Dispenser
A dispenser has a reservoir to hold a fluid, in at least one embodiment a viscous cosmetic, with a pump and a set of groove protrusions attached integrally. The dispenser fits within an outer casing that houses the reservoir and has a set of grooved passages with a flat upper section, a flat lower section, and a slope in between which seat the set of groove protrusions. The dispenser is raised and lowered within the outer casing with a hollow rotating body that has a set of straight grooves that simultaneously seat the set of groove protrusions so that when the hollow rotating body is twisted on top of the outer casing, the dispenser can move up or down. The hollow rotating body also has a notch to seat a button and nozzle actuating top when the dispenser is rotated to its lowest position. When the button and nozzle are depressed, fluid is dispensed through the nozzle. More or less fluid is dispensed depending on how high the dispenser is raised with respect to the outer casing.
1. A dispenser, comprising a container ( 2 ) to store contents therein, a dispenser cap ( 10 ) coupled to an upper end of the container ( 2 ) to pump the contents, a button ( 20 ) coupled to an upper end of the dispenser cap ( 10 ) so as to be movable in a longitudinal direction, with a nozzle ( 22 ) provided at a predetermined position in the button ( 20 ), and an outer casing ( 30 ) surrounding an entire portion of the container ( 2 ), wherein a plurality of guide slots ( 32 ), upper ends of which differ in height from each other, and lower ends of which are coupled to each other, is formed in an upper end of the outer casing ( 30 ), with a horizontal extension slot ( 34 ) extending from an upper end of each of the plurality of guide slots ( 32 ), a hollow rotating body ( 40 ) is rotatably coupled to the upper end of the outer casing ( 30 ), with a guide groove ( 42 ) formed in a circumferential inner surface of the hollow rotating body ( 40 ) in a longitudinal direction, and a guide protrusion ( 11 ) is provided on a circumferential outer surface of the dispenser cap ( 10 ), the guide protrusion ( 11 ) being inserted into the guide groove ( 42 ) through a corresponding guide slot ( 32 ), so that, when the hollow rotating body ( 40 ) is rotated with respect to the outer casing ( 30 ) in one direction, the guide protrusion ( 11 ) of the dispenser cap ( 10 ) is moved upwards or downwards, along the corresponding guide slot ( 32 ) and the guide groove ( 42 ) to move the button ( 20 ) coupled to the upper end of the dispenser cap ( 10 ) upwards or downwards and is inserted into a corresponding horizontal extension slot ( 34 ), thus adjusting a height to which the nozzle ( 22 ) of the button ( 20 ) is protruded from the hollow rotating body ( 40 ), thereby adjusting an amount of the contents that is discharged, the hollow rotating body ( 40 ) including a seating notch ( 46 ), through which the nozzle ( 22 ) of the button ( 20 ) is seated into the hollow rotating body ( 40 ) when the hollow rotating body ( 40 ) is at a lowest position.
