Abstract
A butter dispenser has a dispensing mechanism for dispensing a stick of butter from a housing or container whereby the dispensing mechanism may be separate from or integrated with the housing for containing the butter. The butter dispenser further provides for a dispensing mechanism that includes an automatically retractable dispensing mechanism for reloading the butter without requiring manual retraction of the dispensing mechanism to its fully retracted state.
Claims11
A dispenser for dispensing a semi-solid substance, the dispenser comprising:
- a dispensing mechanism;
- a hollow sleeve member having an open top end and interior void for receiving and dispensing the semi-solid substance, the hollow sleeve member further having an open bottom end for engagement with the dispensing mechanism;
- the dispensing mechanism further includes an advancing knob supporting the hollow sleeve member at the open bottom end of the hollow sleeve member, the advancing knob further including a thread shaft in rotational communication with the advancing knob and a receiving platform that is in engagement with the threaded shaft, whereby the threaded shaft extends upward from the advancing knob and through at least a portion of a central portion of the void within the hollow sleeve member;
- the receiving platform is further positioned within the interior void of the hollow sleeve member and in releasable engagement with the threaded shaft such that the receiving platform moves upward along the shaft in response to the rotation of the advancing knob in one direction and moves downward along the shaft in response to the rotation of the advancing knob in another direction;
- and
- wherein the receiving platform is automatically retractable when in the fully dispensed position and further includes a retaining mechanism and a release mechanism, whereby the retaining mechanism releasable engages the threaded shaft and the release mechanism communicates with the retaining mechanism to disengage the retaining mechanism from the threaded shaft to allow the receiving platform to automatically retract to the bottom end of the hollow sleeve member.

- the retractable dispensing platform positioned within the interior void of the hollow sleeve member in engagement with the threaded shaft such that the retractable dispensing platform moves upward along the shaft in response to the rotation of the advancing knob in one direction and moves downward along the shaft in response to the rotation of the advancing knob in another direction;
- and
- where the retractable dispensing platform further includes a retaining member and a release member, whereby the retaining member releasably engages the threaded shaft and the release member, in response to the application of pressure against the release member, forces the retaining member to disengage from the threaded shaft in a manner that permits the retaining member to move freely within along the threaded shaft without rotation of the shaft.
