the transverse wall of the drum, the longitudinal partition member and the transverse partition wall;
- and
- i. means for moving the partition including the longitudinal member and the transverse partition wall in order to move the transverse partition wall toward and away from the transverse wall of the dispensing drum whereby to vary the volume of the measuring chambers that are provided between the transverse walls and the longitudinal member, the longitudinal partition member being slidable in the slot of the transverse wall of the drum as the transverse partition wall is being moved.

A measuring dispenser comprising:
- a. a canister having a generally vertical wall and bottom wall means;
- b. a circular guide positioned on the generally vertical wall of the canister;
- c. an opening provided in the bottom wall means of the canister;
- d. a rotatable dispensing drum positioned adjacent to the opening provided in the bottom wall of the canister;
- e. a dispensing chamber provided within said dispensing drum;
- f. a dispensing aperture provided in said dispensing drum;
- g. a knob for rotating the drum in order to dispense material through the aperture in the dispensing drum, said knob including drive means;
- and
- h. a counting ring positioned between the knob of the dispensing drum and the circular guide, said counting ring including driven means that is engaged by the drive means that is provided on said knob for incrementally rotating said counting ring to indicate the number of volumes that have been dispensed from the dispensing chamber that is provided in the dispensing drum.

A measuring dispenser comprising:
- a. a canister having a front wall, a rear wall and bottom wall means;
- b. a front guide having a curved opening positioned at said bottom wall means;
- c. a rear guide having a curved opening positioned at said bottom wall means in line with the curved opening formed in the front guide;
- d. an enlarged opening provided in the bottom wall means of said canister between the front and rear guides;
- e. a generally cylindrical dispensing drum having a transverse wall integrally formed with a generally cylindrical side wall, said dispensing drum being positioned for rotational movement within said front and rear guides;
- f. a first enlarged dispensing aperture formed in the cylindrical wall of said drum for cooperation with the enlarged opening formed in said bottom wall means;
- g. a second enlarged dispensing aperture formed in the cylindrical wall of said drum diametrically opposite to the first enlarged aperture;
- h. a diametrical slot provided in the transverse wall of said dispensing drum;
- i. a partition for separating said drum into two variable measuring chambers, the partition including a generally longitudinal flat plate having a width slightly less than the inside diameter of said generally cylindrical drum and a transverse wall integrally formed at one end of said partition arranged generally perpendicular to said longitudinal plate and having a diameter slightly less than the inside diameter of said drum, said partition being inserted within said drum with the longitudinal plate extending through the slot in the transverse wall of the drum and the transverse partition wall being positioned within the other end of said drum whereby two variable measuring chambers are formed between the transverse wall of the drum, the longitudinal flat plate and the transverse partition wall;
- and
- j. means for moving the partition including the longitudinal flat plate and the transverse partition wall in order to move the transverse partition wall toward and away from the transverse wall of the dispensing drum whereby to vary the volume of the two measuring chambers that are provided between the transverse walls and the longitudinal flat plate, the longitudinal flat plate being slidable in the slot of the transverse wall of the drum as the transverse partition wall is being moved.
