Abstract
A dispensing device for substances including personal care, cosmetics, and medicinal substances dispenses a metered amount by actuation of a push button which indirectly contacts an advancable shaft, thereby driving a piston to push the substance from a reservoir into an applicator. The device can be operated in one hand of a person and is devoid of any twist or rotation mechanism.
Claims38
A dispensing device comprising:
- an upper portion having a housing;
- a center substance reservoir portion connected to said upper portion;
- and
- a lower cap portion connected to the center portion and containing an applicator;
- wherein an inner surface of said upper portion housing is capable of contacting a plunger, said plunger operatively providing forward movement to a center toothed shaft, thereby driving a piston head in order to dispense a substance from said applicator;
- wherein the plunger includes a hollow cylindrical portion and wherein the center toothed shaft extends through at least a portion of the hollow plunger.
3 more elements
A dispensing device, comprising:
- a slidable upper housing, an internal shaft, a substance reservoir, and an applicator;
- said upper housing operatively connected to said shaft other than at an end portion of the shaft, said shaft having a second end connected to a piston head located in said substance reservoir so that upon pressing said slidable upper housing said piston is capable of supplying a substance through said applicator connected to said reservoir, wherein a first spring is operatively connected between the upper housing and an outer cylinder, wherein the first spring maintains the upper housing a distance away from an end of a plunger in a non-depressed condition, and wherein a second spring is operatively connected between the outer cylinder and the plunger which maintains the plunger a distance away from an internal flange of the outer cylinder when the upper housing is in the non-depressed condition.
