Abstract
A dispensing device for storing and dispensing oils and other viscous liquids is provided. The device comprises an elongate body member and a dispensing tip. The dispensing tip comprises a valve member that is biased toward a closed position to prevent unwanted egress of device contents. In order to dispense device contents, a force is applied to the contents within the device, and that force is transmitted to the valve member to urge the valve member toward a temporary open position and allow contents to be dispensed.
Claims20
A dispensing device for dispensing fluids, oils and viscous liquids, the device comprising:
- an elongate body member comprising a first end and a second end;
- the first end comprising a user interface, and the second end comprising a dispensing tip;
- an interior volume for storing a first predetermined amount of fluid, the interior volume at least partially disposed between the user interface and the dispensing tip;
- the user interface provided in communication with a plunger, the plunger comprising a surface for applying a compression force to the first predetermined amount of fluid;
- the dispensing tip comprising a biasing member in force-transmitting communication with the dispensing tip and a ball bearing, the biasing member biasing the ball bearing toward a closed position;
- and
- wherein activation of the user-interface provides a compression force to the first predetermined amount of fluid and the forces the valve member to an open position to allow for a second predetermined amount of fluid to be dispensed from the dispensing tip.
A dispensing device comprising:
- an elongate body member;
- a dispensing tip provided on one end of the elongate body member;
- a user interface provided on a second end of the elongate body member;
- an interior volume provided within the elongate body member, the interior volume at least partially disposed between a user interface and the dispensing tip;
- the user interface provided in communication with a plunger, the plunger comprising a surface for applying a compression force to at least one of an oil and a fluid stored in the interior volume;
- the dispensing tip comprising an outlet for dispensing contents from the device, and the tip comprising a biasing member in force-transmitting communication with a stopper;
- an annular collar member comprising an aperture;
- wherein the biasing member is operable to bias the stopper against a circumference of the aperture of the annular collar member to create a seal between the stopper and the annular collar member;
- a fluid flow path extending from the interior volume to the outlet of the dispensing tip, and wherein the stopper is provided in the fluid flow path;
- wherein activation of the user-interface provides a compression force to the at least one of an oil and a fluid and forces the stopper to an open position.
A dispensing device for dispensing fluids, oils and liquids, the device comprising:
- an elongate body member having a reservoir for storing fluid;
- a dispensing tip provided on one end of the elongate body member;
- a user interface provided on a second end of the elongate body member and in communication with a plunger, the plunger operable to expel stored fluid from the reservoir;
- the dispensing tip comprising a flow path including an outlet for dispensing stored fluid from the dispensing device, and the dispensing tip comprising a ball bearing operable to create a seal in the flow path;
- an annular collar comprising an aperture;
- wherein the ball bearing is biased against an internal circumference of the aperture of the annular collar to create a seal between the ball bearing and the annular collar and to restrict fluid flow through the flow path;
- wherein activation of the user interface is operable to provide a force to a stored fluid and force the ball bearing to an open position to allow the stored fluid to be dispensed from the dispensing tip.
The dispensing device of claim 16, further comprising a coil spring and wherein the coil spring biases the ball bearing against the annular collar.
